    Mycotic aneurysms of the aorta and the visceral arteries are life-threatening diseases, due to potential rupture and organ or limb ischemia. They occur in endocarditis, immunodeficiency, bacteremia and fungemia, and have a poor prognosis.We report on a case of a 54-year-old male patient suffering from abdominal angina after mitral valve replacement for septic mycotic endocarditis. In presence of a mycotic-embolic occlusion of the left popliteal artery and multiple septic organ infarctions a mycotic aneurysm of the superior mesenteric artery was found in abdominal spiral-CT.Based on sequential spiral-CT examinations, this case demonstrates the development of a septic aneurysm of the superior mesenteric artery. (orig.) [German] Mykotische Aneurysmen der Aorta und ihrer Aeste stellen wegen Rupturgefahr und moeglicher Minderperfusion von Organen und Extremitaeten eine lebensgefaehrliche Erkrankung mit unguenstiger Prognose dar. Beguenstigende Faktoren sind geschwaechte Immunabwehr, Endokarditis, Bakteriaemie und Fungaemie.Wir berichten ueber einen 54-jaehrigen Patienten, der nach einem Mitralklappenersatz bei mykotischer Endokarditis zunehmende abdominelle Beschwerden im Sinne einer Angina abdominalis entwickelte. Die abdominelle Spiralcomputertomographie zeigte ein mykotisches Aneurysma der A. mesenterica superior. Daneben bestanden ein mykotischer Verschluss der linken A. poplitea und multiple septische Organinfarkte.Der Fall demonstriert anhand sequentieller Computertomographien eindrucksvoll die Entwicklung eines septischen Viszeralarterienaneurysmas.

    Full Text Available A thorough knowledge of arteries of the upper extremity is necessary for catheterization, graft harvesting, shunt application, and Astrup’s examination. Coincidences of two different variants are rather rare. We present a case of the coincidental presence of arteria brachialis accessoria stemming from the arteria axillaris and reuniting with the arteria brachialis 1.5cm below the origin of the arteria collateralis ulnaris inferior; and arteria comitans nervi median originated in association with the arteria interossea communis from the arteria ulnaris, passing into the palm and towards the arteriae digitales palmares to the thumb, index and lateral side of the third finger. Such coincidence has never been reported before.

    cerebrale, retro-orbitaria e splancnica (splenoportale, mesenterica e renale) nei pazienti derodermici. Materiale e metodi. Il gruppo di studio (GS) e composto da 50 pazienti affetti da sclerodermia con anamnesi negativa per malattie cerebrovascolari, epatopatie, nefropatie e oftalmopatie. In tutti i pazienti e stata studiata la vasodilatazione endotelio-mediata dell'arteria brachiale tramite la misurazione del diametro trasverso con sonda ad alta risoluzione; sono stati anche misurati l'indice di resistenza (IR) delle arterie cerebrale media, centroretinica, epatica propria, mesenterica superiore e renali, in condizioni basali e dopo tre giorni di terapia. AI fine di valutare la variabilita intra-osservatore delle misurazioni, e stato reclutato un gruppo di controllo (GC) composto da 10 volontari sani che sono stati studiati con il medesimo protocollo Doppler e rivalutati a distanza di tre giorni senza ricevere alcuna terapia. Risultati. Il GS ha dimostrato un significativo incremento della dilatazione endotelio-mediata dell'arteria brachiale, del diametro e della velocita media di flusso portale, dell'IP dell'arteria splenica all'ilo (pre-Prostavasin vs post-Prostavasin, p < 0,001). AI contrario il GC non ha mostrato significative variazioni dei parametri considerati. Gli IR delle arterie cerebrale media, centroretinica, renale, epatica propria e mesenterica superiore si sono ridotti dopo terapia nella maggioranza dei pazienti del GS pur non risultando statisticamente significativi. Conclusioni. Nel campione esaminato il Prostavasin ha dimostrato una potente azione vasodilatatoria prevalentemente a livello periferico ed ha incrementato la velocita media di flusso portale ed il diametro della vena porta, ma anche l'IP dell'arteria splenica all'ilo, non supportando l'ipotesi formulata da altri autori di una sua azione mirata e specifica sulle resistenze intraepatiche.

    Full Text Available Antecedentes. El conocimiento exacto de la integración anatomofisiológica del sistema de conducción del corazón, es fundamental para la comprender la fisiopatología, el diagnóstico y el manejo de muchas de las complicaciones de la enfermedad coronaria y de las cardiopatías en general. Uno de los aspectos fundamentales, más variable y con mayores repercusiones clínicas corresponde al origen y recorrido de las arterias encargadas de irrigar el nódulo sinoatrial. Objetivo. Determinar el origen, recorrido y distribución de las arterias que irrigan el nódulo sinoatrial en una muestra de población colombiana.  Material y métodos. La muestra de análisis fueron 60 bloques cardiopulmonares y digestivos seleccionados a través de muestreo por conveniencia. A estos se les realizó una disección convencional de los genitales para la determinación del sexo y posteriormente se procedió con la disección de las arterias coronarias específicamente de la arteria del nódulo sinoatrial, con el fin de establecer su origen y recorrido. Resultados. Como hallazgo principal se encontró que el origen de la arteria del nódulo sinoatrial en 75% provenía  de la coronaria derecha, un 15% procedía de la arteria circunfleja y el 10% restante fue codominante. En cuanto al trayecto 86,6% fueron lineales, mientras 13,4% tuvieron formas alternas como Y, doble Y o en tridente. Conclusiones. Se evidenció predominio del  origen de la arteria del nódulo sinoatrial en la coronaria derecha, hallazgo coincidente con investigaciones similares e independiente de la procedencia geográfica y el origen racial. Sin embargo, en este estudio se evidenciaron  recorridos no reportados en la literatura como la distribución en Y, en doble Y, en K invertida y en tridente.

    Full Text Available El conocimiento preciso de los patrones vasculares permite mejorar los resultados de la reconstrucción regional del pabellón auricular y el diseño de colgajos regionales dependientes de la arteria temporal superficial para la reconstrucción facial. En México, no contamos en la actualidad con descripciones anatómicas de las variantes vasculares normales de la arteria temporal superficial. El objetivo de este trabajo es la descripción de las variantes anatómicas de la arteria temporal superficial a través de la disección de este vaso en 12 regiones tempo-parieto-occipitales en cadáveres. Nuestros resultados muestran que la arteria temporal superficial siempre se divide en dos ramas, una anterior y otra posterior, la distribución de ésta se sitúa en el cuarto más posterior de la región temporal, con una bifurcación alta. La distribución de la anatomía vascular, tomando en cuenta el calibre mayor de la arteria temporal superficial con respecto a la arteria auricular posterior, la ausencia de esta última en 4 de las regiones estudiadas, así como la distancia de dichos vasos con respecto al conducto auditivo externo, sugieren que en nuestra población la irrigación del pabellón auricular depende de la arteria temporal superficial, restándole importancia a la aportación del riego sanguíneo de esta región por parte de la arteria auricular posterior. Nuestro estudio arroja resultados que indican la existencia de variaciones importantes en la anatomía vascular regional que justifican la realización de estudios posteriores que permitan una descripción mas detallada de la misma para aumentar el éxito de las intervenciones quirúrgicas.

    Full Text Available La arteria vertebral es una de las arterias que irriga el cerebro. El conocimiento de la anatomía normal y las variantes de la arteria vertebral adquiere importancia en la práctica clínica y la radiología vascular. El origen anómalo de la arteria vertebral del arco de la aorta o cualquiera de las arterias del cuello ha sido reportado por muchos autores. En este informe se presenta una variación del curso prevertebral de la arteria vertebral izquierda. La arteria vertebral tenía su origen habitual en la arteria subclavia con un largo curso prevertebral y entraba en el foramen transversarium de la vértebra CII. El origen y recorrido de la arteria vertebral en el lado derecho fue normal. Clínicamente es importante conocer el origen y curso del segmento prevertebral de la arteria vertebral y las posibles variaciones. El presente informe debería ser de interés para el médico vascular con respecto a las variaciones en el cuello y región torácica, y puede dar idea para dilucidar el mecanismo de desarrollo de la angiogénesis. Vertebral artery is one of the arteries supplying the brain. Knowledge of the normal and variant anatomy of the vertebral artery assumes importance in clinical practice and vascular radiology. Anomalous origins of the vertebral artery from the arch of the aorta or any one of the arteries of the neck have been reported by several authors. In this report a variation of the prevertebral course of the left vertebral artery is being presented. The Vertebral artery had usual origin from the subclavian artery and had a longer prevertebral course to enter the foramen transversarium of the CII vertebra. The origin and course of the vertebral artery on the right side was normal. It is clinically important to know the origin and course of the prevertebral segment of the vertebral artery and possible variations. The present report should be of interest for clinicians with regard to vascular variations in the neck and thoracic

    Full Text Available Las quemaduras eléctricas producen lesiones profundas, especialmente las debidas a la entrada y salida de la corriente y al arco voltaico, que pueden dejar expuestas estructuras nobles y afectar áreas de flexo-extensión, como la fosa antecubital. Los defectos resultantes pueden cubrirse mediante colgajos libres o pediculados de brazo y antebrazo. Entre las distintas opciones quirúrgicas, el colgajo medial del brazo evita la interrupción de los ejes vasculares mayores y la secuela en la zona donante es discreta. Sin embargo, su uso está poco extendido por considerarse un colgajo de difícil disección debido a la variabilidad anatómica de las arterias colaterales cubitales superior e inferior que lo irrigan. Presentamos la cobertura para un defecto secundario a quemadura eléctrica en la fosa antecubital mediante un colgajo medial del brazo basado en las ramas perforantes de la arteria colateral cubital inferior. Aunque confirmamos en este caso la variabilidad vascular, la disección resultó sencilla y el resultado estético y funcional fue excelente.

    Full Text Available La endotelina-1 es un péptido vasoconstrictor producido por el endotelio vascular, cuyos niveles plasmáticos están aumentados en los pacientes con cáncer colorrectal y que puede participar en la regulación del flujo sanguíneo tumoral. Para estudiar si la respuesta a este péptido está alterada en las arterias tumorales, se obtuvieron, de 13 pacientes intervenidos quirúrgicamente por cáncer colorrectal, arterias mesentéricas irrigando el tumor y arterias mesentéricas de una región alejada del tumor, y asimismo se obtuvieron arterias mesentéricas de pacientes intervenidos por diverticulitis (n = 4 o enfermedad inflamatoria intestinal (n = 3. Las arterias mesentéricas se montaron en una preparación para el registro de la contracción isométrica en un baño de órganos, encontrándose que la endotelina-1 producía contracción en los tres tipos de arterias, pero la sensibilidad a este péptido fue mayor en las arterias irrigando el tumor que en las arterias alejadas del tumor o en las arterias de pacientes sin patología tumoral. Estos resultados indican que la endotelina-1 puede regular el flujo sanguíneo en los tumores colorrectales, produciendo una mayor vasoconstricción en las arterias que irrigan el tumor que en las arterias no tumorales.Endothelin-1 is an endothelium-derived vasoconstrictor peptide whose plasma levels are increased in patients with colorectal cancer, and which may be involved in tumor blood flow regulation. To study whether response to this peptide is altered in tumor arteries, mesenteric arteries supplying blood flow to colorectal tumors, and mesenteric arteries far from said tumors were obtained from 13 patients undergoing colectomy; mesenteric arteries were also obtained from patients with diverticulitis (n = 4 or inflammatory bowel disease (n = 3.

In accordance to data of ultrasound Doppler flowmetry for the blood flow along portal vein, a. hepatis communis, a. mesenterica superior in complicated pancreatic pseudocysts compensatory--adaptive reactions on level of hepatic--spanchnic blood flow are directed towards restriction of the blood inflow through the portal vein system. This is accompanied by the common peripheral vascular resistence raising in basin of a. mesenterica superior, which have depended upon the patients' state severity, caused by reduction of the volume blood flow in a certan vascular collector. The oxygen debt of the liver in these patients is compensated by the volume blood flow enhancement along a. hepatis communis.

    Full Text Available Las variaciones en el curso de la arteria maxilar se describen a menudo, con sus relaciones con el músculo pterigoideo lateral. En el presente caso informamos una variación exclusiva en el curso de la arteria maxilar que no fue publicada antes. En un cadáver masculino de 75 años arteria maxilar derecho estaba pasando por el bucle del nervio auriculo-temporal. La arteria meníngea media provenía de la arteria maxilar con un bucle del nervio auriculo-temporal. La arteria maxilar pasaba profunda con respecto al nervio dentario inferior pero superficial al nervio lingual. El conocimiento de estas variaciones es importante para el cirujano y también serviría para explicar la posible participación de estas variaciones en la etiología del dolor mandibular. Variations in the course of the maxillary artery are often described with its relations to the lateral pterygoid muscle. In the present case we report a unique variation in the course of the maxillary artery which was not reported before. In a 75 years old male cadaver the right maxillary artery passed through the loop of the auriculotemporal nerve. The middle meningeal artery was arising from the maxillary artery within the nerve loop of auriculotemporal nerve. Further the maxillary artery passed deep to the inferior alveolar nerve but superficial to the lingual nerve. The knowledge of these variations is important for surgeons and it would also explain the possible involvement of these variations in etiology of the craniomandibular pain.

    Full Text Available The prevalence of diabetes mellitus (DM, a chronic disease with hyperglycemia and impaired immune function, is increasing worldwide. Progression from impaired glucose tolerance (IGT to type 2 DM has recently become a target for early intervention. The fruiting bodies (FB and submerged culture mycelium (CM of Tremella mesenterica, an edible and medicinal mushroom, have been demonstrated to have antihyperglycemic and immunomodulatory activities in type 1 DM rats. Herein, we investigated the effects of acidic polysaccharide glucuronoxylomannan (GX extracted from CM on the immunocyte responses. Male Wistar rats were injected with streptozotocin (65 mg/kg plus nicotinamide (200 mg/kg for the induction of IGT, and gavaged daily with vehicle, FB, CM, or GX (1 g/kg/day. Rats injected with saline and gavaged vehicle were used as controls. Two weeks later, peripheral blood leukocytes (PBLs and splenocytes were collected. Ingestion of FB, CM, and GX significantly decreased blood glucose levels in the postprandial period and in oral glucose tolerance test, and partially reversed T-splenocytic proliferation in IGT rats. CM significantly decreased T-helper lymphocytes in the PBLs and B-splenocytes. In addition, FB, CM, and GX significantly reversed the IGT-induced decreases in tumor necrosis factor-α production; GX significantly increased interleukin-6 production in T-lymphocytes in the PBLs and splenocytes; and CM and GX significantly reversed IGT-induced decrease in interferon-γ production in T-lymphocytes in the spleen. In conclusion, FB, CM, and acidic polysaccharide GX of T. mesenterica may increase T-cell immunity via the elevation of proinflammatory and T-helper cytokine production in rats with impaired glucose tolerance.

    Full Text Available IntroducciónEl origen anómalo de la arteria coronaria izquierda en la arteria pulmonar es una cardiopatía congénita rara que produce isquemia miocárdica con disfunción ventricular izquierda e insuficiencia mitral de grado variable. Las técnicas actuales han modificado la historia natural de esta enfermedad mediante el restablecimiento de un sistema de doble irrigación coronaria.ObjetivosEvaluar la experiencia institucional en la corrección quirúrgica del origen anómalo de la coronaria izquierda en la arteria pulmonar.Material y métodosEntre febrero de 2000 y mayo de 2008 fueron operados 13 pacientes con este diagnóstico. Seis eran menores de 1 año; mediana: 2,5 años; rango: 45 días a 21 años. Antes de la cirugía, el 61% de los pacientes presentaban insuficiencia cardíaca, el 69% signos de infarto y el 84% cardiomegalia moderada a grave. La fracción de acortamiento promedio era del 26,07% y existía insuficiencia mitral moderada a grave en el 46% de los casos. El diagnóstico se confirmó por cateterismo en 11 pacientes.En un paciente se realizó cirugía de Takeuchi y en los 12 restantes se efectuó el reimplante de la coronaria izquierda en la aorta. En un paciente se realizó plástica mitral. Seis recibieron perfusión y cardioplejía de la coronaria anómala por la arteria pulmonar.ResultadosLa mortalidad al presente, con un seguimiento promedio de 74,76 meses, es del 0%. Ningún paciente presentaba insuficiencia cardíaca al alta. En 9 de los 11 pacientes con cardiomegalia, ésta se redujo. La fracción de acortamiento promedio posoperatoria fue del 39,92%. La insuficiencia mitral disminuyó en todos los que la presentaban, excepto en uno. Ninguno presentó insuficiencia grave en el posoperatorio alejado.ConclusionesLos resultados de la cirugía correctora del origen anómalo de la coronaria izquierda en la arteria pulmonar son excelentes en todos los grupos etarios, con mejoría significativa de la función mioc

    Full Text Available Los aneurismas del complejo arteria cerebral anterior-arteria comunicante anterior figuran entre los más frecuentes de localización intracraneal y, debido a su variabilidad anatómica y características hemodinámicas, constituyen un reto especial para cualquier esfuerzo terapéutico. Con el objetivo de caracterizarlos y evaluar los resultados del tratamiento quirúrgico de estas lesiones, se estudian los pacientes operados en el Servicio de Neurocirugía del Hospital Clinicoquirúrgico «Hermanos Ameijeiras», entre enero de 1983 y agosto de 1998. Se observó que el 71,1 % de la muestra egresó en excelente estado; el 13,44 %, con secuelas mínimas; el 3,48 %, con secuelas graves y que la mortalidad fue del 11,53 %. Se concluye que estos aneurismas son más frecuentes en el sexo masculino, en la cuarta y quinta décadas de la vida (media de 39,9 años y que el tamaño crítico de ruptura se ubica mayoritariamente entre 6 mm y 11 mm. De igual forma se observó que la edad, el tamaño sacular, el vasoespasmo y la ruptura transoperatoria influyen sobre los resultados y que la influencia de estas dos últimas complicaciones es muy fuerte. El infarto cerebral isquémico fue la causa de muerte más frecuente

    Full Text Available Se presenta el caso de un paciente de 32 años que presentó síntomas de fibrilación ventricular mientras estaba practicando una maratón. El estudio diagnóstico puso de manifiesto la existencia de un origen anómalo de la arteria coronaria derecha en el seno coronario izquierdo, con trayecto no intramural entre la aorta y la arteria pulmonar. La reparación quirúrgica consistió en la realización de una anastomosis laterolateral de la coronaria derecha al seno aórtico derecho. El postoperatorio del paciente transcurrió con normalidad. El origen aórtico anómalo de las coronarias es una alteración congénita rara asociada a un mayor riesgo de muerte súbita. En muchos casos la enfermedad es asintomática hasta producirse el infarto o la arritmia ventricular. Cuando la coronaria sigue un trayecto intramural la corrección mediante el unroofing es la técnica más empleada. Si no hay trayecto intramural y la translocación no es posible, la técnica descrita constituye una alternativa válida.

    Full Text Available Objetivo: Determinar las características anatómicas de las arterias coronarias del cerdo, mediante inyección con látex. Materiales y métodos: Se usaron 100 corazones de cerdo. Se insertaron sondas Nelaton a través de las arterias coronarias y se les inyectó solución de látex y tinta china. Se determinó el diámetro y el punto de origen para la coronaria derecha, coronaria izquierda, interventricular paraconal y circunfleja. Se cuantificaron el número de ramas diagonales, marginales ventriculares izquierdas y postero laterales. Se determinó frecuencia de ramus intermedius y tipo de dominancia. Se realizó análisis estadístico con un error estándar del 5%, con el Epidat 3,1. Resultados: El 100% de los orígenes anatómicos de las arterias coronarias fueron normales. La dominancia mas frecuente fue la derecha, 73%. El promedio de número de ramas marginales izquierdas, diagonales y posterolaterales fue de 3. La frecuencia de ramus intermedius fue de 12%. El calculo de chi cuadrado de Pearson mostró significancia entre el ramus intermedius y número de ramas marginales izquierdas (p=0,0009. Conclusiones: Las características anatómicas de las arterias coronarias del cerdo son similares a las del humano. El ramus intermedius se comporta como una primera rama marginal izquierda y no como una primera rama diagonal como lo afirman algunos autores.

