La pêche industrielle des poissons démersaux en Côte d'Ivoire. Généralités, localisation, homogéneité relative des zones de pêche ivoiriennes

This paper describes the fishery of Côte d'Ivoire and its evolution to the present day. The location of fishing off Côte d'Ivoire is specified for each area and each type of trawler. A comparison of productivity between the different areas shows disparities that allow to make clearer the repartition of effort of all types of trawlers in each area. The Côte d'Ivoire continental shelf is populated with demersal stocks of homogeneous densities.

«Et ferez justice» : le métier d’intendant au Canada et dans les généralités de Bretagne et de Tours au 18e siècle (1700-1750)

Cette thèse consiste en une étude comparative du métier d’intendant au Canada et dans les généralités de Bretagne et de Tours dans la première moitié du 18e siècle (1700-1750). Elle s’appuie sur l’intendant pour s’interroger sur l’existence de spécificités dans l’exercice du pouvoir en contexte colonial par rapport au contexte métropolitain. Considéré par la plupart des historiens de la France d’Ancien Régime comme le personnage clé de l’évolution politique qui aurait fait passer la monarchie de sa phase judiciaire jusqu’à sa phase dite « administrative », l’intendant de justice, police et finance ou commissaire départi est au coeur des débats sur l’absolutisme et son rôle de première ligne dans l’oeuvre de centralisation monarchique en fait le sujet idéal pour observer la portée réelle de ce régime sur le terrain. L’examen du fonctionnement de l’intendance est un préalable obligé pour qui veut comprendre les rapports entre administrateurs et administrés et mieux cerner la capacité de régulation de l’État. Dans le cadre des attributions définies par sa commission, quelles sont les tâches qui l’occupent concrètement ? Cette thèse s’intéresse à l’intendant du point de vue de sa pratique, en s’appuyant sur la description interne des sources produites par l’intendant pour décortiquer ses mécanismes d’intervention. Deux types de documents sont analysés successivement, soit la correspondance, incluant les pièces jointes et les documents de travail, et les actes de portée réglementaire, incluant les ordonnances et les arrêts du Conseil d’État. Chemin faisant, nous avons fait la rencontre des individus et groupes qui sollicitent l’intervention de l’intendant, levant le voile sur les rapports de pouvoir et les interactions qui le lient à ses supérieurs, aux justiciables et aux institutions locales. L’exercice permet de poser en des termes nouveaux l’action de ce personnage dont on connaissait les attributions et principales décisions, mais beaucoup moins leur logique sous-jacente.

Structures of P-glycoprotein reveal its conformational flexibility and an epitope on the nucleotide-binding domain

P-glycoprotein (P-gp) is one of the best-known mediators of drug efflux-based multidrug resistance in many cancers. This validated therapeutic target is a prototypic, plasma membrane resident ATPBinding Cassette transporter that pumps xenobiotic compounds out of cells. The large, polyspecific drug-binding pocket of P-gp recognizes a variety of structurally unrelated compounds. The transport of these drugs across the membrane is coincident with changes in the size and shape of this pocket during the course of the transport cycle. Here, we present the crystal structures of three inward-facing conformations of mouse P-gp derived from two different crystal forms. One structure has a nanobody bound to the C-terminal side of the first nucleotide-binding domain. This nanobody strongly inhibits the ATP hydrolysis activity of mouse Pgp by hindering the formation of a dimeric complex between the ATP-binding domains, which is essential for nucleotide hydrolysis. Together, these inward-facing conformational snapshots of P-gp demonstrate a range of flexibility exhibited by this transporter, which is likely an essential feature for the binding and transport of large, diverse substrates. The nanobody-bound structure also reveals a unique epitope on P-gp.

Ontogeny of mouse B lymphocytes and inactivation by antigen of early B lymphocytes

Taking advantage of recent findings about membrane fluidity, the authors studied and compared the biosynthetic capacities of fetal or neonatal mouse B (bone marrow derived) lymphocytes (until 10 days after birth) and adult B lymphocytes. Although both early and adult lymphocytes can synthesize surface immunoglobulins, they have a different physiological behavior after interaction with a ligand (anti immunoglobulin sera or antigen), either in vivo or in vitro. Fetal and neonatal lymphocytes bearing surface immunoglobulins do not reexpress their membrane receptors after capping and endocytosis promoted by anti immunoglobulin sera. On the other hand, adult lymphocytes resynthesize completely their receptors after the same treatment. Furthermore, intrafetal injections of hemocyanin in pregnant mice lead to a striking decrease in the number of hemocyanin binding cells. It seems plausible that this non reexpression of surface immunoglobulins could be the first step in tolerance establishment.

