Medical Xpress / Genetic pathway offers new insight into timing of early brain development
Melbourne researchers have uncovered a critical signaling pathway that controls the timing of brain development, shedding new light on how neurodevelopmental disorders may develop. The research, led by Murdoch Children's ...
Medical Xpress / Healthier fats linked to longer survival after prostate cancer diagnosis
Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health. For ...
Medical Xpress / Less-intensive drug combination is more effective in treating acute myeloid leukemia, clinical trial finds
Investigators from the Mass General Brigham Cancer Institute have found that adults with newly diagnosed acute myeloid leukemia (AML) receiving a less-intensive combination of azacitidine and venetoclax had more than twice ...
Medical Xpress / Why some stroke patients fare better than others
A clot forms. Blood flow to the brain is blocked. Starved of oxygen, neurons begin to die. This scenario, known as an ischemic stroke, plays out in roughly 21,000 people worldwide each day, threatening them with long-term ...
Medical Xpress / GLP-1 treatment late in life extends lifespan in animal model
A study published in Nature has shown that the GLP-1 drug semaglutide extended the lifespan of older, healthy mice by tempering the detrimental effects of aging. Researchers at the University of California, Berkeley, directly ...
Medical Xpress / Runner's high study finds cannabis-like signaling molecules rise over extreme distances
A marathon, 100 kilometers (62 miles) or even 230 kilometers (143 miles) in a single effort: Anyone running such distances puts enormous strain on their body. At the same time, levels of the body's own cannabis-like signaling ...
Medical Xpress / Tau's surprise birthplace offers a clue to how Alzheimer's tangles begin
Where and how does an Alzheimer's tangle begin? A new study by neuroscientists at Columbia University challenges a long-held assumption about the source of toxic tau proteins, which form neurofibrillary tangles and are closely ...
Medical Xpress / Breathing without brakes: An unexpected cause of Rett syndrome symptoms
Hyperventilating. Breath-holding until they turn blue. This abnormal breathing is frequent and disturbing in people with Rett syndrome, a rare genetic disease. Now University of Connecticut researchers report in Current Biology ...
Medical Xpress / Blocking a microRNA reverses deadly lung disease in multiple models
Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease.
Medical Xpress / Pre-surgery immunotherapy may improve treatment for deadly brain cancer
With a five-year survival rate of barely 5%, glioblastoma remains one of the deadliest brain cancers. First-line treatment consists of surgery to remove as much tumor tissue as possible.
Medical Xpress / Genetic tests may miss reaction risk from drug prescribed to millions
A genetic marker already used to flag the risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine—and it is missing from the gene panels clinicians ...
Medical Xpress / Daraxonrasib demonstrates initial antitumor activity in RAS-mutant lung cancer
Daraxonrasib, an oral RAS inhibitor therapy, achieved durable responses in pretreated patients with RAS-mutant non-small cell lung cancer (NSCLC) in a phase 1/2 trial led by The University of Texas MD Anderson Cancer Center.
