La dinámica del viaje en el contexto del Ms. Esc. K-III-4 : Libro de Apolonio, Vida de Santa María Egipciaca, Libro de los tres reyes de Oriente

Resumen: Los personajes de los tres poemas castellanos del temprano siglo XIII que componen el manuscrito K-III-4 de la Biblioteca de San Lorenzo de El Escorial (Libro de Apolonio, Vida de Santa María Egipciaca, Libro de los tres reyes de Oriente) viajan lamentando aquello que han perdido a causa de la ira regia, el propio pecado o la amenaza de muerte inminente, pero también para superar esas pérdidas. Esos viajes representan la medida de una aventura medieval cuya dinámica expresa la concepción profunda de la trayectoria vital como prueba cristiana, según se analizará en el presente trabajo.

Diversidad de artrópodos asociada a dos sistemas de manejo de plantación de Marango (Moringa oleifera Lam.) en la Finca Santa Rosa, Managua

Debido a pocos estudios sobre los artrópodos asociados a Moringa oleifera Lam., se llevó a cabo una caracterización de la diversidad dinámica poblacional y el rol potencial a nivel de orden familia y especie en dos sistemas de manejo de plantación para producción de semillas. La evaluación se llevó a cabo por un periodo de 12 semanas. La colecta se realizó a través del uso de trampas Pitfall y trampas aéreas en lotes de plantación de Moringa oleifera manejadas como monocultivo convencional; y manejo con enfoque agroecológico. Los parámetros registrados en cada sistema de manejo fueron: abundancia riqueza y, diversidad a partir del índice de Shannon Wiener. Los resultados reportan 1775 especímenes colectados, registrándose menor abundancia en manejo convencional (800 individuos) en comparación con manejo agroecológico (975 individuos). La fluctuación poblacional fue diferente en cada sistema de manejo, dándose un mayor incremento entre Noviembre y Enero en manejo agroecológico. La composición de artrópodos estuvo compuesta por 10 ordenes 55 familias y 73 especies. Los órdenes más representativos fueron Hymenoptera, Diptera, Orthoptera y Coleópeta. Las familias más representativas fueron Formicidae, Muscidae, Acrididae, Chrisopidae, Pyralidae y Blattellidae; reportando mayor índice de diversidad (3.2) en manejo agroecológico. La riqueza de especies fue más alta en manejo agroecológico (69) en comparación con manejo convencional (52). En cuanto al rol potencial de las especies en manejo agroecológico fue identificado 49.2% de defoliadores, 42.02% son benéficos mientras en manejo convencional 51.9% don defoliadores y 40.3 son especies benéficas.

Depletion of the heaviest stable N isotope is associated with NH4 +/NH3 toxicity in NH4 +-fed plants

Background: In plants, nitrate (NO(3)(-)) nutrition gives rise to a natural N isotopic signature (delta(15)N), which correlates with the delta(15)N of the N source. However, little is known about the relationship between the delta(15)N of the N source and the (14)N/(15)N fractionation in plants under ammonium (NH(4)(+)) nutrition. When NH(4)(+) is the major N source, the two forms, NH(4)(+) and NH(3), are present in the nutrient solution. There is a 1.025 thermodynamic isotope effect between NH(3) (g) and NH(4)(+)(aq) which drives to a different delta(15)N. Nine plant species with different NH(4)(+)-sensitivities were cultured hydroponically with NO(3)(-) or NH(4)(+) as the sole N sources, and plant growth and delta(15)N were determined. Short-term NH(4)(+)/NH(3) uptake experiments at pH 6.0 and 9.0 (which favours NH(3) form) were carried out in order to support and substantiate our hypothesis. N source fractionation throughout the whole plant was interpreted on the basis of the relative transport of NH(4)(+) and NH(3). -- Results: Several NO(3)(-)-fed plants were consistently enriched in (15)N, whereas plants under NH(4)(+) nutrition were depleted of (15)N. It was shown that more sensitive plants to NH(4)(+) toxicity were the most depleted in (15)N. In parallel, N-deficient pea and spinach plants fed with (15)NH(4)(+) showed an increased level of NH(3) uptake at alkaline pH that was related to the (15)N depletion of the plant. Tolerant to NH(4)(+) pea plants or sensitive spinach plants showed similar trend on (15)N depletion while slight differences in the time kinetics were observed during the initial stages. The use of RbNO(3) as control discarded that the differences observed arise from pH detrimental effects. -- Conclusions: This article proposes that the negative values of delta(15)N in NH(4)(+)-fed plants are originated from NH(3) uptake by plants. Moreover, this depletion of the heavier N isotope is proportional to the NH(4)(+)/NH(3) toxicity in plants species. Therefore, we hypothesise that the low affinity transport system for NH(4)(+) may have two components: one that transports N in the molecular form and is associated with fractionation and another that transports N in the ionic form and is not associated with fractionation.

