Public urged to visit emergency departments for serious cases only – The Peninsula

Doha, Qatar: Hamad Medical Corporation (HMC) is encouraging the public to only visit emergency departments for serious, medical emergencies that require immediate intervention.

This follows the launch of a joint campaign by the Ministry of Public Health (MoPH), Hamad Medical Corporation (HMC), Public Health Care Corporation (PHCC), Sidra Medicine and Qatar Red Crescent Society (QRCS) to raise awareness of emergency and urgent healthcare services in Qatar. The five-week campaign named Where For Your Care? aims to help patients make the best choice for their medical care needs and receive the best possible care. The seven emergency departments and five paediatric emergency centres at HMC operate 24 hours a day and provide emergency care for serious medical cases.

Dr. Aftab Mohammad Umar, Chair of Emergency Medicine at HMC, said that The role of the emergency departments at HMC is to deliver immediate medical care for the most seriously injured or sick patients and are specifically staffed and resourced to do so. We are committed to treating all emergency cases, but we do prioritise the needs of those with the most critical conditions first to ensure that the right medical care is provided to the right group of patients.

To better serve the community and manage healthcare resources efficiently, the Where For Your Care? campaign advises the public to make the best choice for their healthcare needs for life-threatening emergencies such as chest pain, choking, stroke, difficulty in breathing, heart attack or unconsciousness, people should call 999 immediately for an ambulance.

For non-life-threatening emergencies such as a significant deep cut, broken bone, abdominal pain, allergic reaction that does not restrict the airway or significant burn, public are asked to immediately make their own way, if possible, to the nearest emergency department.

For a non-emergency condition that cannot wait for an appointment at a health center such as a sprain, fever, eye/nose/throat complaint, mild respiratory issue or minor burn, public are requested to visit a PHCC or QRC urgent care centre that is accessible 24/7.

For mental health support, public should call 16000, Saturday to Thursday, 8am to 6pm. For support out of these times that cannot wait, people should visit any emergency department.

Richard Tempel: Restricting adult access to hemp products are unnecessary and could have unintended health … – Florida Politics

Each year, the Florida Legislature proposes new measures aimed at improving the safety and well-being of Floridians. We are fortunate to live in a state where our elected officials are proactive in prioritizing the health of our families, loved ones and neighbors but sometimes good intentions can miss the mark.

As a board-certified emergency medicine specialist with over 20 years of experience, I have concerns regarding Senate Bill 1698, Hemp and Food Products. While I support the bills intent to protect children from inadvertently consuming hemp products, I believe the proposed restrictions on adult access to hemp-derived cannabinoids are unnecessary and could have unintended health consequences.

Throughout my career, including my tenure on the board of the American Medical Marijuana Physicians Association and as medical director for a Florida medical marijuana treatment center, I have gained extensive insight into the therapeutic potential of cannabinoids. It is well-established in scientific literature that hemp-derived cannabinoids are safe for adult use in doses up to 1500 mg per day. For conditions like Crohns disease, effective management can often require a substantial daily mix of cannabinoids. Overly restrictive regulations on these compounds could result in prolonged patient suffering and potentially lead to individuals seeking unsafe and unregulated alternatives.

In my years practicing emergency medicine, Ive treated children who have ingested or been exposed to cannabis products. While such instances are indeed concerning, it is important to note that the typical treatment for these children in the ER is straightforward hydration and rest. This approach is generally sufficient to manage the situation effectively, indicating that while it is crucial to prevent accidental ingestion, the response to such incidents is well-established and not typically severe.

The current legislative framework, established by the Florida Legislature last year, effectively addresses the risk of children mistaking hemp products for candy or snacks. Further restrictions proposed in SB 1698 could impede access to therapeutic products by adults, many of whom rely on them for significant health benefits.

The drug overdose crisis is a significant concern, and as a physician on the front lines, I understand the importance of safe and regulated access to effective medical treatments. However, limiting access to safer alternatives like hemp-derived cannabinoids could inadvertently exacerbate this crisis.

