The coexistence of cardiovascular disease and erectile dysfunction is widespread, possibly owing to underlying endothelial dysfunction in both diseases. Millions of patients with cardiovascular disease are prescribed phosphodiesterase-5 (PDE5) inhibitors for the management of erectile dysfunction. Although the role of PDE5 inhibitors in erectile dysfunction therapy is well established, their efects on the cardiovascular system are unclear. Preclinical studies investigating the efect of PDE5 inhibitors on ischemia–reperfusion injury, pressure overload-induced hypertrophy, and chemotoxicity suggested a possible clinical role for each of these medications; however, attempts to translate these fndings to the bedside have resulted in mixed outcomes. In this review, we explore the biologic preclinical efects of PDE5 inhibitors in mediating cardioprotection. We then examine clinical trials investigating PDE5 inhibition in patients with heart failure, coronary artery disease, and ventricular arrhythmias and discuss why the studies likely have yet to show positive results and efcacy with PDE5 inhibition despite no safety concerns.

HMRI's Cardiovascular Research Scientific Director Robert Kloner, MD, collaborated on a paper published in the journal Radiology which reviews the importance of noninvasive cardiac imaging by magnetic resonance imaging (MRI) to assess the structure and the function of the heart post heart attack. MRI uses magnets to create the images which provide important information to the clinician, such as the size of the heart attack, is there a hemorrhage into the heart attack, or is there a condition known as microvascular obstruction (MVO). When a patient has MVO they have suffered damage and blockages to the small blood vessels and capillaries in the wall of the heart; this damage remains even after the major large coronary artery that was blocked during the heart attack is now unblocked. Cardiac MRI can also be used to image how the heart heals, whether the it becomes dilated, and/or how the heart functions (contracts) post heart attack, details which help predict the patient's treatment success, their likelihood of developing heart failure and/or their recovering heart function.

PASADENA, CA, July 20, 2021 – Eight 11th- and 12th-grade students from two Pasadena Unified School District high schools are having a blast while gaining potentially life-changing educational opportunities this summer in Huntington Medical Research Institutes’ (HMRI) inaugural Biomedical Research High School STEM (Science, Technology, Engineering and Mathematics) program. Launched in June, the six-week program is providing invaluable opportunities for these students to learn from and collaborate with HMRI research scientists and staff, a STEM instructor and undergraduate teaching assistant (TA) mentors from three colleges and universities.

According to HMRI Associate Professor Dr. Nicole Purcell and director of HMRI’s inaugural high school STEM program, their mission is to educate and encourage the next generation of outstanding physicians, scientists and researchers to follow their interests and continue to grow and develop toward science-related careers. “HMRI’s STEM program, which is geared toward students who may not otherwise have access to top-tier interactive educational programs in these fields, is providing participants hands-on opportunities to explore new and uncharted solutions to some of healthcare’s biggest challenges, like heart disease, Alzheimer’s and mental illness – and have fun in the process,” Dr. Purcell said. 

Program instructor Jacqueline Fonseca, who is passionate about education, equal access and making real change happen in the field of science education in low-income communities, noted that classes convene virtually and “live” (as COVID-19 protocols allow), Mondays through Fridays, from 9:00 a.m. to 1:00 p.m., through July 30.  “While we prefer meeting in person whenever possible, there are amazing virtual lab activities available now because of the need to be socially distant,” she said. “With so many different lab types available, students get experiences they might not otherwise be able to have in a lab setting.”

Fonseca elaborated that different subject matter is explored each week and includes: Research, Methods and Instrumentation; Anatomy (Brain, Heart, Lungs); Pathology and Imaging; Genetics; and Mental Health. The program will culminate with research projects and a July 30 symposium event.

Students also are benefitting from the oversight of HMRI Education Program Manager Dr. Carlos Aguirre and undergraduate TAs Ciannah Correa, Pomona College, B.S., Molecular Biology; Hunter McKenzie, Whitworth University, B.S., Health Science; and Sidhant Umbrajkar, University of California, Los Angeles, B.S., Biology.

Current student enrollees, who were selected for the program through an application process that included teacher recommendations, include: from CIS Academy – Skylar Adams (12th grade for Fall 2021) and Anthony Romero (11th grade for Fall 2021); and from Marshall Fundamental Secondary School – Haydee Angeles and Emily Martinez (12th grade for Fall 2021); and Elizabeth Alvarez, Arleth Angeles, Isaiah Gilmore and Amina Malone (11th grade for Fall 2021). 

Having already conducted dissections, explored the human anatomy using endoscopes with a laboratory “squishy human body” to simulate an endoscopy and toured HMRI’s labs, the students are giving the program rave reviews so far.

“We’re delighted that this program is being so well received by the students,” said HMRI President and CEO Julia E. Bradsher, Ph.D., M.B.A., M.S. “We can’t wait to see how this experience will impact the students – and long term how, through the seeds planted here, they will impact the world for good in the future.”

Dr. Bradsher added that start-up funds from Pasadena residents Drs. Sonia and Neil Singla, along with a three-year grant from The Confidence Foundation, have made HMRI’s STEM program for these Pasadena high school students possible.

Dr. Sonia Singla, HMRI board member and chief administrative officer for Pasadena-based Lotus Clinical Research, expressed her support for HMRI’s high school STEM program saying: “STEM has always been the future and it’s vital that all students have access to these types of programs. There is a generalized myth out there that science and technology is only for a certain type of student, and I want to debunk that and make STEM integral to all learners and curricula.

“I want kids to be exposed to STEM and demystify and normalize science and research,” she continued. “I want kids to know there is not just a prescribed path if they choose a career in science or medicine, there are many creative and innovative career choices in STEM! I’m thrilled HMRI chose to start a STEM program for local Pasadena kids ensuring ALL of our kids in our community have access and opportunities for a brighter future.”

Dr. Bradsher explained that over the past 40 years, HMRI has offered a Summer Research Program to some 515 undergraduate college students, many of whom have gone on to become physicians, scientists, engineers and researchers – some now holding prestigious faculty appointments at academic institutions around the world. “Thanks to the generosity of Drs. Singla and The Confidence Foundation grant, HMRI now is realizing its goal of making a greater impact in the community by expanding our summer programming to include underserved high school students. We couldn’t be more grateful to these generous donors.”

"Floaters" are a challenging but common issue in myopia and aging. In the clinical world they are referred to as vitreous opacities and develop as a result of collagen fibers that have massed together and create a shadow on the retina. In this study, a team of researchers including Dr. Michael Harrington, scientific director for the HMRI neuroscience program, seek treatments that directly address the collagen build up. Read the paper published April 27, 2021 in the journal Nanoscale Horizons titled - "Carbon quantum dots as a dual platform for the inhibition and light-based destruction of collagen fibers: implications for the treatment of eye floaters."

HMRI neuroscience researcher Xianghong Arakaki contributes to international experts' teamwork in two new papers that summarize the state-of-the-art detection of early dementia. These analyses illuminate changes that are captured by simply observing brain waves when individuals are resting, using equipment (EEG) that is not expensive. The EEG measures brain activity as distinct from brain structural changes, which is important because the function may change before structural changes are visible. Both papers may be used to guide clinical trials of new therapies for Alzheimer's and other dementias and are team efforts with the Alzheimer's Association's Electrophysiology Professional Interest Areas (PIA) group.

Aging. 2021 Mar 10;103:78-97. doi: 10.1016/j.neurobiolaging.2021.03.003.  In this paper, a multidisciplinary expert panel reviewed the literature and reached consensus (endorsed by the Electrophysiology Professional Interest Area (EPIA) of Alzheimer’s Association and Global Brain Consortium) about resting EEG measures associated with clinical phenotypes and neuroimaging biomarkers of Alzheimer’s disease (AD) clinical trials. 

• Paper 2: Measures of resting state EEG rhythms for clinical trials in Alzheimer's disease: Recommendations of an expert panel. Alzheimer's Dement. 2021 Apr 15. doi: 10.1002/alz.12311. In this paper, a multidisciplinary expert panel reviewed the clinical literature and reached consensus about resting EEG measures for vascular contribution to cognitive impairment (VCI) and dementia. Although these changes were not specific for VCI, they may be tested in clinical trials for biomarkers.

It is important to detect damage from Alzheimer's disease (AD) before memories are lost, and HMRI's Neurosciences research team are testing approaches to pick up early AD. Doheny Eye Center colleagues demonstrate, for the first time, that altered electrical signals from the eye can predict those individuals in our Brain Aging study whose abnormal amyloid biomarkers in spinal fluid identify them at greater risk for AD. Retinal nerve signals may offer a simpler screen than spinal fluid to identify individuals for testing treatments to prevent further brain damage.

Why migraine happens is not understood. However, HMRI’s neuroscience team’s most recent study reveals that there are specific changes in molecules within the cerebrospinal fluid (CSF) during migraine. One of them, sVCAM-1, changes more in those who have more frequent migraine. These results identify part of the major brain phenomenon of migraine and stimulate more efforts to understand what is going on and what needs to be corrected for better treatment. Read the full article in the journal Headache, entitled Evidence that blood–CSF barrier transport, but not inflammatory biomarkers, change in migraine, while CSF sVCAM1 associates with migraine frequency and CSF fibrinogen.

HMRI's Dr. Robert Kloner shares that the scientific evidence is still unclear as to whether or not red wine is good for your heart in a March 17 article in Yahool Lifestyle News - The Worst Reason to Drink Wine, says Science. While some studies have suggested that drinking red wine can lower your blood pressure and reduce your risk of heart attacks and stroke, the concern is that the findings may have been overblown. Dr. Kloner says more research is needed to determine specifically which factors are responsible for the decreased blood pressure. In the meantime, stick to the current recommendations when drinking any alcohol, even red wine - one glass for women, two glasses for men.

Liver Cirrhosis can cause widespread damage for patients, including deposits of manganese, a trace mineral, which can affect the brain. Manganese is a key mineral used by our bodies for a variety of chemical processes, including the metabolism of cholesterol and carbohydrates, but people only need it in small amounts. The HMRI research team, including Neurosciences Scientific Director Michael Harrington, MD, showed that damage from liver cirrhosis gives an altered signal intensity consistent with increased manganese deposition on MRI, which was not found in healthy controls. This method may help quantify and track treatment in patients with cirrhosis.

Huntington Medical Research Institutes' (HMRI) neurosciences research team led by senior researcher Alfred N. Fonteh had their original research on the impact of deteriorating  membrane lipids in Alzheimer's disease (AD) published in Frontiers in Neuroscience. Incomplete knowledge of brain lipid composition limits mechanistic insight into late-onset AD pathophysiology. Since age is the most significant risk factor of AD, the HMRI team propose that older neuronal cells render the amyloid precursor protein more vulnerable to abnormal processing because of deteriorating membrane lipids. We compared the lipid composition of cognitively healthy (CH) participants with normal Aß42/Tau (CH-NAT), CH with pathological Aß42/Tau (CH-PAT), and AD. We found differential metabolism of lipids in the supernatant fluid and nanoparticulate membrane fractions of cerebrospinal fluid (CSF). Whereas phosphatidylcholine accumulates in the supernatant fluid fraction, sphingomyelin accumulates in the CH-PAT group’s nanoparticulate membrane fraction. Phospholipase A₂ activity that hydrolyzes lipids is higher in AD than in the cognitively healthy groups. Sphingomyelinase activities that hydrolyze sphingomyelin are lower in AD compared to the healthy groups. Similar fasting blood and dietary lipid levels in the three clinical groups are consistent with the CSF lipid changes originating from brain pathophysiology. Our results identify increased lipid turnover in cognitively healthy participants with AD biomarkers, switching to a predominantly lipolytic state in dementia. This knowledge may be useful for targeting and testing new AD treatments.

A HMRI preclinical study points to nicotine use near or at the time of a heart attack can further increase the size of the heart attack resulting in a more significant impact on recovery. Nicotine, a major component of tobacco smoke and also often added to e-liquid, has long been associated with high blood pressure and cardiac events. However, in this study HMRI's Chief Science Officer Robert A. Kloner, MD, PhD, Neurosciences Science Director Michael Harrington MB, ChB, FRCP, and their team have uncovered that research subjects exposed to nicotine during or close to the time of their experimentally induced heart attack increased their blood pressure causing larger heart attacks that kill off more heart cells and further reduce the heart's ability to pump.

