Screening for nasal carriage of Staphylococcus (S.) aureus reduces the risk of S. aureus peritonitis in patients on peritoneal dialysis (PD).

Introduction: Screening for nasal carriage of Staphylococcus (S.) aureus is associated with a reduction of peritoneal dialysis (PD)-related infections, but conflicting results have questioned the benefit of this practice. This study evaluated the clinical effectiveness of the screening program for nasal carriage of S.

Mild-Temperature Catalyzed Hydrosilylation for Simplified Carbohydrate Functionalization of Porous Silicon Nanoparticles.

Porous silicon is one of the most explored nanostructured materials in various biomedical applications owing to its remarkable properties. However, its inherent chemical instability mandates a robust surface modification procedure, and proper surface bioengineering is essential to ensure its effectiveness in the biomedical field. In this study, we introduce a one-pot functionalization strategy that simultaneously stabilizes porous silicon nanoparticles and decorates their surface with carbohydrates through hydrosilylation chemistry, combining mild temperatures and a Lewis acid catalyst.

A CD Study of a Structure-Based Selection of -Heterocyclic Bis-Carbene Gold(I) Complexes as Potential Ligands of the G-Quadruplex-Forming Human Telomeric hTel23 Sequence.

Herein, we report the structure-based selection via molecular docking of four -heterocyclic bis-carbene gold(I) complexes, whose potential as ligands for the hTel23 G-quadruplex structure has been investigated using circular dichroism (CD) spectroscopy, CD melting, and polyacrylamide gel electrophoresis (PAGE). The complex containing a bis(1,2,3,4,6,7,8,9-octahydro-11-11-pyridazino[1,2-a]indazol-11-yl) scaffold induces a transition from the hybrid (3 + 1) topology to a prevalent parallel G-quadruplex conformation, whereas the complex featuring a bis(2-(2-acetamidoethyl)-3-imidazo[1,5-a]pyridin-3(2)-yl) moiety disrupted the original G-quadruplex structure. These results deserve particular attention in light of the recent findings on the pathological involvements of G-quadruplexes in neurodegenerative diseases.
