Hypertension in subjects on long terme dialysis is frequent. Its origins are found in extracellular volume overload, which is complicated by increased peripheral arterial resistance. The latter is affected by many systems, including that of renin-angiotensin, between these factors may explain why the control of hypertension in dialysis patients requires ongoing attention to the many aspects of good dialysis.

BACKGROUND: We investigated the feeding ecology and habitat use of 32 harbour porpoises by-caught in 4 localities along the Scandinavian coast from the North Sea to the Barents Sea using time-integrative markers: stable isotopes (delta13C, delta15N) and trace elements (Zn, Cu, Fe, Se, total Hg and Cd), in relation to habitat characteristics (bathymetry) and geographic position (latitude). RESULTS: Among the trace elements analysed, only Cd, with an oceanic specific food origin, was found to be useful as an ecological tracer. All other trace elements studied were not useful, most likely because of physiological regulation and/or few specific sources in the food web. The delta13C, delta15N signatures and Cd levels were highly correlated with each other, as well as with local bathymetry and geographic position (latitude). Variation in the isotopic ratios indicated a shift in harbour porpoise's feeding habits from pelagic prey species in deep northern waters to more coastal and/or demersal prey in the relatively shallow North Sea and Skagerrak waters. This result is consistent with stomach content analyses found in the literature. This shift was associated with a northward Cd-enrichment which provides further support to the Cd 'anomaly' previously reported in polar waters and suggests that porpoises in deep northern waters include Cd-contaminated prey in their diet, such as oceanic cephalopods. CONCLUSION: As stable isotopes and Cd provide information in the medium and the long term respectively, the spatial variation found, shows that harbour porpoises experience different ecological regimes during the year along the Scandinavian coasts, adapting their feeding habits to local oceanographic conditions, without performing extensive migration.

The objective of this study is to describe the eating representations and practices among 60 Roman high-school boys and girls through a complex methodology scheme that associates different techniques (word-association network, semi-directive interviews, test on the drawing of eating contexts, eating attitudes scale). As a result, it emerges that there are two differentiated models of relationship – depending on the sex and the socio-professional category the high-school pupils belong to – to eating and body. A protective model, typical among boys, shows an essentially pleasure-based relationship to eating and body. Eating contexts are lived in a conflicting (family) and play (friends) manner. This model seems to be a factor of preservation against eating pathology risks. On the contrary, a model that presents risks of eating disorders, typical among girls, shows a more complex relationship to eating and to body, characterized by normative aspects that girls shall conform to and/or transgress, according to the eating context. In this kind of relationship, the test on the drawing of the family eating context shows, among other things, the absence of any contact with food. [less ▲]

1. Introduction Chronic hepatitis B virus (HBV) infection currently affects about 400 million people and is responsible for 500,000 to 1,000,000 deaths annually worldwide from cirrhosis and hepatocellular carcinoma (HCC) (1). For this reason, screening high risk populations to identify HBV infected persons is important so that guidelines for treatment and prevention of transmission can be given in this specific group. Recently, new drugs became available for HBV and new insights in resistance and definitions came up. So, the purpose of this paper is providing an update of the recent literature and guidelines concerning 1. screening for chronic hepatitis B (CHB) 2. management of patients with CHB 3. treatment of CHB in mono-infected patients and in special patient populations (co-infected, transplanted and immunosuppressed patients). The recommendations are based onpublished information and the level of evidence is reported with each recommendation. The level of evidence is graded as :grade 1 : randomized controlled trials ; grade II-1 : controlled trials without randomization ; grade 11-2 : cohort or case-control analytic study ; grade 11-3 : multiple time series, dramatic uncontrolled experiments ; grade III : descriptive epidemiology, expert opinions.