Sintetizamos la patogenia de los aneurismas en cuatro hechos fundamentales: los aneurismas vestigiales originados en brotes vasculares no desarrollados o que no han involucionado normalmente; la falta de desarrollo de la túnica elástica en la zona de bifurcación de los grandes vasos; la arterioesclerosis; los procesos inflamatorios de la túnica media (sífilis y micosis. Hacemos un estudio clínico de los aneurismas del complejo cerebral-comunicante anterior, llamando la atención sobre aquellos en los que, a las hemorragias subaracnoidales, se asocian manifestaciones en el fondo de ojo, trastornos psíquicos y fenómenos motores. Llamamos la atención sobre las formas pseudo-tumorales quiasmáticas y los denominados aneurismas trombosantes que originan el síndrome progresivo fronto-cíngulo-calloso. Estudiamos la radiología simple de los aneurismas de esta región, llamando la atención sobre las calcificaciones cirsoideas suprasellares y los fenómenos de erosión de la silla turca. Llamamos la atención sobre la importancia de la arteriografía para confirmar el diagnóstico, estudiar la circulación colateral, el tamaño, la forma y el pedículo del aneurisma, elementos fundamentales para el plan operatório. En el tratamiento quirúrgico descartamos, por ineficaz, la ligadura de la carótida interna en el cuello. Es fundamental el abordaje intracraneano por vía subfrontal en los aneurismas de la porción précomunicante y comunicante con desarrollo hacia abajo, mientras que, la via sagital-frontal se utilizará en los aneurismas de desarrollo hacia arriba ya sea de la comunicante o de la porción distal de la arteria cerebral anterior o sus ramas.

    Full Text Available Knowledge of variations at and in the surroundings of cubital fossa is useful for the orthopedic surgeons, plastic surgeons and medical practitioners in general. During routine dissection, we observed arterial and muscular variations in and around the cubital fossa. The brachial artery terminated 2 inches above the base of the cubital fossa. The radial and ulnar arteries entered the cubital fossa by passing in front of the tendons of brachialis and biceps brachii respectively. The ulnar artery was surrounded by the third head of pronator teres which took its origin from the fascia covering the distal part of the brachialis muscle. This muscle joined pronator teres tendon distally and was supplied by a branch of median nerve. This muscle could alter the blood flow in the ulnar artery and may cause difficulties in recording the blood pressure.El conocimiento de las variaciones en los alrededores de la fosa cubital es útil para cirujanos ortopédicos, cirujanos plásticos y médicos en general.

    Full Text Available The aim of this paper was to describe the branching schema of the ventral branches of the abdominal aorta: the a. celiaca, the a. mesenterica cranialis and the a. mesenterica caudalis. The study was carried out on nine adult European hares using the corrosion cast technique. After the euthanasia, the vascular network was perfused with saline. Batson’s corrosion casting kit No. 17 was used as a casting medium. After polymerisation of the medium, the maceration was carried out in KOH solution. In all specimens, the first branch originating from the a. celiaca was the a. lienalis. The a. hepatica was present as the second branch in four cases and as the third branch also in four cases. The first branch of the a. mesenterica cranialis was the a. colica media in seven cases. The second branch was represented by the a. pancreaticoduodenalis caudalis also in seven cases. Two aa. jejunales originated as the third branch. In seven cases, the fourth branch formed the truncus jejunalis and the fifth branch the a. ileocecalis. The a. mesenterica caudalis had a uniform arrangement in all of the specimens. The results enabled us to conclude that there was higher variability of the branching pattern of the a. celiaca in comparison with the a. mesenterica cranialis and the a. mesenterica caudalis in the European hare.

    Full Text Available This article reviews in detail the superficial brachiomedian artery (arteria brachiomediana superficialis, a very rare variant of the main arterial trunks of the upper limb. It branches either from the axillary artery or the brachial artery, descends superficially in the arm (similar to the course of the superficial brachial artery and continues across the cubital fossa, runs superficially in the forearm, approaches the median nerve and enters the carpal canal to reach the hand. It usually terminates in the superficial palmar arch. The first drawing was published, in 1830, and the first description was published, in 1844. Altogether, to our knowledge, only 31 cases of a true, superficial brachiomedian artery have been reported (Some cases are incorrectly reported as superficial brachioradiomedian artery or superficial brachioulnomedian artery. Based on a meta-analysis of known, available studies, the incidence is 0.23% in Caucasians and 1.48% in Mongolians. Knowing whether or not this arterial variant is present is important in clinical medicine and relevant for: The catheterization via the radial or ulnar artery; harvesting the vascular pedicle for a forearm flap based on the radial, ulnar or superficial brachiomedian arteries; the possible collateral circulation in cases of the arterial closure; and the surgical management of carpal tunnel syndrome. Its presence can elevate the danger of an injury to the superficially located variant artery or of an accidental injection.

No obstante debe insistirse en el estudio arteriográfico en casos sospechosos sin evidencia clínica. Se ilustran varios casos con el problema de manejo clínico que plantea este grupo de pacientes. El tratamiento ideal es el quirúrgico el cual debe hacerse precozmente y consiste en restablecer la continuidad vascular por diversos procedimiento que incluyen los injertos venosos, las suturas y anastomosis primarias y los puentes venosos. Se pueden tener controles arteriográficos operatorios que demuestran un buen lecho distal. Se debe trabajar en equipo con ortopedistas y la reducción ortopédica debe preceder al procedimiento vascular; señalamos una cifra de amputación de sólo el 12.5 por ciento que consideramos baja si comparamos con otros informes de la literatura mundial y otra comunicación de este mismo hospital. Finalmente nuestra mortalidad es del 0 por ciento.

    Full Text Available Las ramas precoces de la arteria cerebral media son ramas corticales originadas del tronco de la citada arteria. Se trata de arterias que pueden nutrir importantes áreas de los lóbulos temporal, frontal o la ínsula. Por lo tanto, la oclusión de una de estas ramas producirá un área de isquemia con potenciales consecuencias. Se estudiaron 20 hemisferios cerebrales  de cadáveres adultos conservados en formol, y 20 angiografías silvianas realizando una comparación y correlación. En las piezas anatómicas, la arteria cerebral media terminó por bifurcación en el 100% de los casos y dicha bifurcación se sitúo en la porción esfenoidal (M1 en la mayoría de las piezas. Se encontraron ramas precoces en número de1 a4 en el 80%, totalizando 28 arterias, de las cuales 23 tenían destino temporal y 5 frontales. En el material angiográfico la cerebral media terminó por bifurcación en el 95% de los casos y la misma se ubicó en M1 en la mayoría de los casos. Se encontraron ramas precoces en el 70% de los estudios analizados, totalizando 19 ramos. De los mismos, 16 fueron temporales, 1 frontal y en 2 casos no se pudo determinar su destino. Consideramos que los datos anatómicos y angiográficos obtenidos por este y otros estudios son de utilidad en la planificación del clipado de  los aneurismas de la cerebral media. The early branches of the middle cerebral artery are cortical branches that arise from the trunk of this artery. These branches can supply significant areas in the temporal, frontal or insular lobes. Therefore, their occlusion may lead to ischemia and potential sequelae. We studied 20 cerebral hemispheres of formalin-fixed adult cadavers and 20 silvian angiographies in order to compare and correlate them.

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para segmentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El algoritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1 Los procesamientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2 Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la estenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el concurso “Carotid Lumen Segmentation and Stenosis Grading Grand Challenge” 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80.4% comparado con la segmentación de referencia, y el error promedio de la cuantificación de estenosis fue 14.4%.

    Full Text Available La disección cuidadosa del tercio posterior de la parte superficial de la glándula salival submandibular es uno de los pasos quirúrgicos esenciales en la extirpación endoscópica glandular, evitando daños en la arteria facial. Un buen conocimiento de la poco común relación entre la arteria facial y la glándula salival submandibular es de vital importancia para llevar a cabo de forma eficiente y segura la extirpación de la glándula submandibular. Las variaciones del patrón de ramificación de la arteria facial son bien conocidas y han sido expuestas en el pasado. Sin embargo, las variaciones en su origen y trayectoria son poco frecuentes. Durante una rutinaria disección de cabeza y cuello para los estudiantes universitarios de Medicina, observamos la inusual trayectoria de la arteria facial en el triángulo digástrico derecho en un cadáver de un varón de origen indio de aproximadamente 60 años. La arteria facial derecha se originó de la común lingual-facial del tronco por encima del nivel del asta mayor del hueso hioides, y luego atravesar a través de la sustancia de la parte superficial de la glándula submandibular, sin la formación de un bucle. Después la arteria entraba en la cara por el ángulo anteroinferior del masetero. A continuación, en su trayectoria intraglandular, esta arteria mostraba pequeñas ramificaciones glandulares.  Careful dissection of the posterior one third of the superficial part of the submandibular salivary gland is one of the essential surgical steps in endoscopic glandular excision, to avoid injury to the facial artery. A sound knowledge of unusual relationship of the facial artery with the submandibular salivary gland is essentially important to perform the safe and efficient submandibular gland excision. Different types of variations in the branching pattern of the facial artery have been reported in the past. However, variations in the origin and course of the facial artery are very rare

    techniques, endovascular treatment is feasible in nearly all SAAs. It ensures good immediate and long term results, and no doubt presents some advantages in comparison to surgical treatment, as it less invasive and allows the preservation of splenic function. [Italian] Scopo. Verificare l'efficacia del trattamento endovascolare degli aneurismi dell'arteria splenica (AAS). Materiale e metodi. Nel periodo compreso tra maggio 2000 e giugno 2003 sono stati trattati 11 AAS veri in 9 pazienti (7 femmine e 2 maschi; eta media 58 anni), 8 sacciformi e 3 fusiformi, 4 localizzati al tratto medio, 5 al tratto distale e 2 intrasplenici. La diagnosi e stata effettuata con eco color Doppler e/o angio-TC ed e risultata occasionate in 7 pazienti e conseguente a dolore in ipocondrio sinistro in 1 caso; un AAS e stato riscontrato in fase di fissurazione. Quattro AAS sono stati esclusi mediante embolizzazione della sacca con microspirali, con preservazione della continuita dell'asse vascolare; in 2 casi e stata associata l'iniezione transcatetere di cianoacrilato. In 4 casi e stata effettuata una legatura endovascolare, con ischemia settoriaie della milza. Un AAS fisstirato e stato trattato in urgenza con embolizzazione massiva mediante cianoacrilato dell'arteria splenica.

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding. (orig.) [German] Vaskulaere Pathologien sind seltene Ursachen fuer den klinischen Zustand eines akuten Abdomens. Liegt eine vaskulaere Erkrankung vor, ist jedoch aufgrund der hohen Mortalitaet eine zuegige Diagnostik von grosser Wichtigkeit. Bei den Erkrankungen der abdominellen Gefaesse sind arterielle von venoesen Ursachen zu unterscheiden. Ein Verschluss der A. mesenterica superior ist die haeufigste Ursache fuer die akute Mesenterialischaemie, daneben sind Blutungen in den abdominellen Gefaessprovinzen des arteriellen Gefaessbaums von Bedeutung. Venoese Pathologien betreffen thrombotische Verschluesse der Pfortader, der V. mesenterica und der V. cava. Die Multidetektor-CT (MDCT) ist zur Diagnostik vaskulaerer Erkrankungen des Abdominalraums praedestiniert.

Nuestro objetivo fue evaluar la presencia y distribución de placas vulnerables e infiltrados inflamatorios en pacientes fallecidos por infarto agudo de miocardio y su comparación con los hallazgos en pacientes fallecidos por cuadros no coronarios. Se analizaron los estudios anatomopatológicos de corazón de 68 pacientes fallecidos por infarto agudo de miocardio y 15 fallecidos por causa no coronaria. Se registró la presencia de trombo, hemorragia intraplaca, ruptura endotelial e infiltrado inflamatorio. Al evaluar los pacientes fallecidos por IAM, encontramos trombo en 73.5% de las arterias responsables del IAM y en 28.7% de las no responsables (p < 0.0001. La hemorragia intraplaca se halló en el 70.5% de las arterias responsables y en 39.7% de las no responsables, p < 0.0001; ruptura endotelial en el 29.4% de las arterias responsables y en 3.7% de las no responsables, p < 0.0001. No encontramos diferencias en la presencia de infiltrado inflamatorio (76.5% versus 68.4%. Comparando con los fallecidos por causas no coronarias, la presencia de trombo fue significativamente superior (73.5% vs. 13.3%; p < 0.0001, así como la de hemorragia intraplaca (70.5% vs. 0%; p < 0.0001 y de infiltrado inflamatorio en las placas ateroescleroticas (76.5% vs. 46.6%; p = 0.021.

Más recientemente la habilidad para obtener componentes adiposocutáneos similares sin sacrificar el músculo recto ha revolucionado el campo de la Cirugía Reconstructiva. El advenimiento de los colgajos de perforantes ha permitido a los cirujanos plásticos lograr los mismos buenos resultados estéticos que con los colgajos miocutáneos tradicionales, pero con un considerable descenso en la morbilidad del área donante. Con los colgajos de perforantes de la arteria epigástrica inferior profunda (DIEP y de la arteria epigástrica inferior superficial (SIEA, los pacientes han incrementado sus opciones de reconstrucción.

  2. Double elevator weakening for unilateral congenital superior oblique palsy with ipsilateral superior rectus contracture and lax superior oblique tendon.

    Khan, Arif O

    2012-06-01

    In unilateral congenital superior oblique palsy, a large hypertropia is sometimes associated with ipsilateral contracture of the superior rectus muscle and apparent overaction of the contralateral superior oblique. Ipsilateral double elevator weakening is one surgical approach; however, this procedure could compromise supraduction. We report a series of three consecutive patients who underwent ipsilateral superior rectus and inferior oblique recessions for unilateral superior oblique palsy. Intraoperatively, all three patients were found to have a lax ipsilateral superior oblique tendon. Postoperatively, all three patients had satisfactory correction of the hypertropia and abnormal head position with minimal supraduction defect. This procedure seems to be an acceptable initial surgical option for treating congenital superior oblique muscle palsy with ipsilateral contracture of the superior rectus muscle, even when the ipsilateral superior oblique tendon is lax.

    Full Text Available The purpose of this study was to describe arteries supplying the ovaries and uterus in the chinchilla. Five healthy adult female chinchillas were used. In order to reveal the arterial network by dissecting under a stereoscopic microscope, latex coloured with red ink was injected through the common carotid artery. The ovaries of the chinchilla are supplied by the arteriae ovaricae which formed end-to-end anastomoses with the cranial termination of the arteria uterina. Soon after leaving the aorta abdominalis, the arteriae ovaricae extended 2-3mm caudolaterally, then released 1 branch and extended caudally and bifurcated into 2 further branches. One of these supplied branches to fat tissue. The other branch coursed caudally and anastomosed with the arteria circumflexa ilium profunda and dispersed into fat tissue. The arteria ovarica further subdivided into 2 rami ovaricae. The origins of the uterine arteries were exclusively from the left arteria iliaca externa. The arteria uterina gave a branch to the arteria umbilicalis and consecutive branches which supplied to the ureter, urinary bladder and cranial aspects of the vagina. It also gave rise to 2-3 branches to the cervix and further supplied 10-12 meandering branches to the uterine horns. The arteria uterina gave rise to many tortuous arteries to the uterus and provided 2 further branches to the ovary.

    Persistent left superior vena cava absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the coronary sinus. We report the case of a patient with a persistent left superior vena cava and absence of right superior vena cava identified by chance during a chest radiograph and computed tomography examination for investigation of chronic pulmonary obstructive disease. The patient had no congenital heart disease and the blood from the right side was drained by the persistent left superior vena cava into the right atrium through the coronary sinus. (author)

A não-obliteração e regressão da veia cardinal anterior esquerda durante o desenvolvimento embriológico promove uma variação sistêmica de retorno venoso ao coração, com persistência da veia cava superior esquerda. Sua incidência varia de 0,3% em pacientes sem alterações cardíacas congênitas concomitantes a 4,3% naqueles com cardiopatias. Na maioria das vezes coexiste a veia cava superior direita, porém se houver regressão e degeneração da veia cardinal anterior direita, implicará a sua ausência e a drenagem venosa para o coração será feita pela veia cava superior esquerda ao átrio direito, através do seio coronariano. Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avaliação de doença pulmonar obstrutiva crônica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.Persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the

    Full Text Available Abstract Objective: The objective of this study was to determine the incidence of a "meniscoid" superior labrum. Materials and Methods: This was a retrospective analysis of 582 magnetic resonance imaging examinations of shoulders. Of those 582 examinations, 110 were excluded, for a variety of reasons, and the final analysis therefore included 472 cases. Consensus readings were performed by three musculoskeletal radiologists using specific criteria to diagnose meniscoid labra. Results: A meniscoid superior labrum was identified in 48 (10.2% of the 472 cases evaluated. Arthroscopic proof was available in 21 cases (43.8%. In 10 (47.6% of those 21 cases, the operative report did not include the mention a superior labral tear, thus suggesting the presence of a meniscoid labrum. In only one of those cases were there specific comments about a mobile superior labrum (i.e., meniscoid labrum. In the remaining 11 (52.4%, surgical correlation demonstrated superior labral tears. Conclusion: A meniscoid superior labrum is not an infrequent finding. Depending upon assumptions and the requirement of surgical proof, the prevalence of a meniscoid superior labrum in this study was between 2.1% (surgically proven and 4.8% (projected. However, superior labral tears are just as common and are often confused with meniscoid labra.

    A 63 year-old female patient presented herself because of abdominal distension, without being able to report specific complaints. Clinical examination found a well palpable, elastic and engorged abdominal tumour approximately of the size of a football. Conventional imaging of the small intestine according to Sellink with subsequent delayed film revealed in the first instance a displacement of intestinal loops and of the colon frame, with no signs of an onstruction. A similar diagnosis resulted from intraarterial angiography of the abdominal vessels, showing a displacement of the truncus coeliacus, and the A. mesenterica superior. There were no signs of vascular occlusions or pathologic tumour vessels. Surgery revealed a tumour of about 10 kg, with pathologic vascular connection and a broad area of contact to neighbouring intestinal loops. Control CT performed one year after surgery revealed newly developed, multiple, nodular formations, their structure and contrast signs being similar to those of the primary tumour. (orig./VHE) [de

    Full Text Available Los defectos del tercio superior auricular son un desafío reconstructivo. Están descritas diferentes técnicas quirúrgicas para este fin con resultados a veces desfavorables Realizamos un estudio anatómico en cadáveres frescos que mostró la presencia constante de un pedículo neurovascular que penetra la raíz del hélix. Mostramos la localización y los diámetros de los vasos. Basándonos en este estudio anatómico, presentamos una serie de 10 casos consecutivos tratados por el autor principal. Analizamos la etiología, técnica quirúrgica, complicaciones y resultado a largo plazo. La técnica del autor introduce refinamientos a la técnica de Davis, el cual usa un colgajo condrocutáneo de concha auricular basado en la rama superior de la arteria temporal superficial y un colgajo cutáneo axial de base superior basado en la arteria retroauricular, para crear el nuevo hélix auricular superior. El aspecto posterior de este colgajo condrocutáneo se cubre con un injerto de piel total. En un segundo tiempo empleamos una zetaplastia de la base del hélix que nos dará una mejor forma. El estudio anatómico demostró la presencia de un pedículo neurovascular que penetra la raíz del hélix. La serie clínica está compuesta por 8 defectos postraumáticos, una quemadura eléctrica y un tumor de piel. Todos los colgajos condrocutáneos de concha auricular sobrevivieron comprobándose la seguridad del pedículo del hélix. Dos colgajos retroauriculares presentaron sufrimiento vascular transitorio distal, uno de ellos con recuperación completa y otro con necrosis distal mínima. Dos casos sufrieron pérdida parcial del injerto de piel total. Durante el desarrollo de la serie descubrimos algunos detalles de la técnica quirúrgica, que ahora discutimos en el artículo. Todos los pacientes recuperaron el contorno auricular, obteniendo los mejores resultados en aquellos en los que se aplicaron los refinamientos descritos. En conclusión, creemos

    Full Text Available El pseudo-aneurisma de arteria coronaria es extremadamente raro. Su historia natural es poco conocida y su tratamiento discutido. Se presenta el caso de un paciente con pseudo-aneurisma de tronco de la coronaria izquierda e infarto antero-apical del ventrículo izquierdo cinco años después de un paro cardíaco secundario a un traumatismo no penetrante de tórax. Se consideró entonces que la lesión no era pasible de corrección percutánea o quirúrgica por lo que se optó por tratamiento médico conservador. Una angiografía coronaria por tomografía computarizada multicorte realizada 10 años después del evento inicial mostró ausencia de progresión de la lesión.Coronary pseudo-aneurysm is an extremely rare entity. Its natural history is scarcely known and its treatment is controversial. We report a case of pseudo-aneurysm of the left main coronary artery associated with an antero-apical infarct of the left ventricle diagnosed five years after a cardiac arrest following a non-penetrating thoracic trauma. The patient was treated conservatively because percutaneous or surgical correction were not considered suitable for this lesion. A multidetector computed tomography coronary angiogram performed 10 years after the initial event showed no evidence of progression.

