Zebrafish were proposed as an alternative to mammalian models to assess the efficacy and toxicity of antileukemic drugs. Due to the limited number of transgenic zebrafish leukemia models, we explored human leukemic cell xenograft in zebrafish embryos. Human leukemic cell lines and blast cells sorted from patients with acute myelogenous leukemia were injected 48 hours post-fertilization and remained in the circulation of zebrafish embryos for several days without affecting their development. Imatinib and oxaphorines did not demonstrate any toxicity on normal zebrafish embryos and decreased the leukemic burden in animals xenografted with sensitive leukemic cell lines. Two other molecules, all-trans retinoic acid and the translation inhibitor 4EGI-1, demonstrated teratogenic effects at concentrations shown to be efficient in vitro, which precluded investigation of their antileukemic activity in such models. Altogether, xenografted leukemic cells in zebrafish embryos are a pharmacologically relevant model for screening non-teratogenic drugs. [less ▲]

Background With aging, the barrier repair kinetics following any weakening of the epidermal permeability barrier function is commonly slowed down. Objective To assess the recovery rate of the epidermal permeability barrier function following controlled stripping and applications of samphire and control formulations. Method In 12 healthy subjects older than 50 years, controlled stratum corneum (SC) strippings were used to increase the transepidermal water loss (TEWL) just above 15 g/m(2) /h. This procedure followed a 14-day skin preconditioning by daily applications of formulations enriched or not with a samphire (Crithmum maritimum) biomass. An untreated skin site served as control. The epidermal permeability repair kinetics was assessed for 14 days by daily measurements of both TEWL and the colorimetric value a*. Results A rapid (96 h) recovery to lower TEWL values was obtained at each of the samphire-preconditioned sites (0.1% serum, 0.05% cream, the serum-cream association, and 0.5% silicone oil). This process was significantly (P < 0.001) faster than that on both the placebo-preconditioned (silicone oil) and the untreated sites. No adverse inflammatory and sensory reactions were recorded. At the sites preconditioned by samphire formulations, the SC moisture (capacitance) was higher at completion of the study compared to inclusion. Conclusions The present experimental pilot study brings some clues supporting a beneficial boosting effect of samphire cell biomass on the kinetics of epidermal permeability barrier repair. [less ▲]

Bovine tuberculosis (BTB) is a chronic and contagious disease that affects domestic animals, wildlife, and humans. Caused by Mycobacterium bovis, BTB causes major economic losses and poses a serious constraint to international livestock trade. Moreover, in developing countries where BTB controls are lacking, M. bovis is a public health concern. In most developing countries, the prevalence of BTB in livestock is unknown because the information is either not reported or not available. In Ecuador, there is no national BTB control program. This article reviews the BTB situation in Ecuador by examining exhaustive data from tuberculin testing surveys and slaughterhouse surveillance studies conducted in 1972–2008 in a variety of the country’s geographic areas. In Ecuador, several factors, including the dairy industry’s expansion (preempted by the high demand for milk and its byproducts), intensified efforts to increase the cattle population, the presence of M. bovis, and a lack of BTB controls, have caused a rise in BTB prevalence, and consequently, a growing push for the implementation of a national BTB control program.

An in situ ventilation test (SDZ) is performed by the French national radioactive waste management agency (ANDRA) in the Meuse/Haute-Marne underground research laboratory. The aim is to characterise the effect of the desaturation and possible resaturation of the damaged zone located around an experimental gallery due to controlled ventilation imposed in this gallery. Hydro and hydro-mechanical numerical modellings are realised in order to acquire a better understanding of clayey rock behaviour and transfers occurring during the test. [less ▲]

