Lasers deemed highly effective treatment for excessive scars Posted: 27 Nov 2013 12:03 PM PST Current laser therapy approaches are effective for treating excessive scars resulting from abnormal wound healing, concludes a special topic paper in the December issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS). read more

Eliminate malaria by targeting enzyme in mosquito-borne parasite Posted: 27 Nov 2013 11:45 AM PST Using advanced methodologies that pit drug compounds against specific types of malaria parasite cells, an international team of scientists, including researchers at the University of California, San Diego School of Medicine and the Genomics Institute of the Novartis Research Foundation, have identified a potential new weapon and approach for attacking the parasites that cause malaria. Anopheles gambiae mosquitoes, a key vector of malaria and carrier of the Plasmodium falciparum parasite. read more

Researchers identify a rescuer for vital tumor-suppressor Posted: 27 Nov 2013 11:33 AM PST A protector for PTEN, a tumor-thwarting protein often missing in cancer cells, has emerged from research led by scientists at The University of Texas MD Anderson Cancer Center published online at Nature Cell Biology this week.     “We discovered that the enzyme USP13 stabilizes the PTEN protein by reversing a process that marks  various proteins for destruction by the cell’s proteasome,” said the paper’s senior author Li Ma, Ph.D., assistant professor of Experimental Radiation Oncology. read more

Gene mutation can cause excessive alcohol drinking Posted: 27 Nov 2013 09:49 AM PST  UK researchers have discovered a gene that regulates alcohol consumption and, when faulty, can cause excessive drinking in mice. The study found that normal mice drink little or no alcohol when offered a free choice between a bottle of water and a bottle of diluted alcohol. However, mice with a mutation in the gene Gabrb1 overwhelmingly preferred drinking alcohol over water, choosing to consume almost 85 per cent of their daily fluid as drinks containing alcohol. read more

Drug Regimen May Eliminate Colonization With Superbug CRE Posted: 27 Nov 2013 09:33 AM PST Orally administered, nonabsorbable antibiotics were effective in eradicating carbapenem-resistant Enterobacteriaceae (CRE) colonization, according to a new study published in the December issue of the American Journal of Infection Control, a publication of the Association for Professionals in Infection Control and Epidemiology (APIC).   read more

New aggressive HIV strain leads to faster AIDS development Posted: 27 Nov 2013 08:46 AM PST A recently discovered HIV strain leads to significantly faster development of AIDS than currently prevalent forms, according to new research from Lund University in Sweden. The period from infection to development of AIDS was the shortest reported among HIV-1 types, at around five years. There are over 60 different epidemic strains of HIV-1 in the world, and geographic regions are often dominated by one or two of these. If a person becomes infected with two different strains, they can fuse and a recombined form can occur. read more