A more effective and balanced approach would be to focus SB 1698 on enhancing the child safety measures passed last year and supporting public education about responsible storage and use of hemp products in homes with children. The current language of SB 1698 and its companion, HB 1613, would hinder access to hemp products that many Floridians rely on to improve their quality of life. It is crucial to ensure that adults, especially those seeking medical benefits from these products, retain access to them.

Emerging trends in health crisis and disaster management revealed at Arab Health 2024 – BSA bureau

"A robust governance framework, well-defined standards and policies critical to an effective response system. AI, telehealth, digital transformation and telematics are increasingly playing a critical role in managing disaster situations" explains Dr Al Ali, EMS and Disaster Medicine at the Department of Health Abu Dhabi

A leading expert in health crisis and disaster management has underscored the importance of pre-hospital care, hospital services, and enabling services, including laboratories and training programs in disaster management, as we move from classical operations to technology-driven disaster medicine.

Speaking at the Public Health Conference on the emerging trends in health crisis and disaster, Dr Saleh Fares Al Ali, Consultant of Emergency Medicine, EMS and Disaster Medicine at the Department of Health Abu Dhabi, andH.E. Dr Amer Sharif, CEO of Dubai Health shared their insights

Dr Saleh Fares Al Ali, Consultant of Emergency Medicine, EMS and Disaster Medicine at the Department of Health Abu Dhab:

Dr Al Alirevealed disaster management involves more than just having an ambulance on standby at the emergency department.

It encompasses a wide range of services and requires a comprehensive approach to governance. This includes pre-hospital care, hospital services, and enabling services, including laboratories, training programs, and even poison centres. To effectively manage disasters, we must consider all of these elements as part of a larger system, said Dr Al Ali.

An effective response system requires a robust governance framework, well-defined standards, and policies. Additionally, you need an efficient operation centre to connect all the dots. It's crucial to cover all domains, from pre-hospital to hospital to enabling services, to create a well-orchestrated system, he added.

Some of the key trends discussed by Dr Al Aliwere technology and its critical role in managing disasters, where he underscored the importance of artificial intelligence (AI), telehealth, digital transformation and telematics and outlining how AI enhances medical diagnosis and triage by swiftly and accurately analysing patient data, predicting outcomes, and offering treatment recommendations; additionally, AI-driven chatbots provide real-time medical guidance to first responders.

Telehealth technologies help enhance access to medical expertise, expedite remote consultations between prehospital providers and physicians, and optimise resource allocation, benefiting patients in rural or underserved areas by saving critical time during emergencies.

The burgeoning industry of advanced data insights utilises digital twins, enabling virtual replicas of entities such as emergency departments or ambulance systems, fostering crisis management, and employing predictive analytics to mobilise resources proactively, exemplified by anticipating ambulance needs at events such as Arab Health due to the volume of people gathering in one area.

Finally, telematics systems in ambulances, utilising 5G connectivity, offer real-time tracking for location, speed, and status, enhancing response times and route optimisation. Dr Al Ali highlighted a prototype collaboration between the Department of Health in Abu Dhabi and Etisalat whereby ultrasound images to hospitals will be transferred through this technology.

Elsewhere on the agenda at Arab Health, Dubai Health, the first integrated academic health system in Dubai presented a comprehensive overview of Dubai's first integrated academic health system model.

H.E. Dr Amer Sharif, CEO of Dubai Health:

Through a unified commitment to patient-centred care, we are not just shaping the present healthcare landscape, but also laying the foundation for a transformative future anchored in our primary value of 'Patient First. This commitment extends beyond the present, as we strive to create a lasting impact on the lives and wellbeing of our community for generations to come explained Dr Sharif.

Arab Health 2024concludes on1 February 2024, at the Dubai World Trade Centre, when the winners of the Innov8 startup competition will be revealed. The competition included 24 health-tech startups pitching unique concepts and innovations. The winners of the Cre8 competition will also be revealed. The competition has been designed to foster creativity and innovation among participating students in the UAE. Contestants were required to conceptualise and innovate a solution for an actual healthcare problem within an imaginary AED 100,000 budget.

