Association of the triglyceride-glucose index with cardiovascular mortality risk and competing risks in arthritis patients.

This study aims to investigate the relationship between the triglyceride-glucose index (TyG) and all-cause mortality as well as cardiovascular mortality in arthritis patients. Additionally, it seeks to analyze the nonlinear characteristics and threshold effects of TyG index. We included 5,559 adult participants with arthritis from the 1999-2018 National Health and Nutrition Examination Survey (NHANES).

Multiple cobalt active sites evenly embedded in mesoporous carbon nanospheres derived from a polymer-metal-organic framework: efficient removal and photodegradation of malachite green.

A series of robust photocatalysts of mesoporous carbon nanospheres embedded with multiple cobalt active sites (Co/Co O @mC) have been constructed for efficient removal and photodegradation of malachite green (MG). Here, a cobalt-based polymeric-metal-organic framework (polyMOF(Co)) was constructed by using a polyether ligand containing 1,4-benzenedicarboxylic acid units. Afterward, polyMOF(Co) was calcined into a series of Co/Co O @mC hybrids at diverse high temperatures (400, 600, and 800 °C) under a N atmosphere.

Multiple active cobalt species embedded in microporous nitrogen-doped carbon network for the selective production of hydrogen peroxide.

To obtain excellent electrocatalysts for improving HO yield and selectivity, we formulated a novel method for embedding cobalt catalytic active sites in porous two-dimensional nitrogen-doped carbon network (CN) network and employed them as excellent two-electron oxygen reduction reaction (2e-ORR) electrocatalysts. The polymeric cobalt-based metal-organic framework (polyCo-MOF) and melamine-cyanuric acid-complex (MCA) hybrid (denoted as polyCo-MOF@MCA) was used as a precursor for preparing a series of electrocatalysts comprising multiple active sites such as metallic Co, CoO, or Co-N, which are homogeneously embedded in the porous two-dimensional CN network through pyrolysis at high temperatures (600 °C, 700 °C, and 800 °C) under N atmosphere. The obtained CoO/Co@CN hybrid by pyrolyzing polyCo-MOF@MCA at 700 °C displayed remarkably high HO production and large selectivity in an alkaline solution.

Universal biosensing platform based on polyMn-MOF nanosheets for efficient analysis of foodborne pathogens from diverse foodstuffs.

A universal electrochemical aptasensing strategy was developed for sensitive detection of various pathogenic bacteria (such as Staphylococcus aureus, Escherichia coli O157:H7, and Salmonella enterica) that commonly existed in food products. Diverse categories of pathogenic bacterium-targeting aptamers were separately immobilized over the polyMOF, which was prepared using the polyether polymer ligand containing 1,4-benzenedicarboxylic acid (polyHbdc) units as building block, 4,4'-bipyridine as co-ligand, polyvinyl pyrrolidone as structural regulator, and MnCl as metal centers (represented by polyMn-MOF). The developed polyMn-MOF-based aptasensor illustrated ultralow limits of detection for three kinds of foodborne pathogens (2.

Electrochemical aptasensing strategy based on a multivariate polymertitanium-metal-organic framework for zearalenone analysis.

An electrochemical aptasensing strategy was developed with a novel bioplatform based on a multivariate titanium metal-organic framework, i.e. MTV polyMOF(Ti), to detect zearalenone (ZEN).
