Background: Mucilage is an important polysaccharide with a broad range of physicochemical properties and antioxidant activity that widely used for various applications in the medicine food industries. Objectives: This study aims to evaluate effect extraction method on mucilage extracted from yellow brown flaxseeds. Methods: was by different methods: heating, sonotrode, bath sonication. The eval...

Rapidly developing field of nanobiotechnology dealing with metallic nanoparticle (MNP) synthesis is primarily lacking control over size, shape, dispersity, yield, and reaction time. Present work describes an ecofriendly method for the synthesis of silver nanoparticles (AgNPs) by cell free extract (CFE) of Saccharomyces boulardii. Parameters such as culture age (stationary phase growth), cell ma...

Nanoscale control of structure in polymer nanocomposites is critical for their performance but has been difficult to investigate systematically due to the lack of a suitable experimental model. In this work, we investigated the role of nanoparticle layer separation in the finite deformation response of layered polyurethane(PU-) montmorillonite (MTM) nanocomposites. A series of multilayered nano...

Background and aim: Improvement of wound healing in normal subjects and in chronic ulcers has been always desired. The availablity and acceptability of herbal medicine led us to study the effect of topical 10% mucilage of quince seed in human skin.Materials and Methods: This double-blind clinical trial has been conducted on 34 patients referring to Imam Hospital, clinic...

Pectins are complex polysaccharides that form the gel matrix of the primary cell wall and are abundant in the middle lamella that holds plant cells together. Their degree of methylesterification (DM) impacts wall strength and cell adhesion since unesterified pectin regions can cross-link via Ca(2+) ions to form stronger gels. Here, we characterize flying saucer1 (fly1), a novel Arabidopsis thal...

A study was carried out to determine the influence of mucilage viscosity on the globule structure (i.e. size and number) of certain starch emulsions. The starches investigated were cassava, potato and maize. The emulsions were prepared by mixing the starch mucilage of a predetermined concentration 4%w/v with arachis oil in the ratio 50:50, using a silverson mixer fitted with a dispersator head....

With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. Moreover, the tremendous orientation of pharma world towards these naturally derived polymers has become a subject of increasing interest to discover, extract and purify such compounds from the reported origin. In the present review we have discussed muc...

In tracing the biological processes using fluorescent probes, it is desirable to shift the excitation/emission energy to a far-red/near-infrared (FR/NIR) region. In this study, we successfully synthesize FR fluorescent organic nanoparticles via ion-association between the malachite green (MG) cations and tetrakis(4-fluorophenyl)borate (TFPB) anions in the presence of a neutral stabilizing polym...

In this study the rheological and textural properties of Iranian white cheese produced by ultrafiltration technique containing gum tragacanth and xanthan gum each in the range of 0-0.1%, and basil seed and linseed mucilages each in the range of 0-0.2% were evaluated. According to the results obtained, values of Elastic (G/) and viscous (G//) moduli increased with increasing frequency sweep in a...

Size-controlled ZnSe nanoparticles with high extents of atomic positional order are shown to exhibit large size-dependent variations in their local electronic environments. Solid-state ;{77}Se and ;{67}Zn NMR spectra reveal increasingly broad distributions of ;{77}Se and ;{67}Zn environments with decreasing nanoparticle sizes, in contrast with high degrees of atomic positional order established...
