Association of total oxidant status, total antioxidant status, and malondialdehyde and catalase levels with psoriasis: a systematic review and meta-analysis.

Although oxidative stress plays a major role in psoriasis, the association between oxidative stress biomarker levels and psoriasis in humans remains controversial. Relevant articles were retrieved by searching the following databases: PubMed, Web of Science, and EMBASE, without any time limit (updated March 10th, 2019). The pooled weighted mean difference (WMD) and 95% confidence interval (CI) for the total oxidant status (TOS), total antioxidant status (TAS), malondialdehyde (MDA), and catalase (CAT) were calculated for each study.

Study on the Fluorescent Activity of N²-Indolyl-1,2,3-triazole.

A new type of blue emitter, ²-Indolyl-1,2,3-triazoles (NITs), with the λ ranging from 420-480 nm and the Stokes shift from 89-143 nm, were synthesized through the coupling reaction of indoles with triazole derivatives. The influence of different substitution patterns on the optical properties (efficiency, excitation, and emission wavelengths) of the NITs was investigated. In addition, one palladium complex were synthesized by using NITs as the ligands, which, however, exhibited no fluorescent activity, but did show the enhanced co-planarity.

[Construction of plant expression vectors with PMI gene as selection marker and their utilization in transformation of Salvia miltiorrhiza f. alba].

Objective: To construct plant expression pCAMBIA1301-PMI by substituting PMI for hygromycin resistance gene in pCAMBIA1301 and obtain transgenic Salvia miltiorrhiza f. alba using PMI-mannose selection system.

Method: The 6-phosphomannose isomerase gene (PMI) of Escherichia coli was amplified by PCR.
