Bone scaffolds play an important role in promoting the healing of large bone defects. However, type scaffold material, drug loaded into scaffold, and method preparation have a significant impact on scaffold's properties. In this study, we developed composite comprising sodium alginate (SA), chitosan (CS), hydroxyapatite (HA). The stent carries vascular endothelial growth factor (VEGF), wrapped ...

Mechanical characterization of Portland cement with hollow glass microspheres two different crushing strengths, 500 (FM) and 10,000 psi (3 M), was carried out to determine both quasi-static dynamic responses the cementitious composites. In tests, time resolved high speed camera photos deforming specimens revealed stress levels at which incipient damage occurred. The split-Hopkinson pressure bar...

nano-hydroxyapatite/gelatin (nha/ge) microspheres are currently used in bone tissue engineering as bone filler. in this  study, the effect of fabrication process parameters on the particle size of nano-hydroxyapatite/gelatinmicrospheres was investigated. the nha/ge microspheres were fabricated using water in oil emulsion. in order to design an experimental design, a surface response model with ...

       The cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. The stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into n...

The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. Propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934P as mucoadhesive polymer and ethyl cellulose as carrier ...

Thermostable heat-insulating composite materials based on solid magnesium phosphate and calcium binders, fly-ash glass hollow microspheres have been developed proposed. Thermal phase transformations studied as well strength characteristics of the initial composites products their thermal treatment up to 1000 °C determined. It is shown that prepared are thermally stable in temperature range 20 –...

      The objective of the present study was to develop floating microspheres of cefpodoxime proxetil in order to achieve an extended retention in the upper GIT, which may result in enhanced absorption and thereby improved bioavailability. The microspheres were prepared by non-aqueous solvent evaporation method using polymers such as hydroxyl propyl methyl cellulose (HPMC K 15 M), ethyl cellulo...

A simple and versatile method for preparation of new crystalline vanadium oxide hydrate semi-microspheres is developed via a simple hydrothermal route, which are tested as a novel high-energy anode materials for sodium-ion batteries. The enhancement of electrochemical performance for the vanadium oxide hydrate electrode is offered by addition of graphene. The graphene-based vanadium oxide hydra...
