Research on patients' immune system may lead to new diagnostic tool for HIV treatment

Mayo Clinic researchers have shown why, in a minority of HIV patients, immune function improves despite a lack of response to standard anti-retroviral treatment. In these cases, researchers say, the virus has lost its ability to kill immune cells. The findings appear in the online journal PLoS Pathogens.

Study finds boosting glucose levels can reduce aggressive behavior

A spoonful of sugar may be enough to cool a hot temper, at least for a short time, according to new research. A study found that people who drank a glass of lemonade sweetened with sugar acted less aggressively toward a stranger a few minutes later than did people who consumed lemonade with a sugar substitute.

Are vitamin D and calcium supplements needed?

The IOM raised the recommended dietary allowance of vitamin D from the amount cited in their last report, released 13 years ago. It said that although 600 international units (IUs) of vitamin D or more each day is sufficient to maintain bone health in majority. But those aged 71 and older may need as much as 800 IUs daily, the IOM experts say. However 1997 recommendations advised 400 IUs per day for people aged 51 to 70 and 600 IUs per day for those over 70.

Research: Mechanical stress plays a vital role in brain function

In the human brain, mechanical stress the amount of pressure applied to a particular area requires a delicate balance. Just the right force keeps neurons together and functioning as a system within the body, and proper nerve function is dependent on this tension.

Prescription rates for controlled medications double for teens, young adults

Adolescents and young adults are most likely to abuse prescription medications. Yet prescription rates for controlled medications, or drugs the Drug Enforcement Administration deems as having the potential for abuse, have nearly doubled for those age groups in the past 14 years, according to a recent study published in Pediatrics. Overall, a controlled medication was prescribed for young adults at approximately one out of every six visits and for young adult by adolescents one out of every nine encounters.

New findings could drive medical advances in genetic disorders that cause infertility

A hormone responsible for the onset of puberty can end up stuck in the wrong part of the body if the nerve pathways responsible for its transport to the brain fail to develop properly, according to research funded by the Biotechnology and Biological Sciences Research Council (BBSRC).

RCSI researchers discover potential new target for diarrhoea associated intestinal diseases

A study by researchers in the Royal College of Surgeons in Ireland (RCSI) has uncovered a potential new target for the treatment of a range of intestinal diseases that are associated with diarrhoea. Current medications are often ineffective and can have serious side effects so this discovery gives hope for the development of new treatments for sufferers of intestinal disease.

Scientists uncover new regulatory mechanism in body's response to eliminate pathogens

A team of scientists from The Scripps Research Institute have uncovered a previously unknown regulatory mechanism in the body's response to eliminate pathogens, such as bacteria and viruses. The findings challenge a long-held dogma in the field of immunology and have potential implications for far-ranging topics from how vaccines should be administered to the origin of autoimmunity.

Research finds alteration in KBTBD13 protein causes nemaline myopathy

Researchers from the Department of Anesthesiology, Uniformed Services University of the Health Sciences (USU), along with research teams from the National Institutes of Health and from Australia, the Netherlands and Spain, have identified a novel gene on chromosome 15q that, when altered, causes nemaline myopathy with cores, a rare inherited muscle disorder. The gene encodes a member of the BTB/Kelch family of proteins.

Study finds abdominal fat as a risk factor for osteoporosis, bone loss in women

For years, it was believed that obese women were at lower risk for developing osteoporosis, and that excess body fat actually protected against bone loss. However, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) found that having too much internal abdominal fat may, in fact, have a damaging effect on bone health.

Study: Mature blood cells communicate with parent stem cells

A new study by researchers at the Walter and Eliza Hall Institute in Melbourne, Australia, has shown that mature blood cells can communicate with, and influence the behaviour of, their stem cell 'parents'.

Ageing reversed in mice: Study

A scientific team at Harvard-affiliated medical centers genetically manipulated mice to age faster. Then they used gene therapy to lengthen telomeres. Telomeres are compounds found at the ends of strands of DNA that are related to age. This lengthening of telomeres reversed age-related problems such as decreased brain function and infertility.