Gamma as high frequency brain activities are involved in attention, senses (smell, sight, and hearing), mental processing, and perception, which change in Alzheimer’s disease (AD). To unmask abnormal gamma power in healthy individuals at high-risk of developing AD, HMRI’s neurosciences researcher Xianghong Arakaki MD, PhD (NIA R56AG063857) led the electrophysiology core of a brain aging study that combined memory challenge with quantitative electroencephalography (qEEG). The pilot findings encourage further investigations in developing neurophysiology-based markers for identifying individuals at risk, to help improve our understanding of AD pathophysiology and were published in Frontiers In Aging Neurosciences. The brain aging study was led by Michael Harrington, MB, ChB, FRCP (L. K. Whittier Foundation).

Robert A. Kloner, MD, PhD Early results of an experimental vaping study have shown significant lung injury from E-cigarette (eC) devices with nickel-chromium alloy heating elements and were published in the Journal of American Heart Association. Robert A. Kloner, MD, PhD, chief science officer for Huntington Medical Research Institutes (HMRI) and professor of Medicine at USC, and Michael Kleinman, PhD, professor of occupational and environmental medicine at the University of California, Irvine’s School of Medicine and member of the UCI Center for Occupational and Environmental Health, led the study which was designed to explore the effect of e-cigarette and other vaping product use on the cardiovascular system.  While conducting experiments, researchers observed eC or vaping product use-associated lung injury (EVALI) immediately after switching from a vaping device with a stainless steel heating element, to one that used nickel-chromium alloy (NC). The findings were consistent, with or without the use of nicotine, vitamin E oil or tetrahydrocannabinol (THC), which have previously been thought to contribute to the life-threatening respiratory problem. The study was funded in part by the National Institutes of Health. In addition to Kleinman and Kloner, several researchers participated in the study, including HMRI researchers Jianru Shi, Wangde Dai, Juan Carreno, Jesus Chavez, and Lifu Zhao; and UCI researchers Rebecca Johnson Arechavala, David Herman, Irene Hasen and Amanda Ting.

Scientific Director of Neuroscience at HMRI, Dr. Michael Harrington, was interviewed by Medscape regarding his recent migraine study presentation at the virtual annual meeting of the American Headache Society. The breakthrough data suggests that the choroid plexuses, a special brain structure that produces spinal fluid, is the primary source of an increased molecule in people suffering from migraines. While more research is needed, these results shed light on an area of focus and could lead to improved treatments long term.

Title: APOE4 leads to blood–brain barrier dysfunction predicting cognitive decline Date: April 29, 2020 Link: https://www.nature.com/articles/s41586-020-2247-3 The APOE4 gene increases risk for Alzheimer's disease in about 15% of the population by damaging pericytes, special cells that normally protect the blood–brain-barrier. With our colleagues at USC, we find that early cognitive decline with breakdown of this barrier in individuals with the APOE4 gene is independent of Alzheimer’s amyloid and tau pathology. This research highlights that pericyte damage may be a personalized therapeutic target to treat Alzheimer's disease in 15% of the population.

While studying the mechanics of the cells, Vasudevan and her team discovered that GABAergic neuronal cells must be paired with their vascular counterpart, the embryonic forebrain specific endothelial cells for faster, effective therapy.

“In short,” says Vasudevan, “we were able to replicate the close neurovascular interactions of the developing forebrain and prove their critical role in guiding the GABAergic interneurons to their final destination in the adult brain.”
The study used a GABA pathway component - the GABAA receptor beta 3 subunit (GABRB3) to isolate and generate a new human vascular cell product. This human vasculature is unique to the embryonic forebrain and distinct from vasculature in other organs, one of the many critical findings from Vasudevan’s work at HMRI that will aide scientists in the longer journey to use cell-based therapies for brain disorders.

The concept refers to the observation that brief periods of low blood flow to the heart can result in prolonged recovery of contractile function of the heart muscle, even after blood flow has been restored. It is important as stunned myocardium can lead to heart failure. In this new article we update the concept as well as another similar concept, hibernating myocardium, which also can lead to heart failure.

FOR IMMEDIATE RELEASE: January 15, 2020  

HMRI Receives W. M. Keck Foundation Grant to Study Fluctuating Brain Function

Huntington Medical Research Institutes (HMRI) announced today a $1 million, three-year award from the W. M. Keck Foundation to help support research into a deeper understanding of fluctuating sodium in the nervous system as the root cause of fluctuating brain function.  The project will leverage HMRI’s pioneering neurosciences program that has undertaken longitudinal studies of the brain and nervous system over the past 20 years. “We are thrilled to receive this prestigious award from the W. M. Keck Foundation to fund this futuristic study”, said, Dr. Julia E. Bradsher, President and CEO of HMRI.  She further stated, “if successful, the results and their implications will be an enormous leap forward in explaining how brain fluctuations arise in both health and disease.  This truly is a great achievement for HMRI, our scientific team in the neurosciences, and our collaborators.” In this project, HMRI proposes that fluctuations of sodium in cerebrospinal fluid and brain tissue will alter neuronal firing rates and thus impact brain functions, whose features vary depending on the site of the fluctuation and the health of the neurons. In a healthy brain, this will change the normal synchronization between neural circuits that might then manifest as fluctuations in mood, alertness, or cognitive abilities. The study extends findings from previous research on fluctuations underlying migraine to other brain fluctuations, including Alzheimer’s disease (AD).  In the prior studies, it is suggested that sodium fluctuation may cause imperfect synchronization of brain regions, leading to abnormal sensory perception as in migraine, or difficulty recalling memories, slower problem solving, and poor decision making. “We get to test a theory that can impact everyone by explaining how brain functions fluctuate and identifying a target to correct deviations”, said Dr. Michael B. Harrington, Scientific Director of the HMRI Neurosciences Program and principal investigator on this new project.  “We are thrilled and honored to get this peer-reviewed award as our idea would be too unconventional for normal federal funding review processes.” Along with Dr. Harrington, the research will be conducted by an interdisciplinary team of scientists, including Dr. Brian Stoltz, a chemistry researcher from the California Institute of Technology (CalTech) and Dr. Linda Petzold, a mathematician at University of California, Santa Barbara. For interviews, please contact Brenda Rivas at Brenda.Rivas@hmri.org or 626-807-7079.   About HMRI Huntington Medical Research Institutes (HMRI), founded in 1952, is an independent, non-profit organization with the mission to improve lives through patient-focused scientific research.

Cognitively healthy Brain Aging study participants with spinal fluid chemistry that predicts higher risk for Alzheimer's disease (AD) had pupil responses, sleep, and circadian rhythms that were different from those at lower risk with good chemistry. These data suggest that mRGC cells reflect AD pathology before symptoms have started, and may help identify early AD.

This is called no-reflow and is a bad prognosticator, associated with death and heart failure. In this paper we provide information on how to diagnose and treat this devastating consequence of heart attacks.

Title: Potential for stem cell-derived biologic pumps for cardiovascular and other medical therapies Date: July 17, 2019 Link: https://www.futuremedicine.com/doi/10.2217/rme-2019-0056 When the heart is injured, there may be a need to improve blood flow by developing ventricular assist devices that help move blood forward.  This paper reviews our previous experience with utilizing immature heart cells implanted not into the heart but into blood vessel walls, such as the aorta or vena cava, to provide auxiliary pumps for blood flow to the organs of the body. We previously showed that immature heart cells could survive, differentiate, grow and contract when implanted as cuffs around large blood vessels; in essence, creating little hearts to help blood move through the arterial and venous system independent of the pumping ability of the main heart. Induced pluripotent stem cells could be used to develop these auxiliary pumps.

Title: Lessons learned about stress and the heart after major earthquakes Date: July 5, 2019 Link: https://www.sciencedirect.com/science/article/abs/pii/S0002870319301437 This paper is a follow up to Dr. Robert Kloner's previous work on the effect of the Northridge earthquake as a trigger of cardiovascular events. This new paper published in the American Heart Journal this week reviews thirteen major earthquakes world-wide and describes the types of cardiac events that have been associated with the emotional stress of an earthquake. There is no question that the stress of an earthquake can contribute to sudden death, heart attacks, heart failure, and high blood pressure. Our analysis helps to show the way in which perception of an event by the brain can affect the heart (the brain heart connection).

FOR IMMEDIATE RELEASE: June 5, 2019  

MEDIA RELEASE: HMRI HOSTS INAUGURAL COMMUNITY FORUM TO RELEASE FINDINGS FROM STUDY ON AGING WITH HIV

Four-Time Gold Medal Olympic Diver, Greg Louganis, to deliver keynote speech

  On Saturday, June 8, 2019, Huntington Medical Research Institutes (HMRI) will host an Inaugural Community Forum to highlight the findings from its BRAVE (Brain Aging and Vascular Etiology in HIV) study. The focus of the study is to gain a better understanding of brain and cardiovascular changes among people who are HIV positive but continue to maintain viral suppression. The study also seeks to better understand accelerated aging and increased risk for non-AIDS age-related diseases such as heart disease, liver disease, and neurocognitive decline. Infectious Disease Specialist, Dr. Kimberly Shriner of Huntington Hospital and HMRI’s Director of Imaging Research, Dr. Kevin S. King, will speak about the physician’s view on managing HIV and about the importance of the study. Moderated by Dr. Shriner, the Forum also includes a panel of five individuals living healthy lives with HIV. HMRI began the BRAVE study in 2017 to follow people living with HIV over time to better understand their heart and brain health while living otherwise healthy lives with HIV. Since the start of the study, HMRI has enrolled approximately 50 individuals and plans to continue enrolling study participants. Studying brain health with aging in HIV is difficult as many of the changes seen in the brain in HIV resemble accelerated aging.  HMRI has used a comprehensive magnetic resonance imaging evaluation that allows research scientists to distinguish the effects of HIV on the brain from the effects of aging.  It’s also been found that people with more advanced HIV infection when they initiate treatment have persistent deficiencies in brain metabolism and brain artery function even after achieving long term viral suppression.  Importantly, scientists can identify metabolic and vascular problems before any permanent damage to the brain has occurred and when health interventions have the best chance of improving long term outcomes. HMRI President and CEO, Dr. Julia Bradsher shares, “We are excited to launch this new program to engage and educate the community about our research and life-changing health conditions and diseases.” Dr. Bradsher went on to say, “We plan to make this an annual program and focus each year on a different area of HMRI’s work. We are pleased to feature the BRAVE study in this inaugural program.” Greg Louganis, four-time Gold Medal Olympic diver, speaker, author, activist, actor, humanitarian, and designer, will be the keynote speaker. The Community Forum is a free event and is open to the public. Individuals interested in attending must RSVP online at https://hmri.org/brave/. Seating is limited. Deadline to RSVP is June 5, 2019. The event is sponsored by Perkins+Will and Gilead Sciences, Inc. For interviews, please contact Brenda Rivas at Brenda.Rivas@hmri.org or 626-807-7079.

We found female methamphetamine users made more risky choices and demonstrated more nonconforming attitudes in a gambling task when exposed to the choices of their peers. This nonconformist tendency may help track and understand the addiction and decisions made by female methamphetamine abstainers.

Title: Myocardial hypothermia induced after reperfusion does not prevent adverse left ventricular remodeling nor improve cardiac function. Published: April 13, 2019 Link: https://www.ncbi.nlm.nih.gov/pubmed/30991060 The importance of this study is that it shows that hypothermia (cold) applied to the heart in the setting of heart attack results in a smaller heart attack and better healing of the heart attack and preservation of the left ventricles' shape and function if applied early, while the coronary artery is still occluded. However, if the cold is applied after the coronary artery is already opened (by stenting or angioplasty) then cold is not protective.

Professor Mihi Yang of the Department of Toxicology, College of Pharmacy, Sookmyung Women’s University, Seoul, South Korea, was a visiting scientist at HMRI from March 4-8, 2019. Professor Yang works with the Korean Center for Disease Control on oxidative stress markers of diseases and is interested in learning lipid analyses from HMRI’s scientists, after reading of Dr. Alfred Fonteh’s work from his publications. She was accompanied by her graduate student, Eunbee Kim, who expects to pursue doctoral studies in the United States. At HMRI, both researchers learned about sample preparation techniques such as extraction of lipids from fluids, hydrolysis, derivatization, and gas chromatography/mass spectrometry. It is expected that preliminary data obtained from this collaboration will lead to funding opportunities from several lending institutions.

HMRI's Dr. Alfred Fonteh attended the American Society of Biochemistry and Molecular Biology DEUEL Conference on Lipids at Dana Point, CA, from March 5-8, 2019. Dr. Fonteh presented three abstracts on the ongoing collaboration between the Neuroscience Program and Dr. Robert Cowan of Stanford University on chronic migraine research. The first abstract showed an increased breakdown of lipids in plasma obtained from patients with chronic migraine compared with control study participants. The second abstract showed that medications used to treat inflammation or pain reduced the breakdown of lipids in plasma from chronic migraine patients. The third abstract showed that conditions such as depression or obesity that are common in migraine patients were also related to the differences in plasma lipid profiles. Together, these studies show that chronic migraine patients have abnormal lipid metabolism that can be exploited by physician/scientists to monitor migraine severity, response to current medications, or to discover better treatments.

