in this research, after carrying out chemical tests measuring the moisture, protein and ash contents on rice flour according to standard methods, gluten- free breads were prepared from rice flour combined with 0.5% carboxy methyl cellulose (cmc) and 1% -κcarrageenan gum. a sample lacking gum was also produced as control. rice breads (with gum and without gum) were then produced by semi-industri...

novel citric acid modified starch-carboxy methyl cellulose (cmc) -montmorillonite (mmt) bionanocomposite films were prepared by casting method and the effect of mmt on the structural and physical properties of the starch-cmc biocomposites was studied. x-ray diffraction test showed thatstrong polar interactions between the hydroxyl groups present in the starch and cmc chains and in the silicate ...

The present investigation is concerned about the development of floating bioadhesive drug delivery system of venlafaxine hydrochloride which after oral administration exhibits a unique combination of floating and bioadhesion to prolong gastric residence time and increase drug bioavailability within the stomach. The floating bioadhesive tablets were prepared by the wet granulation method using d...

PURPOSE To evaluate the efficacy of transepithelial corneal collagen crosslinking (TE-CXL) in patients with progressive keratoconus. PATIENTS AND METHODS This is a prospective interventional consecutive study carried out on 30 eyes of 18 patients with progressive keratoconus who underwent TE-CLX using both ParaCel™ (riboflavin 0.25%, hydroxy propyl methyl cellulose, NaCl, ethylenediaminetetra...

Synthesis of 2-(2-hydroxy-3-amino)propyl derivatives of 4-alkoxy-6-methyl-1H-pyrrolo[3,4-c]pyridine-1,3(2H)-diones (24-35) is described. The chlorides used in the above synthesis exist mainly in the cyclic forms (18, 20-23). Only chloride with benzhydryl substituent at the nitrogen atom of piperazine has the chain structure (19). Among the studied imides the most active analgesics in the "writh...

Synthesis of 1-[2-hydroxy-3-(4-o,m,p-halogenophenyl)- and 3-(4-m-chlorophenyl)-1-piperazinyl]propyl derivatives of amides of 7-methyl-3-phenyl-2,4-dioxo-1,2,3,4-tetrahydropyrido[2,3-d]pyrimidine-5-carboxylic acid (18, 20-23, 25, 27-30 and 19, 24, 26) is described. All substances were active as analgesic agents in "writhing syndrome" test and except of 18 and 23 they acted stronger than acetylsa...

The eye presents unique opportunities and challenges when it comes to the delivery of Pharmaceuticals. While absorption by this route is bungling, there are few side effects with conventional ocular dosage forms like eye drops and eye suspensions. Several polymeric systems have been used to fabricate ocular inserts for better ocular bioavailability and retention of drug for which gelling system...

In vivo EPR oximetry is a powerful minimally invasive method that allows the measurement of oxygen in tissues through the use of a paramagnetic probe. In the present study, we investigated new strategies for preparing biocompatible inks containing carbon black particles (Printex U), which could be used as oxygen sensors. The carbon black particles were dispersed in solutions of biocompatible po...

Second-degree burns have the highest prevalence and often occur in household environment. The healing process can be accelerated by traditional medicine. One of many plants known to wound-healing abilities is Binahong plant (Anredera cordifolia (Ten.) Steenis). gel preparation chosen because benefits it provide. gelling agents used were Hydroxypropyl Methyl Cellulose Hydroxyethyl Cellulose. com...

BACKGROUND Derivatized celluloses, such as methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC), are of pharmaceutical importance and extensively employed in tablet matrices. Each batch of derivatized cellulose is thoroughly characterized before utilized in tablet formulations as batch-to-batch differences can affect drug release. The substitution pattern of the derivatized cellulose p...