USM Chemistry (Biochemistry Emphasis) Degree Earns ASBMB Reaccreditation – The University of Southern Mississippi

Wed, 01/31/2024 - 01:21pm | By: Ivonne Kawas

The University of Southern Mississippis (USM) B.S. degree in Chemistry (Biochemistry emphasis) has earned reaccreditation by the leading agency in the field of life sciences the American Society for Biochemistry and Molecular Biology (ASBMB).

This accreditation was obtained for the first time in 2017. Obtaining ASBMB accreditation, a national outcomes-based evaluation, ensures programs in the field meet the highest standards of academic excellence. USMs chemistry degree program is housed in the School of Mathematics and Natural Sciences (MANS),

Accreditation by ASBMB is a testament to the quality and content of our biochemistry curriculum, as well as to the knowledge and skills learned by our students as they begin to seek careers or further their studies at the graduate or professional levels, said Dr. Chris Winstead, dean of the College of Arts and Sciences. I appreciate the effort of the faculty in seeking this accreditation. This shows their dedication to providing the best preparation possible for our Southern Miss students, an education that is well-aligned with national standards and prepares them for their next steps.

Dr. Vijay Rangachari, professor of chemistry and biochemistry, emphasizes one of the direct accreditation benefits for students.

ASBMB accreditation inherently enhances the value of the students degree, allowing them to include on their resume that they graduated from an ASBMB-accredited program. Furthermore, upon degree completion, they can demonstrate competitiveness on a national scale by obtaining ASBMB certification.

Dr. Rangachari also highlights one of the strengths of the program, integral to both student success and ASBMB accreditation: the hands-on research opportunities provided in the laboratory.

To meet accreditation requirements, the curricula must include over 400 hours of hands-on laboratory experience. Therefore, students get an advantage in advancing their careers.

Students like Landon Lee, a native of Hattiesburg, Miss. who is pursuing the biochemistry emphasis, actively participate in cutting-edge research projects in the lab, alongside graduate students and faculty mentors.

Joining a research lab has significantly enriched my educational experience, as Ive been able to acquire skills related to academic research, project management, and creative thinking, said Lee. With the support and guidance from both the graduate students in my lab and Dr. Rangachari, my faculty mentor, it has become more than just a platform for applying classroom concepts; it has provided me a community that fosters my personal and academic development.

After completing his bachelors degree, Lee plans to further his studies: As I complete my degree, I intend to pursue a Ph.D. in neuroscience. My coursework has undoubtedly laid a strong foundation in physics, chemistry, and mathematics, enabling me to demonstrate key strengths as I strive toward this goal.

Dr. Theofanis Kitsopoulos, director in the School of MANS, reflects on the programs successful and highly valued alumni base, as it opens doors to diverse industries.

Our curriculum is carefully crafted to equip students not only with a strong theoretical foundation but also with practical skills highly valued in the job market, said Dr. Kitsopoulos. Several of our alumni choose to pursue advanced degrees in prestigious graduate programs in medical, dental, pharmaceutical, and other professional schools. They go on to succeed in diverse industries such as research and development, healthcare, environmental consulting, forensic science, and entrepreneurship. Some thrive as quality control and analytical chemists, while others pursue fulfilling paths as middle and high school science and chemistry teachers.

AI generates proteins with exceptional binding strength – ASBMB Today

A new studyin Nature reports an AI-driven advance in biotechnology with implications for drug development, disease detection, and environmental monitoring. Scientists at the Institute for Protein Design at the University of Washington School of Medicine used software to create protein molecules that bind with exceptionally high affinity and specificity to a variety of challenging biomarkers, including human hormones. Notably, the scientists achieved the highest interaction strength ever reported between a computer-generated biomolecule and its target.

