El acercamiento de la monarquía castellana a la Orden de los Predicadores durante el reinado de Juan II de Castilla (1406-1454)

Desde la llegada al trono de la dinastía Trastámara los diferentes monarcas castellanos llevaron a cabo una serie de actuaciones respecto a las órdenes religiosas. Durante los primeros años, éstas estuvieron dirigidas, en su mayoría, a la orden franciscana, a lo que habría que sumar la introducción en Castilla de la orden de la Cartuja y las primeras fundaciones jerónimas. Sin embargo, las reinas Beatriz de Portugal y Catalina de Lancaster, junto al infante Fernando de Antequera, fueron los protagonistas del cambio devocional que se produjo en Castilla y que alcanzó su cénit al alcanzar la mayoría de edad Juan II. Desde finales del siglo XIV vieron la luz una serie de fundaciones dominicas y se reformaron algunos conventos por parte de estos personajes; de manera progresiva, comenzaron a confiar en los frailes de esta orden diferentes cometidos espirituales, sociales y políticos.

Maximilian’s Journeys through Spain and Brazil: The Long Way to the Mexican Empire

In May of 1864, Maximilian of Austria reached the Mexican coast, being this journey his last, ending three years later with his execution. Much has been written about the reasons that prompted his acceptance of the crown of Mexico, a country so distant in every sense of his cultural environment. However, years ago Maximilian had traveled to Spain and Brazil (to Spain twice) and these experiences, although not determinant, greatly influenced the decision of the Archduke, who saw the chance to realize a dream he had conceived on his trip to Spain and that was consolidated during his stay in Brazil, as we can extract from his travel memoirs.

Levels of glucose and triglycerides in seminal plasma and spermatic motility in guinea pig fed with 10% more in digestible energy

The objective the study was to determine the levels of glucose and triglycerides in seminal plasma of 10 guinea pigs, which were fed for a period of 2 months with a diet containing 10% more ED. The level of glucose found in seminal plasma was 11.59 ± 0.5 mg/dL and triglyceride value was 55.95 ± 3.2 mg/dL, while the motility was 97% on average. We conclude that in guinea pigs the levels both glucose and triglycerides were increased by major level of ED in feed, but the spermatic motility was not.
