Unraveling the Role of Functional Groups of Terephthalate in Enhancing the Electrochemical Oxygen Evolution Reaction of Nickel-Organic Framework Nanoarrays.

The platelike nickel-terephthalate-type metal-organic framework nanoarrays (Ni-BDC NAs) on carbon cloth are obtained by employing agaric-like Ni(OH) NAs as sacrificial templates. The microenvironment of Ni-BDC NAs is modulated by various neighboring functional groups (-NH, -NO, and -Br) on the carboxylate ligand, exerting minimal destructive effects on the structure and morphology of Ni-BDC NAs. The electrochemical oxygen evolution reaction (OER) of Ni-BDC-NH NAs, Ni-BDC-NO NAs, and Ni-BDC-Br NAs exhibited a significant enhancement compared to that of Ni-BDC NAs alone, as evidenced by both experimental and theoretical assessments.

Long-term smoking contributes to aging frailty and inflammatory response.

In recent years, the health challenges linked to frailty in the elderly, particularly those worsened by cigarette smoke, have become more pronounced. However, quantitative studies examining the impact of smoking dosage on frailty in this population remain limited. To address this gap, we developed a model using smoke-exposed elderly mice.

Identification of genetic variants of the gene in association with COPD susceptibility.

Background: Although existing studies have identified some genetic loci associated with chronic obstructive pulmonary disease (COPD) susceptibility, many variants remain to be discovered. The aim of this study was to further explore the potential relationship between single nucleotide polymorphisms (SNPs) and COPD risk.

Methods: Nine hundred and ninety-six subjects were recruited (498 COPD cases and 498 healthy controls).

Transanal vs Laparoscopic Total Mesorectal Excision and 3-Year Disease-Free Survival in Rectal Cancer: The TaLaR Randomized Clinical Trial.

Importance: Previous studies have demonstrated the advantages of short-term histopathological outcomes and complications associated with transanal total mesorectal excision (TME) compared with laparoscopic TME. However, the long-term oncological outcomes of transanal TME remain ambiguous. This study aims to compare 3-year disease-free survival of transanal TME with laparoscopic TME.

A rhamnose-rich O-antigen of MP20 is required for symbiosis with .

a β-proteobacterium, forms a nitrogen-fixing symbiosis with many species of the large legume genus as well as with common bean ( L.). are considered to have evolved nodulation independently from the well-studied α-proteobacteria symbionts of legumes.
