there are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. however, there is little information to prove such effect on flat breads. the main aim of this study was to improve the quality of barbari dough and bread (iranian flat bread) in terms of texture, taste and general acceptability of fres...

The use of uncoated fused silica capillary columns and hydroxypropylmethyl cellulose (HPMC) in capillary electrophoresis (CE) to separate DNA ladders and plasmids is described. In these studies HPMC is used as a sieving matrix to separate DNA. Many previous studies have focused on using coated and gel-filled capillaries to *Correspondence: F. A.

The amalgamation of polymer and pharmaceutical sciences led to the introduction of polymer in the design and development of drug delivery systems. Polymeric delivery systems are mainly intended to achieve controlled or sustained drug delivery. Polysaccharides fabricated into hydrophilic matrices remain popular biomaterials for controlled-release dosage forms and the most abundant naturally occu...

in order to formulate an efficient and durable mucoadhesive drug delivery system, careful consideration of formulation-related parameters is critical. this study was conducted to investigate the effect of the presence of various types and concentrations of surfactants within or outside carbopol 934 (c934) as well as hydroxypropylmethyl cellulose (hpmc) solid compacts, on their duration of mucoa...

The objectives of this study were to develop a novel solid dutasteride formulation with improved physicochemical properties and oral bioavailability, and to examine the correlation between its in vitro dissolution and in vivo pharmacokinetic parameters. Hydroxypropyl-β-cyclodextrin (HP-β-CD) nanostructures with or without hydrophilic additives were manufactured using the supercritical antisolve...

Some known mechanisms proposed for the reduction of blood cholesterol by dietary fibre are: binding with bile salts in the duodenum and prevention of lipid absorption, which can be partially related with the bile salt binding. In order to gain new insights into the mechanisms of the binding of dietary fibre to bile salts, the goal of this work is to study the main interactions between cellulose...

In this work we present an analysis of the thermal behavior of hydroxypropylmethyl cellulose aqueous solutions, from room temperature to higher temperatures, above gelation. We focus on significant aspects, essentially overlooked in previous work, such as the correlation between polymer hydrophobicity and rheological behavior, and the shear effect on thermal gelation. Micropolarity and aggregat...
