Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

Chemistry – A European Journal, EarlyView.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

Preserved Spermatogenesis and Hormonal Function in Men Receiving a Pretomanid Regimen (BPaMZ) for Pulmonary Drug‐Resistant Tuberculosis

Clinical Pharmacology &Therapeutics, EarlyView.
Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...

Adhesion and formation of tags from MTA Fillapex compared with AH Plus® cement

, 2015
The aim of this study was two-fold:1) to evaluate, in vitro, the shear bond strength of two sealers by push-out test and 2) to assess the failures after displacement. Additionally, the formation of tags was observed by SEM.

A Study of High‐Emission Industries: How Policy, Strategy, and Technology Shape Corporate Social Responsibility Toward Carbon Neutrality

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The extant carbon neutrality (CN) literature largely offers macro‐ or meso‐level analyses, providing limited insights into implementation experiences that could inform granular policymaking and industry strategies. To address this gap, we examine the lived CN experiences of firms in the transportation, energy, manufacturing, and construction ...
