Isolation from bovine cotyledon extracts of an hormone with somatotrophic and mammotrophic activity was performed using this hormone during the successive steps of purification, its prolactinic and somatotrophic activity was determined by radioreceptor assay. The purified hormone shows a prolactinic activity similar to that of PRL-NIH-B4 standard and a somatotrophic activity three times that of GH-NIH-B18 standard. [less ▲]

Three quaternary alkaloids have been isolated from root barks of STRYCHNOS USAMBARENSIS Gilg from Rwanda: malindine, isomalindine and Nb-methyl-antirhine. The structure elucidation and the stereochemistry of the new isomalindine has been proposed based on its spectral data and their comparison with those of malindine, its isomer. [less ▲]

Equine bone gamma-carboxyglutamic acid containing protein - also called osteocalcin - has been isolated for the first time till homogeneity. After acid demineralisation and acid extraction, the purification procedure was based on reverse phase chromatography, gel filtration and ion exchange chromatography. The amino acid sequence of the primary structure has been determined to be YLDHWLGA(HYP) APYPDPL(GLA)PRR(GLA)VC (GLA)LNPDCDELADHIGF-AYRRFYGPV. The protein has a calculated molecular weight of 5,732 kDa and a calculated isoelectric point of 4,45. It contains 49 amino acids, from which 3 are gamma-carboxyglutamic acid residues at position 17, 21 and 24 and has a fully hydroxylated proline in position nine and cysteine in position 23 and 29. Equine osteocalcin shows a strong homology with bovine (98%), ovine (96%) and human (94%) osteocalcin [less ▲]

The structure and the stereochemistry of afrocurarine (a new unsymmetrical bisindole alkaloid) previously isolated from S. USAMBARENSIS Gilg. are established especially from (1)H-NMR spectroscopic data. The separation of quaternary alkaloids has always been very tedious. Ion-pair reversed-phase column chromatography applied to the purification of afrocurarine is proved very useful and seems to be a suitable technique in quaternary alkaloid research. [less ▲]

Fluorocurarine is isolated from the root barks of Strychnos usambarensis by Droplet Counter Current Chromatography (DCCC), a new technique of liquid/liquid chromatography. This quaternary alkaloid (previously identified in curare and South-Amercican Strychnos) is found for the first time in an African Strychnos. MS, CD, 1H and 13C NMR data are also provided. [less ▲]

L’isolement social en Belgique touche aujourd’hui 23% des 65 ans et plus. Ce phénomène, contrairement à certaines croyances, ne semble pas s’aggraver, mais le vieillissement rapide de notre population laisse présager une augmentation de la prévalence des personnes âgées isolées dans les années à venir. Cet article vise à établir la prévalence de l’isolement social en Belgique en 2011, identifier ses déterminants et analyser l’évolution temporelle de la solitude, la forme subjective de l’isolement social.
