The study, led by Dr. Jenny Chang at Baylor College of Medicine, found that 88% of genes were correctly classified, allowing for personalized treatment strategies.
A study using camera pills found that people taking NSAIDs regularly are at increased risk of small intestinal mucosal ulceration and bleeding. The study, which used capsule endoscopy to visualize the entire small intestine, detected erosions in 62% of NSAID users compared to 5% of non-users.
Researchers at Baylor College of Medicine have made a breakthrough in developing a gene therapy that can cure diabetes in mice. The treatment uses the NeuroD gene to induce liver cells to produce insulin and other hormones associated with the pancreas' endocrine system.
Researchers found that women with high levels of AIB1 and HER-2 proteins in their tumors are more likely to experience poor outcomes with tamoxifen therapy. When either protein level is low, the risk of adverse effects decreases significantly.
Researchers at Baylor College of Medicine found that a specific enzyme is associated with high levels of HDL, which may have both positive and negative effects on cardiovascular health. The study suggests that the enzyme's impact on cholesterol transport to the liver could be beneficial or detrimental.
A new study finds that linezolid is as effective as vancomycin in treating infants and children with gram-positive infections, providing a valuable treatment option for this age group. The antibiotic is particularly promising for community-acquired MRSA infections, which are becoming increasingly difficult to manage.
