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.

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

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

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.
