Ketamine has received a lot of attention as a potential treatment for depression, but few studies have revealed how well it works in real world settings, especially in patients with complex mental health needs.  Now, a new study of data from veterans who had tried many depression treatments but still had severe symptoms suggests a series of intravenous doses of ketamine gave many at least partial relief. For a minority, it led to full remission.  Nearly half of 215 veterans with treatment resistant depression who received ...

Protein molecules lie at the heart of biology. Our typical understanding of proteins states that each type of protein has a specific three-dimensional shape that enables it to perform its function. This dogma is challenged by intrinsically disordered proteins which make up one third of all proteins and have central biological functions even though their shapes are constantly changing. Until now, our understanding of the structural properties of this intriguing class of proteins has been based on studies ...

A team of scientists from the University of Ottawa, and researchers from other universities and research centres around the world, have discovered that 7-dehydrocholesterol (7-DHC) is an endogenous suppressor of ferroptosis, which could have important implications for the treatment of cell death-related diseases. Ferroptosis is a form of cell death that is characterized by the accumulation of lipid peroxides and iron-dependent reactive oxygen species (ROS) in cells. It is a regulated process that is distinct from other forms of cell death, such as apoptosis and necrosis. The researchers identified a pro-ferroptotic activity of 7-dehydrocholesterol reductase (DHCR7) ...
