A room temperature nitric oxide gas sensor based on a copper-ion-doped polyaniline/tungsten oxide nanocomposite.

The parts-per-billion-level nitric oxide (NO) gas sensing capability of a copper-ion-doped polyaniline/tungsten oxide nanocomposite (Cu(2+)/PANI/WO3) film coated on a Rayleigh surface acoustic wave device was investigated. The sensor developed in this study was sensitive to NO gas at room temperature in dry nitrogen. The surface morphology, dopant distribution, and electric properties were characterized using scanning electron microscopy, energy-dispersive X-ray spectroscopy mapping, and Hall effect measurements, respectively.

Complete mitochondrial genome of the Xiangjiang barbel chub Squaliobarbus curriculus: comparative analysis of the genetic variation associated with geographical population.

The barbel chub (Squaliobarbus curriculus), a kind of small commercial fish, is widespread in China. In this study, we sequenced the mitochondrial genome of the barbel chub from the Xiangjiang River. The total length of the mitochondrial genome is 16,619 bp, with the base composition of 31.

Mitochondrial DNA sequence of the hybrid of Squaliobarbus curriculus (♀) × Ctenopharyngodon idella (♂).

In this work, we reported the complete mitochondrial DNA sequence of the hybrid of Squaliobarbus curriculus (♀) × Ctenopharyngodon idella (♂), which was obtained by artificial hybridization. The total length of the mitochondrial genome is 16,616 bp, with the base composition of 31.15% A, 25.

The complete mitochondrial genome of the hybrid of Ctenopharyngodon idella (♀) × Squaliobarbus curriculus (♂).

The complete mitochondrial genome sequence of the hybrid of Ctenopharyngodon idella (♀) × Squaliobarbus curriculus (♂) was determined using PCR-based method. The total length of the mitogenome is 16,609 bp. It contains the typical structure as that of most other vertebrates, including 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and 1 non-coding control region (D-loop region).

[Literature research of the hepatotoxicity of glucoside tripterygium total and its synergism and toxicity reducing effects].

Correlated literatures of the liver injury induced by glucoside tripterygium total (GTT) and of its synergism and toxicity reducing effects were retrieved to study the correlation between the dosage, the time point of GTT and the liver injury. The monomer or active ingredients of animals and plants with the hepatoprotective effect were included. The mechanisms of action between GTT and these drugs were analyzed.

Down-regulation of PTEN expression due to loss of promoter activity in human hepatocellular carcinoma cell lines.

Aim: To investigate the regulation of phosphatase and tensin homolog deleted on chromosome ten (PTEN) gene expression in human hepatocellular carcinoma (HCC) cell lines.

Methods: The mRNA and protein levels of PTEN were detected by Northern blot and Western blot in HCC cell lines, respectively. Plasmids containing different fragments of PTEN promoter with Luciferase reporter were constructed and transiently transfected into HCC cell lines to study the promoter activity.
