Brain Receptor Thought To Be Linked To Negative Moods Identified

A receptor believed to be linked to negative moods, in a part of the brain that is little-understood, has been uncovered by an international research team. The discovery[1] could lead to more targeted medications. The pea-sized receptor was found in a little-studied region in the center of the human brain, the medial habenula. “The function […]

Anti-inflammatory Agents Can Safely Suppress Major Depression Symptoms

Anti-inflammatory agents, such as aspirin/paracetamol, statins, and antibiotics, can safely and effectively curb the symptoms of major depression, finds a newly published meta-analysis of the available evidence. And the effects are even stronger when these agents are added on to standard antidepressant treatment, the results show. Around a third of people who are clinically depressed […]

Brain Tissue Kept Alive For Weeks On Artificial Membrane

A new system for keeping tissue viable for long-term study once transferred from an animal to a culture medium has been developed by researchers at the RIKEN Center for Biosystems Dynamics Research in Japan. The new system[1] uses a microfluidic device that can keep tissue from both drying out and from drowning in fluid. A […]

How Folk Medicines For Blood Pressure Work

Common herbs, including lavender, fennel, and chamomile, have a long history as folk medicines used to lower blood pressure. New research explains the molecular mechanisms at work. The study[1] illustrates how many of the known traditional botanical plants used to lower blood pressure activate a specific potassium channel (KCNQ5) in blood vessels. “We found KCNQ5 […]

New Flavonoid Compound May Promote Healing Of Myelin

Damage to myelin caused by inflammatory oligodendrocyte cell destruction combined with axon degeneration are two of the signs of multiple sclerosis (MS). Most of the available medications for MS are approved for relapsing–remitting (RR) MS, for which they reduce relapse rate, MRI measures of inflammation, and the accumulation of disability. But these medications are of […]
