| HIV patients in care lose more years of life to smoking than to HIV infection Posted: 19 Dec 2012 05:42 AM PST Among HIV patients receiving well-organized care with free access to antiretroviral therapy, those who smoke lose more years of life to smoking than to HIV, according to a new study. The findings highlight the importance of smoking cessation efforts in the long-term, integrated care of patients infected with HIV.  |
| Robotic-assisted radical bladder surgery potentially benefits bladder cancer patients Posted: 19 Dec 2012 05:41 AM PST About 30 percent of the more than 70,000 bladder cancer cases expected in 2012 are muscle invasive. In such cases, radical cystectomy is the preferred treatment. In a pilot trial, a team of investigators assessed the efficacy of open radical cystectomy (ORC) vs. robotic-assisted laparoscopic radical cystectomy (RARC). While there were no significant differences in treatment outcomes, RARC resulted in decreased estimated blood loss and shorter hospital stay compared to ORC.  |
| Fast-acting enzymes with two fingers: Switch protein structurally and dynamically explained Posted: 19 Dec 2012 05:40 AM PST Researchers have uncovered the mechanism that switches off the cell transport regulating proteins.
