Modification de la gestion du dialogue intérieur des sportifs de haut niveau. Etude préliminaire

Le dialogue intérieur est constitué de pensées qui sont généralement spontanées mais qui peuvent également être sous le contrôle direct du sportif. Selon Hatzigeorgiadis, Zourbanos, Galanis et Theodorakis (2011), le discours peut revêtir une orientation pédagogique ou motivante. Ces auteurs ont montré que les pensées motivantes sont plus efficaces pour améliorer la performance dans des situations nécessitant un effort de longue durée ou de la force. Par contre, le discours pédagogique est plus utile pour les tâches qui demandent du temps et/ou de la précision. Les pensées spontanées des sportifs sont à 80% négatives. Il est donc logique de tenter de modifier cette situation afin d’augmenter la part des pensées opérationnelles (objectif clair, énoncé bref et simple phonétiquement, initiation d’un acte ou un geste concret, stimulation). Dans cette étude, nous testons une approche visant justement à amener des sportifs à mieux exploiter leur dialogue intérieur. Notre étude porte sur 5 joueuses de volley-ball de 2ème nationale belge (postes de jeu différents) provenant de deux équipes, toutes volontaires. Nous avons filmé une première confrontation entre ces deux formations. Sur base de l’enregistrement vidéo, nous avons effectué des entretiens stimulés individuels ciblant divers événements survenus lors de la rencontre. Ces retours sur la pratique nous ont permis d’identifier les pensées des joueuses. Par la suite, chacune de celles-ci a participé à deux séminaires individuels qui avaient pour objectif de modifier les pensées négatives et positives en pensées opérationnelles. A l’issue du match retour, nous avons répété une séance de rappel stimulé et avons complété la collecte des données par un débriefing général. Parmi les résultats que nous avons déjà mis en évidence, nous retiendrons que le discours pédagogique s’avère particulièrement pauvre par rapport au discours motivant. Des implications pratiques sont proposées. [less ▲]

Modification of immunoreactive EGF receptor after acute tubular necrosis induced by tobramycin or cisplatin

Acute tubular necrosis induced by aminoglycoside antibiotics and various other nephrotoxins is followed by a regenerative process which leads to the restoration of damaged tubules. Several lines of evidence indicate that tubular regeneration is mediated by polypeptide growth factors such as epidermal growth factor (EGF). Previous studies devoted to cisplatin nephrotoxicity have shown that this agent causes tubular cystic degeneration possibly related to an impairment of renal tissue repair. Thus, we examined on a comparative basis the time course of the regenerative response subsequent to tubular damage induced by tobramycin or cisplatin, particular attention being paid to renal EGF and its receptor. Female Sprague-Dawley rats (160-180 g body weight) were treated during 4 consecutive days with daily doses of 200 mg/kg tobramycin i.p. (BID) or 2 mg/kg cisplatin (once a day). Sham-treated rats were given 0.9% NaCl i.p. following the same protocol. Groups of experimental animals (n = 5-10) were terminated at increasing time intervals (1, 4, 7, 14, 21, 60 days) after cessation of treatment. One hour prior to sacrifice, each individual received i.p. 200 mg/kg 5-bromo-2'-deoxyuridine (BrdU) for the immunohistochemical demonstration of cell proliferation. Blood was collected at the time of sacrifice in order to assess glomerular filtration rate by measuring serum creatinine and BUN levels. Kidneys were analyzed with respect to total EGF determined by RIA in renal tissue homogenates, and soluble EGF was assayed in extracts prepared by centrifugation. Renal tissue was processed for the immunohistochemical detection of S-phase cells, of EGF, of EGF receptors, and of the intermediate filament vimentin, the latter being used as a marker of epithelium dedifferentiation. In absence of nephrotoxic alterations, EGF was immunolocalized in distal tubules, whereas EGF receptor immunostaining was seen in proximal tubules cells. Vimentin immunostaining was confined to glomeruli and blood vessels. Tobramycin and cisplatin caused acute tubular necrosis in proximal convoluted tubules and proximal straight tubules, respectively. Tissue damage was accompanied by renal dysfunction reflected by an elevation of serum creatinine and BUN levels. Tubular necrosis was followed by a proliferative response indicative of tubular regeneration. Regenerative hyperplasia was associated with a reduction of total immunoreactive EGF due to a decrease of tissue-bound proEGF. Tubules undergoing regenerative repair were characterized by a disappearance of EGF receptors and the presence of immunoreactive vimentin. In tobramycin-treated rats, renal dysfunction lasted for 4-7 days and was fully reversible, as indicated by the return of serum markers to normal values. [less ▲]

Modification of the Selected Method for the Determination of Serum Iron. Substitution of Bathophenanthroline by Ferene S

The previously selected method (1977) for the measurement of iron in human serum has been modified by the working group on Iron and Iron-Transport Proteins (Societe Francaise de Biologie Clinique). Ferene S is used as the chromogen, it is more sensitive and cheaper than bathophenanthroline. The sample size has been reduced from 2 to 0.5 ml. No interference could be shown with high concentrations of bilirubin, copper or hemoglobin. [less ▲]

Modification of the Thermoresistance to Spray-Drying of a Cold-Adapted Subtilisin by Genetic Engineering

The thermoresistance of a cold-adapted subtilisin dried by spray-drying was studied. Proteolytic activity of this enzyme was measured before and after spray-drying. Without chemical additives, spray-drying yields ranged from 2-13%. The use of arabic gum and lactose in the composition of the enzyme solutions allowed the strengthening of the enzyme structures and increased water mobility in the product. Increase of water mobility led to a shorter residence time of the product in the spray-drier and a net yield increase was obtained (yield higher than 50%). The effect of two selective mutations on the thermoresistance to spray-drying of the cold-adapted subtilisin was also investigated. Mutation T85D (introduction of an additional link with an ion Ca2+ necessary for enzyme activity, by substitution of Asp for Thr 85) had no effect on the thermoresistance of the subtilisin to spray-drying. Mutation H121W (introduction of an additional aromatic link by substitution of Trp for His 121) reduced the drying yield from 66% (not modified subtilisin) to 52%. This higher thermosensitivity could be explained by an increase of the hygroscopic character of the modified subtilisin (mutation H121W). [less ▲]
