Medical Xpress / Blocking a female-only GABA signal that helps glioblastoma evade immunity may boost survival
Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females. The study shows that the ...
Medical Xpress / What one sleepless night does to brain connections and why sleep may reset them
A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology ...
Medical Xpress / Most IVF 'add-ons' show little evidence of boosting births, researchers find
There is a lack of evidence to suggest the majority of in vitro fertilization (IVF) add-ons improve fertility in patients undergoing IVF, according to a systematic review and meta-analysis published in The Lancet Obstetrics, ...
Medical Xpress / Discovery of BIRC3 gene variants in Crohn's disease yields a druggable pathway
Researchers from The Hospital for Sick Children (SickKids) in Toronto have found a previously unknown genetic cause of Crohn's disease and uncovered how those changes trigger inflammation through a key immune pathway. The ...
Medical Xpress / Fat tissue could explain triple negative breast cancer spread—and point to treatments
Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at ...
Medical Xpress / Steep drop in metabolic coenzyme could trigger preterm labor
Declining placental concentrations of a molecule that plays a key role in metabolism appear to trigger the end of pregnancy and hasten labor and delivery, suggesting a study co-led by researchers at UT Southwestern Medical ...
Medical Xpress / Gut fungi may hold the key to treating asthma worldwide
Two new studies jointly published in Nature Communications reveal that certain species of fungi in the gut play a key role in the development of immune dysregulation and some pediatric allergic diseases—and may be promising ...
Medical Xpress / Low testosterone linked to cancer risk in men
New research shows men with very low testosterone levels are at higher risk of both fatal and nonfatal cancer later in life. But while the research found men with low testosterone were 18% more likely to die of cancer years ...
Medical Xpress / AI may help avoid unnecessary chemotherapy for breast cancer patients
Research led by RCSI University of Medicine and Health Sciences and University College Dublin (UCD) has identified immune markers that could help doctors more accurately determine which breast cancer patients are unlikely ...
Medical Xpress / Faster breast MRI—AI unlocks one image per second and sharper tumor tracking
A group of researchers from the Technion and the United States reports a breakthrough in MRI scanning in a paper published in Nature Communications. The researchers developed an innovative method that accelerates and enhances ...
Medical Xpress / Link between parents' and children's weight is mostly genetic, study finds
The association between parents' body mass index (BMI) and their children's childhood BMI may be primarily due to genetic inheritance rather than any direct biological effect of parental weight during pregnancy, according ...
Medical Xpress / Spontaneous and voluntary laughter come from two different brain regions, researchers reveal
Laughter is a universal social signal that connects us with others, but the brain regions underlying laughter are not well understood, in part because it's hard to elicit genuine laughter in the lab.
