PROPOREMOS NESTE TRABALHO EFETUAR A ANÁLISE TENSIVA DE TRÊS TIPOS DE TEXTOS QUE PERTENCEM AO DISCURSO CIENTÍFICO LATO SENSU DA ÁREA ASTROFÍSICA: O DISCURSO DA CIÊNCIA EM LABORATÓRIO, DA CIÊNCIA EM ARTIGOS ESPECIALIZADOS E DA CIÊNCIA EM ARTIGOS DE VULGARIZAÇÃO. OS TRÊS DISCURSOS PERTENCEM À MESMA VONTADE DE CONSEGUIR DESCREVER AS IMAGENS, SEGUNDO VÁRIAS MODALIDADES. POR ISSO SE PODEM CHAMAR DISCURSOS DE LEGENDA. ISSO SIGNIFICA QUE PARTICIPAM DO MESMO MOVIMENTO QUE TENTA DEFINIR A COMPOSIÇÃO E O SENTIDO DAS IMAGENS. O PROCESSO É MAIS AMPLO NO CASO DO DISCURSO DE LABORATÓRIO, JÁ QUE CORRESPONDE À PRIMEIRA TENTATIVA DE INTERPRETAÇÃO DAS IMAGENS, ENQUANTO OS DEMAIS, SENDO ESCRITOS EM ARTIGOS, ESTÃO NUM ESTÁGIO POSTERIOR, NO QUAL AS FORMAS ESTÃO ESTABILIZADAS. O PROPÓSITO É DE ANALISAR OS TRÊS DISCURSOS COM AS FERRAMENTAS PROPOSTAS PELA SEMIÓTICA TENSIVA, TAL COMO FOI DESENVOLVIDA POR CLAUDE ZILBERBERG E JACQUES FONTANILLE. O OBJETIVO CORRESPONDE A ESTABELECER OS CRITÉRIOS TENSIVOS SOBRE OS QUAIS PODERÍAMOS EFETUAR UMA DIFERENCIAÇÃO GENÉRICA ENTRE OS DISCURSOS ANALISADOS, DIFERENCIAÇÃO ESTABELECIDA SOBRE UMA BASE TENSIVA. UM OUTRO OBJETIVO, QUE SERIA MAIS LATERAL, SERÁ TAMBÉM RECONHECER ALGUMAS PERGUNTAS ESPECÍFICAS QUE PROPÕE O OBJETO À SEMIÓTICA TENSIVA. PRETENDEMOS ENTÃO DESEMBOCAR EM UMA SISTEMATIZAÇÃO DAS DIFERENÇAS ENTRE ESTES DISCURSOS, QUE ESTARIA ALÉM DAS CONSIDERAÇÕES ARGUMENTATIVAS OU FIGURATIVAS, E SUSTENTARIA POR CONSEGUINTE OS MAIS RECENTES DESENVOLVIMENTOS DA SEMIÓTICA, APLICADA À IMAGEM CIENTÍFICA. UMA CARACTERIZAÇÃO TENSIVA DESSES TEXTOS AJUDARIA A COMPREENSÃO DO CAMPO DISCURSIVO ASTROFÍSICO QUE IRIA ALÉM DA DISTINÇÃO A PRIORI, BASEADA NO LUGAR DE ENUNCIAÇÃO E NO TIPO DE RECEPÇÃO. UMA ANÁLISE MAIS PROFUNDA DAS ESTRUTURAS TENSIVAS DE CADA UM LEVARIA EM CONSIDERAÇÃO OS TIPOS DE APRESENTAÇÃO E DE DINAMISMO DOS CONTEÚDOS PRÓPRIOS PARA CADA TIPO, OFERECENDO UMA BASE ESTÁVEL DE DIFERENCIAÇÃO. POR ISSO, USAREMOS CINCO CONCEITOS FUNDAMENTAIS DA SEMIÓTICA TENSIVA: OS MODOS DE PRESENÇA, OS MODOS DE EFICIÊNCIA, OS MODOS DE EXISTÊNCIA, OS MODOS DE JUNÇÃO E A FIDÚCIA. O ÂMBITO SEMIÓTICO NO QUAL SE COLOCA A NOSSA PESQUISA, JÁ BASTANTE DESENVOLVIDO, É O DA SEMIÓTICA DA IMAGEM CIENTÍFICA. APOIANDO-NOS EM DONDERO, BORDRON E LATOUR, ESCLARECEREMOS O LUGAR DO NOSSO TRABALHO ENTRE AS QUESTÕES RELATIVAS AO CAMPO DE ESTUDO SEMIÓTICO DAS IMAGENS E DOS DISCURSOS CIENTÍFICOS. O ÂMBITO PARTICULAR NO QUAL NOS SITUAMOS NA SEMIÓTICA DAS IMAGENS CIENTÍFICAS É O DAS CHAMADAS “PRÁTICAS DE INSTANCIAÇÃO” EM QUE SE RECONHECEM TRÊS ETAPAS QUE ESTRUTURAM AS PESQUISAS CIENTÍFICAS EM GERAL: INTERROGAÇÃO, ESTABILIZAÇÃO E INSTITUCIONALIZAÇÃO (DONDERO, 2010). AS ANÁLISES QUE FAREMOS PRETENDEM DESCREVER E DISTINGUIR OS PROCESSOS DO DINAMISMO DOS CONTEÚDOS IMPLICADOS NESTES TRÊS NÍVEIS DO FLUXO DA PESQUISA. SOB OS PREÂMBULOS DA ANÁLISE TENSIVA, PRETENDEMOS EXPLICITAR EM PRIMEIRO LUGAR ALGUMAS TENDÊNCIAS DOS DISCURSOS NO NÍVEL MACROSCÓPICO DA PESQUISA E ALGUMAS ORIENTAÇÕES PARTICULARES DOS DISCURSOS ISOLADOS NO NÍVEL MICROSCÓPICO. POR FIM, CONSEGUIREMOS ORGANIZAR O CAMPO DISCURSIVO ANALISADO EM FUNÇÃO DE DOIS ELEMENTOS. POR UM LADO, SEGUINDO LOUIS HÉBERT (2009), DISTINGUIREMOS ENTRE CARÁTER ANALÍTICO OU SINTÉTICO DA COMPOSIÇÃO DO VALOR DOS OBJETOS. POR OUTRO LADO, EFETUAREMOS A DIFERENCIAÇÃO ENTRE DOIS CAMPOS, O SABER E O CRER, NOS QUAIS DE DESENVOLVEM A IMPLICAÇÃO E A CONCESSÃO, AS OPERAÇÕES LÓGICAS RECONHECIDAS PELA SEMIÓTICA TENSIVA. FINALMENTE SERÃO IDENTIFICADAS OS MOVIMENTOS TENSIVOS PRÓPRIOS PARA CADA DISCURSO. [less ▲]

