    Full Text Available Las 106 especies y subespecies que se mencionan en este trabajo constituyen una lista preliminar de la fauna ornitológica de la región más meridional de Colombia, esto es, la ribera izquierda del rio Amazonas entre la boca del Atacuari y la población de Leticia, capital de la Intendencia del Amazonas, en el extrema sur del territorio que en Colombia llamamos comúnmente "Trapecio Amazónico". La lista esta compuesta principalmente por las colecciones hechas en Leticia y la Isla Ronda par el senor Carlos Lehmann en octubre y noviembre de 1939 y par uno de nosotros -José I. Borrero- en Leticia, Isla Mocagua, Hamacayacu y Loretoyacu en marzo y abril del presente año. Los ejemplares que mencionamos en dicha lista se hallan en la colección ornitológica del Instituto de Ciencias Naturales.

  2. Análisis multivariado del dimorfismo sexual en doce etnias del Gran Chaco

    Marcellino, Alberto José

    2002-01-01

    Full Text Available Se ensaya el cálculo de las distancias morfológicas para cuantificar el dimorfismo antropométrico sexual en distintas etnias aborígenes. Paralelamente se investiga: a- el grado de las diferencias entre los dimorfismos de los segmentos cefálico y postcefálico; b- los resultados con distintas combinaciones de variables, redundantes y no redundantes; c- la magnitud de participación de "forma" y "tamaño" en la distancia "total". Las distancias se calcularon mediante los algoritmos de Penrose (1954. El material utilizado fueron los datos antropométricos (inéditos correspondientes a 890 varones y 844 mujeres, obtenidos por Jehan A.Vellard, en 12 etnias del Gran Chaco Sudamericano. Las conclusiones indican: 1 la sensibilidad discriminatoria del procedimiento; 2 el segmento corporal postcefálico proporciona valores de dimorfismo notoriamente más altos que el cefálico en 11 de las 12 etnias investigadas, siendo los Ayoreo la única en que ambas distancias resultan iguales; 3 el dimorfismo sexual antropométrico está dado por el componente "tamaño" más que por el componente "forma", en proporciones cuyo rango aproximado es de 3:1 a 1:0; 4 se indica la combinación más apta para calcular el dimorfismo somatométrico "global" (cefálico+postcefálico que consta de 14 dimensiones, sin redundancia; 5 se plantea la hipótesis de que la razón dimorfismo cefálico/dimorfismo corporal postcefálico se vincularía, en relación inversa, al grado de mestización del grupo.

  3. Evolución del dimorfismo sexual en la estatura adulta de la etnia chorote

    Directory of Open Access Journals (Sweden)

    Ferrarini, Stella Ofelia

    2007-01-01

    Full Text Available Mientras que en todas las sociedades conocidas las mujeres son más bajas que los hombres, la relación entre el promedio de la altura masculina y la femenina es variable. El dimorfismo sexual en la especie humana puede ser considerado como una parte del sistema adaptativo total, con componentes físicos y también energéticos y conductuales. Se estudian los cambios temporales en la expresión del dimorfismo sexual en dos muestras de individuos adultos de la etnia Chorote. Los datos de un total de 198 individuos se organizaron por sexo en cuatro series que se corresponden con dos momentos temporales sucesivos. Para cada una de ellas se calcularon media, DS y CV. Se confrontaron las series temporales mediante el cálculo de las diferencias de las medias: a en valor absoluto; b en índice de dimorfismo; c en la relación estatura masculina/estatura femenina; y finalmente d la significación de las diferencias a través de la prueba “t”. Además, se analizaron las distribuciones internas de cada serie con datos agrupados por clases diferentes para cada sexo. Los resultados ponen de manifiesto una tendencia hacia la concentración mayoritaria en la clase estatura mediana y expresan la existencia de dimorfismo en distintos momentos históricos, con el aumento del mismo a expensas del aumento en la estatura masculina y el mantenimiento de la femenina; de manera que las diferencias se transforman de no significativas en significativas en las series más recientes. Estos resultados respaldan la hipótesis de que los hombres tienden a estar algo menos canalizados en su desarrollo, respecto al tamaño, que las mujeres. Para éstas la reproducción exitosa plantea demandas fisiológicas más exigentes sobre el tamaño, mientras para los hombres las variaciones en tamaño, excepto cuando ponen en peligro la supervivencia o la selección sexual, pueden ser consideradas irrelevantes para el éxito reproductivo.

  4. Etnia y tradición religiosa: adoraciones nortecaucanas del Niño Dios

Son mostrados también detalles de la organización social que incluye la estrutura de clanes con sus jerarquías. Se describen las distintas asociaciones indígenas de la región que consiguieron forjar una conciencia en la población del municipío, en donde actualmente 90,0% se asume como perteneciente a grupos étnicos indígenas. Con respecto a la cultura, se detacan las prácticas de cura y auto-cuidado proporcionadas por los “benzederos”. La estructura de sanidad pertenece al polo de Sta. Isabel, con un hospital y una unidad básica de salud, siendo que el Distrito Especial Indígena de Salud fue ampliado para garantizar la cobertura al medio Rio Negro. Sin embargo, se señalan las dificultades generadas por las enormes distancias de desplazamiento.

  11. Impacto económico y ambiental del uso del gas natural en la generación de electricidad en El Amazonas: Estudio de caso

    Directory of Open Access Journals (Sweden)

    Wagner Ferreira Silva

    2015-01-01

    Full Text Available Las transformaciones que tienen lugar en el Amazonas, considerado "el pulmón del planeta", tienen un significado especial, no solamente por el ahorro de energía, sino también por su impacto ambiental debido a la reducción de gases de efecto invernadero. Desde el año 2010, en Manaos la capital del Amazonas en Brasil, muchas centrales termoeléctricas están sustituyendo el fueloil por gas natural para la generación de energía. Debido a la gran reserva de gas natural en la región, este combustible se ha convertido en la mejor opción para las centrales eléctricas construidas en este lugar. En el presente trabajo se analiza el impacto técnico económico y medio ambiental de la sustitución del fueloil por el gas natural en la planta de generación de energía analizada.

  12. Nuevo registro del loro frente blanca (Amazona albifrons para la Isla de Cozumel, Quintana Roo, México

    Directory of Open Access Journals (Sweden)

    Alexis Herminio Plasencia Vázquez

    2012-01-01

    Full Text Available Reportamos, por primera vez en la literatura científica, al loro frente blanca (Amazona albifrons como especie introducida en áreas urbanas de la Isla de Cozumel, Quintana Roo, durante el trabajo de campo realizado en el mes de abril de 2011. Su presencia sólo en áreas urbanas de la isla, la capacidad de la especie para poder vivir con éxito en áreas urbanas, la abundancia de árboles frutales y su uso como mascota por los isleños nos permite sugerir que los individuos registrados son resultado de escapes o fueron liberados por sus dueños. Es probable que las condiciones sean favorables para el establecimiento de una población dentro del poblado de San Miguel de Cozumel, lo que debe monitorearse en el futuro.

  13. Visiones jesuíticas del Amazonas en la Colonia: de la misión como dominio espiritual a la exploración de las riquezas del río vistas como tesoro

    Fernando Torres-Londoño

    2012-01-01

    Full Text Available Este artículo examina las elaboraciones textuales de jesuitas españoles y portugueses en relación con el río Amazonas durante los siglos XVII y XVIII. Los jesuitas de las misiones de Maynas, establecidas entre diversos tributarios del río Amazonas, entendieron sus misiones como la mejor forma de garantizar el dominio español en la región. El fracaso de este modelo aproximó a los misioneros de Maynas a la visión de los jesuitas portugueses del Pará, entre ellos el padre João Daniel, que vieron el río Amazonas como una gran fuente de riqueza, base para una ocupación sustentada en el poblamiento y la agricultura.

  14. SABERES TRADICIONALES SOBRE EL USO Y MANEJO DEL P+CAÁJKE EN LA ETNIA BORA COMUNIDAD DE PROVIDENCIA Y SU RELACIÓN CON LA EDUCACIÓN PROPIA

    2013-07-01

    Full Text Available Investigación realizada en el río Igaraparaná, Amazonia colombiana, con la comunidad indígena bora de Providencia, en los clanes Ts+ts+vemuna, Boaj+, +vamuje. El propósito fue documentar los saberes tradicionales en torno al significado, uso y manejo del p+caájke y realizar una descripción etnobotánica de la planta. La metodología es de corte hermenéutico, con una técnica etnográfica, que implicó fases de descripción, categorización e interpretación. Como resultado se encontró que los saberes, uso y manejo del p+caájke se centran en el concepto de abundancia, constituido por ocho dimensiones relacionadas con la prevención de males, mayor producción de los frutos de la chagra, valores femeninos, trabajo, alimento, espiritualidad, salud, armonía y variedad. Con base en esta caracterización, se realizó una descripción de los procesos educativos propios de la etnia bora y se hizo una propuesta pedagógica, de carácter intercultural, que busca generar un diálogo de saberes, entre los conocimientos ancestrales en torno al p+caájke y sus significados, con el conocimiento escolar, específicamente en el grado tercero de primaria.

  15. ¿Por qué las caras de otras etnias nos parecen iguales?

    Beatriz Martín-Luengo

    2013-11-01

    Full Text Available ¿Por qué a veces somos incapaces de distinguir entre personas de otra etnia? Una razón puede ser porque no recordamos de la misma manera las caras dependiendo de la etnia a la que pertenecen. Actualmente existen varias teorías que explican por qué nuestra memoria es mejor para caras de nuestra propia etnia, como son las teorías del procesamiento perceptivo de caras, las teorías basadas en la cognición social del procesamiento de caras y las teorías híbridas entre las perceptivas y las basadas en cognición social. En este artículo repasamos y explicamos a grandes rasgos cada uno de estos acercamientos teóricos.

    Full Text Available Se realizó un reconocimiento taxonómico y estimación de la densidad en el ensamblaje de rotíferos en el lago Largo, del sistema de lagos Yahuarcaca, en la ribera colombiana del río Amazonas, a partir de muestreos en las fases hidrológicas de aguas bajas, ascenso y descenso. Se identificaron 68 especies, 28 de ellas son nuevos registros para ambientes colombianos. Se encontró aumento en la riqueza en las épocas de ascenso y descenso, siendo mayor en la zona litoral respecto de la limnética, y la tendencia a mayor similitud taxonómica entre ambas zonas en el periodo de aguas bajas, debido al mínimo desarrollo de macrófitas en esta fase y la consecuente menor heterogeneidad espacial. Se observó el predominio de rotíferos con trofi adaptados para moler y triturar partículas (maleado y maleorramado en las épocas de aguas bajas (Brachionus ahlstromi y descenso (Filina saltator y en la época de ascenso de Polyarthra vulgaris, con trofi adaptado para perforar y succionar fluidos de algas y otros organismos (virgado y apéndices que favorecen la rápida natación. En general, se establecieron posibles relaciones entre la riqueza y la densidad de rotíferos con cambios en características como el desarrollo de vegetación acuática en el litoral, profundidad del lago, nivel de conectividad con los otros lagos del sistema Yahuarcaca, influencia de aguas blancas del Amazonas y negras de origen local, potenciales recursos nutricionales y depredadores, y posible efecto de arrastre por la corriente.

    2016-01-01

    Full Text Available La investigación analizó los impactos ambientales causados por las actividades humanas en la microcuenca del río Parafuso en el municipio de Moju en el Estado de Pará (Brasil. Los datos fueron obtenidos mediante herramientas de geoprocesamiento, investigación documental, cuestionarios, entrevistas semi estructuradas, observación directa y la cartografía participativa. Los resultados mostraron que las actividades antropogénicas y de crecimiento de la población sin planificación, combinada con el uso excesivo de los recursos naturales, causan un deterioro grave en los medios físico, biótico y antrópico en la cuenca del río Parafuso. Las fuentes identificadas en esta cuenca son difusas, temporales y han cambiado. La jerarquía del río en el sistema de drenaje es de segundo orden. La mayoría de los impactos ambientales identificados son de de carácter adverso, de gran importancia, de alta magnitude y de duración larga. El medio fisico es el más afectado. En orden de magnitud e importancia, la agricultura es la actividad que hace los principales impactos adversos y duraderos sobre el ambiente físico y el ambiente biológico.

  19. EL PROCESO DE ENDOCULTURACIÓN DE LA ETNIA TICUNA:ESTRATEGIA DE TRASMISIÓN VÍA GENERACIONAL ACERCA DE LA NOCIÓN DE AMBIENTE NATURALISTA

    Directory of Open Access Journals (Sweden)

    Laura Marcela Trujillo Castro

    2013-06-01

    Full Text Available El proceso de endoculturación ha permitido que las costumbres y conductas de una cultura estén presentes desde las generaciones antiguas hasta las actuales. Por consiguiente, el presente artículo se centra en exponer la indagación de hábitos, conductas, rutinas y celebraciones, para dar cuenta de dicho proceso en la etnia ticuna. El ejercicio investigativo de corte etnográfico realizado en dicha comunidad de Puerto Nariño y Leticia (Amazonas, Colombia, permitió caracterizar la relación entre endoculturación y la noción de ambiente naturalista de la etnia por medio de la indagación, análisis y reflexión de las dinámicas de trasmisión generacional. En consecuencia,se exponen los resultados y discusiones de las manifestaciones de dicho proceso. Los instrumentos de recolección de la información corresponden a la realización de entrevistas semiestructuradas con preguntas abiertas, destacando aspectos de la vida, sobre la noción y apropiación del ambiente, para identificar la diferencia con el término naturaleza. Finalmente, durante la salida de campo al Trapecio amazónico, realizada en noviembre de 2012, se interactúo con diferentes personas pertenecientes a dicha comunidad, con lo cual se identificó que el proceso de endoculturación está presente en la etnia, teniendo en cuenta que las prácticas de dicho grupo se enmarcan en el cuidado, aprendizaje, interacción y relaciones cotidianas con la naturaleza, desde las personas mayores hasta los integrantes más jóvenes. También, se evidenció que la concepción de ambiente naturalista se relaciona con el valorintrínseco del ambiente, es decir, más allá de los recursosque la naturaleza entrega.

    Full Text Available En el artículo se describen las características de las prácticas de crianza en una comunidad mayo y se realiza un análisis documental del Modelo de Educación Inicial no Escolarizada del CONAFE. Ello con la finalidad de contrastar los resultados de la práctica de crianza con las competencias esperadas de los padres y niños que asisten al programa y con base en ello, identificar la eficacia de la implementación del programa para la reproducción social en la etnia mayo. Participaron cincuenta madres y niños de la comunidad indígena mayo "El Júpare" ubicada en el municipio de Huatabampo, al sur de Sonora. Los instrumentos utilizados fueron Índice de Estrés Parental (Abidin, 1990, Interacción Padre-Hijo-Madre (Peña, 2004, Estimulación del Niño en el Hogar (Caldwell y Bradley, 1967 y Escala del Desarrollo Integral del niño (Atkin, 1987. En la evaluación del desarrollo, 54% de los niños presentan un desarrollo normal, 26% rrollo en riesgo y en 20% se detectan problemas. El programa de Educación Inicial no Escolarizado requiere de modificaciones sustantivas para responder a las prácticas de crianza que se desarrollan en la etnia mayo.

    Full Text Available Objetivos. Identificar los factores asociados al cumplimiento del control de crecimiento y desarrollo (CRED del niño menor de 1 año, en establecimientos de salud del Ministerio de Salud (MINSA de Amazonas, Loreto y Pasco, Perú, de enero a diciembre de 2012. Materiales y métodos. Estudio de casos-controles pareados. Se definió como caso al niño que no completó 11 controles CRED hasta cumplir 11 meses de edad, y como control, aquel niño con 11 controles CRED para la misma edad. La relación entre cada factor con el cumplimiento del CRED se estableció mediante la prueba de McNemar (p<0,05 y como medida de fuerza de asociación el odds ratio (OR para muestras pareadas (IC 95%. Resultados. Siete factores, luego del control de diversas variables, están asociados significativamente al cumplimiento de los controles CRED. El factor común, en las tres regiones, fue que se dejó de atender alguna vez al niño; lo que se asoció, de tres a cinco veces, con la chance de no cumplir los controles CRED en Loreto y Pasco, mientras que en Amazonas se presentó un efecto opuesto (OR 0,58; IC 95% 0,41-0,81. Conclusiones. Existen factores relacionados con el cumplimiento del CRED en niños menores de un año que varían según región. Uno de los principales obstáculos identificados son las múltiples funciones que deben desarrollar los profesionales que laboran en CRED, por lo que se pierden oportunidades de atención al niño; en tal sentido debe garantizarse la dotación suficiente de personal e inculcar permanentemente el buen trato que debe brindarse a los pacientes.

    Full Text Available La alta prevalencia de problemas alimentarionutricionales y el bajo impacto de los programas alimentarios, principalmente porque se ha ignorado la cosmovisión de este pueblo, justifica la recuperación de la cultura de consumo alimentario-nutrimental de la etnia Wixarika en México. La investigación tiene el objetivo de identificar elementos para construir un modelo de alimentación y nutrición sustentable, intercultural y participativo que articule modernidad y tradiciones ancestrales. Métodos: Se utiliza la metodología de investigación acción participativa sustentada en la epistemología sociocrítica con las técnicas de entrevista en profundidad y etnografía participante. La investigación se realizó en la comunidad Wixarika de Santa Catarina Cuexcomatitlan, en el municipio de Mezquitic, Jalisco, México. Resultados: El consumo alimentario del pueblo Wixarika tiene un sentido religioso, en el que el maíz es el articulador principal de la cosmovisión alimentaria. La base de la producción y el consumo alimentario está formada por la tríada: maíz, frijol y calabaza, con agregados de jitomate y chile, así como de la recolección de alimentos del entorno ecológico como hongos, quelites y nopales, alimentos que al producirse y consumirse en cantidades suficientes y combinados adecuadamente pueden permitir una alimentación correcta para esta etnia. Conclusiones: La alimentación constituye un elemento central en la construcción de la cosmovisión del pueblo Wixarika, representaciones y significados que deben integrarse para la construcción de un modelo que garantice la seguridad alimentario-nutrimental de esta etnia.

Se realizó la toma medidas antropométricas, dosaje de hemoglobina a ambos grupos y finalmente una encuesta de consumo de alimentos a una submuestra de 290 hogares. Resultados: La prevalencia de desnutrición crónica en niños fue de 33,4%. Se encontró asociación estadística entre el distrito de residencia y la desnutrición crónica en niños. La prevalencia de anemia fue de 76,5%. El 89% de las MEF presentaron un IMC ideal, sin embargo, la talla promedio de la mujer aguaruna fue de 148 cm. La prevalencia de anemia en MEF fue de 50,2%. Se listaron más de 100 alimentos locales y foráneos que forman parte de la dieta de las familias aguarunas; sin embargo, sólo se consume diariamente la yuca y plátanos; y con alguna frecuencia semanal el arroz, la carachama, gusano, huevo de gallina y verduras como la chonta y sachaculantro. Conclusiones: La evaluación nutricional indica un déficit nutricional para los niños y la deficiencia de hierro expresada en anemia afecta a la mitad de las MEF y a dos de cada tres niños. Esta situación podría atribuirse, entre otras causas al consumo de una dieta basada principalmente en yuca y plátanos con escasa presencia de alimentos de origen animal.

    Full Text Available El ecoturismo es visto como oportunidad para el desarrollo, la conservación y la generación de beneficios para las comunidades; bajo esta perspectiva, Parques Nacionales en el año 2004 entrega en concesión los servicios ecoturísticos del PNN Amacayacu, proceso que ha traído interrogantes e inconformidades. Esta investigación busca analizar la visión que tienen las comunidades del PNN Amacayacu sobre los beneficios derivados del ecoturismo, mediante una metodología cualitativa que establece la percepción de la comunidad frente al problema. Los resultados muestran al ecoturismo como un modelo exógeno de desarrollo que genera beneficios, pero también impactos en los modos de vida y la cultura local; muestran también que, más allá de los beneficios monetarios, existen otros como la participación en la toma de decisiones que son más valiosos para las comunidades. Finalmente, muestra la relevancia de cuestionarse sobre cuál es el tipo de desarrollo al que se le apunta desde el ecoturismo y la importancia de que sean las mismas comunidades quienes lo definan.

    Full Text Available A chemical and biological preliminary study of the species Vismia cayennensis, collected in the Amazonas state, Venezuela. The antibacterial test of plant bark extract showed significant inhibition in Escherichia coli, Shigella sp and Staphylococcus aureus. In addition, three of the five soluble fractions of different polarity solvents, specifically those of chloroform, acetone and water, maintained moderately active against Shigella sp strain. The hydroalcoholic extract of the plant and the fraction soluble in chloroform, exhibited a significant antiinflammatory effect. Cytotoxicity tests performed by the methods of (3-(4,5-dimetiltiazol-2-yl-5-(3-carboximetoxifenil-2-(4-sulfophenyl-2H-tetrazolium/phenazine methosulfate of (MTS/PMS and sulforhodamine B , revealed that only has water soluble cytotoxic effect. Additionally, a study phytochemical obtained information on the presence of some families of secondary metabolites such as flavonoids, saponins, tannins, polyphenols, anthraquinones, triterpenes and sterols. It can be inferred that the stem bark of the plant V. cayennensis, is a promising source of bioactive secondary metabolites

    Full Text Available Este artigo fundamenta-se em uma etnografia sobre práticas de saúde na aldeia Kwatá, dos Índios Munduruku, localizados no Rio Canumã, no município de Borba, Amazonas, Brasil. Essas práticas de saúde extrapolam o circuito biomédico de atenção e abrangem redes de atores sociais que podem ser descritos como participantes de um “campo religioso” de atenção às enfermidades. Verificou-se que o papel da autoatenção nos processos de saúde e doença é fundamental para a constituição desse campo, no qual se destacam forças convergentes e antagônicas do xamanismo, do cristianismo, da umbanda, do espiritismo kardecista e da biomedicina. Os dados levantados apontam que essas redes de relações sociais projetam-se para além dos limites da terra indígena, para espaços rurais e urbanos, e frequentemente estabelecem diálogos interétnicos. Os itinerários terapêuticos acompanhados indicam a heterogeneidade das práticas de saúde desenvolvidas pelos Munduruku com destaque à autoatenção, à atuação política e à inserção econômica no cenário local e regional.

MATERIAL Y MÉTODOS: Estudio transversal, realizado entre 1997 y 1999, en Santiago y la zona centro-sur de Chile, en 351 escolares indígenas y 531 no indígenas, y sus padres, provenientes de comunas de tres niveles de vulnerabilidad social: muy alta (pobreza, mediana y muy baja. Escolar indígena era el que tenía sus cuatro apellidos mapuches, el no indígena tenía sus cuatro apellidos de origen chileno-español. La estatura se comparó en medidas estandarizadas (puntaje Z utilizando como referencia la medición del cambio nutricional propuesta por la Organización Mundial de la Salud. Se estimaron las diferencias de medias de estatura padres-hijos con análisis de varianza y se determinó el origen de tales diferencias al aplicar el procedimiento de Scheffe. RESULTADOS: Los progenitores en ambas etnias aumentaron sus promedios de estatura al mejorar las condiciones sociales, excepto las madres indígenas que no presentaron incremento significativo. Los padres de la muy alta vulnerabilidad midieron 4 cm menos que los de la muy baja vulnerabilidad y las madres 2 cm menos (p<0.001. En los escolares indígenas hay una gradiente positiva de estatura a medida que mejoran las condiciones sociales (p<0.001, no así en los no indígenas. Al comparar la estatura de progenitores e hijo(as se observa que los escolares presentaron un índice talla/edad mayor que sus padres (p<0.01, especialmente los escolares indígenas que en promedio tuvieron 1.4 puntajes Z más que sus padres.

    Full Text Available La especie Aedes albopictus es un eficiente vector del dengue en Asia y, posiblemente, de otros arbovirus incluyendo la fiebre amarilla y la encefalitis. En la ultima década se ha extendido la distribución de A. albopictus a las Américas. En la ciudad de Tabatinga, Brasil, muy cerceide la frontera con Colombia, se ha informado la presencia de esta especie en 1996 y, posteriormente, en octubre de 1997. En marzo de 1998, en desarrollo de un e&udio sobre enfermedades tropicales realizado por el Programa de Estudio y Cotítrol de Enfermedades Tropicales, PECET, de la Universidad de Antioquia y la secretaría de Salud del Amazonas, se capturaron 8 ejemplares adultos de A. albopictus en la ciudad de Leticia, departamento del Amazonas, siendo éste el primer hallazgo de esta especie en Colombia. La presencia en Colombia de A. albopictus vuelve más complejo el problema del dengue por la mayor adaptación de este vector a climas más fríos, la capacidad de transmisión transovariana, la buena capacidad vectorial para transmitir los cuatro serotipos del virus y la mayor dificultad para su control dado que sus criaderos están en áreas peridomésticas y rurales. La distribución de esta especie tanto en zonas selváticas como rurales y urbanas presenta un peligro potencial de urbanizar la transmisión de la fiebre amarilla. Se presenta el plan de contingencia que se debe implementar por parte de la Secretaría de Salud del Amazonas con miras a evitar la propagación de este vector a otras regiones del país.

    Full Text Available A violência de gênero contra as mulheres é um fenômeno mundial abordado exaustivamente. Este artigo discute como a interseccionalidade gênero, raça e etnia emerge nos discursos jurídicos sobre as mulheres que acessam a justiça. O referencial teórico foi composto pela analítica do poder de Michel Foucault articulada aos conceitos de interseccionalidade, gênero, raça e etnia. A pesquisa de campo foi realizada no Poder Judiciário de Porto Alegre e de Sevilha entre agosto de 2010 e outubro de 2012. Foram construídas três amostras de conveniência: entrevistas com 290 mulheres, análise de 70 processos judiciais e de 55 boletins de ocorrência. Foram realizadas entrevistas com quatro juízes/as de Porto Alegre e dois juízes em Sevilha. Os resultados apontam uma sobrerrepresentação das mulheres negras nos boletins de ocorrência, nas entrevistas, mas não nos processos. Apesar disso, os/as juízes/as entrevistados/as compreendem que a interseccionalidade gênero-raça e etnia não interfere no acesso à justiça.

Oaxaca destaca como uno de los estados donde las mujeres son más propensas a ser víctimas de una agresión. Este trabajo analiza la violencia de género en Ayutla, comunidad mixe de Oaxaca. Los datos fueron obtenidos a través de una estrategia metodológica mixta (cuantitativa- cualitativa. Entre los principales hallazgos están: la violencia psicológica es la más común; hay numerosos casos de incesto y estupro; la violencia económica generalmente asume la forma de abandono total de la pareja; las autoridades locales y del Estado ejercen violencia institucional al no atender las denuncias. Se analizan las estrategias discursivas de las mujeres para resignificar sus derechos dentro de su propia cultura, así como el éxito en la denuncia de un caso de violación dentro del matrimonio que fortaleció la defensa de tales derechos.

    Full Text Available OBJETIVO: Identificar práticas de cuidado à saúde e em situação de adoecimento adotadas por idosos de diferentes etnias. METODOS: O Interacionismo Simbólico e a Teoria Fundamentada nos Dados foram utilizados como estratégia teórico-metodológica. Dados coletados de fevereiro a julho de 2011 entre 33 idosos de cinco etnias diferentes, em seus domicílios. RESULTADOS: Os cuidados na saúde envolvem atividade física, alimentação, oração e trabalho, e somente os franceses demonstraram preocupação com isso ao longo da vida. Em situação de adoecimento, a fé e a religiosidade norteiam o cuidado entre os libaneses; a utilização de chás entre os paraguaios; a medicina tradicional associada ao uso de chás entre os franceses, chineses e brasileiros. CONCLUSÃO: As diferentes práticas de cuidado devem ser conhecidas pela enfermagem gerontológica, pois aproximam o profissional do idoso e sua família, permitindo-lhes planejar e implementar ações adequadas a cada situação específica.

    This paper analyses the health services regionalization process in the State of Amazonas through a case study covering the health sub-region Manaus Surroundings. This is a qualitative, descriptive and analytical research, which data were collected using interviews, documents and Internet reviews, oriented by the guiding concept of health regionalization. Study findings revealed a social setting dominated by asymmetry, verticality, competitiveness and fragile multilateral relations among municipalities, associated to a bureaucratic profile of local institutions operating in the region under study. The political agents have limited acknowledgement of the sociopolitical and institutional conditions in which they operate. They usually impute healthcare networks' management and operational issues to the natural and geographical characteristics of the Amazon region, but their financing, governance and technical capacity are insufficient to overcome them.

    Reducing tropical deforestation is a major climate and development issue: forest clearing is responsible for roughly a fifth of greenhouse gas emissions, and the forest-dependent poor number over a billion. In the runup to the Copenhagen climate summit, REDD – reducing emissions from deforestation and (forest) degradation by providing incentives to tropical forest countries – has been touted as one of the most cost-effective mitigation mechanisms on the table. But the benefits would be only temporary if forests saved today are cleared once incentives cease. Would the expense of maintaining such incentives over decades raise the price to uncompetitive levels? A forest reserve in Amazonas, Brazil, offers some of the first real-world data on the costs of REDD. Even with pessimistic assumptions about future pressures, the project's carbon cuts look highly affordable.

    Full Text Available OBJECTIVE: To assess potential risk factors associated with elevated blood lead levels (BLLs among children in two communities from the Corrientes River basin in the Peruvian Amazon. METHODS: Children aged 0-17 years were screened for BLLs, hemoglobin levels, and anthropometric measures. Dwelling, family, and child data were collected through a parental questionnaire. Statistical analysis included descriptive and bivariate analysis. Multiple linear and logistic regressions using generalized estimating equations were also conducted to determine associated risk factors. A map of each community was drawn to examine the spatial distribution of BLLs. RESULTS: Of 208 children (88 from 23 households of the Peruanito community and 120 from 28 households of Santa Isabel, 27.4% had BLLs > 10 µg/dL. The geometric mean (± standard deviation BLL was 8.7 ± 4.0 µg/dL (range 3.0-26.8 µg/dL. In the total population, linear regression analysis indicated that age was positively associated with BLLs (P 10 µg/dL than girls (P 10 µg/dL had 45.0% higher odds of presenting BLLs > 10 µg/dL than children whose mothers had BLLs 10 µg/dL were the main risk factors for elevated BLLs. The higher risk in boys 7-17 years suggests that exposure could be related to specific activities in this group, such as fishing and hunting. Continuous monitoring of BLLs in the Corrientes River population is recommended.OBJETIVO: Evaluar los potenciales factores de riesgo asociados con niveles elevados de plomo en sangre (Pbs en niños de dos comunidades de la cuenca del río Corrientes en la Amazonia peruana.

    Necropsies were conducted on a female blue-fronted Amazon (Amazona aestiva) and a female yellow-headed Amazon (Amazona oratrix) that died after depression, ruffled feathers, diarrhea, and biliverdin in the urine. Gross and microscopic examinations revealed multifocal necrosis in the liver, spleen, lungs, kidneys, intestines, and heart caused by acute bacteremia. Yersinia pseudotuberculosis, serogroup O:1a, was isolated by culturing from the visceral lesions in the liver, intestines, and spleen. Virulence gene analysis showed the presence of the inv gene and the complete pathogenicity island: IS100, psn, yptE, irp1, irp2 ybtP-ybtQ, ybtX-ybtS, and int asnT-Int. Histopathologic findings and chemical analysis also demonstrated hepatic hemosiderosis. As has been demonstrated in other species, hemosiderosis may predispose Amazona spp. to systemic infection with Y. pseudotuberculosis after enteric disease.

    Full Text Available INTRODUCTION: In the State of Amazonas, particularly in the capital Manaus, meningitis has affected populations of different cultures and social strata over the years. Bacterial meningitis is caused by several different species and represents a major issue of public health importance. The present study reports the meningitis case numbers with different etiologies in Amazonas from January 1976 to December 2012. METHODS: Since the 1970s, the (currently named Tropical Medicine Foundation of Doutor Heitor Vieira Dourado [Fundação de Medicina Tropical Doutor Heitor Vieira Dourado (FMT-HVD] has remained a reference center in Amazonas for the treatment of meningitis through the diagnosis and notification of cases and the confirmation of such cases using specific laboratory tests. RESULTS: The foundation has achieved coverage of over 90% of the state medical records for many years. Between 1990 and 2012, meningitis cases caused by Haemophilus influenzae decreased with the introduction of the H. influenzae vaccine. Meningococcal disease previously had a higher frequency of serogroup B disease, but starting in 2008, the detection of serogroup C increased gradually and has outpaced the detection of serogroup B. Recently, surveillance has improved the etiological definition of viral meningitis at FMT-HVD, with enteroviruses, Epstein-Barr virus (EBV and varicella zoster virus (VZV prevailing in this group of pathogens. With the advent of acquired immunodeficiency syndrome (AIDS, cryptococcal meningitis has become an important disease in Amazonas. Additionally, infectious meningitis is an important burden in the State of Amazonas. CONCLUSIONS: Changes in the epidemiological profile for the different etiology-defined cases are the result of continuous epidemiological surveillance and laboratory capacity improvements and control measures, such as Haemophilus influenzae vaccination.

    Full Text Available A recent and comprehensive review of the use of race and ethnicity in research that address health disparities in epidemiology and public health is provided. First it is described the theoretical basis upon which race and ethnicity differ drawing from previous work in anthropology, social science and public health. Second, it is presented a review of 280 articles published in high impacts factor journals in regards to public health and epidemiology from 2009-2011. An analytical grid enabled the examination of conceptual, theoretical and methodological questions related to the use of both concepts. The majority of articles reviewed were grounded in a theoretical framework and provided interpretations from various models. However, key problems identified include a a failure from researchers to differentiate between the concepts of race and ethnicity; b an inappropriate use of racial categories to ascribe ethnicity; c a lack of transparency in the methods used to assess both concepts; and d failure to address limits associated with the construction of racial or ethnic taxonomies and their use. In conclusion, future studies examining health disparities should clearly establish the distinction between race and ethnicity, develop theoretically driven research and address specific questions about the relationships between race, ethnicity and health. One argue that one way to think about ethnicity, race and health is to dichotomize research into two sets of questions about the relationship between human diversity and health.Se realizó revisión reciente y amplia de la utilización de raza y etnia en investigaciones dedicadas a las disparidades de salud en epidemiología y salud pública.

Brazil is one of 22 countries that accounts for 80% of the tuberculosis global burden. The highest incidence rates in Brazil occur in the States of Amazonas and Rio de Janeiro. The aim of this study was to describe the temporal distribution of TB in the State of Amazonas. Between 2001 and 2011, 28,198 cases of tuberculosis were reported in Amazonas, distributed among 62 municipalities, with the capital Manaus reporting the highest (68.7% concentration of cases. Tuberculosis was more prevalent among males (59.3% aged 15 to 34 years old (45.5%, whose race/color was predominantly pardo (64.7% and who had pulmonary TB (84.3%. During this period, 81 cases of multidrug-resistant TB were registered, of which the highest concentration was reported from 2008 onward (p = 0.002. The municipalities with the largest numbers of indigenous individuals affected were São Gabriel da Cachoeira (93%, Itamarati (78.1%, and Santa Isabel do Rio Negro (70.1%. The future outlook for this region includes strengthening the TB control at the primary care level, by expanding diagnostic capabilities, access to treatment, research projects developed in collaboration with the Dr. Heitor Vieira Dourado Tropical Medicine Foundation .;Fundação de Medicina Tropical Dr. Heitor Vieira Dourado (FMT-HVD.; and financing institutions, such as the project for the expansion of the Clinical Research Center and the creation of a hospital ward for individuals with transmissible respiratory diseases, including TB.

