in this work quantitative structure activity relationship (qsar) methodology was applied for modeling and prediction of cellular response to polymers that have been designed for tissue engineering. after calculation and screening of molecular descriptors, linear and nonlinear models were developed by using multiple linear regressions (mlr) and artificial neural network (ann) methods. the root m...

This paper focuses on the significant properties of hydrogels prepared with polymeric biomaterials: solely biopolymers (gelatin (G) and sodium alginate (SA) as base polymer) or in combination with synthetic and bio polymers (polyvinylpyrrolidone (PVP) and carboxymethylcellulose (CMC)) for biomedical application. Four kinds of hydrogels: G/SA, G/SA/SB (without and with seabuckthron oil (SB)) and...

Pre-clinical biomaterial development and testing have traditionally relied on 2D in vitro, or complex in vivo assays. It is essential for the cell environment to match the natural tissue in terms of matrix density, architecture, components (including stress/strains) for tissue models to behave in a natural manner. The aim of this project is to improve existing in vitro models for the biomateria...

New medical products, materials and surgical procedures keep improving current health-care practices. Many of these innovations involve polymeric devices that must meet certain clinical and cost requirements. Chief among these pressures is the need for biocompatibility between the physiological environment and the biomaterial surface. Plasma surface modification can improve biocompatibility and...

An off-the-shelf vascular graft biomaterial for vascular bypass surgeries is an unmet clinical need. The vascular biomaterial must support cell growth, be non-thrombogenic, minimize intimal hyperplasia, match the structural properties of native vessels, and allow for regeneration of arterial tissue. Electrospun recombinant human tropoelastin (rTE) as a medial component of a vascular graft scaff...
