BACKGROUND Bovine serum albumin nanoparticles loaded with isoniazid and rifampicin (INH-RFP-BSA-NPs) were prepared and their release characteristics were studied in vitro. MATERIAL AND METHODS The INH-RFP-BSA-NPs were prepared by a modified self-emulsion solvent diffusion method, with albumin and polylactic acid used as carriers and to form the nanoparticles structure. Transmission electron mic...

Objective: The envisaged research work aims to develop a nanosponge loaded gel for the treatment of Streptococcal gangrene. Methods: In present study, permeability is enhanced by targeted drug release formulation topical clindamycin phosphate nanosponges were prepared emulsion solvent diffusion method using ethyl cellulose as retardant polymer and PVA surfactant or emulsifier. Nanosponges chang...

Microautoradiography (MAR) is a conventional imaging method based on the daguerreotype. The technique is used to visualize the distribution of radionuclide-labeled compounds within a tissue section. However, application of the classical MAR method to plant tissue sections is associated with several difficulties. In this study, we report an MAR method applicable to fresh-frozen plant sections. O...

Objective: The objective of the present study was to compare release effect Luliconazole from different polymeric (Hydrophilic and Hydrophobic) microsponges prepared using varying concentrations. best microsponge selected incorporated into gel (Natural synthetic) drug is determined compared with marketed formulation.
 Methods: Polymers such as EC, HPMC, Eudragit RSPO PVA emulsifier, solven...

Catalase-loaded solid lipid nanoparticles (SLNs) were prepared by the double emulsion method (w/o/w) and solvent evaporation techniques, using acetone/methylene chloride (1:1) as an organic solvent, lecithin and triglyceride as oil phase and Poloxmer 188 as a surfactant. The optimized SLN was prepared by lecithin: triglyceride ratio (5%), 20-second + 30-second sonication, and 2% Poloxmer 188. T...

An autoradiographic method has been developed by which the presence of soluble intracellular materials can be determined for individual cells (1). Our immediate need for the method was to measure the uptake of H3-thymidine into soluble pools during various stages of the cell life cycle, but it should be applicable to the assay of various soluble radioactive materials in a variety of cell types ...

Using the emulsion method, we measured the homogeneous nucleation temperature depression, DeltaT(f,hom), and equilibrium melting points depression, DeltaT(m), of various aqueous solutions and then calculated lambda for each solute using the linear relationship DeltaT(f,hom) = lambdaDeltaT(m). We defined lambda as the solute-specific supercooling capacity and examined its correlation with some k...

An emulsion solvent evaporation method was employed to prepare microspheres of ropinirole hydrochloride, a highly water soluble drug, by using ethylcellulose and PEG with the help of 32 full factorial design. The microspheres were made by incorporating the drug in a polar organic solvent, which was emulsified using liquid paraffin as an external oil phase. Effects of various process parameters ...

Email: [email protected] ABSTRACT Purpose. To generate biodegradable poly(lactic-co-glycolic acid) (PLGA) microparticles without using volatile organic solvent for a sustained protein release. Methods. The formulation of microparticles is based on the formation of an emulsion of polymer solution in CO2 medium. Polymer solution was prepared in injectable non-volatile solvent such a...

A novel method for the fabrication of monodisperse mesoporous silica particles is suggested. It is based on the formation of well-defined equally sized emulsion droplets using a microfluidic approach. The droplets contain the silica precursor/surfactant solution and are suspended in hexadecane as the continuous oil phase. The solvent is then expelled from the droplets, leading to concentration ...
