Vibrio parahaemolyticus, a marine pathogen, is a causative agent of gastroenteritis in humans after consumption of contaminated seafood. In recent years, infections with V. parahaemolyticus have become an increasingly frequent factor in microbial food poisoning; therefore, it is urgent to figure out ways to control Vibrio parahaemolyticus. Endolysins, lytic(More)
Heat stress (HS) damages the global dairy industry by reducing milk yields and quality, harming health, and damaging the reproduction of dairy cows, causing huge economic losses each year. However, an understanding of the physiological mechanism of HS lactating dairy cows remains elusive. Here, a metabolomics study using LC-MS and (1)H NMR spectroscopy was(More)
Controlling heat stress (HS) is a global challenge for the dairy industry. In this work, an integrated metabolomics and lipidomics approach using (1)H nuclear magnetic resonance (NMR) and ultra-fast LC-MS in combination with multivariate analyses was employed to investigate the discrimination of plasma metabolic profiles between HS-free and HS lactating(More)
Liver-directed gene therapy has become a promising treatment for many liver diseases. In this study, we constructed a multi-functional targeting molecule, which maintains targeting, endosome-escaping, and DNA-binding abilities for gene delivery. Two single oligonucleotide chains of Melittin (M) were synthesized. The full-length cDNA encoding anti-hepatic(More)
Gene therapy with nonviral vectors using the suicide gene/prodrug activating system of herpes simplex vi-rus type-1 thymidine kinase (HSV1-TK)/ganciclovir (GCV) is inefficient in killing malignant tumor cells due to two major factors: (a) an unsatisfactory by-stander effect; (b) short-lived expression of the pro-tein. To study the capacity of the protein(More)
This study was designed to evaluate the effect of oral administration of ginseng stem-and-leaf saponin (GSLS) on immune responses in chickens vaccinated with live Newcastle disease (ND) vaccines. In experiment 1, chickens were orally administered GSLS (2.5, 5, 10, and 20mg/kg) in drinking water for 3 days, and then intranasally vaccinated with ND vaccine.(More)
Hepatocellular carcinoma (HCC) is one of the most malignant and lethal human cancers. Epithelial-mesenchymal transition (EMT) enhances the carcinogenesis of HCC, and therapies targeting EMT appear to be promising treatments. We have previously shown that Krüppel-like factor 4 (KLF4) suppressed EMT of HCC cells through downregulating EMT-associated proteins.(More)
The fast separation capability of a capillary electrophoresis with electrochemical detection (CE-ED) system was demonstrated by determining five beta-agonists including clenbuterol, metoprolol, ractopamine, isoxsuprine and salbutamol in several real samples. Factors influencing the separation and detection were examined and optimized. Under the optimum(More)
AIMS AND BACKGROUND In the present study, we evaluated the value of computed tomography-guided 125I implantation for malignant osseous tumors. METHODS Under computed tomography guidance, 125I seeds were implanted into malignant osseous tumors of 19 patients. The curative effect was evaluated according to the degree of ostealgia relief and the changes in(More)
A new high-efficiency transformless photovoltaic generation system, which is based on singlephase hybrid clamped three-level inverter, is proposed in this paper. The leakage current problem in transformless photovoltaic generation systems is solved. The elimination of the transformer can not only reduce the cost, size and weight of the conversion stage, but(More)