In vitro activities of natural products against oral Candida isolates from denture wearers

Background: Candida-associated denture stomatitis is a frequent infectious disease. Treatment of this oral condition is difficult because failures and recurrences are common. The aim of this study was to test the in vitro antifungal activity of pure constituents of essentials oils. -- Methods: Eight terpenic derivatives (carvacrol, farnesol, geraniol, linalool, menthol, menthone, terpinen-4-ol, and aterpineol), a phenylpropanoid (eugenol), a phenethyl alcohol (tyrosol) and fluconazole were evaluated against 38 Candida isolated from denture-wearers and 10 collection Candida strains by the CLSI M27-A3 broth microdilution method. -- Results: Almost all the tested compounds showed antifungal activity with MIC ranges of 0.03-0.25% for eugenol and linalool, 0.03-0.12% for geraniol, 0.06-0.5% for menthol, a-terpineol and terpinen-4-ol, 0.03-0.5% for carvacrol, and 0.06-4% for menthone. These compounds, with the exception of farnesol, menthone and tyrosol, showed important in vitro activities against the fluconazole-resistant and susceptible-dose dependent Candida isolates. -- Conclusions: Carvacrol, eugenol, geraniol, linalool and terpinen-4-ol were very active in vitro against oral Candida isolates. Their fungistatic and fungicidal activities might convert them into promising alternatives for the topic treatment of oral candidiasis and denture stomatitis.

Vida de D. Nuno Alvares Pereyra, segundo condestavel de Portugal, conde de Ourem Arrayolos, e Barcellos, mordomo mor de El Rey D. João o primeiro; Senhor donatário das Villas de Valença, Basto, Bouças, Baltar... : progenitor da Casa Real, pela Serenissima de Bragança em Portugal, ascendente das de Castella, França, Austria, Saboya, e dos monarcas, soberanos, principes, potentados, senhores e ilustres famílias da Europa : novamente composta pelo M. R. Padre Fr. Domingos Teixeyra, religioso eremita de Santo Agostinho, offerecida á magestade de Elrey D. João V, Nosso Senhor

Frei Domingos Teixeira, religioso da Ordem de Santo Agostinho e historiador, nasceu em Celorico de Basto entre os anos de 1675 e 1680 e morreu em 1726. Professou, em 1695, no Convento da Graça, em Lisboa e exerceu o cargo de Sacristão-Mor do Convento da Penha de França. Dedicou-se a escrever narrativas históricas, tendo sido acusado de plagiar ‘A Vida do Condestável’, de Jacinto Freire de Andrade, utilizando-se de anotações deste escritor. Trata-se da primeira edição da obra, que teve ainda uma segunda edição, custeada pelo livreiro Inácio Nogueira Xisto, na Oficina de Francisco Luis Ameno, em 1749. José dos Santos em seu ‘Catálogo da Livraria do Conde de Arneal’ nos diz que ‘a primeira edição é muito estimada e rara, sendo considerada obra de bastante merecimento para o estudo e história do Santo Condestável D. Nuno Álvares Pereira e dos seus heroicos feitos militares

Running Pace Decrease during a Marathon Is Positively Related to Blood Markers of Muscle Damage

Background: Completing a marathon is one of the most challenging sports activities, yet the source of running fatigue during this event is not completely understood. The aim of this investigation was to determine the cause(s) of running fatigue during a marathon in warm weather. Methodology/Principal Findings: We recruited 40 amateur runners (34 men and 6 women) for the study. Before the race, body core temperature, body mass, leg muscle power output during a countermovement jump, and blood samples were obtained. During the marathon (27 uC; 27% relative humidity) running fatigue was measured as the pace reduction from the first 5-km to the end of the race. Within 3 min after the marathon, the same pre-exercise variables were obtained. Results: Marathoners reduced their running pace from 3.5 6 0.4 m/s after 5-km to 2.9 6 0.6 m/s at the end of the race (P,0.05), although the running fatigue experienced by the marathoners was uneven. Marathoners with greater running fatigue (. 15% pace reduction) had elevated post-race myoglobin (1318 6 1411 v 623 6 391 mg L21; P,0.05), lactate dehydrogenase (687 6 151 v 583 6 117 U L21; P,0.05), and creatine kinase (564 6 469 v 363 6 158 U L21; P = 0.07) in comparison with marathoners that preserved their running pace reasonably well throughout the race. However, they did not differ in their body mass change (23.1 6 1.0 v 23.0 6 1.0%; P = 0.60) or post-race body temperature (38.7 6 0.7 v 38.9 6 0.9 uC; P = 0.35). Conclusions/Significance: Running pace decline during a marathon was positively related with muscle breakdown blood markers. To elucidate if muscle damage during a marathon is related to mechanistic or metabolic factors requires further investigation.
