Childhood obesity risk increased by newly-discovered genetic mutations, says study
Three new genetic variations that increase the risk of obesity are revealed in a new study, published today in the journal Nature Genetics. The authors suggest that if each acted independently, these variants could be responsible for up to 50% of cases of severe obesity.
Study links water pollution with declining male fertility
New research strengthens the link between water pollution and rising male fertility problems. The study, by Brunel University, the Universities of Exeter and Reading and the Centre for Ecology & Hydrology, shows for the first time how a group of testosterone-blocking chemicals is finding its way into UK rivers, affecting wildlife and potentially humans. The research was supported by the Natural Environment Research Council and is now published in the journal Environmental Health Perspectives. more
The heart disease mutation carried by 60 million
Heart disease is the number one killer in the world and India carries more than its share of this burden. Moreover, the problem is set to rise: it is predicted that by 2010 India's population will suffer approximately 60% of the world's heart disease. Today, an international team of 25 scientists from four countries provides a clue to why this is so: 1% of the world's population carries a mutation almost guaranteed to lead to heart problems and most of these come from the Indian subcontinent, where the mutation reaches a frequency of 4%. more
Advance toward first saliva test for Type 2 diabetes
Scientists in Oregon and India are reporting an advance toward developing the first saliva test to diagnose and monitor effectiveness of treatment for Type 2 diabetes. Their report was published in the Jan. 2 issue of ACS' Journal of Proteome Research. The number of cases of that disease (18 million in the United States alone) has doubled during the last 30 years in parallel with the epidemic of obesity. Researchers say their work represents the first comprehensive description of the proteins in the saliva of patients with Type 2 diabetes, also called non-insulin dependent diabetes. more
Bleeding hearts revealed with new scan
Images that for the first time show bleeding inside the heart after people have suffered a heart attack have been captured by scientists, in a new study published today in the journal Radiology.
Important advance in the treatment of cancer and viral infections
Dr. André Veillette, a researcher at the Institut de recherches cliniques de Montréal (IRCM), and his team led by postdoctoral fellow Dr. Mario-Ernesto Cruz-Munoz, will publish in the upcoming issue of the prestigious journal Nature Immunology of Nature Publishing Group. This discovery could have a significant impact on the treatment of cancers and infectious diseases. Current treatments frequently achieve only limited results with these types of diseases, which affect hundreds of thousands of Canadians. more
How Toxoplasma gondii gets noticed
Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host. The report will appear online on January 19th in The Journal of Experimental Medicine. more
