Study finds previously unrecognized way that degradation can occur in silicone-urethane plastics

Scientists have discovered a previously unrecognized way that degradation can occur in silicone-urethane plastics that are often considered for use in medical devices. Their study, published in ACS' journal Macromolecules, could have implications for device manufacturers considering use of these plastics in the design of some implantable devices, including cardiac defibrillation leads.

Study reveals dual role for Norrin/Frizzled-4 protein pair

Working with mice, Johns Hopkins researchers have shed light on the activity of a protein pair found in cells that form the walls of blood vessels in the brain and retina, experiments that could lead to therapeutic control of the blood-brain barrier and of blood vessel growth in the eye.

Scientists identify novel mechanism by which ketogenic diet could delay effects of aging

Scientists at the Gladstone Institutes have identified a novel mechanism by which a type of low-carb, low-calorie diet-called a "ketogenic diet"-could delay the effects of aging. This fundamental discovery reveals how such a diet could slow the aging process and may one day allow scientists to better treat or prevent age-related diseases, including heart disease, Alzheimer's disease and many forms of cancer.

New technology allows noninvasive SpHb assessments for children undergoing brain surgery

For children undergoing brain surgery, a new technology allows noninvasive, continuous monitoring of blood hemoglobin levels, according to a study in the December issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Dietary fish oil supplements could help heal bedsores

Chock-full of Omega-3 fatty acids and antioxidants, fish oil can help lower blood pressure, reduce inflammation in the skin and joints, and promote healthy fetal development. Now a Tel Aviv University researcher has found that it has a positive effect on bedsores, too.

Sputum color guides antibiotic treatment in COPD

Withholding antibiotic treatment from hospitalized chronic obstructive lung disease patients with nonpurulent sputum does not negatively affect outcomes, a pilot study shows.

Linagliptin may reduce brain damage following stroke in type 2 diabetic patients

In a study in mice, scientists at Karolinska Institutet in Sweden have discovered a new potential therapy that may reduce brain damage following stroke in type 2 diabetic patients. The suggested drug is already approved for the treatment of type 2 diabetes. However, the scientists hope that this new results, presented in the scientific journal Diabetes, also opens up the possibility to decrease brain injury after stroke in other patient groups with a high stroke risk.

Obstructive sleep apnea affects women more severely than men

Women suffering from sleep apnea have, on the whole, a higher degree of brain damage than men with the disorder, according to a first-of-its-kind study conducted by researchers at the UCLA School of Nursing.

Researchers study antimicrobial peptides in fish gills to find solution for blocking human infections

Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses against waterborne pathogens, including antimicrobial peptides located in their gills. Undergraduate researchers at Worcester Polytechnic Institute are studying the biology and the mechanics of one of those peptides with the hope they can use that knowledge to create engineered surfaces that kill bacteria responsible for foodborne illnesses and hospital-acquired infections.

Studies demonstrate effectiveness of Nonin's EQUANOX Advance Model 7600 Oximetry System

Nonin Medical, Inc. announced today the publication of two separate studies that demonstrate the clinical efficacy of the company's EQUANOX Model 7600 Cerebral and Somatic Oximetry System in adult and pediatric patients.

DFG to establish 11 Collaborative Research Centres in Jan 2013

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven Collaborative Research Centres (CRCs) as of 1 January 2013. This was decided by the responsible Grants Committee during its fall session in Bonn.

Scientists define key underlying process implicated in multiple sclerosis

Scientists at the Gladstone Institutes have defined for the first time a key underlying process implicated in multiple sclerosis (MS)-a disease that causes progressive and irreversible damage to nerve cells in the brain and spinal cord. This discovery offers new hope for the millions who suffer from this debilitating disease for which there is no cure.

New paper describes MCUR1 protein and its function

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

microRNA-223 molecule plays a surprising role in protecting brain cells from stroke effects

A small molecule known to regulate white blood cells has a surprising second role in protecting brain cells from the deleterious effects of stroke, Johns Hopkins researchers report. The molecule, microRNA-223, affects how cells respond to the temporary loss of blood supply brought on by stroke - and thus the cells' likelihood of suffering permanent damage.

Tadalafil may offer therapeutic strategy in patients with Becker muscular dystrophy

Cedars-Sinai Heart Institute researchers have found in an initial clinical trial that a drug typically prescribed for erectile dysfunction or pulmonary hypertension restores blood flow to oxygen-starved muscles in patients with a type of muscular dystrophy that affects males, typically starting in childhood or adolescence.

Engineered ICCs can improve pancreatic islet transplantation and cure diabetes mellitus

A study published in the current issue of Cell Transplantation, now freely available on-line, reports that a team of researchers in South Korea have successfully engineered islet cell clusters (ICCs) that will improve pancreatic islet transplantation and offer promise for curing diabetes mellitus.

Carnosic acid promotes eye health

Herbs widely used throughout history in Asian and early European cultures have received renewed attention by Western medicine in recent years. Scientists are now isolating the active compounds in many medicinal herbs and documenting their antioxidant and anti-inflammatory activities. In a study published in the journal Investigative Ophthalmology & Visual Science, Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) report that carnosic acid, a component of the herb rosemary, promotes eye health.

High-resolution real-time images show how nerves may be damaged during earliest stages of MS

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.

New investigational procedure may prolong life for patients with severe COPD

November is Chronic Obstructive Pulmonary Disease (COPD) Awareness Month. COPD, also known as emphysema, is the third leading cause of death in the United States, only behind heart disease and cancer. Right now, the only studied interventions that prolong life for patients with severe COPD are supplemental oxygen in people with low oxygen levels and lung volume reduction surgery (LVRS) in appropriately selected individuals.

ABCA3 gene associated with respiratory distress syndrome in babies

Some infants are more susceptible to potentially life-threatening breathing problems after birth, and rare, inherited DNA differences may explain why, according to research at Washington University School of Medicine in St. Louis.