The present study investigates the combined effect of phosphorous limitation, elevated partial pressure of CO2 (pCO2) and temperature on a calcifying strain of Emiliania huxleyi (PML B92/11) by means of a fully controlled continuous culture facility. Two levels of phosphorous limitation were consecutively applied by renewal of culture media (N:P = 26) at dilution rates (D) of 0.3 d− 1 and 0.1 d− 1. CO2 and temperature conditions were 300, 550 and 900 μatm pCO2 at 14 °C and 900 μatm pCO2 at 18 °C. In general, the steady state cell density and particulate organic carbon (POC) production increased with pCO2, yielding significantly higher concentrations in cultures grown at 900 μatm pCO2 compared to 300 and 550 μatm pCO2. At 900 μatm pCO2, elevation of temperature as expected for a greenhouse ocean, further increased cell densities and POC concentrations. In contrast to POC concentration, C-quotas (pmol C cell− 1) were similar at D = 0.3 d− 1 in all cultures. At D = 0.1 d− 1, a reduction of C-quotas by up to 15% was observed in the 900 μatm pCO2 at 18 °C culture. As a result of growth rate reduction, POC:PON:POP ratios deviated strongly from the Redfield ratio, primarily due to an increase in POC. Ratios of particulate inorganic and organic carbon (PIC:POC) ranged from 0.14 to 0.18 at D = 0.3 d− 1, and from 0.11 to 0.17 at D = 0.1 d− 1, with variations primarily induced by the changes in POC. At D = 0.1 d− 1, cell volume was reduced by up to 22% in cultures grown at 900 μatm pCO2. Our results indicate that changes in pCO2, temperature and phosphorus supply affect cell density, POC concentration and size of E. huxleyi (PML B92/11) to varying degrees, and will likely impact bloom development as well as biogeochemical cycling in a greenhouse ocean.

Carbon capture and storage is a technology that can contribute to face the challenge of rising energy demand combined with a growing environmental awareness. In the present work, the CO2 capture process with monoethanolamine (MEA) is modeled using the simulation tool Aspen Plus. Two different modeling approaches are studied and compared: the equilibrium and the rate-based approaches. An optimization of key process parameters is performed and process modifications are studied with the objective of improving the global process energy efficiency. [less ▲]

The status of the axillary lymph nodes is one of the most important prognostic factors in women with early stage breast cancer. Histologic examination of removed lymph nodes is the most accurate method for assessing spread of disease to these nodes. Axillary lymph node dissection (ALND) remains the standard approach for women who have clinically palpable axillary nodes. The benefits of ALND include its impact on disease control (axillary recurrence and survival), its prognostic value, and its role in treatment selection. However, the anatomic disruption caused by ALND may result in lymphedema, nerve injury, and shoulder dysfunction, which compromise functionality and quality of life. For patients who have clinically negative axillary lymph nodes, sentinel lymph node (SLN) biopsy offers a less morbid method to determine if there are positive nodes, in which case axillary node dissection would be necessary. Patients who are SLN-positive should undergo complete ALND. Axillary reverse mapping (ARM) is a recent improvement of ALND which, like the biopsy of the GS, would reduce morbidity. [less ▲]

Questionner le tourisme rural, c’est se poser la question des particularités de celui-ci notamment liées à sa dispersion, à ses difficultés d’organisation en une « destination », à ses représentations idylliques, à ce patrimoine plus ou moins commun, plus ou moins privatisé, que le touriste consomme, aux difficiles questions du partage des revenus du développement touristique, aux problèmes des équipements et surtout de l’accessibilité par transports individuels et collectifs de ces zones excentrées. Autour de quelques collègues soucieux de partager leur enthousiasme pour la recherche, nous avons convié des doctorants à partager dans le cadre d’une journée de l’école doctoral thématique en géographie auprès du Fonds National de la Recherche Scientifique, leurs interrogations et leurs premières investigations. Ce numéro thématique rassemble les principales contributions à cette réflexion commune, en proposant une étude de l'utilisation de l’autoroute pour développer des produits touristiques à proximité d’un flux important de personnes (Malet, 21-35), une analyse de la mise en tourisme d'un produit de terroir et de la manière d'en faire une ressource clé du tourisme régional (De Myttenaere, 37-51), une recherche sur les images et représentations d'une destination rurale et leur utilisation pour développer l’accueil et la promotion (Mazuel et Bonniot, 7-19), une enquête sur le rôle des associations intercommunales et des municipalités dans le développement des entreprises touristiques en milieu rural (Vanneste et Ryckaert 53-71), une réflexion sur la complexité des polémiques autour des loisirs motorisés (Haye et Mounet, 73-84) et enfin une lecture critique de textbooks anglais qui permet de constater le chemin fait et le chemin qui reste à faire pour réellement passer des monographies à des théories du tourisme sensibles aux particularités du milieu rural (Dubois, 85-94).