    A 4-year-old blue-fronted Amazon parrot (Amazona aestiva) was admitted for vocalization secondary to constipation. Saline infusion cloacoscopy revealed the presence of a 2-cm-diameter cloacolith within the coprodeum that was obstructing the rectal opening. The cloacolith was fragmented with a pair of biopsy forceps and the pieces removed. The cloacolith was subsequently analyzed and was composed of 100% uric acid salts. The bird improved completely and was able to defecate normally after the procedure. Cloacoliths are relative uncommon cloacal conditions, and this case documents cloacoscopic findings, rectal obstruction, and confirmation of its uric acid composition by urolith analysis.

    Osteoma is an uncommon bone formation documented in avian species and other animals. A blue-fronted Amazon parrot (Amazona aestiva) with clinical respiratory symptoms was examined because of a hard mass present on the left nostril. Radiographs suggested a bone tumor, and the mass was surgically excised. Histopathologic examination revealed features of an osteoma. To our knowledge, this is the first description of an osteoma in a blue-fronted Amazon parrot. Osteoma should be considered as a differential diagnosis in birds with respiratory distress and swelling of the nostril.

    2004-02-01

    Amazon parrots (Genus Amazona) are among the most recognizable and imperiled of all birds. Several hypotheses regarding the evolutionary history of Amazona are investigated using a combined phylogenetic analysis of DNA sequence data from six partitions including mitochondrial (COI, 12S, and 16S) and nuclear (beta-fibint7, RP40, and TROP) regions. The results demonstrate that Amazona is not monophyletic with respect to the placement of the Yellow-faced parrot (Amazona xanthops), as first implied by. In addition, the analysis corroborates previous studies suggesting a Neotropical short-tailed parrot genus as sister to Amazona. At a finer level, the phylogeny resolves the Greater Antillean endemic species as constituting a monophyletic group, including the Central American Amazona albifrons, while further revealing a paraphyletic history for the extant Amazon species of the Lesser Antilles. The reconstructed phylogeny provides further insights into the mainland sources of the Antillean Amazona, reveals areas of taxonomic uncertainty within the genus, and presents historical information that may be included in conservation priority-setting for Amazon parrots.

    Full Text Available Mundurukú, a Tupian language of Brazil, exhibits two opposite scenarios. On one extreme, there is Mundurukú do Pará, the language of daily communication in the Mundurukú Indigenous Land, with fluent speakers found across all generations and still acquired by children as a mother tongue. On the other extreme, there is Mundurukú do Amazonas, formerly spoken in the Kwatá-Laranjal Indigenous Land, but whose inhabitants have shifted to Portuguese. A group of Mundurukú students from Amazonas decided to initiate a process of language revitalisation as a way to strengthen the community's ethnic and cultural identity. This paper reports the initial stages of language planning, and includes future actions to promote language use in the homes and communities, assessement of language proficiency, and definition of educational programs to teach Mundurukú in local schools.Mundurukú, uma língua Tupí do Brasil, apresenta dois cenários opostos. Em um extremo, há o Mundurukú do Pará, a língua de comunicação diária na Terra Indígena Mundurukú, com falantes fluentes de todas as idades e adquirida pelas crianças como língua materna. No outro extremo encontra-se o Mundurukú do Amazonas, Terra Indígena Kwatá-Laranjal, que foi substituída pelo Português. Um grupo de estudantes Mundurukú do Amazonas decidiu iniciar um processo de revitalização de sua língua, como uma forma de fortalecer a identidade étnica e cultural da comunidade. Este trabalho relata os estágios iniciais do planejamento linguístico, incluindo as ações futuras para promover o uso da língua em casa e na comunidade, avaliação da proficiência na língua e definição de programas educacionais para ensinar Mundurukú nas escolas locais.

    Full Text Available Las amazonas son un símbolo femenino que aparece en obras artísticas y textos literarios, construyendo un imaginario de mujeres míticas y guerreras del que se han alimentado múltiples obras de cultura popular, casi siempre desde un punto de vista patriarcal y/o fálico. Sin embargo, es posible descubrir la existencia de algunos productos mainstream que subvierten esta representación, configurando un perfil heroico positivo y emancipador. El presente texto ofrece un análisis de dos obras recientes dirigidas a público juvenil: la película de animación Brave (Mark Andrews y Brenda Chapman, 2012 y la saga cinematográfica The Hunger Games (Gary Ross, 2012; Francis Lawrence, 2013, 2014 y 2015. En ambos casos existe un protagonismo femenino incuestionable que, desde un análisis feminista, ofrece una alternativa a la mayoría de personajes de la industria audiovisual, caracterizados por el sexismo y la subordinación a lo masculino pues, tanto Mérida como Katniss, son descritas como heroínas independientes, con personalidad y capacidad de decisión.

    A 37-year-old yellow-crowned Amazon parrot (Amazona ochrocephala) and a 20-year-old red-lored Amazon parrot (Amazona autumnalis) each presented with a large mass localized on the lateral neck. With the first bird, there was no evidence of signs of pain or discomfort, and the bird prehended and swallowed food normally. The second bird showed signs of mild upper-gastrointestinal discomfort. Results of an ultrasound examination and aspiration of the mass on each bird revealed a cystic structure. A computed tomography performed on the second bird revealed a large polycystic mass connected to the pharynx by a lateral tract. During surgical resection, both masses were found to originate from the subpharyngeal area. Based on topography and the histopathologic and immunohistochemical results, the masses were determined to be a second branchial cleft cyst for the first case and a second branchial pouch cyst for the second case. In addition, a carcinoma was present in situ within the epithelium of case 1, and the cyst in case 2 was secondarily infected. Branchial cysts are uncommonly diagnosed in veterinary and human medicine. These 2 cases are the first documented in parrots and appear similar to second branchial cysts reported in adult humans.

  16. [Nature and civilization: the decorative panels of the Teatro Amazonas foyer].

    The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between the landscape representations of Amazonian nature adorning the building's foyer, the construction of the modern city, and social uses of the Teatro Amazonas, symbol of the era and emblem of the newly rich elite, who were then taking their place on the regional and national stages. The Teatro Amazonas formed the center of the era's social life and its foyer played host to veritable rituals of 'civilization', in which Brazilian and foreign guests enjoyed the fine setting of Amazon's nature as represented in the decorative wall panels.

    The lipoprotein panel is a useful diagnostic tool that allows clinicians to evaluate blood lipoprotein fractions. It is a standard diagnostic test in human medicine but is poorly understood in avian medicine. Amazon parrots (Amazona species) are popular pets that frequently lead a sedentary lifestyle and are customarily fed high-fat diets. Similar to people with comparable diets and lifestyles, Amazon parrots are prone to obesity and atherosclerosis. In human medicine, these conditions are typically correlated with abnormalities in the lipoprotein panel. To establish reference intervals for the lipoprotein panel in Amazon parrots, plasma samples from 31 captive Amazon parrots were analyzed for concentrations of cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL). The data were also grouped according to sex, diet, body condition score, and age. Aside from HDL levels, which were significantly different between male and female parrots, no intergroup differences were found for any of the lipoprotein fractions.

    We radio-tagged and released 49 captive-reared Hispaniolan Parrots (Amazona ventralis) in Parque Nacional del Este (PNE), Dominican Republic, during 1997 and 1998. Our primary objective was to develop a restoration program centered on using aviary-reared birds to further the recovery of the critically endangered Puerto Rican Parrot (A. vittata). Hurricane Georges made landfall over the release area on 22 September 1998 with sustained winds of 224 km/h, providing us with a unique opportunity to quantify responses of parrots to such disturbances. Quantitative data on such responses by any avian species are scarce, particularly for Amazona species, many of which are in peril and occur in hurricane-prone areas throughout the Caribbean. Mean home ranges of 18 parrots monitored both before and after the hurricane increased (P = 0.08) from 864 ha (CI = 689-1039 ha) pre-hurricane to 1690 ha (CI = 1003-2377 ha) post-hurricane. The total area traversed by all parrots increased > 300%, from 4884 ha pre-hurricane to 15,490 ha post-hurricane. Before Hurricane Georges, parrot activity was concentrated in coastal scrub, tall broadleaf forest, and abandoned agriculture (conucos). After the hurricane, parrots concentrated their activities in areas of tall broadleaf forest and abandoned conucos. Topographic relief, primarily in the form of large sinkholes, resulted in "resource refugia" where parrots and other frugivores foraged after the hurricane. Habitat use and movement patterns exhibited by released birds highlight the importance of carefully considering effects of season, topography, and overall size of release areas when planning psittacine restorations in hurricane-prone areas. ??

    Full Text Available Las intoxicaciones alimentarias son ocasionadas por consumo de alimentos en malas condiciones de preparación o de conservación o que han sufrido contaminación con agentes quimicos, fisicos o biológicos. La reciente incorporación de la vigilancia de este evento en el sistema de vigilancia intensificado de la Secretaria de Salud del Amazonas, ha permitido identificar la presencia de brotes de intoxicación alimentaria en el departamento. En abril de 1997, se informó a la Oficina de Epidemiologia de la Secretaria de Salud del Amazonas, la llegada de 30 pacientes al Hospital Empresa Social del Estado San Rafael de Leticia, con un cuadro clinico de dolor abdominal, vómito y cefalea. Las pacientes eran estudiantes adolescentes del internado indígena femenino de Nazareth, que presentaban como antecedente común la ingestión de pescado recalentado el día anterior a su consulta. En la investigación del presente brote de intoxicación alimentaria se comprobó por laboratorio que el alimento implicado era la carne de caimán negro, Melanosuchusniger, contaminada con Bacillus cereus. Esta carne iba a ser vendida como 'pescado seco' en Bogotá, por la gran demanda que tiene este alimento en la época de Semana Santa.

    The intracratonic Amazonas Basin covers an area close to 500.000km{sup 2} shared between the Amazonas and Para states. The phanerozoic stratigraphic framework is up to 6.000m thick and may be subdivided into two, first order depositional sequences: the Paleozoic sequence, intruded by diabase dikes and sills and the Mesozoic-Cenozoic sequence. Analyzing the stratigraphic framework, the great tectonic influence on the basin development can be appreciated. The mainly NW-SE structural directions of the basement, which mark the boundaries of the geochronological provinces of the Amazonas, are clearly identified along the Tapajos River. The Paleozoic sequence outcrops on the southern border of the Amazonas Basin embraces potential source rocks, reservoirs and seal rocks. They can be subdivided in three, second order sequences, limited by regional unconformities, as: the Ordovician/Devonian, which corresponds to the Pitinga lithostratigraphic formation; the Devonian-Tournaisian, which corresponds to the Maecuru, Erere, Barreirinha and Curiri formations and, the Pensylvanian-Permian that are represented by the Monte Alegre and Itaituba formations. This field trip guide presents these classic lithostratigraphic outcrop units, together with a brief sedimentological description and an analysis of their positioning related to sequence stratigraphical concepts.

    Despite the availability of tuberculosis prevention and control services throughout Amazonas, high rates of morbidity and mortality from tuberculosis remain in the region. Knowledge of the social determinants of tuberculosis in Amazonas is important for the establishment of public policies and the planning of effective preventive and control measures for the disease. To analyze the relationship of the spatial distribution of the incidence of tuberculosis in municipalities and regions of Amazonas to the socioeconomic factors and indigenous tuberculosis component, from 2007 to 2013. An ecological study was conducted based on secondary data from the epidemiological surveillance of tuberculosis. A linear regression model was used to analyze the relationship of the annual incidence of tuberculosis to the socioeconomic factors, performance indicators of health services, and indigenous tuberculosis component. The distribution of the incidence of tuberculosis in the municipalities of Amazonas was positively associated with the Gini index and the population attributable fraction of tuberculosis in the indigenous peoples, but negatively associated with the proportion of the poor and the unemployment rate. The spatial distribution of tuberculosis in the different regions of Amazonas was heterogeneous and closely related with the socioeconomic factors and indigenous component of tuberculosis.

    Naturally occurring radionuclides, such as the uranium and thorium decay chains, are present in rocks and soils. But its distribution is not homogeneous: it depends on the type of rock being that those of volcanic origin have higher concentrations of uranium and thorium. These are NORM. Locations with NORM present higher dose rates than the world average. Thus, the determination of the natural radioactivity of a NORM region is of extreme importance since it provides data for the estimation of human exposure to natural radiation. In addition, if there is a mining company exploring NORM, the background radiation estimation should be considered in the decommissioning and future planning. There are places in Brazil, such as Granito Madeira in the state of Amazonas, in the north of Brazil, where NORM is present. It is an extremely remote area located within the Amazon Forest currently in the process of open cast mining. In this study, the iodide scintillator detector was used to measure and map the natural background radiation of the Granito Madeira using a scintillator detector of sodium iodide that was transported in tracks within the forest. The data obtained were georeferenced, classified and used to obtain the annual dose related to gamma radiation. The results are presented in frequency histograms and maps. The annual average was (6.0 ± 3.0) mSv.y{sup -1}. These data were compared to those available from other regions with NORM in Brazil and the 2010 UNSCEAR report. (author)

    The objective of this study was to evaluate the protein requirements for hand-rearing Blue-fronted Amazon parrots (Amazona aestiva). Forty hatchlings were fed semi-purified diets containing one of four (as-fed basis) protein levels: 13%, 18%, 23% and 28%. The experiment was carried out in a randomized block design with the initial weight of the nestling as the blocking factor and 10 parrots per protein level. Regression analysis was used to determine relationships between protein level and biometric measurements. The data indicated that 13% crude protein supported nestling growth with 18% being the minimum tested level required for maximum development. The optimal protein concentration for maximum weight gain was 24.4% (p = 0.08; r(2) = 0.25), tail length 23.7% (p = 0.09; r(2) = 0.19), wing length 23.0% (p = 0.07; r(2) = 0.17), tarsus length 21.3% (p = 0.06; r(2) = 0.10) and tarsus width 21.4% (p = 0.07; r(2) = 0.09). Tarsus measurements were larger in males (p < 0.05), indicating that sex must be considered when studying developing psittacines. These results were obtained using a highly digestible protein and a diet with moderate metabolizable energy levels.

  6. Uranium isotopes in groundwater occurring at Amazonas State, Brazil

    2015-01-01

    This paper reports the behavior of the dissolved U-isotopes 238 U and 234 U in groundwater providing from 15 cities in Amazonas State, Brazil. The isotope dilution technique accompanied by alpha spectrometry were utilized for acquiring the U content and 234 U/ 238 U activity ratio (AR) data, 0.01–1.4 µg L −1 and 1.0–3.5, respectively. These results suggest that the water is circulating in a reducing environment and leaching strata containing minerals with low uranium concentration. A tendency to increasing ARs values following the groundwater flow direction is identified in Manaus city. The AR also increases according to the SW–NE directions: Uarini→Tefé; Manacapuru→Manaus; Presidente Figueiredo→São Sebastião do Uatumã; and Boa Vista do Ramos→Parintins. Such trends are possibly related to several factors, among them the increasing acid character of the waters. The waters analyzed are used for human consumption and the highest dissolved U content is much lower than the maximum established by the World Health Organization. Therefore, in view of this radiological parameter they can be used for drinking purposes. - Highlights: • U-isotopes data in important aquifer systems in Amazon area. • Application of the U-isotopes data to investigate the groundwater flow direction. • Evaluation of the drinking-water quality in terms of dissolved uranium

    A clinically normal 2-year-old Hispaniolan Amazon parrot (Amazona ventralis) was found to have periodic second-degree atrioventricular (AV) block with variable nodal conductions while anesthetized with isoflurane during a thermal-support research project. Arrhythmias were observed on 5 successive weekly electrocardiograms. A complete cardiac evaluation, including a diagnostic electrocardiogram, revealed intermittent bradyarrhythmias ranging from a 2:1 to a 7:1 second-degree AV block, with concurrent hypotensive episodes during the nodal blocks. Results of a complete blood cell count, plasma biochemical profile, blood gas analysis, and atropine-response test, as well as radiography and auscultation, revealed no obvious cause for the arrhythmias. Echocardiography demonstrated cardiac wall thickness, chamber size, and systolic function similar to other psittacine birds. On return to the colony, the parrot continued to be outwardly asymptomatic despite the dramatic conduction disturbances. Although cardiac arrhythmias, including second-degree AV block, have been widely reported in birds, the wide variation of nodal conductions, the intermittent nature, and an arrhythmia with a 7:1 second-degree AV block that spontaneously reverts to normal as seen in this case have not been well documented in parrots.

  8. Multifragment alleles in DNA fingerprints of the parrot, Amazona ventralis

    Human DNA probes that identify variable numbers of tandem repeat loci are being used to generate DNA fingerprints in many animal and plant species. In most species the majority of the sc rable autoradiographic bands of the DNA fingerprint represent alleles from numerous unlinked loci. This study was initiated to use DNA fingerprints to determine the amount of band-sharing among captive Hispaniolan parrots (Amazona ventralis) with known genetic relationships. This would form the data base to examine DNA fingerprints of the closely related and endangered Puerto Rican parrot (A. vittata) and to estimate the degree of inbreeding in the relic population. We found by segregation analysis of the bands scored in the DNA fingerprints of the Hispaniolan parrots that there may be as few as two to five loci identified by the human 33.15 probe. Furthermore, at one locus we identified seven alleles, one of which is represented by as many as 19 cosegregating bands. It is unknown how common multiband alleles might be in natural populations, and their existence will cause problems in the assessment of relatedness by band-sharing analysis. We believe, therefore, that a pedigree analysis should be included in all DNA fingerprinting studies, where possible, in order to estimate the number of loci identified by a minisatellite DNA probe and to examine the nature of their alleles.

    Retrobulbar neoplasms are not common in mammals and are even more infrequently seen in nonmammalian species. The current report describes a retrobulbar mass creating exophthalmia and neurologic signs in a red-lored Amazon parrot (Amazona autumnalis). A 27-year-old female parrot presented for a 3-day history of anorexia and a 2-week history of periocular soft tissue swelling and exophthalmia of the right eye. Physical examination revealed 9% dehydration and right eye exophthalmia with inability to retropulse the globe. A fine-needle aspirate was performed, and cytologic evaluation revealed necrotic debris with scattered clusters of epithelial cells, moderate numbers of macrophages, and few heterophils. Given the possibility of neoplasia and paucity of treatment options, the owners elected euthanasia and submitted the body for necropsy. A large, fluctuant, friable, red, retrobulbar mass with multiple areas of hemorrhage, on cut surface, was noted at necropsy. Histologically, the mass was composed of neoplastic, cuboidal to columnar epithelial cells, forming rosette-like glandular structures, admixed with abundant necrotic debris. The neoplastic cells were strongly positive for cytokeratin (AE1/AE3) by immunohistochemistry. Based on histopathology and immunohistochemistry, the mass was diagnosed as an adenocarcinoma.

    Amazona barbadensis is an endangered species of parrot living in northern coastal Venezuela and in several Caribbean islands. In this study, we sequenced full mitochondrial genome of the considered species. The total length of the mitogenome was 18,983 bp and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, duplicated control region, and degenerate copies of ND6 and tRNA (Glu) genes. High degree of identity between two copies of control region suggests their coincident evolution and functionality. Comparative analysis of both the control region sequences from four Amazona species revealed their 89.1% identity over a region of 1300 bp and indicates the presence of distinctive parts of two control region copies.

    Full Text Available ABSTRACT The fauna of blowflies (Calliphoridae and Mesembrinellidae in three localities of primary Amazon forest coverage in the Amazonas-Negro interfluvial region was assessed. A total of 5066 blowflies were collected, with Chloroprocta idiodea being the most abundant species (66.3%. A difference in species richness between the localities ZF2 and Novo Airão was observed. Comparison among sampled sites revealed no considerable variation in fauna composition, except for the species Eumesembrinella benoisti (Séguy 1925 and Hemilucilia sp., whose occurrence was observed only in a single locality. Apparently, Amazon rivers are not efficient geographical barriers to influence the current composition of necrophagous blowfly assemblages. Also, most of the blowfly species did not show a noticeable specificity for any specific forest among the interfluvial areas of the ombrophilous forest. Finally, an updated checklist of necrophagous blowfly species of the Amazonas state in Brazil is presented.

    In the State of Amazonas, Brazil, urban expansion together with precarious basic sanitation conditions and human settlement on river banks has contributed to the persistence of waterborne and intestinal parasitic diseases. Time series of the recorded cases of cholera, typhoid fever, hepatitis A and leptospirosis are described, using data from different levels of the surveillance systems. The sources for intestinal parasitosis prevalence data (non-compulsory reporting in Brazil) were Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana (LILACS) and the annals of major scientific meetings. Relevant papers and abstracts in all languages were accessed by two independent reviewers. The references cited by each relevant paper were scrutinized to locate additional papers. Despite its initial dissemination across the entire State of Amazonas, cholera was controlled in 1998. The magnitude of typhoid fever has decreased; however, a pattern characterized by eventual outbreaks still remains. Leptospirosis is an increasing cause of concern in association with the annual floods. The overall prevalence of intestinal parasites is high regardless of the municipality and the characteristics of areas and populations. The incidence of hepatitis A has decreased over the past decade. A comparison of older and recent surveys shows that the prevalence of intestinal parasitic diseases has remained constant. The load of waterborne and intestinal parasitic diseases ranks high among the health problems present in the State of Amazonas. Interventions aiming at basic sanitation and vaccination for hepatitis A were formulated and implemented, but assessment of their effectiveness in the targeted populations is still needed.

    Full Text Available La globalización económica ha acentuado la desigualdad y la vulnerabilidad a las enfermedades tropicales en todo el mundo. La población del Amazonas venezolano y particularmente la población indígena del interior del Estado es uno de los segmentos más desfavorecidos de las Américas a juzgar por los indicadores de salud. Las tasas de mortalidad infantil observadas en poblaciones indígenas en áreas remotas indican que han sido afectadas por la globalización de las enfermedades, pero no se han beneficiado de la globalización de la salud. Por otra parte, la globalización ha influido en las políticas públicas lo cual afectó la eficiencia de los programas de control de enfermedades tropicales en Amazonas. Un nuevo pacto mundial para el desarrollo sostenible de la aldea global es necesario, a través de la "globalización" de los valores y los derechos comunes de la humanidad. En Venezuela, nuevas políticas dirigidas hacia el subsector de salud indígena, más recursos y mayor autonomía de acción pueden ayudar a reducir las inequidades aquí descritas en el Amazonas venezolano.Economic globalization appears to be causing greater inequalities and increased vulnerability to tropical diseases around the world. The Venezuelan Amazon population, especially the rural indigenous population, displays among the worst health indicators in the Americas. High infant mortality rates in remote indigenous populations indicate that such communities have been affected by the globalization of disease, rather than favored by globalization of health. Globalization has also influenced public policies in the country, affecting the efficiency of control programs targeting tropical diseases. A new global pact for the sustainable development of the planet is needed, supported by the globalization of human values and rights. In Venezuela, new policies for the indigenous health sector, more resources, and greater autonomy could help reduce the inequities

    Full Text Available Os painéis decorativos do salão nobre do Teatro Amazonas singularizam-se em relação ao restante da iconografia que decora o edifício, inaugurado em 1896. Na ocasião, as capitais do Pará e do Amazonas, enriquecidas pela economia gomífera, passaram por significativas transformações no tecido urbano e nas formas de sociabilidade, projetando-se nacional e internacionalmente. O artigo procura identificar paralelos entre as representações paisagísticas da natureza amazônica que decoram o salão nobre do edifício, a construção da cidade moderna e os usos sociais do Teatro Amazonas, símbolo do período e emblema da elite enriquecida que se afirmava no cenário regional e nacional. O Teatro Amazonas ocupou o centro da vida social da época, e em seu salão nobre ocorreram verdadeiros rituais de 'civilização' em que os convidados - brasileiros ou estrangeiros - tinham como cenário privilegiado a natureza amazônica representada nos painéis parietais decorativos.The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between the landscape representations of Amazonian nature adorning the building's foyer, the construction of the modern city, and social uses of the Teatro Amazonas, symbol of the era and emblem of the newly rich elite, who were then taking their place on the regional and national stages. The Teatro Amazonas formed the center of the era's social life and its foyer played host to veritable rituals of 'civilization', in which Brazilian and foreign guests enjoyed the fine setting of Amazon's nature as represented in the decorative wall panels.

    Full Text Available A falta de protocolos de sedação seguros para uso em papagaios na literatura demonstra a necessidade de conhecer os anestésicos que são eficazes nestes animais. Devido a pouca massa muscular desta espécie, notou-se a necessidade de estudar outra via de administração, menos invasiva e dolorosa ao animal, como a via intranasal. O objetivo deste estudo foi avaliar os efeitos sedativos e a viabilidade da administração intranasal, em comparação à via intramuscular, de 15mg/kg de Cetamina e 1mg/kg de Midazolam. Foram utilizados 14 papagaios das espécies Amazona aestiva e Amazona vinacea, de ambos os sexos, adultos, peso médio de 388,5±29,1g. Os animais foram distribuídos aleatoriamente em dois grupos: intramuscular (IM, n=7 e intranasal (IN, n=7. No grupo intramuscular, a administração dos anestésicos foi realizada nos músculos peitorais, utilizando seringas de insulina e no grupo intranasal, com auxílio de uma micropipeta. Avaliou-se o período de latência, tempo de duração, qualidade de sedação, e o tempo de recuperação total. A média para o período de latência no grupo IM foi de 6,13±2,02 minutos e no grupo IN de 4,84±2,37 minutos. Já para o tempo de duração da sedação no grupo IM a média foi de 35,81±29,56 e no grupo IN de 24,52±14,83 minutos. Ambas as vias promoveram sedação adequada, pois a média do escore da qualidade de sedação obtida pelo grupo IM foi 2±1,5 e pelo grupo IN 1,28±1,1. O tempo de recuperação total no grupo IM foi de 27,04±11,69 e no grupo IN de 17,67±11,64 minutos. Apesar do grupo IN ter apresentado os menores tempos de período de latência, duração e de recuperação total e ter obtido melhor escore na qualidade de sedação, não houve diferença estatística significativa entre os grupos. Os resultados obtidos neste estudo indicam que a administração de 15 mg/kg de cetamina e 1mg/kg de midazolam pela via intranasal ou intramuscular em papagaios (Amazona aestiva e

    Safe and effective sedation protocols are important for chemical restraint of birds in clinical and diagnostic procedures, such as clinical evaluations, radiographic positioning, and blood collection. These protocols may reduce stress and ease the management of wild-caught birds, which are susceptible to injury or death when exposed to stressful situations. We compare the sedative effect of intranasal midazolam in wild-caught blue-fronted (Amazona aestiva) and orange-winged (Amazona amazonica) Amazon parrots. Ten adult parrots of each species (n = 20), of unknown sex, weighing 0.337 ± 0.04 (blue-fronted) and 0.390 ± 0.03 kg (orange-winged), kg were used. Midazolam (2 mg/kg) was administered intranasally and the total volume of the drug was divided equally between the 2 nostrils. Onset time and total sedation time were assessed. Satisfactory sedation for clinical evaluation was induced in all birds. Onset time and total sedation times were similar in both species: 5.36 ± 1.16 and 25.40 ± 5.72 minutes, respectively, for blue-fronted Amazons and 5.09 ± 0.89 and 27.10 ± 3.73 minutes, respectively, for orange-winged Amazons. A total of 15 animals showed absence of vocalization, with moderate muscle relaxation and wing movement upon handling, and 2 animals presented with lateral recumbence, with intense muscle relaxation and no wing movement, requiring no restraint. Three blue-fronted Amazons had no effective sedation. Intranasally administered midazolam at a dose of 2 mg/kg effectively promoted sedative effects with a short latency time and fast recovery in wild-caught parrots.

    Full Text Available In the State of Amazonas, Brazil, urban expansion together with precarious basic sanitation conditions and human settlement on river banks has contributed to the persistence of waterborne and intestinal parasitic diseases. Time series of the recorded cases of cholera, typhoid fever, hepatitis A and leptospirosis are described, using data from different levels of the surveillance systems. The sources for intestinal parasitosis prevalence data (non-compulsory reporting in Brazil were Medical Literature Analysis and Retrieval System Online (MEDLINE, Literatura Latino-Americana (LILACS and the annals of major scientific meetings. Relevant papers and abstracts in all languages were accessed by two independent reviewers. The references cited by each relevant paper were scrutinized to locate additional papers. Despite its initial dissemination across the entire State of Amazonas, cholera was controlled in 1998. The magnitude of typhoid fever has decreased; however, a pattern characterized by eventual outbreaks still remains. Leptospirosis is an increasing cause of concern in association with the annual floods. The overall prevalence of intestinal parasites is high regardless of the municipality and the characteristics of areas and populations. The incidence of hepatitis A has decreased over the past decade. A comparison of older and recent surveys shows that the prevalence of intestinal parasitic diseases has remained constant. The load of waterborne and intestinal parasitic diseases ranks high among the health problems present in the State of Amazonas. Interventions aiming at basic sanitation and vaccination for hepatitis A were formulated and implemented, but assessment of their effectiveness in the targeted populations is still needed.

  3. A historical overview of leprosy epidemiology and control activities in Amazonas, Brazil

    Full Text Available Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC, which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

    A 9-year-old male Yellow-headed Amazon (Amazona oratrix) with a history of anorexia and vomiting died of a liver tumor. The tumor consisted of neoplastic cells with hepatocellular and cholangiocellular differentiations and their intermingled areas. Neoplastic hepatocytes showed islands or trabecular growth with vacuolated eosinophilic cytoplasm. Cells showing biliary differentiation formed ducts or tubules lined by cytokeratin AE1/AE3-positive epithelia, accompanied by desmoplasia consisting of myofibroblasts reacting to α-smooth muscle actin and desmin. The tumor was diagnosed as a combined hepatocellular-cholangiocarcinoma, which is very rare in the avian.

    The Puerto Rican parrot ( Amazona vittata ) has become an iconic and high-profile conservation species. The cornerstone of the recovery plan for this critically endangered species is an active captive breeding program, management of the wild population, and a long-term reintroduction program. In 2002, 40 adult Puerto Rican parrots that had not produced viable offspring were selected for reproductive assessment at 2 aviary populations in Puerto Rico (Iguaca and Río Abajo), which are the only sources of parrots for release. The goal was to enhance reproductive potential and produce productive pairings in an attempt to augment the population growth and provide ample individuals for reintroduction. Seven Hispanolian Amazon parrots ( Amazona ventralis ) that were used as surrogate parents for the Puerto Rican parrots were also included in the study. This assessment included physical examination, endoscopic evaluation, hematologic and plasma biochemical profiles, viral screening, and hormonal assays. Results of general physical examination and hematologic and plasma biochemical testing revealed overall good health and condition of this subset of the population of Puerto Rican parrots; no major infectious diseases were found. Endoscopic examination also revealed overall good health and condition, especially of females. The apparent low fertility of male birds warrants further investigation. The findings helped to define causes of reproductive failure in the selected pairs and individual birds. New pairings resulting from the assessment helped to augment reproduction of this critically endangered species.

    Full Text Available Este estudo objetivou analisar a percepção que as Organizações da Sociedade Civil fazem de sua contribuição na história do enfrentamento à AIDS, no Amazonas. Trata-se de pesquisa qualitativa com uso de fontes documentais e orais. Os dados foram coletados entre junho e setembro de 2013. Utilizou-se técnica de entrevistas com roteiro semiestruturado com as lideranças de oito organizações que trabalham/trabalharam com grupos mais vulneráveis. A partir da análise do discurso, concluiu-se que com a descentralização de recursos do Departamento de DST, AIDS e Hepatites Virais para as Coordenações locais, as Organizações reconhecem dois momentos distintos: um primeiro momento de fortalecimento organizacional, engajamento coletivo e participação política ativa; e um momento atual de distanciamento entre as Organizações e desarticulação política e, consequentemente, enfraquecimento do movimento social na luta contra AIDS no Amazonas.

    The Brazilian Paleozoic ichthyofauna from the Parnaíba and Amazonas basins regard a sparsely known diversity, including chondrichthyans and acanthodians, besides some osteichthyan remains. This work proposes a revision of the fossil material from these two sedimentary basins and synthesizes the morphological aspect of such material trying to understand the influences of those fossils to the paleontology of the region, comparing the Brazilian fossils with other gondwanan faunas. The Brazilian Paleozoic fish fauna shows great resemblance to those of Bolivia, especially during the Devonian. Many of the Acanthodian spines from the Manacapuru Formation (Amazonas Basin), and the Pimenteira Formation (Parnaíba Basin), are comparable to the taxa found in Bolivia. The lack of more Placoderm remains in the Brazilian outcrops is similar to the low diversity of this group in Bolivia, when compared to other South American and Euramerican localities. The most diverse Brazilian ichthyofauna is encountered in the Permian Pedra de Fogo Formation where numerous chondrichthyans and 'paleopterygians' remains are found, together with dipnoans and actinistians. Despite the apparent lack of more representative Paleozoic ichthyofaunas in Brazil, the available material that ranges from Lower Devonian to early Permian from Brazil bears important taxa that could address valuable taxonomic and biogeographic informations.

Objetivo: Identificar el estado nutricional y aspectos alimentarios en mujeres indígenas de tres comunidades del Departamento de Presidente Hayes, Chaco Paraguayo. Metodología: Estudio observacional de diseño transversal con componente analítico, que incluyó a 81 mujeres de 15 a 44 años de edad, de las etnias Maká y Toba Qom. Previo consentimiento informado, se realizó la valoración nutricional y la entrevista para obtener los datos sociodemográficos y alimentarios. Resultados: Las mujeres indígenas presentaron una frecuencia de sobrepeso de 30,8% y obesidad del 21,0%, mientras que el 1,2 % presentó desnutrición. No encontramos diferencia significativa entre las etnias, en relación al sobrepeso y obesidad, (p>0,05. Observamos que las indígenas tenían una alta ingesta de frutas, azúcares y mieles. El 87 y 88% de las mujeres indígenas de ambas etnias estudiadas refirieron no consumir lácteos y derivados y entre 65 y 69% refirieron no consumir verduras. Conclusiones: Observamos un elevado porcentaje de obesidad y sobrepeso, un bajo consumo de lácteos y verduras y un alto consumo de azúcares, relacionados posiblemente a cambios en los aspectos alimentarios y sus costumbres, influenciados por la cercanía a las zonas urbanas y el acceso a alimentos de menor precio y mayor contenido energético.

