Insulin resistance occurs in the brains of people with Alzheimer's

Insulin resistance in the brain precedes and contributes to cognitive decline above and beyond other known causes of Alzheimer's disease, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Insulin is an important hormone in many bodily functions, including the health of brain cells.

S. gordonii may trigger infective endocarditis

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week.

Metformin can have protective effects on the heart

The widely used diabetes medicine metformin can have protective effects on the heart, reveals a new study conducted at the Sahlgrenska Academy, at the University of Gothenburg, Sweden.

New IVIG trial can reduce OCD symptoms in children with PANDAS

Criteria for a broadened syndrome of acute onset obsessive compulsive disorder (OCD) have been proposed by a National Institutes of Health scientist and her colleagues. The syndrome, Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), includes children and teens that suddenly develop on-again/off-again OCD symptoms or abnormal eating behaviors, along with other psychiatric symptoms - without any known cause.

New method for measurement of aggregated beta-amyloid in AD

An international team of researchers have developed a new method for measurement of aggregated beta-amyloid - a protein complex believed to cause major nerve cell damage and dysfunction in Alzheimer's disease. The new method might facilitate diagnosis and detection as well as development of drugs directed against aggregated beta-amyloid.

GenVec announces data from respiratory syncytial virus vaccine program

GenVec, Inc. (Nasdaq: GNVC) announced today that data were presented on GenVec's respiratory syncytial virus (RSV) vaccine program at the "Keystone Symposium on Viral Immunity and Host Gene Influence", which is taking place in Keystone, Colorado from March 21-26, 2012.

Researchers identify gene that influences how we respond to flu infection

A genetic finding could help explain why influenza becomes a life-threating disease to some people while it has only mild effects in others. New research led by the Wellcome Trust Sanger Institute has identified for the first time a human gene that influences how we respond to influenza infection.

MicroRNAs linked to imminent threat of heart attack

Researchers at the Intermountain Medical Center Heart Institute have, for the first time ever, made a connection between tiny genetic molecules called microRNAs and the imminent threat of a heart attack, according to a new study.

Researchers pinpoint new mechanism that potently activates T-cells in leprosy

UCLA researchers pinpointed a new mechanism that potently activates T-cells, the group of white blood cells that play a major role in fighting infections.

Fruit flies too get kidney stones

Research on kidney stones in fruit flies may hold the key to developing a treatment that could someday stop the formation of kidney stones in humans, a team from Mayo Clinic and the University of Glasgow found.

Testosterone may play a role in treatment of triple negative breast cancer

Could blocking a testosterone receptor lead to a new way to treat an aggressive form of breast cancer? That's a question researchers at Mayo Clinic in Arizona and the Translational Genomics Research Institute (TGen) are exploring. Preliminary results of a Mayo Clinic - TGen collaborative study shows the testosterone receptor may be a potential target to attack in treating triple negative breast cancer (TNBC).

Fraunhofer FIT software rapidly analyzes complex biological processes

At Analytica 2012, Fraunhofer FIT presents software that supports the search for new active pharmaceutical ingredients of cancer drugs. Through a high degree of parallelization, the software can analyze complex biological processes very fast, even with large amounts of data.

Deficiency of Mitofusin 2 protein leads to insulin resistance, glucose intolerance

The study shows that the lack of Mitofusin 2 in mice produces insulin resistance and glucose intolerance, the main causes of diabetes.

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Mendelian randomization not the 'Holy Grail' in evaluating alcohol intake with cognitive function

Many observational cohort studies have shown that moderate alcohol use is associated with better cognitive function. However, since such studies are vulnerable to residual confounding by other lifestyle and physiologic factors, the authors conducted a Mendelian randomization study, using aldehyde dehydrogenase 2 (ALDH2) genotype (AA, GA, or GG) as an instrumental variable in 2-stage least squares analysis.

Genetic marker identifies tumors unable to repair DNA damage by platinum agents

Scientists from Brigham and Women's Hospital and Dana-Farber Cancer Institute and their colleagues have found a genetic marker that predicts which aggressive "triple negative" breast cancers and certain ovarian cancers will likely respond to platinum-based chemotherapies.

Treatment with aromatase inhibitors enables some women to have lumpectomy

Preoperative treatment with aromatase inhibitors increases the likelihood that postmenopausal women with estrogen receptor-positive breast cancer will be able to have breast-conserving surgery rather than a mastectomy, according to the results of a national clinical trial presented today at the Society of Surgical Oncology annual meeting in Orlando, Fla.

Max Planck researchers obtain somatic stem cells from fully differentiated somatic cells

Breaking new ground, scientists at the Max Planck Institute for Molecular Biomedicine in M-nster, Germany, have succeeded in obtaining somatic stem cells from fully differentiated somatic cells. Stem cell researcher Hans Sch-ler and his team took skin cells from mice and, using a unique combination of growth factors while ensuring appropriate culturing conditions, have managed to induce the cells' differentiation into neuronal somatic stem cells.

Obese children with PNPLA3 and GCKR genetic variants more susceptible to fatty liver disease

New research found the genetic variant Patatin-like phospholipase domain containing protein-3 (PNPLA3) acting in conjunction with the glucokinase regulatory protein (GCKR) is associated with increased susceptibility to fatty liver disease in obese children.
