Le patient souffrant d'insuffisance rénale terminale est exposé à une mortalité de 5 à 30 fois supérieure à celle de la population générale à âge identique. Au moins 50% de cette surmortalité sont dus à des complications cardiovasculaires. Des signes de coronaropathie et d'insuffisance cardiaque sont déjà présents chez 40% de patients au début des traitements par dialyse. Ce risque cardiovasculaire apparaît très tôt dans le processus de dégradation de la fonction rénale et aumente au fur et à mesure de la progression de l'insuffisance rénale. Un patient souffrant de maladie rénale a plus de probabilité de décéder d'un problème cardiovasculaire que d'évoluer vers l'insuffisance rénale terminale. Plusieurs études épidémiologiques menées aux Etats-Unis, que ce soit l'étude NHANES III (National Health And Nutrition Examination Survey) ou encore l'étude ARIC (Atherosclerosis Risk in Communities), démontrent toutes que ce risque cardiovasculaire s'élève particulièrement dès que la filtration glomérulaire s'abaisse en dessous de 60 ml/min/1,73 m². Ceci vient d'être confirmé sur un suivi de près de 3 ans chez plus d'un million de sujets, tant pour le risque de décès, d'accidents cardiovasculaires que d'hospitalisations. Par ailleurs, le devenir de patients ayant présenté un infarctus du myocarde est plus sombre en présence d'une insuffisance rénale. Chaque diminution de 10 ml/min de la filtration glomérulaire, à partir de 80 ml/min, augmente le risque de complication de 10% chez des sujets ayant souffert d'un infarctus. [less ▲]

This paper is a modeling of the rigid community or clan which the organizing core is a «hidden antagonism». The family beliefs cluster the members around a joint project related to appearing and to having it. But a subsystem develops and reintroduces a difference in this monolith. This subsystem is based on elements related to being and feeling, but also to ambiance, spirituality, aesthetics, suffering and pathology. This « hidden opposing » force dissimulated in the family « underground » remains unknown but works with an equal power to sustain the community unity. However, it uses radically different means than the dominating subsystem. Although each subsystem thinks it supports the system unity, it is more the conjunction of the two of them (in a hidden antagonism) that is the organizing principle of the clan. Cet article présente une modélisation du clan dont le principe organisateur est un « antagonisme caché ». Les croyances familiales unissent l'ensemble des membres autour d'un projet commun lié au paraître et à l'avoir. Mais un sous-système se construit, qui réintroduit une différence dans ce monolithe, à partir de valeurs proches de l'être et de l'éprouvé, des valeurs liées à l'ambiance, à la spiritualité, à l'esthétique, à la souf¬france et à la pathologie. Ce sous-système appelé «contestant caché », dissimulé dans le maquis familial, n'est reconnu par personne, et pourtant il agit avec autant de puissance que l'autre sous-système appelé « dominant», pour soutenir l'unité de la communauté, mais par des moyens radicalement opposés à ceux du sous-système «dominant». <br />Le processus organisateur du clan est donc animé par un antagonisme caché entre deux sous-systèmes dont chacun tente d'imposer ses propres moyens de produire l'unité, alors que le clan se nourrit de leur lutte sous-jacente.

N-Acyl-beta-sultams are time-dependent, irreversible active site-directed inhibitors of Streptomyces R61 DD-peptidase. The rate of inactivation is first order with respect to beta-sultam concentration, and the second-order rate constants show a dependence on pH similar to that for the hydrolysis of a substrate. Inactivation is due to the formation of a stable 1:1 enzyme-inhibitor complex as a result of the active site serine being sulfonylated by the beta-sultam as shown by ESI-MS analysis and by X-ray crystallography. A striking feature of the sulfonyl enzyme is that the inhibitor is not bound to the oxyanion hole but interacts extensively with the "roof" of the active site where the Arg 285 is located. [less ▲]

A retrospective epidemiological study (n = 7,875) of neurologically expressed disorders (NED) in ruminants before the onset of the bovine spongiform encephalopathy epidemic (years studied, 1980 to 1997) was carried out in Belgium. The archives of all veterinary laboratories and rabies and transmissible spongiform encephalopathy (TSE) epidemiosurveillance networks were consulted. For all species, a significantly higher number of NED with virological causes (rabies) was reported south of the Sambre-Meuse Valley. During the period 1992 to 1997, for which the data were complete, (i) the predicted annual incidence of NED varied significantly as a function of species and area (higher numbers in areas where rabies was present) but was always above 100 cases per million, and (ii) the mean incidence of suspected TSE cases and, among them, those investigated by histopathological examination varied significantly as a function of species and area. The positive predictive value of a presumptive clinical diagnosis of NED ranged from 0.13 (game) to 0.63 (sheep). Knowledge of the positive predictive value permits the definition of a reference point before certain actions (e.g., awareness and training campaigns) are undertaken. It also shows the usefulness of a systematic necropsy or complementary laboratory tests to establish an etiological diagnosis. TSE analysis of a small, targeted historical sampling (n = 48) permitted the confirmation of one case and uncovered another case of scrapie. The results of the present study help to develop and maintain the quality of the worldwide clinical epidemiological networks for TSE, especially in countries that in the past imported live animals, animal products, and feedstuffs from countries with TSE cases.

Energy metabolism of skeletal muscles in cattle is characterized by several specificities, mostly related to particularities of the digestive physiology. Energy metabolism of muscles relies on preferential utilization of some nutrients, such as volatile fatty acids and ketone bodies on the one hand, and glucose on the other hand, the contribution of non-esterified long chain fatty acids being limited. As for other species, nutrients utilization is influenced by the nature of muscle fibers, leading to preferential metabolic pathways. Energy metabolism can be either more oxidative, oxido-glycolytic, or glycolytic. Close relationships are found between energy metabolism, chemical composition of muscle - more particularly its fat level - and organoleptic quality of meat. [less ▲]

T70N human lysozyme is the only known naturally occurring destabilised lysozyme variant that has not been detected in amyloid deposits in human patients. Its study and a comparison of its properties with those of the amyloidogenic variants of lysozyme is therefore important for understanding the determinants of amyloid disease. We report here the X-ray crystal structure and the solution dynamics of T70N lysozyme, as monitored by hydrogen/deuterium exchange and NMR relaxation experiments. The X-ray crystal structure shows that a substantial structural rearrangement results from the amino acid substitution, involving residues 45–51 and 68–75 in particular, and gives rise to a concomitant separation of these two loops of up to 6.5 Å. A marked decrease in the magnitudes of the generalised order parameter (S2) values of the amide nitrogen atom, for residues 70–74, shows that the T70N substitution increases the flexibility of the peptide backbone around the site of mutation. Hydrogen/deuterium exchange protection factors measured by NMR spectroscopy were calculated for the T70N variant and the wild-type protein. The protection factors for many of backbone amide groups in the β-domain of the T70N variant are decreased relative to those in the wild-type protein, whereas those in the α-domain display wild-type-like values. In pulse-labelled hydrogen/deuterium exchange experiments monitored by mass spectrometry, transient but locally cooperative unfolding of the β-domain of the T70N variant and the wild-type protein was observed, but at higher temperatures than for the amyloidogenic variants I56T and D67H. These findings reveal that such partial unfolding is an intrinsic property of the human lysozyme structure, and suggest that the readiness with which it occurs is a critical feature determining whether or not amyloid deposition occurs in vivo.