Este tema ha sido objeto de varias investigaciones e instancias académicas y científicas, siempre con el objetivo de lograr que la lectura sea accesible a todos. Brasil es conocido por su enorme extensión, pero carece de eficiencia en la ejecución de dichos proyectos. El Estado de Amazonas ocupa la superficie terrestre más grande del país; además, el transporte fluvial por los ríos es la única forma de acceso a las comunidades. El artículo describe un conjunto de actividades con el fin de acercar la lectura a las comunidades ribereñas, en un intento de democratizar el acceso a los libros y la lectura en ausencia de las bibliotecas públicas contribuyendo, de este modo, al proceso de inclusión informacional en la sociedad actual de la información y del conocimiento, donde la cuestión de la lectura es un desafío y, aunque sea una condición esencial, todavía existen analfabetos que necesitan ser incluidos con el fin de garantizar su participación como ciudadanos = Reading is a key factor for life in society, yet there are people who have not appropriated this habit.

    The scope of this paper was to analyze the perception of community-based organizations and their contributions to the history of tackling Aids in Amazonas State. It involved qualitative research with the use of oral and documental sources. Data were collected between June and September 2013 by means of semi-structured interviews with the leaders of eight organizations that work or worked with more vulnerable communities. Based on Discourse Analysis the conclusion drawn is that that the organizations perceive two distinct phases since the decentralization of funds from the Sexually-Transmitted Diseases Aids and Viral Hepatitis Department to the local leaders. The first phase was marked by the strengthening of organizations, collective empowerment and active political participation. The current phase has seen the distancing between organizations, a loss of political momentum and weakening of common response and organization.

    Full Text Available Hepatitis B Virus (HBV infection is a worldwide public health problem. In the 1980's a highly effective and safe vaccine against HBV was developed, although breakthrough infection still occasionally occurs because of the emergence of escape mutants. The aim of this study was to identify HBV genotypes and escape mutants in children and their mothers in Amerindian communities of the Amazonas State, Southern Colombia.Blood specimens collected from children and mothers belonging to 37 Amerindian communities in Amazonas state, were screened for HBsAg and anti-HBc using ELISA. The partial region containing the S ORF was amplified by nested PCR, and amplicons were sequenced. The phylogenetic analysis was performed using the MEGA 5.05 software.Forty-six children (46/1275, 3.6% and one hundred and seventy-seven mothers (177/572, 30.9% were tested positive for the anti-HBc serological marker. Among them, 190 samples were tested for viral genome detection; 8.3% (2/31 serum samples obtained from children and 3.1% (5/159 from mothers were positive for the ORF S PCR. The predominant HBV genotype in the study population was F, subgenotype F1b; in addition, subgenotype F1a and genotype A were also characterized. Two HBV escape mutants were identified, G145R, reported worldwide, and W156*; this stop codon was identified in a child with occult HBV infection. Other mutations were found, L109R and G130E, located in critical positions of the HBsAg sequence.This study aimed to characterize the HBV genotype F, subgenotypes F1b and F1a, and genotype A in Amerindian communities and for the first time escape mutants in Colombia. Further investigations are necessary to elucidate the frequency and the epidemiological impact of the escape mutants in the country.

    Full Text Available This study evaluated the occurrence of American tegumentary leishmaniasis (ATL in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010. The disease was predominantly observed in males (76.2%, in the 21- to 30-year-old age group (26.6% and in extractive workers (43.7%; 3.3% of the cases were the mucosal form. The endemic channel shows the disease seasonality, with a predominance of cases at the beginning and end of each year. The number of cases by municipality in the period of 2001-2010 shows the maintenance of the endemic in the localities where the highest numbers of cases have always been registered, namely, Manaus, Rio Preto da Eva, Itacoatiara and Presidente Figueiredo. The comparison of data from 2001 to 2005 and from 2006 to 2010 showed the emergence of this disease in municipalities that had been previously unaffected. In the last years, there has been a significant increase in the activities of control, diagnosis and treatment of leishmaniasis in the State of Amazonas. In conclusion, the historical series of ATL analyzed in this study suggests that the transmission foci remain and are even expanding, though without continuous transmission in the intra- or peridomicile settings. Moreover, the disease will persist in the Amazon while the factors associated with infection acquisition relative to forest exploitation continue to have economic appeal. There is a real expectation of wide variations in disease incidence that can be influenced by climate and economic aspects.

    Full Text Available Dengue is a vector-borne disease in the tropical and subtropical region of the world and is transmitted by the mosquito Aedes aegypti. In the state of Amazonas, Brazil during the 2011 outbreak of dengue all the four Dengue virus (DENV serotypes circulating simultaneously were observed. The aim of the study was to describe the clinical epidemiology of dengue in Manaus, the capital city of the state of the Amazonas, where all the four DENV serotypes were co-circulating simultaneously.Patients with acute febrile illness during the 2011 outbreak of dengue, enrolled at the Fundação de Medicina Tropical Dr. Heitor Viera Dourado (FMT-HVD, a referral centre for tropical and infectious diseases in Manaus, were invited to participate in a clinical and virological descriptive study. Sera from 677 patients were analyzed by RT-nested-PCRs for flaviviruses (DENV 1-4, Saint Louis encephalitis virus-SLEV, Bussuquara virus-BSQV and Ilheus virus-ILHV, alphavirus (Mayaro virus-MAYV and orthobunyavirus (Oropouche virus-OROV.Only dengue viruses were detected in 260 patients (38.4%. Thirteen patients were co-infected with more than one DENV serotype and six (46.1% of them had a more severe clinical presentation of the disease. Nucleotide sequencing showed that DENV-1 belonged to genotype V, DENV-2 to the Asian/American genotype, DENV-3 to genotype III and DENV-4 to genotype II.Co-infection with more than one DENV serotype was observed. This finding should be warning signs to health authorities in situations of the large dispersal of serotypes that are occurring in the world.

    Being a form of cheap energy, abundant and accessible, the vegetable coal is quite often used generally in the urban and rural areas in the Amazonas state, domestic and commercial use as well. Several families live of the production activity and commercialization of vegetable coal inside the State of Amazonas. However, actions of government organs of the environment area turn more and more difficult the exercise of those activities, creating a situation of clandestine production and in some cases making unfeasible the only form of subsistence of several families. Besides the legal aspect there exist the low technological level, being the production of vegetable coal done in ovens of the type 'hot tail', which cause problems for the users health. The mentioned subjects are discussed in that work based on the study accomplished at three places producing the vegetable coal in the the State of Amazonas hinter side, in the proximities of Manaus. Through the information obtained in the communities a proposal is presented for the small scale production of vegetable coal in a economical, social and environmentally self sustainable way.

    Full Text Available The main objective of the present text is to analyze environmental governance in the Sustainable Development Reserve Igapó-Açu, located in the municipalities of Manicoré, Borba and Beruri, state of Amazonas, Brazil. The study area was chosen because the RDS is the only Amazonas state protected area crossed by a federal interstate highway. This highway provides a specific territorial arrangement of governance elements in the studied area. Different methodological tools were used in this research, such as close-ended questionnaires and open-ended interviews. Data were systematized using Excel software and they were graphically represented in the form of organizational charts drawn with Websphere Analysis Software. Results indicate that environmental governance of the RDS Igapó-Açu involves multiple factors, while the central node of the local political articulation is held by a Management Council that is in charge of materializing the governability of the RDSt, as well as its ramifications.

    Full Text Available We investigated the use of Bacillus thuringiensis isolated in the state of Amazonas, in Brazil, for the biological control of the dengue vector Aedes aegypti. From 25 soil samples collected in nine municipalities, 484 bacterial colonies were obtained, 57 (11.78% of which were identified as B. thuringiensis. Six isolates, IBt-03, IBt-06, IBt-07, IBt-28, IBt-30, and BtAM-27 showed insecticidal activity, and only BtAM-27 presents the five genes investigated cry4Aa, cry4Ba, cry10Aa, cry11Aa, and cry11Ba. The IBt-07 and IBt- 28, with lower LC50 values, showed equal toxicity compared to the standards. The isolates of B. thuringiensis from Amazonas constitute potential new means of biological control for A. aegypti, because of their larvicidal activity and the possibility that they may also contain new combinations of toxins.

    2003-01-01

    Full Text Available En seres humanos, la varianza en éxito reproductivo es mayor en hombres que en mujeres. Dada esta caracterísitca, Trivers y Willard postularon que sería ventajoso para madres en buenas condiciones físicas invertir en engendrar varones, mientras que aquellas madres cuyo estado físico no es óptimo deberían engendrar niñas. Una disminución en el estado nutricional y físico de la madre, un aumento de la edad materna al nacimiento y un incremento en el orden de paridad, determinaría una disminución en la proporción de hijos varones al momento del nacimiento. El objetivo de este trabajo es el de evaluar la hipótesis de Trivers y Willard en dos comunidades Toba de la provincia de Formosa. Se relevaron 396 historias reproductivas de mujeres de una comunidad peri-urbana y 336 de una comunidad rural. Se estimó el Indice de Masculinidad (IM de cada comunidad desde el año 1980 y se analizó su variación en relación a la edad materna y la paridad. Ambas comunidades muestran una disminución del IM a partir primer nacimiento. La comunidad peri-urbana muestra una caída del IM en relación con la edad materna hasta los 39 años incrementándose a partir de los 40 años. La comunidad rural, muestra un patrón similar, pero con un primer aumento entre los 25 y 29 años. Los resultados muestran una importante caída del IM hasta los años 1985-1988 y una recuperación a partir de esos años. La asociación con variables socioeconómicas durante estos años también se presentará como posible evidencia a favor de la hipótesis bajo estudio.

    Full Text Available Envenoming snakebites are thought to be a particularly important threat to public health worldwide, especially in rural areas of tropical and subtropical countries. The true magnitude of the public health threat posed by snakebites is unknown, making it difficult for public health officials to optimize prevention and treatment. The objective of this work was to conduct a systematic review of the literature to gather data on snakebite epidemiology in the Amazon region and describe a case series of snakebites from epidemiological surveillance in the State of Amazonas (1974-2012. Only 11 articles regarding snakebites were found. In the State of Amazonas, information regarding incidents involving snakes is scarce. Historical trends show an increasing number of cases after the second half of the 1980s. Snakebites predominated among adults (20-39 years old; 38%, in the male gender (78.9% and in those living in rural areas (85.6%. The predominant snake envenomation type was bothropic. The incidence reported by the epidemiological surveillance in the State of Amazonas, reaching up to 200 cases/100,000 inhabitants in some areas, is among the highest annual snakebite incidence rates of any region in the world. The majority of the cases were reported in the rainy season with a case-fatality rate of 0.6%. Snakebite envenomation is a great disease burden in the State of Amazonas, representing a challenge for future investigations, including approaches to estimating incidence under-notification and case-fatality rates as well as the factors related to severity and disabilities.

    a prueba ésta hipótesis. M. praecox constituye el único registro para la vertiente del Catatumbo, pero es muy probable que se encuentren representadas otras especies de la vertiente del Caribe. Se recomienda la realización de estudios moleculares interpoblacionales para las especies que se encuentran tanto en la vertiente del Orinoco como en la del Amazonas, para poder establecer con certeza si diferencias consideradas como intraespecíficas puedan tratarse de diferencias interespecíficas. El número de especies de éste género registradas para Colombia puede ser mayor al presentado en éste trabajo, esencialmente por sus características geográficas, y a la escasez de estudios de éste grupo en el país. Esto plantea la necesidad de establecer colecciones en diversas cuencas, por ejemplo las cuencas de los ríos Cauca y Atrato en la vertiente del Caribe, las cuencas de los ríos Tomo y Vichada en la vertiente del Orinoco, la cuenca del río Putumayo en la vertiente del Amazonas, y en toda la vertiente del Catatumbo.

    Full Text Available Hantavirus disease is caused by the hantavirus, which is an RNA virus belonging to the family Bunyaviridae. Hantavirus disease is an anthropozoonotic infection transmitted through the inhalation of aerosols from the excreta of hantavirus-infected rodents. In the county of Itacoatiara in the state of Amazonas (AM, Brazil, the first human cases of hantavirus pulmonary and cardiovascular syndrome were described in July 2004. These first cases were followed by two fatal cases, one in the municipality of Maués in 2005 and another in Itacoatiara in 2007. In this study, we investigated the antibody levels to hantavirus in a population of 1,731 individuals from four different counties of AM. Sera were tested by IgG/IgM- enzyme-linked immune-sorbent assay using a recombinant nucleocapsid protein of the Araraquara hantavirus as an antigen. Ten sera were IgG positive to hantavirus (0.6%. Among the positive sera, 0.8% (1/122, 0.4% (1/256, 0.2% (1/556 and 0.9% (7/797 were from Atalaia do Norte, Careiro Castanho, Itacoatiara and Lábrea, respectively. None of the sera in this survey were IgM-positive. Because these counties are distributed in different areas of AM, we can assume that infected individuals are found throughout the entire state, which suggests that hantavirus disease could be a local emerging health problem.

    Organophosphate and carbamate pesticides inhibit acetylcholinesterase (AChE) at nerve synapses. Blood samples from 22 Hispaniolan Amazon parrots (Amazona ventralis) were assayed for cholinesterase levels by two different techniques. Using the modified Michel method, the whole-blood cholinesterase activity levels ranged from 0.082 to 0.616 deltapH/hr with a mean value of 0.35 deltapH/hr. A reference range (0.08-0.62 deltapH/hr) for cholinesterase was established in birds. The modified Ellman spectrophotometric method was used to measure AChE activity by adding acetylthiocholine or pseudocholinesterase (plasma cholinesterase) activity by adding butyrylthiocholine. The reference range of the AChE activity using the modified Ellman spectrophotometric method was 0-1.12 micromol/ml/min with a mean of 0.48 micromol/ml/min, and for pseudocholinesterase the range was 0.09-0.98 micromol/ml/min with a mean of 0.53 micromol/ml/min.

    OBJECTIVE-To evaluate the analgesic efficacy of meloxicam in parrots with experimentally induced arthritis, with extent of weight bearing and rotational perch walking used as outcome measures. ANIMALS-15 adult Hispaniolan parrots (Amazona ventralis). PROCEDURES-Arthritis was experimentally induced via intra-articular injection of microcrystalline sodium urate suspension (MSU) into 1 intertarsal joint. Parrots were treated in a crossover design. Five treatments were compared as follows: meloxicam (4 dosages) at 0.05, 0.1, 0.5, and 1.0 mg/kg (IM, q 12 h, 3 times) and 0.03 mL of saline (0.9% NaCl) solution (IM, q 12 h, 3 times). The first treatment was given 6 hours following MSU administration. Lameness was assessed by use of a biomechanical perch to record weight-bearing load and a rotational perch to determine dexterity. Feces were collected to assay for occult blood. RESULTS-Parrots treated with meloxicam at 1.0 mg/kg had significantly better return to normal (baseline) weight bearing on the arthritic pelvic limb, compared with control parrots or parrots treated with meloxicam at 0.05, 0.1, and 0.5 mg/kg. All fecal samples collected from parrots following induction of arthritis and treatment with meloxicam had negative results for occult blood. CONCLUSIONS AND CLINICAL RELEVANCE-Meloxicam administered at 1.0 mg/kg, IM, every 12 hours effectively relieved arthritic pain in parrots.

    Full Text Available The lack of information concerning the variability of soil properties has been a major concern of researchers in the Amazon region. Thus, the aim of this study was to evaluate the spatial variability of soil chemical properties and determine minimal sampling density to characterize the variability of these properties in five environments located in the south of the State of Amazonas, Brazil. The five environments were archaeological dark earth (ADE, forest, pasture land, agroforestry operation, and sugarcane crop. Regular 70 × 70 m mesh grids were set up in these areas, with 64 sample points spaced at 10 m distance. Soil samples were collected at the 0.0-0.1 m depth. The chemical properties of pH in water, OM, P, K, Ca, Mg, H+Al, SB, CEC, and V were determined at these points. Data were analyzed by descriptive and geostatistical analyses. A large part of the data analyzed showed spatial dependence. Chemical properties were best fitted to the spherical model in almost all the environments evaluated, except for the sugarcane field with a better fit to the exponential model. ADE and sugarcane areas had greater heterogeneity of soil chemical properties, showing a greater range and higher sampling density; however, forest and agroforestry areas had less variability of chemical properties.

    Full Text Available Local anesthetic procedures are commonly used in domestic and wild birds, because of its low cost and fast induction, as long as applied with great precision, which requires specific anatomical knowledge of the site of incision. This study aimed to establish the origin and distribution of the brachial plexus of the Blue-fronted Parrot (Amazona aestiva by anatomic dissection of the skin and musculature of 22 specimens (17 males and 5 females from the Wild Animals Screening Center of the Federal District after death by natural causes. The dissection work promoted the isolation of the forming roots of the brachial plexus, as well as its ramifications. The brachial plexus was formed by four trunks, including the ventral spinal cord rami segments from C9 to C10, C10 to C11, C11 to T1 and T1 to T2, which joined into a short common trunk, branched into dorsal and ventral cords. The thin nerves subcoracoideus and subscapularis and the branch to the scapulohumeralis muscle originated from the common trunk. The dorsal cord originated the anconeal, axillaris and radialis nerves, while the ventral cord gave origin for the pectoralis cranialis, pectoralis caudalis, coracobrachialis and medianoulnaris. These branches innervated the muscles of the extensor and flexor compartments of the forelimb, pectoral muscles and overlying skin.

    The conodont color alteration index (CAI) was determined in elements from core samples of the Frasnian Barreirinha Formation (one well) and of the Pennsylvanian-Permian Tapajós Group (twenty three wells and one limestone quarry) in the Amazonas Basin. The thermal history of the basin is analyzed using the CAI value distribution represented in maps and stratigraphic sections through correlation schemes, and in conjunction with previously published data. The pattern of palaeotemperatures for CAI values of 1.5-3 is coincident with organic matter maturation under a sedimentary overburden providing diagenetic conditions in the oil/gas window. Locally, conodonts show metamorphism (CAI value of 6-7) in relation to the intrusion of diabase bodies in beds including high geothermal gradient evaporites. Microtextural alteration on the surface conodonts commonly shows several types of overgrowth microtextures developed in diagenetic conditions. Locally, recrystallization in conodonts with a high CAI value is congruent with contact metamorphism in relation to Mesozoic intrusions. The CAI values of 1.5 or 2 observed close to the surface in several areas of the basin may be interpreted in relation to a high thermal palaeogradient derived from the magmatic episode or/and to the local denudation of the upper part of the Paleozoic succession prior to this thermal event.

    A survey was conducted with 521 undergraduate health sciences students from the Federal University in Amazonas, Manaus, Brazil. Lifetime alcohol consumption was reported by 87.7% students, as compared to 30.7% for tobacco, with the latter reported more frequently by males (39.7%). The most common illicit drugs were solvents (11.9%), marijuana (9.4%), amphetamines and anxiolytics (9.2% each), cocaine (2.1%), and hallucinogens (1.2%). The main reason for illicit drug use was curiosity. Lifetime use of anabolic steroids was reported by 2.1% of the students. Alcohol abuse in the previous 30 days was reported by 12.4% of the students. Events following drinking included: fights (4.7%), accidents (2.4%), classroom absenteeism (33.7%), and job absenteeism (11.8%). Another important finding was that 47.3% of students drove after drinking. Opinions on drug abuse and patterns agree with those from similar studies in other regions of Brazil.

    The biodiversity of the Amazon region includes many species of arthropod vectors in different ecotopes, thus enabling occurrences of diseases like malaria, filariasis and arbovirosis. From August 2001 to July 2002, we gathered culicids from inside homes, from areas surrounding these homes and from forested areas of the São João Community, in the rural zone of Manaus, State of Amazonas. 1240 specimens were collected, belonging to the Culicinae (99%) and Anophelinae (1%) subfamilies, with 50 species. The Culicini tribe clearly predominated, with 904 specimens (72.9%), and the species Culex usquatus (22.6%) and Culex quinquefasciatus (17.7%) were prominent. Out of the total number of culicids, 1,077 (86.9%) were caught in the forests, 101 (8.1%) in the areas surrounding homes and 62 (5%) inside homes. Forests were the ecotope that presented the highest species diversity. The presence of Anopheles darlingi, Anopheles triannulatus, Aedes aegypti, Haemagogus janthinomys and other proven or potential vectors was recorded.

    A 37-year-old female yellow-headed Amazon parrot (Amazona ochrocephala oratrix) was presented after a 4-month-period behavior change and intermittent episodes of obtunded mentation. Clinical findings on physical examination included ataxia, a weak grasp, and reluctance to move. Results of magnetic resonance imaging were consistent with severe hydrocephalus without evidence of cerebrospinal fluid obstruction. The bird was treated with tapering dosages of prednisolone over a 4-month period, during which time the episodes did not occur. Discontinuation of treatment was attempted several times but resulted in relapse. After 3.5 years of maintenance treatment with prednisolone, the bird was presented subsequent to a 5-hour episode of obtunded mentation and worsening neurologic signs. Despite increasing the dose of prednisolone and providing additional supportive care, the bird's condition worsened, and euthanasia was elected. Necropsy findings included severe hydrocephalus with significant loss of right cerebral parenchyma and no evidence of cerebrospinal fluid obstruction. Histologic examination of the remaining cerebral parenchyma revealed a moderate, multifocal, cellular infiltrate; encephalomalacia; fibrosis; and hemosiderosis in tissue adjacent to the distended ventricles. Other findings included hepatic vacuolar degeneration. Diagnostic imaging and postmortem findings were consistent with a diagnosis of hydrocephalus ex vacuo. To our knowledge, this is the first report of hydrocephalus in an Amazon parrot as well as the first report of hydrocephalus in any avian species associated with long-term follow-up and prolonged corticosteroid treatment.

    To investigate renal, gastrointestinal, and hemostatic effects associated with oral administration of multiple doses of meloxicam to healthy Hispaniolan Amazon parrots (Amazona ventralis). 12 Hispaniolan Amazon parrots. Birds were assigned to receive meloxicam oral suspension (1.6 mg/kg, PO, q 12 h) and 2.5 mL of tap water inserted into the crop by use of a gavage tube (n = 8) or the equivalent volume of tap water only (control group; 4) for 15 days. Urine and feces were collected 2 hours after treatment administration each day. Feces were evaluated for occult blood. Results of a CBC and serum biochemical analysis and measured N-acetyl-β-d-glucosaminidase (NAG) activity and whole blood clotting time were evaluated before, during, and after completion of treatments. Results of urinalysis and measured urine NAG activity were also evaluated. Birds treated with meloxicam had a significant increase in number of WBCs and decrease in PCV from before to after treatment. The PCV also decreased significantly, compared with results for the control group; however, WBC count and PCV for all birds remained within reference ranges throughout the study. One parrot treated with meloxicam had a single high value for urine NAG activity. Meloxicam administered orally at the dosage used in this study caused no apparent negative changes in several renal, gastrointestinal, or hemostatic variables in healthy Hispaniolan Amazon parrots. Additional studies to evaluate adverse effects of NSAIDs in birds will be needed.

    A feral green-cheeked Amazon parrot (Amazona viridigenalis), also known as the red-crowned Amazon, with generalized neurologic symptoms was found in Pasadena in Southern California and brought in for treatment. The bird was refractory to a wide variety of medications and supportive treatment. Tests for polyoma virus, psittacine beak and feather disease virus, and West Nile virus as well as Chlamydophila psittaci were negative. Hospitalized and home care continued for a total of 69 days. The bird was rehospitalized on day 66 for increasing severity of clinical signs and found 3 days later hanging with its head down, in respiratory arrest. Resuscitation was unsuccessful. There were no gross pathologic lesions. Histopathology showed a focal subcutaneous fungal caseous granuloma under the skin of the dorsum. Many sarcocysts morphologically consistent with Sarcocystis falcatula were found in the cytoplasm of the skeletal myofibers from skeletal muscles of different locations of this bird, a finding that was considered an incidental, clinically nonsignificant finding in this case. Necrosis with microscopic lesions typical of Baylisascaris spp. neural larva migrans was in the brain. Although multiple histologic serial sections of the brain were examined and a brain squash performed and analyzed, no Baylisascaris larvae were found. This is the first presumptive case of Baylisascaris in a feral psittacine.

    To evaluate the pharmacokinetics of nalbuphine decanoate after IM administration to Hispaniolan Amazon parrots (Amazona ventralis). 9 healthy adult Hispaniolan Amazon parrots of unknown sex. Nalbuphine decanoate (37.5 mg/kg) was administered IM to all birds. Plasma samples were obtained from blood collected before (time 0) and 0.25, 1, 2, 3, 6, 12, 24, 48, and 96 hours after drug administration. Plasma samples were used for measurement of nalbuphine concentrations via liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were estimated with computer software. Plasma concentrations of nalbuphine increased rapidly after IM administration, with a mean concentration of 46.1 ng/mL at 0.25 hours after administration. Plasma concentrations of nalbuphine remained > 20 ng/mL for at least 24 hours in all birds. The maximum plasma concentration was 109.4 ng/mL at 2.15 hours. The mean terminal half-life was 20.4 hours. In Hispaniolan Amazon parrots, plasma concentrations of nalbuphine were prolonged after IM administration of nalbuphine decanoate, compared with previously reported results after administration of nalbuphine hydrochloride. Plasma concentrations that could be associated with antinociception were maintained for 24 hours after IM administration of 37.5 mg of nalbuphine decanoate/kg. Safety and analgesic efficacy of nalbuphine treatments in this species require further investigation to determine the potential for clinical use in pain management in psittacine species.

    To assess the pharmacokinetics of nalbuphine HCl after IV and IM administration to Hispaniolan Amazon parrots (Amazona ventralis). 8 healthy adult Hispaniolan Amazon parrots of unknown sex. Nalbuphine HCl (12.5 mg/kg) was administered IV and IM to all birds in a complete randomized crossover study design; there was a washout period of 21 days between subsequent administrations. Plasma samples were obtained from blood collected at predetermined time points for measurement of nalbuphine concentration by use of liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were estimated by use of computer software. Nalbuphine was rapidly eliminated with a terminal half-life of 0.33 hours and clearance of 69.95 mL/min/kg after IV administration and a half-life of 0.35 hours after IM administration. Volume of distribution was 2.01 L/kg after IV administration. The fraction of the dose absorbed was high (1.03) after IM administration. No adverse effects were detected in the parrots during the study. In Hispaniolan Amazon parrots, nalbuphine appeared to have good bioavailability after IM administration and was rapidly cleared after IV and IM administration. Safety and analgesic efficacy of various nalbuphine treatment regimens in this species require further investigation to determine the potential for clinical palliation of signs of pain in psittacine species.

    To determine the antinociceptive and sedative effects of tramadol in Hispaniolan Amazon parrots (Amazona ventralis) following IV administration. 11 healthy Hispaniolan Amazon parrots of unknown sex. Tramadol hydrochloride (5 mg/kg, IV) and an equivalent volume (≤ 0.34 mL) of saline (0.9% NaCl) solution were administered to parrots in a complete crossover study design. Foot withdrawal response to a thermal stimulus was determined 30 to 60 minutes before (baseline) and 15, 30, 60, 120, and 240 minutes after treatment administration; agitation-sedation scores were determined for parrots at each of those times. The estimated mean changes in temperature from the baseline value that elicited a foot withdrawal response were 1.65° and -1.08°C after administration of tramadol and saline solution, respectively. Temperatures at which a foot withdrawal response was elicited were significantly higher than baseline values at all 5 evaluation times after administration of tramadol and were significantly lower than baseline values at 30, 120, and 240 minutes after administration of saline solution. No sedation, agitation, or other adverse effects were observed in any of the parrots after administration of tramadol. Tramadol hydrochloride (5 mg/kg, IV) significantly increased the thermal nociception threshold for Hispaniolan Amazon parrots in the present study. Sedation and adverse effects were not observed. These results are consistent with results of other studies in which the antinociceptive effects of tramadol after oral administration to parrots were determined.

    Neuropathic pain is a manifestation of chronic pain that arises with damage to the somatosensory system. Pharmacologic treatment recommendations for alleviation of neuropathic pain are often multimodal, and the few reports communicating treatment of suspected neuropathic pain in avian patients describe the use of gabapentin as part of the therapeutic regimen. To determine the pharmacokinetics of gabapentin in Hispaniolan Amazon parrots ( Amazona ventralis ), compounded gabapentin suspensions were administered at 30 mg/kg IV to 2 birds, 10 mg/kg PO to 3 birds, and 30 mg/kg PO to 3 birds. Blood samples were collected immediately before and at 9 different time points after drug administration. Plasma samples were analyzed for gabapentin concentration, and pharmacokinetic parameters were calculated with both a nonlinear mixed-effect approach and a noncompartmental analysis. The best compartmental, oral model was used to simulate the concentration-time profiles resulting from different dosing scenarios. Mild sedation was observed in both study birds after intravenous injection. Computer simulation of different dosing scenarios with the mean parameter estimates showed that 15 mg/kg every 8 hours would be a starting point for oral dosing in Hispaniolan Amazon parrots based on effective plasma concentrations reported for human patients; however, additional studies need to be performed to establish a therapeutic dose.

    The purpose of this study was to establish a technique for collecting semen from blue-fronted Amazon parrots (Amazona aestiva aestiva) and to evaluate the samples that were collected. The massage method is the most common technique used to collect semen in birds and has been proven successful in several psittacine species; however, collection attempts in larger parrots have been unsatisfactory. Six blue-fronted Amazon parrot males, 3 paired with hens and 3 unpaired, were used in this study. The semen collection technique was revised to allow collection from individual birds by a single person. Semen collection was attempted from the 6 parrots on 52-56 occasions, which totaled 330 single attempts. Nineteen ejaculates were collected, and each bird produced at least 1 ejaculate that contained spermatozoa. Large ranges of sample volume (1-15.4 microL), sperm quality (motility = 2%-60%; live:dead ratio = 2:198 to 185:15), sperm concentration (0.79-3.3 x 10(6) sperm/mL), and contamination rate (0%-100%) were observed. Measured parameters did not appear to be significantly impacted by birds being paired or kept singly. Because of the relatively short acclimation period, the birds appeared to be sexually inactive for the majority of the study. Further research using sexually active birds will be necessary to determine standard spermatological parameters and verify the success of the methodology used here.

    A 25-year-old intact female orange-winged Amazon parrot (Amazona amazonica) presented for a 2-week history of straining to defecate, lethargy, open-beak breathing, decreased vocalization, and ruffled feathers. On physical examination, the parrot had a heart murmur, increased air sac and lung sounds, open-beak breathing, increased respiratory rate and effort, and coelomic distension. An ultrasound revealed intracoelomic fluid, and hemorrhagic fluid was aspirated from the coelom. Cytologic analysis indicated hemocoelom. Pericardial effusion was observed during the sonogram, and pericardiocentesis was performed. The bird was euthanatized upon the owner's request because of a poor prognosis. At necropsy, several masses that involved the ovary and oviduct were observed, as well as a thickened pericardium and a thickened, fibrinous epicardium. Results of a histopathologic examination of the masses that involved the reproductive tract revealed ovarian hemangiosarcoma, which was confirmed by immunohistochemical staining. To our knowledge, ovarian hemangiosarcoma has not been reported in a psittacine species, nor has immunohistochemistry confirmed ovarian hemangiosarcoma in avian species, specifically in an orange-winged Amazon parrot.

    To evaluate the relationship between osmolality and specific gravity of urine samples from clinically normal adult parrots and to determine a formula to convert urine specific gravity (USG) measured on a reference scale to a more accurate USG value for an avian species, urine samples were collected opportunistically from a colony of Hispaniolan Amazon parrots (Amazona ventralis). Samples were analyzed by using a veterinary refractometer, and specific gravity was measured on both canine and feline scales. Osmolality was measured by vapor pressure osmometry. Specific gravity and osmolality measurements were highly correlated (r = 0.96). The linear relationship between refractivity measurements on a reference scale and osmolality was determined. An equation was calculated to allow specific gravity results from a medical refractometer to be converted to specific gravity values of Hispaniolan Amazon parrots: USGHAp = 0.201 +0.798(USGref). Use of the reference-canine scale to approximate the osmolality of parrot urine leads to an overestimation of the true osmolality of the sample. In addition, this error increases as the concentration of urine increases. Compared with the human-canine scale, the feline scale provides a closer approximation to urine osmolality of Hispaniolan Amazon parrots but still results in overestimation of osmolality.

    An approximately 30-year-old male spectacled Amazon parrot (Amazona albifrons) was presented with a 2-week history of ataxia, head shaking, weight loss and seizures. Gross findings on necropsy examination included atrophy of the musculature, ruffled feathers and minimal epicardial and abdominal fat. Microscopically, there were perivascular cuffs of macrophages with fewer lymphocytes in the grey and white matter of the brain and spinal cord. These lesions were accompanied by gliosis and mild vacuolation of the white matter. In the small intestine, up to 70% of the intestinal ganglia were effaced by infiltrates of macrophages and fewer lymphocytes. The intestinal lamina propria contained multiple inflammatory aggregates of a similar nature. Ziehl-Neelsen staining revealed the presence of numerous bacilli within the cytoplasm of macrophages in the central nervous system (CNS) and enteric ganglia. Amplification of the DNAJ gene confirmed a mycobacterial infection and subsequent polymerase chain reaction (PCR) using a species-specific primer confirmed the aetiology as Mycobacterium genavense. Infection of the CNS with Mycobacterium spp. is uncommon and has not been previously reported in a parrot. This case is unusual in that the organism exhibited tropism for neural tissue.

    To determine pharmacokinetics after oral administration of a single dose of terbinafine hydrochloride to Hispaniolan Amazon parrots (Amazona ventralis). 6 healthy adult Hispaniolan Amazon parrots. A single dose of terbinafine hydrochloride (60 mg/kg) was administered orally to each bird, which was followed immediately by administration of a commercially available gavage feeding formula. Blood samples were collected at the time of drug administration (time 0) and 0.25, 0.5, 1, 2, 4, 8, 12, and 24 hours after drug administration. Plasma concentrations of terbinafine were determined via high-performance liquid chromatography. Data from 1 bird were discarded because of a possible error in the dose of drug administered. After oral administration of terbinafine, the maximum concentration for the remaining 5 fed birds ranged from 109 to 671 ng/mL, half-life ranged from 6 to 13.5 hours, and time to the maximum concentration ranged from 2 to 8 hours. No adverse effects were observed. Analysis of the results indicated that oral administration of terbinafine at a dose of 60 mg/kg to Amazon parrots did not result in adverse effects and may be potentially of use in the treatment of aspergillosis. Additional studies are needed to determine treatment efficacy and safety.

    Thromboelastography (TEG) provides a global assessment of coagulation, including the rate of clot initiation, clot kinetics, achievement of maximum clot strength, and fibrinolysis. Thromboelastography (TEG) is used with increasing frequency in the field of veterinary medicine, although its usefulness in avian species has not been adequately explored. The purpose of this preliminary study was to assess the applicability of TEG in psittacine birds. Kaolin-activated TEG was used to analyze citrated whole blood collected routinely from 8 healthy adult Hispaniolan Amazon parrots ( Amazona ventralis ). The minimum and maximum TEG values obtained included time to clot initiation (2.6-15 minutes), clot formation time (4.3-20.8 minutes), α angle (12.7°-47.9°), maximum amplitude of clot strength (26.3-46.2 mm), and percentage of lysis 30 minutes after achievement of maximum amplitude (0%-5.3%). The TEG values demonstrated comparative hypocoagulability relative to published values in canine and feline species. Differences may be explained by either the in vitro temperature at which TEG is standardly performed or the method of activation used in this study. Although TEG may have significant advantages over traditional coagulation tests, including lack of need for species-specific reagents, further evaluation is required in a variety of avian species and while exploring various TEG methodologies before this technology can be recommended for use in clinical cases.