Senior author David Baker, professor of biochemistry at UW Medicine, Howard Hughes Medical Institute investigator, and recipient of the 2023 Frontiers of Knowledge Award in Biology and Biomedicine, emphasized the potential impact: "The ability to generate novel proteins with such high binding affinity and specificity opens up a world of possibilities, from new disease treatments to advanced diagnostics."

Ian Haydon/UW Medicine Institute for Protein Design

A new protein designed using deep-learning methods. In this case, RFdiffusion generates a binding protein.

The team, led by Baker Lab members Susana Vazquez-Torres, Preetham Venkatesh, and Phil Leung, set out to create proteins that could bind to glucagon, neuropeptide Y, parathyroid hormone, and other helical peptide targets. Such molecules, crucial in biological systems, are especially difficult for drugs and diagnostic tools to recognize because they often lack stable molecular structures. Antibodies can be used to detect some of these medically relevant targets but are often costly to produce and have limited shelf lives.

"There are many diseases that are difficult to treat today simply because it is so challenging to detect certain molecules in the body. As tools for diagnosis, designed proteins may offer a more cost-effective alternative to antibodies," explained Venkatesh.

The study introduces a novel protein design approach that uses advanced deep-learning methods. The researchers present a new way of using RFdiffusion, a generative model for creating new protein shapes, in conjunction with the sequence-design tool ProteinMPNN. Developed in the Baker Lab, these programs allow scientists to create functional proteins more efficiently than ever before. By combining these tools in new ways, the team generated binding proteins by using limited target information, such as a peptide's amino acid sequence alone. The broad implications of this "build to fit" approach suggest a new era in biotechnology in which AI-generated proteins can be used to detect complex molecules relevant to human health and the environment.

"We're witnessing an exciting era in protein design, where advanced artificial intelligence tools, like the ones featured in our study, are accelerating the improvement of protein activity. This breakthrough is set to redefine the landscape of biotechnology," noted Vazquez-Torres.

In collaboration with the Joseph Rogers Lab at the University of Copenhagen and the Andrew Hoofnagle Lab at UW Medicine, the team conducted laboratory tests to validate their biodesign methods. Mass spectrometry was used to detect designed proteins that bind to low-concentration peptides in human serum, thereby demonstrating the potential for sensitive and accurate disease diagnostics. Additionally, the proteins were found to retain their target binding abilities despite harsh conditions including high heat, a crucial attribute for real-world application. Further showcasing the method's potential, the researchers integrated a high-affinity parathyroid hormone binder into a biosensor system and achieved a 21-fold increase in bioluminescence signal in samples that contained the target hormone. This integration into a diagnostic device highlights the immediate practical applications of AI-generated proteins.

The study, which illustrates the confluence of biotechnology and artificial intelligence and sets a new precedent in both fields, appears in Nature with the title De novo design of high-affinity binders of bioactive helical peptides.

Cheetahs Are Extremely Inbred: 50 Interesting Genetics Facts You May Have Missed At School – Bored Panda

There is a gene called TP53 - its referred to as the guardian of the genome - it is a tumor suppressor gene and prevents cancer of all types. Humans have two copies and if one is broken/mutated it causes an inherited condition called Li Fraumeni. People with this have a very very high risks for cancer, and the condition can be passed down in families. Elephants have 20 copies of TP53 and therefore rarely get cancer. The Li Fraumeni foundation uses the elephant as its mascot and hopefully we can someday figure out how to replace faulty TP53 genes for these families.

Perhaps my favourite biology fact is about pharmacogenetics, how your genetics determines the efficacy of drugs on your system due to prevalence of receptors of different types that the drugs target to produce an effect:

"90% of drugs only work on 30-50% of the population."

I find it so truly wild. But most people I've talked to about it seem to agree that some drug or other doesn't work for them. This really highlights how much of a process finding the right drug for a person is. I had a lecture on this in uni in about 2016 and it said the future of pharmacology is individual genetic screens for drug effectiveness meaning people don't have to keep trying different drugs until they find the one that works, you would be tested then your doctor would have that info. I just hope it overcomes the pushback from Big Pharma in my lifetime cause it would be a true game-changer.

