Iron balance and iron supplementation for the female athlete: A practical approach     

Charles R Pedlar  Carlo Brugnara  Georgie Bruinvels  Richard Burden 《European Journal of Sport Science》2018,18(2):295-305

Maintaining a positive iron balance is essential for female athletes to avoid the effects of iron deficiency and anaemia and to maintain or improve performance. A major function of iron is in the production of the oxygen and carbon dioxide carrying molecule, haemoglobin, via erythropoiesis. Iron balance is under the control of a number of factors including the peptide hormone hepcidin, dietary iron intake and absorption, environmental stressors (e.g. altitude), exercise, menstrual blood loss and genetics. Menstruating females, particularly those with heavy menstrual bleeding are at an elevated risk of iron deficiency. Haemoglobin concentration [Hb] and serum ferritin (sFer) are traditionally used to identify iron deficiency, however, in isolation these may have limited value in athletes due to: (1) the effects of fluctuations in plasma volume in response to training or the environment on [Hb], (2) the influence of inflammation on sFer and (3) the absence of sport, gender and individually specific normative data. A more detailed and longitudinal examination of haematology, menstrual cycle pattern, biochemistry, exercise physiology, environmental factors and training load can offer a superior characterisation of iron status and help to direct appropriate interventions that will avoid iron deficiency or iron overload. Supplementation is often required in iron deficiency; however, nutritional strategies to increase iron intake, rest and descent from altitude can also be effective and will help to prevent future iron deficient episodes. In severe cases or where there is a time-critical need, such as major championships, iron injections may be appropriate.  相似文献   

Who are the researchers that are collaborating with industry? An analysis of the wine sectors in Chile, South Africa and Italy     

Elisa Giuliani  Andrea Morrison  Carlo Pietrobelli  Roberta Rabellotti 《Research Policy》2010,39(6):748-761

Research on University-industry (U-I) linkages and their determinants has increased significantly in the past few years. However, there is still controversy on the key factors explaining the formation of U-I linkages, and especially related to individual researcher characteristics. This paper provides new empirical evidence and, in particular, looks at the importance of researchers’ individual characteristics and their institutional environments in explaining the propensity to engage in different types of U-I linkages. Based on an original dataset, we present new evidence on three wine producing areas - Piedmont, a region of Italy, Chile and South Africa - that have successfully responded to recent structural changes in the industry worldwide. Empirical findings reveal that researchers’ individual characteristics, such as centrality in the academic system, age and sex, matter more than publishing records or formal degrees. Institutional specificities at country level also play a role in shaping the propensity of researchers to engage with industry.  相似文献   

Les repre´sentations des futurs enseignants que´becois du primaire au regard de la formation initiale et des responsabilite´s des formateurs     

François Larose  Yves Lenoir  Vincent Grenon  Carlo Spallanzani 《欧洲师范教育杂志》2000,23(3):275-288

Dans cet article, nous faisons état des résultats d'une recherche menée auprès des divers intervenants du processus de formation initiale à l'enseignement préscolaire et primaire à l'Université de Sherbrooke. L'objectif de la recherche était de dégager les représentations sociales des diverses catégories d'intervenants au regard des concepts de compétence, de pédagogie et de didactique, ainsi que sur la place et les fonctions attribuées par les étudiants aux différents types de formateurs. Les résultats suggèrent que les étudiants ont des positions beaucoup plus rapprochées de celles des enseignants du primaire que de celles des formateurs universitaires. Ils montrent également plusieurs distinctions quant à l'attribution des compétences de formation aux divers types d'intervenants et quant aux lieux privilégiés de formation. Ces constats soulignent l'importance d'établir un dialogue plus étroit entre les divers partenaires de la formation initiale des futurs enseignants. In this paper, we present various results of a piece of research undertaken with different partners involved in the teacher education programme offered by the University of Sherbrooke (Canada). The main purpose of the research was to identify the place and role that should be taken by various categories of trainer. Our results suggest that students align their behaviour far more closely to that of serving teachers than they do to those of academics. Results also reveal many distinctions between students' categories about what are the specific competencies of the trainers as well as what is the best training context. These results confirm the importance that should be given to improving dialogue between the various partners in programmes of teacher education. En este artículo tratamos de los resultados de una investigación realizada con los varios actores del proceso de formación inicial docente al preescolar y al primario en la Universidad de Sherbrooke. El objectivo central de esta investigación era de indicar las representaciones sociales de dichas categorías de actores a propósito de los conceptos de competencia, de pedagogía y de didáctica, asíque el lugar y la función atribuida, de parte de los estudiantes, a las varias categorias de formadores. Segun los resultados de la investigación, las representaciones de los estudiantes quedan mucho mas cercanas de aquellas compartidas por los docentes del medio (preescolar y primario) que de las representaciones de los docentes universitarios. Se notan también muchas diferencias en terminos de reconocimiento de unas competencias a la formación y de lugares de formación mas importantes atribuidas a las varias categorias de formadores. Estos logros van en el sentido de mejorar el diálogo entre los varios partenarios de la formación de los docentes. In diesem Artikel stellen wir die Ergebnisse einer wissenschaftlichen Forschungsarbeit gegenüber verschiedener Intervenienten im Entwicklungsprozess der Grundausbildung in der Kindergartenausbildung sowie in der Grundschulausbildung auf der Universität von Sherbrooke vor. Vorhaben dieser Forschung war es die sozialen Vorstellungen der verschiedenen Kategorien von Interventienten gegenüber der Vorstellung von Kompetenz, Pädagogik und Didaktik, sowie die Stellung und Funktion verschiedener Ausbildungstypen hervorzuheben. Die Ergebnisse lassen darauf schliessen dass der Standpunkt der Studenten näher an den der Grundschullehrer herankommt als an den der Universitätsausbilder. Sie zeigen auch grundlegende Unterschiede in der Zuteilung der Kompetenzen der Ausbildung in den verschiedenen Interventionstypen sowie in den bevorteiligten Ausbildungsorten. Diese Feststellung unterstreicht die Wichtigkeit eines engeren Dialogs zwischen den verschiedenen Partnern der Grundausbildung des zukünftigen Lehrpersonals.  相似文献   

