INTRODUCTION Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries. OBJECTIVE This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats. METHODS We randomly divided eighteen rats into three equal experimental groups: (1) non-treated group; (2) gum tragac...

This paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including Iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). The basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. Viscosity measurements were al...

the aim of this research was to survey of using soy protein isolates and tragacanth gum as egg substitutes in mayonnaise formulation. the mayonnaise prepared with difierent compositions of soy protein isolate, egg, and tragacanth by applying the optimal mixture design method and effect of this substitution on its stability, heat stability, viscosity, texture, physicochemical and sensory charact...

Gum tragacanth is a natural complex mixture of polysaccharides and alkaline minerals extracted from species of Astragalus plant, which is found widely in arid regions of the Middle East. In a pilot experimental study we examined the effects of its topical application on wound healing in ten albino adult male rats. Two similar parasagittal elliptical full-thickness wounds (control vs. test sampl...

In this work, pectin extracts from watermelon rind (WRP) were enzymatically treated to evaluate their potential for preparing hydrogels with the addition of CaCl 2 . Based on a previous two different conditions selected obtain WRP according 1) highest yield (OP) or 2) without negatively affecting branching and native structure (OPA). Firstly, both modified using treatments (de-esterification an...

Four extracellular enzymes of the thermophilic bacterium Clostridium stercorarium are involved in the depolymerization of de-esterified arabinoxylan: Xyn11A, Xyn10C, Bxl3B, and Arf51B. They were identified in a collection of eight clones producing enzymes hydrolysing xylan (xynA, xynB, xynC), beta-xyloside (bxlA, bxlB, bglZ) and alpha-arabinofuranoside (arfA, arfB). The modular enzymes Xyn11A a...

In the wild-type cotton (DP 5690), the cell walls of elongating cotton fibers are bilayered, with the outer layer enriched in de-esterified homogalacturonan (HGA), and an inner layer enriched in xyloglucans and cellulose. This bilayer is conspicuously absent in the cell walls of the ovule epidermal cells and in the fiber of the short fiber mutants Ligon lintless 1 and Ligon lintless 2. The high...

background and objectives: the quality of cakes made of wheat flour depends on the quantity and quality of its gluten proteins however, these proteins may have side effects for some people, including the patients with celiac, and the only way to cure this disease is to take a lifelong gluten-free diet. materials and methods: this research aims to produce gluten- free cake by using rice flour an...
