Heat shock proteins (chaperones) in fish and shellfish and their potential role in relation to fish health: a review

JOURNAL OF FISH DISEASES, Issue 10 2010
R J Roberts
Abstract Heat shock proteins (HSPs), also known as stress proteins and extrinsic chaperones, are a suite of highly conserved proteins of varying molecular weight (c. 16,100 kDa) produced in all cellular organisms when they are exposed to stress. They develop following up-regulation of specific genes, whose transcription is mediated by the interaction of heat shock factors with heat shock elements in gene promoter regions. HSPs function as helper molecules or chaperones for all protein and lipid metabolic activities of the cell, and it is now recognized that the up-regulation in response to stress is universal to all cells and not restricted to heat stress. Thus, other stressors such as anoxia, ischaemia, toxins, protein degradation, hypoxia, acidosis and microbial damage will also lead to their up-regulation. They play a fundamental role in the regulation of normal protein synthesis within the cell. HSP families, such as HSP90 and HSP70, are critical to the folding and assembly of other cellular proteins and are also involved in regulation of kinetic partitioning between folding, translocation and aggregation within the cell. HSPs also have a wider role in relation to the function of the immune system, apoptosis and various facets of the inflammatory process. In aquatic animals, they have been shown to play an important role in health, in relation to the host response to environmental pollutants, to food toxins and in particular in the development of inflammation and the specific and non-specific immune responses to bacterial and viral infections in both finfish and shrimp. With the recent development of non-traumatic methods for enhancing HSP levels in fish and shrimp populations via heat, via provision of exogenous HSPs or by oral or water administration of HSP stimulants, they have also, in addition to the health effects, been demonstrated to be valuable in contributing to reducing trauma and physical stress in relation to husbandry events such as transportation and vaccination.

Externalised Justice and Democratisation: Lessons from the Pinochet Case

POLITICAL STUDIES, Issue 2 2006
Madeleine Davis
The attempt to try Pinochet in Spain exemplified and publicised a trend to use ,externalised justice' to tackle impunity for human rights crimes. It also demonstrated the possibilities and limitations of externalised justice initiatives, in terms of securing democracy at the national level, and of advancing accountability for serious crimes under international law. In Chile, Argentina and Spain the Pinochet affair served to restart stalled impulses towards accountability, accelerate democratic reform and challenge the legitimacy of compromises conceded during earlier democratic transitions. With regard to the wider role of international law in limiting impunity, expectations for rapid or consistent replication of ,the Pinochet precedent' have not been met. Despite some notable achievements, the exercise of universal jurisdiction by national courts remains inconsistent and controversial. The International Criminal Court (ICC) provides a new mechanism for external justice. An aggressive US campaign to undermine it, and to reverse progress in international law, is a serious obstacle to fulfilment of the ICC's enforcement role. However, at the domestic level the ICC may have similar indirect effects to the Pinochet litigation, boosting domestic enforcement prospects and strengthening democratic commitment. In both cases the key role for externalised justice is as stimulus or back-up. This suggests that progress in tackling impunity depends on incremental and dynamic interaction between domestic and international law, and between national and transnational actors. [source]


The Current Situation of Retirement Income Provisions in Japan: Social Security Pension Schemes and Corporate Pension Plans

ASIAN SOCIAL WORK AND POLICY REVIEW, Issue 2 2009
Junichi Sakamoto
Japan has been faced with rapid population ageing for decades. This has continuously reduced the level of social security pension benefits. Based on this it is often said that corporate pension plans should play a wider role forward in providing retirement benefits. However, we also have to know that there is a limit to what corporate pension plans can do in place of the social security pension schemes. In this paper we extract lessons from the history of social security pension schemes in our country and try to define the roles of corporate pension plans and social security pension schemes. In conclusion we should keep adequacy of social security pension benefits even if the contribution rate becomes a bit higher. Corporate pension plans just enrich people's life in retirement. We have to remember that corporate pension plans were not certain means for reducing the poverty in old age and that for this reason social security pension schemes by social insurance were invented.

Not just angiogenesis,wider roles for the angiopoietins

THE JOURNAL OF PATHOLOGY, Issue 4 2003
Pamela F Jones
Abstract Since the discovery of the angiopoietins, much interest has been focused on their biological actions and their potential use as therapeutic targets. It is generally accepted that the angiopoietins play an important role in angiogenesis and hence are described as angiogenic factors. However, it is becoming increasingly clear that this is not their only role and it is likely that the angiopoietins have important roles in a wider range of biological and pathological functions.
