Performing tensile tests on ECAE material reveals a long post-uniform elongation. In order to calculate correct true stress–true strain diagrams, three different approaches are used: measurements of the actual sample geometry, a neck evolution model proposed by Segal [V.M. Segal, S Ferrasse, F. Alford, Mater. Sci. Eng. A442 (2006) 321–326] and an inverse modelling method by finite element (FE) simulations. [less ▲]

Two-stage liver transplantation, i.e. salvage emergent total hepatectomy with prolonged anhepatic state, and subsequent liver transplantation, has been described as a life-saving procedure in selected cases. The principal drawback of two-stage liver transplantation is the fact that anhepatic patient survival only depends on the future availability of a liver graft. The pathophysiologic alterations induced by total hepatectomy are not fully known, as it is not known how long a patient may be anhepatic before it is too late for hope of survival. In this report the authors describe the cases of three liver recipients who had to undergo salvage liver graft removal early during or after liver transplantation as a life-saving maneuver. All were afterwards registered for emergent liver retransplantation. Mean anhepatic period was 20 hours (Range: 17-24 hours). Two patients survived and fully recovered. From this experience and from other cases reported in the literature, the authors concluded that total hepatectomy may be life-saving in some cases if a liver graft is available in a timely manner.

The expression of at least a third of mammalian genes is post-transcriptionally fine-tuned by approximately 1000 microRNAs (miRNAs), assisted by the RNA silencing machinery, comprising tens of components. Polymorphisms and mutations in the corresponding sequence space (machinery, miRNA precursors and target sites) are likely to make a significant contribution to phenotypic variation, including disease susceptibility. Here we review basic miRNA biology in animals, survey the available evidence for DNA sequence polymorphisms affecting miRNA-mediated gene regulation and thus phenotype, and discuss their possible importance in the determination of complex traits.

The presence of Campylobacter was assessed in different samples of poultry, pork and beef meat and carcasses from slaughterhouses, production plants and retail level. An introductory study from 1997 to 1999, had the purpose of establishing the optimum dilution to detect changes in prevalence and allowed a semi-quantitative estimation of poultry and pork contamination. Following this, between 2000 and 2003, 4254 samples were taken in order to study the trends. The poultry matrixes represented the greatest number and the most highly contaminated samples, with 30.9% (in 0.01 g) positive samples, 18.7% (in 1 g), 46.9% (in 25 g) and 19.6% (in 0.01 g) for broiler carcasses, broiler fillets, prepared chicken and layer carcasses, respectively. Broiler carcasses and fillets sampled at retail level were significantly less contaminated than samples from production plants. Pork, beef and veal samples were rarely contaminated and, where contamination existed, it was at a low prevalence (maximum 5.0%). The high and unvarying prevalence of Campylobacter in poultry necessitates the implementation of intervention measures at the primary production level, in addition to methods of minimizing cross-contamination at the processing level. A survey plan in line with the present study could be used in the future to monitor the effects of the planned measures and performance objectives and to follow the evolution of Campylobacter contamination at all stages of the food chain, in accordance with European legislation.

Tension-free sub-urethral tapes have revolutionized the surgical treatment of female stress urinary incontinence for the past decade. The inside-out transobturator approach, developed in our Institution 5 years ago, is currently being utilized worldwide. The technique is simple and reproducible and the incidence of complications is minimized. Stress urinary incontinence cure rates of almost 90% are achieved after a 3-year minimum follow up. These good results have been confirmed in the international literature. [less ▲]

The 16-kDa N-terminal fragment of human prolactin (16K hPRL) is a potent angiostatic factor that inhibits tumor growth in mouse models. Using microarray experiments, we have dissected how the endothelial-cell genome responds to 16K hPRL treatment. We found 216 genes that show regulation by 16K hPRL, of which a large proportion turned out to be associated with the process of immunity. 16K hPRL induces expression of various chemokines and endothelial adhesion molecules. These expressions, under the control of nuclear factor-kappaB, result in an enhanced leukocyte-endothelial cell interaction. Furthermore, analysis of B16-F10 tumor tissues reveals a higher expression of adhesion molecules (intercellular adhesion molecule 1, vascular cell adhesion molecule 1, or E-selectin) in endothelial cells and a significantly higher number of infiltrated leukocytes within the tumor treated with 16K hPRL compared with the untreated ones. In conclusion, this study describes a new antitumor mechanism of 16K hPRL. Because cellular immunity against tumor cells is a crucial step in therapy, the discovery that treatment with 16K hPRL overcomes tumor-induced anergy may become important for therapeutic perspectives.

We consider the motion of a quasi-one-dimensional beam of Bose-Einstein condensed particles in a disordered region of finite extent. Interaction effects lead to the appearance of two distinct regions of stationary flow. One is subsonic and corresponds to superfluid motion. The other one is supersonic and dissipative and shows Anderson localization. We compute analytically the interaction-dependent localization length. We also explain the disappearance of the supersonic stationary flow for large disordered samples. [less ▲]