    Contrast fluoroscopy is a valuable tool to examine avian gastrointestinal motility. However, the lack of a standardized examination protocol and reference ranges prevents the objective interpretation of motility disorders and other gastrointestinal abnormalities. Our goals were to evaluate gastrointestinal motility in 20 Hispaniolan Amazon parrots (Amazona ventralis) by contrast fluoroscopy. Each parrot was crop-fed an equal part mixture of barium sulfate and hand-feeding formula and placed in a cardboard box for fluoroscopy. Over a 3-h period, 1.5 minute segments of lateral and ventrodorsal fluoroscopy were recorded every 30 min. The gastric cycle and patterns of intestinal motility were described. The frequency of crop contractions, esophageal boluses, and gastric cycles were determined in lateral and ventrodorsal views. A range of 3.4-6.6 gastric cycles/min was noted on the lateral view and 3.0-6.6 gastric cycles/min on the ventrodorsal view. Circular measurements of the proventriculus diameter, ventriculus width, and length were obtained using the midshaft femoral diameter as a standard reference unit. The upper limits of the reference ranges were 3.6 and 4.7 femoral units for the proventriculus diameter in the lateral and ventrodorsal view, respectively. Two consecutive measurements were obtained and the measurement technique was found to have high reproducibility. In this study, we established a standardized protocol for contrast fluoroscopic examination of the gastrointestinal tract and a reliable measurement method of the proventriculus and ventriculus using femoral units in the Hispaniolan Amazon parrot.

    A 37-year-old female yellow-naped Amazon parrot (Amazona auropalliata) was presented with a history of lethargy, inappetence, and decreased vocalizations. On examination, the coelom was moderately distended and palpated fluctuant, and the heart was muffled on auscultation. Coelomic ultrasound, coelomocentesis, and radiographs were performed and revealed an enlarged cardiac silhouette and marked coelomic effusion. Pericardial effusion was confirmed by echocardiography. A well-circumscribed, hyperechoic soft tissue density was observed at the level of the right atrium on initial echocardiography; however, a cardiac mass was not identified by computed tomography scan or repeat echocardiograms. Ultrasound-guided pericardiocentesis was performed under anesthesia, and cytology results were consistent with hemorrhage; no neoplastic cells were identified. A repeat echocardiogram 4 days after pericardiocentesis revealed recurrence of the pericardial effusion. Due to the grave prognosis, the owners declined endoscopic pericardiectomy, and the patient died the following day. On postmortem examination, the pericardial surface of the heart was covered in a white to yellow, multinodular mass layer. Histologic analysis revealed a multinodular mass extending from the atria, running along the epicardium distally, and often extending into the myocardium. Neoplastic cells present in the heart mass and pericardium did not stain with a Churukian-Schenk stain, and thyroglobulin immunohistochemistry was negative. Cytokeratin and vimentin stains showed positive expression in the neoplastic cells within the mass. These results are consistent with a diagnosis of mesothelioma. This is the first report of mesothelioma in a psittacine bird.

    Positron emission tomography (PET) is often used to stage and monitor human cancer and has recently been used in a similar fashion in veterinary medicine. The most commonly used radiopharmaceutical is 2-Deoxy-2-[(18) F]-Fluoro-d-glucose ((18) F-FDG), which is concentrated and trapped within cells that use glucose as their energy substrate. We characterized the normal distribution of (18) F-FDG in 10 healthy Hispaniolan Amazon parrots (Amazona ventralis) by performing whole body PET scans at steady state, 60min after injection. Significant variability was found in the intestinal activity. Avian species are known to reflux fluid and electrolytes from their cloaca into their colon. To evaluate reflux as the cause of variability in intestinal distribution of (18) F-FDG, dynamic PET scans were performed on the coelomic cavity of six Hispaniolan Amazon parrots from time 0 to 60min postinjection of radiotracer. Reflux of radioactive material from the cloaca into the colon occurred in all birds to varying degrees and occurred before 60min. To evaluate the intestinal tract of clinical avian patients, dynamic scans must be performed starting immediately after injection so that increased radioactivity due to metabolism or hypermetabolic lesions such as cancer can be differentiated from increased radioactivity due to reflux of fluid from the cloaca. © 2010 Veterinary Radiology & Ultrasound.

    A 30-year-old Salvin's Amazon parrot (Amazona autumnalis salvini) with a history of a lifelong poor diet and inappropriate housing was presented in lateral recumbency to a veterinary teaching hospital for further evaluation. Radiological and ultrasonographic examination revealed a mild proventricular dilatation, mild hepatomegaly, signs of enteritis and airsacculitis. The main laboratory findings included a mild macrocytic hyperchromic anaemia, hypoglobulinaemia, decreased bile acids and increased alkaline phosphatase. In this bird a liver pathology was suspected because of the clinical, laboratory and ultrasonographic findings. The bird was treated with supportive care and metabolic aids. After initial improvement of the clinical signs, the bird's condition deteriorated and it died. Pathological findings revealed an endocarditis and myocarditis due to Lactobacillus jensenii and a bacteraemia. Endocarditis due to Lactobacillus sp. is a rare phenomenon in humans not yet described in animals. It is associated with severe underlying illnesses leading to translocation of otherwise non-pathogenic bacteria in the bloodstream. A similar pattern might be assumed in animals with compromised immunity.

    A 25-year-old, male mealy Amazon parrot (Amazona farinose) with a history of polycythemia, hepatomegaly, and epistaxis was evaluated for progressive lethargy and anorexia. Clinical laboratory testing revealed severe polycythemia (71%), hypophosphatemia (1.6 mg/dL), and mild hypokalemia (2.8 mEq/L). Radiographs showed marked hepatomegaly and loss of air sac space. Despite supportive treatments, the bird's condition deteriorated, and it developed ataxia, was unable to fly, and became oxygen dependent. An echocardiogram, including an air bubble study, revealed a right-to-left atrial shunt and presumed pulmonary arterial hypertension. The bird was started on periodic phlebotomy (5-10 mL/kg q6wk) to reduce packed cell volume and sildenafil citrate (2.5 mg/kg PO q8h) for treatment of suspected pulmonary arterial hypertension. One week later, the patient was weaned off oxygen, and 24 days after initial presentation, the parrot was returned to its outdoor exhibit. Intermittent periods of increased respiratory rate and effort have been reported but have resolved without additional treatments. Epistaxis, once common in this bird, has not been noted since initiating treatment with sildenafil citrate 15 months ago.

    This report describes exocrine pancreatic insufficiency in a yellow-naped Amazon (Amazona ochrocephala) with complete effacement of the pancreas by a pancreatic adenocarcinoma. The bird presented with a 3-month history of weight loss and voluminous, foul-smelling droppings. Clinically, routine hematologic findings were normal and fecal tests were performed to evaluate exocrine pancreatic function. The fecal function tests were positive for neutral and split fats and negative for trypsin. Oral administration of corn oil did not result in elevation of blood triglyceride levels. Two days later, the triglyceride tolerance test was repeated using corn oil mixed with pancreatic enzymes. This time, there was a 70% elevation of blood triglyceride levels. Because of a poor prognosis, the bird was euthanatized. At necropsy, the pancreas was diffusely enlarged, white, nodular, and firm. The liver contained multiple, 1-2-mm-diameter, randomly located, tan nodules. Microscopically, the pancreas was effaced by numerous lobules of neoplastic ductular structures surrounded by abundant fibrous connective tissue. In the liver, the hepatic parenchyma was replaced by multiple, well-demarcated, nonencapsulated foci of neoplastic tissue similar to that in the pancreas.

    Full Text Available Chagas disease (CD is a parasitic infection that originated in the Americas and is caused by Trypanosoma cruzi. In the last few years, the disease has spread to countries in North America, Asia and Europe due to the migration of Latin Americans. In the Brazilian Amazon, CD has an endemic transmission, especially in the Rio Negro region, where an occupational hazard was described for piaçaveiros (piassaba gatherers. In the State of Amazonas, the first chagasic infection was reported in 1977, and the first acute CD case was recorded in 1980. After initiatives to integrate acute CD diagnostics with the malaria laboratories network, reports of acute CD cases have increased. Most of these cases are associated with oral transmission by the consumption of contaminated food. Chronic cases have also been diagnosed, mostly in the indeterminate form. These cases were detected by serological surveys in cardiologic outpatient clinics and during blood donor screening. Considering that the control mechanisms adopted in Brazil's classic transmission areas are not fully applicable in the Amazon, it is important to understand the disease behavior in this region, both in the acute and chronic cases. Therefore, the pursuit of control measures for the Amazon region should be a priority given that CD represents a challenge to preserving the way of life of the Amazon's inhabitants.

    Full Text Available El erotismo, una creación cultural de cada sociedad, se dio en el proceso de evolución de las especies a través del dominio del instinto sexual reproductor por el hombre transformándolo en una representación mediada en el y por el conjunto de censuras, prácticas, rituales, mitos y tabúes, lo que nos separa de los demás animales. Es experimentado por individuos considerados “normales” y por individuos discapacitados de distintas etnias, culturas, edades y clases sociales. Intento propiciar una reflexión acerca del ethos del patriarcado presente en las dificultades encontradas por los individuos al experimentar el amor erótico. Creo que es importante invertir en políticas públicas para cambiar del paradigma que considera la discapacidad como fenómeno individual al paradigma de las diversidades educativas, sociales, políticas y sexuales; expandir la información en el ámbito familiar, educativo y de los medios, para crear nuevas estructuras de experiencia del amor erótico.

Esta información es necesaria para diseñar acciones específicas de restauración y conservación. Durante diez años estudiamos la ecología de anidación del loro en Michoacán, México. Las variables estudiadas incluyeron en escala local las especies de árboles-nido, sus dimensiones y posición geográfica, dieta y estructura de parches de bosque; y a mayor escala el uso de la vegetación y las variables climáticas asociadas a la distribución de árboles-nido, obtenidas con un modelo de nicho ecológico utilizando Maxent. También evaluamos la tolerancia del loro al manejo de la tierra, y comparamos los árboles-nido encontrados, con 18 árboles-nido de Tamaulipas (Golfo de México, estudiados en los ochentas en un rancho privado intensamente manejado. Los loros anidaron en árboles altos en cavidades del dosel, registramos 92 árboles-nido en 11 especies de árboles, pero el 72.8% se presentó en Astronium graveolens y Enterolobium cyclocarpum que califican como árboles clave. Los bosques de anidación presentan 54 especies de árboles como máximo, y 50% sirven como alimento, también las zonas presentan alta abundancia de árboles dieta. La menor riqueza de árboles y de árboles dieta se presentó en un rancho ganadero, mientras que las áreas en regeneración natural presentaron mayor riqueza. La altura de la entrada de la cavidad en los árboles-nido del Pacífico fue mayor que en los del Golfo de México. Hipotetizamos que las diferencias se deben al comportamiento del loro, adaptado a la presión diferencial de saqueo de nidos y disponibilidad de cavidades. Los árboles-nido se encontraron en seis tipos de vegetación, pero el loro prefirió el bosque tropical subcaducifolio conservado, y ribereño, anidó menos en bosque

    Red-bellied piranhas (Pygocentrus nattereri) are widely caught with different intensities throughout the region of Solimões-Amazonas River by local fishermen. Thus, the management of this resource is performed in the absence of any information on its genetic stock. P. nattereri is a voracious predator and widely distributed in the Neotropical region, and it is found in other regions of American continent. However, information about genetic variability and structure of wild populations of red-bellied piranha is unavailable. Here, we describe the levels of genetic diversity and genetic structure of red-bellied piranha populations collected at different locations of Solimões-Amazonas River system. We collected 234 red-bellied piranhas and analyzed throughout eight microsatellite markers. We identified high genetic diversity within populations, although the populations of lakes ANA, ARA, and MAR have shown some decrease in their genetic variability, indicating overfishing at these communities. Was identified the existence of two biological populations when the analysis was taken altogether at the lakes of Solimões-Amazonas River system, with significant genetic differentiation between them. The red-bellied piranha populations presented limited gene flow between two groups of populations, which were explained by geographical distance between these lakes. However, high level of gene flow was observed between the lakes within of the biological populations. We have identified high divergence between the Catalão subpopulation and all other subpopulations. We suggest the creation of sustainable reserve for lakes near the city of Manaus to better manage and protect this species, whose populations suffer from both extractive and sport fishing.

    An adult, male double yellow-headed Amazon parrot (Amazona ochrocephala oratrix) was diagnosed with chronic lymphocytic leukemia based on results of a complete blood cell count and cytologic examination of a bone marrow aspirate. Treatment with oral chlorambucil was attempted, but no response was evident after 40 days. The bird was euthanatized, and the diagnosis of chronic lymphocytic leukemia was confirmed on gross and microscopic examination of tissues. Neoplastic lymphocytes were found in the bone marrow, liver, kidney, testes, and blood vessels. Based on CD3-positive immunocytochemical and immunohistochemical immunophenotyping, the chronic lymphocytic leukemia was determined to be of T-cell origin.

  9. Characterization and genesis of waterfalls of the Presidente Figueiredo region, Northeast State of Amazonas, Brazil

    Directory of Open Access Journals (Sweden)

    AFONSO C. R. NOGUEIRA

    2001-06-01

    Full Text Available The waterfalls of the Presidente Figueiredo municipality represent a fascinating natural scenery of northeast state of Amazonas, northern Brazil. The falls, generally less than 10m high, are developed on siliciclastic rocks of the Nhamundá (Lower Silurian, and Manacapuru (Upper Silurian - Lower Devonian formations. Morphological and structural analyses of these features indicate that most of them originated through Quaternary neotectonics and are installed in NE-trending normal fault escarpments. Waterfalls also developed within pseudokarstic features, but are less frequent. The origin of the Presidente Figueiredo waterfalls probably goes back to the Neogene, when the region was submitted to laterization processes associated with a humid climate and a dense rainforest. These conditions favored the development of caves in quartzarenites of the Nhamundá Formation. During the Quaternary, the region was subjected to NE-trending normal faulting which displaced laterite layers, rivers and streams giving rise to waterfalls. These climatic and tectonic phenomena promoted intense relief dissection, as indicated by fault escarpment retreat and cave dismantlement, responsible for the present-day morphologic configuration.As cachoeiras da região de Presidente Figueiredo constituem um dos mais fascinantes cenários naturais do nordeste do Estado do Amazonas, norte do Brasil. As quedas, geralmente com menos de 10m de altura, são desenvolvidas em rochas siliciclásticas das formações Nhamundá (Siluriano inferior e Manacapuru (Siluriano superior-Devoniano inferior. Os estudos morfológico e estrutural dessas feições indicam que a maioria dessas quedas de água originaram-se por neotectônica quaternária e encontram-se instaladas em escarpas de falhas normais NE-SW.

  10. New sedimentological and palynological data from surface Miocene strata in the central Amazonas Basin area

    Directory of Open Access Journals (Sweden)

    Emílio Alberto Amaral Soares

    Full Text Available ABSTRACT The scarcity of stratigraphic data has hindered the demarcation of the outcropping area of Miocene deposits of the Amazon Basin, represented informally by the Novo Remanso Formation. Moreover, this unit is characterized by a sparse and irregular geographic distribution due to its sedimentological features and rare fossil content. Miocene deposits cropping out in central Amazonas Basin area were described in sedimentological terms and analyzed palynologically. All analyses were undertaken in samples collected at the Uatumã River banks (Itapiranga and São Sebastião do Uatumã cities. Lithostratigraphic data shows that Novo Remanso Formation consists of sandstones, with subordinate conglomerates and pelites, characteristic of a meandering fluvial paleosystem, with fluvial channel, point bar, floodplain and crevasse splay facies. The palynoflora retrieved from five samples consists exclusively of continental-origin palynomorphs dominated by angiosperms species. Trilete spores are well represented, while gymnosperms pollen grains are minor components. The presence of Psilastephanoporites tesseroporus, Syncolporites poricostatus, Jandufouria seamrogiformis and Polypodiaceoisporites potoniei ensure these deposits fits into the Grimsdalea magnaclavata palynozone (Regali et al. 1974a, b, and the Grimsdalea magnaclavata/Crassoretitriletes vanraadshooveni palynozones of Jaramillo et al. (2011 considered Middle Miocene age. This age is confirmed by the zonation of Jaramillo et al. (2011, based on the LADs of Bombacacidites baumfalki (11.57Ma and Crototricolpites annemariae (12.91Ma; and the FAD of Psilastephanoporites tesseroporus (14.00Ma. With these new data presented herein, it is possible to assume that the Miocene strata represented by the Novo Remanso Formation covers a larger area in the basin than previously considered, and that it may be extended for about 300 km until the Manacapuru village, indicating a Miocene subsidence phase.

    2017-09-01

    A 33-year-old female intact orange-winged Amazon parrot (Amazona amazonica) presented for a slowly growing mass over the right eye. A computed tomography scan performed with and without intravenous contrast revealed a heterogeneous mixed soft tissue and mineral-dense mass with a small area of non-contrast-enhancing fluid density located between the orbits at the caudal aspect of the nasal passages, with associated lysis of the right caudal nasal passage and the right frontal bone. Following euthanasia, the mass was found to consist of soft tissue between the right eye and nostril over the right frontal bone. Lysis of the underlying bone resulted in a bony defect leading into the infraorbital sinus along the dorsorostral aspect of the right eye. Histopathology revealed an unencapsulated, poorly demarcated, highly cellular neoplasm composed of islands and trabeculae of neoplastic cells embedded in abundant loose fibrovascular stroma which completely obliterated the cortical bone and sinuses of the rostral skull and infiltrated the surrounding muscle and soft tissue. Histologically, the tumor was consistent with a high-grade mucoepidermoid carcinoma, characterized by the presence of epidermoid, intermediate, and mucous-producing cell types. No evidence of metastasis was identified. The tissue of origin was suspected to be salivary or nasal mucous glands, but was difficult to confirm due to distortion of normal tissue architecture as a result of the tumor. Although mucoepidermoid carcinomas are a common salivary gland tumor in human medicine, they are not well recognized in avian species, and no specific case reports exist describing this pathology in an Amazon parrot. Despite the lack of distinct salivary glands in most avian species, mucoepidermoid carcinomas can occur, can cause significant clinical disease, and should be included as a differential diagnosis for avian patients presenting with similar lesions.

Tramadol hydrochloride was administered to each parrot at a dosage of 30 mg/kg, PO, every 12 hours for 5 days. Blood samples were collected just prior to dose 2 on the first day of administration (day 1) and 5 minutes before and 10, 20, 30, 60, 90, 180, 360, and 720 minutes after the morning dose was given on day 5. Plasma was harvested from blood samples and analyzed by high-performance liquid chromatography. Degree of sedation was evaluated in each parrot throughout the study. No changes in the parrots' behavior were observed. Twelve hours after the first dose was administered, mean ± SD concentrations of tramadol and its only active metabolite M1 (O-desmethyltramadol) were 53 ± 57 ng/mL and 6 ± 6 ng/mL, respectively. At steady state following 4.5 days of twice-daily administration, the mean half-lives for plasma tramadol and M1 concentrations were 2.92 ± 0.78 hours and 2.14 ± 0.07 hours, respectively. On day 5 of tramadol administration, plasma concentrations remained in the therapeutic range for approximately 6 hours. Other tramadol metabolites (M2, M4, and M5) were also present. On the basis of these results and modeling of the data, tramadol at a dosage of 30 mg/kg, PO, will likely need to be administered every 6 to 8 hours to maintain therapeutic plasma concentrations in Hispaniolan Amazon parrots.

    To evaluate the antinociceptive effects and duration of action of nalbuphine HCl administered IM on thermal thresholds in Hispaniolan Amazon parrots (Amazona ventralis). 14 healthy adult Hispaniolan Amazon parrots of unknown sex. 3 doses of nalbuphine (12.5, 25, and 50 mg/kg, IM) and saline (0.9% NaCl) solution (control treatment) were evaluated in a blinded complete crossover experimental design by use of foot withdrawal threshold to a noxious thermal stimulus. Baseline data on thermal threshold were generated 1 hour before administration of nalbuphine or saline solution; thermal threshold measurements were obtained 0.5, 1.5, 3, and 6 hours after administration. Nalbuphine administered IM at 12.5 mg/kg significantly increased the thermal threshold (mean change, 2.4°C), compared with results for the control treatment, and significantly changed thermal threshold for up to 3 hours, compared with baseline results (mean change, 2.6° to 3.8°C). Higher doses of nalbuphine did not significantly change thermal thresholds, compared with results for the control treatment, but had a significant effect, compared with baseline results, for up to 3 and 1.5 hours after administration, respectively. Nalbuphine administered IM at 12.5 mg/kg significantly increased the foot withdrawal threshold to a thermal noxious stimulus in Hispaniolan Amazon parrots. Higher doses of nalbuphine did not result in significantly increased thermal thresholds or a longer duration of action and would be expected to result in less analgesic effect than lower doses. Further studies are needed to fully evaluate the analgesic effects of nalbuphine in psittacine species.

    Pimobendan is a phosphodiesterase (PDE) inhibitor and calcium sensitizer with inotropic, lusitropic, and rasodilator properties used in the treatment of congestive heart failure. The mechanism of action is by inhibition of PDE III and V and by increasing intracellular calcium sensitivity in the cardiac myocardium. Pharmacokinetic and pharmacodynamic studies have been published in humans, dogs, and cats, but there are no studies in avian species. Pimobendan has been used in birds at the empirical dosage of 0.25 mg/kg q12h. To determine the pharmacokinetic parameters of pimobendan in Hispaniolan Amazon parrots (Amazona ventralis), 3 pilot studies with 2 birds, each receiving 1, 3, and 10 mg/kg PO, provided the basis for the pivotal trials with 6 birds, each receiving 10 mg/kg PO using 2 different suspensions. Blood samples were obtained at 0, 0.5, 1, 1.5, 2, 3, 4, 8, 12, and 18 hours after drug administration. Plasma concentrations were determined by liquid chromatography-tandem mass spectrometry (HPLC/MS) by use of electrospray ionization. Because of the erratic and low concentrations of pimobendan, pharmacokinetic parameters were calculated using naive averaged analysis. Plasma concentrations after commercial pimobendan tablet suspension at 10 mg/kg reached a Cmax of 8.26 ng/mL at 3 hours with a terminal half-life of 2.1 hours, while concentrations after the bulk chemical suspension reached a Cmax of 1.28 ng/mL at 12 hours and had a terminal half-life of 2.3 hours. Further studies evaluating the effect of oral pimobendan in parrots are needed.

    Ultrasonographic evaluation of the eye is a relatively recent addition to routine ophthalmic diagnostics in small animal ophthalmology. Some parameters for ophthalmic biometry have been established. There are few studies in clinical avian ophthalmology that describe ultrasound images of eye in some nocturnal avian species and in other birds that do not belong to the Brazilian fauna, but the psittacine family is not represented. The purpose of this study was to describe the following measurements: the distances between cornea and anterior lens capsule (D1) between the anterior and posterior lens capsule (D2), between posterior lens capsule and optic papilla (D3) and the axial length. Sixty four transpalpebral ocular ultrasound examinations were performed on 32 Blue fronted Amazon parrots (Amazona aestiva) with no history of previous ophthalmic disease. The measurements were taken in sagital planes using a 10 MHz linear probe without a standoff pad. The mean values for the left eye were; D1 0.17 ± 0.03 cm, D2 0.35 ± 0.02 cm, D3 0.73 ± 0.04 cm and the axial length 1.26 ± 0.06 cm. In the right eye D1 0.17 ± 0.02 cm, D2 0.34 ± 0.02 cm, D3 0.74 ± 0.03 cm and the axial length 1.25 ± 0.05 cm. No significant statistical difference was observed among the birds or between the left and right eye. The description of these parameters will allow the veterinary practitioner to evaluate the structural changes that specific diseases may cause in these animals.

    To evaluate antinociceptive effects on thermal thresholds after oral administration of tramadol hydrochloride to Hispaniolan Amazon parrots (Amazona ventralis). Animals-15 healthy adult Hispaniolan Amazon parrots. 2 crossover experiments were conducted. In the first experiment, 15 parrots received 3 treatments (tramadol at 2 doses [10 and 20 mg/kg] and a control suspension) administered orally. In the second experiment, 11 parrots received 2 treatments (tramadol hydrochloride [30 mg/kg] and a control suspension) administered orally. Baseline thermal foot withdrawal threshold was measured 1 hour before drug or control suspension administration; thermal foot withdrawal threshold was measured after administration at 0.5, 1.5, 3, and 6 hours (both experiments) and also at 9 hours (second experiment only). For the first experiment, there were no overall effects of treatment, hour, period, or any interactions. For the second experiment, there was an overall effect of treatment, with a significant difference between tramadol hydrochloride and control suspension (mean change from baseline, 2.00° and -0.09°C, respectively). There also was a significant change from baseline for tramadol hydrochloride at 0.5, 1.5, and 6 hours after administration but not at 3 or 9 hours after administration. Tramadol at a dose of 30 mg/kg, PO, induced thermal antinociception in Hispaniolan Amazon parrots. This dose was necessary for induction of significant and sustained analgesic effects, with duration of action up to 6 hours. Further studies with other types of noxious stimulation, dosages, and intervals are needed to fully evaluate the analgesic effects of tramadol hydrochloride in psittacines.

    To assess the effects of dopamine and dobutamine on the blood pressure of isoflurane-anesthetized Hispaniolan Amazon parrots (Amazona ventralis). 8 Hispaniolan Amazon parrots. A randomized crossover study was conducted. Each bird was anesthetized (anesthesia maintained by administration of 2.5% isoflurane in oxygen) and received 3 doses of each drug during a treatment period of 20 min/dose. Treatments were constant rate infusions (CRIs) of dobutamine (5, 10, and 15 μg/kg/min) and dopamine (5, 7, and 10 μg/kg/min). Direct systolic, diastolic, and mean arterial pressure measurements, heart rate, esophageal temperature, and end-tidal partial pressure of CO(2) were recorded throughout the treatment periods. Mean ± SD of the systolic, mean, and diastolic arterial blood pressures at time 0 (initiation of a CRI) were 132.9 ± 22.1 mm Hg, 116.9 ± 20.5 mm Hg, and 101.9 ± 22.0 mm Hg, respectively. Dopamine resulted in significantly higher values than did dobutamine for the measured variables, except for end-tidal partial pressure of CO(2). Post hoc multiple comparisons revealed that the changes in arterial blood pressure were significantly different 4 to 7 minutes after initiation of a CRI. Overall, dopamine at rates of 7 and 10 μg/kg/min and dobutamine at a rate of 15 μg/kg/min caused the greatest increases in arterial blood pressure. Dobutamine CRI at 5, 10, and 15 μg/kg/min and dopamine CRI at 5, 7, and 10 μg/kg/min may be useful in correcting severe hypotension in Hispaniolan Amazon parrots caused by anesthesia maintained with 2.5% isoflurane.

    The availability of digital elevation models produced by the SRTM (Shuttle Radar Topographic Mission) opened new possibilities for studies of geological remote sensing in the Amazonia, since these models enhance subtle details of the terrain and drainage system, usually masked in conventional orbital images. Using as a case study an area located in the Amazonas sedimentary basin, this article discusses an approach to use these data as an aid to oil exploration in that region. The analysis of the drainage network automatically extracted from that product, combined with altitude information provided by the digital elevation model, revealed a number of drainage anomalies, which may indicate surface expression of buried geological features. One of these drainage anomalies is located exactly within the limits of the Azulao Gas Field, and may correspond to the surface expression of the hydrocarbon trapping structures in that area. The methodological approach discussed in this study can be replicated elsewhere in the Amazonas and Solimoes sedimentary basins, which together comprise about 1,000,000 km{sup 2} covered by rainforest.

    In this work we document and analyze the hydrological annual cycles characterized by a rapid transition between low and high flows in the Amazonas River (Peruvian Amazon) and we show how these events, which may impact vulnerable riverside residents, are related to regional climate variability. Our analysis is based on comprehensive discharge, rainfall and average suspended sediment data sets. Particular attention is paid to the 2010-11 hydrological year, when an unprecedented abrupt transition from the extreme September 2010 drought (8300 m3 s-1) to one of the four highest discharges in April 2011 (49 500 m3 s-1) was recorded at Tamshiyacu (Amazonas River). This unusual transition is also observed in average suspended sediments. Years with a rapid increase in discharge are characterized by negative sea surface temperature anomalies in the central equatorial Pacific during austral summer, corresponding to a La Niña-like mode. It originates a geopotential height wave train over the subtropical South Pacific and southeastern South America, with a negative anomaly along the southern Amazon and the southeastern South Atlantic convergence zone region. As a consequence, the monsoon flux is retained over the Amazon and a strong convergence of humidity occurs in the Peruvian Amazon basin, favoring high rainfall and discharge. These features are also reported during the 2010-11 austral summer, when an intense La Niña event characterized the equatorial Pacific.

    Full Text Available ABSTRACT Introduction: Human T-lymphotropic virus type 1 and 2 (HTLV-1/2 is endemic in Brazil, but few studies have investigated the seroprevalence of HTLV and its subtypes among blood donors in the capital city Manaus, Amazonas State, Brazil. Aim: To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus. Materials and Methods: Blood donors (2001-2003 were screened for HTLV-1/2 antibodies by ELISA. Positive results were confirmed and subtyped by Western blot assays. Prevalence rates were calculated and compared with demographic data. Results: Among the 87,402 individuals screened, 116 (0.13% were seropositive for HTLV-1/2. A second sample (76/116 was collected and retested by HTLV-1/2 ELISA, of which only 41/76 were positive. Western blot confirmed HTLV infection in 24/41 retested blood donors [HTLV-1 (n=16, HTLV-2 (n=5 and HTLV-untypable (n=3]. Discussion: HTLV-1 and HTLV-2 are prevalent among blood donors in Manaus. However, additional studies are needed to comprehend the epidemiology of HTLV-1/2 in Amazonas not only to understand the pathophysiology of the disease providing adequate medical assistance, but also to reduce or block virus transmission.

    The Amazonas Territory of Venezuela is a large area of Precambrian basement rocks overlain in some locales by the supracrustal sedimentary and volcanic rocks of the Roraima Formation. The basement rocks are medium to high grade gneisses with both igneous and sedimentary protoliths, plutonic rocks ranging in composition from granite to tonalite, and meta-volcanic rocks. Rb-Sr whole rock, and U-Pb isotopic analyses of zircons indicate a period of medium to high grade metamorphism and intrusion from 1860 to 1760 Ma. Post-tectonic plutonic activity continued to 1550 Ma. The volcanic rocks of the Roraima Formation in Venezuela give an age of 1746 Ma comparable to volcanic rocks of the Roraima Formation in other parts of the Guiana Shield. The ages and distribution of the basement rocks suggest the presence of a tectonic zone, approximately coincident with the Venezuelan-Colombian border, representing an active orogenic boundary between distinct tectonic provinces. The rocks to the northeast of this zone are part of the Trans-Amazonian of the Guiana Shield, while to the southwest and in adjacent Brazil and Colombia, new younger continental crust has been developed and cratonized. We suggest a model of collision and subduction followed by a chan0140n tectonic style to extensional-vertical to produce the basement rocks of the western Guiana Shield in the Amazonas Territory.

    Full Text Available Carrion’s disease (CD, is a human bartonellosis, that is, endemic in the Andes of Peru, Ecuador, and Colombia. Bartonella bacilliformis, a native hemotrophic bacteria, is the causative agent of CD, and the interaction with the host could have produced changes in the gene frequencies of erythrocyte antigens. The goal here is to investigate the relationship between allele frequencies of blood group systems MNS, Diego, and Duffy and the clinical phases of CD, within a genetic context. In this associative and analytical study, 76 individuals from Bagua Grande, the province of Utcubamba, and the department of Amazonas in Peru, were enrolled. Forty of them resided in Tomocho-Collicate-Vista Hermosa area (high prevalence of cases in chronic phase, verrucous, or eruptive phase, without previous acute phase. Thirty-six individuals were from the area of Miraflores (high prevalence of cases in acute phase only and were evaluated for blood group systems MNS, Diego, and Duffy. This study constitutes one of the first attempts at evaluating the genetic factors and clinical phases of CD. No significant statistical differences (P>0.05 between allele frequencies of blood groups MNS, Diego, and Duffy and the prevalence of chronic and acute phases were detected in the two areas of Amazonas, Peru.

    The Neotropical psittacine species Amazona aestiva, commonly known as the blue-fronted Amazon, is one of the most common and best-known psittacine birds kept as a pet worldwide. However, very little is known about the diseases or parasites of these birds. In this study, we describe a new species, Eimeria aestivae, associated with these parrots. The new species is characterized by: ovoid smooth oocysts (n  =  60), 36.8 (33.2-41.5) × 23.7 (21.7-25.7) µm, length/width ratio  =  1.55; polar granule present; ellipsoidal sporocysts (n  =  25), 19.8 (17.5-21.6) × 9.3 (8.3-9.9) µm; Stieda, sub-Stieda body, and sporocyst residuum present. Sporozoites (n  =  20), 2 per sporocyst, elongate and curved, 17.6 (15.8-19.2) × 3.8 (3.2-4.8) µm; each with 2 refractile bodies. The oocysts of the other 2 eimerian species described for Amazona are larger than those of the presented species, but they all seem to be closely related because of some similarities among them.

En la medida en que el currículum organiza el conocimiento en distintas dimensiones, como por ejemplo las actitudes, es que el afecto consolida la neutralidad requerida para mantener órdenes sociales y culturales; particularmente cuando nos referimos a categorías de raza, etnia, clase social, género y sexualidad. Por lo tanto, el objetivo es mostrar como el afecto es usado a través del currículum escolar para promover formas neutrales de producir sujetos escolares. Más que dar respuestas, el esfuerzo de este artículo está en producir problemáticas acerca de cómo se ha sofisticado la regulación de los sujetos a través del currículum.

