Medical Xpress / Researchers uncover critical genetic drivers of the gut's 'nervous system' development
Vanderbilt researchers, including those from the Vanderbilt Brain Institute, have made significant strides in understanding how the enteric nervous system—sometimes called the "brain" of the gut—forms and functions.
Medical Xpress / Microfluidic platform with label-free sorting can assess neutrophil function in sepsis
Sepsis arises from infection and immune dysregulation. Neutrophils play a key role in its progression, yet existing clinical tools cannot simultaneously isolate these cells and measure their functional activity.
Medical Xpress / New insights into the epigenetic processes via which neuroinflammation causes memory loss
Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance, have found that neuroinflammation ...
Medical Xpress / Prolonged use of injectable contraceptive tied to brain tumor diagnoses
From Case Western Reserve University School of Medicine and Cleveland Clinic, investigators report that depot medroxyprogesterone acetate use was associated with a higher relative risk of meningioma brain tumor diagnosis ...
Medical Xpress / Meal timing in later life may matter for health and longevity
As we age, what and how much we eat tends to change. However, how meal timing relates to health remains less understood. Researchers at Mass General Brigham and their collaborators studied changes to meal timing in older ...
Medical Xpress / New antibiotic to fight superbug C. diff proves effective in clinical trial
As the effectiveness of antibiotics meant to fight the deadly superbug Clostridioides difficile, or C. diff, wanes, a research team at the University of Houston is seeing positive results of a new antibiotic on the scene—ibezapolstat—which ...
Medical Xpress / Extensive sequencing study finds few links between cancer and microbiome
About a dozen studies in the past five years have made claims linking nearly every type of human cancer with the presence of microbiomes, "communities" of bacteria, viruses and fungi that live in or on people's bodies. Now, ...
Medical Xpress / Can the 'good' bacteria in your mouth act as probiotic cavity fighters?
If UC Berkeley's Wenjun Zhang has her way, no one will ever have to brush or floss again.
Medical Xpress / Single hair strand could provide biomarker for amyotrophic lateral sclerosis
Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from ...
Medical Xpress / How an autism-linked mutation reduces vasopressin and alters social behavior
A team of researchers has identified for the first time the mechanism linking a mutation in the Shank3 gene with alterations in social behavior. Using a mouse model carrying this autism-associated mutation, the study shows ...
Medical Xpress / Researchers reveal potential molecular link between air pollutants and increased risk of Lewy body dementia
A team of researchers at Johns Hopkins Medicine say they have revealed a possible molecular connection between air pollution and an increased risk of developing Lewy body dementia.
Medical Xpress / Inflammation jolts 'sleeping' cancer cells awake, enabling them to multiply again
Cancer cells have one relentless goal: to grow and divide. While most stick together within the original tumor, some rogue cells break away to traverse to distant organs. There, they can lie dormant—undetectable and not ...
