A study found significant differences in genetic effects between Chinese and non-Chinese studies on gene-disease associations. The researchers identified 161 Chinese studies on 12 topics, but only 20 were indexed in PubMed. This bias may lead to skewed evidence depending on language and publication sources.
Researchers found a link between placental microtransfusions and HIV transmission in mothers, particularly during vaginal delivery. The study suggests that better understanding of microtransfusions could lead to more effective treatments for preventing mother-to-child transmission of HIV.
Researchers found that only a third of high-risk patients were prescribed aspirin in 2003, despite its cost-effectiveness and recommended use for people with diabetes. The study suggests that physicians prioritize statins over aspirin due to advertising and preference.
Researchers found that macrophages from TB patients have high levels of DC-SIGN, a protein that helps Mycobacterium tuberculosis infect lung cells. Infection with TB causes nearby uninfected cells to also express DC-SIGN, making them more susceptible to infection.
Researchers have engineered mice to produce amyloid plaques in their brains, finding that treatment with drugs lowering Abeta production can prevent progression of Alzheimer's disease. However, treatment cannot reverse the disease. Early treatment with these drugs may be crucial in slowing or stopping its spread.
Researchers reported that most volunteers developed strong, specific, and long-lasting immune responses to the MSP3 protein after vaccination. The vaccine also demonstrated functional antibody responses that could inhibit malaria parasite growth in laboratory assays.
