    Full Text Available The foot is one of the most susceptible areas to get injured in flamenco dancing, due to footwork, characteristics of footwear and heel height. The aim of this article is to analyze the execution of high speed footwork in foot and/or ankle instability for determining differences regarding dance shoes. Ten professional flamenco dancers have taken part in this investigation, 5 female dancers (29,6+4,7 years, 55+3,5 kg, 163,8+7,3 cm and 5 male dancers (25,2+1,30 years, 61,4+7,2 kg, 171+3,1 cm. The participants had to repeat a dancing sequence consisting of 6 footworks for 15 s. This taping combined 4 different techniques. This sequence was repeated with both feet as many times as possible. The amount of footworks realized have been measured (female 171,2+7,40; male 180,6+11,8 as well as the percentage of cases carried out with ankle instability (female 9,2+1,3%; male 26,1+9,1%. Despite the female dance shoe has a higher heel, which is more associated to skin, toe and structural foot injuries, it is more stable than the flamenco boot. This is due to the necessary boot looseness to be put on/off, which causes a worse foot stability and more imbalance situations during the footwork.El pie es una de las zonas más susceptibles de lesión en el baile flamenco debido al gesto de zapateado, características del calzado y altura del tacón. El objetivo de este artículo es observar la ejecución de zapateados en situación de inestabilidad del pie y/o tobillo, para determinar diferencias en función del calzado de baile. Han participado en el estudio 10 profesionales de baile flamenco, 5 bailaoras (29,6+4,7 años, 55+3,5 kg, 163,8+7,3 cm y 5 bailaores (25,2+1,30 años, 61,4+7,2 kg, 171+3,1 cm. Los participantes debían repetir durante 15 s una secuencia de baile de 6 zapateados, que combinaban 4 gestos técnicos. Esta secuencia se repetía con ambos pies el mayor número de veces posible.

    Full Text Available A pesar de diversas publicaciones existentes sobre el colgajo mediano plantar tradicional, los colgajos de las perforantes del pie no están suficientemente estudiados. Es necesario ampliar nuestros conocimientos sobre la anatomía vascular de esta región, los problemas que pueden surgir durante la disección de la zona y las posibles soluciones. Realizamos disección anatómica de 10 pies de cadáver utilizando relleno vascular con látex coloreado. Definimos la secuencia de la disección de las perforantes de la arteria plantar medial. Medimos los puntos de salida de las perforantes dominantes en relación con 3 puntos de referencia, diámetro y longitud de cada perforante. Evaluamos la utilidad de cada colgajo para su uso en reconstrucción local o a distancia en función del diámetro y la longitud de la perforante, grosor del colgajo y morbilidad de la zona donante. Los colgajos de los vasos perforantes del pie son una buena opción para la reconstrucción tanto local como a distancia, con una mínima morbilidad de la zona donante y con un buen resultado funcional gracias a las características del tejido del pie cuando se usa para reconstrucción en mano.Traditional medial plantar flap is widely described in the literature, but foot perforator flap is a relatively new subject which still needs more detailed anatomical investigation. We need to amplify our knowledge about this surgically challenging region, dissection difficulties and possible solutions. We performed anatomical dissection on 10 cadaver feet with dyed latex intravascular injection and then dissected out the perforators arising from the medial plantar artery. We measured the origin of the dominant perforators in relationship to 3 reference points, diameter and length of each perforator. We analyzed the application of flaps based on these perforators as local and free flaps in relation to pedicle length and diameter, flap thickness and donor site morbidity. Foot perforator

    Francisco Lengua

    2010-01-01

    Full Text Available Contexto: La primera idea que tuvieron los cirujanos (1902 para evitar amputaciones por isquemia fue la de desviar el flujo arterial al sistema venoso por intermedio de una fístula arteriovenosa entre vasos adyacentes, pero con resultados inciertos. Desde entonces se han inventado las simpatecomias, las endarteriectomias y los injertos puentes o bypass y, últimamente, otros avances médicos, quirúrgicos y endovasculares. Sin embargo, en el mundo se siguen haciendo amputaciones, sobre todo en diabéticos. La arterialización de las venas del pie, basada en la vieja idea de la circulación invertida, constituye una esperanza más para estos pacientes ya condenados a la pérdida del miembro. Objetivo: Demostrar que la arterialización de las venas del pie en diabéticos con lesiones neuroisquémicas, generalmente infectadas (pie diabético, es un método eficaz y durable, aunque el puente solo funcione temporalmente. Pacientes y método: De enero de 2000 a febrero de 2009, 59 pacientes con pie diabético fueron tratados por arterialización de las venas del pie. Un deceso precoz no ha sido contabilizado. De los 58 pacientes restantes, 44 fueron hombres y 14 mujeres, con edad promedio de 71 años: (53-91 años, 54 en estado IV de Fontaine y cuatro en estado IIIB. La arterialización fue hecha con un injerto venoso invertido anastomosado, proximalmente en una arteria con buen flujo (ilíaca externa, femorales o poplítea distalmente en la vena marginal interna del pie, con destrucción de las válvulas de las venas del dorso. Resultados: De los 58 arterializados, 12 fueron fracasos por trombosis precoz, siendo amputados, y 46 fueron éxitos (79%: seis de corto, 12 de mediano y 28 de largo plazo. En los grupos que se ajustan a la definición de éxito (dos hubo 38 trombosis tardías del puente (95% y cuatro recidivas de la sintomatología isquémica.

    2015-12-01

    Full Text Available El linfedema se define como la retención intersticial de líquido hiperprotéico. En su fase incial es reversible; pero en fases más avanzadas desencadena múltiples reacciones locales que culminan en un aumento del volumen de las extremidades, hipertrofia y fibrosis de los tejidos más superficiales. El tratamiento quirúrgico del linfedema secundario crónico es idéntico cualquiera que sea su etiología, pero difiere según el estadío de la enfermedad. En los estadíos iniciales el tratamiento conservador es la primera elección; pero ante el fallo de las medidas conservadoras, el tratamiento microquirúrgico mediante anastomosis linfático-venosas y linfo-linfáticas es el que se acepta como de primera línea y proporciona excelentes resultados. En fases más tardías, las técnicas de escisión radical, más especificamente la técnica de Charles asociada o no a medidas fisiológicas, juegan un papel importante en la resolución del linfedema dada la necesidad de conseguir una redución volumétrica del miembro afectado. Con la presentación de un caso clínico, pretendemos demostrar la utilidad de la técnica de Charles en el tratamiento del linfedema secundario crónico avanzado del dorso del pie.

    A close relationship exists between the advancement of face recognition algorithms and the availability of face databases varying factors that affect facial appearance in a controlled manner. The CMU PIE database has been very influential in advancing research in face recognition across pose and illumination. Despite its success the PIE database has several shortcomings: a limited number of subjects, single recording session and only few expressions captured. To address these issues we collected the CMU Multi-PIE database. It contains 337 subjects, imaged under 15 view points and 19 illumination conditions in up to four recording sessions. In this paper we introduce the database and describe the recording procedure. We furthermore present results from baseline experiments using PCA and LDA classifiers to highlight similarities and differences between PIE and Multi-PIE.

La transferencia microquirúrgica de un dedo del pie es una de las técnicas frecuentemente empleadas. Dicho procedimiento está indicado cuando las demás opciones reconstructivas se muestran inútiles para la reparación de la pinza manual. En este trabajo se expone el caso de un varón de 32 años que acude a urgencias tras sufrir un accidente de tráfico en el que presenta traumatismo grave de la mano izquierda (mano catastrófica, entre otras policontusiones. Se interviene de urgencia preservando las máximas estructuras viables, quedando como resultado una mano con 1º, 4º y 5º dedos funcionales. Como la función de la pinza entre 1º y 4º ó 5º dedos no es plenamente satisfactoria, se optó por la reconstrucción del 3er dedo de la mano con la transferencia del 2º dedo del pie ipsilateral. Se realizaron estudios preoperatorios, como el angio-TC, para determinar la vascularización del colgajo y, posteriormente, la intervención microquirúrgica, que fue exitosa. En la actualidad, tras una adecuada rehabilitación, el paciente ha recuperado en la mano intervenida la función de pinza gruesa y fina de manera satisfactoria. La transferencia de los dedos del pie a la mano se muestra como un tratamiento eficaz para la reconstrucción de los dedos amputados y consecuentemente la función de la pinza. La rehabilitación es imprescindible para conseguir una completa funcionalidad.The correct reconstruction of the catastrophic hand requires complex surgical techniques.

    Full Text Available Casi la mitad de las fotografías publicadas en los periódicos diarios de Chile (el 41,3 por ciento no van acompañadas de leyenda o pie de foto. Es la conclusión más evidente del estudio realizado durante 2010 sobre 11 cabeceras del país sudamericano que analiza 849 entradas y que también concluye que el texto que se construye junto a la fotografía relata aspectos muy básicos de esta imagen y en muy pocas oportunidades éste entrega cantidad y calidad de información. Así mismo, los datos revelan que las escasas líneas de este elemento informativo de primera magnitud no suponen un trabajo creativo que cumpla el rol de atraer al lector, ni tampoco el de ser una atractiva entrada hacia la historia periodística.

    Full Text Available Fundament: Diabetes Mellitus is a disease of high and increasing prevalence and its complications follow a parallel course. Its morbidity is derived from its own complications which are produced at a long or short term and peripheral vascular disease hihglights among them.Objective: to check the usefulness of the anterior and posterior blockade of the tibia for the surgery of the diabetic foot. Method: Prospective study carried out from January to December 2003 at the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ to patients who are carriers of a diabetic foot and who were initially assisted at the service of Angiology and later at the service of Anesthesiology when the surgical procedures were decided. All the patients were applied an anterior and posterior blockade of the tibial nerve . The variables measured were: age, weight, height, surgical time, type of surgery, cardiac frequency medium arterial pressure, and classification of patients according to the American Association of Anesthesiology All the patients were applied a scale for assessing pain in three different moments.Result: There was a predominance of females . The blockade of the posterior tibial nerve with lidocaine 1 % in different points permitted the performance of the surgical techniques proposed. The anesthetic procedure was favorable, and economic since the patients did not requiere of the use of analgesic in the post operatory stage.

    Fundamento:La diabetes mellitus es una enfermedad de prevalencia alta y creciente, y sus complicaciones siguen un curso paralelo. Su morbilidad se deriva de las propias complicaciones que se producen a mediano y largo plazo, entre las que se destaca la enfermedad vascular periférica. Objetivo: Comprobar la utilidad del bloqueo tibial anterior y posterior para la cirugía del pie

    Full Text Available El dolor patelofemoral es uno de los desórdenes más comunes que afectan a la rodilla. De las lesiones descritas en el baile flamenco profesional, destacan las relacionadas con el pie y la rodilla, en relación al microtraumatismo repetido del gesto técnico del zapateado y a la flexión de rodilla mantenida que requiere. El objetivo de este estudio es determinar la presencia de dolor patelo femoral en profesionales del baile de flamenco y comprobar si existe relación alguna con el pie pronador y genus valgo. En el estudio han participado 46 profesionales del baile flamenco, 38 bailaoras y 8 bailaores, con una carga media de 25.4 ± 8.25 horas de baile semanales. El 34.78% de los participantes presentaban dolor patelofemoral. El 24% presentaba también genus valgo. Se encontró un 34.78% de pies pronadores. La asociación de pies pronadores y genus valgo fue del 31.25%, mientras que la asociación de pies pronadores y dolor patelofemoral fue de 43.75 % de los casos. Factores predisponentes de esta patología se dan en la práctica del baile flamenco: el impacto repetitivo, una posición mantenida y forzada de la rodilla en un rango concreto, desplazamientos y los giros bruscos. Como conclusión, se demuestra relación directa entre la presencia de pies pronadores y dolor patelofemoral en el baile flamenco. Así como entre pies pronadores y genus valgo. Estudios científicos actuales demuestran la utilidad de soportes plantares en este síndrome. La incidencia de pies pronadores y dolor patelofemoral hace recomendable estudios biomecánicos y podológicos y el uso de soportes plantares personalizados en cada caso.

    Full Text Available Se realizaron varias pruebas piloto con sísmica de reflexión de baja profundidad en depósitos de abanicos aluviales distales en la provincia de Salta, Argentina. Las pruebas incluyen dos áreas con características de subsuelo contrastantes. En el sector nororiental de la provincia, los depósitos del extenso abanico aluvial del Bermejo son arenosos y macizos, casi sin intercalaciones arcillosas; la napa se encontraba a más de 40 m de profundidad al tiempo del estudio. La otra zona de prueba se ubica al sur de la ciudad de Salta, donde coalescen abanicos aluviales pequeños que rellenan el valle de Lerma con depósitos de arena y grava, los cuales en los tramos distales se interdigitan con potentes capas arcillosas; la napa en esta área se hallaba a una profundidad mayor de 20 m al momento del estudio. La operación sísmica empleó un sismógrafo Geometrics R24 con 24 canales activos que se aumentaron a 48 mediante un "roll-over switch", alcanzando un máximo de cobertura de 1200%. Se probaron dos fuentes de sonido: una masa de 5 kg y una escopeta calibre 12. Principalmente por razones operativas se eligió como fuente la masa. Las pruebas en el abanico del Bermejo dieron registros de baja calidad, probablemente debido a la rápida pérdida de energía en las areas poco consolidadas y secas. Localmente, sin embargo, pudieron distinguirse tres unidades sísmicas y el techo del Terciario posiblemente fue detectado. Las pruebas en eje del valle de Lerma dieron registros sísmicos de excelente calidad. Se distinguieron cuatro unidades sísmicas. Un reflector débil a aproximadamente 220 mseg coincide con un cambio de las velocidades a unos 2500 m/seg y puede corresponder con el techo del sustrato terciario. Una potente capa de arcilla a una profundidad de 25 a 50 m puede claramente mapearse como un acuitardo. Los resultados de este estudio piloto demuestran que la sísmica de reflexión de poca profundidad puede ser aplicada con provecho en el

    Full Text Available RESUMEN: Sorprendente y, en cierto modo, desalentador resulta para el historiador actual el ejercicio de reconstruir la imagen que ofrecía Salamanca hace apenas un siglo. Comprobar que, a finales de la centuria pasada, en sus dos últimas décadas, el plano urbanístico de la ciudad conservaba, casi en su integridad, los mismos trazos que en los dos siglos anteriores, sin duda provocará asombro y, de alguna manera, añoranza al ciudadano que hoy se lamenta del deterioro urbano de la Salamanca presente. Pero esta extrañeza adquiere rasgos de desconcierto ante la constatación de que la erosión urbanística que soporta en la actualidad es fruto exclusivo de este siglo y no un saldo negativo que deba consignarse en la lista de pérdidas que las centurias pretéritas nos han legado como herencia. Hacia los años ochenta del XIX, una población de algo más de 22.000 habitantes vivía —según expresión de Sánchez Estevan— en «una ciudad cerrada (... por murallas ». Fuera de ellas, apenas nada, sólo campo, dominio que se veía reducido por la presencia de algunos arrabales que servían, en realidad, para destacar aún más la insularidad urbana de Salamanca como centro del espacio rural que la ahogaba.

Estudios cualitativos apuntan a una ‘ciudad dual’: concentraciones de pequeños locales en entornos densos y accesibles a pie y en transporte público, frente a grandes superficies como enclaves periféricos accesibles sólo en vehículo privado. Se polariza la discusión sin matizar la distinción entre aspectos locales del entorno (como la densidad con otros que dependen de la posición metropolitana (como la accesibilidad.El objetivo de este trabajo es distinguir y cuantificar los factores urbanos asociados más intensamente con la concentración de establecimientos y con su evolución más reciente.

  10. On semiflexible, flexible and pie algebras

    CERN Document Server

    2011-01-01

    We introduce the notion of pie algebra for a 2-monad, these bearing the same relationship to the flexible and semiflexible algebras as pie limits do to flexible and semiflexible ones. We see that in many cases, the pie algebras are precisely those "free at the level of objects" in a suitable sense; so that, for instance, a strict monoidal category is pie just when its underlying monoid of objects is free. Pie algebras are contrasted with flexible and semiflexible algebras via a series of characterisations of each class; particular attention is paid to the case of pie, flexible and semiflexible weights, these being characterised in terms of the behaviour of the corresponding weighted limit functors.

The Lower Jurassic volcanics were deposited on a regional erosion surface affecting the Permian rocks. In the studied area there is no record of Middle to Upper Triassic volcanics as in other areas of the basin. Exotic zircon crystals gave ages of Mesoproterozoic, Middle Cambian, Early Devonian and Early Carboniferous, suggesting a poliphasic basement. Chemical analyses of three selected samples show a calc-alkaline signature, supporting the existence of a volcanic arc at the Early Jurassic as it has been proposed for the center of the basin.Se dan nuevas edades U/Pb en cristales únicos de circón de muestras de corona de pozos exploratorios en el área petrolera A-1 Norte de la Dorsal y Anticlinal Campamento de la cuenca Neuquina.

    1991-01-01

    Post-irradiation effects (PIE) ranging from normal recovery to catastrophic failure have been observed in integrated circuits during the PIE period. Data presented show failure due to rebound after a 10 krad(Si) dose. In particular, five device types are investigated with varying PIE response. Special attention has been given to the HI1-507A analog multiplexer because its PIE response is extreme. X-ray diffraction has been uniquely employed to measure physical stress in the HI1-507A metallization. An attempt has been made to show a relationship between stress relaxation and radiation effects. All data presented support the current MIL-STD Method 1019.4 but demonstrate the importance of performing PIE measurements, even when mission doses are as low as 10 krad(Si).

Da análise de conteúdo emergiram duas categorias: a doença do pé com alterações percebidas e ameaças presentes e; o cuidado com os pés, com o cuidado como preocupação com o futuro e não cuidado como sentimento de culpa. Os resultados mostraram que movidos pelas representações de alterações e ameaças os sujeitos buscam no cuidado uma esperança de não desenvolver a doença do pé ou controlar a situação. Quando o não-cuidado ocorre, surge o sentimento de culpa por terem conhecimentos e não se cuidarem.

    Full Text Available En la reconstrucción mamaria intentamos conseguir la mayor simetría posible con la mama contralateral, en el menor número de intervenciones, con la menor secuela posible y con la máxima seguridad. Cuando tenemos mala calidad cutánea en el tórax tenemos que utilizar técnicas que aportan un tejido bien vascularizado, de buena calidad, que conseguimos a cierta distancia en vez de usar los propios tejidos del tórax. En este artículo se revisa el colgajo musculocutáneo del dorsal ancho, la técnica de elevación, variaciones del colgajo, ventajas e inconvenientes del mismo. Se trata de una técnica de gran seguridad, versátil, con pocas secuelas en la zona donante, de tiempo quirúrgico relativamente corto y con buenos resultados estéticos.In breast reconstruction we try to achieve the greatest possible symmetry with the contralateral breast, with the smallest number of interventions, the least possible sequel and the greatest safety. When we find poor cutaneous quality in the thorax we must use techniques that provide a well vascularised tissue of good quality, which we obtain at a certain distance instead of using the thorax tissues themselves. This article reviews the latissimus dorsi musculocutaneous flap, the technique of elevation, variations of the flap, and the advantages and drawbacks involved. This is a very safe and versatile technique, with few sequels in the donor area, with a relatively short surgery time and with good aesthetic results.

    Full Text Available Introducción: El bloqueo del nervio ciático en la fosa poplítea proporciona una adecuada y prolongada analgesia postoperatoria en la cirugía del pie y tobillo. La principal ventaja del abordaje lateral es que no es preciso modificar la posición de decúbito supino del paciente para la realización de la técnica, mientras que en el abordaje posterior el paciente ha de colocarse en decúbito prono, lo cual puede resultar difícil e incluso desaconsejable en determinadas situaciones: estados avanzados de gestación, inestabilidad hemodinámica y ventilación mecánica. Material y método: Se incluyeron pacientes valorados con riesgo anestésico ASA I-II, programados para cirugía ortopédica-traumatológica del pie o tobillo. Se realizó un bloqueo del nervio ciático en la fosa poplítea mediante abordaje lateral según la técnica descrita por Vloka J.D y Hadzic A, empleándose una aguja para neuroestimulación, biselada de calibre 22G x 80 mm. Se consideró como respuesta motora adecuada cualquier movimiento del pie o dedos a intensidad inferior a 0,4 mA y superior a 0,1 mA. La observación de una respuesta motora a intensidad de estimulación de 0,1 mA se consideró como localización intraneural de la aguja. Se inyectaron 40 mL de ropivacaína 0,5%. Las principales variables que se registraron a las 8, 16 y 24 horas tras la realización del bloqueo fueron el dolor en reposo y en movimiento según la escala visual analógica (EVA de 0-10 y el grado de satisfacción. Resultados: Se incluyeron 21 pacientes ASA I-II. El dolor medio en reposo fue valorado como de intensidad 1 en las primeras 8 horas y de intensidad 3 a las 16 h y 24 h tras la realización del bloqueo.

    Pie menus are a well-known technique for interacting with 2D environments and so far a large body of research documents their usage and optimizations. Yet, comparatively little research has been done on the usability of pie menus in immersive virtual environments (IVEs). In this paper we reduce this gap by presenting an implementation and evaluation of an extended hierarchical pie menu system for IVEs that can be operated with a six-degrees-of-freedom input device. Following an iterative development process, we first developed and evaluated a basic hierarchical pie menu system. To better understand how pie menus should be operated in IVEs, we tested this system in a pilot user study with 24 participants and focus on item selection. Regarding the results of the study, the system was tweaked and elements like check boxes, sliders, and color map editors were added to provide extended functionality. An expert review with five experts was performed with the extended pie menus being integrated into an existing VR application to identify potential design issues. Overall results indicated high performance and efficient design.

    primordial, plume-related fractures acting throughout the entire growth of the islands. Basaltic volcanism forms the bulk of the islands and rift zones. However, collapses of the flanks of the rifts disrupt their established fissural feeding system, frequently favouring magma accumulation and residence at shallow emplacements, leading to differentiation of magmas, and intermediate to felsic nested eruptions. Rifts and their collapse may therefore act as an important factor in providing petrological variability to oceanic volcanoes. Conversely, the possibility exists that the presence of important felsic volcanism may indicate lateral collapses in oceanic shields and ridge-like volcanoes, even if they are concealed by post-collapse volcanism or partially mass-wasted by erosion.El Rift NE de Tenerife, conocido localmente como la Dorsal de La Esperanza, es un excelente ejem plo de un rift persistente y recurrente. Su estudio ha aportado evidencias significativas del origen y diná mica de este tipo de estructuras volcánicas. Los rifts son posiblemente las estructuras más relevantes en la geología de las islas volcánicas oceánicas: 1. Controlan, tal vez desde su inicio, la construcción de los edificios insulares; 2. Son elementos sustanciales en la configuración (forma y topografía de estas islas; 3. Dan origen a sus principales formas del relieve y el paisaje; 4. Al concentrar la actividad eruptiva, son asimismo estructuras cruciales en la distribución del riesgo volcánico; 5. Condicionan la distribución de recursos naturales básicos, como el agua subterránea. En las Canarias están muy bien representados tanto los rifts típicos de los estadios juveniles de desarrollo en escudo, como los más tardíos, correspondientes a las fases de rejuvenecimiento post-ero sivo. El Rift NE es un buen ejemplo de este último tipo de rifts. El Rift NE se ha desarrollado en tres etapas diferentes separadas por periodos más largos de quiescencia o actividad reducida. La primera

    The impact of epilepsy is manifest by effects related to seizures and side effects of therapy and comorbidities such as depression. This report describes the development of a brief patient-reported outcome (PRO) instrument, the Personal Impact of Epilepsy Scale (PIES), to measure the influence of epilepsy overall and in each of these domains. Instrument development followed standard procedures and an FDA Guidance. People with epilepsy were surveyed with open-ended questions to derive major themes of their concerns, resulting in 4 key areas: seizures, side effects, comorbidities, and overall quality of life (QOL). A preliminary set of 152 questions was based on these themes and completed by 50 patients, age 42.7 (range: 21-71) years, concurrent with comparator instruments, including the NH Seizure Severity Scale (NHSSS), the Liverpool Adverse Events Profile (LAEP), the Quality of Life in Epilepsy (QOLIE-31) scale, the Beck Depression Inventory, and the Epilepsy Foundation Depression: A Checklist. A multiple regression model indicated which PIES measures were associated with scores from the comparator instruments. Questions in each of the domains were selected for correlations and nonduplication. Test-retest consistency at a 3-day interval was completed by 38 subjects and a final set of questions constructed. The final question set comprised 25 items: 9 about characteristics of seizures, 7 about medication side effects, 8 about comorbidities, and 1 about overall quality of life. All items had 5 response choices (0-4), with higher scores reflecting more negative status. A total of 46 subjects completed the 25 questions. Cronbach's alpha was 0.87, indicating good internal consistency. Each of the three domains correlated well with the overall QOL item. The questions pertaining to seizures correlated with the NHSSS, the side effect questions with the LAEP, and the comorbidity questions with the QOLIE-31. The PIES provides a simple, brief PRO measure as a profile of

Se trata de pacientes incapaces de reaccionar de un modo intencional a la estimulación externa y que no manifiestan ninguna capacidad comunicativa. Estudios recientes han demostrado que en torno al 40% de estos pacientes han sido incorrectamente diagnosticados y se encuentran, en realidad, conscientes. Sin embargo, en los últimos años se ha producido una revolución en las herramientas disponibles para evaluar a estos pacientes. El presente artículo tiene como objetivo discutir el papel de las escalas de evaluación clínica estandarizadas, así como técnicas avanzadas de neuroimagen, en la reducción del alarmante error diagnóstico. Se revisarán el alcance y las limitaciones de cada aproximación para identificar signos de conciencia externos o encubiertos, y se presentará evidencia a favor de una evaluación multimodal, combinando la información clínica, estructural y funcional para garantizar el diagnóstico correcto en cada caso individual.

