Genetic polymorphisms in the gene influenced HIV-1 infection in a Yunnan population.

Background: Due to the deficiencies of vaccines and effective medicine, the human immunodeficiency virus (HIV) infection mechanism should be studied. The gene, one of the interferon-stimulated genes (ISGs), expresses broad-spectra anti-viral activity, including inhibiting HIV replication.

Methods: In this study, we collect 421 HIV-1 infected patients and 448 controls to genotype three SNPs in the gene.

Characterization of a Novel Hepatitis C Subtype, 6xj, and Its Consequences for Direct-Acting Antiviral Treatment in Yunnan, China.

Hepatitis C virus (HCV) has a high rate of genetic variability, with eight genotypes and 91 subtypes. The genetic diversity of HCV genotype 6 (HCV-6) is the highest with 31 subtypes, and this genotype is prevalent in Southeast Asia. In this study, we investigated 160 individuals with chronic hepatitis C in Yunnan Province, China.

Environment-Friendly Preparation of Reaction-Bonded Silicon Carbide by Addition of Boron in the Silicon Melt.

Reaction-bonded silicon carbide ceramics were sintered by infiltration of Si and B-Si alloy under an argon atmosphere at different temperatures. The element boron was added to the silicon melt to form a B-Si alloy first. The mechanical properties of samples were improved by infiltration of the B-Si melt.