While it might sound like a cross between dystopian fiction and body horror, some researchers believe that there is a lot of potential to store data and information in our DNA. After all, in one sense, thats exactly what DNAs actual function is. That being said, most of us probably dont want to walk around with our own DNA turned into a sort of USB flash stick when we can literally buy this device in most stores.

Comically, as sci-fi as this idea sounds, it might already be out of date. Research into this topic has found that encoding data into our DNA is not only more costly but less reliable and slower to read than the various means of data storage we already have. So if you really want to get cyberpunk, perhaps get a QR code tattooed or investigate the wonderful world of chipping your palms.

That if you unraveled all of the DNA in your body, and stretched it out in a straight line, you'd be dead.

If you set aside ethics and set out to do it, it would only take 33 generations to create a human being who was the descendant of everyone currently alive and able to have children.

Also, pedigree collapse: no living person has as many unique ancestors as they mathematically should. Every person has, biologically, 2 parents, 4 grandparents, 8 great-grandparents, etc, doubling every generation. 30 generations back without any degree of inbreeding would require over a billion unique 28x great grandparents, more than the entire world population for 1100 AD. Every single human's family tree is full of people marrying and having children with cousins of some genetically-unimportant degree over the last thousand years.

1. Most genetics studies were, and are still, done on white western populations. Some things that we "know" about genetics turn out to not work so well in non-white or non-western populations. Loose example: diagnostic tests to check for certain diseases sometimes misdiagnose Americans with African ancestry, because sometimes we don't actually know exactly how certain diseases will look in non-European ancestry patients, we just assume it will be the same.

2. Africa, as a whole, is the most genetically diverse continent for human genetics. Humans outside of Africa went through a population bottleneck, resulting in an overall lack of diversity moving forward. The human blender of genetics in Europe just didn't have many starting ingredients. There are things called linkage disequilibrium maps, which basically map out sections of the genome that are usually found inherited together. In Europe, these maps are quite "chunky", with large identifiable sections that are sort of reliably found intact. But in Africa, the blender was always running and never had a bottleneck, so those maps are basically a much finer puree, with a lot more mixing. This presents certain challenges, as many studies rely on those maps to make predictions, and it's harder to do that when the map for Africa as a whole is basically way more complex.

3. Everyone's cancer is its own unique genetic disease. There is no one true single disease called "lung cancer", just as there is no one single true human genome. Everyone is genetically unique (yes even identical twins), and every cancer is unique.

4. Chromothripsis is a thing where a chromosome pretty much shatters and gets stuck back together all out of order. And... this is sometimes okay. There are cases of people who have chromosomes that have undergone chromothripsis, and they have mild to moderate symptoms, but they're not dead, which is miraculous.

5. Remember in biology class when you learn about mitosis? And there's that step called metaphase where all the chromosomes line up in a line before being separated into two new cells? That spot in the middle of the "X"-shaped chromosomes where the spindles attach to line them up is called the centromere. And it's sort of mysterious black hole of genetics. There aren't usually any genes there, just a chaotic cluster-f**k of repetitive sequence that gets chopped forwards, backwards, repeated 7 times, swapped around and repeated again, etc etc in an area that's hundreds of thousands of nucleotides long. But what's even crazier is that we don't really know *why* they are how or where they are, because *you don't need the wacky wasteland of repeats for them to work*. Almost all centromeres in all animals look like this, but there are exceptions. A very notable exception is that very very rarely in humans, a "mar-del" chromosome can form where a chromosome accidentally loops on itself and pinches (think of that heart thing people do with their thumb and forefinger), resulting in a circular chromosome that still has its centromere, and a "butterfly" chromosome that does not. Without a centromere, a chromosome can't be duplicated into daughter cells successfully, and cells can't live without the genes on that butterfly chromosome so this should be lethal if it happens early on in development. But surprise, a centromere can and has spontaneously formed on the butterfly chromosome, making them tiny, viable chromosomes that work pretty much fine! But like I said this is super rare, with only a few recorded cases ever. Centromeres in general are very cool and very mysterious.

