Predicting functional outcomes from spinal cord injury (SCI) at the acute setting is important for patient management. This work investigated the relationship of early magnetic resonance imaging (MRI) biomarkers in a rat model of cervical contusion SCI with long-term functional outcome and tissue sparing. Forty rats with contusion injury at C5 at either the spinal cord midline (bilateral) or over the lateral cord (unilateral) were examined using in vivo multi-modal quantitative MRI at 1 day post-injury. The extent of T2-weighted hyperintensity reflecting edema was greater in the bilateral model compared with the unilateral injury. Diffusion tensor imaging (DTI) …

Hybrid scaffolds of bioactive glass (BG) and silk fibroin (SF) were fabricated. 70S30C (70% mol Si, 30% mol Ca) BG is a ceramic biomaterial with natural bone bonding and osteoconductivity potentials. SF is a natural polymer from the silk cocoon of bombyx mori with many desirable properties for tissue engineering applications. Hybridisation between these two biomaterials could mitigate the brittle characteristic of ceramic, enabling the scaffold to resist cyclic load better. This study varied the ratio between BG and SF (BG:SF; 100:0, 95:5, 90:10, 85:15, 80:20, 0:100) and characterized the scaffolds, noting the difference between the scaffolds as a result …