    Full Text Available La preservación del nivel de amputación tanto de la extremidad superior como de la inferior, puede mejorar la función residual y el proceso de rehabilitación protésica de la misma. Ambas van a estar condicionadas por la longitud restante de la extremidad, la presencia o no de articulaciones operativas y la calidad de la cobertura del muñón. Presentamos 2 casos de amputaciones. El primero es un caso agudo de amputación traumática de extremidad superior a la altura del tercio proximal de antebrazo, que asocia avulsión cutánea circular desde el tercio medio del brazo y con articulación de codo conservada. El segundo, es la secuela de una amputación infracondílea de extremidad inferior por osteosarcoma que presenta fístulas cutáneas con drenaje supurativo por osteomielitis en el muñón tibial. En ambos pacientes realizamos cobertura con colgajo anterolateral de muslo anastomosado a la arteria radial en el caso de la extremidad superior, y a la arteria genicular descendente en la extremidad inferior. En los dos casos el postoperatorio transcurrió sin complicaciones, logrando preservar las articulaciones del codo y de la rodilla respectivamente, así como la posterior rehabilitación protésica. Consideramos que el colgajo anterolateral del muslo permite aportar tejido de buena calidad como cobertura del muñón de amputación. Dadas las características del tejido aportado y su volumen, es idóneo tanto para cobertura de defectos agudos como de déficits de almohadillado en casos crónicos.

    Full Text Available El aneurisma arterial coronario constituye una entidad rara en la población; su incidencia varía entre 1,5% y 5%, siendo más frecuente en hombres. Existe escasa bibliografía acerca de esta patología a pesar de que su estudio se remonta a finales del siglo XVIII. La arteria que se afecta con mayor frecuencia es la coronaria derecha, aproximadamente en 40% de los casos. La dificultad al momento del diagnóstico clínico radica en que inicialmente el enfoque está dirigido a confirmar y tratar de manera oportuna el síndrome coronario agudo que con insistencia constituye la manifestación inicial con que cursan este tipo de pacientes; por ello el diagnóstico necesariamente requiere ayudas imaginológicas e intervencionistas, o ambas. Hay muchas causas que puedan producir aneurismas en la circulación coronaria, la más común de ellas es la aterosclerosisseguida por trastornos congénitos, enfermedades del tejido conectivo, vasculitis y consumo de cocaína entre otros. Recientemente se han publicado innovadores estudios respecto a la fisiopatología y los avances en terapéutica farmacológica e intervencionista, aunque el tratamiento debe enfocarse en los factores de riesgo, las patologías y las manifestaciones clínicas que presente el paciente.

    Full Text Available A veia cava superior é formada pela união das duas veias inominadas, direita e esquerda, e localiza-se no mediastino médio, à direita da artéria aorta e anteriormente à traquéia. A síndrome da veia cava superior representa um conjunto de sinais (dilatação das veias do pescoço, pletora facial, edema de membros superiores, cianose e sintomas (cefaléia, dispnéia, tosse, edema de membro superior, ortopnéia e disfagia decorrentes da obstrução do fluxo sanguíneo através da veia cava superior em direção ao átrio direito. A obstrução pode ser causada por compressão extrínseca, invasão tumoral, trombose ou por dificuldade do retorno venoso ao coração secundária a doenças intra-atriais ou intraluminais. Aproximadamente 73% a 97% dos casos de síndrome da veia cava superior ocorrem durante a evolução de processos malignos intratorácicos. A maioria dos pacientes com a síndrome secundária a neoplasias malignas é tratada sem necessidade de cirurgia, através de radioterapia ou quimioterapia, ou através da colocação de stents endoluminais. Quando a síndrome é de etiologia benigna, o tratamento é feito através de medidas clínicas (anticoagulação, elevação da cabeça, etc. ou, em casos refratários, através de angioplastia, colocação de stents endoluminais e cirurgia.The superior vena cava is formed by the union of the right and left brachiocephalic veins.

    To compare the efficacy and safety of Ahmed glaucoma valve (AGV) (New World Medical Inc., Rancho Cucamonga, CA) implantation in the superior versus inferior quadrants. Prospective parallel cohort study. A total of 106 eyes of 106 patients with refractory glaucoma. Consecutive patients with refractory glaucoma underwent AGV implantation in the superior or inferior quadrants. Main outcome measures included intraocular pressure (IOP) and rate of complications. Other outcome measures included best corrected visual acuity (BCVA), number of glaucoma medications, and success rate (defined as at least 30% IOP reduction and 5glaucoma surgery, phthisis bulbi, or loss of light perception. Of a total of 106 eyes, 58 and 48 eyes underwent AGV implantation in the superior and inferior quadrants, respectively. Baseline characteristics were comparable in the study groups, except for preoperative IOP, which was higher in the superior group (P = 0.01). Patients were followed for a mean period of 10.6+/-8.49 months and 10.58+/-6.75 months in the superior and inferior groups, respectively (P = 0.477). BCVA was comparable between the groups at all postoperative visits (P>0.122). After 1 year, statistically significant but comparable IOP reduction from baseline (Pglaucoma medications was comparable after 1 year (1.3+/-1.2 vs. 1.9+/-0.8 for superior and inferior implants, respectively, P = 0.256). Success rates were also similar at 1 year: 27 eyes (81.8%) versus 20 eyes (95.2%) for superior and inferior implants, respectively (P = 0.227). However, the overall rate of complications, such as implant exposure necessitating removal, cosmetically unappealing appearance, and endophthalmitis, was higher in the inferior group: 12 eyes (25%) versus 3 eyes (5.2%) for superior and inferior groups, respectively, (P = 0.004). Superior and inferior AGV implants have similar intermediate efficacy in terms of IOP reduction, decrease in number of glaucoma medications, and preservation of vision. However

Operating time as well as per- and post-operative complications were anlyzed. Follow-up was planned following discharge after 1 week, 1 month, 6 months and 1 year. Results: mean operation time was 27 (range 18-43 minutes, and 5 (range 4-7 arteries were located on average. No patient had severe or moderate postoperative pain, with anal discomfort being the main complaint. Rectal bleeding and tenesmus were the commonest post-operative complications. After one year of follow-up, 19 patients were free of symptoms and 6 of them had significant symptom relief. According to grade, the technique failed in just 3 grade III patients, but in as many as 4 grade IV hemorrhoid cases. Conclusions: doppler-guided hemorrhoid artery ligation is an easy-to-perform technique that is well accepted by patients and has good results for grade III hemorrhoids.Objetivo: el objetivo de este trabajo es valorar en la clínica la eficacia de una nueva técnica quirúrgica para el tratamiento de las hemorroides de grado III y IV.

    2008-01-01

    Full Text Available The prosopomorphic vessels from Moesia Superior had the form of beakers varying in outline but similar in size. They were wheel-thrown, mould-made or manufactured by using a combination of wheel-throwing and mould-made appliqués. Given that face vessels are considerably scarcer than other kinds of pottery, more than fifty finds from Moesia Superior make an enviable collection. In this and other provinces face vessels have been recovered from military camps, civilian settlements and necropolises, which suggests that they served more than one purpose. It is generally accepted that the faces-masks gave a protective role to the vessels, be it to protect the deceased or the family, their house and possessions. More than forty of all known finds from Moesia Superior come from Viminacium, a half of that number from necropolises. Although tangible evidence is lacking, there must have been several local workshops producing face vessels. The number and technological characteristics of the discovered vessels suggest that one of the workshops is likely to have been at Viminacium, an important pottery-making centre in the second and third centuries.

    Liu, Z.; Bi, W.; Li, J.; Li, Q.; Dong, C.; Zhao, P.; Lv, H.; Wang, Z.

    2015-01-01

    Aim: To examine the association between superior semicircular canal dehiscence (SSCD) and pulsatile tinnitus (PT). Materials and methods: Two SSCD groups included 408 unilateral persistent PT patients, and 511 controls undergoing head and neck dual-phase contrast-enhanced computed tomography (DP-CECT) for reasons other than PT. The prevalence of type I (no the superior petrosal sinus running through the dehiscence) and type II (superior semicircular canal dehiscence in relation to the superior petrosal sinus) SSCD was analysed using chi-square test. Results: SSCD was identified in 5.1% (21/408) of PT ears, significantly different from 2% (8/408) of non-PT ears and 0.7% (7/1022) of controls. There was no significant difference in SSCD prevalence between non-PT ears in the PT group and controls. In the PT group, 15/21 ears were type II SSCD; 6/21 ears were type I. Fifteen combined non-PT and control ears with SSCD included two type II and 13 type I SSCD. The prevalence of type II SSCD in PT ears was significantly higher than that of non-PT ears in both groups, and the prevalence of type I SSCD in PT ears was similar to that of non-PT ears in both groups. Conclusion: Compared with type I SSCD, there may be a causal relationship between type II SSCD and PT. -- Highlights: •The prevalence of type II SSCD in PT ears was significantly higher than that in non-PT ears in both the PT group and controls. •The prevalence of type I SSCD was similar among the PT ears and non-PT ears. •The superior petrosal sinus running through the dehiscence may be essential for SSCD to induce PT. •Venous phase CT images with bone window settings is the modality method to differentiate type II from type I SSCD

Relatamos o caso de uma paciente, na qual durante implante de marca-passo definitivo, para a correção de bloqueio atrioventricular total, foi detectada presença de veia cava superior esquerda com suspeição de ausência de veia cava superior, o que levou ao emprego de técnica diferenciada para fixação do eletrodo ventricular. Para confirmação da provável agenesia, foram realizados diversos exames complementares de imagem, demonstrando-se a dificuldade no diagnóstico da síndrome aqui descrita.The superior left vena cava with the absent superior vena cava is a rare abnormality, especially when associated with total heart block. We report a case of a patient in which the presence of superior left vena cava and the absence of the superior vena cava was detected during the implantation of a pacemaker for the correction of a total heart block, which led us to use a different technique for the fixation of the ventricular electrode. To confirm the supposed absence, several image exams were made showing the difficulty on the diagnosis of the described syndrome.

  4. Writing superiority in cued recall

    Full Text Available In list learning paradigms with free recall, written recall has been found to be less susceptible to intrusions of related concepts than spoken recall when the list items had been visually presented. This effect has been ascribed to the use of stored orthographic representations from the study phase during written recall (Kellogg, 2001. In other memory retrieval paradigms, either better recall for modality-congruent items or an input-independent writing superiority effect have been found (Grabowski, 2005. In a series of four experiments using a paired associate (PA learning paradigm we tested (a whether output modality effects on verbal recall can be replicated in a paradigm that does not involve the rejection of semantically related intrusion words, (b whether a possible superiority for written recall was due to a slower response onset for writing as compared to speaking in immediate recall, and (c whether the performance in PA word recall was correlated with performance in an additional episodic memory task. We found better written recall in the first half of the recall phase, irrespective of the modality in which the material was presented upon encoding. An explanation based on longer response latencies for writing and hence more time for retrieval could be ruled out by showing that the effect persisted in delayed response versions of the task. Although there was some evidence that stored additional episodic information may contribute to the successful retrieval of associate words, this evidence was only found in the immediate response experiments and hence is most likely independent from the observed output modality effect. In sum, our results from a PA learning paradigm suggest that superior performance for written versus spoken recall cannot be (solely explained in terms of additional access to stored orthographic representations from the encoding phase. Our findings rather suggest a general writing-superiority effect at the time of memory

    1985-01-01

    Sciatica caused by root entrapment in the lateral recess was named superior facet syndrome by Epstein in 1972. Few reports on this subject based on large numbers of cases have been documented to date. Of the patients with sciatica, 32 patients were diagnosed to have root entrapment at the lateral recess L 5 or/and S 1 lumbar spine. Out of 32 patients, 20 patients were operated on and the lateral entrapment was recognized in all of surgical cases. Neuroradiological findings, especially of metrizamide CT (met. CT), were documented in detail. Thirty two patients were classified in three types according to radiological findings. They were congenital or developmental, degenerative, and combined type, respectively, Fourteen cases belonged to the congenital type, 13 to the degenerative and 5 to the combined type. Each group had the mean ages of 23.4, 53.8, and 36.8 years old, respectively. Of 32 cases the entrapment occured in 47 L 5 roots and 11 S 1 roots. There was no remarkable laterality. In operation the unroofing of the lateral recess were done and the sciatica subsided postoperatively in all of surgical cases. Met. CT revealed extreme medial protrusion of the superior articular joint in 18 of 24 cases(75%) and none filling of the root in the lateral recess in 21 of 24 cases (87.5%). In the degenerative type, met. CT showed some degenerative changes that were hypertrophy or deformity of the articular joints and spur formation of the vertebral body. In contrast to met. CT, metrizamide myelography revealed only slight changes, which were poor filling of the root before it turned out the pedicle of lateral compression of the root. In plain films or lumbar spine articular joints at Lsub(4/5) were formed in coronal plane in 69% of cases of the L 5 root entrapment. Met. CT using ReView technique was of great diagnostic value in superior facet syndrome. (author)

    We wanted to determine the mechanisms of motor vertical fusion in patients with superior oblique paresis and to correlate these mechanisms with surgical outcomes. Ten patients with superior oblique paresis underwent 3-axis, bilateral, scleral search coil eye movement recordings. Eye movements associated with fusion were analyzed. Six patients had decompensated congenital superior oblique paresis and 4 had acquired superior oblique paresis. All patients with acquired superior oblique paresis relied predominantly on the vertical rectus muscles for motor fusion. Patients with congenital superior oblique paresis were less uniform in their mechanisms for motor fusion: 2 patients used predominantly the oblique muscles, 2 patients used predominantly the vertical recti, and 2 patients used predominantly the superior oblique in the hyperdeviated eye and the superior rectus in the hypodeviated eye. The last 2 patients developed the largest changes in torsional eye alignment relative to changes in vertical eye alignment and were the only patients to develop symptomatic surgical overcorrections. There are 3 different mechanisms for vertical fusion in individuals with superior oblique paresis, with the predominant mechanism being the vertical recti. A subset of patients with superior oblique paresis uses predominantly the superior oblique muscle in the hyperdeviated paretic eye and the superior rectus muscle in the fellow eye for fusion. This results in intorsion of both eyes, causing a large change in torsional alignment. The consequent cyclodisparity, in addition to the existing vertical deviation, may make fusion difficult. The differing patterns of vertical fusional vergence may have implications for surgical treatment.

    The field marketing practices of Superior Propane in rural Ontario are illustrated. In the Smithville area, Superior's customer base consists of agricultural, industrial, commercial, and residential customers, plus a large market for auto propane. A 6,900 ft 2 showroom presents a representative selection of the wide range of appliances using propane. Superior's Smithville branch is one of the top five in Canada, in terms of volume. To expand business beyond its traditional branch structures, Superior has an Independent Partners Program which is aimed at all phases of business including independent sales agents, conversions, propane fuel stops, appliance installations, and building contractors. In Keswick, located in the summer resort region on the south shore of Lake Simcoe, Superior's base load is 40% commercial and 20% each agricultural, residential, and automotive. A new 4,100 ft 2 showroom was recently constructed with separate display units for each appliance. The new building has brought increases in auto propane and appliance sales. The different branches of Superior Propane are able to tailor their marketing programs according to local needs by choosing the appropriate programs from those available at head office. 5 figs

    Full Text Available Data suggests that individuals with schizophrenia (SZ and superior intelligence can present without specific neurocognitive deficits. However, neurocognitive decrements, defined as worse cognition than expected, have been reported in practically all schizophrenia cases. This study investigated if neurocognitive decrements are present in intellectually superior SZ by comparing the neuropsychological profile of SZ cases with IQ-matched healthy controls (HC across intellectual level. Participants with SZ and HCs were stratified into three IQ-groups; intellectually low (IQ 80-95; SZ n = 65 & HC n = 13, intellectually normal (IQ = 100-115; SZ n = 111 & HC n = 115 and intellectually superior (IQ > 120; SZ n = 20 & HC n = 50. A repeated measures multivariate analysis of co-variance compared performance on eight selected neuropsychological tests across IQ-strata and diagnostic group. Differences in clinical characteristics and social functioning in SZ across IQ-strata were investigated with multivariate and univariate analyses of variance. Intellectually superior SZ participants scored within normal limits, but had neurocognitive decrements compared to superior HCs. Decrements were of the same magnitude as in the low and normal IQ-strata. Levels of functional impairments and clinical characteristics in participants with SZ did not differ significantly across IQ-strata. Results indicate that neurocognitive decrements are present in intellectually superior SZ to the same extent as in intellectually low and intellectually normal SZ, supporting the notion that SZ is a neurocognitive disorder. Similar levels of social functional deficits and clinical symptoms suggest similar disease processes in SZ across intellectual level.

    Managers influence the way organization works as well as the functioning of subordinates - in the context of their work life but non-professional functioning as well e.g., attitude towards work-life balance or taking care of health. We focused on the superior-subordinate relation, referring to social power bases theory by Raven. We identified the reasons why subordinates decide to follow their superiors' orders and determined specific styles of compliance with superiors' will. Understanding why employees listen to their superiors may be valuable in the context of supporting healthy organizational climate and atmosphere of co-operation or communicating values - for example, as regards taking care of own health. We discussed the results referring to the issue of influencing employees in the context of their health behavior. The research involved 100 Polish employees, aged 28 years old on average, who filled in the Interpersonal Power Inventory by Raven et al. for subordinates in a Polish adaptation by Zaleski. The questionnaire includes 11 subscales referring to power bases. Based on the cluster analysis results, we recognized people who complied because of: all kinds of power bases (typical for 46% of the respondents); the respect for superiors' professionalism (34%); and formal/objective reasons (20%). Employees differ in terms of their styles of compliance. Their motives to comply with superiors' instructions constitute compilations of power bases. The superiors' awareness of the reasons why their employees decide to follow orders is necessary for successful management. It may motivate employees to work but also to take care of their own health. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

  13. Perturbation resilience and superiorization of iterative algorithms

    International Nuclear Information System (INIS)

    Censor, Y; Davidi, R; Herman, G T

    2010-01-01

    Iterative algorithms aimed at solving some problems are discussed. For certain problems, such as finding a common point in the intersection of a finite number of convex sets, there often exist iterative algorithms that impose very little demand on computer resources. For other problems, such as finding that point in the intersection at which the value of a given function is optimal, algorithms tend to need more computer memory and longer execution time. A methodology is presented whose aim is to produce automatically for an iterative algorithm of the first kind a 'superiorized version' of it that retains its computational efficiency but nevertheless goes a long way toward solving an optimization problem. This is possible to do if the original algorithm is 'perturbation resilient', which is shown to be the case for various projection algorithms for solving the consistent convex feasibility problem. The superiorized versions of such algorithms use perturbations that steer the process in the direction of a superior feasible point, which is not necessarily optimal, with respect to the given function. After presenting these intuitive ideas in a precise mathematical form, they are illustrated in image reconstruction from projections for two different projection algorithms superiorized for the function whose value is the total variation of the image

    Directory of Open Access Journals (Sweden)

    Metin Keskin

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

  18. [Neuromolecular mechanism of the superiority illusion].

    Science.gov (United States)

    Yamada, Makiko

    2014-01-01

    The majority of individuals evaluate themselves as above average. This is a cognitive bias called "the superiority illusion". This illusory self-evaluation helps us to have hopes for the future, and has been central to the process of human evolution. Possessing this illusion is also important for mental health, as depressed people appear to have a more realistic perception of themselves, dubbed "depressive realism". Our recent study revealed the spontaneous brain activity and central dopaminergic neurotransmission that generate this illusion, using resting-state fMRI and PET. A functional connectivity between the frontal cortex and striatum, regulated by inhibitory dopaminergic neurotransmission, determines individual levels of the superiority illusion. We further revealed that blocking the dopamine transporter, which enhanced the level of dopamine, increased the degree of the superiority illusion. These findings suggest that dopamine acts on striatal dopamine receptors to suppress fronto-striatal functional connectivity, leading to disinhibited, heuristic, approaches to positive self-evaluation. These findings help us to understand how this key aspect of the human mind is biologically determined, and will suggest treatments for depressive symptoms by targeting specific molecules and neural circuits.

