Medical Xpress / Exercise may train the brain to build endurance via SF1 neuron activity
Exercise does more than strengthen muscles; it also rewires the brain. In a study published in Neuron, researchers reveal that the lasting gain in endurance from repeated exercise—such as the ability to run farther and ...
Medical Xpress / Lung cancer drug offers a surprising new treatment against ovarian cancer
A new study published by Mayo Clinic researchers suggests that ovarian cancer cells quickly activate a survival response after PARP inhibitor treatment, and blocking this early response may make this class of drugs work better. ...
Medical Xpress / Multi-country malaria trial shows a more efficient way to treat the disease
Landmark findings from a major malaria clinical trial led by Menzies School of Health Research (Menzies) and international collaborators have confirmed the safety and effectiveness of two Plasmodium vivax (P. vivax) malaria ...
Medical Xpress / 3D imaging traces vascular amyloid spread in the human brain, from surface arteries to deeper vessels
Researchers at Niigata University have used advanced three-dimensional (3D) imaging to reveal how amyloid β (Aβ) deposits spread along blood vessels in the human brain in cerebral amyloid angiopathy (CAA). By analyzing ...
Medical Xpress / Mpox transmission model sheds light on a medical mystery
In a groundbreaking new study, a team of researchers from South Dakota State University—led by associate professor Saikat Basu—determined the critical exposure durations for inhaled transmission of pox viruses, including ...
Medical Xpress / Cancer cell study sheds light on cachexia's origins
New research from the University of Oklahoma, published today in Cancer Cell, describes for the first time a "triangle regulation theory" of cancer-induced cachexia and anorexia. Cachexia is a muscle-wasting and fat-loss ...
Medical Xpress / Unraveling the mystery of why some cancer treatments stop working
Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumors—and, in mice, they've found a way to neutralize ...
Medical Xpress / AI-built maps reveal causal gene regulation across Alzheimer's brain cell types
Researchers led by Min Zhang and Dabao Zhang of the University of California, Irvine's Joe C. Wen School of Population & Public Health have created the most detailed maps to date showing how genes causally regulate one another ...
Medical Xpress / Newly identified brain circuit and cells link prior experiences to appetite
Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate ...
Medical Xpress / Light-based sensor detects early molecular signs of cancer in the blood
Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer ...
Medical Xpress / Why visceral fat triggers diabetes: Study points to loss of protective macrophages
Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes—by boosting a special type of "good" immune cell in fat tissue.
Medical Xpress / Cholesterol crystals may trigger some liver disease
Cholesterol crystals in the liver may stiffen the organ early in those with metabolic dysfunction-associated steatotic liver disease (MASLD)—well before scarring develops—according to new research from a team in the Perelman ...
