Medical Xpress / Deep brain ultrasound uncovers pain-processing network tied to heat sensitivity changes
A new noninvasive neurostimulation technique capable of reaching deep regions of the brain has been used to elucidate the brain's pain mechanisms, with promising clinical applications in neurology and psychiatry. Described ...
Medical Xpress / COVID-19 may leave placental damage, but virus disappears after maternal recovery
A new Yale study published in JAMA Network Open finds that the virus that causes COVID-19 does not linger in placental tissue weeks to months after a pregnant woman recovers from infection—offering important reassurance for ...
Medical Xpress / Microfluidic chip reveals how living glioblastoma slices resist chemotherapy
Combining microchip engineering techniques with cutting-edge gene profiling, scientists at Columbia University have developed a new way to study drug responses in living slices of human brain tumor cells. The system, using ...
Medical Xpress / Low-dose triple-pill cuts risk of recurrent stroke by about 40%, global trial shows
Treatment with GMRx2, a single pill combination of three low-dose blood pressure medicines, significantly reduced the risk of another stroke in patients with intracerebral hemorrhage and high blood pressure. Results from ...
Medical Xpress / COVID antiviral speeds recovery but doesn't reduce hospitalization in vaccinated patients, trials find
Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials published ...
Medical Xpress / Why electroconvulsive therapy remains contested: Families report memory loss, worse quality of life and limited benefits
Electroconvulsive therapy (ECT), which involves passing electricity through the brain under general anesthesia to cause a seizure, usually between six and 12 times, is used to varying degrees around the world for patients ...
Medical Xpress / Molecular 'switch' that fuels cancer progression discovered
Researchers from the University of Cape Town's (UCT) Scientific Computing Research Unit (SCRU) have uncovered a critical molecular "switch" that drives the formation of cancer-associated antigens. The study, published in ...
Medical Xpress / How an anti-inflammatory drug helps the heart after a heart attack
Every day, thousands of people worldwide suffer a heart attack, often leading to lasting damage to the heart muscle. Recent research from the University of Oslo suggests that targeting inflammation in the body helps protect ...
Medical Xpress / New clues to hepatitis B species restriction could help build a novel model for studying infection
Some 254 million people live with a chronic hepatitis B (HBV) infection that is often asymptomatic for decades, only to emerge in an advanced stage of disease that turns to fatal cirrhosis or liver cancer in nearly a million ...
Medical Xpress / New tool can see how different brain cell types work together
When probes are inserted into the brain for research or clinical purposes, the electrical activity of neurons is recorded. These signals can be used to understand how the brain performs certain computations or even to identify ...
Medical Xpress / Fixed or flexible? Study shows vision-related neurons can rapidly switch codes
For many years, a dominant view in neuroscience was that neurons in the inferotemporal (IT) cortex—a critical center in the brain for the recognition of objects—represent the world through fixed tuning functions. Doris Tsao ...
Medical Xpress / New glioblastoma clue could lead to therapies that weaken tumors and boost immune memory
A team of researchers from Brown University Health and Brown University has uncovered an important clue in the fight against glioblastoma, the most common and aggressive form of brain cancer in adults.
