The Large Offspring Syndrome has frequently been reported for in vitro produced calves. The objective of this study was to determine whether any differences in body dimensions (biparietal diameter of the cranium (BPD), cross-section of the abdomen at the insertion of the umbilical cord (CAU)) and heart rate (FHR) can be detected during the first 108 days of gestation between bovine foetuses derived from different methods of embryo production. Three groups of pregnancies with calvings at term resulted from non-surgical transfers of three types of embryos: recipients carrying an embryo obtained by standard MOET procedures (n = 25); recipients carrying an embryo produced in vitro from OPU-derived oocytes, using co-culture-medium (n = 14) or SOF-medium (n = 22). Transrectal ultrasonographic examinations were performed weekly. Ultrasound images were recorded and during off-line analysis FHR, BPD and CAU were determined. For each foetus a curve was fitted and the estimates on fixed time intervals were used as dependent variables in an analysis of variance to detect differences between the three pregnancy groups. Neither gestation length nor birth weight differed significantly between the three pregnancy groups, nor could any differences with respect to BPD, CAU or FHR be detected between Days 35 and 108 of gestation. It is concluded that no differences exist between the early development of bovine foetuses, derived from MOET, IVP-co-culture or IVP-SOF embryos, and resulting in calves with normal birth weights.

La nuit du 3 au 4 août 1312, la collégiale Saint-Martin est livrée aux flammes, condamnant à une mort certaine les Patriciens de la Cité qui y avaient trouvé refuge. Cet incendie demeure dans la mémoire liégeoise, le violent symbole du coup d’arrêt des prétentions de domination des « petits » par les « grands » non sans susciter nombre d’interrogations quant aux raisons et motivations de ce geste assassin. Les incendiaires ne pouvaient n’avoir mesuré l’ampleur des conséquences de leur acte ; l’incendie volontaire était, depuis l’Antiquité, considéré au nombre des crimes les plus graves. Ravageur et destructeur, le feu était aussi purificateur, tant pour les métaux précieux que pour les âmes. C’est à cette double nature paradoxale du feu – symbole de pureté, de perfection autant que de malheur et de destruction –, à son action redoutable, à son image et à sa symbolique juridique et spirituelle au haut moyen âge et au moyen âge central qu'était consacrée cette communication.

Based on an original interpolation method we develop a beam finite element formulation on the Lie group SE(3) which relies on a mathematically rigorous framework and provides compact and generic notations. We work out the beam kinematics in the SE(3) context, the beam deformation measure and obtain the expression of the internal forces using the virtual work principle. The proposed formulation exhibits important features from both the theoretical and numerical points of view. The approach leads to a natural coupling of position and rotation variables and thus differs from classical Timoshenko/Cosserat formulations. We highlight several important properties such as a constant deformation measure over the element, an invariant tangent stiffness matrix under of rigid motions or the absence of shear locking.

These brief remarks (originally made as a panel member commenting on other speaker's views) touch on two elementary questions regarding representative actions envisaged in the Commission's White Paper on Damages Actions for Breach of the EC antitrust rules. The first question adressed is "who will represent whom?". On this aspect, an analogy is drawn with the proposed directive on access to justice in environmental law matters. The second issue concerns conflicting preferences of consumers and corporate defendants regarding publicity of proceedings in which consumer's claims for damages are adjudicated. [less ▲]

BACKGROUND: In the Netherlands and Belgium, an increasing number of children who have end-stage renal disease (ESRD) are of non-Western origin. We analysed renal transplantation practices and outcome for immigrant ESRD children as compared to native children in both countries. METHODS: All Dutch and Belgian children aged <19 years who received their first renal transplantation between 1 September 2007 and 1 January 2011 were included. Therapy characteristics and outcomes were registered prospectively on a 3-monthly basis. Immigrants were defined as children of whom one or both parents had been born outside Western European countries. Multivariable Cox regression analysis was used to quantify the hazard ratio for acute rejection. RESULTS: One hundred and nineteen first renal transplant recipients were included, of which 41 (34%) were immigrants. Median [range] follow-up time of transplantation was 18 [2-28] months. Compared to native children, immigrants had pre-emptive transplantations (15 versus 32%, P = 0.040) and transplantations with a kidney from a living donor less often (24 versus 59%, P < 0.001). Survival analysis in 96 children with at least 3 months of follow-up showed an increased risk for acute rejection in immigrants adjusted for donor source, duration of dialysis and number of HLA mismatches on the DR locus [hazard ratio (95% confidence interval) 2.5 (1.1-5.9)]. CONCLUSIONS: Immigrant children receive fewer pre-emptive and living donor transplantations compared to native children. After transplantation, immigrant children are at higher risk for acute rejection irrespective of the mode of transplantation. [less ▲]

