The aim of the present study is to evaluate the potential differentiation ability of gingiva originated human mesenchymal stem cell in the presence of tacrolimus. Tacrolimus-loaded poly(lactic-co-glycolic acid) microspheres were prepared using electrospraying technique. In vitro release study of tacrolimus-loaded poly(lactic-co-glycolic acid) microspheres was performed in phosphate-buffered sal...

We investigate the phenomenon of quantum interference in spontaneous emission for a three-level V-type emitter placed between two bismuth-chalcogenide (Bi2Te3, Bi2Se3) microspheres. In particular, we find that degree can become as high 0.994, value which is attributed to strong dependence rate on orientation an atomic dipole relative surfaces microspheres, at excitation frequencies phonon-polar...

To prepare the sustained release vitamin C carriers, vitamin C was successfully encapsulated in tripolyphosphate (TPP) cross-linked chitosan (TPP-chitosan) microspheres by the spray-drying method at different manufacturing conditions. Manufacturing parameters (inlet temperature, liquid flow rate, chitosan concentration and volume of 1% w/v TPP solution) had a significant influence on the charac...

Functionalization of a porous orthopedic implant with dexamethasone, a widely used anti-inflammatory drug, encapsulated within a biodegradable polymer for controlled release could help reduce or eliminate the inflammation response by the local tissue. In this research, we investigated the possibility of using supercritical carbon dioxide (CO₂) for attaching dexamethasone-loaded PLGA (polylactic...

Feeding and food choice are crucial to the survival of an animal. The nematode Caenorhabditis elegans feeds on various microorganisms in nature, and is usually fed Escherichia coli in the laboratory. To elucidate the mechanisms of food/non-food discrimination in C. elegans, we examined the accumulation of various fluorescent polystyrene microspheres in the absence and presence of bacterial food...

This study concerns the preparation, physical, and in vitro characterization of two different types of hydroxyapatite (HA) microspheres, which are intended to be used as drug-delivery systems and bone-regeneration matrices. Hydroxyapatite nanoparticles (HA-1 and HA-2) were prepared using the chemical precipitation synthesis with H(3)PO(4), Ca(OH)(2), and a surfactant, SDS (sodium dodecyl sulfat...

Thermoresponsive P(NIPAM-AA)/Fe₃O₄/SiO₂ microspheres with surface holes serving as carriers were prepared using p-Fe₃O₄/SiO₂ microspheres with a thermoresponsive copolymer. The p-Fe₃O₄/SiO₂ microspheres was obtained using a modified Pickering method and chemical etching. The surface pore size of p-Fe₃O₄/SiO₂ microspheres was in the range of 18.3 nm~37.2 nm and the cavity size was approximately ...

Poly(3-hydroxybutyrate), P(3HB), produced from Bacillus cereus SPV using a simple glucose feeding strategy was used to fabricate P(3HB) microspheres using a solid-in-oil-water (s/o/w) technique. For this study, several parameters such as polymer concentration, surfactant and stirring rates were varied in order to determine their effect on microsphere characteristics. The average size of the mic...

The purpose of the present study was to compare the in vitro release and to find out whether the bioavailability of a 75 mg indomethacin capsule (Microcid SR) was equivalent to optimized formulation (indomethacin-loaded cetyl alcohol microspheres). Indomethacin-loaded cetyl alcohol microspheres were prepared by meltable emulsified cooling-induced technique. Surface morphology of microspheres ha...
