University of Missouri researchers discovered that bullfrogs can produce ketone bodies directly in their brains when glucose levels are low, creating a built-in backup fuel source that helps keep critical neural functions running during energy shortages. The finding not only explains how bullfrogs survive the extreme conditions of winter dormancy but could also provide new insights into human neurological disorders such as Alzheimer's disease, ALS and schizophrenia, which are linked to impaired brain energy metabolism.
Nikolaos P. Daskalakis, MD, PhD, professor of pharmacology, physiology & biophysics at Boston University Chobanian & Avedisian School of Medicine, has been awarded the XXIV “Vexillum G. Sciacca” International Award for Medical Research. The award ceremony, which took place September 26 at the Vatican, honored Daskalakis for his outstanding contribution to the field of neuropsychiatric and mental health research. This annual event honors young talents and individuals who have distinguished themselves in various sectors of civil society.
The Tan Family Scholarship Fund has awarded Boston University Chobanian & Avedisian School of Medicine $180,000 over three years to provide scholarships to six medical students in years two, three and four of their studies.
Gastric cancer remains a major global health challenge, and therapeutic resistance continues to limit the effectiveness of existing HER2-targeted treatments. A research team from Jiangsu University has developed a bispecific cellular nanovesicle platform that simultaneously targets CD16-positive natural killer (NK) cells and HER2-positive gastric cancer cells. The engineered nanovesicles enhance NK cell recruitment, activation, cytokine secretion, and tumor-killing activity, providing a promising strategy for next-generation cancer immunotherapy.
UVA Comprehensive Cancer Center will welcome top scientists and physicians working to understand and stop cancer’s metastatic spread for its sixth-annual Michael J. Weber Symposium on Oct. 2.
In a study of 54 adults with sleep disturbances and mild cognitive impairments (MCI), two hallmarks of early dementia, participants taking at least 5,000 IU of vitamin D daily showed better cognitive function compared to those who didn’t. The study, recently published in Sleep Medicine, found that participants who reported taking 5,000 IU or more of vitamin D daily scored more than 13% higher on the Montreal Cognitive Assessment (MoCA), even after accounting for other factors. A screening tool to detect risk of developing dementia, MoCA is widely used to assess memory and thinking skills. In this study, lower daily doses of vitamin D were not associated with higher cognitive scores.
