Accumulation of Four Electrons on a Terphenyl (Bis)disulfide.

The activation of N , CO or H O to energy-rich products relies on multi-electron transfer reactions, and consequently it seems desirable to understand the basics of light-driven accumulation of multiple redox equivalents. Most of the previously reported molecular acceptors merely allow the storage of up to two electrons. We report on a terphenyl compound including two disulfide bridges, which undergoes four-electron reduction in two separate electrochemical steps, aided by a combination of potential compression and inversion.

Enucleation vs. vaporization of benign prostatic hyperplasia: a head-to-head comparison of the various outcomes and complications. A systematic review and meta-analysis.

Introduction: Vaporization of the prostate (VP) and endoscopic enucleation of the prostate (EEP) are reliable and frequently used methods for BPO relief. Both surgeries utilize lasers and EAU recommends them in similar patient cohorts. Our objective was to compare intra- and perioperative results of patients who had undergone VP and EEP.

A systematic review of nerve-sparing surgery for high-risk prostate cancer.

Introduction: We provide a systematic analysis of nerve-sparing surgery (NSS) to assess and summarize the risks and benefits of NSS in high-risk prostate cancer (PCa).

Evidence Acquisition: We have undertaken a systematic search of original articles using 3 databases: Medline/PubMed, Scopus, and Web of Science. Original articles in English containing outcomes of nerve-sparing radical prostatectomy (RP) for high-risk PCa were included.

Endoscopic lithotripsy with a SuperPulsed thulium-fiber laser for ureteral stones: A single-center experience.

Objectives: To estimate the efficacy and safety of SuperPulsed thulium-fiber laser ureteral lithotripsy and to identify optimal laser settings.

Methods: Patients with solitary stones were prospectively included. Lithotripsy was performed with a SuperPulsed thulium-fiber laser (NTO IRE-Polus, Fryazino, Russia) using a rigid ureteroscope 7.

Chemoselective Electrochemical Hydrogenation of Ketones and Aldehydes with a Well-Defined Base-Metal Catalyst.

Hydrogenation reactions are fundamental functional group transformations in chemical synthesis. Here, we introduce an electrochemical method for the hydrogenation of ketones and aldehydes by in situ formation of a Mn-H species. We utilise protons and electric current as surrogate for H and a base-metal complex to form selectively the alcohols.

The Impact of a Proton Relay in Binuclear α-Diimine-Mn(CO) Complexes on the CO Reduction Catalysis.

Herein, we describe the redox chemistry of bi- and mononuclear α-diimine-Mn(CO) complexes with an internal proton source in close proximity to the metal centers and their catalytic activity in the electrochemically driven CO reduction reactions. In order to address the impact of the two metal sites and of the proton source, we investigate a binuclear complex with phenol moiety, , a binuclear Mn complex with methoxyphenol unit instead, , and the mononuclear analogue with a phenol unit, . Spectroelectrochemical investigation of the complexes in dmf under a nitrogen atmosphere indicates that and undergo a reductive H formation forming [Mn(HL)(CO)Br] and [Mn(HL)(CO)], respectively, which is redox neutral for the complex and equivalent to a deprotonation of the phenol unit.
