Genetic engineering and the world trade system

While the WTO agreements do not regulate the use of biotechnology per se, their rules can have a profound impact on the use of the technology for both commercial and non-commercial purposes. This book seeks to identify the challenges to international trade regulation that arise from biotechnology. The contributions examine whether existing international obligations of WTO Members are appropriate to deal with the issues arising for the use of biotechnology and whether there is a need for new international legal instruments, including a potential WTO Agreement on Biotechnology. They combine various perspectives on and topics relating to genetic engineering and trade, including human rights and gender; intellectual property rights; traditional knowledge and access and benefit sharing; food security, trade and agricultural production and food safety; and medical research, cloning and international trade.

Cell and matrix morphology in articular cartilage from adult human knee and ankle joints suggests depth-associated adaptations to biomechanical and anatomical roles

OBJECTIVE Marked differences exist between human knee and ankle joints regarding risks and progression of osteoarthritis (OA). Pathomechanisms of degenerative joint disease may therefore differ in these joints, due to differences in tissue structure and function. Focussing on structural issues which are design goals for tissue engineering, we compared cell and matrix morphologies in different anatomical sites of adult human knee and ankle joints. METHODS Osteochondral explants were acquired from knee and ankle joints of deceased persons aged 20 to 40 years and analyzed for cell, matrix and tissue morphology using confocal and electron microscopy and unbiased stereological methods. Variations associated with joint (knee versus ankle) and biomechanical role (convex versus concave articular surfaces) were identified by 2-way analysis of variance and post-hoc analysis. RESULTS Knee cartilage exhibited higher cell densities in the superficial zone than ankle cartilage. In the transitional zone, higher cell densities were observed in association with convex versus concave articular surfaces, without significant differences between knee and ankle cartilage. Highly uniform cell and matrix morphologies were evident throughout the radial zone in the knee and ankle, regardless of tissue biomechanical role. Throughout the knee and ankle cartilage sampled, chondron density was remarkably constant at approximately 4.2×10(6) chondrons/cm(3). CONCLUSION Variation of cartilage cell and matrix morphologies with changing joint and biomechanical environments suggests that tissue structural adaptations are performed primarily by the superficial and transitional zones. Data may aid the development of site-specific cartilage tissue engineering, and help identify conditions where OA is likely to occur.

Transition and Justice: An Introduction

Since the end of the Cold War, political new beginnings have increasingly been linked to questions of transitional justice. The contributions to this collection examine a series of cases from across the African continent where peaceful ‘new beginnings’ have been declared after periods of violence and where transitional justice institutions played a role in defining justice and the new socio-political order. Three issues seem to be crucial to the understanding of transitional justice in the context of wider social debates on justice and political change: the problem of ‘new beginnings’, of finding a foundation for that which explicitly breaks with the past; the discrepancies between lofty promises and the messy realities of transitional justice in action; and the dialectic between logics of the exception and the ordinary, employed to legitimize or resist transitional justice mechanisms. These are the particular focus of this Introduction.

Shaping EU trade agreements to support human rights

Trade between Europe and developing countries should be shaped such that market shares are just and trade flows foster sustainable development. But this is not always the case. While developing countries have much to gain from trade, they can also suffer serious losses. This is especially apparent with regard to food security, which often depends largely on smallholders and informal markets in poorer countries. This policy brief sketches the link between trade and the right to food, and describes how integration of Human Rights Impact Assessments in EU trade policy can help ensure sustainable trade regimes that do not cause undue harm.
