Morphometric endoscopic study of the pharynx in patients with sleep apnea

Purpose: The aims of the study were to measure endoscopically the retrolingual pharynx during wakefulness and sleep before and after maxillomandibular advancement surgery and to quantify the changes observed. Materials and Methods: Eighteen patients with mild to severe grade obstructive sleep apnea hypopnea were evaluated during wakefulness while sitting and lying down and during induced sleep in dorsal decubitus while breathing naturally. Images of the retrolingual region of the pharynx were captured with a nasofibroscope and recorded on a DVD using the Sony Vegas 8.0 software (Sony Creative Software, Madison, WI). The images captured in greater and smaller aperture were measured with the Image J software (produced by Wayne Rasband, United States National Institutes of Health, Bethesda, MD) in linear anteroposterior and linear laterolateral areas. A correction factor was then applied to equalize the size of the images and thus compare them to one another. Results: The postoperative dimensions of the pharynx always increased significantly in all measurements compared with the preoperative ones. During induced sleep in dorsal decubitus, there was a greater gain in the area of smaller aperture (201.33%). Conclusions: The proposed method showed that the dimensions of the pharynx always increased significantly after surgery for maxillomandibular advancement, although the gain was not homogeneous in all dimensions and also varied according to state of consciousness. The greatest gain was observed in the area of smaller aperture with the patient in induced sleep, thus reducing the collapse of the pharynx. (C) 2012 Elsevier Inc. All rights reserved.

Long-term effects of oil pollution in mangrove forests (Baixada Santista, Southeast Brazil) detected using a GIS-based multitemporal analysis of aerial photographs

Oil spills are potential threats to the integrity of highly productive coastal wetlands, such as mangrove forests. In October 1983, a mangrove area of nearly 300 ha located on the southeastern coast of Brazil was impacted by a 3.5 million liter crude oil spill released by a broken pipeline. In order to assess the long-term effects of oil pollution on mangrove vegetation, we carried out a GIS-based multitemporal analysis of aerial photographs of the years 1962, 1994, 2000 and 2003. Photointerpretation, visual classification, class quantification, ground-truth and vegetation structure data were combined to evaluate the oil impact. Before the spill, the mangroves exhibited a homogeneous canopy and well-developed stands. More than ten years after the spill, the mangrove vegetation exhibited three distinct zones reflecting the long-term effects of the oil pollution. The most impacted zone (10.5 ha) presented dead trees, exposed substrate and recovering stands with reduced structural development. We suggest that the distinct impact and recovery zones reflect the spatial variability of oil removal rates in the mangrove forest. This study identifies the multitemporal analysis of aerial photographs as a useful tool for assessing a system's capacity for recovery and monitoring the long-term residual effects of pollutants on vegetation dynamics, thus giving support to mangrove forest management and conservation.

Influence of high-heeled shoes on venous function in young women

Background: Walking with high-heeled shoes is a common cause of venous complaints such as pain, fatigue, and heavy-feeling legs. The aim of the study was to clarify the influence of high-heeled shoes on the venous return and test the hypothesis that women wearing different styles of high-heeled shoes present an impaired venous return when compared with their values when they are barefoot. Methods: Thirty asymptomatic women (mean age, 26.4 years) wearing appropriately sized shoes were evaluated by air plethysmography (APG), a test that measures changes in air volume on a cuff placed on the calf, while they performed orthostatic flexion and extension foot movements and altered standing up and lying down. The test was repeated in four situations: barefoot (0 cm), medium heels (3.5 cm), stiletto high heels (7 cm), and platform high heels (7 cm). The APG values of venous filling index (VFI), ejection fraction (EF), and residual volume fraction (RVF) were divided into four groups according to heel height and compared by repeated-measures analysis of variance. Results: RVF was increased in the groups wearing high heels (stiletto and platform) compared with the barefoot group (P < .05). RVF was increased in the medium-heel group (3.5 cm) compared with the barefoot group (P < .05), and despite the lack of statistical significance, the medium-heel group showed lower values of RVF compared with the two high-heel groups. The EF parameter followed the opposite tendency, showing higher values for the barefoot group compared with the other three groups (P < .05). Values for VFI were similar in the three situations evaluated. Conclusions: High heels reduce muscle pump function, as demonstrated by reduced EF and increased RVF values. The continuous use of high heels tends to provoke venous hypertension in the lower limbs and may represent a causal factor of venous disease symptoms. (J Vasc Surg 2012;56:1039-44.)

