A partir des protéines et de l'ADN extraits des feuilles de Moricandia arvensis, collectées de quatre régions du sud tunisien, nous avons étudié la variabilité de cette plante reconnue pour ses vertus médicinales. Nous avons analysé d’une part les protéines totales extraites puis séparées par la technique SDS-PAGE. Cette méthode a révélé un degré de similitude très remarquable entre les plantes issues des quatre régions et qui varie entre 0.77 et 0.91. Nous avons effectué d’autre part, une analyse de la variabilité génétique par l’amplification aléatoire de l'ADN polymorphe par la technique PCR-RAPD en utilisant trois amorces différentes. Nous avons remarqué que la similitude est plus accentuée entre les plantes collectées des régions du Sud Ouest, avec un degré de similitude pouvant atteindre 100%. Celles issues du Sud Est présentent un degré de similitude de 66%. [less ▲]

BACKGROUND: The purpose of this prospective study was to assess whether neurodevelopmental status and exercise capacity of children 5 to 10 years after corrective surgery for tetralogy of Fallot or ventricular septal defect in infancy was different compared with normal children and influenced by the preoperative condition of hypoxemia or cardiac insufficiency. METHODS: Forty unselected children, 20 with tetralogy of Fallot and hypoxemia and 20 with ventricular septal defect and cardiac insufficiency, operated on with combined deep hypothermic circulatory arrest and low flow cardiopulmonary bypass at a mean age of 0.7 +/- 0.3 years (mean +/- SD), underwent, at mean age 7.4 +/- 1.6 years, standardized evaluation of neurologic status, gross motor function, intelligence, academic achievement, language, and exercise capacity. Results were compared between the groups and related to preoperative, perioperative, and postoperative status and management. RESULTS: Rate of mild neurologic dysfunction was increased compared with normal children, but not different between the groups. Exercise capacity and socioeconomic status were not different compared with normal children and between the groups. Compared with the normal population, motor function, formal intelligence, academic achievement, and expressive and receptive language were significantly reduced (p < 0.01 to p < 0.001) in the whole group and in the subgroups, except for normal intelligence in ventricular septal defect patients. Motor dysfunction was significantly higher in the Fallot group compared with the ventricular septal defect group (p < 0.01) and correlated with neurologic dysfunction, lower intelligence, and reduced expressive language (p < 0.05 each). Reduced New York Heart Association functional class was correlated with lower exercise capacity and longer duration of cardiopulmonary bypass (p < 0.05 each). Reduced socioeconomic status significantly influenced dysfunction in formal intelligence (p < 0.01) and academic achievement (p < 0.05). Preoperative risk factors such as prenatal hypoxia, perinatal asphyxia, and preterm birth, factors of perioperative management such as cardiac arrest, lowest nasopharyngeal temperature, and age at surgery, and postoperative risk factors as postoperative cardiocirculatory insufficiency and duration of mechanical ventilation were not different between the groups and had no influence on outcome. Degree of hypoxemia in Fallot patients and degree of cardiac insufficiency in ventricular septal defect patients did not influence the outcome within the subgroups. CONCLUSIONS: Children with preoperative hypoxemia in infancy are at higher risk for motor dysfunction than children with cardiac insufficiency. Corrective surgery in infancy for tetralogy of Fallot or ventricular septal defect with combined circulatory arrest and low flow bypass is associated with reduced neurodevelopmental outcome, but not with reduced exercise capacity in childhood. In our experience, the general risk of long-term neurodevelopmental impairment is related to unfavorable effects of the global perioperative management. Socioeconomic status influences cognitive capabilities. [less ▲]

Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS). Four different cementitious materials were synthesised: PC, AAS, GP, and a mix GP-AAS and fully compared about their compositions and (micro)-structures. X-ray diffraction has revealed the presence of semi-crystalline C-S-H gel binding phase in PC while AAS, GP and GP-AAS are nearly amorphous. Progressive structural changes have been observed between the different samples by means of infrared spectroscopy, Si-29 and At-27 magic-angle-spinning nuclear magnetic resonance spectroscopy: there is a polymerisation extent of the (alumino)-silicate framework from PC [SiQ(1) and SiQ(2) units] to AAS [SiQ(2) and SiQ(2)(1Al) units] and finally to GP [SiQ(4)(2Al) and SiQ(4)(3Al) units]. Scanning electron microscopy has shown that GP is a homogeneous matrix while the other materials are composites containing GGBFS grains surrounded by a binding matrix. Energy dispersive X-ray EDX analyses (line scans) have shown the absence of formation of any specific phase at the matrix-grains interfaces. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

The chemical compound Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O was synthesized with a Tuttle pressure vessel at 800 degrees C and 1 kbar during experimental investigations on the conditions of fillowite formation. The crystal structure of a single-crystal, space group R (No. 148), a = 15.2741(9), c = 43.334(3) angstrom, Z = 6, was determined from X-ray intensity data and refined up to R-1 = 0.0728 and R-l{FO > 4 sigma(FO)} = 0.0546. The crystal structure of Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O is similar to the structure of fillowite, Na6Ca3(Mn,Fe)(21)(PO4)(18.), but a significant difference between the synthetic H2O containing compound and fillowite is the replacement of (Na12)O-8(-) by Mn(H2O)(2)O-5(-) polyhedra, which form characteristic six-member rings. The coordination polyhedra around Na12 and Mn12 are so different that simple isomorphous substitution of Na12 by Mn12 is very unlikely, but whole six-member rings either of (Na12)O-8(-) or (Mn12)(H2O)(2)O-5 polyhedra seem to be distributed statistically over the crystal structure. No indication for ordering, e.g. sheet by sheet, has been observed. Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O is the first fillowite-like compound for which water is located in the structure from single-crystal study. This result is proved by infrared spectral data and indicates that water can play an essential role in the fillowite structure-type. Structural features of the synthetic compounds Na(Na,Mn)(7)Mn-22(PO4)(18)center dot 0.5H(2)O, Na4Ca4Mg21(PO4)(18) and fillowite are compared. [less ▲]

We consider the problem of regulating a monopolist with unknown costs when the regulator has limited funds. The optimal regulatory mechanism sat- isfies four properties. The first property is bunching at the top, that is the more efficient types produce the same quantity irrespective of their costs. The second property is separability of less efficient types. The third property is full bunching of types when the available fund is small enough. The fourth property of the mecha- nism is that it is a third best one, that is, the output under this regulatory mechanism is strictly lower than the second best output for any given type. [less ▲]

A cheilitis is an inflammatory disease confined to the lips. Several origins are recognized. Their nature is often different in children and adults. Some are spongiotic due to irritation or allergic reaction. Other lesions are keratotic and can evolve to leucoplasia and epidermoid carcinoma. [less ▲]