    2000-06-01

    Since the first criticality of HANARO reached in Feb. of 1995, the rod type U{sub 3}Si-A1 fuel imported from AECL has been used. From the under-water fuel inspection which has been conducted since 1997, a ballooning-rupture type abnormality was observed in several fuel rods. In order to find the root cause of this abnormality and to find the resolution, the post irradiation examination(PIE) was proposed as the best way. In this document, the information from the under-water inspection as well as the PIE requirements are described. Based on the information in this document, a detail test plan will be developed by the project team who shall conduct the PIE.

This paper studies the conventional spacers replacement with edible and biodegradable films made with whey protein isolate (WPI and potassium sorbate as a preservative. Besides facilitating the separation of pie caps, with this application is intended to increase their shelf life. The films made by the compression molding method were used as spacers in pie caps without preservative in their formula (A and with preservative (B and they were compared with conventional polyethylene spacers (C. During four months, monthly sensory, microbiological and physicochemical (humidity evaluations were done on the pie caps, together with humidity and solubility evaluations of the films. None of the samples showed microbiological or sensory deterioration. The sensory attributes showed no or slight difference in study time. Between samples the differences were minor: the best scores were for sample A in color, sample C in flavor, and samples B and C in texture and overall liking. The edible films have an interesting potential for this application, although studies in disguise the flavor of serum should be done.

    This paper describes the results of the post-irradiation examination (PIE) on the MOX fuel rods irradiated in the Japanese commercial PWR, MIHAMA Unit 1. The objective of the PIE is not only to confirm the fuel integrity but also to build up the irradiation data base for MOX fuel design. After three cycles irradiation up to the assembly burnup of 23 GWd/t, they were examined at the site and further PIE was carried out on eight MOX fuel rods at a hot laboratory. The non-destructive test results of PIE proved the integrity of the MOX fuel rods up to the burnup of about 25GWd/t, and revealed the similar irradiation behaviour of dimensional change with the standards UO{sub 2} fuel rods. Results of the following destructive tests also revealed the similar irradiation behaviour of FGR, fuel pellet dimensional change and cladding oxidation with the standard UO{sub 2} fuel, and confirmed no abnormality in microstructure changes of fuel pellets.

  14. The Cassini Solstice Mission: Streamlining Operations by Sequencing with PIEs

    2014-01-01

    The Cassini Solstice Mission (CSM) is the second extended mission phase of the highly successful Cassini/Huygens mission to Saturn. Conducted at a much-reduced funding level, operations for the CSM have been streamlined and simplified significantly. Integration of the science timeline, which involves allocating observation time in a balanced manner to each of the five different science disciplines (with representatives from the twelve different science instruments), has long been a labor-intensive endeavor. Lessons learned from the prime mission (2004-2008) and first extended mission (Equinox mission, 2008-2010) were utilized to design a new process involving PIEs (Pre-Integrated Events) to ensure the highest priority observations for each discipline could be accomplished despite reduced work force and overall simplification of processes. Discipline-level PIE lists were managed by the Science Planning team and graphically mapped to aid timeline deconfliction meetings prior to assigning discrete segments of time to the various disciplines. Periapse segments are generally discipline-focused, with the exception of a handful of PIEs. In addition to all PIEs being documented in a spreadsheet, allocated out-of-discipline PIEs were entered into the Cassini Information Management System (CIMS) well in advance of timeline integration. The disciplines were then free to work the rest of the timeline internally, without the need for frequent interaction, debate, and negotiation with representatives from other disciplines. As a result, the number of integration meetings has been cut back extensively, freeing up workforce. The sequence implementation process was streamlined as well, combining two previous processes (and teams) into one. The new Sequence Implementation Process (SIP) schedules 22 weeks to build each 10-week-long sequence, and only 3 sequence processes overlap. This differs significantly from prime mission during which 5-week-long sequences were built in 24 weeks

    Full Text Available Los metasedimentos del Grupo Caucete aflorantes en la sierra de Pie de Palo constituyen una pieza importante para entender la evolución del margen gondwánico durante el Proterozoico tardío a Paleozoico temprano. Esta secuencia metamórfica está en contacto tectónico, a través del Corrimiento Las Pirquitas, con el Complejo Pie de Palo (Mesoproterozoico. El Grupo Caucete está integrado por dos unidades mayores, una siliciclástica y otra carbonática, y basado en estudios de campo entre las quebradas Las Pirquitas y La Petaca y posterior laboratorio, ha sido dividido en cuatro formaciones. La parte siliciclástica incluye a la Cuarcita El Quemado, la que está intercalada con la Formación La Paz, unidad de carácter volcaniclástico. Los carbonatos están representados por la Formación El Desecho (areniscas y limolitas carbonáticas con mármoles dolomíticos y la Caliza Angacos. Los primeros resultados geoquímicos fueron utilizados para comparar la Cuarcita El Quemado y la Formación La Paz con las metagrauvacas del Complejo Pie de Palo. Su composición mineralógica ha determinado el comportamiento geoquímico de los elementos mayoritarios, mientras que las tierras raras y elementos traza, al estar concentrados principalmente en los minerales pesados, muestran que los procesos sedimentarios han jugado un rol importante en su distribución. Los sedimentos siliciclásticos se habrían originado por la destrucción de rocas corticales procedentes de áreas orogénicas, con un importante componente félsico asociado con rocas ígneas originadas en arcos magmáticos más o menos evolucionados. Los mismos se habrían depositado en una plataforma continental durante el Proterozoico superior (670 Ma, U/Pb en circones detríticos.Metasedimentary rocks of the Caucete Group outcropping at the western slope of Sierra de Pie de Palo are an important key to understand the geological evolution of the western margin of Gondwana during late Proterozoic

  20. Dissociation of the dorsal-cactus complex and phosphorylation of the dorsal protein correlate with the nuclear localization of dorsal

    OpenAIRE

    1993-01-01

    The formation of dorsal-ventral polarity in Drosophila requires the asymmetric nuclear localization of the dorsal protein along the D/V axis. This process is regulated by the action of the dorsal group genes and cactus. We show that dorsal and cactus are both phosphoproteins that form a stable cytoplasmic complex, and that the cactus protein is stabilized by its interaction with dorsal. The dorsal-cactus complex dissociates when dorsal is targeted to the nucleus. While the phosphorylation of ...

    Ski-jump energy dissipators are widely used in hydraulic engineering because of their well-known effectiveness. Nevertheless, some uncertainty exits associated with the dimensions of the scour hole appearing downstream of the structure. This paper presents a new method for solving this problem. This method includes spillway stability checking as part of the design process and also stability checking of any other construction near the energy dissipation zone. [Spanish] Los disipadores de energia tipo trampolin tienen amplia utilizacion en la practica de la ingenieria hidraulica por su probada eficacia; sin embargo, su diseno esta sujeto a cierto grado de incertidumbre en cuanto a la prediccion de las dimensiones del cono de socavacion que habra de producirse aguas abajo de la estructura. En el presente trabajo se muestra un metodo novedoso, mediante el cual el autor soluciona el aspecto antes referido, toda vez que se incluye como parte del proceso de diseno la comprobacion de la estabilidad del propio aliviadero o de cualquier otra obra cercana a la zona de disipacion de energia.

    For the evaluation of safety and integrity of light water reactors (LWRs), various post irradiation examinations (PIEs) of reactor pressure vessel (RPV) steels and fuel claddings have been carried out in the Research Hot Laboratory (RHL). In recent years, the instrumented Charpy impact testing machine was remodeled aiming at the improvement of accuracy and reliability. By this remodeling, absorbed energy and other useful information on impact properties can be delivered from the force-displacement curve for the evaluation of neutron irradiation embrittlement behavior of LWR-RPV steels at one-time striking. In addition, two advanced PIE technologies are now under development. One is the remote machining of mechanical test pieces from actual irradiated pressure vessel steels. The other is development of low-cycle and high-cycle fatigue test technology in order to clarify the post-irradiation fatigue characteristics of structural and fuel cladding materials. (author)

    Developmental anomalies of the pancreas have been reported but dorsal pancreatic agenesis is an extremely rare entity. We report an asymptomatic 62-year-old woman with complete agenesis of the dorsal pancreas.Abdominal computed tomography (CT) revealed a normal pancreatic head, but pancreatic body and tail were not visualized. Magnetic resonance imaging (MRI)findings were similar to CT. At magnetic resonance cholangiopancreatography (MRCP), the major pancreatic duct was short and the dorsal pancreatic duct was not visualized. The final diagnosis was dorsal pancreatic agenesis.

    2016-05-01

    Outbreaks of foodborne illness caused by Bacillus cereus and Listeria monocytogenes in England associated with meat pie consumption were detected in 2012. To obtain baseline data for pies unrelated to outbreaks, 862 samples of ready-to-eat meat pies were collected at retail or from catering facilities in England in 2013 and examined to enumerate food-poisoning bacteria and indicator organisms using Organization for Standardization (ISO) methods for Listeria spp. including L. monocytogenes (ISO 11290), Clostridium perfringens (ISO 21528), coagulase-positive staphylococci including Staphylococcus aureus (ISO 6888), Bacillus spp. including B. cereus (ISO 1737), Escherichia coli (ISO 16649), Enterobacteriaceae (ISO 21528), and aerobic colony counts (ACCs; ISO 4833). Microbiological quality was satisfactory in 94% of samples, borderline in 5%, and unsatisfactory in 1%. The proportion of pies from markets that were borderline or unsatisfactory significantly increased, and the proportion of borderline or unsatisfactory pies from supermarkets significantly decreased. Among the refrigerated (0 to 15°C) pies, microbiological quality significantly decreased in pies stored at >8°C and further significantly decreased at in pies stored at ambient temperature (>15 to 25°C). Samples collected at 25 to 40°C had the highest proportion of borderline or unsatisfactory results, but results improved in pies stored at >40°C. The most common cause for borderline or unsatisfactory results was elevated ACCs (5% of all samples). Within the individual microbiological parameters, borderline or unsatisfactory results resulted from elevated Enterobacteriaceae or Bacillus levels (10 samples for each), C. perfringens levels (2 samples), and S. aureus or E. coli levels (1 sample each). L. monocytogenes was recovered from one pie at <10 CFU/g. A literature review revealed a range of microbiological hazards responsible for food poisoning and meat pie consumption, and surveillance data from 1992

  4. Magnetic Resonance Imaging: A Tool for Pork Pie Development.

    Science.gov (United States)

    Gaunt, Adam P; Morris, Robert H; Newton, Michael I

    2013-08-28

    The traditional British pork pie consists of roughly chopped pork cooked in a hot water pastry crust. Due to shrinkage of the meat during cooking, the gap formed around the meat is usually sealed using a gelatin based jelly to exclude air and thus help to preserve the pie. The properties of the jelly are such that it will ingress into the pastry crust causing undesirable softening. The jelly is traditionally produced by simmering pig trotters with seasoning for several hours. In this work we demonstrate the potential of magnetic resonance imaging (MRI) as a tool for investigating the conditions required for producing jellies with different properties and present two examples of this use. Firstly we demonstrate that MRI can determine the ability of water to diffuse through the jelly which is critical in minimizing the amount of moisture moving from the jelly to the crust. Secondly, the impact of jelly temperature on the penetration length into the crust is investigated. These examples highlight the power of MRI as a tool for food assessment.

  5. Introducing a Framework for Physics Innovation and Entrepreneurship (PIE) Education

    Science.gov (United States)

    Roughani, Bahram

    A desired outcome for Physics Innovation and Entrepreneurship (PIE) education is preparing physics majors with an innovative and entrepreneurial mindset who are capable of opportunity recognition and adept in leveraging physics knowledge to address specific needs. Physics as a discipline is well-recognized to prepare students who become problem solvers and critical thinkers, gifted in dealing with abstract ideas and ambiguities in the context of complex and real-world problems. These characteristics when enhanced through appropriate combinations of curricular, co-curricular, and extra-curricular programs can prepare physics majors for careers and future challenges that may involve translating physics knowledge into useful products and services either as part of a technical team within an organization or through startups. A viable PIE education model prepares graduates for various career paths in addition to the traditional options such as pursuing graduate studies or becoming a science teacher. Having a well-defined ``third option'' for physics will benefit the robustness of the physics discipline through recruitment and retention of prospective students who in principle are interested in physics as a subject, but in practice they may overlook physics as their preferred major primarily because they are uncertain about a viable career path based on an undergraduate physics education. The ''Pathways to Innovation'' at Loyola is established based on the program developed by VentureWell and Epicenter (NSF Supported).

  12. Structural Conservation and Functional Diversity of the Poxvirus Immune Evasion (PIE) Domain Superfamily.

    Science.gov (United States)

    Nelson, Christopher A; Epperson, Megan L; Singh, Sukrit; Elliott, Jabari I; Fremont, Daved H

    2015-08-28

    Poxviruses encode a broad array of proteins that serve to undermine host immune defenses. Structural analysis of four of these seemingly unrelated proteins revealed the recurrent use of a conserved beta-sandwich fold that has not been observed in any eukaryotic or prokaryotic protein. Herein we propose to call this unique structural scaffolding the PIE (Poxvirus Immune Evasion) domain. PIE domain containing proteins are abundant in chordopoxvirinae, with our analysis identifying 20 likely PIE subfamilies among 33 representative genomes spanning 7 genera. For example, cowpox strain Brighton Red appears to encode 10 different PIEs: vCCI, A41, C8, M2, T4 (CPVX203), and the SECRET proteins CrmB, CrmD, SCP-1, SCP-2, and SCP-3. Characterized PIE proteins all appear to be nonessential for virus replication, and all contain signal peptides for targeting to the secretory pathway. The PIE subfamilies differ primarily in the number, size, and location of structural embellishments to the beta-sandwich core that confer unique functional specificities. Reported ligands include chemokines, GM-CSF, IL-2, MHC class I, and glycosaminoglycans. We expect that the list of ligands and receptors engaged by the PIE domain will grow as we come to better understand how this versatile structural architecture can be tailored to manipulate host responses to infection.

  14. The causal pie model: an epidemiological method applied to evolutionary biology and ecology.

    A general concept for thinking about causality facilitates swift comprehension of results, and the vocabulary that belongs to the concept is instrumental in cross-disciplinary communication. The causal pie model has fulfilled this role in epidemiology and could be of similar value in evolutionary biology and ecology. In the causal pie model, outcomes result from sufficient causes. Each sufficient cause is made up of a "causal pie" of "component causes". Several different causal pies may exist for the same outcome. If and only if all component causes of a sufficient cause are present, that is, a causal pie is complete, does the outcome occur. The effect of a component cause hence depends on the presence of the other component causes that constitute some causal pie. Because all component causes are equally and fully causative for the outcome, the sum of causes for some outcome exceeds 100%. The causal pie model provides a way of thinking that maps into a number of recurrent themes in evolutionary biology and ecology: It charts when component causes have an effect and are subject to natural selection, and how component causes affect selection on other component causes; which partitions of outcomes with respect to causes are feasible and useful; and how to view the composition of a(n apparently homogeneous) population. The diversity of specific results that is directly understood from the causal pie model is a test for both the validity and the applicability of the model. The causal pie model provides a common language in which results across disciplines can be communicated and serves as a template along which future causal analyses can be made.

    Full Text Available El pie diabético es una complicación crónica de la diabetes mellitus y constituye una problemática sanitaria al conllevar un enorme gasto económico a los servicios sanitarios y provocar a las personas que lo padecen y a su entorno familiar enormes repercusiones emocionales. La educación sanitaria en el cuidado de los pies de los diabéticos, así como la cuantificación del riesgo son aspectos que el enfermero debe incorporar en los planes de cuidados de los pacientes diabéticos. La detección de los posibles factores de riesgo es un paso previo imprescindible para estos cometidos. Este estudio tiene como finalidad analizar la presencia de determinados factores de riesgo en pie diabético en la población diabética del Centro de Salud de Triana, con el objetivo de poder realizar, así, una estratificación del riesgo. Para ello, se optó por la realización de un estudio observacional descriptivo. La muestra analizada estaba constituida por 96 sujetos diabéticos pertenecientes a dicho centro de salud. Para la recogida de datos se utilizó un sistema de tres niveles consistente en entrevista, exploración física y consulta de registros disponibles (a través de las historias clínicas de los sujetos. Los datos se registraron en un formulario de recogida de datos para pie diabético. Se determinó la existencia de factores de riesgo, analizando las relaciones entre éstos y permitiendo la estratificación del riesgo en la población estudiada.The diabetic foot is a chronic complication of diabetes mellitus and constitutes a sanitary problem which causes not only enormous expenses for the sanitary system but also provokes emotional repercussions for the person who suffers the illness and for the family.

  19. Heat and Ice in Sermilik Fjord: Novel Observational Techniques Using PIES

    Science.gov (United States)

    Andres, M.; Straneo, F.; Sutherland, D.

    2014-12-01

    A 1-year pilot experiment using pressure-sensor-equipped inverted echo sounders (PIES) was conducted in Sermilik Fjord in eastern Greenland to test non-traditional methods for measuring the time-varying
heat content in high-latitude seas, shelves, and fjords and for detecting the presence of ice. PIES, which are installed on the seafloor below the reach of destructive iceberg keels, present
a promising and inexpensive way to improve understanding of fjord dynamics and shelf-fjord interactions and will increase long-term monitoring capabilities in high latitudes where
remoteness and harsh conditions hamper traditional in situ observation techniques. The use
of PIES to characterize variability at high latitudes is a novel application of an existing
technology, but rests on the same principle as the traditional blue-water uses for PIES: due
to the dependence of sound speed on temperature, the surface-to-bottom round-trip acoustic-travel-time associated with reflections between the PIES and the air-sea interface is an excellent proxy
for heat content in the intervening water column. Furthermore, since reflections from seawater-ice interfaces are also detected when ice
is present, PIES provide a means to characterize the ice component in high-latitude systems. The PIES deployed in Sermilik Fjord (August 2011 - September 2012) resolved changes in heat content at scales ranging from hourly to seasonal. Furthermore, during winter, the PIES logged about 300 iceberg detections and recorded a 2-week period of land-fast ice cover in March. The deepest icebergs in the fjord were found to have keel depths reaching to ~350 m and iceberg speeds averaged about 0.2 m/s but were as high as 0.5 m/s.

    Full Text Available Antecedentes: Peroneo meñique quinti es uno de los muchos músculos peroneos accesorios que por lo general se origina como un pequeño deslizamiento del tendón del peroneo lateral corto, alrededor del maléolo lateral, y se une a la aponeurosis dorsal del quinto dígito. No se conoce con precisión la prevalencia de la misma. Hay mucha confusión en la literatura, ya que existen múltiples clasificaciones superpuestas y una gran variedad de terminología descriptiva acerca de los músculos peroneos accesorios. Peroneo meñique quinti fue observado por algunos investigadores en la literatura, pero Macalister (1872 y Testut (1921 describen este músculo con sus variaciones en  detalle. Material y métodos: Se estudiaron 100 miembros inferiores de cadáveres adultos de sexo desconocido. El compartimento lateral de cada pie se disecó cuidadosamente para determinar la incidencia del peroneo lateral del meñique quinti. Se observó su origen y la inserción, y se tomó el diámetro. Resultados: Se observó este músculo en el 51% de los casos, con predominio del lado izquierdo. Estaba presente bilateralmente sólo en un 5% las extremidades inferiores. Su diámetro varía de 0,7mm a 3mm. Informamos mayor incidencia de este músculo con la variación en sus anexos distales. El conocimiento de esta variante muscular es importante no solo para anatomistas sino también para los cirujanos en el diagnostico de dolores de la región lateral del tobillo y del pie.

  3. $\\pi_{e3}$ form factor $f_{-}$ near mass shell

    CERN Document Server

    Krivoruchenko, M I

    2014-01-01

    Generalized Ward-Takahashi identity (gWTI) in the pion sector for broken isotopic symmetry is derived and used for the model-independent calculation of the longitudinal form factor $f_{-}$ of the $\\pi_{e3}$ vector vertex. The on-shell $f_{-}$ is found to be proportional to the mass difference of pions and the difference between vector isospin $ T = 1 $ and scalar isospin $ T = 2 $ pion radii. A numerical estimate of the form factor gives a value two times higher than the earlier estimate in the quark model. Off-shell form factors are known to be ambiguous because of the gauge dependence and the freedom in parameterization of the fields. The near-mass-shell $f_{-}$ appears to be an exception, allowing the experimental verification of the gWTI consequences. We calculate the near-mass-shell $f_{-}$ using the gWTI and dispersion techniques. The results are discussed in the context of the conservation of vector current (CVC) condition.

    Full Text Available Se realizaron varias pruebas piloto con sísmica de reflexión de baja profundidad en depósitos de abanicos aluviales distales en la provincia de Salta, Argentina. Las pruebas incluyen dos áreas con características de subsuelo contrastantes. En el sector nororiental de la provincia, los depósitos del extenso abanico aluvial del Bermejo son arenosos y macizos, casi sin intercalaciones arcillosas; la napa se encontraba a más de 40 m de profundidad al tiempo del estudio. La otra zona de prueba se ubica al sur de la ciudad de Salta, donde coalescen abanicos aluviales pequeños que rellenan el valle de Lerma con depósitos de arena y grava, los cuales en los tramos distales se interdigitan con potentes capas arcillosas; la napa en esta área se hallaba a una profundidad mayor de 20 m al momento del estudio. La operación sísmica empleó un sismógrafo Geometrics R24 con 24 canales activos que se aumentaron a 48 mediante un "roll-over switch", alcanzando un máximo de cobertura de 1200%. Se probaron dos fuentes de sonido: una masa de 5 kg y una escopeta calibre 12. Principalmente por razones operativas se eligió como fuente la masa. Las pruebas en el abanico del Bermejo dieron registros de baja calidad, probablemente debido a la rápida pérdida de energía en las areas poco consolidadas y secas. Localmente, sin embargo, pudieron distinguirse tres unidades sísmicas y el techo del Terciario posiblemente fue detectado. Las pruebas en eje del valle de Lerma dieron registros sísmicos de excelente calidad. Se distinguieron cuatro unidades sísmicas. Un reflector débil a aproximadamente 220 mseg coincide con un cambio de las velocidades a unos 2500 m/seg y puede corresponder con el techo del sustrato terciario. Una potente capa de arcilla a una profundidad de 25 a 50 m puede claramente mapearse como un acuitardo. Los resultados de este estudio piloto demuestran que la sísmica de reflexión de poca profundidad puede ser aplicada con provecho en el

  7. An Assessment of ORNL PIE Capabilities for the AGR Program Capsule Post Irradiation Examination

    2006-09-01

    ORNL has facilities and experienced staff that can execute +the Advanced Gas Reactor (AGR) Post Irradiation Examination (PIE) task. While the specific PIE breakdown needs to be more formally defined, the basic outline is clear and the existing capabilities can be assessed within the needs of the tasks defined in the program plan. A one-to-one correspondence between the program plan tasks and the current ORNL PIE status was conducted and while some shortcomings were identified, the general capability is available. Specific upgrade needs were identified and reviewed. A path forward was formulated. Building 3525 is available for this work and this building is currently receiving renewed attention from management so that it will be in good working order prior to the expected PIE start date. This building is equipped with the tools necessary for PIEs of this nature, but the long hiatus in coated particle fuel work has left it with aging analysis tools. This report identified several of these tools and rough estimates of what would be required to update and replace them. In addition, other ORNL buildings are available to support Building 3525 in specialized tasks along with the normal laboratory infrastructure. Before the AGR management embarks on any equipment development effort, the PIE tasks should be updated against current program (modeling and data) needs and better defined so that the items to be measured, their measurement uncertainties, and thru-put needs can be reviewed. A Data Task Matrix (DTM) should be prepared so that the program data needs can be compared against the identified PIE tasks and what is practical in the hot cell environment to make sure nothing is overlooked. Finally, thought should be given to the development of standardized equipment designs between sites to avoid redundant design efforts and different measurement techniques. This is a potentially cost saving effort that can also avoid data inconsistencies.

    Protein-protein interaction (PPI) extraction has been an important research topic in bio-text mining area, since the PPI information is critical for understanding biological processes. However, there are very few open systems available on the Web and most of the systems focus on keyword searching based on predefined PPIs. PIE (Protein Interaction information Extraction system) is a configurable Web service to extract PPIs from literature, including user-provided papers as well as PubMed articles. After providing abstracts or papers, the prediction results are displayed in an easily readable form with essential, yet compact features. The PIE interface supports more features such as PDF file extraction, PubMed search tool and network communication, which are useful for biologists and bio-system developers. The PIE system utilizes natural language processing techniques and machine learning methodologies to predict PPI sentences, which results in high precision performance for Web users. PIE is freely available at http://bi.snu.ac.kr/pie/.

    Dorsal variant proximal carotid blister aneurysms are treacherous lesions to manage. It is important to recognize this variant on preoperative angiographic imaging, in anticipation of surgical strategies for their treatment. Strategies include trapping the involved segment and revascularization if necessary. Other options include repair of the aneurysm rupture site directly. Given that these are not true berry aneurysms, repair of the rupture site involves wrapping or clip-grafting techniques. The case presented here was a young woman with a subarachnoid hemorrhage from a ruptured dorsal variant blister aneurysm. The technique used is demonstrated in the video and is a modified clip-wrap technique using woven polyester graft material. The patient was given aspirin preoperatively as preparation for the clip-wrap technique. It is the authors' current protocol to attempt a direct repair with clip-wrapping and leaving artery sacrifice with or without bypass as a salvage therapy if direct repair is not possible. Assessment of vessel patency after repair is performed by intraoperative Doppler and indocyanine green angiography. Intraoperative somatosensory and motor evoked potential monitoring is performed in all cases. The video can be found here: http://youtu.be/crUreWGQdGo.

