Lactose (1,4-O-beta-d-galactopyranosyl-d-glucose) is a soluble and economic carbon source for the industrial production of cellulases or recombinant proteins by Hypocrea jecorina (anamorph Trichoderma reesei). The mechanism by which lactose induces cellulase formation is not understood. Recent data showed that the galactokinase step is essential for cellulase induction by lactose, but growth on...
BACKGROUND/AIM To determine the phenolic acid levels and DNA damage protection potential of Capparis spinosa L. seed extract and to investigate the effect of the extract on cognitive impairment and oxidative stress in an Alzheimer disease mice model. MATERIALS AND METHODS Thirty BALB/c mice divided into 5 groups (control, D-galactose, D-galactose + C. spinosa 50, D-galactose + C. spinosa 100,...
PURPOSE The purpose of this study was to evaluate the role of exendin-4 on reproductive alteration in a D-galactose-induced aging mouse model. MATERIALS AND METHODS In this experimental study, 72 male Naval Medical Research Institute mice (20~25 g) were randomly divided into six groups: control, exendin-4 (1 nmol/kg), exendin-4 (10 nmol/kg), D-galactose (500 mg/kg), D-galactose+exendin-4 (1 n...
D-(+)-Galactose-conjugated single-walled carbon nanotubes (SWCNTs) were synthesized for use as biosensors to detect the cancer marker galectin-3. To investigate the binding of galectin-3 to the d-(+)-galactose-conjugated SWCNTs, an electrochemical biosensor was fabricated by using molybdenum electrodes. The binding affinities of the conjugated SWCNTs to galectin-3 were quantified using electroc...
BACKGROUND Aging is associated with the loss of endocrine function. In this study, Vitex agnus-castus (Vitex), which has antioxidant effects and high levels of phytoestrogen, was investigated with regard to the hypothalamic-pituitary-gonadal axis and antioxidant indices in natural aging and in a d-galactose induced aging model in female mice. METHODS The mice were subcutaneously injected with...
Background: Increased oxygen free radical and reduced glutathione level in the eye lens are important risk factor for cataract formation. The antioxidative property and increasing cellular and extra cellular glutathione level have been reported by several herbal medicines including silymarin. Objective: In present interventional study Silybum marianum L. seed extract (silymarin) was tested a...
In Aspergillus nidulans, the xylanolytic regulator XlnR and the arabinanolytic regulator AraR co-regulate pentose catabolism. In nature, the pentose sugars D-xylose and L-arabinose are both main building blocks of the polysaccharide arabinoxylan. In pectin and arabinogalactan, these two monosaccharides are found in combination with D-galactose. GalR, the regulator that responds to the presence ...
