Toxicity of nanoparticles (NPs) is often correlated with the physicochemical characteristics of the materials. However, some discrepancies are noted in in-vitro studies on quantum dots (QDs) with similar physicochemical properties. This is partly related to variations in cell type. In this study, we show that epithelial (BEAS-2B), fibroblast (HFF-1), and lymphoblastoid (TK6) cells show differen...

The catalytic performance of Fe-Cr/ZrO2 catalysts, prepared by two different methodsscoprecipitation and coprecipitation-impregnation were examined in oxidative dehydrogenation of ethane to ethylene using CO2 as an oxidant. Thermogravimetric analysis and physicochemical characterization such as XPS, XRD, and BET were performed to explore the correlation of catalytic performance with physicochem...

Seabuckthorn (SBT; Hippophae rhamnoides L.) is a thorny bush found growing wild in high altitude cold deserts of India. Present study involved pharmacognostical (Botanical and physicochemical) characterization and phytochemical investigation of SBT leaves. Botanical characterization revealed the presence of large amount of stellate trichomes. Among physicochemical parameters, total ash was foun...

The physicochemical characterization of the textile industry effluent collected from Oswal Textile Industries, Ludhiana (Punjab.) India has been carried out and the results showed that the temperature (40°C), pH (8.00), Biological Oxygen Demand (260 mgl –1 ), Chemical Oxygen Demand (790 mgl –1 ), Total Suspended Solids (2000 mgl –1 ), Total Dissolved Solids (7000 mgl –1 and colour over the pres...

The data presented in this article are related to the research article entitled "Biphasic calcium phosphates bioceramics (HA/TCP): Concept, physicochemical properties and the impact of standardization of study protocols in biomaterials research" [1]. This article provides in depth study of BCP bone substitutes as valuable option in the field of tissue engineering. However, there are discrepanci...

The present study was undertaken to develop a suitable transdermal matrix patch of ketorolac tromethamine with different proportions of polyvinyl pyrrolidone (PVP) and ethyl cellulose (EC) using a D-optimal mixture design. The prepared transdermal patches were subjected to different physicochemical evaluation. The surface topography of the patches was examined by scanning electron microscopy (S...

The physiochemical characteristics of the follicle-stimulating hormone (FSH) from whole sheep pituitary glands have been studied. The hormone behaves as a single protein in electrophoresis, diffusion, and ultracentrifugation. It has an isoelectric point at pH 4.5 and a molecular weight of 67,000 and contains 1.23 per cent hexose and 1.51 per cent hexosamine. The amino acid composition has also ...

Protamine-oligonucleotide nanoparticles represent effective colloidal drug carriers for antisense phosphorothioate oligonucleotides (PTO). This study describes improvements in particle preparation and the physicochemical properties of the complexes prepared. The influence of component concentrations, length of the PTO chain and the PTO/protamine weight ratio on particle formation and size, shap...
