Researchers discover a way to make fat cells skinny
Posted Yesterday Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered a key biological reason why obesity increases the risk of Type 2 diabetes, and it boils down to size — specifically the size of fat cells. Fat – illustrative photo. Image credit: Pixabay (Free Pixabay license) The study, published in...

African men most at risk of prostate cancer—new study flags genetic causes
by Wenlong Carl Chen, The Conversation Credit: Unsplash/CC0 Public Domain A breakthrough study has identified the genetic risk factors that contribute to increased prostate cancer in African men. The study, the largest of its kind, recruited 7,500 men from eastern, southern and west Africa. The study is especially important because African men have a high risk...

New research reveals two types of fatty liver disease
by Karolinska Institutet Putative model of the two different types of MASLD. Credit: Nature Medicine (2024). DOI: 10.1038/s41591-024-03284-0 Researchers at Karolinska Institutet and the University of Gothenburg have identified two types of metabolic-associated fatty liver disease—a liver-specific type and a systemic type that affects other organs and tissues. The discovery could lead to improved diagnosis and treatment of...

Stomach cancer can be caused by a bacterium carried by half the people on Earth, but screening for it isn’t easy
by Delthia Ricks , Medical Xpress Credit: Pixabay/CC0 Public Domain In 1982, two Australian physician–scientists discovered a spiral-shaped bacterium whose form not only dictated its function, but its capacity to dwell in the human body’s harshest chemical environment would help identify it as the cause of serious afflictions of the stomach, including cancer. Drs. Barry...

Neuron-based research model helps decode rare neurological disease
by Tel-Aviv University Differential effects of TIMM50 mutation on the expression of TIM23, PAM and TOM subunits and matrix-destined proteins. Credit: eLife (2024). DOI: 10.7554/eLife.99914.2 Researchers at Tel Aviv University have developed an innovative research model that allowed them to decode the mechanism underlying a severe and rare neurological disease. The disease is characterized by symptoms such as...

MASH discovery redefines subtypes with distinct risks: shaping the future of fatty liver disease treatment
Peer-Reviewed Publication INSERM (Institut national de la santé et de la recherche médicale) Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly referred to as nonalcoholic fatty liver disease (NAFLD), impacts roughly 30% of the global adult population. The disease spans from benign fat accumulation in the liver (steatosis) to its more severe form, metabolic dysfunction-associated steatohepatitis...

Study links high-fiber diet to delayed progression of blood cancer
by Memorial Sloan Kettering Cancer Center Credit: Unsplash/CC0 Public Domain Researchers at Memorial Sloan Kettering Cancer Center (MSK) have reported results from the first-ever clinical trial demonstrating that a high-fiber, plant-based dietary intervention may delay progression to multiple myeloma, a rare and incurable blood cancer affecting the bone marrow. The study enrolled 20 participants with a precancerous blood...

New AI stroke brain scan readings are twice as accurate as current method
by Samantha Rey06 December 2024 view large AI pinpoints stroke timing, treatment potential from a single scan New AI software can read the brain scans of patients who have had a stroke, to more accurately pinpoint when it happened and help doctors work out whether it can be successfully treated. It is hoped that the new...
