Clostridium perfringens has been implicated in a broad array of enteric infections including the fatal haemorrhagic enteritis/enterotoxaemia syndrome in cattle. The beta2 toxin (CPB2), encoded by cpb2, is suspected to be implicated in this syndrome. However, among C. perfringens isolates from cattle suspected of clostridial disease, an atypical allele was recently found to predominate at the cpb2 locus and atypical corresponding CPB2 proteins were shown to be poorly expressed, thus arguing against a biologically significant role of the beta2 toxin in clostridial diseases in cattle. This study compared genotype and phenotype of the beta2 toxin between C. perfringens isolates from a group of healthy calves (n = 14, 87 isolates) and from a group of enterotoxaemic calves (n = 8,41 isolates). PCR results revealed the exclusive presence of the typical "consensus" cpb2 in the enterotoxaernic group. Western blot analysis demonstrated that the typical variant of CPB2 was often expressed in isolates from enterotoxaemic calves (43.9%) and infrequently in isolates from healthy cattle (6.9%). These data suggest that the typical variant of the CPB2 toxin may play a role in the pathogenesis of cattle enterotoxaemia. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

The gadolinium(III) complex with a new DOTA-based ligand bearing a methanethiosulfonate group (MTS) was synthesized and its relaxivity properties were investigated. MTS-ADO3A is a triacid DOTA derivative with an amide arm substituted by an ethylmethanethiosulfonate function. This ligand was obtained in two steps: tri-tert-butyl 2,2′,2″-(1,4,7,10-tetraazacyclododecane-1,4,7-triyl)triacetate was reacted with S-(2-aminoethyl)methanesulfonothioate and the tert-butyl groups were removed with trifluoroacetic acid. The Gd(III) MTS–ADO3A complex readily formed disulfide bonds with albumin (BSA) in its native and reduced forms and with thiolated silica particles. Four- to five-fold relaxivity increases at 20 MHz were measured on the isolated adducts. The EuMTS-ADO3A chelate was found to be monohydrated by fluorescence and the relaxivity parameters of the Gd(III) complex were obtained by 17O NMR and by measuring the nuclear magnetic relaxation dispersion between 0.01 and 80 MHz. The water exchange time τm is increased upon forming disulfide bonds with macromolecules and particles and the relaxivity gains of all the complexes are limited by the τm factor. Forming covalent or hydrophobic/electrostatic bonds with BSA seems to bring about similar relaxivity changes but the covalent BSA adducts can be isolated and their properties can be directly studied. The addition of dithiothreitol or glutathione leads to the removal of the metal chelates from the macromolecules, as indicated by the relaxation times reverting to their values before binding. It is thus expected that the chelate will stay in the body long enough for imaging but will still be excreted through the kidneys. [less ▲]

Invasive exotic plants can modify soil organic matter (SOM) dynamics and other soil properties. We evaluated changes in particulate organic matter (POM) and carbon (C) mineralisation in adjacent plots invaded by Solidago gigantea, Prunus serotina, Heracleum mantegazzianum and Fallopia japonica, and non-invaded control plots on different soils in Belgium. Litter decomposition of S. gigantea and P. serotina was compared to that of the native species Epilobium hirsutum, Betula pendula and Fagus sylvatica. Disregarding the differences in site characteristics (soil texture, parental material and plant species), we argued that the invasion by S. gigantea and P. serotina enhance SOM dynamics by increasing C mineralisation in 2 out of 3 sites invaded by S. gigantea and in 1 out of 3 sites invaded by P. serotina; C in coarse POM (cPOM, 4,000-250 mu m) and fine POM (fPOM, 250-50 mu m) in 1 site invaded by S. gigantea and C content in total POM (tPOM, 4,000-50 mu m) and the organo-mineral fraction (OMF, 0-50 mu m) in 1 site invaded by P. serotina. H. mantegazzianum and F. japonica slowed down SOM dynamics by reducing C mineralisation in three out of four sites; C and nitrogen (N) of fPOM in the invaded compared with the non-invaded plots at one site invaded by H. mantegazzianum. However, N content of cPOM (4,000-250 mu m) was higher in the invaded sites by F. japonica compared with the non-invaded plots. Our results indicated that the effects of invasion by exotic plant species were not species-specific but site-specific. [less ▲]

