Parkinson"s disease mutation misdirects iron in the brain
A common gene mutation for Parkinson's disease drives mislocalization of iron in activated microglia, according to a new study. The results may help explain the accumulation of toxic iron in affected brain areas in the disease and provide a basis for.....»»
COVID-19 may have spread faster in United States because first symptom was cough
The strain of COVID-19 virus that was circulating in the United States and Europe during the first wave of the pandemic may have been particularly infectious because the most common first symptom was likely a cough, according to a new study......»»
For IBS, specific diets are less important than expected
Many IBS sufferers avoid certain types of food and often exclude gluten. However, a large new study does not show a relationship between high intake of gluten and increased IBS symptoms. The researchers did find that a certain type of carbohydrate ca.....»»
Study shows how HIV copies itself in the body
HIV replication in the human body requires that specific viral RNAs be packaged into progeny virus particles. A new study has found how a small difference in the RNA sequence can allow the viral RNA to be packaged for replication, creating potential.....»»

New discovery on how omega-3 fatty acids can reduce atherosclerosis
A receptor activated by substances formed from omega-3 fatty acids plays a vital role in preventing inflammation in blood vessels and reducing atherosclerosis, a new study reports. The discovery can pave the way for new strategies for treating and pr.....»»
New study reveals how epithelial cells in the body naturally eliminate "precancerous" ones
Normal epithelial cells show the ability to push out precancerous ones present in the epithelium, by means of 'cell competition.' But the exact molecular mechanism of this recognition by normal epithelial cells was unknown. Now, researchers have unra.....»»
Gallic acid and stretching decrease osteoarthritis markers in cartilage cells
Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination no.....»»