Title: Improved Long-term Survival with Remote Limb Ischemic Preconditioning in a Rat Fixed-Pressure Hemorrhagic Shock Model Published: February 12, 2019 Link: https://hmri.org/dev/wp-content/uploads/2019/02/10.1007_s10557-019-06860-6.pdf The article published in the journal Cardiovascular Drugs and Therapy was co-authored by HMRI's Drs. Wandge Dai, Jianru Shi, Juan Carreno, Robert Kloner, and Sharon Hale. This is a very important paper as it shows for the first time that remote ischemic conditioning (a procedure where one simply inflates and deflates a blood pressure cuff on the limb) can markedly improve long-term survival from hemorrhagic shock (shock due to blood loss). It is the first of HMRI's original papers from our U.S. Department of Defense (DOD) grant and could lead to novel therapies for wounded soldiers and civilians.

Title: Proceedings of the 3^rd annual Acute Cardiac Unloading and REcovery ( A- CURE) symposium Published: February 7, 2019 Link: https://bmccardiovascdisord.biomedcentral.com/articles/10.1186/s12872-019-1000-z The paper summarizes a number of studies performed in various research laboratories that focus on new devices that improve the function of the heart in settings such as heart attack. These studies were presented at the A-CURE meeting in November 2018 in Chicago, a satellite meeting just prior to the American Heart Association meetings.  Studies investigated mechanical devices that take the workload off of the heart and assist the heart in pumping blood to all of the organs of the body; when the heart has been injured. Dr. Robert Kloner's particular section is based on work that HMRI's research group ( Dr. Wangde Dai et al ) performed several years ago using living heart cells that had been transplanted into the walls of the great vessels (aorta and inferior vena cava) to serve as an auxiliary biologic pump to assist the heart.

Title: Alpha desynchronization during simple working memory unmasks pathological aging in cognitively healthy individuals

Published: January 2, 2019

Link: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0208517

The brain is damaged more than ten years before any symptoms of Alzheimer’s appear. This is detected in spinal fluid chemistry, where brain stress shows up. We want to detect this pre-symptomatic stage, which would be important to test treatments before memories are lost. This study examined whether or not we could detect this early stage, having individuals wear an EEG hat while individuals performed simple computer tests. We found those who are cognitively healthy but have stressed chemistry in their spinal fluid had to use more of their brain EEG rhythms in the test compared to those with normal chemistry.

The Men Who Wear Fitbits to Track Their Coke Benders

Human beings are innovators. You can hardly create a product before somebody’s come up with a use for it you never considered. (Even Viagra was originally developed as a pill to lower blood pressure — erections were merely a side effect.)

So I don’t think we can be too surprised that people are using fitness trackers to monitor their vitals while taking recreational drugs. As CNBC first reported, some drug users find wearable devices like the Apple Watch and the Fitbit helpful in managing their intake of stimulants, which tend to get your heart rate up. They reason that by keeping their heart below a certain threshold of beats per minute (bpm) while high, they can lessen the always-present risk of an acute cardiac event. And so, ever since the consumer technology to keep tabs on your pulse 24/7 first became available, they’ve been sharing health data from their binges in online drug forums like the r/cocaine subreddit, for example:

Clearly, you can see one of coke’s (multifarious) effects on your body in real time with these gadgets strapped to your wrist. But what is the practical value of that information, if any?

I got in touch with “X,” a 19-year-old male redditor who frequents r/cocaine and tracks his bpm while indulging in his favorite intoxicants, which include alcohol and the anti-anxiety tranquilizer Xanax, as well as coke. He says that while his Apple Watch is mostly “shitty,” its heart rate monitoring feature is “the best and most useful thing about it.” His interest in the data depends on what he’s taking, of course: “For Xanax I make sure [my heart rate] doesn’t fall under a certain number,” he explains, while with coke he wants to avoid “going over a certain number.”

And the numbers are certain. “My resting heart rate is usually 80. If I’m on Xanax I usually don’t want it dropping under 50,” X says. “And on coke, anything above 140 is when I stop. If it’s falling too low while on Xanax, then it’s okay, because I can just go take a nap and stop drinking if I was. On coke, if it starts getting too high, I’ll take a Xanax to calm my heart rate down.”

I ask X if this method of dosing feels more reliable than what most everyone else has had to do throughout the history of inebriation — go with their gut instinct. “Yes, it is,” he says, though he’ll rely on his own best judgment as well, particularly in a party setting. Speaking of which: The fitness tracker binge, like cocaine itself, is a rather social phenomenon. “The first time I did it,” X explains, was “with people who have done it for a long time, so then after I just learned from them.” Later, he got his friends with wearables to monitor their heart rates as well, and they share their bpm often, whether hanging out together or not. “Some of us have higher tolerances, so we use it to keep [tabs on] each other,” he says.

Sounds pretty responsible, doesn’t it? Dr. Robert A. Kloner, the Chief Science Officer and Director of Cardiovascular Research at Huntington Medical Research Institutes, disagrees completely. “Not a good idea,” he writes in an email when I ask him about the trend. “It will lead people to have a false sense of security.”

Not only is Kloner an expert on the heart and blood vessels, he also co-authored work on the cardiovascular effects of cocaine, which can be extreme. There’s more to worry about than how fast your heart is beating, he points out: “Cocaine can cause coronary artery vasospasm; increase the oxygen need of the heart by increasing contractility; it can cause the blood pressure to go up; it can cause arrhythmias; it can cause heart muscle cells to go into contracture; it has been associated with ruptured aneurysm, seizures, strokes and heart attacks,” he explains, adding that the drug can also “increase the aggregation of platelets.”

Unfortunately, your Apple Watch isn’t going to be much help in predicting anyof those dire outcomes. “Using heart rate monitoring devices only gives one physiologic parameter for a drug that has complicated effects on the cardiovascular system,” Kloner tells me, concluding that “the best way to avoid cocaine cardiotoxicity is to avoid cocaine to begin with.”

Naturally.

But it seems that X has figured out a system he likes, and he knows what to look for — at least as far as a decent high is concerned. If the coke is of a better quality, “rocky and scaley,” then he’ll notice a jump in bpm “almost instantly” after taking some, with a pulse fall-off 45 to 60 minutes later. “If it’s stepped on,” he says — which is to say cut with other ingredients — he gets the same instant bump, but a much quicker fall-off in heart rate, somewhere in the 10 to 15 minute range. And while he never wants to soar above 140 bpm, “around 120 is perfect for me,” he says. Apart from this niche functionality, he only uses the heart rate monitor “occasionally” while sleeping.

X isn’t too bothered about Apple having this data, either. “Well, yeah, sometimes it does feel weird,” he admits. “But at the same time, I do work out, so my heart rate is constantly at that point.” Besides, as the excitement of this year’s World Cup and other intense situations have proved, the causes of bpm surges during physical “inactivity” are varied and strange.

Even as drug users like X seek the equilibrium to their inebriation with the aid of heart rate monitoring, others are taking cues from the tech to pop their legally prescribed drugs.

After all, the point of a fitness tracker is to help you manage your health. Fitbits and Apple Watches may not make drug use safer, but these devices will improve, offering broader, deeper and more accurate analysis of what’s going on with our bodies, and owners will interpret that new information however they like.

For now, however, most would rather stay analog:

Title:

Understanding the Immune Microenvironment at the Uteroplacental Interface.

OBJECTIVES In human pregnancy, the baby is 50% non-self, but is not rejected as an allogeneic organ transplant would be. The local interaction site between mother and baby is the uteroplacental interface (UPI), where maternal decidua develops between the uterus and the fetal placenta. We seek to understand the local immune microenvironment of the UPI to identify the critical factors mediating maintenance of maternal – fetal tolerance. METHODS Using a novel, non-invasive sampling method, we isolated lymphocytes from the surgical sponge used to clean the uterus after C-section, and compared them to the peripheral blood (PB) of 3rd trimester healthy pregnant women. RESULTS The term UPI lymphocyte pool contained a similar proportion of CD3+ cells (~62%) vs. PB but within the CD3- fraction, NK cells were significantly enriched (CD56hiCD16- PB 1.86% +/- 0.36, UPI 19.84 +/- 3.14, p<0.0001. CD56loCD16+ PB 24.22 +/-4.15 UPI 50.53+/- 3.17 p<0.0001) while monocytes/macrophages were decreased (PB 22.64 +/- 1.43, UPI 6.05 +/- 0.95). Intracellular cytokines in gd T cells (IFNg, TNFa, and Granzyme A) and NK cells (Perforin A and Granzyme A) were significantly elevated at the UPI vs. PB. Further, CD56hi CD16- uterine NK cells but not PB NK cells exclusively displayed an activated (CD69+) phenotype and a significantly more of the apoptosis-inducing molecule Fas (mean PB 21.74 +/- 4.5; mean UPI 43.61 +/- 2.02 p=0.0007). CONCLUSION The dramatic differences in cell type proportions, phenotypes and functionality we observed between lymphocytes at the UPI vs PB indicate a specific local immune microenvironment that develops at the UPI. The signals – and mechanisms that attract and retain lymphocytes at the UPI are unknown but likely important for understanding of how the necessary tolerogenic environment for successful pregnancy is established and maintained. http://www.ifpa2017.org/

The Science Behind Your Mind

Dr. Harrington joined HMRI and established the Molecular Neurology Program in 1998.  He studies how the cerebrospinal fluid composition explains the intermittent disorder of migraine and the progressive neurodegeneration of Alzheimer's disease.  He also studies molecules that are transported to/from the brain in blood (including changes after mild traumatic brain injury), and those excreted in urine.  Mike enjoys collaborating with other clinical and scientific colleagues that apply complementary measure of brain function so as to gain as much information from teh same study participants.

Therapeutic Hypothermia Reduces the Inflammatory Response Following Ischemia/Reperfusion Injury in Rat Hearts

Shi J1,2, Dai W1,2, Kloner RA1,2. Author information Abstract Therapeutic hypothermia (TH) is known to protect against ischemia/reperfusion (I/R) injury. One mechanism of I/R injury includes secondary injury due to the inflammatory cascade. We hypothesized that TH reduces the inflammatory response following I/R injury. Rats were randomized to sham, normothermic, or hypothermic groups and subjected to 1 hour of coronary artery occlusion and 48 hours of reperfusion. Hypothermia was initiated, using the ThermoSuit device, 2 minutes after the onset of coronary artery occlusion to a core temperature of 32°C, and then the rats were allowed to rewarm. After 48 hours, rats in the hypothermia group demonstrated a preserved left ventricular fractional shortening by echocardiography. TH decreased the inflammatory cytokines in the risk zone of the heart, which included monocyte chemoattractant protein-1, interleukin-6, tumor necrosis factor-α, and inducible nitric oxide synthase gene expression, and altered expression of the remodeling genes of matrix metalloproteinase and tissue inhibitor of metalloproteinase. Furthermore, rat inflammatory cytokines & receptors PCR array was performed and the data showed that 71 out of 84 genes were upregulated in the risk zone of normothermia hearts versus shams. The upregulation was largely reversed in the risk zone of hypothermia hearts compared to normothermia. TH preserves cardiac function, decreases excessive inflammatory gene expression, and regulates myocardial matrix remodeling related genes.

Management of No-Reflow Phenomenon in the Catheterization Laboratory.

Rezkalla SH1, Stankowski RV2, Hanna J3, Kloner RA4. Author information: · 1Department of Cardiology, Marshfield Clinic, Marshfield, Wisconsin. Electronic address: rezkalla.shereif@marshfieldclinic.org. · 2Marshfield Clinic Research Foundation, Marshfield, Wisconsin. · 3Lund University, Lund, Sweden. · 4Huntington Medical Research Institute, Pasadena, California; Division of Cardiovascular Medicine, Department of Medicine, Keck School of Medicine, University of Southern California, Los Angeles, California. Abstract At the conclusion of a primary percutaneous coronary intervention for ST-segment elevation myocardial infarction, and after the cardiologist makes certain that there is no residual stenosis following stenting, assessment of coronary flow becomes the top priority. The presence of no-reflow is a serious prognostic sign. No-reflow can result in poor healing of the infarct and adverse left ventricular remodeling, increasing the risk for major adverse cardiac events, including congestive heart failure and death. To achieve normal flow, features associated with a high incidence of no-reflow must be anticipated, and measures must be undertaken to prevent its occurrence. In this review, the authors discuss various preventive strategies for no-reflow as well as pharmacological and nonpharmacological interventions that improve coronary blood flow, such as intracoronary adenosine and nitroprusside. Nonpharmacological therapies, such as induced hypothermia, were successful in animal studies, but their effectiveness in reducing no-reflow in humans remains to be determined.

