Patients with history of skin infection more likely to develop surgical site infections

Johns Hopkins scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat, published in the May issue of Nature Chemical Biology, could eventually help researchers create computers that use cells as tiny circuits.

Flexible sigmoidoscopy reduces deaths due to colorectal cancer

Research conducted at the University of Alabama at Birmingham as part of a national study reveals that flexible sigmoidoscopy — a screening test for colorectal cancer that is less invasive and has fewer side-effects than colonoscopy — reduces deaths due to colorectal cancer.

POZEN presents data from PA32540 Phase 1 gastric acid reduction study at DDW 2012

POZEN Inc., a pharmaceutical company committed to transforming medicine that transforms lives, presented data today from a Phase 1 study that found that the investigational compound, PA32540, provides faster protection compared with delayed-release, enteric-coated omeprazole (40 mg), as measured by mean time to gastric pH.

New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

Hitting the target: IntelliCap provides reliable and accurate regional drug delivery

Medimetrics, recently certified to ISO 13485, has successfully developed the IntelliCap system, specifically designed to target delivery of small molecule drugs and biologics to the gastrointestinal (GI) tract. The technology is capable of achieving controlled release of drugs to specific GI sites in a fast, cost-effective and convenient manner (Shimizu et al., 2008).

Micronutrients, early food supplementation during pregnancy improve survival of newborns

Pregnant women in poor communities in Bangladesh who received multiple micronutrients, including iron and folic acid combined with early food supplementation, had substantially improved survival of their newborns, compared to women in a standard program that included usual food supplementation, according to a study in the May 16 issue of JAMA, a theme issue on Global Health.

HMO critically important in understanding how breastfeeding protects babies

A new University of Illinois study shows that human milk oligosaccharides, or HMO, produce short-chain fatty acids that feed a beneficial microbial population in the infant gut. Not only that, the bacterial composition adjusts as the baby grows older and its needs change.

Energy/Sports drinks damage teeth enamel raising risk of cavities: Study

Researcher Poonam Jain, associate professor and director of community dentistry at the Southern Illinois University School of Dental Medicine said, “The big misconception is that energy drinks and sports drinks are healthier than soda for oral health. This study completely disproves that, because they erode or thin out the enamel of the teeth, leaving them more susceptible to decay and sensitivity.”

Non-invasive imaging technique measures specific brain chemical changes

Alzheimer's disease (AD) is a major neurodegenerative disorder that affects millions of people worldwide. New and accurate techniques for early diagnosis are critical. Pravat K. Mandal, PhD, and his colleagues have developed a completely non-invasive brain imaging technique to measure specific brain chemical changes. This provides a signature of the early stages of AD from the hippocampal region of the brain.
