Predictive value of serum myeloperoxidase (MPO) concentration combined with triglyceride-glucose index (TyG) for major adverse cardiaovascular events (MACE) in patients with coronary heart disease.

Background: Coronary heart disease (CHD) remains a leading cause of mortality globally. The prognostic value of myeloperoxidase (MPO) and the triglyceride-glucose (TyG) index in predicting adverse cardiovascular events among individuals with CHD remains uncertain. This study aimed to investigate the predictive value of MPO in combination with the TyG index for major adverse cardiovascular events (MACE) in patients with CHD.

Organocatalyzed Enantioselective C-N Bond-Forming SAr Reactions for Synthesizing Stereogenic-at-Boron BODIPYs.

The precise construction of boron stereogenic centers represents a significant, yet challenging frontier in asymmetric catalysis, garnering growing attention in recent years. However, feasible catalysis has primarily been limited to transition-metal-catalyzed desymmetrization of pro-chiral BODIPY molecules, while enantioselective synthesis via organocatalysis remains unexplored. Herein, we achieve an organocatalyzed C-N bond-forming SNAr reaction of 3,5-dihalogen BODIPYs via phase-transfer catalysis, enabling the efficient synthesis of a broad range of boron-stereogenic BODIPYs with excellent enantioselectivities (>40 examples, up to 99% ee).

Asymmetric S-Arylation of Sulfenamides to Access Axially Chiral Sulfilimines Enabled by Anionic Stereogenic-at-Cobalt(III) Complexes.

An efficient enantioselective coupling reaction between sulfenamides and cyclic diaryliodonium salts is established via adaptive Cu/anionic stereogenic-at-Co(III) complex combined catalysis, precisely synthesizing a broad range of axially chiral sulfilimines with excellent enantioselectivities, diastereoselectivities, regioselectivities, and chemoselectivities (67 examples under same conditions, up to 98 % ee). The following thermodynamically controlled pyramidal inversion enables efficient stereodivegent synthesis of all four stereoisomers. Mechanistic studies suggest that anionic stereogenic-at-cobalt(III) complexes serve as counteranions of diaryliodonium and anionic ligand of Cu(I) catalyst simultaneously, which could be regarded as an explanation for outstanding selectivities.

Characterization of on-road CO, HC and NO emissions for petrol vehicle fleet in China city.

Vehicle emissions are a major source of air pollution in urban areas. The impact on urban air quality could be reduced if the trends of vehicle emissions are well understood. In the present study, the real-world emissions of vehicles were measured using a remote sensing system at five sites in Hangzhou, China from February 2004 to August 2005.
