While most scientists believe that allergies cause asthma, researchers at Washington University School of Medicine in St. Louis are uncovering a second potential cause for this common respiratory illness. Their new model suggests that a viral infection in the first years of life may leave a lasting mark on the immune system, causing chronic respiratory problems later on. “While the allergic response may increase during an asthma attack, our research suggests that the anti-viral response also
A report in the July issue of the Journal of Clinical Investigation has found that a group of drugs currently under development for the treatment of Type II diabetes caused both increased heart rate and elevated blood pressure in animal studies. These new findings regarding glucagon-like peptide (GLP-1) receptor agonists suggest that the brains GLP-1 system has the ability to affect autonomic function, leading to changes in heart rate and blood pressure. A naturally occurring
Smokers who inherit a particular genetic trait could triple their chances of getting lung cancer according to a report in the British Journal of Cancer.* While tobacco is the biggest cause of lung cancer. the risk of developing it varies. This has led scientists to believe that genetics may have a crucial role in deciding who is most susceptible to the disease. German researchers have found that a quarter of patients with the most common form of lung cancer carry a particular version of a g
A significant milestone for British and European science occurred today [8th July 2002] when the Council of the European Southern Observatory (ESO) met in London. At this historic meeting the UK was formally welcomed into ESO by the other nine member states. The UK, one of the leading nations in astronomical research, now joins what is probably the world`s leading astronomical observatory. British astronomers now have access to some of the world`s most advanced telescopes and a major
Eating a diet rich in soya products such as tofu can affect the make-up of breast tissue, potentially reducing the risk of breast cancer, according to a new study* from Cancer Research UK.
Scientists have previously suggested that soya intake might contribute to the low rates of breast cancer in countries like China and Japan but research has proved inconclusive.
However, the new findings from a collaborative study involving scientists from the National University of Singapore, Can
A study in this week’s issue of THE LANCET highlights a reduction in both HIV-1 incidence (the number of new cases) and prevalence (the number of cases in the population) from the beginning to the end of the past decade among a rural Ugandan population. Authors of the study conclude that the results could offer hope for other sub-Saharan countries where the HIV-1 infection rate remains high.
HIV-1 incidence rates in a community are a more accurate measure of epidemic trends than prevalence r
