In this study, we fabricated PCL-nanoparticles by encapsulating dual drugs as amphotericin B and doxorubicin via double-emulsion solvent evaporation method also incorporated with ligand-lectin for targeting the infested macrophage cells and prove importance against VL. Different independent processing parameters were assessed systematically to enhance the incorporation of the dual agents with d...

Poly(vinyl chloride) resins are produced by four basic processes: suspension, emulsion, bulk and solution polymerization. PVC suspensions resins are usually relatively dust-free and granular with varying degrees of particle porosity. PVC emulsion resins are small particle powders containing very little free monomer. Bulk PVC resins are similar to suspension PVC resins, though the particles tend...

Superparamagnetic iron oxide nanoparticles (SPIONs) exhibit unique magnetic properties that make them highly efficacious as MR imaging contrast agents and laboratory diagnostic tools. The complexity of SPION magnetic behavior and the multiple parameters affecting this behavior complicate attempts at fabricating particles suited for a particular purpose. A mathematical model of SPION magnetic pr...

introduction: particle size and distribution can influence the properties of materials. this study analyzed and compared the particle size of root mta, calcium hydroxide (ch), and a new endodontic cement called calcium enriched material (cem). materials and methods: the particle size of each material was analyzed three times using 0.05 mg of test material with a particle size analyzer. the part...

glycerol mono-oleate (gmo) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of cofe2o4 nano-particles by surfactant-assisted microwave method. fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and...

ApoA-I is a uniquely flexible lipid-scavenging protein capable of incorporating phospholipids into stable particles. Here we report molecular dynamics simulations on a series of progressively smaller discoidal high density lipoprotein particles produced by incremental removal of palmitoyloleoylphosphatidylcholine via four different pathways. The starting model contained 160 palmitoyloleoylphosp...

INTRODUCTION The setting times of commercial mineral trioxide aggregate (MTA) and Portland cements vary. It was hypothesized that much of this variation was caused by differences in particle size distribution. METHODS Two gram samples from 11 MTA-type cements were analyzed by laser diffraction to determine their particle size distributions characterized by their percentile equivalent diameter...

the conversion process of heavy hydrocarbons to the valuable products such as gasoline is an important operation in the oil refineries.one important process is the “fluidized catalytic cracking” (fcc).feed injection in fcc process has an important role in the selectivity and properties of the products.performance of the feed injection system is dependent on the atomizers.the size and contributi...
