Gaze Shifting Delay Has Potential To Diagnose Autism At 7 Months
Date: Mar-27-2013At 7 months of age, children who are later diagnosed with autism take a split second longer to shift their gaze during a task measuring eye movements and visual attention than do typically developing infants of the same age, according to researchers supported by the National Institutes of Health. The difference between the groups' test results was 25 to 50 milliseconds on average, the researchers found, too brief to be detected in social interactions with an infant...
New Discovery Likely To Boost Nerve Regeneration Research And Therapy
Date: Mar-27-2013A new mechanism for guiding the growth of nerves that involves cell-death machinery has been found by scientists at the University of Nevada, Reno that may bring advances in neurological medicine and research. The team obtained the evidence in studies of fruit flies and reported their discovery in an article published in the prestigious science publication Cell Reports...
Organisation Trumps Size In Primate Brain Evolution
Date: Mar-27-2013The evolution of anthropoid primates, including monkeys, apes and humans, over the past 40 million years was largely driven by brain reorganization, and not brain size, according to new research from UCL. The study, which is published in Proceedings of the Royal Society B, found that around three quarters of differences between the brains of species of monkeys and apes are due to internal reorganization that is independent of size, dispelling the idea that variation in size is the primary factor characterising anthropoid primate brain evolution...
Design Of Small Molecule To Disrupt Cancer-Causing Protein Will Likely Impact Breast, Lung, Prostate Cancer
Date: Mar-27-2013Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have developed a small molecule that inhibits STAT3, a protein that causes cancer. This development could impact the treatment of several tumor types, including breast, lung, prostate and others that depend on STAT3 for survival. The study appeared in a recent online issue of Cancer Research, a publication of the American Association for Cancer Research. "STAT3 has been associated with poor prognosis and resistance to chemotherapy in patients with cancer," explained Said M. Sebti, Ph.D...
Type 1 Diabetes Risk Linked To Low Pathogen Exposure In Early Life
Date: Mar-26-2013Countries with lower death rates from infectious diseases have higher incidences of type 1 diabetes, researchers from the University of Malta explained at the Society for Endocrinology annual conference in Harrogate, UK. Their study was also published in Acta Diabetologica. The researchers explained that type 1 diabetes rates have been steadily increasing by 3% annually for over a decade. This increase in reported cases has occurred mainly in rich nations. However, so far nobody has understood why...
Social Isolation Tied To Shorter Lifespan
Date: Mar-26-2013Social isolation, where a person has little actual interaction with others, more so than loneliness, a subjective feeling that one's social connections fall short of what we desire or need, is tied to premature death in older people. This was the finding of a new study led by epidemiologist Andrew Steptoe of University College London and colleagues that was published in the Proceedings of the National Academy of Sciences this week...
Cold Sores Could Lead To Increased Cognitive Problems
Date: Mar-26-2013Elderly adults who have specific infections - like the herpes cold sore virus - may have declined memory abilities and decreased thinking - more so than others in their age group, according to a new study published in Neurology. The researchers discovered that more than 1,600 older adults - those with herpes simplex and other viruses and bacteria achieved lower marks on standard mental skills tests. However, the outcomes do not necessarily mean that the infections are responsible...
Parkinson Disease Patients With Mild Cognitive Impairment At Increased Risk Of Dementia
Date: Mar-26-2013According to research published in JAMA Neurology, people with Parkinson disease (PD), who show symptoms of mild cognitive impairment, are at an increased risk of early dementia. As part of the Norwegian ParkWest study - which is analyzing the incidence and prognosis of PD in Norway - researchers analyzed the extent of mild cognitive impairment in PD patients and its progression to full blown dementia. Dementia is a progressive deterioration in cognitive function - intelligence. As the condition is progressive, symptoms gradually get worse...
Novel T-Cell Therapy Eradicates An Aggressive Leukemia In 2 Children
Date: Mar-26-2013Two children with an aggressive form of childhood leukemia had a complete remission of their disease - showing no evidence of cancer cells in their bodies - after treatment with a novel cell therapy that reprogrammed their immune cells to rapidly multiply and destroy leukemia cells. A research team from The Children's Hospital of Philadelphia and the University of Pennsylvania published the case report of two pediatric patients Online First in The New England Journal of Medicine. It will appear in the April 18 print issue...
Breath Test Identifies Heart Failure In Patients
Date: Mar-26-2013By analyzing patients' "breathprint", i.e. a single puff of exhaled air, researchers at the Cleveland Clinic have managed to quickly determine whether they have heart failure. They published their findings in the Journal of the American College of Cardiology. The authors pointed out that their prospective study was based on a small group of participants (61 patients). More extensive research is needed to confirm their initial promising results...
