prolonged residence of drug formulation in the nasal cavity is important for the enhancing intranasal drug delivery. the objective of the present study was to develop a mucoadhesive in-situ gelling nasal insert which would enable the reduced nasal mucociliary clearance in order to improve the bioavailability of metoclopramide hydrochloride. metoclopramide hydrochloride is a potent antiemetic an...

in this study, physicochemical and organoleptical properties of muffin cake prepared by substitution of egg white with different levels of whey protein concentrate (wpc) and different levels of guar and xanthan gums in the furmolation were evaluated.wpc at three levels ;25 , 50 and 75 % , guar gum at two levels ; 0.1 and 0.3 % , and xanthan gum at two levels ; 0.1 and 0.15 % , were considered a...

The effects of different hydrocolloids on the gelatinisation behaviour of hard wheat flour were investigated. Influence of guar, xanthan, Arabic, carboxy methyl cellulose (CMC) and tragacanth gums on wheat flour was studied using micro viscoamylograph. It was found that all hydrocolloids except tragacanth greatly modified the gelatinisation properties of wheat flour. Guar and xanthan significan...

The interaction of dextrin and guar gum with pyrite has been investigated through adsorption, flotation, and electrokinetic measurements. The adsorption densities of the polysaccharides onto pyrite reveal a region of higher adsorption density in the pH range 7.5-11, with a maximum around pH 10 for both polymers. The isotherms exhibit Langmuirian behavior. The adsorption density of guar gum onto...

We present a method for providing hard real time guar antees for tra c through an Asynchronous T ransfer Mode A TM network Guarante eddelivery also im plies that we have to guarantee that no cells are lost due to over full bu ers in the network By using priority queues in the output bu ers we allow urgent messages short end to end delays while still guar anteing end to end delays for low priori...

A novel membrane based on silicon dioxide (SiO₂) and hydroxypropyl guar gum (HPG) as binder is presented and tested as a separator for lithium-ion batteries. The separator is made with renewable and low cost materials and an environmentally friendly manufacturing processing using only water as solvent. The separator offers superior wettability and high electrolyte uptake due to the optimized po...

Diclofenac sodium is an Non-steroidal anti-inflammatory drugs, having an elimination half-life of 1-2 hrs. The objective of the study is to prepare Diclofenac sodium Microbeaads using Natural Polymers in different concentrations. For this purpose calcium ions were used as cross linking agents in formulation of alginate-guar gumpectin, alginate-guar gum-lecithin and alginate-pectin-lecithin Micr...

Mucilage of malva nut fruit has been used as traditional medicine in Thailand. Our laboratory has succeeded in extracting malva nut gum (MNG) from malva nut seeds by using alkaline-extraction method. The extract had higher gelling properties compared to water-extracted MNG. This research was aimed to investigate the effect of MNG on the retardation of glucose diffusion in in vitro dialysis proc...
