Newly discovered genetic defect might represent an important risk factor for major depression

A newly discovered genetic defect might represent an important risk factor for major depression, a condition which effects 20 million people in the U.S., according to Duke University Medical Center researchers.

Injectable gel that could speed repair of torn cartilage

In a project that will likely be watched by football players, runners and other athletes, researchers at MIT and Harvard Medical School say they are developing an injectable gel that could speed repair of torn cartilage, a common sports injury, and may help injured athletes return to competition sooner.

Powerful women at a disadvantage in the marriage market because men may prefer to marry less accomplished women

Men are more likely to want to marry women who are their assistants at work rather than their colleagues or bosses, a University of Michigan study finds.

Lupus drug may also be useful in treating psoriasis

A new drug candidate previously shown to reduce harmful side effects of the autoimmune disease lupus also may be useful in treating psoriasis.

Using precise, radioactively labeled genetic probes, researchers study cancer gene activity from outside the body

Using precise, radioactively labeled genetic probes, researchers at Jefferson Medical College have seen cancer gene activity from outside the body in laboratory mice. The probes, which work by attaching to genetic codes copied from an active cancer gene, may someday aid physicians and scientists in cancer detection and in determining the appropriate treatment for a cancer.

Targeted screening of high-risk groups for genital herpes may prevent disease transmission

Identifying asymptomatic people with genital herpes infection through targeted screening of high-risk groups may prevent disease transmission. However, widespread screening of pregnant women is unlikely to reduce the occurrence of herpes in newborns, according to an article in the January 1 issue of Clinical Infectious Diseases, now available online.

Celecoxib may regulate a cell's use of estrogen - might help explain the drug's anticancer properties

Six months of treatment with celecoxib (Celebrex) in women at risk of developing breast cancer results in the reduction of estrogen receptor expression in breast cells, a research team at The University of Texas M. D. Anderson Cancer Center has found.

Short course of radiation therapy following lumpectomy

Fox Chase Cancer Center researchers have presented preliminary results of a clinical trial in which women received a two-week shorter course of radiation therapy than the current standard following a lumpectomy.

Novel anti-rejection protocol should allow major improvement efficacy and quality of life after intestinal and multivisceral transplants

Transplant researchers at the University of Pittsburgh's Thomas E. Starzl Transplantation Institute have dramatically improved intestinal transplant graft survival, and reduced rejection and infection rates by successfully using a novel immunosuppression minimization protocol, thus improving patients' overall quality of life and avoiding the use of several anti-rejection drugs, which can cause serious infections and major complications.

Importance of the phosphatidylinositol 3 kinase (PI3K) pathway to breast cancer development

Because up to 75 percent of breast cancer patients have an abnormality in a specific cell signaling pathway, drugs that target different molecules along that pathway may be especially effective for treating the disease, says a researcher from The University of Texas M. D. Anderson Cancer Center.

Study sheds light on how bacteria persist despite antibiotics

Researchers at the Hebrew University of Jerusalem and Rockefeller University in New York have demonstrated the constant presence of antibiotic-tolerant "persistent cells" within bacteria colonies and have shown, through mathematical modeling, how these cells develop into "normal" cells following their survival of even heavy dosages of antibiotics.

Key molecular signal allows malarial parasites to target human red blood cells

Northwestern University researchers have identified a key molecular "signal" that allows malarial parasites to release virulence proteins inside human red blood cells.

Understanding what causes narcolepsy

Results of a preliminary study in this week’s issue of THE LANCET suggest a step forward in our understanding of the processes behind narcolepsy; there appears to be an underlying autoimmune process for people with a certain genetic profile. Future diagnostic testing of people with this profile should lead to substantial improvements in disease treatment.

Childhood cancer slowly increasing over the past 3 decades

Research from 19 European countries in this week’s issue of THE LANCET documents how childhood cancer, while still rare, has been slowly increasing over the past 3 decades.

A decade of neglect has weakened UNICEF and threatened the future of child survival

As a high-level forum assessing the progress on global health in relation to the millennium development goals concluded in Abuja, Nigeria, last week, the rhetoric of success repeated by those charged with ending the needless deaths of millions of the world's children masks their own deep-seated failure to grapple with critical institutional weaknesses in their own ranks.