Objective: In experimental animals, recent results suggest that the addition of inulin-type fructans such as oligofructose (OFS) in the diet decreases triacylglycerol accumulation in the liver tissue. Therefore, we have investigated the effect of daily ingestion of OFS in seven patients with nonalcoholic steatohepatitis (NASH), confirmed by liver biopsies. Design: They received 16 g/day OFS or maltodextrine (placebo) for 8 weeks in a randomized double-blind crossover design. Energy intake, body composition, liver steatosis and blood parameters were analysed after 4 and 8 weeks of dietary supplementation. Results: Compared to placebo, OFS decreased significantly serum aminotransferases, aspartate aminotransferase after 8 weeks, and insulin level after 4 weeks, but this could not be related to significant effect on plasma lipids. Conclusion: This pilot study supports the putative interest of OFS in the management of liver diseases associated with abnormal lipid accumulation in humans. [less ▲]

Cranial cartilage derives mainly from cranial neural crest cells and its formation requires fibroblast growth factor (Fgf) signaling for early differentiation and survival of developing chondrocytes as well as patterning of the endodermal pouches. Here, we investigate the role of Fgf receptors in chondrocyte maturation at later stages, beyond 24hpf. Using inducible expression of a dominant-negative Fgf receptor, we show that Fgf signaling is required around 30hpf for correct cartilage formation. The receptor genes fgfr1a and fgr2 are expressed in pharyngeal endodermal pouches after 24hpf or 26hpf, respectively. Depletion of any of these two receptors by microinjection of antisense morpholinos results in severe defects in cartilage formation at 4dpf and a decrease in expression of the late chondrocyte markers barx1 and runx2b. Although endodermal pouches are correctly formed and patterned, receptor knock down leads to decreased expression of runx3, egr1 and sox9b in this tissue, while expression of fsta, coding for a secreted BMP/Tgfss inhibitor, is clearly increased. Rescue experiments revealed that each Fgfr1a or Fgfr2 receptor is able to compensate for the loss of the other. Thus, we show that minimal amounts of Fgfr1a or Fgfr2 are required to initiate a regulatory cascade in pharyngeal endoderm reducing expression of fsta, thereby allowing correct BMP signaling to the maturing chondrocytes of the head cartilage.

Fibroblast Growth Factors 3 (FGF-3) and 4 (FGF-4) were compared for the effects they each exert on EF43 mouse cells. This non-transformed mammary cell line appears to be myoepithelial mainly because it expresses alpha-smooth muscle actin. The EF43 cells were infected with similar vectors that carry either the short fgf-3 sequence (the product of which goes into the secretory pathway), fgf-4 or the selection gene only as control. In syngeneic animals, EF43.fgf-3 cells were tumorigenic only when orthotopically implanted whereas EF43.fgf-4 cells invariably gave rise to aggressive tumors. However, both tumor types were metastatic as evidenced by the blue micrometastases observed when the implanted cells expressed lacZ. In vitro, the FGF-3 producing cells were strongly invasive in matrigel coated chambers whereas the EF43.fgf-4 cells only were invasive in type I-collagen gels. Interestingly, FGF-3 production greatly stimulated the synthesis of pro-MMP-9 (Matrix Metalloprotease-9) and, to a lesser extent, that of pro-MMP-2. FGF-3 also up-regulated the production of plasminogen activators. In contrast, FGF-4 had no effect on these secretions and the medium conditioned by the EF43.fgf-4 cells displayed the largest plasminogen activator-inhibitor activity. These results show that FGF-3 and FGF-4 have distinct mechanisms of action on myoepithelial cells. [less ▲]

In many types of cancers, the fragile histidine triad (Fhit) gene is frequently targeted by genomic alterations leading to a decrease or loss of gene and protein expression. Fhit has been described as a tumor suppressor gene because of its ability to induce apoptosis and to inhibit proliferation of tumor cells. Moreover, several studies have shown a correlation between the lack of Fhit expression and tumor aggressiveness, thus suggesting that Fhit could be involved in tumor progression. In this study, we explored the potential role of Fhit during tumor cell invasion. We first showed that a low Fhit expression is associated with in vivo and in vitro invasiveness of tumor cells. Then, we showed that Fhit overexpression in Fhit-negative highly invasive NCI-H1299 cells by transfection of Fhit cDNA and Fhit inhibition in Fhit-positive poorly invasive HBE4-E6/E7 cells by transfection of Fhit small interfering RNA induce, respectively, a decrease and an increase in migratory/invasive capacities. These changes in cell behavior were associated with a reorganization of tight and adherens junction molecules and a regulation of matrix metalloproteinase and vimentin expression. These results show that Fhit controls the invasive phenotype of lung tumor cells by regulating the expression of genes associated with epithelial–mesenchymal transition. [less ▲]
