Glucansucrase or glucosyltransferase (GTF) enzymes of lactic acid bacteria display high sequence similarity but catalyze synthesis of different alpha-glucans (e.g., dextran, mutan, alternan, and reuteran) from sucrose. The variations in glucosidic linkage specificity observed in products of different glucansucrase enzymes appear to be based on relatively small differences in amino acid sequence...

BACKGROUND Amyloid A (AA) amyloidosis is a multisystem, progressive and fatal disease. Renal involvement occurs early in the course of AA. We aimed to investigate the etiology, clinical and laboratory features, and outcome of patients with biopsy-proven renal AA amyloidosis. MATERIALS AND METHODS A total of 121 patients (male/female: 84/37, mean age 42.6 ± 14.4 years) were analyzed retrospect...
12.1.2. Let M be a module over the integral domain R. (a) Assume that M has rank n and that x1, . . . , xn is any maximal set of linearly independent elements of M . Prove that N is isomorphic to Rn and that the quotient M/N is a torsion Rmodule. (b) Prove conversely that if M contains a submodule N that is free of rank n (i.e., N Rn) such that the quotient M/N is a torsion R-module then M ha...
Les tumeurs conjonctives cutanées sont des tumeurs dermiques et/ou hypodermiques relativement fréquentes. Elles sont dominées par les tumeurs bénignes. A travers une série de 121 cas, nous avons étudié le profil épidémiologique, anatomopathologique et évolutif de ces tumeurs. C'est une étude rétrospective réalisée au service d'anatomie pathologique du CHU Mohammed VI de Marrakech entre 2004 et ...

Lactobacillus reuteri strain 121 uses sucrose for synthesis of a unique, soluble glucan ('reuteran') with mainly alpha-(1-->4) glucosidic linkages. The gene (gtfA) encoding this glucansucrase enzyme had previously been characterized. Here, a detailed biochemical and molecular analysis of the GTFA enzyme is presented. This is believed to be the first report describing reuteransucrase enzyme kine...
The two most abundant secreted isoforms of vascular endothelial growth factor A (VEGF(165) and VEGF(121)) are formed as a result of differential splicing of the VEGF-A gene. VEGF(165) and VEGF(121) share similar affinities at the isolated VEGF receptor (VEGFR)-2 but have been previously demonstrated to have differential ability to activate VEGFR-2-mediated effects on endothelial cells. Herein w...
T cell clones recognizing the sperm whale myoglobin (SpWMb) epitope 110-121 in association with H-2d major histocompatibility complex class II molecules display a very limited heterogeneity of T cell receptor (TCR) VO usage in DBA/2 mice. All clones previously tested used the same V(3 8.2 gene segment and very restricted junctional regions. To investigate the significance of this observation in...
Our interests are in the development of immunoassay-based fast scanning methods for persistent organic pollutants. To develop the immunoassay method of polybrominated diphenyl ether (PBDE), a model compound of PBDE, 2,3',4,5',6-pentabromodiphenylether (BDE-121), has been chosen to develop its antibody and the competitive indirect enzyme-linked immunosorbent assay (ELISA) is developed. The hapte...
