Pitt Team Reports In Nature That Unique Portion Of Enzyme Fights Lung Infection
An enzyme known to play a key role in the development of emphysema serves as the first line of defense against bacterial infection of the lung, according to researchers at the University of Pittsburgh School of Medicine. They also found that the antimicrobial activity comes from a small portion of the enzyme that is structurally and sequentially unique in nature.

$500,000 Gruber Neuroscience Prize Awarded To Hall, Rosbash And Young
The 2009 Neuroscience Prize of The Peter and Patricia Gruber Foundation is being awarded to Jeffrey Hall, professor of neurogenetics at the University of Maine; Michael Rosbash, professor and director of the National Center for Behavioral Genomics at Brandeis University; and Michael Young, professor and head of the Laboratory of Genetics at Rockefeller University. On October 18, at the annual meeting of the Society for Neuroscience in Chicago, Illinois, these three distinguished scientists will receive this prestigious international award for their groundbreaking discoveries of the molecular mechanisms that control circadian (daily) rhythms in the nervous system. Their research was the first to establish a simple relationship between single genes and a complex behavior.

Mimic-effect: Video Therapy Helps Stroke Patients

Video therapy, through which certain brain sectors are activated by visual stimuli, can help restore movement in patients suffering stroke-induced paralysis. That conclusion is part of a current study that researchers from Konstanz, Freiburg and Magdeburg, Germany, are presenting at the current meeting of the European Neurological Society (ENS) in Milan, Italy. This major meeting in European neurology gathers more than 2,900 experts from all over the world. The role played by brain mirror neurons is central in this context. "The application of the mirror neuron system has extended into the field of stroke rehabilitation through mirror- or video-therapy," explained Professor Christian Dettmers (Konstanz). "By observing motion sequences stroke patients should overcome their paralysis more rapidly than with physiotherapy alone. Current literature has demonstrated that action observation exclusively or predominantly stimulates the non-affected hemisphere." The current German study, in which eight right hemispheric and eight left hemispheric stroke patients with hand pareses participated, shows that the mimic-effect goes beyond this, as verified by functional magnetic resonance imaging. "Cortical activation encompassed a symmetrical bilateral pattern: the affected hemispheres were stimulated to the same degree as the non-affected hemisphere. Our data clearly support applicability of video-therapy in stroke patients," Professor Dettmers concludes. Abstract: ENS abstract O85: Nedelko et al, Action observation and imagery conducted with stroke patients stimulate both hemispheres: the affected and non-affected. European Neurological Society
