In a new study published in Liver Research, a team of researchers in China discovered that nicotinic acid-a common form of vitamin B3-can dramatically reduce liver damage caused by ischemia-reperfusion injury (IRI), a major complication in liver surgery and transplantation.

Understanding sevoflurane-induced neurogenesis inhibition and cognitive dysfunction in children

Rss Feed - Mon, 01/05/2026 - 22:09
Every year, millions of infants and children undergo surgery under general anesthesia in the world. Sevoflurane is a commonly used pediatric anesthetic. Its exposure during brain development has been shown to inhibit neurogenesis and cause cognitive dysfunction in animal models.

Can ketogenic diets help PCOS? New analysis points to weight and insulin gains

Rss Feed - Mon, 01/05/2026 - 22:09
A systematic review and meta-analysis of 15 studies found that ketogenic diets were associated with short-term reductions in body weight, waist circumference, insulin resistance, and some reproductive hormones in women with polycystic ovary syndrome, primarily among those with overweight or obesity. However, substantial heterogeneity, low certainty of evidence, limited safety reporting, and short follow-up periods mean the clinical effectiveness and long-term sustainability of ketogenic diets in PCOS remain uncertain.

Vitamin A derivative suppresses immune response and cancer vaccine efficacy

Rss Feed - Mon, 01/05/2026 - 22:03
Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.

Scientists at St. Jude Children's Research Hospital have revealed previously unappreciated roles for the retrotransposon LINE-1 in shaping the cancer genome structure and regulation.

Finger-prick blood tests enable remote detection of Alzheimer’s biomarkers

Rss Feed - Mon, 01/05/2026 - 21:25
A groundbreaking international study has demonstrated that Alzheimer's disease biomarkers can be accurately detected using simple finger-prick blood samples that can be collected at home and mailed to laboratories without refrigeration or prior processing.

COVID-19 immunity stays specific and barely boosts protection against common cold coronaviruses

Rss Feed - Mon, 01/05/2026 - 21:23
This study shows that SARS-CoV-2 infection and vaccination generate strong, highly specific spike-binding immune responses with only modest effects on immunity to endemic common cold coronaviruses. Pre-existing coronavirus immunity patterns remain largely intact, indicating that SARS-CoV-2 has integrated into the human viral landscape without broadly reshaping cross-reactive protection.
