Interleukin-1 beta (IL-1beta) is an important regulator of the thyroid cell function. This cytokine has been largely described to trigger an important biological signaling cascade: the sphingomyelin/ceramide pathway. In this report, we show that IL-1beta induces the transient activation of a neutral sphingomyelinase in porcine thyroid cells. Moreover,(More)
Two cases of adult respiratory distress syndrome were treated in a series of 26 patients suffering from colchicine overdose. The syndrome appeared between the 24th and 72nd hours. It was characterized by the presence of interstitial as well as alveolar oedema seen on chest roentgenograms. Haemodynamic investigation showed a hyperkinetic state with moderate(More)
Thrombospondins belong to a family of extracellular matrix (ECM) proteins widely found from embryonic to adult tissues. The modular structure of thrombospondins contains a series of peptide sequences implicated in a multiplicity of biological functions. Extracellular matrix undergoes important alterations under proteolysis that occurs in pathological(More)
Understanding the impact of noise on marine fauna at the population level requires knowledge about the vulnerability of different life-stages. Here we provide the first evidence that noise exposure during larval development produces body malformations in marine invertebrates. Scallop larvae exposed to playbacks of seismic pulses showed significant(More)
Metabisulfite intolerance is encountered in 8 p. 100 of cases of extrinsic asthma and in 20 p. 100 of cases of the "aspirin triad" with nasosinusal polyposis, asthma and aspirin sensitivity. The possibility that anaphylactoid shock or acute severe asthma leading to status asthmaticus, might be related to sulfite sensitivity must be well known. Two case(More)
In an attempt to elucidate the origin of the so-called idiopathic spontaneous pneumothorax (ISP), clinical examination, pulmonary function tests, and computed tomography (CT) with visual quantification and density analysis were performed in 20 young patients two months after an ISP episode. Twenty controls were recruited for CT. The chest roentgenograms(More)
Histopathological study of the liver has been undertaken on twenty-one diabetics with hyperlactatemia exceeding 5 mEq/1 of whom seven were treated with phenformin, six with metformin and eight not biguanide-treated. Hyperlactatemia occurred during the course or during resolution of severe ketoacidosis or of hyperosmolar coma. Hepatic lesions were invariably(More)