Reliability,sensitivity and validity of the assistant referee intermittent endurance test (ARIET) – a modified Yo-Yo IE2 test for elite soccer assistant referees

Abstract

We examined the reliability and validity of the assistant referee intermittent endurance test (ARIET), a modified Yo-Yo IE2 test including shuttles of sideways running. The ARIET was carried out on 198 Italian (Serie A-B, Lega-Pro and National Level) and 47 Danish elite soccer assistant referees. Reproducibility was tested for 41 assistant referees on four occasions each separated by one week. The ARIET intraclass correlation coefficients and typical error of measurement ranged from 0.96 to 0.99 and 3.1 to 5.7%, respectively. ARIET performance for Serie A and B was 23 and 25% greater than in Lega-Pro (P < 0.001). The lowest cut-off value derived from receiving operator characteristic discriminating Serie A-B from Lega-Pro was 1300 m. The ARIET performance was significantly correlated with [Vdot]O_2max (r = 0.78, P < 0.001), %HR_max after 4 min of ARIET (r = ? 0.81, P < 0.001) and Yo-Yo IR1 performance (r = 0.95, P < 0.001), but not sprint performance (r = ?0.15; P = 0.58). The results showed that ARIET is a reproducible and valid test that is able to discriminate between assistant referees of different competitive levels. The lack of correlation with sprinting ability and close correlations with aerobic power, intermittent shuttle running and sub-maximal ARIET heart rate loading provide evidence that ARIET is arelevant test for assessment of intermittent endurance capacity of soccer assistant referees.  相似文献   

Structural engineering and geology applied to the static problems of the Etruscan “Tomba dell’Orco” (Tarquinia,Central Italy)     

Salvatore D’Agostino  Gianni Lombardi  Gianpiero Russo  Carlo Viggiani 《Journal of Cultural Heritage》2010,11(1):107-112

The Etruscan Tomba dell’Orco was discovered in 1868. However, soon after discovery, part of its ceiling collapsed. An investigation was thus conducted with a view to assessing its safety conditions and permitting visitors’ access. Petrographic and physico-mechanical features of the local weak sandstones and mechanically more resistant calcareous sandstones “macco” were determined. Field mapping, drill-holes and geophysical prospecting helped reconstruct the stratigraphy of the volume where the tomb was excavated. The stability of the tomb basement is given by a thick macco layer. A few dm macco layer was identified above the ceiling. A model was then prepared with the Plaxis 2D V8.6 software. The safety coefficients calculated along two cross-sections of the tomb indicated that the margins for the tomb stability are reasonable.  相似文献   

Recent advances in swollen-state NMR spectroscopy for the study of drying oils     

Giacomo Cipriani  Antonella Salvini  Luigi Dei  Azzurra Macherelli  Francesco Saverio Cecchi  Carlo Giannelli 《Journal of Cultural Heritage》2009,10(3):388-395

The cross-linking processes of three drying oils (poppy, linseed, walnut), a class of organic compounds very important in the field of artworks, were studied by means of ¹H-NMR spectroscopy, following the change of the protons signals when oils are heated at 60 °C in the presence of air or nitrogen gas. This preliminary information is particularly important to identify the presence of drying oils within a solid painting film. We demonstrated that it was possible to study these films by swollen-state NMR, an innovative spectroscopy method that can directly analyze very small semisolid samples instead of solutions. The main advantages of this method are the short time of analysis, the possibility to analyze samples without any preliminary treatment, and the small quantity of the sample required. Therefore, swollen-state NMR technique was used to characterize three real painting films: in this way, we succeeded in recognizing in real paintings specimens the presence of drying oils employed as binders, avoiding any interferences due to other organic compounds acting as binding agents, like waxes or egg-yolk media.  相似文献

High-throughput size-based rare cell enrichment using microscale vortices   总被引：2，自引：0，他引：2  

Hur SC  Mach AJ  Di Carlo D 《Biomicrofluidics》2011,5(2):22206

Cell isolation in designated regions or from heterogeneous samples is often required for many microfluidic cell-based assays. However, current techniques have either limited throughput or are incapable of viable off-chip collection. We present an innovative approach, allowing high-throughput and label-free cell isolation and enrichment from heterogeneous solution using cell size as a biomarker. The approach utilizes the irreversible migration of particles into microscale vortices, developed in parallel expansion-contraction trapping reservoirs, as the cell isolation mechanism. We empirically determined the critical particle∕cell diameter D(crt) and the operational flow rate above which trapping of cells∕particles in microvortices is initiated. Using this approach we successfully separated larger cancer cells spiked in blood from the smaller blood cells with processing rates as high as 7.5×10(6) cells∕s. Viable long-term culture was established using cells collected off-chip, suggesting that the proposed technique would be useful for clinical and research applications in which in vitro culture is often desired. The presented technology improves on current technology by enriching cells based on size without clogging mechanical filters, employing only a simple single-layered microfluidic device and processing cell solutions at the ml∕min scale.  相似文献
