Prostate Cancer :: Aging gene also protects against prostate cancer development

Cancer researchers have found that a gene that is involved in regulating aging also blocks prostate cancer cell growth. They have shown that the enzyme SIRT1 can block the growth of treatment-resistant prostate cancer cells that overexpress a mutation for the androgen receptor. The scientists hope the newly found connection will aid in better understanding the development of prostate cancer and lead to new drugs against the disease.

Heart Attack :: Heart attack-related depression puts patients at risk for further cardiovascular emergencies

People who experience their first-ever bout of depression after having a heart attack are at greater risk for future heart problems than are patients who either don?t become clinically depressed after the medical emergency or who were depressed even before the incident, new research shows.

Stem Cell :: Signaling for cartilage

Skeletal progenitor cells differentiate into cartilage cells when one master gene actually suppresses the action of another. Skeletons are made of bone and cartilage cells that are differentiated from the same multipotent stem cell, which gives rise to bone, cartilage, fat and fibroblasts.

Weight Loss :: Seniors more at risk for complications from large scale weight-loss surgery

The first large-scale review of weight-loss surgeries performed on older adults suggests bariatric procedures should generally be limited to people younger than age 65, researchers at UT Southwestern Medical Center have found.

Fingerprint technology pioneered in Leicester — To identify the dead

Technology developed for roadside fingerprints using hand-held devices — announced in the media this month — has also been pioneered in identifying the dead, it has been revealed.

Breast Cancer :: Quest for better breast cancer drugs

Breast cancer sufferers could eventually benefit from high-tuned, tailor-made drug treatments that minimize side effects as a result of a joint initiative between computer scientists in Edinburgh and cellular biologists in Japan.

Parkinson’s Disease :: Less risk of Parkinson’s disease with increased cholesterol

Women with higher levels of total cholesterol appear to be at decreased risk for developing Parkinson’s disease, according to a report by researchers in the Netherlands. The study is published in American Journal of Epidemiology, November 2006 issue.

Heart Disease :: Cause of Exercise Intolerance in Heart Failure Patients

A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.

Stem Cell :: Long-term cancer risk follows stem cell transplant recipients

Hematopoietic stem cell transplant (HSCT) recipients face a significant long-term risk for developing a second cancer, particularly if they were older at the time of transplant or received stem cells from a female donor, according to a new study.

Genome:: NHGRI Funds Large-Scale Sequencing Centers for Cancer and Other Medical Purposes

The National Human Genome Research Institute (NHGRI) announced the results of the recent competition for support of its three large-scale sequencing centers, strengthening efforts to use the power of DNA sequencing to unlock the genomic secrets of human diseases.
