STUDY DESIGN: This is a report of a case. OBJECTIVE: To document the clinical, radiographic, and histologic characteristics of a lumbar extraforaminal juxtafacet cyst. SUMMARY OF BACKGROUND DATA: Spinal juxtafacet cysts develop most frequently at the dorsal aspect of the zygapophysial joint, sometimes in the posterolateral area of the canal. In one case, they have been described in the foraminal and extraforaminal region. METHODS: Description of the case report. RESULT: The authors report one case of a strictly extraforaminal juxtafacet cyst responsible for L5 sciatica. CONCLUSIONS: Juxtafacet cysts of the spine represent an infrequent cause of sciatica, usually when they grow in the canal, or more exceptionally when they occupy the foraminal or extraforaminal areas.

The goal of this study was to explore in patients with Alzheimer's disease (AD) the brain correlates of free and cued recall performance using an adaptation of the procedure developed by Grober and Buschke (1987). This procedure, which ensures semantic processing and coordinates encoding and retrieval, has been shown to be very sensitive to an early diagnosis of AD. Statistical parametric mapping (SPM 99) was used to establish clinicometabolic correlations between performance at free and cued verbal recall and resting brain metabolism in 31 patients with AD. Results showed that patient's score on free recall correlated with metabolic activity in right frontal regions (BA 10 and BA 45), suggesting that performance reflected a strategic retrieval attempt. Poor retrieval performance was tentatively attributed to a loss of functional correlation between frontal and medial temporal regions in patients with AD compared with elderly controls. Performance on cued recall was correlated to residual metabolic activity in bilateral parahippocampal regions (BA 36), suggesting that performance reflected retrieval of semantic associations, without recollection in AD. In conclusion, this study demonstrates that the diagnostic sensitivity for Alzheimer's disease of the cued recall performance in the Grober and Buschke procedure (1987) depends on the activity of parahippocampal regions, one of the earliest targets of the disease. Moreover, the results suggest that the poor performance of patients with AD during free and cued recall is related to a decreased connectivity between parahippocampal regions and frontal areas.

Le principal objectif visé par le présent travail est de mettre au point des catayseurs efficaces, capables de polymériser par voir radicalaire contrôlée des oléfines internes (peu réactionnelles) et, plus particulièrement, l'huile de lin.Nous tenterons aussi d'aborder la copolymérisation de l'huile de lin avec des monomères de grande consommation (styrène et (méth)acrylates) afin de mettre au point, au départ d'un produit naturel et renouvelable, des matériaux nouveaux. L'huile de lin est constituée d'un mélange complexe de triglycérides dont les chaînes pendantes sont porteuses de 2 ou 3 liaisons C=C doubles. Face à la diversité et à la complexité structurale de ces molécules, il nous parait évident d'aborder le problème de manière plus systématique en nous basant sur l'étude de la polymérisation d'oléfines internes et/ou fonctionnalisées qui serviront de "modèles" pour celles rencontrées dans l'huile de lin. Nous sommes en effet convaincus que la réussite de ce projet passe avant tout par une bonne compréhension des facteurs qui gouvernent la réactivité des oléfines internes et fonctionnalisées. Ce projet est réalisé dans le Laboratoire de Chimie Macromoléculaire et de Catalyse Organique (CERM) de l'Université de Liège en partenariat avec l'Institut des Sciences de Matériaux (ICMAB, Barcelone) et la Société Vandeputte (Belgique [less ▲]

Charts of sea level anomalies (SLA) based on the combined altimetry data from the TOPEX/POSEIDON and ERS-2 satellites, as well as the corresponding charts of the sea surface dynamic heights (constructed by the superposition of SLA distributions over the climatic dynamic topography) and the temperature gradients at the ocean surface on the basis of the satellite Multi-Channel Sea Surface Temperature (MCSST) data, were used to study the mesoscale variability related to the fronts in the Southern Indian Ocean (30degrees-60degrees S, 20degrees-150degrees E). An analysis of these three types of satellite information for the central weeks of each month during the period from 1997 to 1999 allowed us to distinguish zones of enhanced meandering (eddy formation) within the basin under study, as well as the contributions of individual fronts and their interaction to the regional mesoscale variability. The problems of the correlation between the intensity of mesoscale variability and peculiarities of the local bottom topography and seasonal/interannual variability of mesoscale dynamics are addressed.

