New therapeutic options for diabetes-related tissue injury
Diabetes mellitus is a metabolic disorder characterized by altered glucose tolerance and impaired
lipid and carbohydrate metabolism, and is associated with a number of complications directly resulting from hyperglycemiainduced
inflammation.

How effective are dental referrals by primary care physicians?
Young children from low-income families experience high levels of tooth decay and face many barriers
to getting dental treatment and preventive services. Because these children usually visit their pediatrician or other primary
care provider far more frequently than a dentist, the primary care medical setting is gaining popularity as a place to
provide preventive dental services.

Mother's vitamin D status during pregnancy will affect her baby's dental health
Low maternal vitamin D levels during pregnancy may affect primary tooth calcification, leading to
enamel defects, which are a risk factor for early-childhood tooth decay.

Cell Transplantation
Stem cells from umbilical cord used in the treatment of hepatic diseases
Researchers of the University of Granada and the University of León (Spain) have proved that human umbilical cord blood mononuclear cells can be an effective alternative to bone marrow. This work, accepted to be published by the journal Cell Transplantation, means a significant advance in regenerative hepatic medicine.

Statins have unexpected effect on pool of powerful brain cells
Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells known as glial progenitor cells that are important to brain health as we age, scientists have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.

Brain noise is a good thing
Canadian scientists have shown that a noisy brain is a healthy brain.
"Brain noise" is a term that has been used by neuroscientists to describe random brain activity that is not important to mental function. Intuitive notions of brain-behavior relationships would suggest that this brain noise quiets down as children mature into adults and become more efficient and consistent in their cognitive processing. But new research from the Rotman Research Institute at Baycrest overturns this notion.

Malaria on the increase in the UK
A huge rise in the numbers of UK residents travelling to malaria endemic areas, combined with a failure to use prevention measures, has significantly increased cases of imported falciparum malaria in the UK over the past 20 years, according to a study published online.

Potential treatment for TB solves puzzle
Scientists have uncovered a new target for the potential treatment of TB, finally resolving a long-running debate about how the bacterial cell wall is built. The research, published in the July issue of Microbiology reveals several molecules that could be developed into drugs to treat tuberculosis. Multi drug-resistant strains of Mycobacterium tuberculosis, the bacterium that causes TB, sparked concern but the recent emergence of extensively drug-resistant strains means the search for new treatments is imperative.

Mimic molecules to protect against plague
Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens. According to research published in the July issue of Microbiology, these molecules make antibiotics more effective and can even be used to protect against other diseases.

Long-term study of middle-aged mice shows
Sirtris, a GlaxoSmithKline company focused on discovering and developing small molecule drugs to treat diseases of aging such as type 2 diabetes, is included among a research team that reported in today's online edition of Cell Metabolism that mice treated at middle-age to the end-of-life with resveratrol showed an overall health improvement, including improved bone health, a reduction in cataracts and cardiovascular dysfunction, and improved balance and motor coordination.

Resveratrol found to improve health, but not longevity in aging mice on standard diet
Scientists have found that the compound resveratrol slows age-related deterioration and functional decline of mice on a standard diet, but does not increase longevity when started at middle age. This study, conducted and supported in part by the National Institute on Aging, part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice.

Red wine ingredient wards off effects of age on heart, bones, eyes and muscle
Large doses of a red wine ingredient can ward off many of the vagaries of aging in mice who begin taking it at midlife, according to a new report published online on July 3 in Cell Metabolism, a Cell Press publication. Those health improvements of the chemical known as resveratrol -- including cardiovascular benefits, greater motor coordination, reduced cataracts and better bone density -- come without necessarily extending the animals' lifespan.

Nanostructures improve bone response to titanium implants
Titanium implants were successfully introduced by P.-I. Brånemark and co-workers in 1969 for the
rehabilitation of edentulous jaws. After 40 years of research and development, titanium is currently the most frequently used
biomaterial in oral implantology, and titanium-based materials are often used to replace lost tissue in several parts of the
body.

New research sheds light on the molecular basis of crib death
Sudden infant death syndrome is a condition that unexpectedly and unexplainably takes the lives of seemingly healthy babies aged between a month and a year. Now researchers of the European Molecular Biology Laboratory in Monterotondo, Italy, have developed a mouse model of the so-called crib or cot death. The model, published in this week's issue of Science, reveals that an imbalance of the neuronal signal serotonin in the brain stem is causes sudden death in mice.