    Acromioplasty is increasingly being performed for both reparable and irreparable rotator cuff tears. However, acromioplasty may destroy the coracoacromial arch, including the coracoacromial ligament, consequently causing a deterioration in superior stability even after superior capsule reconstruction. The purpose of this study was to investigate the effects of acromioplasty on shoulder biomechanics after superior capsule reconstruction for irreparable supraspinatus tendon tears. The hypothesis was that acromioplasty with superior capsule reconstruction would decrease the area of subacromial impingement without increasing superior translation and subacromial contact pressure. Controlled laboratory study. Seven fresh-frozen cadaveric shoulders were evaluated using a custom shoulder testing system. Glenohumeral superior translation, the location of the humeral head relative to the glenoid, and subacromial contact pressure and area were compared among 4 conditions: (1) intact shoulder, (2) irreparable supraspinatus tendon tear, (3) superior capsule reconstruction without acromioplasty, and (4) superior capsule reconstruction with acromioplasty. Superior capsule reconstruction was performed using the fascia lata. Compared with the intact shoulder, the creation of an irreparable supraspinatus tear significantly shifted the humeral head superiorly in the balanced muscle loading condition (without superior force applied) (0° of abduction: 2.8-mm superior shift [P = .0005]; 30° of abduction: 1.9-mm superior shift [P = .003]) and increased both superior translation (0° of abduction: 239% of intact [P = .04]; 30° of abduction: 199% of intact [P = .02]) and subacromial peak contact pressure (0° of abduction: 308% of intact [P = .0002]; 30° of abduction: 252% of intact [P = .001]) by applying superior force. Superior capsule reconstruction without acromioplasty significantly decreased superior translation (0° of abduction: 86% of intact [P = .02]; 30° of abduction: 75

  1. The picture superiority effect in associative recognition.

    Hockley, William E

    2008-10-01

    The picture superiority effect has been well documented in tests of item recognition and recall. The present study shows that the picture superiority effect extends to associative recognition. In three experiments, students studied lists consisting of random pairs of concrete words and pairs of line drawings; then they discriminated between intact (old) and rearranged (new) pairs of words and pictures at test. The discrimination advantage for pictures over words was seen in a greater hit rate for intact picture pairs, but there was no difference in the false alarm rates for the two types of stimuli. That is, there was no mirror effect. The same pattern of results was found when the test pairs consisted of the verbal labels of the pictures shown at study (Experiment 4), indicating that the hit rate advantage for picture pairs represents an encoding benefit. The results have implications for theories of the picture superiority effect and models of associative recognition.

    It has been suggested that neurocognitive impairment is a core deficit in schizophrenia. However, it appears that some patients with schizophrenia have intelligence quotients (IQs) in the superior range. In this study, we sought out schizophrenia patients with an estimated premorbid Intelligence Quotient (IQ) of at least 115 and studied their neuropsychological profile. Thirty-four patients meeting diagnostic criteria for schizophrenia or schizoaffective disorder, as defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV), with mean estimated premorbid IQ of 120, were recruited and divided into two subgroups, according to whether or not their IQ had declined by at least 10 points from their premorbid estimate. Their performance on an extensive neuropsychological battery was compared with that of 19 IQ-matched healthy controls and a group of 16 "typical" schizophrenia patients with estimated premorbid IQ Schizophrenia patients whose estimated premorbid and current IQ both lay in the superior range were statistically indistinguishable from IQ-matched healthy controls on all neurocognitive tests. However, their profile of relative performance in subtests was similar to that of typical schizophrenia patients. Patients with superior premorbid IQ and evidence of intellectual deterioration had intermediate scores. Our results confirm the existence of patients meeting DSM-IV diagnostic criteria for schizophrenia who have markedly superior premorbid intellectual level and appear to be free of gross neuropsychological deficits. We discuss the implications of these findings for the primacy of cognitive deficits in schizophrenia.

    The right superior vena cava draining into the left atrium is a rare malformation causing cyanosis and clubbing in patients in whom no other signs of congenital heart defect are present. Diagnosis may be difficult as cyanosis may be mild and the anomaly is not always easily detectable by echocardiography. For this reason we report a 13-month-old male in whom we confirmed the clinical and echocardiographic suspicion of anomalous drainage of the right superior vena cava using multidetector CT. This allowed successful surgical reconnection of the right superior vena cava to the right atrium. (orig.)

  5. Eutrophication monitoring for Lake Superior's Chequamegon ...

    Science.gov (United States)

    A priority for the Lake Superior CSMI was to identify susceptible nearshore eutrophication areas. We developed an integrated sampling design to collect baseline data for Lake Superior’s Chequamegon Bay to understand how nearshore physical processes and tributary loading relate to observed chlorophyll concentrations. Sampling included ship-based water samples combined with vertical CTD casts, continuous in situ towing and data collected from an autonomous underwater glider. Sampling was conducted during June, July and September. The glider collected regional data as part of three extended missions in Lake Superior over the same periods. During the study, two significant storm events impacted the western end of Lake Superior; the first occurred during July 11-12, with 8-10 inches of rain in 24hrs, and the second on July 21 with winds in excess of 161 km/h. Using GIS software, we organized these diverse temporal data sets along a continuous time line with temporally coincident Modis Satellite data to visualize surface sediment plumes in relation to water quality measurements. Preliminary results suggest that both events impacted regional water quality, and that nearshore physical forces (upwelling and currents) influenced the spatial variability. Results comparing in situ measures with remotely sensed images will be discussed. not applicable

    2017-04-01

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

  11. Aneurysm of the superior mesenteric artery

    This is a report about 4 patients with aneurysms of the superior mesenteric artery of arteriosclerotic, mycotic and probably congenital etiology together with a review of the literature as to the etiology, diagnostic possibilities and therapy. Arteriography is the method of choice even though a diagnosis may be possible by sonography or CT in special cases. Even though an aneurysm of the superior mesenteric artery is rare, it has to be considered in the differential diagnosis of persisting abdominal problems of unknown origin. This is especially true for patients with a predisposing history such as previous or existing endocarditis, sepsis, arteriosclerosis and hypertension. Because of the possibility of rupture followed by life threating bleeding an adequate diagnostic step such as arteriography has to be considered finally.

    2011-12-01

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior.

    Winograd, E; Smith, A D; Simon, E W

    1982-01-01

    One recurrent theme in the literature on aging and memory is that the decline of memory for nonverbal information is steeper than for verbal information. This research compares verbal and visual encoding using the picture superiority effect, the finding that pictures are remembered better than words. In the first experiment, an interaction was found between age and type of material; younger subjects recalled more pictures than words while older subjects did not. However, the overall effect was small and two further experiments were conducted. In both of these experiments, the picture superiority effect was found in both age groups with no interaction. In addition, performing a semantic orienting task had no effect on recall. The finding of a picture superiority effect in older subjects indicates that nonverbal codes can be effectively used by subjects in all age groups to facilitate memory performance.

    Aim: To demonstrate changes in gastric mucosal blood flow caused by intraoperative radiotherapy of the celiac artery combined with external radiotherapy of the upper abdomen in a rabbit model. The study was designed to identify a possible correlation between a radiation-induced reduction in mucosal blood flow and the induction of gastric ulcer. Material and Method: Intraoperative radiation doses of 0 or 30 Gy were given to the celiac artery in rabbits. After a delay of 14 days external radiotherapy of the upper abdomen with 3x4 Gy/week to a maximum total dose of 40 Gy was initiated. Gastric mucosal blood flow was assessed by intraventricular injection of radioactively-labelled microspheres (15 {mu}m) followed by measurement of radioactivity in the mucosa. The injections were performed at various time intervals between 2 and 63 days after intraoperative radiation. Results: Intraoperative radiotherapy, including sham-intraoperative radiation, resulted in a transitory reduction of mucosal blood flow by about 50% of the control value on day 7. After a temporary recovery by day 14, a marked and permanent reduction in blood flow was assessed after week 6. This time corresponds to the time of development of gastric ulcer. Conclusions: A relationship between the time of ulcer development and of reduced gastric mucosal blood flow was observed after combined intraoperative and external radiotherapy. The mechanical component of intraoperative treatment has to be emphasized. Reduced blood flow was also seen after intraoperative radiotherapy alone, without an induction of ulcer by this treatment. Hence additional mucosal damage by external radiation must be present for the induction of gastric ulcer. (orig.)

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority.This article is part of the themed issue 'Quantum technology for the 21st century'. © 2017 The Author(s).

    The superior temporal gyrus has been implicated in language processing and social perception. Therefore, anatomical abnormalities of this structure may underlie some of the deficits observed in autism, a severe neurodevelopmental disorder characterized by impairments in social interaction and communication. In this study, volumes of the left and right superior temporal gyri were measured using magnetic resonance imaging obtained from 18 boys with high-functioning autism (mean age=13.5±3.4years; full-scale IQ=103.6±13.4) and 19 healthy controls (mean age=13.7±3.0years; full-scale IQ=103.9±10.5), group-matched on age, gender, and handedness. When compared to the control group, right superior temporal gyral volumes was significantly increased in the autism group after controlling for age and total brain volume. There was no significant difference in the volume of the left superior temporal gyrus. Post-hoc analysis revealed a significant increase of the right posterior superior temporal gyral volume in the autism group, before and after controlling for age and total brain volume. Examination of the symmetry index for the superior temporal gyral volumes did not yield statistically significant between-group differences. Findings from this preliminary investigation suggest the existence of volumetric alterations in the right superior temporal gyrus in children and adolescents with autism, providing support for a neuroanatomical basis of the social perceptual deficits characterizing this severe neurodevelopmental disorder.

    Over the last 5 years, refining companies have not performed well financially, generating returns below the cost of capital. Environmental regulations have caused the industry to invest significant amounts of capital, and while new regulations will cause the shutdown of between 500 thousand and 1.2 million barrels per day of capacity, the industry structure will remain poor and financial returns for the average player will likely be volatile, cyclical, and below the cost of capital. Based on this industry outlook, refining companies seeking superior performance will have to break the traditional paradigms and adopt world-class practices used in other industries. Changes required to significantly improve financial returns will include shifts in business strategy to accommodate growth, and development of nontraditional services, as well as initiates to dramatically reshape cost structure and improve profitability. Making the changes to become a superior performer in the refining business will require a clear vision and strong leadership at multiple levels in the organization. The transformation will also require changes in company culture and incentive plans that encourage managers to act as owners. In addition, superior performers will push accountability for results to low levels in the organization.

    To conduct radiologic anatomical study on the relation between S1 sacroiliac screws' entry points and the route of the pelvic outer superior gluteal artery branches with the aim to provide the anatomical basis and technical reference for the avoidance of damage to the superior gluteal artery during the horizontal sacroiliac screw placement. Superior gluteal artery CTA (CT angiography) vascular imaging of 74 healthy adults (37 women and 37 men) was done with 128-slice spiral CT (computed tomography). The CT attendant-measuring software was used to portray the "safe bony entrance area" (hereinafter referred to as "Safe Area") of the S1 segment in the standard lateral pelvic view of three-dimensional reconstruction. The anatomical relation between S1 sacroiliac screws' Safe Area and the pelvic outer superior gluteal artery branches was observed and recorded. The number of cases in which artery branches intersected the Safe Area was counted. The cases in which superior gluteal artery branches disjointed from the Safe Area were identified, and the shortest distance between the Safe Area and the superior gluteal artery branch closest to the Safe Area was measured. Three cases out of the 74 sample cases were excluded from this study as they were found to have no bony space for horizontal screw placement in S1 segment. Among the remaining 71 sample cases, there are 32 cases (45.1%) where the deep superior branch of superior gluteal artery passes through the Safe Area of S1 entrance point. There was no distinguishing feature and rule on how the deep superior branches and the Safe Area overlapped. In the 39 cases in which superior gluteal artery branches disjointed from the Safe Area, the deep superior branches of superior gluteal artery were the branches closest to the Safe Area and the part of the branch closest to the Safe Area was located in front of the widest part of the Safe Area. The shortest distance between the deep superior branch and the Safe Area is 0.86

    We report the first observation of clinical manifestations of vena cava superior syndrome (VCSS) associated with sarcoidosis. Twenty-four years after the first signs of the disease had been noted, mediastinal lymphomas penetrating the wall of the vena cava superior caused complete obstruction. It is most unusual for the vessel wall to be destroyed in this way, which explains why VCSS is often missed in sarcoidosis. The obstructed vessel was resected and successfully replaced by a Gore-Tex prosthesis. The importance of VCSS for the differential diagnosis is pointed out. Two further peculiarities are the simultaneous occurrence of elevated intraocular pressure and VCSS, and the familial incidence. (orig.) [de

These options are simple and practical, and make minimal information demands.

    2014-01-01

    Full Text Available Importance. Superior semicircular canal dehiscence (SCD is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A “two-hit” hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head injury, no previous reports have described a temporal bone fracture directly causing SCD. Observations. Two patients sustained temporal bone fractures after closed head trauma, and developed unilateral otologic symptoms consistent with SCD. In each instance, computed tomography imaging revealed fractures extending through the bony roof of the superior semicircular canal. Conclusions and Relevance. Temporal bone fractures, which are largely treated nonoperatively, have not previously been reported to cause SCD. As it is a potentially treatable entity, SCD resulting from temporal bone fracture must be recognized as a possibility and diagnosed promptly if present.

    Musicians' perceptual advantage in the acoustic domain is well established. Recent studies show that musicians' verbal working memory is also superior. Additionally, some studies report that musicians' visuospatial skills are enhanced although others failed to find this enhancement. We now examined whether musicians' spatial vision is superior, and if so, whether this superiority reflects refined visual skills or a general superiority of working memory. We examined spatial frequency discrimination among musicians and nonmusician university students using two presentation conditions: simultaneous (spatial forced choice) and sequential (temporal forced choice). Musicians' performance was similar to that of nonmusicians in the simultaneous condition. However, their performance in the sequential condition was superior, suggesting an advantage only when stimuli need to be retained, i.e., working memory. Moreover, the two groups showed a different pattern of correlations: Musicians' visual thresholds were correlated, and neither was correlated with their verbal memory. By contrast, among nonmusicians, the visual thresholds were not correlated, but sequential thresholds were correlated with verbal memory scores, suggesting that a general working memory component limits their performance in this condition. We propose that musicians' superiority in spatial frequency discrimination reflects an advantage in a domain-general aspect of working memory rather than a general enhancement in spatial-visual skills. © 2014 ARVO.

  11. Ruptured superior gluteal artery pseudoaneurysm with hemorrhagic shock: Case report

    Directory of Open Access Journals (Sweden)

    Kerem Seref Corbacioglu

    2016-03-01

    Full Text Available Pseudoaneurysm of the superior gluteal artery (SGA is very rare and the most common causes are blunt or penetrating pelvic traumas. Although pseudoaneurysm can be asymptomatic at the time of initial trauma, it can be symptomatic weeks, months, even years after initial trauma. We present a case of a ruptured superior gluteal artery pseudoaneurysm with hemorrhagic shock twenty days after a bomb injury in the Syria civil war. In addition, we review the anatomy of the SGA, clinical presentation and pitfalls of pseudoaneurysm, and imaging and treatment options.

  13. Total variation superiorized conjugate gradient method for image reconstruction

    The conjugate gradient (CG) method is commonly used for the relatively-rapid solution of least squares problems. In image reconstruction, the problem can be ill-posed and also contaminated by noise; due to this, approaches such as regularization should be utilized. Total variation (TV) is a useful regularization penalty, frequently utilized in image reconstruction for generating images with sharp edges. When a non-quadratic norm is selected for regularization, as is the case for TV, then it is no longer possible to use CG. Non-linear CG is an alternative, but it does not share the efficiency that CG shows with least squares and methods such as fast iterative shrinkage-thresholding algorithms (FISTA) are preferred for problems with TV norm. A different approach to including prior information is superiorization. In this paper it is shown that the conjugate gradient method can be superiorized. Five different CG variants are proposed, including preconditioned CG. The CG methods superiorized by the total variation norm are presented and their performance in image reconstruction is demonstrated. It is illustrated that some of the proposed variants of the superiorized CG method can produce reconstructions of superior quality to those produced by FISTA and in less computational time, due to the speed of the original CG for least squares problems. In the Appendix we examine the behavior of one of the superiorized CG methods (we call it S-CG); one of its input parameters is a positive number ɛ. It is proved that, for any given ɛ that is greater than the half-squared-residual for the least squares solution, S-CG terminates in a finite number of steps with an output for which the half-squared-residual is less than or equal to ɛ. Importantly, it is also the case that the output will have a lower value of TV than what would be provided by unsuperiorized CG for the same value ɛ of the half-squared residual.

  14. The Penokean orogeny in the Lake Superior region

    Science.gov (United States)

    Schulz, K.J.; Cannon, W.F.

    2007-01-01

    The Penokean orogeny began at about 1880 Ma when an oceanic arc, now the Pembine-Wausau terrane, collided with the southern margin of the Archean Superior craton marking the end of a period of south-directed subduction. The docking of the buoyant craton to the arc resulted in a subduction jump to the south and development of back-arc extension both in the initial arc and adjacent craton margin to the north. A belt of volcanogenic massive sulfide deposits formed in the extending back-arc rift within the arc. Synchronous extension and subsidence of the Superior craton resulted in a broad shallow sea characterized by volcanic grabens (Menominee Group in northern Michigan). The classic Lake Superior banded iron-formations, including those in the Marquette, Gogebic, Mesabi and Gunflint Iron Ranges, formed in that sea. The newly established subduction zone caused continued arc volcanism until about 1850 Ma when a fragment of Archean crust, now the basement of the Marshfield terrane, arrived at the subduction zone. The convergence of Archean blocks of the Superior and Marshfield cratons resulted in the major contractional phase of the Penokean orogeny. Rocks of the Pembine-Wausau arc were thrust northward onto the Superior craton causing subsidence of a foreland basin in which sedimentation began at about 1850 Ma in the south (Baraga Group rocks) and 1835 Ma in the north (Rove and Virginia Formations). A thick succession of arc-derived turbidites constitutes most of the foreland basin-fill along with lesser volcanic rocks. In the southern fold and thrust belt tectonic thickening resulted in high-grade metamorphism of the sediments by 1830 Ma. At this same time, a suite of post-tectonic plutons intruded the deformed sedimentary sequence and accreted arc terranes marking the end of the Penokean orogeny. The Penokean orogen was strongly overprinted by younger tectonic and thermal events, some of which were previously ascribed to the Penokean. Principal among these was a

  16. Sedimentation rates and depositional processes in Lake Superior from 210Pb geochronology

    International Nuclear Information System (INIS)

    Evans, J.E.; Johnson, T.C.; Alexander, E.C. Jr.; Lively, R.S.; Eisenreich, S.J.

    1981-01-01

    Sedimentation rates range from 0.01 to 0.32 cm/yr in 17 sediment box cores from Lake Superior, as determined by 210 Pb geochronology. Shoreline erosion and resuspension of nearshore sediments causes moderate to high (0.05-0.11 cm/yr) sedimentation rates in the western arm of Lake Superior. Sedimentation rates are very high (> 0.15 cm/yr) in marginal bays adjoining Lake Superior; and moderate to very high (0.07-0.19 cm/yr) in open lake regions adjacent to marginal bays. Resuspension of nearshore and shoal top sediments in southern and southeastern Lake Superior by storms is responsible for depositional anomalies in 210 Pb profiles corresponding to 1905, 1916-1918, and 1940 storms. Sedimentation rates are very low (0.01-0.03 cm/yr) in the central basins due to isolation from sediment sources. These data indicate that sedimentation rates and processes vary significantly in different regions of Lake Superior. The sedimentation rates provided by this study, in conjunction with previously-reported sedimentation rates, yield a better understanding of the Lake Superior depositional environment

  8. Waldenstrom macroglobulinemia involving the superior rectus muscle

    Directory of Open Access Journals (Sweden)

    J.B. Hellman

    2018-06-01

    Full Text Available Purpose: We present the first reported case of Waldenstrom macroglobulinemia in the right superior rectus causing diplopia. Observations: A 72-year-old man with a 6-month history of untreated asymptomatic Waldenstrom macroglobulinemia presented with 2 years of diagonal binocular diplopia that was previously thought to be due to ocular myasthenia gravis. Examination showed mild right proptosis and right hypotropia, and MRI revealed a focal lesion of the right superior rectus muscle. Orbital biopsy was performed, and histopathology showed lymphoplasmacytic infiltration among the skeletal muscle fibers of the rectus muscle. Immunostaining confirmed a B-cell preponderance, along with more extensive staining for IgM than IgG, and in situ hybridization confirmed lambda restriction. These findings corresponded with those of his previous bone marrow biopsy, confirming Waldenstrom macroglobulinemia as the etiology for the extraocular muscle mass. Conclusions and Importance: Lymphoma of an extraocular muscle is a rare manifestation of orbital lymphoma, and the tumors are usually mucosa-associated lymphoid tissue (MALT lymphomas (i.e. extranodal marginal zone lymphomas. There are 4 previous reports of lymphoplasmacytic lymphoma of an extraocular muscle; however this is the first reported case of such a lesion in a patient with concurrent Waldenstrom macroglobulinemia at the time of diagnosis.

