| 1 | CELL ADHESION AND SURFACE PROPERTIES OF POLYSTYRENE SURFACES GRAFTED WITH POLY(N-ISOPROPYLACRYLAMIDE)显示文摘Cell adhesion plays a key role in various aspects of biological and medical sciences. In this study, poly(Nisopropylacrylamide)(PNIPAM) was grafted on polystyrene surfaces using different solvents under UV radiation.Moreover, the relation between surface roughness and cell adhesion were evaluated by gravimetric, SEM, AFM, contact angle measurement and cellular analyses. The gravimetric analysis clearly indicated an increase in the grafting by adding10% methanol to water. The study of surface topography by AFM images showed an increase in the surface roughness and as a result of which, a decrease in wettablity was observed. At 37 C, epithelial cells were well attached and proliferated on the grafted surfaces, while these cells were spontaneously detached below 32 °C in the absence of any enzymes. Moreover,MTT assay and SEM images indicated good cell viability and an increase in cell adhesion caused by the roughness increase. The results of this study reveal the great potential of PNIPAM-grafted polystyrene for being used in the biomedical fields such as drug delivery systems, tissue engineering and cell separation. | Esmaeil Biazar Mohammad Taghi Khorasani Morteza Daliri Joupari | 2013 | Chinese Journal of Polymer Science2013，31，11： | 3 |
| 2 | Efficacy of nanofibrous conduits in repair of longsegment sciatic nerve defects显示文摘Our previous studies have histomorphologically confirmed that nanofibrous poly(3-hydroxybutyrateco-3-hydroxyvalerate) conduit can be used to repair 30-mm-long sciatic nerve defects.However,the repair effects on rat behaviors remain poorly understood.In this study,we used nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous sciatic nerve to bridge 30-mm-long rat sciatic nerve gaps.Within 4 months after surgery,rat sciatic nerve functional recovery was evaluated per month by behavioral analyses,including toe out angle,toe spread analysis,walking track analysis,extensor postural thrust,swimming test,open-field analysis and nociceptive function.Results showed that rat sciatic nerve functional recovery was similar after nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit and autologous nerve grafting.These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) conduit is suitable in use for repair of long-segment sciatic nerve defects. | Esmaeil Biazar Saeed Heidari Keshel Majid Pouya | 2013 | Neural Regeneration Research2013，8，27： | 3 |

| 7 | Nanofibrous nerve conduits for repair of 30-mm-long sciatic nerve defects显示文摘It has been confirmed that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit can promote peripheral nerve regeneration in rats. However, its efficiency in repair of over 30-mm-long sciatic nerve defects needs to be assessed. In this study, we used a nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit to bridge a 30-mm-long gap in the rat sciatic nerve. At 4 months after nerve conduit implantation, regenerated nerves were macroscopically observed and histologically assessed. In the nanofibrous graft, the rat sciatic nerve trunk had been reconstructed by restoration of nerve continuity and formation of myelinated nerve fiber. There were Schwann cells and glial cells in the regenerated nerves. Masson's trichrome staining showed that there were no pathological changes in the size and structure of gastrocnemius muscle cells on the operated side of rats. These findings suggest that nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit is suitable for repair of long-segment sciatic nerve defects. | Esmaeil Biazar Saeed Heidari Keshel Majid Pouya Hadi Rad Melody Omrani Nava Mohammad Azarbakhsh Shirin Hooshmand | 2013 | Neural Regeneration Research2013，8，24： | 1 |