This essay discusses the changing nature of (Flemish) poetry at the beginning of the 21ste century: the genre appears to become increasingly obsolete and unpopular; on the other hand, it continues to show an unexpected vitality. This may be explained by the fact that both poetry and the inescapable frailty of human identifications are two faces of the same coin. [less ▲]

We discuss an ASCA observation of the eccentric WC8+O7.5III binary gamma[SUP]2[/SUP]Velorum near apastron. The X-ray spectrum is compared with two previous observations obtained when the system was near periastron. All three spectra display a hard-emission component that undergoes strong variability over the orbital cycle. The properties of the hard X-ray emission of gamma[SUP]2[/SUP]Vel are constrained by taking into account the contribution from contaminating soft X-ray sources in the vicinity of gamma[SUP]2[/SUP]Vel. We find that the observed variations are in qualitative agreement with the predictions of colliding wind models. We investigate for the first time the effect of uncertainties in the chemical composition of the X-ray emitting plasma on our understanding of the high-energy properties of the wind interaction region. Our results indicate that these uncertainties significantly affect the derived shock temperature and absorption column, but play a smaller role in determining the intrinsic X-ray luminosity of the colliding wind zone. We further find that the intrinsic luminosity from the hard X-ray component in gamma[SUP]2[/SUP]Vel does not follow the 1/D distance relation expected from simple models of adiabatic shocks.

Abstract – ASCID: the core of 12 factors that explain behavior in patient education. Introduction: Professionals involved in Patient Education need to have a good understanding of the (numerous) factors that affect, in a person, her becoming aware, then her decision, then her putting it into practice in a lasting and efficient way. For this purpose, we propose a model we have developed during several years in CERES (University of Liège) as well as in DPSS (University of Paris 13), named “Factors of production and perseveration in actions”. If these factors are designated by the first letters of their names, at the heard of the model stands the acronym ASCID (Attitudes, Skills, Cognition, Identity, Decision). Objectives: This model, conceived for health and environment education is not limited to therapeutic patient education, but it fits it very well. The interest and the fecundity of this model have been put to test during more than 25 years with cohorts of students and professionals involved in TPE to analyze situations, cases, and to conceive relevant course of action for the educator and the patient. Description: Methods of diagnostic and of action in TPE superimposed themselves to the model of patient functioning. To help readers assimilate this complex model, we start with a familiar case (AIDS) and we will use frequently cases to illustrate theoretical concepts. [less ▲]

Ascididemin and Meridine are two marine compounds with pyridoacridine skeletons known to exhibit interesting antitumour activities. These molecules have been reported to behave like DNA intercalators. In this study, dialysis competition assay and mass spectrometry experiments were used to determine the affinity of ascididemin and meridine for DNA structures among duplexes, triplexes, quadruplexes and single-strands. Our data confirm that ascididemin and meridine interact with DNA but also recognize triplex and quadruplex structures. These molecules exhibit a significant preference for quadruplexes over duplexes or single-strands. Meridine is a stronger quadruplex ligand and therefore a stronger telomerase inhibitor than ascididemin (IC50= 11 and > 80 mu M, respectively in a standard TRAP assay). (c) 2005 Elsevier B.V.

