Surface functionalized and defect enriched carbon nanotubes (oCNTs) by green ozone/HO treatment can efficiently anchor gold nanoparticles. This Au/oCNT could be stabilized and well dispersed after thermal treatment and showed robust catalytic activity (20.6 mmol g h) for the oxidative self-coupling of benzylamine to imine in solvent free conditions.

Recent studies have demonstrated that chronic stress can enhance the development of multiple human diseases, including cancer. However, the role of chronic stress in esophageal carcinogenesis and its underlying molecular mechanisms remain unclear. This study uncovered that dysregulated cholesterol metabolism significantly promotes esophageal carcinogenesis under chronic stress conditions.

Male infertility is a multifactorial condition for which the underlying causes frequently remain undefined. Genetic factors have long been associated with male fertility. However, many of them are poorly or not at all characterized and their biological functions are unknown.

Muscular dystrophies (MD) are a group of hereditary diseases marked by progressive muscle loss, leading to weakness and degeneration of skeletal muscles. These conditions often result from structural defects in the Dystrophin-Glycoprotein Complex (DGC), as seen in Duchenne Muscular Dystrophy (DMD) and Becker Muscular Dystrophy (BMD). Since MDs currently have no cure, research has focused on identifying potential therapeutic targets to improve patients' quality of life.

Direct Ink Writing, an extrusion-based 3D printing technique, has attracted growing interest due to its ability to process a broad range of materials and integrate multifunctional printheads with features such as shape-changing nozzles, in-situ curing, material switching, and material mixing. Despite these advancements, incorporating auxiliary controls into Geometry Code (G-Code), the standard programming language for these printers, remains challenging. G-Code's line-by-line execution requires auxiliary control commands to interrupt the print path motion, causing defects in the printed structure.

The imbalance between Tregs and proinflammatory Th17 cells in children with biliary atresia (BA) causes immune damage to cholangiocytes. Dimethyl fumarate (DMF), an immunomodulatory drug, regulates the Treg/Th17 balance in diseases like multiple sclerosis (MS). This study explores DMF's effect on Treg/Th17 balance in BA and its potential mechanism.
