Análisis molecular de la valoración del intervalo de tiempo óptimo entre la administración de acetato de triptorelina y la punción folicular en los t…
2023
Los fármacos análogos de la GnRH y la hCG han demostrado ser igualmente eficaces en la activación de la cascada de intermediarios de la maduración final ovocitaria que ocurre tras el estímulo ovulatorio. Sin embargo, su mecanismo de acción y por tanto los perfiles hormonales hallados tras el estímulo de los dos fármacos son muy diferentes. El tiempo más adecuado para programar la recolección ovocitaria tras la administración de acetato de triptorelina podría no ser 36 horas como ampliamente se ha pautado en los tratamientos de FIV con hCG. Este intervalo de tiempo es sumamente importante para obtener la mayor proporción posible de ovocitos MII porque procesos como el inicio de la luteinizac…
lhc phenomenology and neutrino physics in gut inspired susy models
2014
En la primera parte de la tesis investigamos un modelo supersimetrico con un mecanismo seesaw para explicar las masas de los neutrinos. Implementamos el modelo en SPheno que nos permitió calcular observables de LHC (Large Hardron Collider) como por ejemplo los ``Edge observables''. Con la ayuda de estos observables pudimos reconstruir el espectro de masa de una teoría como SUSY y compararlo con los resultados de los experimentos. Como no hemos observado SUSY en ningún experimento calculamos para diferentes parámetros de SUSY el espectro usando errores esperados para nuestra análisis. Para poder decidir si un modelo resulta verdadero necesitamos un valor independiente que nos permita cuantif…
Study of Bs->PhiGamma decays at LHCb
2021
This thesis describes two different analyses performed at LHCb using the B0s→φγ and B0→K∗0γ decay channels. First, the measurement of the ratio of branching fractions B(B0→K∗0γ)/B(B0s→φγ) is presented, giving the most precise value for B(B0s→φγ) to date. Secondly, the CP-violating observables S and C, as well as the mixing-induced A∆ parameter are measured through a time-dependent analysis of the B0s→φγ decay channel, this being the first time the S and C observables are probed in the Bs system. These studies are performed using data collected in 2011 and 2012 by the LHCb experiment at CERN, corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions at a center-of-mass energy of…
Places of Belonging, Places of Detachment:
2022
This chapter contributes to the ongoing discussion about rural belonging by considering the role of historical consciousness (Rüsen, 2004) in the process of belonging in a place. The chapter suggests that young people’s temporal orientation in relation to local culture and history plays a significant role in their commitment to rural communities. The analysis draws on qualitative longitudinal data from Finnish girls, aged 16–19, from two sparsely populated regions (Central Finland and the Northern Finnish Sámi homeland). The chapter shows how multiple strands of commitment tie rural young people to their local surroundings, where the past is present in the landscape and everyday life in a m…

Access to Justice or Access to States Courtss Justice in Europe? The Directive 2008/52/EC on Civil and Commercial Mediation
2013
Modern societies are very much linked to the idea of litigation. A hidden rule seems to exist in the sense that the more advanced a society is the highest level of litigation it suffers. This increase in the level of litigation amounts to a sort of “litigation explosion” that has traditionally been linked to State courts. This explosion is said to put the whole judiciary system under pressure in so far the volume of disputes brought before State courts increases, the proceedings become more and more lengthy and the costs incurred in such proceedings also augment. The goal to tackle this explosion underpins most of the reforms that modern national civil procedure laws have suffered in many c…
Data from: Morphology and genetics reveal an intriguing pattern of differentiation at a very small geographic scale in a bird species, the forest thr…
2014
Mobile organisms are expected to show population differentiation only over fairly large geographical distances. However, there is growing evidence of discrepancy between dispersal potential and realized gene flow. Here we report an intriguing pattern of differentiation at a very small spatial scale in the forest thrush (Turdus lherminieri), a bird species endemic to the Lesser Antilles. Analysis of 331 individuals from 17 sampling sites distributed over three islands revealed a clear morphological and genetic differentiation between these islands isolated by 40–50 km. More surprisingly, we found that the phenotypic divergence between the two geographic zones of the island of Guadeloupe was …
Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.
2000
The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…
OGT and OGA expression in postmenopausal skeletal muscle associates with hormone replacement therapy and muscle cross-sectional area
2013
Protein glycosylation via O-linked N-acetylglucosaminylation (O-GlcNAcylation) is an important post-translational regulatory mechanism mediated by O-GlcNAc transferase (OGT) and responsive to nutrients and stress. OGT attaches an O-GlcNAc moiety to proteins, while O-GlcNAcase (OGA) catalyzes O-GlcNAc removal. In skeletal muscle of experimental animals, prolonged increase in O-GlcNAcylation associates with age and muscle atrophy. Here we examined the effects of hormone replacement therapy (HRT) and power training (PT) on muscle OGT and OGA gene expression in postmenopausal women generally prone to age-related muscle weakness. In addition, the associations of OGT and OGA gene expressions with…
Pharmacological investigation into the effects of histamine and histamine analogues on guinea-pig and rat colon in vitro.
1986
The effects of histamine and specific histamine agonists has been examined on isolated longitudinal colon strips of guinea-pig and rat. Histamine and 2-pyridyl-ethylamine but not 4 methylhistamine produced a concentration-related contractile response in the guinea-pig colon. The H1-antagonist clemizole antagonized competitively the effect of histamine but the H2-antagonist ranitidine did not modify the dose-response curve to histamine in the guinea-pig colon. Atropine, hexamethonium, prazosin and propranolol failed to modify the contractile response to histamine. Tone induced with KCl in guinea-pig isolated colon was not modified by histamine agonists even in tissues pretreated with clemizo…
