Injury History and Perceived Knee Function as Risk Factors for Knee Injury in Youth Team-Sports Athletes
2022
Background: The identification of risk factors for sports injuries is essential before injury prevention strategies can be planned. Hypothesis: Previous acute knee injury and lower perceived knee function measured by Knee injury and Osteoarthritis Outcome Score (KOOS) will increase the risk of acute knee injury in youth team-sports athletes. Study Design: Prospective cohort study. Level of Evidence: Level 3. Methods: At baseline, youth (≤21 years old) male and female basketball and floorball athletes completed a questionnaire on previous acute knee injuries and perceived knee function (KOOS). A total of 211 male and 183 female athletes were followed for an acute knee injury up to 3 years. U…
Fish introductions and light modulate food web fluxes in tropical streams : a whole-ecosystem experimental approach
2016
Decades of ecological study have demonstrated the importance of top-down and bottom-up controls on food webs, yet few studies within this context have quantified the magnitude of energy and material fluxes at the whole-ecosystem scale. We examined top-down and bottom-up effects on food web fluxes using a field experiment that manipulated the presence of a consumer, the Trinidadian guppy Poecilia reticulata, and the production of basal resources by thinning the riparian forest canopy to increase incident light. To gauge the effects of these reach-scale manipulations on food web fluxes, we used a nitrogen (15N) stable isotope tracer to compare basal resource treatments (thinned canopy vs. con…
First measurements of field metabolic rate in wild juvenile fishes show strong thermal sensitivity but variations between sympatric ecotypes
2021
The relationship between physiology and temperature has a large influence on population-level responses to climate change. In natural settings, direct thermal effects on metabolism may be exaggerated or offset by behavioural responses influencing individual energy balance. Drawing on a newly developed proxy, we provide the first estimates of the thermal performance curve of field metabolism in a wild fish. We investigate the thermal sensitivity of field metabolic rate in two sympatric, genetically distinct ecotypes of Atlantic cod from the Skagerrak coast of southern Norway. The combined ecotype median of field metabolic rate increased with increasing temperature until around 16°C, coincide…
Coronal properties of active G-type stars in different evolutionary phases
2005
We report on the analysis of XMM-Newton observations of three G-type stars in very different evolutionary phases: the "weak-line" T Tauri star HD 283572, the Zero Age Main Sequence star EK Dra and the Hertzsprung-gap giant star 31 Corn. The X-ray luminosities of the three stars are all in the range 10(30) - 10(31) erg/s. We compare the Emission Measure Distributions of these bright sources, derived from high-resolution X-ray spectra, as well as the pattern of elemental abundances vs. First Ionization Potential (FIP). The results of our analysis suggest that the coronae of these stars are very similar in terms of dominant coronal magnetic structures, in spite of differences in their evolutio…
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

Topic tacrolimus, alternative treatment for oral erosive lichen planus resistant to steroids : a case report
2006
The lichen planus is a mucocutaneous disease with unknown etiology and auto-immune pathogenia. There have been three variants of lichen planus: the reticular, the plaque-like and the atrophic-erosive lesions. It?s a chronic disease with acute relapses that generally affects more frecuently to women from the fourties. The diagnostic is based on the clinic identification of the lesions joined with the histopathologic study (basal cells hidropic degeneration, linfoplasmocitic infiltration and absence of displasy signs). The great number of therapeutic options are explained for its high prevalency (0.5-2%), its recurrence and its risk for malignant transformation. We present a case of oral eros…
Uso de las coronas telescópicas en el tratamiento de un paciente adulto con fisura labiopalatina: Puesta al día de la etiología y el tratamiento
2006
La fisura labiopalatina es una de las malformaciones congénitas craneofaciales más importantes a tener en cuenta por el odontólogo general debido a su alta incidencia y a su elevada repercusión en la cavidad oral. Sus causas se deben a factores genéticos y predominantemente a factores ambientales, haciendo su aparición ya en el período embrionario. El sexo masculino se encuentra más afectado, en una relación de 7:3. La asociación más frecuente es el labio leporino unilateral total con fisura palatina, que es el caso que nos atañe. Presentamos el caso de un varón de 20 años que acude a nuestra consulta demandando una solución estética a su situación dental. El tratamiento efectuado al pacien…
The Essential Oil of
2019
Many chemicals used nowadays for the preservation of cultural heritage pose a risk to both human health and the environment. Thus, it is desirable to find new and eco-friendly biocides that can replace the synthetic ones. In this regard, plant essential oils represent effective alternatives to synthetic substances for the preservation of historical monuments. Thymbra capitata (syn. Thymus capitatus) is a medicinal and aromatic plant growing in the Mediterranean area and endowed with important pharmacological properties related to its essential oil. Among them, the antimicrobial ones make the T. capitata essential oil an ideal candidate for industrial applications; for instance, as biocide f…