    Superior semicircular canal dehiscence is a newly described syndrome of sound and/or pressure induced vertigo. Computed tomography (CT) imaging plays an important role in confirmation of a defect in the bone overlying the canal. A high resolution CT technique utilising 0.5 mm or thinner slices and multi-planar reconstructions parallel to the superior semicircular canal is required. Placement of a histogram over a suspected defect can assist CT diagnosis

Nietzsche's superior man (educated and cultivated man is that one, in which there is harmony in the drives, who can give greater freedom to its most terrible drives, without, however, loses the control over them. That is the contradiction: if man has to control the drives, they are not harmonics. There is incompatibility between harmony and control. In other words, the superior man is indeed the man of culture and cultivated man of Nietzsche? If the answer to this question is yes, then, in this man, reigns the drives harmony. If, on the other hand, the answer is no, then, for this man does not become a barbarian destroyer, dangerous to himself and to others it is necessary that a drive dominates the others. However it is not possible to escape the contradiction: either there is harmony in human drive or control.Este artigo busca resolver a seguinte contradição do pensamento de Nietzsche: o homem possui uma constituição subjetiva pulsional, estas pulsões, porém, são individuais, e o seu ser, o das pulsões, constitui-se da luta por mais poder (vontade de poder.

    It is well established that multisensory integration is a functional characteristic of the superior colliculus that disambiguates external stimuli and therefore reduces the reaction times toward simple audiovisual targets in space. However, in a condition where a complex audiovisual stimulus is used, such as the optical flow in the presence of modulated audio signals, little is known about the processing of the multisensory integration in the superior colliculus. Furthermore, since visual and auditory deficits constitute hallmark signs during aging, we sought to gain some insight on whether audiovisual processes in the superior colliculus are altered with age. Extracellular single-unit recordings were conducted in the superior colliculus of anesthetized Sprague-Dawley adult (10-12 months) and aged (21-22 months) rats. Looming circular concentric sinusoidal (CCS) gratings were presented alone and in the presence of sinusoidally amplitude modulated white noise. In both groups of rats, two different audiovisual response interactions were encountered in the spatial domain: superadditive, and suppressive. In contrast, additive audiovisual interactions were found only in adult rats. Hence, superior colliculus audiovisual interactions were more numerous in adult rats (38%) than in aged rats (8%). These results suggest that intersensory interactions in the superior colliculus play an essential role in space processing toward audiovisual moving objects during self-motion. Moreover, aging has a deleterious effect on complex audiovisual interactions. Copyright © 2016 IBRO. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Pyomyositis is a primary bacterial infection of striated muscles nearly always caused by Staphylococcus aureus. Development of the intramuscular abscess involving the extra-ocular muscles (EOMs remains an extremely rare process. We herein present a case of isolated EOM pyomyositis involving superior rectus muscle in a 2-year male child who was referred with complaints of swelling in left eye (LE and inability to open LE since last 1-month. Orbital computed tomography (CT scan showed a well-defined, hypo-dense, peripheral rim-enhancing lesion in relation to left superior rectus muscle suggestive of left superior rectus abscess. The abscess was drained through skin approach. We concluded that pyomyositis of EOM should be considered in any patient presenting with acute onset of orbital inflammation and characteristic CT or magnetic resonance imaging features. Management consists of incision and drainage coupled with antibiotic therapy.

    We describe the surgical technique of reimplantation of the right superior pulmonary vein into the left atrium in 2 patients with partial anomalous pulmonary venous connection to the superior vena cava without atrial septal defect. A right axillary minithoracotomy is done through the fourth intercostal space. The pulmonary vein is detached from its origin in the superior vena cava. This is sutured with 6-0 reabsorbable polydioxanone suture (Ethicon, Somerville, NJ). A lateral clamp is applied to the left atrium, and the pulmonary vein is reimplanted. The patient is extubated in the operating room. Neither cardiopulmonary bypass nor blood transfusion was required. It is simple, safe, and reproducible.

    2010-01-01

    Chest X-ray is routinely performed to check the position of the central venous catheter (CVC) inserted through the internal jugular or subclavian vein, while the further evaluation of CVC malfunction is usually performed by contrast venography. In patients with superior vena cava obstruction, the tip of the catheter is often seen in collateral mediastinal venous pathways, rather than in the superior vena cava. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. We report a case of 32-year-old female patient with relapsing mediastinal lymphoma and previous superior vena cava obstruction with collateral azygos-hemiazygos venous pathways. The patient had CVC inserted through the left subclavian vein and its position was detected by CT to be in the dilated left superior intercostal vein and accessory hemiazygos vein. Considering that dilated accessory hemiazygos vein can tolerate infusion, the CVC was left in place and the patient had no complaints related to CVC (mal)position. Furthermore, we present anatomical and radiological observations on the azygos-hemiazygos venous system with the special emphasis on the left superior intercostal vein. Non-contrast CT scans can be a valuable imaging tool in the detection of the CVC position, especially in patients with renal insufficiency and contrast media hypersensitivity

    1955-01-01

    Bottom trawling by the U. S. Fish and Wildlife Service motor vessel Cisco in Lake Superior in 1952–1953 revealed a large population of a tiny whitefish, Coregonus (Prosopium) coulteri, which has been reported previously only from northwestern North America. The hiatus in range, from Lake Superior to the Columbia River basin, is the greatest known for a North American freshwater fish. Although minor structural differences characterize the disjunct populations of the pygmy whitefish, these are not deemed worthy of nomenclatorial recognition. Comparisons with related species indicate that the pygmy whitefish is distinctive in the small size, large scales, few vertebrae, few pyloric caeca, and in other characters.

    2011-01-01

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    2012-01-01

    To establish the surgical results and residual symptoms in 48 cases with unilateral congenital superior oblique muscle palsy that had surgical intervention to the vertical muscles alone. Myectomy and concomitant disinsertion of the inferior oblique (IO) muscle was performed in 38 cases and myectomy and concomitant IO disinsertion and recession of the superior rectus muscle in the ipsilateral eye was performed in 10 cases. The preoperative and postoperative vertical deviation values and surgical results were compared. Of the patients who had myectomy and concomitant IO disinsertion, 74% achieved an "excellent" result, 21% a "good" result, and 5% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Of the patients who had myectomy and concomitant inferior oblique disinsertion and ipsilateral superior rectus recession, 50% achieved an "excellent" result, 20% a "good" result, and 30% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Both procedures are effective and successful in patients with superior oblique muscle palsy, but a secondary surgery may be required. Copyright 2012, SLACK Incorporated.

  3. QUAL DEMOCRATIZAÇÃO DO ENSINO SUPERIOR?

    Directory of Open Access Journals (Sweden)

    François Dubet

    Full Text Available Esse artigo, resultante de uma conferência, discute traços do processo de democratização do ensino superior. Procura distinguir analiticamente várias dimensões da democratização, baseadas, por sua vez, em concepções diferentes da justiça: igualdade de oportunidades, meritocracia, utilidades e equidade dos procedimentos. Cada sociedade constrói modelos de democratização desse ensino. A massificação do ensino superior desempenhou papel democrático objetivo, favorável aos grupos sociais antes excluídos. Mas massificação não equivale à democratização. Todas as categorias sociais não se beneficiam da mesma forma da massificação. A democratização do acesso ao ensino superior não depende apenas das famílias. Depende também da estrutura geral do sistema educativo. A meritocracia acadêmica constrói uma hierarquia de competências que é também social, com forte impacto reprodutivo. As desigualdades de utilidade das diferentes formações têm impacto sobre o conjunto das desigualdades sociais. Os sistemas educativos implementam distintos procedimentos de seleção, de concessão de gratuidades, bolsas e auxílios, que podem ser considerados como mais ou menos equitativos segundo as normas de justiça que mobilizam.

    Full Text Available Introduction: Superior oblique split lengthening (SOSL is done for weakening of superior oblique. It corrects the superior oblique overaction (SOOA and A pattern. Its effect on the torsion of the eye is not known. We present our data on the effect of this particular procedure on torsion. Materials and Methods: We did a study of 16 patients (32 eyes who underwent bilateral SOSL and compared the disc foveal angle (DFA preoperatively and postoperatively. The split lengthening was done from 4 mm to 7 mm depending upon the overaction of superior oblique. Results: The mean age was 15.3 ± 8.4 years. Mean preoperative DFA in the right eye (RE was −3.9° and in the left eye (LE was −2.9°. Mean postoperative DFA in RE was 0.2° and in LE was 0.9°. The mean change in the DFA for RE was 4.1° ± 1.3° and for LE was 3.8° ± 1.2°. All the patients were aligned horizontally within 6 prism diopter and no pattern and no diplopia postoperatively. The A pattern was corrected in all the patient postsurgery. For each mm of surgery, an improvement of 0.8° was seen in the DFA. Conclusion: We report the effect of SOSL on torsion. The SOSL reduces intorsion postsurgery and is, therefore, a valuable procedure in SOOA where both pattern and in torsion needs to be corrected.

    2016-04-01

    Hippocampal sclerosis is the most common cause of drug-resistant epilepsy amenable for surgical treatment and seizure control. The rationale of the selective amygdalohippocampectomy is to spare cerebral tissue not included in the seizure generator. Describe the selective amygdalohippocampectomy through the trans-superior temporal gyrus keyhole approach. Selective amygdalohippocampectomy for temporal lobe epilepsy is performed when the data (semiology, neuroimaging, electroencephalography) point to the mesial temporal structures. The trans-superior temporal gyrus keyhole approach is a minimally invasive and safe technique that allows disconnection of the temporal stem and resection of temporomesial structures.

  7. Frequency of the superior rectus muscle overaction/contracture syndrome in unilateral fourth nerve palsy.

    Molinari, Andrea; Ugrin, Maria Cristina

    2009-12-01

    Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Overaction and contracture of the ipsilateral superior rectus muscle in patients with unilateral fourth (trochlear) nerve palsy is seldom discussed in the literature. The purpose of this study is to evaluate the frequency of superior rectus muscle overaction/contracture syndrome in patients with unilateral trochlear nerve palsy. The records of 198 patients with unilateral trochlear nerve palsy examined by the authors between July 1987 and July 2008 were reviewed retrospectively. All patients underwent complete eye examination with measurement of the deviation in the 9 positions of gaze and with the head tilted to both sides in all cooperative patients. Selection criteria for superior rectus muscle overaction/contracture syndrome in these patients were as follows: vertical deviation of 15(Delta) or larger in primary position, equal or larger hypertropia with the ipsilateral forced tilt test than with the eyes looking straight ahead, more than 5(Delta) hypertropia of the affected eye in horizontal gaze to the same side, hypertropia in all upgazes, and overaction of the contralateral superior oblique muscle. Of 198 patients, 33 (16.6%) met the selection criteria for superior rectus muscle overaction/contracture syndrome. Superior rectus muscle overaction/contracture syndrome frequently occurs in unilateral superior oblique palsy.

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    2017-06-09

    Anthropogenic climate change has the potential to alter many facets of Earth's freshwater resources, especially lacustrine ecosystems. The effects of anthropogenic changes in Lake Superior, which is Earth's largest freshwater lake by area, are not well documented (spatially or temporally) and predicted future states in response to climate change vary. Here we show that Lake Superior experienced a slow, steady increase in production throughout the Holocene using (paleo)productivity proxies in lacustrine sediments to reconstruct past changes in primary production. Furthermore, data from the last century indicate a rapid increase in primary production, which we attribute to increasing surface water temperatures and longer seasonal stratification related to longer ice-free periods in Lake Superior due to anthropogenic climate warming. These observations demonstrate that anthropogenic effects have become a prominent influence on one of Earth's largest, most pristine lacustrine ecosystems.

    The majority of individuals evaluate themselves as superior to average. This is a cognitive bias known as the "superiority illusion." This illusion helps us to have hope for the future and is deep-rooted in the process of human evolution. In this study, we examined the default states of neural and molecular systems that generate this illusion, using resting-state functional MRI and PET. Resting-state functional connectivity between the frontal cortex and striatum regulated by inhibitory dopaminergic neurotransmission determines individual levels of the superiority illusion. Our findings help elucidate how this key aspect of the human mind is biologically determined, and identify potential molecular and neural targets for treatment for depressive realism.

  14. Mechanism of the superior mechanical strength of nanometer-sized metal single crystals revealed

    KAUST Repository

    Afify, N. D.

    2013-10-01

    Clear understanding of the superior mechanical strength of nanometer-sized metal single crystals is required to derive advanced mechanical components retaining such superiority. Although high quality studies have been reported on nano-crystalline metals, the superiority of small single crystals has neither been fundamentally explained nor quantified to this date. Here we present a molecular dynamics study of aluminum single crystals in the size range from 4.1 nm to 40.5 nm. We show that the ultimate mechanical strength deteriorates exponentially as the single crystal size increases. The small crystals superiority is explained by their ability to continuously form vacancies and to recover them. © 2013 Published by Elsevier B.V.

    2006-06-01

    Full Text Available A Síndrome de Deiscência de Canal Semicircular Superior (SDCSS, primeiramente descrita em 1998 por Minor et al., caracteriza-se por vertigem associada à presença de nistagmo, relacionados à exposição a estímulos sonoros intensos ou a modificações de pressão dentro da orelha média ou intracraniana. Disacusia, em sua maioria de padrão condutivo à audiometria tonal, também pode estar presente. Nesta revisão da literatura objetivou-se abordar a SDCSS, com seus principais sinais e sintomas, achados diagnósticos e tratamento, assim como enfatizar a importância de sua inclusão dentre as causas de vertigem, visto tratar-se de acometimento ainda pouco conhecido até mesmo entre especialistas. O diagnóstico correto, além de possibilitar seu tratamento, impede que abordagens diagnósticas e terapêuticas inapropriadas sejam realizadas.The Superior Canal Dehiscence Syndrome (SCDS was first reported by Minor at. Al. (1998, and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.

    MRI examinations were carried out on the defined congenital superior oblique palsy in order to distinguish the congenital and acquired palsies. Subjects were 19 patients diagnosed as congenital and their MRI images of 3 or 5 mm-thick coronary slice were taken. The volume of the oblique muscle was calculated from the images and a comparison was made between the diseased and healthy normal sides. The oblique muscle volume at the diseased side was found reduced in most of congenital superior oblique palsy patients. The reduction was observed even at childhood and was thus considered to be a malformation. Further, it is conceivable that the palsy could be caused by the abnormality in the central nervous system as well as by the present anatomical abnormality. (K.H.)

    Hoff, Michael H.; Todd, Thomas N.

    2004-01-01

    The shortjaw cisco (Coregonus zenithicus) was historically found in Lakes Huron, Michigan, and Superior, but has been extirpated in Lakes Huron and Michigan apparently as the result of commercial overharvest. During 1999-2001, we conducted an assessment of shortjaw cisco abundance in five areas, spanning the U.S. waters of Lake Superior, and compared our results with the abundance measured at those areas in 1921-1922. The shortjaw cisco was found at four of the five areas sampled, but abundances were so low that they were not significantly different from zero. In the four areas where shortjaw ciscoes were found, abundance declined significantly by 99% from the 1920s to the present. To increase populations of this once economically and ecologically important species in Lake Superior, an interagency rehabilitation effort is needed. Population monitoring is recommended to assess population trends and to evaluate success of rehabilitation efforts.

  19. Acute Bilateral Superior Branch Vestibular Neuropathy

    Dario A. Yacovino

    2018-05-01

    Full Text Available The rapid onset of a bilateral vestibular hypofunction (BVH is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

A aspiração crescente pelo ensino superior obriga os governos a gerir os custos de funcionamento desse sistema. As respostas de cada país variam com sua história, cultura e regime político. Todos eles enfrentam problemas semelhantes, como escassez de recursos e o poder político de atores do sistema de ensino superior e fora dele. Cinco dilemas se apresentam aos países: 1 expansão, igualdade de acesso e diversificação das matrículas, taxas de participação, o número e os tipos de instituições; 2 limitações financeiras; 3 regulação do ensino superior privado; 4 como fazer com que as instituições de ensino superior prestem mais contas a seus alunos, funcionários e à sociedade como um todo; e 5 qualidade e relevância social da aprendizagem e pesquisa em instituições de ensino superior. Utilizando dados e evidências das pesquisas mais recentes, o artigo mostra respostas comuns, com algumas exceções em cada caso: diversificação institucional; políticas de ação afirmativa; crescimento das matrículas nas ciências sociais, humanidades, profissões sociais e Educação; pouco sucesso nas políticas de internacionalização.

    Full Text Available Aim: The superior gluteal nerve may be compromised during hip surgery. We retrospectively evaluated the patients who underwent proximal femoral nailing for unstable trochanteric fractures in order to investigate the presence of superior gluteal nerve injury and its clinical findings. Material and Method: Twenty five patients (14 women, 11 men were included in the study who had femoral nailing between January 2004 and March 2010 at Hamidiye Sisli Etfal Training and Research Hospital Department of Orthopaedics. Two different types of nails which have similar designs and surgical techniques were used for fracture fixation. Patients who had a history of cerebrovascular disease, electromyography findings of polyneuropathy, or degenerative vertebral disease were excluded from the study. Patients were evaluated clinically and radiologically. Findings related to acute denervation in the gluteus medius muscle and motor unit action potential changes were accepted as signs of superior gluteal nerve injury. Results: Eight patients were using support during walking and three of these patients had positive Trendelenburg sign, but only one patient had acute denervation signs of the superior gluteal nerve. Discussion: Based on the present study the incidence of iatrogenic nerve injury is a rare complication of proximal femoral nailing. Elderly patients, regardless of whether they have nerve injury, may limp and need to use a walking support.

    The present study focuses on influences of long-term experience on auditory processing, providing the first evidence for pre-attentively superior auditory processing in musicians. This was revealed by the brain's automatic change-detection response, which is reflected electrically as the mismatch negativity (MMN) and generated by the operation of sensoric (echoic) memory, the earliest cognitive memory system. Major chords and single tones were presented to both professional violinists and non-musicians under ignore and attend conditions. Slightly impure chords, presented among perfect major chords elicited a distinct MMN in professional musicians, but not in non-musicians. This demonstrates that compared to non-musicians, musicians are superior in pre-attentively extracting more information out of musically relevant stimuli. Since effects of long-term experience on pre-attentive auditory processing have so far been reported for language-specific phonemes only, results indicate that sensory memory mechanisms can be modulated by training on a more general level.

    Information Superiority generated through proper application of Geoinformatics Information management and especially geoscience information delivery is a very delicate task. If it is carried out successfully, geoscientific data will provide the main foundation of Information Superiority. However, improper implementation of geodata generation, assimilation, distribution or storage will not only waste valuable resources like manpower or money, but could also give rise to crucial deficiency in knowledge and might lead to potentially extremely harmful disasters or wrong decisions. Comprehensive Approach, Effect Based Operations and Network Enabled Capabilities are the current buzz terms in the security regime. However, they also apply to various interdisciplinary tasks like catastrophe relief missions, civil task operations or even in day to day business operations where geo-science data is used. Based on experience in the application of geoscience data for defence applications the following procedure or tool box for generating geodata should lead to the desired information superiority: 1. Understand and analyse the mission, the task and the environment for which the geodata is needed 2. Carry out a Information Exchange Requirement between the user or customer and the geodata provider 3. Implementation of current interoperability standards and a coherent metadata structure 4. Execute innovative data generation, data provision, data assimilation and data storage 5. Apply a cost-effective and reasonable data life cycle 6. Implement IT security by focusing of the three pillar concepts Integrity, Availability and Confidentiality of the critical data 7. Draft and execute a service level agreement or a memorandum of understanding between the involved parties 8. Execute a Continuous Improvement Cycle These ideas from the IT world should be transferred into the geoscience community and applied in a wide set of scenarios.