Regarding the Super Bowl and stress… “The concerns of the stress of merely watching a game are real,” said Robert Kloner, cardiologist and researcher at Huntington Medical Research Institutes in Pasadena. Research he and his colleagues have done found that there was a connection between cardiac-related mortality rates in the hometowns of some Super Bowl teams that either won or lost. “In the hometowns of teams that lost — including Los Angeles in 1980 when the Steelers beat the Los Angeles Rams — “We found an increase in overall death and cardiac death” in the four days after the Super Bowl, he said. “But in towns that won — including Pittsburgh in 2009 when the Steelers beat the Arizona Cardinals — “circulatory-related deaths actually went down,” he said.

Robert A. Kloner, MD, PhD Bernard Chaitman, MD Abstract: Angina pectoris is defined as substernal chest pain, pressure, or discomfort that is typically exacerbated by exertion and/or emotional stress, lasts greater than 30 to 60 seconds, and is relieved by rest and nitroglycerin. There are approximately 10 million people in the United States who have angina, and there are over 500 000 cases diagnosed per year. Several studies now show that angina itself is a predictor of major adverse cardiac events. In addition, angina is a serious morbidity that impedes quality of life and should be treated. In the United States, pharmacologic therapy for angina includes β-blockers, nitrates, calcium channel blockers, and the late sodium current blocker ranolazine. In other countries, additional pharmacologic agents include trimetazidine, ivabradine, nicorandil, fasudil, and others. Revascularization is indicated in certain high-risk individuals and also has been shown to improve angina. However, even after revascularization, a substantial percentage of patients return with recurrent or continued angina, requiring newer and better therapies. Treatment for refractory angina not amenable to usual pharmacologic therapies or revascularization procedures, includes enhanced external counterpulsation, transmyocardial revascularization, and stem cell therapy. Angina continues to be a significant cause of morbidity. Therapy should be geared not only to treating the risk factors for atherosclerotic disease and improving survival but should also be aimed at eliminating or reducing the occurrence of angina and improving the ability of patients to be active.

Abstract

Kloner, R.A., Hale, S.L., Dai, W., Shi, J. Cardiovasc Drugs Ther. (2016 Oct 6) doi:10.1007/s10557-016-6691-0 The size of the myocardial infarction remains an important therapeutic target, because heart attack size correlates with mortality and heart failure. In this era, myocardial infarct size is reduced primarily by timely re-perfusion of the infarct related coronary artery. Whereas numerous pre-clinical studies have shown that certain pharmacological agents and therapeutic maneuvers reduce myocardial infarction size greater than re-perfusion alone, very few of these therapies have translated to successful clinical trials or standard clinical use. In this review we discuss both the recent successes as well as recent disappointments, and describe some of the newer potential therapies from the pre-clinical literature that have not yet been tested in clinical trials.

Got migraines? Join a Pasadena research effort that seeks a cure

LARRY WILSON SEPTEMBER 6, 2016 www.pasadenastarnews.com “We’re lucky in the Pasadena area to have world-class researchers on many diseases, and I’ve enjoyed over the years writing about the work of Scottish neurologist Dr. Michael Harrington at the Huntington Medical Research Institutes, and participating a little in some research. As he searches for causes and disease markers and possible cures for migraines, Harrington, sometimes still working with Cowan, has enlisted me in getting the word out to local migraineurs. Last time I emceed an event featuring Serene Branson, the CBS 2 reporter whose garbled speech from the Grammys five years ago made viewers think she had suffered an on-air stroke. It was instead a complex migraine, and she has become an activist about the disease, too. Have headaches, and want to join us in helping researchers make us better? Know someone who fits the bill? On Sept. 8, Harrington is recruiting people with chronic migraine and post-traumatic headache for a six-week study with a public meeting from 5:30 to 6:30 p.m. at HMRI, 99 N. El Molino Ave., Pasadena. On Saturday, Sept. 10, from 2 to 3 p.m., he’s doing the same for those 70 to 90 for a study on aging and Alzheimer’s. Interested, or have questions? Call Betty Chung, 626-795-4343. While a headache will remain a headache, when you get involved in the work to explore the causes of a disease, you’ll come to new understandings, and in doing so feel better already.” Read the rest of the article here: http://www.pasadenastarnews.com/opinion/20160906/got-migraines-join-a-pasadena-research-effort-that-seeks-a-cure-larry-wilson

A bit of salt might stop headaches’ battery of the brain

Jessica Hamzelou August 8, 2016 www.newscientist.com Could a salty diet keep migraines at bay? People who eat a lot of salt report having fewer migraines and severe headaches – the first evidence that dietary sodium may affect the condition. But the researchers caution that more evidence is needed before people change their diets, given that high salt consumption is linked to heart disease and stroke. There is growing evidence linking migraines with sodium. During a migraine, levels of sodium have been found to rise in cerebrospinal fluid, the liquid that bathes the brain and central nervous system. And sodium levels in this liquid seem to peak in the early morning and late afternoon – times of day when people commonly report experiencing migraines.

Less Salmon, More Plaques? Link Between Omega-3s and Aβ Reinvigorates Fish Oil Debate

August 12, 2016 http://www.alzforum.org/ Omega-3 fatty acids as an intervention for Alzheimer’s disease may not be dead in the water just yet. A new study may reinvigorate interest in the fish oils. Researchers led by Helena Chui at the University of Southern California have used PET and MRI scans to correlate markers of Alzheimer’s disease with blood levels of the essential fatty acid docosahexaenoic acid (DHA). They report that people with the least amount of DHA have the most amyloid and atrophy in brain regions associated with AD. The findings, published August 8 in JAMA Neurology, do not prove that DHA blocks AD pathology, however they do mesh well with animal studies suggesting the fatty acid thwarts Aβ accumulation. “The … study has the potential to rekindle interest in the therapeutic potential of DHA,” wrote Joseph Quinn of Oregon Health & Sciences University in Portland in an editorial that accompanied the paper. Quinn headed a previous DHA clinical trial, but was not involved in the current study.

Migraine Headache Causes And Symptoms 2016: Everything You Need To Know

Michael Harrington, MB, ChB, FRCP Director of Neurosciences at Huntington Medical Research Institutes (HMRI) Pasadena, California - August 8, 2016 www.medicaldaily.com Migraine is the third most common disease in the world. It costs American employers $20 billion each year, and considering how widespread and the suffering it causes are, it’s safe to say research funding is meager at best. The National Institutes of Health provides the mainstay of medical funding in the United States, about $20 million annually — but funding should be 12-fold higher if it will be comparable to research dollars allotted for other brain diseases such as schizophrenia. A ‘typical’ migraine headache is severe: One-sided, pulsing or throbbing, accompanied by severe pain and discomfort to normal lights, sounds, or smells, not to mention nausea and vomiting. It typically lasts four to 72 hours, during which the scalp can be extremely sensitive to the touch. So it’s not unusual for migraine sufferers — also known as migraineurs — to withdraw from the outside world to lie down without moving in a dark, quiet room. But the truth is, the realities of life often prevent this form of relief.

Go Nuts to Age Well: 6 Benefits of Nuts for Older Adults

K. Aleisha Fetters August 5, 2016 www.health.usnews.com

A handful a day may keep the doctor – and a slew of age-related health issues – away.

Joe Biden wants cancer researchers to share their data, and he's not mincing words. “You know the inflammation that nuts are so good at fighting? Well, that's critical to preventing cognitive decline and dementia into old age. For instance, research out of Huntington Medical Research Institutes shows that in patients with Alzheimer's disease, levels of inflammation are higher, partly due to lower levels of omega-3 polyunsaturated fatty acids, explains Alfred Fonteh, neuroscience research scientist at HMRI. Nuts, however, are rich in omega-3s, and walnuts in particular are ripe with docosahexaenoic acid, or DHA, a type of omega-3 that is a primary structural compound in the human brain. "DHA is the source of molecules that protect neurons, molecules that resolve inflammation and molecules that help repair free radical damage of tissues," Fonteh says. "What's more, monounsaturated fatty acids rich in nuts also control how toxic proteins are removed from the brain." "Therefore, a dietary source of omega-3 fatty acids and monounsaturated fatty acids from nuts may replenish what is lost in the brain and enhance the ability of the brain to remove toxic peptides that would otherwise kill neurons," he says. Case in point: In a 2015 JAMA Internal Medicine study of older adults, those who followed a Mediterranean diet supplemented with nuts over the course of six years enjoyed better cognitive function than those who ate a Mediterranean diet sans nuts.” Read the rest of the article here: http://health.usnews.com/wellness/articles/2016-08-05/go-nuts-to-age-well-6-benefits-of-nuts-for-older-adults

A higher death rate in 2015 can be attributed to three main causes, but many of those deaths could have been prevented.

Ann Pietrangelo June 9, 2016 www.healthline.com HMRI’s Dr. Harrington says although there’s currently no treatment known to slow or halt the progression of Alzheimer’s disease, that doesn’t mean there’s nothing we can do. “The important need is for a lot more research to seek an understanding of the neurodegeneration process that is occurring decades before any symptoms. HMRI and some other organizations are actively following this urgently needed approach,” said Harrington.

Dr. Michael Harrington, Director of Neurosciences at HMRI, weighs in on mechanisms that keep the brain clean during neurodegenerative diseases:

Lizette Borreli May 26th, 2016 www.medicaldaily.com Doing crossword puzzles and memory-training games and taking Omega-3 fish oil supplements are steps we take to boost our brain health. We do this to keep our mind clear and our head sharp, but how exactly does this process of cleaning differ between the healthy and diseased brain? According to a recent study published in the journal PLOS Biology, the brain “sweeps” clean dead neurons for it to function properly, but when it comes to neurodegenerative diseases, this cleaning process is impaired. There are mechanisms that keep the brain clean during neurodegenerative diseases. Typically, when neurons die, their debris needs to be quickly swept away for the surrounding brain tissue to continue functioning properly. There needs to be a balance between highly specialized cells, microglia, that respond by disposing of neurons that express "eat me" signals, according to Dr. Michael Harrington, Director of Neurosciences at Huntington Medical Research Institutes in Pasadena, Calif.

"Silent" heart attacks are a thing—and doctors say women are especially susceptible of dying from them.

Korin Miller (originally published on Self.com) “Silent heart attacks are dangerous because people who have them may not get the proper therapy for the heart attack itself and will not get the proper therapy to help prevent another one or modify the known risk factors for coronary artery disease,” Robert A. Kloner, M.D., Ph.D., director of cardiovascular research at Huntington Medical Research Institutes, tells SELF."

Recovered Data Casts Doubt On Whether Replacing Saturated Fat With Vegetable Oil Protects Against Heart Disease

By Stephanie Castillo, Medical Daily Americans have been told to eschew saturated fat for decades, in part because the American Heart Association has said consuming high amounts can increase cholesterol levels — and not the good kind. So in the late 60s, researchers conducted a trial to see if replacing saturated fats with vegetable oil rich in a healthier polyunsaturated fat, called linoleic acid, could lower levels of LDL “bad” cholesterol and reduce rates of coronary heart disease and death. All signs seemed to point to yes, but according to a new study published in BMJ, this hypothesis stands on shakier ground than people have been led to believe.

How researchers, Pasadena schools partnered to study traumatic brain injuries in teen athletes

By Jason Henry, San Gabriel Valley Tribune Meshia Paton wasn’t sure about her 15-year-old son playing football at Pasadena High School. At that age, the other players hit pretty hard, she told him. But now she has a little more peace of mind if her son gets hurt — she got a full scan of his brain and his heart from a program offered for free through a partnership between Pasadena Unified School District and the Huntington Medical Research Institutes. It provides something to compare against in the event that her son, De’Shawn, is injured, and it didn’t cost her anything but time, she said.