    During the last 100 years in medical literature, there are only 54 reports, including the report of Pasaoglu et al ( World J Gastroenterol 2008; 14: 2915-2916), with clinical descriptions of agenesis of the dorsal panc reas in humans . Agenes i s of the dor sal pancreas, a rare congenital pancreatic malformation,is associated with some other medical conditions such as hyperglycemia, abdominal pain, pancreatitis and a few other diseases. In approximately 50% of reported patients with this congenital malformation,hyperglycemia was demonstrated. Evaluation of hyperglycemia and diabetes mellitus in all patients with agenesis of the dorsal pancreas including description of fasting blood glucose, oral glucose tolerance test, glycated hemoglobin and medical treatment would be a future goal. Since autosomal dominant transmission has been suggested in single families,more family studies including imaging technologies with demonstration of the pancreatic duct system are needed for evaluation of this disease. With this letter to the editor, we aim to increase available information for the better understanding of this rare disease.

    Background Based on our clinical experience, the number of dorsal penile nerves in patients with primary premature ejaculation (PPE) is not consistent with the average number (2 branches). In this study, we evaluated the number and distribution of dorsal penile nerves among healthy Chinese adults and patients with PPE.Methods The dorsal nerve of the penis, the deep dorsal vein of the penis, and the dorsal artery of the penis between the deep fascia of the penis and the albuginea penis were carefully educed, observed, and counted in 38 adult autopsy specimens. The number and distribution of the dorsal penile nerve in 128 surgical patients with PPE were determined. Results The numbers of dorsal penile nerves of the 38 cases were as follows:7 branches in 1 case; 6 branches in 1 case; 5 branches in 6 cases; 4 branches in 9 cases; 3 branches in 14 cases; and 2 branches in 7 cases. Most of the dorsal nerves were parallel to each other and in the dorsum of the penis. In only 8 cases, the branches were connected by some communicating branches. In 4 cases, 1 or 2 thin dorsal nerves continued their pathway over the ventral aspect of the penis. The average number of branches of the dorsal penile nerve in patients with PPE was 7.16. Conclusions Based on the study of 38 cases, the average number of dorsal penile nerves was 3.55 branches and that of patients with PPE was greater. These preliminary results suggest that the excessive dorsal penile nerves may have an impact on PPE via increased sensitivity and provide topographic data for the possible treatment of PPE.

    2009-02-01

    The theory of illumination subspaces is well developed and has been tested extensively on the Yale Face Database B (YDB) and CMU-PIE (PIE) data sets. This paper shows that if face recognition under varying illumination is cast as a problem of matching sets of images to sets of images, then the minimal principal angle between subspaces is sufficient to perfectly separate matching pairs of image sets from nonmatching pairs of image sets sampled from YDB and PIE. This is true even for subspaces estimated from as few as six images and when one of the subspaces is estimated from as few as three images if the second subspace is estimated from a larger set (10 or more). This suggests that variation under illumination may be thought of as useful discriminating information rather than unwanted noise.

  17. Progress on accelerated calculation of 3D MHD equilibrium with the PIES code

    Raburn, Daniel; Reiman, Allan; Monticello, Donald

    2016-10-01

    Continuing progress has been made in accelerating the 3D MHD equilibrium code, PIES, using an external numerical wrapper. The PIES code (Princeton Iterative Equilibrium Solver) is capable of calculating 3D MHD equilibria with islands. The numerical wrapper has been demonstrated to greatly improve the rate of convergence in numerous cases corresponding to equilibria in the TFTR device where magnetic islands are present; the numerical wrapper makes use of a Jacobian-free Newton-Krylov solver along with adaptive preconditioning and a sophisticated subspace-restricted Levenberg backtracking algorithm. The wrapper has recently been improved by automation which combines the preexisting backtracking algorithm with insights gained from the stability of the Picard algorithm traditionally used with PIES. Improved progress logging and stopping criteria have also been incorporated in to the numerical wrapper.

    To generate cellular diversity in developing organisms while simultaneously maintaining the developmental potential of the germline, germ cells must be able to preferentially endow germline daughter cells with a cytoplasmic portion containing specialized cell fate determinants not inherited by somatic cells. In Caenorhabditis elegans, germline inheritance of the protein PIE-1 is accomplished by first asymmetrically localizing the protein to the germplasm before cleavage and subsequently degrading residual levels of the protein in the somatic cytoplasm after cleavage. Despite its critical involvement in cell fate determination, the enrichment of germline determinants remains poorly understood. Here, combining live-cell fluorescence methods and kinetic modeling, we demonstrate that the enrichment process does not involve protein immobilization, intracellular compartmentalization, or localized protein degradation. Instead, our results support a heterogeneous reaction/diffusion model for PIE-1 enrichment in which the diffusion coefficient of PIE-1 is reversibly reduced in the posterior, resulting in a stable protein gradient across the zygote at steady state.

  19. On the Fair Division of Multiple Stochastic Pies to Multiple Agents within the Nash Bargaining Solution

    The fair division of a surplus is one of the most widely examined problems. This paper focuses on bargaining problems with fixed disagreement payoffs where risk-neutral agents have reached an agreement that is the Nash-bargaining solution (NBS). We consider a stochastic environment, in which the overall return consists of multiple pies with uncertain sizes and we examine how these pies can be allocated with fairness among agents. Specifically, fairness is based on the Aristotle’s maxim: “equals should be treated equally and unequals unequally, in proportion to the relevant inequality”. In this context, fairness is achieved when all the individual stochastic surplus shares which are allocated to agents are distributed in proportion to the NBS. We introduce a novel algorithm, which can be used to compute the ratio of each pie that should be allocated to each agent, in order to ensure fairness within a symmetric or asymmetric NBS.

    Negotiators often fail to reach integrative ("win-win") agreements because they think that their own and other’s preferences are diametrically opposed—the so-called fixed-pie perception. We examined how verbal (Experiment 1) and nonverbal (Experiment 2) emotional expressions may reduce fixed-pie

    The paper presents the application of the Galerkin method to solving the parametric integral equation system (PIES) on the example of Laplace's equation. The main aim of the paper is the analysis of the effectiveness of two methods for PIES solving: the collocation method and the Galerkin method. Researches were performed on two examples with analytical solutions. Tests concern mainly the accuracy of obtained numerical solutions and their stability. For both analyzed methods calculations were made with the various number of expressions in the approximation series, whilst in the collocation method two variants of the arrangement of collocation points were considered. We also compared the complexity of both methods using the execution time.

    Full Text Available Introducción Las fracturas Salter-Harris VI (SHVI son lesiones que se caracterizan por presentar ablación del anillo pericondral. Son infrecuentes en niños pero potencialmente devastadoras. El objetivo de este estudio fue evaluar el mecanismo de producción, el tratamiento y los resultados funcionales de estas lesiones localizadas en el pie y el tobillo. Material y métodos Se analizaron retrospectivamente todos los pacientes con lesiones SHVI de tobillo y pie tratadas entre Enero de 2010 y Enero de 2013. Se documentaron datos demográficos, clasificación, mecanismo de lesión, tipo de lesiones asociadas y número de cirugías que requirieron. Los pacientes fueron evaluados funcionalmente con el score de AOFAS y radiográficamente para determinar la viabilidad de la fisis, acortamiento del miembro o deformidad angular. Resultados Se analizaron 5 fracturas en 4 pacientes (3 masculinos y 1 femenino. La edad promedio al momento de la lesión fue de 7.5 años (rango, 6  a 10 años. El seguimiento promedio fue de 26.2 meses (rango, 12 - 37 meses. De acuerdo a la subclasificación de Peterson 3 pertenecían al grupo A, 1 al B y 1 al C. 3 lesiones se produjeron como consecuencia de accidentes de moto y 2 por auto versus peatón. Todos los casos se acompañaron de pérdida de sustancia, el 75% presentaba lesiones en más de un hueso y el 50% lesiones tendinosas asociadas.

    Full Text Available Se identificaron los conocimientos y conductas de los pacientes con diabetes mellitus sobre el pie diabético. Se realizó un estudio cualitativo en 2 consultorios del Policlínico "Hermanos Ruíz Aboy", del municipio San Miguel del Padrón. Se ejecutaron 4 grupos focales, con un total de 28 participantes de ambos sexos, entre 50 y 80 años de edad. La mayoría de los pacientes mostró falta de conocimientos sobre la definición de pie diabético y sus factores de riesgo. Los pacientes realizan un autocuidado insuficiente de sus pies y asumen conductas de riesgo por la falta de educación. Consideramos importante reforzar el componente educativo en la atención integral de los pacientes con diabetes mellitus para elevar su nivel de conocimientos, crear hábitos saludables y evitar la aparición del pie diabético. La técnica del grupo focal constituyó un instrumento rápido y efectivo para la obtención de información.The knowledge and behavior of the patients with diabetes mellitus in connection with the diabetic foot were identified. A qualitative study was conducted in 2 family physician's offices of "Hermanos Ruíz Aboy" Polyclinic of San Miguel del Padrón municipality. 4 focal groups were selected with a total of 28 participants aged 50-80 of both sexes. Most of the patients lacked knowledge to define the diabetic foot and its risk factors. The patients' self-care of their feet is insufficient and they assume risk conducts due to their deficient education. It is important to reinforce the educative component in the comprehensive attention of the patients with diabetes mellitus to raise their knowledge level, to create healthy habits and to prevent the appearance of diabetic foot. The focal group technique is a rapid and effective tool to obtain information.

    Established for lateral release in TKA, the pie-crusting technique has not been studied for the medial collateral ligament (MCL). In cadaveric knees the MCL was release with a pie-crusting technique in one and traditional technique in the contralateral knee. Along with a control group, each MCL was subjected to mechanical testing. The stiffness, force and stress required to cause ligament elongation were less in the pie-crusting group (p pie-crusting group demonstrated a characteristic "stair-step" failure mode at the joint line, whereas the traditional group failed elastically at the tibial insertion. MCL pie-crusting is likely technique dependent since failure occurs within the ligament itself and further study is warranted.

    Liu, H X; Wen, H; Hu, Y Z; Yu, H C; Pan, X Y

    2014-05-01

    To release extension contracture of the knee, the authors used a minimally invasive technique: percutaneous quadriceps tendon pie-crusting release. Percutaneous pie-crusting release was performed using an 18-gauge needle to puncture the stiff fibrous band of the distal and lateral quadriceps tendon under maximum knee flexion. Quadriceps contracture was gradually released by multiple needle punctures. A knee brace was prescribed for one week and knee flexion exercises were performed on the first postoperative day. This technique was performed in seven post-traumatic stiff knees and five stiff total knee arthroplasties. Mean maximum flexion increased from 37° preoperatively to 50° after arthrolysis and 107(o) after pie-crusting. At a mean follow-up of eight months, mean maximum flexion was 103°. There were no major complications. The technique of quadriceps tendon pie-crusting release is a simple, minimally invasive and effective treatment for knee extension contracture.

    The Department of Hot Laboratories (DHL) operates three hot cell facilities, which are the Reactor Fuel Examination Facility (RFEF), the Research Hot Laboratory (RHL) and the Waste Safety Testing Facility (WASTEF). The RFEF is especially examining the reliability of actual power reactor fuel assemblies for PWR and BWR. The RHL is established to perform post irradiation examinations (PIEs) for fuels and materials irradiated in research and test reactors. In the WASTEF, Synroc and new ceramic waste forms were prepared and investigated for the safety disposal of high level radioactive waste. At present, one of concentrated works is the PIE of high burnup fuels, for which the RFEF improved and developed several apparatuses such as thermal properties measurement and microscopic analysis. The other is the PIE concerning with studies of component aging and structural reliability, for which the charpy impact-testing machine is instrumented and a low-cycle and high-cycle fatigue test apparatus is now under developing in the RHL. This paper describes these development and application of PIE apparatuses in DHL. (author)

    Lakhujani, Vijay; Badapanda, Chandan

    2017-06-01

    QIIME (Quantitative Insights Into Microbial Ecology) is one of the most popular open-source bioinformatics suite for performing metagenome, 16S rRNA amplicon and Internal Transcribed Spacer (ITS) data analysis. Although, it is very comprehensive and powerful tool, it lacks a method to provide publication ready taxonomic pie charts. The script plot_taxa_summary.py bundled with QIIME generate a html file and a folder containing taxonomic pie chart and legend as separate images. The images have randomly generated alphanumeric names. Therefore, it is difficult to associate the pie chart with the legend and the corresponding sample identifier. Even if the option to have the legend within the html file is selected while executing plot_taxa_summary.py, it is very tedious to crop a complete image (having both the pie chart and the legend) due to unequal image sizes. It requires a lot of time to manually prepare the pie charts for multiple samples for publication purpose. Moreover, there are chances of error while identifying the pie chart and legend pair due to random alphanumeric names of the images. To bypass all these bottlenecks and make this process efficient, we have developed a python based program, prepare_taxa_charts.py, to automate the renaming, cropping and merging of taxonomic pie chart and corresponding legend image into a single, good quality publication ready image. This program not only augments the functionality of plot_taxa_summary.py but is also very fast in terms of CPU time and user friendly.

    The International Workshop on Characterization and PIE Needs to Support Science-Based Development of Innovative Fuels was held June 16-17, 2011, in Paris, France. The Organization for Economic Co-operation and Development (OECD), Nuclear Energy Agency (NEA) Working Party on the Fuel Cycle (WPFC) sponsored the workshop to identify gaps in global capabilities that need to be filled to meet projected needs in the 21st century. First and foremost, the workshop brought nine countries and associated international organizations, together in support of common needs for nuclear fuels and materials testing, characterization, PIE, and modeling capabilities. Finland, France, Germany, Republic of Korea, Russian Federation, Sweden, Switzerland, United Kingdom, United States of America, IAEA, and ITU (on behalf of European Union Joint Research Centers) discussed issues and opportunities for future technical advancements and collaborations. Second, the presentations provided a base level of understanding of current international capabilities. Three main categories were covered: (1) status of facilities and near term plans, (2) PIE needs from fuels engineering and material science perspectives, and (3) novel PIE techniques being developed to meet the needs. The International presentations provided valuable data consistent with the outcome of the National Workshop held in March 2011. Finally, the panel discussion on 21st century PIE capabilities, created a unified approach for future collaborations. In conclusion, (1) existing capabilities are not sufficient to meet the needs of a science-based approach, (2) safety issues and fuels behavior during abnormal conditions will receive more focus post-Fukushima; therefore we need to adopt our techniques to those issues, and (3) International collaboration is needed in the areas of codes and standards development for the new techniques.

    Single-pair Förster resonance energy transfer (spFRET) experiments using single-molecule burst analysis on a confocal microscope are an ideal tool to measure inter- and intramolecular distances and dynamics on the nanoscale. Different techniques have been developed to maximize the amount of information available in spFRET burst analysis experiments. Multiparameter fluorescence detection (MFD) is used to monitor a variety of fluorescence parameters simultaneously and pulsed interleaved excitation (PIE) employs direct excitation of the acceptor to probe its presence and photoactivity. To calculate accurate FRET efficiencies from spFRET experiments with MFD or PIE, several calibration measurements are usually required. Herein, we demonstrate that by combining MFD with PIE information regarding all calibration factors as well as an accurate determination of spFRET histograms can be performed in a single measurement. In addition, the quality of overlap of the different detection volumes as well as the detection of acceptor photophysics can be investigated with MFD-PIE. Bursts containing acceptor photobleaching can be identified and excluded from further investigation while bursts that contain FRET dynamics are unaffected by this analysis. We have employed MFD-PIE to accurately analyze the effects of nucleotides and substrate on the interdomain separation in DnaK, the major bacterial heat shock protein 70 (Hsp70). The interdomain distance increases from 47 Å in the ATP-bound state to 84 Å in the ADP-bound state and slightly contracts to 77 Å when a substrate is bound. This is in contrast to what was observed for the mitochondrial member of the Hsp70s, Ssc1, supporting the notion of evolutionary specialization of Hsp70s for different cellular functions in different organisms and cell organelles.

  13. Dorsal spinal epidural cavernous hemangioma

    2010-01-01

    Full Text Available A 61-year-old female patient presented with diffuse pain in the dorsal region of the back of 3 months duration. The magnetic resonance imaging showed an extramedullary, extradural space occupative lesion on the right side of the spinal canal from D5 to D7 vertebral levels. The mass was well marginated and there was no bone involvement. Compression of the adjacent thecal sac was observed, with displacement to the left side. Radiological differential diagnosis included nerve sheath tumor and meningioma. The patient underwent D6 hemilaminectomy under general anesthesia. Intraoperatively, the tumor was purely extradural in location with mild extension into the right foramina. No attachment to the nerves or dura was found. Total excision of the extradural compressing mass was possible as there were preserved planes all around. Histopathology revealed cavernous hemangioma. As illustrated in our case, purely epidural hemangiomas, although uncommon, ought to be considered in the differential diagnosis of spinal epidural soft tissue masses. Findings that may help to differentiate this lesion from the ubiquitous disk prolapse, more common meningiomas and nerve sheath tumors are its ovoid shape, uniform T2 hyperintense signal and lack of anatomic connection with the neighboring intervertebral disk or the exiting nerve root. Entirely extradural lesions with no bone involvement are rare and represent about 12% of all intraspinal hemangiomas.

The magnetic resonance imaging showed an extramedullary, extradural space occupative lesion on the right side of the spinal canal from D5 to D7 vertebral levels. The mass was well marginated and there was no bone involvement. Compression of the adjacent thecal sac was observed, with displacement to the left side. Radiological differential diagnosis included nerve sheath tumor and meningioma. The patient underwent D6 hemilaminectomy under general anesthesia. Intraoperatively, the tumor was purely extradural in location with mild extension into the right foramina. No attachment to the nerves or dura was found. Total excision of the extradural compressing mass was possible as there were preserved planes all around. Histopathology revealed cavernous hemangioma. As illustrated in our case, purely epidural hemangiomas, although uncommon, ought to be considered in the differential diagnosis of spinal epidural soft tissue masses. Findings that may help to differentiate this lesion from the ubiquitous disk prolapse, more common meningiomas and nerve sheath tumors are its ovoid shape, uniform T2 hyperintense signal and lack of anatomic connection with the neighboring intervertebral disk or the exiting nerve root. Entirely extradural lesions with no bone involvement are rare and represent about 12% of all intraspinal hemangiomas.

    Frontal and temporal language areas involved in syntactic processing are connected by several dorsal and ventral tracts, but the functional roles of the different tracts are not well understood. To identify which white matter tract(s) are important for syntactic processing, we examined the relationship between white matter damage and syntactic deficits in patients with primary progressive aphasia, using multimodal neuroimaging and neurolinguistic assessment. Diffusion tensor imaging showed that microstructural damage to left hemisphere dorsal tracts--the superior longitudinal fasciculus including its arcuate component--was strongly associated with deficits in comprehension and production of syntax. Damage to these dorsal tracts predicted syntactic deficits after gray matter atrophy was taken into account, and fMRI confirmed that these tracts connect regions modulated by syntactic processing. In contrast, damage to ventral tracts--the extreme capsule fiber system or the uncinate fasciculus--was not associated with syntactic deficits. Our findings show that syntactic processing depends primarily on dorsal language tracts.

    Full Text Available A seismic velocity analysis from teleseismic receiver functions recorded in the southwestern fank of the Sierra de Pie de Palo (Western Sierras Pampeanas, Argentina, is compared with seismic properties directly calculated from lithological composition. The seismological results show an upper layer located in the first 13 km depth. A deeper contrast in seismic velocities is found at a depth of 28 km; the petrological results indicate a composition compatible with observed greenschist and amphibolite facies mafic rocks up to this depth. The receiver function measurements at 13 km and 28 km depths could be interpreted as two potential décollement levels that might have favoring a mechanism to thicken the whole crust, which produces a receiver function Moho signal located at 47 km depth. In addition, the lower crust between 28 km and 47 km exhibits high seismic P-wave velocities and Vp/Vs ratio (> 1.80 that are representative of a densification consistent with upper amphibolite to granulite/ecoglite facies lithologies. Based on these results, the combined petrological and seismological analyses suggest the continuation of the same mafic-crust outcropping lithologies into the lower levels of the 47-km thickened crust, which could be part of the Pie de Palo Complex ophiolite belt or the Precordillera basement.Un análisis de funciones del receptor registradas en el suroeste de la Sierra de Pie de Palo (Sierras Pampeanas Occidentales, Argentina, se compara con propiedades sísmicas directamente calculadas a partir de la composición litológica.

    Arthroscopic treatments of meniscal injuries of the knee are among the most common orthopaedic procedures performed. Adequate visualization of the posterior horn of the medial meniscus might be challenging, especially in patients with tight medial compartments. In these cases instrument manipulation in an attempt to reach the posterior horn of the meniscus can cause an iatrogenic chondral injury because of the narrow medial joint space. A transcutaneous medial collateral ligament (MCL) pie-crusting release facilitates expansion of the medial joint space in a case of a tight medial compartment. Nevertheless, it might cause injury to the superficial MCL, infection, and pain and injury to the saphenous nerve because of multiple needle punctures of the skin. We describe an inside-out, arthroscopic deep MCL pie-crusting release, which allows access to the medial meniscus through the anterior approach to provide good visualization of the footprint and sufficient working space.

    2011-01-01

    To determine the influence of pairing status on dawn singing behaviour in pied bush chats Saxicola caprata, we conducted mate removal experiments across eight territories. The experiment was divided into three stages: pre-removal (pairs were present on theit respective territories), removal (females were experimentally removed), and returned (females were released into the focal pairs' territories). Dawn bout length, song rate, song complexity, percentage performance time, song perch height, and distance of singing location to territory boundary were measured for each male during each experimental stage. We did not find an effect of mate removal on any dawn song characteristics of male pied bush chats suggesting that the presence or absence of a mate does not influence male dawn singing behaviour. Our findings further suggest that males use dawn chorus to mediate social relationships with neighbouring males to proclaim an established territory.

    An outbreak of listeriosis in England affecting 14 people between 2010 and 2012 and linked to the consumption of pork pies was investigated. All 14 individuals were older than 55 years, 12 were men, and 10 reported the presence of an underlying condition. All were resident in or had visited either of two English regions and were infected with the same strain of Listeria monocytogenes. In interviews with 12 patients, 9 reported eating pork pies, and individuals that consumed pork pies were significantly more likely to be infected with an outbreak strain than were individuals with sporadic cases of listeriosis infections in England from 2010 to 2012. Pork pies were purchased from seven retailers in South Yorkshire or the East Midlands, and the outbreak strain was recovered from pork pies supplied by only the producer in South Yorkshire. The outbreak strain was also recovered from samples of finished product and from environmental samples collected from the manufacturer. The likely source of contamination was environmental sites within the manufacturing environment, and the contamination was associated with the process of adding gelatin to the pies after cooking. Inadequate temperature control and poor hygienic practices at one of the retailers were also identified as possible contributory factors allowing growth of the pathogen. Following improvements in manufacturing practices and implementation of additional control measures at the retailers' premises, L. monocytogenes was not recovered from subsequent food and environmental samples, and the outbreak strain was not detected in further individuals with listeriosis in England.

  10. Tunable PIE and synchronized gating detections by FastFLIM for quantitative microscopy measurements of fast dynamics of single molecules

    The crosstalk between two fluorescent species causes problems in fluorescence microscopy imaging, especially for quantitative measurements such as co-localization, Förster resonance energy transfer (FRET), fluorescence cross correlation spectroscopy (FCCS). In laser scanning confocal microscopy, the lasers can be switched on and off by acousto-optic tunable filters (AOTF) in the microsecond scale for alternative line scanning in order to avoid the crosstalk while minimizing the time delay between two lasers on the same pixel location. In contrast, the pulsed interleaved excitation (PIE) technique synchronizes two pulsed lasers of different wavelengths in the nanosecond scale to enable measuring superfast dynamics of two fluorescent species simultaneously and yet quantitatively without the crosstalk contamination. This feature is critical for many cell biology applications, e.g. accurate determination of stoichiometry in FRET measurements for studying protein-protein interactions or cell signal events, detection of weaker bindings in FCCS by eliminating the false cross correlation due to the crosstalk. The PIE has been used with the time correlated single photon counting (TCSPC) electronics. Here, we describe a novel PIE development using the digital frequency domain (DFD) technique -- FastFLIM, which provides tunable PIE setups and synchronized gating detections, tailored and optimized to specific applications. A few PIE setups by FastFLIM and measurement examples are described. Combined with the sensitivity of Alba and Q2 systems, the PIE allowed us to quantitatively measure the fast dynamics of single molecules.

    The main aims of this study are to describe the characteristics of the meat pie, a typical product of the regional gastronomy of Murcia and to determine its nutritional and energy values, fatty acid profile and fat quality. There were studied 24 samples of Murcia's meat pie from the six best-selling retail establishments in this Region (four units per establishment).The moisture, protein, fat, carbohydrates, fibre and minerals, contents and the energy value, fatty acid profile and fat quality were analyzed using the Official Analysis Methods of Foods. All analyses were performed by triplicate. The average weight of this product was 192.3 ± 11.8 g, with three differentiated parts (base, filling and pastry lid). All ingredients were natural raw materials: wheat flour, lard, ground beef, sliced boiled egg and chorizo, water and spices (salt, pepper, garlic, paprika and nutmeg). Most of its organoleptic attributes are due to the type and amount of fat or lard. The combination of the other ingredients and the particular formulation of the spices are also responsible of other attributes. Due to its protein content (11.0%), this meat pie can replace other meat dishes, and be incorporated into a balanced diet. However, it is necessary to take into account its fat and energy contents (17.3 g and 317 kcal/100 g, respectively). Unlike many common pastry products, it contains no trans fatty acids. The results of the research show that the studied product remains, at present, an artisan food, and offer reliable information that it is representative of the energy and nutritional values of the Murcia's meat pie, a typical product of the gastronomy of the Region of Murcia.

