Inflammatory Murine Skin Responses to UV-B Light Are Partially Dependent on Endothelin-1 and Mast Cells

2006

Endothelin (ET-1) has been shown to crucially contribute to UV-induced skin responses such as tanning. To test whether ET-1 is also involved in early cutaneous reactions to UV, we assessed ET-1 skin levels in UV-irradiated mice. In correlation with the levels of UV-induced skin inflammation, ET-1 concentrations increased substantially and continually. Moreover, blocking of ET-1 receptors (ET A ) resulted in significantly decreased cutaneous inflammation following UV irradiation. When we assessed skin responses to ET-1 injections, we observed prominent mast cell degranulation and mast cell-dependent inflammation. Since mast cells also critically contributed to UV-induced inflammation, we det…

Intravenous BQ-123 and phosphoramidon reduce ventricular ectopic beats and myocardial infarct size in dogs submitted to coronary occlusion and reperf…

2001

Abstract The aim of this work was to investigate the influence of endothelin on myocardial ischemia and reperfusion in anaesthetized dogs. Animals were submitted to left thoracotomy and 120 min of left anterior descending coronary occlusion, followed by 180 min of reperfusion. Arterial blood pressure and electrocardiogram (ECG) were recorded in order to analyze heart rate (HR)–pressure product and production of ectopic beats. Infarcted areas were identified by a macroscopic staining method and infarct size was expressed as percentage of risk zone. To inhibit the effects of endothelin in a group of animals, we administered intravenously an endothelin synthesis inhibitor (phosphoramidon) and …

Anti-inflammatory properties of simvastatin on leukocyte-endothelial cell interactions following hemorrhagic shock

2002

Background Hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) have been shown to lower serum cholesterol levels. Recent studies reported that statins have vasculoprotective effects independent of their cholesterol-lowering properties. We studied simvastatin for its ability to modulate leukocyte-endothelial cell interactions under acute inflammation following hemorrhage and reperfusion. Methods The effects of simvastatin on leukocyte-endothelial cell interactions were observed by intravital microscopy in the rat mesenteric microcirculation and by immunohistochemical analyzes. Simvastatin (50 μg/kg or 100 μg/kg) was administrated intraperitoneally 18 h before study. Inf…

L'influence des évènements familiaux dans la formation des revenus

1985

Référence interne : 85013; En décomposant l'expérience professionnelle des hommes et des femmes en fonction d'évènements familiaux marquants, l'objectif est de mesurer l'effet du mariage sur les gains, et de mettre en relation le bénéfice de l'union avec le niveau d'éducation de l'individu. L'approche suivie analyse également le role de la fécondité, en particularisant l'effet de l'espacement des naissances et de l'âge à la première naissance sur les profils de salaires.

Participer pour rendre le travail possible. Les staffs en unités de soins palliatifs

2018

Répondant à un mandat médical particulier — soigner sans guérir —, les professionnels de soins palliatifs font d’une partie du « sale boulot » hospitalier leur cœur de métier. Dans l’incapacité d’y faire face seuls mais aussi pour lutter contre la souffrance au travail, les médecins attendent des personnels paramédicaux qu’ils participent à l’élaboration du soin à travers des réunions pluridisciplinaires nommées « staff ». Cette participation modifie la division du travail habituellement en vigueur à l’hôpital, et entraîne des « charges de la participation » supplémentaires pour les paramédicaux. Mais dans le même temps, les staffs permettent aux paramédicaux de s’approprier les cadres cult…

Sustainability for 3DP Operations

2020

Sustainability is an essential consideration in manufacturing, and within this chapter a detailed appraisal is given to sustainability for 3D printing. An in-depth review of existing research is provided, and a cradle-to-grave assessment technique is shown to assess the environmental impact of 3D printed part.

Integrated three-dimensional models for noninvasive monitoring and valorization of the Morgantina silver treasure (Sicily)

2016

The Morgantina silver treasure belonging to the Archaeological Museum of Aidone (Sicily) was involved in a three-dimensional (3-D) survey and diagnostics campaign for monitoring the collection over time in anticipation of their temporary transfer to the Metropolitan Museum of Art in New York for a period of 4 years. Using a multidisciplinary approach, a scientific and methodological protocol based on noninvasive techniques to achieve a complete and integrated knowledge of the precious items and their conservation state, as well as to increase their valorization, has been developed. All acquired data, i.e., 3-D models, ultraviolet fluorescence, x-ray images, and chemical information, will be…
