Heart specialists increasingly fear that the lack of women in cardiology

Heart specialists increasingly fear that the lack of women in cardiology, despite growing numbers of female medical students, will bring down standards of practice and research in the specialty, reveals a British Cardiac Society report.

Clot-dissolving drugs such as tPA may help detect potentially deadly leg clots

A possible diagnostic use for clot-dissolving drugs such as tPA has been found by Medical College of Georgia researchers working to improve a test that identifies potentially deadly blood clots in the legs.

Older heart transplant recipients fare just as well as their younger counterparts

Policy makers who use age as a discriminating factor in determining eligibility for heart transplant surgery may want to reconsider their rules in the light of new research at the University of Alberta.

Medical expenditures for morbidly obese adults far outweighs that for normal-weight adults

Health-care costs for morbidly obese adults are nearly twice those of people considered to be of normal weight, says a study led by University of Cincinnati (UC) researchers.

Paradox suggests reasons why COX-2 inhibitors hurt and help

Laboratory studies at Johns Hopkins have revealed that certain products of the enzymes COX-1 and COX-2 can both protect and damage the brain. The findings, published in the February 2005 issue of the Journal of Neurochemistry, offer tantalizing clues to why drugs like Vioxx and Celebrex, which block COX-2, can ease arthritis but potentially harm the heart and brain.

Potential cause of rapid kidney stone formation in astronauts on space travels

NASA researchers announce a potential cause of rapid kidney stone formation in astronauts on space travels. The authors of a study published in Kidney International call for a "Major Initiative" to investigate nanobacteria.

Speed dating offers researchers a systematic look at the genuine behavior of people selecting mates

It seems that the heart wants what the heart wants -- and it can figure it out fairly quickly, according to evolutionary psychologists at the University of Pennsylvania. The researchers studied dating data from 10,526 anonymous participants of HurryDate, a company that organizes "speed dating" sessions, and found rare behavioral data on how people genuinely act in dating situations.

Why estrogenic hormones produce unintended results in women

New research is shedding light on why estrogenic hormones produce unintended results in women, giving hope to the idea that new drugs might reach their targets and work more effectively. Ultimately it could mean that postmenopausal women would know that hormone-replacement therapy would have only its intended result.

First evidence of cardiac progenitor cells

The first evidence of cardiac progenitor cells – rare, specialized stem cells located in the newborn heart of rats, mice and humans – has been shown by researchers at the University of California, San Diego (UCSD) School of Medicine.
