The baryon spectra are discussed in the context of the $1/N_c$ expansion approach, with emphasis on mixed symmetric states. The contributions of the spin dependent terms as a function of the excitation energy are shown explicitly. At large energies these contributions are expected to vanish. [less ▲]

In Medical Microbiology, in addition to the direct methods of indentification of infectious agentss, the serologic indirect techniques by quantification of antibodies have extremely useful in infectiology, for the diagnosis and the therapeutic or vaccination follow-up as well as for epidemiologic enquiries, serodiagnosis methods have significantly improved. Meanwhile, results may reveal hard to interpret, especially when are tries to specify the time of the beginning of an infection. The results require in the majority of the cases to be compared on two subsequent serum samples, to observe a possible increase in antibodies level. In addition, the infectious serology results may not be considered as the only element of final diagnosis. In all cases, they have to be interpreted and challenged against the clinical context.

Serpins (serine protease inhibitors) are a large family of structurally related proteins found in a wide variety of organisms, including hematophagous arthropods. Protein analyses revealed that Iris, previously described as an immunomodulator secreted in the tick saliva, is related to the leukocyte elastase inhibitor and possesses serpin motifs, including the reactive center loop (RCL), which is involved in the interaction between serpins and serine proteases. Only serine proteases were inhibited by purified recombinant Iris (rIris), whereas mutants L339A and A332P were found devoid of any protease inhibitory activity. The highest Ka was observed with human leukocyte-elastase, suggesting that elastase-like proteases are the natural targets of Iris. In addition, mutation M340R completely changed both Iris substrate specificity and affinity. This likely identified Met-340 as amino acid P1 in the RCL. The effects of rIris and its mutants were also tested on primary hemostasis, blood clotting, and fibrinolysis. rIris increased platelet adhesion, the contact phase-activated pathway of coagulation, and fibrinolysis times in a dose-dependent manner, whereas rIris mutant L339A affected only platelet adhesion. Taken together, these results indicate that Iris disrupts coagulation and fibrinolysis via the anti-proteolytic RCL domain. One or more other domains could be responsible for primary hemostasis inhibition. To our knowledge, this is the first ectoparasite serpin that interferes with both hemostasis and the immune response.

This paper will illustrate the choice of the alloying elements and their content in the current grade. By using sophisticated laboratory examination techniques such as differential thermal analysis, scanning electron microscopy and image analysis, the metallurgical parameters of Aurora grade will be described and compared to those of the Kosmos grade. An attempt will also be made to connect all our laboratory results to the good behaviour of the alloy in operation in the early stands of Hot Strip Mills. [less ▲]

Les marges sud et nord du Sahara sont soumises à des processus de dégradation anciens attestés par de nombreux travaux de terrain. Ils coïncident avec l'occurrence d'une sécheresse sévère sur les 3 sites d'étude, débutée dans les années 1970 en Algérie (piémont sud de l'Atlas Saharien), au Maroc (bassin de l'oued Dadès) et en Mauritanie (lac d'Aleg, Brakna). Les suivis diachroniques par télédétection satellitaire (Landsat et SPOT) et aérienne (1954 à 2002) et des observations récentes, montrent la pérennité voire l'extension de certaines zones de dégradation localisées à proximité des agglomérations et points d'eau, malgré le retour des précipitations. Le rythme et les modalités de développement des dynamiques en œuvre, qui prennent la forme d'une dégradation qualitative et quantitative des couverts végétaux steppiques et de savane ainsi qu'une revivification des dunes d'Aleg, attestent du rôle prépondérant de certains activités humaines dans les processus de dégradation de ces milieux, en corrélation avec la crise climatique dont on peut se demander si elle n'est pas devenue un facteur secondaire. Sans ignorer les enjeux socio-économiques de développement, notre démarche vise à comprendre les logiques d'action des dynamiques complexes parfois abusivement désignées sous le terme simplificateur de «désertification».

The sesquiterpenoid juvenile hormone (JH) regulates insect development and reproduction. Most insects produce only one chemical form of JH, but the Lepidoptera produce four derivatives featuring ethyl branches. The biogenesis of these JHs requires the synthesis of ethyl-substituted farnesyl diphosphate (FPP) by FPP synthase (FPPS). To determine if there exist more than one lepidopteran FPPS, and whether one FPPS homolog is better adapted for binding the builder ethyl-branched substrates/products, we cloned three lepidopteran FPPS cDNAs, two from Choristoneura fumiferana and one from Pseudaletia unipuncta. Amino acid sequence comparisons among these and other eukaryotic FPPSs led to the recognition of two lepidopteran FPPS types. Type-I FPPSs display unique active site substitutions, including several in and near the first aspartaterich motif, whereas type-II proteins have a more "conventional" catalytic cavity. In a yeast assay, a Drosophila FPPS clone provided full complementation of an FPPS mutation, but lepidopteran FPPS clones of either type yielded only partial complementation, suggesting unusual catalytic features and/or requirements of these enzymes. Although a structural analysis of lepidopteran FPPS active sites suggested that type-I enzymes are better suited than type-II for generating ethyl-substituted products, a quantitative real-time PCR assessment of their relative abundance in insect tissues indicated that type-I expression is ubiquitous whereas that of type-II is essentially confined to the JH-producing glands, where its transcripts are ∼20 times more abundant than those of type-I. These results suggest that type-II FPPS plays a leading role in lepidopteran JH biosynthesis in spite of its apparently more conventional catalytic cavity [less ▲]
