Changes in the cell surface properties of amoebae of Dictyostelium discoideum during growth in different culture conditions have been studied by aqueous two-phase partitioning on a thin-layer countercurrent distribution apparatus. Changes in cell surface properties were not dependent on the source of nutrients but only on cell density. There was a progressive increase in cell surface hydrophobi...

the aberrant assembly of proteins into fibrillar aggregates is accused to be the primary cause of pathogenesis of neurodegenerative diseases. but the structural determinants of protein fibrils that are responsible for cell dysfunction are not yet clear. in the current study, cell culture, spectroscopic techniques as well as theoretical and structural investigations were used to determine the ab...

This article presents the surface modification of iron Fe (110) surfaces with Poly-L-Lysine (PLL) aim preparing carbonyl bone implants which are less corrosive and more compatible fibroblast cells. The cytocompatibility modified commercially available α-PLL electrodeposited ε-PLL was compared by combination DFT computational simulations experimental electrochemical cell adhesion studies to obta...

Zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (TMVS) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. Then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...
