Mediated sacralization and the construction of postmodern communio sanctorum: The case of the Swedish foreign minister anna lindh
2005
In the media age, the linkage between mediated communities and images is established by the sacralization of images. Based on the theoretical insights of Michel Maffesoli and on an influential tradition in French sociology, which includes Emile Durkheim, Georges Bataille, and Rene Girard, this article attempts to apply the theory of sacred images to the empirical analysis of images in the media. The analysis of the Swedish and Finnish newspapers' visual coverage of the assassination of Swedish Foreign Minister Anna Lindh suggests that the process of sacralization is actually performed as a communicative behavior involving the media and the crowd as the main actors and a number of symbols wh…
Humanist Neo-Latin Drama in France
2013
Neo-Latin humanist drama in France offers a fairly modest corpus of texts compared to the production in the rest of Europe. Moreover, humanist drama composed in Latin is not very well known; Latin plays, mostly written by teachers or students in colleges, have for a long time remained in the shadow of vernacular mystery plays, farces and moralities on the one hand, and, from the 1550s onwards, of the first tragedies and comedies written in French on the other. French dramatic writing in the sixteenth century is characterized first of all by the important place occupied by a theatre which was long called 'popular' and 'medieval', but which reached its full maturity between 1450 and 1550. The…
Conscious Entertainment: Commitment in the Reggae Lyrics of Clinton Fearon and Protoje
2016
International audience; This article provides an analysis of the lyrics of Clinton Fearon and Protoje, two major figures of contemporary Jamaican popular music. They are consistently described as committed singers/songwriters and proficient lyricists in a context where reggae music and culture are seen as falling into the excesses of violence and “slackness.” A study of commitment in their respective last two albums will show that despite some contradictions, conscious reggae is still alive today.
Liver fibrosis: Direct antifibrotic agents and targeted therapies
2018
Liver fibrosis and in particular cirrhosis are the major causes of morbidity and mortality of patients with chronic liver disease. Their prevention or reversal have become major endpoints in clinical trials with novel liver specific drugs. Remarkable progress has been made with therapies that efficiently address the cause of the underlying liver disease, as in chronic hepatitis B and C. Highly effective antiviral therapy can prevent progression or even induce reversal in the majority of patients, but such treatment remains elusive for the majority of liver patients with advanced alcoholic or nonalcoholic steatohepatitis, genetic or autoimmune liver diseases. Moreover, drugs that would speed…
TGF-β2 silencing to target biliary-derived liver diseases
2020
ObjectiveTGF-β2 (TGF-β, transforming growth factor beta), the less-investigated sibling of TGF-β1, is deregulated in rodent and human liver diseases. Former data from bile duct ligated and MDR2 knockout (KO) mouse models for human cholestatic liver disease suggested an involvement of TGF-β2 in biliary-derived liver diseases.DesignAs we also found upregulated TGFB2 in liver tissue of patients with primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC), we now fathomed the positive prospects of targeting TGF-β2 in early stage biliary liver disease using the MDR2-KO mice. Specifically, the influence of TgfB2 silencing on the fibrotic and inflammatory niche was analysed on m…
Exploring organ-specific features of fibrogenesis using murine precision-cut tissue slices
2019
Fibrosis is the hallmark of pathologic tissue remodelling in most chronic diseases. Despite advances in our understanding of the mechanisms of fibrosis, it remains uncured. Fibrogenic processes share conserved core cellular and molecular pathways across organs. In this study, we aimed to elucidate shared and organ-specific features of fibrosis using murine precision-cut tissue slices (PCTS) prepared from small intestine, liver and kidneys. PCTS displayed substantial differences in their baseline gene expression profiles: 70% of the extracellular matrix (ECM)-related genes were differentially expressed across the organs. Culture for 48 h induced significant changes in ECM regulation and trig…
Prediction of progressive liver fibrosis in hepatitis C infection by serum and tissue levels of transforming growth factor-beta.
2001
Although many patients with chronic viral hepatitis C infection suffer from progressive liver disease, the rate of fibrosis progression is highly variable and some patients do not show any measurable progression. However, our ability to predict which patients progress is very limited. Since transforming growth factor-beta (TGF-beta) is a key mediator of liver fibrogenesis, we assessed the predictive role of TGF-beta for fibrogenesis in chronic hepatitis C. We studied 39 patients with chronic hepatitis C in whom two liver biopsies were taken at least 12 months apart, and who did not receive therapy during this period. TGF-beta was measured by bioassay and by ELISA in serum samples taken at t…
Hepatocyte-Specific Smad7 Expression Attenuates TGF-β–Mediated Fibrogenesis and Protects Against Liver Damage
2008
Background & Aims The profibrogenic role of transforming growth factor (TGF)-β in liver has mostly been attributed to hepatic stellate cell activation and excess matrix synthesis. Hepatocytes are believed to contribute to increased rates of apoptosis. Methods Primary hepatocyte outgrowths and AML12 cells were used as an in vitro model to detect TGF-β effects on the cellular phenotype and expression profile. Furthermore, a transgenic mouse model was used to determine the outcome of hepatocyte-specific Smad7 expression on fibrogenesis following CCl 4 -dependent damage. Samples from patients with chronic liver diseases were assessed for (partial) epithelial-to-mesenchymal transition (EMT) in h…
Deletion of organic cation transporter Oct3 promotes hepatic fibrosis via upregulation of TGFβ
2019
Organic cation transporters (OCT) are responsible for the intracellular uptake and detoxification of a broad spectrum of endogenous and exogenous substrates. OCTs are downregulated in cholestasis, fibrosis, and hepatocellular carcinoma, but the underlying molecular mechanisms and downstream effects of OCT deletion are unknown. Oct3-knockout ( Oct3−/−; FVB.Slc22a3tm10pb) and wild-type (WT; FVB) mice were subject to escalating doses of carbon tetrachloride (CCl4) or thioacetamide (TAA) for 6 wk to induce advanced parenchymal liver fibrosis. Secondary biliary fibrosis was generated by bile duct ligation. Liver fibrosis was assessed by hydroxyproline determination, quantitative Sirius red morp…
Liver fibrosis induced by hepatic overexpression of PDGF-B in transgenic mice
2006
Background/Aims In hepatic fibrogenesis, stellate cells are activated leading to production and deposition of extracellular matrix. To clarify the role of PDGF-B in liver fibrogenesis, we overexpressed PDGF-B in the liver of transgenic mice. Methods Transgenic mice for the conditional overexpression of PDGF-B in the liver under control of an albumin promoter were generated utilising the Cre/loxP system. Constitutive PDGF-B expression was achieved after breeding with mice expressing Cre-recombinase under actin promoter control. Tamoxifen inducible expression was achieved after breeding with mice expressing Cre under transthyretin receptor promoter control. Levels of fibrosis were assessed an…
