NSW Department of Primary Industries (DPI) fisheries scientists are investigating ways to boost the survival rates of fish caught and then released by anglers.

A blood test that detects proteins commonly released by a growing tumor could one day become a useful tool for monitoring the effectiveness of chemotherapy and radiation treatment in people with advanced throat cancer, according to a study published in the June 1, 2007, issue of Clinical Cancer Research. Scientists in the National Institute on Deafness and Other Communication Disorders (NIDCD) and National Cancer Institute (NCI), two of the National Institutes of Health (NIH), in collaboration with researchers of the University of Michigan, found that throat cancer patients who showed a decline in several cancer-related proteins following chemotherapy and radiation treatment were more likely to remain in remission, while those who experienced a large rise over time in those proteins frequently exhibited a return of throat cancer. The findings could help lead to the development of a blood test that enables doctors to detect the recurrence of throat cancer early on, when there is still time to pursue a second line of treatment, such as surgery or drug therapy.

The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators at St. Jude Children's Research Hospital insights into a key strategy cancer cells use to survive and thrive.

University Hospitals Case Medical Center (UHCMC) and Case Western Reserve University School of Medicine are part of a nationwide research study to determine the safety and effectiveness of a new smallpox vaccine geared toward adults ages 18 to 34 who have never been vaccinated against the disease. The study is the first of its type in Northeast Ohio.

Some researchers have hypothesized that the fetus can be exposed to and mount an immune response against allergens to which the mother has been exposed, and this may have an effect on the development of allergic sensitivity (e.g. eczema and asthma) later in an infant’s life. However this hypothesis has remained controversial because of an inability to detect antigen-specific T cells in cord blood. Recently, a newly developed technique known as MHC tetramer staining has facilitated the detection of antigen-specific T cells.

Inflammation in the brain may not be so bad after all when it comes to Alzheimer’s disease.

Molecular & Cell Biology

A University of Pittsburgh School of Medicine research team, collaborating with scientists from Stanford University, have developed a new, smaller gene therapy vector that may be effective in delivering a radioprotective enzyme systemically throughout the body which may spare healthy tissue the long-term consequences of therapeutic irradiation. These results are being presented at the 10th annual meeting of the American Society of Gene Therapy, being held May 30 to June 3 at the Washington State Convention & Trade Center, Seattle.

Aspirin didn’t pan out. Neither did two other potential anti-aging agents. But a synthetic derivative of a pungent desert shrub is now a front- runner in ongoing animal experiments to find out if certain chemicals, known to inhibit inflammation, cancer and other destructive processes, can boost the odds of living longer.
