The prevalence of heart disease and certain risk factors like hypertension, diabetes, and obesity – are increasing throughout Canada found a new study published in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/press/cmaj081629.pdf (www.cmaj.ca). This study, which looked at national data from 1994 to 2005, encompassed people aged 12 years and older sampling from Canadians of all socioeconomic and ethnic groups.

Mathematical modelling can help inform public health policy in outbreaks such as the H1N1 pandemic, write members of the Pandemic Influenza Outbreak Research Modelling Team in Canada in a CMAJ (Canadian Medical Association Journal) article http://www.cmaj.ca/press/cmaj090885.pdf (www.cmaj.ca). These models are useful tools for simulating plausible scenarios, developing control strategies and identifying important areas for immediate research.
CINCINNATI - Scientists have identified a master regulator gene for early embryonic development of the pancreas and other organs, putting researchers closer to coaxing stem cells into pancreatic cells as a possible cure for type1 diabetes.
Researchers at Cincinnati Children's Hospital Medical Center report their findings in the July 21 Developmental Cell.
Early initiation of lifesaving antiretroviral therapies should be the standard of care for all HIV-infected patients, even those in countries with limited medical and financial resources, according to a study led by researchers at Massachusetts General Hospital (MGH) and the Desmond Tutu HIV Centre, University of Cape Town, South Africa.
Cardiovascular disease is increasing in adults under 50 and those of lower socioeconomic status, despite recent trends which show that cardiovascular disease is declining in Canada overall, say researchers at the Peter Munk Cardiac Centre. Untreated cardiovascular disease can lead to heart failure, coronary artery disease and death, and is the most common cause of hospitalization in North America.

Every year, 42,000 Americans are diagnosed with pancreatic cancer. Few live very long, and less than 5% are still alive five years after diagnosis.
There's new hope, though, from the lab of Prof. Yoel Kloog, dean of Tel Aviv University's Faculty of Life Sciences. His drug compound Salirasib has shown positive results against pancreatic cancer and recently passed Phase I/II clinical trials. The drug, given in combination with gemcitabine, the standard drug used to combat pancreatic cancer, almost doubled the life expectancy of those who received it.
AMES, Iowa - Research led by scientists at Iowa State University's Plant Sciences Institute has resulted in a process that will make genetic changes in plant genes much more efficient, practical and safe.
The breakthrough was developed by David Wright, an associate scientist, and Jeffery Townsend, an assistant scientist, and allows targeted genetic manipulations in plant DNA, which could have a huge impact on plant genetic work in the future.
Using snorkelers and SCUBA divers is not the best way to monitor fish populations, if we want to know the evolutionary effects of overfishing.
The fish population in coral reef areas is often assessed by snorkelers or SCUBA divers, but new research shows that these methods may misrepresent the number of fish.
Rice Today's July-September 2009 edition features the development of drought-tolerant rice and other research the International Rice Research Institute (IRRI) and its collaborators are doing to curb the devastating effects of drought.
With some degree of water shortages predicted to affect 15-20 million hectares of irrigated rice within 25 years, smart crop management and even genetically modified rice may also play a role in helping farmers cope with the crisis.
Researchers from the Molecular Immunology group at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have now shown that Beta-Interferon also plays a crucial role during an immune response: without Beta-Interferon immune cells are unable to show "wanted posters" of pathogens to other cells. As a consequence, these cells will not recognize the pathogen and the immune response does not start properly. The group's results have now been published in the current issue of the scientific magazine Journal of Immunology.
Research carried out at the Hebrew University of Jerusalem has resulted in a promising approach to help treat Alzheimer's disease in a significant proportion of the population that suffers from a particularly rapid development of this disease.
Nanoparticles are just billionths of a millimeter in size. Exhibiting novel and often surprising properties, they are finding their way into an endless stream of equally innovative products. In medical therapies, for example, tiny nanovehicles could one day ferry drugs or even genes into cells. So far, the only way of testing these approaches has been to wait for the desired effect to show – the activation of a transported gene inside a cell for example. Under the direction of LMU Munich physicochemist Professor Christoph Bräuchle, a research group cooperating with Dr.
Scientists have a better understanding of what causes an abnormal number of chromosomes in offspring, a condition called aneuploidy that encompasses the most common genetic disorders in humans, such as Down syndrome, and is a leading cause of pregnancy loss.
