The role of adenoidectomy and/or tonsillectomy in the treatment of nocturnal enuresis in OSA children: a single-arm meta-analysis.

Purpose: To evaluate the efficacy of tonsillectomy and/or adenoidectomy for the treatment of nocturnal enuresis (NE) in children with obstructive sleep apnea (OSA).

Methods: PubMed, Embase, the Cochrane Library, and Web of Science were searched from inception to December 2023. We included all studies of children with OSA and NE who underwent adenoidectomy and/or tonsillectomy.

Influence of Dissolved O2 in Organic Solvents on CuOEP Supramolecular Self-Assembly on Graphite.

The supramolecular self-assembly of copper(II) octaethylporphyrin (CuOEP) and octaethylporphyrin (H2OEP) on graphitic surfaces immersed in organic solvents (dichlorobenzene, dodecane) is studied using scanning tunneling microscopy (STM) and Raman spectroscopy. STM reveals that the self-assembled structure of CuOEP in 1,2-dichlorobenzene is significantly altered by dissolved oxygen within the solvent. Raman spectroscopy reveals that the presence of the oxygen alters the molecule-substrate interaction, which is attributed to the adsorption of oxygen on the Cu center of the CuOEP, which is facilitated by electron transfer from the graphitic surface.

Graphene Membranes for Atmospheric Pressure Photoelectron Spectroscopy.

Atmospheric pressure X-ray photoelectron spectroscopy (XPS) is demonstrated using single-layer graphene membranes as photoelectron-transparent barriers that sustain pressure differences in excess of 6 orders of magnitude. The graphene serves as a support for catalyst nanoparticles under atmospheric pressure reaction conditions (up to 1.5 bar), where XPS allows the oxidation state of Cu nanoparticles and gas phase species to be simultaneously probed.
