چکیده
As climate change debate is rapidly evolving, we hear a multitude of voices: different actors aregetting involved around addressing the challenges, setting priorities for new knowledge, andframing key questions and actions. Whose voices are these? And how are they “translating” eachother’s knowledge? In order to answer these questions, it is necessary to study how climateknowledge, which has its origin in “objective” scientific discourse, is transmitted to public andpolitical argumentative or action-oriented discourse. How do actors at different levels constructtheir climate politics linguistically? The interdisciplinary research project to which this paper isrelated aims to unpack this polyphonic discourse. In the present contribution, an analysis of adocument produced by the Inter-governmental Panel on Climate Change (IPCC) is undertaken:the “Summary for policymakers” with the main IPCC findings from 2007. This document takesclimate research findings as a point of departure and puts an emphasis on the need of adaptationand political action. Dans les débats sur le changement climatique, une multitude de voix se font entendre : différentsacteurs s’attellent aux défis, définissent les priorités pour de nouvelles connaissances etfournissent un cadre pour les questions et actions clés. À qui appartiennent ces voix ? Commenttraduisent-elles leurs connaissances respectives ? Afin de répondre à ces questions, il estnécessaire d’étudier comment le changement climatique, qui a son origine dans un discoursscientifique « objectif », est transposé en un discours argumentatif et orienté vers l’action.Comment les acteurs construisent-ils linguistiquement leur agenda climatique ? Le projetinterdisciplinaire auquel cet article est lié a pour but de dévoiler ce discours polyphonique. Dansla présente contribution sera entreprise une analyse portant sur un document produit par leIntergovernmental Panel on Climate Change (IPCC), « Summary for policymakers », contenant lesrésultats principaux de l’IPCC de 2007. Ce document prend les résultats scientifiques commepoint de départ et porte une attention particulière à la nécessité de l’adaptation et de l’actionpolitique.

Kinetics of Isomerization and Inversion of Aspartate 58 of αA-Crystallin Peptide Mimics under Physiological Conditions
Although proteins consist exclusively of L-amino acids, we have reported that aspartyl (Asp) 58 and Asp 151 residues of αA-crystallin of eye lenses from elderly cataract donors are highly inverted and isomerized to D-β, D-α and L-β-Asp residues through succinimide intermediates. Of these Asp isomers, large amounts of D-β- and L-β-isomers are present but the amount of D-α-isomer is not significa...

متن کاملRacemization at the Asp 58 residue in αA‐crystallin from the lens of high myopic cataract patients
Post-translational modifications in lens proteins are key causal factors in cataract. As the most abundant post-translational modification in the lens, racemization may be closely related to the pathogenesis of cataract. Racemization of αA-crystallin, a crucial structural and heat shock protein in the human lens, could significantly influence its structure and function. In previous studies, ele...
متن کاملChanges of secondary structure detected by laser Raman spectroscopy in model peptides of human alphaA-crystallin due to substitution of D-aspartyl residues for L-aspartyl residues.
PURPOSE We have found that two aspartyl (Asp-151 and Asp-58) residues of alphaA-crystallin are inverted and isomerized to the biologically uncommon D-beta-Asp residues during aging. In order to elucidate the correlation between the formation of the D-beta-Asp isomer and the environment surrounding the Asp in the protein, we performed a Raman spectroscopic study using two synthetic peptides: T6 ...

Although L-amino acids were selected as main constituents of peptides and proteins during chemical evolution, D-aspartyl (Asp) residue is found in a variety of living tissues. In particular, D-β-Asp is thought to be stable than any other Asp isomers, and this could be a reason for gradual accumulation in abnormal proteins and peptides to modify their structures and functions. It is predicted th...

The genus Acinetobacter comprises several groups of closely related species, including the Acinetobacter calcoaceticus-Acinetobacter baumannii complex (1) and a number of hemolytic species (2). Currently, the A. calcoaceticus-A. baumannii complex comprises five validly named species, including A. calcoaceticus, A. baumannii, A. pittii, and A. nosocomialis (3); the recently named species A. seif...
