article
The Banting Medal for Scientific Achievement Award is the American Diabetes Association's highest scientific award and honors an individual who has made significant, long-term contributions to the understanding of diabetes, its treatment, and/or prevention. The award is named after Nobel Prize winner Sir Frederick Banting, who codiscovered insulin treatment for diabetes. More

Biochemist unlocks gene's role in breast-tumor growth
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New research led by McGill Biochemist Dr. William Muller helps explain why breast-milk cells lose their structure, causing them to clump up in strange ways and sometimes become cancer tumors. With the support of Chen Ling and Dongmei Zuo at McGill's Goodman Cancer Centre, Muller has discovered how one particular gene regulates epithelial cells — cells that normally form in sheets and are polarized to enable the transport of molecules in a single direction.

Gene linked to obesity and higher Alzheimer's risk
Reuters via Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A variant of an obesity gene carried by more than a third of the U.S. population also reduces brain volume, raising carriers' risk of Alzheimer's disease, U.S. researchers said. People with a specific variant of the fat mass and obesity gene, or FTO gene, have brain deficits that could make them more vulnerable to the mind-robbing disease. More

The novel H1N1 outbreak: Lessons learned
Laboratory Medicine via Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
For the Israel Davidson Laboratory of Mount Sinai Hospital, Chicago, the spring 2009 outbreak of H1N1 could have been a catastrophic epidemic. While it was not catastrophic, the lab did process 16 percent of the positive cases of H1N1 in Cook County—the Illinois county with the largest number of confirmed cases, in the state with the largest number of confirmed cases. The spring outbreak provided valuable lessons for the Sinai lab and other health center laboratories. Long delays for confirmation made cohorting patients difficult, whereas if available, rapid, definitive testing for H1N1 would facilitate patient cohorting and allow workers with non-influenza infections to return to work sooner.

Dairy products linked to high prostate cancer risk

The Food and Drug Administration has reportedly approved a therapeutic vaccine indicated to treat advanced prostate cancer, according to media reports. This vaccine known as Provenge doesn't prevent cancer. It gives patients with advanced prostate cancer four more months to live, said Philip Kantoff of Boston's Dana-Farber Cancer Institute who conducted a trial of 512 men. More

New blood screening method sheds light on cell membranes and disease
Medill Reports Chicago    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A novel way of imaging red blood cells could provide insights into how these oxygen-carrying cells navigate the body's maze of blood vessels. The payoff may promise better screening for blood cell related diseases such as malaria and sickle-cell. Researchers published their findings this month in the Proceedings of the National Academy of Sciences. More

Anemia harder to treat in black children with kidney disease
HealthDay News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Even when given the same medical treatment, black children with chronic kidney disease have more severe anemia than white patients, a new U.S. study has found. Anemia, marked by low levels of red blood cells, is diagnosed by measuring levels of the protein hemoglobin, which carries oxygen in and out of red blood cells. In general, hemoglobin levels below 11 grams per deciliter of blood indicate anemia. More

Study: Natural compound speeds bone growth
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
They found the protein sends a signal that activates bone stem cells to make new bone, and said the finding could also improve bone grafts. While the findings were tested in mice, humans and mice have the same biology in this area. "We believe our strategy has the therapeutic potential to accelerate and improve tissue healing in a variety of contexts," said Dr. Jill Helms of Stanford University in California, who led the study.
