by University of Bristol Credit: Unsplash/CC0 Public Domain Smoking cigarettes may increase the risk of a heart attack by activating a gene that affects blood clotting, according to a new study by scientists at the University of Bristol. The study, published in Circulation Research, used a multidisciplinary approach involving four different study designs, including data from...
by Karolinska Institutet Graphical absract. Credit: DOI: 10.1172/JCI155094 There has to date been no reliable objective method of diagnosing tinnitus. Researchers from Karolinska Institutet now show that brainstem audiometry can be used to measure changes in the brain in people with constant tinnitus. The study has been published in the Journal of Clinical Investigation. Tinnitus is...

However, lab tests also showed that the available antibody therapies—typically given intravenously in hospitals—are substantially less effective against omicron than against earlier...
by University of Nottingham Credit: Pixabay/CC0 Public Domain New research has shown that over-activity in a specific area of the brain is linked to certain symptoms of schizophrenia, opening up possibilities for the development of more targeted treatments. Researchers from the University of Nottingham found that faulty inhibitory neurotransmission and abnormally increased activity in the...

This is from an individual with the APOE ε3/3 genotype (Case 1068). In the depicted plaque-like structure, the ApoE signal is strongest in the...
by Brigham and Women’s Hospital Credit: Pixabay/CC0 Public Domain Autoimmune diseases (AD) such as rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease and psoriasis, are a leading cause of morbidity and mortality as people age. Few effective treatments are available for AD, but some preclinical studies have hinted that supplements, including vitamin D and omega-3 (or...

The spike protein (foreground) enables the virus to enter and infect human cells. On the virus model, the virus surface (blue) is covered with spike proteins (red)...
by Pennsylvania State University Credit: Pixabay/CC0 Public Domain People with Parkinson’s disease who eat more flavonoids—compounds found in richly colored foods like berries, cocoa, and red wine—may have a lower mortality risk than those who don’t, according to a new study. Specifically, the researchers found that when people who had already been diagnosed with Parkinson’s...
