Antibiotic exposure in early life can lead to a significant change of the gut microbiota and may contribute to later onset of inflammatory bowel disease (IBD). However, the relationship between early-life antibiotic treatment and IBD is ambiguous, according to contradicting results of epidemiologic studies. In the present study, we demonstrated that(More)
A new biotransformation method of producing resveratrol with co-immobilized edible Aspergillus niger and Yeast (AY) was investigated. The biotransformation conditions were optimized for the resveratrol production under 30 °C, pH 6.5, 2 days, liquid-solid ratio 12:1 (mL/g), the yield of resveratrol reached 33.45 mg/g, which increased 11-fold to that of(More)
OBJECTIVE Dietary factors have been indicated to influence the pathogenesis and nature course of inflammatory bowel diseases (IBD) with their wide variances. The aim of the study was to assess the prevalence and clinical significance of 14 serum food specific immunoglobulin G (sIgG) antibodies in patients with IBD. METHODS This retrospective study(More)
An aqueous solution containing sodium polyacrylate (PA, 0.0030M) was used in diffusive gradients in thin-films technique (DGT) to measure DGT-labile Cu(2+) and Cd(2+) concentrations. The DGT devices (PA DGT) were validated in four types of solutions, including synthetic river waters containing metal ions with or without complexing EDTA, natural river water(More)
In this study, sophoricoside from Fructus sophorae was highly bioconversed to genistein by co-immobilized Aspergillus niger and Yeast. Bioconversion conditions for genistein were optimized with single-factor experiments. The optimal conditions were as follows: microbial concentration 1.5 × 10(7) cells/mL, wet weight of microorganisms beads 10.0 g/g(More)
Pigeon pea is an important and multiuse grain legume crop, and its leaves are a very valuable natural resource. To obtain a high-quality biological resource, it is necessary to choose the excellent cultivar and determine the appropriate harvest time. In this study, the variation in contents of main active components and antioxidant activity in leaves of six(More)
In the present study, antimicrobial activity and mode of a novel synthesized pyrrolizidine alkaloid (PA-1) were investigated. PA-1 exhibited predominantly strong antibacterial activity toward six bacteria tested with minimal inhibitory concentration (MIC) values ranging from 0.0039 to 0.025 mg ml(-1). The time-kill assay indicated that PA-1 killed(More)
BACKGROUND AND AIMS The interplay between luminal microbes and innate immunity during colonic epithelial repair has been well noted. At the same time, antibiotic has widely been used during flare-ups of ulcerative colitis. The possible effects of luminal microbiota disruption caused by antibiotics usage on epithelial repairing have been scarcely discussed.(More)
A novel and effective extraction method, namely negative pressure cavitation-microwave assisted extraction technique (NMAE), was developed for the preparation of extracts of Pyrola incarnata Fisch., which are rich in the main constituents hyperin, 2'-O-galloylhyperin and chimaphilin. Single factor experiments and Box-Behnken design (BBD) were combined with(More)