    Outcomes following repair of superior canal dehiscence (SCD) are variable, and surgery carries a risk of persistent or recurrent SCD symptoms, as well as a risk of hearing loss and vestibulopathy. Poor outcomes may occur from inadequate repair of the SCD or mechanical insult to the membranous labyrinth. Repair of SCD using a customized, fixed-length prosthesis may address current operative limitations and improve surgical outcomes. We aim to 3-dimensionally print customized prostheses to resurface or occlude bony SCD defects. Dehiscences were created along the arcuate eminence of superior semicircular canals in cadaveric temporal bones. Prostheses were designed and created using computed tomography and a 3-dimensional printer. The prostheses occupied the superior semicircular canal defect, reflected in postrepair computed tomography scans. This novel approach to SCD repair could have advantages over current techniques. Refinement of prosthesis design and materials will be important if this approach is translated into clinical use. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2015.

    Full Text Available Non-exudative age-related macular degeneration, a prevalent cause of blindness, is a progressive and degenerative disease characterized by alterations in Bruch's membrane, retinal pigment epithelium, and photoreceptors exclusively localized in the macula. Although experimental murine models exist, the vast majority take a long time to develop retinal alterations and, in general, these alterations are ubiquitous, with many resulting from non-eye-specific genetic manipulations; additionally, most do not always reproduce the hallmarks of human age-related macular degeneration. Choroid vessels receive sympathetic innervation from the superior cervical ganglion, which, together with the parasympathetic system, regulates blood flow into the choroid. Choroid blood flow changes have been involved in age-related macular degeneration development and progression. At present, no experimental models take this factor into account. The aim of this work was to analyze the effect of superior cervical gangliectomy (also known as ganglionectomy on the choroid, Bruch's membrane, retinal pigment epithelium and retina. Adult male C57BL/6J mice underwent unilateral superior cervical gangliectomy and a contralateral sham procedure. Although superior cervical gangliectomy induced ubiquitous choroid and choriocapillaris changes, it induced Bruch's membrane thickening, loss of retinal pigment epithelium melanin content and retinoid isomerohydrolase, the appearance of drusen-like deposits, and retinal pigment epithelium and photoreceptor atrophy, exclusively localized in the temporal side. Moreover, superior cervical gangliectomy provoked a localized increase in retinal pigment epithelium and photoreceptor apoptosis, and a decline in photoreceptor electroretinographic function. Therefore, superior cervical gangliectomy recapitulated the main features of human non-exudative age-related macular degeneration, and could become a new experimental model of dry age

El tratamiento de preferencia es la Trombólisis IV (Intra Venosa con rt-PA (Recombinant Tissue Plasminogen Activator - Activador del Plasminógeno Tisular Recombinante, el cual tiene una ventana de eficacia de 4 horas y media después del inicio de los síntomas. Sólo 2% de los pacientes eligibles para este tratamiento se benefician de una fibrinólisis por vía venosa. Las oclusiones de arterias de calibre grueso son responsables del 46% de los accidentes cerebrovasculares Isquémicos (ACVI y predicen una sobremortalidad y discapacidad funcional severa a los 6 meses. En ausencia de revascularización, la mitad de los ACVI de circulación anterior con oclusión arterial documentada fallece y solamente el 10% de ellos, tienen un buen pronóstico funcional a los tres meses.

    2013-09-01

    Full Text Available La transferencia libre del colgajo radial de antebrazo se emplea en la práctica clínica habitual en numerosos procedimientos reconstructivos. Sin embargo, también es popular debido a la potencial morbilidad que se genera en la zona donante del colgajo: trastornos vasculares, motores, sensitivos o estéticos. A pesar de haberse realizado numerosas modificaciones tanto en la disección del colgajo como en el cierre del defecto, hasta la actualidad ninguno de los procedimientos empleados ha demostrado paliar completamente estas secuelas. Presentamos nuestra experiencia con la utilización de un colgajo de rotación-avance en V-Y fasciocutáneo basado en los vasos perforantes de la arteria cubital para el tratamiento del defecto resultante de la transferencia libre del colgajo antebraquial radial. Hemos empleado este procedimiento en 7 pacientes con edades comprendidas entre los 30 y los 86 años. Las dimensiones del colgajo radial en el eje longitudinal del antebrazo fueron desde los 4 a los 5,5 cm, con un eje transversal al pedículo vascular desde los 8 a los 10 cm. En todos los casos se conservó la motricidad de antebrazo- muñeca-mano-dedos sin registrarse adherencias a nivel tendinoso. No observamos alteraciones en la fuerza ni en la sensibilidad respecto al preoperatorio en el antebrazo intervenido. Las cicatrices fueron estéticamente aceptables. Concluimos que el colgajo fasciocutáneo de rotación-avance en V-Y basado en perforantes de la arteria cubital aporta numerosas ventajas frente a los injertos cutáneos u otros sustitutos dérmicos, además de ser más barato, con un período de cicatrización más rápido y con un resultado estético superior.

    Patients with schizophrenia (n = 24) matched with 24 normal subjects were presented with both words and pictures. On a recognition memory task, they were asked to give remember, know, or guess responses to items that were recognized on the basis of conscious recollection, familiarity, or guessing, respectively. Compared with normal subjects, patients exhibited a lower picture superiority effect selectively related to remember responses. Unlike normal subjects, they did not exhibit any word superiority effect in relation to guess responses; this explains why the overall picture superiority effect appeared to be intact. These results emphasize the need to take into account the subjective states of awareness when analyzing memory impairments in schizophrenia.

    Certain heart fetal planes must be realized during a routine obstetric ultrasound in order to identify a group of anomalies such as the persistency of the left superior caval vein. When an isolated left superior venal vein is identified without any other anomaly of the fetal heart, it does not have any perinatal repercussion. Its importance lies in the fact that a considerable number of these cases are associated with a high incidence of congenital heart diseases and anatomic and chromosomal abnormalities. This article reports nine cases of persistency of the left superior caval vein as well as the associated heart abnormalities and the extra-cardiac alterations found.

    Full Text Available l neoliberalismo se ha convertido en el “telón de fondo” de los ajustes de la política en la educación superior a nivel mundial, que no se limitan ya al recorte en la asignación de recursos o a su privatización, sino que afectan básicamente a los núcleos centrales del ideario educativo y a las políticas pedagógicas. Los conflictos que se dirimen en la educación superior no son más que una parte de la crisis más general de la política y de la ciudadanía en el capitalismo global. Con el argumento de que la educación superior debe atender a las demandas sociales, se hace una interpretación claramente reduccionista de qué sea la sociedad, poniendo a la universidad al exclusivo servicio de las empresas y se centra la formación en preparar exclusivamente el tipo de trabajadores y trabajadoras solicitados por éstas. Las inversiones en la educación superior y los currículos deben ser pensados de acuerdo con las exigencias del mercado y como preparación al mercado de trabajo. El papel público de la educación superior como campo de entrenamiento para la democracia y para la ciudadanía democrática se ha pasado a considerar como un despilfarro del gasto público, siendo reemplazado por el punto de vista que la empresa privada tiene de la función de la enseñanza superior: un campo de entrenamiento para atender las necesidades de las empresas. La persona trabajadora “flexible” y “polivalente” constituye así la referencia del nuevo ideal pedagógico. El problema de fondo es el marco global en el que se inscribe y la filosofía que orienta esta reforma y que parece desplegar un funcionamiento mercantil de la educación en Europa. Porque esta reforma no parece tratar de poner la universidad al servicio de la sociedad para hacerla más justa, más sabia, más universal, más equitativa, más comprensiva, sino de adaptar la universidad al mercado, una parte muy concreta de la sociedad, cuyas finalidades no se orientan

    In the auditory cortex (AC), corticofugal projections arise from each level of the auditory system and are considered to provide feedback "loops" important to modulate the flow of ascending information. It is well established that the cortex can influence the response of neurons in the superior colliculus (SC) via descending corticofugal projections. However, little is known about the relative contribution of different pyramidal neurons to these projections in the SC. We addressed this question by taking advantage of anterograde and retrograde neuronal tracing to directly examine the laminar distribution, long-range projections, and electrophysiological properties of pyramidal neurons projecting from the AC to the SC of the mouse brain. Here we show that layer 5 cortico-superior-collicular pyramidal neurons act as bandpass filters, resonating with a broad peak at ∼3 Hz, whereas layer 6 neurons act as low-pass filters. The dissimilar subthreshold properties of layer 5 and layer 6 cortico-superior-collicular pyramidal neurons can be described by differences in the hyperpolarization-activated cyclic nucleotide-gated cation h-current (Ih). Ih also reduced the summation of short trains of artificial excitatory postsynaptic potentials injected at the soma of layer 5, but not layer 6, cortico-superior-collicular pyramidal neurons, indicating a differential dampening effect of Ih on these neurons. © The Author 2017.

    Pseudoaneurysm of the superior gluteal artery (SGA) is very rare and the most common causes are blunt or penetrating pelvic traumas. Although pseudoaneurysm can be asymptomatic at the time of initial trauma, it can be symptomatic weeks, months, even years after initial trauma. We present a case of a ruptured superior gluteal artery pseudoaneurysm with hemorrhagic shock twenty days after a bomb injury in the Syria civil war. In addition, we review the anatomy of the SGA, clinical presentation and pitfalls of pseudoaneurysm, and imaging and treatment options.

    Full Text Available Integration in a workplace is an interaction rapport between the individual and the environment. The process of professional integration is strongly linked to the professional aspiration, individual expectations, motivation, and work satisfaction. Placing young graduates of superior studies on the labour market is a challenge for contemporary society. Identifying a suitable work place as well as the certainty of the attained work place are very important elements for young superior studies graduates in the current context of economic crysis. The difficulties in getting a job for superior studies graduates are most frequently associated with lacks in what regards the speciality practical skills and generally, insertion in the work market is achived by getting a position in fields that are related or even different from the speciality field. In an extremely unstable social and economic context, people’s ability to quickly adapt to the requirements of the labour market is fundamental. In this respect, education and professional training have an important role, contributing to the update of knowledge, skills and qualifications of superior studies graduates or future superior studies graduates, eventually allowing them to stay active, flexible, adapted to the situations and requirements of the labour market.

    Prior reports of preferential detection of emotional expressions in visual search have yielded inconsistent results, even for face stimuli that avoid obvious expression-related perceptual confounds. The current study investigated inconsistent reports of anger and happiness superiority effects using face stimuli drawn from the same database. Experiment 1 excluded procedural differences as a potential factor, replicating a happiness superiority effect in a procedure that previously yielded an anger superiority effect. Experiments 2a and 2b confirmed that image colour or poser gender did not account for prior inconsistent findings. Experiments 3a and 3b identified stimulus set as the critical variable, revealing happiness or anger superiority effects for two partially overlapping sets of face stimuli. The current results highlight the critical role of stimulus selection for the observation of happiness or anger superiority effects in visual search even for face stimuli that avoid obvious expression related perceptual confounds and are drawn from a single database.

    Full Text Available Abstract Introduction Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta. Case presentation We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle. Conclusions This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.

    The recent identification of highly superior autobiographical memory (HSAM) raised the possibility that there may be individuals who are immune to memory distortions. We measured HSAM participants’ and age- and sex-matched controls’ susceptibility to false memories using several research paradigms. HSAM participants and controls were both susceptible to false recognition of nonpresented critical lure words in an associative word-list task. In a misinformation task, HSAM participants showed higher overall false memory compared with that of controls for details in a photographic slideshow. HSAM participants were equally as likely as controls to mistakenly report they had seen nonexistent footage of a plane crash. Finding false memories in a superior-memory group suggests that malleable reconstructive mechanisms may be fundamental to episodic remembering. Paradoxically, HSAM individuals may retrieve abundant and accurate autobiographical memories using fallible reconstructive processes. PMID:24248358

    A key factor in the decline of memory with age may be a breakdown of communication in the information network involved in memory and cognitive processing. A special case of this communication is assumed to underlie the picture superiority effect in recall. From this hypothesis it follows that the picture superiority effect should lessen with age. In Experiment 1, three groups of adults (young, old normal, and old memory-impaired) were tested in free recall of pictures and word lists. As predicted, the picture superiority effect declined with age. Experiment 2 replicated these findings and showed, moreover, that the picture superiority effect can be reestablished in normal old adults by instructing them to verbalize overtly during item presentation.

    Carbon dots (CDs) have various applications in biomedical and environmental field, such as bio-imaging, bio-sensing and heavy metal detection. In this study, a novel class of CDs were synthesized using a one-step hydrothermal method. The fabricated CDs displayed stable photoluminescence, good water solubility, and photo stability. Moreover, the functional groups (carboxylic acid moieties and hydroxyls) on the surface of the obtained CDs enable it with superior sensing ability (e.g., very low detectable concentration for Pb2+: 5 nmol/L). With superior detection sensitivity, excellent fluorescent properties and facile fabrication method, the as-obtained CDs can find practical applications as cost-effective and sensitive chemo-sensors in water and food safety field.

    2006-01-01

    According to leading theories, the picture superiority effect is driven by conceptual processing, yet this effect has been difficult to obtain using conceptual implicit memory tests. We hypothesized that the picture superiority effect results from conceptual processing of a picture's distinctive features rather than a picture's semantic features. To test this hypothesis, we used 2 conceptual implicit general knowledge tests; one cued conceptually distinctive features (e.g., "What animal has large eyes?") and the other cued semantic features (e.g., "What animal is the figurehead of Tootsie Roll?"). Results showed a picture superiority effect only on the conceptual test using distinctive cues, supporting our hypothesis that this effect is mediated by conceptual processing of a picture's distinctive features.

  14. Superiorized algorithm for reconstruction of CT images from sparse-view and limited-angle polyenergetic data

    Recent work in CT image reconstruction has seen increasing interest in the use of total variation (TV) and related penalties to regularize problems involving reconstruction from undersampled or incomplete data. Superiorization is a recently proposed heuristic which provides an automatic procedure to ‘superiorize’ an iterative image reconstruction algorithm with respect to a chosen objective function, such as TV. Under certain conditions, the superiorized algorithm is guaranteed to find a solution that is as satisfactory as any found by the original algorithm with respect to satisfying the constraints of the problem; this solution is also expected to be superior with respect to the chosen objective. Most work on superiorization has used reconstruction algorithms which assume a linear measurement model, which in the case of CT corresponds to data generated from a monoenergetic x-ray beam. Many CT systems generate x-rays from a polyenergetic spectrum, however, in which the measured data represent an integral of object attenuation over all energies in the spectrum. This inconsistency with the linear model produces the well-known beam hardening artifacts, which impair analysis of CT images. In this work we superiorize an iterative algorithm for reconstruction from polyenergetic data, using both TV and an anisotropic TV (ATV) penalty. We apply the superiorized algorithm in numerical phantom experiments modeling both sparse-view and limited-angle scenarios. In our experiments, the superiorized algorithm successfully finds solutions which are as constraints-compatible as those found by the original algorithm, with significantly reduced TV and ATV values. The superiorized algorithm thus produces images with greatly reduced sparse-view and limited angle artifacts, which are also largely free of the beam hardening artifacts that would be present if a superiorized version of a monoenergetic algorithm were used.

  15. The picture superiority effect in patients with Alzheimer's disease and mild cognitive impairment.

    The fact that pictures are better remembered than words has been reported in the literature for over 30 years. While this picture superiority effect has been consistently found in healthy young and older adults, no study has directly evaluated the presence of the effect in patients with Alzheimer's disease (AD) or mild cognitive impairment (MCI). Clinical observations have indicated that pictures enhance memory in these patients, suggesting that the picture superiority effect may be intact. However, several studies have reported visual processing impairments in AD and MCI patients which might diminish the picture superiority effect. Using a recognition memory paradigm, we tested memory for pictures versus words in these patients. The results showed that the picture superiority effect is intact, and that these patients showed a similar benefit to healthy controls from studying pictures compared to words. The findings are discussed in terms of visual processing and possible clinical importance.

    Full Text Available Investing in portfolio of assets is the best way to reduce the investment risk. The most desired portfolio can be obtained when investors chose to invest in the portfolios that lay on the portfolio’s efficient frontier. However, the superiorities of the portfolios are difficult to differentiate especially when the efficient frontier curves are overlapping. This paper proposed the portfolio’s efficient frontier center of gravity (CoG and Euclidean distance to identify its superiority. A sample of 49 stocks of large-cap and small-cap were used to construct two hypothetical portfolios and its efficient frontiers. The Euclidean distance showed that the large-cap portfolio is superior and having wider feasible solutions compared to the small-cap portfolio. The results of new tool introduced are consistent with the conventional methods. Here the theoretical and practical implications are provided in light of the findings.

  2. A Multifactorial Mechanism in the Superior Antimalarial Activity of α-C-GalCer

    2010-01-01

    Full Text Available We have previously shown that the C-glycoside analog of α-galactosylceramide (α-GalCer, α-C-GalCer, displays a superior inhibitory activity against the liver stages of the rodent malaria parasite Plasmodium yoelii than its parental glycolipid, α-GalCer. In this study, we demonstrate that NK cells, as well as IL-12, are a key contributor for the superior activity displayed by α-C-GalCer. Surprisingly, the diminished production of Th2 cytokines, including IL-4, by α-C-GalCer has no affect on its superior therapeutic activity relative to α-GalCer. Finally, we show that the in vivo administration of α-C-GalCer induces prolonged maturation of dendritic cells (DCs, as well as an enhanced proliferative response of mouse invariant Vα14 (Vα14i NKT cells, both of which may also contribute to some degree to the superior activity of α-C-GalCer in vivo.

    To compare superior ophthalmic vein diameter and extraocular muscle index in patients with thyroid eye disease with or without optic neuropathy. High-resolution CT scan images of 40 orbits of 20 patients with history of thyroid eye disease (with or without optic neuropathy), who underwent orbital decompression surgery from January 2007 to November 2009, were retrospectively reviewed. Superior ophthalmic vein diameter was measured in coronal and axial planes. Extraocular muscle index was calculated according to the method proposed by Barrett et al. The clinical diagnosis of optic neuropathy was based on characteristic signs that included afferent pupillary defect, decreased visual acuity, visual field defects, and dyschromatopsia. Orbits were divided in 2 groups based on presence or absence of optic neuropathy. Superior ophthalmic vein diameter was significantly higher in orbits with concomitant optic neuropathy (mean 2.4 ± 0.4mm, p optic neuropathy (mean 57.9% ± 5.7%, p = 0.0002). Muscle index greater than 50% was present in all patients with dysthyroid optic neuropathy. This study suggests that patients with thyroid eye disease with enlarged superior ophthalmic vein and increased extraocular muscle index are more likely to have concomitant optic neuropathy.

    Dyslexia is an impairment of reading and spelling that affects both children and adults even after many years of schooling. Dyslexic readers have deficits in the integration of auditory and visual inputs but the neural mechanisms of the deficits are still unclear. This fMRI study examined the neural processing of auditorily presented German numbers 0-9 and videos of lip movements of a German native speaker voicing numbers 0-9 in unimodal (auditory or visual) and bimodal (always congruent) conditions in dyslexic readers and their matched fluent readers. We confirmed results of previous studies that the superior temporal gyrus/sulcus plays a critical role in audiovisual speech integration: fluent readers showed greater superior temporal activations for combined audiovisual stimuli than auditory-/visual-only stimuli. Importantly, such an enhancement effect was absent in dyslexic readers. Moreover, the auditory network (bilateral superior temporal regions plus medial PFC) was dynamically modulated during audiovisual integration in fluent, but not in dyslexic readers. These results suggest that superior temporal dysfunction may underly poor audiovisual speech integration in readers with dyslexia. Copyright © 2017 IBRO. Published by Elsevier Ltd.

