Retinal Imaging And Machine Learning Honored In The 2023 Lasker Awards

Many ophthalmologists’ offices around the country are home to a machine that enables doctors to take advantage of optical coherence tomography (OCT), a method of imaging the retina and other tissues in the eye. These OCT machines give doctors insight into the three-dimensional structures of their patients’ eyes, help them diagnose diseases and can even help save their patients’ sight.

The genesis of OCT machines began in the lab of Dr. James Fujimoto, who was inspired by advances in high-speed photography and lasers to start developing potential methods that would enable doctors to get better images of what was happening inside of people’s bodies. The goal, he told Forbes, was to develop… More.

In 1991, the trio published their first paper describing the technique they invented. “In less than a year, we were able to develop this new imaging technology, which in retrospect was pretty unusual,” Huang told Forbes.

Since the publication of that first paper, OCT has grown into a nearly $2 billion market. Doctors now routinely use the technology to diagnose diseases such as glaucoma, diabetes-related vision impairment and even coronary artery disease. “The impact on public health can be very large,” Fujimoto said. “If you can preserve vision, for example, to the point where patients can continue to drive a car, that’s a major change in lifestyle and an impact on quality of life.”

On Thursday, the Lasker Foundation awarded Fujimoto, Huang and Swanson its annual $250,000 award for Clinical Medical Research. The Foundation has been handing out its annual awards since 1945, which this year include two other categories: Basic Medical Research and Special Achievement in Medical Science. Many winners of these prizes have often gone on to win other scientific honors, including the Nobel Prize.

Exploring the mind-mitochondria connection

As befits the child of a scientist, Martin Picard’s young son, 3, is already learning about biology with an age-appropriate textbook, “Cell Biology for Babies.” Picard winces a little whenever the book calls mitochondria the “powerhouses of the cell” but figures he has plenty of time as his son grows older to explain why the tiny organelles are much more than simple energy sources.

Picard is a leading proponent of mitochondrial psychobiology (a phrase he coined), an emerging field that examines how psychological states like stress influence mitochondrial functions, which in turn influence mental and physical health.

“The powerhouse analogy is outdated and one-dimensional and can impede science by limiting researchers’ perceptions of what mitochondria can do,” says Picard, associate professor of behavioral medicine in psychiatry and neurology.

How AI can help us understand how cells work—and help cure diseases

A virtual cell modeling system, powered by AI, will lead to breakthroughs in our understanding of diseases, argue the cofounders of the Chan Zuckerberg Initiative.

As the smallest living units, cells are key to understanding disease—and yet so much about them remains unknown. We do not know, for example, how billions of biomolecules—like DNA, proteins, and lipids—come together to act as one cell. Nor do we know how our many types of cells interact within our bodies. We have limited understanding of how cells, tissues, and organs become diseased and what it takes for them to be healthy.

AI can help us answer these questions and apply that knowledge to improve health and well-being worldwide—if… More.

Artificial womb human trials may soon inch closer to reality

CHOP researchers established the feasibility of an artificial womb called the “Biobag” to nurture a premature lamb in 2017.

The US Food and Drug Administration (FDA) will hold a meeting of independent advisors on September 19–20. The meeting’s agenda is to discuss the viability of clinical trials using artificial womb technology to improve the survival and health of extremely preterm newborns.

Reportedly, during this meeting, regulators and experts will delve into ethical concerns and evaluate various crucial aspects, including the potential steps and design of human trials for this technology.

Exposure to plasticizers in pregnancy associated with smaller volumetric measures in the brain and lower IQ in children

Children whose mothers had a higher exposure to certain phthalates during pregnancy tend to show smaller total gray matter in their brains at age 10. This is one of the main conclusions of a study led by the NYU Grossman School of Medicine and the Barcelona Institute for Global Health (ISGlobal), and published in Molecular Psychiatry.

The study also found that to plasticizers during pregnancy is associated with lower child IQ at age 14, which confirmed the results of two previous study on the topic. Moreover, the research team observed that this relationship between exposure to certain phthalates and lower child IQ is partially influenced by total gray matter volumes. In other words: exposure to plasticizers before birth could lead to smaller total gray matter in childhood, which in turn could be related to a lower IQ.

Finally, the results showed an association between gestational exposure to plasticizers and smaller white matter volumes in girls.

Sweeping Discovery — Scientists Discover a Previously Unknown “Housekeeping” Process in Kidney Cells

Scientists from the University of Texas at Dallas have identified a previously unknown “housekeeping” process in kidney cells that ejects unwanted content, resulting in cells that rejuvenate themselves and remain functioning and healthy.

This unique self-renewal method, distinct from known regeneration processes in other body tissues, sheds light on how the kidneys can maintain their health throughout one’s life in the absence of injury or illness. The team detailed their findings in a study recently published in Nature Nanotechnology.

Unlike the liver and skin, where cells divide to create new daughter cells and regenerate the organ, cells in the proximal tubules of the kidney are mitotically quiescent — they do not divide to create new cells. In cases of a mild injury or disease, kidney cells do have limited repair capabilities, and stem cells in the kidney can form new kidney cells, but only up to a point, said Dr. Jie Zheng, professor of chemistry and biochemistry in the School of Natural Sciences and Mathematics and co-corresponding author of the study.

Pioneering CBD For Epilepsy Treatment And Prevention

A Texas A&M University professor and a team of pharmacology researchers are spearheading advances in the use of medical cannabinoids for epilepsy and seizure disorders.

A team led by Dr. D. Samba Reddy, a Regents Professor in the Department of Neuroscience and Experimental Therapeutics at the Texas A&M University School of Medicine, has made progress in determining efficacy, safety and new applications of cannabinoid therapeutics. Reddy’s work establishes a foundation for tailored and effective epilepsy treatments, offering hope to those facing its challenges.

The team’s research on epilepsy has resulted in the publication of five key papers featured in the May 2023 issue of the journal Experimental Neurology.

“The medical cannabis research originated from the patient families and advocates in Colorado who have witnessed the positive effects of medical cannabis products,” said Reddy, who is a founding director of the Texas A&M Health Institute of Pharmacology and Neurotherapeutics.

Pharmacology research team reveals breakthrough findings on cannabinoid therapy for preventing epilepsy and refractory seizure disorders.

Higher buprenorphine doses associated with improved retention in treatment for opioid use disorder

NIH-funded study suggests need to reevaluate opioid addiction treatment recommendations in the era of fentanyl.

Individuals with opioid use disorder who were prescribed a lower buprenorphine dose were 20% more likely to discontinue treatment than those on a higher dose, according to a study of patients prescribed buprenorphine in Rhode Island from 2016 to 2020, as fentanyl became widely available. The study, published today in JAMA Network Open, was supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and conducted by researchers at Brown University, Providence, Rhode Island; NIDA and the Rhode Island Department of Health.

Among patients newly initiating buprenorphine treatment for opioid use disorder, 59% of those prescribed the target daily dose of 16 milligrams recommended by the U.S. Food and Drug Administration and 53% of those prescribed the higher 24 mg daily dose discontinued treatment within 180 days. A statistical analysis that allowed for multivariable comparison of these two dose groups showed patients prescribed the recommended dose (16 mg) were significantly more likely to discontinue treatment over 180 days compared to those prescribed 24 mg.
