A method is described for the purification of canine prolactin, involving preparative isoelectrofocusing. Canine prolactin has a molecular weight of 23 000 daltons, an isoelectric point of 5.7 and exhibits a high degree of homogeneity in polyacrylamide gels stained by means of a silver method. A specific, homologous radioimmunoassay is described using the Bolton-Hunter method for preparation of the labelled ligand, with a sensitivity of 1.1 ng/tube. Basal plasma prolactin levels of 2-4 ng/ml obtained through the oestrous cycle remained fairly constant but a rise of 9 ng/ml was found at the end of disoetrus in nonpregnant bitches. Level also rose 30 days after mating to reach a peak of about 50 ng/ml near parturition and during early lactation. [less ▲]

Insulin-like growth factor-I and -II (IGF-I, IGF-II) circulate in biological fluids bound to six different IGF-binding proteins that regulate IGF bioactivity. The IGF-binding protein-2 is regulated by growth hormones, and its concentration depends on nutrition and physiological state. Specific antibodies directed against bovine IGF-binding protein-2 were produced, and IGF-binding protein-2 levels in bovine blood samples were quantified by radioimmunoassay. Parallel displacement curves showed strong cross-reactivity with bovine and ovine plasma, were low with porcine plasma, and no cross-reactivity with rat or chicken plasma. Addition of IGF-I or -II to a control pool of bovine plasma did not significantly alter control IGF-binding protein-2 values in a radioimmunoassay. Six nycthemeral periods, determined for three young bulls bled on two occasions, showed that IGF-binding protein-2 plasma levels were stable throughout the day; two or three samples were sufficient to characterize the animal. Cows treated with recombinant bovine somatotropin (bST) had significantly lower serum levels of IGF-binding protein-2 than did control cows. Furthermore, IGF-binding protein-2 levels were dramatically increased at the onset of lactation. This radioimmunoassay for bovine IGF-binding protein-2, which enables quantitative assessment of IGF-binding protein-2 concentration in cattle, confirmed that IGF-binding protein-2 concentrations are depressed by administration of bST, enhanced after calving, and showed absence of diurnal variation.

Homologous recombinant tilapia growth hormoe was tested for its effect on calcium metabolism in freshwater tilapia Oreochromis mossambicus. A comparison of the role of GH and prolactin in calcium regulation of the tilapia led to the conclusion that GH has specific calciopropic effects on freshwater Tilapia that differ from those of prolactin.

Melatonin is a neurohormone synthesized and secreted mainly during the dark period of the circadian cycle by the pineal gland. It has already been proved to be involved in a number of chronobiological processes, most of them being mediated by its membranar receptors MT1 and MT2. Both are members of the GPCR class and, despite the interest they elicit, their 3D structure is still to be described. Models for both human MT1 and MT2 receptors have been constructed by homology modeling, using the X-ray structure of bovine rhodopsin as template. These models have been evaluated in terms of hydrophobic properties of the helices and refined to take into account the rearrangement of GPCRs necessary for their activation, thus leading to a putative activated model for each subtype.

Since its discovery, 5-hydroxytryptamine, more usually called serotonin, has been an elusive candidate as a major mood regulator. This capacity gives it a great importance in the treatment of depression. It is within this framework that our work takes place, as it is related more particularly to a new therapeutic class whose leader is agomelatine. This compound binds to the melatoninergic receptors and to the serotoninergic 5-HT2c receptor, giving rise to the MASSA concept (Melatonin Agonist and Selective Serotonin Antagonist). Like the majority of the serotoninergic receptors, the sub-type 5-HT2c is a G-protein coupled receptor (GPCR). The three-dimensional structure of 5-HT2c is not experimentally known, and we thus resorted to comparative homology modelling to build a model allowing us to study its interactions with agomelatine.

Pentenols and pentene dimers are biosynthetized in plants by homolytic fatty acid hydroperoxide lyase (HPL) or HPL-like enzymes. It has been found that these compounds can modify the flavor of olive oil. Reactions between hematin and 13-hydroperoxyoctadecatrienoic acid resulted in the formation of the same compounds via a free radical reaction in which an alkoxyl radical derived from linolenic acid hydroperoxide undergoes a β-scission. (Z)-3-Hexenal has also been detected as a minor product of the reaction. It is bioconversed from the same substrate in plants by heterolytic HPL. Thanks to the redox cycle of its central iron, hematin has both homolytic and heterolytic HPL-like activities. [less ▲]

Various authors like Patterson and Chan (1995) suggest that the psychological evolution of a child who grew up in a homoparental family is not different from that of a child pertaining to other types of family structures. Literature on family dynamics in homoparental contexts (Vecho & Schneider, 2005; Gross, 2005) shows that only few studies focus on a systematic analysis of interactions. They rather deal with representational and symbolic aspects within the parents-children dyad and use various methodological modalities, the analysis unit being the single person. For this reason it is actually essential to try to understand the child’s development from a triadic point of view that takes into consideration the parental couple and the child (Fivaz-Depeursinge, 2003). The aim of our study is to observe the postnatal family interactions of homoparental families using the Lausanne Trilogue Play paradigm (LTP Fivaz-Depeursinge, 1999). We assume that there are no significant differences regarding the quality of the family triadic interactions. Family alliance appears to be comparable in homoparental and other non-referred family samples. The first results with 15 homoparental families seem to confirm our research hypothesis. These pilot results may turn out to be significant in our ongoing research. [less ▲]

Parmi les différentes configurations familiales, la famille homoparentale recomposée est, plus que toute autre, confrontée à de multiples défis. Ceux-ci découlent tant du processus de deuil de la précédente appartenance que de la construction d’une nouvelle famille. Les vicissitudes de ces processus de construction semblent être liées à la gestion des pertes contextuelles pour les enfants comme pour les adultes. Le travail thérapeutique visera à créer un espace de gestion de ces pertes ambiguës entraînant des mouvements d’oscillation affective entre le passé, le présent et le futur. Apprendre à gérer la multiplicité des appartenances et des identités familiales semble être un objectif majeur pour l’intervention avec toute nouvelle famille. [less ▲]
