Ischaemia-reperfusion injury (IRI) is caused by endothelial and subendothelial damage by neutrophil-derived oxidants. Vitamin C is an antioxidant which attenuates endothelial injury after IRI. Our aim was to evaluate the effect of oral vitamin C in the prevention of IRI in skeletal muscle. We used a model of cross-clamping (3 hours) and reperfusion (1 hour) of the cremaster muscle in rats. Muscle function was assessed electrophysiologically by electrical field stimulation. Infiltration by neutrophils was determined by the activity of tissue myeloperoxidase (MPO) and tissue oedema by the wet-to-dry ratio. Neutrophil respiratory burst activity was measured in control animals and groups pretreated with vitamin C. IRI significantly decreased muscle function and increased muscle neutrophil MPO activity and muscle oedema. Pretreatment with vitamin C preserved muscle function and reduced tissue oedema and neutrophil infiltration. Neutrophil respiratory burst activity was reduced in the group treated with vitamin C compared with the control group. We conclude that pretreatment with oral vitamin C protects against acute muscle IRI, possibly by attenuating neutrophil respiratory burst activity. [less ▲]

Avant d’utiliser les scories métallurgiques comme traceur et indicateur de la compétence de l’Aisne à différents endroits de son cours, nous avons relevé les différents atouts qui ont favorisé le développement de la sidérurgie dans la « Terre de Durbuy » et nous avons étudié l’évolution des techniques sidérurgiques afin de mieux comprendre la genèse des scories. Dans cet article, nous étudions plus particulièrement l’évolution longitudinale de la taille des scories dans l’Aisne, entre Blier et Bomal où elle se jette dans l’Ourthe. Vu la trop grande proximité des sites de rejets, nous n’avons pu proposer qu’une vitesse minimum d’avancée de la charge de fond ; les scories prélevées nous ont cependant renseignés sur les variations de puissances spécifiques dans les différents tronçons de la rivière.

The adsorption behaviour of five different globular proteins on pure silicon substrates and on preadsorbed polyampholytic monolayers has been investigated as a function of protein concentration. The prelayers were prepared by adsorption of the ampholytic diblock copolymer poly(methacrylic acid)-block-poly ((dimethylamino)ethyl methacrylate) (PMAA-b-PDMAEMA). This polyampholyte adsorbs in densely packed micelles directly from aqueous solution. Ellipsometry was used to determine the amount of adsorbed polyampholyte and protein. While ATR-IR spectroscopy gives information about the adsorption and desorption behaviour of the preadsorbed polyampholytic layer, the lateral structures of the dried films were investigated by scanning force microscopy (SFM). The amount of protein adsorbed was found to be strongly influenced by the preadsorbed polyampholyte compared to the adsorption on the pure silicon substrates. No displacement of the polyampholyte by the proteins was detected. In most cases the protein adsorption was reduced by the preadsorbed polyampholytic layer. The observed trends are explained by the change in electrostatic and hydrophilic characteristics of the substrates. Furthermore, the entropy of adsorption has to be taken into account. [less ▲]

Amphiphilic copolymers consisting of an animated hydrophobic block and a hydrophilic poly(sodium methacrylate) one have been synthesized with different structures and tested as stabilizers for aqueous dispersions of alumina coated titanium dioxide (80 wt.-% solid). The dispersion stability is ruled by the strength of the anchoring of the aminated block onto the pigment and by the dynamics of the micelles formed by the copolymer. Any decrease in the anchoring strength, for example as a result of higher steric hindrance for the adsorbing block or of random rather than blocky distribution of the aminated co-units, is detrimental to the dispersion stability and makes this stability more dependent on the copolymer composition. Indeed, the position and dynamics of the unimers micelles equilibrium then control the adsorption of the copolymer on the pigment during the grinding process. [less ▲]

Autoimmune pancreatitis has been characterised in 1995, but only a few cases have been published since then, most of them from Japan. This report describes the cases of two Belgian male patients who presented with isolated obstructive jaundice. Radiological imaging studies were highly suggestive of carcinoma of the head of pancreas and both patients underwent uneventful cephalic pancreaticoduodenectomy with portal vein resection. Pathological analysis of the removed tissues suggested an autoimmune process in both cases. Both patients had hyper-gammaglobulinemia and antinuclear antibodies, but failed to show evidence of any other autoimmune disease or cause of chronic pancreatitis. In both cases final diagnosis was autoimmune pancreatitis. Preoperative clinical suspicion of this diagnosis is mandatory and may avoid unnecessary surgery in future cases. [less ▲]

In Posidonia oceanica (L.) Delile, anthesis induces a decrease in the number of juvenile leaves resulting in a significant reduction in the number of leaves on the flowering shoots. All the leaves of the flowering shoots are narrower than the leaves of nonflowering shoots. A modification of the leaf growth also appears in flowering shoots: the oldest leaves are longer and the leaves induced during or after anthesis are shorter. At 10 m depth, in the Bay of Calvi, anthesis lasts roughly 3 months and the flowering is induced 7 months before anthesis. [less ▲]

This article presents the training objectives (motivational, metacognitive, instrumental, and disciplinary) of a pedagogical method known as PARMs (multimedia reciprocal animation project) and procedures for self-observation of learning as experienced by university students. The authors describe a series of didactic-mathetic activities related to training objectives, as well as those learning strategies promoted in the PARMs course. Two instruments to measure metacognitive thinking are presented: « Questionnaire on progress » and « Questionnaire on mathetical self-description ». The results of these questionnaires is then discussed. [less ▲]

Cet article traite des liens entre la mobilité quotidienne et les évolutions intra-urbaines. Dans ce cadre, un espace géographique urbain de référence a tout d'abord été construit ; afin de clarifier des processus d'évolution, il semble en effet naturel de débuter par la définition d'un état stable. Concernant les processus, plusieurs différenciations ont été opérées, notamment : l'urbanisation par rapport à la désurbanisation et l'urbanisation fonctionnelle par rapport à l'urbanisation morphologique. La problématique des types de mobilité a également été intégrée, ce qui a déterminé une réflexion sur le thème de la transition périurbaine, c'est-à-dire le processus de mutation de la ville sous l'impact de la mobilité automobile.
