The concentrations of pregnancy-associated glycoproteins (PAG) were determined in buffalo cows (Bubalus bubalis) using three different radioimmunoassay (RIA) systems (RIA-497, RIA-706, and RIA-708). Samples (10 mL) were collected by jugular venipuncture from Week 0 until Week 28 of pregnancy (9 females), and from parturition until Week 10 postpartum (13 females). During pregnancy, PAG molecules were detectable at Week 6 using the three aforementioned RIA systems (3.9 ± 1.3 ng/mL, 9.7 ± 1.3 ng/mL, and 9.9 ± 0.7 ng/mL for RIA-497, RIA-706, and RIA-708, respectively). These concentrations increased gradually until Week 28, reaching values of 39.6 ± 4.0 ng/mL (RIA-497), 50.5 ± 11.9 ng/mL (RIA-706), and 68.2 ± 20.8 ng/mL (RIA-708). PAG concentrations determined by RIA-497, RIA-706, and RIA-708 were strongly correlated throughout the entire gestation period, RIA-708 giving the higher concentrations. At parturition, the mean concentrations ranged from 34.9 ± 4.0 (RIA-497) to 84.7 ± 10.6 ng/mL (RIA-708). Thereafter, the concentrations decreased steadily, reaching very low levels (< 1.0 ng/mL) at Week 8 postpartum. In conclusion, PAG concentrations measured by the above three RIA systems showed a profile similar to those previously described in bovine species, with higher concentrations being detected by RIA-706 and RIA-708. However, the patterns of PAG concentrations, studied using the three aforementioned PAG-RIA systems, differed around parturition, with very low levels being observed in the female buffaloes [less ▲]

Reduced vitamins K are acting as cofactors of glutamic carboxylation of procoagulant factors (II, VII, IX and X). The reduction of these vitamins is inhibited by oral anticoagulants. The response to antivitamins K is individual and may change during the treatment of a patient. The determinations of plasmatic vitamin K and acenocoumarol may help to explain the mechanism of a resistance to the anticoagulant therapy. Quantifications of vitamin K1 are realized after liquid-liquid extraction with liquid chromatography and fluorescence detection after post-column reduction. For acenocoumarol, plasma concentration is measured, after liquid-liquid extraction, by liquid chromatograph, with ion trap mass spectrometer detector. [less ▲]

Compromise as a commonsense concept and as an analogical concept: “family likenesses”. A practical epistemological reflection Should we consider the concept of compromise only in the presence of partners willing to negotiate and who both accept to make concessions in order to arrive at some form of agreement? Is it appropriate to talk of compromise when facing abstract entities or categories of opposing ideas? This article explores what would be necessary in order to be able to establish a link between commonsense compromise and analogical compromise, the two accepted meanings of the concept. Its ambition is to construct two operational concepts capable of rendering intelligible the multiple realities of compromise. Starting from the lexical field of the term compromise, an operational theoretical concept is constructed. The compromise is considered from its commonsense perspective and from its varied uses in relation to its different contexts in order to determine its principal specific characteristics. Finally, the concept of grammar is used for identifying what is shared by the two concepts and for establishing the foundations of a reflection on the issue of the social construction of compromise [less ▲]

Purpose: The objective of this paper was to determine the interest and psychometric properties of a new QOL self-assessment questionnaire suitable for children 8 to 12 years old measuring alpha, beta and gamma changes: the “Inventaire Systémique de Qualité de vie pour Enfants” (ISQV-E©). Methods: This was a cross-sectional validation study. 288 children have completed the ISQV-E. Other tools were used: The “Autoquestionnaire de Qualité de Vie Enfants Imagé” (AUQUEI), the State-Trait Anxiety Inventory for Children (STAIC), the Children’s Depression Inventory (CDI) and socio-demographic data. Results: The internal consistency of the four scores of the ISQV-E (state, goal, rank and gap) is satisfactory. All scores have their own specificity. The data show the convergent validity, sensitivity and applicability of the ISQV-E. On the other hand, no satisfactory factorial structure was found although a multidimensional theoretical perspective was applied. Conclusions: The feasibility of the ISQV-E seems clearly demonstrated and the value of this new tool seems evident in contexts of physical, psychological or social problems. The validation study was promising but certain points such as test-retest reliability remain to be studied and the others, such as the absence of a satisfactory factorial structure, need to be examined again.

