Objective: Measurements of the variability in heart rate are increasingly used as markers of cardiac autonomic activity. We sought to establish the development this variability in healthy young infants while sleeping. Patients: We carried out polygraphic studies with electrocardiographic recording in 587 healthy infants aged from 5 to 26 weeks. Methods: We determined several variables over a period of 400 minutes sleeping: mean RR interval, 5 time-domain (SDNN, SDNNi, SDANNi, RMSSD, and pNN50) and 5 frequency-domain indexes (spectral power over 3 regions of interest, total power and low-to-high frequency ratio). Frequency-domain indexes were also assessed separately for the periods of quiet sleep and those of rapid eye movement sleep. Results: Our data showed a significant correlation between the indexes of heart rate variability and the mean RR interval, the breathing rate, and the corrected age of the infants. We also demonstrated the importance of the maturation of the sleeping patterns. Conclusion: These data in a large cohort of healthy infants confirm a progressive maturation of the autonomic nervous system during sleep, and may be used to examine the influence of physiological and pathophysiological factors on autonomic control during polygraphic studies.

BACKGROUND: Availability of normative reference values for cardiac chamber dimensions, volumes, mass, and function is a prerequisite for the accurate application of echocardiography for both clinical and research purposes. However, due to the lack of consistency in current echocardiographic 'reference values', their use for clinical decision-making remains questionable. AIMS: The aim of the 'Normal Reference Ranges for Echocardiography Study (NORRE Study)' is to obtain a set of 'normal values' for cardiac chamber geometry and function in a large cohort of healthy Caucasian individuals aged over a wide range of ages (25-75 years) using both conventional and advanced echocardiographic techniques. METHODS: The NORRE Study is a large prospective, observational multicentre study in which transthoracic echocardiographic studies will be acquired in 22 laboratories accredited by the European Association of Cardiovascular Imaging and in one laboratory in the USA accredited by ICAEL. The final sample size has been estimated in 1100 normal subjects in whom M-mode, 2D, and 3D imaging, colour Doppler, pulsed-wave Doppler, pulsed-wave tissue Doppler, and colour tissue Doppler imaging data will be obtained. All studies will be sent to a central echocardiographic core laboratory for quantitative analysis. Multiple studies will be performed for reproducibility analysis. CONCLUSION: After completion of the NORRE Study, uniform reference limits according to age, gender, and anthropometric parameters will be available to standardize the quantitative interpretation of echocardiography.

In nephrology, chronic kidney disease is defined by both proteinuria and measurement of glomerular filtration rate (GFR). This article focuses on GFR and different ways to define its normal reference values. In this context, we compare two perspectives: first the reference values defined by measuring GFR in normal individuals (the 'classical way') and secondly a fixed cut-off value at 60 mL/min/1.73 m(2) according to the associated mortality risk (the 'prognostic way'). Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m(2) in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m(2) could be considered normal. Following the 'prognostic way', the fixed cut-off of 60 mL/min/1.73 m(2) has been retained in the K-DIGO guidelines. However, we challenge this concept and the fact that the variable 'age' is poorly taken into account in these data. There is an obvious discrepancy between the reference values defined either by the 'classical way' or by the 'prognostic way' which we think could be largely reduced, if age was better taken into consideration in these definitions.

Rhophilin 2 is a Rho GTPase binding protein initially isolated by differential screening of a chronically thyrotropin (TSH)-stimulated dog thyroid cDNA library. In thyroid cell culture, expression of rhophilin 2 mRNA and protein is enhanced following TSH stimulation of the cyclic AMP (cAMP) transduction cascade. Yeast two-hybrid screening and coimmunoprecipitation have revealed that the GTP-bound form of RhoB and components of the cytoskeleton are protein partners of rhophilin 2. These results led us to suggest that rhophilin 2 could play an important role downstream of RhoB in the control of endocytosis during the thyroid secretory process which follows stimulation of the TSH/cAMP pathway. To validate this hypothesis, we generated rhophilin 2-deficient mice and analyzed their thyroid structure and function. Mice lacking rhophilin 2 develop normally, have normal life spans, and are fertile. They have no visible goiter and no obvious clinical signs of hyper- or hypothyroidism. The morphology of thyroid cells and follicles in these mice were normal, as were the different biological tests performed to investigate thyroid function. Our results indicate that rhophilin 2 does not play an essential role in thyroid physiology [less ▲]

Ce travail de recherche s'est attaché à retracer la généalogie de la norme ISO 14001. Celle-ci semble avoir émergé du croisement de trois champs d'action, à un moment bien particulier de leur évolution: le champ des politiques environnementales publiques, le champ de la normalisation technique et le champ des sciences de gestion. Cette mise en perspective spocio-historique permet de dénaturaliser un dispositif alors même que sa rapide diffusion le rend de plus en plus indiscutable, et de comprendre comment la norme ISO 14001 organise les relations entre ces trois champs d'action distincts.

