A yeast strain MJ2 that was found to produce a higher amount of γ-aminobutyric acid (GABA) was isolated from the surface of kiwi. Phylogenetic analysis based on the ITS sequence and morphological, biochemical studies indicated that it may belong to Saccharomyces cerevisiae. Under optimum conditions in Czapek’s broth medium with 0.5 % monosodium glutamate,(More)
The purpose of this study was to evaluate the effect of grape seed procyanidin (GSPE) fractions with different degrees of polymerisation (DPs) on blood glucose, lipids and hepatic oxidative stress in diabetic rats. Diabetic rats received a daily oral supplement of GSPE with different DPs for 6 weeks. During this period, blood glucose, body weight and food(More)
The proportion of foodborne disease caused by pathogenic microorganisms is rising worldwide, with staphylococcal food poisoning being one of the main causes of this increase. Juglone is a plant-derived 1,4-naphthoquinone with confirmed antibacterial and antitumor activities. However, the specific mechanism underlying its antibacterial activity against(More)
BACKGROUND Cluster of differentiation 44 (CD44) is a family of transmembrane glycoproteins. As cell surface hyaluronate receptor, it has been found to be widely expressed in a variety of cells. The aim of this study is to assess the relationship among CD44 expression, DNA content, proliferation index (PI) and apoptosis in female adenocarcinoma of the lung.(More)
In this article, we give some conditions on the structure of an unstable module, which are satisfied whenever this module is the reduced cohomology of a space or a spectrum. First, we study the structure of the sub-modules of ΣsH̃∗(B(Z/2)⊕d;Z/2), i.e., the unstable modules whose nilpotent filtration has length 1. Next, we generalise this result to unstable(More)
Juglone is a plant-derived 1,4-naphthoquinone with confirmed antibacterial activity. However, the mechanism of action of juglone against Staphylococcus aureus remains unclear. Possible mechanisms were explored by a proteomic analysis of S. aureus proteins that are inhibited by juglone. Two-dimensional gel electrophoresis revealed that 21 protein spots were(More)
Cu-doped zinc oxide and its polythiophene nanocomposites were prepared by the Sol-Gel and in situ polymerization methods, respectively. The structures, morphologies and compositions of the samples were characterized. The antibacterial properties of the samples on three kinds of strains were determined by using powder inhibition zones, minimum inhibitory(More)
The cytogenetic toxicity of rhodamine B on root tip cells of Allium cepa was investigated. A. cepa were cultured in water (negative control), 10 ppm methyl methanesulfonate (positive control), and three concentrations of rhodamine B (200, 100, and 50 ppm) for 7 days. Rhodamine B inhibited mitotic activity; increased nuclear anomalies, including micronuclei,(More)
In the present work, alkali extraction technology was used to optimize the extraction of Monascus mycelium polysaccharides for the first time. The extracting parameters of alkali extracted Monascus mycelium polysaccharides were optimized by Box-Behnken design (BBD). The optimum conditions were extraction temperature 49 °C, alkali concentration 7%,(More)