Socio-Spatial Relationships in Dairy Cows

Farm animals may serve as models for evaluating social networks in a controlled environment. We used an automated system to track, at fine temporal and spatial resolution (once per minute, +/- 50 cm) every individual in six herds of dairy cows (Bos taurus). We then analysed the data using social network analyses. Relationships were based on non-random attachment and avoidance relationships in respect to synchronous use and distances observed in three different functional areas (activity, feeding and lying). We found that neither synchrony nor distance between cows was strongly predictable among the three functional areas. The emerging social networks were tightly knit for attachment relationships and less dense for avoidance relationships. These networks loosened up from the feeding and lying area to the activity area, and were less dense for relationships based on synchronicity than on median distance with respect to node degree, relative size of the largest cluster, density and diameter of the network. In addition, synchronicity was higher in dyads of dairy cows that had grown up together and shared their last dry period. This last effect disappeared with increasing herd size. Dairy herds can be characterized by one strongly clustered network including most of the herd members with many non-random attachment and avoidance relationships. Closely synchronous dyads were composed of cows with more intense previous contact. The automatic tracking of a large number of individuals proved promising in acquiring the data necessary for tackling social network analyses.

Importancia de la imago Dei en la comprensión de la doctrina de los trascendentales en Tomás de Aquino

El presente trabajo se ocupa de la importancia que tiene el concepto de imago Dei presente en Santo Tomás de Aquino en función de una adecuada comprensión de la doctrina de los trascendentales. Esto implicará considerar el concepto de imagen de Dios en el hombre para luego entender cómo es que a la luz de este concepto Tomás lee al Estagirita, cuyos textos cita como argumento de autoridad en su consideración de los trascendentales, de una manera que renueva y expande la significación de los textos aristotélicos. Esto también permitirá percibir con más precisión el significado de las expresiones utilizadas por Tomás para designar a los trascendentales, en especial cuando se refiere a la verdad y al bien.

Aproximación al monacato occidental en la Edad Media

Monasticism was not born nor grew up in contraposition to scholasticism. Both of them express the truth and unity of religious life. In this paper, the Author analyses the cases of a monk and a scholar, Bernardus of Claraval and Petrus Abelardus, respectively, by means of two of their major works: Commentary on The Song of Songs and Preface to the Commentary on the Letters of Saint Paul. Finally, a brief summary concerning longing for heaven in texts of Medium Ages is included.

Filosofía y vida filosófica

El propósito de este escrito es el de recordar que la filosofía es ante todo una manera de vivir en la cual la contemplación ocupa el lugar principal. El impulso originario de la vida filosófica es el amor a la verdad y no el odio por las injusticias, y esto descalifica las pretensiones de saber filosófico de algunas corrientes de pensamiento.

Metodología del racionalismo crítico y cambios teóricos : el caso de la metrología

La metodología del racionalismo crítico permite ajustar una teoría cuando aparecen problemas. En metrología surgieron nuevas exigencias para las mediciones que provienen de los mercados globalizados. Esa situación está provocando el desplazamiento de la concepción tradicional por la teoría de incertidumbre. Este trabajo examinó ese cambio, evaluando ambas teorías y determinando sus aproximaciones a la verdad y los motivos para cambiarlas. Se realizó un análisis lógico de la bibliografía especializada para determinar la preferencia teórica. Se concluyó que la teoría de la incertidumbre es más confiable, porque define mejor mensurando y condiciones de medición. Las certificaciones de trazabilidad documentan las calibraciones periódicas de los instrumentos de medición, garantizando la verdad como criterio regulador, para que mantengan su validez y confiabilidad. Además, el racionalismo crítico permitió evaluar este cambio en metrología como una evolución en el mundo del conocimiento objetivo.

Los conceptos de verdad y falsedad en Filoctetes de Sófocles

El presente trabajo pretende exponer las particularidades que exhiben los términos (...), verdad, y (...), falsedad, en Filoctetes de Sófocles. Merced al análisis etimológico, morfológico y semántico de dichos términos, de las relaciones que se establecen entre ellos y de su disposición en la tragedia, se busca destacar la manera en que el texto trágico mismo pone en evidencia la naturaleza de ambos conceptos como constructos humanos, arti´Çücios del lenguaje no sólo parciales sino también relativos, subordinados a contextos de enunciación transitorios.

Espacios escénicos, geográfico y metafórico en Helena de Eurípides

En los primeros tres versos de Helena, Eurípides presenta las dos principales novedades argumentales respecto del tema: la esposa de Menelao se presenta ante los ojos de los espectadores en el ignoto Egipto y el personaje no es la mujer fatal de tantas obras, la princesa dominante y altanera orgullosa de su belleza y de la predilección de la que goza, sino que se ha convertido en una humilde suplicante, postrada ante una tumba para pedir la protección de los dioses, ya que quiere mantenerse intacta ante los reclamos matrimoniales de Teoclimeno, el nuevo rey egipcio. Geografía y escenografía jugarán un papel preponderante en la intencionalidad poética, y en este contraste de espacios y de tiempos cargados de sentido metafórico se terminará de dibujar el sentido de la tragedia: vida y muerte, juventud y vejez, verdad y apariencia, nombre y realidad; pero también la isla de Faros que está frente a Egipto, las islas en las que naufragaron tantos héroes griegos y la isla situada en frente de Atenas; también el pasado mítico de Helena y el futuro cultual de Atenas: todo se divide y contrasta armónicamente en Helena.
