Selenium (Se), iodine (I), zinc (Zn) and copper (Cu) deficiencies in cattle have been reported in Europe. These deficiencies are often associated with diseases. The aim of the study was to assess trace element status in Belgian cattle herds showing pathologies and to compare them to healthy cattle herds. Eighty-two beef herds with pathologies, 11 healthy beef herds, 65 dairy herds with pathologies and 20 healthy dairy herds were studied during barn period. Blood and/or milk samples were taken in healthy animals. Plasma Zn, Cu, inorganic I (PII) and activity of glutathione peroxidase in erythrocytes (GPX) were assayed. In milk, I concentration was measured. Data about pathologies and nutrition in the herds were collected. According to defined thresholds, it appeared that a large proportion of deficient herds belonged to "sick" group of herds. This conclusion was supported by the mean value of trace elements and by the fact that a majority of individual values of trace elements was below the threshold. Dairy herds had mean values of trace elements higher than beef herds. More concentrates and minerals were used in healthy herds versus "sick" herds. These feed supplements were also used more often in dairy herds, compared to beef herds. Trace elements deficiencies are present in cattle herds in Belgium and are linked to diseases. Nutrition plays a major role in the trace elements status. [less ▲]

Ce texte traite des politiques de lutte contre le travail des enfants au Burkina Faso dans une perspective historique, en cherchant à comprendre comment le travail des enfants a été construit comme « problème » dans les politiques publiques . Le but est d’explorer l’origine des politiques contemporaines de lutte contre le travail des enfants dans ce pays, en remontant aux politiques coloniales françaises en Haute-Volta, actuel Burkina Faso. Nous nous proposons de répondre à la question suivante : Face à l’émergence et au renforcement des politiques publiques de lutte contre le travail des enfants au Burkina Faso, assiste-t-on à un ratissage du modèle de l’enfant du lignage qui percevait l’enfant comme une « richesse » et une force de travail complémentaire? Ceci nous permettra d’analyser l’évolution et la portée de l’intervention des pouvoirs publics pour imposer une nouvelle vision de l’enfant (l’enfant de la Nation). Enfin, nous interrogerons la place réservée à l’ « enfant travailleur » dans ces politiques. [less ▲]

The modeling of carbon nanotube production by the CCVD process in a continuous rotary reactor with mobile bed was performed according to a rigorous chemical reaction engineering approach. The geometric, hydrodynamic, physical and physicochemical factors governing the process were analyzed in order to establish the reactor equations. While the study of the hydrodynamic factor suggests a co-current plug-flow approximation, the physical factor mainly deals with the phenomena of transport and the transfer of mass, which can be neglected. Concerning the physicochemical factor, the modeling is based on knowledge of the expression of the initial reaction rate, and takes into account catalytic deactivation as a function of time, according to a sigmoid decreasing law. The reactor modeling allows obtaining the evolution of partial pressure, carbon nanotube production and catalytic deactivation along the reactor for given initial operating conditions. The comparison between experimental and calculated production highlights a very good fit of data. (c) 2009 American Institute of Chemical lEngineers AIChE J, 55: 675-686, 2009 [less ▲]

Determination Of The Minimal Fusion Peptide Of Hiv, Siv And Blv Fusion Glycoproteins

The entry of enveloped viruses into target cells requires the fusion between the viral envelope and the target cell membrane. In the case of many viruses like HIV, SIV and BLV, the fusion is mediated by class 1 fusion glycoproteins located on the viral envelope. These fusion glycoproteins contain a region at their N-terminal extremity called the “fusion peptide”, which interact with the target membrane. Many mutagenesis studies showed that this region is required for mediating membrane fusion [1]. Moreover, synthetic peptides corresponding to the fusion peptide of many glycoproteins induce membrane fusion in vitro. Despite the large number of studies on synthetic fusion peptides, the region necessary and sufficient to induce optimal membrane fusion is not known. To determine this minimal fusion peptide, we used the “tilted peptide” theory. According to this theory, a helical peptide inserting obliquely into membranes induces fusion [2]. Moreover, the more tilted the peptide is, the more important the fusion is. Then, we postulate that the minimal fusion peptide corresponds to the shortest helical fragment able to insert into the membrane with an angle close to 45°. This peptide was predicted using the IMPALA algorithm, which allow to predict peptide-membrane interactions [3]. Fusogenicity of this peptide was then assessed in liposome lipid-mixing and leakage assays and compared to the fusogenicity of smaller and longer peptides to check the validity of the prediction. This methodology was used to determine successfully the minimal fusion peptide of three viruses, HIV, SIV and BLV. [less ▲]