8 Things You Need To Know About Inflammation And Anti-Inflammatory Diets 2016 Mar 24 4:22 PM Wellness By Rachel Jacoby Zoldan Read the original published feature at: http://www.self.com/wellness/2016/03/8-things-you-need-to-know-about-inflammation-and-anti-inflammatory-diets/ We break down one of the biggest, vaguest buzzwords in health and wellness—so you can actually understand what everyone's always talking about. Your body can do all kinds of amazing things, including protect itself. And that’s exactly what inflammation is: one part of the complex, biological response of bodily tissues to a variety of what the body deems “harmful” stimuli, including pathogens, damaged cells or irritants. However, in recent years inflammation’s gotten a bad rap. It’s been implicated in myriad ailments, from heart attacks to cancer, Alzheimer’s to mood disorders. A proliferation of anti-inflammatory diets have made their way onto the health scene, and various clinical studies have cited concern when an inflammatory response gets out of control. So which is it—friend or foe? Here’s everything you need to know before you start freaking out over inflammation.

1. Sometimes inflammation can be a really good thing for your body—in fact, it’s a fundamental function of your immune system.

“Think about what happens when you get a splinter. Some bacteria can get in there, it may start to feel a little bit hot, get red, and could swell up,” Andrea Loewendorf, Ph.D., an immunology research scientist at Huntington Medical Research Institutes in Pasadena, California, tells SELF. That’s an example of a great inflammatory response—your body is literally defending itself by sending immune cells to kill the bacteria or pathogenic invader. Specifically, this is what’s known as an acute inflammatory response, signs of which include redness, heat, pain, swelling, and loss of function. However, because the response is acute, it should only last for a few hours max while your body is working to repair itself. An extreme version of acute inflammation? Swelling around the brain after injury. Of course, not a great thought, but again, it’s a clear example of how inflammation is a bodily response designed to protect—not harm—our own bodies.

2. Our bodies are always in some kind of inflammatory state.

“Inflammation is a part of our immune system,” says Loewendorf. “It’s the immune system at work.” Things like open wounds healing, swelling around broken bones and even a fever when you’ve caught a virus are all examples of the inflammatory response at its finest, making sure to repair what needs fixing, she tells SELF. Nutritionist and holistic health coach Amanda Goldfarb, R.D., of Pawley’s Island, SC, concurs. “Despite the buzz around the ‘anti-inflammatory diets,’ you can’t kill the bodily function entirely—your body is always going through some sort of inflammation,” Goldfarb tells SELF.

3. But if our immune systems start to overreact, that’s when problems could kick in.

“The first sign of your immune system going above and beyond is allergies,” says Loewendorf. Let’s say you’re allergic to peanuts: If you eat one, your immune system overreacts causing an allergic reaction, which, depending on the sensitivity of your allergy, could even kill you, she notes. “Diseases like lupus or multiple sclerosis, both autoimmune conditions, are when the immune system is unable to differentiate between what’s dangerous and what’s not,” Loewendorf tells SELF. “When you have one of these diseases, your immune system doesn’t understand that ‘This is myself, this is me.’” While the mechanism may be clear, there are no cures for the majority of autoimmune diseases, just palliative medications to keep a condition in check. “With type I diabetes, which is an autoimmune disease, the body turns on and destroys insulin-producing cells,” says Loewendorf. “You can’t make insulin anymore. You have to inject yourself daily.” Rheumatoid arthritis is another example of an autoimmune disease, which causes painful swelling in the lining of the joints. The chronic inflammation can also affect other parts of the body, such as the lungs, nerves, and blood vessels.

4. When you hear people talking about the dangers of inflammation, what they’re really talking about is chronic inflammation.

As opposed to acute inflammation—a response to injury or infection—chronic inflammation doesn’t have a positive role to play. It can exist, as with the conditions described above, in a constant low-level state, doing nothing helpful and possibly putting many body systems at risk. For example, if there are inflammatory cells just hanging out in your blood stream all the time, they can damage your arteries. This leads to a buildup of plaque in the artery wall, which increases the risk of heart attack and stroke. The extent of the effects of chronic inflammation is not very well understood, but it’s a hot topic in medical science as well as in the mainstream media and wellness circles.

5. Interestingly, obesity is also considered to be a state of chronic inflammation.

There is a theory that obesity is a kind of physical manifestation of inflammation. Caroline Apovian, M.D., director of the Nutrition and Weight Management Center at Boston Medical Center and professor of medicine and pediatrics at the Boston University School of Medicine, is one of the proponents of this theory. “We realized a while back that obesity is a state of chronic inflammation,” Apovian tells SELF. She describes a cascade of bodily responses, starting with the accumulation of fat, which leads to the release of pro-inflammatory molecules and an influx of immune cells, especially macrophages, which clean up dead cells and debris. “Then, the inflammation leaks into the blood because immune cells secrete what we call cytokines into the blood, which can lead to dangerous inflammation in other tissues, like the heart and pancreas,” she says. Inflammation, in this case, is almost like a domino effect: The more fat tissues you develop, the more inflammatory responses you’ll have and more organs could be affected, Apovian adds.

6. There are multiple ways to control inflammation (to a point).

Got a swollen ankle or a fever? These are both acute examples of inflammation that can be treated with OTC anti-inflammatories like Advil and Aleve, Loewendorf tells SELF. Ice works well to constrict blood vessels and reduce painful swelling. Acute inflammation has a purpose—and a job to do—so it’s not inherently a bad thing you want to stop, except that it can be painful, and that’s what the pain meds and ice are for. Autoimmune disorders, unfortunately, don’t serve any greater purpose, and worse, doctors are for the most part stumped about how to stop them. But each has its own treatment regimen to control symptoms.

7. What you eat can have an effect on systemic inflammation in the body—but there isn’t a scientific consensus on “anti-inflammatory” diets.

Goldfarb says that processed carbs, anything with trans fats, red meats, and anything with lots of sugar is inflammation-inducing and could lead to more chronic issues. Therefore she urges the importance of cutting these out of your diet. (And it looks like about half of us need to heed that warning, big time: A new study published in BMJ found that over half of Americans subsist on a diet of ultra-processed foods. Yikes!) Ask Apovian about the anti-inflammatory diet and she’ll tell you “it’s just jargon.” Similarly, Goldfarb says it’s not about a specific diet plan when trying to reduce inflammation using your eating habits—it’s more about cleaning things up. “I would never tell a client, ‘I’m putting you on an anti-inflammatory diet,’” Goldfarb tells SELF, “I’d say, ‘Let’s see what we can change,’ instead.” However, if you look to Drs. Nicholas Perricone and Frank Lipman, who have both made waves in the health world recently, you’ll see they both have their own versions of anti-inflammatory diets. The idea is basically to cut out those same foods Goldfarb recommends against, while focusing on inflammation-reducing ones, such as foods rich in omega-3 fatty acids (hello, salmon), fruits and veggies, which are packed with antioxidants (let the battle over nightshade vegetables commence; some experts suggest avoiding their potentially inflammatory effects, while others tout their anti-inflammatory prowess), and a liberal use of spices. Not only do these diets purport to make weight loss easier, but they also claim to slow the aging process and prevent disease. Goldfarb can’t argue with that advice, even if she wouldn’t use the term “anti-inflammatory.” She would similarly recommend a diet rich in whole, clean foods—incorporating the use of as much fresh food as possible. “You’re going to feel better, and you’re going to lose weight. It’s a win-win,” she tells SELF.

8. If you worry about inflammation, eating a good diet and adopting good lifestyle habits is a good start.

Whatever you call it, eating antioxidant-rich foods, plenty of omega-3s, and staying away from sugar and trans fats is a pretty inarguable strategy for good health and can help limit unnecessary inflammation that could be caused by your diet. Maintaining a healthy body weight will also keep you from experiencing undue systemic inflammation, as will not smoking and not overindulging in alcohol.

Shereif Rezkalla, MD, FACP, FACC, Rachel Stankowski, PhD, and Robert A. Kloner, MD, PhD, FACC, Plants of the Cannabis species, commonly known as marijuana, contain numerous psychoactive components, including the primary psychoactive compound D-9-tetrahyrdocannabinol (THC).1 The World Health Organization (WHO) describes cannabis as the most widely used, cultivated, and trafficked illicit drug in the world, with an estimated 147 million people using the drug annually.2 Consistent with worldwide reports, the Substance Abuse and Mental Health Services Administration estimated nearly 20 million active marijuana users in the United States in 2013, making it the most widely used illicit drug in the nation.3 Evidence of therapeutic potential for marijuana and its components has been suggested for a number of medical conditions, including cachexia, cancer, glaucoma, HIV/AIDS, muscle spasm, seizures, severe nausea, severe or chronic pain, and sleep disorders,1 though lack of scientific evidence regarding safety and efficacy has prohibited endorsement by the US Food and Drug Administration for any therapeutic use.

Before you go out and swap your breath mints for an aspirin, it is important to know that the recent recommendation by the U.S. Preventive Services Task Force (USPSTF) that has been making the rounds abuzz isn't as simple as the headlines make it seem. Dr. Robert A. Kloner, director of cardiovascular research and vice president of translation at the Huntington Medical Research Institutes was quoted as saying, "It's very important to point out [the USPSTF is] not saying everyone should be on aspirin ...They're saying people ages 50 to 59, who have an increased risk of heart disease, should take a daily low-dose aspirin. So you're looking at a certain age group, first of all." Taking Aspirin, even in low doses may not be suitable for everyone, and in some cases in can do more harm than good. "Some people are allergic to it, and… some people are prone to bleed," Dr. Kloner explains. "And so if you have a history of bleeding ulcers or other bleeding problems, then you are probably not going to be a candidate for aspirin." For more information about Dr. Robert A. Kloner, view his bio, or to read the complete story, please visit the link below: http://www.drozthegoodlife.com/health-articles/health-conditions/news/a510/daily-aspirin-uspstf-recommendation-not-universal/ All Credit: Amy Capetta, DR.

Awash in frozen packs of umbilical cord blood, StemCyte Inc. needed to move. That’s because of increasing demand from parents to store their babies’ stem cell-rich cord blood for a range of future therapies, some of which are only now being studied and developed. Now, having taken root earlier this year in a 48,000-square-foot headquarters building in Baldwin Park, the company has room for more than 150 of the massive tanks it needs three times the capacity of its old home – each holding more than a thousand frozen packs of cord blood. Blood is big business, and demand for cord blood in particular has been growing.

Playing tackle football before the age of 12 may be linked to brain changes seen in pro football players who developed memory and thinking problems later in life, new research suggests. "It makes sense that children, whose brains are rapidly developing, should not be hitting their heads over and over again," said lead author Julie Stamm, who conducted the study as part of her doctoral dissertation at Boston University's Center for the Study of Traumatic Encephalopathy.

Dr. Myron Tong of the Huntington Medical Research Institutes was recently interviewed regarding the hidden dangers of taking common painkillers in a story reported on Fox News' website.  The story which was published on August 15th, 2015 points out that: "Nonsteroidal anti-inflammatory drugs, commonly referred to as NSAIDs, are used to alleviate fever symptoms and reduce pain. Most people who take over-the-counter NSAIDs use them to ease the occasional headache or muscle pain. But they also provide quick relief for an estimated 52 million Americans— mostly older adults— with arthritis. In these cases, prescription-strength NSAIDs drastically improve quality of life with few noticeable side effects." Dr. Tong was quoted as saying, "These are some of the most popular drugs in the world ... And as the American population ages, usage will probably increase too." According to the report, research shows that the regular use of the drugs increases the long-term risk of "heart attack, stroke, liver damage and ulcers."

