MODIFICATIONS OF SOME PARAMETERS OF THE RABBIT EJACULATE AFTER ABLATION OF THE VESICULAR GLAND

[EN] An evaluation is made of the influence which the vesiculectomy may have on the ejaculate in the rabbit. To do this we have studied three different factors in the semen, before and after the operation: quality control parameters (volume, vitality and concentration), presence or not of the mucous plug and levels of different ions (sodium, potassium, calcium and magnesium) in the rabbit's seminal ¡tasma. At the same time we performed periodical determinations o these ions in the blood plasma, in order to rule out the fact that the variations of the cation levels in the seminal plasma could be due to alterations of these levels in the bloodreduction in the seminal quality parameters analysed (46,4% for concentration, 29.5% for vitality and 45,6% for volume). On the other hand, as far as the concentration of the different ions in seminal plasma is concemed, a significant fall in the case of sodium (21.1 %) is observad and a parallel increase of the calcium, magnesium and potassium ions, although the difference is only significant in the first ofthe three (19%) .[FR] Cette étude évalue l'influence que peut avoir la vésiculectomie sur l'éjaculat du lapin. Pour cela nous avons étudié 3 paramétres de la semence avant et aprés l'opération : controle de la qualité (volume, vitalité et concentration), présence ou non de mucus, taux des différents íons (Sodium, Potassium, Calcium et Magnésium) dans le plasma séminal du lapin. Parallélement nous avons contrOlé périodiquement la concentration de ces ions dans le plasma sanguin afin de vérifier si la variation du taux de ces cations dans le liquide séminal n'est pas dO a leur variation dans le plasma sanguin. Nos résultats montrent qu'une vésiculectomie partielle conduit a la disparition du mucus dans l'éjaculat, ainsi qu'a un réduction significative des paramétres de qualité analysés (46,4 % pour la concentration, 29,5 % pour la vitalité et 45,6 % pour le volume). La concentration des différents ions dans le plasma séminal est peu affectée, bien que l'on observe une diminution significative du taux de Sodium (21, 1 %) et une augmentation paralléle du Calcium, du Magnésium et du Potassium, avec un différence significative (19%) seulement pour le premier des trois.Del Niño Jesús, A.; Muños López, I.; Josa, A.; Espinosa, E.; Gracia, M.; García Martínez, M.; Leuza, A.

Leveraged Buyouts: A Survey of the Literature

This paper provides an exhaustive literature review of the motives for public-to-private LBO transactions. First, the paper develops the theoretical framework for the potential sources of value creation from going private: a distinction is made between the reduction in agency costs, stakeholder wealth transfers, tax benefits, transaction costs savings, takeover defense strategies, and corporate undervaluation. The paper then reviews and summarizes whether and how these theories have been empirically verified in the four different strands of literature in LBO research. These strands of literature are categorized by phase in the LBO transaction: Intent (of a buyout), Impact (of the LBO on the various stakeholders), Process (of restructuring after the leveraged buyout) and Duration (of retaining the private status). Then, the paper shows that in the first half of the 2000s, a public-to-private LBO wave re-emerged in the US, UK and Continental Europe, whose value vastly exceeded that of the 1980s US LBO wave. Finally, the paper provides suggestions for further research