    Origen and development of the highly diverse Amazon tropical forest has mostly been inferred from continental sites. However, sediment records in the marine Foz do Amazonas Basin can provide important information to better understand the influence of the Andes uplift and climate change on its plant biomes evolution since the Neogene. Sediment analyses of samples from BP-Petrobras well 1 and 2, drilled in the Amazon Fan, allowed to infer the onset of the transcontinental Amazon river and the fan phase during the middle to late Miocene (c. 10.5 Ma). As part of the CLIMAMAZON research programme we performed pollen analysis on the 10.5 to 0.4 Ma time interval. 76 ditch cutting samples of the upper 4165 m sediments of well 2 permitted us to infer changes in floral composition in the Amazon Basin. The palynological spectra across this interval (nannofossil based age model) include pollen, fern spores, dinocysts and foram lignings. When possible pollen and fern spores were grouped in four vegetation types: estuarine, tropical, mountain forest and high mountain open treeless vegetation. Pollen is generally corroded and reflects the effects of sediment transportation while reworked material is also common. Good pollen producers such as Poaceae, Asteraceae and Cyperaceae are common and reflect indistinctive vegetation types particularly those associated to riverine systems. Rhizophora/Zonocostites spp. indicate "close-distance" mangrove development. Tropical forest biomes are represented by pollen that resemble Moraceae-Urticaceae, Melastomataceae-Combretaceae, Sapotaceae, Alchornea, Euphorbiaceae, Rubiaceae, Bignoniaceae, Mauritia and Arecaceae. Myrica, and particularly sporadic occurrences of fossil fern spores like Lophosoria, and Cyathea suggest the development of a moist Andean forest in areas above 1000 m. First indicators of high altitudes appear in the last part of late Miocene with taxa associated to current Valeriana and particularly Polylepis, a neotropical taxon

    To compare palpation-guided with ultrasound-guided brachial plexus blockade in Hispaniolan Amazon parrots. Prospective randomized experimental trial. Eighteen adult Hispaniolan Amazon parrots (Amazona ventralis) weighing 252-295 g. After induction of anesthesia with isoflurane, parrots received an injection of lidocaine (2 mg kg(-1)) in a total volume of 0.3 mL at the axillary region. The birds were randomly assigned to equal groups using either palpation or ultrasound as a guide for the brachial plexus block. Nerve evoked muscle potentials (NEMP) were used to monitor effectiveness of brachial plexus block. The palpation-guided group received the local anesthetic at the space between the pectoral muscle, triceps, and supracoracoideus aticimus muscle, at the insertion of the tendons of the caudal coracobrachial muscle, and the caudal scapulohumeral muscle. For the ultrasound-guided group, the brachial plexus and the adjacent vessels were located with B-mode ultrasonography using a 7-15 MHz linear probe. After location, an 8-5 MHz convex transducer was used to guide injections. General anesthesia was discontinued 20 minutes after lidocaine injection and the birds recovered in a padded cage. Both techniques decreased the amplitude of NEMP. Statistically significant differences in NEMP amplitudes, were observed within the ultrasound-guided group at 5, 10, 15, and 20 minutes after injection and within the palpation-guided group at 10, 15, and 20 minutes after injection. There was no statistically significant difference between the two groups. No effect on motor function, muscle relaxation or wing droop was observed after brachial plexus block. The onset of the brachial plexus block tended to be faster when ultrasonography was used. Brachial plexus injection can be performed in Hispaniolan Amazon parrots and nerve evoked muscle potentials were useful to monitor the effects on nerve conduction in this avian species. Neither technique produced an effective block at the

    Previous studies have validated the clinical use of opioids with kaap-receptor affinities for pain management in birds. Butorphanol, a kappa opioid receptor agonist and a mu opioid receptor antagonist, is currently considered by many clinicians to be the opioid of choice for this use. However, despite studies reporting the analgesic properties of butorphanol in psittacine birds, dosing intervals have not been established for any psittacine species. The goals of this study in the Hispaniolan Amazon parrot (Amazona ventralis) were to evaluate the pharmacokinetics of butorphanol tartrate after intravenous (IV), intramuscular (IM), and oral (PO) administration and to determine the bioavailability of butorphanol tartrate after oral administration. Twelve Hispaniolan Amazon parrots were used in the study, with a complete-crossover experimental design and a 3-month period separating each part of the study. The birds were randomly assigned to 3 groups (n = 4) for each stage. Butorphanol tartrate was administered once at a dose of 5 mg/kg in the basilic vein or pectoral muscles or as an oral solution delivered via feeding tube into the crop for the IV, IM, and PO studies, respectively. After butorphanol administration, blood samples were collected at 1, 5, 15, 30, 60, 90, 120, 180, and 240 minutes for the IV and IM studies and at 5, 15, 30, 60, 90, 120, 180, 240, and 300 minutes for the PO study. Because of the size limitation of the birds, naive pooling of datum points was used to generate a mean plasma butorphanol concentration at each time point. For each study, birds in each group (n = 4) were bled 3 times after dosing. Plasma butorphanol concentrations were determined by high-performance liquid chromatography/tandem mass spectrometry, and pharmacokinetic parameters were calculated. Butorphanol tartrate was found to have high bioavailability and rapid elimination following IM administration. In contrast, oral administration resulted in low bioavailability (Amazon

    Colour-flow and pulsed-wave spectral Doppler echocardiography was performed on 6 healthy, adult Hispaniolan amazon parrots (Amazona ventralis) and 6 blue-fronted amazon parrots (Amazona a. aestiva) to establish normal reference values. Birds were anesthetized with isoflurane in oxygen and placed in dorsal recumbency. An electrocardiogram was recorded continuously and birds were imaged with a micro-phased-array scanner with a frequency of 7.0 MHz. After assessment of cardiac function in 2-D-echocardiography, blood flow across the left and the right atrioventricular valve and across the aortic valve was determined using color-flow and pulsed-wave spectral Doppler echocardiography. Diastolic inflow (mean value +/- standard deviation) into the left ventricle was 0.17 +/- 0.02 m/s (Hispaniolan amazons) and 0.18 +/- 0.03 m/s (Blue fronted amazons). Diastolic inflow into the right ventricle was 0.22 +/- 0.05 m/s (Hispaniolan amazons) and 0.22 +/- 0.04 m/s (Blue fronted amazons). Velocity across the aortic valve was 0.84 +/- 0.07 m/s (Hispaniolan amazons) and 0.83 +/- 0.08 m/s (Blue fronted amazons). Systolic pulmonary flow could not be detected in any of the birds in this study. No significant differences were evident between the two species examined. Results of this study indicate that Doppler echocardiography is a promising technique to determine blood flow in the avian heart. Further studies in other avian species are needed to establish reference values for assessment of cardiac function in diseased birds.

    This article brings to discuss the policy of universalization of the supply of electrical energy 'Luz para todos' showing the significance of this proposal of the government, in a short time, bring electricity to more than 10 million people who still live in the darkness. It features the efficiency of this action of the government from the reality experienced in the context Amazon, which show a framework for various characteristics and natural, cultural and focused on the issue geospatial. This involves understanding the multitude of climates and geographical characteristics, cultural and social constitute major obstacles for the implementation of policies homogeneous, demonstrating that the potential for development of each region has different dynamics, which should influence in the formulation of policies. While electricity is essential for the economic progress of a country, the expansion of its services to society must be viewed with great discretion, in order to prevent the exploitation and consumption exacerbated of natural resources and waste of energy. With this reading, the work he proposes to show the inconsistencies of the program in the state of Amazonas, on presentation of data from the Companhia Energetica do Amazonas (CEAM), showing thus obstacles to the achievement of the goals outlined in the State. Considering the environmental importance that the Amazon represents for Brazil and for the world, emerges is the need for a differentiated look for the region, taking into account their unique reality. It is believed that is the acceptance of their characteristics that we can really promote a development that is sustainable for the Amazon. (author)

    The aim of the study was to characterize atherosclerotic changes in African grey parrots (Psittacus erithacus) and Amazon parrots (Amazona spp.) by histochemical and immunohistochemical methods. Samples of the aorta ascendens and trunci brachiocephalici from 62 African grey parrots and 35 Amazon parrots were stained by hematoxylin and eosin and Elastica van Gieson for grading of atherosclerosis in these birds. Four different stages were differentiated. The incidence of atherosclerosis in the examined parrots was 91.9% in African grey parrots and 91.4% in Amazon parrots. To evaluate the pathogenesis in birds, immunohistochemical methods were performed to demonstrate lymphocytes, macrophages, smooth muscle cells, and chondroitin sulfate. According to the missing lymphocytes and macrophages and the absence of invasion and proliferation of smooth muscle cells in each atherosclerotic stage, "response-to-injury hypothesis" seems inapplicable in parrots. Additionally, we found alterations of vitally important organs (heart, lungs) significantly correlated with atherosclerosis of the aorta ascendens.

Trata-se de estudo qualitativo, prospectivo, baseado em dados coletados por meio de entrevistas semiestruturadas com usuários que receberam medicamentos via mandado judicial. A judicialização na saúde mostrou-se um fator agregador ao reconhecimento dos direitos e da cidadania pelos usuários que, na sua trajetória de vida, acabaram adquirindo um grande aprendizado sobre formas de enfrentar a falta de acesso aos medicamentos. Conclui-se que a relação entre o sujeito e o Estado permanece desigual, e o direito à saúde se deu na dimensão individual e restritiva, desconsiderando a dimensão coletiva e a concepção de cidadania.

    Full Text Available Abstract Background Amazona vittata is a critically endangered Puerto Rican endemic bird, the only surviving native parrot species in the United States territory, and the first parrot in the large Neotropical genus Amazona, to be studied on a genomic scale. Findings In a unique community-based funded project, DNA from an A. vittata female was sequenced using a HiSeq Illumina platform, resulting in a total of ~42.5 billion nucleotide bases. This provided approximately 26.89x average coverage depth at the completion of this funding phase. Filtering followed by assembly resulted in 259,423 contigs (N50 = 6,983 bp, longest = 75,003 bp, which was further scaffolded into 148,255 fragments (N50 = 19,470, longest = 206,462 bp. This provided ~76% coverage of the genome based on an estimated size of 1.58 Gb. The assembled scaffolds allowed basic genomic annotation and comparative analyses with other available avian whole-genome sequences. Conclusions The current data represents the first genomic information from and work carried out with a unique source of funding. This analysis further provides a means for directed training of young researchers in genetic and bioinformatics analyses and will facilitate progress towards a full assembly and annotation of the Puerto Rican parrot genome. It also adds extensive genomic data to a new branch of the avian tree, making it useful for comparative analyses with other avian species. Ultimately, the knowledge acquired from these data will contribute to an improved understanding of the overall population health of this species and aid in ongoing and future conservation efforts.

    Hypercholesterolemia is common in psittacines, and Amazon parrots ( Amazona spp.) are particularly susceptible. Associations have been demonstrated between naturally occurring and experimentally induced hypercholesterolemia and atherosclerosis in psittacines. Daily exercise improves lipid metabolism in humans and other mammals, as well as pigeons and chickens, under varying experimental conditions. Hispaniolan Amazon parrots ( Amazona ventralis ) with naturally occurring hypercholesterolemia (343-576 mg/dl) were divided into two groups. An exercised group (n = 8) was housed as a flock and exercised daily with 30 min of aviary flight and 30 min walking on a rotating perch. A sedentary control group (n = 4) was housed in individual cages with no exercise regime. A plasma lipid panel, including total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and triglycerides, was validated for this species. Body weight, chest girth, and the lipid panel were measured at 0, 61, and 105 days. Hematology and plasma biochemistry were measured at 0 and 105 days. Weight and girth were significantly lower in exercised than sedentary parrots at 61 and 105 days. HDL-C concentrations were significantly higher in exercised parrots at 61 days but returned to near baseline by 105 days. There were no significant changes in hematology, biochemistry, or other lipid panel parameters. Results were similar to studies in humans and animal models, in which increased HDL-C was the most consistent effect of exercise on circulating lipid and lipoprotein parameters. The return toward baseline HDL-C may have resulted from decreased participation in aviary flight. Additional investigation will be required to determine the amount of exercise and change in circulating lipid-related parameters necessary to improve long-term wellness in psittacine species predisposed to hypercholesterolemia.

    Full Text Available In Brazil, more than 99% of malaria cases are reported in the Amazon, and the State of Amazonas accounts for 40% of this total. However, the accumulated experience and challenges in controlling malaria in this region in recent decades have not been reported. Throughout the first economic cycle during the rubber boom (1879 to 1912, malaria was recorded in the entire state, with the highest incidence in the villages near the Madeira River in the Southern part of the State of Amazonas. In the 1970s, during the second economic development cycle, the economy turned to the industrial sector and demanded a large labor force, resulting in a large migratory influx to the capital Manaus. Over time, a gradual increase in malaria transmission was observed in peri-urban areas. In the 1990s, the stimulation of agroforestry, particularly fish farming, led to the formation of permanent Anopheline breeding sites and increased malaria in settlements. The estimation of environmental impacts and the planning of measures to mitigate them, as seen in the construction of the Coari-Manaus gas pipeline, proved effective. Considering the changes occurred since the Amsterdam Conference in 1992, disease control has been based on early diagnosis and treatment, but the development of parasites that are resistant to major antimalarial drugs in Brazilian Amazon has posed a new challenge. Despite the decreased lethality and the gradual decrease in the number of malaria cases, disease elimination, which should be associated with government programs for economic development in the region, continues to be a challenge.

The present study reports the molecular and epidemiological characterization of 31 HIV-1 isolates from blood donors from the State of Amazonas who donated blood between April 2006 and March 2007. Serum/plasma samples from all donors were screened for HIV antibodies by ELISA and the results confirmed by Western blot analysis. Genomic DNA was extracted from the buffy coat using the Super Quik-Gene-DNA Isolation kit. Nested PCR was performed on the env, gag, and pol regions of HIV-1 using the Gene Amp PCR System 9700. Sequencing reactions were performed using the inner PCR primers and the DYEnamic™ ET Dye Terminator Kit, and phylogenetic analysis was performed using the gag, pol, and env gene sequences. We collected samples from 31 blood donors who tested positive for HIV-1 in confirmatory experiments. The male:female ratio of blood donors was 3.4:1, and the mean age was 32.4 years (range: 19 to 61 years). Phylogenetic analysis showed that subtype B is the most prevalent among Northern Brazilian HIV-1-seropositive blood donors. One HIV-1 subtype C and one circulating recombinant form (CRF-BF) of HIV-1 were identified in the State of Amazonas. This is the first study showing the occurrence of a possible “homogenous” subtype C in this region of Brazil. This finding could contribute to a better characterization of the HIV-1 strains that circulate in the country.

    The nesting requirements of the Yellow-headed Parrot (Amazona oratrix) are poorly understood, despite their broad historical distribution, high demand for pet trade and current endangered status. Information concerning their nesting requirements is required in order to design specific restoration and conser- vation actions. To assess this, we studied their nesting ecology in the Central Pacific, Michoacan, Mexico during a ten year period. The analyzed variables ranged from local scale nest site characteristics such as nesting tree species, dimensions, geographic positions, diet and nesting forest patches structure, to large scale features such as vegetation use and climatic variables associated to the nesting tree distributions by an ecological niche model using Maxent. We also evaluated the parrot tolerance to land management regimes, and compared the Pacific nest trees with 18 nest trees recorded in an intensively managed private ranch in Tamaulipas, Gulf of Mexico. Parrots nested in tall trees with canopy level cavities in 92 nest-trees recorded from 11 tree species. The 72.8% of nesting occurred in trees of Astronium graveolens, and Enterolobium cyclocarpum which qualified as key- stone trees. The forests where the parrots nested, presented a maximum of 54 tree species, 50% of which were identified as food source; besides, these areas also had a high abundance of trees used as food supply. The lowest number of tree species and trees to forage occurred in an active cattle ranch, whereas the highest species rich- ness was observed in areas with natural recovery. The nesting cavity entrance height from above ground of the Pacific nesting trees resulted higher than those found in the Gulf of Mexico. We hypothesize that the differences may be attributed to Parrot behavioral differences adapting to differential poaching pressure and cavity avail- ability. Nesting trees were found in six vegetation types; however the parrots preferred conserved and riparian semi

    To determine the pharmacokinetics of piperacillin/tazobactam in Hispaniolan Amazon parrots ( Amazona ventralis ), 8 healthy adult parrots of both sexes were used in a 2-part study. In a pilot study, piperacillin (87 mg/kg) in combination with tazobactam (11 mg/kg) was administered intramuscularly (IM) to 2 birds, and blood samples were obtained at 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 10 hours after administration. Based on the results obtained, a main study was done in which piperacillin/tazobactam was administered at 2 different doses. In 3 birds, the initial dose of piperacillin (87 mg/kg)/tazobactam (11 mg/kg) IM was administered, and in 3 birds, the dose was doubled to piperacillin (174 mg/kg)/tazobactam (22 mg/kg) IM. In all 6 birds, blood samples were obtained at 0, 5, 15, and 30 minutes and at 1, 1.5, 2, 2.5, 3, and 4 hours after administration. Quantification of plasma piperacillin and tazobactam concentrations was determined by validated liquid chromatography-mass spectrometry assay. Pharmacokinetic parameters were determined by noncompartmental analysis. After intramuscular administration, the mean ± standard error values of T 1/2 (h) was 0.52 ± 0.05 and 0.32 ± 0.07, T max (h) was 0.28 ± 0.09 and 0.25 ± 0.10, C max (μg/mL) was 86.34 ± 20.62 and 9.03 ± 2.88, and C max /dose was 0.99 ± 0.24 and 0.83 ± 0.26 for piperacillin (87 mg/kg) and tazobactam (11 mg/kg), respectively. When the doses were doubled, the T 1/2 (h) was 0.65 ± 0.08 and 0.34 ± 0.02, T max (h) was 0.28 ± 0.12 and 0.14 ± 0.06, C max (μg/mL) was 233.0 ± 6.08 and 22.13 ± 2.35, and C max /dose was 1.34 ± 0.03 and 1.02 ± 0.11 for piperacillin and tazobactam, respectively. Results indicate that piperacillin is rapidly absorbed and reaches high initial concentrations; however, it is also rapidly eliminated in the Hispaniolan Amazon parrot, and tazobactam has similar pharmacokinetics as piperacillin. Administration of piperacillin at 87 mg/kg IM q3-4h is recommended for this species

    Full Text Available Atualmente a problemática relacionada aos resíduos sólidos vem ganhando destaque no tocante à necessidade de gerenciamento integrado e aos impactos ambientais e os problemas de saúde pública. Nesse sentido torna-se necessário a implementação de medidas de gestão para a extinção de lixões à céu aberto. Com base nesse contexto, objetivou-se avaliar os impactos ambientais causados pela prática inadequada de disposição de resíduos sólidos a céu aberto da cidade de Humaitá-AM. A metodologia utilizada baseou-se na realização de visitas de campo e aplicação do método de avaliação de impactos ambientais conhecido por “Índice de Impacto” e o índice da qualidade de aterros de resíduos (IQAR que permite avaliar as condições gerais da destinação final de resíduos sólidos urbanos, classificando os sistemas em condições adequadas, controladas e inadequadas. O lixão encontra-se em funcionamento inadequado, sem atender as regras de proteção ao meio ambiente, ocasionando assim inúmeros impactos ambientais, tais como: aumento dos processos erosivos do solo, compactação do solo, poluição do ar, poluição dos recursos hídricos, proliferação de micro e macrovetores, redução da biota do solo, stress da fauna local, poluição visual, contaminação dos catadores, entre outros. O valor do IQAR foi de 1,53, mostrando que as condições da área são inadequadas. Desta forma, é evidente a ação negativa do lixão devido à falta de manejo adequado, disposição final e políticas públicas voltadas ao gerenciamento dos resíduos sólidos gerados na cidade. Environmental impacts of landfill of the city of Humaitá, AmazonasAbstract: Currently the problems related to solid waste has been gaining attention on the need for integrated management and environmental impacts and public health problems.

    Full Text Available En el año 2006 se reconoció constitucionalmente la etnia diaguita como parte de los pueblos originarios de Chile. En paralelo, se generó un amplio debate que transitó desde lo político hasta lo académico, éste último haciendo referencia a los enfoques interpretativos de este fenómeno. De esta discusión surgieron diferentes terminologías para retratar este proceso, tales como la emergencia indígena y reetnificación. Sin embargo, a mi juicio, hubo un concepto que fue quedando atrás, al menos en el debate formal; el de etnogénesis. El caso diaguita, entre varios, permite, entre otras muchas posibilidades de reflexión, abrir la discusión teórica para la comprensión de los resurgimientos y reivindicaciones identitarias contemporáneas. El presente artículo se propone reflexionar en torno a la pertinencia del uso del concepto de etnogénesis en la actualidad, para la comprensión de los fenómenos recientes de emergencias de nuevas identidades indígenas, similares al proceso diaguita, a través de una trayectoria crítica del término.

    Full Text Available Objective: To analyze mortality rates and to describe the demographic and epidemiological characteristics of suicides recorded in the state of Amazonas. Methods: A descriptive and retrospective study has been carried out with emphasis on municipalities, which have shown, simultaneously, a high mortality rates and a high proportion of self-reported indigenous population, based on 2005 - 2009 data as provided by the Informatics Department of the Unified National Health System. Results: Among the general population of the state of Amazonas, the mortality rate, by suicide, of 4.2/100.000 inhabitants has been reported, similar to that of Manaus (4.6/100.000 inhabitants. In contrast, at Tabatinga (25.2/100.000 inhabitants, at São Gabriel da Cachoeira (27.6/100.000 inhabitants and at Santa Isabel do Rio Negro (36.4/100.000 inhabitants, municipalities, where the proportion of self-reported indigenous population is high, besides the taxes being notably higher, it was observed that most of the suicides has occurred among men; among young men aged between 15 - 24 years; at home; by hanging; during "weekend" and among the indigenous population. Discussion: Our findings have unveiled that suicide comes forth as a serious public health issue in some municipalities in the state of Amazonas, further indicating that the event occurs within very specific contexts, and that the dimension and the magnitude of the problem can be even more serious among populations or in territories exclusively inhabited by indigenous people.

Busca  caracterizar y problematizar las manifestaciones contemporáneas del feminismo en  las cantantes populares de funk  a través de una  indagación histórico hermenéutica. Para ello se realiza  una  contex- tualización histórica del funk  y una  revisión de las letras de algunos de los cantantes y las cantantes con  más  reconocimiento en  el género.  Así, se expone la propuesta de liberación sexual  y erotización del cuerpo femenino para confrontarla con la discusión desarrollada en blogs digitales sobre  la alienación de la mujer  que se supone conlleva el funk.  A partir de la confrontación con el feminismo de tercera ola se propone al funk como reafirmación de géne- ro, de clase baja y de etnia negra  que se consolida como  manifestación cultural feminista de las mujeres de favela. Ello, acompañado de un proceso de normalización e incorporación de este género musical a los valores  estándar, lo cual convierte el funk  en un discurso portador de postulados contradictorios.

Este município de população predominantemente indígena constitui uma importante noso-área da Amazônia para o problema da tuberculose, cuja magnitude se expressa por intermédio do coeficiente 2,4 vezes mais elevado que a média estadual e até quatro vezes mais que a média nacional. Análises estatísticas utilizadas para avaliar a tendência em relação à associação com a idade, o sexo e a forma clínica revelaram diferenças no comportamento da endemia, quando comparados os coeficientes de incidência entre os casos de procedência urbana e rural. As taxas padronizadas mostraram a população masculina com uma incidência mais elevada que a feminina nas duas áreas de residência. A faixa etária mais atingida foi acima de 50 anos, porém a proporção de menores de 15 anos se mostrou acima dos valores esperados na população geral do país, além de apresentar diferentes níveis de gravidade nas subáreas rurais estudadas. Os achados indicam que esta situação pode ser explicada pelas desigualdades, sobretudo, relativas à acessibilidade aos serviços de saúde que, contraditoriamente, parecem menos resolutivos na área urbana.This study describes the tuberculosis situation in São Gabriel da Cachoeira, Amazonas State, Brazil, from 1997 to 2002.

A avaliação do PSF não é algo simples, pois há vários fatores que contribuem para essa problemática. Outros estudos poderão revelar os fatores para sua classificação insatisfatória no Estado do Amazonas.This article focuses on the implementation of the Family Health Program (FHP in municipalities (counties in the State of Amazonas, Brazil, analyzing potential population coverage, evidence of change in the health care model, and impact (2004 and 2008. Implementation was classified as fair versus unsatisfactory. The findings showed an increase in the number of municipalities with the FHP implemented, as well as in the program's coverage (which nevertheless was less than 50% of the population. Concerning change in the health care model, no municipalities were observed with a high rate of change. As for impact, there was a decrease in low impact and an increase in high impact. The final classification did not show a statistically significant change from one year to the next, and unsatisfactory implementation prevailed

    Full Text Available INTRODUCTION: Estimate the prevalence of Mansonella ozzardi infection and calculate the parasitic infection rate (PIR in simuliid black flies in the municipality of Lábrea, State of Amazonas, Brazil. METHODS: Prevalence was measured using the thick blood smear method collected from the fingers and was related to age, sex and occupation. Simuliidae were collected with a suction apparatus, then stained with hematoxylin and dissected to verify the PIR. RESULTS: The average prevalence rate of M. ozzardi among the 694 individuals examined was 20.7%. Infection was higher in men (27.6% than in women (14.3% (p 58 (60.5%. The highest prevalence rates were observed in the retired (64%, followed by farm workers (47.1%. Infection by M. ozzardi was only identified in Cerqueirellum amazonicum (Simuliidae with a PIR of 0.6%. CONCLUSIONS: This study showed a high prevalence of M. ozzardi in the riverine communities of Lábrea due to the lack of policies regarding the treatment of microfilaremic individuals in the region and an abundance of competent vectors for M. ozzardi.

    Full Text Available This study investigated some epidemiological aspects of the Mansonella ozzardi in municipality of Coari, Amazonas. Clinical symptoms were correlated with the filarial infection and the parasitic infection rates (PIR were estimated in simuliid vectors. The general M. ozzardi human prevalence rate was 13.3% (231/1733, of which 10.2% (109/1069 were from the urban area and 18.4% (122/664 from the rural area. The prevalence rates were higher in men (14.5% urban and 19.7% rural than in women (6.7% urban and 17.2% rural and occurred in most age groups. The indices of microfilaremics were higher in people > 51 years old (26.9% urban and 61.5% rural. High prevalence rates were observed in retired people (27.1% urban area, housewives and farmer (41.6% and 25%, respectively, in rural area. The main clinical symptoms were joint pains and sensation of leg coldness. Only Cerqueirellum argentiscutum (Simuliidae transmits M. ozzardi in this municipality (PIR = 5.6% urban and 7.1% rural. M. ozzardi is a widely distributed parasitic disease in Coari. Thus, temporary residency in the region of people from other localities involved with the local gas exploitation might be a contributing factor in spreading the disease.

    Full Text Available The units of landscape in the Cocama and Ticuna agriculture, in the upper River Solimões, are characterized by productionarrangements and management of natural resources. This paper aims to characterize these agro-ecological based practices,the landscaped results and its regional applicability. The survey was conducted in Novo Paraíso, at Bom Intento Island,and in Nova Aliança, both located in the municipality of Benjamin Constant, state of Amazonas, Brazil. The social andeconomic organization of Ticuna and Cocama Peoples is founded on kinship and communal ownership of natural resources,including spaces for gathering. Family units, despite their weak linkages with the market and its rules, have in the logicof reciprocity the motivation for the production, transmission and management of resources and factors of production.The landscapes are reconstructed by agro-ecological production derived from ethno-knowledge and correspond to theinherent processes of management and conservation of flora and fauna. This process allows the existence of compleximbrications of constantly changing landscapes in which forms of production are recreated for sufficiency and sustainability.

    Full Text Available A violência contra crianças e adolescentes é um fenômeno frequente, mas pouco se conhece sobre o contexto em que ocorre e sobre suas consequências. O objetivo deste estudo é caracterizar esta violência no Interior do Estado do Amazonas. Foram analisados 193 registros do Relatório Txain sobre a Violência contra Crianças e Adolescentes. Como resultado, verificou-se que grande parte dos registros oficiais omitem informações. A agressão física é o tipo de violência mais relatado, e a maior parte das vítimas é constituída de adolescentes do sexo feminino de idades entre 12 e 15 anos. Os agressores são predominantemente desconhecidos das vítimas e são do sexo masculino. Em termos de consequências para a saúde, há referência a algumas lesões físicas, mas os dados são bastante omissos em relação à saúde mental. Estes dados sugerem a necessidade de integralização e aprimoramento dos sistemas de registro, informação e atendimento a vítimas fora das grandes cidades.

    J Ragusa-Netto

    Full Text Available Seed predation has major effects on the reproductive success of individuals, spatial patterns of populations, genetic variability, interspecific interactions and ultimately in the diversity of tree communities. At a Brazilian savanna, I evaluated the proportional crop loss of Eriotheca gracilipes due the Blue-Fronted Amazon (Amazona aestiva during a fruiting period. Also, I analyzed the relationship between proportional crop loss to Amazons and both fruit crop size and the distance from the nearest damaged conspecific. Trees produced from 1 to 109 fruits, so that Amazons foraged more often on trees bearing larger fruit crop size, while seldom visited less productive trees. Moreover, the relationship between fruit crop sizes and the number of depredated fruits was significant. However, when only damaged trees were assessed, I found a negative and significant relation between fruit crop size and proportional crop loss to Blue-Fronted Amazons. Taking into account this as a measure more directly related to the probability of seed survival, a negative density dependent effect emerged. Also, Amazons similarly damaged the fruit crops of either close or distant neighboring damaged trees. Hence, in spite of Blue-Fronted Amazons searched for E. gracilipes bearing large fruit crops, they were swamped due to the presence of more fruits than they could eat. Moderate seed predation by Blue-Fronted Amazons either at trees with large fruit crops or in areas where fruiting trees were aggregated implies in an enhanced probability of E. gracilipes seed survival and consequent regeneration success.

  1. Duet function in the yellow-naped amazon, Amazona auropalliata: evidence from playbacks of duets and solos.

    2012-01-01

    The question of why animals participate in duets is an intriguing one, as many such displays appear to be more costly to produce than individual signals. Mated pairs of yellow-naped amazons, Amazona auropalliata, give duets on their nesting territories. We investigated the function of those duets with a playback experiment. We tested two hypotheses for the function of those duets: the joint territory defense hypothesis and the mate-guarding hypothesis, by presenting territorial pairs with three types of playback treatments: duets, male solos, and female solos. The joint territory defense hypothesis suggests that individuals engage in duets because they appear more threatening than solos and are thus more effective for the establishment, maintenance and/or defense of territories. It predicts that pairs will be coordinated in their response (pair members approach speakers and vocalize together) and will either respond more strongly (more calls and/or more movement) to duet treatments than to solo treatments, or respond equally to all treatments. Alternatively, the mate-guarding hypothesis suggests that individuals participate in duets because they allow them to acoustically guard their mate, and predicts uncoordinated responses by pairs, with weak responses to duet treatments and stronger responses by individuals to solos produced by the same sex. Yellow-naped amazon pairs responded to all treatments in an equivalently aggressive and coordinated manner by rapidly approaching speakers and vocalizing more. These responses generally support the joint territory defense hypothesis and further suggest that all intruders are viewed as a threat by resident pairs.

    Administration of intranasal midazolam (2 mg/kg) was evaluated for sedation and effects on cloacal temperature, respiratory rate, and heart rate in manually restrained Hispaniolan Amazon parrots (Amazona ventralis). Adult parrots (n=9) were administered either midazolam (2 mg/kg) or an equal volume of saline solution intranasally before a 15-minute manual restraint in a complete crossover study. Respiratory rate and sedation scores were recorded before and during capture and during and after 15 minutes of manual restraint. Heart rate and cloacal temperature were recorded during manual restraint. After restraint, the parrots received intranasal flumazenil (0.05 mg/kg) or an equal volume of saline solution, and the recovery time was recorded. In those birds that received midazolam, sedation was observed within 3 minutes of administration, and vocalization, flight, and defense responses were significantly reduced during capture. During manual restraint, the mean rate of cloacal temperature increase was significantly slower and remained significantly lower in birds that received midazolam compared with controls. Mean respiratory rates were significantly lower for up to 12 minutes in parrots that received midazolam compared with those receiving saline solution. Flumazenil antagonized the effects of midazolam within 10 minutes. No overt clinical adverse effects to intranasal midazolam and flumazenil administration were observed. Further studies on the safety of intranasal midazolam and flumazenil in this species are warranted.

    To determine pharmacokinetics after IV and oral administration of a single dose of tramadol hydrochloride to Hispaniolan Amazon parrots (Amazona ventralis). 9 healthy adult Hispaniolan Amazon parrots (3 males, 5 females, and 1 of unknown sex). Tramadol (5 mg/kg, IV) was administered to the parrots. Blood samples were collected from -5 to 720 minutes after administration. After a 3-week washout period, tramadol (10 and 30 mg/kg) was orally administered to parrots. Blood samples were collected from -5 to 1,440 minutes after administration. Three formulations of oral suspension (crushed tablets in a commercially available suspension agent, crushed tablets in sterile water, and chemical-grade powder in sterile water) were evaluated. Plasma concentrations of tramadol and its major metabolites were measured via high-performance liquid chromatography. Mean plasma tramadol concentrations were > 100 ng/mL for approximately 2 to 4 hours after IV administration of tramadol. Plasma concentrations after oral administration of tramadol at a dose of 10 mg/kg were 100 ng/mL for approximately 6 hours after administration. Oral administration of the suspension consisting of the chemical-grade powder resulted in higher plasma tramadol concentrations than concentrations obtained after oral administration of the other 2 formulations; however, concentrations differed significantly only at 120 and 240 minutes after administration. Oral administration of tramadol at a dose of 30 mg/kg resulted in plasma concentrations (> 100 ng/mL) that have been associated with analgesia in Hispaniolan Amazon parrots.

    To evaluate the thermal antinociceptive effects and duration of action of nalbuphine decanoate after IM administration to Hispaniolan Amazon parrots (Amazona ventralis). 10 healthy adult Hispaniolan Amazon parrots of unknown sex. Nalbuphine decanoate (33.7 mg/kg) or saline (0.9% NaCl) solution was administered IM in a randomized complete crossover experimental design (periods 1 and 2). Foot withdrawal threshold to a noxious thermal stimulus was used to evaluate responses. Baseline thermal withdrawal threshold was recorded 1 hour before drug or saline solution administration, and thermal foot withdrawal threshold measurements were repeated 1, 2, 3, 6, 12, 24, 48, and 72 hours after drug administration. Nalbuphine decanoate administered IM at a dose of 33.7 mg/kg significantly increased thermal foot withdrawal threshold, compared with results after administration of saline solution during period 2, and also caused a significant change in withdrawal threshold for up to 12 hours, compared with baseline values. Nalbuphine decanoate increased the foot withdrawal threshold to a noxious thermal stimulus in Hispaniolan Amazon parrots for up to 12 hours and provided a longer duration of action than has been reported for other nalbuphine formulations. Further studies with other types of nociceptive stimulation, dosages, and dosing intervals as well as clinical trials are needed to fully evaluate the analgesic effects of nalbuphine decanoate in psittacine birds.

    Psittacines are generally considered to possess cognitive abilities comparable to those of primates. Most psittacine research has evaluated performance on standardized complex cognition tasks, but studies of basic cognitive processes are limited. We tested orange-winged Amazon parrots (Amazona amazonica) on a spatial foraging assessment, the Hamilton search task. This task is a standardized test used in human and non-human primate studies. It has multiple phases, which require trial and error learning, learning set breaking, and spatial memory. We investigated search strategies used to complete the task, cognitive flexibility, and long-term memory for the task. We also assessed the effects of individual strength of motor lateralization (foot preference) and sex on task performance. Almost all (92%) of the parrots acquired the task. All had significant foot preferences, with 69% preferring their left foot, and showed side preferences contralateral to their preferred limb during location selection. The parrots were able to alter their search strategies when reward contingencies changed, demonstrating cognitive flexibility. They were also able to remember the task over a 6-month period. Lateralization had a significant influence on learning set acquisition but no effect on cognitive flexibility. There were no sex differences. To our knowledge, this is the first cognitive study using this particular species and one of the few studies of cognitive abilities in any Neotropical parrot species.

