| New screening method for prostate cancer recurrence Posted: 15 May 2015 02:51 PM PDT A common treatment for prostate cancer is a prostatectomy, in which all or part of the prostate gland is removed. Recent studies have shown that this procedure is often over-prescribed. Spatial light interference microscopy has now been used in order to identify patients at higher risk for prostate cancer recurrence, researchers report. |
| Losing weight can reduce risk of death, ventilator use in lung transplant patients Posted: 15 May 2015 02:49 PM PDT Obesity is a complicating factor for many surgical patients. In a recent study, researchers have shown that losing weight can have a positive impact on outcomes for lung transplant patients. |
| Solving streptide from structure to biosynthesis Posted: 15 May 2015 12:57 PM PDT Bacteria speak to one another using peptide signals in a soundless language known as quorum sensing. In a step towards translating bacterial communications, researchers have revealed the structure and biosynthesis of streptide, a peptide involved in the quorum sensing system common to many streptococci. |
| Grass plants can transport infectious prions Posted: 15 May 2015 12:56 PM PDT Grass plants can bind, uptake and transport infectious prions, according to researchers. Prions are the protein-based infectious agents responsible for a group of diseases called transmissible spongiform encephalopathy, which includes bovine spongiform encephalopathy (mad cow disease) in cattle, scrapie in sheep, variant Creutzfeldt-Jakob disease in humans and chronic wasting disease (CWD) in deer, elk and moose. All are fatal brain diseases with incubation periods that last years. |
| Smoking induces early signs of cancer in cheek swabs Posted: 14 May 2015 09:25 AM PDT DNA damage caused by smoking can be detected in cheek swabs, finds research. The study provides evidence that smoking induces a general cancer program that is also present in cancers which aren't usually associated with it -- including breast and gynecological cancers. |
