The effectiveness of screening for prostate cancer

A screening test for prostate cancer that measures prostate-specific antigen (PSA) levels does not improve survival, researchers at the Veterans Affairs (VA) Connecticut Healthcare System and Yale School of Medicine report in the January 9 Archives of Internal Medicine.

New and promising antibody profiling technique to test for non-small cell lung cancer cases

Biomedical scientists have revealed a new and promising antibody profiling technique that provides a high degree of early diagnostic accuracy for non-small cell lung cancer cases.

Nanotechnology and biochemistry provide new way to study T cell signaling

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, combining nanotechnology with biochemistry, have created unique synthetic membranes that, for the first time ever, enable them to directly control signaling activity in living T cells from the immune system. Already their experiments have yielded surprising results.

Study reveals how T cells analyze and react to the signals of infection at the immunological synapse

The immune system is highly complex. The cast of characters alone required to marshal an immune response to a foreign invader can number in the millions as the body's soldiers, T cells, are called into action.

Speed of PSA increase matters more than PSA level

In the largest study of its kind to date, Mayo Clinic researchers report that prostate specific antigen (PSA) kinetics, both velocity and doubling time, can be used to predict disease progression and likelihood of death after radical prostatectomy surgery, suggesting that this could be used to guide treatment decisions.

Zyflamend shows promise in the early treatment of prostate cancer

Data from the Columbia University Department of Urology demonstrates that Zyflamend, a unique herbal extract preparation, suppresses the growth of prostate cancer cells and induces prostate cancer cells to self-destruct via a process called "apoptosis."

Vaccine for a type of blood cancer - follicular lymphoma

A team of researchers has demonstrated the clinical efficacy and benefits of a vaccine for a type of blood cancer, follicular lymphoma, amongst first time relapse patients. Specialists from two University of Navarre centres – the University Hospital and the Research Centre for Applied Medicine (CIMA) - have worked jointly since 2001 on the research.
