Este texto plantea la posibilidad de recuperar el nos-otros-originario como clave para la superación del «sufrimiento inútil» del sujeto; de este modo, muestra al nos-otros-originario como una zona de protección de los derechos de el-otro, hace una crítica en contra del nos-otros-caído como vulnerador de derechos fundamentales, y aborda la posibilidad de recuperar el nos-otros-originario a través de una consumación definitiva de la "justicia".

Delayed mortality associated with discarded crabs and fishes has ordinarily been observed through tag and recovery studies or during prolonged holding in deck tanks, and there is need for a more efficient assessment method. Chionoecetes bairdi (Tanner crab) and C. opilio (snow crab) collected with bottom trawls in Bering Sea waters off Alaska were evaluated for reflexes and injuries and held onboard to track mortality. Presence or absence of six reflex actions was determined and combined to calculate a reflex impairment index for each species. Logistic regression revealed that reflex impairment provided an excellent predictor of delayed mortality in C. opilio (91% correct predictions). For C. bairdi, reflex impairment, along with injury score, resulted in 82.7% correct predictions of mortality, and reflex impairment alone resulted in 79.5% correct predictions. The relationships between reflex impairment score and mortality were independent of crab gender, size, and shell condition, and predicted mortality in crabs with no obvious external damage. These relationships provide substantial improvement over earlier predictors of mortality and will help to increase the scope and replication of fishing and handling experiments. The general approach of using reflex actions to predict mortality should be equally valuable for a wide range of crustacean species.

Previous studies have demonstrated that germinal vesicle of amphibian oocyte contains small nuclear ribonucleoprotein polypeptide C (SNRPC). In this study, a putative member of SNRPC was identified from Carassius auratus gibelio oocyte cDNA library. Its full-length cDNA has an open reading frame of 201 nt for encoding a peptide of 66 an, a short 5'-UTR of 19 nt and a long 3'-UTR of 347 nt including a polyadenylation signal and poly- (A) tail, and the deduced amino acid sequence has 47% identity with the C-terminal of the zebrafish small nuclear ribonucleoprotein polypeptide C. Western blot analysis revealed its oocyte-specific expression. Immunofluorescence localization indicated that its gene product localized to numerous nucleoli within the oocytes and showed dynamic changes with the nucleoli during oocyte maturation. RT-PCR and Western blot analysis further revealed its constant presence in the oocytes and in the embryos until hatching. The data suggested that the newly identified CagOSNRPC might be a nucleolar protein. (c) 2006 Elsevier Inc. All rights reserved.

研究低剂量12C6+离子全身辐照对小鼠胸腺、脾脏细胞周期进程及DNA伤的影响。以0、10、50、75、100和250mGy12C6+离子全身辐照小鼠,照射后6h处死小鼠,用流式细胞仪检测受辐照小鼠胸腺、脾脏细胞在各细胞周期的百分率,用彗星电泳技术检测受辐照小鼠胸腺脾脏细胞的拖尾率和拖尾长度。所有照射组G0/G1期胸腺细胞百分率明显低于对照组,(p<0.05),10~100mGy照射组S期胸腺细胞百分率显著高于对照组(p<0.01),所有照射组(G2/M)期胸腺细胞百分率明显高于对照组(p<0.05);所有照射组G0/G1期脾细胞百分率明显高于对照组(p<0.01),S期脾细胞百分率显著低于对照组(p<0.05)。彗星电泳结果显示低剂量12C6+离子辐照以剂量依赖的方式引起小鼠胸腺脾脏细胞DNA移长度及拖尾率的增加。低剂量的碳离子辐射可促进小鼠胸腺细胞DNA成,对小鼠脾脏细胞产生抑制作用,使其发生G1期阻滞;同时对胸腺及脾脏细胞造成具有明显剂量效应关系的DNA伤。

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.

In the framework of the European project Platform of Local Authorities and Communicators Engaged in Science (PLACES), we analyse the articulations between scientifi c communication, public perception of science, processes of citizen participation and apropiation of space, based on a case study of the inhabitants of Teruel city, Autonomous Community of Aragon, Spain. On the interrelationships between these issues, there are a number of contradictions, such as the difference between a high interest for information about science and technology and a low level of recognition and interaction with local institutions involved in those activities, the complex conceptualization of scientifi c space in relation to the “public-private” pair, or an articulation of a claiming civic rethoric and an insuffi cient co-responsibility. We conclude that, in a local context, the dimension of territoriality and, in particular, the identifi cation with the town, is a central mediation for activating citizen participation as part of processes of appropriation of space for setting up cities of scientifi c culture.
