Covalent organic frameworks for radioactive iodine capture: structure and functionality.

The adsorption of radioactive iodine is a critical concern in nuclear safety and environmental protection due to its hazardous nature and long half-life. Covalent organic frameworks (COFs) have emerged as promising materials for capturing radioactive iodine owing to their tunable porosity, high surface area, and versatile functionalization capabilities. This review provides a comprehensive overview of the application of COFs in the adsorption of radioactive iodine.

Self-Assembly of Cluster-Mediated 3D Catenanes with Size-Specific Recognition Behavior.

Although interlocked three-dimensional molecules display unique properties associated with their spatial structures, their synthesis and study of their host-guest properties remain challenging. We report the formation of a novel [2]catenane, [EtN]@[(Tp*WSCuCl)(-bpype)](OTf) ([EtN][](OTf)), by self-assembly of the cluster node [Tp*WSCuCl] and the organic linker ()-1,2-diphenyl-1,2-bis(4-(pyridin-4-yl)phenyl)ethene (-bpype). Single-crystal X-ray and NMR analyses established that [] is formed by the interpenetration of two cluster-organic cages.

Development of a diagnostic assay by three-tube multiplex real-time PCR for simultaneous detection of nine microorganisms causing acute respiratory infections.

Acute respiratory infections are widespread in vulnerable populations of all ages and are characterized by a variety of symptoms. The underlying infection can be caused by a multitude of microorganisms, including viruses and bacteria. Early detection of respiratory infections through rapid pathogen screening is vital in averting infectious respiratory disease epidemics.

mA demethylase FTO regulates the apoptosis and inflammation of cardiomyocytes via YAP1 in ischemia-reperfusion injury.

Reperfusion therapy after acute myocardial infarction can induce myocardial ischemia-reperfusion injury (IRI). Novel evidence has illustrated that N-methyladenosine (mA) modification modulates the myocardial IRI progression. Here, our study focuses on the role of mA methyltransferase fat mass and obesity-associated protein (FTO) in myocardial ischemia/reoxygenation injury and explores potential regulatory mechanisms.

Serum Uric Acid and Cardiovascular or All-Cause Mortality in Peritoneal Dialysis Patients: A Systematic Review and Meta-Analysis.

Studies have shown inconsistent associations between serum uric acid (SUA) levels and mortality in peritoneal dialysis (PD) patients. We conducted this meta-analysis to determine whether SUA levels were associated with cardiovascular or all-cause mortality in PD patients. PubMed, Embase, Web of Science, the Cochrane Library, CNKI, VIP, Wanfang Database, and trial registry databases were systematically searched up to April 11, 2021.

A new record of the capped langur () in China.

The distribution of the capped langur () in China has become controversial since Shortridge's langur () was upgraded to a full species. The capped langur is considered to be distributed in northeast India, Bangladesh, Bhutan, and northwest Myanmar only (Brandon-Jones et al., 2004; Choudhury, 2008, 2014; Das et al.

Long Noncoding RNA H19 Acts as a Competing Endogenous RNA to Mediate CTGF Expression by Sponging miR-455 in Cardiac Fibrosis.

Cardiac fibrosis is closely related to multiple cardiovascular system diseases, and noncoding RNAs (ncRNAs), including long noncoding RNA (lncRNA) and microRNA (miRNA), have been reported to play a vital role in fibrogenesis. The present study aims to investigate the potential regulatory mechanism of lncRNA H19 and miR-455 on fibrosis-associated protein synthesis in cardiac fibroblasts (CFs). miRNA microarray assay revealed 34 significantly dysregulated miRNAs, including 13 upregulated miRNAs and 21 downregulated miRNAs.

[Classification of plastics with laser-induced breakdown spectroscopy based on principal component analysis and artificial neural network model].

The classification of seven kinds of plastic (ABS, PET, PP, PS, PVC, HDPE and PMMA) with the laser-induced breakdown spectroscopy based on artificial neural network model was investigated in the present paper. One hundred seventy LIBS spectra for each type of plastic were collected. Firstly, all 1 190 plastics LIBS spectra were studied with principal component analysis.
