IUPUI study: Finding Occam's razor in an era of information overload
How to predict actions and reactions of things invisible to human eye? New study led by physicist Steve Presse, Ph.D., of the School of Science at Indiana University-Purdue University Indianapolis, shows that there may be a preferred strategy for selecting mathematical models with the greatest predictive power. Picking the best model is about sticking to the simplest line of reasoning, according to Presse. His paper explaining his theory is published online this month in Physical Review Letters.

Focusing on faces
Difficulties in social interaction are considered to be one of the behavioral hallmarks of autism spectrum disorders. Previous studies have shown differences in how the brains of autistic individuals process sensory information about faces. Now, a team led Caltech neuroscientist Ralph Adolphs has made the first recordings of the firings of single neurons in the brains of autistic individuals, and has found specific neurons that show reduced processing of the eye region of faces.

Tiny antisense molecules increase 'good cholesterol' levels in obese primates
A strategy developed by Massachusetts General Hospital-based investigators to increase levels of beneficial high-density lipoprotein (HDL) has been shown for the first time to be effective in non-human primates. The approach uses tiny antisense sequences to block the action of microRNAs that would otherwise inhibit a protein required for generation of HDL, the "good cholesterol" that helps remove harmful lipids from the body.

Study is first to explain type of antimalarial drug resistance
This study explores why drugs designed to fight off malaria stop working in some people with the disease. Researchers found genetic and cell biological evidence linking autophagy to resistance to the parasite. Autophagy is the process by which cells remove damaged parts of themselves to restore normal function. In this case, the cell rids itself of the parts damaged by the antimalarial drug.

PTSD raises risk for obesity in women
Women with post-traumatic stress disorder (PTSD) gain weight more rapidly and are more likely to be overweight or obese than women without the disorder, find researchers at Columbia University's Mailman School of Public Health and Harvard School of Public Health. It is the first study to look at the relationship between PTSD and obesity over time. Results appear online in JAMA Psychiatry.

Top hospitals reduce readmissions by preventing complications across all diagnoses
Checking back into the hospital within 30 days of discharge is not only bad news for patients, but also for hospitals, which now face financial penalties for high readmissions. The key to reducing readmissions may be focusing on the whole patient, rather than the specific conditions that caused their hospitalizations, according to a new study by Yale School of Medicine researchers.

Study reveals how variant forms of APOE protein impact risk of Alzheimer's disease
Massachusetts General Hospital investigators have shown that even low levels of the Alzheimer's-associated APOE4 protein can increase the number and density of amyloid brain plaques, related neuronal damage, and the amount of soluble amyloid within the brain in mouse models of the disease. APOE2, a rare variant that has been associated with protection from Alzheimer's of actually reduced A-beta deposition, retention and neurotoxicity, suggesting the potential for gene-therapy-based treatment.

Current practice may over-diagnose vitamin D deficiency
The current "gold standard" test for measuring vitamin D status may not accurately diagnose vitamin D deficiency in black individuals. A team of researchers has found that genetic differences in a vitamin D carrier protein may explain the discrepancy between the prevalence of diagnosed vitamin D deficiency in black Americans and a lack of the usual symptoms of vitamin deficiency.

Neurons in brain's 'face recognition center' respond differently in patients with autism

Discovery of brain activity in severely brain injured patients who 'wake up' with sleep drug
George Melendez has been called a medical miracle. After a near drowning deprived his brain of oxygen, Melendez remained in a fitful, minimally conscious state until his mother, in 2002, decided to give him the sleep aid drug Ambien to quiet his moaning and writhing. The next thing she knew, her son was quietly looking at her and trying to talk. He has been using the drug ever since to maintain awareness, but no one could understand why Ambien led to such an awakening.

Staphylococcus aureus bacteria turns immune system against itself
Around 20 percent of all humans are persistently colonized with Staphylococcus aureus bacteria, a leading cause of skin infections and one of the major sources of hospital-acquired infections, including the antibiotic-resistant strain MRSA. University of Chicago scientists have recently discovered one of the keys to the immense success of S. aureus -- the ability to hijack a primary human immune defense mechanism and use it to destroy white blood cells. The study was published Nov 15 in Science.

New study finds no benefit to selecting dose of blood thinner based on patients' genetic makeup
A new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania has determined that a gene-based method for selecting patients' doses of the popular heart medication warfarin is no better than standardized dosing methods. The study was presented today at the 2013 Scientific Sessions of the American Heart Association and published simultaneously in the New England Journal of Medicine.

Monkeys can point to objects they do not report seeing
Are monkeys, like humans, able to ascertain where objects are located without much more than a sideways glance? Quite likely, says Lau Andersen of the Aarhus University in Denmark, lead author of a study conducted at the Yerkes National Primate Research Center of Emory University, published in Springer's journal Animal Cognition. The study finds that monkeys are able to localize stimuli they do not perceive.

Blood test accurately diagnoses concussion and predicts long term cognitive disability
A new blood biomarker correctly predicted which concussion victims went on to have white matter tract structural damage and persistent cognitive dysfunction following a mild traumatic brain injury. If validated in larger studies, this blood test could identify concussion patients at increased risk for persistent cognitive dysfunction or further brain damage and disability if returning to sports or military activities.
