Young people who dress according to the customs of their own ethnic group are less likely to have subsequent mental health problems than those who don't, suggests research in the Journal of Epidemiology and Community Health.
The findings are based on just under 1000 white British and Bangladeshi 11 to 14 year olds in East London schools, where levels of population diversity are among the highest in the UK.
In 2001 the pupils were quizzed about their culture, social life, and health. They were surveyed again two years later, focusing on their mental health.
Insulin-like growth factor (IGF) signaling that helps to regulate mammals growth, metabolism, reproduction and longevity is well documented. Now research published in the open access journal Journal of Biology describes the genetic identification of the first functional insulin-like growth factor binding protein (IGFBP) ortholog in invertebrates.
Now new research published in the open access journal BMC Cell Biology shows that nicotine affects neutrophils, the short-lived white blood cells that defend against infection, by reducing their ability to seek and destroy bacteria.
1. Testosterone Spray Improves Sexual Satisfaction Slightly in Premenopausal Women But So Does Placebo; Editorial Says Treat Women Conventionally
A study that randomized 261 women aged 35 to 46 with self-reported low libido and low serum free testosterone levels to a group that received one of three different doses of a testosterone spray or placebo daily for 16 weeks found that all groups -- including those taking placebo--reported increased frequency of sexually satisfying events (Article, p. 569).
Researchers at UT Southwestern Medical Center have for the first time used drug-treated blood stem cells to repair heart damage in an animal model, results that might point to methods for healing injuries from heart attacks or disease.
In the study, researchers screened about 147,000 molecules to find one that could transform human blood stem cells into a form resembling immature heart cells. When they implanted blood stem cells activated by this compound into injured rodent hearts, the human cells took root and improved the animals’ heart function.
In the April 15th issue of G&D, Dr. Richard Flavell (Yale University) and colleagues identify the c-Cbl protein as a critical repressor of hematopoietic stem cell (HSC) self-renewal. In addition to establishing a key role for protein ubiquitylation in HSC development, this finding posits c-Cbl as a potential target in research into stem cell engineering as well as cell-based leukemia treatments.
Dr. Flavell describes the work as elucidating a novel dimension in our understanding the self-renewal of Hematopoietic stem cells."
CHARLOTTESVILLE, VA (April 14, 2008) What is the best way to determine if you are developing the nations most deadly condition, coronary artery disease (CAD)"
An increasing number of doctors are encouraging patients especially those deemed to be at high-risk for developing CAD to undergo a non-invasive imaging procedure called coronary computed tomography angiography, or coronary CTA, to see if plaque deposits are accumulating in their arteries.
Children who screen positive for amblyopia, reduced vision in one eye, before age 2 appear to have better visual outcomes than those whose vision problems are detected during screenings between ages 2 and 4, according to a report in the April issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Womens perception of their cancer risk appears to vary by race and may affect how likely they are to undergo screenings, particularly for colon cancer, according to a report in the April 14 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
