The competitive adsorption of collagen and bovine serum albumin (BSA) on surfaces with varied wettability was investigated with imaging ellipsometry, and ellipsometry. Silane modified silicon surfaces were used as substrates. The results showed that surface wettability had an important effect on protein competitive adsorption. With the decrease of surface wettability, the adsorption of collagen...

Cellular signaling involves a cascade of recognition events occurring in a complex environment with high concentrations of proteins, polysaccharides, and other macromolecules. The influence of macromolecular crowders on protein binding affinity through hard-core repulsion is well studied, and possible contributions of protein-crowder soft attraction have been implicated recently. Here we presen...

perfectionism, in fact, is an irrational belief individuals have about themselves and their surroundings. perfectionists believe that they and their surroundings must be complete and any attempt in life must be without error. the aim of the present study was to determine the relationship of positive and negative perfectionism with competitive state anxiety. 100 soccer players completed positive...

abstractinteraction of ni complex(salen= n, n´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (hewl) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. the protein binding affinity of ni complex was found to be (3.0×103m−1). the binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 m-1. i...