CONTEXT: Limited screening suggests that three germline mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene are not involved in sporadic pituitary tumorigenesis. Multiple novel mutations of this gene have since been identified in familial isolated pituitary adenoma cohorts. OBJECTIVE: The objective of the study was to undertake full AIP coding sequence screening to assess for the presence of germline and somatic mutations in European Union subjects with sporadic pituitary tumors. DESIGN: The study design was the analysis of DNA from peripheral blood lymphocytes and analysis of exons 1-6 and paraexonic intron sequences of AIP. Multiplex ligation-dependent probe amplification was used to screen separate sporadic pituitary tumor tissue samples for discrete and extensive deletions or mutations of the AIP gene. Setting: The study was conducted in university tertiary referral Clinical Genetics, Molecular Biology, and Endocrinology Departments. RESULTS: In 107 patients [prolactinomas (n =49), nonfunctioning tumors (n = 29), somatotropinomas (n = 26), ACTH-secreting tumors (n = 2), TSH-secreting tumors (n = 1)], no germline mutations of AIP were demonstrated. Among a group of 41 tumor samples from other subjects, a novel AIP mutation (R22X) was found in one sample in which the corresponding allele was deleted; follow-up screening of the patient demonstrated a germline R22X AIP mutation. CONCLUSIONS: AIP mutations do not appear to play a prominent role in sporadic pituitary tumorigenesis in this population of European subjects. [less ▲]

A la demande du Centre d’Aide aux Personnes Agées Maltraitées (CAPAM), le Département de Médecine Générale de l’Université de Liège a mené une recherche qualitative portant sur la maltraitance des aînés à domicile. Cette étude avait pour objectif d’analyser le ressenti, en matière de maltraitance des personnes âgées, de professionnels de la santé de trois disciplines intervenant fréquemment au domicile : médecins généralistes, aides familiales et infirmier(e)s. Pour chaque profession, une trentaine de représentants issus de pratiques variées (urbaines et rurales ; salariés et indépendants ; etc.) ont été sélectionnés et répartis en trois focus groups (groupes de discussion semi-structurés encadrés par un animateur) . La transcription intégrale du contenu des discussions a servi de base à l’analyse de contenu. Un guide d’entretien a été construit au départ des questions de recherche suivantes : Comment les professionnels de la santé concernés définissent-ils la maltraitance des personnes âgées ? Dans quel contexte la rencontrent-ils éventuellement ? Quels sont les signes qui peuvent leur faire suspecter cette maltraitance ? Quels rôles pensent-ils avoir et de quelle(s) manière(s) agissent-ils ? Quelles difficultés rencontrent-ils face à une situation de maltraitance à domicile ? Quels sont leurs besoins pour y faire face efficacement ? Quelles pistes d’action pourraient être apportées à cette problématique à un niveau sociétal ? [less ▲]

La morphologie des particules est une propriété essentielle pour comprendre et prédire leur rhéologie, leur agglomération, leur compaction et bien d'autres de leurs propriétés physiques. Suite à l'apparition de nouvelles techniques d'imagerie en trois dimensions adaptées aux matériaux, il est à présent possible d'étendre les descripteurs de forme existant en deux dimensions à la troisième. Deux échantillons de particules métalliques dont l'étendue granulaire est de 150-250 μm ont été selectionnés. Le choix de ces poudres est un véritable défi car la forme complexe des particules justifie l'élaboration de nouveaux descripteurs de taille et de forme. Cet article présentes les résultats de la caractérisation morphologique en trois dimensions de matériaux granulaires. L'acquisition d'images est pratiquée par microtomographie des rayons X permettant une résolution inférieure à 10 μm. Pour chaque particule, le volume, la surface, l'allongement, l'aplatissement, la convexité et le rayon de la sphère maximale inscrite sont calculés en trois dimensions. Les algorithmes écrits pour mesurer ces propriétés ont été validés sur des particules synthétiques. La réalisation d'une analyse morphologique complète de quelques milliers de particules permet d'appréhender les paramètres de forme de façon statistique. Finalement, les résultats seront confrontés à ceux obtenus par analyse d'image statique (SIA) en 2D. [less ▲]
