Epstein-Barr virus and multiple sclerosis
Fri, 05 Mar 2010 03:50:37 GMT
Scientists from the Harvard School of Public Health, Walter Reed Army Institute of Research, and a team of collaborators have observed for the first time that the risk of multiple sclerosis (MS) increases by a number of folds following infection with the Epstein-Barr virus (EBV). This finding implicates EBV as a contributory cause to multiple sclerosis. The study appears in an advance online edition of the journal Annals of Neurology and will appear in a later print edition........

How malaria parasite spread?
Fri, 05 Mar 2010 03:50:37 GMT
Malaria remains one of the most deadly infectious diseases. Yet, how Plasmodium, the malaria parasite, regulates its infectious cycle has remained an enigma despite decades of rigorous research. But now a research team led by a cell biologist at the University of California, Riverside has identified a mechanism by which Plasmodium intensively replicates itself in human blood to spread the disease........

Influenza vaccines in elderly
Fri, 05 Mar 2010 03:50:37 GMT
Evidence for the safety and efficacy of influenza vaccines in the over 65s is poor, despite the fact that vaccination has been recommended for the prevention of influenza in older people for the past 40 years. These are the conclusions of a new Cochrane Systematic Review. Adults aged 65 and over are some of the most vulnerable during influenza season and a priority for vaccination programmes. However, very few systematic reviews of the effectiveness of vaccines in this group have ever been carried out........

Energy Released From a Virus During Infection
Fri, 05 Mar 2010 03:50:37 GMT
Within a virus's tiny exterior is a store of energy waiting to be unleashed. When the virus encounters a host cell, this pent-up energy is released, propelling the viral DNA into the cell and turning it into a virus factory. For the first time, Carnegie Mellon University physicist Alex Evilevitch has directly measured the energy linked to the expulsion of viral DNA, a pivotal discovery toward fully understanding the physical mechanisms that control viral infection and designing drugs to interfere with the process........

HIV researchers solve key puzzle
Fri, 05 Mar 2010 03:50:37 GMT
Scientists have made a breakthrough in HIV research that had eluded researchers for over 20 years, potentially leading to better therapys for HIV, as per a research findings published recently in the journal Nature The researchers, from Imperial College London and Harvard University, have grown a crystal that reveals the structure of an enzyme called integrase, which is found in retroviruses like HIV. When HIV infects someone, it uses integrase to paste a copy of its genetic information into their DNA........

Proper vaccine refrigeration vital
Fri, 05 Mar 2010 03:50:37 GMT
Every year, billions of dollars worth of vaccines are shipped to thousands of medical providers across the country, and every year doctors must dispose of tens of millions of dollars worth of those vaccines because they became too warm or too cold while in storage. Now, scientists at the National Institute of Standards and Technology (NIST), with funding from and in collaboration with the Centers for Disease Control and Prevention (CDC), have completed the first of a series of tests to determine best practices for properly storing and monitoring the temperature of refrigerated vaccines........

Ffighting the deadly staph infection
Fri, 05 Mar 2010 03:50:37 GMT
Scientists at the University of Illinois at Chicago and Israel's Weizman Institute of Science have observed that two antibiotics working together might be more effective in fighting pathogenic bacteria than either drug on its own. Individually, lankacidin and lankamycin, two antibiotics produced naturally by the microbe streptomyces, are marginally effective in warding off pathogens, says Alexander Mankin, professor and associate director of the UIC Center for Pharmaceutical Biotechnology and lead investigator of the portion of the study conducted at UIC........

CT to diagnose appendicitis
Fri, 05 Mar 2010 03:50:37 GMT
Preoperative computed tomography (CT) may help reduce unnecessary surgeries in women of reproductive age with suspected acute appendicitis, as per a newly released study appearing in the recent issue of the journal Radiology "We observed that rising utilization of preoperative CT over the past decade, along with advances in CT technology, coincided with a significant decrease in negative appendectomies among women 45 years and younger," said Courtney A. Coursey, M.D., a radiologist at Emory University in Atlanta, who co-authored this study while a radiology fellow at Duke University Medical Center in Durham, N.C........

Face Masks and Hand Hygiene
Fri, 05 Mar 2010 03:50:37 GMT
Ordinary face masks and hand hygiene can effectively reduce the transmission of influenza-like illness during flu season. The finding comes from a newly released study, now available online, reported in the Feb. 15 issue of The Journal of Infectious Diseases. In an influenza pandemic, vaccination may not be initially available, and antiviral prescribing appears to be limited, which is why researchers need to understand how effective other measures are in preventing influenza........

Herpes medication does not reduce risk of HIV transmission
Fri, 05 Mar 2010 03:50:37 GMT
A five-year international multi-center clinical trial has observed that acyclovir, a drug widely used as a safe and effective therapy taken twice daily to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2. The results of the study are reported in the New England Journal (NEJM) online today, and will appear in the Feb. 4, 2010 issue of the publication........
