Tomorrow’s Silk Road: Assessing an EU-China Free Trade Agreement

This book provides an independent and in-depth contribution on the status of bilateral economic exchanges and persistent trade barriers between the European Union and China. A second objective is to encourage a frank and open dialogue, based on a scientific evaluation and without prejudice, of the possibility of a preferential trade agreement between the two sides. The study, commissioned by the Foreign Trade Association, was carried out by CEPS, in cooperation with the World Trade Institute (WTI) at the University of Bern. Jacques Pelkmans, CEPS Senior Research Fellow, served as overall study leader and Joseph Francois, Managing Director and Professor of Economics at the World Trade Institute, led the WTI team.

Tomorrow's silk road: Assessing an EU-China Free Trade Agreement.

Foreword. The Foreign Trade Association, which represents the European and international distribution and retail sector, commissioned this study in light of the importance of China as a sourcing country and its attractiveness as a rapidly growing consumer market. We believe that open borders and free trade can contribute to a broader choice and lower costs for consumers and create growth and employment in both Europe and China. This independent study aims to provide an in-depth contribution on the status of bilateral economic exchanges and persistent trade barriers that exist between the European Union and China. The second objective of the report is to encourage a frank and open dialogue, based on a scientific evaluation and without prejudice, on the possibility of a preferential trade agreement between the two sides. This study should be read by anyone who is interested in economic relations between the EU and China and in trade policy in general. The report provides many interesting findings and raises a number of surprising points. Overall, this study is one of the most significant contributions to the discourse on EU-China relations in recent years. We hope that this study will stimulate fresh thoughts on the benefits of closer future cooperation between two regions that have been interlinked since the times of antiquity and the first Silk Road.

Genetically engineered silk and genipin-enhanced fibrin hydrogel for annulus fibrosus repair

INTRODUCTION: Around 80% of people are affected by low back pain at least once in their life, often caused by trauma provoking intervertebral disc (IVD) herniation and/or IVD degeneration. Apart from some promising approaches for nucleus pulposus repair, so far no treatment or repair is available for the outer fibrous tissue, annulus fibrosus (AF). We aimed for sealing and repairing an AF injury in a bovine IVD organ culture model in vitro over 14 days under different loading conditions. For this purpose, a silk fleece composite from Bombyx mori silk was combined with genipin-enhanced fibrin hydrogel [1]. METHODS: Bovine IVDs of 12-17 months old animals were isolated by first removing all surrounding tissue, followed by cutting out the IVDs [2]. Culturing of discs occurred in high glucose Dulbecco's Modified Eagle Medium (HG-DMEM) supplemented with 5% serum as previously described. On the next day, injury was induced using a 2mm biopsy punch (Polymed, Switzerland). The formed cavity was filled with (0.4%) genipin-enhanced human based fibrin hydrogel (35- 55mg/mL human fibrinogen, Baxter, Austria) and sealed with a silk fleece-membrane composite (Spintec Engineering, Germany). Different culture conditions were applied: free swelling, static diurnal load of 0.2MPa for 8h/d and complex loading at 0.2MPa compression combined with ± 2° torsion at 0.2Hz for 8h/d. Complex loading was applied by a custom built 2 degree of freedom bioreactor [3]. After 14 days of culture cell activity was determined with resazurin assay. Additionally, glycosaminoglycan (dimethyl-methylene blue), DNA (Hoechst) and collagen content (hydroxy-proline) were determined. Finally, real-time qPCR of major IVD marker genes was performed. RESULTS: The silk seal closing the injury site could successfully withstand the forces of all three loading conditions with no misplacement over the two weeks’ culture. Nevertheless, disc height of the repaired discs did not significantly differ from the injured group. The disc phenotype could be maintained as demonstrated by biochemical analysis of gene expression, cell activity, DNA-, collagen- and GAG content. The silk itself was evaluated to be highly biocompatible for hMSC, as revealed by cytotoxicity assays. DISCUSSION & CONCLUSIONS: The silk can be considered a highly-elastic and biocompatible material for AF closure and the genipin-enhanced fibrin hydrogel has also good biomechanical properties. However, the cyto-compatibility of genipin seems rather poor and other hydrogels and/or cross-linkers should be looked into. REFERENCES: 1 C.C. Guterl et al.
