This article deals with a study realized amongst siblings whose gaps in age were different. It attempts to bring out the whole importance of this variable to the development of the siblings, considered in its « normality ». It notably points out how the intensity of the differences between full siblings of the same sex and with a small gap in age can be understood (indeed, sisters and brothers who are close in age and of the same sex, particularly amongst siblings of two, often appear to be very different and complementary). But this article also shows how the mark of the intrusion is different according to the age of the elder during this intrusion and how the impact of this variable (which is yet so little studied) seems to be significant in the individuals’development, on the narcissistic level as much as in the affects management.

BACKGROUND/AIMS: Beyond subjective assessments, the effect of skin tensors is difficult to assess. The present 2-phase randomized double-blind split face study was designed to compare the effect of a gel containing 3% 2-dimethylaminoethanol (deanol, DMAE) with the same formulation without DMAE. METHODS: In a first pilot study, sensorial assessments and measures of the skin distension under suction were performed in eight volunteers. In a second study conducted in 30 volunteers, shear wave propagation was measured. RESULTS: Large interindividual variations precluded any significant finding in the first study. The DMAE formulation showed, however, a significant effect characterized by increased shear wave velocity in the direction where the mechanical anisotropy of skin showed looseness. CONCLUSION: The DMAE formulation under investigation increased skin firmness. [less ▲]

Metabolite assays are required to characterise how metabolism changes between genotypes during development and in response to environmental perturbations. They provide a springboard to identify important regulatory sites and investigate the underlying mechanisms. Due to their small size, Arabidopsis seeds pose a technical challenge for such measurements. A set of assays based on a novel enzymic cycling system between glycerol-3-phosphate dehydrogenase and glycerol-3-phosphate oxidase have been developed and optimised for use with growing Arabidopsis seeds. In combination with existing assays they provide a suite of high throughput, sensitive assays for the immediate precursors for starch (adenine diphosphate glucose) and lipid (acetyl coenzyme A, glycerol-3-phosphate) synthesis, as well as pyrophosphate, ATP, ADP and most of the glycolytic intermediates. A method is also presented to rapidly quench intact siliques, lyophilise them and then manually separate seeds for metabolite analysis. These techniques are used to investigate changes in overall seed metabolite levels during development and maturation, and in response to a stepwise decrease of the external oxygen concentration.

La célébrissime Chute d'Icare des Musées royaux des Beaux-Arts de Belgique à Bruxelles est considérée comme l’une des œuvres majeures de Pierre Bruegel l'Ancien. Or son état matériel éveille la perplexité : l'œil exercé y repère des anomalies inquiétantes. Son examen technique a été entrepris avec la collaboration de l’IRPA (Bruxelles). L'étude au C14 de la toile du support et celle du dessin sous-jacent par réflectographie infrarouge invitent à y voir une copie réalisée à la fin du XVIe siècle ou au début du XVIIe, probablement d’après un original perdu de Bruegel. Une autre version de la composition est conservée à Bruxelles, au Musée Van Buuren. Injustement éclipsée par celle des Musées royaux des Beaux-Arts de Belgique, elle mérite d’être reconsidérée, même si elle n’est pas non plus due au pinceau de Bruegel. Peinte sur panneau, elle a été datée de la fin du XVIe siècle par dendrochronologie. [less ▲]

Real-time ultrasound data collection, consisting specifically of longissimus thoracis muscle echogenicity, was carried out on 80 Pietrain pigs (42 gilts and 34 barrows) using the Pie Medical scanner 200 equipped with an ASP-18 probe and 3.5 MHz to predict intramuscular fat. Two ribs thickness (12th and 13th ribs) was excised from the longissimus thoracis muscle for subsequent ether extract value (EE) determination. The percentage of white pixels in the ultrasound image were related to EE percentage. The EE percentages were 1.44, 1.37 and 1.15 % respectively for the homozygous stress-negative Pietrain (CC), heterozygous stress-negative Pietrain (CT) and homozygous stress-positive Pietrain (TT) individuals. The percentage of white pixels in the longissimus thoracis images were 9.98, 8.75 and 7.79 % respectively for CC, CT and TT genotypes. The barrows had an higher intramuscular fat and white pixel percentage than the gilts. The determination coefficient (R 2) of the EE prediction model originating from the white pixels percentage was 0.35 with a root mean squared error of 0.26 %. These performance could be potentially improved using the calibration phantom of the ASP-18 probe, before taking images. [less ▲]

