U.S. has seen widespread adoption of robot-assisted cancer surgery to remove the prostate — ScienceDaily

In 2001, surgeons began using robotic technologies in operations to remove the prostate. To examine trends in the use of such robotic-assisted radical prostatectomy (RARP) procedures for prostate cancer patients, Steven Chang, MD, MS, of Harvard Medical School, the Dana-Farber Cancer Institute, and Brigham and Women’s Hospital, led a team that analyzed 489,369 men who underwent non-RARP (i.e., open or laparoscopic radical prostatectomy) or RARP in the United States from 2003 to 2010. During the study period, RARP adoption (defined as performing more than 50 percent of annual radical prostatectomies with the robotic approach) increased from 0.7 percent to 42 percent of surgeons performing radical prostatectomies. Surgeons who performed at least 25 radical prostatectomies each year were more likely to adopt RARP…

Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health

Hydrogen sulfide, or H2S, is normally toxic, but in small amounts it plays a role in cardiovascular health. In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says chemist Alexander R. Lippert, Southern Methodist University, Dallas…

Tumors disable immune cells by using up sugar

The scientists found that when they kept sugar away from critical immune cells called T cells, the cells no longer produced interferon gamma, an inflammatory compound important for fighting tumors and some kinds of infection. "T cells can get into tumors, but unfortunately they are often ineffective at killing the cancer cells," said Erika Pearce, PhD, assistant professor of pathology and immunology. …
