Alanine aminotransferase is more sensitive to the decrease in hepatitis B virus-DNA load than other liver markers in chronic hepatitis B patients.

Background: A direct correlation between hepatitis B virus DNA (HBV-DNA) and liver markers has not been identified in chronic hepatitis B (CHB) patients. However, the effect of HBV-DNA changes on liver markers remains unclear. We explored the association between decreased HBV-DNA and liver makers in CHB patients.

Association of Rs11615 (C>T) in the excision repair cross-complementing group 1 gene with ovarian but not gynecological cancer susceptibility: a meta-analysis.

Background: Evidence suggests that the rs11615 (C>T) polymorphism in the ERCC1 gene may be a risk factor for gynecological tumors. However, results have not been consistent. Therefore we performed this meta- analysis.

Molecular cloning, sequence analysis and expression of a GHF 43 xylanase from Aspergillus niger in Escherichia coli.

A new xylanase gene (xyn43A) from Aspergillus niger XZ-3S was cloned and expressed in Escherichia coli BL21-CodonPlus (DE3)-RIL. The coding region of the gene was separated by only one intron 86 bp in length. It encoded 318 amino acid residues of a protein with a calculated molecular weight (MW) of 33.
