The aim of this study was to investigate the influence of isoenergetic substitution between the three energy delivering macronutrients in pre-starter diets on performance and intermediary nutrient metabolism in broiler chickens. From hatch until 5 days of age, 600 chicks, collected during peak of hatch, were fed one of the three experimental pre-starter diets with isoenergetic (13 MJ metabolisable energy/kg) substitutions between fat (43 vs. 108 g/kg), protein (126 vs. 240 g/kg) and carbohydrates (391 vs. 510 g/kg). After 5 days, commercial grower and finisher diets were provided. Pre-starter composition influenced body weight until slaughter age, although not statistically verifiable. Broilers fed the low protein (LP) pre-starter had the lowest body weight in relation to chickens on the low carbohydrate or low fat pre-starter diet. After hatch, chicks on the LP pre-starter diet were able to use the residual yolk sac more rapidly to fulfil their protein requirement, which is reflected in small intestine and liver development. Also, plasma metabolite levels were influenced mostly by the LP pre-starter, indicating that the main focus for the requirements of newly hatched chicks should be on proteins. Furthermore, optimal nutrition during the first day's post-hatch should take into account the contribution of the yolk. [less ▲]

L’étude des cultes isiaques dans la péninsule Ibérique donne à connaître une série de documents qui représentent un pied sous sa forme réelle ou gravé sur des stèles votives. Se pose alors la question de l’origine de ce symbole. Apparenté aux divinités égyptiennes, il est synonyme de richesse et d’abondance dans la religion pharaonique. À partir de la vallée du Nil, les deux modèles se sont diffusés dans le monde méditerranéen et ils ont atteint l’Hispanie au IIe siècle en passant sans doute par le continent africain. Sans aucune référence dans la littérature antique, l’enquête menée autour de ces représentations et de leurs différentes déclinaisons n’autorise pas à leur attribuer une seule signification. Les pieds de Sérapis comme les stèles dédiées à Isis incarnent le plus souvent l’épiphanie divine, mais ils peuvent également être considérés comme de simples témoignages de dévotion. Lorsque les empreintes de pieds correspondent à celles de la déesse et que les stèles sont situées devant l’entrée du temple, elles pourraient faire référence à un rituel d’accueil. [less ▲]

In linear models for hedge fund returns, errors-in-variables may significantly alter the measurement of factor loadings and the estimation of abnormal performance. The higher moment estimator (HME) introduced by Dagenais and Dagenais (1997) effectively deals with these issues. Results on individual funds show that the HME specification does not uncover systematic performance biases, but can modify estimated alphas in most cases and identifies relative persistence for directional funds in bearish market conditions. Overall, the risk premia calculated with HME remain relatively stable when compared to ordinary least squares specifications. [less ▲]

The global financial crisis of year 2009 is explained as a result of uncoordinated risk management decisions in business firms and economic organisations. The underlying reason for this can be found in the current financial system. As the financial market has lost much of its direct coupling to the concrete economy it provides misleading information to economic decision makers at all levels. Hence, the financial system has moved from a state of moderate and slow cyclical fluctuations into a state of fast and chaotic ones. Those misleading decisions can further be described, but not explained, by help of adaptive and rational expectations from macroeconomic theory. In this context, AE, the Adaptive Expectations are related to weak passive Exo-anticipation, and RE, the Rational expectations can be related to a strong, active and design oriented anticipation. The shortcomings of conventional cures, which builds on a reactive paradigm, have already been demonstrated in economic literature and are here further underlined by help of Ashby's “Law of Requisite Variety”, Weaver's distinction between systems of “Disorganized Complexity” and those of “Organized Complexity”, and Klir's “Reconstructability Analysis”. Anticipatory decision-making is hence here proposed as a replacement to current expectation based and passive risk management. An anticipatory model of the business cycle is presented for supporting that proposition. The model, which is an extension of the Kaldor-Kalecki model, includes both retardation and anticipation. While cybernetics with the feedback process in control system deals with an explicit goal or purpose given to a system, the anticipatory system discussed here deals with a behaviour for which the future state of the system is built by the system itself, without explicit goal. A system with weak anticipation is based on a predictive model of the system, while a system with strong anticipation builds its own future by itself. Numerical simulations on computer confirm the feasibility of this approach. Hence, functional differential equations with both retardation and anticipation are found to be useful tools for modelling financial systems. [less ▲]

Randomised controlled trials play a key role in evidence-based medicine as far as the assessment of both efficacy and safety of drugs is concerned. Various strategies are used to avoid physician's inertia and to combat patient's non compliance, two pitfalls that may hinder the demonstration of the therapeutic efficacy of the drug. Clinical inertia may be limited by titration, forced or optional, driven by therapeutic targets, or by the use, if necessary, of rescue medications. Compliance may be verified by "pill count". This simple technique allows to exclude non compliant patients when they are detected during the placebo run-in period before randomisation or not to take into account patients with poor compliance in the final evaluation by using a statistical analysis restricted to individuals who have strictly adhered to the study protocol ("per protocol analysis"). Self-monitoring and patient's empowerment in the treatment also contribute to improve drug compliance. Clinicians may take advantage of these approaches derived from clinical trials to improve their daily practice. [less ▲]

Assessment of daily living activities is essential in patients with Alzheimer's disease. Most current tools quantitatively assess overall ability but provide little qualitative information on individual difficulties. Only a few tools allow therapists to evaluate stereotyped activities and record different types of errors. We capitalised on the Kitchen Activity Assessment to design a widely applicable analysis grid that provides both qualitative and quantitative data on activity performance. A cooking activity was videotaped in 15 patients with dementia and assessed according to the different steps in the execution of the task. The evaluations obtained with our grid showed good correlations between raters, between versions of the grid and between sessions. Moreover, the degree of independence obtained with our analysis of the task correlated with the Kitchen Activity Assessment score and with a global score of cognitive functioning. We conclude that assessment of a daily living activity with this analysis grid is reproducible and relatively independent of the therapist, and thus provides quantitative and qualitative information useful for both evaluating and caring for demented patients.

In this study, a cell based lattice free modelling framework is proposed to study cell aggregate behaviour in bone tissue engineering applications. The model encompasses cell-to-cell and cell environment interactions such as adhesion, repulsion and drag forces. Oxygen, nutrients, waste products, growth factors and inhibitors are explicitly represented in the model influencing cellular behaviour. Furthermore, a model for cell metabolism is incorporated representing the basic enzymic reactions of glycolysis and the Krebs cycle. Various types of cell death such as necrosis, apoptosis and anoikis are implemented. Finally, an explicit model of the cell cycle controls the proliferation process, taking into account the presence or absence of various metabolites, sufficient space and mechanical stress. Several examples are presented demonstrating the potential of the modelling framework. The behaviour of a synchronised cell aggregate under ideal circumstances is simulated, clearly showing the different stages of the cell cycle and the resulting growth of the aggregate. Also the difference in aggregate development under ideal (normoxic) and hypoxic conditions is simulated, showing hypoxia induced necrosis mainly in the centre of the aggregate grown under hypoxic conditions. The next step in this research will be the application of this modelling framework to specific experimental set-ups for bone tissue engineering applications. (C) 2009 Elsevier Ltd.
