European multicentre study on outcome of surgery for sporadic primary hyperparathyroidism

BJS (British Journal of Surgery), EarlyView., 2020
Some 5861 patients undergoing first‐time surgery for sporadic primary hyperparathyroidism were registered in the Eurocrine® database between 2015 and 2018. The use of intraoperative parathyroid hormone measurement decreased the risk of conversion and persistent hypercalcaemia.

Regioselective Synthesis of Benzylsilanols from Kobayashi‐Type Reagents via C(sp3)─H Bond Activating 1,4‐Palladium Migration

Angewandte Chemie, EarlyView.
A Pd‐catalyzed regioselective synthesis of benzylsilanols from Kobayashi‐type reagents has been developed through a mechanistically distinct approach involving 1,4‐Pd migration followed by intramolecular transmetalation. The reaction can be combined with various prior transition‐metal‐catalyzed processes and the resulting benzylsilanols have been ...

Highly Efficient Extraction of 212 Pb/212Bi from the Decay Chain of 232Th‐Based on Anion Exchange in Bromide Medium

Advanced Science, EarlyView.
This work provides an effective strategy for selectively extracting 212Pb and 212Bi from the decay chain of 232Th as well as its mechanism illustration. Using the novel strategy, 2.07 MBq of 212Pb is successfully separated from 232Th and its daughters, which enables the supply of 212Pb/212Bi directly from the abundant natural thorium resource to be ...

Convergent Valorization via Scalable C═N Bond Electrosynthesis Through Metal‐Dopant Interfacial Engineering in a Flow Electrolyzer

Angewandte Chemie, EarlyView.
This study establishes an innovative approach to synthesize organonitrogens featuring C═N bonds efficiently using non‐precious metal‐doped MoS2 in a flow electrolyzer. Fe dopant significantly enhances Faradaic efficiency and yield rate, achieving over 81% and 2630 mmol h−1 g−1 for formaldoxime production. This platform upcycles pollutants into valuable

Revisiting Target‐Aware de novo Molecular Generation with TarPass: Between Rational Design and Texas Sharpshooter

Advanced Science, EarlyView.
TarPass provides a rigorous benchmark for target‐aware de novo molecular generation by jointly evaluating protein‐ligand interactions, molecular plausibility, and drug‐likeness on 18 well‐studied targets. Results show that current models often fail to consistently surpass random baseline in target‐specific enrichment, while post hoc multi‐tier virtual ...
