International reference standards for use of bone turnover markers in clinical studies recommended

An expert working group of the International Osteoporosis Foundation (IOF) and the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) has released a new position paper which reviews the evidence of bone turnover markers (BTMs) in fracture risk prediction and monitoring of osteoporosis therapy. More importantly, it identifies research priorities and recommends that specific markers be used as reference analytes for BTMs in clinical and observational studies.

Turns mortal heart attacks into non-mortal heart attacks -- NIH study

Three weeks of oral resveratrol or Longevinex- ingestion prior to an induced heart attack returned microRNA activity close to their pre-event levels in excised animal hearts. Among thousands of microRNA's studied, just six were attributed to exerting the majority of the gene-switching effects measured in the animal heart study - four microRNA optimally regulated by Longevinex- and two optimally by plain resveratrol.

Biglycan protein offers potential therapy for muscular dystrophy

A novel potential therapy based on a natural human protein significantly slows muscle damage and improves function in mice who have the same genetic mutation as boys with the most common form of muscular dystrophy, according to a paper published online Dec. 27 in the Proceedings of the National Academy of Sciences.

Vitamin D levels of newborns appear to predict their risk of respiratory infections

The vitamin D levels of newborn babies appear to predict their risk of respiratory infections during infancy and the occurrence of wheezing during early childhood, but not the risk of developing asthma. Results of a study in the January 2011 issue of Pediatrics support the theory that widespread vitamin D deficiency contributes to risk of infections.

Amygdala may contribute to rich, varied social life among humans: Scientists

Scientists have discovered that the amygdala, a small almond shaped structure deep within the temporal lobe, is important to a rich and varied social life among humans. The finding was published this week in a new study in Nature Neuroscience and is similar to previous findings in other primate species, which compared the size and complexity of social groups across those species.

Researchers develop microfluidic device to orient hundreds of embryos for research

Researchers have developed a microfluidic device that automatically orients hundreds of fruit fly and other embryos to prepare them for research. The device could facilitate the study of such issues as how organisms develop their complex structures from single cells -- one of the most fascinating aspects of biology.

Good Clostridia prevents development of allergies and inflammatory bowel disease

Scientists at the University of Tokyo have discovered that specific gut-dwelling bacteria control key immune cells that combat allergies and autoimmune diseases. The paper describing these findings was published in today's issue of the journal Science, and technology originating from the work is being advanced by start-up Vedanta Biosciences.

Growth hormone may be hazardous for middle aged and older people

A compound which acts in the opposite way as growth hormone can reverse some of the signs of aging, a research team that includes a Saint Louis University physician has shown. The finding may be counter-intuitive to some older adults who take growth hormone, thinking it will help revitalize them.

Quercetin and resveratrol may play an important role in inflammation and insulin resistance

A study was carried out to examine the extent to which quercetin and trans-resveratrol (RSV) prevented inflammation or insulin resistance in primary cultures of human adipocytes treated with tumor necrosis factor-a (TNF-a)-an inflammatory cytokine elevated in the plasma and adipose tissue of obese, diabetic individuals. Cultures of human adipocytes were pretreated with quercetin and trans-RSV followed by treatment with TNF-a. Subsequently, gene and protein markers of inflammation and insulin resistance were measured.