    In this report, techniques, equipment and hot-cell facilities for PIE were introduced to observe behavior of particle for the safety and stability based on the open literatures. In order to analyse fuel stability, failure of coated layers and behavior of boundaries between layers are examined, and the analytical results gives feedback information to manufacturing process of the particles. On the other hand, the test for the release of fission products is carried out at high temperature for measurement of diffusivity. For PIE of fuel particle, a lot of experimental development and modification of equipment has to be made in our facilities as well as installation and operation in hot cell facility. The IMGA(Irradiated Microsphere Gamma Analyzer) technique needs to be developed for radioisotope analysis of particle to observe fuel failure. KUFA system is necessary to obtain release data of fission products from the fuel kernel and to observe interactions between kernel and coating layers. In addition, some specific techniques for the material properties such as nano-indentation, x-ray radiography and so on. Optical microscope, SEM and EPMA may be possible to perform PIE of fuel particle for microstructure analysis. ICP-AES and ICP-MS are also available for chemical analysis. Some techniques, for example, deconsolidation of fuel compact, should be obtained by technical papers and experts from overseas.

    Post-irradiation examination (PIE) is being performed in support of tristructural isotropic (TRISO) coated particle fuel development and qualification for High-Temperature Gas-cooled Reactors (HTGRs). AGR-1 was the first in a series of TRISO fuel irradiation experiments initiated in 2006 under the Advanced Gas Reactor (AGR) Fuel Development and Qualification Program; this work continues to be funded by the Department of Energy's Office of Nuclear Energy as part of the Advanced Reactor Technologies (ART) initiative. AGR-1 fuel compacts were fabricated at Oak Ridge National Laboratory (ORNL) in 2006 and irradiated for three years in the Idaho National Laboratory (INL) Advanced Test Reactor (ATR) to demonstrate and evaluate fuel performance under HTGR irradiation conditions. PIE is being performed at INL and ORNL to study how the fuel behaved during irradiation, and to examine fuel performance during exposure to elevated temperatures at or above temperatures that could occur during a depressurized conduction cooldown event. This report summarizes safety testing of irradiated AGR-1 Compact 5-1-1 in the ORNL Core Conduction Cooldown Test Facility (CCCTF) and post-safety testing PIE.

    Full Text Available The aim was to evaluate the feeding behavior, carcass characteristics and meat quality of Nelore heifers fed sunflower pie replacing cottonseed meal. They were used 30 heifers with average initial weight of 274 kg ± 28 kg and average age of 24 months, confined for 76 days. The design was completely randomized with five treatments (0, 150, 300, 450 and 600 g kg-1 DM and six replicates per treatment. By completing 24 hours after slaughter, it evaluated muscle conformation and degree of finish made the longissimus dorsi at the 13th rib. A representative sample between the 10th and 12th ribs was collected for evaluation of the physical components of carcasses. As well as the other variables, the hot carcass weight, dressing percentage, carcass length and rib eye area were not influenced by different pie levels in feed. The mean percentage of muscle, bone and fat from the carcass were 53.45; 16.14 and 29.46%, respectively, similar among treatments. Therefore, the use of up to 600 g kg-1 of sunflower pie replacing cottonseed meal as the main protein source, did not affect the carcass characteristics and meat quality of Nelore heifers.

    Full Text Available La chute de plain-pied reste un accident du travail fréquent et grave. La terminologie qualifiant ces accidents est variée, relativement imprécise et n’intègre pas la diversité des accidents rencontrés sous les différentes appellations. L’intérêt de considérer une catégorie d’accidents du travail avec perturbation du mouvement (APM est tout d’abord mis en évidence à partir de divers extraits de récits d’accidents. Un modèle est ensuite proposé pour les APM montrant que, dans ces cas particuliers d’accident la blessure est souvent la conséquence de l’association fortuite entre l’énergie du mouvement perturbé de la victime et un élément matériel rendu blessant de par ses propriétés et appelé a posteriori un « danger circonstanciel ». Enfin, le raisonnement qui sous-tend la classification de ces accidents est explicité. Il apparaît notamment que la prévention ciblant les causes immédiates de la blessure est difficile voire impossible dans les cas d’APM en raison principalement des exigences inhérentes au travail et de contraintes que ferait peser sur l’entreprise l’application de cette prévention. La prévention à la source du risque tend alors à devenir la seule possible. Ainsi, de banal, l’APM devient un révélateur de dysfonctionnements au sein du système de production.Falls on the same level remain frequent and serious occupational accidents. The terminology used to describe these accidents is varied and somewhat imprecise. Moreover it does not integrate the variety of accidents with different names. The advantage of considering an occupational accident category with motion perturbation (MPA is demonstrated, based on extracts from various occupational accident accounts. A model is then proposed for MPAs that shows that in these specific cases of accidents, the injury often results from a fortuitous association between the victim’ perturbed motion energy and a physical element that

  4. Inhibition of transcription by the Caenorhabditis elegans germline protein PIE-1: genetic evidence for distinct mechanisms targeting initiation and elongation.

    Ghosh, Dolan; Seydoux, Geraldine

    2008-01-01

    In Caenorhabditis elegans embryos, specification of the germ lineage depends on PIE-1, a maternal protein that blocks mRNA transcription in germline blastomeres. Studies in mammalian cell culture have suggested that PIE-1 inhibits P-TEFb, a kinase that phosphorylates serine 2 in the carboxyl-terminal domain (CTD) repeats of RNA polymerase II during transcriptional elongation. We have tested this hypothesis using an in vivo complementation assay for PIE-1 function. Our results support the view that PIE-1 inhibits P-TEFb using the CTD-like motif YAPMAPT. This activity is required to block serine 2 phosphorylation in germline blastomeres, but unexpectedly is not essential for transcriptional repression or specification of the germline. We find that sequences outside of the YAPMAPT are required to inhibit serine 5 phosphorylation, and that this second inhibitory mechanism is essential for transcriptional repression and specification of the germ lineage. Our results suggest that PIE-1 uses partially redundant mechanisms to block transcription by targeting both the initiation and elongation phases of the transcription cycle.

    Rhodopsin self-associates in the plasma membrane. At low concentrations, the interactions are consistent with a monomer-dimer equilibrium (Comar et al., J Am Chem Soc 136(23):8342-8349, 2014). At high concentrations in native tissue, higher-order clusters have been observed (Fotiadis et al., Nature 421:127-128, 2003). The physiological role of rhodopsin dimerization is still being investigated, but it is clear that a quantitative assessment is essential to determining the function of rhodopsin clusters in vision. To quantify rhodopsin interactions, I will outline the theory and methodology of a specialized time-resolved fluorescence spectroscopy for measuring membrane protein-protein interactions called pulsed-interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS). The strength of this technique is its ability to quantify rhodopsin interactions in situ (i.e., a live cell plasma membrane). There are two reasons for restricting the scope to live cell membranes. First, the compositional heterogeneity of the plasma membrane creates a complex milieu with thousands of lipid, protein, and carbohydrate species. This makes it difficult to infer quaternary interactions from detergent solubilized samples or construct a model phospholipid bilayer that recapitulates all of the interactions present in native membranes. Second, organizational structure and dynamics is a key feature of the plasma membrane, and fixation techniques like formaldehyde cross-linking and vitrification will modulate the interactions. PIE-FCCS is based on two-color fluorescence imaging with time-correlated single-photon counting (TCSPC) (Becker et al., Rev Sci Instrum 70:1835-1841, 1999). By time-tagging every detected photon, the data can be analyzed as a fluorescence intensity distribution, fluorescence lifetime histogram, or fluorescence (cross-)correlation spectra (FCS/FCCS) (Becker, Advanced time-correlated single-photon counting techniques, Springer, Berlin, 2005). These

    A microsporidian infection was diagnosed in a pied peach-faced lovebird (Agapornis roseicollis) which had died after an illness of 2 days. The parasite was observed in the liver, kidney, and small intestine. Lesions were most severe in the liver, with numerous organisms adjacent to areas of hepatic necrosis. Although the organisms were seen within renal tubules and within the intestinal mucosa, inflammatory lesions in those sites were minimal. The microsporidian nature of the parasite was confirmed by morphologic studies. The genus of the organism was not determined.

             These asymmetries will be accounted for within Fox and Pesetsky's (2003, 2005 cyclic linearization model, which requires non-string-vacuous movement to proceed through the left edge of Spell-out domains, deriving cross-linguistic variation as to Negative Shift from differences in the availability of these left-edge positions. Thereby, pied-piping is considered a last resort strategy, possible only if the prepositional complement cannot undergo Negative Shift on its own due to the unavailability of the relevant left-edge position.

  9. Spatial distribution of breeding Pied Flycatchers Ficedula hypoleuca in respect to their natal sites

    2004-06-01

    Full Text Available Study of philopatry and dispersal of pied flycatchers Ficedula hypoleuca was launched on the Courish Spit (SE Baltic in 1981. Since then, ca. 9,000 nestlings were ringed at different sites in the Russian part of the Courish Spit. A total of 557 individuals ringed as pulli were recaptured in subsequent seasons in the study area. Both males and females are more often recaptured in the plots where they were ringed than in other plots. These results were interpreted in the framework of the hypothesis forwarded by Löhrl (1959 and supported by Berndt & Winkel (1979. These authors suggested that cavity nesters (pied flycatchers and collared flycatchers F. albicollis imprint their future local breeding area during the period of postfledging exploration. Birds that survive until the next spring, return to these imprinted areas to breed. A similar study done by Sokolov et al. (1984 on the Courish Spit in an open nesting species, the chaffinch Fringilla coelebs, confirmed this finding. We assumed that juvenile pied flycatchers disperse for varying distances during their postfledging movements and imprint a local area, some 1–5 kilometres in diameter. This area is the goal of their migration next spring. It is suggested that in spring, yearlings are non–randomly distributed in respect to the area they have imprinted as juveniles. Recently, Vysotsky (2000, 2001 re–analysed the same data on philopatry of pied flycatchers on the Courish Spit and forwarded an alternative hypothesis. He suggests that juveniles, both males and females, do not imprint any local area during the postfledging period, but are distributed randomly across the area of several dozens of kilometres in spring. Vysotsky was able to show that distribution of distances of natal dispersal did not differ from the random pattern the study plot which was an 8.5 km long line of nest boxes along the Courish Spit. The aim of this study was to test these two alternative hypotheses. To do so, we

    2017-03-01

    Full Text Available The study of pristine preserved shells of Mesozoic Ammonoidea shows different types of construction and formation of the dorsal shell wall. We observe three major types: (i The vast majority of Ammonoidea, usually planispirally coiled, has a prismatic reduced dorsal shell wall which consists of an outer organic component (e.g., wrinkle layer, which is the first layer to be formed, and the subsequently formed dorsal inner prismatic layer. The dorsal mantle tissue suppresses the formation of the outer prismatic layer and nacreous layer. With the exception of the outer organic component, secretion of a shell wall is omitted at the aperture. A prismatic reduced dorsal shell wall is always secreted immediately after the hatching during early teleoconch formation. Due to its broad distribution in (planispiral Ammonoidea, the prismatic reduced dorsal shell wall is probably the general state. (ii Some planispirally coiled Ammonoidea have a nacreous reduced dorsal shell wall which consists of three mineralized layers: two prismatic layers (primary and secondary dorsal inner prismatic layer and an enclosed nacreous layer (secondary dorsal nacreous layer. The dorsal shell wall is omitted at the aperture and was secreted in the rear living chamber. Its layers are a continuation of an umbilical shell doubling (reinforcement by additional shell layers that extends towards the ventral crest of the preceding whorl. The nacreous reduced dorsal shell wall is formed in the process of ontogeny following a prismatic reduced dorsal shell wall. (iii Heteromorph and some planispirally coiled taxa secrete a complete dorsal shell wall which forms a continuation of the ventral and lateral shell layers. It is formed during ontogeny following a prismatic reduced dorsal shell wall or a priori. The construction is identical with the ventral and lateral shell wall, including a dorsal nacreous layer. The wide distribution of the ability to form dorsal nacre indicates that it is

    The pie-crusting method of ligament and tendon lengthening has been used successfully in various tissues but is not reported in the literature as an option for patellar or quadriceps tendons to address flexion limitation. Our case report discusses a patient with longstanding flexion limitation who underwent primary total knee arthroplasty. The report reviews the literature on intraoperative treatments, which primarily pertains to the condition of patella baja, and demonstrates that the pie-crusting technique should be included as a treatment option for a tight extensor mechanism while having some advantages over tibial tubercle osteotomy or Z-plasty.

    Full Text Available Case summary A 2-month-old, male kitten was presented for evaluation of unilateral blepharospasm and epiphora involving the right eye. Ocular examination revealed conjunctivitis, a superficial corneal ulcer, reflex anterior uveitis and a haired mass within the dorsal cornea of the right eye. The mass was subsequently removed surgically via a lamellar keratectomy. Histologic evaluation of the mass via light microscopy revealed it to be comprised of normal-haired skin with mild inflammation. One week after surgical removal and medical management of the corneal ulcer, all ocular clinical signs had resolved with minimal corneal scarring. On re-examination 6 months following surgical excision of the mass, the kitten was noted to be comfortable with no significant corneal scarring. Relevance and novel information To our knowledge, this is the first case report of a dorsally located corneal dermoid in a cat.

    Sugar-rich food waste is a sustainable feedstock that can be converted into ethanol without an expensive thermochemical pretreatment that is commonly used in first and second generation processes. In this manuscript we have outlined the pie waste conversion to ethanol through a two-step process, namely, enzyme hydrolysis using commercial enzyme products mixtures and microbial fermentation using yeast. Optimized enzyme cocktail was found to be 45% alpha amylase, 45% gamma amylase, and 10% pectinase at 2.5mg enzyme protein/g glucan produced a hydrolysate with high glucose concentration. All three solid loadings (20%, 30%, and 40%) produced sugar-rich hydrolysates and ethanol with little to no enzyme or yeast inhibition. Enzymatic hydrolysis and fermentation process mass balance was carried out using pie waste on a 1000g dry weight basis that produced 329g ethanol at 20% solids loading. This process clearly demonstrate how food waste could be efficiently converted to ethanol that could be used for making biodiesel by reacting with waste cooking oil. Copyright © 2017 Elsevier Ltd.

    On June 6, 2007, a cluster of four human Salmonella serotype I 4,5,12:i:-* infections sharing a pulsed-field gel electrophoresis (PFGE) pattern was identified by the Pennsylvania Department of Health and reported to PulseNet. Initial investigations conducted during June--September 2007 by state and local health departments in collaboration with CDC did not identify a source of infection. This report summarizes the results of subsequent investigations of the outbreak, which determined that 401 cases of salmonellosis occurred in 41 states during 2007, with 32% of ill persons hospitalized. A multistate case-control study conducted during October 3-13 indicated that illness was associated with consumption of Banquet brand frozen, not-ready-to-eat pot pies (odds ratio = 23.6; poutbreak strain was isolated from 13 samples of unopened Banquet pot pies collected from the homes of patients. This outbreak highlights the need to cook not-ready-to-eat frozen foods thoroughly; these products should be clearly labeled as requiring complete cooking, and cooking instructions should be validated to account for variability in microwave wattage and common misconceptions among consumers regarding the nature of not-ready-to-eat foods.

    Survival is one of the most central population measures when the effects of the pollution are studied in natural bird populations. However, only few studies have actually measured rigorous survival estimates on adult birds. In recent years there has been a methodological advance in survival analyses by mark-recapture models. We modelled local survival (including mortality and emigration) with the program MARK in a population of a small insectivorous passerine bird, the pied flycatcher (Ficedula hypoleuca), around a point source of heavy metals. The local survival of females in the polluted area was about 50% lower than in the other areas. Males, however, survived relatively well in the heavily polluted area, but showed somewhat lower survival in the moderately polluted area. Different pollution effects between two sexes might be due to pollution-related differences in reproductive effort in females and males, and/or more intensive uptake of heavy metals by laying females. - Female pied flycatchers (Ficedula hypoleuca) show decreased local survival around a copper smelter.

    Many family characteristics were reported to increase the risk of bipolar disorder (BPD). The development of BPD may be mediated through different pathways, involving diverse risk factor profiles. We evaluated the associations of family characteristics to build influential causal-pie models to estimate their contributions on the risk of developing BPD at the population level. We recruited 329 clinically diagnosed BPD patients and 202 healthy controls to collect information in parental psychopathology, parent-child relationship, and conflict within family. Other than logistic regression models, we applied causal-pie models to identify pathways involved with different family factors for BPD. The risk of BPD was significantly increased with parental depression, neurosis, anxiety, paternal substance use problems, and poor relationship with parents. Having a depressed mother further predicted early onset of BPD. Additionally, a greater risk for BPD was observed with higher numbers of paternal/maternal psychopathologies. Three significant risk profiles were identified for BPD, including paternal substance use problems (73.0%), maternal depression (17.6%), and through poor relationship with parents and conflict within the family (6.3%). Our findings demonstrate that different aspects of family characteristics elicit negative impacts on bipolar illness, which can be utilized to target specific factors to design and employ efficient intervention programs.

    The goal of doctor of nursing practice (DNP) programs should be to produce nurses that are uniquely prepared to bridge the gap between the discovery of new knowledge and the scholarship of translation, application, and integration of this new knowledge in practice (American Association of Colleges of Nursing [AACN], 2006). However, there is concern over the variability in DNP programs and expected outcomes. The aim of this article is to describe a 5-point system of evaluation to determine whether a DNP final project meets the outcomes of the AACN Essentials of Doctoral Education in Advanced Nursing Practice (2006) in a comprehensive and rigorous way. In brief, the five criteria that must be met are represented by the acronym EC as PIE (E = Enhances; C = Culmination; P = Partnerships; I = Implements; E = Evaluates). Each criterion must be present and come together to form one complete "pie" representing evidence-based practice that is robust and innovative, culminating in a rigorous doctoral level DNP final project. In addition, we provide detailed examples of how these standards are currently being successfully implemented and discuss additional possibilities.

    Post-irradiation examination (PIE) is being performed in support of tristructural isotropic (TRISO) coated particle fuel development and qualification for High Temperature Gas-cooled Reactors (HTGRs). This work is sponsored by the Department of Energy Office of Nuclear Energy (DOE-NE) through the Advanced Reactor Technologies (ART) Office under the Advanced Gas Reactor Fuel Development and Qualification (AGR) Program. The AGR-1 experiment was the first in a series of TRISO fuel irradiation tests initiated in 2006. The AGR-1 TRISO particles and fuel compacts were fabricated at Oak Ridge National Laboratory (ORNL) in 2006 using laboratory-scale equipment and irradiated for 3 years in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) to demonstrate and evaluate fuel performance under HTGR irradiation conditions. Post-irradiation examination was performed at INL and ORNL to study how the fuel behaved during irradiation, and to test fuel performance during exposure to elevated temperatures at or above temperatures that could occur during a depressurized conduction cooldown event. This report summarizes safety testing and post-safety testing PIE conducted at ORNL on loose particles extracted from irradiated AGR-1 Compact 4-4-2.

    Full Text Available This article explores the meanings embedded in the production, consumption, and symbolic positioning of turkey and pumpkin pie, foods closely associated with the American ritual feast of Thanksgiving. An analysis of turkey and pumpkin pie recipes used and adapted by first- and second-generation immigrants in north America, and by north Americans living abroad, throws into relief complex relations between food production, food consumption and the complexities of lived and often multiple sociocultural identifications. Through sharing the experiences, memories and associations evoked by individuals in the production of holiday recipes, I argue that ideas about ‘tradition’ and a desire to celebrate family and community through the ritual of baking, serving and consuming a ‘standard’ Thanksgiving holiday meal allow one to feel part of an imagined global American community. At the same time these details demonstrate celebration of individual and familial distinctiveness that is traced to (sometimes contested memories of childhood and/or ethnic background, as well as to exploration, innovation and experience in the world at large through travel, migration and imagination.

  3. Fos, nociception and the dorsal horn.

    Science.gov (United States)

    Coggeshall, Richard E

    2005-12-01

    The protooncogene c-fos is rapidly activated after noxious stimuli to express the protein Fos in spinal dorsal horn neurons that are in the 'correct' locations for nociceptive information transfer. As such, therefore, mapping Fos expression in these neurons is at present the best global marker for efficiently locating populations of neurons in the awake animal that respond to nociceptive input. This allows, among other things, precise behavioral measurements to be correlated with Fos expression. Two arenas where mapping dorsal horn Fos expression has made a major impact are in the anatomy of nociceptive systems and as a useful assay for the analgesic properties of various therapeutic regimens. Also Fos expression is the only way to map populations of neurons that are responding to non-localized input such as withdrawal after addiction and vascular occlusion. Another insight is that it shows a clear activation of neurons in superficial 'pain-processing' laminae by innocuous stimuli after nerve lesions, a finding that presumably bears on the allodynia that often accompanies these lesions. It is to be understood, however, that the Fos localizations are not sufficient unto themselves, but the major function of these studies is to efficiently locate populations of cells in nociceptive pathways so that powerful anatomic and physiologic techniques can be brought to bear efficiently. Thus, the purpose of this review is to summarize the studies whose numbers are geometrically expanding that deal with Fos in the dorsal horn and the conclusions therefrom.

    The environment around metal industries, such as smelters, is often highly contaminated due to continuous deposition of metals. We studied nest box breeding populations of pied flycatchers (Ficedula hypoleuca) in a well-studied pollution gradient from a sulfide ore smelter in Northern Sweden, after reduced aerial metal emissions (by 93-99%) from the smelter. The deposition of arsenic, cadmium, copper and zinc (based on moss samples) reflected the reduced emissions fairly well. However, nestling pied flycatchers had similar concentrations of these elements and mercury in tissues (bone, liver and blood) and feces in the 2000s, as in the 1980s, when the emissions were substantially higher. The exposure to high metal concentrations in the close vicinity of the smelter resulted in inhibited ALAD activities, depressed hemoglobin and hematocrit levels and increased mortality of nestlings. Our results indicate that in the highly contaminated environment around the smelter, nestlings reflected the slowly cycling soil pool, rather than the atmospheric deposition, and the concentration in soils plays an important role for the response of pied flycatchers to reduced atmospheric deposition. - Highlights: {yields} Pied flycatchers were studied in a pollution gradient from a sulfide smelter. {yields} Metal emissions from the smelter have decreased substantially. {yields} Nestling birds still had high metal concentrations in tissues. {yields} Health and survival rates of nestlings were negatively affected. {yields} Recovery of birds is not expected in the near future.

    Distribution of BoLA-A antigens and BoLA-DRB3 alleles was studied by means of the microlymphocytotoxic test (BoLA-A) and the PCR-RFLP method (BoLA-DRB3) using restriction endonucleases RSAI, HaeIII, and XhoII in Ayrshire (n = 127) and Black Pied (n = 129) cattle breeds. Comparative analysis of profiles for class I antigens revealed significant differences in the frequencies of antigens W2, W6, W10, W31, W44, W15, and W19 (P > 99%). The studied breeds also differ in the spectrum of BoLA-DRB3 alleles and distribution of their frequencies. Heterogeneous allele frequency profile was detected in Ayrshire cattle: five of 18 detected alleles (DRB3.2*7, *8, *10, *24, and *28) accounted for 77%. Allele DRB3.2*7 (37.6%), which is classed with rare alleles in Black Pied cattle is the most common in Ayrshire cattle. The observed heterozygosity level in the combined sample of Black Pied breed (0.836) is higher than in Ayrshire breed (0.070). In both breeds, the heterozygosity level was studied in the groups of healthy and ill with persistent lymphocytosis (caused by bovine leukemia virus) animals and in the group of virus carriers in Ayrshire breed. In ill animals, a decrease in the observed heterozygosity level was detected, as compared to healthy animals and the expected heterozygosity level. The observed heterozygosity level exceeds the expected one in virus carriers. The detected features of the heterozygosity level in the studied groups allow the heterozygosity level for locus BoLA-DRB3 to be considered a nonspecific factor of resistance to leukemia and are heterozygous animals to have higher resistance to bovine leukemia. The presence of a larger proportion of highly productive animals (the annual productivity of more than 7000 kg) in the group of ill Ayrshire cattle animals, as compared to healthy animals to established. To increase resistance to bovine leukemia, the obtained data indicate the importance of the control of heterozygosity level and genetic diversity for

    In this review,we describe the current models of dorsal and ventral streams in vision,audition and touch.Available theories take their first steps from the model of Milner and Goodale,which was developed to explain how human actions can be efficiently carried out using visual information.Since then,similar concepts have also been applied to other sensory modalities.We propose that advances in the knowledge of brain functioning can be achieved through models explaining action and perception patterns independently from sensory modalities.

    Full Text Available En este trabajo se muestran resultados relacionados con la estructura de corteza en la región de la sierra de Pie de Palo perteneciente a las Sierras Pampeanas Occidentales a partir de funciones del receptor telesísmicas para la estación sismológica Coronel Fontana (31,605°S y 68,238°O. Estos resultados ponen de manifiesto evidencias de dos discontinuidades intracorticales a profundidades de 13 y 28 km aproximadamente y una discontinuidad más profunda cerca de 47 km de profundidad que correspondería al Moho. Los valores de contraste entre las velocidades de ondas P y S (Vp/Vs para estas discontinuidades son en general elevados. En particular, la región comprendida entre 13 y 28 km de profundidad muestra los valores más altos de Vp/Vs lo cual indicaría un mayor grado de fracturación o fallamiento para esta zona de la corteza. Los resultados indican una densificación de la corteza inferior.

