Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.
Scientists have shown in literally thousands of studies that the p53 gene deserves its reputation as ?the guardian of the genome.? It calls to action an army of other genes in the setting of varied cell stresses, permitting repair of damaged DNA or promoting cell death when the cell damage is too great. A key net effect of p53?s action is to prevent development of cancerous cells.
Researchers at the University of Pittsburgh School of Medicine?s department of emergency medicine, in collaboration with the Allegheny County Fire Academy, have received a Federal Emergency Management Agency (FEMA) Fire Prevention and Safety grant to conduct a study designed to develop optimal methods of reducing acute cardiovascular risk resulting from exposure to heat stress during fire suppression.
The Fraser-Fort George Museum Society has been awarded a $50,000 grant for the creation of preschool and child care spaces at The Exploration Place, Minister of State for Child Care Linda Reid announced.
A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. The project, conducted jointly in the Schools of Pharmacy, Biomedical Sciences and Human Development, will be featured in the September issue of the Experimental Biology and Medicine.
Restless legs syndrome is a common problem in children 8 years of age and older in the United States and the United Kingdom, according to a new report from an international team of researchers.
Severely obese patients who undergo gastric bypass surgery significantly reduce their risk of death from coronary heart disease, diabetes and cancer, according to research published in the Aug. 23, 2007, issue of the New England Journal of Medicine. The study was led by a team of researchers from the University of Utah School of Medicine and LDS Hospital.
Researchers from the University of Minnesota Medical School and Brain Sciences Center at the Minneapolis VA Medical Center have identified a noninvasive and painless way to diagnose complex brain diseases.
It?s yet another example of how a good thing can go bad: Researchers have found evidence in laboratory studies that ?good? cholesterol, renowned for its ability to protect against heart disease, can undergo detrimental changes in protein composition that make it ?bad? for the heart.
Adult women are more than twice as likely to know how much they weighed in high school as they are to know their current cholesterol number, and only half of women have had their cholesterol tested in the past year, according to the results of a nationwide survey released.
