Crystal facet and Na-doping dual engineering ultrathin BiOCl nanosheets with efficient oxygen activation for enhanced photocatalytic performance.

Photocatalytic oxidation (PCO) based on semiconductors offers a sustainable and promising way for environmental remediation. However, the photocatalytic performance currently suffers from weak light-harvesting ability, rapid charge combination and a lack of accessible reactive sites. Ultrathin two-dimensional (2D) materials are ideal candidates to overcome these problems and become hotpots in the research fields.

Identification and molecular analysis of 17 novel variants of hydroxymethylbilane synthase in Chinese patients with acute intermittent porphyria.

A partial deficiency of the heme biosynthetic enzyme hydroxymethylbilane synthase (HMBS) leads to acute intermittent porphyria (AIP), a severe neurovisceral, autosomal dominant disorder with low penetrance. Even though in-depth investigations of the HMBS variants have been carried out by researchers in Britain, France, Russia, and Sweden, this area remains uninvestigated in China owing to the rarity and lack of clinical understanding of the disease. In this study, 78 unrelated AIP patients revealed 48 different HMBS variants, of which 17 were novel.
