Studies have shown that patients suffering from depression or schizophrenia often have immunological alterations that can be detected in the blood. Others reported a possible link between inflammation, a microgliosis and the blood-brain barrier (BBB) in suicidal patients. Serum S100B is a marker... Read More
From time to time, we dip into the microbiology blog by César Sánchez, Twisted Bacteria, and, with his permission, "borrow" a post such as this one about pneumonia and pneumococci, fratricide at the cellular level, and a pretty protein. And there's a video too!
"A few days ago I w... Read More
Since water is a necessity of life, it is important to drink water free from contaminants. To treat water and make it worth drinking, different processes are used and one of best treatment methods is Reverse Osmosis. In this process of water filtration, the water goes through semi permeable memb... Read More
