Abstract
In the current research, the nanofibrous neural channels were produced by electrospinning of PCL/Gelatin solution loaded with Calendula officinalis extract. The produced scaffolds properties were studied using various in vitro characterization methods. Then, the conduits’ healing potential was investigated in a rat model of PNS injury. In vitro results showed that scaffolds were not toxic and quenched DPPH free radicals. In addition, the extract-loaded conduits exhibited significant anti-inflammatory activity. In vivo study showed that the regular treadmill exercise significantly improved the healing efficacy of the Calendula officinalis-delivering conduits by upregulating BDNF and GFAP proteins.
期刊介绍：
The use and importance of biomedical polymers, especially in pharmacology, is growing rapidly. The Journal of Bioactive and Compatible Polymers is a fully peer-reviewed scholarly journal that provides biomedical polymer scientists and researchers with new information on important advances in this field. Examples of specific areas of interest to the journal include: polymeric drugs and drug design; polymeric functionalization and structures related to biological activity or compatibility; natural polymer modification to achieve specific biological activity or compatibility; enzyme modelling by polymers; membranes for biological use; liposome stabilization and cell modeling. This journal is a member of the Committee on Publication Ethics (COPE).
