| Best way to treat malaria: Avoid using same drug for everyone, scientists say Fri, 05 Sep 2008 00:00:00 EDT |
(Princeton University) A team of scientists employing a sophisticated computer model pioneered at Princeton University and Resources for the Future has found that many governments worldwide are recommending the wrong kind of malaria treatment. |
| Changes in urine could lead to BSE test for live animals Fri, 05 Sep 2008 00:00:00 EDT |
(BioMed Central) Researchers have demonstrated that protein levels in urine samples can indicate both the presence and progress of Bovine Spongiform Encephalopathy disease in cattle. Publishing their findings in BioMed Central's open access journal Proteome Science, the scientists hope that their discovery might lead to the development of a urine-based test that could prevent the precautionary slaughter of many animals as now occurs when the disease is detected. |

(Journal of Clinical Investigation) Individuals who have a sexually transmitted disease and women with yeast and bacterial vaginal infections have an increased risk of becoming infected with HIV if exposed to the virus through sexual contact. Research published in the Journal of Clinical Investigation has now provided a new explanation as to how and why STDs have this effect. |
| Syracuse University partners with Serum Institute of India to develop vaccines for children Thu, 04 Sep 2008 00:00:00 EDT |
(Syracuse University) A unique partnership between Syracuse University and the Serum Institute of India could lead to better access to life-saving vaccines for children living in some of the most impoverished areas of the world. The Institute recently awarded $250,000 to a team of SU researchers led by Robert Doyle, assistant professor of chemistry in the College of Arts and Sciences, to develop new oral vaccines against tetanus and rotavirus, a severe form of diarrhea that affects infants and young children worldwide. |

| Neutral HIV presentations more likely to be considered inviting, study finds Thu, 04 Sep 2008 00:00:00 EDT |
(University of Illinois at Urbana-Champaign) A recent study found a method to increase enrollment among high-risk individuals in HIV prevention programs. |
| UVA reports promising method for reducing MRSA infections in hospitals Thu, 04 Sep 2008 00:00:00 EDT |
(University of Virginia Health System) In a study published in the Sept. 3, 2008, issue of Surgical Infections, UVA researchers report that switching between two antibiotics, linezolid and vancomycin, every three months in the surgical ICU decreased the MRSA infection rate from 1.9 to 1.4 patients per 100 admissions. In-hospital mortality from surgical ICU-acquired MRSA infections fell from 3.8 patients per year to none. |
| Researchers decode viral process that prepares cells for HIV infection Thu, 04 Sep 2008 00:00:00 EDT |
(George Mason University) With the publication of a study led by Yuntao Wu, assistant professor in George Mason University's department of molecular and microbiology, the medical community is one step closer to understanding how the human immunodeficiency virus attacks cells in the immune system. AIDS, which is caused by HIV, affected more than 33 million people worldwide in 2007 according to World Health Organization statistics. |
| Study reveals link between Apobec3 gene and neutralizing antibody response to retrovirus Thu, 04 Sep 2008 00:00:00 EDT |
(NIH/National Institute of Allergy and Infectious Diseases) Scientists have uncovered new evidence that strengthens the link between a host-cell gene called Apobec3 and the production of neutralizing antibodies to retroviruses. Published in the Sept. 5 issue of Science, the finding adds a new dimension to the set of possible explanations for why most people who are infected with HIV do not make neutralizing antibodies that effectively fight the virus. |
| Infectious, test tube-produced prions can jump the 'species barrier' Thu, 04 Sep 2008 00:00:00 EDT |
(Cell Press) Researchers have shown that they can create entirely new strains of infectious proteins known as prions in the laboratory by simply mixing infectious prions from one species with the normal prion proteins of another species. |
| Women who binge drink at greater risk of unsafe sex and sexually transmitted disease Thu, 04 Sep 2008 00:00:00 EDT |
(Alcoholism: Clinical & Experimental Research) Binge drinking (5 or more alcoholic beverages at one time) is associated with risky sexual behaviors. A new study examined this association by gender at a clinic for sexually transmitted diseases. Binge drinking increased the risk of unsafe sexual behaviors and having an STD for women patients. |
| Scientists uncover Ebola cell-invasion strategy Wed, 03 Sep 2008 00:00:00 EDT |
(University of Texas Medical Branch at Galveston) University of Texas Medical Branch at Galveston researchers have discovered a key biochemical link in the process by which the Ebola Zaire virus infects cells -- a critical step to finding a way to treat the deadly disease produced by the virus. |
| 'Superbug' breast infections controllable in nursing mothers, UT Southwestern researchers find Wed, 03 Sep 2008 00:00:00 EDT |
(UT Southwestern Medical Center) Many nursing mothers who have been hospitalized for breast abscesses are afflicted with the "superbug" methicillin-resistant Staphylococcus aureus, or MRSA, but according to new research by UT Southwestern Medical Center physicians, conservative treatment can deal with the problem. |
| C. Erec Stebbins awarded prestigious EUREKA grant Wed, 03 Sep 2008 00:00:00 EDT |
(Rockefeller University) C. Erec Stebbins, associate professor at the Rockefeller University, has been awarded an inaugural EUREKA grant from the National Institutes of Health for a project aimed at exploiting a bacteria-based "nanosyringe" as a means of delivering proteins into specific cells for therapeutic purposes. |

(Wiley-Blackwell) Scientists in the USA have established a way to predict outbreaks of cholera, making it easier to control. This finding could provide a model to predict and potentially control outbreaks of other important infectious diseases. |
| Virus weaves itself into the DNA transferred from parents to babies Tue, 02 Sep 2008 00:00:00 EDT |
(University of Rochester Medical Center) New research from the University of Rochester Medical Center shows that some parents pass on the human herpes virus 6 (HHV-6) to their children because it is integrated into their chromosomes. This is the first time a virus has been shown to become part of the human DNA and then get passed to subsequent generations. |
| Embargoed clinical news from Annals of Internal Medicine Mon, 01 Sep 2008 00:00:00 EDT |

| Scientists examine bird flu infections to monitor for 'pandemic' mutations Fri, 29 Aug 2008 00:00:00 EDT |
(Wellcome Trust) Scientists funded by the Wellcome Trust are to examine what is preventing the H5N1 avian influenza virus from causing a human pandemic and what mutations are required to realise its deadly potential. The research could hold the key to early identification of a potential influenza pandemic, and to developing drugs and a vaccine. |
| Flu shot does not reduce risk of death Fri, 29 Aug 2008 00:00:00 EDT |
(American Thoracic Society) The widely-held perception that the influenza vaccination reduces overall mortality risk in the elderly does not withstand careful scrutiny, according to researchers in Alberta. The vaccine does confer protection against specific strains of influenza, but its overall benefit appears to have been exaggerated by a number of observational studies that found a very large reduction in all-cause mortality among elderly patients who had been vaccinated. |
| New role for natural killers! Wed, 27 Aug 2008 00:00:00 EDT |
(University of York) Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer. |
| Study reveals gap in HIV testing knowledge among college students Wed, 27 Aug 2008 00:00:00 EDT |

| NIAID describes challenges, prospects for an HIV vaccine Wed, 27 Aug 2008 00:00:00 EDT |
(NIH/National Institute of Allergy and Infectious Diseases) Events of the past year in HIV vaccine research have led some to question whether an effective HIV vaccine will ever be developed. In the Aug. 28 edition of the New England Journal of Medicine, officials from NIAID examine the extraordinarily challenging properties of the virus that have made a vaccine elusive and outline the scientific questions that, if answered, could lead to an effective HIV vaccine. |
