AIMS To evaluate the free radical-scavenging capacity of Lactobacillus fermentum and its effects on antioxidant enzyme levels in finishing pigs. METHODS AND RESULTS The free radical-scavenging activity of Lact. fermentum was analysed in vitro. The tested Lactobacillus showed a high scavenging ability against DPPH (1,1-diphenyl-2-picrylhydrazyl),(More)
This study investigates the extent of apoptosis in complete hydatidiform mole (CHM), using an in situ 3'-end DNA labelling (TUNEL) technique on formalin-fixed and paraffin-embedded sections. The sections were also immunostained with antibodies to p53, Bax and Bcl-2 proteins. In 10 normal placenta cases and 15 CHM cases, the apoptotic index was <1 and 2-4(More)
AIMS To investigate the adhesion of lactobacilli and their subsequent competitive exclusion ability against pathogens. METHODS AND RESULTS Four species of putative probiotic lactobacilli were studied for their adhesion abilities. First, the adhesion to Caco-2 cells was examined by light and electron microscopy. The four species were then labelled by(More)
It is well known that β-conglycinin, a soybean allergen, induces allergies and causes intestinal damage in fetuses and neonates. However, the underlying mechanisms responsible for the adverse effects of β-conglycinin remain elusive. In particular, it is unknown whether or not this dietary substance causes direct damage affecting the proliferation and(More)
AIM To investigate the structures and immunomodulation activity of four homogeneous polysaccharides: LBP 1a-1, LBP 1a-2, LBP 3a-1 and LBP 3a-2 isolated from Lycium barbarum L. brought from Zhongning County, Ningxia Province. METHODS Their molecular weights, sugar component (constituents) and their linkages were determined by gel permeation chromatography,(More)
Leptin plays a critical role in regulating muscle protein metabolism by binding with leptin receptors in a 1:1 stoichiometry. However, the role for leucine in the regulation of leptin receptor expression in muscle has not been investigated. The present study was conducted to test the hypothesis that leucine regulates leptin receptor levels in C2C12(More)
Probiotics are living microorganisms that provide a wide variety of health benefits to the host when ingested in adequate amounts. The bacterial strains most frequently used as probiotic agents are lactic acid bacteria, such as Lactobacillus reuteri, which is one of the few endogenous Lactobacillus species found in the gastrointestinal tract of vertebrates,(More)
Antibiotics have long been used in animal production and medication to alleviate weaning stress. However, due to the concerns over food safety and human health, its use in animal production has been prohibited in many countries. Therefore, there is growing interest in developing alternative additives, such as a probiotic Lactobacillus. In this study, a(More)
Postweaning diarrhea is one of the most common causes of morbidity and mortality in weanling piglets. Feeding sodium butyrate to weanling piglets decreased the incidence of diarrhea, but the mechanism has not been fully elucidated. The present study was to evaluate the effect of sodium butyrate on diarrhea in relation to wound healing of intestinal barrier(More)
Nutritional induction of endogenous antimicrobial peptide expression is considered a promising approach to inhibit the outgrowth and infection of pathogenic microbes in mammals. The present study investigated possible regulation of porcine epithelial β-defensins in response to branched-chain amino acids (BCAA) in vivo and in vitro. BCAA treatment increased(More)
