All mammals, including humans, rely on outer hair cells in the ear’s cochlea to amplify...
Do your headaches happen at the same time of day?
AMERICAN ACADEMY OF NEUROLOGY EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, MARCH 29, 2023 MINNEAPOLIS – Both cluster headache and migraine have strong links to the circadian system, the internal clock that regulates body processes, according to a meta-analysis published in the March 29, 2023, online issue of Neurology®, the medical journal of the American Academy of...
Fibroblast inhibitors assist anti-cancer drugs to suppress cancer growth
by American Institute of Physics A 3D co-culture system mimics the tumor microenvironment for studying the impact of drug combinations. An anti-fibrotic drug, nintedanib, could improve the effect of an anti-cancer drug, cisplatin, to reduce tumor growth and invasion.

Bacterial Toxin May Trigger Multiple Sclerosis Onset and Relapse
Summary: Findings reveal a toxin-producing gut bacteria may be responsible for triggering the onset of multiple sclerosis and play a significant role in the progression of the disease. Source: Cornell University A specific toxin-producing gut bacteria may be responsible for both triggering the onset of multiple sclerosis (MS) and ongoing disease activity, according to a new study...