Escherichia coli bacterial species is subdivided into several strains that are pathogenic for man and animals, on the basis of their specific properties and factors which are responsible for their pathogenic characters. The pathogenic strains are classically subdivided into strains with intestinal tropism (enterotoxigenic, enteropathogenic, enterohaemmorrhagic, verotoxigenic and enteroinvasive) and with extraintestinal tropism (uropathogenic and invasive). Invasive strains cause septicaemia and/or bacteraemia with localisations in different internal organs (systemic infections). If specific virulence properties and factors of strains with intestinal tropism are quite well known and described, those of strains with extraintestinal tropism are much less characterised, especially in animals. The purpose of this serie of review articles is to present the current knowledge on specific properties and factors of extraintestinal strains: adhesins and colonisation factors, transmucosal transfer and survival in blood and internal organs, toxicity. The fourth manuscript will deal with the invasive strains themselves, focusing on the necrotoxigenic strains. This third manuscript presents the current knowledge on toxins produced by invasive strains of E. coli: endotoxins, cytotoxic necrotising factors, cytolethal distending toxins and haemolytic toxins.

Sr and Nd isotopic data from the anorthosite-mangerite-charnockite (AMC) suite of the Late-Sveconorwegian (ca. 0.93 Ga) Rogaland anorthosite province of SW Norway are discussed. The study focuses on new data obtained from three distinct rock occurrences: (1) primitive (=MgO-rich and K2O-poor)jotunites that represent the parental magmas of leuconorite and mafic plutons (Sr-87/Sr-86(0.93Ga) = ca. 0.704-0.707, epsilon(Nd)(0.93 Ga) = +3.6 down to +1.2); (2) evolved jotunites that differentiated from the primitive jotunites and constitute the starting components of dyke-scale fractionation trends (Sr-87/Sr-86(0.93Ga) = ca. 0.705-0.713, epsilon(Nd)(0.93 Ga) = +0.4 down to -2.0); and (3) felsic plutons (Sr-87/Sr-86(0.93Ga) = ca. 0.707-0.723, epsilon(Nd)(0.93Ga) = +1.4 down to -1.7). A comparison of the Sr and Nd isotopic compositions with available geochemical data (major and trace elements) is also made. Fractionation of the primitive to the evolved jotunites, below the intrusion level of the anorthosite province, is shown to have involved crustal contamination. A case of fractional crystallization and simultaneous contamination/assimilation is substantiated in the felsic cap of a layered intrusion (the Bjerkreim-Sokndal intrusion). It is further proposed that the Sr and Nd isotopic compositions of the various felsic occurrences result from fractional crystallization of primitive jotunitic melts, with or without contamination/assimilation; this strengthens the possibility for large volumes of silica-rich magmas to have been produced by fractionation, through evolved jotunites, of primitive jotunites. The entire range in Sr and Nd isotopic compositions of the Rogaland anorthosite province is interpreted as reflecting a mixing of crustal contaminants, having variable Sr-87/Sr-86(0.93Ga) ratios and (negative) epsilon(Nd)(0.93 Ga) values, with a more isotopically primitive source. The crustal end members of that mixing array are represented by moderatey to strongly LILE-enriched high-grade gneisses from the Pre-Sveconorwegian basement of southernmost Norway, that have a crustal history extending back to 1.5-1.9 Ga in the surroundings of the anorthosite province. The primitive end member is either an unusual LREE-depleted and Rb-enriched component, possibly corresponding to an originally depleted source subsequently modified by metasomatic fluids, or a more classical depleted component; it corresponds to a gabbronoritic rock of the deep crust, as shown by recent experimental data, with a quite short crustal residence time (<0.4-0.2 Ga). If that mafic end member is the lower granulitic crust itself, this would imply the presence in the deep continental crust of southwesternmost Norway of a crustal material strongly different from the 1.7- to 1.9-Gyr-old, moderately LILE-enriched component that is supposed to constitute the largest volume of the present deep continental crust in southern Norway.
