AgNPs-Tragacanth conjugate gel as an eco friendly and low cost membrane was applied for the effective electromembrane extraction (EME) of Tenofovir disproxil fumarate, an important acidic and high polar (log p=1.25) antiviral drug, followed by HPLC-UV determination. The effect of various parameters on the extraction efficiency including the presence of AgNPs, tragacanth gum concentration, gel t...

Nanoparticles or microparticles created by physical complexation between two polyelectrolytes may have a prospective use as an excipient for oral insulin administration. Natural polymers such as tragacanth, alginate, dextran, pullulan, hyaluronic acid, gelatin and chitosan can be potential candidates for this purpose. In this research, insulin particles were prepared by the inclusion of insulin...

In present study, two kinds of thermal power plant ashes; one the fly ash and the other waste ash are mixed with adhesive tragacanth and cement to produce new composite materials. 48 new samples are produced by varying the percentages of the fly ash, waste ash, cement and tragacanth. The new samples are subjected to some tests to find out their properties such as thermal conductivity, compressi...

BACKGROUND AND THE PURPOSE OF THE STUDY Extrusion-spheronization is an established technique for the production of pellets for pharmaceutical applications. In this study, the feasibility and influence of the incorporation of acacia, by itself and in combination with tragacanth, on the ability of formulations containing 2 model of drugs (ibuprofen and theophylline) to form spherical pellets by e...

Date syrup as a nutritional additive and safe alternative to added sugar is one of the best choices for milk flavoring. In this study, a flavored milk beverage was formulated using date syrup for flavoring the product and gum tragacanth to obtain an acceptable mouth feel. Steady shear and dynamic oscillatory rheological properties of the samples contained 3 concentrations (0, 0.1, 0.2, and 0.3%...

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...

Silver nanoparticles (AgNPs) are being widely applied as topical wound materials; however, accumulated deposition of silver in the liver, spleen, and other main organs may lead to organ damage and dysfunction. We report here that low molecular weight chitosan-coated silver nanoparticles (LMWC-AgNPs) are effective against methicillin-resistant Staphylococcus aureus (MRSA), have better biocompati...
