Scientists capture picture of 'MicroRNA' in action

Biologists at The Scripps Research Institute (TSRI) have described the atomic-level workings of "microRNA" molecules, which control the expression of genes in all animals and plants. The findings add greatly to the understanding of a fundamental system of regulation in biology, and should accelerate the development of therapies that harness its power.

Scientists find genetic variants influence a person's response to statins

A large analysis of over 40,000 individuals on statin treatment has identified two new genetic variants which influence how 'bad' cholesterol levels respond to statin therapy. Statins are widely prescribed to patients and have been shown to lower bad cholesterol levels by up to 55%, making them a highly effective method of reducing risk of heart disease.

Clinical trial could change standard treatment for stroke

A large international clinical trial has shed new light on the effectiveness of current hospital protocols for managing blood pressure in stroke patients. The two-part ENOS trial (Efficacy of Nitric Oxide in Stroke,) was carried out at The University of Nottingham in collaboration with 23 countries to try to solve two major conundrums faced by doctors when treating people who have suffered a stroke

Protecting us from our cells

Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body's natural defence against this 'friendly fire', scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have found.

Analgesics and anti-inflammatory drugs may have an impact on depression

Ordinary over the counter painkillers and anti-inflammatory drugs purchased from pharmacies may also be effective in the treatment of people suffering of depression. This is shown by the largest ever meta-analysis that has just been published by a research group from Aarhus University in the journal JAMA Psychiatry.
