The toxic effect of Al2O3, SiО2 and ZrО2 nanoparticles on red blood cells of Wistar rats was studied in vitro using the atomic force microscopy and the fluorescence analysis. Transformation of discocytes into echinocytes and spherocytes caused by the metal oxide nanoparticles was revealed. It was shown that only extremely high concentration of the nanoparticles (2mg/ml) allows correct estimating of...
Cellulose acetate (CA) fibers loaded with naproxen ester prodrug, naproxen methyl ester, were prepared through a wet-spinning technique by using N, N-dimethylacetamide (DMAc) as a solvent. The chemical and morphological characterizations of the medicated fibers were investigated by means of scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), as well as the studies...
The crystalline phases and degree of crystallinity in plasma sprayed calcium phosphate coatings on Ti substrates are crucial factors that influence the biological interactions of the materials in vivo. In this study, plasma sprayed hydroxyapatite (HA) coatings underwent post-spray treatment by the spark plasma sintering (SPS) technique at 500 o C, 600 o C, and 700 o C for duration...
