background: the development of injectable sustained-release products are of great interest to veterinary pharmaceuticals and animal health business. recently, great attention has been paid to in situ gel-forming chitosan/beta-glycerophosphate (chitosan/β-gp) solutions due to their good biodegradability and thermosensitivity. objectives: the general aim of this study was to prepare a novel in si...

BACKGROUND AND THE PURPOSE OF THE STUDY The poor bioavailability and therapeutic response exhibited by the conventional ophthalmic solutions due to precorneal elimination of the drug may be overcome by the use of mucoadhesive in situ gel forming systems that are instilled as drops into the eye and undergo a sol-gel transition in the cul-de-sac and have good mucoadhesion with ocular mucus layers...

The chemical bonding of particulate photocatalysts to supporting material surfaces is of great importance in engineering more efficient and practical photocatalytic structures. However, the influence of such chemical bonding on the optical and surface properties of the photocatalyst and thus its photocatalytic activity/reaction selectivity behavior has not been systematically studied. In this i...

5-Hydroxymethylfurfural (HMF) synthesis from glucose over in-situ phosphated titania catalysts is presented. Phosphates were incorporated into framework forming a titanium phosphate surface layer, where the coordinatively unsaturated tetrahedral TiO 4 units act as water-tolerant Lewis acid site (LAS) and adjacent protonated Brønsted (BAS), together Lewis-Brønsted pairs at molecular-level proxim...

PURPOSE To develop an in situ gel system comprising liposome-containing paclitaxel (PTX) dispersed within the thermoreversible gel (Pluronic® F127 gel) for controlled release and improved antitumor drug efficiency. METHODS The dialysis membrane and membrane-less diffusion method were used to investigate the in vitro drug release behavior. Differential scanning calorimetry (DSC) thermal analys...

Soluplus (Sol) is an amphiphilic graft copolymer capable of forming self-assembled micelles and L-ascorbyl 2,6-dipalmitate (ASC-DP) aggregates spontaneously to form micelles. Micelles are used as drug carriers can nanoparticulate drugs that poorly soluble in water, such minoxidil. The study aimed prepare minoxidil-encapsulated nanoparticles using Sol/ASC-DP evaluate their potential for targeted...

The oral delivery of drugs having narrow absorption window in the gastro-intestinal tract is limited by poor bioavailability with conventional dosage forms due to incomplete drug release and short residence time at the time of absorption. To provide controlled delivery of drugs novel drug delivery systems have been developed. Different systems have been developed to increase the gastric residen...