    1989-11-01

    This study investigated the effects of teaching a metacognitive text structure strategy upon the paragraph writing skills of eighth-grade students with learning disabilities. The technique, called Statement-Pie (Hanau, 1974), teaches students to understand the relationship of supporting details to a main idea. Four students were taught to use an outline as a paragraph planning guide, which they then used to convert information into written expository paragraphs. All subjects reached instructional outcome criterion on the writing of comparison/contrast and sequence paragraphs. One week after reaching mastery in the special education classroom, students generalized their paragraph writing skills to other teachers and to different classrooms. The results of this investigation indicate that when provided with direct, intensive instruction in a text structure strategy, adolescents with learning disabilities can improve their skills in paragraph writing.

  16. Population number and distribution of oriental pied hornbill in Guangxi, China

    Full Text Available The oriental pied hornbill (Anthracoceros albirostris albirostris is a State Protected Species and also an important seed dispersal agent in Tropical Asia. Recent studies show that the range of oriental piedhornbill in Guangxi has decreased significantly in the last decades. During the 1970s the species was widespread along the Sino-Vietnamese border but since the 2000s it has been confined to only three isolated areas. Although the population has declined substantially, Xidamingshan still supports the largest hornbill population known in Guangxi. In order to understand the current status of the species in Guangxi, China, we conducted a simultaneous population survey in Xidamingshan Nature Reserve in 2009. At least, fifty birds were recorded during survey and 124 plant species are identified as potential food source of the bird. Human disturbance and hunting are the main threats to the species in Guangxi. Further research and conservation of the species are urgently required.

    Balancing a varus knee is traditionally accomplished by releasing the medial soft-tissue sleeve off the tibia. Recently, "pie-crusting" (PC) medial structures has been described. In a biomechanical cadaver study we compared PC to traditional release (TR) to determine their effects on flexion and extension gaps. PC was done in five specimens along the anterior half of the medial soft-tissue sleeve and five along the posterior half, followed by a traditional release. In 90° flexion, valgus laxity after TR was significantly greater than after PC alone. PC of the anterior or posterior aspect of the medial soft-tissue sleeve can effect changes more in flexion than in extension, respectively. Complete TR did not provide more gap opening than PC in extension, but produced more effect in flexion.

  18. Variable step size and order strategy for delay differential equations in PIE(CIE)s mode

    Aziz, Nurul Huda Abdul; Majid, Zanariah Abdul

    2014-12-01

    This article deals with the strategy of variable step size and variable order implementation that has been formulated for solving first order of delay differential equations. This strategy is adapted in PIE(CIE)s mode which is generally based on predictor-corrector scheme in multistep block method of order 4 to 9 with s is for convergence test. The purpose here is to enhance the efficiency of the developed predictor-corrector algorithm in the capability to vary automatically not only for the step size, but the order of the method employed as well. All order and coefficients are stored in the code in order to avoid an expensive computational work. The delay argument would be evaluated using Newton divided-difference interpolation at which the points involved would be similar to the current order of the method. Illustrative examples are included to demonstrate the validity and applicability of the presented strategy and comparison is made with the existing results.

    Salmonella and Yersinia are important enteropathogens in poultry and can affect birds of all ages, including embryos. These food-borne zoonotic enteropathogens are of great economic and medical concern worldwide and are intensely studied in poultry. Information regarding the prevalence of these bacteria in wild birds is scarce and biased toward avian species ecologically linked to humans, which have often been incriminated as both reservoirs and disseminators of these enteropathogens. The prevalence of Salmonella and Yersinia recovered from both the feces and eggs in a population of female pied flycatchers (Ficedula hypoleuca) breeding in nest-boxes in central Spain was evaluated. Salmonella arizonae was recovered from the feces of one female but was not recovered from eggs. Yersinia was not detected in either the feces or eggs. These results may suggest that Salmonella and Yersinia may be uncommon in this population studied and may indicate that these birds are unlikely reservoirs of Salmonella and Yersinia.

  20. Degradation of song in a species using nesting holes: the Pied Flycatcher Ficedula hypoleuca

    Full Text Available The habitat, but also the nest hole of a hole-nesting species, will degrade the song during transmission. We investigated how the sounds degrade in a sound transmission experiment with the song of the Pied Flycatcher Ficedula hypoleuca (Muscicapidae. Ten different song elements were transmitted to microphones placed inside and outside a nest box. On average, song degradation was much greater inside than outside the nest boxes, especially with respect to excess attenuation and blurring of the song elements. Being inside a nest box therefore strongly reduces a Pied Flycatcher's possibility of detecting and recognizing songs or eavesdropping on singing interactions.O habitat, mas também a cavidade do ninho de uma espécie nidificando em ocos, provoca uma degradação do som durante sua transmissão. Pesquisamos como os sons são degradados num experimento de transmissão sonora usando o canto do pássaro Ficedula hypoleuca (Muscicapidae. Dez elementos diferentes do canto foram enviados para microfones colocados dentro e fora de uma caixa de nidificação. Em média, a degradação do canto foi muito maior dentro do que fora do ninho, particularmente no que diz respeito ao excesso de atenuação e à borrada dos elementos do canto. Estar dentro de uma cavidade de nidificação, portanto, reduz fortemente a capacidade da espécie de detectar e reconhecer cantos ou de interceptar interações vocais.

    Introducción: las fístulas arteriovenosas intradurales dorsales espinales (FAVIDE) son lesiones poco frecuentes y complejas que son subdiagnósticadas y condicionan discapacidad. El objetivo es presentar nuestra experiencia en el manejo endovascular. Métodos: estudio ambispectivo de pacientes con FAVIDE, tratados mediante terapia endovascular (TEV) con n-butil-cianoacrilato en el periodo de 2007 a 2013. Resultados: se incluyeron 15 pacientes con edad media de 37 años. En 12 casos la presentación fue progresiva e insidiosa en un lapso de entre 6 meses y un año, mientras que 3 presentaron hemorragia. La lesión tuvo localización torácica en 73 % de los casos, lumbar en 20 % y cervical en 7 %. Previo al tratamiento observamos discapacidad de grados 5 y 4 en 73 %, y 67 % tenían alteraciones de la micción de grado 3. Como complicaciones, solo una paciente tuvo deterioro del estado de alerta transitorio 6 horas después del procedimiento. Se encontró una mejoría hacia los grados 1 y 2 de discapacidad, a las 48 horas, 3 y 6 meses, de 53 %, 73 % y 87 %, respectivamente. Conclusiones: con la TEV se tiene un tiempo quirúrgico corto, el volumen de hemorragia es bajo y la estancia hospitalaria es corta, respecto de otras técnicas quirúrgicas. La TEV es un procedimiento seguro y con efectividad significativa en el tratamiento de FAVIDE. Esta es la primera serie de casos tratados con TEV en México.

    Full Text Available The ascending serotonergic projections are derived mainly from mesencephalic raphe nuclei. Topographical projections from mesencephalic raphe nuclei to the striatum were examined in the rat by the retrograde transport technique of HRP (horseradish peroxidase. In 29 rats stereotaxically injection of HRP enzyme were performed in dorsal and ventral parts of striatum separately. The extent of the injection sites and distribution of retrogradely labeled neuronal cell bodies were drawed on representative sections using a projection microscope. Following ipsilateral injection of HRP into the dorsal striatum, numerous labeled neurons were seen in rostral portion of dorsal raphe (DR nucleus. In the same level the cluster of labeled neurons were hevier through caudal parts of DR. A few neurons were also located in lateral wing of DR. More caudally some labeled neurons were found in lateral, medial line of DR. In median raphe nucleus (MnR the labeled neurons were scattered only in median portion of this nucleus. The ipsilateral injection of HRP into the ventral region of striatum resulted on labeling of numerous neurons in rostral, caudal and lateral portions of DR. Through the caudal extension of DR on 4th ventricle level, a large number of labeled neurons were distributed along the ventrocaudal parts of DR. In MnR, labeled neurons were observed only in median part of this nucleus. These findings suggest the mesencephalic raphe nuclei projections to caudo-putamen are topographically organized. In addition dorsal and median raphe nuclei have a stronger projection to the ventral striatum.

    Full Text Available Isolated dislocation of the tarsal naviculum is an unusual injury, scarcely reported in the literature. The naviculum is surrounded by the rigid bony and ligamentous support hence fracture dislocation is more common than isolated dislocation. The mechanism and treatment options remain unclear. In this case report, we describe a 31 year old man who sustained an isolated dorsal dislocation of the left tarsal naviculum, without fracture, when he was involved in a motor vehicle collision. The reported mechanism of the dislocation is a hyper plantar flexion force applied to the midfoot, resulting in a transient disruption of the ligamentous support of the naviculum bone, with dorsal displacement of the bone. The patient was treated with open reduction and Krischner-wire fixation of the navicular after the failure of closed reduction. The wires were removed after 6 weeks postoperatively. Physiotherapy for stiffness and midfoot pain was recommended for 2 months. At 6 months postoperatively, limping, midfoot pain and weakness were reported, no X-ray abnormalities were found. The patient returned to his obvious activities with a normal range of motion.

    2013-08-01

    To gain insight into the function of the dorsal fins in white-spotted bamboo sharks (Orectolobiformes: Hemiscyillidae) during steady swimming, data on three-dimensional kinematics and electromyographic recordings were collected. Bamboo sharks were induced to swim at 0.5 and 0.75 body lengths per second in a laminar flow tank. Displacement, lag and angles were analyzed from high-speed video images. Onset, offset, duration, duty cycle and asynchrony index were calculated from three muscle implants on each side of each dorsal fin. The dorsal fins were displaced more laterally than the undulating body. In addition, the dorsal tips had larger lateral displacement than the trailing edges. Increased speed was accompanied by an increase in tail beat frequency with constant tail beat amplitude. However, lateral displacement of the fins and duration of muscle bursts remained relatively constant with increased speed. The range of lateral motion was greater for the second dorsal fin (mean 33.3°) than for the first dorsal fin (mean 28.4°). Bending within the fin was greater for the second dorsal fin (mean 43.8°) than for the first dorsal fin (mean 30.8°). Muscle onset and offset among implants on the same side of each dorsal fin was similar. Three-dimensional conformation of the dorsal fins was caused by interactions between muscle activity, material properties, and incident flow. Alternating bilateral activity occurred in both dorsal fins, further supporting the active role of these hydrofoils in thrust production during steady swimming. The dorsal fins in bamboo sharks are capable of thrust production during steady swimming and do not appear to function as stabilizing structures.

    2014-09-24

    In hand disorders surgical procedures are more and more widely used and often it's necessary to approach the wrist by the dorsal way. Beneath anatomy of this region is well known, there is still room enough to develop new surgical exposure techniques mostly related to physiology and biomechanics. Our goals are to present an innovative surgical dorsal exposure of the wrist, to show its use for different problems solving, and to evaluate its mini-invasive and functional outcome. Our inedited surgical technique is presented. Since November 1999 to February 2008, this technique has been used by the same surgeon in 60 cases for different pathologies and procedures: 14 SNAC-SLAC wrists III-IV treated by proximal row resection and Resurface-Capitate Pyrocarbon Implant (RCPI), 2 Fenton syndromes by bone graft and RCPI, 6 SNACSLAC II by proximal row resection +/- radial styloidectomy, 2 SLAC III by scaphoidectomy and capito-lunate arthrodesis, 12 scapho-lunate recent dissociations by ligamentoplasty (double approach), 4 scapho-lunate inveterate dissociations by Cuenod Saffar-Romano modified technique and 4 by synthetic ligaments, 1 fracture of the scaphoid proximal pole by synthesis-revascularization-S.L.ligament reconstruction, 15 Kienbock's diseases revascularized by II m.c. artery +/- radial osteotomy. Patients have been evaluated at follow up through the DASH disability questionnaire, the Mayo score for the force, ROM, pain, satisfaction grade. Results are good and encouraging for these applications. In conclusion this new technique with its limited exposure permits an early mobilization with a lower risk of stiffness and can be considered mini-invasive.

    , execute location-based subroutines at each grid point and store the results back into the central repository for post-processing. An optional extension of this infrastructure will be to provide a 'ring buffer'-type database infrastructure, such that model results (e.g. test runs made to check parameter dependency or for development) can be visualised and downloaded after completion without submitting them to a permanent storage infrastructure. Data organization Data collected from sensors are archived and classified in distributed sites connected with an open-source software middleware, GSN. Publicly available data are available through common web services and via a cloud storage server (based on Swift). Collocation of the data and processing in the cloud would eventually eliminate data transfer requirements. Execution control logic Execution of the data analysis pipelines (for both the R-based analysis and the Alpine3D simulations) has been implemented using the GC3Pie framework developed by UZH. (https://code.google.com/p/gc3pie/). This allows large-scale, fault-tolerant execution of the pipelines to be described in terms of software appliances. GC3Pie also allows supervision of the execution of large campaigns of appliances as a single simulation. This poster will present the fundamental architectural components of the data analysis pipelines together with initial experimental results.

    Full Text Available Background. Since skin of the dorsal hands is a known site for the development of cutaneous squamous cell carcinoma, an epidemiologic investigation was needed to determine if beachgoers apply sunscreen to the dorsal aspect of their hands as frequently as they apply it to other skin sites. Aim. The aim of the current study was to compare the use of sunscreen on the dorsal hands to other areas of the body during subtropical late spring and summer sunlight exposure at the beach. Materials and Methods. A cross-sectional survey from a convenience sample of beachgoers was designed to evaluate respondent understanding and protective measures concerning skin cancer on the dorsal hands in an environment with high natural UVR exposure. Results. A total of 214 surveys were completed and analyzed. Less than half of subjects (105, 49% applied sunscreen to their dorsal hands. Women applied sunscreen to the dorsal hands more than men (55% women versus 40% men, . Higher Fitzpatrick Skin Type respondents were less likely to protect their dorsal hands from ultraviolet radiation (. Conclusions. More public education focused on dorsal hand protection from ultraviolet radiation damage is necessary to reduce the risk for squamous cell carcinomas of the hands.

Aim. The aim of the current study was to compare the use of sunscreen on the dorsal hands to other areas of the body during subtropical late spring and summer sunlight exposure at the beach. Materials and Methods. A cross-sectional survey from a convenience sample of beachgoers was designed to evaluate respondent understanding and protective measures concerning skin cancer on the dorsal hands in an environment with high natural UVR exposure. Results. A total of 214 surveys were completed and analyzed. Less than half of subjects (105, 49%) applied sunscreen to their dorsal hands. Women applied sunscreen to the dorsal hands more than men (55% women versus 40% men, P = 0.04). Higher Fitzpatrick Skin Type respondents were less likely to protect their dorsal hands from ultraviolet radiation (P = 0.001). Conclusions. More public education focused on dorsal hand protection from ultraviolet radiation damage is necessary to reduce the risk for squamous cell carcinomas of the hands.

    Full Text Available The objective of the research was to evaluate the use of filter pie and phosphate rock enriched with biofertilizer microorganisms on the population of microorganisms and phosphorus tenor in the soil and on plants. The experiment was conducted in a vegetation house with corn plants with Latossolo Red-Distrófico, containing seven treatments disposed in an entirely randomized design, where the treatments were: soil samples and filter pie with additions of phosphate of Araxá rock enriched with microorganisms coming from Biopack (1, Embrafos (2 and Azotofos (3, and without enrichment with microorganisms (4, and three controls, soil just with filter pie (5, soil just with phosphate rock (6 and only soil (7, with three repetitions. Height, stem diameter and number of leaves for plants were evaluated at 14, 28 and 42 days. At the 45 days the dry matters of leafs and roots were evaluated, as the same as populations of the microorganisms and phosphorus tenor in the soil and in the aerial part of the plant. The tenor of soluble phosphorus in the soil and accumulated phosphorous in the aerial part of corn plan were increased by the treatments with filter pie but not higher with filter pie enriched with biofertilizers, so its use isn’t justified. The pie treatments increase the fungus, total and solubilizers bacterial populations in the soil, provoking an increase of the height, diameter, number of leaves and dry matter of corn plants in a Red-Distrófico Latossolo.

    The paper presents a strategy for numerical solving of parametric integral equation system (PIES) for 2D potential problems without explicit calculation of singular integrals. The values of these integrals will be expressed indirectly in terms of easy to compute non-singular integrals. The effectiveness of the proposed strategy is investigated with the example of potential problem modeled by the Laplace equation. The strategy simplifies the structure of the program with good the accuracy of the obtained solutions.

    The kinematics of steady forward swimming of Gymnarchus niloticus is described. The geometric features of the body and locomotive characteristic and parameters of the flexible dorsal fin are discussed. On the basis of observation and experimental data, a simplified kinematic model on loco- motion of the undulatory long dorsal fin propulsion is pro- moted. The hydromechanical performances of the undulatory long dorsal fin propeller of G. Niloticus are estimated with the large-amplitude elongated-body theory. The hydromechani- cal efficiency of the undulatory long dorsal fin system ranged from 81.664% to 86.420% over a speed range of 0.728- 0.985 length·s-1. It is suggested that the undulatory long dorsal fin propulsion is an adaptation to swimming with high hydromechanical efficiency.

    Agenesis of the dorsal pancreas is one of the rare congenital malformations of pancreas. The association of agenesis of the dorsal pancreas with pancreatic tumors is extremely rare and only around 9 cases being reported till date. We report a case of a fifty one year old woman with an agenesis of the dorsal pancreas with periampullary pancreaticobiliary adenocarcinoma. She presented with features of obstructive jaundice without pain abdomen or fever. Laboratory data showed conjugated hyperbilirubinemia, raised alkaline phosphatase and impaired glucose tolerance. Ultrasound abdomen showed periampullary mass. MRI abdomen and MRCP demonstrated dorsal agenesis of the pancreas, dilated intra and extra hepatic bile ducts with narrowing of distal CBD with periampullary mass. Pancreatic tumor was considered as preoperative diagnosis, and pancreaticoduodenectomy was performed. Histopathology confirmed pancreaticobiliary type of adenocarcinoma. A rare case of dorsal agenesis of the pancreas with periampullary pancreaticobiliary type of adenocarcinoma was presented. Therefore this case therefore merits reference as a rare clinical presentation.

    The environment around metal industries, such as smelters, is often highly contaminated due to continuous deposition of metals. We studied nest box breeding populations of pied flycatchers (Ficedula hypoleuca) in a well-studied pollution gradient from a sulfide ore smelter in Northern Sweden, after reduced aerial metal emissions (by 93-99%) from the smelter. The deposition of arsenic, cadmium, copper and zinc (based on moss samples) reflected the reduced emissions fairly well. However, nestling pied flycatchers had similar concentrations of these elements and mercury in tissues (bone, liver and blood) and feces in the 2000s, as in the 1980s, when the emissions were substantially higher. The exposure to high metal concentrations in the close vicinity of the smelter resulted in inhibited ALAD activities, depressed hemoglobin and hematocrit levels and increased mortality of nestlings. Our results indicate that in the highly contaminated environment around the smelter, nestlings reflected the slowly cycling soil pool, rather than the atmospheric deposition, and the concentration in soils plays an important role for the response of pied flycatchers to reduced atmospheric deposition.

    Since proteins have been shown to have the highest satiation-inducing effects of all the macronutrients, increasing the protein level is one of the main strategies for designing foods with enhanced satiating capacity. However, few studies analyze the effect that protein addition has on the texture and flavor characteristics of the target food item to relate it to the expected satiating capacity it elicits. The present work studied cheese pies with three levels of soy and whey proteins. Since the protein level altered the rheological behavior of the batters before baking and the texture of the baked pies, the feasibility of adding several protein levels for obtaining a range of final products was investigated. A check-all-that-apply questionnaire containing 32 sensory and non-sensory characteristics of the samples was given to consumers (n = 131) who also scored the perceived samples' satiating capacity. The results showed that the type and content of protein contributed distinctive sensory characteristics to the samples that could be related to their satiating capacity perception. Harder and drier samples (high protein levels) were perceived as more satiating with less perceptible sweet and milky cheese pie characteristic flavors. Soy contributed an off-flavour. These results will contribute to a better understanding of the interrelation of all these factors, aiding the development of highly palatable solid foods with enhanced satiating capacities.

    Mature male Pacific salmon (Genus Oncorhynchus) develop a dorsal hump, as a secondary male sexual characteristic, during the spawning period. Previous gross anatomical studies have indicated that the dorsal humps of salmon are mainly composed of cartilaginous tissue (Davidson [1935] J Morphol 57:169-183.) However, the histological and biochemical characteristics of such humps are poorly understood. In this study, the detailed microstructures and components of the dorsal humps of pink salmon were analyzed using histochemical techniques and electrophoresis. In mature males, free interneural spines and neural spines were located in a line near to the median septum of the dorsal hump. No cartilaginous tissue was detected within the dorsal hump. Fibrous and mucous connective tissues were mainly found in three regions of the dorsal hump: i) the median septum, ii) the distal region, and iii) the crescent-shaped region. Both the median septum and distal region consisted of connective tissue with a high water content, which contained elastic fibers and hyaluronic acid. It was also demonstrated that the lipid content of the dorsal hump connective tissue was markedly decreased in the mature males compared with the immature and maturing males. Although, the crescent-shaped region of the hump consisted of connective tissue, it did not contain elastic fibers, hyaluronic acid, or lipids. In an ultrastructural examination, it was found that all of the connective tissues in the dorsal hump were composed of collagen fibers. Gel electrophoresis of collagen extracts from these tissues found that the collagen in the dorsal hump is composed of Type I collagen, as is the case in salmon skin. These results indicate that in male pink salmon the dorsal hump is formed as a result of an increase in the amount of connective tissue, rather than cartilage, and the growth of free interneural spines and neural spines.

    To date, knowledge of the immune system in aquatic invertebrates has been reported in only a few model organisms, even though all metazoans have an innate immune system. In particular, information on the copepod's immunity and the potential role of key genes in the innate immune systems is still unclear. In this study, we identified dorsal and dorsal-like genes in the cyclopoid copepod Paracyclopina nana. In silico analyses for identifying conserved domains and phylogenetic relationships supported their gene annotations. The transcriptional levels of both genes were slightly increased from the nauplius to copepodid stages, suggesting that these genes are putatively involved in copepodid development of P. nana. To examine the involvement of both genes in the innate immune response and under stressful conditions, the copepods were exposed to lipopolysaccharide (LPS), different culture densities, salinities, and temperatures. LPS significantly upregulated mRNA expressions of dorsal and dorsal-like genes, suggesting that both genes are transcriptionally sensitive in response to immune modulators. Exposure to unfavorable culture conditions also increased mRNA levels of dorsal and dorsal-like genes. These findings suggest that transcriptional regulation of the dorsal and dorsal-like genes would be associated with environmental changes in P. nana.

  16. The sensory dorsal organs of crustaceans.

    2013-05-01

    The cuticle of crustaceans bears numerous organs, of which the functions of many are unknown. One of these, the sensory dorsal organ (SDO), is present in a wide diversity of taxa. Here we critically review the variability, ultrastructure, distribution, and possible function of this enigmatic cuticular organ. Previous data are complemented by new observations on larvae and adults of various malacostracans. The SDO is composed of four sensors arranged as the corners of a square, the centre of which is occupied by a gland. Pores or pegs surrounding this central complex may also form part of the organ. The arrangement and the external aspect of the five main elements varies greatly, but this apparently has little impact on their ultrastructural organisation. The sensors and the gland are associated with a particularly thin cuticle. Each sensor contains four outer dendritic segments and the central gland is made of a single large cell. It is not yet known what this large cell secretes. The SDO is innervated from the tritocerebrum and therefore belongs to the third cephalic segment. A similar organ, here called the posterior SDO, has been repeatedly observed more posteriorly on the carapace. It resembles the SDO but has a greater number of sensors (usually six, but up to ten) apparently associated with only two outer dendritic segments. The SDO and the posterior SDO are known in the Eumalacostraca, the Hoplocarida, and the Phyllocarida. Some branchiopods also possess a 'dorsal organ' resembling both the SDO and the ion-transporting organ more typical of this group. This may indicate a common origin for these two functionally distinct groups of organs. New observations on the posterior SDO support the hypothesis that the SDO and the posterior SDO are homologous to the lattice organ complexes of the costracans. However, the relationship between the SDO and the dorsal cephalic hump of calanoid copepods remains unclear. No correlation can be demonstrated between the presence

    Full Text Available Se conoce que el cuidado de los pies, uno de los mayores retos en la atención a personas diabéticas, no se enfoca adecuadamente en las consultas de rutina por lo cual se pierde la función preventiva de las complicaciones en miembros inferiores y su máxima manifestación: la amputación. Para lograr un acercamiento a este problema el trabajo tuvo como objetivo determinar la información y las orientaciones prácticas que tenía un grupo de pacientes diabéticos que sufrían una amputación en el momento del estudio. Se entrevistaron 105 diabéticos hospitalizados en las salas de Angiología de 2 hospitales generales. La entrevista se dirigió a recoger información que permitiera caracterizar el actual proceso de amputación y determinar la información y las orientaciones prácticas que sobre el cuidado de los pies en general y su proceso particular de amputación, habían recibido estas personas. Se encontró que el 62,5 % del grupo no revisaba periódicamente sus pies y el 42,4 % no identificó como peligrosas algunas prácticas caseras ante callosidades, cortado de uñas, etc. Solamente el 29,5 % pudo identificar 1 ó 2 cuidados prácticos de los pies. Se comprobó que no habían recibido información práctica al respecto y que en el 52,4 %, el inicio de la presente complicación fue por descuido, errores de conducta o ignorancia de cómo proceder.

