Medical Xpress / Dozens of genes tied to OCD and tic disorders discovered
A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk of obsessive-compulsive disorder (OCD) and chronic tic disorders—providing, two researchers said, the most detailed biological ...
Medical Xpress / Brain blood flow responds differently to pain and touch, mouse study finds
When the brain is stimulated, blood flow increases. For 30 years, functional magnetic resonance imaging (fMRI), one of the most powerful windows into the human brain, has operated on the basis of this connection. fMRI doesn't ...
Medical Xpress / Stress and depression, not heart damage, may drive long-term breast cancer fatigue
For breast cancer survivors, new research shows that feelings of depression and perceptions of psychological stress make the biggest difference in whether they experience fatigue up to two years after chemotherapy started.
Medical Xpress / Atlas of the brain's striatum could guide researchers to new drug treatments
A region of the brain called the striatum is critical for many cognitive and motor functions, including decision-making, movement control, habit formation and reward processing. It also plays a role in addiction and is significantly ...
Medical Xpress / Bacterial protein fragment drives tissue fibrosis, but antibody treatment can help
A bacterial protein fragment called corisin drives pulmonary fibrosis by infiltrating and disrupting cells' quality-control systems, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found ...
Medical Xpress / Imaging technique reveals the metabolic states of individual immune cells
When a patient is facing certain cancers or an immune condition, clinicians turn to white blood cells for clues about the progression of both diseases and their treatments. From a standard blood draw, a clinical lab isolates ...
Medical Xpress / Severe asthma remains active in most despite widespread biologic treatment
Severe asthma affects around 5%–10% of all people with asthma and can involve recurrent exacerbations, impaired lung function and the need for corticosteroid treatment. In recent years, biologic therapies have improved treatment ...
Medical Xpress / Gut bacterium and its metabolite found to delay aging
A new study published in Nature Aging on Aug. 25 reports that a single gut bacterium—Bifidobacterium pseudocatenulatum (BP)—together with a small molecule it produces, 5-aminovaleric acid betaine (5-AVAB), can alleviate multiple ...
Medical Xpress / Preeclampsia discovery could lead to new test and treatments for at-risk pregnancies
Cambridge scientists have identified a key protein that could act as a predictor for preeclampsia and fetal growth restriction, two of the major causes of stillbirth and illness among mothers and newborns. The discovery helps ...
Medical Xpress / Clinical aging clocks uncover different metabolic turning points for men and women
Aging varies markedly among individuals and between sexes, yet the timing of major physiological transitions and the factors driving these changes have not been well understood.
Medical Xpress / Migraine may leave bodywide clues, AI analysis of 43,000 people suggests
A new study from NTNU—the Norwegian University of Science and Technology—reveals that migraine may leave a biological pattern throughout the body, traces of which can be identified by artificial intelligence. Researchers ...
Medical Xpress / Antifungal therapy shows potential for IBD patients with Candida overgrowth
A commonly used systemic antifungal medication may help reduce symptoms in a subset of patients with inflammatory bowel disease (IBD) by restoring a healthier gut microbiome, according to a preliminary study by Weill Cornell ...