    2003-01-01

    We occasionally see decrease in attenuation in the superior segment of the left lower lobe on normal chest CT and notice that this finding could be seen in elder population. Then, we assessed the frequency, age distribution and cause of decrease in attenuation in the superior segment of the left lower lobe. Chest CT scans of 246 patients without lung or cardiac disorders were retrospectively reviewed. Segmental low attenuation area in the superior segment of the left lower lobe was identified in 12 patients (4.9%), which were 65-92 years old with mean age of 77.2 years old. In all of them, chest CT demonstrated that the tortuous descending aorta compressed directly the superior segmental bronchus of the left lower lobe. It is concluded that the lateral tortuousity of the descending aorta could cause decrease in attenuation in the superior segment of the left lower lobe. (author)

    Superior orbital fissure syndrome is a rare complication that occurs in association with craniofacial trauma. The characteristics of superior orbital fissure syndrome are attributable to a constellation of cranial nerve III, IV, and VI palsies. This is the largest series describing traumatic superior orbital fissure syndrome that assesses the recovery of individual cranial nerve function after treatment. In a review from 1988 to 2002, 33 patients with superior orbital fissure syndrome were identified from 11,284 patients (0.3 percent) with skull and facial fractures. Severity of cranial nerve injury and functional recovery were evaluated by extraocular muscle movement. Patients were evaluated on average 6 days after initial injury, and average follow-up was 11.8 months. There were 23 male patients. The average age was 31 years. The major mechanism of injury was motorcycle accident (67 percent). Twenty-two received conservative treatment, five were treated with steroids, and six patients underwent surgical decompression of the superior orbital fissure. After initial injury, cranial nerve VI suffered the most damage, whereas cranial nerve IV sustained the least. In the first 3 months, recovery was greatest in cranial nerve VI. At 9 months, function was lowest in cranial nerve VI and highest in cranial nerve IV. Eight patients (24 percent) had complete recovery of all cranial nerves. Functional recovery of all cranial nerves reached a plateau at 6 months after trauma. Cranial nerve IV suffered the least injury, whereas cranial nerve VI experienced the most neurologic deficits. Cranial nerve palsies improved to their final recovery endpoints by 6 months. Surgical decompression is considered when there is evidence of bony compression of the superior orbital fissure.

    Full Text Available Words are made of letters, and yet sometimes it is easier to identify a word than a single letter. This word superiority effect (WSE has been observed when written stimuli are presented very briefly or degraded by visual noise. We compare performance with letters and words in three experiments, to explore the extents and limits of the WSE. Using a carefully controlled list of three letter words, we show that a word superiority effect can be revealed in vocal reaction times even to undegraded stimuli. With a novel combination of psychophysics and mathematical modelling, we further show that the typical WSE is specifically reflected in perceptual processing speed: single words are simply processed faster than single letters. Intriguingly, when multiple stimuli are presented simultaneously, letters are perceived more easily than words, and this is reflected both in perceptual processing speed and visual short term memory capacity. So, even if single words come easy, there is a limit to the word superiority effect.

    Highly Superior Autobiographical Memory (HSAM) is characterized as the ability to accurately recall an exceptional number of experiences and their associated dates from events occurring throughout much of one’s lifetime. The source of this ability has only begun to be explored. The present study explores whether other enhanced cognitive processes may be critical influences underlying HSAM abilities. We investigated whether enhanced abilities in the domains of verbal fluency, attention/inhibition, executive functioning, mnemonic discrimination, perception, visual working memory, or the processing of and memory for emotional details might contribute critically to HSAM. The results suggest that superior cognitive functioning is an unlikely basis of HSAM, as only modest advantages were found in only a few tests. In addition, we examined HSAM subjects’ memory of the testing episodes. Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them. These findings provide additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material. PMID:26982996

  14. Cognitive abilities and superior decision making under risk

    Directory of Open Access Journals (Sweden)

    Edward T. Cokely

    2009-02-01

    Full Text Available Individual differences in cognitive abilities and skills can predict normatively superior and logically consistent judgments and decisions. The current experiment investigates the processes that mediate individual differences in risky choices. We assessed working memory span, numeracy, and cognitive impulsivity and conducted a protocol analysis to trace variations in conscious deliberative processes. People higher in cognitive abilities made more choices consistent with expected values; however, expected-value choices rarely resulted from expected-value calculations. Instead, the cognitive ability and choice relationship was mediated by the number of simple considerations made during decision making --- e.g., transforming probabilities and considering the relative size of gains. Results imply that, even in simple lotteries, superior risky decisions associated with cognitive abilities and controlled cognition can reflect metacognitive dynamics and elaborative heuristic search processes, rather than normative calculations. Modes of cognitive control (e.g., dual process dynamics and implications for process models of risky decision-making (e.g., priority heuristic are discussed.

  15. Superior metallic alloys through rapid solidification processing (RSP) by design

    Energy Technology Data Exchange (ETDEWEB)

    Flinn, J.E. [Idaho National Engineering Laboratory, Idaho Falls, ID (United States)

    1995-05-01

    Rapid solidification processing using powder atomization methods and the control of minor elements such as oxygen, nitrogen, and carbon can provide metallic alloys with superior properties and performance compared to conventionally processing alloys. Previous studies on nickel- and iron-base superalloys have provided the baseline information to properly couple RSP with alloy composition, and, therefore, enable alloys to be designed for performance improvements. The RSP approach produces powders, which need to be consolidated into suitable monolithic forms. This normally involves canning, consolidation, and decanning of the powders. Canning/decanning is expensive and raises the fabrication cost significantly above that of conventional, ingot metallurgy production methods. The cost differential can be offset by the superior performance of the RSP metallic alloys. However, without the performance database, it is difficult to convince potential users to adopt the RSP approach. Spray casting of the atomized molten droplets into suitable preforms for subsequent fabrication can be cost competitive with conventional processing. If the fine and stable microstructural features observed for the RSP approach are preserved during spray casing, a cost competitive product can be obtained that has superior properties and performance that cannot be obtained by conventional methods.

  16. Levels of processing and picture memory: the physical superiority effect.

    Science.gov (United States)

    Intraub, H; Nicklos, S

    1985-04-01

    Six experiments studied the effect of physical orienting questions (e.g., "Is this angular?") and semantic orienting questions (e.g., "Is this edible?") on memory for unrelated pictures at stimulus durations ranging from 125-2,000 ms. Results ran contrary to the semantic superiority "rule of thumb," which is based primarily on verbal memory experiments. Physical questions were associated with better free recall and cued recall of a diverse set of visual scenes (Experiments 1, 2, and 4). This occurred both when general and highly specific semantic questions were used (Experiments 1 and 2). Similar results were obtained when more simplistic visual stimuli--photographs of single objects--were used (Experiments 5 and 6). As in the case of the semantic superiority effect with words, the physical superiority effect for pictures was eliminated or reversed when the same physical questions were repeated throughout the session (Experiments 4 and 6). Conflicts with results of previous levels of processing experiments with words and nonverbal stimuli (e.g., faces) are explained in terms of the sensory-semantic model (Nelson, Reed, & McEvoy, 1977). Implications for picture memory research and the levels of processing viewpoint are discussed.

    Superior sulcus filler injection is a nonsurgical method to rejuvenate the upper face. Blindness and stroke are devastating complications of facial filler injection. This study describes an injection technique that minimizes the risk of blindness and includes a case study demonstrating the cosmetic benefits of this procedure. To avoid retrograde injection of filler embolus into the ophthalmic artery, we advocate a "'walk the rim, feel the bone" approach. Small boluses of hyaluronic acid filler are given in preperiosteal plane, avoiding the superior orbital foramen.

    Extraventricular obstructive hydrocephalus may develop after superior vena cava obstruction, an uncommon complication after cardiac surgery.Objective. To describe the neuroimaging findings in neonates and infants with superior vena cava thrombosis after cardiac surgery for congenital heart disease.Materials and methods. Between 1993 and 2001, 333 neonates and infants in our hospital underwent cardiac surgery, of whom 13 (3.9%) subsequently acquired superior vena cava syndrome. Eleven of these 13 children (7 boys, 4 girls) were evaluated by head ultrasound and computed tomography scans.Results. One child had normal findings on head ultrasound, and 10 children had extraventricular obstructive hydrocephalus (EVOH). In 6 children, aggravation of the hydrocephalus was noted up to 11.4 months after cardiac surgery; in 3 of them, the hydrocephalus was shunted to the peritoneum. One child had thrombosis of the dural sinuses, and 1 had hemorrhagic infarction. Two children died during follow-up.Conclusion. EVOH is a common complication of superior vena cava thrombosis, and head ultrasound should be performed in all neonates and infants with superior vena cava thrombosis after cardiac surgery. Long-term follow-up is needed, as the hydrocephalus may worsen even months after surgery. (orig.)

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    Superior wear of the glenoid bone is common in patients with rotator cuff arthropathy. This can become a treatment challenge for patients who require shoulder arthroplasty. In reverse shoulder arthroplasty (RSA), glenoid bone loss may affect the stability of baseplate fixation. The primary purpose of this biomechanical laboratory study was to assess the initial fixation stability of RSA glenosphere baseplates in the presence of variable amounts of superior glenoid bone loss. High-density solid rigid polyurethane foam (30 pounds/cubic foot) was machined to model the glenoid with variable superior defects that provided different levels of support (100%, 90%, 75%, and 50%) for the glenosphere baseplate. The samples were cyclically loaded (0-750 N at 1 Hz for 5000 cycles) at a 60° glenohumeral angle. The micromotion and migration of the baseplate were calculated from displacement data captured during the loading tests with an array of 3 linear variable differential transformers mounted around the baseplate. Micromotion was significantly greater in samples with 50% defects compared with those with smaller defects. Migration was significantly greater after testing for all defect sizes. Initial fixation of RSA glenosphere baseplates was significantly reduced in models with 50% bone loss on the superior edge compared with models with less bone loss in this high-density bone foam model.

    The middle longitudinal fascicle (MdLF) is a major fiber connection running principally between the superior temporal gyrus and the parietal lobe, neocortical regions of great biological and clinical interest. Although one of the most prominent cerebral association fiber tracts, it has only recently been discovered in humans. In this high angular resolution diffusion imaging (HARDI) MRI study, we delineated the two major fiber connections of the human MdLF, by examining morphology, topography, cortical connections, biophysical measures, volume and length in seventy-four brains. These two fiber connections course together through the dorsal temporal pole and the superior temporal gyrus maintaining a characteristic topographic relationship in the mediolateral and ventrodorsal dimensions. As these pathways course towards the parietal lobe, they split to form separate fiber pathways, one following a ventrolateral trajectory and connecting with the angular gyrus and the other following a dorsomedial route and connecting with the superior parietal lobule. Based on the functions of their cortical affiliations, we suggest that the superior temporal-angular connection of the MdLF, i.e., STG(MdLF)AG plays a role in language and attention, whereas the superior temporal-superior parietal connection of the MdLF, i.e., STG(MdLF)SPL is involved in visuospatial and integrative audiovisual functions. Furthermore, the MdLF may have clinical implications in neurodegenerative disorders such as primary progressive aphasia, frontotemporal dementia, posterior cortical atrophy, corticobulbar degeneration and Alzheimer's disease as well as attention-deficit/hyperactivity disorder and schizophrenia.

    Authors measured the superior temporal gyrus volume by 3D MRI imaging for the schizophrenics and simultaneously recorded the P300 component during the auditory odd-ball exercise. Subjects were 8 cases of schizophrenics and the sex- and age-matched healthy control adults. In schizophrenics, the superior temporal gyrus volume reduction was found. When the superior temporal gyrus was divided into two parts, the anterior part containing the primary auditory area, and the posterior part containing the planum temporale and the Wernicle speech area, the volume reduction of left side in the posterior part was remarkable. There was no difference in the latent time and the P300 amplitude between schizophrenics and healthy controls, suggesting that the superior temporal gyrus abnormalities will appear prior to P300 abnormalities. We could not find any correlation between findings of MRI and P300 and psychic symptoms. We discuss the possible contribution on the elucidation of the pathogenesis of the schizophrenia by simultaneous recordings of 3D MRI imaging and the event-related potentials. (K.H.)

    Mycotic aneurysms of the aorta and the visceral arteries are life-threatening diseases, due to potential rupture and organ or limb ischemia. They occur in endocarditis, immunodeficiency, bacteremia and fungemia, and have a poor prognosis.We report on a case of a 54-year-old male patient suffering from abdominal angina after mitral valve replacement for septic mycotic endocarditis. In presence of a mycotic-embolic occlusion of the left popliteal artery and multiple septic organ infarctions a mycotic aneurysm of the superior mesenteric artery was found in abdominal spiral-CT.Based on sequential spiral-CT examinations, this case demonstrates the development of a septic aneurysm of the superior mesenteric artery.

    The form change paradigm was used to explore the basis for the picture superiority effect. Recognition memory for studied pictures and words was tested in their study form or the alternate form. Form change cost was defined as the difference between recognition performance for same and different form items. Based on the results of Experiment 1 and previous studies, it was difficult to determine the relative cost for studied pictures and words due to a reversal of the mirror effect. We hypothesized that the reversed mirror effect results from subjects' basing their recognition decisions on their assumptions about the study form. Experiments 2 and 3 confirmed this hypothesis and generated a method for evaluating the relative cost for pictures and words despite the reversed mirror effect. More cost was observed for pictures than words, supporting the distinctiveness model of the picture superiority effect.

En este orden de cosas, el panorama trazado de la situación actual de la educación superior y las políticas relacionadas con la misma en Europa se articula en torno a cinco propuestas de análisis que abundan en aspectos tales como: en las políticas nacionales de educación superior desde hace cincuenta años se ha prestado una atención cada vez mayor a los temas europeos e internacionales pero partir de la década de 1990 las políticas nacionales de este nivel son, al mismo tiempo, políticas europeas e internacionales y las políticas europeas e internacionales de educación superior en Europa son, al mismo tiempo, políticas nacionales. En la actualidad se tiende a configurar un sistema europeo de educación superior en un mundo globalizado aunque las viejas políticas no desaparecen por ello, con lo que las políticas europeas e internacionales de educación superior se vuelven crecientemente complejas. Con todo, la europeización de las políticas de educación superior de los países europeos o de los cuerpos europeos supranacionales en ningún momento contradijeron sustancialmente las políticas internacionales. Finalmente, las políticas de investigación de los países europeos occidentales y de las organizaciones supranacionales activas en Europa siempre fueron impulsadas por otras justificaciones racionales, aparte de las políticas de educación superior.

    For suprasellar meningioma, the fronto-basal exposure is considered the standard approach. The superior interhemispheric (IH) approach is less described in the literature. To assess the surgical complications, functional outcome (visual, olfaction), morbidity and mortality rates and late recurrence, after resection by superior IH approach of midline skull base meningioma. Between 1998 and 2008, 52 consecutive patients with midline meningioma on the anterior portion of the skull base (mean age: 63.8 ± 13.1; sex ratio F/M: 3.7) were operated on via the superior IH approach. After a mean follow-up of 56.9 ± 32.9 months, an independent neurosurgeon proposed a prospective examination of functional outcome to each patient, as well as a visual and olfactory function assessment. Fifty-two patients were divided into a group with olfactory groove meningioma (n=34) and another with tuberculum sellae meningioma (n=18). The outcome was characterized by postoperative complications in 13 patients (25%), mortality rate in two (3.8%) and long-term morbidity at in 17 (37%) of 50 surviving patients. Based on multivariate analysis, no prognosis factor was significant as regards the favorable outcome. The mean postoperative KPS score (86.6 ± 9.4) was significantly improved. However, dysexecutive syndrome was observed in four patients (8%), hyposmia-anosmia in 34 (68%) and visual acuity deteriorated in one (2%). The superior IH approach could be considered a safe anteriorly orientated midline approach for removal OGM and TSM meningioma. Copyright © 2011. Published by Elsevier Masson SAS.

    Full Text Available Este artigo situa-se na fronteira do debate geral das políticas de educação superior. Tais políticas estão vinculadas às estratégias de inserção da economia nas grandes transformações em âmbito mundial. Nesse contexto, são instaurados processos de avaliação da educação superior que contribuem para a redefinição da relação entre o Estado e o sistema de ensino superior. É nessa perspectiva que se situa o objeto deste estudo – identificar o modelo de gestão pública que conduziu a incorporação formal e definitiva da avaliação como ato regulatório e compulsório no primeiro Governo FHC (1995-2002. De caráter descritivo, com uma abordagem qualitativa, na revisão de literatura destacamos as características do Estado Burocrático e do Estado Gerencial. Igualmente, estudamos o conceito e o significado de eficiência no plano administrativo de ambos os Estados. Os resultados mostraram que o modelo de gestão pública estava em transição, quando a política pública denominada avaliação da educação superior tornou-se regulatória, definitiva e compulsória no país, pois mesmo tendo a base no modelo Gerencial, tal concretização só foi possível por meio de ações burocráticas ancoradas no excesso de legislações. Conclui-se que a emergência da avaliação da educação superior na década de 90 ampliou a burocracia.

    2009-01-01

    The fact that pictures are better remembered than words has been reported in the literature for over 30 years. While this picture superiority effect has been consistently found in healthy young and older adults, no study has directly evaluated the presence of the effect in patients with Alzheimer’s disease (AD) or mild cognitive impairment (MCI). Clinical observations have indicated that pictures enhance memory in these patients, suggesting that the picture superiority effect may be intact. However, several studies have reported visual processing impairments in AD and MCI patients which might diminish the picture superiority effect. Using a recognition memory paradigm, we tested memory for pictures versus words in these patients. The results showed that the picture superiority effect is intact, and that these patients showed a similar benefit to healthy controls from studying pictures compared to words. The findings are discussed in terms of visual processing and possible clinical importance. PMID:18992266

      Analisa-se a participação das universidades estaduais no ensino superior do Brasil, comparando-as com as federais, municipais e privadas em termos do número de instituições, vagas, ingressantes, matrículas e concluintes antes e depois da Lei de Diretrizes e Bases da Educação Nacional. Pergunta-se: qual a contribuição para o ensino superior brasileiro e que efeitos as inovações da LDB provocaram no setor? Deseja-se dimensionar essa participação, comparando a parcela de contribuição das UEs com a dos demais segmentos antes das inovações da lei geral. Tomam-se por base os Censos do Ensino Superior realizados pelo INEP, analisando a proporção do segmento em relação ao total. Constatou-se que as estaduais são as primeiras instituições universitárias e que, salvo nas primeiras décadas, quando a federalização subtraiu algumas unidades, até 1996, ampliava sua participação com 20% das instituições, 15% dos ingressantes, 17% das matrículas, 19% de concluintes e  13% das vagas. Desde então, apesar dos acréscimos, tem reduzido sua fatia, tendo, em 2013, 19% das universidades, 5% das vagas, 8% dos ingressantes, 13% das matrículas e 14% dos concluintes, não acompanhando o crescimento das federais e, principalmente, das privadas que, favorecidas com as alterações na legislação, tornaram-se o maior segmento. Conclui-se, então, que a participação das universidades estaduais no ensino superior brasileiro tem experimentado ora ampliação, ora redução, mas sempre favorecendo o acesso ao ensino superior de grandes camadas da população brasileira.   Palavras-chave: Ensino superior.

    Full Text Available Accountability and superior auditing of public resources are basic conditions of modern democracies and part of the state reform. To reinforce accountability and superior audit institutions it is proposed to integrate a National System of Accountability and Superior Auditing. This System is meant to enhance the effectiveness of the internal and external controls and to promote the efficiency, efficacy, ethics, legality and austerity in the use of public resources. It is necessary to implement strategies to assure the superior audit institutions, at the Federal and state level, with financial independence and administrative autonomy, training and civil service granted in the Political Constitution. Part of the System will be the National Institute of Accountability and Superior Audit. This Institute will promote training, the best audit and evaluation techniques and the accountability and austerity culture. Finally, the Citizen Accountability Consultative Council, will provide a forum of discussion, opinion and free expression regarding accountability and the correct use of public resources.

    Full Text Available These experiments were performed to test the perfusion of ovine as a model for human ovaries by cryoprotectants in vivo at high temperature when the permeability of capillaries is high and when blood is insensibly replaced by the solution of cryoprotectants. By our hypothetical supposition, ovaries could be saturated by cryoprotectants before their surgical removal. The objective was to examine the effectiveness of perfusion of ovine ovaries with vascular pedicle in vivo and in vitro. Arteria ovarica was cannuled and ovaries were perfused by Leibovitz L-15 medium + 100 IU/mL heparin + 5% bovine calf serum + 6% dimethyl sulfoxide + 6% ethylene glycol + 0.15 M sucrose + Indian ink in vivo and in vitro. In the first and second cycle of experiments, ovaries (n=13 and n=23 were perfused in vivo and in vitro, respectively, during 60 min with the rate of perfusion 50 mL/h (0.8 mL/min. It was established with in vivo perfusion that only about 10% of ovarian tissues were perfused due to an appearance of multiple anastomoses when the perfusion medium goes from arteria ovarica to arteria uterina without inflow into the ovaries. It was concluded that in vitro perfusion of ovine intact ovaries with vascular pedicle by freezing medium is more effective than this manipulation performed in vivo.