    1979-07-01

    Findings of the environmental impact evaluation of the PIES TRENDLONG MID-MID Scenario for Federal Region VII (Iowa, Kansas, Nebraska, and Missouri) are reported. Projected coal-fired utility expansion could be constrained in several areas because of projected TSP and SO/sub 2/ National Ambient Air Quality Standards (NAAQS) violations. Problems will be most pronounced in Iowa and Kansas, but could be incurred in any state in the region. Large coal and nuclear facilities projected for parts of Region VII may experience water availability problems. The Smokey Hill River in Kansas, the Skunk River in Iowa, and the Platte River in Nebraska may have limited water supplies for operating the projected increases in fossil fuel and nuclear generating facilities. Coal surface mining in Missouri (21,000 acres may be disturbed from 1975 to 1990) may create land-use conflicts. Region VII may not have the facilities or legal framework for mitigating the negative socioeconomic impacts that are projected to occur from the proposed energy development. Therefore, the potential for severe and pervasive socioeconomic impacts is great.

    Owing to the overwhelming advantage in energy density, lithium-sulfur (Li-S) battery is a promising next-generation electrochemical energy storage system. Despite many efforts in pursuing long cycle life, relatively little emphasis has been placed on increasing the areal energy density. Herein, we have designed and developed a `pie' structured electrode, which provides an excellent balance between gravimetric and areal energy densities. Combining lotus root-like multichannel carbon nanofibers `filling' and amino-functionalized graphene `crust', the free-standing paper electrode (S mass loading: 3.6 mg cm-2) delivers high specific capacity of 1,314 mAh g-1 (4.7 mAh cm-2) at 0.1 C (0.6 mA cm-2) accompanied with good cycling stability. Moreover, the areal capacity can be further boosted to more than 8 mAh cm-2 by stacking three layers of paper electrodes with S mass loading of 10.8 mg cm-2.

    This study examines the dynamic co-localization of lipid-anchored fluorescent proteins in living cells using pulsed-interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS) and fluorescence lifetime analysis. Specifically, we look at the pairwise co-localization of anchors from lymphocyte cell kinase (LCK: myristoyl, palmitoyl, palmitoyl), RhoA (geranylgeranyl), and K-Ras (farnesyl) proteins in different cell types. In Jurkat cells, a density-dependent increase in cross-correlation among RhoA anchors is observed, while LCK anchors exhibit a more moderate increase and broader distribution. No correlation was detected among K-Ras anchors or between any of the different anchor types studied. Fluorescence lifetime data reveal no significant Förster resonance energy transfer in any of the data. In COS 7 cells, minimal correlation was detected among LCK or RhoA anchors. Taken together, these observations suggest that some lipid anchors take part in anchor-specific co-clustering with other existing clusters of native proteins and lipids in the membrane. Importantly, these observations do not support a simple interpretation of lipid anchor-mediated organization driven by partitioning based on binary lipid phase separation.

    This research used a collaborative approach to gain a comprehensive, quantitative understanding of the breadth and depth of the social work role in health care. Data was collected from individual interviews with all employed hospital social workers (N = 120) across five Melbourne, Australia health networks about their most recently completed case. This data was coded using a revised version of the Karls and Wandrei (1994) Person-in-Environment (PIE) tool to retrospectively analyze the reasons for social work involvement over the course of the case. The findings demonstrate that the hospital social work role is multidimensional across a number of domains but centers predominantly on assisting clients and their significant others with issues of altered social roles and functioning; particularly in relation to role responsibility, dependency, and managing associated role-change losses. The findings of this study will assist hospital social workers, managers, and academics to better describe and effectively undertake this complex work. These findings will also assist in the development of professional training and education to up-skill social workers who operate within this complex setting.

    The hypothesis of this work is that, in order to escape the natural immune surveillance mechanisms, cancer cells and the surrounding microenvironment might express ectopically genes that are physiologically present in the placenta to mediate fetal immune-tolerance. These natural “placental immune-editing switch” mechanisms (PIES) may represent the result of millions of years of mammalian evolution developed to allow materno-fetal tolerance. Here, we introduce genes of the immune regulatory pathways that are either similarly over- or under-expressed in tumor vs normal tissue. Our analysis was carried out in primary breast cancer with metastatic homolateral axillary lymph nodes as well as placenta tissue (both uterine decidual tissue and term placenta tissue) from a pregnant woman. Gene expression profiling of paired non-self and self tissues (i.e. placenta/uterus; breast cancer/normal breast tissue; metastatic lymphnode/normal lymphnode tissue) was performed using the PanCancer Immune gene panel, a 770 Nanostring gene expression panel. Our findings reveal overlapping in specific immune gene expression in placenta and cancer tissue, suggesting that these genes might play an important role in maintaining immune tolerance both physiologically (in the placenta) and pathologically (in the cancer setting).

    Music maintains a characteristic balance between repetition and novelty. Here, we report a similar balance in singing performances of free-living Australian pied butcherbirds. Their songs include many phrase types. The more phrase types in a bird's repertoire, the more diverse the singing performance can be. However, without sufficient temporal organization, avian listeners may find diverse singing performances difficult to perceive and memorize. We tested for a correlation between the complexity of song repertoire and the temporal regularity of singing performance. We found that different phrase types often share motifs (notes or stereotyped groups of notes). These shared motifs reappeared in strikingly regular temporal intervals across different phrase types, over hundreds of phrases produced without interruption by each bird. We developed a statistical estimate to quantify the degree to which phrase transition structure is optimized for maximizing the regularity of shared motifs. We found that transition probabilities between phrase types tend to maximize regularity in the repetition of shared motifs, but only in birds of high repertoire complexity. Conversely, in birds of low repertoire complexity, shared motifs were produced with less regularity. The strong correlation between repertoire complexity and motif regularity suggests that birds possess a mechanism that regulates the temporal placement of shared motifs in a manner that takes repertoire complexity into account. We discuss alternative musical, mechanistic and ecological explanations to this effect. PMID:27703699

    2006-01-01

    Juvenile idiopathic osteoporosis (JIO) is a rare condition of unknown aetiology, with pre-pubertal onset and frequently spontaneous remission after puberty. We report a case of a 14 years old boy, which two years before began dorso-lumbar pain with dorsal kyphosis. At the age of 12, he was on percentil 25 for height and had no other symptoms or alterations on physical exam. He had multiple vertebral fractures, a low serum vitamin D, and a Z-score in lumbar spine of -5,3. Diagnosis of JIO was made after excluding other causes of juvenile osteoporosis. He was submitted to pamidronate therapy and after six months showed clinical and bone mineral density improvement. At the age of 14 he is asymptomatic. The authors present this clinical case because of is rarity and to point out that although many cases have spontaneous remission, without any therapy, some may persist and become more serious, with pain and multiple fractures, justifying therapeutic intervention.

    Full Text Available Introducción: si bien el crecimiento prenatal y posnatal del pie ha sido documentado hace varios años, el crecimiento longitudinal del primer metatarsiano en particular no ha sido estudiado previamente. El objetivo del estudio es determinar el patrón de crecimiento longitudinal posnatal de este hueso y compararlo con el del pie y los huesos largos del miembro inferior. Materiales y Métodos: mediante una búsqueda informatizada, se identificaron pacientes <18 años de edad con radiografías informadas como “normal” por el radiólogo. Se analizó una muestra de 886 pacientes divididos en 18 grupos según la edad (0-11 meses, 1 año, 2 años, etc. y el sexo. El análisis de las imágenes se realizó con un software de imágenes Kodak Carestream PACS. Resultados: el largo promedio en el primer grupo fue de 19,91 mm (3,20; 15,22-25,62. El largo promedio en el último grupo fue de 66,13 mm (5,33; 52,50-77,18. La tasa de crecimiento anual fue de 2,71 mm. La edad promedio al momento del cierre de la fisis fue de 14.85 años (± 1.64 para los varones y 14.77 años (± 3.63 para las niñas. Conclusión: el crecimiento del primer metatarsiano acompaña el crecimiento longitudinal del pie, pero no el de los huesos largos del miembro inferior. Las curvas de crecimiento del primer metatarsiano descritas en este artículo pueden ser aplicadas en patologías que afectan el desarrollo del pie o que requieren cirugía de corrección sobre el primer metatarsiano, o se las puede emplear como estándar de referencia en futuros estudios.

  15. 'What' Is Happening in the Dorsal Visual Pathway.

    Freud, Erez; Plaut, David C; Behrmann, Marlene

    2016-10-01

    The cortical visual system is almost universally thought to be segregated into two anatomically and functionally distinct pathways: a ventral occipitotemporal pathway that subserves object perception, and a dorsal occipitoparietal pathway that subserves object localization and visually guided action. Accumulating evidence from both human and non-human primate studies, however, challenges this binary distinction and suggests that regions in the dorsal pathway contain object representations that are independent of those in ventral cortex and that play a functional role in object perception. We review here the evidence implicating dorsal object representations, and we propose an account of the anatomical organization, functional contributions, and origins of these representations in the service of perception.

  16. Involvement of dorsal root ganglia in Fabry's disease.

    Bouts of shooting pain along the extremities are common in the early stages of Fabry's disease. No pathological explanation has been advanced to clarify the mechanism of such pain. In the present case neuronal storage of glycolipid was confined to dorsal root ganglia neurones only. It is suggested that this may explain the shooting pain in Fabry's disease. In hereditary sensory radicular neuropathy, familial dysautonomia, and tabes dorsalis, changes in dorsal root ganglia cells cause similar clinical signs and thus it may be concluded that shooting pains in Fabry's disease may be caused by damage to dorsal root ganglia neurones.

    Sensory information is conveyed to the central nervous system by primary afferent neurons within dorsal root ganglia (DRG), which synapse onto neurons of the dorsal horn of the spinal cord. This synaptic connection is central to the processing of both sensory and pain stimuli. Here, we describe a model system to monitor synaptic transmission between DRG neurons and dorsal horn neurons that is compatible with high-throughput screening. This co-culture preparation comprises DRG and dorsal horn neurons and utilizes Ca(2+) imaging with the indicator dye Fura-2 to visualize synaptic transmission. Addition of capsaicin to co-cultures stimulated DRG neurons and led to activation of dorsal horn neurons as well as increased intracellular Ca(2+) concentrations. This effect was dose-dependent and absent when DRG neurons were omitted from the culture. NMDA receptors are a critical component of synapses between DRG and dorsal horn neurons as MK-801, a use-dependent non-competitive antagonist, prevented activation of dorsal horn neurons following capsaicin treatment. This model system allows for rapid and efficient analysis of noxious stimulus-evoked Ca(2+) signal transmission and provides a new approach both for investigating synaptic transmission in the spinal cord and for screening potential analgesic compounds.

  18. SPINAL DEFORMITIES AFTER SELECTIVE DORSAL RHIZOTOMY

    Directory of Open Access Journals (Sweden)

    PATRICIO PABLO MANZONE

    Full Text Available ABSTRACT Objective: Selective dorsal rhizotomy (SDR used for spasticity treatment could worsen or develop spinal deformities. Our goal is to describe spinal deformities seen in patients with cerebral palsy (CP after being treated by SDR. Methods: Retrospective study of patients operated on (SDR between January/1999 and June/2012. Inclusion criteria: spinal Rx before SDR surgery, spinography, and assessment at follow-up. We evaluated several factors emphasizing level and type of SDR approach, spinal deformity and its treatment, final Risser, and follow-up duration. Results: We found 7 patients (6 males: mean age at SDR 7.56 years (4.08-11.16. Mean follow-up: 6.64 years (2.16-13, final age: 14.32 years (7.5-19. No patient had previous deformity. GMFCS: 2 patients level IV, 2 level III, 3 level II. Initial walking status: 2 community walkers, 2 household walkers, 2 functional walkers, 1 not ambulant, at the follow-up, 3 patients improved, and 4 kept their status. We found 4 TL/L laminotomies, 2 L/LS laminectomies, and 1 thoracic laminectomy. Six spinal deformities were observed: 2 sagittal, 3 mixed, and 1 scoliosis. There was no association among the type of deformity, final gait status, topographic type, GMFCS, age, or SDR approach. Three patients had surgery indication for spinal deformity at skeletal maturity, while those patients with smaller deformities were still immature (Risser 0 to 2/3 although with progressive curves. Conclusions: After SDR, patients should be periodically evaluated until they reach Risser 5. The development of a deformity does not compromise functional results but adds morbidity because it may require surgical treatment.

  19. Environmental evaluation of the PIES Trendlong Mid-Mid Scenario: Federal Region V

    Energy Technology Data Exchange (ETDEWEB)

    1979-07-01

    This Regional Issues Identification and Assessment (RIIA), is an evaluation of the regional environmental impacts of future energy development. The impacts described for 1985 and 1990 are based on a national energy projection (scenario) that assumes medium energy demand and fuel supply through 1990 but does not incorporate the policies of the 1978 National Energy Act (NEA). The environmental impacts discussed in this volume are for Federal Region V. There are nine companion volumes, one for each of the other federal regions in the nation. The findings of this impact evaluation of the PIES TRENDLONG MID-MID Scenario for Federal Region V (Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin) are reported. In those areas of eastern Michigan and southeastern and central Wisconsin that have not attained National Ambient Air Quality Standards (NAAQS), there will be limited opportunities for mitigation of impacts from utility coal growth through emission offsets or improved control efficiencies. In Ohio, 30% of utility coal growth could be restricted primarily because of NAAQS nonattainment. Illinois, Indiana, and Ohio may also experience problems with oil-fired utilities in nonattainment areas, but fuel purchasinhg practices could reduce the air quality impacts. Utility and industrial siting along Lake Erie may require extensive pretreatment of effluents discharged into the Lake. Allocation of water from Lake Michigan for new facilities may become an issue in Wisconsin and Illinois where large water-for-energy demands conflict with other water uses. Surface mining activities in Illinois, Indiana, and Ohio are projected to disturb approximately 200,000 acres in the period 1975 to 1990, causing temporary or permanent shifts in productivity and land use. Much of the land in the mining area is presently in forest and crops. Deaths and illnesses resulting from employment in deep mining in Region V may increase 30 to 40% over 1975 levels.

    The LOCA experiment on the second rod (IFA-650.2) a fresh, low-tin Zr-4, pressurised PWR rod was carried out in May 2004. The main objective was to produce ballooning, to determine the time to burst and to assess the material oxidation and hydriding kinetics. The rod pressure at hot conditions and peak PCT were 70 bar and 1050 C, respectively. To document the effect of the LOCA testing on the cladding, rod 2 was subjected in PIE to visual inspection, profilometry and metallography. On visual inspection the clad shows a typical balloon. In the region of max ballooning the clad shows a 35 mm long, < 20 mm burst opening. In the balloon region the outer clad diameter increased by <35% and locally the wall thickness reduction is >55%. The entire rod is covered with a black oxide layer. Below and above the split opening the continuous oxide layer was 40 to 50mum both on water and fuel side of the clad. At the locations of the upper and lower cladding thermocouples the oxide thickness was in the range 24-27 mum. Widmanstaetten structure is seen in the bulk of the clad and confirms the high temperature experienced. A some 40mum wide, hard and brittle zone with oxygen rich globular alpha-grains is found both at the outer and the inner edge of the clad in the balloon region. The zone is widest near the axial split (crack). In the clad few, arbitrary oriented hydride platelets are observed in the balloon area. (Author)

  1. Meaningful call combinations and compositional processing in the southern pied babbler

    Engesser, Sabrina; Ridley, Amanda R.; Townsend, Simon W.

    2016-01-01

    Language’s expressive power is largely attributable to its compositionality: meaningful words are combined into larger/higher-order structures with derived meaning. Despite its importance, little is known regarding the evolutionary origins and emergence of this syntactic ability. Although previous research has shown a rudimentary capability to combine meaningful calls in primates, because of a scarcity of comparative data, it is unclear to what extent analog forms might also exist outside of primates. Here, we address this ambiguity and provide evidence for rudimentary compositionality in the discrete vocal system of a social passerine, the pied babbler (Turdoides bicolor). Natural observations and predator presentations revealed that babblers produce acoustically distinct alert calls in response to close, low-urgency threats and recruitment calls when recruiting group members during locomotion. On encountering terrestrial predators, both vocalizations are combined into a “mobbing sequence,” potentially to recruit group members in a dangerous situation. To investigate whether babblers process the sequence in a compositional way, we conducted systematic experiments, playing back the individual calls in isolation as well as naturally occurring and artificial sequences. Babblers reacted most strongly to mobbing sequence playbacks, showing a greater attentiveness and a quicker approach to the loudspeaker, compared with individual calls or control sequences. We conclude that the sequence constitutes a compositional structure, communicating information on both the context and the requested action. Our work supports previous research suggesting combinatoriality as a viable mechanism to increase communicative output and indicates that the ability to combine and process meaningful vocal structures, a basic syntax, may be more widespread than previously thought.

    Full Text Available The dorsal striatum (caudate/putamen is a node of the cortico-striato-pallido-thalamo-cortical (CSPTC motor circuit, which plays a central role in skilled motor learning, a critical feature of musical performance. The dorsal striatum receives input from a large part of the cerebral cortex, forming a hub in the cortical-subcortical network. This study sought to examine how the functional network of the dorsal striatum differs between musicians and nonmusicians.Resting state functional magnetic resonance imaging (fMRI data were acquired from female university students majoring in music and nonmusic disciplines. The data were subjected to graph theoretical analysis and functional connectivity analysis. The graph theoretical analysis of the entire brain revealed that the degree, which represents the number of connections, of the bilateral putamen was significantly lower in musicians than in nonmusicians. The functional connectivity analysis indicated that compared with nonmusicians, musicians had significantly decreased connectivity between the left putamen and bilateral frontal operculum and between the left caudate nucleus and cerebellum. In conclusion, compared with nonmusicians, female musicians have a smaller functional network of the dorsal striatum, with decreased connectivity. These data are consistent with previous anatomical studies reporting a reduced volume of the dorsal striatum in musicians and ballet dancers. To the best of our knowledge, this is the first study suggesting that long-term musical training results in a less extensive or selective functional network of the dorsal striatum.

  4. A bipartite U1 site represses U1A expression by synergizing with PIE to inhibit nuclear polyadenylation.

    U1A protein negatively autoregulates itself by polyadenylation inhibition of its own pre-mRNA by binding as two molecules to a 3'UTR-located Polyadenylation Inhibitory Element (PIE). The (U1A)2-PIE complex specifically blocks U1A mRNA biosynthesis by inhibiting polyA tail addition, leading to lower mRNA levels. U1 snRNP bound to a 5'ss-like sequence, which we call a U1 site, in the 3'UTRs of certain papillomaviruses leads to inhibition of viral late gene expression via a similar mechanism. Although such U1 sites can also be artificially used to potently silence reporter and endogenous genes, no naturally occurring U1 sites have been found in eukaryotic genes. Here we identify a conserved U1 site in the human U1A gene that is, unexpectedly, within a bipartite element where the other part represses the U1 site via a base-pairing mechanism. The bipartite element inhibits U1A expression via a synergistic action with the nearby PIE. Unexpectedly, synergy is not based on stabilizing binding of the inhibitory factors to the 3'UTR, but rather is a property of the larger ternary complex. Inhibition targets the biosynthetic step of polyA tail addition rather than altering mRNA stability. This is the first example of a functional U1 site in a cellular gene and of a single gene containing two dissimilar elements that inhibit nuclear polyadenylation. Parallels with other examples where U1 snRNP inhibits expression are discussed. We expect that other cellular genes will harbor functional U1 sites.

    A comparison is made of results from the PIES code, which determines the equilibrium properties of three-dimensional toroidal configurations by direct integration along the magnetic field lines, with those from the VMEC code, which uses an energy minimization in a flux representation to determine the equilibrium configuration, for two devices: the ATF stellarator at Oak Ridge and the TJ-11 heliac which is being built in Madrid. The results obtained from the two codes are in good agreement, providing additional validation for the codes.

  10. Endomorphins: localization, release and action on rat dorsal horn neurons.

    Science.gov (United States)

    2000-01-01

    Endomorphin (Endo) 1 and 2, two tetrapeptides isolated from the bovine and human brain, have been proposed to be the endogenous ligand for the mu-opiate receptor. A multi-disciplinary study was undertaken to address the issues of localization, release and biological action of Endo with respect to the rat dorsal horn. First, immunohistochemical studies showed that Endo-1- or Endo-2-like immunoreactivity (Endo-1- or Endo-2-LI) is selectively expressed in fiber-like elements occupying the superficial layers of the rat dorsal horn, which also exhibit a high level of mu-opiate receptor immunoreactivity. Second, release of immunoreactive Endo-2-like substances (irEndo) from the in vitro rat spinal cords upon electrical stimulation of dorsal root afferent fibers was detected by the immobilized antibody microprobe technique. The site of release corresponded to laminae I and II where the highest density of Endo-2-LI fibers was localized. Lastly, whole-cell patch clamp recordings from substantia gelatinosa (SG) neurons of rat lumbar spinal cord slices revealed two distinct actions of exogenous Endo-1 and Endo-2: (1) depression of excitatory and/or inhibitory postsynaptic potentials evoked by stimulation of dorsal root entry zone, and (2) hyperpolarization of SG neurons. These two effects were prevented by the selective mu-opiate receptor antagonist beta-funaltrexamine. The localization of endomorphin-positive fibers in superficial layers of the dorsal horn and the release of irEndo upon stimulation of dorsal root afferents together with the observation that Endo inhibits the activity of SG neurons by interacting with mu-opiate receptors provide additional support of a role of Endo as the endogenous ligand for the mu-opiate receptor in the rat dorsal horn.

    The technology of "pied de cuve" (PdC) is applied in food process only to produce wines with an enriched community of pro-technological yeasts. PdC promotes the growth of the desirable microbial strains in a small volume of grape must acting as a starter inoculums for higher volumes. The aim of the present work was to investigate the use of partially fermented brines, a technology known as PdC, developed with lactic acid bacteria (LAB) on the microbiological, chemical and sensory characteristics of green fermented table olives during two consecutive campaigns. The experimental plan included two trials based on different PdCs: trial A, PdC obtained with Lactobacillus pentosus OM13; trial B, PdC obtained through a spontaneous fermentation. Two control additional trials without PdC were included for comparison: trial C, spontaneous fermentation; trial D, direct inoculation of L. pentosus OM13. The use of PdCs favoured the rapid increase of LAB concentrations in both trials A and B. These trials showed levels of LAB higher than trial C and almost superimposable to that of trial D. Trial B was characterized by a certain diversity of L. pentosus strains and some of them dominated the manufacturing process. These results indicated PdC as a valuable method to favour the growth of autochthonous L. pentosus strains. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) visibly discriminated olive processes fermented with the two experimental PdCs. Interestingly, on the basis of microbial and pH variables, both approaches showed that the olives produced with PdC technology are closely related to those of trial D, with the advantages of reducing the amount of starter to inoculate (trial A) and a higher LAB biodiversity (trial B). Volatile organic compound (VOC) composition and sensory analysis showed trials A and B different from the trials with no PdC added, in both years. Furthermore, the trial B showed the highest scores of green olive aroma and

  12. Vortex wake, downwash distribution, aerodynamic performance and wingbeat kinematics in slow-flying pied flycatchers.

    Many small passerines regularly fly slowly when catching prey, flying in cluttered environments or landing on a perch or nest. While flying slowly, passerines generate most of the flight forces during the downstroke, and have a 'feathered upstroke' during which they make their wing inactive by retracting it close to the body and by spreading the primary wing feathers. How this flight mode relates aerodynamically to the cruising flight and so-called 'normal hovering' as used in hummingbirds is not yet known. Here, we present time-resolved fluid dynamics data in combination with wingbeat kinematics data for three pied flycatchers flying across a range of speeds from near hovering to their calculated minimum power speed. Flycatchers are adapted to low speed flight, which they habitually use when catching insects on the wing. From the wake dynamics data, we constructed average wingbeat wakes and determined the time-resolved flight forces, the time-resolved downwash distributions and the resulting lift-to-drag ratios, span efficiencies and flap efficiencies. During the downstroke, slow-flying flycatchers generate a single-vortex loop wake, which is much more similar to that generated by birds at cruising flight speeds than it is to the double loop vortex wake in hovering hummingbirds. This wake structure results in a relatively high downwash behind the body, which can be explained by the relatively active tail in flycatchers. As a result of this, slow-flying flycatchers have a span efficiency which is similar to that of the birds in cruising flight and which can be assumed to be higher than in hovering hummingbirds. During the upstroke, the wings of slowly flying flycatchers generated no significant forces, but the body-tail configuration added 23 per cent to weight support. This is strikingly similar to the 25 per cent weight support generated by the wing upstroke in hovering hummingbirds. Thus, for slow-flying passerines, the upstroke cannot be regarded as inactive

    The sites of action and cellular mechanisms by which spinal cord stimulation reduces neuropathic pain remain unclear. We examined the effect of bipolar electrical-conditioning stimulation (50 Hz, 0.2 ms, 5 min) of the dorsal column and lumbar dorsal roots on the response properties of spinal wide dynamic range (WDR) neurons in rats after L5 spinal nerve injury. The conditioning stimulation intensity was set at the lowest current that evoked a peak antidromic sciatic Aα/β-compound action potential without inducing an Aδ- or C-compound action potential. Within 15 min of the dorsal column or root conditioning stimulation, the spontaneous activity rate of WDR neurons was significantly reduced in nerve-injured rats. Conditioning stimulation also significantly attenuated WDR neuronal responses to mechanical stimuli in nerve-injured rats and inhibited the C-component of the neuronal response to graded intracutaneous electrical stimuli applied to the receptive field in nerve-injured and sham-operated rats. It is noteworthy that dorsal column stimulation blocked windup of WDR neuronal response to repetitive intracutaneous electrical stimulation (0.5 Hz) in nerve-injured and sham-operated rats, whereas dorsal root stimulation inhibited windup only in sham-operated rats. Therefore, stimulation of putative spinal substrates at A-fiber intensities with parameters similar to those used by patients with spinal cord stimulators attenuated established WDR neuronal hyperexcitability in the neuropathic condition and counteracted activity-dependent increase in neuronal excitability (i.e., windup). These results suggest a potential cellular mechanism underlying spinal cord stimulation-induced pain relief. This in vivo model allows the neurophysiologic basis for spinal cord stimulation-induced analgesia to be studied.

