Matrix metalloproteases are key regulatory molecules in the breakdown of extracellular matrix and in inflammatory processes. Matrix metalloproteinase-1 (MMP-1) can significantly enhance muscle regeneration by promoting the formation of myofibers and degenerating the fibrous tissue. Herein, we prepared novel MMP-1-loaded poly(lactide-co-glycolide-co-caprolactone) (PLGA-PCL) nanoparticles (NPs) c...

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Simultaneous removal of $${\text{Cr}}^{3+}$$ and acidic dye from model tannery wastewater was investigated using local nano-clay modified by 3-chloro-2-hydroxypropyltrimethylammonium chloride surfactant. X-ray fluorescence, Fourier-transform infrared spectroscopy, diffraction, scanning electron microscopy, carbon, hydrogen, nitrogen sulfur analysis, Brunauer–Emmet–Teller analysis pH zero-point ...

This article presents the results of a simulation model designed to reduce patient waiting time in the emergency department of a hospital in the United Arab Emirates. The process-oriented simulation model shows how the resources in the hospital are inter-related. The model depicts the hospital operating system and its performance and management issues with regards to allocation of human and mat...

The possibility of gas explosion accidents always exists at offshore facilities of the oil and gas industry. In the design of those structures, the structural safety assessment against explosion loads is necessary to prevent loss of lives or catastrophic failure of structures. One of the essential parts in the structural assessment is to determine design explosion loads. Nowadays, the explosion...

An experimental study has been conducted on the adsorption of Direct red-28 dye using activated carbon prepared from Punica granatum (Pomegranate rind) by chemical activation with sulphuric acid. BET surface area of the activated carbon was determined as 1075.6 m.g and SEM observations showed the amorphous nature of the carbon. Adsorption kinetics, equilibrium and thermodynamics were investigat...

Homogenate extraction method was applied to fast extraction of polysaccharides from loquat leaves. Factors which affected extraction yield were investigated and optimized by response surface methodology (RSM). Results showed that optimum technological conditions were as follows: ratio of liquid to material, 25 ml: 1g; extraction time, 100 s; and pH of extracting solvent, 11. Under optimum condi...

Abstract Background This work studied the performance of UV/PS/TiO 2 NPs and UV/PI/TiO as hybrid advanced oxidation processes for degradation paraquat in aqueous solution, because this very toxic herbicide is used third most widely. Results The effects several factors such UV irradiation, initial oxidant concentration, TiO nanoparticles dosage, pH on efficiency were investigated. process optimi...
