Objective(s): Three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. In the present study, poly(vinyl pyrrolidone) (PVP)/ poly(vinyl alcohol)(PVA) hybrid nanofibrous scaffold was synthesized by electrospinning. Materials and Methods: The effect of adding nano h...

Arginine (Arg) is a commonly used additive to prevent protein aggregation and inactivation in denaturing solutions. This paper presents new findings on the synergistic effect on the prevention of heat-induced aggregation of lysozyme using Arg in combination with polyethylene glycol (PEG). The synergistic enhancement was observed in the presence of Arg with amphiphilic polymers, such as PEG6000,...

Poly(vinyl alcohol) and polyethylene polymer systems were built in order to study their transport properties (diffusion). First a verification of the AMBER force field was conducted for a poly(vinyl alcohol) system built from a chain with 145 repeating units. NPT-molecular dynamics simulations at temperatures between 400 and 527 K were performed. The results of the simulations were compared wit...
