DNA sequencing uncovers latent risk for developing cystic fibrosis Posted: 25 Jul 2016 12:11 PM PDT All babies with a known mutation for cystic fibrosis (CF) and second mutation called the 5T allele should receive additional screening in order to better predict the risk of developing CF later in life, new research shows.

Sub-set of stem cells found to minimize risks when used to treat damaged hearts Posted: 25 Jul 2016 12:11 PM PDT Scientists use mathematical modeling to simulate human mesenchymal stem cell delivery to a damaged heart and found that using one sub-set of these stem cells minimizes the risks associated with this therapy. The study represents a development in novel strategies to repair and regenerate heart muscle and could improve stem cell treatments for heart attack patients.

Promising new drug could help treat spinal muscular atrophy Posted: 25 Jul 2016 10:53 AM PDT Approximately one out of every 40 individuals in the United States is a carrier of the gene responsible for spinal muscular atrophy, a neurodegenerative disease that causes muscles to weaken. Researchers have developed a new molecule in April 2014 that was found to be highly effective in animal models. Now, testing of that compound is leading to a better prognosis for mice with the disease and the possibility of potential drugs.

Protein in breast milk reduces infection risk in premature infants Posted: 25 Jul 2016 10:37 AM PDT Full-term babies receive natural protection from their mothers that helps them fight off dangerous infections. However, babies born prematurely lack protective intestinal bacteria and often are unable to be nursed, causing their infection-fighting capabilities to be underdeveloped. Now, researchers have found that a manufactured form of lactoferrin, a naturally occurring protein in breast milk, can help protect premature infants from a type of staph infection.

DNA analyses reveal genetic identities of world's first farmers Posted: 25 Jul 2016 10:37 AM PDT Conducting the first large-scale, genome-wide analyses of ancient human remains from the Near East, an international team of scientists has illuminated the genetic identities and population dynamics of the world's first farmers.

Using tau imaging as diagnostic marker for Alzheimer disease Posted: 25 Jul 2016 09:17 AM PDT The accumulation of ?-Amyloid and tau proteins in the brain is hallmark pathology for Alzheimer disease. Recently developed positron emission tomography (PET) tracers, including [18F]-AV-1451, bind to tau in neurofibrillary tangles in the brain. So, could tau imaging become a diagnostic marker for Alzheimer disease and provide insights into the pathophysiology of the neurodegenerative disorder that destroys brain cells?

Racial differences in inpatient procedures after stroke Posted: 25 Jul 2016 09:17 AM PDT Inpatient procedures are an integral part of routine stroke care. Some procedures have a curative intent to heal the patient, while others are life-sustaining procedures. A new study has found that minority patients were more likely to undergo the four life-sustaining procedures than white patients. However, the odds of undergoing IVT and carotid revascularization - those procedures with curative intent - were lower for minority patients, according to the results.

Are primary stroke centers associated with lower fatality? Posted: 25 Jul 2016 09:17 AM PDT Does a long travel time to a primary stroke center (PSC) offset the potential benefits of this specialized care?

New study to help people withdraw from inappropriate long-term antidepressant treatment Posted: 25 Jul 2016 06:01 AM PDT One in 10 adults are being given antidepressants each year, but up to 50 per cent of patients could be given an alternative treatment, a new article suggests.

3 in 10 women able to conceive naturally after infertility treatment Posted: 25 Jul 2016 06:01 AM PDT Women who have IVF/ICSI infertility treatments have a 29% chance of conceiving naturally within six years of the cessation of treatments, a new report suggests.

Parenchymal enhancement in breast tissue is not an indicator for increased cancer risk Posted: 25 Jul 2016 06:01 AM PDT Women with a certain gene mutation are among the high-risk patients for breast cancer. With a magnetic resonance tomography (MRT) it is possible to detect tissue with measurable active blood supply which indicates an increased breast cancer risk. Now experts are now exploring whether tissue with active blood supply visible with MRT could indicate a grater risk in those patients without gene mutation. The result: so-called "background parenchymal enhancement" of the breast in these women is not associated with breast cancer.

Painless and inexpensive microneedle system to monitor drugs Posted: 25 Jul 2016 06:00 AM PDT Researchers have created a microneedle drug monitoring system that could one day replace costly, invasive blood draws and improve patient comfort.
