Levels of insulin-related proteins indicate risk of death in some colorectal cancer patients

A pair of proteins may help explain why people with surgically removed colorectal cancer and who are overweight, physically inactive, and follow a Western-pattern diet may have an increased risk of dying of the disease or other causes, Dana-Farber Cancer Institute scientists report in a new study.

Program to deter youth alcohol use also reduces conduct problems, study finds

A University of Georgia program designed to reduce alcohol use, drug use and risky sexual behavior in African-American youth also reduces the likelihood of engaging in conduct problems by up to 74 percent two years later, according to a new study.

Changes in medical terminology confuses patients

The label used to identify a disease - whether it is common language or medical terminology - can influence how serious people think the condition is, according to new research from McMaster University, the second part of a larger study on how people understand and interpret disease.

Lenalidomide safe for elderly patients with chronic lymphocytic leukemia

The oral medication lenalidomide is safe and well-tolerated for elderly patients with chronic lymphocytic leukemia, a group without a well-defined frontline therapy for their disease, researchers from The University of Texas M. D. Anderson Cancer Center reported today at the 50th annual meeting of the American Society of Hematology.

Best obesity treatment

Severely obese patients who have lost significant amounts of weight by changing their diet and exercise habits may be as successful in keeping the weight off long-term as those individuals who lost weight after bariatric surgery, according to a new study published online by the International Journal of Obesity.

Light cigarettes may be more toxic than traditional cigarettes

Typically, tobacco companies market harm-reduction cigarettes as being safer than traditional "full-flavored" brands, leading many smokers to conclude that the use of harm-reduction brands lowers their exposure to toxicants.

Half-dose vaccination in healthy young individuals may be effective in times of vaccine shortage

Individuals younger than 50 who have been previously vaccinated do not appear to have a substantially different immune response to a half-dose of influenza vaccine than to a full dose, according to a report in the December 8/22 issue of Archives of Internal Medicine.

Genetic signature may lead to better treatments for pediatric liver cancers

Scientists have identified a genetic signature that is remarkably effective at predicting the prognosis of an aggressive liver cancer in children.

Networks of interactive genes may predict Leukemia's development

Rather than testing for individual marker genes or proteins, researchers at the University of California, San Diego (UC San Diego) and the Moores UCSD Cancer Center have evidence that groups, or networks, of interactive genes may be more reliable in determining the likelihood that a form of leukemia is fast-moving or slow-growing.

Trial shows safety of pre-transplant expansion of umbilical cord blood stem cells

Taking blood stem cells collected from an umbilical cord into the lab and expanding their number before transplanting them to replace a patient's blood supply is as safe as a standard cord blood transplant, researchers reported at the 50th Annual Meeting of the American Society of Hematology.

An Achilles heel in cancer cells

A protein that shields tumor cells from cell death and exerts resistance to chemotherapy has an Achilles heel, a vulnerability that can be exploited to target and kill the very tumor cells it usually protects, researchers from the University of Illinois at Chicago show in a new study published in the Dec. 9 issue of Cancer Cell.

Alternative splicing proteins prompt heart development

Just as the emotions it represents are dynamic, the heart's development requires dynamic shifts in proteins that prompt alternative spicing, a mechanism that allows a given gene to program the cell to make several proteins, said a group of researchers at Baylor College of Medicine in a report that appears online in the journal Proceedings of the National Academy of Sciences.
