A study of 883 treatment-naïve HIV patients found that atazanavir/ritonavir once daily was as effective as lopinavir/ritonavir twice daily in reducing viral load and increasing CD4 cells. The once-daily regimen had less gastrointestinal toxicity but a higher rate of hyperbilirubinemia, supporting its use as a first-line treatment option.
A new study suggests that childhood obesity begins as early as age two, with over half of children reaching the overweight category by this age. Researchers found that obese children started gaining weight in infancy at a rapid rate, highlighting the need for early interventions to prevent future obesity.
A new MRI contrast medium, Gadofluorine M, has been developed to visualize inflammatory tissue damage in multiple sclerosis (MS). The study found that this medium enabled the detection of more inflammatory lesions in MS patients compared to conventional MRI images and contrast media.
A study of 490 black men found they ate an average of three servings of fruits and vegetables daily, despite the recommended nine servings per day. The researchers also identified barriers to food safety practices in restaurant employees, including inadequate training and resources.
A new antimicrobial surface coating, developed by a team of scientists, has shown promising results in reducing implant-related infections. The hybrid molecule combines two natural products with different modes of action, effectively hindering bacterial growth and attachment.
A new study published in the American Sociological Review found that individuals with personal connections to victims of the Iraq War or 9/11 terrorist attacks are less likely to approve of President Bush's performance, affecting both Republicans and Democrats. The pattern holds true across all demographics.
A new study found that targeting liver CB1 receptor may treat obesity-related conditions without brain-side effects, reversing severe insulin resistance and fatty liver in mice fed high-fat diets. The research indicates liver-specific CB1 is necessary for high-fat diet-induced fatty liver and related hormonal changes.
Researchers at the University of Michigan Hospitals found that 545 patients (0.6%) experienced allergic-like reactions after receiving nonionic iodinated contrast media, but 99% resolved completely within 24 hours with commonly used medications like diphenhydramine and corticosteroids.
A two-year study by UT Houston researchers found that 53% of women who tested positive for GBS during their first pregnancy were also positive during their second. The study suggests that retesting women in subsequent pregnancies may not be cost-effective due to the high recurrence rate.
Researchers discovered an extreme cooling event 12,700 years ago in Western Europe, with sediments revealing a short-term shift in atmospheric circulation. The findings suggest the climate system is not fully understood, with many puzzles remaining to be solved.
Researchers found that RTK inhibitors can be less effective in treating glioblastoma multiforme (GBM) due to cell death inhibition. Combining RTK and IAP inhibitors showed promise in inducing apoptosis in GBM cells, with enhanced efficacy in orthotopic mouse models.
A randomized, placebo-controlled study found that creatine supplementation had negligible effects on exercise function in patients with chronic obstructive pulmonary disease (COPD). Despite increased muscle creatine levels, the study's results suggest that physical training alone remains essential for improving outcomes.
