The present study involves preparation and evaluation of gastric-mucoadhesive microparticles with Metformin Hydrochloride as model drug for prolongation of gastric residence time. The microparticles were prepared by the emulsification solvent evaporation technique using polymers of Carbomer 934p (C) and Ethylcellulose (EC). The microparticles were prepared by emulsion solvent evaporation method...
Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections.Chitosan polyelectrolyte complex...

Backgrounds: Microparticles are one of drug delivery systems designed for sustained and controlled release of drugs for a long period of time. Clotrimazole is a broad-spectrum antifungal agent, which is generally used for treatment of Candida albicans and others fungal infections. Objectives: The present study aims to fabricate Clotrimazole microparticles using beeswax (lipophilic coating) an...
Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...

In this research, the capabilities of Henna and Henna with chitosan microparticles adsorbents were studied in order to remove the ion Cd (II). Response Surface Method (RSM) and Central Composite Design (CCD) were used to minimize the number of experiments (21 runs) for Henna and (26 runs) for the Henna with chitosan microparticles. The parameters were pH (2-9), initial solution concentratio...
Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...
Introduction: Apatite has been extensively studied on Earth because of its geological, geobiological, and materials importance [1], and it is one of the most common mineralogical reservoirs for phosphorus on Earth. Apatite is also present in each of the three types of SNC meteorites, implying the same may also be true for Mars. In addition to phosphorus, apatite commonly contains some combinati...
BACKGROUND Loosening of screws is a common problem in orthopedic and maxillofacial surgery. Modifying the implant surface to improve the mechanical strength of screws has been tried and reported. We developed screws coated with fibroblast growth factor-2 (FGF-2)-apatite composite layers. We then showed, in a percutaneous external fixation model, that this composite layer had the ability to hold...