    The efficacy and safety of topically applied rocuronium in Hispaniolan Amazon parrots ( Amazona ventralis ) was assessed in a group of 10 adult birds. A complete ophthalmic examination (including Schirmer tear test, ocular reflexes, applanation tonometry, fluorescein staining, and slit-lamp biomicroscopy) was performed, and rocuronium bromide (0.15 mg in both eyes) was administered. Pupillary light reflex (PLR) and pupillary diameter were recorded in a darkened room at the following time points: 0, 10, 20, 30, 40, 50, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 300, and 360 minutes, and 24 hours. Fluorescein staining in both eyes was performed at 24 hours. By 10 minutes, PLR was absent in all birds (at 5 minutes, 8 birds; at 10 minutes, remaining 2 birds). Pupil diameter differed significantly from baseline at all time points. Additionally, PLR was decreased in 7/10 birds at 360 minutes and normal in all birds at 24 hours. Superficial corneal ulceration was observed at 24 hours in the left eye of 2/10 of the birds after fluorescein stain application. This study demonstrated that rocuronium bromide was an effective mydriatic agent in Hispaniolan Amazon parrots with rapid onset and prolonged duration of action.

    A three-dimensional (3D) prosthesis was designed and built for a red-lored Amazon parrot ( Amazona autumnalis) with a pre-existing amputation of the distal left leg at the tibiotarsal-tarsometatarsal joint and injuries to the right leg caused by cage companion aggression. The prosthesis consisted of a straight main imprint, with a round element at both ends to provide stability, and a bridge connecting this to a socket without a bottom where the stump could be accommodated and held securely with self-adhesive bandaging. Over a 4-month period, 3 different 3D prosthetic models were made and evaluated. The first model was fitted, but the parrot would only use the tip of the main imprint to stand and walk. The second model was designed with a semicircular imprint with only 1 round element at the cranial end, a different bridge to accommodate the change to the main imprint, and the same socket. With these changes, the parrot was able to place the imprint of the prosthesis on the floor to stand and move freely around its enclosure. To accommodate morphologic changes on the stump, a third model was created consisting of the same imprint and bridge, but the socket was cut vertically all the way on one side to allow distention on its diameter and provide a long-lasting fit to the stump over time.

    The red-tailed Amazon parrot (Amazona brasiliensis) is a threatened species of psittacine bird that inhabit coastal regions of Brazil. In view of the threat of this species, the aim of this study was to perform a health evaluation in wild nestlings in Rasa Island, determining the prevalence of enterobacteria and infectious agents according to type of nest. Blood samples were collected from 64 birds and evaluated for antibodies of Chlamydia psittaci by commercial dot-blot ELISA. Cloacal and oropharyngeal swabs samples were collected from 23 birds from artificial wooden nests, 15 birds from PVC nests and 2 birds from natural nests for microbiological analysis. Swab samples were collected from 58 parrots for C. psittaci detection by PCR and from 50 nestlings for Avian Influenza, Newcastle Disease and West Nile viruses' detection analysis by real-time RT-PCR. Ten bacterial genera and 17 species were identified, and the most prevalent were Escherichia coli and Klebsiella oxytoca. There was no influence of the type of nest in the nestlings' microbiota. All samples tested by ELISA and PCR were negative. There is currently insufficient information available about the health of A. brasiliensis and data of this study provide a reference point for future evaluations and aid in conservation plans.

    Captive breeding is a widespread conservation strategy, yet such programs rarely include empirical genetic data for assessing management assumptions and meeting conservation goals. Cuban Amazon parrots (Amazona leucocephala) are considered vulnerable, and multiple on-island captive populations have been established from wild-caught and confiscated individuals of unknown ancestry. Here, we used mitochondrial haplotypic and nuclear genotypic data at 9 microsatellite loci to quantify the extent and distribution of genetic variation within and among captive populations in Zapata Swamp and Managua, Cuba, and to estimate kinship among breeders (n = 88). Using Bayesian clustering analysis, we detected 2 distinct clusters within the Zapata population, one of which was shared with Managua. Individuals from the cluster unique to Zapata possessed mitochondrial haplotypes with affinities to Cuban subspecies (A. l. leucocephala, A. l. palmarum); the shared cluster was similar, but also included haplotypes closely related to the subspecies restricted to Cayman Brac (A. l. hesterna). Overall mean kinship was low within each captive population (-0.026 to -0.012), with 19 and 11 recommended breeding pairs in Zapata and Managua, respectively, ranked according to mean kinship and informed by molecular sexing. Our results highlight the importance of understanding population history within ex situ management programs, while providing genetic information to directly inform Cuban parrot conservation. © The American Genetic Association 2015.

    Cloacal or fecal Gram's stains and bacterial cultures are routinely performed during avian physical examinations to assess the microbial flora of the gastrointestinal tract. Although cloacal or fecal Gram's stains and bacterial cultures are considered routine diagnostic procedures, the level of agreement between the individual tests has not been determined. To investigate the level of agreement between results from Gram's stain and bacterial culture when used to assess cloacal or fecal samples from psittacine birds, samples were taken from 21 clinically healthy Hispaniolan Amazon parrots ( Amazona ventralis ) and tested by Gram's stain cytology and bacterial culture. Most bacteria (97.2%) identified by Gram's stain were gram positive. However, gram-negative organisms were identified in 7 of 21 (33.3%; 95% confidence interval: 13.3%-53.3%) birds. Escherichia coli was the only gram-negative organism identified on culture. Agreement between results of Gram's stain and culture was fair (weighted κ = 0.27). The results of this study suggest that Gram's stains and bacterial culture may need to be performed with a parallel testing strategy to limit the likelihood of misclassifying the microbial flora of psittacine patients.

    Full Text Available O estudo tem por objetivo documentar o uso de animais na medicina caseira entre ribeirinhos do rio Negro, Amazonas, Brasil. Os dados foram coletados por meio de 92 entrevistas e de observações sobre o conhecimento e as práticas cotidianas de uso de animais medicinais. Cerca de 60 espécies animais são conhecidas com propósitos medicinais. O conhecimento é bem distribuído entre os sexos (homens e mulheres e entre localidades (urbano e rural. O uso de animais medicinais está imerso em conceitos etiológicos e envolve uma complexa visão cosmológica do processo de cura. O êxodo rural e o acesso facilitado à medicina ocidental podem promover a perda dos conhecimentos tradicionais, o que pode ser mitigado através da valorização e da transmissão desses saberes às futuras gerações.

    Full Text Available The Fundação de Medicina Tropical Dr. Heitor Vieira Dourado (FMT-HVD, located in Manaus, the capital of the State of Amazonas (Western Brazilian Amazon, is a pioneering institution in this region regarding the syndromic surveillance of acute febrile illness, including arboviral infections. Based on the data from patients at the FMT-HVD, we have detected recurrent outbreaks in Manaus by the four dengue serotypes in the past 15 years, with increasing severity of the disease. This endemicity has culminated in the simultaneous circulation of all four serotypes in 2011, the first time this has been reported in Brazil. Between 1996 and 2009, 42 cases of yellow fever (YF were registered in the State of Amazonas, and 71.4% (30/42 were fatal. Since 2010, no cases have been reported. Because the introduction of the yellow fever virus into a large city such as Manaus, which is widely infested by Aedes mosquitoes, may pose a real risk of a yellow fever outbreak, efforts to maintain an appropriate immunization policy for the populace are critical. Manaus has also suffered silent outbreaks of Mayaro and Oropouche fevers lately, most of which were misdiagnosed as dengue fever. The tropical conditions of the State of Amazonas favor the existence of other arboviruses capable of producing human disease. Under this real threat, represented by at least 4 arboviruses producing human infections in Manaus and in other neighboring countries, it is important to develop an efficient public health surveillance strategy, including laboratories that are able to make proper diagnoses of arboviruses.

A inundação é um evento natural que promove mudanças na estrutura e composição florística dessas comunidades. O conhecimento da diversidade de espécies é de fundamental importância para o entendimento da dinâmica da regeneração natural de espécies nos ecossistemas amazônicos. Este trabalho teve como objetivo levantar a composição florística do solo do fundo do lago do Manaquiri-AM, em um período de seca excepcional, ocorrida em 2005, na Amazônia. Foram realizadas coletas de material botânico em duas áreas do lago, em novembro de 2005; para a amostragem, utilizou-se um quadrado de madeira de 0,36 m², atirado aleatoriamente por 20 vezes em cada local de estudo. A vegetação emergente foi de 5.958 indivíduos, distribuídos em sete famílias e nove espécies. As famílias mais representativas em número de espécies foram Poaceae e Cyperaceae. Cyperus esculentus e Luziola spruceana foram as mais frequentes, e Mimosa pudica e Alternanthera sessilis, as de maior abundância. C. esculentus e M. pudica apresentaram maior número de indivíduos, de densidade e de valor de importância.

    Full Text Available La energía potencial del agua presenta diferencias de un punto del suelo a otro; esas diferencias son las que originan el movimiento del agua de acuerdo a la tendencia universal de la materia en el sentido de moverse de donde la energía potencial es mayor a donde dicha energía es menor. En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

Five preliminary experiments (2 birds/experiment) were performed to determine the ideal dose for this species. The formulation then was administered (12.5 mg/kg, SC) to 8 birds. Blood samples were collected before (time 0) and 0.08, 0.5, 1, 2, 4, 8, 12, and 24 hours after drug administration. Some birds were used more than once, with a washout period of ≥ 3 months between subsequent treatments. Butorphanol concentrations were quantitated by use of liquid chromatography-tandem mass spectrometry. Pharmacokinetic analysis was performed by use of noncompartmental analysis. RESULTS Maximal plasma butorphanol concentration was reached at 1.31 hours. Plasma concentrations of butorphanol remained > 100 ng/mL for > 3 hours (all birds) or > 4 hours (5/8 birds) but Amazon parrots, and absorption followed a pharmacokinetic profile compatible with a sustained-release drug. A dose of 12.5 mg/kg, SC, would theoretically provide analgesia for 4 to 8 hours. No adverse effects were detected. Studies on the pharmacodynamics of this formulation are necessary to confirm the degree and duration of analgesia.

    Full Text Available Resumo: A crescente demanda de mercado por produtos florestais não madeireiros oferece uma oportunidade de desenvolvimento econômico que poderia aliar a inclusão social produtiva de agricultores familiares com a conservação dos ecossistemas florestais. No entanto, o aumento da produção poderá significar a substituição do manejo extrativo das florestas pelo monocultivo, anulando seus efeitos positivos quanto à conservação das florestas. Buscou-se identificar os fatores determinantes que levam os agricultores familiares tradicionais do baixo rio Manacapuru a se engajarem na atividade extrativista ou de cultivo do açaí-da-mata (Euterpe precatória, a espécie nativa do estado do Amazonas. Dado que a coleta extrativa dos frutos é feita mediante a escala das árvores, a decisão de produção parece depender principalmente da oferta de mão de obra masculina jovem, de trabalhadores com a habilidade e força física para realizar essa tarefa. Já a decisão de cultivo pode estar associada à maior disponibilidade de capital financeiro que as famílias obtêm da renda das atividades agrícolas. As famílias que cultivam o açaí mantiveram a prática de coleta extrativa, indicando que o plantio de pequenas áreas de cultivos consorciados representa uma estratégia de aumento da produção sem que necessariamente haja a completa substituição do extrativismo pelo cultivo da espécie.

    Full Text Available The abundance and distribution of ichthyoplankton and their relationships to current velocity, temperature, dissolved oxygen, pH and electrical conductivity of the water in the Anavilhanas Ecological Station, Negro River, Amazonas State, Brazil, were analyzed. Preferred microhabitats for spawning, dispersion and nursery were also verified. Sampling was undertaken during the falling water period of 2001 and the rising water period of 2002, in a section of 100 km subdivided into 5 subsections, with a total of 20 stations (5 beaches, 5 ravines, 5 channels, and 5 lake channels at night and during the day at the surface and at the bottom. 647 eggs and 4,187 larvae were captured, belonging to 10 families and four orders: Characiformes (6, Siluriformes (2, Perciformes (1, and Clupeiformes (1. Engraulidae (55.39%, Pimelodidae (30.45%, Auchenipteridae (5.23% and Sciaenidae (5.13% were the dominant families. The hierarchical statistical model (ANOVA with three factors (microhabitat, depth and period was applied to the environmental variables and the larval abundance, showing greater abundances of sciaenids in the ravines and lower abundances of engraulids in the channels. The highest captures were obtained at lower temperature values, at the bottom during the day and at the surface at night, suggesting an active larval behavior. The presence of the four larval development stages in all subsection for pimelodids and sciaenids, and in three subsections for engraulids, indicates that the Anavilhanas Ecological Station is an important spawning and nursery area for species of these groups in the Negro River. Larvae abundance of all characiform families was extremely low (from 0.1 to 1.17%, suggesting that they do not spawn in this system.

    To compare pharmacokinetics after IV, IM, and oral administration of a single dose of meloxicam to Hispaniolan Amazon parrots (Amazona ventralis). 11 healthy parrots. Cohorts of 8 of the 11 birds comprised 3 experimental groups for a crossover study. Pharmacokinetics were determined from plasma concentrations measured via high-performance liquid chromatography after IV, IM, and oral administration of meloxicam at a dose of 1 mg/kg. Initial mean ± SD plasma concentration of 17.3 ± 9.0 μg/mL was measured 5 minutes after IV administration, whereas peak mean concentration was 9.3 ± 1.8 μg/mL 15 minutes after IM administration. At 12 hours after administration, mean plasma concentrations for IV (3.7 ± 2.5 μg/mL) and IM (3.5 ± 2.2 μg/mL) administration were similar. Peak mean plasma concentration (3.5 ± 1.2 μg/mL) was detected 6 hours after oral administration. Absolute systemic bioavailability of meloxicam after IM administration was 100% but was lower after oral administration (range, 49% to 75%). Elimination half-lives after IV, IM, and oral administration were similar (15.9 ± 4.4 hours, 15.1 ± 7.7 hours, and 15.8 ± 8.6 hours, respectively). Pharmacokinetic data may provide useful information for use of meloxicam in Hispaniolan Amazon parrots. A mean plasma concentration of 3.5 μg/mL would be expected to provide analgesia in Hispaniolan Amazon parrots; however, individual variation may result in some birds having low plasma meloxicam concentrations after IV, IM, or oral administration. After oral administration, meloxicam concentration slowly reached the target plasma concentration, but that concentration was not sustained in most birds.

    To determine plasma osmolality in healthy adult Hispaniolan Amazon parrots (Amazona ventralis) and validate osmolality equations in these parrots. 20 healthy adult Hispaniolan Amazon parrots. A blood sample (0.5 mL) was collected from the right jugular vein of each parrot and placed into a lithium heparin microtainer tube. Samples were centrifuged, and plasma was harvested and frozen at -30 degrees C. Samples were thawed, and plasma osmolality was measured in duplicate with a freezing-point depression osmometer. The mean value was calculated for the 2 osmolality measurements. Plasma osmolality values were normally distributed, with a mean +/- SD of 326.0 +/- 6.878 mOsm/kg. The equations (2 x [Na(+) + K(+)]) + (glucose/18), which resulted in bias of 2.3333 mOsm/kg and limits of agreement of -7.0940 to 11.7606 mOsm/kg, and (2 x [Na(+) + K(+)]) + (uric acid concentration/16.8) + (glucose concentration/18), which resulted in bias of 5.8117 mOsm/kg and limits of agreement of -14.6640 to 3.0406 mOsm/kg, yielded calculated values that were in good agreement with the measured osmolality. IV administration of large amounts of hypotonic fluids can have catastrophic consequences. Osmolality of the plasma from parrots in this study was significantly higher than that of commercially available prepackaged fluids. Therefore, such fluids should be used with caution in Hispaniolan Amazon parrots as well as other psittacines. Additional studies are needed to determine whether the estimation of osmolality has the same clinical value in psittacines as it does in other animals.

    A 25-year-old yellow-naped Amazon parrot (Amazona ochrocephala auropalliata) was presented for nasal discharge and sneezing. Physical examination revealed poor feather quality, a mild serous nasal discharge, and a mass on the dorsal surface of the oral cavity. Cytologic examination of a mass aspirate as well as results of a choanal culture revealed squamous metaplasia of the salivary glands and bacterial rhinitis, respectively. Following resolution of the presenting conditions, the patient was presented for hind limb weakness and ataxia. The clinical signs were transient and generally resolved with rest but could be reproduced after stressful episodes, such as restraint for procedures or treatment. Test results from a complete blood count, biochemistry profile, whole-body radiographs, needle electromyography of the leg muscles, and an edrophonium challenge test were within reference limits. Based on the clinical signs and results of the diagnostic workup, the presumptive diagnosis was intermittent claudication, a condition caused by peripheral vascular disease and defined as intermittent weakness and pain in the legs induced by exercise and relieved by rest. Shortly after initiation of treatment with isoxsuprine, the bird died. Postmortem examination and histopathology revealed severe atherosclerotic lesions throughout the vascular system with stenotic lesions present in the abdominal aorta and femoral arteries. Electron microscopic examination of the great arteries was also performed and helped to further characterize the nature of the lesions. This case is the first report, to our knowledge, of an intermittent claudication-like syndrome associated with peripheral atherosclerosis in a psittacine bird. In addition, the distribution and some of the macroscopic and histopathologic features of the lesions differ from previous descriptions of atherosclerosis in psittacine birds.

    OBJECTIVE :To determine the mydriatic effects of topical rocuronium bromide administration in Hispaniolan Amazon parrots (Amazona ventralis) and to identify any adverse effects associated with treatment. Randomized crossover study. 8 healthy adult Hispaniolan Amazon parrots. Rocuronium bromide (20 μL/eye; 10 mg/mL) or saline (20 μL/eye; 0.9% NaCl) solution was administered in both eyes of each bird with a 26-day washout period. The birds were manually restrained in lateral recumbency with the apex of the cornea positioned upward for 2 minutes following administration in each eye. Infrared pupillometry and direct pupillary light reflex measurements were used to evaluate the mydriatic effects. Pupillary measurements were recorded prior to administration and every 20 minutes for 2 hours after administration, then hourly for a total of 7 hours. A brief physical examination was performed, direct pupillary light reflex was tested, and fluorescein staining was performed on each eye of each bird 24 hours after administration. A significant difference in pupillary diameter for the active versus control treatment group was noted from 20 to 360 minutes after drug administration, but not at 420 minutes. Minimal adverse effects were noted. Three birds had transient inferior eyelid paresis noted in both eyes after receiving rocuronium; 24 hours after the treatment, no differences in ocular measurements existed between the active and control treatments. Results suggested that topical rocuronium bromide administration may be safely used for pupillary dilation in Hispaniolan Amazon parrots and could be used for clinical evaluation, fundus imaging, and surgical interventions involving the lens and posterior segment in this species.

    The luteinizing hormone-releasing hormone agonist leuprolide acetate is used commonly to anage reproductive problems in pet birds. To determine the effect of leuprolide acetate on plas a and fecal hormone levels in a psittacine species, a single 800 microg/kg dose of the 30-day depot form of leuprolide acetate was administered IM in 11 healthy, nonbreeding adult Hispaniolan Amazon parrots (Amazona ventralis), and plasma and fecal hormone levels were measured before and after leuprolide administration. At pooled baseline to 21 days postleuprolide acetate administration, sample collection day was significantly associated with plasma 17beta-estradiol and androstenedione levels and fecal 17beta-estradiol levels (evaluated in females only). Both plasma androstenedione and plasma 17beta-estradiol levels decreased significantly from baseline to a nadir at 7 days postleuprolide acetate administration but did not differ significantly 14 days later from that nadir or from pooled baseline samples, suggesting that the effect of leuprolide on hormone levels remained about 2 weeks. Fecal 17beta-estradiol levels increased significantly from the nadir at 7 days postleuprolide to 21 days postleuprolide administration, with trends of the level at 21 days postleuprolide being higher than the pooled baseline level and of decreasing levels from pooled baseline to 7 days postleuprolide administration. Plasma luteinizing hormone and fecal testosterone levels did not change significantly from baseline levels after leuprolide administration over the 2-day period. No significant correlations were found between plasma hormone and fecal hormone levels. These results suggest that measurement of plasma androstenedione, plasma 17beta-estradiol, and fecal 17beta-estradiol levels might be useful in assessing the effects of 30-day depot leuprolide acetate in Hispaniolan Amazon parrots.

      Increased glucocorticoids cause a characteristic stress leukogram in mammalian taxa. It is assumed that avians exhibit a similar response, but to date, there have been no controlled studies to correlate serial endogenous corticosterone levels to hematologic values. An established flock of 18 Hispaniolan Amazon parrots ( Amazona ventralis) was used as a model in a crossover study. The treatment group was subjected to the stress of transport, restraint, and common clinical procedures with serial blood samples collected at 20-min intervals for hematology and corticosterone levels; the control group was sampled at the same intervals. Longitudinal data analysis was performed with linear mixed modeling. For all hematologic analytes, the baseline value had a significant positive effect on subsequent values (all P < 0.001). The white blood cell, heterophil, and eosinophil counts and heterophil to lymphocyte ratio increased over time in the treatment group, whereas it remained stable in the control group ( P = 0.016, P < 0.001, P < 0.001, P = 0.02, respectively, for the time*treatment effect). Lymphocyte absolute counts decreased over time, although not significantly; the decrease was significant for the relative lymphocyte count in the treatment group. Monocytes and basophils were not significantly altered. The treatment group had a higher mean corticosterone level overall than the control group by approximately 60% ( P = 0.008). The mean corticosterone level also increased over time in both groups by three- to fourfold ( P < 0.001) by 20 min then plateaued. These results demonstrate that some significant hematologic changes may arise with routine handling and transportation of birds and should be accounted for in hematologic interpretation of cell counts.

    Long-term anticonvulsive treatments have been poorly described in birds, and few pharmacokinetic studies have been performed, with mixed results. Levetiracetam, a new anticonvulsive drug, has shown good efficacy for monotherapy or adjunctive treatment of seizures in both human and veterinary medicine. To determine pharmacokinetics of levetiracetam in Hispaniolan Amazon parrots ( Amazona ventralis ), 20 healthy birds were randomly divided into 2 groups and administered either a 50 mg/kg (n = 10) or a 100 mg/kg (n = 10) oral dose of levetiracetam with no observable adverse effects. Blood samples were collected at baseline and at 12 time intervals (6 per group) for 16 hours. The concentration-time profiles resembled characteristic absorption, with maximum plasma concentrations of 61.0 μg/mL and 95.1 μg/mL at 60 minutes; terminal half-lives at 2.38 and 2.37 hours; volumes of distribution of 0.807 and 0.773 L/kg, with an area under the curve at 14 100 and 28 820 mg × min/L; and clearance rates of 3.65 and 3.60 mL/min per kg, respectively. Plasma concentrations were greater than 5.5 mg/L for up to 9.4 and 12 hours, suggesting an 8- and 12-hour oral dosing at 50 and 100 mg/kg, respectively, would be sufficient to maintain targeted values. Clinically, doses and frequencies may need escalation based on differences in species and individuals, and drug levels should be monitored.

    Meloxicam has been shown to have a safe and favorable pharmacodynamic profile with individual variability in Hispaniolan Amazon parrots (Amazona ventralis). In the current study, we determined the pharmacokinetics of a sustained-release formulation of meloxicam after subcutaneous administration to Hispaniolan Amazon parrots. Twelve healthy adult parrots, 6 males and 6 females, were used in the study. Blood samples were collected before (time 0) and at 0.5, 1, 2, 6, 12, 24, 48, 72, 96, and 120 hours after a single dose of the sustained-release meloxicam formulation (3 mg/kg SC). Plasma meloxicam concentrations were measured by high-pressure liquid chromatography. Pharmacokinetic parameters were determined by noncompartmental analysis. Plasma concentrations reached a mean C max of 23.4 μg/mL (range, 14.7-46.0 μg/mL) at 1.8 hours (range, 0.5-6 hours), with a terminal half-life of 7.4 hours (range, 1.4-40.9 hours). Individual variation was noticeable, such that some parrots (4 of 12 birds) had very low plasma meloxicam concentrations, similar to the high variability reported in a previous pharmacokinetic study of the standard meloxicam formulation in the same group of birds. Two birds developed small self-resolving scabs at the injection site. On the basis of these results, the sustained-release meloxicam formulation could be administered every 12 to 96 hours in Hispaniolan Amazon parrots to manage pain. Because of these highly variable results, the use of this formulation in this species cannot be recommended until further pharmacokinetic, safety, and pharmacogenomic evaluations are performed to establish accurate dosing recommendations and to understand the high pharmacokinetic variability.

    To determine the pharmacokinetics and safety of voriconazole administered orally in single and multiple doses in Hispaniolan Amazon parrots (Amazona ventralis). 15 clinically normal adult Hispaniolan Amazon parrots. Single doses of voriconazole (12 or 24 mg/kg) were administered orally to 15 and 12 birds, respectively; plasma voriconazole concentrations were determined at intervals via high-pressure liquid chromatography. In a multiple-dose trial, voriconazole (18 mg/kg) or water was administered orally to 6 and 4 birds, respectively, every 8 hours for 11 days (beginning day 0); trough plasma voriconazole concentrations were evaluated on 3 days. Birds were monitored daily, and clinicopathologic variables were evaluated before and after the trial. Voriconazole elimination half-life was short (0.70 to 1.25 hours). In the single-dose experiments, higher drug doses yielded proportional increases in the maximum plasma voriconazole concentration (C(max)) and area under the curve (AUC). In the multiple-dose trial, C(max), AUC, and plasma concentrations at 2 and 4 hours were decreased on day 10, compared with day 0 values; however, there was relatively little change in terminal half-life. With the exception of 1 voriconazole-treated parrot that developed polyuria, adverse effects were not evident. In Hispaniolan Amazon parrots, oral administration of voriconazole was associated with proportional kinetics following administration of single doses and a decrease in plasma concentration following administration of multiple doses. Oral administration of 18 mg of voriconazole/kg every 8 hours would require adjustment to maintain therapeutic concentrations during long-term treatment. Safety and efficacy of voriconazole treatment in this species require further investigation.

    Full Text Available In the first two decades of the 20th century, publications of Euclides da Cunha, Alberto Rangel and Carlos Chagas about the Amazon presented from different perspectives a critique of what they considered unrealistic visions originated in the travel accounts of naturalists of 18th and 19th centuries. Alternatively, they proposed the analysis of the region from the perspective of new scientific knowledge, which included several areas - from geology to tropical medicine. Recent studies have indicated the need for more research on the institutions and local scientific practices, both in the development of ideas about the region and the definition of public policies. This article is proposed on this perspective, to reflect on the different ideas that were built by the medical-scientific thought about Nature and Society in the state of Amazonas during the Brazilian First Republic, when the rise and decline of the Amazonian rubber was experienced. It is understood that local physicians actively participated in scientific discussions related to tropical medicine, and put into practice the main theses about control and prevention of endemic diseases like malaria and yellow fever. This set of ideas and practices contributed to the definition of sanitation of the city of Manaus and the hinterland of state of Amazonas.

    The Yellow-shouldered Amazon (Amazona barbadensis) is the sole parrot of the genus Amazona that inhabits only dry forests. Its population has been dropping; therefore it has been the topic of many studies and conservation efforts. However, the phylogenetic relationship of this species to potential relatives classified within the Yellow-Headed Amazon (YHA) complex are still not clear. Therefore, we used more extensive data sets, including the newly sequenced mitochondrial genome of A. barbadensis, to conduct phylogenetic analyses. Various combinations of genes and many phylogenetic approaches showed that A. barbadensis clustered significantly with A. ochrocephala ochrocephala from Colombia and Venezuela, which created the Northern South American (NSA) lineage, clearly separated from two other lineages within the YHA complex, the Central (CA) and South American (SA). Tree topology tests and exclusion of rapidly evolving sites provided support for a NSA+SA grouping. We propose an evolutionary scenario for the YHA complex and its colonization of the American mainland. The NSA lineage likely represents the most ancestral lineage, which derived from Lesser Antillean Amazons and colonized the northern coast of Venezuela about a million years ago. Then, Central America was colonized through the Isthmus of Panama, which led to the emergence of the CA lineage. The southward expansion to South America and the origin of the SA lineage happened almost simultaneously. However, more intensive or prolonged gene flow or migrations have led to much weaker geographic differentiation of genetic markers in the SA than in the CA lineage.

    Full Text Available Situado em Terra Indígena do Alto Rio Negro, Iauaretê é o segundo maior pólo de concentração humana no município de São Gabriel da Cachoeira (AM e agrega dez vilas, com 15 etnias. Esse distrito indígena vem sofrendo processo de transformação progressiva de padrão de ocupação disperso e ribeirinho para núcleo com feições urbanas, com aproximadamente 2700 habitantes, desencadeando problemas de saúde pública. Com objetivo de investigar a distribuição de prevalências de parasitos intestinais na população local e discutir a relação desse indicador de saúde com aspectos socioambientais no distrito de Iauaretê, foram realizadas análises da qualidade da água de abastecimento e exames parasitológicos em amostras de fezes e solo. Do total de amostras de água analisadas, 89,2% apresentaram resultado positivo para coliformes termotolerantes. Identificou-se que a vila Dom Bosco foi a que apresentou maior índice de prevalência em amostras fecais com 76% dos indivíduos parasitados. A vila São José apresentou o menor índice com 56%. Os parasitos mais prevalentes em amostras fecais positivas foram, em ordem decrescente, Ascaris lumbricoides (64,84%, Entamoeba coli (32,58%, Endolimax nana (14,84% e Blastoyistis hominis (13,39%. Em amostras de solo as prevalências mais significativas foram de ovos de Ascaris sp (52,6%, cistos de Entamoeba coli (52,6% e larvas de ancilostomídeos (52,6%. Concluiu-se que os altos índices de parasitoses intestinais na população, aliados à falta de saneamento básico e à manutenção de práticas sanitárias tradicionais constituem um quadro preocupante em saúde pública.The Iauaretê District is the second largest human concentration centre in the municipality of São Gabriel da Cachoeira, state of Amazonas.

Este trabalho identificou espécies de plantas daninhas colonizadas pelo fungo Colletotrichum guaranicola em cultivos de guaranazeiro em quatro municípios do Estado do Amazonas. As plantas daninhas foram identificadas e a presença do fungo foi verificada por meio de isolamentos feitos a partir de fragmentos de folhas lesionadas. As espécies colonizadas por C. guaranicola foram Bidens bipinnata, Chloris sp., Clidemia capitellata, Cyperus flavus, Elephantopus scaber, Euphorbia brasiliensis, Hemidiodia sp., Hyptis lantanifolia, Paspalum conjugatum, Physalis angulata e Synedrella nodiflora, as quais podem representar uma fonte de inóculo do patógeno, além das plantas de guaraná. A diversidade de plantas daninhas, em cultivos de guaranazeiro, reforça a importância de estabelecer práticas de manejo dessas plantas, principalmente em Maués, onde ocorreu maior colonização das espécies de plantas daninhas pelo fungo.Weed infestation may reduce grain guarana crops yield and host plant pathogens becoming potential inoculum sources. This research identified weed species colonized by the fungus Colletotrichum guaranicola in the guarana crop in four counties in the state of Amazon. The weeds were identified fungi presence was observed by isolation from leaf fragments of leaves injured by the fungi.

    Full Text Available O festival dos Bois-Bumbás de Parintins (AM alcançou nos últimos anos dimensões massivas, conjugando, de modo inesperado e criativo, padrões e temas culturais tradicionais a procedimentos e abordagens modernizantes. É hoje uma das grandes manifestações populares do Norte do Brasil, atraindo milhares de pessoas não só de Manaus (a capital do estado e cidades próximas, como de diversas partes do país. O artigo analisa-o a partir de uma perspectiva antropológica, centrada no estudo dos rituais. Tece considerações sobre o estudo e a história do folguedo no Brasil. Empreende uma etnografia do festival, situando-o no contexto da região amazônica e examinando a trajetória percorrida desde sua criação aos dias atuais. Sugere, finalmente, a interpretação do Bumbá como um novo nativismo que, ao valorizar as raízes regionais indígenas, afirma positivamente uma identidade cultural cabocla.In recent years, the Boi-Bumbá festival in Parintins, in the state of Amazonas, has reached massive proportions. In surprising and creative ways, the festival mixes traditional cultural patterns and themes together with modernizing procedures and approaches. It has now become a major expression of popular culture in North Brazil, drawing thousands of people not only from the state capital of Manaus and nearby cities but also from all over the country. The article analyzes the Boi-Bumbá from an anthropological perspective, centered on the study of rituals and including observations on the study and history of folguedo in Brazil. Looking from an ethnographic angle, the article situates the festival in the context of the Amazon and examines the road taken from its creation to today. In conclusion, the Bumbá is interpreted as a new nativism that serves as a positive affirmation of cabocla cultural identity by valuing indigenous regional roots.

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

    Calcium (Ca), phosphorus (P), and magnesium (Mg) are important elements for body homeostasis in several diseases associated with imbalances in the plasma concentration of these ions. This is the first published report of reference intervals for Mg in association with Ca and P levels for psittacine species. One milliliter of blood was collected from 26 Hispaniolan parrots (Amazona ventralis) and 24 African grey parrots (Psittacus erithacus). The plasma concentrations of Ca, P, and Mg were determined for each sample. Statistical analyses were performed including all data (analysis 1) and after exclusion of the subjects with Ca > or = 14.00 mg/dl (3.5 mmol) (analysis 2). The data from analysis 1 have a narrower interval than that observed in analysis 2. Following the normality test (Shapiro-Wilk, alpha = 0.05), the univariate and mean procedures were run. For the reference intervals, the lower and upper values were used, after elimination of the outliers calculated by Blom scores from the ranked variables. The analysis 1 references for the Hispaniolans were Ca = 8.80-10.40 mg/dl (2.20-2.60 mmol/L), P = 1.80-4.40 mg/dl (0.58-1.42 mmol/L), Mg = 1.80-3.10 mg/dl (0.74-1.27 mmol/L), and Ca:P ratio = 2.62-5.39; for the African greys analysis 1 references were Ca = 8.20-20.20 mg/dl (2.05-5.05 mmol/L), P = 2.50-5.90 mg/dl (0.81-1.91 mmol/L), Mg = 2.10-3.40 mg/dl (0.82-1.4 mmol/L), and Ca:P ratio = 1.81-3.77. The analysis 2 references for the Hispaniolans were Ca = 8.80-10.30 mg/dl (2.20-2.58 mmol/L), P = 1.80-3.80 mg/dl (0.58-1.23 mmol/L), Mg = 1.90-3.00 mg/dl (0.82-1.07 mmol/L), Ca:P ratio = 2.62-5.39; for the African greys analysis 2 references were Ca = 1.07 mmol/L), Ca:P ratio = 1.67-3.50. The results of this study are important for evaluating Mg concentrations in relation to the Ca and P parameters in psittacines. This information will be particularly helpful for veterinarians evaluating the hypocalcemic syndrome in African grey parrots and other disease processes

    Full Text Available Este estudo providenciou a primeira investigação sobre impacto causado pela invasão da Oreochromis niloticus sobre a população de Cichlidae nativos da bacia hidrográfica Igarapé Fortaleza, um tributário do Rio Amazonas no estado do Amapá, no Norte do Brasil. Como uma consequência de escapes e/ou liberações intencionais de O. niloticus de pisciculturas, houve a invasão e estabelecimento dessa espécie de peixe exótico no ecossistema natural, especialmente em área de refúgio, alimentação e reprodução das espécies de ciclídeos nativos.  Os fatores que contribuíram para essa invasão e estabelecimento foram aqui discutidos. A invasão de O. niloticus está causando pressão sobre as populações de ciclídeos nativos, os quais encontram-se em baixa densidade populacional, pois 72,7% da biomassa dos ciclídeos (nativos e não nativos está constituída por O. niloticus. Consequentemente, a CPUE (2,489 kg.h-1 para essa tilápia invasora é muito superior aos valores da CPUE (0,641 kg.h-1 de todas as 16 espécies de ciclídeos nativos juntos. Os resultados indicam uma necessidade de plano de manejo para controle desse peixe invasor, evitando assim a extinção de espécies de ciclídeos nativos. Além disso, serão úteis também para a tomada de decisão crítica de instituições governamentais (estadual e federal quanto à aprovação da introdução de peixes não nativos na Amazônia ou qualquer outra região do país.

