A fundamental malaria discovery
Sat, 21 Jan 2012 00:37:29 GMT
A team of scientists led by Kasturi Haldar and Souvik Bhattacharjee of the University of Notre Dame's Center for Rare and Neglected Diseases has made a fundamental discovery in understanding how malaria parasites cause deadly disease. The scientists show how parasites target proteins to the surface of the red blood cell that enables sticking to and blocking blood vessels. Strategies that prevent this host-targeting process will block disease........

New way to ensure effectiveness of TB treatment
Sat, 21 Jan 2012 00:37:29 GMT
A UT Southwestern Medical Center study using a sophisticated "glass mouse" research model has observed that multidrug-resistant tuberculosis (TB) is more likely caused in patients by speedy drug metabolism rather than inconsistent doses, as is widely believed. If the study published in The Journal of Infectious Diseases is borne out in future investigations, it may lead to better ways to treat one of the world's major infectious diseases. Health workers worldwide currently are mandatory to witness each administration of the combination of drugs during months of treatment........

African-Americans with SLE more responsive to flu vaccine
Sat, 21 Jan 2012 00:37:29 GMT
New research shows that African Americans with systemic lupus erythematosus (SLE) had a higher antibody response to influenza vaccination than European American patients. Treatment with prednisone, a history of hemolytic anemia, and increased disease flares were also associated with low antibody response in SLE patients who received the flu vaccine as per the study now available in Arthritis and Rheumatism, a peer-evaluated journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR)........

Quadruple therapy shows 100 percent SVR for HCV patients
Sat, 21 Jan 2012 00:37:29 GMT
Exciting new data presented today at the International Liver CongressTM 2011 show that quadruple treatment in chronic hepatitis C (HCV) patients suppressed the emergence of resistant variants and resulted in a 100% rate of sustained virological response - undetectable HCV RNA - 12 weeks after therapy (SVR12).1........

Promising target for AIDS vaccine
Sat, 21 Jan 2012 00:37:29 GMT
A section of the AIDS virus's protein envelope once considered an improbable target for a vaccine now may be one of the most promising, new research by Dana-Farber Cancer Institute researchers indicates. The section, a twisting strand of protein known as the V3 loop, is an attractive vaccine target because immune system antibodies aimed at the loop may offer protection against multiple genetic subtypes of HIV-1, the virus that causes AIDS. This is a key prerequisite of any AIDS vaccine because the viruses mutate rapidly and by now comprise millions of different strains that are grouped into different genetic subtypes, or "clades." The researchers' findings are published online in the Public Library of Science journal PLoS One. ........

Hepatitis C drug may revolutionize treatment
Sat, 21 Jan 2012 00:37:29 GMT
The drug boceprevir helps cure hard-to-treat hepatitis C, says Saint Louis University investigator Bruce R. Bacon, M.D., author of the March 31 New England Journal (NEJM) article detailing the study's findings. The results, which were first reported at the 61st annual meeting of the American Association for the Study of Liver Disease's last November, offer a brighter outlook for patients who have not responded to standard therapy........

Better Images of Bacteria
Sat, 21 Jan 2012 00:37:29 GMT
It's a cloak that surpasses all others: a microscopic carbon cloak made of graphene that could change the way bacteria and other cells are imaged. Vikas Berry, assistant professor of chemical engineering at Kansas State University, and his research team are wrapping bacteria with graphene to address current challenges with imaging bacteria under electron microscopes. Berry's method creates a carbon cloak that protects the bacteria, allowing them to be imaged at their natural size and increasing the image's resolution........

Focus on Prion Diseases
Sat, 21 Jan 2012 00:37:29 GMT
New research by Chongsuk Ryou, researcher at the UK Sanders-Brown Center on Aging and professor of microbiology, immunology and molecular genetics in the UK College of Medicine, may shed light on possible therapys for prion diseases. Prion diseases, which include Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy ("mad cow" disease) in cattle, are caused by prions - unconventional pathogens composed of infectious protein particles and resistant to conventional sterilization procedures. Presently there is no known agent or procedure that can halt or reverse damage caused by prion disease........

Keeping an eye on H1N1
Sat, 21 Jan 2012 00:37:29 GMT
In the fall of 1917, a new strain of influenza swirled around the globe. At first, it resembled a typical flu epidemic: Most deaths occurred among the elderly, while younger people recovered quickly. However, in the summer of 1918, a deadlier version of the same virus began spreading, with disastrous consequence. In total, the pandemic killed at least 50 million people - about 3 percent of the world's population at the time........

HIV vaccine impacts the genetic makeup of the virus
Sat, 21 Jan 2012 00:37:29 GMT
An AIDS vaccine tested in people, but found to be ineffective, influenced the genetic makeup of the virus that slipped past. The findings suggest new ideas for developing HIV vaccines. The results were published Feb. 27 in Nature Medicine This is the first evidence that vaccine-induced cellular immune responses against HIV-1 infection exert selective pressure on the virus. "Selective pressure" refers to environmental demands that favor certain genetic traits over others........
