Understanding how HIV interacts with the body's own defences may lead to new treatment opportunities
Date: Nov-08-2013Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defence systems. Their study shows how 'uncloaking' the virus using an experimental drug triggers an immune response that stops the virus from replicating in cells grown in the laboratory. The findings could lead to new treatments and help to improve existing therapies for HIV infection...
Signs of autism identified in the first months of life
Date: Nov-08-2013Researchers at Marcus Autism Center, Children's Healthcare of Atlanta and Emory University School of Medicine have identified signs of autism present in the first months of life. The researchers followed babies from birth until 3 years of age, using eye-tracking technology, to measure the way infants look at and respond to social cues. Infants later diagnosed with autism showed declining attention to the eyes of other people, from the age of 2 months onwards. The results are reported in the advanced online publication of the journal Nature...
How does electrical stimulation modulate electrophysiological environment after spinal cord injury?
Date: Nov-08-2013An injury potential is the direct current potential difference between the site of spinal cord injury and healthy nerves. Its initial amplitude is a significant indicator of the severity of spinal cord injury. This injury potential, as well as injury current, can be modulated by direct current field stimulation; however, the appropriate parameters of the electrical field are hard to define. Dr...
Parkinson's disease and psychosis
Date: Nov-08-2013Psychosis is a common non-motor symptom of Parkinson's disease whose pathogenesis remains poorly understood. Parkinson's disease in conjunction with psychosis has been shown to induce injury to extracorticospinal tracts as well as within some cortical areas...

Call for sustained public endorsement and funding for human stem cell research
Date: Nov-08-2013The European Science Foundation reports on the scientific and policy issues surrounding human stem cell research across Europe A strategic report from the European Science Foundation examines the key scientific questions for human stem cell research in the context of the rapidly emerging field of regenerative medicine. In parallel to the potential new treatments for incurable diseases resulting from stem cell research, heated ethical and legal debates have arisen across the world...

High risk of clots for hospitalized pregnant women
Date: Nov-08-2013Pregnant women who are admitted to the hospital for reasons other than delivery are at an increased risk of serious blood clots, according to new research published by the BMJ. Venous thromboembolism (VTE) is one of the leading causes of maternal death in developed countries, affecting 1-2 pregnancies in every 1,000. The new study suggests that risks are higher for women aged 35 and over who are hospitalized for 3 days or more, especially if they are in late pregnancy...

Tool to help GIs manage HCV patients
Date: Nov-08-2013The American Gastroenterological Association (AGA) Clinical Decision Tool for the Screening and Evaluation of Hepatitis C (HCV) will help gastroenterologists in the early management of HCV-positive patients, according to a new paper in Gastroenterology, the official journal of the American Gastroenterological Association. Chronic HCV has a significant impact on the adult population and is a disease for which much progress has been made in its treatment. "The publication of this clinical decision support tool marks a milestone for the AGA," according to John I...
