Celecoxib, a selective cyclo-oxygenase – 2 inhibitor has been recommended orally for the treatment of arthritis and osteoarthritis. Long term oral administration of celecoxib produces serious gastrointestinal side effects. Therefore the aim of the present investigation was to assess the potential of nanosized emulsion formulations for transdermal delivery of celecoxib (CXB), to reduce the side ...
Highly active and stable MoS2/carbon hierarchical spheres with abundant active edge sites were fabricated by a simple micro-emulsion procedure where PVP was used as the carbon source, and carbon disulfide as the sulfur source and oil phase in micro-emulsion to control the morphology of MoS2. Hierarchical spheres of MoS2/carbon with a diameter of ca. 500 nm were obtained and characterized by sca...
The objective of this study is to evaluate the emulsifier role in the synthesis of Iron Polyaniline nanocomposite by in-situ oxidative polymerization of aniline and reduction of Iron ions into Fe nanoparticles. The polymerization of aniline was carried out in the presence of FeCl as oxidizing agent. During the reaction 3 aniline monomers undergo oxidation and form polyaniline (PANI) whereas the...
pigmented once more. Banifex contains the washings of an emulsion of micro-organisms which have been collected from as many birds as possible in different areas and over a period of a few years. The emulsion from which the washings are made contains 1000 million micro-organisms per c.cm. Two injections made intra-muscularly on consecutive days give the best results. Once the nerves become invol...
Tumor heterogeneity makes combination chemotherapy one of the preferred modes of treatment regimens. In this work, sequential exposure of two anticancer agents, paclitaxel (Tx) followed by topotecan (TPT), was shown to have a synergistic effect on non-small cell lung cancer (NSCLC) cell line, NCI-H460. In order to improve patient compliance, the aforementioned concept was translated into a drug...

Ever since C.R.Berry found quantum size effect on nanometer-sized AgX grain and made studies on its anomalous absorption behaviour, much effort has been made on different aspects of nanometer-sized grain emulsion. H.Thiry, M.Iwasaki and his coworkers prepared nanometer-sized AgBr or AgBrI grain emulsion below 30nm scale and made some attempts on spectral sensitization; Investigated the mixture ...
Water-in-oil emulsions are commonly used to provide persistent release of antigens necessary for sustained stimulation of the immune system. Optimal response of an animal's immune system is dependent upon repeated, maintained exposure to the antigen. The sustained release of antigen, which delays catab-olism, is thought to be one of the major methods by which adjuvants enhance the immune respon...
As part of a wider study into high internal phase emulsions, we have prepared and studied by SANS and USANS the structure of an unstable emulsion consisting of 90% by volume saturated ammonium nitrate dispersed as micron-scale droplets in hexadecane, stabilised by the surfactant Pluronic L92. Similar emulsions produced using polyisobutylene-based surfactants, reported earlier, are highly stabil...
