Les conditions de détention dans le milieu carcéral belge sont-elles conformes au droit à la dignité humaine ? Hébergement, fouilles corporelles et isolement cellulaire

Dans le contexte de surpopulation carcérale qui touche bon nombre d'établissements pénitentiaires de notre pays, le droit à la dignité humaine trouve-t-il sa place ? C'est à travers trois problématiques que ce mémoire tente de répondre à cette question : l'hébergement, les fouilles corporelles et l'isolement cellulaire des détenus. En confrontant les normes supranationales à la loi belge, certaines avancées doivent être reconnues mais aussi un certain nombre de lacunes...Master [120] en droit, Université catholique de Louvain, 201

Enzymatically prepared n-alkyl esters of glucuronic acid: The effect of hydrophobic chain length on surface properties

The effect of hydrophobic chain length on surface properties of enzymatically prepared n-alkyl esters of glucuronic acid are examined. Dynamic parameters from Hua and Rosen's mathematical model and equilibrium surface tension are presented for esters with octyl, decyl, dodecyl, and tetradecyl alkyl segments. Increasing the alkyl chain length has a significant influence on the surface activity. Decyl and dodecyl glucuronate exhibit an interesting adsorption speed associated with foaming capacity. Octyl glucuronate exhibits a micellar organization as its bulk concentration is over 10.68 mM. (C) 2002 Elsevier Science (USA)

Spontaneous and Drug-induced Arteritis/Polyarteritis in the Göttingen Minipig—Review

Arteritis/polyarteritis occurs spontaneously in many species used in preclinical toxicology studies. In Göttingen minipigs, arteritis/polyarteritis is an occasionally observed background change. In the minipig, this finding differs in frequency and nature from age-related polyarteritis nodosa in rats or monkeys, and Beagle pain syndrome in dogs. In minipigs, it can be present in a single small- or medium-sized artery of an organ or a few organs and is most commonly recorded in the cardiac and extracardiac blood vessels, vagina, oviduct, rectum, epididymis, spinal cord, pancreas, urinary bladder, kidneys, and stomach. The etiology is unknown although it has been considered in minipigs as well as in rats, dogs, and monkeys to be possibly immune mediated. This background change is important with respect to its nature and distribution in the minipig in order to distinguish it from drug-induced vascular changes, which might occur in similar locations and have similar morphologic features. This review summarizes the morphology, incidence, and predilection sites of arteritis as a spontaneously occurring background change and as a drug-induced vasculopathy in the minipig, and also describes the main aspects to consider when evaluating vascular changes in Göttingen minipig toxicity studies and their human relevance

Les esters de sucres : voies de synthèse et potentialités d'utilisation

Sugar esters : ways of synthesis and potential applications [a review]. Sugar esters are nonionic surfactants and exhibit relevant properties as structural diversity and environmental and health safety. Their potential applications extend from human food to drugs formulation and biochemical studies. Some sugar esters also exhibit interesting biological activities. A lot of papers have been submitted during the last ten years. Those articles describe the various ways of synthesis of those compounds at the laboratory scale. During the last ten years, the most studied method was the biotechnological way using enzyme as a catalyser

Sugar esters: ways of synthesis and potential applications.

Sugar esters are nonionic surfactants and exhibit relevant properties such as structural diversity and environmental and health safety. Their potential applications extend from human food to drug formulations and biochemical studies. Some sugar esters also exhibit interesting biological activities. Many papers on the subject have been submitted during the last 10 years. Those articles describe the various ways of synthesis of those compounds at the laboratory scale. During the last 10 years, the most studied method was the biotechnological one using catalysis by enzymes. Available knowledge on these molecules is reviewed
