Reclaiming the Radical in Universal Human Rights: Universality as Universalisation

The universality of human rights has been a fiercely contested issue throughout their history. This article contributes to scholarly engagements with the universality of human rights by proposing a re-engagement with this concept in a way that is compatible with the aims of radical politics. Instead of a static attribute or characteristic of rights this article proposes that universality can be thought of as, drawing from Judith Butler, an ongoing process of universalisation. Universality accordingly emerges as a site of powerful contest between competing ideas of what human rights should mean, do or say, and universal concepts are continually reworked through political activity. This leads to a differing conception of rights politics than traditional liberal approaches but, moreover, challenges such approaches. This understanding of universality allows human rights to come into view as potentially of use in interrupting liberal regimes and, crucially, opens possibilities to reclaim the radical in rights.

After the Critique of Rights: For a Radical Democratic Theory and Practice of Human Rights

The critique of human rights has proliferated in critical legal thinking over recent years, making it clear that we can no longer uncritically approach human rights in their liberal form. In this article I assert that after the critique of rights one way human rights may be productively re-engaged in radical politics is by drawing from the radical democratic tradition. Radical democratic thought provides plausible resources to rework the shortcomings of liberal human rights, and allows human rights to be brought within the purview of a wider political project adopting a critical approach to current relations of power. Building upon previous re-engagements with rights using radical democratic thought, I return to the work of Ernesto Laclau and Chantal Mouffe to explore how human rights may be thought as an antagonistic hegemonic activity within a critical relation to power, a concept which is fundamentally futural, and may emerge as one site for work towards radical and plural democracy. I also assert, via Judith Butler's model of cultural translation, that a radical democratic practice of human rights may be advanced which resonates with and builds upon already existing activism, thereby holding possibilities to persuade those who remain sceptical as to radical re-engagements with rights.

Interaction of glucose and long chain fatty acids (C18) on antioxidant defences and free radical damage in porcine vascular smooth muscle cells in vitro.

Aims/hypothesis: Abnormalities of glucose and fatty acid metabolism in diabetes are believed to contribute to the development of oxidative stress and the long term vascular complications of the disease therefore the interactions of glucose and long chain fatty acids on free radical damage and endogenous antioxidant defences were investigated in vascular smooth muscle cells. Methods: Porcine vascular smooth muscle cells were cultured in 5 mmol/l or 25 mmol/l glucose for ten days. Fatty acids, stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2) and gamma-linolenic acid (18:3) were added with defatted bovine serum albumin as a carrier for the final three days. Results. Glucose (25 mmol/l) alone caused oxidative stress in the cells as evidenced by free radical-mediated damage to DNA, lipids, and proteins. The addition of fatty acids (0.2 mmol/l) altered the profile of free radical damage; the response was J-shaped with respect to the degree of unsaturation of each acid, and oleic acid was associated with least damage. The more physiological concentration (0.01 mmol/l) of gamma-linolenic acids was markedly different in that, when added to 25 mmol/l glucose it resulted in a decrease in free radical damage to DNA, lipids and proteins. This was due to a marked increase in levels of the antioxidant, glutathione, and increased gene expression of the rate-limiting enzyme in glutathione synthesis, gamma-glutamylcysteine synthetase. Conclusion/Interpretation: The results clearly show that glucose and fatty acids interact in the production of oxidative stress in vascular smooth muscle cells.