BACKGROUND: It is now well established that after conventional allogeneic hematopoietic stem-cell transplantation (HSCT), erythropoietic recovery is impaired because erythropoietin (Epo) production remains inadequate for prolonged periods of time. However, erythropoietic reconstitution after nonmyeloablative SCT (NMSCT) has never been characterized. METHODS: Twelve patients received a nonmyeloablative conditioning regimen consisting of 2 Gy total body irradiation (TBI) alone (n=6), 2 Gy TBI and fludarabine (n=3), or cyclophosphamide and fludarabine (n=3), followed by transplantation of allogeneic peripheral blood stem cells. Graft-versus-host-disease (GvHD) prophylaxis was carried out with mycophenolate mofetil (from day -1 to day 28) plus cyclosporine (from day -1 to day 120 or longer in case of chronic GvHD). Erythropoiesis was quantitated by soluble transferrin receptor (sTfR) levels, and the adequacy of Epo production was evaluated by the observed-to-predicted Epo ratio (O/P Epo). RESULTS: Mean sTfR levels decreased following the conditioning regimen but remained well within the normal range throughout the posttransplant period. The O/P Epo ratio presented an initial surge quite similar to that observed after conventional conditioning. Thereafter, the O/P Epo ratio normalized rapidly, and Epo levels remained adequate during the whole observation period. CONCLUSION: Contrarily to what is observed after myeloablative transplant, Epo levels remained adequate after NMSCT, resulting in normal erythropoiesis. These results suggest that the administration of erythropoietin therapy (rHuEpo) could be less effective after NMSCT than after conventional allogeneic transplant. [less ▲]

Crystals of Ba2FeO4 and Ba3FeO5, grown from a "self-sealing" KOH-Ba(OH)(2) flux, have been characterized by single-crystal X-ray diffraction, Mossbauer spectroscopy, and magnetic measurements. Ba2FeO4 forms nonmerohedral twinned crystals with the monoclinic space group P2(1)/c, a = 6.034(2) Angstrom, b = 7.647(2) Angstrom, c = 10.162(3) Angstrom, beta = 92.931(6)degrees, and Z = 4. Ba3FeO5 crystallizes in the orthorhombic space group Pnma, with a = 10.301(1) Angstrom, b = 8.151(1) Angstrom, c = 7.611(1) Angstrom, and Z = 4. While both compounds feature discrete FeO44- tetrahedra, the anion found in Ba2FeO4 has shorter Fe-O bonds and is significantly distorted relative to the Ba3FeO5 anion, An iron valence of 4+ was confirmed by magnet susceptibility measurements and by the low-temperature isomer shifts of -0.152 and -0.142 mm/s relative to alpha-iron for Ba2FeO4 and Ba3FeO5, respectively.

We report first-principles calculations on the structural properties of SrRuO 3/BaTiO3 (metal/ferroelectric) and BaO/BaTiO3 (insulator/ferroelectric) heterostructures, both of them paradigmatic systems for experimental measurements. Using a density-functional pseudopotential plane-wave method, as implemented in the ABINIT package, we have studied the changes in the interlayer spacing and the atomic rumpling. The substrates are explicitly considered in our simulations, so the lateral stress on the BaTiO3 thin films and mechanical boundary conditions are automatically taken into account. For the SrRuO3/BaTiO3 interface short-circuit boundary conditions are imposed. Results on free-standing BaTiO3 surfaces are also reported, showing good agreement with previous works. The ground state for all the structures studied here is paraelectric. [less ▲]

Micro-organisms of the genus Bifidobacterium are some of the most common micro-organisms in the human and animal intestinal tract. Bifidobacterium species are well known for their beneficial effects on the microflora. In this article, the interest for this microorganism is other. If this microorganism is found at different stages of the processing line, it indicates often a contamination of this processing line. An other characteristic is that Bifidobacterium species are different according to the host. It could be possible to determine the contamination origin (human or animal). That is an advantage over other bacteria such as the actual faecal contamination indicator, Escherichia coli. The aim of this project is to develop a test, using molecular genetic tools, to rapidly detect the most important Bifidobacterium species in food. If we know the contamination sources, the critical points will be pointed out and the control measures will be better. [less ▲]
