Visible-light-driven hydrogen evolution using a polyoxometalate-based copper molecular catalyst.

Polyoxometalate-based copper clusters as promising hydrogen evolution catalysts are rarely reported. Here, [Cu(OH)(HO)(A-α-SiWO)] (1) was tested as an effective molecular catalyst for visible-light-driven H evolution. A high turnover number (TON) of 718.

Effectiveness of vitamin D for adult patients with gingivitis.

Background: This study aims to explore the effectiveness of vitamin D for the management of adult patients with gingivitis.

Methods: We will perform a comprehensive search from the following electronic databases: Cochrane Library, PUBMED, EMBASE, AMED, CINAHL, WANGFANG, VIP, CBM, and China National Knowledge Infrastructure. All databases will be searched from their inceptions to the present without language limitation.

Efficacy and safety of cisplatin for the management of adult patients with oral cancer: A protocol for systematic review.

Background: Cisplatin is often used for the treatment of oral cancer (OC). However, there are inconsistent results. Thus, this study plans to systematically assess the clinical efficacy and safety of cisplatin for adult patients with OC.

lncRNA NORAD Contributes to Colorectal Cancer Progression by Inhibition of miR-202-5p.

Previous study indicates that long noncoding RNA NORAD could serve as a competing endogenous RNA to pancreatic cancer metastasis. However, its role in colorectal cancer (CRC) needs to be investigated. In the present study, we found that the expression of NORAD was significantly upregulated in CRC tissues.

Toll-like receptor 4 gene polymorphism is associated with chronic periodontitis.

Toll-like receptors (TLRs) contribute to the immune response by recognizing patterns presented by bacteria and other pathogens. These receptors have been implicated in the inflammatory response that contributes to gingivitis and periodontitis. Conflicting reports have suggested that variations in the genes encoding TLRs, particularly TLR2 and TLR4, may influence susceptibility to periodontitis.

[Identification of the Mycobacterium tuberculosis complex by detecting recombinant secretory protein MPT64].

Objective: To identify the Mycobacterium tuberculosis complex by detecting the secretory protein MPT64.

Methods: The gene mpt64 was amplified by polymerase chain reaction (PCR) from the genome of Mycobacterium tuberculosis H(37)Rv strain and cloned into expression vector. Immune sera from rabbits by recombinant proteins MPT64, were used to make enzyme-labeled antibodies and coated antibodies.

[Detection on drug resistance of Mycobacterium tuberculosis by microscopic observation drug susceptibility].

Objective: To evaluate the effects of microscopic observation drug susceptibility (MODS) in detecting susceptibility of Mycobacterium tuberculosis (MTB) onto four first line anti-tuberculosis drugs.

Method: The 24-hole cell culture plates were used to test drug susceptibility of MTB on liquid medium, and the best detecting condition of MODS assay was probed; 66 clinical isolates susceptibility to streptomycin (S), isoniazid (H), rifampin (R) and ethambutal (E) were evaluated by using MODS assay and Lowenstein-Jensen (L-J), thereafter, all the inconcordance of isolates between MODS and L-J were tested for the minimal inhibitory concentrations (MIC).

Results: Concordance rate of the susceptibility to S, H, R and E in 66 clinical isolates detected by MODS and L-J was 97.

[Expression and purification of CFP32 of Mycobacterium tuberculosis and its serodiagnostic analysis].

Objective: To establish a recombinant plasmid of CFP32 of Mycobacterium tuberculosis in E. coli, and to analyze its antigenicity.

Methods: Rv0577 gene was amplified by polymerase chain reaction from genome of Mycobacterium tuberculosis, and then cloned into vector pMD18-T followed by the subclone into the expression vector pET21a.
