Abstract:
... Environmental factors affecting the photocatalytic oxidation of volatile organic compounds (VOCs) have previously been studied experimentally, but there are few theoretical studies, especially those on surface intermolecular forces. Because of this, it is unclear how multiple coexisting factors impact photocatalytic processes. Herein, comprehensive multi-factorial impact mechanisms of the photocat ...
... L-tryptophan (Trp) is an essential amino acid for humans and plays crucial roles in many metabolic functions. Trp levels can be used for diagnosing different kinds of metabolic disorders and the symptoms associated with those diseases. Herein, a novel, simple and sensitive sensor based on 3D peony-like bimetallic conductive MOFs (Co–Ni-MOFs) was fabricated for the electrochemical determination of ...
... Avian infectious bronchitis virus (IBV) causes highly contagious respiratory reproductive and renal system diseases in chickens, and emergence of serotypic variants resulting from mutations in the viral S gene hampers vaccine management for IBV infection. In this study, to facilitate the molecular analysis of IBV pathogenesis and the development of a new-generation IBV vaccine, we established a re ...
... Gas chromatography is commonly employed to detect gaseous pollutants. However, gaseous pollutants in paper mills are multicomponent and difficult to be detected and analyzed by gas chromatography. Therefore, we developed a novel autoanalyzer with an embedded supervisory system, with which multicomponent gaseous pollutants in paper mills can be detected in real time. The autoanalyzer was applied in ...

Abstract:
... To obtain more information of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) transmission via faeces in/between farms, 360 swine faecal samples were randomly collected from different farms in China from 2017 to 2019. Sixty‐two ORF5 genes were amplified by PCR from 120 positive samples identified by real‐time RT‐PCR and further characterized by sequencing. Phylogenetic analysis based o ...
... Congenital anomalies are the main causes of infant death and disability. Previous studies have suggested that maternal exposure to particulate matter is related to congenital malformation. However, the conclusions of this study remain controversial. Hence, meta-analyses were performed to assess the relationship between maternal exposure to particulate matter and the risk of congenital anomalies. T ...

Abstract:
... To adopt cleaner production technology of photo-catalysis in papermaking industry and improve environmental sustainability, it is essential to understand the impact of ambient humidity on photo-catalytic degradations of gaseous pollutants. This study used TiO₂ colloid as catalyst to study the effects of ambient humidity (30–60%) on the photo-catalytic degradations of formaldehyde (HCHO), benzene ( ...

Abstract:
... VOCs in paper mills have severely exceeded the emission standards and their photo-catalytic degradations should focus on the experimental and theoretical studies. This work used TiO₂ colloid as catalyst to study the photo-catalytic degradations of mixed HCHO and C₆H₆ at five mixing ratios. The adsorption behaviors of pure forms and mixtures on the TiO₂ (101) surface were simulated using density fu ...

Abstract:
... Porcine reproductive and respiratory syndrome (PRRS) is one of the most important viral swine diseases, resulting in immense economic losses in Chinese pig industry. Currently, four major lineages: lineage 1 (NADC30-like), 3 (QYYZ-like), 5.1 (VR2332-like) and 8.7 (JXA1-like) of type 2 PRRSV (North American type) have been circulating in China based on classification system, which have caused conce ...
... Bagasse activated carbon (AC) and the new type of activated carbon (KAC) prepared with reactivation method of ZnCl₂-KOH were modified with triethylenetetramine (TETA) and tetraethylenepentamine (TEPA). The as-modified adsorbents for CO₂ separation were investigated by thermal gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), elemental analysis, N₂ adsorption–desorption, a ...
... The micro/mesoporous composite ZSM-5/KIT-6 was synthesized via the assembly procedure of preformed ZSM-5 seeds into mesostructured KIT-6, and mechanical mixtures with different contents of zeolite were prepared via a mechanical grinding procedure. These composites were used as adsorbents for the capture of CO₂ in the simulated flue gas conditions of 60 °C and 15 vol% CO₂ with a thermal gravimetric ...
... A novel amine modified composite was fabricated for CO₂ capture. Tetraethylenepentamine (TEPA) or polyethyleneimine (PEI) was selected to modify the micro/mesoporous ZSM-5/KIT-6 composite (ZK). With the porous nature of the support, large amine loadings from 50 to 80% were expected via a typical impregnation step. The CO₂ adsorption performance was investigated by thermal gravimetric analysis (TGA ...
... Porcine circovirus type 2 (PCV2) has been causing huge economic losses in Chinese swine herds since it was first identified in China in 1999. Genotypes of PCV2 except for PCV2c coexist in swine herds in China, which may facilitate virus recombination. In the current study, six novel PCV2 strains were detected in China, and these strains shared high nucleotide similarity of the Rep gene with the PC ...
... The development of robust and nontoxic membrane-penetrating materials is highly demanded for nonviral gene delivery. Herein, a photosensitizer (PS)-embedded, star-shaped helical polypeptide was developed, which combines the advantages of multivalency-enhanced intracellular DNA uptake and light-strengthened endosomal escape to enable highly efficient gene delivery with low toxicity. 5,10,15,20-Tetr ...
... Scratched alkyd varnish coating (AVC), with isophorone diisocyanate (IPDI) microcapsules as functional additives, display self-healing properties. Here we investigated the mechanism of the self-healing process using a water trigger in seawater. Electrochemical impedance spectroscopy was used to monitor the self-healing efficiency. A detailed examination of the penetration of seawater into the crev ...
... BACKGROUND: Secreted frizzled-related protein 5 (SFRP5) is an anti-inflammatory adipokine modulating metabolism dysfunction. This study aims to observe the effect of recombinant SFRP5 protein on nonalcoholic steatohepatitis (NASH). METHODS: We set up a prokaryotic expression system and purified the recombinant SFRP5 protein. Recombinant SFRP5 protein was further identified by SDS-PAGE, western blo ...
... During recent research on the fabrication of DNA microarrays, polymers have been intensively investigated as substrates for immobilizing oligonucleotides, due to their low cost, disposability and excellent processing flexibility. Among these, cyclic olefin copolymers (COCs) are of special interest because of their many favorable properties, including high glass transition temperature, low auto-flu ...

... Observational studies on dietary or circulating magnesium and risk of cardiovascular disease (CVD) in Chronic Kidney Disease (CKD) stage 1–4 have reported no-to-modest inverse associations. 24 h Urinary magnesium concentration (24 h UMg), an indicator of intestinal magnesium absorption, may provide better insight into the connection of CKD progression. We examined 3179 participants aged 18–74 year ...
