Women who are obese, have type 2 diabetes or a family history of type 2 diabetes could one day have more successful pregnancies because of a study at Washington University School of Medicine in St. Louis.
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.
Boston University School of Medicine and Boston Medical Center have adopted a new policy regulating interaction among clinicians and representatives of the pharmaceutical and device industries. The new policies are among the most stringent of academic medical centers in the US.
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.
Efforts to halt underage drinking often focus on peer pressure and the prevention of risky behaviors, but the American Association for the Advancement of Science (AAAS) is undertaking a new federally funded project to give middle-school children a science-based understanding of what can happen to them if they use alcohol.
In a study published in the September 6, 2007, issue of the journal Nature, researchers showed that two key proteins join together at the precise location where energy of motion is turned into electrical impulses. These proteins, cadherin 23 and protocadherin 15, are part of a complex of proteins called ?tip links? that are on hair cells in the inner ear. The tip link is believed to have a central function in the conversion of physical cues into electrochemical signals.
Non-Caucasian patients seeking medical care for primary biliary cirrhosis have more severe liver disease compared to Caucasian patients, a new study has found. The reasons for this disparity are not clear, say the authors.
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).
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.