Dr. Howard Kaufman, director of HMRI’s Colorectal Research Program, is one of the initial 16 doctors across the nation approved to perform the new InterStim® bowel control therapy, offered by Medtronic, Inc., of Minneapolis, MN. Dr. Kaufman was a co-investigator in a multinational multicenter clinical study into whether the InterStim Therapy for urinary incontinence, for which Medtronic won FDA approval in 1997, could be successfully applied to bowel incontinence. “The study in which Dr. Kaufman participated to evaluate the Medtronic InterStim system as a remedy for bowel incontinence fits well with the history of HMRI’s Neural Engineering Program for developing and evaluating clinical applications of nerve stimulations,” said Dr. Douglas McCreery, Neural Engineering director. The HMRI Neural Engineering researchers have a long history of developing electrodes for activating nerves. The Huntington Helix array was licensed to Cyberonics, Inc. and subsequently has been implanted into more than 40,000 persons with epilepsy and with depression. Other version of our nerve electrodes have been evaluated by clinicians at the Cleveland Clinic for treating swallowing difficulties following cerebral stroke and at Washington University in St. Louis for treating urge incontinence.   This latest InterStim study’s success earned FDA approval in March. Chronic involuntary loss of bowel control is a humiliating, life-changing condition. According to a National Institutes of Health (NIH)-funded study, more than 18 million Americans have fecal incontinence. Among older persons, the infirmity is the single most frequent factor for admittance to nursing homes because families have difficulty dealing with its demands. Caused by a variety of factors, it is most common among adults, predominately women who experience nerve and muscular trauma in the anus, rectum, and pelvic floor during childbirth. Eileen Brophy Williams was Dr. Kaufman’s first patient to participate in the clinical study. The former Newport Beach resident’s bowel incontinence resulted from an unsuccessful sphincteroplasty repair of an episiotomy following the birth of her first child 13 years ago. Her colorectal surgeon, Dr. Babak Rad, heard of the clinical study and referred her to Dr. Kaufman. She thought her incontinence was due to digestion problems because she was a new mother nervous about her child or possibly related to an old back injury. She simply had no feeling or sensation when she had incontinent episodes that occurred almost every day. Her life was severely limited to her household, and she wasn’t able to participate in her children’s school projects and so much more. Brophy Williams was a perfect candidate for the clinical trial because she had gone through various other treatment options. Dr. Kaufman explained those therapies included bowel habit modification through diet (increasing fiber, prescribing anti-diarrheal medications, etc.), sphincter muscle surgery, as well as biofeedback and physical therapy. InterStim Therapy is the only bowel control treatment option that allows patients and physicians to determine probable success of the therapy through a test stimulation procedure prior to committing to long-term therapy. Brophy Williams went through InterStim’s two-step outpatient implant process in March 2005. During the first visit, an electrode connects sacral nerves to an external test stimulator that can be adjusted for the correct amperage to stimulate nerves. “Patients will then walk around with the InterStim on a belt that’s programmed with the help of a Medtronic technician,” Dr. Kaufman explained. “If they pass the test of a reduction of incontinence of more than 50 percent for two weeks, they will qualify for a permanent implant.” Brophy Williams said that during those two weeks, she experienced the sensation for a bowel movement that she hadn’t experienced in years. She became a candidate for permanent implant. The InterStim Therapy uses an implantable system consisting of a thin wire lead and a neurostimulator, or pacemaker-like device about the size of a quarter, to stimulate the sacral nerve to control bowel function. The neurostimulator is implanted on the upper part of the buttock above the pelvis. “I was involved with the industry and thought this would be a technology to offer patients who had been unsuccessful with available therapies,” Dr. Kaufman said. “I was fortunate to have the patient population and the relationship already with Medtronic and other companies so we could stratify patients based on their anatomy and physiology.” “We implanted the device in 120 patients who met the inclusion criteria with various degrees of fecal incontinence,” Dr. Kaufman said. The study ran from 2002-2008, and “showed that at 12 months, 83 percent achieved ‘therapeutic’ success (with 41 percent of those subjects reaching 100 percent continence). While our paper reported on sustained success through two years, most patients have had continued success through their continued length of follow-up.” Additionally incontinent episodes decreased from a mean of 9.4 per week to 1.9/week at 12 months and 2.9/week at two years. “When I had this surgery within two weeks time, I was able to get involved with my kids in school,” Brophy Williams said. “It gave me back my life. I had stopped myself from having a life.” “There are women who are going through this who don’t even know they have this. I had no idea I was as injured as I was. I was told there wasn’t any help for me.” “Dr. Rad and Dr. Kaufman never gave up on me,” she recalled. “I owe them my life and my life with my kids and family.” Now, Dr. Kaufman is the first physician authorized to perform the InterStim implant for patients in the Southwest, including Southern California, Nevada, Arizona and New Mexico. After he has completed 20 implants, Dr. Kaufman will train other colorectal surgeons in the two-step, out-patient procedure. In an unrelated project funded by the National Institutes of Health, HMRI's Neural Engineering Program researchers have been working to develop a neuroprosthetic device to artificially control urination for spinal cord injured patients. HMRI NEP scientists are also studying mechanisms of stroke-induced overactive bladder and a possible treatment by intraspinal microstimulation.

The Magnetic Resonance Laboratory is offering complimentary cardiac and brain screening exams for student athletes of the Pasadena Unified School District (PUSD). We are currently working with Ann Rector, PUSD Health Coordinator, to recruit students who are actively involved in sports. These prevention-oriented MR scans will be able to detect life-threatening cardiac anomalies that can cause sudden cardiac death, as well as assess and monitor brain injuries, resulting from sports-related incidents, which may cause long-term physical, neurocognitive, and behavioral deficits. Brain and cardiac magnetic resonance imaging exams are non-invasive, clinical routine procedures that allow for visualization of anatomy and functional assessments. The cardiac exam can detect congenital heart conditions and cardiomyopathies, which can prove to be life-threatening to those who physically exert themselves through sports. Students enrolled in the cardiac program will only need to have one cardiac screening exam performed, while the brain exam will be conducted once at the beginning of the season and subsequent exams will be performed if a student suffers any injuries during the season to evaluate changes due to trauma. These prevention-oriented research initiatives are of particular importance to the students of PUSD, who are largely underserved with 67% of students identified as low-income; and thus likely to have minimal access to sufficient health care, including specialized procedures such as magnetic resonance imaging. We are currently recruiting student athletes between the ages of 10-18 for either or both exams. For more information or to participate, please contact Darlene Royal at 626-397-5840 or email us at MagRes.HMRI@gmail.com.

PASADENA, CA -  A groundbreaking study on Alzheimer’s Disease, authored by HMRI Senior Biochemist Dr. Alfred Fonteh, and his colleagues from HMRI’s Molecular Neurology Program, has just been published in PLOS ONE, a leading scientific peer-reviewed journal. Entitled Human Cerebrospinal Fluid Fatty Acid Levels Differ between Supernatant Fluid and Brain-Derived Nanoparticle Fractions, and Are Altered in Alzheimer’s Disease, the study shows that the cerebrospinal fluid of patients with Alzheimer’s Disease may contain diagnostic information before they have memory loss. The spinal fluid analysis also points to possible new avenues of therapy.  The 3-year study found significant differences in fatty acids in cerebrospinal fluid – the fluid that bathes the brain and spinal cord – between Alzheimer’s and cognitively healthy patients.  In particular, Omega-3 fatty acid levels were found to be considerably reduced in Alzheimer’s patients. “We measured a vast number of lipid compounds in the cerebrospinal fluid and found a lot of changes, especially in Omega-3 fatty acids and also in the mono-unsaturated fatty acids,” said Dr. Alfred Fonteh, HMRI Senior Biochemist, and the lead researcher on the study.  “These (Omega-3’s) are the kind of fatty acids that you often find in a Mediterranean diet.” Dr. Fonteh noted that in earlier studies people in countries with high-fish diets – foods particularly rich in Omega-3 fatty acids  – were found to have better memory function and tend not to have as high an incidence of Alzheimer’s disease.  These data formed part of the hypothesis that led to his study.  In addition, it was known from earlier studies of Alzheimer’s disease that the brain – which contains abundant fatty acids – shrinks considerably in Alzheimer’s patients. This was the first study of its kind to be conducted on live human subjects.  “For a long time people have done animal studies that found that if you provide a certain amount of Omega-3 fatty acids to rats, it prevents memory loss,” Dr. Fonteh continued.  “But no one has ever studied humans to discover levels of Omega-3 fatty acids in the brain, or whether they’re actually depleted or have any significance in disease.”  By looking in cerebrospinal fluid, the researchers have a more direct read-out of changes in the brain, rather than looking in blood where molecular changes originating from the brain are mixed together with changes from all the other organs. The findings of the study raise new questions, to explore new treatment options.  The changes in fatty acids within cerebrospinal fluid could be used as markers to characterize the stage of Alzheimer’s disease and perhaps to monitor response to therapies.  Intriguingly, looking at restoration of fatty acids may be an approach to therapy, and the HMRI group will be addressing the results of this study with further research in the same patients, new study participants, in parallel with laboratory studies.

ALFRED FONTEH Dr. Alfred Fonteh holds a Ph.D. in biochemistry from the University of London, and completed postdoctoral studies at Johns Hopkins University Asthma and Allergy Center.  Prior to coming to HMRI, he held positions of Research Associate, Instructor of Medicine and Assistant Professor at Wake Forest University School of Medicine.  Dr. Fonteh has been with HMRI for 13 years, and now holds the position of Senior Biochemist.  His research path focuses on lipid signaling pathways to discover therapeutic targets of neurological disorders, including migraine.

New Equipment Enhances Critical Tissue Engineering Research

As our world becomes a faster-paced environment, life sciences have turned to automation to reduce costs and create more efficient operations.  Thanks to a grant from the Roy E. Thomas Foundation, researchers in the HMRI Tissue Engineering laboratory have recently acquired two new instruments that will allow them to streamline workflow through automation and spend more time on the discovery process in their search for new anti-cancer drugs. With the new Biomek 4000 Laboratory Automation Workstation, our Tissue Engineering program has the ability to increase production of tumor histoids – living human mini-tumors – used in testing new anti-cancer drugs.  Producing the large number of tumor histoids required for drug testing would be virtually impossible without robotic fluid handling offered by the Biomek 4000.  Much of the exorbitant cost of developing new anti-cancer drugs is attributed to the use of unreliable and inefficient test systems during screening of potential new drugs and can cost upwards of $1 billion to bring one new drug to market. The grant from the Roy E. Thomas Foundation also enabled the purchase of a second essential piece of equipment, the Synergy H1 Hybrid Multi-Mode Microplate Reader.  Placed next to the Biomek 4000 robotic system, this temperature-controlled programmable plate reader is used for spectrophotometric analysis of tumor histoids within their droplets.  Both pieces of equipment are housed within a laminar flow tissue culture hood, a requirement for maintaining the integrity of sterile cultures. “We are absolutely delighted, to say nothing of relieved and grateful, to have the important new equipment which will allow us to advance to a new phase of our research,” said Dr. Marylou Ingram, senior research scientist with the Tissue Engineering & In Vitro Systems program. “The grant from the Roy E. Thomas Foundation could not have been more timely or important to our research.”

“Thank you so much for coming to our science fair and teaching us about the human brain.  It looked really strange but was so cool!” “Thank you for inspiring [us] with science.  The fact I found most interesting is that neurologists do not know the causes of brain diseases.  I will look into becoming a neurologist.” “I learned so much from you about our brain.  My dad was amazed that I knew so much.” These are but a few of the many accolades expressed in “thank you” letters received by Dr. Michael Harrington, HMRI’s director of Molecular Neurology, following his presentation at a reverse science fair at Holy Redeeemer Middle School in Montrose.  Harrington was one of a number of physicians, researchers and engineers invited to participate in this annual event to give 7^th and 8^th graders an opportunity to understand science and medicine “up close and personal.” Beth Cohen, Holy Redeemer’s science teacher, acknowledged that Harrington’s presentation regarding the brain is the most popular which is why she invites him back every year.  “He truly knows how to inspire these kids and pique their curiosity,” she noted.  “His style is very real rather than sounding like a text book.”  The classroom presentation included viewing a real human brain followed by an explanation of the function of the brain and the mystery of brain diseases such as Alzheimer’s, Parkinson’s and migraine. “As a researcher, I feel we have a moral and social responsibility to share information with our youth through science education,” noted Harrington.  “I thoroughly enjoy this annual opportunity to interact with our young people.”

For 20 years, Paula Welch-Forrest led a reclusive lifestyle complete with clinical depression, low energy, a lack of self-esteem and virtually no zest for life.  In 2012, Dr. Howard Kaufman, colorectal surgeon and HMRI researcher, changed all of that. Suffering from numerous colorectal problems and unable to get a proper diagnosis or successful treatment, Forrest was eventually referred to Kaufman. “By the time I met Dr. Kaufman, I had already been told I had the colon of an 80-year-old,” said 49-year-old Forrest.  “Dr. Kaufman was so kind and asked me questions that no other physician had bothered to ask.  He also listened carefully to what I had to say in order to put all of the pieces of the puzzle together.”  Forrest sensed right away that she finally had met the right physician whose extensive research and experience made him one of the top experts in his field. With a diagnosis of colonic inertia, a condition that occurs when muscles or nerves in the colon fail to function effectively, Kaufman performed a laparoscopic total abdominal colectomy.  Sometimes known as an ileorectal anastomosis, the surgery involves removal of the large intestine from the ileum (lowest part of the small intestine) to the rectum.  The end of the small intestine is then attached to the rectum. “Ms. Forrest was a wonderful and cooperative patient who was anxious to resolve her long-standing medical issues. I’m pleased that she recovered so well from the procedure and is moving forward with her life,” stated Kaufman. Since her surgical procedure, Forrest’s lifestyle has changed considerably.  She has become an active, social person who no longer hides out from the world.  Her family and friends barely recognize the new persona but are delighted.  “My husband calls me his ‘social butterfly’ now and tries to keep up with my schedule,” commented Forrest.  “I was too embarrassed to speak out about my medical problems before, but now I want to ‘shout it from the rooftops’ so others like me have hope.” In addition to a private practice and serving as medical director for Huntington Hospital’s Cancer Center, Kaufman is director of the Colorectal Research program at HMRI where he passionately pursues new technologies in his field.  He was one of the early pioneers of minimally invasive surgery for Crohn’s disease and was the first surgeon on the west coast to perform colon resections laparoscopically through a tiny single incision. “I cannot sing the praises of Dr. Kaufman enough,” said Forrest.  “Every time I receive a compliment regarding my renewed health, I tell them that Dr. Kaufman literally saved my life.  I’m asking everyone to show their appreciation by sending a donation to HMRI for the Colorectal Research Fund.  I’m proud to be able to honor Dr. Kaufman in this way so others can experience the same successful outcome.”

