Cereal β-glucan may be detrimental in pig production because of negative effects on nutrient digestibility, but they may act as functional ingredients by stimulating the intestinal microbiota. This study primarily aimed to investigate relations between dietary β-glucan and nutrient digestibility, intestinal fermentation, and manure NH3 emission in weaned, growing, and finishing pigs. Effects of...

Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...

Glycoside phosphorylases (EC 2.4.x.x) carry out the reversible phosphorolysis of glucan polymers, producing the corresponding sugar 1-phosphate and a shortened glycan chain. β-1,3-Glucan phosphorylase activities have been reported in the photosynthetic euglenozoan Euglena gracilis, but the cognate protein sequences have not been identified to date. Continuing our efforts to understand the glyco...

Three experiments were conducted to investigate the effects of β-glucan supplementation on pig performance and immune function. In Exp. 1, 100 weaned pigs (8.65 ± 0.42 kg of BW and 28 ± 2 d of age) were used in a 35-d experiment to determine the effects of graded levels of β-glucan. Pigs were randomly allotted to 1 of 5 treatments containing β-glucan supplemented at 0, 25, 50, 100, or 200 ppm. ...

objective(s): organic cation transporter 3 (oct3) as a high-capacity transporter contribute to the metabolism of metformin. the present study was conducted to determine the genotype frequencies of the variant oct3-1233g>a (rs2292334) in patients with newly diagnosed type 2 diabetes (t2d) and its relationship with response to metformin. materials and methods: this study included 150 patients wit...

conclusions it can be concluded that the nettle extract can reduce blood glucose levels in diabetic mice, at least partly, by influencing the glut2 gene expression in mice liver. results the results showed that the nettle extract significantly decreased high levels of blood glucose (p < 0.001). the nettle extract also had a preventive effect on decrease in body weight. in addition, the results ...

BACKGROUND An increase in gastrointestinal viscosity or colonic fermentation is suggested to improve appetite control and reduce food intake. It has been proposed that beta-glucan and fructooligosaccharide (FOS) are food ingredients that increase gastrointestinal viscosity and colonic fermentation, but the results are inconclusive. OBJECTIVE The objective was to test the effect of FOS, beta-g...

We investigated the effects of β-glucan purified from Paenibacillus polymyxa JB115 on the viability and proliferation of splenocytes. Splenocytes play a critical role in host immunity. MTT assays and trypan blue exclusion tests revealed that β-glucan significantly promoted the viability and proliferation of splenocytes over a range of concentrations. However, there was no specific subset change...

Hematological and biochemical changes were studied in beluga (Huso huso) weighing 450±50g in the presence of  b,1-3, D-glucan as a single intraperitoneal injection (0.3mg/kg body weight) once, and thereafter a chronic exposure to organophosphate, diazinon at concentration of 1.5 mg/L as a continuous bath for 63 days at 22±1ºC. Results of erythrocyte profile in fish treated with glucan, but with...

A (1→3)-β-D-Glucan produced by Lactobacillus suebicus CUPV221 strain was investigated by tapping mode atomic force microscopy (TM-AFM), to compare its supramolecular structure and conformation with two commercial polysaccharides: curdlan and scleroglucan. It was found that the β-D-Glucan was a (1→3)(1→2)-β-D-Glucan and at room temperature formed three-dimensional networks by entanglements betwe...