Background NEUROG3 is a key regulator of pancreatic endocrine cell differentiation in mouse, essential for the generation of all mature hormone producing cells. It is repressed by Notch signaling that prevents pancreatic cell differentiation by maintaining precursors in an undifferentiated state. Results We show herein that, in zebrafish, neurog3 is not expressed in the pancreas and null neurog3 mutant embryos do not display any apparent endocrine defects. The control of endocrine cell fate is instead fulfilled by a couple of bHLH factors, Ascl1b and Neurod1, that are both repressed by Notch signaling. ascl1b is transiently expressed in the mid-trunk endoderm just after gastrulation and is required for the generation of the first pancreatic endocrine precursor cells. Neurod1 is expressed afterwards in the pancreatic anlagen and pursues the endocrine cell differentiation program initiated by Ascl1b. Their complementary role in endocrine differentiation of the dorsal bud is demonstrated by the loss of all hormone-secreting cells following their simultaneous inactivation. This defect is due to a blockage of the initiation of endocrine cell differentiation. Conclusions This study demonstrates that NEUROG3 is not the unique pancreatic endocrine cell fate determinant in vertebrates. A general survey of endocrine cell fate determinants in the whole digestive system among vertebrates indicates that they all belong to the ARP/ASCL family but not necessarily to the Neurog3 subfamily. The identity of the ARP/ASCL factor involved depends not only on the organ but also on the species. One could therefore consider differentiating stem cells into insulin-producing cells without the involvement of NEUROG3 but via another ARP/ASCL factor. [less ▲]

The Greek inscriptions afford several examples of the relationship between Asklepios, the god of medicine, and the human doctors, in Graeco-Roman Antiquity. Many dedications of steles, statues, altars and even sanctuaries were consecrated to Asklepios by doctors. Other physicians have undertaken the offices of zacorate or priesthood in the worship of Asklepios. In some cities, notably at Athens and Ephesos, the doctors sacrificed collectively to the physician-god. The aim of this paper is to explain these cult relations between Asklepios and the doctors. After the Asklepiads, doctors at Kos and Knidos, who were believed to be the descendants of Asklepios, all the ancient doctors were connected with Asklepios by their techne; the physician-god was the divine patron of the physicians. Furthermore although the doctors rejected the divine origin of the diseases, they acknowledged the healing power of the gods, especially Asklepios, and could seek his help. [less ▲]

Hepatocarcinoma cells (TLT) were incubated in the presence of ascorbate and menadione, either alone or in combination. Cell death was only observed when such compounds were added simultaneously, most probably due to hydrogen peroxide (H2O2) generated by ascorbate-driven menadione redox cycling. TLT cells were particularly sensitive to such an oxidative stress due to its poor antioxidant status. DNA strand breaks were induced by this association but this process did not correspond to oligosomal DNA fragmentation (a hallmark of cell death by apoptosis). Neither caspase-3-like DEVDase activity, nor processing of procaspase-3 and cleavage of poly(ADP-ribose) polymerase (PARP) were observed in the presence of ascorbate and menadione. Cell death induced by such an association was actively dependent on protein phosphorylation since it was totally prevented by preincubating cells with sodium orthovanadate, a tyrosine phosphatase inhibitor. Finally, while H2O2, when administered as a bolus, strongly enhances a constitutive basal NF-kappaB activity in TLT cells, their incubation in the presence of ascorbate and menadione results in a total abolition of such a constitutive activity.

Fibronectin and procollagen types I and III are constituents of the extracellular matrix of human fibroblasts. Ultrastructural immunocytochemistry using the peroxidase anti-peroxidase method showed fibronectin and procollagen antibodies reacting in continuous fashion on 10 nm diameter extracellular fibrils on human fibroblasts. Intracellular localization showed an intense accumulation of procollagen within cells cultured under routine conditions. This accumulation appeared almost as if there were a blockade in secretion of procollagen under routine culture conditions. Cells treated with ascorbic acid do not have the dense intracellular accumulation of procollagens seen with the apparent blockade of secretion in cells cultured under routine conditions. Ascorbate treated cells also have a more pronounced extracellular accumulation of matrix fibronectin and procollagen constituents. At the electromicroscopic level a new 40 nm diameter fibril is formed after ascorbic acid treatment of human fibroblasts. Antibody to fibronectin and procollagen I and III are seen binding to the 40 nm diameter fibrils in a periodic or stuttered appearance. The fibronectin and procollagen antibodies react with a 70 nm axial repeat along these 40 nm fibrils formed after ascorbate treatment. These studies suggest that under routine culture conditions "precursor" fibrils of fibronectin and procollagen are formed. Ascorbic acid treatment leads to enhanced matrix formation. Ultrastructural studies clearly show antibodies to fibronectin bind to fibronectin on native collagen fibrils formed by human fibroblasts cultured with ascrobic acid. Lastly there is an asymmetric or 70 nm axial periodic distribution of fibronectin along these definitive or mature collagen fibrils formed after ascorbic acid treatment. [less ▲]
