Identificación de genes y polimorfismos asociados a fenotipos óseos
2017
El deterioro óseo sucede principalmente como consecuencia del envejecimiento en ambos sexos y particularmente con la depleción estrogénica que ocurre durante la menopausia en la mujer. Este deterioro en la calidad ósea puede desembocar finalmente en el desarrollo de patologías óseas como la osteoporosis, y en última instancia en el fenotipo clínico de peor pronóstico, la fractura ósea por fragilidad. Ambos fenotipos, la osteoporosis y la fractura por fragilidad, se consideran patologías complejas o multifactoriales; esto es, influenciadas por múltiples factores entre los que se encuentran factores genéticos, epigenéticos o ambientales. En la caracterización de los factores genéticos que int…
Método de cálculo de la potencia de la lente intraocular pseudofáquica en pacientes intervenidos previamente de cirugía refractiva corneal láser
2018
Antecedentes: El valor de la potencia de la lente intraocular (PLIO) que sustituirá al cristalino en una cirugía de cataratas o lensectomía refractiva, es una función de la longitud axial (LA), la posición efectiva de la lente (PEL) y la potencia corneal (PC). Estas variables se introducen en una fórmula que proporciona el valor preciso de la PLIO para alcanzar el resultado refractivo programado. En ojos sin cirugías corneales previas, el resultado refractivo tras el implante es el esperado, con pequeños errores no significativos clínicamente. Sin embargo, cuando se calcula la PLIO en pacientes intervenidos previamente de cirugía refractiva corneal láser (CRCL), el resultado no es tan preci…
Normalized Solutions to the Fractional Schrödinger Equation with Potential
2023
AbstractThis paper is concerned with the existence of normalized solutions to a class of Schrödinger equations driven by a fractional operator with a parametric potential term. We obtain minimization of energy functional associated with that equations assuming basic conditions for the potential. Our work offers a partial extension of previous results to the non-local case.
New high-pressure phase and equation of state of Ce2Zr2O8
2012
In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase of Ce2Zr2O8 transforms to a rhombohedral structure beyond 5 GPa with a feeble distortion in the lattice. Pressure evolution of unit-cell volume showed a change in compressibility above 5 GPa. The unit-cell parameters of the high-pressure rhombohedral phase at 12.1 GPa are ah = 14.6791(3) {\AA}, ch = 17.9421(5) {\AA}, V = 3348.1(1) {\AA}3. The structure relation between the parent cubic (P2_13) and rhombohedral (P3_2) phases were obtained by group-subgroup relations. All t…
Physico-chemical characterisation of a non-conventional food protein source from earthworms and sensory impact in arepas
2009
International audience; This study aimed to characterise a non-conventional protein source: a powder made from earthworms, and to evaluate its potential use as human food. The way it was prepared led to low solubility and wide particle size distribution. Sensory analysis was used to assess the acceptability and the organoleptic properties of maize-based pan-cakes fortified with this novel protein powder. Satisfying products were obtained with a substitution level of 5.5% (w/w) earthworm powder in pan-cakes. GC-MS allowed the identification of more than seventy volatile compounds that may be responsible for the off-odour of the powder. The most abundant chemical groups found in the volatile …
Preoperativ oppvarming av pasienter med hoftebrudd : Kan preoperativ oppvarming med varmluftsteppe redusere intraoperativt temperaturfall hos pasient…
2018
Masteroppgave spesialsykepleie ME519 – Universitetet i Agder 2018 Background: Hip fractures are a common cause of hospitalization and are linked with high morbidity and mortality rates. It is therefore important to optimize every aspect of their treatment to minimize complications. The Nurse Anesthetist plays an important role in preventing complications related to both surgery and anesthesia. Purpose: The aim of this project is to evaluate the quality of the current procedure for preoperative prevention of hypothermia in our hospital. We wanted to investigate if this procedure for preventing hypothermia is as effective as preoperative warming with a forcedair system in hip fracture patient…
L’appréhension de l’inceste non-consenti par le droit pénal. Réflexions comparatistes sur l’usage du mot inceste en droit pénal
2023
Les infractions sexuelles visant des personnes vulnérables soulèvent deux types de problème. D’abord, celle de l’appréhension du consentement à une relation sexuelle pour les personnes au-dessus de l’âge de la majorité sexuelle. Ensuite, celle de l’effet psychologique que de telles infractions peuvent avoir sur les victimes et qui justifient une modulation du régime de prescription. Au sein de ces débats, certaines spécificités ressortent s’agissant des relations intra-familiales non consenties. L’appréhension du consentement sexuel peut en effet être rendue compliquée par de telles relations. De même, l’effet psychologique de l’inceste pourrait en théorie justifier certaines normes dérogat…
Multifacial Recognition in Binary and Ternary Cocrystals from 5-Halouracil and Aminoazine Derivatives
2018
A systematic analysis using single crystal X-ray diffraction was performed to explore the role exerted by potential intercomponent proton-transfer reactions in the supramolecular structures of A–B cocrystals formed by 5-haloderivatives of uracil (A), coupled with 2-aminoadenine simulants (aminoazines, B). Twelve new heterodimers were synthesized in different stoichiometries and cocrystallized by solvent cogrinding followed by solution crystallization. In the binary cocrystals, uracil or 1-methyluracil with halide modification at the 5 position (F, Cl, Br, I) was coupled with amino-aromatic N-heterocycles (melamine, 2,4,6-triaminopyrimidine, 2,6-diaminopyridine) as a multivalent site for pyr…
Les ecclésiastiques devant le tribunal de district de Dijon sous la période révolutionnaire : l'application du gallicanisme
2008
International audience; Avec la constitution civile du clergé du 12 juillet 1790, sanctionnée le 24 août, la Constituante entend imposer son idéal politique aux ecclésiastiques. Ceux-ci, comme sous l'Ancien Régime, sont encadrés et surveillés par les autorités séculières, en particulier par les tribunaux. Aussi, l'étude des archives du tribunal de district de Dijon, statuant au civil et au pénal, apporte-t-elle de précieux compléments aux études nationales et locales, le prisme des litiges ordinaires révélant les conséquences concrètes des nouvelles règles dans la vie quotidienne des clercs. Les registres du tribunal de district de Dijon, pour la période révolutionnaire, comportent plus de …
