DNA ladder fragments, regarded as a biochemical hallmark of apoptosis, have been separated quickly and successfully by capillary electrophoresis. Inter-nucleosomal DNA fragmentations induced by xylitol selenite were determined for the first time, while hydroxypropylmethylcellulose (HPMC) was served as the sieving matrix in dynamic sieving capillary(More)
The root of Rubia cordifolia has been used traditionally as a hemostatic agent, while the aerial part of the plant consisting of leaf and stem is known to exhibit anti-diarrheal properties and has been widely used as a remedy in many parts of China. As rotavirus is one of the most commonly associated diarrhea-causing pathogen, this study aims to investigate(More)
To determine the glutathione (GSH) content in a human hepatoma cell line (SMMC-7221) treated with xylitol/selenite, providing a part of an investigation of its anti-cancer mechanisms. The nuclei of SMMC-7221 cells were stained with Hoechst 33258 in an apoptosis assay, and their morphology subsequently changed from circular to crescent shape. The calibration(More)
BACKGROUND Actinobacillus pleuropneumoniae, a Gram-negative bacterium, is the causative agent of porcine pleuropneumonia, a highly contagious and often fatal disease. Because current vaccines confer limited protection against A. pleuropneumoniae infection, the development of more effective vaccines is urgently required. The identification of immunogenic and(More)
A scaffold provides a framework and initial support for the cells to attach, proliferate and differentiate, and form an extracellular matrix (ECM) in tissue engineering. Here, xyloglucan (XG) was used as a new synthetic ECM for HepG2 cell attachment in alginate capsules. The effects of XG on HepG2 cells on adherent behavior, albumin secretion, ammonia(More)
