Cobalt-Cluster-Based Metal-Organic-Framework-Catalyzed Carboxylative Cyclization of Propargylic Amines with CO from Flue Gas.

The fixation of carbon dioxide (CO) directly from flue gas into valuable chemicals like 2-oxazolidinones is of great significance for economic and environmental benefits, which is typically catalyzed by noble-metal catalysts and under harsh conditions. Herein, a novel 2-fold interpenetrated framework {[Co(μ-O)(TCA)(HDPTA)]·2HO·2DMF} [Co(II)-based metal-organic framework ()] containing [Co] clusters and highly dense amino groups (-NH) dispersed in the channel was prepared, exhibiting high solvent/pH stability and CO adsorption capacity (24.9 cm·g).

Absolute risk prediction for esophageal squamous cell carcinoma adaptable to regional disease burden across diverse regions.

Background: Esophageal squamous cell carcinoma (ESCC) exhibits a long latency period and has a significant geographical disparity in incidence, which underscores the need for models predicting the long-term absolute risk adaptable to regional disease burden.

Methods: 31,883 participants in a large-scale population-based screening trial (Hua County, China) were enrolled to develop the model. Severe dysplasia and above (SDA) identified at screening or follow-up were defined as the outcome.

Methyl-dependent auto-regulation of the DNA N6-adenine methyltransferase AMT1 in the unicellular eukaryote Tetrahymena thermophila.

DNA N6-methyladenine (6mA) is a potential epigenetic mark involved in gene transcription in eukaryotes, yet the regulatory mechanism governing its methyltransferase (MTase) activity remains obscure. Here, we exploited the 6mA MTase AMT1 to elucidate its auto-regulation in the unicellular eukaryote Tetrahymena thermophila. The detailed endogenous localization of AMT1 in vegetative and sexual stages revealed a correlation between the 6mA reestablishment in the new MAC and the occurrence of zygotically expressed AMT1.

Correlation of P53 expression and epithelial-mesenchymal transition in non-small cell lung cancer.

Background: Investigation of a potential prognostic marker expressed in non-small cell lung cancer (NSCLC) can help patients benefit from new target therapeuticmodalities.

Aims: To study the expression and correlation of P53 protein and epithelial-mesenchymal transition (EMT) related makers in NSCLC.

Materials And Methods: 32 cases were selected for immunohistochemistry analysis to evaluate the expression of P53 and EMT-related makers.

Antibiotic resistance genes (ARGs) in microorganisms and their indications for the nitrogen/sulfur cycle in the East China Sea sediments.

Antibiotic resistance genes (ARGs) are emerging environmental pollutants, posing an escalating threat to public health and environmental security worldwide. However, the relationship between ARGs and microbial communities in the environment, as well as their ecological effects on the microbe-mediated materials cycle remain unclear. In this study, we investigated the spatial distribution pattern, influence mechanism, relationship with microorganisms, and their effects on the elemental cycling of ARGs in East China Sea sediments.
