Crude water-soluble polysaccharides (BRP) were extracted from the root of Brassica rapa L. using boiling-water. The polysaccharides were successively purified by chromatography on DEAE-cellulose and Sephadex G-100 column, giving three major polysaccharide fractions termed BRP1-1, BRP2-1, BRP3-1. The
The facilitated diffusion system for monosaccharides was studied with nonmetabolized 3-O-methyl-D-glucose (3-O-MG) and hexokinase activity was determined with 2-deoxyglucose (2-DG) in extensor digitorum longus (EDL) and soleus muscles from BIO 14.6 (dystrophic) hamsters. Motor activity was recorded
Three kinds of new water-soluble polysaccharides (FA, FB and FC) were isolated from wild mushroom Agaricus bitorquis (Quél.) Sacc. Chaidam by the classical method "water extraction and alcohol precipitation" and purified by column chromatography. The Mw of FA, FB and FC ranged from
Molecular mechanisms mediating the induction of metal ion homeostasis-related genes in the mammalian intestine during iron deficiency remain unknown. To elucidate relevant regulatory pathways, genomewide gene expression profiles were determined in fully differentiated human intestinal epithelial
1. The effects of monosaccharides, glycolytic intermediates, metabolic inhibitors and anxia, have been studied on the membrane electrical activity of mouse pancreatic islet cells in vitro using a single intracellular micro-electrode for both voltage recording and current injection. 2. In addition to
Using a new, in vitro, experimental approach the transport of glucose, galactose, fructose and glycine in seroso-mucosal direction in the small intestine, was studied under different modes of oxygenation. In case of monosaccharides under the oxygenation from serosal surface, the substrate
Hypoxia modulates the production of key inflammation-related adipokines and may underlie adipose tissue dysfunction in obesity. Here we have examined the effects of hypoxia on glucose transport by human adipocytes. Exposure of adipocytes to hypoxia (1% O(2)) for up to 24 h resulted in increases in
The penetration of a nonmetabolized glucose analogue, 3--O-methyl-D-glucose, across the plasma membranes of tissues from dystrophic mice and cardiomyopathic (dystrophic) hamsters has been compared with that of normal controls. Under basal conditions the penetration of test sugar was similar in lens
Objective
To examine the expression of
hypoxia-inducible factor-1
α (HIF-1
α), TfR1, and TfR1-attached terminal
monosaccharides in placentas of women with IDAP and severe preeclampsia.
Methods
TfR1 and HIF-1
α were detected by western
To study the interdependence of sucrose accumulation and its hydrolyzing enzyme, soluble acid invertase (AI; EC 3.2.1.26), in fructan-accumulating temperate grasses and cereals, experiments were performed in which sucrose synthesis was abolished in leaves of Lolium temulentum by four independent
The transport of glucose, other monosaccharides and disaccharides in the rat small intestine has been studied under the condition of a predominance of serosal-to-mucosal (SM) flows over mucosal-to-serosal (MS) ones. A dependence has been found of the efflux of glucose into the serosal solution on
Every cell needs energy, i.e., adenosine triphosphate (ATP), to carry out its function. Decreased oxygen levels, decreased blood flow, and other stressful conditions can drastically effect the intracellular concentrations of these energy compounds. Skeletal muscle, unlike the heart, can address this
1. The effect of various monosaccharides on the potential difference across the intestine of the invertebrate, Cryptochiton stelleri, was studied using an everted sac technique.2. D-Glucose, when present in the mucosal solution, increased the transmural potential across the anterior intestine but
With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange) Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent
BACKGROUND
The fruits of Hippophae rhamnoides L., Lycium barbarum L., Lycium ruthenicum Murr. and Nitraria tangutorum Bobr. are traditional medicinal food of Tibetans and used to alleviate fatigue caused by oxygen deficiency for thousands of years. The present study focused on exploiting natural