This paper revisits the performance of funds of hedge funds after the crisis using normalized risk-adjusted performance measures based on multi-factor models. First, we develop performance measures able to capture the variety of systematic risk sources. Second, we deal with the impact of smoothing on the risk return properties of FoHF using an adjustment technic for illiquidity. Third, we implement unbiased estimators to correct for the econometric bias induced by errors-in-variables (EIV) in asset pricing models. With these different adjustments, we analyze the persistence and stability of performance measures before and after the crisis for a data base of funds of hedge funds. Our results clearly show that the normalized risk-adjusted performance measures corrected for smoothing effect and EIV outperform the alternatives measures before and after the crisis. [less ▲]

Partendo dal presupposto che la costruzione della soggettività individuale sia un processo composito e dinamico, questo intervento mira a metterne in evidenza i sostrati materiali, cioè quei fattori che agiscono direttamente sulla corporeità. In particolare, viene considerata la materialità delle pratiche alimentari e culinarie come luogo della definizione stratificata del sé. Tali pratiche dialogano con una pluralità di discorsi che sfumano i confini dei corpi individuali e li rendono permeabili agli effetti delle rappresentazioni collettive e delle appartenenze che queste determinano. L’intervento focalizzerà sulla storia di Bâhirah, una giovane donna di origine marocchina residente nella provincia di Milano. La sue pratiche del quotidiano, indagate con il metodo dell’osservazione partecipante e grazie ad interviste semi-strutturate, forniscono un esempio delle dinamiche enunciate sopra. L’importanza del cibo nella storia di questa donna è determinata da diversi fattori, tra i quali la malattia di una delle sue figlie, affetta da diabete mellito 1. Le disfunzioni corporee che caratterizzano questa patologia, determinano la necessità, da un lato, di un controllo minuzioso degli alimenti ingeriti (dunque incorporati) e degli elementi biologici che li compongono; dall’altro, una excorporazione di alcune funzioni fisiologiche legate all’alimentazione, delegate a strumenti esterni al corpo. Tali azioni sono finalizzate a conformare quest’ultimo ad una “normalità” definita da canoni biomedici, i quali permettono l’inclusione nella collettività “sana”. Il contesto più ampio in cui queste dinamiche si inseriscono, è costituito da una pluralità di discorsi, tra i quali in particolare quelli che riguardano il rapporto tra alimentazione e migrazione. Se da un lato si assiste ad un’ipermobilità delle gastronomie (o dei loro elementi), alla loro delocalizzazione e rilocalizzazione in culture alimentari altre, dall’altro la standardizzazione delle abitudini alimentari proprie alla diversità culturale sembra essere prerogativa essenziale della cosiddetta “integrazione” dei migranti. Tali dinamiche si ripercuotono sulla materialità delle (micro)pratiche quotidiane attorno al corpo che questo intervento si propone di analizzare. Le riflessioni saranno accompagnate da alcuni supporti visivi. [less ▲]

This article concerns the creation of norms and the validation in French of the Body Image Assessment – Revised (BIA-R; Beebe, Holmbeck, & Grzeskiewicz, 1999). The sample comprised 100 normal female subjects. They completed questionnaires assessing body experience, eating pathology, psychological functioning, general perception and the BIA-R (Beebe et al., 1999). This test consists of nine silhouettes from which the subject has to choose the somatotype corresponding to her actual shape (cognitive response), the way she feels (affective response) and the way she would like to look (optative response). The results show a good concurrent validity for the cognitive and affective indices and the affective/ cognitive vs. optative divergences. On the other hand, we were not able to demonstrate such validity for the optative index and the affective vs. cognitive divergence index [less ▲]