    Full Text Available Nesta revisão foram investigados os principais determinantes da transição epidemiológica, nutricional e do padrão de atividade física vivenciados pelos brasileiros nas últimas três décadas. Constata-se nestas pesquisas a exclusão sistemática da região Norte-rural do novo cenário epidemiológico nacional, atualmente caracterizado pelo declínio da desnutrição infantil e elevação concomitante da obesidade, além da ausência de informações científicas a respeito das condições de saúde, nutrição e sobrevivência das populações de praticamente todos os estados da região Norte. Especificamente para o estado do Amazonas é referida a menor estatura entre as crianças brasileiras, o que evidencia exposição à carências nutricionais de longa duração. Do mesmo modo, a análise evolutiva das pesquisas regionais caracteriza a persistência de um quadro grave de insegurança alimentar. Entretanto, sabe-se que a Amazônia é detentora de uma grande diversidade em peixes e frutos, o que deveria representar uma abundante oferta e utilização de proteína de boa qualidade biológica, calorias, vitaminas, minerais, e assim, viabilizar um adequado padrão de saúde, nutrição e qualidade de vida para sua população. A realidade social e econômica, bem como o quadro de precariedade da saúde e da nutrição da Região contrastam com a sua riqueza em recursos naturais. Para o entendimento deste evidente paradoxo foram investigados os componentes do bioma amazônico quanto à: heterogeneidade, complexidade, fragilidade, interatividade e suas relações com o potencial alimentar da região, bem como seu poder de influência na determinação do binômio saúde versus nutrição para os habitantes dos seus diferentes ecossistemas.In this review were investigated the principal determinants of the epidemic transition, nutritional and of the pattern of physical activity lived on by Brazilians in the last three decades.

    Full Text Available O estudo da composição da flora de plantas daninhas de uma área ou de uma região agrícola é importante, por identificar a diversidade de espécies e contribuir para recomendação de estratégias de manejo a serem empregadas nos sistemas agrícolas. Este trabalho teve o objetivo de identificar a composição florística de plantas daninhas em plantios de guaraná em cinco municípios (Coari, Iranduba, Maués, Presidente Figueiredo e Urucará do Estado do Amazonas. As plantas daninhas foram amostradas em áreas de produtores desses municípios e identificadas por classe, família e espécie. Foram coletados 14.707 indivíduos, distribuídos em 40 famílias e 87 espécies, das quais 70 eram Dicotiledôneas, 13 Monocotiledôneas e quatro Pteridófitas. As Dicotiledôneas apresentaram maior número de família e as Monocotiledôneas de indivíduos. As Pteridófitas ocorreram de forma inexpressiva em todos os municípios. As famílias Poaceae e Asteraceae apresentaram maior número de espécies. Panicum pilosum foi a espécie com maior número de indivíduos, freqüência, densidade e índice de valor de importância. Panicum laxum sobressaiu em Urucará e Iranduba; Scleria malaleuca, em Coari; e Chamaesyce hirta, em Maués. Homolepis aturensis, Paspalum conjugatum e Spermacoce capitata ocorreram nos cinco municípios. Em Maués foi encontrada a maior diversidade de espécies, e em Coari, o maior número de indivíduos.

Em 1992 e 2004, foi aplicado um questionário a 38 extratoras. Sementes das duas espécies de andiroba (Carapa procera D.C. e Carapa guianensis Aubl. foram utilizadas como matéria prima. O processo tradicional é complexo, demora cerca de dois meses e pode ser dividido em três etapas: 1. A coleta, seleção de sementes boas e um primeiro armazenamento (3-15 dias. 2. O preparo da massa pelo cozimento das sementes em água (1-3 horas, um segundo período de armazenamento (até 20 dias e finalizada pela retirada da casca e o amassamento das amêndoas. 3. A extração do óleo (até 30 dias, pelo gotejamento colocando a massa sobre uma superfície inclinada. Óleo extraído na sombra foi considerado de melhor qualidade do que no sol, porém o processo é mais demorado. Uma segunda extração com a prensa ("tipiti", usada na fabricação de farinha, foi raramente empregada. Verificaram-se pequenas variações entre os procedimentos das extratoras, aparentemente com conseqüências na rentabilidade e na qualidade do óleo. Na primeira e segunda etapa da extração participaram membros da família e/ou vizinhos, ao contrário da etapa final, realizada por uma única mulher. Enquanto, transmissão do conhecimento tradicional, em geral, costuma passar de geração por geração pela oralidade e observação, este estudo revelou, que os jovens não participam mais da extração.

Tivemos por objetivo avaliar se doadores de sangue do Hemocentro do Amazonas - Hemoam desenvolvem sideropenia sem anemia após doações consecutivas. A ferritina sérica foi medida em 528 doadores de sangue, do sexo masculino, com idade entre 18 a 61 anos, divididos em 313 doadores de repetição, com 4 ou mais doações regulares, e 215 primodoadores, que compareceram ao Hemocentro do Amazonas no período de setembro de 2001 a junho de 2002. Depleção do depósito de ferro, definida por níveis de ferritina menores de 20 ng/L, foi encontrada em 7,4% [16/215] dos primodoadores e em 48,6% [152/313] dos doadores de repetição. Utilizando-se de um critério mais rigoroso, como valores de ferritina A blood donation of 475 mL could deplete 242 ± 17 mg of iron from blood donors. The objective of this report is to evaluate if blood donors could develop sideropenia without anemia after several donations. Serum levels of ferritin were measured in 528 male blood donors, with ages ranging from 18 to 61 years old. A total of 313 of them had made 4 or more donations and 215 of them were first time donors. They donated blood in the Hemocentro do Amazonas - Hemoam, from September 2001 to June 2002. Deletion of iron stores characterized by serum ferritin levels of less than 20 ng/L was found in 7.4% (16/215 of first time donors, and in 48.6% (152/313 of multiple donors. With more stringent criteria of ferritin values less than 12 ng/L, 3.7% (8/215 of first-time donors as opposed to 24.9% (78/313 of multiple donors showed severe depletions. We concluded that multiple donors, after more than 5 repeated donations, are at risk of depleted iron and ferritin levels. It is important to implant protocols of iron supplementation for these donors to avoid damage to their health and

    2001-12-01

    Full Text Available Este artigo é uma análise das práticas e significados que permeiam a pesca do pirarucu nas comunidades rurais da Ilha de Ituqui, no Baixo Amazonas, Pará. O pirarucu é o maior peixe de escamas da Amazônia e também um valioso produto de mercado devido ao seu papel privilegiado na culinária local. A pesca do Pirarucu é uma das atividades mais antigas no Baixo Amazonas, remontando a tempos pré-coloniais. Para os pescadores que habitam a ilha de Ituqui, a captura do pirarucu pode representar não apenas o retorno econômico garantido de uma jornada de trabalho, como também revestir-se de uma série de significados e vivências ontologicamente estruturadas no dia-a-dia e na identidade dos pescadores. Conflitos sociais e disputas pessoais são intensificadas ou reduzidas, afeições são confirmadas e laços sociais refeitos através das práticas e encontros vivenciados durante uma viagem de pesca aos lagos próximos. Além da prática em si, tais viagens tornam-se referências mnemônicas e afetivas da paisagem, do evento de captura e do próprio sentido de lugar; resultando numa unidade processual conectada a muitas esferas pessoais e sociais de significado, as quais são de difícil compartimentalização. No meio de tantos aspectos motivadores, disputas e pescarias "irracionais" acontecem em Ituqui. Locais de pescaria são possessivamente guardados e "fronteiras territoriais" sutilmente estabelecidas entre comunidades e famílias. O direito ao recurso e, por extensão, aos significados e emoções que ele incorpora, torna-se um luxo ferozmente protegido por alguns. O decréscimo da população de pirarucus, as novas tecnologias de pesca, a alta demanda do mercado pelo peixe e a "mística" que ainda permeia a captura do animal colocaram muitos pescadores num dilema em que a sobrevivência desta atividade parece colidir com o que os desenvolvimentistas e ambientalistas chamam de "racionalidade" da conservação.This article aims to

    Full Text Available Este texto relata la historia de la llegada de la minería de aluvión a la región del Medio Caquetá (Amazonia Colombiana. Es narrado desde la experiencia de uno de los líderes de la comunidad multiétnica del Quinché-Metá, que agrupaba indígenas de varias etnias y colonos que buscaban organizarse como un resguardo multiétnico a inicios del siglo XXI. El texto comienza con la narración de ese proceso organizativo y los avances que habían logrado. Luego se cuenta cómo la llegada de las primeras balsas mineras, junto con guerrilleros y narcotraficantes, comienza a erosionar rápidamente todo el proceso y se van escalando los atropellos y muertes. El texto también cuenta sobre otras experiencias con la minería en el río Taraira. Concluye con la “reconquista” del ejército de la zona y cómo diez años después, en 2012, de nuevo han vuelto a ingresar balsas mineras en el río Caquetá.

    Full Text Available Las poblaciones indígenas en México son las más vulnerables, debido a que viven en condiciones de pobreza extrema y menor cumplimiento de sus derechos fundamentales. Se ha demostrado que los niños son el grupo que recibe mayor impacto sobre el desarrollo psicológico y físico.El presente trabajo tiene como objetivo describir la relación entre el nivel socioeconómico (NSE, habilidades intelectuales evaluadas con la Batería Woodcock-Muñoz y desnutrición en niños indígenas Tenek y Nahúa que viven en condiciones alta marginación. Los resultados muestran diferencias significativas entre los niños y niñas de nivel NSE bajo, NSE muy bajo y el rendimiento en las pruebas cognitivas que evalúan habilidad intelectual, inteligencia cristalizada e inteligencia visual. Respecto de los indicadores de desnutrición se observó una diferencia estadísticamente significativa para desnutrición aguda entre el NSE bajo y NSE muy bajo. Los efectos del nivel socioeconómico sobre las habilidades intelectuales y el estado nutricional han sido demostrados ampliamente, pero pocos estudios se han realizado con indígenas. Los hallazgos con estas poblaciones son un llamado urgente para las políticas públicas, considerando que el decremento en puntuaciones de habilidades intelectuales, y la desnutrición, en mediano y largo plazo representan graves costos en la calidad de vida, economía y desarrollo humano.

    Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. © 2009 Wiley-Liss, Inc.

La influencia de la medicina alópata está restringida principalmente a la prevención de enfermedades como poliomielitis, sarampión, viruela y paludismo. La medicina tradicional es más viable ante las condiciones socioeconómicas, fisiográficas y culturales en esta región. El objetivo de este estudio fue identificar las especies de plantas que utilizan los hñähñü con fines medicinales, el tipo de enfermedades que se tratan y la afinidad geográfica de las mismas. El trabajo de campo consistió en la realización de entrevistas abiertas a los pobladores del municipio y en la colecta de ejemplares en diferentes unidades "etnoecológicas". Se reporta el uso medicinal de 112 especies en el tratamiento de afecciones como susto, dolor de estómago, dolor del riñón, diarrea, fiebre, mal de ojo, entre otras. Aunque la mayoría de los habitantes conoce el uso medicinal de algunas plantas, los ancianos son más cultos, en la sabiduría hñähñü, como la de otras etnias de México, el pensamiento mágico-religioso forma parte de su cosmovisión y consideran la dualidad frío-caliente para el tratamiento. La gama de enfermedades que se presume curan las plantas registradas es muy amplio, desde la gripe hasta el cáncer. El 75 % de las especies utilizadas por esta etnia son nativas del Continente Americano, principalmente de México y Centroamérica (39 %, lo que sugiere que el acervo botánico básico tradicional hñähñü aún es vigente.

    Aedes albopictus is the second most important dengue virus vector in the Asian southeast after Aedes aegypti. Its entrance into the Americas occurred in 1985, and laboratory studies performed show its potential as a vector in this continent as well. In Colombia, this species has been reported in Leticia (Amazonas) in 1998 and Buenaventura (Valle del Cauca) in 2001. The latest discoveries show that this mosquito continues to advance toward the country's interior. To inform that the presence of A. albopictus is documented in the city of Cali, Valle del Cauca, Colombia. Since 2002, weekly sampling has been performed using larval traps located at seventeen stations. The identification of the A. albopictus species, was carried out in the Unidad de Entomología, Laboratorio de Salud Pública Departamental. These identifications were confirmed in the Entomology Laboratory at Universidad del Valle and the National Institute of Health in Bogotá. From April to June of 2006, larvae of A. albopictus were found in six sampling stations located between northwest and northeast of Cali, one of them in the suburban area of the Yumbo city. The control of A. aegypti and A. albopictus must be integrated into a single program. The surveillance in the cities and nearest departments must be intensified with the objective of limiting the advancement of A. albopictus.

En ellas se expresa la contradicción entre Estados que abandonan el principio de bienestar permitiendo leyes laborales que, al flexibilizar el empleo, reproducen la pobreza; mientras esos mismos Estados tratan de mitigarla con transferencias de recursos a asalariados precarios fuertemente marcados por su condición de género, etnia y nacionalidad.

La población estimada para este grupo es de 1600 habitantes (Wise, M.R. 1972 que se distribuye en 12 comunidades nativas, de las cuales la mitad están tituladas por el Estado peruano. Sobre este grupo existe regular bibliografía principalmente en lo referido a lingüística, relatos de viajeros y misioneros de diversas órdenes y en menor escala trabajos etnográficos y etno-históricos. En esta serie de artículos los autores pretenden una aproximación en detalle para profundizar el conocimiento que de esta etnia se tiene. Para ello utilizaremos los trabajos anteriores a los cuales sumaremos nuestras notas y apreciaciones recogidas durante cuatro años de trabajo en la zona. El primer artículo de L.

En dicha obra el señor Williams cataloga -entre muchas otras de distintas regiones de la Amazonia peruana-- un buen numero de plantas leñosas coleccionadas por él en la hacienda "La Victoria", muy cerca de Leticia, haciéndolas figurar como del Perú. Esto se debe a que en la época que Williams visito aquella región hoy colombiana -a mediados de 1929- no se había perfeccionado todavía, o mejor dicho, no se había puesto en práctica (aunque ya estaba promulgado solemnemente el tratado de fronteras entre Colombia y el Perú que puso fin al litigio que estos dos países sostuvieron por más de un siglo sobre una gran parte del territorio selvoso que se extiende entre los ríos Caquetá y Amazonas. Digo que no se había puesto en practica dicho tratado porque, si bien se firmó el 24 de marzo de 1922 y se promulgo el 31 de marzo de 1938, sólo vino a ejecutarse in situ el 17 de agosto de 1930, después de localizada y amojonada la frontera, mediante la formalidad del acto de entrega y de recibo de los territorios que les tocó definitivamente a un país y al otro. Fue, pues, un año después de la visita de Williams a dicha región cuando la bandera y las autoridades colombianas reemplazaron efectivamente a las peruanas en el llamado "Trapecio Amazónico", cuya población principal es Leticia, sobre el rio Amazonas.

    This work aims to bring new ideas for expanding access to electricity services to traditional communities in the state of Amazonas including strategies for income generation and improvement of local living conditions. To this end, the main achievements in the community of Roque in the implementation of the project Vegetable Oil for Electricity Generation and Valuation of Biodiversity in Isolated Communities of Extractive Reserve in the Middle Jurua, Carauari, Amazon state were identified and evaluated. Based on the results, a proposal for planning electrification works is formulated that takes into account local knowledge on socioeconomic and environmental conditions. In order to be implemented, such a proposal will require an improvement of the existing regulatory system and the establishment of partnerships or institutional articulation with broad stake holder involvement, including representatives of communities and local power utilities.

Ce travail propose d’appréhender la vulnérabilité de ces communautés riveraines aux crues et étiages extrêmes autour du Lago Janauaca, près de Manaus, dans un contexte climatique d’intensification du cycle hydrologique. Dans un premier temps nous proposons de caractériser la variabilité hydrologique du Rio Solimões et son impact spatial sur le Lago. Si l’extension du phénomène est frappante, les dynamiques anthropiques sur les rives du lac sont elles aussi importantes. Celles-ci s’expliquent plus par l’ouverture de pistes entre le lac et la BR319, que par l’expansion des cultures traditionnelles qui restent modérée. Enfin, une série d’entretiens menés auprès des riverains dévoile une relation complexe entre les différentes activités des populations et les extrêmes hydrologiques. Les sécheresses y apparaissent comme les perturbations majeures, non seulement à cause de leurs impacts sur les cultures, mais surtout en raison des difficultés qu’elles entraînent pour les mobilités locale et régionale.Intimamente relacionado com o pulso de inundação sazonal do rio Amazonas, as atividades dos agricultores e pescadores das várzeas são particularmente sensíveis aos eventos mais extremos da variabilidade hidrológica.

    This study evaluates the daily dietetic ingestion of Hg and some nutrients of pre-scholar children from eight communities of Amazonas state, Brazil. Some children from each community were selected and their diets (24 hours total consumption) were collected by the duplicate quantity method and a pool of diets composed for each of these communities. The diet samples were analysed for the Hg total content by a CV AAS linear accelerator and neutron activation analysis for determination of Ca, Fe, K, Se and Zn micro nutrients. Both analytical methodologies precision and accuracy were validated using the certified reference materials analysis. The provisional tolerable weekly ingestion (PTWI) for Hg and the daily micro nutrient ingestion were calculated for each group, considering an 10 kg average weight for each child. The obtained results for all diets were shown the inadequacy prevail for the evaluated micro nutrients, and some communities exceeded the limit of 5 μg Hg/kg of body weight (PTWI). Those results suggested that the nutritional education program must be implemented at those communities, aiming the better utilization of the local food natural resources. (author)

    Full Text Available ABSTRACTThe Pleistocene deposits exposed in the Amapá Coastal Plain (onshore portion of the Foz do Amazonas Basin, northeastern South America were previously interpreted as Miocene in age. In this work, they were named as "Itaubal Formation" and were included in the quaternary coastal history of Amazonia. The study, through facies and stratigraphic analyses in combination with optically stimulated luminescence (single and multiple aliquot regeneration, allowed interpreting this unit as Late Pleistocene tidal and fluvial deposits. The Itaubal Formation, which unconformably overlies strongly weathered basement rocks of the Guianas Shield, was subdivided into two progradational units, separated by an unconformity related to sea-level fall, here named as Lower and Upper Units. The Lower Unit yielded ages between 120,600 (± 12,000 and 70,850 (± 6,700 years BP and consists of subtidal flat, tide-influenced meandering stream and floodplain deposits, during highstand conditions. The Upper Unit spans between 69,150 (± 7,200 and 58,150 (± 6,800 years BP and is characterized by braided fluvial deposits incised in the Lower Unit, related to base-level fall; lowstand conditions remained until 23,500 (± 3,000 years BP. The studied region was likely exposed during the Last Glacial Maximum and then during Holocene, covered by tidal deposits influenced by the Amazon River.

    Blood samples were collected from 20 Hispaniolan Amazon parrots (Amazona ventralis) and were divided into tubes that contained dipotassium ethylenediaminetetraacetic acid (K2EDTA) and lithium heparin. Complete blood cell counts were determined in each sample within 2 hours of collection. The level of agreement in results was moderate for plasma protein, packed cell volume (PCV), and leukocyte, monocyte, and lymphocyte counts between the anticoagulants. Plasma protein and PCV values were significantly lower in samples with lithium heparin than in those with K2EDTA, whereas lymphocyte numbers were significantly higher in lithium heparin samples than in K2EDTA samples. The level of agreement was good for the other cell types (heterophils, eosinophils, and basophils) when comparing the different anticoagulants. The poor level of agreement between anticoagulants with the increase in thrombocyte clumping in lithium heparin samples indicates that the use of lithium heparin as anticoagulant may affect thrombocyte count. No negative effects on morphology and staining of blood cells were apparent in smears from heparin samples compared with K2EDTA samples. Within the different values compared, the limits of agreement are small enough to be confident that lithium heparin can be used for routine CBC counts in a clinical setting. The use of the same anticoagulant should be recommended to follow trends within the same patient, especially when considering plasma protein concentration, PCV, and lymphocyte count.

The results indicate that fish stock of A. gigas in the RESEX of Juruá river presents good management conditions since most of the fish caught presented commercial weight and high utilization of meat, and also the equations of weight-length relationship and Kn values can be considered as reference for A. gigas eviscerated of the studied region.

    The blue-fronted Amazon (Amazona aestiva) is a widely distributed Neotropical parrot and one of the most captured parrots in nature to supply the illegal trade of wild animals. The objectives of the present study were to analyze the genetic structure of A. aestiva to identify management units and support conservation planning and to verified if A. aestiva populations have undergone a recent bottleneck due to habitat loss and capture for the pet trade. The genetic structure was accessed by analyzing six microsatellite loci in 74 individuals of A. aestiva, including samples from the two subspecies (A. a. aestiva and A. a. xanthopteryx), from five populations: four in Brazil and one in Argentina. A significant genetic differentiation (theta = 0.007, p = 0.005) could be detected only between the most distant populations, Tocantins and Argentina, localized at the northeast and southwest limits of the sample sites, respectively. There was no evidence of inbreeding within or between populations, suggesting random mating among individuals. These results suggest a clinal distribution of genetic variability, as observed for variation in plumage color of the two A. aestiva subspecies. Bottleneck analysis did not show a recent reduction in population size. Thus, for the management and conservation of the species, the populations from Argentina and Tocantins should be considered as different management units, and the other populations from the center of the geographical distribution as another management unit.

    Information on perching-joint angles in birds is limited. Joint immobilization in a physiologic perching angle has the potential to result more often in complete restoration of limb function. We evaluated perching-joint angles in 10 healthy cockatiels (Nymphicus hollandicus), 10 Hispaniolan Amazons (Amazona ventralis), and 9 barred owls (Strix varia) and determined intra- and interobserver variability for goniometric measurements in 2 different radiographic projections. Intra- and interobserver variation was less than 7% for all stifle and intertarsal joint measurements but frequently exceeded 10% for the hip-joint measurements. Hip, stifle, and intertarsal perching angles differed significantly among cockatiels, Hispaniolan Amazon parrots, and barred owls. The accuracy of measurements performed on straight lateral radiographic projections with superimposed limbs was not consistently superior to measurements on oblique projections with a slightly rotated pelvis. Stifle and intertarsal joint angles can be measured on radiographs by different observers with acceptable variability, but intra- and interobserver variability for hip-joint-angle measurements is higher.

    The red-tailed Amazon parrot (Amazona brasiliensis) is an endangered psittacid species that is endemic in the south and southeast Brazilian Atlantic coastal region. Hematologic evaluation is important to monitor the health of these birds, and information about laboratory values for this species is scarce. Hematologic and total plasma protein profiles were determined for 33 free-living nestling parrots in Paraná state, Brazil. Parrots were temporarily removed from the nest and manually restrained to record body weight and collect blood samples. Mean body weight was 400 g in 20 birds (group 2). Significantly higher levels of mean corpuscular hemoglobin concentrations, white blood cell counts, monocytes, and basophils were observed in younger birds (group 1). A stress leukogram (high white blood cell and heterophil count) was found in all nestlings, suggesting stress induced by capture and restraint. Parameters obtained in this study will be essential to assess the physiologic and pathologic condition of wild parrots, to evaluate the effects of environmental changes on their health, and to contribute to conservation efforts of this endangered species.

    Full Text Available En la región del trapecio amazónico de Colombia, las secuencias sedimentarias recientes (neo formación dependen en su forma y en su estabilidad del ciclo anual de inundación del río Amazonas. Entre los materiales sedimentarios no afectados por el ciclo actual del río se reconoce a la terraza de Leticia-Tabatinga, de edad estimada entre 8000 y 10000 años A.P., aunque es posible que su modelado se generara en el tardiglaciar (14.000 años AP.. Sus sedimentos están recubiertos por la Formación Iça y es la más alta de las unidades geológicas que aún conservan su morfología plana original. Otros materiales sedimentados se han acumulado como depósitos de canal asociado a drenajes sobre la terraza, con una edad aproximada de alrededor de 8.600 años A.P. Los lagos asociados con cananguchales (palmares dominados por Mauritia flexuosa se reconocen sobre la terraza de Leticia y se encuentran en las áreas donde se observa erosión diferencial, fenómeno que es relativamente reciente de hace aproximadamente 530 años A.P. Entre las unidades geológicas vinculadas con las zonas inundadas por el ciclo anual del río Amazonas, figuran los sistemas lacustres de Zapatero y Yahuarcaca cuya formación se estima entre 240 años A.P. y 150 años A.P., se hallan cercadas por la terraza aluvial La Milagrosa de edad estimada en 131 años A.P., que es cubierta por el agua en épocas de niveles altos de lluvias. También se reconocen geoformas (neoformación de sistemas aluviales meándricos, como barras de arena, canales, canales de drenaje que conectan un río con otro, o un río a un lago o dos trazos de un río. Las geoformas y los materiales de neoformación son jóvenes y tienen demasiada evolución debido al modelado permanente del paisaje que está directamente relacionada con alteraciones procedentes de la intervención humana (cambio climático que influyen directamente en las dinámicas fluviales en el territorio.

    Previous provenance studies along the Amazonas river have demonstrated that the Amazon drainage basin has been reorganized since the Late Cretaceous with the uplift of the Andes and the establishment of the transcontinental Amazon fluvial system from Late Miocene to Late Pleistocene (Hoorn et al., 1995; Potter, 1997, Wesselingh et al., 2002; Figueiredo et al. 2009, Campbell et al., 2006, Nogueira et al. 2013).There is a lack of data from Eastern and Central Amazonia and only limited core data from the Continental Platform near to current Amazonas river mouth. Central Amazonia is strategic to unveil the origin of Amazonas River because it represents the region where the connection of the Solimões and Amazonas basin can be studied through time (Nogueira et al. 2013). Also, there is a shortage of information on the old Precambrian and Paleozoic sediment sources relative to Cretaceous and Miocene siliciclastic deposits of the Solimões and Amazonas basins. We collected stratigraphic data, detrital zircon U-Pb ages and Nd and Hf isotopes from Precambrian, Paleozoic, Cretaceous and Miocene siliciclastic deposits of the Northwestern border of Amazonas Basin. They are exposed in the Presidente Figueiredo region and in the scarps of Amazon River, and occur to the east of the Purus Arch. This Northwest-Southeast trending structural feature that divides the Solimões and Amazonas basin was active at various times since the Paleozoic. Detrital zircon ages for the Neoproterozoic Prosperança Formation yielded a complex signature, with different populations of Neoproterozoic (550, 630 and 800 Ma) and Paleoproterozoic to Archean sources (1.6, 2.1 and 2.6 Ga). Also Nd and Hf isotopes show two groups of TDM model ages between 1.4 to 1.53 Ga and 2.2 and 3.1 Ga. Sediments typical of Paleozoic sedimentary rocks of the Nhamundá and Manacapuru Formations revealed NdTDM model ages of 1.7, 2.2 and 2.7 Ga, but Hf isotopes and U-Pb zircon ages are more varied. They characterize a

As estratégias metodológicas utilizadas como a observação participante, análise documental, grupos focais, aplicação de questionários permitiram conhecer eventos sociopolíticos e culturais, a percepção dos indivíduos, os aspectos contextuais sócio-históricos que influenciaram a inserção da tecnologia do uso de agrotóxicos na terra indígena Xukuru e o processo produtivo agrícola. O uso de agrotóxicos na etnia está historicamente relacionado ao modelo socioeconômico introduzido com o processo de industrialização da região. Na percepção dos indígenas, o agrotóxico foi relacionado ao significado de remédio, mas também foi percebido como veneno. O uso dos produtos químicos é feito de forma intensiva e sem a utilização de equipamento de proteção individual. Os Xukuru reconhecem a influência dos agrotóxicos na saúde, mas destacam que esta prática é necessária para garantir a produção agrícola. Há necessidade de implementação de políticas públicas de promoção da saúde, objetivando oferecer aos índios Xukuru alternativas agrícolas sustentáveis que incluam a participação dos agricultores, respeitando suas tradições culturais.This study aims to understand the use of pesticides in agricultural cultivation and its relationship with indigenous health from a case study among the Xukuru from Ororuba indians, in the town of Pesqueira, Pernambuco State, Brazil.

El hecho de que ciertos colectivos de inmigrantes se hayan vinculado a actos y organizaciones terroristas ha sugerido la idea de un posible deterioro de la actitud hacia los inmigrantes por parte de la población española. Los objetivos de este trabajo fueron realizar, mediante un estudio descriptivo transversal, una comparación entre las puntuaciones obtenidas en la Escala de Actitud ante la Inmigración en una muestra accidental de 204 estudiantes de enfermería que respondieron a la escala en febrero de 2003 y abril de 2004. Los resultados obtenidos permiten concluir que la actitud hacia la inmigración en los estudiantes es significativamente más positiva en el curso 2003-04 que en el curso anterior (p<0,05, lo que se interpreta en términos de eficacia del énfasis docente en el principio de equidad hacia todos los usuarios, independientemente de su etnia o cultura.

En intercambio con los profesores que atienden el trabajo educativo, expresaron que existen estudiantes que reflejan abuso a quienes consideran inferiores prevaleciendo los casos del hombre sobre la mujer, obligándolas a tener sexo, a realizar trabajos de higiene o de cocina, a personas con orientación sexual no acorde para ellos y a practicantes de otras religiones o de otras regiones. Las acciones han sido desde maltratos leves de ofensas hasta acciones violentas con agresiones físicas. Esta situación conlleva a la necesidad de preparar a los estudiantes en el respeto a la diversidad y al derecho común, formando valores que cumplan a diario desde sus relaciones interpersonales y en sus funciones como futuros profesionales de la salud, implicando que no practiquen el maltrato y que aprendan a prevenirlo. Se utilizaron los métodos histórico-lógicos, deducción-inducción y análisis documental. Este trabajo tiene como objetivo: Proponer un conjunto de acciones que contribuya a la preparación de los profesionales de la salud en formación para la prevención del maltrato. Se desarrollará con los estudiantes de premédico y el trabajo interdisciplinar se tributará a las Ciencias Básicas con la asignatura de Pre-vención y promoción de salud.

    Full Text Available The Lead Books, far from being a purely Moorish invention of its creators and in its ideological content, have at their base Medieval Christian traditions, a Catholic theology and the religious-political problems of modem Spain. In their origin, thinkers of a pronounced counter-reform view also actively participated. In the present state of research of the Morisco problem which goes beyond the monolithic, partisan vision of this ethnic group, it is essential to initiate new fields of interpretation of the books' contents and of the findings of Sacromonte in general. As an example, we suggest a treatment of the persons and themes fundamental to the thread of argument, as are the Apostle St. James, St. Cecil and the Virgin's inmaculate conception.

    Lejos de ser sólo una fabulación netamente morisca en su inventores y en sus contenidos ideológicos, los libros plúmbeos tienen en su base las tradiciones medievales cristianas, la teología católica y la problemática político-religiosa de la España moderna; en su gestación también participaron activamente pensadores de marcado corte contrarreformista. En la línea actual de investigación del problema morisco, que supera la monolítica, partidista y radial visión de esta etnia, hay que iniciar nuevos campos de interpretación del contenido de los libros plúmbeos y de los hallazgos del Sacromonte granadino en general. Proponemos como ejemplo el tratamiento de personajes y temas tan fundamentales en el hilo argumental como son el apóstol Santiago, san Cecilio y la Concepción Inmaculada de la Virgen.

    Parrots are popular companion animals, but are frequently relinquished because of behavioral problems, including abnormal repetitive behaviors like feather damaging behavior and stereotypy. In addition to contributing to pet relinquishment, these behaviors are important as potential indicators of diminished psychological well-being. While abnormal behaviors are common in captive animals, their presence and/or severity varies between animals of the same species that are experiencing the same environmental conditions. Personality differences could contribute to this observed individual variation, as they are known risk factors for stress sensitivity and affective disorders in humans. The goal of this study was to assess the relationship between personality and the development and severity of abnormal behaviors in captive-bred orange-winged Amazon parrots (Amazona amazonica). We monitored between-individual behavioral differences in enrichment-reared parrots of known personality types before, during, and after enrichment deprivation. We predicted that parrots with higher scores for neurotic-like personality traits would be more susceptible to enrichment deprivation and develop more abnormal behaviors. Our results partially supported this hypothesis, but also showed that distinct personality dimensions were related to different forms of abnormal behavior. While neuroticism-like traits were linked to feather damaging behavior, extraversion-like traits were negatively related to stereotypic behavior. More extraverted birds showed resiliency to environmental stress, developing fewer stereotypies during enrichment deprivation and showing lower levels of these behaviors following re-enrichment. Our data, together with the results of the few studies conducted on other species, suggest that, as in humans, certain personality types render individual animals more susceptible or resilient to environmental stress. Further, this susceptibility/resiliency can have a long

    Starch gel electrophoresis was used for examining the transferrin gene locus (Tf) and two esterase gene loci (Est-1 and Est-D1) of a pirarucu (Arapaima gigas) population sample collected from Santa Cruz Lake, Tefé River, Amazonas, Brazil. The Tf locus was tentatively classified as being polymorphic, showing two double-banded patterns (Tf(12) and Tf(22)) of the three theoretically expected ones (Tf(11), Tf(12) and Tf(22)), presumably controlled by two co-dominant alleles, Tf(1) and Tf(2). The monotony detected in pirarucu Tf locus genotypes showing a very high proportion of the double-banded heterozygote pattern Tf(12) (95% of the sampled individuals) may indicate the possibility of their having come from representatives of the same brood begotten by a pair of fish, where a single-banded Tf(11) homozygote pattern male would have crossed with a single-banded Tf(22) homozygote pattern female, or vice versa. One zone of electrophoretic activity was detected in esterase, presumably controlled by a monomorphic Est-1 locus with the fixed allele Est-1(1) where all individuals showed the single-banded Est-1(11) homozygote pattern. Esterase-D also displayed one zone of electrophoretic activity, presumably controlled by a monomorphic Est-D1 locus with a fixed allele Est-D1(1) where all individuals revealed the single-banded Est-D1(11) genotype pattern. The monotony comprised by single-banded genotype patterns in both esterase systems tested may also indicate the possibility of the individuals from the sample examined having come from representatives of the same brood begotten by a pair of fish with both the male and female having the same genotypes.

