Cyclist Endofibrosis (Exercise-Induced Arterial Endofibrosis) Treated by Drug-Coated Balloon Angioplasty

Exercise-induced arterial endofibrosis is an uncommon entity that is most frequently identified in high-performance athletes, especially cyclists. We present this disease in a male professional cyclist of 22 years of age. The course of his condition, clinical manifestations, modalities of investigation, and a nonprecedent treatment plan are demonstrated

Ultrasound/Chlorine: A Novel Synergistic Sono-Hybrid Process for Allura Red AC Degradation

Herein, we present an original report on chlorine activation by ultrasound (US: 600 kHz, 120 W) for intensifying the sonochemical treatment of hazardous organic materials. The coupling of US/chlorine produced synergy via the involvement of reactive chlorine species (RCSs: Cl•, ClO• and Cl2•−), resulting from the sono-activation of chlorine. The degradation of Allura Red AC (ARAC) textile dye, as a contaminant model, was drastically improved by the US/chlorine process as compared to the separated techniques. A synergy index of 1.74 was obtained by the US/chlorine process for the degradation of ARAC (C0 = 5 mg·L−1) at pH 5.5 and [chlorine]0 = 250 mM. The synergistic index increased by up to 2.2 when chlorine concentration was 300 µM. Additionally, the synergetic effect was only obtained at pH 4–6, where HOCl is the sole chlorine species. Additionally, the effect of combining US and chlorine for ARAC degradation was additive for the argon atmosphere, synergistic for air and negative for N2. An air atmosphere could provide the best synergy as it generates a relatively moderate concentration of reactive species as compared to argon, which marginalizes radical–radical reactions compared to radical–organic ones. Finally, the US/chlorine process was more synergistic for low pollutant concentrations (C0 ≤ 10 mg·L−1); the coupling effect was additive for moderate concentrations (C0~20–30 mg·L−1) and negative for higher C0 (>30 mg·L−1). Consequently, the US/chlorine process was efficiently operable under typical water treatment conditions, although complete by-product analysis and toxicity assessment may still be necessary to establish process viability

33| N - Nektiberes

Naissance, Navigation, Nécropole, Nefoussa, Néolithisation, Nomadisme, Numides... Les fascicules XXXIII et XXXIV, lettre « N », viennent de paraître aux éditions Peeters. Composés de 82 notices rédigées par 43 auteurs distincts, les entrées couvrent, sur un total de 480 pages de texte, l'ensemble des sujets centraux de l’histoire et des sociétés berbères. On signalera notamment le très important dossier « Néolithisation–Néolithique » (9 notices = 80 pages), essentiel sur la question de la mise en place du peuplement berbère de l’Afrique du Nord ; mais aussi bien d’autres entrées centrales pour l’histoire des Berbères, notamment « Numidie » (40 p.). Aux sciences historiques font pendant nombre d’entrées ethnologiques, anthropologiques, linguistiques ou littéraires elles-aussi importantes : « Naissance » (3 notices), « Narration », « Nattes », « Nefoussa (Djebel) » (4 notices), « Négation », « Néologie », « Nom », « Nomadisme » (4 notices), « Numération »… qui illustrent bien le caractère profondément pluridisciplinaires de l’Encyclopédie berbère. On soulignera aussi le caractère fortement collaboratif de ces deux derniers fascicules : de nombreuses entrées ont été traitées et/ou écrites « à plusieurs mains » et ont fait l’objet d’intenses échanges entre les différents rédacteurs