HMRI has just purchased a scientific instrument vital to its research—a Zeiss LSM 510 META confocal microscope. Half the funds for the purchase were provided by the Altadena Guild of Huntington Hospital, a major funding partner of HMRI for over 60 years. The microscope greatly enhances the ability of HMRI neural engineers and neurologists to conduct detailed in-house research. “We received a great deal of assistance from the Altadena Guild to purchase this instrument, for which we are very grateful,” said Dr. Douglas McCreery, director of HMRI’s Neural Engineering program. “With the confocal microscope, we now have the ability to visually reach down into tissue and obtain a three-dimensional reconstruction of all of the different cell types. Doing this same work with a conventional microscope is extremely laborious and time-consuming, which is what we had to do prior to the confocal microscope.” A confocal microscope allows examination of a specimen in such a way that extremely high detail is obtained. Specific molecules can be isolated and examined by placing fluorescent dyes within antibodies which attach themselves to the molecules. A laser is used to cause the dyes to “light up” and be seen within the microscope. Because the microscope can also reach downward within a specimen, specific detail can be viewed which cannot be obtained with a conventional light microscope. “For a conventional microscope, specimens must be cut into thin sections,” explained Dr. Martin Han, biomedical engineer and staff scientist in HMRI's Neural Engineering program. “Whenever you cut tissue sections, you sacrifice a little bit of detail of the top and bottom. When you can examine it all together in one specimen, you preserve much of the existing tissue as it is, instead of losing 5 to 10 percent of everything you cut.” The microscope has already been put to immediate use within HMRI.  In research dealing with neurological implants, it is being used to view the results of long-term implantation. “On a cellular level, we are studying the interaction between the brain and the device we put into the brain,” said Han. “Prior to having the confocal microscope, we did some work using a confocal microscope at Caltech. The advantage of our new microscope over others is that it is motorized. We would have to manually scan a large area which took a long time and was very expensive. Now, we can automate the moving of one area to the next. It saves a lot of time and reduces human error.” “Having the equipment here, I can actually turn it on, leave it on for 24 hours, and let it scan whatever it needs to scan for an indefinite period,”  added Haison Duong, HMRI Neural Engineering research associate  “That increases the workflow quite a bit. I can basically calibrate all the settings and let it work on its own.” Another area of research utilizing the microscope is that of migraine headaches. “I plan to use the confocal microscope to look at the fine cellular localization of particular molecules that are involved in a model of migraine that we're studying,” said Dr. Michael Harrington, director of HMRI's Molecular Neurology program. “The reason we need a confocal microscope is that if I have two different molecules in the same cell, and they're in different regions of the cell, there's no way a regular microscope will unequivocally let me know where things are. That’s why we need the confocal microscope: we need what we refer to as sub-cellular localization.” In addition to the microscope itself, an attached computer and software is utilized for three-dimensional renderings after observation. Such renderings make it possible to view specimens from multiple angles, and also “stitch” together different images to create one all-encompassing image. Due to the capability of bringing detailed research completely in-house, it is expected that the LSM 510 META confocal microscope will earn back its purchase price rather quickly. “It will pay for itself within a year, just based on what it costs us per hour to go to another facility,” noted Duong.

Neural Engineering researchers at Huntington Medical Research Institutes in Pasadena, California, have been chosen by the Defense Advanced Research Projects Agency (DARPA) to develop a better interface between the brain and prosthetic limbs. DARPA, the Department of Defense research and development office, has been faced with a continual challenge regarding prosthetics used by wounded war fighters returning from combat. Today’s best prosthetics have low functionality, and DARPA seeks to upgrade to models with greater dexterity and brain communication capability. That’s where researchers of HMRI’s Neural Engineering Department come in. They will determine why current brain interfaces to prosthetics fail over a relatively short time, usually a month or two. Once that has been determined, HMRI researchers hope to enable control of complex arm prosthetics by the brain to boost capability from 2 degrees of movement to 22 degrees, increasing elbow and wrist rotation and finger movements for greater facility in picking up objects, and keep that ability for years. In a recent clinical trial, “intracortical electrodes that could eventually be used for these complex robotic arms have shown to be unreliable even though they showed some promise,” said Dr. Martin Han, the primary investigator on the project, working with Dr. Douglas McCreery, director of HMRI’s Neural Engineering Program, and Dr. Victor Pikov. This project is a natural for HMRI’s Neural Engineering researchers. Established in 1970, the multi-disciplinary program’s goal is design, development and evaluation of implantable devices for functional electrical stimulation to replace impaired function of the nervous system. The HMRI program has internationally recognized expertise in evaluating the safety of the electrode-tissue interface, a major factor in the success of implantable neural prostheses such as those that could potentially be used by amputees. This is the first time the Neural Engineering Program has submitted a proposal to DARPA, and it’s not surprising HMRI won the contract. By incorporating four widely used electrode designs into a hybrid array, the Investigators propose to determine why the microelectrodes fail to record neuronal action potentials over long periods of time. Researchers have been trying to answer the question “Why do these devices fail?” “However, different researchers have used different surgical techniques, and different devices implanted into different brain regions," Han said. “Whenever these neurons fire, they tell these devices what to do. It’s very critical. When you lose that interface, you lose function,” he explained. “That interface” between neurons and prosthetic device is created when a microelectrode is implanted into the brain to record and decode its instructions to control the device. The microelectrode can be as thin as a single strand of hair and made of metal or metal-like silicon, though HMRI’s neural engineers have created thinner, more flexible polymer models. In this project, instead of stimulating neurons to fire, the microelectrodes “wait” for the neurons to transmit information that will drive a prosthetic arm in a certain way, for example, direction and velocity of movement. Some prosthetic arms are currently attached to muscle groups that govern movement. Implantable microelectrodes transmitting directly from neurons could offer users greater control and natural movement. Findings from this study could go beyond prosthetics to applications for other neurological disorders, including Parkinson’s disease and epilepsy, Han added. “This could be used for detecting epileptic seizures,” he explained. “Before a major onset of an epileptic seizure, there’s known to be some subtle brain activity that’s hard to detect with current technologies, but with these electrodes in the brain, they can detect the pending onset of a seizure before it happens.” This work is sponsored by the Defense Advanced Research Projects Agency (DARPA) Microsystems Technology Office (MTO), under the auspices of Dr. Jack W. Judy (jack.judy@darpa.mil) as part of the Reliable Neural Technology Program, through the Space and Naval Warfare Systems Command (SPAWAR) Systems Center (SSC) Pacific grant No. N66001-11-1-4010.

Dr. Howard Kaufman, director of HMRI’s Colorectal Research Program, is one of the initial 16 doctors across the nation approved to perform the new InterStim® bowel control therapy, offered by Medtronic, Inc., of Minneapolis, MN. Dr. Kaufman was a co-investigator in a multinational multicenter clinical study into whether the InterStim Therapy for urinary incontinence, for which Medtronic won FDA approval in 1997, could be successfully applied to bowel incontinence. “The study in which Dr. Kaufman participated to evaluate the Medtronic InterStim system as a remedy for bowel incontinence fits well with the history of HMRI’s Neural Engineering Program for developing and evaluating clinical applications of nerve stimulations,” said Dr. Douglas McCreery, Neural Engineering director. The HMRI Neural Engineering researchers have a long history of developing electrodes for activating nerves. The Huntington Helix array was licensed to Cyberonics, Inc. and subsequently has been implanted into more than 40,000 persons with epilepsy and with depression. Other version of our nerve electrodes have been evaluated by clinicians at the Cleveland Clinic for treating swallowing difficulties following cerebral stroke and at Washington University in St. Louis for treating urge incontinence. This latest InterStim study’s success earned FDA approval in March. Chronic involuntary loss of bowel control is a humiliating, life-changing condition. According to a National Institutes of Health (NIH)-funded study, more than 18 million Americans have fecal incontinence. Among older persons, the infirmity is the single most frequent factor for admittance to nursing homes because families have difficulty dealing with its demands. Caused by a variety of factors, it is most common among adults, predominately women who experience nerve and muscular trauma in the anus, rectum, and pelvic floor during childbirth. Eileen Brophy Williams was Dr. Kaufman’s first patient to participate in the clinical study. The former Newport Beach resident’s bowel incontinence resulted from an unsuccessful sphincteroplasty repair of an episiotomy following the birth of her first child 13 years ago. Her colorectal surgeon, Dr. Babak Rad, heard of the clinical study and referred her to Dr. Kaufman. She thought her incontinence was due to digestion problems because she was a new mother nervous about her child or possibly related to an old back injury. She simply had no feeling or sensation when she had incontinent episodes that occurred almost every day. Her life was severely limited to her household, and she wasn’t able to participate in her children’s school projects and so much more. Brophy Williams was a perfect candidate for the clinical trial because she had gone through various other treatment options. Dr. Kaufman explained those therapies included bowel habit modification through diet (increasing fiber, prescribing anti-diarrheal medications, etc.), sphincter muscle surgery, as well as biofeedback and physical therapy. InterStim Therapy is the only bowel control treatment option that allows patients and physicians to determine probable success of the therapy through a test stimulation procedure prior to committing to long-term therapy. Brophy Williams went through InterStim’s two-step outpatient implant process in March 2005. During the first visit, an electrode connects sacral nerves to an external test stimulator that can be adjusted for the correct amperage to stimulate nerves. “Patients will then walk around with the InterStim on a belt that’s programmed with the help of a Medtronic technician,” Dr. Kaufman explained. “If they pass the test of a reduction of incontinence of more than 50 percent for two weeks, they will qualify for a permanent implant.” Brophy Williams said that during those two weeks, she experienced the sensation for a bowel movement that she hadn’t experienced in years. She became a candidate for permanent implant. The InterStim Therapy uses an implantable system consisting of a thin wire lead and a neurostimulator, or pacemaker-like device about the size of a quarter, to stimulate the sacral nerve to control bowel function. The neurostimulator is implanted on the upper part of the buttock above the pelvis. “I was involved with the industry and thought this would be a technology to offer patients who had been unsuccessful with available therapies,” Dr. Kaufman said. “I was fortunate to have the patient population and the relationship already with Medtronic and other companies so we could stratify patients based on their anatomy and physiology.” “We implanted the device in 120 patients who met the inclusion criteria with various degrees of fecal incontinence,” Dr. Kaufman said. The study ran from 2002-2008, and “showed that at 12 months, 83 percent achieved ‘therapeutic’ success (with 41 percent of those subjects reaching 100 percent continence). While our paper reported on sustained success through two years, most patients have had continued success through their continued length of follow-up.” Additionally incontinent episodes decreased from a mean of 9.4 per week to 1.9/week at 12 months and 2.9/week at two years. “When I had this surgery within two weeks time, I was able to get involved with my kids in school,” Brophy Williams said. “It gave me back my life. I had stopped myself from having a life.” “There are women who are going through this who don’t even know they have this. I had no idea I was as injured as I was. I was told there wasn’t any help for me.” “Dr. Rad and Dr. Kaufman never gave up on me,” she recalled. “I owe them my life and my life with my kids and family.” Now, Dr. Kaufman is the first physician authorized to perform the InterStim implant for patients in the Southwest, including Southern California, Nevada, Arizona and New Mexico. After he has completed 20 implants, Dr. Kaufman will train other colorectal surgeons in the two-step, out-patient procedure. In an unrelated project funded by the National Institutes of Health, HMRI's Neural Engineering Program researchers have been working to develop a neuroprosthetic device to artificially control urination for spinal cord injured patients. HMRI NEP scientists are also studying mechanisms of stroke-induced overactive bladder and a possible treatment by intraspinal microstimulation.

