The AirView Study: Comparison of Intubation Conditions and Ease between the Airtraq-AirView and the King Vision.

We conducted a study assessing the quality and speed of intubation between the Airtraq with its new iPhone AirView app and the King Vision in a manikin. The primary endpoint was reduction of time needed for intubation. Secondary endpoints included times necessary for intubation. 30 anaesthetists randomly performed 3 intubations with each device on a difficult airway manikin. Participants had a professional experience of 12 years: 60.0% possessed the Airtraq in their hospital, 46.7% the King Vision, and 20.0% both. Median time difference [IQR] to identify glottis (1.1 [-1.3; 3.9] P = 0.019), for tube insertion (2.1 [-2.6; 9.4] P = 0.002) and lung ventilation (2.8 [-2.4; 11.5] P = 0.001), was shorter with the Airtraq-AirView. Median time for glottis visualization was significantly shorter with the Airtraq-AirView (5.3 [4.0; 8.4] versus 6.4 [4.6; 9.1]). Cormack Lehane before intubation was better with the King Vision (P = 0.03); no difference was noted during intubation, for subjective device insertion or quality of epiglottis visualisation. Assessment of tracheal tube insertion was better with the Airtraq-AirView. The Airtraq-AirView allows faster identification of the landmarks and intubation in a difficult airway manikin, while clinical relevance remains to be studied. Anaesthetists assessed the intubation better with the Airtraq-AirView.

Una propuesta de la integración psicocorporal a través de la técnica Alexander y la danza movimiento terapia

Este trabajo es una propuesta de integración de la Técnica Alexander y la Danza Movimiento Terapia. Partiendo de la realidad de que ambas técnicas tienen como objetivo final la integración de la dimensión de la psique, del cuerpo y de la emoción, para restaurar el equilibrio integral del ser humano que como consecuencia aporta un estado de salud al individuo. Cada una de ellas se posiciona sobre un camino diferente hacia la curación, aunque comparten muchas bases en común. Una de ellas trata del aprendizaje de un método: la Técnica Alexander, y la otra es una forma de psicoterapia para realizar un proceso terapéutico: la Danza Movimiento Terápia. Una se focaliza en la reeducación del uso psicofísico del individuo y en su interacción con el mundo interno y externo (TA) y el otro en la expresión y despliegue psico / corporal / emocional para la transformación y el desarrollo personal, y la curación del trauma (DMT). Como cada una de ellas ha desarrollado un aspecto más profundamente que otro, en el caso de la TA: la estructura psicofísica primaria y estructural orgánica, y la DMT: la emoción: su expresión y capacidad para la transformación. Y es estos aspectos más desarrollados que pueden enriquecer y desarrollar a la otra. Este texto aporta un estudio comparativo entre ambos métodos, los objetivos y la teoría que comparten como los aspectos en los que divergen. Finalmente se propone una hipótesis de integración de la TA, como técnica base de formación psicocorporal del estudiante dentro de un programa de formación de la DMT, y la DMT como técnica psicoterapéutica de acompañamiento de los estudiantes en formación de profesores de la TA.

Genomic analysis of the blood attributed to Louis XVI (1754-1793), king of France.

A pyrographically decorated gourd, dated to the French Revolution period, has been alleged to contain a handkerchief dipped into the blood of the French king Louis XVI (1754-1793) after his beheading but recent analyses of living males from two Bourbon branches cast doubts on its authenticity. We sequenced the complete genome of the DNA contained in the gourd at low coverage (similar to 2.5x) with coding sequences enriched at a higher similar to 7.3x coverage. We found that the ancestry of the gourd's genome does not seem compatible with Louis XVI's known ancestry. From a functional perspective, we did not find an excess of alleles contributing to height despite being described as the tallest person in Court. In addition, the eye colour prediction supported brown eyes, while Louis XVI had blue eyes. This is the first draft genome generated from a person who lived in a recent historical period; however, our results suggest that this sample may not correspond to the alleged king.

Interespecific variation in the composition of volatile oils from the leaves of Swietenia macrophylla King (Meliaceae)

The volatile oils from leaves of five Brazilian specimens of Swietenia macrophylla King (Meliaceae) collected in three different Amazon Rainforest Conservation Areas in the States of Mato Grosso, Pará, and Rondônia were extracted and analyzed by GC and GC/MS. The oils showed to be composed by terpenoids, majority hydrocarbon sesquiterpenes, being germacrene D (20.5-46.8%) and bicyclogermacrene (8.3-11.1%) the main components. Besides these derivatives, only α-cubebene, β-caryophyllene, β-gurjunene and γ-cadinene were detected in all of the analyzed samples. This analysis indicated a great diversity of constituents in the oils obtained from specimens collected in these regions, which could be associated to the different susceptibility in the attack of H. grandella in S. macrophylla cultures.

