Avelumab Maintenance Therapy in Advanced Urothelial Carcinoma: Implications of Timing and Treatment Sequencing.

Background: Platinum-based chemotherapy (PBC) followed by avelumab maintenance is a treatment option for patients with advanced urothelial carcinoma (aUC) patients. However, the optimal treatment sequencing in the era of antibody-drug conjugates (ADCs) is yet to be determined. Recent studies suggest that the timing of immune checkpoint inhibitor (ICI) administration may impact patient outcomes, with a potential benefit from morning infusions.

Understanding Catalytic Enantioselective C-H Bond Oxidation at Nonactivated Methylenes Through Predictive Statistical Modeling Analysis.

Enantioselective C(sp)-H bond oxidation is a powerful strategy for installing functionality in C(sp)-H rich molecules. Site- and enantioselective oxidation of strong C-H bonds in monosubstituted cyclohexanes with hydrogen peroxide catalyzed by aminopyridine manganese catalysts in combination with alkanoic acids has been recently described. Mechanistic uncertainties and nonobvious enantioselectivity trends challenge development of the full potential of this reaction as a powerful synthetic tool.

Isoelectronic Push-Pull Fluorescent Difluoroborates: Halogen Bonding and Photophysical Properties.

The structural and photophysical properties in the halogen bonding environment were thoroughly studied for a newly synthesized series of fluorescent dyes and their model derivatives. The analysis revealed that the ground-state interactions among both series are likewise. The fluorescent dyes have push-pull topology, and there is a low-lying charge-transfer (CT) excited state in their electronic structure.

All-Cellulose Hydrogel-Based Bioinks for the Versatile 3D Bioprinting of Different Cell Lines.

The development of bioink formulations with suitable properties is fundamental for the progress of 3D bioprinting. The potential of cellulose, the most abundant biopolymer, in this realm has often been underestimated, relegating it essentially to a reinforcement additive of bioinks. In this work, cell-laden bioink formulations, composed exclusively of cellulose, viz.

Comparison of video laryngoscopy and direct laryngoscopy for urgent intubation in newborn infants: A meta-analysis.

Background: Securing a stable airway is a critical component in neonatal resuscitation. Compared to direct laryngoscopy, video laryngoscopy provides improved visualization of the glottis, potentially enhancing the success rate of intubation. This systematic review and meta-analysis were conducted to assess and compare the efficacy and safety of video laryngoscopy versus direct laryngoscopy in neonatal intubation.
