Testosterone doping tests in sport ignore ethnic differences in hormone activity

Current steroid (testosterone) doping tests should be scrapped for international sport, because they ignore vital ethnic differences in hormone activity, suggests research published ahead of print in the British Journal of Sports Medicine.

New test successfully identifies arrhythmogenic right ventricular cardiomyopathy

A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC.) Reported in the March 12 issue of The New England Journal of Medicine ( NEJM ), the new findings offer the possibility of a highly sensitive and specific means of identifying this life- threatening condition at an early stage, when it can be treated with by implanting a cardiac defibrillator.

Bioinformatics sheds light on evolutionary origin of Rickettsia virulence genes

Scientists from the Virginia Bioinformatics Institute (VBI) at Virginia Tech, the University of Maryland School of Medicine, and the University of Louisville have revealed that genes for a specific type of molecular secretion system in Rickettsia, a structure that is linked in many cases to virulence, have been conserved over many years of evolution.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

Perinatal environment influences aggression in children

It's a well-documented fact that children from zero to two can be spontaneously aggressive and that boys can be among the worse culprits.

BRCA gene mutations influence a women's views of preventive mastectomy

Women whose cells harbor harmful mutations in the BRCA genes are likely to view preventive mastectomy as the best way to reduce their risk and fears of developing breast cancer, despite other, less drastic options available.

Children of older fathers perform less well in a range of cognitive tests during infancy and early childhood

In contrast, the study finds that children with older mothers gain higher scores in the same tests - designed to measure the ability to think and reason, including concentration, learning, memory, speaking and reading skills.

Tools for more accurate dosage of drugs against HIV/AIDS and malaria

A doctoral thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden, shows that it is possible to describe and quantify the relationships between dose, concentration and effectiveness of several drugs against HIV/AIDS and malaria.
