In this study, two novel antibacterial peptide genes, termed lugensin A and B were identified and characterized from a rice sap-sucking hemipteran insect pest, the brown planthopper, Nilaparvata lugens. Lugensin gene expression was significantly induced by Gram-negative and Gram-positive bacterial stains under the regulation of a signal receptor, the long peptidoglycan recognition protein (PGRP-LC...
Cadmium (Cd) is a highly toxic pollutant and a nonessential element for plant growth. Here, we investigated the levels of malondialdehyde (MDA), H2O2, sugars, and the activity and gene expression of antioxidant enzymes and sugar metabolism related enzymes in the mycelia of Pleurotus eryngii grown in the presence of 0, 0.5, 1, 1.5, 2.0, and 4.0 mg·L-1 Cd. Raising Cd concentration resulted in...
Objective To detect the profile of 114 microRNA (miRNA) expression in hepatocellular carcinoma and investigate the relationship of miR-338 expression with clinicopathological parameters.
Method A bead-based miRNA expression profiling method was performed on 20 pairs of surgically removed HCC and adjacent non-tumorous tissue (NT). Special miR-338 downregulations and miR-338 associated with clini...
We used the traditional hydro-thermal synthesis method to generate the first photochromic pyrimidinium/polyoxometalate (POM) salt material (C4N2H4–C4N2H3) [Mn(H2O)6]0.5{SiW12O40}0.5ˑ5H2O in situ by using silicotungstic acid and pyrimidine as raw materials. The solid UV diffuse reflectance spectrum of compound 1 was shifted before and after illumination. There was a new broad absorption peak appea...
Objective To test the expression levels and significance of peroxisome proliferator-activated receptor gamma(PPARγ) and PTEN protein in hepatocellular carcinoma(HCC) tissues and adjacent non-tumor liver tissues, and investigate the relationship of both proteins expression with clinicopathological parameters.
Method One hundred of tumor tissues and surrounding liver tissues were collected from p...
The objective of the study is to establish a model between the impedance characteristics and the sugar content of internal quality index of melons. The equivalent series resistor and equivalent series capacitor of melon are measured over the frequency from 1 KHz to 100 KHz by a LCR meter and an airtight shielding case. Then the impedance is calculated. Through principal component analysis (PCA), f...

Modular reconfigurable robotics system is an approach to building robots for various complex tasks. Modular reconfigurable robots show the promise of great versatility, robustness and low cost. They can be used extensively to meet the demands of different tasks or different working environments. They can change their shapes, such as from snake first to loop and next to quadruped and so on. Therefo...
OBJECTIVE To investigate the effect of 15-deoxy-Delta(12,14)-prostaglandin J(2) (15-d-PGJ(2)) on the anoikis of hepatocellular carcinoma (HC) cells and mechanisms thereof.
METHODS Fibronectin or polyhydroxyethyl methacrylate (poly-HEMA) were coated onto tissue culture plates, cell growth status and morphological changes were detected by optical microscope. DNA fragmentation analysis and Flow cyt...