6. Everything about modern next-generation genetic sequencing is super interesting, yet not well known to the general public. I won't brain dump about it, but if you want to know more, ask and I will!

When youre pregnant, bits of DNA from your baby invade your body and settle all over permanently - including in your brain. Researches found this by looking for male DNA in the brains of deceased 70 year olds. Interestingly, mouse studies have also shown that fetal cells within the mother have restorative properties and will rush to places like the heart, kidneys, lungs, liver if its injured and can even become cells that begin beating. One of the theories I have seen but I dont know if anyone knows for certain if this is true is that these cells enter our bodies so a host is less likely to reject the parasite baby.

I'm a geneticist with a mediocre master's degree in biology and currently pursuing a PhD in Bioinformatics. Here are some insights:

1. The accuracy of consumer and clinical genetic tests is often questionable due to the rapid pace of scientific advancements outpacing their application in the industry. The notable exceptions are information about Neanderthal ancestry (which is significant enough to have earned a Nobel Prize in Medicine) and a few critical mutations like the sickle cell variant and others related to blood.

2. Genetically, most humans are nearly identical, with differences being incredibly minute. This means that, barring age and sex, achieving success in various fields whether it's social, intelligence, or physical appearance is possible without genetic modifications. Everyone likely has a unique genetic trait that gives them a significant advantage, however. This is currently identifiable only in a lab setting. Understanding your unique trait, which often involves the expression of certain molecules, might require professional scientific interpretation.

3. Many severe genetic diseases, such as insulin-dependent diabetes, are only about 50% determined by genetics. Factors like early developmental conditions, including a mother's diet during early pregnancy and infections, play a paramount role.

4. Despite common belief, Neanderthals were not a separate species but rather a part of the human family. For perspective, Europeans and the Khoisan people of South Africa have been genetically divergent for about 300,000 years, not much less than the 500,000-year divergence between humans and Neanderthals.

5. Factors beyond genetics, such as living in a highly controlled environment (like a prison), having access to specific nutrition, owning a car and a separate house, and engaging in mental activities like language learning, math, statistics, and team video games, can significantly impact personal development. Genetics helps us understand and appreciate the influence of these non-genetic factors. The field of genetics is incredibly dynamic and continually evolving, offering many more fascinating insights.

4 new US sites added to global Parkinson’s genetics study – Parkinson’s News Today

University Hospitals (UH) healthcare system in Cleveland, Ohio, has been named one of four new sites for a Global Parkinsons Genetics Program (GP2) study that seeks to better understand Parkinsons disease in Black people, with a focus on the disorders genetic basis.

Improved knowledge of genetic variants linked to the progressive neurodegenerative disorder in this population could support the development of new treatments or the use of those being tested.

The other new sites in the Black and African American Connections to Parkinsons Disease (BLAAC PD) study, which opened in 2021, include UT Health in Houston, Texas; Washington University in St. Louis, Missouri; and the Medical University of South Carolina in Charleston, South Carolina.

Last March, the study added Louisiana State University and the University of Florida, joining the University of Alabama at Birmingham, Kaiser Permanente Mid-Atlantic, in Maryland, and two Illinois locations: Rush University and the University of Chicago.

The expansions broaden the BLAAC PD studys geographic reach and heighten representation of the diverse Black community in the U.S. They also build a foundation for greater discovery and application of findings across ancestries.

We are happy to be a part of the network of BLAAC PD sites across the U.S. and the GP2 global network in order to expand understanding of Parkinsons disease within the Black and African American communities, Camilla Kilbane, MD, director of UH Parkinsons and Movement Disorder Center, and medical director of the hospitals deep brain stimulation program, said in a press release.

We look forward to continuing to contribute to a more holistic, global understanding of Parkinsons Disease by increasing representation in our study populations and learning more about gene changes that may cause the disease.

