A surface active layer consisting mainly of phospholipids lines the human conducting airways. Dysfunction of this layer could play a role in the pathogenesis of chronic obstructive airway diseases like asthma and chronic bronchitis. Replacement therapy with exogenous surfactants is being considered in such conditions. The relationship between surfactants and mucus viscosity would be important f...

plants gums, hydrophilic colloids, hydrocolloids, mucilages and hydrophilic polymers are compounds that can produce gel. coating materials which applied on food products increased shelf life of food by affecting water loss, gas exchange, oxidation process and decreasing the food spoilage and affect shelf life of food products. coating material could carry antioxidant, antibacterial and/or other...

Poly(butylene succinate) (PBSU) is a biodegradable and biocompatible synthetic aliphatic polyester, which has been used extensively in packaging, catering agriculture, more recently drug delivery bone cartilage repair. PBSU-based mats created by electrospinning show promise as wound dressing materials because of their good mechanical properties, high surface area-to-volume ratio increased level...

We introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (GT), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems.  The modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-APA) by means of Escherichia coli ATCC11105 with penicill...

To reduce the frequency of administration and to improve the patient compliance, a once daily sustained release formulation of Atenolol is desirable. So sustained release Matrix Ta...

Bioadhesion can be defined as a phenomenon of interfacial molecular attractive forces amongst the surfaces of the biological substrate and the natural or synthetic polymers, which allows the polymer to adhere to the biological surface for an extended period of time. Bioadhesive polymeric systems have been used in the development of products for various biomedical applications and surgical glue....

Various scaling methods such as relative viscosity, Peclet and Reynolds scaling were used to find the best scaling law. Scaling and modeling of the flow curves of various model emulsions consist of Tragacanth Gum (TG) (0.5, 1 % wt), Oleic acid (5, 10% v/v) and WPI (2, 4 % wt) were investigated and the best models were selected. As these emulsions are non-Newtonian, they do not obey the usual...

The current study focuses on the synthesis of Cerium oxide (CeO2) nanocatalyst via Tragacanth Gum (TG) using wet impregnation method and its application for sustainable biodiesel production from a novel, non-edible Descurainia sophia (L.) Webb ex Prantl seed oil. D. oil has higher content (36 wt%) free fatty acid (FFA) value (0.6 mg KOH/g). Innovative analytical methods, such as X-ray diffracti...
