Medical Xpress / Diabetes flips immune cells from repair to inflammation in peripheral artery disease, study finds
Type 2 diabetes can turn immune cells that help with tissue repair and anti-inflammatory responses into triggers of chronic inflammation. A recent study investigated why people with type 2 diabetes are at a higher risk of ...
Medical Xpress / An endurance limit that surfaces in punishing races may begin at birth
A new study is raising questions about whether human endurance has biological limits shaped long before adulthood—possibly beginning at birth. Researchers are examining whether birth weight, a known risk factor for disease ...
Medical Xpress / Brazilian tree compounds block SARS-CoV-2 at multiple stages, lab tests show
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus ...
Medical Xpress / Genetic discovery may explain why pancreatic cancer is so difficult to treat
Pancreatic cancer can remain quiet for years, developing undetected before causing symptoms that lead to a diagnosis. Even after a surgeon removes a pancreas tumor, other cells often hide and erupt later. But University of ...
Medical Xpress / AI surpasses physicians on clinical reasoning tasks, raising the bar for more serious testing
In one of the largest studies to compare artificial intelligence and physicians on a wide array of clinical reasoning tasks including real emergency department data, a team of physicians and computer scientists at Harvard ...
Medical Xpress / Silencing stress signals could pave the way to a longer life
Silencing a major cellular stress signal could be the key to a longer life, according to new University of Sheffield research. While previous studies suggested that mild stress might help organisms live longer, new research ...
Medical Xpress / Glucose levels appear to guide when brain cells divide or form myelin
Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have uncovered a surprising link between low brain sugar levels and the development of myelin—the protective coating that allows ...
Medical Xpress / For 30 years, doctors chased the wrong immune culprit behind this rare inflammatory disease
Researchers at the Garvan Institute of Medical Research have uncovered a critical mechanism driving inflammation in mevalonate kinase deficiency (MKD), a rare but devastating autoinflammatory disorder. The study, published ...
Medical Xpress / T cells secrete DNA to boost the immune system's cancer-fighting ability
Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell Medicine. The discovery ...
Medical Xpress / Restoring protein recycling helps exhausted T cells fight tumors again
T cells are crucial components of our immune system, serving as critical protectors against infection and disease. But there are limits to their defensive capabilities. T cells are not inexhaustible protectors. Often, when ...
Medical Xpress / No live animal testing needed: Lab-grown airway organoids reveal viral infection in wildlife species
Experimental infections, where a pathogen is introduced into the host body to see its effects in action, are considered the gold standard for assessing how vulnerable a host is, offering clear insights into how a pathogen ...
Medical Xpress / Communication from the CDC fuels skepticism about vaccines and science, research suggests
The scientific consensus is that vaccinations are neither causally nor statistically linked to autism. The US health authority CDC changed its official communication on this matter and instead emphasized a connection could ...
