BACKGROUND: Regular physical activity is an important health factor, but intense physical stress can increase the risk of heart disease. OBJECTIVE: Our aim was to determine the potential cardiac repercussions of, and the oxidative stress resulting from a maximal eccentric isokinetic exercise and a 1-hour treadmill run at 75% ˙V O2 max (maximal exercise done 6 weeks before). METHODS: Twelve young sedentary healthy subjects randomly performed two tests separated by 6 weeks: 1) 3 sets of 30 maximal eccentric isokinetic contractions of the quadriceps; 2) a 1-hour running on treadmill at 75% ˙V O2 max. We drew blood samples just before each exercise (T1), and just after (T2), 3 hours after (T3), and 24 hours after (T4) the end of each exercise to measure cardiac and oxidative stress biomarkers. RESULTS: In the running group, we observed significant differences for myoglobin (T3: 145 ± 80 μg/L), creatinine kinase (T4: 593 ± 350 mg/L), oxidized glutathione (T2: 22 ± 15.6 μmol/L), and highly sensitive cardiac troponin T, (T3: 0.051 ± 0.038 ng/mL). In the isokinetic group, we observed significant differences for myoglobin (T3:1419 ± 2533 mg/L), creatine kinase (3303 ± 7159 mg/L), and oxidized glutathione (T4:24 ± 14 μmol/L). Between isokinetic exercise and running, we observed significant differences for uric acid (p < 0.05, running > eccentric), myoglobin (p < 0.05, ditto), NT-proBNP (p < 0.05, ditto), hsTnT (p < 0.01, ditto), and oxidized glutathione (p < 0.05). CONCLUSIONS: As cardiac biomarkers appear practically unmodified after the isokinetic exercise, despite the considerable oxidative stress, we suggest that the application of intense maximal eccentric isokinetic exercise, when indicated, should be safe for most patients including those whose cardiac status is unknown. On the other hand, the increase in cardiac biomarkers observed after running, could reflect leakage of these biomarkers from the cytosolic pool of cardiac cells, linked to membrane damage, rather than the result of a major injury and hence running is supposed to be a safe practice. However, since sudden death during running has been previously described, assesment of the cardiac biomarkers and a follow-up by a sport doctor is important especially if there is a cardiac family history.

This article is about visual devices that in history of art and in semiotics are generally called "metavisual" and that are used to study some phenomena of framing in artistic images (see the works of Victor Stoichita and of Jean-François Bordron). We are going to explore the possibility to use these devices to analyse contemporary scientific images, trying to identify some common actions that go beyond the differences in terms of objects and economy of values between arts and sciences.

First in the USA and then in many other countries, scholarship on environmental inequality has sought to shed light on the unequal environmental conditions borne by poor people and ethnic minorities, and to challenge public policies and their unjust impacts on those target groups. Housing quality, especially the indoor characteristics of homes, offers an innovative perspective in this field of research. In previous research on environmental inequality in the Walloon context, housing quality has been proven to be a major determinant of quality of life and environmental well-being. This paper analyses housing quality through a twofold approach: through indoor characteristics on the one hand, and outdoor subjective and objective externalities on the other. It reveals the disparities between the most deprived and the wealthiest segments of the population. The evidence for this study is based on a housing quality survey carried out in 2012 and 2013 on 6,018 households in Wallonia (Belgium). The key findings are that poor people are found to live in housing of lower quality, in densely populated neighbourhoods and those with mixed use, with compensating amenities provided at the local level. Moreover, consistent with environmental inequality scholarship, deprived households are found to bear the burden of environmental degradation outside the home. People live in areas with poorer air quality, but are found to benefit from greater access to green spaces. The results of the survey reveal an interesting point concerning the environmental inequality literature; the interior features of housing are found to differ more widely between deprived and wealthier people than the surrounding environment does.

Cet article aborde les relations entre sémiotique et philosophie latourienne à partir de la théorie de l’énonciation, cette dernière se situant tant aux fondements du projet disciplinaire de la sémiotique francophone contemporaine qu’à la base de la réflexion de Bruno Latour, des années 1970 jusqu’à présent . Notre propos se déploie en deux moments : dans un premier temps, nous revenons sur l’article "Petite Philosophie de l’énonciation" (1998), et nous en suivons le développement dans l’Enquête sur les modes d’existence (2012). Dans un second temps, nous réalisons une rapide archéologie de la théorie de l’énonciation dans la sémiotique contemporaine, afin de mettre en lumière les liens entre différentes traditions sémiotiques et la théorie latourienne. Plus précisément, nous nous attachons aux propositions récentes de Jacques Fontanille et de Claudio Paolucci, en prenant également en considération les contributions d’Umberto Eco et Patrizia Violi. Il s’agit de voir comment les sémioticiens peuvent tirer profit de la théorie latourienne des modes d’existence et vice versa. [less ▲]

In this article we deal with questions related to images (painting, photography, digital image) from a semiotic standpoint, more precisely the form and substance of their expression plane. Classical greimasian semiotics –mainly through the works of Jean-Marie Floch (1985, 1986) and Félix Thürlemann (1982) – has concentrated on the relation between form of expression and form of content (thus in a semi-symbolic fashion). Then, in the 1990s, Jacques Fontanille started exploring the substance of expression. Later, within the framework of hierarchical levels of analysis, Fontanille (2005, 2008), introduced concepts such as material and formal support in order to distinguish between image as object and image as text. We take into account these works to study the close relationship between the substance of expression of images and the practices of production-reception. [less ▲]

Ce travail entend examiner les rapports entre les représentations photographiques des corps des scientifiques dans la revue de vulgarisation savante La Recherche, tels les portraits, les scènes de travail collectif en laboratoire etc., et les conceptions de la science qui en sont valorisées. L’étude des relations entre les photographies et les textes qui les accompagnent ont ainsi pour objectif de déployer une réflexion non seulement sur les différents types de commensurabilité entre le langage verbal et le langage visuel mais aussi sur le fait que le langage visuel est à même de forger de manière tout à fait autonome des valeurs identitaires et des formes de vie identifiables via l’analyse sémiotique. Notre exploration se développera en deux volets : le premier vise à esquisser la méthodologie de la sémiotique visuelle pour pouvoir introduire les niveaux pertinents de l’analyse sémiotique, le deuxième consiste à analyser un corpus constitué de textes tirés de quelques numéros de la revue La Recherche en en distinguant les différents genres discursifs (entretien, présentation de travaux en cours, etc.) et les différents types de cadrage et de mise en scène photographique afin d’expliquer comment ils se combinent avec les prises de position épistémologiques valorisées.
