Mott Children's Hospital and Johns Hopkins University. http://medicalxpress.com/news/2013-06-primary-office-hours-kids-emergency.html Pediatrics Wed, 19 Jun 2013 12:47:01 EST news290864815 A decade-long JDRF-funded study led by the Institute of Diabetes Research in Helmholtz Zentrum München, Germany, is providing a deeper understanding of the link between autoantibodies and the risk of developing type 1 diabetes (T1D), highlighting the importance of pre-diabetes research into possible preventions for the disease. The study, "Seroconversion to Multiple Islet Autoantibodies and Risk of Progression to Diabetes in Children," was published today in The Journal of the American Medical Association. http://medicalxpress.com/news/2013-06-islet-autoantibodies-young-children-early.html Diabetes Wed, 19 Jun 2013 12:09:05 EST news290862537 Researchers at Moffitt Cancer Center and colleagues at Louisiana State University have developed a method for identifying aggressive prostate cancers that require immediate therapy. It relies on understanding the genetic interaction between single nucleotide polymorphisms (SNPs). The goal is to better predict a prostate cancer's aggressiveness to avoid unnecessary radical treatment. http://medicalxpress.com/news/2013-06-genetic-variants-aggressive-prostate-cancers.html Cancer Wed, 19 Jun 2013 12:08:44 EST news290862517 Insulin is the most potent physiological anabolic agent for tissue-building and energy storage, promoting the storage and synthesis of lipids, protein and carbohydrates, and inhibiting their breakdown and release into the circulatory system. It also plays a major role in stimulating glucose entry into muscle tissue, where the glucose is metabolized and removed from the blood following meals. But gaps exist in understanding the precise molecular mechanisms by which insulin regulates glucose uptake in fat and muscle cells. http://medicalxpress.com/news/2013-06-breakthrough-essential-molecule-reveals-important.html Medical research Wed, 19 Jun 2013 12:08:15 EST news290862489 Oscar Wilde called memory "the diary that we all carry about with us."

Now stop thinking. You have just put your brain into what neuroscientists call its resting state. What the brain is doing when an individual is not focused on the outside world has become the focus of considerable research in recent years. One of the potential benefits of these studies could be definitive diagnoses of mental health disorders ranging from bipolar to post-traumatic stress disorders. http://medicalxpress.com/news/2013-06-validating-brain-resting-state.html Neuroscience Wed, 19 Jun 2013 12:00:04 EST news290855785 In fall 2012, the European Medicines Agency (EMA) approved the modified adeno-associated virus AAV-LPL S447X as the first ever gene therapy for clinical use in the Western world. uniQure, a Dutch biotech company, had developed AAV-LPL S447X for the treatment of a rare inherited metabolic disease called lipoprotein lipase deficiency (LPLD) which affects approximately one or two out of one million people. The disease causes severe, life-threatening inflammations of the pancreas. Afflicted individuals carry a defect in the gene coding for the lipoprotein lipase enzyme which is necessary for breakdown of fatty acids. AAV-LPLS447X shall be used as a viral vector to deliver an intact gene copy to affected cells. http://medicalxpress.com/news/2013-06-danger-cancer-gene-therapy-virus.html Genetics Wed, 19 Jun 2013 11:24:26 EST news290859857 New data, published today in Menopause International, suggests that post-menopausal women in Britain are experiencing less sex, and less satisfying sex compared to their European and North American counterparts1, because they are considerably less likely to access appropriate treatment for a common, taboo condition called vaginal atrophy1. http://medicalxpress.com/news/2013-06-british-women-percent-likley-recieve.html Health Wed, 19 Jun 2013 11:23:07 EST news290859776 The motor neuron disease Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, progresses in a stepwise, sequential pattern which can be classified into four distinct stages, report pathologists with the Perelman School of Medicine at the University of Pennsylvania in the Annals of Neurology. http://medicalxpress.com/news/2013-06-staging-als-potential-tracks-disease.html Neuroscience Wed, 19 Jun 2013 10:58:16 EST news290858240 Diapocynin, a synthetic molecule derived from a naturally occurring compound (apocynin), has been found to protect neurobehavioral function in mice with Parkinson's Disease symptoms by preventing deficits in motor coordination. http://medicalxpress.com/news/2013-06-antioxidant-parkinson-disease.html Parkinson's & Movement disorders Wed, 19 Jun 2013 10:38:15 EST news290857075 Thanks to vaccination, polio has been pushed to the brink of extinction – but can we finish the job?

Furthermore, even though elderly patients are occasionally included in clinical trials, those elderly patients who are eventually included are mostly 'healthy' (fit) elderly patients. Thus, the broader elderly patient population is not well represented in clinical trials. The EORTC Cancer in the Elderly Task Force is now starting a new phase 2 trial in precisely this group of patients: EORTC 75111 – 10114 for non-fit elderly patients with HER-2 positive metastatic breast cancer. http://medicalxpress.com/news/2013-06-eortc-elderly-patients-her-positive.html Cancer Wed, 19 Jun 2013 10:00:15 EST news290854794 For years, Alzheimer's researchers have focused on two proteins that accumulate in the brains of people with Alzheimer's and may contribute to the disease: plaques made up of the protein amyloid-beta, and tangles of another protein, called tau. http://medicalxpress.com/news/2013-06-alzheimer-interaction-proteins-brain.html Alzheimer's disease & dementia Wed, 19 Jun 2013 09:25:13 EST news290852704 The age at which many children in the U.S. take their first sip of alcohol is surprisingly young, finds a new study in the Journal of Adolescent Health. http://medicalxpress.com/news/2013-06-alcohol-grade.html Health Wed, 19 Jun 2013 09:20:01 EST news290851533 For years, the mantra of neurologists treating stroke victims has been "time equals brain."

As unlikely as it may seem, those compounds are sparking optimism as potential treatments for ovarian and breast cancers driven by a mutation in BRCA, a gene that made headlines when actress Angelina Jolie revealed she carries the mutation. The compounds, termed PARP inhibitors, are the topic of the cover story in the current edition of Chemical & Engineering News.
