the increasing tendency for health oriented products caused considerable research has studied on increase and maintaining quality of different products. sponge cake is one of the cereal products which itsmain problems arereterogradation and lack of soluble dietary fibers which has many health benefits. in this research, therefore, the effects of adding oat β-d-glucan on the physical properties ...

Four new steroidal glycosides such as 3-O-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 → 4)-β-D-oleandropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside-12-β-tigloyl-14-β-hydroxy-17-β-pregnane (1), 3-O-6-deoxy-3-O-methyl-β-D-allopyranosyl-(1 → 4)-β-D-oleandropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside-12-β-(2'-amino)-benzoyl-14-β-hydroxy-17-β-pregnane (2), 3-...

ba c k g r o und : the aim of this study was to examine the association between dietary intakes of vitamin d and the metabolic syndrome (mets) in tehranian adults, iran. m ethods : in this population-based prospective study, a sample of 2357 subjects, aged 20-74 years, who had completed a validated food frequency questionnaire, were  studied.  mets  was  defined  according to  the  modified  gu...

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...

Purification of a MeOH extract from the aerial parts of Hylomecon vernalis Maxim. (Papaveraceae) using column chromatography furnished a new acetylated flavonol glycoside (1), together with twenty known phenolic compounds (2-21). Structural elucidation of 1 was based on 1D- and 2D-NMR spectroscopy data analysis to be quercetin 3-O-[4‴-O-acetyl-α-L-arabinopyranosyl]-(1‴→6″)-β-D-galactopyranoside...

In this paper, we investigate new solutions to the Rhoades' discontinuity problem on existence of a self-mapping which has fixed point but is not continuous at metric spaces. To do this, use number defined as n(x,y)=[d(x,y)]β[d(x,Ty)]α[d(x,Ty)]γ[(d(x,Ty)+d(x,Ty))/2]1−α−β−γ, where α , β γ ∈ ( 0,1 ) with + < 1 and some interpolative type contractive conditions. Also, geometric properties Fix(T...

Protein dynamics play a significant role in many aspects of enzyme activity. Monitoring structural changes and aggregation biotechnological enzymes under native conditions is important to safeguard their properties function. In this work, the potential asymmetrical flow field-flow fractionation (AF4) study dynamic association equilibria β-D-galactosidase (β-D-Gal) was evaluated. Three commercia...

The work aimed to improve the extraction efficiency of wheat bran polysaccharide by solid-state fermentation using bioactive fungus Isaria cicadae Miq. and identify structural properties fermented (IC-FWBP). fraction IC-FWBP was isolated with an yield 2.88% average molecular weight 3.31 × 106 Da. comprised mannose, glucose, galactose. methylation, nuclear magnetic resonance (NMR), Congo red ana...