Broadband pulse propagation with electromagnetically induced transparency: Splitting of adiabatic and nonadiabatic components

The propagation of a broadband pulse through a dense resonant medium with a narrow transparency window is considered. We show that the pulse splits into a slowly propagating adiabatic part and a fast nonadiabatic part. © 2005 Optical Society of America.

Expression, purification and X-ray crystallographic analysis of the Helicobacter pylori blood group antigen-binding adhesin BabA

Helicobacter pylori is a human pathogen that colonizes about 50% of the world's population, causing chronic gastritis, duodenal ulcers and even gastric cancer. A steady emergence of multiple antibiotic resistant strains poses an important public health threat and there is an urgent requirement for alternative therapeutics. The blood group antigen-binding adhesin BabA mediates the intimate attachment to the host mucosa and forms a major candidate for novel vaccine and drug development. Here, the recombinant expression and crystallization of a soluble BabA truncation (BabA^25-460) corresponding to the predicted extracellular adhesin domain of the protein are reported. X-ray diffraction data for nanobody-stabilized BabA^25-460 were collected to 2.25Å resolution from a crystal that belonged to space group P21, with unit-cell parameters a = 50.96, b = 131.41, c = 123.40Å, α = 90.0, β = 94.8, γ = 90.0°, and which was predicted to contain two BabA^25-460-nanobody complexes per asymmetric unit.

Global carbon dioxide emissions from inland waters

Carbon dioxide (CO2) transfer from inland waters to the atmosphere, known as CO2 evasion, is a component of the global carbon cycle. Global estimates of CO2 evasion have been hampered, however, by the lack of a framework for estimating the inland water surface area and gas transfer velocity and by the absence of a global CO2 database. Here we report regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity. We obtain global CO2 evasion rates of 1.8petagrams of carbon (Pg C) per year from streams and rivers and 0.32Pg Cyr-1 from lakes and reservoirs, where the upper and lower limits are respectively the 5th and 95th confidence interval percentiles. The resulting global evasion rate of 2.1 Pg Cyr-1 is higher than previous estimates owing to a larger stream and river evasion rate. Our analysis predicts global hotspots in stream and river evasion, with about 70 per cent of the flux occurring over just 20 per cent of the land surface. The source of inland water CO2 is still not known with certainty and new studies are needed to research the mechanisms controlling CO2 evasion globally. © 2013 Macmillan Publishers Limited.

Toward understanding the essence of post-translational modifications for the Mycobacterium tuberculosis immunoproteome

CD4⁺ T cells are prominent effector cells in controlling Mycobacterium tuberculosis (Mtb) infection but may also contribute to immunopathology. Studies probing the CD4⁺ T cell response from individuals latently infected with Mtb or patients with active tuberculosis using either small or proteome-wide antigen screens so far revealed a multi-antigenic, yet mostly invariable repertoire of immunogenic Mtb proteins. Recent developments in mass spectrometry-based proteomics have highlighted the occurrence of numerous types of post-translational modifications (PTMs) in proteomes of prokaryotes, including Mtb. The well-known PTMs in Mtb are glycosylation, lipidation, or phosphorylation, known regulators of protein function or compartmentalization. Other PTMs include methylation, acetylation, and pupylation, involved in protein stability. While all PTMs add variability to the Mtb proteome, relatively little is understood about their role in the anti-Mtb immune responses. Here,we reviewMtb protein PTMs and methods to assess their role in protective immunity against Mtb. © 2014 van Els, Corbière, Smits, vanGaans-van den Brink, Poelen, Mascart, Meiring and Locht.

Social tourism today: Stakeholders, and supply and demand factors

As highlighted in the previous chapter, the definitions and consequently the expression of social tourism have developed and changed since its inception in the 19th century. In post-modern times there has been a significant evolution of the needs, the expectations and the possibilities (or opportunities) for holidaymaking and travel in general for the majority of people in Europe. Socio-political, economic and technological developments have forged a new context for tourism and created new travel opportunities (see Chapter 6). While the numbers of tourism trips have grown steadily over time, tourism participation levels in Europe have largely stabilised: there are still a number of groups in contemporary society who are excluded from tourism. Social tourism has adapted to societal changes and has changed its focus from factory workers and manual labourers towards the current main four target groups.
