By furthering scientists? understanding of the molecular mechanisms that separate the minority of successful HIV antibodies from the majority of ineffective antibodies, the work may have implications for future attempts to design an HIV vaccine.
Scientists have what could be some very bad news for disease-causing bacteria. All three major classes of antibiotics that kill infectious bacteria do so in part by ramping up the production of harmful free radicals, researchers report in the September 7, 2007, issue of Cell, a publication of Cell Press. Because those different types of antibiotics each initially hit different targets, it had been believed they worked by independent means.
Australian parents need to be educated about managing fever in young children because many give medication incorrectly and often unnecessarily, according to a Queensland University of Technology nursing researcher.
A biomedical engineer at Purdue University has developed a new method to perform cardiopulmonary resuscitation that promises to be more effective than standard CPR because it increases nourishing blood flow through the heart by 25 percent over the current method.
Injection drug users are still at a very high risk of acquiring hepatitis C (HCV) and hepatitis B (HBV); however, needle-sharing is less common, and users do not become infected as quickly as they did in the past, according to a new study in the September issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).
Hepatitis C Virus (HCV) infects up to 500,000 people in the UK alone, many of the infections going undiagnosed. It is the single biggest cause of people requiring a liver transplant in Britain. Now, in a collaborative effort with groups across Europe and the USA, scientists from The University of Nottingham have found monoclonal antibodies which may be a significant step towards a vaccine.
In studies aiming to understand better the emergence and persistence of cholera in Africa, IRD and CNRS researchers showed the strong correlation that exists between outbreaks and the different parameters linked to climate changes in West Africa.
If you sit on cold boulders or forget to wear your woollen underwear, you can develop a urinary tract infection. However, these diseases are more complicated than this, and in some cases they have a genetic background.
After a role in initiating an NF-?B-mediated innate immune response to microbial challenge, AP-1 and STAT act to form part of a repressosome to down-regulate the transcription of antimicrobial peptides and thus to resolve the immune response.
So-called “vaginal rejuvenation,” “designer vaginoplasty,” “revirgination,” and “G-spot amplification” procedures are not medically indicated, nor is there documentation of their safety and effectiveness, said The American College of Obstetricians and Gynecologists (ACOG) in a new Committee Opinion published in the September issue of Obstetrics & Gynecology. Moreover, it is deceptive to give the impression that any of these procedures are accepted and routine surgical practices, according to ACOG.
