Porcine PAG (pPAG) are placental products of a multigene family that is strongly expressed in the chorionic epithelium (trophoblast and trophectoderm). The objective of this study was to define a pattern of the pPAG proteins, secreted in vitro by chorionic explants harvested on 16-77 days of pregnancy. Trophoblastic and trophectodermal explants were collected from pregnant (PR) gilts (n = 27) and used for protein in vitro production (8-261 h). Endometrial explants of luteal-phase gilts (E10, n = 4) and pseudopregnant gilts (PsE, n = 2) were used as negative controls for protein immunoblotting. Proteins (PR, E10, PsE) were isolated mainly from incubation media, fractionated, dialysed and separated by SDS-PAGE. Heterogeneous Western blotting with various polyclonal anti-PAG sera raised against bovine or ovine antigens (anti-bPAG, or anti-oPAG) initially identified the pPAG proteins. Such blotting of fractionated chorionic proteins allowed for the isolation of porcine antigens that were employed as immunogens to raise several homologous antisera (anti-pPAG). Crude antisera were adsorbed on endometrial extracts or proteins of non-PR pigs, to remove non-relevant antibodies. The patterns of pPAG proteins secreted in Vitro varied throughout pregnancy (35-72 kDa). During implantation, similar to43 kDa (Day 16) or similar to68.1 kDa (Days 17-25) pPAG proteins were detected. During placentation and as pregnancy advanced (Days 31-77), similar to72.3 kDa pPAG proteins were observed. The secretions of parallel multiple smaller proteins (35.4-47.2 kDa), presumably, as forms of processed pPAG precursors, increased with the progress of gestation. In conclusion, the pPAG protein family plays a very important role during implantation, placenta formation and embryonic/foetal development in the pig. [less ▲]

A new transition-metal-containing Zintl compound, Eu10Mn6Sb13, was prepared by a high-temperature Sn-flux synthesis. The structure was determined by single-crystal X-ray diffraction. Eu10Mn6Sb13 crystallizes in the monoclinic space group C2/m with a = 15.1791(6) Angstrom, b = 19.1919(7) Angstrom, c = 12.2679(4) Angstrom, beta = 108.078(1)degrees, Z = 4 (R1 = 0.0410, wR2 = 0.0920), and T = 90(2) K. The structure of Eu10Mn6Sb13 is composed of double layers of Mn-centered tetrahedra separated by Eu2+ cations. The double layers are composed of edge- and corner-sharing Mn-centered tetrahedra which form cavities occupied by Eu2+ cations and [Sb-2](4-) dumbbells. Linear [Sb-3](5-) trimers bridging two tetrahedra across the cavity are also present. Bulk susceptibility data indicate paramagnetic behavior with a ferromagnetic component present below 60 K. Temperature-dependent electrical resistivity measurements show semiconducting behavior above 60 K (E-a = 0.115(2) eV), a large and unusually sharp maximum in the resistivity at similar to40 K, and metallic behavior below 40 K. Eu-151 Mossbauer spectra confirm that the europium is divalent with an average isomer shift of -11.2(1) mm/s at 100 K; the spectra obtained below 40 K reveal magnetic ordering of six of the seven europium sublattices and, at 4.2 K, complete ordering of the seven europium sublattices.

This present research aims to compare physical and mechanical characteristics between two larch species and their hybrid (Larix decidua Mill., Larix kaempferi (Lambert) Carr. et Larix x eurolepis Henry). From each species, normalised samples have been sawn from five trees, and <br />submitted to normalised tests according to the norms NBN 225, NF B 51-016 and DIN 52189. The Japanese (Larix kaempferi (Lambert) Carr.) and hybrid (Larix x eurolepis Henry) larches present similar physical and mechanical properties, always lower than those observed for the European one. This is partly explained by a higher mean wood density for this species. <br />Whatever the species, juvenile wood presents lower physical and mechanical properties than mature wood. The larch wood produced in the Walloon Region presents a large technological potential that it is interesting to promote, without forgetting to adapt the classification procedures. Consequently, larch appears to be a versatile species, which can be used for numerous purposes, inside as well as outside. [less ▲]

Le principal objectif visé par le présent travail est de mettre au point des catayseurs efficaces, capables de polymériser par voir radicalaire contrôlée des oléfines internes (peu réactionnelles) et, plus particulièrement, l'huile de lin.Nous tenterons aussi d'aborder la copolymérisation de l'huile de lin avec des monomères de grande consommation (styrène et (méth)acrylates) afin de mettre au point, au départ d'un produit naturel et renouvelable, des matériaux nouveaux. L'huile de lin est constituée d'un mélange complexe de triglycérides dont les chaînes pendantes sont porteuses de 2 ou 3 liaisons C=C doubles. Face à la diversité et à la complexité structurale de ces molécules, il nous parait évident d'aborder le problème de manière plus systématique en nous basant sur l'étude de la polymérisation d'oléfines internes et/ou fonctionnalisées qui serviront de "modèles" pour celles rencontrées dans l'huile de lin. Nous sommes en effet convaincus que la réussite de ce projet passe avant tout par une bonne compréhension des facteurs qui gouvernent la réactivité des oléfines internes et fonctionnalisées. Ce projet est réalisé dans le Laboratoire de Chimie Macromoléculaire et de Catalyse Organique (CERM) de l'Université de Liège en partenariat avec l'Institut des Sciences de Matériaux (ICMAB, Barcelone) et la Société Vandeputte (Belgique [less ▲]
