Q fever is a zoonotic infection caused by Coxiella burnetii that is endemic worldwide. Domestic ruminants are a source of infection for humans. Given the suggestion that the bacterium recrudesces during pregnancy in cattle, this study was designed to determine whether C. burnetii infection affects hormonal patterns, such as progesterone, cortisol, pregnancy associated glycoproteins (PAG), and prolactin during gestation in lactating cows. Possible interactions with Neospora caninum were also explored. The study was performed on 58 gestating non-aborting cows. Blood samples for hormone determinations were collected on Days 40, 90, 120, 150, 180, and 210 of gestation. For antibody determinations, blood was collected at day 40 postinsemination and postpartum. By GLM repeated measures analysis of variance, we established the effects of production and reproductive variables as well as Coxiella and Neospora seropositivity related to changes on cortisol, PAG, progesterone, and prolactin levels. Coxiella antibody levels were significantly related to cortisol, PAG, and plasma progesterone concentrations, whereas Neospora seropositivity was linked to plasma progesterone concentrations. The interaction between Coxiella and Neospora seropositivity was correlated with cortisol and plasma progesterone levels, whereas the interaction seropositivity against C. burnetii-plasma cortisol concentration was related to plasma PAG levels. Finally, an effect of lactation number only was observed on plasma prolactin. Our findings suggest that both the N. caninum and C. burnetii infection or the presence of both modify endocrine patterns throughout gestation. Cows seropositive to both, Neospora and Coxiella, showed higher plasma progesterone levels than the remaining animals examined. Seropositivity to C. burnetii was associated with placental damage and diminishing PAG levels throughout the second half of gestation, along with increased plasma cortisol levels on Day 180 of gestation.

Current theories on the evolution of paedomorphosis suppose that several ontogenetic pathways have appeared according to different selective pressures. The aim of this study was to find out whether two distinct processes can lead to paedomorphosis in the Alpine newt, Triturus alpestris. In this respect, we compared age structures of paedomorphic and metamorphic individuals in two newt populations where the two forms lived syntopically. Whereas paedomorphosis resulted in a slower rate of somatic development in one population, it resulted in an acceleration of sexual maturation in the other population. These processes correspond to neoteny and progenesis, respectively. These results suggest that phenotypic plasticity can result from contrasted ontogenetic pathways between two populations of the same species. They give support to models that consider gonadic development as the target of selection under different environmental pressures. [less ▲]

Diabetic nephropathy is a constantly increasing pathology in western countries. The trend is more pronounced in type 2 diabetic patients than in type 1 diabetic patients. Among individuals with type 2 diabetes, kidney disease is often multifactorial. This paper reviews recent developments in the pathophysiology, epidemiology and treatment of diabetic nephropathy.

L'Entre-Sambre-et-Meuse a été le siège d'une épidémie de néphropathie épidémique à Hantavirus (NE) en 199293. Cinq cas ont été rencontrés au CHU de Liège en moins d'un an. Le virus responsable de cette affection appartient à la famille dès Hantavirus dont il existe huit sérotypes aux caractéristiques propres en terme de vecteur (rongeurs), de distribution géographique et de pathogénicité. Les pathologies induites chez l'homme vont de la néphropathie épidémique à Hantavirus - d'évolution le plus souvent bénigne- au syndrome pulmonaire à Hantavirus (SPH) - fréquemment mortel - en passant par la fièvre hémorragique avec syndrome rénal (FHSR) de sévérité intermédiaire. Dans nos contrées, on rencontre le sérotype Puumala dont le vecteur est le campagnol roussâtre. L'homme s'infecte par inhalation de particules contaminées et développe dans un pourcentage non précisé des cas, après une période d'incubation de 1 à 3 semaines, un tableau clinique de néphropathie épidémique à Hantavirus. Celui-ci se caractérise par l'apparition brutale d'une fièvre, de myalgies diffuses, de douleurs abdominales et/ou lombaires et de céphalées. Apparaissent ensuite à des degrés divers: nausées et vomissements, oligurie, myopie aiguë, toux,diathèse hémorragique, diarrhée... Biologiquement, on observe l'association d'une insuffisance rénale aiguë et d'une thrombopénie. L'évolution est spontanément favorable dans les deux à trois semaines. Le diagnostic suggéré par la clinique sera confirmé par la sérologie. La physiopathologie de l'insuffisance rénale et de la thrombopénie fait intervenir des interactions complexes entre l'hôte et le virus. Il n'existe pas de thérapeutique spécifique pour la néphropathie épidémique à Hantavirus. Les formes plus sévères (SPH et FHSR) peuvent bénéficierd'un traitement par Ribavirineen iv. [less ▲]

We report the case of an acute renal failure due to an acute interstitial nephropathy (ATIN) induced by non steroidal anti-inflammatory drugs (NSAID). Even though this pathology is a rare cause of acute renal failure, it still requires special attention in view of the fact that it induces a high risk of acute morbidity but it also can evolve into chronic renal failure. Its differential diagnosis with other causes of acute renal failure becomes essential because of the different therapeutic care. In this article, we are going to briefly sum up the reasoning to adopt in order to diagnose an acute renal failure. [less ▲]

An empirical model called NeQuick has been selected for the modelling and correction of the ionospheric delay contribution in GALILEO single frequency receivers. The current baseline version of NeQuick for GALILEO is the one available in the International Telecommunication Union – Radiocommunication Sector (ITU-R) since 2001. From that time, several improvements have been proposed leading to the need of a better understanding and comparison of these different versions and an analysis of the weaknesses. Better results have been obtained by means of simpler ionosonde and profile parameters calculations, different topside formulation and new data files. The interest of a newer version of NeQuick including the above-mentioned modifications is highlighted as its error behaviour towards latitude shows a better agreement with reality. Those modifications should be coupled to a less simplistic topside formulation involving several layers with appropriate transitions such as the proposal introduced in this paper. The need of a different treatment regarding the daily effective use of the model for GALILEO single frequency algorithm compared to a physical use (that uses monthly median underlying data) is addressed. For the analysis and comparison of the different variants of the model, a software tool with a Graphical User Interface was developed. Preliminary comparisons for the physical use between different versions and also between modelled and measured data are presented. Such comparisons should be extended in the future for the effective use of the model. Finally, the structure and analysis of the mentioned issues and the results of the different comparisons are shown. Also solutions or potential paths to investigate solutions are proposed. [less ▲]