Now part of the worlds largest Parkinsons genetics consortium, UH will receive funding for study visit expenses, supplies, community engagement strategy support, staffing support, and participant incentives.

Environmental as well as genetic factors are believed to contribute to the development of Parkinsons, a disease marked by movement difficulties and a progressive loss of coordination. GP2 seeks to address the fact that genetics research in Parkinsons has primarily focused on individuals of European descent. The study is part of the Aligning Science Across Parkinsons initiative, which aims to foster collaboration and resources to understand the underlying causes of Parkinsons.

In the U.S., the incidence of Parkinsons in Black people is estimated to be 23 of every 100,000, compared with 54 per 100,000 white people. The prevalence of the disorder is 50% lower in Black compared with white individuals. However, it is possible that this represents an underestimation of the true prevalence and incidence rate of Parkinsons among these racial groups.

Factors contributing to the disparities could include genetic or biological differences as well as systemic and structural healthcare factors such as the under-reporting of symptoms, patient mistrust in healthcare, and access to health insurance.

The BLAAC PD study intends to uncover the commonalities and differences between genetic lineages among Parkinsons patients. It is seeking adult participants from the Black or African American community, including patients and those without Parkinsons. Volunteers with a family history of Parkinsons are also eligible.

The study calls for blood or saliva samples to be collected one time from individuals in a single visit, along with demographics and medical and family histories. The samples will undergo DNA testing and be shared, along with BLAAC PD data, with the GP2 research community.

For the sake of participant privacy, only de-identified data will be shared. The goal of sharing is to facilitate the discovery of overlapping as well as population-specific variants linked to Parkinsons.

Study participants will be compensated but no medications will be provided. There is no cost to join BLAAC PD and also no charge to health insurance.

Nobel Laureate and World-Renowned Geneticist to Speak at 2024 Commencement – News Center – Feinberg News Center

Michael S. Brown, MD, director of the Jonsson Center for Molecular Genetics and the Regental Professor at the University of Texas (UT) Southwestern Medical School, will address graduates and their guests at Feinbergs 165th commencement ceremony on Monday, May 13.

Brown, along with his long-time colleague, Joseph Goldstein, MD, Chairman of the Department of Molecular Genetics at UT Southwestern Medical Center, discovered the low-density lipoprotein (LDL) receptor, which controls cholesterol in blood and in cells, and showed that mutations in this receptor cause Familial Hypercholesterolemia, a disorder that leads to premature heart attack.

Their work laid the groundwork for the development of statins that block cholesterol synthesis, increase LDL receptors, lower blood cholesterol and prevent heart attacks. Their discoveries earned them the Nobel Prize for Medicine or Physiology in 1985 and the U.S. National Medal of Science in 1988, among many other awards.

Brown earned his MD from the University of Pennsylvania School of Medicine in 1966 and completed an internship and internal medicine residency at Massachusetts General Hospital in 1968. He then became a Clinical Associate at the National Institutes of Health and in 1969, he joined the laboratory of Earl Stadtman at the National Institutes of Health as a postdoctoral fellow. In 1976, Brown was named the Paul J Thomas Professor of Medicine and Director of the Center for Genetic Diseases at UT Southwestern Medical School.

Brown and Goldstein have shared a laboratory for more than 50 years. The two scientists worked with scientists at Merck to develop the first statin drugs, which cause the liver to produce more LDL receptors, thereby removing more LDL from blood and lowering LDL levels. In 1987, Merck received FDA approval for the first statin drug, which was shown to effectively treat high blood cholesterol, reduce heart attacks and extended survival in adults with coronary heart disease. Today, statins are taken by more than 20 million Americans.

Brown is a member of the U.S. National Academy of Sciences, the National Academy of Medicine, the American Philosophical Society, and the American Academy of Arts and Sciences, and he is a Foreign Member of the Royal Society in London. Brown served for 16 years on the Board of Directors of Pfizer and is currently director of Regeneron Pharmaceuticals, where he chairs the Technology Committee.