    To determine the degree of agreement between 3 commercially available point-of-care blood glucose meters and a laboratory analyzer for measurement of blood glucose concentrations in Hispaniolan Amazon parrots (Amazona ventralis). 20 healthy adult Hispaniolan Amazon parrots. A 26-gauge needle and 3-mL syringe were used to obtain a blood sample (approx 0.5 mL) from a jugular vein of each parrot. Small volumes of blood (0.6 to 1.5 microL) were used to operate each of the blood glucose meters, and the remainder was placed into lithium heparin microtubes and centrifuged. Plasma was harvested and frozen at -30 degrees C. Within 5 days after collection, plasma samples were thawed and plasma glucose concentrations were measured by means of the laboratory analyzer. Agreement between pairs of blood glucose meters and between each blood glucose meter and the laboratory analyzer was evaluated by means of the Bland-Altman method, and limits of agreement (LOA) were calculated. None of the results of the 3 blood glucose meters agreed with results of the laboratory analyzer. Each point-of-care blood glucose meter underestimated the blood glucose concentration, and the degree of negative bias was not consistent (meter A bias, -94.9 mg/dL [LOA, -148.0 to -41.7 mg/dL]; meter B bias, -52 mg/dL [LOA, -107.5 to 3.5 mg/dL]; and meter C bias, -78.9 mg/dL [LOA, -137.2 to -20.6 mg/dL]). On the basis of these results, use of handheld blood glucose meters in the diagnosis or treatment of Hispaniolan Amazon parrots and other psittacines cannot be recommended.

    Birds are routinely presented to veterinarians for dehydration. Success with these cases ultimately depends on providing replacement fluids and re-establishing fluid homeostasis. Few studies have been done to determine reference ranges for plasma osmolality in birds. The goals of this study were to determine reference values for plasma osmolality in 3 species of parrots and to provide recommendations on fluid selection for replacement therapy in these species. Blood samples were collected from 21 adult Hispaniolan Amazon parrots (Amazona ventralis), 21 Congo African grey parrots (Psittacus erithacus erithacus), and 9 red-fronted macaws (Ara rubrogenys), and were placed into lithium heparin containers. Plasma osmolality was measured in duplicate with a freezing point depression osmometer. Summary statistics were computed from the average values. Reference ranges, calculated by using the robust method, were 288-324, 308-345, and 223-369 mOsm/kg in African grey parrots, Hispaniolan Amazon parrots, and red-fronted macaws, respectively. The mean +/- SD values were 306 +/- 7, 327 +/- 7, and 304 +/- 18 mOsm/kg in African grey parrots, Hispaniolan Amazon parrots, and red-fronted macaws, respectively. Comparisons with osmolality values in mammals and values previously reported for psittacine bird species suggest that plasma osmolality is slightly higher in parrots than in mammals, species-specific differences exist, and differences between reported values occur. Overall, fluids with an osmolarity close to 300-320 mOsm/L, such as Normosol-R, Plasmalyte-R, Plasmalyte-A, and NaCl 0.9%, can be recommended in parrots for fluid replacement therapy when isotonic fluids are required.

    Although abnormalities in blood glucose concentrations in avian species are not as common as they are in mammals, the inability to provide point-of-care glucose measurement likely results in underreporting and missed treatment opportunities. A veterinary glucometer that uses different optimization codes for specific groups of animals has been produced. To obtain data for a psittacine bird-specific optimization code, as well as to calculate agreement between the veterinary glucometer, a standard human glucometer, and a laboratory analyzer, blood samples were obtained from 25 Hispaniolan Amazon parrots (Amazona ventralis) in a 2-phase study. In the initial phase, blood samples were obtained from 20 parrots twice at a 2-week interval. For each sample, the packed cell volume was determined, and the blood glucose concentration was measured by the veterinary glucometer. The rest of each sample was placed into a lithium heparin microtainer tube and centrifuged, and plasma was removed and frozen at -30 degrees C. Within 5 days, tubes were thawed, and blood glucose concentrations were measured with a laboratory analyzer. The data from both procedures were used to develop a psittacine bird-specific code. For the second phase of the study, the same procedure was repeated twice at a 2-week interval in 25 birds to determine agreement between the veterinary glucometer, a standard human glucometer, and a laboratory analyzer. Neither glucometer was in good agreement with the laboratory analyzer (veterinary glucometer bias, 9.0; level of agreement, -38.1 to 56.2; standard glucometer bias, 69.4; level of agreement -17.8 to 156.7). Based on these results, the use of handheld glucometers in the diagnostic testing of Hispaniolan Amazon parrots and other psittacine birds cannot be recommended.

    Full Text Available Em seis indústrias madeireiras de Manaus, Amazonas, foi realizado um trabalho de pesquisa, com a utilização de um questionário,para averiguar as condições de uso e processamento da madeira e as medidas preventivas contra o ataque de insetos. Foram realizados, também,um levantamento da ocorrência de insetos em 19 espécies de madeiras utilizadas por essas indústrias e a avaliação do dano provocado pelas principais espécies de Coleoptera (besouros e Isoptera (cupins. Das respostas apuradas, constatou-se que nenhuma das empresas visitadas emprega qualquer produto para prevenir o ataque de insetos às toras, assim como a secagem e a estocagem das toras são feitas de forma incorreta, contribuindo para aumentar a intensidade de ataque de insetos. Foram encontradas uma família de cupins e 16 de besouros, ressaltando que destas apenas cinco causam danos à madeira. Do total de 13 espécies de insetos coletados, destacam-se Xyleborus affinis Eichhoff e Platypus parallelus (Fabricius, encontradas em 18 espécies madeireiras, sendo conseqüentemente responsáveis pela maioria dos danos nas toras X. volvulus (Fabricius e Platypus sp. foram encontradas em cinco espécies; X. ferrugineus (Fabricius em três espécies; Minthea rugicolis Walk, Minthea sp. e Nasutitermes corniger (Motschulsky em duas, e Dinoderus bifoveolatus Wollaston, Anoplotermes sp.; e Cnesinus sp. em uma.

    In 2015, three psittacines were presented within 30 days, each with differing clinical signs and patient histories. A 13-yr-old male eclectus parrot (Eclectus roratus) was presented for weakness, depression, and acute anorexia. On presentation it was determined to have a heart murmur, severely elevated white blood cell count (93.9 10 3 /μl) with a left shift (2.8 10 3 /μl bands), and anemia (30%). Severe hepatomegaly was noted on radiographs, ultrasonography, and computed tomography. A cytological sample of the liver obtained through a fine needle aspirate revealed intracellular acid-fast bacilli identified as Mycobacterium avium. A 20-yr-old female double yellow-headed Amazon parrot (Amazona oratrix) was presented for a 1-mo history of lethargy and weight loss despite a good appetite. The parrot's total white blood cell count was 16.8 10 3 /μl and the PCV was 35%. Following its death, a necropsy revealed a generalized granulomatous condition that involved the small intestines, lungs, liver, spleen, and medullary cavities of the long bones, with intracellular acid-fast bacilli identified as Mycobacterium genavense. The third case, an 18-mo-old female black-headed caique (Pionites melanocephala), was presented with a 1-day history of lethargy and depression. On presentation, the caique had a heart murmur, distended coelom, palpable thickening of the coelomic organs, and increased lung sounds. Following the caique's death, a complete necropsy revealed mycobacteriosis of the liver, spleen, small intestines, pericardial fat, and bone marrow. The infection was identified as Mycobacterium genavense. The importance of advances in Mycobacterium spp. identification, continued presence of this organism in captive avian populations, difficulty in obtaining a definitive antemortem diagnosis, and conflicting recommendations regarding treatment are thought-provoking areas of focus in this case series.

    Full Text Available Na Reserva Extrativista (RESEX do Rio Jutaí, Amazonas, os moradores têm manifestado expectativas e aspiram mudanças quanto ao manejo da andiroba (Carapa spp.. Na presente pesquisa, foram formuladas perguntas sobre as razões dessas mudanças e como elas estão acontecendo. Aspectos socioeconômicos e de manejo foram estudados em 31 unidades familiares de dez comunidades da RESEX. Utilizaram-se entrevistas semiestruturadas, observação participante e avaliação de tempo e esforço de trabalho. A população local atribuiu relevante significado para a espécie em razão do valor de uso, destacando-se as aplicações medicinais, na pesca de matrinxã (Brycon spp. e de outras quatro espécies de peixe. O manejo da andiroba é realizado, principalmente, em áreas de floresta primária e é complementado pela maioria das famílias na forma de plantios, comercializando parte da produção no interior da RESEX. Análises multivariadas discriminaram um grupo que investe maior tempo e número de pessoas na coleta, tendo maior produção, no entanto com menor rendimento. Não existe tendência à especialização das atividades, pois as famílias são pluriativas. O fenômeno estudado se encaixa na proposta conceitual do neoextrativismo, na medida em que as práticas estão em transformação e incluem cultivo e beneficiamento.

    This study evaluates the daily dietetic ingestion of Hg and some nutrients of pre-scholar children from eight communities of Amazonas state, Brazil. Some children from each community were selected and their diets (24 hours total consumption) were collected by the duplicate quantity method and a pool of diets composed for each of these communities. The diet samples were analysed for the Hg total content by a CV AAS linear accelerator and neutron activation analysis for determination of Ca, Fe, K, Se and Zn micro nutrients. Both analytical methodologies precision and accuracy were validated using the certified reference materials analysis. The provisional tolerable weekly ingestion (PTWI) for Hg and the daily micro nutrient ingestion were calculated for each group, considering an 10 kg average weight for each child. The obtained results for all diets were shown the inadequacy prevail for the evaluated micro nutrients, and some communities exceeded the limit of 5 {mu}g Hg/kg of body weight (PTWI). Those results suggested that the nutritional education program must be implemented at those communities, aiming the better utilization of the local food natural resources. (author)

    Full Text Available A member of the Lutzomyia flaviscutellata complex from Rondônia and southern Amazonas States, Brazil, is so close to the Venezuelan Lutzomyia olmeca recuta Feliciangeli et al., 1988, that it is regarded as belonging to the same species. Since this phlebotomine co-extis with L. olmeca nociva in Brazil, the subspecific status of the former is untenable and is rased to specific rank, as Lutzomyia reducta. The Brazilian material is described and illustrated, and compared with specimens of L. o. nociva and L. flaviscutellata from the same area. Keys to the known taxa of the flaviscutellata complex are presented. Leishmania amazonensis was isolated from one heavily infected specimen of L. reducta, making this the third species of the flaviscutellata complex to be implicated as a vector of this parasite in Brazil. The relative abundance of the three sympatric flaviscutellata complex species varies locally and appears to be related to soil drainage. L. reducta constituted about 25% if all phlebotomines captured in Disney traps at poorly drained and well drained site, but appears not to coloniza areas subject to periodic flooding. L. olmeca nociva was restricted to poorly drained areas not subject to flooding, whereas L. flaviscutellata was ubiquitous L. reducta has never been detected north of the Amazon river in Brazil, but absence of recosrds from western and northwestern Amazonas State may reflect lack of collecting in these areas.Um flebotomíneo do complexo Lutzomyia flaviscutellata, de Rondônia e sul do Amazonas, Brasil é tão parecido com Lutzomyia olmeca reducta, que é considerado como sendo da mesma espécie. Este flebotomíneo ocorre junto com L. olmeca nociva, portanto o nome é emendado para o nível de espécie, como Lutzomyia reducta. O material do Brasil é descrito e ilustrado, e comparado com exemplares de L. o. nociva e L. flaviscutellata da mesma área.

    Full Text Available Resumo. Foi realizado um estudo sobre artrópodes que vivem em ninhos de Columba livia Gmelin 1789, ave conhecida como pombo urbano e que nidifica em construções humanas, com o intuito de inventariar as espécies de artrópodes associadas. Foram coletados 14 ninhos de C. livia em nove bairros da área urbana de Manaus os quais foram levados ao laboratótio e colocados em um extrator do tipo Berlese-Tulgren por 12 dias, para a captura dos artrópodes. Foram encontrados 10.323 artrópodes, pertencentes a 3 subfilos, 3 classes, 14 ordens e 33famílias. Acari foi mais abundante com 7.879 indivíduos, sendo o gênero Caloglyphus Berlese, 1923, o mais representativo (75%. A maioria das espécies encontradas é detritívora. A diversidade de artrópodes foi menor em Manaus se comparada à registrada em trabalhos da região Paleártica, provavelmente por C. livia ser uma espécie exótica na fauna Neotropical. Arthropods in the nests of Columba livia Gmelin 1789 (Aves, Columbidae in the urban area of Manaus, Amazonas, Brazil. Abstract. The objective of this study was identify the arthropod fauna in nests of the urban pigeon, Columba livia Gmelin 1789 who build their nests in man-made buildings. Fourteen nests were collected in nine districts of the built up area of the city of Manaus. For twelve days, arthropods were extracted in a Berlese-Tulgren funnel. A total of 10.323 arthropods representing 3 subphyla, 3 classes, 14 orders and 33 families were detected. Acari was the most abundant group with 7879 individuals. Mites of the genus Caloglyphus Berlese, 1923, made up over 75 % of all arthropods collected. Most of the arthropods extracted are detrivorous and apterous. The diversity found in Manaus was lower than that reported for samples collected in the Palearctic Region, probably because C. livia is exotic in the Neotropical fauna. The introduction of this pigeon can be responsible for a major contact between some arthropods and humans.

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

    Full Text Available En la actualidad la sociedad está formada por individuos de diferentes religiones, etnias o culturas. Ante esta situación, la utilización de valores comunes puede ser la garantía del éxito de la convivencia. A estos valores los denominamos democráticos, porque garantizarán la eficacia en la convivencia pluralista, y en su transmisión toma un papel primordial la educación intercultural llevada a cabo en las escuelas. ¿Pero en la práctica intercultural el género del alumnado influye en la utilización de estos valores? Responder a esta cuestión es el objetivo de nuestra investigación. Este estudio, se centra en conocer la relación entre el género y la utilización de valores democráticos. Se utilizó una muestra de 493 adolescentes (48.70% mujeres, 100% blancos, Medad=13.91%, SD=0.29 pertenecientes a la ciudad de Tromsø (Noruega. Tres tipos de valores democráticos fueron evaluados (valores primarios, secundarios y terciarios. Los resultados concluyen que son las adolescentes las que más utilizan en la práctica intercultural estos tipos de valores. Además, aunque ambas muestras concuerdan en considerar al mismo valor como el que menos utilizarían en la práctica intercultural, sus preferencias difieren cuando se trata de elegir al valor que más utilizarían en dicha situación.

    Full Text Available A maior parte da produção pesqueira do Estado do Amazonas é desembarcada em Manaus, entretanto, as características de organização do apoio à produção e da comercialização neste centro, pouco têm sido avaliadas ou consideradas nas discussões para o desenvolvimento do setor. O presente trabalho visa apresentar estas características de forma a estabelecer um referencial histórico sobre a organização do desembarque pesqueiro em Manaus e para subsidiar o planejamento do setor. Entrevistas foram efetuadas com diversos atores deste setor, de forma a cobrir o mosaico de alternativas que existem para o abastecimento de pescado. Há quatro tipos de agentes de comercialização atacadista de pescado para Manaus: o barco de pesca, o despachante, o atravessador e os frigoríficos. O despachante aparece como ator central no processo produtivo pesqueiro no período, seja por financiar as viagens e operações de comercialização, ou por executar a ligação entre os produtores-pescadores e os comerciantes de pescado. Exceção a esta regra ocorre com o "pescador ribeirinho autônomo", o qual pesca com seus próprios meios e comercializa sua produção com compradores sem intermediação. No comércio varejista, os feirantes são os mais importantes, sendo a Feira da Panair responsável por cerca de 20% do abastecimento do pescado in natura em Manaus. Os supermercados e os pequenos comerciantes são os demais agentes varejistas, cuja participação na comercialização da produção era ainda pequena, porém financeiramente é maior visto que disponibilizam produtos com valor agregado e portanto preços maiores a mercados de classe média que o dos feirantes.Manaus is the main commercial center for fish prodution in the state of Amazonas.

    Full Text Available Los comportamientos correlativos de los índices cefálicos y postcefálicos en los análisis de relaciones intergrupales no han sido suficientemente explorados hasta hoy. La escasez de datos de ambos segmentos corporales ha limitado este tipo de estudios. A la vez, otras estimaciones de la "forma" mediante ajustes del "tamaño" han sido propuestas, dándose por sentada su superioridad al uso de los índices. En este ensayo se analizan la correspondencia entre formas y la eficiencia discriminante de los índices, aprovechando los datos de la colección Vellard que comprende 1734 aborígenes provenientes de 12 grupos étnicos del Gran Chaco Sudamericano. Se empleó para ello el Análisis de Homogeneidad (HOMALS, mediante el cual se calcularon los vectores propios y los "pesos" tanto de las variables (índices cuanto de los grupos en las dimensiones principales de la variación, representando gráficamente su ubicación en el sistema coordenado de las mismas. Los resultados muestran similares relaciones entre las formas de la cabeza en hombres y en mujeres, pero en éstas hay una neta independencia entre las categorías de la porción neural y las de la facial. La mayor diferenciación morfológica de los chaquenses se registra en esas regiones cefálicas, mientras que a nivel del segmento postcefálico las etnias son más semejantes. Las relaciones morfológicas interétnicas son diferentes según el sexo considerado. En el interior de cada sexo, la topología obtenida es idéntica ya se tome en cuenta solamente la cabeza o ésta conjuntamente con el cuerpo.

Seventeen species are recorded from Brazil, but only O. elegantula Young, 1977, O. insipida Young, 1977, and O. jurua Young, 1977 are recorded from Amazonas State. Oragua partitula (Jacobi, 1905) is herein firstly recorded from Brazil, ocurring in Amazonas State. The aim of the study was to describe eight new species of Oragua, to provide a key to males of the species of the genus that are recorded from Amazonas State and to study in detail the female terminalia of these new species. Also, the female of O. jurua Young, 1977 is herein described for the first time. Oragua alerochae sp. nov. has the external color pattern similar to O. bifasciata Cavichioli, 2000, however, the head is darker, the forewings are paler and the stripes are thinner, aedeagus is much more curved with long apical processes, and apex of paraphyses rami are curved. Oragua aurantimaculata sp. nov. is similar externally to O. elegantula and Oragua jau sp. nov. as they share the body brown with three orange maculae on crown and orange maculae on forewings, but it has the aedeagus with shaft enlarged medially with a pair of apical processes curved anteriorly and connective more slender. Oragua bella sp. nov. is dark with orange spots, aedeagus with basal elongated processes extending to the apex of the pygofer, with the basal portion enlarged and narrowing toward the apex. Oragua copiosa sp. nov. is dark with small pale dots all over the body, paraphyses rami are slender and their apices expanded, and styles with hooked apex, extending posteriorly beyond the connective apex. Oragua gracilenta sp. nov. has the external color similar to O. galerula, but it can be distinguished by the brown ground color, absence of two maculae near median line just before posterior margin on pronotum and apex of rami of paraphyses bifurcate and not truncate.

    Full Text Available The article analyzes the reports generated by physicians participating in the Comissão de Linhas Telegráficas Estratégicas de Mato Grosso ao Amazonas (CLTEMTA, or Rondon Commission, that labored in these states between 1907 and 1915. The commission had as its objective the construction of telegraph lines to the borders of Brazil with Bolivia and Peru. The construction activity was also accompanied by scientific studies for the 'productive occupation' of the region and by the writing of medical assessments of the region. These assessments of the so called 'northwest hinterlands' (sertões highlighted the region's unhealthy climate and the debilitating impact of malaria. The purpose is to analyze the impact of this disease in the works of the CLTEMTA. Our hypothesis is that one of its main effects was the elaboration of medical studies more and more detailed about the possible causes of diseases in that region.

    Full Text Available In order to understand the emergence and permanence of the Amazonian cities in the area corresponding to the present state of Amazonas, it was necessary to describe the political and economic facts that led to the disappearance of towns and villages or their spatialisation. The methodology is based on the investigative and descriptive analysis of primary documents. It seeks to reconstruct Tefe's geo-history and its spatiality from Vila to the city. The results show that in the mid-nineteenth century the events related to the elevation of the Amazon to the Province in 1850, the creation of the Comarca of Solimões in 1853 with headquarters in Ega, the introduction of steam navigation and the installation of new institutions to house the apparatus Legal-administrative, transplanted of the Capital. They created the conditions for the improvement of the infrastructure of the village and were conditions to elevate it to the condition of city.

    Full Text Available Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

Estudio desarrollado a sabiendas de la importancia que reviste el sistema electoral como un medio que permite a los ciudadanos convertir su voto expresado en las urnas en escaños a favor de determinado candidato o partido. En dicho análisis tomamos en cuenta la evolución constitucional del sistema electoral mexicano, la participación de las fuerzas minoritarias en la integración del Senado y de la Cámara de Diputados, la división que se hace del territorio en circunscripciones electorales, la barrera electoral que se fija a los partidos políticos para acceder a la representación en el Parlamento, la fórmula de asignación que se aplica a la votación obtenida, para finalmente concluir que el sistema electoral mexicano es esencialmente mayoritario aun cuando se vista de proporcional.

    Full Text Available La segunda administración del presidente Alan García Pérez está por concluir, y en ella se aplicaron políticas económicas acordes con el clima neoliberal que caracteriza, salvo excepciones, al conjunto de la región. En ese sentido, fueron diametralmente opuestas a las implementadas en su primer gobierno, entre 1985 y 1990, como resultado de su convicción de que bastaría un giro de 180 grados para evitar el desastre que preparó el camino a la dictadura de Fujimori. Y si bien el Perú de hoy está lejos de ser el paria planetario y de la hiperinflación, que fue el legado de su primer gobierno, como lo evidencian las notables tasas de crecimiento que hasta hace poco tuvo la economía peruana, es importante subrayar que ese desempeño fue el resultado de fuerzas que escapan del control del gobierno, como la altísima demanda de las commodities requeridas por mercados enormes como los de China e India. Ese espectacular crecimiento, frenado por la crisis reciente, no obstante, no se condice con la pobreza y la miseria en la que aún están sumergidos enormes sectores de la población urbana y, sobre todo, rural del país. Más aún, ese tipo de política, justificada por el propio presidente en sendos artículos publicados en El Comercio —como signo de los nuevos tiempos, el opositor más encarnizado del apra auroral, bajo el título de El perro del hortelano—, despertó la abierta oposición de la población nativa del Amazonas, por la amenaza que representaba su implementación para sus condiciones de vida y de reproducción

    La doctora MarthaLucía Tamayo comparte muchas inquietudes alrededor del Libro del Almismo, el Libro del Pensar; de dónde salió ese nombre; de juntar en medicina y en genética a tres escritores como lo son Jorge Luis Borges, Macedonio Fernández y Julio Cortázar. Su conferencia dice así:

    El término almismo fue ideado por Macedonio Fernández porque defendía mucho el ensimismamiento y el pensamiento hacia el interior, mirar hacia adentro; cada uno somos un “sí mismo” que nos hace diferentes aunque al mismo tiempo podemos ser iguales. Todos tenemos esa parte interior que la medicina debe trabajar y que no puede olvidar.

    “El Libro del Almismo, el libro del pensar” nos lleva a replantear y a repensar un poco la medicina que queremos, una medicina vuelta a pensar.

    Quiero contarles la historia de cómo se llegó a este libro y por qué y para qué se sigue trabajando en estos temas: Después de mi internado y de un trabajo un poco triste de rural, volví al Instituto de Genética y a la Universidad Javeriana en donde encontré al doctor Bernal y un espacio que estaba buscando para esa medicina diferente que quería, con un grupo de personas que me permitía no sólo ver la medicina sino ver muchas otras cosas más; había espacio para la literatura, para Mafalda, para hablar de niños, de locos, había incluso tiempo para hablar de medicina dentro del golf, de carros antiguos y de todo eso fui aprendiendo.

    Eso era lo que estaba buscando. Una medicina que diera espacios diferentes, que fuera más humanizada. Rápidamente me ubiqué y me quedé! No me arrepiento en lo absoluto de haberme quedado porque fue, ha sido y sigue siendo, una experiencia enriquecedora, de muchas vivencias importantes. Sabía exactamente dónde estaba y sabía que había que seguir rápido y había que trabajar muchos aspectos de esa medicina que estábamos buscando y de esa genética especial.

Se examina la competitividad del Valle en relación con Colombia y con el resto del mundo. Se cuestiona la insistencia en una estrategia exportadora como dinamizadora del desarrollo económico. Se identifica que una gran parte de la población está excluida de los beneficios del desarrollo económico. Para construir un modelo de desarrollo que incluya a esta población se recomienda recuperar la senda de la industrialización, invertir en el capital humano (educación de alta calidad, salud, salubridad y nutrición, e invertir en infraestructura. La participación del Estado en estas inversiones sociales es necesaria para disminuir la desigualdad y aumentar el crecimiento económico.

MÉTODOS: Foram realizadas viagens à aldeia Lalima em Miranda-MS, nos meses de janeiro e fevereiro de 2005. As viagens para realizar os exames só foram iniciadas após o projeto ter sido avaliado e aprovado pelos Comitê de Ética e Pesquisa da UFMS, Comitê Nacional de Ética e Pesquisa, Fundação Nacional do Índio e do cacique da aldeia Lalima. O teste HRR foi aplicado em 226 índios após terem sido submetidos a exame oftalmológico para detecção de anormalidades que pudessem comprometer a aplicabilidade do teste. O teste foi realizado sob luz natural, em dias ensolarados, sem incidência direta de sol. O teste foi aplicado e interpretado pelo mesmo examinador em todos os índios. RESULTADOS: Realizaram-se 226 exames (60,1% de uma população de 376 homens entre 10 e 45 anos de idade, que vivem na Aldeia Lalima. Não foi encontrado nenhum caso de discromatopsia na população examinada com o teste HRR. CONCLUSÃO: O resultado do presente estudo mostra a baixa prevalência de discromatopsia nesta população indígena de etnia Terena, uma vez que não se detectou nenhum caso de discromatopsia na população estudada, sendo a prevalência de discromatopsia entre homens caucasianos de 6 a 8%. A ausência de discromatopsia na população estudada, no entanto, deve ser mais bem avaliada tentando aumentar o tamanho da amostra, utilização de outros testes e, principalmente, por estudos genéticos para verificar os genes codificadores dos fotopigmentos para melhor compreensão das condições relacionadas à visão de cores dessa comunidade indígena.PURPOSE: to evaluate the frequency of dyschromatopsias among the 10 to 45-year-old male Indian population of Lalima village, Terena ethnicity, in Miranda-MS, using

    Full Text Available Se presentan los resultados de una investigación etnobotánica que trata los tintes vegetales y fúngicos entre los indígenas wichí del Chaco Semiárido. Se realizaron trabajos de campo con informantes calificados y ocasionales de ambos sexos en localidades de las provincias argentinas de Salta y Formosa. Asimismo, se hizo una revisión minuciosa de la bibliografía vinculada con el tema. Se encontraron 24 especies de plantas y 2 de hongos que son usadas para colorear productos textiles realizados a partir de fibras de cháguar (Bromelia hieronymi y B. urbaniana. Se proporcionan informaciones y detalles sobre los nombres vernáculos de las especies, las partes usadas, los procedimientos de tinción y los colores logrados. El número total de plantas tintóreas encontrado es alto comparado con los que fueron citados para otras etnias chaquenses y se registraron especies que antes no fueron mencionadas como tintóreas entre los wichís.Dye plants and fungi among the Wichí people of the Gran Chaco. This paper presents the results of an ethnobotanical investigation into plant and fungal dyes used by the Wichí people of the Semiarid Chaco. Fieldwork was carried out with occasional and key informants, both men and women, in several locations of Salta and Formosa provinces in Argentina. Moreover, a detailed examination of the bibliography on the topic was conducted. Twenty-four plant species and two fungi that are used for coloring textile products made from cháguar fibers (Bromelia hieronymi and B. urbaniana were found. Information and details on the vernacular names of the species, the parts that are used, the dying technique and the colors obtained are provided. The total number of dye plants found is high compared with the ones cited among other Chaco ethnic groups, and records were made of species that had not previously been mentioned among the Wichí people as being used for dyes.

    Full Text Available A partir de un texto del poeta Octavio Paz llamado «La imagen», se busca proseguir la equivalencia entre las imágenes de la poesía y la función que ellas tienen para el poeta, y el fantasma fundamental y su función para el analizante que está en el momento del pase. Se parte de la idea de que la poesía busca entrar en el ser así como el psicoanálisis tiene como finalidad apuntar al corazón del ser del sujeto. Se hace entonces una distinción del concepto de «ser» para el psicoanálisis, haciendo alusión también al discurso de la filosofía. Esclarecido el sentido de lo que es el «ser» para el psicoanálisis, se aborda de lleno – entre otras cosas, relacionadas con la experiencia del pase específicamente- la equivalencia entre la definición que hace Octavio Paz de «La Imagen» y el momento del pase en el análisis de un sujeto, imagen que, al igual que el mito para la filosofía, las leyes para la ciencia y el matema para el psicoanálisis, se constituyen en los instrumentos con los que cada una de estas disciplinas horadan en lo real.

    impulsions de El Niño. Les régions du centre du Brésil semblent aussi ne pas dépendre du phénomène. Durant les années classées comme normales, on n’observe pas de dépendance des contrôles climatiques qui agissent au cours des phases extrêmes de l’Oscillation du Sud. Ceci montre que l’on doit approfondir l’étude des autres causes de variation de la circulation tropicale responsables des anomalies de précipitation. Las fases altas de ENSO, El Niño (EN, y las fases bajas, Anti-Niño (AN, se relacionan diferentemente con los regímenes de lluvias en América del Sur. Para establecer el carácter de estas relaciones, se ha analizado la precipitación anual de estaciones típicas, considerando tres subpoblaciones: totales anuales de años EN, totales de años AN, y el resto o años “normales”. Precediendo a veranos australes con fenómenos EN, la precipitación invernal en Chile Central y los Andes de Argentina es abundante. Durante los veranos con episodios EN en el Pacífico tropical, suelen afectar sequías el Noreste de Brasil especialmente en el otoño o verano precedente. De diciembre a marzo de años EN, llueve copiosamente a lo largo de la costa oeste de América del Sur comprendida entre la Bahía de Tumaco y Pacasmayo. En el interior de la Sierra y el Altiplano peruano boliviano tienen lugar sequías. En las tierras bajas de Bolivia, Paraguay, y el sureste de Brasil hay fuertes lluvias anormales durante el verano y otoño austral. En medio del otoño hay precipitaciones intensas en las tierras bajas del Río de la Plata y el sur de Brasil. El segmento norte y la cuenca inferior del Amazonas tienen menos pluviosidad durante EN y niveles mayores durante AN. La cuenca interior del Amazonas reacciona inversamente, ya que tiene pluviosidad excesiva durante algunos EN. Las regiones de Venezuela y Colombia bajo la influencia del Caribe y el Atlántico experimentan anomalías negativas de lluvias durante EN y alta pluviosidad en AN. Algunas regiones de la

    Full Text Available Amazona vinacea (Kuhl, 1820 é uma espécie endêmica da Mata Atlântica e ameaçada de extinção no Brasil e no mundo. Não existem relatos recentes de sua presença na porção setentrional de sua distribuição ao norte do estado do Rio de Janeiro. O último é datado provavelmente de 1991, tendo sido considerado extinto ao norte do Espírito Santo. O presente trabalho noticia a redescoberta da espécie em Alto Rio Novo, noroeste do Espírito Santo, divisa com Minas Gerais. Foram registrados bandos em duas localidades em dezembro de 2005, sendo o maior deles composto por 28 indivíduos. Durante os registros foi observado A. vinacea se alimentando de Anadenanthera sp. (Fabaceae: Mimosoideae, uma nova fonte alimentar para a espécie. Os registros históricos mais recentes para a região citam localidades com distância inferior a 35 km dos atuais registros, reforçando a importância local. No entanto, a degradação ambiental e a captura ilegal representam obstáculos à conservação da espécie nesta região. Em dezembro de 2002 foi criado o Parque Nacional dos Pontões Capixabas, primeira Unidade de Conservação na porção serrana do norte do Espírito Santo. Uma das áreas históricas da espécie está incluída em seus limites e um dos locais onde foi agora redescoberto fica a cerca de 10 km de distância da borda do parque. Essa Unidade de Conservação é essencial à proteção de trechos nativos da Mata Atlântica e conseqüentemente do papagaio-de-peito-roxo. Além de medidas conservacionistas, a aquisição de informações sobre as populações de A. vinacea no noroeste do Espírito Santo e leste de Minas Gerais torna-se indispensável para a proposição de medidas de manejo capazes de reverter o grave quadro atual, objetivando viabilizar a permanência de populações na região mais setentrional da distribuição conhecida atualmente para a espécie.Endemic of the Atlantic Forest, Amazona vinacea (Kuhl, 1820 is listed as

    Full Text Available El más reciente debate en torno al postrabajo transforma la herencia de los dos ciclos que le precedieron desde los años setenta. El primero se correspondía con la crítica de la división social y técnica de labores informada por una filosofía de la alienación o bien por una rectificación de la arquitectónica marxista pero salvaguardando la promesa laborista del buen trabajo. El segundo ciclo hacía eco del rechazo a las cadenas de montaje fordistas y se abría al horizonte de la abolición del trabajo salarial, manteniendo sin embargo el abolengo del sujeto unitario de la historia. La presente escena asume una densidad mayor, producto del encuentro entre las nuevas tecnologías informacionales, las discusiones en el ámbito de la sociología y la antropología, de la tecnología y la ciencia, junto al dueto que inaugura el posmodernismo.

    Full Text Available El trabajo señala la necesidad de reconstruir la Universidad, dado el dinamismo que muestra la ciencia y la sociedad, pues trae consigo cambios sustanciales en la visión del mundo y en el aumento del poder del hombre sobre la naturaleza. Se analizan los supuestos epistemológicos de la universidad tradicional y se propone una nueva explicación del conocimiento humano, enfatizando el conocimiento científico. Postula una docencia fundada en las propiedades de la ciencia, cuyo método inductivo basado en los paradigmas vigentes: analítico, crítico, pragmático, ofrece una herramienta para la docencia, la investigación y la difusión de la cultura. Se propone una educación centrada en el sujeto que se hace a sí mismo (etopoiética y que insiste en el proceso de auto-creación del individuo y de la sociedad.
