The ring-opening metathesis polymerization (ROMP) of two optically active 2,3-dicarboalkoxynorbornadienes derived from (S)-(-)-2-methyl-1-butanol and (R)-(-)-2-butanol were carried out in the presence of the [RuCl2(P-cymene)](2) catalyst precursor activated by trimethylsilyldiazomethane (TMSD). H-1 and C-13 NMR analyses showed that a high degree of stereoregularity was achieved, and homonuclear proton-proton COSY spectroscopy indicated that the major trans fractions of the polymers were most likely isotactic, while the minor cis fractions were syndiotactic. Ring-opened metathesis polymers were also made from 2,3-dicarbomethoxynorbornadiene and exo,exo-2,3-dicarbomethoxy-5-norbornene. They were hydrogenated into the corresponding polynorbornanes using diimide. The NMR spectra of the reduced materials confirmed that the unsaturated parent polymers had an all-trans highly isotactic microstructure. A tentative mechanism involving arene loss, carbene formation, and monomer chelation is proposed to account for the observed stereoselectivities. [less ▲]

Two ternary systems of fats were studied. In the first system, low-erucic acid rapeseed oil (LERO), hydrogenated low-erucic acid rapeseed oil (HLERO), and palm oil (PO) were blended. In the second system, hydrogenated palm oil (HPO) was used instead of PO and was blended with LERO and HLERO. The blends were then studied for their physical properties such as solid fat content (SFC), melting curves by DSC, and polymorphism (X-ray). HPO showed the highest melting enthalpy after 48 h at 15degreesC (141 +/- 1 J/g), followed by HLERO (131 +/- 2 J/g), PO (110 +/- 2 J/g), and LERO (65 +/- 4 J/g). Binary phase behavior diagrams were constructed from the DSC and X-ray results. Iso-line diagrams of partial-melting enthalpies were constructed from the DSC results, and binary and ternary isosolid diagrams were constructed from the NMR results. The isosolid diagrams demonstrated formation of a eutectic along the binary blend of PO/HLERO. However, no eutectic effect was observed along the binary lines of HPO/HLERO, PO/LERO, HPO/LERO, or HLERO/LERO. The same results were found with the iso-line diagrams of partial-melting enthalpies. As expected, addition of PO or HPO increased polymorphic stability in the beta' form of the HLERO/LERO mixture. [less ▲]

Animal productions are the results of interactions between the genetic potential of the animal, environmental factors and nutrient supplies. These interactions modulate the endocrine system, especially the somatotrope axis. IGFBP-3 is the major carrier of the IGFs (the main growth-promoting peptide) in plasma circulating as part of a 150 kDa ternary complex with one IGF peptide and a single acid-labile subunit. The IGFBP-3 purification would allow the measure of the changes in plasma IGFBP-3 throughout the day and the development and in various physiological situations. We try to purify the bovine IGFBP-3. Firstly, we load 0,5 ml of serum onto an Hiload 16/6 Superdex 200 prep grade column, then onto an ion exchange column and finally onto an IGF-I affinity column. The purification fails perhaps because the sample is to small. Secondly, 5 ml of serum is fractionated by 3 gel filtrations. Between the first and the second filtration, the fractions containing IGF-I binding activity are pooled and concentrated. Before the third gel filtration, the fractions containing this activity are pooled anew, acidified with HCl and incubated at 4 °C for 2 hours. The third gel filtration fractions are pooled and subjected to an heparin-affinity chromatography. The elution pic shows only IGFBP-3 activity. In conclusion, our purified product contains other proteins. But the ternary complex is dissociated, so an IGF-I affinity chromatography would purify the IGFBP-3 from the elution pic of the heparin-affinity column. [less ▲]

Our ability to recognise the usual horizontal orientation Of Our own face (mirror orientation) as compared with another very familiar face (normal orientation) was examined in experiment 1. Participants did not use the same kind of information in determining the orientation of their own face as in determining the orientation of the other familiar face. The proportion of participants who reported having based their judgment on the location of an asymmetric feature (eg a mole) was higher when determining the orientation of their own face than when determining that of the other familiar face. In experiment 2, participants were presented with pairs of manipulated images of their own face and of another familiar face showing conflicting asymmetric features and configural information. Each pair consisted of one picture showing asymmetric features of a given face in a mirror-reversed position, while the facial configuration was left unchanged; and one picture in which the location of the asymmetric features was left unchanged, while the facial configuration was mirror-reversed. As expected from the hypothesis that asymmetric local features are more frequently used for the judgment of one's own face, participants chose the picture showing mirror-reversed asymmetric features when determining the usual orientation of their own face significantly more often than they chose the picture showing normally oriented asymmetric features when determining the orientation of the other face. These results are explained in terms of competing forward and mirror-reversed representations of one's own face. [less ▲]
