Chitosan has prompted the continuous movement for the development of safe and effective drug delivery systems because of its unique physicochemical and biological characteristics. The primary hydroxyl and amine groups located on the backbone of chitosan allow for chemical modification to control its physical properties. When the hydrophobic moiety is(More)
The objective of the study was to formulate and to investigate the combined influence of 3 independent variables in the optimization of Polymeric lipid hybrid nanoparticles (PLHNs) (Lipomer) containing hydrophobic antifungal drug Itraconazole and to improve intestinal permeability. The Polymeric lipid hybrid nanoparticle formulation was prepared by the(More)
Fifty halotolerant bacterial strains were isolated from the alkaline saline soil from the Ajod village of Vadodara district of Gujarat. All strains grew well in media supplemented with 5 % NaCl, but two strains (BR5 and BN7) could grow even at 18 % NaCl concentration. These two strains were characterized for their plant growth promoting characteristics.(More)
Collar rot disease due to A. niger in ground nut plants causes a great loss in yield. Using a PGPR isolated from the field of same plants, we aimed to study effect on control of this disease as well as to study effect on seed germination and development of Induced systemic resistance in germinated seedlings. Different strain of bacteria were isolated and(More)
The objective of the present study was to formulate and optimize exemestane (EXM) encapsulated vitamin E-TPGS-poly-ɛ-caprolactone based polymeric nanoparticles (TPGS-PCLNPs) for enhancing its anticancer efficacy. The 23 factorial design was employed to investigate the combined influence of formulation and process variables on properties of TPGS-PCLNPs,(More)
OBJECTIVE The present research work was intended to develop and optimize sustained release of biodegradable chitosan nanoparticles (CSNPs) as delivery vehicle for sodium cromoglicate (SCG) using the circumscribed Box-Behnken experimental design (BBD) and evaluate its potential for oral permeability enhancement. METHODS The 3-factor, 3-level BBD was(More)
CONTEXT Curcumin (CUR), can inhibit proliferation and induce apoptosis of tumor cells, its extreme insolubility and limited bioavailability restricted its clinical application. OBJECTIVE An innovative polymeric nanoparticle of CUR has been developed to enhance the bioavailability and anti-cancer efficacy of CUR, in vitro and in vivo. MATERIALS AND(More)
OBJECTIVE The study aims at formulation and optimization of macrophage-targeted curcumin-loaded mannosylated chitosan nanoparticles (Cur-MCNPs) of curcumin (CUR) to improve its therapeutic potential in the treatment of visceral leishmaniasis (VL). METHODS Response surface methodology (RSM) using central composite design was employed to study the effect of(More)
Atorvastatin calcium (ATR), a second generation statin drug, was encapsulated in eudragit RSPO-based polymeric nanoparticles. The effect of independent variables (polymer content, stabilizer concentration, volume of chloroform and homogenization speed) on response variables (mean diameter particle size and entrapment efficiency) were investigated by(More)
Metronidazole (MZ) and levofloxacin (LF) are widely employed for treatment of periodontitis, but high oral dose and resistance development after long-term oral administration limit their use. The aim of this study was to alleviate shortcomings in the treatment of periodontitis by fabrication of intrapocket, biodegradable films of chitosan (CS) loaded with(More)
