Medical Xpress / Enzyme technology clears first human test toward universal donor organs for transplantation
The first successful human transplant of a kidney converted from blood type A to universal type O used special enzymes developed at the University of British Columbia to help prevent a mismatch and rejection of the organ.
Medical Xpress / Glioblastomas affect much more than just the brain, scientists discover
Scientists at Montefiore Einstein Comprehensive Cancer Center (MECCC) and Albert Einstein College of Medicine have shown for the first time that glioblastoma—the deadliest form of brain cancer—affects not just the brain ...
Medical Xpress / High-density brain probe reveals distinctive electrical patterns of cell types during behavior
Trying to document how single brain cells participate in networks that govern behavior is a daunting task. Brain probes called Neuropixels, which feature high-density silicon arrays, have enabled scientists to collect electrophysiological ...
Medical Xpress / How better software choices could cut US health care costs
Denied insurance claims are among the biggest challenges facing the U.S. health care system—driving up costs and leaving providers with billions in unpaid bills.
Medical Xpress / Mitochondrial building block balance linked to age-related inflammation
Research led by the Max Planck Institute for Biology of Aging in Cologne reports that misincorporation of ribonucleotides into mitochondrial DNA (mtDNA) initiates an inflammatory cascade.
Medical Xpress / Early intake of the antidepressant fluoxetine alters brain development in rats, study finds
Past neuroscience studies have consistently showed the profound effects of early life experiences on the brain's wiring, particularly on the formation of the junctions that enable communication between neurons (i.e., synapses). ...
Medical Xpress / Genetic and behavioral links found between musical rhythm perception and developmental language disorders
In a paper published in Nature Communications, researchers at Vanderbilt University Medical Center's Department of Otolaryngology–Head and Neck Surgery leveraged two main studies—one focused on behavior and one focused ...
Medical Xpress / A link that persists: Education outshines heart health as predictor of memory in people over 90
An association between higher education and better brain health can still be seen in people over 90, according to a new study. In contrast, midlife risk factors for cardiovascular disease were not found to be linked to memory ...
Medical Xpress / Circadian clock protein linked to brain aging and neurodegenerative disease
Impeding a link between the body's natural clock and the brain may help reduce neurodegeneration in mice modeling Alzheimer's disease, according to a new study led by researchers at WashU Medicine and published in Nature ...
Medical Xpress / Psilocybin targets brain circuits to relieve chronic pain and depression, study suggests
Researchers at Penn Medicine have identified specific brain circuits that are impacted by psilocybin—the active compound found in some psychedelic mushrooms—which could lead to new paths forward for pain and mental health ...
Medical Xpress / Tiny cell messengers in obese individuals accelerate Alzheimer's-linked plaque buildup in the brain, study finds
Obesity has long been acknowledged as a risk factor for a wide range of diseases, but a more precise link between obesity and Alzheimer's disease has remained a mystery—until now.
Dialog / Designing brain–computer interfaces is now easier than building with LEGO
Imagine being able to compose an email or steer a wheelchair directly with your thoughts. For millions of people living with neurological disorders such as ALS, this possibility could be life-changing. Their ability to think ...
