Nearly 30 years ago, researchers discovered two unusual molecules in rye pollen that appeared to slow tumor growth in animal studies. Despite the promising discovery, research stalled because scientists were unable to determine the exact three-dimensional structure of the molecule. Now, chemists at Northwestern University have solved this long-standing mystery. By building the molecules from scratch in the lab, we confirmed for the first time the exact structures of secarosides A and B. With a precise molecular blueprint now available, researchers are now able to investigate how compounds in rye pollen interact with the immune system. Rye pollen is derived…
Scientists have discovered an important reason why exercise is so effective at keeping aging muscles strong. A new study from Duke-NUS School of Medicine shows that physical activity restores the natural repair systems that weaken as we age, helping muscles recover and maintain function in old age. The research team, working with collaborators at Singapore General Hospital and Cardiff University, found that exercise can help correct important imbalances that occur within aging muscle cells. The survey results are Proceedings of the National Academy of Sciences (PNAS) provides new insights into the biological mechanisms behind muscle aging and may ultimately lead…
Recent research published in Lancet Health and Longevity suggest that while large-scale awareness campaigns can reach a wide audience, improvements in people’s knowledge about dementia prevention tend to be modest. However, a systematic review provides evidence that more interactive and personalized educational programs may be highly effective in promoting lifestyle changes that reduce the risk of dementia. This finding suggests that a targeted, community-led approach is needed to bridge the gap between simply knowing the risks and proactively changing daily habits. More than 57 million people around the world currently suffer from dementia. The number is expected to nearly triple…
Following the release of data from Assumption Parish earlier this year, researchers at the LSU Pennington Biomedical Research Center have announced the first dataset from the Rural Underlying Risk Longitudinal (RURAL) Heart and Lung Study in Franklin Parish. The Franklin Diocese data book is now available for viewing. The first-of-its-kind study was developed to investigate why people living in rural areas have disproportionately higher rates of heart disease, lung disease, stroke, diabetes and obesity. The longitudinal study, led by Dr. Stephanie Broyles, professor and director of the Contextual Risk Factors Institute at Pennington Biomedical, first collected data in Assumption Parish,…
In the United States, men were more likely than women to be diagnosed with local and/or distant stages of 20 types of non-reproductive solid cancers from 2015 to 2022, according to a study published in 2015-2022. Cancer epidemiology, biomarkers, and preventionJournal of the American Association for Cancer Research (AACR). The findings may provide insight into differences between men and women regarding cancer outcomes, the researchers noted. “Overall, we know that men are more likely than women to die from many types of cancer, and we also know that the stage of cancer at diagnosis is an important predictor of cancer…
Millions of people rely on statins, drugs used to lower cholesterol and reduce the risk of heart attack and stroke. However, for some people, this drug comes with undesirable trade-offs, such as muscle pain, weakness, and exercise intolerance, which can make it difficult to continue treatment. Now, researchers at McMaster University have discovered a biological pathway that may explain why these side effects occur, opening the door to future treatments that may make statins easier to tolerate while preserving their life-saving cardiovascular benefits. Published in scientific progressthis study identifies the immune and metabolic mechanisms that cause statin-induced muscle damage and…
The University of California, San Diego today announced the creation of the Applied Medical Intelligence Institute, an interdisciplinary hub aimed at leveraging the latest digital technologies to improve health care delivery and patient outcomes. As artificial intelligence (AI) accelerates health innovation, the Institute will leverage innovative ideas, backed by rigorous research and executed with agility, to achieve scalable and reliable health outcomes for everyone. The Institute reflects UC San Diego’s enduring commitment to innovation without boundaries. It embodies our strategic vision to transcend traditional silos, foster a culture of deep collaboration, and have a transformative impact on education, research…
The formation of supramolecular polymers within living cells is a new strategy to modulate cellular function, and lipid droplets (LDs) are a promising environment for such processes. LDs are cellular organelles whose main components are neutral lipids such as triacylglycerols and cholesterol esters, and are deeply involved in cellular functions. However, the self-assembly of supramolecular polymers in neutral lipid-rich environments such as LDs is not well understood. To this end, researchers at Nagoya University WPI-ITbM in Japan achieved the programmable construction of supramolecular polymers in triolein (TO), one of the most abundant lipid components of LDs. This study nature communications…
Matt Rothstein says his entire career, from Goldman Sachs to the National Library of Medicine, has been spent building “systems where technology and human achievement intersect.” “Regardless of sector, infrastructure is often broken or incentives are misaligned, resulting in a poor experience for those who need it most,” he told Fierce Healthcare. Mr. Rothstein co-founded Final, Inc., the predecessor to Apple Card, in 2012. He said the most important lesson learned from the development was “the discipline of building for real human moments.” Rothstein said this experience will be applied to healthcare to build solutions for everyone, especially those in…
Although Lyme disease is easiest to treat in its early stages, current tests often miss infections during that critical period and cannot determine whether the bacteria is still present or was eliminated years ago. A new study led by Tufts University School of Medicine suggests that a group of immune molecules called anti-lipid antibodies may be able to address these shortcomings. The results of this study were published in the Journal of the American Society for Microbiology. Infectious diseases and immunitythis could lead to improved tests to identify Lyme disease early if antibiotics can best prevent the more debilitating disease.…
