A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single molecules - a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales. Dr. Eric Blough, a member of the research team and an associate professor in Marshall University's Department of Biological Sciences, said his group has shown how bionanomotors can be used some day to move and manipulate molecules at the nanoscale. Their research will be published in the Feb. 5 issue of the research journal Small. "Being able to manipulate a single molecule under controlled conditions is actually a pretty big challenge, " said Blough.
Stem cell research at the University of California, Riverside is about to gather speed thanks to the establishment of a new Stem Cell Core Facility (SCCF) - a shared facility providing infrastructure, equipment, and trained personnel for doing stem cell research that ordinarily would not be available in most laboratories. The SCCF, located in Noel Keen Hall, had its grand opening on Friday, Jan. 29. More than 200 visitors from all over Southern California attended the celebration that included tours of the Core labs, demonstrations of the facility's new equipment, posters on stem cell research being done at UCR, information on how to get started in stem cell research, and contests with prizes for the best posters and images.
Researchers in the UK and Belgium who scanned the brains of patients in a vegetative or minimally conscious state while they were asked to perform mental tasks found that some of them were able to control brain activity in a way that suggested signs of awareness and cognition, and in one case, the patient was even able to communicate "yes" and "no" via the brain scan. The researchers said that while it is still early days, they hope their method will lead to ways of enabling aware patients trapped in unresponsive bodies to control their environment, express their feelings, and communicate more fully. You can read about the study in a paper published online on 3 February in the New England Journal of Medicine, NEJM.
Intensive care unit patients are not the only ones likely to be severely depressed in the aftermath of hospitalization. Family and friends who care for them often suffer emotional and social hardship, too, according to a prospective study from the University of Pittsburgh School of Medicine that is the first to monitor patients and caregivers during a one-year period for predictors of depression and lifestyle disruption. The findings, published this month in Chest, indicate that the informal caregivers of ICU survivors endure even more stress than those caring for Alzheimer's disease patients, noted senior author Michael R. Pinsky, M.D.
Newborn screening for a metabolic disorder could lead to false positives -- adding stress to parents, costing money and possibly subjecting a baby to unnecessary follow-up treatment and dietary restrictions. But the benefits of diagnosing these children early and preventing the risk of mental retardation, disability or death outweigh the costs of a false positive, according to new U-M research published in the February issue of the journal Pediatrics. "Published studies of expanded newborn screening in a U.S. setting have resulted in favorable cost-effective ratios for screening for this illness but did not include primary data for quality of life effects for a false positive screen, " says Lisa Prosser, Ph.
In response to the safety alert issued by FDA on December 3, 2009 regarding the STERIS System 1® , Advanced Sterilization Products (ASP) has developed comprehensive solutions, new resources, financial assistance and educational initiatives to help those complying with the FDA safety alert better navigate through the transition, including an informational Webinar series that launches Friday, February 12. The Webinar series will provide important information for healthcare professionals concerned about the steps to ensure a smooth transition. The first ASPÔ sponsored Webinar, "Transitioning from the STERIS System 1, " aims to help facilities maintain standards of patient care and infection prevention by answering pressing questions such as: - What are ASP's alternatives to the SS1?