    The preparation of yeast starter culture (Pied de Cuve) for producing sparkling wine with the traditional method is a key factor for manufacturing a good Prise de mousse. In this paper, the evolution of total yeast population, its viability during Pied de Cuve preparation, and the pressure profile during the 2nd fermentation in 2 different base wines made from Bombino bianco and Chardonnay grapes were investigated using 4 different commercial active dried yeasts. The study proves that despite the initial differences observed throughout the acclimatization phase, all the tested strains showed similar results on either the total population (from 8.2 × 10(7) cells/mL to 1.3 × 10(8) cells/mL) or cellular viability (from 70% to 84%). Independently from the base wine tested, the kinetic of sugar consumption was faster during the gradual acclimatization to the alcoholic medium (phase II) and slower during the preparation of starter culture in active growth phase (phase III). During both of these phases Saccharomyces cerevisiae bayanus Vitilevure DV10(®) (Station œnotechnique de Champagne) proved to have a higher sugar consumption rate than the other strains. During the Prise de mousse, S. cerevisiae bayanus Lalvin EC-1118(®) (Lallemand) reached the maximum pressure increase within time in both base wines.

    In order to define the future intensity and reliability of the on line radioactive beams for the SPIRAL project, an intense activity of research and development is being done around the target and the ion source problems. The main instrument for this purpose is the isotopic separator SIRa (Separateur d'Ions Radioactifs) installed in the D2 experimental cave at GANIL. One of the research axis is the production of multicharged radioactive condensable ions. In this aim, we have built a new compact ECR ion source, SHyPIE (Source Hybride pour la Production d'Ions Exotiques), whose original magnetic configuration is under patent since 1997. This new magnetic structure allows to place an internal production target very close to the plasma, while avoiding radiation damages of the sensitive permanent magnets. A series of on line experiments have been done, using SHyPIE with several internal target systems, and around thirty species of condensable and noble gases radioactive multicharged ion beams have been produced. The behaviour of the plasma in a close geometry with the production target has been studied. (authors)

    Extensive loss of elbow flexion compromises the performance of daily activities. We examined the clinical outcomes of patients with post-traumatic extension contracture of the elbow treated with open arthrolysis and pie-crusting release of the triceps tendon. We retrospectively reviewed the records of 7 patients (5 men and 2 women; mean age, 35 years) who underwent open arthrolysis via a combined lateral and medial approach with pie-crusting release of the triceps tendon for the treatment of post-traumatic elbow stiffness. All the patients had heterotopic ossification that restricted elbow motion and underwent removal of the ossified tissue and capsular release. The triceps tendon was gradually stretched by making multiple stab incisions on the tendon by using a No. 11 surgical blade. The range of motion of the elbow was recorded both preoperatively and at the final postoperative follow-up. Elbow function was assessed with the Mayo Elbow Performance Score. The patients were followed up for a mean of 24 months. After treatment, significant improvement was noted in the total arc of motion (from 44° to 116°, P contracture of the elbow.

    Full Text Available A seismic velocity analysis from teleseismic receiver functions recorded in the southwestern fank of the Sierra de Pie de Palo (Western Sierras Pampeanas, Argentina, is compared with seismic properties directly calculated from lithological composition. The seismological results show an upper layer located in the first 13 km depth. A deeper contrast in seismic velocities is found at a depth of 28 km; the petrological results indicate a composition compatible with observed greenschist and amphibolite facies mafic rocks up to this depth. The receiver function measurements at 13 km and 28 km depths could be interpreted as two potential décollement levels that might have favoring a mechanism to thicken the whole crust, which produces a receiver function Moho signal located at 47 km depth. In addition, the lower crust between 28 km and 47 km exhibits high seismic P-wave velocities and Vp/Vs ratio (> 1.80 that are representative of a densification consistent with upper amphibolite to granulite/ecoglite facies lithologies. Based on these results, the combined petrological and seismological analyses suggest the continuation of the same mafic-crust outcropping lithologies into the lower levels of the 47-km thickened crust, which could be part of the Pie de Palo Complex ophiolite belt or the Precordillera basement.

    The dorsal nucleus of the vagus nerve plays an integral part in the control of visceral function. The aim of the present study was to correlate structural and chemical changes in the developing nucleus with available data concerning functional maturation of human viscera and reflexes. The fetal development (ages 9 to 26 weeks) of the human dorsal nucleus of the vagus nerve has been examined with the aid of Nissl staining and immunocytochemistry for calbindin and tyrosine hydroxylase. By 13 weeks, the dorsal vagal nucleus emerges as a distinct structure with at least two subnuclei visible in Nissl stained preparations. By 15 weeks, three subnuclei (dorsal intermediate, centrointermediate and ventrointermediate) were clearly discernible at the open medulla level with caudal and caudointermediate subnuclei visible at the level of the area postrema. All subnuclei known to exist in the adult were visible by 21 weeks and cytoarchitectonic differentiation of the nucleus was largely completed by 25 weeks. The adult distribution pattern of calbindin and tyrosine hydroxylase immunoreactive neurons was also largely completed by 21 weeks, although morphological differentiation of labeled neurons continued until the last age examined (26 weeks). The structural development of the dorsal nucleus of the vagus nerve appears to occur in parallel with functional maturation of the cardiovascular and gastric movements, which the nucleus controls.

Estos resultados ponen de manifiesto evidencias de dos discontinuidades intracorticales a profundidades de 13 y 28 km aproximadamente y una discontinuidad más profunda cerca de 47 km de profundidad que correspondería al Moho. Los valores de contraste entre las velocidades de ondas P y S (Vp/Vs para estas discontinuidades son en general elevados. En particular, la región comprendida entre 13 y 28 km de profundidad muestra los valores más altos de Vp/Vs lo cual indicaría un mayor grado de fracturación o fallamiento para esta zona de la corteza. Los resultados indican una densificación de la corteza inferior.In this paper receiver function results beneath the seismic station Coronel Fontana (31,605°S and 68,238°W, in the western Sierras Pampeanas are shown. These results provide evidence for two intracrustal discontinuities at depths of 13 km and 28 km approximately and a deeper discontinuity near 47 km depth, which correlates with the Moho. Overall the ratio between the seismic velocities of P and S waves (Vp/Vs for these discontinuities are high. In particular, the region between 13 and 28 km depth shows the higher values of Vp/Vs, which is consistent with a higher degree of fracturing and faulting. The results also indicate a denser composition of the lower crust.

    Previous studies indicated that intracerebroventricular administration of nerve growth factor (NGF) leads to massive Schwann cell hyperplasia surrounding the medulla oblongata and spinal cord. This study was designed to characterize the proliferation of peripheral glial cells, that is, Schwann and satellite cells, in the trigeminal ganglia and dorsal root ganglia (DRG) of adult rats during two weeks of NGF infusion using bromodeoxyuridine (BrdU) to label dividing cells. The trigeminal ganglia as well as the cervical and lumbar DRG were analyzed. Along the entire neuraxis a small number of dividing cells were observed within these regions under physiological condition. NGF infusion has dramatically increased the generation of new cells in the neuronal soma and axonal compartments of sensory ganglia and along the dorsal root and the dorsal root entry zone. Quantification of BrdU positive cells within sensory ganglia revealed a 2.3- to 3-fold increase in glial cells compared to controls with a similar response to NGF for the different peripheral ganglia examined. Immunofluorescent labeling with S100β revealed that Schwann and satellite cells underwent mitosis after NGF administration. These data indicate that intracerebroventricular NGF infusion significantly induces gliogenesis in trigeminal ganglia and the spinal sensory ganglia and along the dorsal root entry zone as well as the dorsal root.

  8. Dorsal eye selector pannier (pnr) suppresses the eye fate to define dorsal margin of the Drosophila eye

    Axial patterning is crucial for organogenesis. During Drosophila eye development, dorso-ventral (DV) axis determination is the first lineage restriction event. The eye primordium begins with a default ventral fate, on which the dorsal eye fate is established by expression of the GATA-1 transcription factor pannier (pnr). Earlier, it was suggested that loss of pnr function induces enlargement in the dorsal eye due to ectopic equator formation. Interestingly, we found that in addition to regulating DV patterning, pnr suppresses the eye fate by downregulating the core retinal determination genes eyes absent (eya), sine oculis (so) and dacshund (dac) to define the dorsal eye margin. We found that pnr acts downstream of Ey and affect the retinal determination pathway by suppressing eya. Further analysis of the “eye suppression” function of pnr revealed that this function is likely mediated through suppression of the homeotic gene teashirt (tsh) and is independent of homothorax (hth), a negative regulator of eye. Pnr expression is restricted to the peripodial membrane on the dorsal eye margin, which gives rise to head structures around the eye, and pnr is not expressed in the eye disc proper that forms the retina. Thus, pnr has dual function, during early developmental stages pnr is involved in axial patterning whereas later it promotes the head specific fate. These studies will help in understanding the developmental regulation of boundary formation of the eye field on the dorsal eye margin. PMID:20691679

    To describe the course of the dorsal nerve of the clitoris (DNC) to better define its anatomy in the human adult and to help surgeons to avoid iatrogenic injury during surgical procedures. An extensive review of the current literature was done on Medline via PubMed by using the following keywords: "anatomie du clitoris", "anatomy of clitoris", "nerf dorsal du clitoris", "dorsal nerve of clitoris", "réparation clitoridienne", "transposition clitoridienne", "surgery of the clitoris", "clitoridoplasty". This review analyzed dissection, magnetic resonance imaging, 3-dimensional sectional anatomy reconstruction and immuno-histochemical studies. The DNC comes from the pudendal nerve. He travels from under the inferior pubis ramus to the posterosuperior edge of the clitoral crus. The DNC reappears under the pubic symphysis and enters the deep component of the suspensory ligament. He runs on the dorsal face of the clitoral body at 11 and 1 o'clock. Distally, he gives many nervous ramifications, runs along the tunica and enters the glans. The NDC might be surgically injured (i) under the pubic symphysis, at the union of the two crus of clitoris and (ii) on the dorsal surface of the clitoral body. The pathway of the DNC on the dorsal face of the clitoris permits to approach the ventral face of the clitoris without risk of iatrogenic injuries. The distance between the pubic symphysis and the DNC implies that the incision should be done just under the pubic symphysis. Distally, the dissection of the DNC next the glands appears as dangerous and impossible, considering that the DNC is too close to the glandular tissues. Copyright © 2014 Elsevier Masson SAS.

    Full Text Available Background: The toe to hand transplantation is a method of reconstruction on the unique or multiple amputations of the fingers. It can be used the whole toe or with certain modifications as a wrap-around flap from the big toe or fingertip. It is a widely accepted option for the thumb.Methods: It is  a series of patients with amputation of one or more fingers of the hand were operated with second toe to hand transplantation. The survival was evaluated and the sensory recovery by 2-point discrimination.Results: We practiced 12 transplants, 8 thumb, and 4 in other fingers. Ten were adults and 2 children. All transplants survived. Two patients required tenolysis flexor. The sensibility was recovered with good 2-point discrimination of 8 mm.Discussion: In the more proximal finger amputations, a second toe is the most appropriate, with lower morbidity of the donor site. The rates of success are  between 95 to 100%. We had a success rate of 100%. The resulting defect is in the foot is minimum when the second toe was used. The decision to use one of these techniques depends on the decision and transplant surgeon training. We always used the second toe for transfers to the hand, considering that it will be thinner than the original thumb; our patients had no complaint about the appearance.Conclusion: Toe-to-hand transplantation is a good technique, providing a very good aesthetic appearance and allowing the recovery of sensitivity. The defect that is created in the foot does not produce significant aesthetic and functional alterations 

  16. Attention modulates the dorsal striatum response to love stimuli.

    2014-02-01

    In previous functional magnetic resonance imaging (fMRI) studies concerning romantic love, several brain regions including the caudate and putamen have consistently been found to be more responsive to beloved-related than control stimuli. In those studies, infatuated individuals were typically instructed to passively view the stimuli or to think of the viewed person. In the current study, we examined how the instruction to attend to, or ignore the beloved modulates the response of these brain areas. Infatuated individuals performed an oddball task in which pictures of their beloved and friend served as targets and distractors. The dorsal striatum showed greater activation for the beloved than friend, but only when they were targets. The dorsal striatum actually tended to show less activation for the beloved than the friend when they were distractors. The longer the love and relationship duration, the smaller the response of the dorsal striatum to beloved-distractor stimuli was. We interpret our findings in terms of reinforcement learning. By virtue of using a cognitive task with a full factorial design, we show that the dorsal striatum is not activated by beloved-related information per se, but only by beloved-related information that is attended.

    Muscle architecture is considered to reflect the function of muscle in vivo, and is important for example to clinicians in designing tendon-transfer and tendon-lengthening surgeries. The purpose of this study was to quantify the architectural properties of the FDI muscle. It is hypothesized that there will be consistency, that is low variability, in the architectural parameters used to describe the first dorsal interosseous muscle because of its clear functional role in index finger motion. The important architectural parameters identified were those required to characterize a muscle adequately by modeling. Specifically the mass, cross-sectional area, and length of the tendon and muscle were measured in cadavers along with the muscle fiber optimum length and pennation angle, and the moment arm of the first dorsal interosseous at the metacarpophalangeal joint. These parameters provide a characterization of the architecture of the first dorsal interosseous, and were used to indicate the inherent variability between samples. The results demonstrated a large amount of variability for all architectural parameters measured; leading to a rejection of the hypothesis. Ratios designed to describe the functioning of the muscles in vivo, for example the ratio of tendon to fiber optimum lengths, also demonstrated a large variability. The results suggest that function cannot be deduced from form for the first dorsal interosseous, and that subject-specific architectural parameters may be necessary for the formulation of accurate musculoskeletal models or making clinical decisions.

    Development of hepatocellular carcinoma (HCC) is a multi-factorial process. Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are important risk factors of HCC. Host factors, such as alcohol drinking, may also play a role. This study aims to provide a synthesis view on the development of HCC by examining multiple risk factors jointly and collectively. Causal-pie modeling technique was applied to analyze a cohort of 11,801 male residents (followed up for 15 years) in Taiwan, during which a total of 298 incident HCC cases were ascertained. The rate ratios adjusted by age were further modeled by an additive Poisson regression. Population attributable fractions (PAFs) and causal-pie weights (CPWs) were calculated. A PAF indicates the magnitude of case-load reduction under a particular intervention scenario, whereas a CPW for a particular class of causal pies represents the proportion of HCC cases attributable to that class. Using PAF we observed a chance to reduce around 60% HCC risk moving from no HBV-related intervention to the total elimination of the virus. An additional ∼15% (or ∼5%) reduction can be expected, if the HBV-related intervention is coupled with an HCV-related intervention (or an anti-drinking campaign). Eight classes of causal pies were found to be significant, including four dose-response classes of HBV (total CPW=52.7%), one independent-effect class of HCV (CPW=14.4%), one HBV-alcohol interaction class (CPW=4.2%), one HBV-HCV interaction class (CPW=1.7%), and one all-unknown class (CPW=27.0%). Causal-pie modeling for HCC helps clarify the relative importance of each viral and host factor, as well as their interactions.

    Full Text Available The aim of present study was to test hypothesis, that the leptin gene single nucleotide polymorphism (C/T giving missense mutation (Arg25Cys has an effect on concentration of blood serum total cholesterol, beta-hydroxybutyrate and urea in cattle. The experiment were performed in 58 Czech Pied bulls at 240 ± 9 days of age, which were divided in three experimental groups depending on different leptin genotypes (CC, n=28; CT, n=21; TT, n=9. Resulting genotypes in the exon 2 were CC (48.3%, CT (36.2%, and TT (15.5%. There were no differences in serum total cholesterol, urea, beta-hydroxybutyrate concentrations among the genotypes. Based on our results we may assume that analysed SNP of leptin gene have no effect on nutritional status and energy balance in fattened cattle.

    1993-12-01

    A nondestructive technique as well as a destructive PIE technique have been used to verify the results obtained with a newly 8-e computer tomography (GECT) system. Multi isotope Scanning (MIS), electron probe micro analysis (EPMA) and GECT were used on a mixed oxide (MOX) fuel rod from the Dodewaard reactor with an average burnup of 24 MWd/kg fuel. GECT shows migration of Cs to the periphery of fuel pellets and to radial cracks and pores in the fuel, whereas MIS shows Cs migration to pellet interfaces. The EPMA technique appeared not to be useful to show migration of Cs but, it shows the distribution of fission products from Pu. EPMA clearly shows the distribution of fission products from Pu, but did not reveal the Cs-migration. (orig./HP)

    2014-01-01

    The pathway that generates the dorsal-ventral (DV) axis of the Drosophila embryo has been the subject of intense investigation over the previous three decades. The initial asymmetric signal originates during oogenesis by the movement of the oocyte nucleus to an anterior corner of the oocyte, which establishes DV polarity within the follicle through signaling between Gurken, the Drosophila Transforming Growth Factor (TGF)-α homologue secreted from the oocyte, and the Drosophila Epidermal Growth Factor Receptor (EGFR) that is expressed by the follicular epithelium cells that envelop the oocyte. Follicle cells that are not exposed to Gurken follow a ventral fate and express Pipe, a sulfotransferase that enzymatically modifies components of the inner vitelline membrane layer of the eggshell, thereby transferring DV spatial information from the follicle to the egg. These ventrally sulfated eggshell proteins comprise a localized cue that directs the ventrally restricted formation of the active Spätzle ligand within the perivitelline space between the eggshell and the embryonic membrane. Spätzle activates Toll, a transmembrane receptor in the embryonic membrane. Transmission of the Toll signal into the embryo leads to the formation of a ventral-to-dorsal gradient of the transcription factor Dorsal within the nuclei of the syncytial blastoderm stage embryo. Dorsal controls the spatially specific expression of a large constellation of zygotic target genes, the Dorsal gene regulatory network, along the embryonic DV circumference. This article reviews classic studies and integrates them with the details of more recent work that has advanced our understanding of the complex pathway that establishes Drosophila embryo DV polarity.

  8. Induction of dorsal mesoderm by soluble, mature Vg1 protein.

    Kessler, D S; Melton, D A

    1995-07-01

    Mesoderm induction during Xenopus development has been extensively studied, and two members of the transforming growth factor-beta family, activin beta B and Vg1, have emerged as candidates for a natural inducer of dorsal mesoderm. Heretofore, analysis of Vg1 activity has relied on injection of hybrid Vg1 mRNAs, which have not been shown to direct efficient secretion of ligand and, therefore, the mechanism of mesoderm induction by processed Vg1 protein is unclear. This report describes injection of Xenopus oocytes with a chimeric activin-Vg1 mRNA, encoding the pro-region of activin beta B fused to the mature region of Vg1, resulting in the processing and secretion of mature Vg1. Treatment of animal pole explants with mature Vg1 protein resulted in differentiation of dorsal, but not ventral, mesodermal tissues and dose-dependent activation of both dorsal and ventrolateral mesodermal markers. At high doses, mature Vg1 induced formation of 'embryoids' with a rudimentary axial pattern, head structures including eyes and a functional neuromuscular system. Furthermore, truncated forms of the activin and FGF receptors, which block mesoderm induction in the intact embryo, fully inhibited mature Vg1 activity. To examine the mechanism of inhibition, we have performed receptor-binding assays with radiolabeled Vg1. Finally, follistatin, a specific inhibitor of activin beta B which is shown not to block endogenous dorsal mesoderm induction, failed to inhibit Vg1. The results support a role for endogenous Vg1 in dorsal mesoderm induction during Xenopus development.

    Background Depression is an important factor related to agitation and other behaviors in nursing home residents. As the next step in our Geriatric Education Center (GEC) Practice Improvement in Education (PIE) project on depression in nursing homes, we focused on non-pharmacologic behavioral management and psychoactive medication reduction. Methods This quality improvement (QI) pilot included training on effective interdisciplinary management approaches for depressive symptoms and challenging behaviors, and implementing an adapted ABC (antecedents, behaviors, consequences) log and behavioral activation. We targeted two nursing home floors and included data on residents present both before and after the QI, in June 2013 and July 2014. We examined changes in depressive symptom scores (Patient Health Questionnaire, or PHQ-9, scale 0-27, higher=worse) and antipsychotic/antidepressant medication use with paired T-tests and Fisher's exact tests. Results Of the 66 nursing home residents in this QI pilot, 70% were female, 60.6% were > 89 years old (range = 48–108, mean = 88.8), 83% were Asian and 51% had severe cognitive impairment. Mean PHQ-9 scores decreased significantly from 3.74 to 2.38 (P = .017). Of the 13/66 (19.7%) residents on antipsychotic medications, 10/13 (76.9%) had dose reductions and 4/13 (30.8%) had medications completely discontinued (P < .0001 for change pre/post). Of the 34 (51.5%) residents on antidepressant medication, 15/34 (42.9%) had dose reductions and 3/34 (8.8%) had medications completely discontinued (P < .0001 for change pre/post). Conclusion Mean depression scores and antipsychotic and antidepressant medication use decreased significantly in this GEC PIE QI project to manage depression and behaviors non-pharmacologically in nursing home residents.

  11. A new classification of the Pied Woodpeckers assemblage (Dendropicini, Picidae) based on a comprehensive multi-locus phylogeny.

    The pied woodpecker assemblage historically included the widespread genera Picoides and Dendrocopos. The assignment of species to either of these two genera has for long puzzled systematists due to their overall plumage similarity. Recent molecular studies not only suggested that both of these genera are not monophyletic, but also that four other genera, the African Dendropicos the South American Veniliornis and two Asian monospecific genera (Hypopicus and Sapheopipo) are nested within the Dendrocopos-Picoides clade. Yet, our current understanding of the phylogeny and taxonomy of this group is still very partial because several distinctive Old World species that have been assigned to different genera throughout their taxonomic history have not been sampled yet. Here, using DNA sequence data gathered from four loci, we reconstructed a species level phylogeny of the Indo-Malayan and Palearctic Pied Woodpeckers to understand the phylogenetic relationships and biogeographic history of the Eurasian species with respect to African and New World lineages. Our phylogenetic analyses revealed nine strongly supported clades within the Dendropicini. Noticeably, two species that had disputed affinities at the genus level clustered in clades with species from the same biogeographical region: the Brown-backed Woodpecker (D. obsoletus) is nested in Dendropicos and the Arabian Woodpecker (D. dorae) is related to two Eurasian species, the Brown-fronted (D. auriceps) and Middle-spotted woodpeckers (D. medius). The nine clades have a strong biogeographic component and very few dispersal event among bioregions occurred. For example, the African species formed a clade, suggesting that only one dispersal event is needed to explain the presence of Dendropicini in Africa. Based on our phylogenetic results, we propose a new classification of the Dendropicini that recognizes nine genera. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available En este trabajo se estudia la actividad sísmica en la sierra de Pie de Palo durante enero 2008 a diciembre 2009. Los datos utilizados fueron registrados por 52 estaciones sismológicas de los experimentos SIEMBRA y ESP. En ese período, 149 sismos corticales fueron localizados con magnitudes locales entre 0,8Pie de Palo con una ausencia en el sector centro occidental de la sierra y valle de Tulum. Además, se observa una distribución de sismos diferente para la corteza situada al norte con respecto al sur de la sierra: en el bloque norte, 52 hipocentros ocurrieron a niveles de corteza media a inferior mientras que en el boque sur, 73 sismos se concentraron principalmente en niveles corticales intermedios. Se observa una buena correlación de la sismicidad con el modelo de corteza local propuesto por Perarnau et al. (2010 posicionándose la mayor ocurrencia de actividad sísmica a profundidades de corteza media a inferior y ninguna determinación sísmica en el nivel más inferior sugiriendo un comportamiento probablemente más dúctil. Un total de 128 mecanismos focales fueron determinados utilizando primeros arribos de ondas P que indican soluciones principalmente de tipo inverso e inverso con componente de rumbo. Los resultados están de acuerdo con un acortamiento cortical en dirección aproximada este-oeste. Además, el estudio de las fuentes sísmicas realizado sugiere una deformación asociada diferente para los bloques que componen a la sierra, tanto en su extensión areal como en profundidad cortical.

    Full Text Available Dorsoventral patterning of the embryonic axis relies upon the mutual antagonism of competing signaling pathways to establish a balance between ventralizing BMP signaling and dorsal cell fate specification mediated by the organizer. In zebrafish, the initial embryo-wide domain of BMP signaling is refined into a morphogenetic gradient following activation dorsally of a maternal Wnt pathway. The accumulation of β-catenin in nuclei on the dorsal side of the embryo then leads to repression of BMP signaling dorsally and the induction of dorsal cell fates mediated by Nodal and FGF signaling. A separate Wnt pathway operates zygotically via Wnt8a to limit dorsal cell fate specification and maintain the expression of ventralizing genes in ventrolateral domains. We have isolated a recessive dorsalizing maternal-effect mutation disrupting the gene encoding Integrator Complex Subunit 6 (Ints6. Due to widespread de-repression of dorsal organizer genes, embryos from mutant mothers fail to maintain expression of BMP ligands, fail to fully express vox and ved, two mediators of Wnt8a, display delayed cell movements during gastrulation, and severe dorsalization. Consistent with radial dorsalization, affected embryos display multiple independent axial domains along with ectopic dorsal forerunner cells. Limiting Nodal signaling or restoring BMP signaling restores wild-type patterning to affected embryos. Our results are consistent with a novel role for Ints6 in restricting the vertebrate organizer to a dorsal domain in embryonic patterning.

