Below are 10 science news that I found interesting and are related to topics I care about.

Depression linked to reduced arginine levels – People suffering from major depressive disorder, MDD, have reduced arginine levels, a new study from the University of Eastern Finland shows. Arginine is an amino acid which the body uses to produce, e.g., nitric oxide. Nitric oxide, in turn, is a nervous system and immune defence mediator, and it also plays a role in vascular regulation. The global arginine bioavailability ratio, GABR, is an indicator of the body’s arginine levels, and the ratio has previously been used to measure the body’s capacity to produce nitric oxide. Reduced arginine bioavailability is also known to be an independent risk factor of cardiovascular diseases. Science Daily

New stem-cell based stroke treatment repairs damaged brain tissue – A team of researchers at the University of Georgia’s Regenerative Bioscience Center and ArunA Biomedical, a UGA startup company, have developed a new treatment for stroke that reduces brain damage and accelerates the brain’s natural healing tendencies in animal models. They published their findings in the journal Translational Stroke Research. Science Daily
