Revealing Crucial Influences of Boron Support on Regulating Geometric and Electronic Structures of 3D Catalyst for Hydrogen Evolution and Oxygen Reduction Reactions.

Building insights into the structure-performance relationship of catalysts has been emphasized recently. However, it remains a challenge due to catalysts' various and complex structures, especially the easily overlooked influence of the support material. Here, we reveal the crucial influences of boron introduction on synthesizing 3D carbon nanotube monoliths with embedded multistate Co metals, i.

Exploring the Key Indicators for Off-Flavor in Industrial Osmanthus Absolute through Sensomics and Chemometric Approaches.

The occurrence of off-flavor in osmanthus absolutes has emerged as a significant concern that could hinder its broad market acceptance and associated economic development. In this study, key off-flavor molecules in industrial osmanthus absolute were identified through sensomics and chemometric approaches. A group of 10 off-flavor (OF) samples, eliciting smoky/phenolic, sweaty/sour, and spicy odors, were compared with 10 pleasant aroma (PA) samples through various analyses, including overall aroma assessment, comprehensive chemical profiling, aroma extract dilution analysis (AEDA), and orthogonal partial least-squares-discriminant analysis (OPLS-DA).

Revision of the orb-weaving spider genus Archer, 1960 (Araneae, Araneidae) from China.

The orb-weaver spider genus Archer, 1960 from China is revised, and three species, including two new species, are recognized: Mi & Wang, (♂♀) from Xizang and Mi & Wang, (♂♀) from Hainan; the type species, (Strand, 1906) (♂♀), is redescribed based on specimens from Guizhou and Hubei. A distributional map of the studied specimens is also provided.

Chemical proteomic profiling of lysine crotonylation using minimalist bioorthogonal probes in mammalian cells.

Protein lysine crotonylation has been found to be closely related to the occurrence and development of various diseases. Currently, site identification of crotonylation is mainly dependent on antibody enrichment; however, due to the cost, heterogeneity, and specificity of antibodies, it is desired to develop an alternative chemical tool to detect crotonylation. Herein, we report an alkynyl-functionalized bioorthogonal chemical probe, Cr-alkyne, for the detection and identification of protein lysine crotonylation in mammalian cells.

Left Atrial Dimension and CHADS-VASc Score in Predicting Stroke in Patients with Rheumatic Atrial Fibrillation.

Background: Rheumatic atrial fibrillation (AF) patients are at an elevated risk of stroke events, yet the associated risk factors remain unclear.

Objectives: This study aimed to evaluate the effectiveness of the CHADS-VASc score in predicting stroke events in rheumatic AF patients and explore potential enhancements for increased predicting accuracy in the Asian population, comparing it to nonvalvular AF.

Methods: A retrospective cohort study spanning March 2010 to December 2020 included 29,341 AF patients followed up for up to 10 years, with 1,942 identified as having rheumatic AF.