    Wallace, Deanna L; Aarts, Esther; Dang, Linh C; Greer, Stephanie M; Jagust, William J; D'Esposito, Mark

    2014-01-01

    To date, few studies have explored the neurochemical mechanisms supporting individual differences in food preference in humans. Here we investigate how dorsal striatal dopamine, as measured by the positron emission tomography (PET) tracer [(18)F]fluorometatyrosine (FMT), correlates with food-related decision-making, as well as body mass index (BMI) in 16 healthy-weight to moderately obese individuals. We find that lower PET FMT dopamine synthesis binding potential correlates with higher BMI, greater preference for perceived "healthy" foods, but also greater healthiness ratings for food items. These findings further substantiate the role of dorsal striatal dopamine in food-related behaviors and shed light on the complexity of individual differences in food preference.

    The most frequently encountered complication of dorsal column stimulators is lead migration. The vast majority of these events are seen in the first few weeks to months. Late paddle lead migration is a very uncommon occurrence in this setting. We describe a case of a 51-year-old male with a history of reflex sympathetic dystrophy having undergone dorsal column stimulator insertion at the level of C1-C2. A good clinical benefit was appreciated in the postoperative period once the stimulator was turned on. Approximately six months postoperatively, the patient suddenly lost coverage. Radiographic imaging revealed that the lead had migrated caudally to the C3-C4 level. Subsequent revision surgery took place. This description highlights a common complication, but occurring outside the expected time frame after surgery.

  3. Principal Component Analysis of Thermal Dorsal Hand Vein Pattern Architecture

    Full Text Available The quest of providing more secure identification system has lead to rise in developing biometric systems. Biometrics such as face, fingerprint and iris have been developed extensively for human identification purpose and also to provide authentic input to many security systems in the past few decades. Dorsal hand vein pattern is an emerging biometric which is unique to every individual. In this study principal component analysis is used to obtain Eigen vein patterns which are low dimensional representation of vein pattern features. The extraction of the vein patterns was obtained by morphological techniques. Noise reduction filters are used to enhance the vein patterns. Principle component analysis is able to reduce the 2-dimensional image database into 1-dimensional Eigen vectors and able to identify all the dorsal hand pattern images.

    Neuroanatomical models hypothesize a role for the dorsal auditory pathway in phonological processing as a feedforward efferent system (Davis and Johnsrude, 2007; Rauschecker and Scott, 2009; Hickok et al., 2011). But the functional organization of the pathway, in terms of time course of interactions between auditory, somatosensory, and motor regions, and the hemispheric lateralization pattern is largely unknown. Here, ambiguous duplex syllables, with elements presented dichotically at varying interaural asynchronies, were used to parametrically modulate phonological processing and associated neural activity in the human dorsal auditory stream. Subjects performed syllable and chirp identification tasks, while event-related potentials and functional magnetic resonance images were concurrently collected. Joint independent component analysis was applied to fuse the neuroimaging data and study the neural dynamics of brain regions involved in phonological processing with high spatiotemporal resolution. Results revealed a highly interactive neural network associated with phonological processing, composed of functional fields in posterior temporal gyrus (pSTG), inferior parietal lobule (IPL), and ventral central sulcus (vCS) that were engaged early and almost simultaneously (at 80-100 ms), consistent with a direct influence of articulatory somatomotor areas on phonemic perception. Left hemispheric lateralization was observed 250 ms earlier in IPL and vCS than pSTG, suggesting that functional specialization of somatomotor (and not auditory) areas determined lateralization in the dorsal auditory pathway. The temporal dynamics of the dorsal auditory pathway described here offer a new understanding of its functional organization and demonstrate that temporal information is essential to resolve neural circuits underlying complex behaviors.

  9. Compound dorsal dislocation of lunate with trapezoid fracture

    2016-12-01

    Full Text Available We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by two Kirschner wires was performed, the trapezoid fracture was conservatively treated. Surgery was followed by immobilization, intense physiotherapy and close follow-up. Even though complaints such as swelling and pain subsided during the course of rehabilitation, partial loss of strength and range of motion remained even after 16 months. In conclusion, a conservative treatment of trapezoid fractures seems to be sufficient in most cases. Closed reduction with Kwire fixation led to an overall satisfactory result in our case. For dorsal lunate dislocations in general, open reduction should be performed when close reduction is unsuccessful or DISI/VISI are observed in radiographs after attempted close reduction.

    There are two highly interconnected clusters of visually responsive areas in the primate cortex. These two clusters have relatively few interconnections with each other, though those interconnections are undoubtedly important. One of the two main clusters (the dorsal stream) links the primary visual cortex (V1) to superior regions of the occipito-parietal cortex, while the other (the ventral stream) links V1 to inferior regions of the occipito-temporal cortex. According to our current understanding of the functional anatomy of these two systems, the dorsal stream's principal role is to provide real-time 'bottom-up' visual guidance of our movements online. In contrast, the ventral stream, in conjunction with top-down information from visual and semantic memory, provides perceptual representations that can serve recognition, visual thought, planning and memory offline. In recent years, this interpretation, initially based chiefly on studies of non-human primates and human neurological patients, has been well supported by functional MRI studies in humans. This perspective presents empirical evidence for the contention that the dorsal stream governs the visual control of movement without the intervention of visual awareness.

  11. Alzheimer disease: functional abnormalities in the dorsal visual pathway.

    2012-02-01

    PURPOSE: To evaluate whether patients with Alzheimer disease (AD) have altered activation compared with age-matched healthy control (HC) subjects during a task that typically recruits the dorsal visual pathway. MATERIALS AND METHODS: The study was performed in accordance with the Declaration of Helsinki, with institutional ethics committee approval, and all subjects provided written informed consent. Two tasks were performed to investigate neural function: face matching and location matching. Twelve patients with mild AD and 14 age-matched HC subjects were included. Brain activation was measured by using functional magnetic resonance imaging. Group statistical analyses were based on a mixed-effects model corrected for multiple comparisons. RESULTS: Task performance was not statistically different between the two groups, and within groups there were no differences in task performance. In the HC group, the visual perception tasks selectively activated the visual pathways. Conversely in the AD group, there was no selective activation during performance of these same tasks. Along the dorsal visual pathway, the AD group recruited additional regions, primarily in the parietal and frontal lobes, for the location-matching task. There were no differences in activation between groups during the face-matching task. CONCLUSION: The increased activation in the AD group may represent a compensatory mechanism for decreased processing effectiveness in early visual areas of patients with AD. The findings support the idea that the dorsal visual pathway is more susceptible to putative AD-related neuropathologic changes than is the ventral visual pathway.

  12. Bulbar urethroplasty using the dorsal approach: current techniques

    Directory of Open Access Journals (Sweden)

    2003-04-01

    Full Text Available INTRODUCTION: The use of flaps or grafts is mandatory in patients with longer and complex strictures. In 1995-96 we described a new dorsal onlay graft urethroplasty. Over time, our original technique was better defined and changed. Now this procedure (also named Barbagli technique has been greeted with a fair amount of enthusiasm in Europe and in the United States. SURGICAL TECHNIQUE: The patient is placed in normal lithotomy position, and a midline perineo-scrotal incision is made. The bulbar urethra is then free from the bulbo-cavernous muscles, and is dissected from the corpora cavernosa. The urethra is completely mobilized from the corpora cavernosa, it is rotated 180 degrees, and is incised along its dorsal surface. The graft (preputial skin or buccal mucosa or the flap is fixed and quilted to the tunica albuginea of the corporal bodies. The right mucosal margin of the opened urethra is sutured to the right side of the patch-graft. The urethra is rotated back into its original position. The left urethral margin is sutured to the left side of the patch graft and to the corporal bodies, and the grafted area is entirely covered by the urethral plate. The bulbo-cavernous muscles are approximated over the grafted area. A 16F silicone Foley catheter is left in place. COMMENTS: Dorsal onlay graft urethroplasty is a versatile procedure that may be combined with various substitute materials like preputial skin, buccal mucosa grafts or pedicled flaps.

  13. Dorsal inlay inner preputial graft for primary hypospadias repair

    Directory of Open Access Journals (Sweden)

    Rajendra B. Nerli

    2014-01-01

    Full Text Available Background: The most commonly performed operation to repair distal hypospadias is the Tubularised incised plate (TIP repair. The key step is midline incision of the urethral plate, which widens a narrow plate and converts a flat into a deep plate groove, ensuring a vertical, slit neomeatus and a normal-calibre neourethra. At times in cases of proximal hypospadias, the urethral plate is very narrow and needs to be augmented or substituted for further tubularisation. We report our experience with primary single stage dorsal inlay urethroplasty using preputial skin grafts. Patients and Methods: Children with proximal hypospadias with a narrow urethral plate formed the study group. Children needing transection of the urethral plate, having undergone circumcision/hypospadias repair previously or having an inadequate prepuce was excluded. Results: Twelve children with a mean age of 48.83 months underwent primary dorsal inlay preputial graft urethroplasty for proximal hypospadias with a very narrow urethral plate. At an average follow-up of 42.16 months, 2 (16.66% children had a breakdown of ventral shaft skin. None of the children had meatal stenosis, and none of these 12 children developed urethrocutaneous fistula. Conclusion: Primary dorsal inlay inner preputial graft urethroplasty successfully fulfills all traditional hypospadias repair criteria. It offers a viable, safe, rapid and easy option in the management of proximal hypospadias with a narrow urethral plate.

    Two middle-aged-patients each presenting with a progressively enlarging mass in the first dorsal web space of their hands are reported. Magnetic resonance imaging (MRI) demonstrated the cause to be a hypertrophic first dorsal inter osseous muscle, with normal T1, T2 and post-gadopentetate dimeglumine signal characteristics. The ability of MRI to diagnose anatomical variants of hand muscles is important in the clinical management of patients with these pseudotumours. The usefulness of magnetic resonance imaging (MRI) in evaluation of soft tissue tumours of the musculoskeletal system is now widely accepted. Its ability to maximize contrast between tumour and adjacent normal tissue in a multiplanar manner makes it the imaging modality of choice in pre-operative staging of soft tissue masses. In the hand and wrist, where benign tumours predominate, MRI may provide a specific diagnosis. We describe two cases in which MRI demonstrated the cause of a hand pseudotumour to be due to hypertrophy of the first dorsal inter osseous muscle.

Los sucesos negativos, dario, enfermedad o muerte de un ser querido, son hechos estresantes, asi como los sucesos positivos; ascender en el trabajo trae consigo el estres del nuevo status, de nuevas responsabilidades. Dentro de los trastornos clinicos vinculados al estres hay alteraciones como: trastornos del sumo, ulceras, dolores de cabeza, aceleracion del ritmo cardiaco y otros trastornos como los cardiovasculares: palpitaciones, hipertension arterial, trastornos digestivos, dolores, ardores, vomitos, nauseas, diarrea o estreriimiento y trastornos cutaneos: donde se presenta transpiracion de manos y pies y problemas alergicos. En el estres se pueden llegar a presentar dos tipos de estres: el positivo y el negativo. Los cuales presentan unas caracteristicas muy particulares, como en el estres negativo: una persona se encuentra ante un nitmero creciente de demandas que le plantean dificultad o constituyen una amenaza, se debe mirar el modo de afrontarlas. En el Estres positivo se presenta cuando la percepcion de capacidad de demanda es mucho mas amplia que las verdaderas demandas. Un aspecto fundamental ante la presencia de estres es la practica necesaria de un deporte o la realizacion de actividades recreativas.

  20. Asymmetric distribution of Echinoid defines the epidermal leading edge during Drosophila dorsal closure

    Science.gov (United States)

    Laplante, Caroline

    2011-01-01

    During Drosophila melanogaster dorsal closure, lateral sheets of embryonic epidermis assemble an actomyosin cable at their leading edge and migrate dorsally over the amnioserosa, converging at the dorsal midline. We show that disappearance of the homophilic cell adhesion molecule Echinoid (Ed) from the amnioserosa just before dorsal closure eliminates homophilic interactions with the adjacent dorsal-most epidermal (DME) cells, which comprise the leading edge. The resulting planar polarized distribution of Ed in the DME cells is essential for the localized accumulation of actin regulators and for actomyosin cable formation at the leading edge and for the polarized localization of the scaffolding protein Bazooka/PAR-3. DME cells with uniform Ed fail to assemble a cable and protrude dorsally, suggesting that the cable restricts dorsal migration. The planar polarized distribution of Ed in the DME cells thus provides a spatial cue that polarizes the DME cell actin cytoskeleton, defining the epidermal leading edge and establishing its contractile properties.

These attempts to provide a coordinated approach to solving environmental problems require methods and tools for spatial analysis and modelling on a continental scale, with river basins being used as spatial units. This paper presents a screening model (Ag-PIE), developed in a GIS environment, for the assessment of pressures from agricultural land use and the consequent impacts on surface and groundwater. Ag-PIE has been applied at the European scale (EU15), with focus on nitrogen pollution from chemical fertilisers and manure. The model adopts a multi-criteria evaluation procedure applied to spatial data layers which represent the variety of factors affecting the pollution process. The DPSIR (Driving forces, Pressures, State, Impact, Responses) approach is applied to provide the modelling approach with a conceptual framework and to further analyse and communicate results. Ag-PIE is ultimately aimed at providing a tool making use of state-of-the-art geographical databases to support policy-makers at the European level. The scale of reference adopted is the river basin, in particular those that extend across national boundaries. The quality of the results obtained has been assessed against existing related studies and monitoring reports and by means of sensitivity analysis. Conclusions are driven by considering the potential of Ag-PIE in devising policy support and its strengths and weaknesses in view of identifying future research needs.

    Nourseothricin (streptothricin) can be inactivated by an acetyl transferase synthesized by E. coli strains containing plasmid pIE 636. Nourseothricin inactivated in the presence of 14C-acetyl-coenzyme A was purified and submitted to partial acidic hydrolysis. By electrophoresis of the hydrolysate a 14C-containing substance moving only slowly towards the cathode could be isolated. This substance after complete hydrolysis yields only unlabelled beta-lysine.

    the most significant stages in the erection of the Millennium Arch outside the Palacio de Congresos, venue for the 12th IBMAC.
    These pictures are divided into six chapters: Background, Components, Springline, Piers, Arch, Centring Erection and Removal, and Trimming.

    A lo largo de la historia, el Arco de fábrica ha sido el componente constructivo más característico de la Arquitectura y la Ingeniería desde que después de sus inicios etruscos en la época romana fuera desarrollado adelantándose con ello a la cultura helénica.
    El Arco, desde entonces, viene empleándose como una solución constructiva eficiente para cubrir espacios con materiales que no soportan tracciones. La originalidad técnica del Arco lo ha llevado a imponerse como símbolo de las hazañas bélicas como era el Arco de Triunfo.
    En el cambio de siglo y milenio en el que nos encontramos, un salto técnico fundamental se desvela en este Congreso, el Sistema de Albañilería Integral, que abre la posibilidad de ampliar el campo de aplicación de la albañilería con la incorporación del acero, a través de las perforaciones de las piezas, lográndose por fin armar en las tres direcciones del espacio cualquier muro de fábrica que se desee.
    El Arco del Milenio conmemoró el 12th IBMAC de Madrid, mostrando en él los avances técnicos que el Sistema de Albañilería Integral permite, al tratarse de un arco inclinado en el espacio y, por tanto, el primer arco de fábrica construido fuera de la vertical, mediante fábrica de Ladriflor aparejada a tizón, reforzada con barras y cercos.

    As part of the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the National Uranium Resource Evaluation (NURE) sponsored by the US Department of Energy (DOE), the Los Alamos Scientific Laboratory (LASL) conducted a detailed hydrogeochemical survey of well waters in a 4250-km/sup 2/ area near Pie Town in west-central New Mexico. A total of 300 well samples was collected and analyzed for uranium and 23 other elements. The results of these analyses and carbonate and bicarbonate ion concentrations are presented in the Appendixes of this report. Uranium concentrations range from below the detection limit of 0.02 parts per billion (ppB) to 293.18 ppB and average 8.71 ppB. Samples containing high levels of uranium were collected from the Largo Creek valley west of Quemado, from a small area about 6 km east of Quemado, from a small area surrounding Pie Town, and from scattered locations in the area surrounding Adams Diggings north of Pie Town. Most of the samples containing high uranium concentrations were collected from wells associated with the volcanic sedimentary facies of the Datil formation. This formation is a likely source of mobile uranium that may be precipitating in the underlying Baca formation, a known uranium host unit. Bicarbonate ion concentration, while proportional to uranium concentration in some cases, is not a strong controlling factor in the uranium concentrations in samples from this area.

  5. A new dual-frequency liquid crystal lens with ring-and-pie electrodes and a driving scheme to prevent disclination lines and improve recovery time.

    A new liquid crystal lens design is proposed to improve the recovery time with a ring-and-pie electrode pattern through a suitable driving scheme and using dual-frequency liquid crystals (DFLC) MLC-2048. Compared with the conventional single hole-type liquid crystal lens, this new structure of the DFLC lens is composed of only two ITO glasses, one of which is designed with the ring-and-pie pattern. For this device, one can control the orientation of liquid crystal directors via a three-stage switching procedure on the particularly-designed ring-and-pie electrode pattern. This aims to eliminate the disclination lines, and using different drive frequencies to reduce the recovery time to be less than 5 seconds. The proposed DFLC lens is shown effective in reducing recovery time, and then serves well as a potential device in places of the conventional lenses with fixed focus lengths and the conventional LC lens with a single circular-hole electrode pattern.

    Passerine birds need extra calcium during their breeding for developing egg shells and proper growth of nestling skeleton. Land snails are an important calcium source for many passerines and human-induced changes in snail populations may pose a severe problem for breeding birds. We studied from the bird's viewpoint how air pollution affects the shell mass, abundance and diversity of land snail communities along a pollution gradient of a copper smelter. We sampled remnant snail shells from the nests of an insectivorous passerine, the pied flycatcher, Ficedula hypoleuca, to find out how the availability of land snails varies along the pollution gradient. The total snail shell mass increased towards the pollution source but declined abruptly in the vicinity of the smelter. This spatial variation in shell mass was evident also within a single snail species and could not be wholly explained by spatially varying snail numbers or species composition. Instead, the total shell mass was related to their shell size, individuals being largest at the moderately polluted areas. Smaller shell size suggests inferior growth of snails in the most heavily polluted area. Our study shows that pollution affects the diversity, abundance (available shell mass) and individual quality of land snails, posing reproductive problems for birds that rely on snails as calcium sources during breeding. There are probably both direct pollution-related (heavy metal and calcium levels) and indirect (habitat change) effects behind the observed changes in snail populations. Copyright 2010 Elsevier B.V.

    Quaternary tectonic and denudation rates are investigated for an actively growing basement anticline: the Sierra Pie de Palo range, which belongs to the Andean foreland of Northwestern Argentina (28°S-33°S). In this study, a detailed morphometric analysis of the topography is combined with in situ-produced cosmogenic10Be concentrations measured in (1) surface boulders abandoned on alluvial terraces affected by fault activity (along the north bounding fault) and growth of the basement fold (along the southeastern border), (2) bedrock outcrops corresponding to an exhumed and folded, regional erosion surface, and (3) fluvial sediments sampled at the outlets of several watersheds. Along the eastern and northern borders of the range, incision and uplift rates have been estimated at approximately 0.5 and 1 mm/yr when integrated on Holocene and Pleistocene time scales, in close agreement with both long-term (structural and basin evolution data) and short-term (GPS-derived velocity field) analyses. Cosmogenic-derived denudation and uplift rates combined with geomorphic characteristics of watersheds and river channels allows estimating the onset of the uplift at 4-6 Ma, followed by a more recent period of topographic rejuvenation at roughly 1-2 Ma, probably synchronous with steepening of the eastern and northern flanks of the anticline.

    The purpose of this study was to describe the distal pathway of the dorsal nerve of the clitoris (DNC) from gross anatomical and histological studies of cadaver specimens. We performed dissections on 14 intact adult cadaver vulva specimens using 2× loupe magnification and microscopy. The DNC was identified by gross dissection and confirmed histologically by staining with hematoxylin and eosin (H&E), Masson's trichrome (MT), and S100 antibody. The DNC pathway and its branches were followed from the pubic rami to the glans clitoris. The DNC travels inferior to the inferior pubic ramus along the superior/posterior edge of the clitoral crus. At the angle of the clitoral body, inferior to the pubic symphysis, the DNC enters the deep component of the suspensory ligament, which attaches to the clitoral body and to the pubic symphysis. The dorsal nerves, at the angle of the clitoral body, travel along the dorsal aspect of the clitoral body at the 11 and 1 o'clock positions. At the base of the clitoral body, the DNC is suspended superiorly away from the tunica. Distally along the clitoral body, the DNC descends and runs along the tunica and enters the glans. Within the glans, the terminal fibers are widely dispersed, and numerous receptors populate the supporting tissue of the glans beneath the epithelium. The detailed description of the distal course of the nerve presented here has not been previously described in adult humans and is pertinent for surgical procedures involving the clitoris.

    Full Text Available Meningiomas are benign in nature and arise from the arachnoid cells. They are mostly situated in the intracranial compartment, whereas spinal meningiomas are rare. Approximately, in 10% of cases, an extradural component is seen but an exclusively extradural meningioma is quite uncommon. However, WHO Grade II (atypical and Grade III (anaplastic tumors can behave aggressively. We reported a case of purely extradural psammomatous meningioma in an adult male affecting the dorsal spine although uncommon meningiomas should be included in the differential diagnosis of extradural intraspinal masses.

    The ergonomic analysis of a control or a supervision workstation for a vehicle or a process, necessitates to take into account the biomecanical visuo-postural system. The measurements, which are necessary to do, must give informations about the spatial direction of the limbs, the dorsal shape, eventually the eyes direction, and the postural evolution during the working time. More, the smallness of the work station, the backrest and sometime a vibratory environment made use specific, strong and small devices wich do not disturb the operator. The measurement system which we propose is made of an optical device. This system is studied in relation with the french "Institute de Recherche pour les Transports" for an ergonomic analysis of a truck cabin. The optical device consists on placing on the body of the driver on particular places materializing specially members and trunck joint points, some drops which reflect the infra-red raies coming from a specific light. Several cameras whose relative positions depend on the experiment site, transmit video signals to the associated treatment systems which extract the coordinates (Xi, Yi) of each drop in the observation scope of any camera. By regrouping the informations obtained from every view, it is possible to obtain the spatial drop position and then to restore the individual's posture in three dimensions. Therefore, this device doesn't enable us, in consideration of the backrest, to analyse the dorsal posture, which is important with regard to dorsal pains frequency. For that reason, we complete the measurements by using a "curvometer". This device consists of a flexible stick fixed upon the individual back with elastic belts, whose distorsions (curvature in m-1) are measured, in the individual's sagittal plane, with 4 strain gauges pairs; located approximately at the level of vertebra D1, D6, D10 and L3. A fifth measurement, concerning the inclination (in degree) of the lower part of the stick, makes it is possible to

    2016-01-01

    The management of cerebral palsy (CP) is complex and requires a multidisciplinary approach. Selective dorsal rhizotomy (SDR) is a neurosurgical technique that aims to reduce spasticity in the lower limbs. A minimally invasive approach to SDR involves a single level laminectomy at the conus and utilises intraoperative electromyography (EMG). When combined with physiotherapy, SDR is effective in selected children and has minimal complications. This review discusses the epidemiology of CP and the management using SDR within an integrated multidisciplinary centre. Particular attention is given to the single-level laminectomy technique of SDR and its rationale, and the patient workup, recovery and outcomes of SDR. PMID:27757432

    We report on a new-born with a congenital mucocele on the anterior dorsal side of the tongue. The presentation as well as the differential diagnosis of congenital oral swellings is discussed. Because of breastfeeding problems the mucinous swelling was incised and drained two days after birth. Immediately after drainage the swelling disappeared. Congenital oral swellings are rare. Most of them are mucoceles. Post-partum treatment is surgically, but spontaneous remission has been described. High incidence of recurrence should be taken into account when (micro-)marsupialization or incision as sole treatment is performed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2007-10-01

    We present a case of a child with Patau syndrome that exhibits features consistent with congenital palmar nail syndrome. The literature is reviewed and evidence presented to demonstrate that this is a defect in the dorso-ventral patterning of the limb and thus a form of dorsal dimelia. In order to differentiate this from other instances of ectopic nail tissue we suggest congenital palmar nail syndrome should be more specifically defined as duplicated nails, absent flexion creases, non-glabrous skin on the palmar surface, reduced movement at the interphalangeal joints and hypoplastic terminal phalanges.

  20. Language development and the ontogeny of the dorsal pathway

    2012-02-01

    Full Text Available In the lack of clear phylogenetic data on the neurobiological basis of the evolution of language comparative data across species and ontogenetic data from humans may inform us about the possible neural prerequisites of language. In the adult human brain the language-relevant regions in the frontal and temporal cortex are connected by different pathways: ventral and dorsal pathways. Ontogenetically, it is shown that newborns display an adult-like ventral pathway at birth. The dorsal pathway involving the arcuate fasciculus and the superior longitudinal fasciculus seems to display two subparts in the adult brain: one connecting the temporal cortex to the premotor cortex and one connecting the temporal cortex to Broca’s area. While the former subpart is present at birth, the latter develops much later and is even not fully matured at the age of seven years, an age when children still have problems in processing syntactically complex sentences. We therefore suggest that the mastery of complex syntax which is a core of human language crucially depends on the connection between the temporal cortex and Broca’s area.
