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 / 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 / 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 / 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.
Medical Xpress / Targeting two proteins to prevent pulmonary hypertension
UIC researchers have identified two therapeutic targets for pulmonary arterial hypertension, an as-yet-incurable disease that can be caused by a parasite laying eggs in the abdomen. The targets represent an opportunity to ...
Medical Xpress / Novel spatial technology may improve our understanding of cancer biology
Northwestern Medicine scientists have developed a novel high-resolution spatial genomics platform that may enhance future research into how genome organization and genetic alterations contribute to disease development, including ...
Medical Xpress / Mini-tumors reveal new drug combinations for liver cancer
Liver cancer is difficult to treat because tumors vary greatly from patient to patient. Researchers at the University of Basel have captured this diversity by creating a collection of mini-tumors, which they use to systematically ...
Medical Xpress / Lab-grown tissue reveals how inflammation may drive heart relaxation failure
Scientists study the underlying causes of a disease or test potential new drugs in animal models or cells obtained from human biopsy specimens before clinical trials. However, disease models in animals do not mimic actual ...
Medical Xpress / Neuropsychologist finds gaps between treatment and science of ALS, dementia in her own family
For A. Campbell Sullivan, PsyD, this time it's personal. As a neuropsychologist and clinical associate professor of neurology at the Glenn Biggs Institute for Alzheimer's and Neurodegenerative Diseases at UT Health San Antonio, ...
