The objective of the current investigation is to reduce dosing frequency and improve patient compliance by designing and systematically evaluating sustained release microballoons of Propranolol hydrochloride. An antihypertensive drug, Propranolol hydrochloride, is delivered through the microparticulate system using ethyl cellulose as the controlled release polymer. Microballoons were developed ...

Chromatographic separation of native DNA from DNA containing single-stranded regions has been used to determine the relative concentrations of structural intermediates generated during chemically induced DNA repair. Single doses of each of ten compounds were administered to rats. After periods ranging from 90 min to 13 days, hepatic DNA was isolated and analyzed by stepwise elution from benzoyl...

The present study involves design and characterization of floating microspheres with Nateglinide as model drug for prolongation of gastric residence time. Nateglinide Floating Microspheres were prepared by w/o/o emulsification solvent diffusion technique using rate controlling polymers ethyl cellulose and hydroxy propyl methyl cellulose. The shape and surface morphology of prepared microspheres...

Non-naturally branched polysaccharides were prepared homogeneously by reaction of cellulose in N,N-dimethyl acetamide/LiCl and the ionic liquid 1-N-butyl-3-methylimidazolium chloride with 2,3,4,6-tetraacetyl-1-bromo-α-D-glucopyranoside in the presence of triethylamine as base. Degrees of substitution up to 0.58 were realized. The samples were soluble in dimethyl sulphoxide and water. NMR spectr...

In this study, novel photocatalyst monolith materials were successfully fabricated by a non-solvent induced phase separation (NIPS) technique. By adding a certain amount of ethyl acetate (as non-solvent) into a cellulose/LiCl/N,N-dimethylacetamide (DMAc) solution, and successively adding titanium dioxide (TiO₂) nanoparticles (NPs), cellulose/TiO₂ composite monoliths with hierarchically porous s...

Rice is a model plant species for the study of cellulose biosynthesis. We isolated a mutant, S1-24, from ethyl methanesulfonate (EMS)-treated plants of the japonica rice cultivar, Nipponbare. The mutant exhibited brittle culms and other pleiotropic phenotypes such as dwarfism and partial sterility. The brittle culms resulted from reduced mechanical strength due to a defect in thickening of the ...

The purpose of present investigation was to develop and optimize bucco mucoadhesive bilayered tablets of Propranolol hydrochloride (PrHCL) using the bioadhesive polymers hydroxyl propyl methyl cellulose (HPMC K4M), xanthan gum (XG) and acrypol 934P (AL-P) individually and in combination along with ethyl cellulose (EC) as an impermeable backing layer. The 3 full factorial design was employed by ...