RT29 is a dicationic diamidine derivative that does not obey the classical "rules" for shape and functional group placement that are expected to result in strong binding and specific recognition of the DNA minor groove. The compound contains a benzimidazole diphenyl ether core that is flanked by the amidine cations. The diphenyl ether is highly twisted and gives the entire compound too much curvature to fit well to the shape of the minor groove. DNase I footprinting, fluorescence intercalator displacement studies, and circular dichroism spectra, however, indicate that the compound is an AT specific minor groove binding agent. Even more surprisingly, quantitative biosensor-surface plasmon resonance and isothermal titration calorimetric results indicate that the compound binds with exceptional strength to certain AT sequences in DNA with a large negative enthalpy of binding. Crystallographic results for the DNA complex of RT29 compared to calculated results for the free compound show that the compound undergoes significant conformational changes to enhance its minor groove interactions. In addition, a water molecule is incorporated directly into the complex to complete the compound-DNA interface, and it forms an essential link between the compound and base pair edges at the floor of the minor groove. The calculated DeltaCp value for complex formation is substantially less than the experimentally observed value, which supports the idea of water being an intrinsic part of the complex with a major contribution to the DeltaCp value. Both the induced fit conformational changes of the compound and the bound water are essential for strong binding to DNA by RT29. [less ▲]

The influence of annealing atmosphere oxidation potential on the surface condition of an industrial dual-phase steel alloyed with 2 wt% Mn and 0.3 wt% mo has been studied by galvanizing simulation, with particular attention towards alloying element segregation, the occurrence of selective oxidation of the surfaces immediately prior to hot-dip galvanizing and their effect on reactive wetting and coating adherence. The surface chemistry and morphology prior to dipping have been analyzed in detail, along with their evolution during annealing, and the coating quality and chemistry were characterized and interpreted in relation to the surface condition prior to dipping.

INTRODUCTION: Studies suggest an important role of disturbances of self in schizophrenia and in schizotypy. Based on findings from a previous study (Bredart & Young, 2004), we developed a questionnaire assessing self-face recognition failures in everyday life (Self-Face Recognition Questionnaire; SFRQ) to investigate the relations between dimensions of schizotypy (cognitive-perceptual, interpersonal, disorganised) and self-face recognition disturbances. METHODS: A sample of nonclinical participants (n = 170) completed the SFRQ and the Schizotypal Personality Questionnaire. RESULTS: Factor analysis of SFRQ items revealed a clear three-factor structure consisting of: (1) self-face recognition difficulties, (2) unusual perception of own or other faces, and (3) other-face recognition difficulties. Correlational analyses between schizotypy dimensions and the SFRQ revealed that only the cognitive-perceptual and disorganised schizotypy dimensions correlated significantly with the SFRQ. By contrast, the interpersonal schizotypy dimension was not associated with the SFRQ. CONCLUSIONS: Findings provide further support that positive (cognitive-perceptual) and negative (interpersonal) schizotypy represent discrete neurobehavioural dimensions. The theoretical implications of these findings are discussed. [less ▲]

Arterial hypertension is a significant risk factor for cardiovascular disease, proportional to the blood pressure level. Treating hypertension reduces the risk. Until recently, beta-blockers were considered as a first line class for hypertension management. The British Hypertension Society has recently pronounced that using beta-blockers as first line antihypertensive therapy is no good choice since these agents are less protective than other antihypertensive classes against cardiovascular disorders and diabetes mellitus, especially when used in association with diuretics.

Around 30 sites have yielded Gravettian assemblages in Belgium. Present fairly early (28,000 BP), the Gravettian appears in trios distinct facies. The earliest includes large pointed blades and tanged tools; the most recent is marked by microlithic backed elements (truncated elements, microgravettes). These facies likely correspond to regional groups, for which the first can also be found fairly easily in neighbouring regions (England, Wales and northern France). In Rhenania, some 15 sites correspond to two facies (with Font Robert points and with microgravettes), similar but not identical to the Belgian facies. [less ▲]

We report DNA immunisation experiments in cattle using plasmid constructs that encoded glycoprotein E2 from bovine viral diarrhoea virus (BVDV)-1 (E2.1) and BVDV-2 (E2.2). The coding sequences were optimised for efficient expression in mammalian cells. A modified leader peptide sequence from protein gD of BoHV1 was inserted upstream of the E2 coding sequences for efficient membrane export of the proteins. Recombinant E2 were efficiently expressed in COS7 cells and they presented the native viral epitopes as judged by differential recognition by antisera from cattle infected with BVDV-1 or BVDV-2. Inoculation of pooled plasmid DNA in young cattle elicited antibodies capable of neutralising viral strains representing the major circulating BVDV genotypes. [less ▲]