La nécessité d’évoluer vers des zones d’activité économique plus durables sous-tend cette recherche exploratoire autour du concept d’éco-zoning. Des investigations menées dans la littérature spécialisée, un recueil d’expériences et des entretiens avec des parties prenantes permettent de proposer une définition de référence qui s’articule sur le principe de la mise en oeuvre coordonnée de trois approches : l’aménagement et l’urbanisme, le management environnemental et l’écologie industrielle. Une proposition de grille d’évaluation des réalisations est formulée autour de critères d’encadrement et de performances. [less ▲]

Besides the concentric classical ratios, the eccentric isokinetic assessment of the muscle shoulder allows us to build some specific ratios. The mixed ratio combines the eccentric maximal contraction of the external rotators (ER) and the concentric maximal strength of the internal rotators (IR). The mixed ratio is frequently decreased among overhead athletes. This imbalance could rise to shoulder tendinopathy, but seemed to be linked with field performance. The functional ratio corresponds to the balance between the ER in concentric mode and the IR in eccentric contraction. The unstable shoulder shows a trend to lower functional ratios, highlighting the weakness of the eccentric IR in that pathology. [less ▲]

In this paper we discuss the criteria for recognition of foreign GAAPs applied by issuers of European Regulated Capital Markets. We also discuss the conditions to recognise inspections of audit firms auditing issuers on a EU Regulated Market carried out by foreign oversight authorities. We conclude that the concept of mutual recognition applied in the European Union differs from equivalence (or full reliance) applied in the US but in both cases it seems difficult to avoid the additional condition of convergence of standards.

Insulin resistance was already suspected in the thirties from clinical observations in diabetic patients, then better appreciated in the early sixties with the development of insulin radioimmunoassay, and finally confirmed in the last 20 years by using various sophisticated methods able to quantify insulin action. First demonstrated in obese and/or type 2 diabetic patients, the diminution of insulin sensitivity may in fact concern a much larger population. The concept of insulin sensitivity gained a considerable importance when Reaven, in 1988, emphasized the role of insulin resistance in different human diseases. The metabolic syndrome or syndrome X is characterized by the association of various cardiovascular risk factors (among which impaired glucose tolerance, arterial hypertension and dyslipidaemias), all closely linked to insulin resistance which is indeed the core of the syndrome. Even if insulin action signalling appears to be rather complex and the mechanisms leading to insulin resistance still largely unknown, it is essential to develop pharmacological or non pharmacological strategies to improve insulin sensitivity for treating insulin-resistant individuals. Such an approach should allow not only to provide a better blood glucose control in patients with type 2 diabetes, but also to improve the cardiovascular prognosis of numerous patients, with or without diabetes mellitus, who have the metabolic syndrome.

L’institution prend une place essentielle dans la pratique des sciences sociales, juridiques, économiques, etc., et ce, tant en termes de théorisation que d’approches empiriques. Aujourd’hui, cependant, à la lecture du concept de « gouvernance » ambiant, voire à la mode , il est intéressant de questionner notre manière de penser les institutions, que ce soit sur les pratiques qui les caractérisent, sur les rapports de forces internes ou ceux qu’elles entretiennent avec l’extérieur. Pourquoi tenter d’interroger les institutions au regard de la gouvernance ? Deux raisons sont principalement avancées. La première prend la forme d’une hypothèse posant l’existence d’un changement dans nos institutions et dont il reste à en identifier le caractère. Partant, quels rôles doit-on réserver aux acteurs et à la société civile ? Que peut-on dire de la prise en considération des institutions dans l’action publique ? La seconde raison se décline quant à elle en question de recherche et interroge un possible éclairage, par la notion de « gouvernance », du changement des institutions. Notre propos se scindera en deux parties. La première portera sur les indicateurs du changement de nos institutions et du caractère polysémique de la « gouvernance », tandis que la seconde tentera de savoir en quoi la compréhension du concept de « gouvernance » peut aider à l’étude de l’évolution des institutions.