Desinfestação e germinação in vitro de sementes de mogno (Swietenia macrophylla King)

O presente trabalho teve como objetivos desenvolver técnicas de regeneração in vitro a partir de segmentos de epicótilo, epicótilo invertido e explantes foliares provenientes de plântulas de mogno (Swietenia macrophylla) germinadas em meio de cultura; e determinar a melhor concentração e tempo de exposição das sementes ao agente desinfestante, bem como a melhor posição de semeadura para germinação. As sementes foram desinfestadas, após a retirada do tegumento, em soluções com hipoclorito de sódio nas concentrações de 0; 2,5; e 5,0% (v/v), mantidas embebidas por 10, 20, 30 e 40 minutos e colocadas no meio em duas posições, sendo a posição 1 com a concavidade da parte achatada voltada para cima e na posição 2, com a concavidade da parte achatada voltada para baixo. Após a semeadura, foram mantidas em sala de crescimento com temperatura de ±26 ± 2 º C e escuro contínuo. O delineamento utilizado foi o inteiramente casualizado, em esquema fatorial 3 x 4 x 2 (níveis de hipoclorito x tempos de embebição x posição de semeadura), totalizando 24 tratamentos com três repetições. As avaliações de germinação e contaminação por microrganismos ocorreram aos 12, 18, 24 e 30 dias. O melhor tratamento foi a desinfestação das sementes embebidas em 2,5 e 5% de hipoclorito de sódio por 30 e 20 minutos, respectivamente, as quais foram colocadas na posição 2, pois apresentaram a maior germinação (48%) e baixa contaminação (15 e 10%, respectivamente). Quanto à posição, houve diferença significativa aos 24 e 30 dias após a semeadura, com as maiores médias nas sementes colocadas na posição 2.

Avaliação do plantio homogêneo de mogno, Swietenia macrophylla King, em comparação com o plantio consorciado com Eucalyptus urophylla S. T. Blake, após 40 meses de idade

Na Amazônia, plantios de mogno têm sido limitados por ataques de Hypsiphylla grandella Zeller. No entanto, plantios em áreas urbanas em Brasília vêm apresentando bom desenvolvimento. O objetivo deste trabalho foi observar o comportamento do mogno em plantios homogêneo e consorciado. Para isso foi instalado um experimento na Fazenda Água Limpa, da Universidade de Brasília (UnB), Distrito Federal, com dois tratamentos: plantio homogêneo e plantio misto com eucalipto. O primeiro consistiu no plantio homogêneo de mogno e o segundo, consorciado com eucalipto. Foram medidas as variáveis altura aos 7, 12, 15, 24, 28, 36 e 40 meses de idade e diâmetro aos 7, 24, 28, 36 e 40 meses. O delineamento utilizado foi inteiramente ao acaso, em esquema de parcelas subdivididas, sendo os tratamentos as parcelas e o tempo, as subparcelas. A altura média aos 40 meses do consórcio foi de 2,28 m e do homogêneo, de 3,45 m, sendo as alturas máximas, respectivamente, de 4,15 e 5,17 m. O diâmetro médio também foi maior no tratamento homogêneo do que no consórcio (4,08 e 6,92 cm, respectivamente). A mortalidade situou-se em torno de 20%, tanto no plantio homogêneo quanto no consorciado, não havendo diferenças significativas. O ataque das larvas de H. grandella foi menor no plantio consorciado, indicando que o eucalipto serve como barreira física, diminuindo o ataque da praga, porém a competição de ambos ocasionou menor crescimento do mogno.

Conservative nutrient use by big-leaf mahogany (Swietenia macrophylla king) planted under contrasting environmental conditions

We analyzed the nutritional composition and isotope ratios (C and N) of big-leaf mahogany (Swietenia macrophylla King) leaves in plantations established on contrasting soils and climates in Central America (State of Quintana Roo, Yucatán, México) and South America (State of Pará, Brazil). The objective was to determine the adaptability of this species to large differences in nutrient availability and rainfall regimes. Nutrient concentrations of leaves and soils were determined spectrophotometrically, and isotope ratios were measured using mass spectrometric techniques.In Pará soils were sandier, and acidic, receiving above 2000 mm of rain, whereas in Quintana Roo soils were predominantly clayey, with neutral to alkaline pH due to the underlying calcareous substrate, with about 1300 mm of rain. Leaf area/weight ratio was similar for both sites, but leaves from Quintana Roo were significantly smaller. Average N and K concentrations of adult leaves were similar, whereas Ca concentration was only slightly lower in Pará in spite of large differences in Ca availability. Leaves from this site had slightly higher P and lower Al concentrations. Differences in water use efficiency as measured by the natural abundance of 13C were negligible, the main effect of lower rainfall in Quintana Roo seemed to be a reduction in leaf area. The N isotope signature (δ15N) was more positive in Pará than in Quintana Roo, suggesting higher denitrification rates in the former. Results reveal a calciotrophic behavior and a remarkable capacity of mahogany to compensate for large differences in soil texture and nutrient availability.
