Scientists believe that they have found a chemical responsible for increasing cardiovascular risk, it was revealed. And crucially they have identified how it is made and destroyed in the body raising the possibilty that new drugs to reduce the risk of heart disease are around the corner. A team of scientists based at the new British Heart Foundation (BHF) Laboratories at UCL first identified ADMA as a naturally occurring substance that blocks the production of a gas made by the body – Nitric Oxide.

Adolescents from families where mealtimes and other activities are shared seem to have fewer mental health problems, reports a study in the Journal of Epidemiology and Community Health.

Researchers assessed the family habits and rituals of 82 first time users, aged between 14 and 23, of mental health services in one metropolitan area. Anxiety and depression were the main problems for which treatment was sought. Family practices in 177 young people within the same age band from various educa

Middle aged men should be heartened to know that frequent sex is not likely to increase their risk of stroke. It may actually reduce the risk of sudden death, suggests research in the Journal of Epidemiology and Community Health.

The Caerphilly study, which takes its name from a former mining town in South Wales, involves tracking the development of heart disease in almost 3000 men. All were aged between 45 and 59 when recruited to the study between 1979 and 1983.

Cellular attack tactic keeps virus at bay.

A new AIDS vaccine could be one of the most promising yet. The drug’s effects in monkeys suggest that killing virus-laden cells may form a key part of future vaccination strategies.

Vaccinated monkeys survived a usually lethal infection with a monkey-human hybrid virus, SHIV. Their primed immune system kept virus levels below detection, Emilio Emini of Merck Research Laboratories in West Point, Pennsylvania, and his team now report

Radiologists in Nottingham have discovered a fast and accurate technique to diagnose deep vein thrombosis (DVT), which may be particularly helpful to pregnant women and travellers at risk of developing dangerous blood clots.

In a study funded by the British Heart Foundation and published this week in the American journal, the Annals of Internal Medicine, (15 January 2002, volume 136, number 2) Professor Alan Moody and his team in the department of academic radiology at the University of Nott

Missing protein leaves mice impervious to pain

Researchers have a new lead for treating pain. A protein called DREAM appears to play a key role in how mice respond to heat, touch and inflammation 1 .

Mice lacking DREAM seem oblivious to all types of pain, find Josef Penninger and his colleagues at The AMGEN Institute, Toronto, Canada. The animals can bear acute pain – the kind caused for example by heat, pressure, or injections as well as chronic inflammatory