The National Institutes of Health has awarded a four-year $1.4 million grant for migraine headache research to the Huntington Medical Research Institutes' Molecular Neurology Laboratory, directed by Michael Harrington, M.B., ChB., FRCP. HMRI scientists have recruited volunteer study participants from the San Gabriel Valley for research aimed at understanding the biochemistry of migraine. They measure the chemical composition of spinal fluid and blood, using powerful new mass spectrometry instruments combined with human genome information, to identify thousands of molecules in each sample. It is estimated that 30 million Americans suffer from migraine. Sufferers are exceptionally sick during migraine attacks, with pain affecting the muscles of the back of the head and neck. The HMRI scientists have identified components that change during attacks, between attacks, and what differs between migraine sufferers and those not troubled by headaches. Early results have revealed changes in molecules involved in many brain processes, including oxidation, blood vessel reactivity, pain and sleep. Dr. Harrington hopes to learn whether these chemical changes in the brain affect a predisposition to migraine, and so lead to better intervention and personalized treatment for individual sufferers. The project also receives funding from the Norris, Glide and Hezlep Family foundations, and from Thermo Finnigan, a medical technologies company in Palo Alto.

The National Institutes of Health awarded an $800,000 three-year research grant to Victor Pikov, Ph.D., of Huntington Medical Research Institutes' Neural Engineering Department. Dr. Pikov is studying the problem of stroke-related incontinence. His project, "Functional Microstimulation of the Lumbosacral Spinal Cord," explores using electrical stimulation to activate neurons in the spinal cord to restore bladder control following stroke. Pikov proposes using low-frequency electrical stimulation to create a stroke-like incontinence. The "virtual" stroke will inhibit the ability of lumbosacral spinal cord nerves to control the bladder. "Electrical stimulation in the spinal cord to restore voiding is a new area of research," says Dr. Pikov. "Only two other labs in the world are doing what we do at HMRI, but we have the advantage. We're using arrays of electrodes, rather than individual electrodes." For the past 30 years, HMRI's Neural Engineering program has been at the forefront of neural prosthesis research to produce safe, effective microstimulation to control the nervous system. In this case the implant, when activated, will produce symptoms of incontinence by applying repetitive electrical stimulation directly to the individual bladder neurons of the spinal cord. Pikov's simulation of incontinence is repeatable and reversible, and done without lesions or injury. The hoped-for result would be the development of an implantable array of electrodes controlling bladder function without any further need for invasive surgery or drug treatment. Stroke is the third leading cause of death in the United States and is the main cause of long-term disability among adults. Many people develop bladder dysfunction soon after suffering a stroke. A likely explanation is that a stroke reduces the brain's ability to inhibit the activity of spinal cord nerves involved in bladder contraction, resulting in incontinence. Currently, routine management of bladder dysfunction after stroke includes catheterization and drug treatment. Both have a significant risk of side effects such as urinary tract infections and urinary retention. Victor Pikov, Ph.D. was awarded the HMRI-Caltech Boswell Fellowship in 2000. The Boswell Fellowship, endowed by the James G. Boswell Foundation, supports postdoctoral scientists in joint research at Caltech and HMRI. He brings a background in neuroanatomy, immunohistochemisty and bladder physiology to the Neural Engineering laboratory. Born in Ukraine, he studied physiology at Kiev State University, received a B.A. cum laude in Biopsychology at Vassar College. He received his Ph.D. in Cell Biology from Georgetown University.

Their efforts have the potential to substantially improve the future quality of life for stroke patients.

One of the most distressing and challenging forms of neural injury is stroke. Also commonly called "brain attack," stroke affects the nervous system - one of the most important systems of the body, yet also the most vulnerable to injury and possessing the least capacity for recovery from the injury. Stroke is the third leading medical cause of death in the USA, the main cause of long-term disability among adults, and costs more than $70 billion annually in health care. About 30% of stroke victims are permanently disabled with a variety of severe impairments, including memory loss, vision, speech, motor control, voiding and sexual dysfunction. Intervention, prevention and rehabilitation methods to date have been insufficient to substantially reduce the number of strokes and alleviate their permanent side effects. Recently, Panya Steve Manoonkitiwongsa, Ph.D., of HMRI's Neural Engineering Laboratory described the nature of stroke, its complications and various treatments. He and his research colleagues are focusing on developing safe and effective therapeutic methods that would significantly improve existing forms of stroke recovery. Stroke injury can be broadly viewed as two types: hemorrhagic and ischemic. Both involve lack of oxygen to the brain. Hemorrhagic stroke occurs when blood vessels rupture and the blood oozes out of the vasculature (the blood vessels), causing the brain areas that normally receive blood from those hemorrhaged vessels - with the vital oxygen and nutrients they carry - to suffocate. Lack of blood (oxygen) to brain cells for just four minutes or less can permanently damage the cells. Hemorrhage further complicates the disease by pooling blood in the brain. Ischemic stroke, on the other hand, occurs when something in the blood vessel blocks the flow of blood; consequently, the blood stops flowing or its flow through the vessel is diminished. This leads to suffocation of the brain and damage to the brain cells. Most of the stroke incidences in the USA are ischemic strokes. Thus, most of the studies conducted in stroke research have addressed the biological problems and clinical treatments of ischemic stroke.

Current Treatment Choices

According to Dr. Manoon, the best intervention methods currently available "serve merely to restore blood flow and/or reduce the probability of further stroke injuries. Physical therapy commonly constitutes the rehabilitation process for the afflicted patient." Common non-invasive (that is, non-surgical) treatments for stroke include administering a variety of drugs to achieve several objectives:

• thrombolysis - opens up the blood vessels that have been blocked
• anticoagulation - thins the blood and reduces the probability of more blockage of the blood vessel
• antihypertension - reduces blood pressure to avoid hemorrhage of the weakened blood vessels, or injury to the brain.
• antiplatelet - reduces inflammation-related events so as to minimize the probability of further blockage of the blood vessel.

Thrombolysis is the treatment that is administered immediately to a patient when brought to the hospital or clinic to open up blocked blood vessels and restore blood flow to the brain. It involves infusion of tissue plasminogen activator (tPA) and is currently the only Food & Drug Administration (FDA)-approved procedure. This therapy is very limited in its application and effectiveness. It must be given within three hours from the onset of stroke, or hemorrhage may occur. The patient must not be on medications that could weaken the blood vessels, nor have any disease or abnormalities that could cause the weakening of the blood vessels. This treatment merely serves to restore blood flow but not to protect the brain cells (neurons) from injury and death. Furthermore, administration of tPA to the patient, in itself, could damage the neurons.

Improving the Odds

Unless the neurons that are damaged in stroke are preserved or protected from death, recovery can take a long time, if the patient recovers at all. Thus, stroke specialists agree that neuroprotection - that is, administering substances that would help preserve or protect the neurons - should be included with the tPA thrombolytic treatment. These would not only protect the neurons and reduce brain injury caused by the ischemic stroke, but also compensate for the adverse effects of tPA on the neurons. Several researchers worldwide are also proposing angiogenesis: treating stroke by causing the brain to make more blood vessels. The logic is that, by inducing the formation of more blood vessels in the brain, more blood would flow to the brain area that suffered the injury. The increased blood flow would, therefore, help relieve the oxygen deprivation in the brain. Some propose that a single agent that could provide both neuroprotection and angiogenesis would appear to be the most promising. Of the various chemicals tested through the years that are both neuroprotective and increase the formation of blood vessels, few have captured more attention than vascular endothelial growth factor (VEGF). This substance accomplishes both things, but also has several negative side effects. One of the major side effects of this chemical is to cause the blood vessels to become permeable, or porous, so that blood fluids and substances in the blood leak out of the blood vessels into the brain. Thus, though VEGF may create new blood vessels in the brain, it can also cause the blood vessels that are already in the brain to become leaky. Even the new blood vessels that are formed are also permeable. It is, therefore, unclear whether VEGF could safely and effectively be used to cause neuroprotection and angiogenesis in the brain at the same time. Manoonkitiwongsa and his colleagues have conducted experiments to determine whether neuroprotection and angiogenesis by VEGF necessarily occur together. Their data, published in the June 24 Journal of Cerebral Blood Flow and Metabolism, reveal that neuroprotection and angiogenesis maybe inversely related. That is, VEGF may be neuroprotective only as long as angiogenesis does not occur. When angiogenesis is significantly induced, VEGF no longer protects the brain, and creating more vessels may inflict further injury to the brain and worsen the consequences of stroke. They believe that VEGF could be a strong candidate for stroke therapy when used for neuroprotection, but that induction of angiogenesis by VEGF should be avoided by controlling the dosage. "Our data are very preliminary," says Manoonkitiwongsa. "More dosages need to be tested to confirm our hypothesis." They recently submitted a grant proposal to the National Institutes of Health for the purposes of 1) deciphering the relationship between neuroprotection and angiogenesis by VEGF and 2) characterizing the alterations in the brain exposed to the various doses of VEGF. Once these are precisely identified, and the mechanisms responsible for the relationships are elucidated, they hope to resolve whether neuroprotection and angiogenesis by VEGF can concurrently and safely be used as treatment methods for stroke. Neural Engineering Laboratory director Doug McCreery, Ph.D., said of this project, "Their research will provide significant and critical knowledge and bridge an important gap in our current understanding of stroke treatment."

Prevention Helps Too

Education about stroke prevention encourages reducing risk through healthful living - e.g. cessation of smoking and consumption of intoxicants, sufficient exercise, proper diet, weight control, sugar control and stress management. However, "at-risk" behaviors do not change quickly. The fact is, many of the general public do smoke, consume alcohol to excess, pursue sedentary work or activities for much of the time, do not exercise regularly, do not control their caloric intake, and are subjected to the mental and psychological stresses of everyday life. Furthermore, as a person advances in age, the brain and its blood vessels become weaker and more susceptible to stroke. With the more sedentary lifestyle that comes with advancing age, its probability increases further. The lifetime costs of therapy and medication per person are estimated to be $200,000 for hemorrhagic stroke and $100,000 for ischemic stroke. Inpatient hospital costs alone average about $30,000 per admission for hemorrhagic stroke and $10,000 for ischemic stroke. These expenses are in addition to physician services and other costs. Statistics show that more than 500,000 stroke episodes occur in the USA each year of which one-third are fatal. In 2002 alone, more than 700,000 strokes occurred in the USA, of which approximately 500,000 were first-ever strokes and 200,000 were recurrent strokes. If the age-specific rates of stroke remain unchanged from 2002 to 2025, the overall number of strokes in the USA will increase from approximately 700,000 in 2002 to 1,136, 000 in 2025.

Development of electronic neurological implants by Huntington Medical Research Institutes (HMRI), a nonprofit biomedical research organization based in Pasadena, California, recently drew the attention of more than one hundred leaders of Asia's semiconductor micro-fabrication industry. On March 19-20, 2009, industry representatives from Taiwan, Japan, and Korea convened in Hisinchu, Taiwan for the First International Conference on Neuroprosthetic Devices (ICND), an event designed to enhance West-East interaction and collaboration in the rapidly advancing clinical use of neuroprosthetics and to introduce Taiwan's engineering community to this industry's unique technological and neurological research opportunities. Victor Pikov, Ph.D., a researcher, neural engineer and neurophysiologist with the HMRI Neural Engineering laboratory, chaired the conference's international organizing committee. Guest speakers recruited by Dr. Pikov and his committee included physicians and scientists from HMRI, Harvard Medical School, Massachusetts General Hospital, Mayo Clinic, University of Pennsylvania, and the University of California at Los Angeles. Douglas McCreery, Ph.D., director of the HMRI Neural Engineering Program and one of the nation's foremost experts on electrical stimulation of the nervous system, joined Dr. Pikov as guest speaker and representative of HMRI. Key areas covered during the presentations in neural prosthetics applications including deep brain stimulation for treatment of Parkinson's disease, brain recordings for detection and prediction of epilepsy, auditory prostheses, and devices for reanimating muscles paralyzed after spinal cord injury. Each presentation addressed current issues encountered in the development and design of neural prosthetic devices such as improved biocompatibility, development of carbon nanotube coatings for neural recording and stimulating electrodes, photolithographic electrode technologies, and the incorporation of photosensors and other active electronic components on retinal visual prostheses. The conference was sponsored by the National Chiao Tung University, Taiwan's chief academic establishment in the field of semiconductor technologies and electrical engineering. This university is closely affiliated with the Hsinchu Science-based Industrial Park; one of a number of advanced technology sites in Taiwan created to bring together industrial, research and academic resources and talents.
