Purpose: To examine how match performance parameters in trained footballers relate to skeletal muscle parameters, sprint ability and intermittent exercise performance. Methods: 19 male elite football players completed an experimental game with physical performance determined by video analysis and exercise capacity assessed by intermittent Yo-Yo IR1 and IR2 tests, and a repeated sprint test (RST). Muscle tissue was obtained for analysis of metabolic enzyme maximal activity and key muscle protein expression. Results: Total game distance, distance deficit from first to second half and high-intensity running in the final 15 min of the game were all correlated to the players’ Yo-Yo IR1 performance (r = 0.55–0.87) and beta-hydroxyacyl-CoA-dehydrogenase (HAD) maximal activity (r = 0.55–0.65). Furthermore, platelet/endothelial cell adhesion molecule-1 (PECAM1) protein expression was weakly (r = 0.46) correlated to total game distance. Peak 5-min game distance faster than 21 km h−1 was related to the Na+–K+ ATPase subunit (α1, α2, β1 and FXYD1) protein levels (r = 0.54–0.70), while Yo-Yo IR2 performance explained 40 % of the variance in high-intensity game distance. Total and 1-min peak sprint distance correlated to myosin heavy chain II/I ratio (MHCII/I ratio) and sarcoendoplasmic reticulum Ca2+ ATPase isoform-1 (SERCA1) protein (r = 0.56–0.86), while phosphofructokinase (PFK) maximal activity also correlated to total sprint distance (r = 0.46). Conclusion: The findings emphasize the complexity of parameters predicting physical football performance with Yo-Yo IR1 and HAD as the best predictors of total distance, while high expression of Na+–K+ ATPase proteins and the Yo-Yo IR2 test are better predictors of high-intensity performance. Finally, sprint performance relates to skeletal muscle fiber-type composition. © 2015, Springer-Verlag Berlin Heidelberg.

Leptospira interrogans is a bacterium that can infect most mammal species. Brown rats are considered to be one of the most important reservoirs of Leptospira because they frequently are infected and live in close proximity to humans. Past studies of prevalence of Leptospira in brown rats indicate that temperature - both high and low - may negatively affect the prevalence rate in rats, so that Leptospira is rare or even absent at temperatures below 7-8 °C. Here we investigated the prevalence of infection in brown rats on the Faroese Islands (mean temperature of 6.5 °C) and did not find any infected animals in a sample of 95 animals. We propose that prevalence rates of Leptospira are very low in rural brown rats in the cooler Scandinavian regions, even though urban/sewer rats might be highly infected in the same regions. © 2015 Society for Scandinavian Journal of Infectious Diseases.

BACKGROUND:: In mysterious ways, hope makes life meaningful even in chaotic and uncontrolled situations. When a woman is newly diagnosed with gynecologic cancer, hope is ineffable and needs exploring. Drawings help express ineffable phenomena. OBJECTIVE:: The aim of the study was to explore how women newly diagnosed with gynecologic cancer express the meaning of hope in drawings. METHOD:: Participants were 15 women who on the same day had received the diagnosis of gynecologic cancer. They were between 24 and 87 years (median, 52 years) with a variety of gynecologic cancer diagnoses. Data from 15 drawings and postdrawing interviews with the women were analyzed using visual and hermeneutic phenomenology. RESULTS:: Three themes emerged: hope as a spirit to move on, hope as energy through nature, and hope as a communion with families. CONCLUSION:: Hope as pictured in drawings often appears through metaphors and incorporates internal, external, and relational aspects. With other words, inner willpower, experiences in open nature, and closeness to loved ones contribute to hope when newly diagnosed with gynecologic cancer. IMPLICATION FOR PRACTICE:: The use of drawings in clinical situations might give cancer nurses new perceptions of hope and other phenomena. Patients might feel threat and despair when diagnosed with cancer; they need gentle truth about reality, and they long for being together with loved ones. Nurses are in a unique position to enable hope in this situation through listening and active engagement. Drawing might be a tool in understanding the hope. Drawings picture where words come short.

Models, according to common understanding, facilitate to make and share references. A reference is a deictic activity whose point of origin differs from its target. The activity of modeling rests on taking a reference's point of origin as a substitute for its target. In this paper I discuss two aspects of modeling, namely abstraction and direction-of-fit. I am going to show that representation, rather than abstraction, is key to modeling and that the direction-of-fit is not inherent to a model. © Springer-Verlag 2013.

Small-strain oscillatory measurements and size-exclusion chromatography coupled to multiangle laser light scattering were used to study the mechanical properties and the molecular weight distribution, respectively, of acid porcine skin gelatins (type A), lime bovine bone gelatins (type B), and cold water fish gelatins, while principal component analysis (PCA) and partial least squares regression were used to relate the mechanical properties with the molecular weight distribution. The present study suggests a linear relationship between the mechanical properties and the fractions of low molecular weight (LMW) molecules, α-chains, β-chains, and high molecular weight (HMW) molecules. The Bloom value for mammalian gelatin was positively correlated with the fractions of α-chains, β-chains, and HMW molecules and negatively correlated with the fraction of LMW molecules. The dynamic storage modulus for cold water fish gelatin was positively correlated with the fractions of β-chains and HMW molecules and negatively correlated with the fractions of LMW molecules and α-chains. © 2009 Springer Science+Business Media, LLC.