    The patient was a 25-year-old male college student with a chief complaint of right shoulder pain. The patient was initially diagnosed with bicipital tendinitis by his physician and had been treated for 4 weeks by a physical therapist. However, his symptoms did not improve and he was unable to return to his preinjury activity levels, so he sought the services of another physical therapist for a second opinion. Due to concern for a labrum tear, the physical therapist referred the patient to an orthopaedic surgeon. Magnetic resonance arthrography revealed findings consistent with a superior labrum anterior-to-posterior tear.

Se evaluó: edad, sexo, tiempo de evolución de la sintomatología, hallazgos intraoperatorios y resultados postoperatorios. Resultados: De los 13 pacientes intervenidos, 7 fueron mujeres y 6 varones. La media de edad fue de 53 años. El tiempo medio entre el inicio de la sintomatología y la intervención quirúrgica osciló entre 3 y 9 años. En todos los casos el EHF era típico, uno de ellos con neuralgia trigeminal concomitante, observándose en todos compresión neurovascular intraoperatoria. Por orden decreciente de frecuencia la causa de la compresión fue arteria cerebelosa anteroinferior, arteria cerebelosa posteroinferior, arteria dolicomega basilar y arteria dolicomega vertebral. El seguimiento postoperatorio fue en promedio de 24 meses. El 62% presentó desaparición postquirúrgica inmediata de la sintomatología preoperatoria, el 30% desaparición tras un período de 3 semanas a 2 meses (8% con mejoría parcial), y en el 8% no hubo mejoría. En cuanto a las complicaciones postoperatorias: 3 pacientes presentaron paresia facial II-III en la escala de House-Brackman (se recuperaron en un período de 6 meses), y 1 paciente presentó fístula de líquido cefalorraquídeo. Ninguno de los pacientes de la serie presentaron hipoacusia transitorio o permanente. Conclusión: La DMV como tratamiento del EHF es un procedimiento efectivo y seguro, que permite la resolución completa de la patología en la mayoría de los casos. PMID:27127708

    Neuronal lipofuscin characteristics in the superior temporal gyrus from 21 patients with Alzheimer's disease (AD) and from 18 age-matched non-diseased subjects were compared with previously reported findings from the superior frontal gyrus. A discriminant function analysis of lipofuscin characteristics in the superior temporal gyrus did not provide a significant predictive level for cases whose diagnoses were correctly classified (56.4%, P=0.63). In contrast, AD-related decrease in the number of smaller lipofuscin regions in the neurons of the frontal gyrus was confirmed, and the same analysis of lipofuscin characteristics in this region gave a significant predictive level for membership of the AD group of 86.6% (P<0.001). The findings indicate that changes in neuronal lipofuscin related to AD, which may reflect an increased rate of lipofuscin formation, show differences between neocortical regions. This study provides additional information on the distribution of neuropathological characteristics in AD.

    Smith, Aubrey; Chitre, Vivek; Deo, Hersh

    2012-12-17

    Acute compartment syndrome affecting the gluteal region is rare when compared to the same condition in the forearm or calf. When it does occur, it is usually due to prolonged immobilisation in those with altered consciousness. Gluteal compartment syndrome resulting from injury to the superior gluteal artery is extremely rare and to our knowledge has been described only twice--both after high-energy road traffic accidents (RTA). Other cases have described profound hypotension with superior gluteal artery injury after an RTA and falling off a horse, without acute gluteal compartment syndrome. We present a case of gluteal compartment syndrome due to rupture of the superior gluteal artery following a relatively minor fall. The patient required an emergency fasciotomy, which was performed within 4 h of the injury. This case highlights the importance of early diagnosis and treatment of this rare condition.

    Full Text Available Before initiating the building operations for the «Palos Verdes» School, the site was divided into two large horizontal surfaces, at different levels. The lower one served to accommodate the playing fields, a car park, the physical training building, and shop and ancillary buildings. On the higher of these two surfaces, and to the West of the access road, there is a car park and also the building and plot of ground devoted to agricultural technology, as well as the literary studies and general purpose buildings. As a complement to these, there is a series of blocks, arranged in parallel rows, which house the administrative offices, the art school, the craft's school, the general classrooms, and those devoted to higher education. The fascinating aspect of this school is the outstanding penetration of the architect's mind into the essential function of the project. Its most evident merit is the sense of comradeship and harmony that permeates the whole architectural manifold.Antes de construir el complejo escolar «Palos Verdes» se comenzó por crear, en el terreno, dos grandes mesetas a niveles diferentes. Sobre el inferior se organizaron: los campos de juegos, de deportes, un aparcamiento, el edificio para educación física y los destinados a tiendas y servicios. Sobre la meseta superior, al oeste de la vía de acceso, se dispuso un aparcamiento y el edificio y campo para adiestramiento agrícola; al este, otro aparcamiento, el edificio dedicado a materias literarias, y el destinado a usos múltiples. Completan las instalaciones de la escuela una serie de bloques paralelos: la administración, la escuela de arte, las clases de trabajos manuales, las aulas de enseñanzas generales, y las de los cursos superiores. Lo fascinante de este complejo escolar es la perfecta y magistral compenetración del arquitecto con el tema proyectado, y su mayor mérito, la sensación de cordialidad y armonía con el ambiente.

    Cisco Coregonus artedi form pre-spawning aggregations in Lake Superior during November with the bulk of spawning occurring during late November through early December (Dryer and Beil 1964). Eggs are broadcast into open water (Smith 1956) with fertilized eggs settling to the lakebed (Dryer and Beil 1964). Peak hatching occurs the following May (United States Geological Survey – Great Lakes Science Center, GLSC, unpublished data). Interannual variability in year class strength is high, but tends to be synchronous across different regions of Lake Superior (Bronte et al. 2003). November 2005 sampling of Thunder Bay showed 14 year-classes were present with the oldest fish being from the 1984 year-class (Yule et al. 2008). The ciscoes sampled were predominantly from five year classes that hatched during 1988, 1989, 1990, 1998, and 2003. These same strong year-classes were found in the western arm of Lake Superior during November 2006 (GLSC, unpublished data). Growth is rapid in the first few years of life with minimal growth after age-8 (Yule et al. 2008). Ciscoes exceeding 250 mm total length (TL) are typically sexually mature (Yule et al. 2006b, 2008). Thunder Bay ciscoes have high annual survival with rates for females and males averaging 0.80 and 0.75, respectively; females have higher rates of fishing-induced mortality compared to males but lower rates of natural mortality (Yule et al. 2008). Some Lake Superior stocks are currently commercially fished with the bulk of harvest occurring during November when fishers target females for their roe. The bulk of fish are harvested from Thunder Bay using suspended gillnets with mesh sizes ranging from 79-89 mm stretch measure. Ciscoes younger then age-5 make up a very small proportion (<0.1%) of the harvest (Yule, et al. 2008).

    1985-02-01

    Sciatica caused by root entrapment in the lateral recess was named superior facet syndrome by Epstein in 1972. Few reports on this subject based on large numbers of cases have been documented to date. Of the patients with sciatica, 32 patients were diagnosed to have root entrapment at the lateral recess L5 or/and S1 lumbar spine. Out of 32 patients, 20 patients were operated on and the lateral entrapment was recognized in all of surgical cases. Neuroradiological findings, especially of metrizamide CT (met. CT), were documented in detail. Thirty two patients were classified in three types according to radiological findings. They were congenital or developmental, degenerative, and combined type, respectively. Fourteen cases belonged to the congenital type, 13 to the degenerative and 5 to the combined type. Each group had the mean ages of 23.4, 53.8, and 36.8 years old, respectively. Of 32 cases the entrapment occured in 47 L5 roots and 11 S1 roots. There was no remarkable laterality. In operation the unroofing of the lateral recess were done and the sciatica subsided postoperatively in all of surgical cases. Met. CT revealed extreme medial protrusion of the superior articular joint in 18 of 24 cases(75%) and none filling of the root in the lateral recess in 21 of 24 cases (87.5%). In the degenerative type, met. CT showed some degenerative changes that were hypertrophy or deformity of the articular joints and spur formation of the vertebral body. In contrast to met. CT, metrizamide myelography revealed only slight changes, which were poor filling of the root before it turned out the pedicle of lateral compression of the root. In plain films or lumbar spine articular joints at Lsub(4/5) were formed in coronal plane in 69% of cases of the L5 root entrapment. Met. CT using ReView technique was of great diagnostic value in superior facet syndrome.

Results: Thirty-seven patients were included in the study, [21 (59% male, 15 (41% female]. The mean age was 20.6 years at the time of operation. The mean time interval between diagnosis and operation was 7.3 years. Postoperative follow-up period was 2.04 (ranging 1-10 years. Diplopia was determined in seven (18.9% patients, and abnormal head position in 36 (97.3% patients. Only inferior oblique tenotomy with distal muscle resection was performed in 25 patients. In addition, five patients had recession of the contralateral inferior rectus muscle and two patients had recession of the ipsilateral superior rectus muscle additional to inferior oblique tenotomy. Abnormal head position was completely improved in all of the patients postoperatively. The preoperative average score of the inferior oblique muscle (IOM overaction was +3.3±0.8, and postoperative overaction was found in only two patients (+1.5.

    Previous work has reported the existence of "super-recognisers" (SRs), or individuals with extraordinary face recognition skills. However, the precise underpinnings of this ability have not yet been investigated. In this paper we examine (a) the face-specificity of super recognition, (b) perception of facial identity in SRs, (c) whether SRs present with enhancements in holistic processing and (d) the consistency of these findings across different SRs. A detailed neuropsychological investigation into six SRs indicated domain-specificity in three participants, with some evidence of enhanced generalised visuo-cognitive or socio-emotional processes in the remaining individuals. While superior face-processing skills were restricted to face memory in three of the SRs, enhancements to facial identity perception were observed in the others. Notably, five of the six participants showed at least some evidence of enhanced holistic processing. These findings indicate cognitive heterogeneity in the presentation of superior face recognition, and have implications for our theoretical understanding of the typical face-processing system and the identification of superior face-processing skills in applied settings.

    Full Text Available A 29-year-old male with a 5-year-history of hyperthyroidism complained of diplopia and proptosis. After subtotal thyroidectomy, he still had diplopia in a certain gaze. Computerized tomography showed inferior rectus muscle enlargement in the right eye and inferior rectus, medial rectus, and superior oblique muscle enlargement in the left eye. Ocular examination with the cover and uncover test revealed hyperphoria and exophoria in the left eye. The upward gaze of the right eye was more limited than that of the left eye. Since superior oblique muscle involvement in patients with thyroid orbitopathy is quite rare, we discuss its effect on ocular motility in patients with thyroid-associated orbitopathy.

    The red P anode for sodium ion batteries has attracted great attention recently due to the high theoretical capacity, but the poor intrinsic electronic conductivity and large volume expansion restrain its widespread applications. Herein, the red P is successfully encapsulated into the cube shaped sandwich-like interconnected porous carbon building (denoted as P@C-GO/MOF-5) via the vaporization-condensation method. Superior cycling stability (high capacity retention of about 93% at 2 A g -1 after 100 cycles) and excellent rate performance (502 mAh g -1 at 10 A g -1 ) can be obtained for the P@C-GO/MOF-5 electrode. The superior electrochemical performance can be ascribed to the successful incorporation of red P into the unique carbon matrix with large surface area and pore volume, interconnected porous structure, excellent electronic conductivity and superior structural stability. © 2018 WILEY-VCH Verlag GmbH & Co.

    The suprascapular notch is covered superiorly by the superior transverse scapular ligament. This region is the most common place of suprascapular nerve entrapment formation. The study was performed on 812 specimens: 86 dry scapulae, 104 formalin-fixed cadaveric shoulders, and 622 computer topography scans of scapulae. In the cases with completely ossified superior transverse scapular ligament, the following measurements were performed: proximal and distal width of the bony bridge, middle transverse and vertical diameter of the suprascapular foramen, and area of the suprascapular foramen. An ossified superior transverse scapular ligament was observed more often in men and in the right scapula. The mean age of the subjects with a completely ossified superior transverse scapular ligament was found to be similar than in those without ossification. The ossified band-shaped type of superior transverse scapular ligament was more common than the fan-shaped type and reduced the space below the ligament to a significantly greater degree. The ossified band-shaped type should be taken into consideration as a potential risk factor in the formation of suprascapular nerve entrapment. It could explain the comparable frequency of neuropathy in various populations throughout the world despite the significant differences between them in occurrence of ossified superior transverse scapular ligament.

    Longitudinal magnetic resonance imaging studies have shown progressive gray matter reduction in the superior temporal gyrus during the earliest phases of schizophrenia. It is unknown whether these progressive processes predate the onset of psychosis. To examine gray matter reduction of the superior temporal gyrus over time in individuals at risk for psychosis and in patients with first-episode psychosis. Cross-sectional and longitudinal comparisons. Personal Assessment and Crisis Evaluation Clinic and Early Psychosis Preventions and Intervention Centre. Thirty-five ultrahigh-risk individuals (of whom 12 later developed psychosis [UHRP] and 23 did not [UHRNP]), 23 patients with first-episode psychosis (FEP), and 22 control subjects recruited from the community. Volumes of superior temporal subregions (planum polare, Heschl gyrus, planum temporale, and rostral and caudal regions) were measured at baseline and follow-up (mean, 1.8 years) and were compared across groups. In cross-sectional comparisons, only the FEP group had significantly smaller planum temporale and caudal superior temporal gyrus than other groups at baseline, whereas male UHRP subjects also had a smaller planum temporale than controls at follow-up. In longitudinal comparison, UHRP and FEP patients showed significant gray matter reduction (approximately 2%-6% per year) in the planum polare, planum temporale, and caudal region compared with controls and/or UHRNP subjects. The FEP patients also exhibited progressive gray matter loss in the left Heschl gyrus (3.0% per year) and rostral region (3.8% per year), which were correlated with the severity of delusions at follow-up. A progressive process in the superior temporal gyrus precedes the first expression of florid psychosis. These findings have important implications for underlying neurobiologic features of emerging psychotic disorders and emphasize the importance of early intervention during or before the first episode of psychosis.

    Starch gel electrophoresis was used as a means of recognizing species and stocks in Lake Superior Coregonus. Allelic variability at isocitrate dehydrogenase and glycerol-3-phosphate dehydrogenase loci was recorded for samples of lake herring (Coregonus artedii), bloater (C. hoyi), kiyi (C. kiyi), and shortjaw cisco (C. zenithicus) from five Lake Superior localities. The observed frequencies of genotypes within each subsample did not differ significantly from those expected on the basis of random mating, and suggested that each subsample represented either a random sample from a larger randomly mating population or an independent and isolated subpopulation within which mating was random. Significant contingency X2 values for comparisons between both localities and species suggested that more than one randomly mating population occurred among the Lake Superior ciscoes, but did not reveal how many such populations there were. In contrast to the genetic results of this study, morphology seems to be a better descriptor of cisco stocks, and identification of cisco stocks and species will still have to be based on morphological criteria until more data are forthcoming. Where several species are sympatric, management should strive to preserve the least abundant. Failure to do so could result in the extinction or depletion of the rarer forms.

    Computed tomography (CT) of the pancreas, with its excellent display of peripancreatic anatomy, allows visualization of the major vessels entering the mesenteric root. In scans of the normal upper abdomen obtained at or just below the level of the uncinate process of the pancreas, the proximal superior mesenteric vein (SMV) easily can be identified lying on the right ventral aspect of the superior mesenteric artery (SMA). The authors have observed a characteristic abnormality in this normal vascular arrangement on CT scans of the pancreas in three adult patients with suspected chronic pancreatitis who were subsequently proved to have midgut malrotation. They called this the SMV rotation sign and believe that its detection even on CT scans limited to the level of the pancreas should alert the radiologist to the presence of a midgut malrotation that may have been unsuspected

    Evoked potentials of some auditory centers of Rhinolophidae bats to amplitude-modulated signals were studied. A synchronization response was found in the cochlear nuclei (with respect to the fast component of the response) and in the superior olivary complex (with respect to both fast and slow components of the response) within the range of frequency modulation from 50 to 2000 Hz. In the inferior colliculus a synchronized response was recorded at modulation frequencies below 150 Hz, but in the medial geniculate bodies no such response was found. Evoked responses of the superior olivary complex were investigated in detail. The lowest frequencies of synchronization were recorded within the carrier frequency range of 15-30 and 80-86 kHz. The amplitude of the synchronized response is a function of the frequency and coefficient of modulation and also of the angle of stimulus presentation.

    Pancreatoduodenectomy is an extensive procedure carrying risk of a number of postoperative complications. Of these the most common are surgical site infections (SSI), bleeding, delayed gastric emptying, and anastomotic leakage. However, the most serious complications are ones, that are rare, clinically hardly diagnosed, and if untreated, leading to the death of a patient. Among the latter complications is thrombosis of superior mesenteric vein. Its clinical signs are unspecific and diagnostics complicated. Treatment requires aggressive approach. If this is absent, intestinal necrosis with septic state, Multiple Organ Dysfunction Syndrome (MODS) and Multiple Organ Failure (MOF) lead to a death of a patient. Authors present a case of a patient after pancreatoduodenectomy, complicated by the thrombosis of superior mesenteric vein. Patient was managed by resection of the necrotic bowel, venous decompression by venous bypass from superior mesenteric vein to the right ovarian vein, and open abdomen with negative pressure wound therapy (NPWT). Patient suffered severe abdominal sepsis with need for intensive organ support. Abdomen was definitely closed on fourth NPWT redress. Patient healed without any further complications, is well and was released to the ambulatory setting. Superior mesenteric vein (VMS) thrombosis is a rare complication. It diagnosis requires high level of vigilance and once diagnosed, aggressive therapy is essential. Two goals of surgical treatment exist: resection of the necrotic bowel and facilitation of the blood outflow. Mesenteroovarian anastomosis is one of the options in treatment of thrombosis of VMS if thrombectomy is not feasible. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

  5. Superior Intraparietal Sulcus Controls the Variability of Visual Working Memory Precision.

    Limitations of working memory (WM) capacity depend strongly on the cognitive resources that are available for maintaining WM contents in an activated state. Increasing the number of items to be maintained in WM was shown to reduce the precision of WM and to increase the variability of WM precision over time. Although WM precision was recently associated with neural codes particularly in early sensory cortex, we have so far no understanding of the neural bases underlying the variability of WM precision, and how WM precision is preserved under high load. To fill this gap, we combined human fMRI with computational modeling of behavioral performance in a delayed color-estimation WM task. Behavioral results replicate a reduction of WM precision and an increase of precision variability under high loads (5 > 3 > 1 colors). Load-dependent BOLD signals in primary visual cortex (V1) and superior intraparietal sulcus (IPS), measured during the WM task at 2-4 s after sample onset, were modulated by individual differences in load-related changes in the variability of WM precision. Although stronger load-related BOLD increase in superior IPS was related to lower increases in precision variability, thus stabilizing WM performance, the reverse was observed for V1. Finally, the detrimental effect of load on behavioral precision and precision variability was accompanied by a load-related decline in the accuracy of decoding the memory stimuli (colors) from left superior IPS. We suggest that the superior IPS may contribute to stabilizing visual WM performance by reducing the variability of memory precision in the face of higher load. This study investigates the neural bases of capacity limitations in visual working memory by combining fMRI with cognitive modeling of behavioral performance, in human participants. It provides evidence that the superior intraparietal sulcus (IPS) is a critical brain region that influences the variability of visual working memory precision between and

    Full Text Available Objective To investigate superior mesenteric artery flow measurement by Doppler ultrasonography as a means of characterizing inflammatory activity in Crohn's disease. Materials and Methods Forty patients were examined and divided into two groups – disease activity and remission – according to their Crohn's disease activity index score. Mean superior mesenteric artery flow volume was calculated for each group and correlated with Crohn's disease activity index score. Results The mean superior mesenteric artery flow volume was significantly greater in the patients with active disease (626 ml/min ± 236 × 376 ml/min ± 190; p = 0.001. As a cut off corresponding to 500 ml/min was utilized, the superior mesenteric artery flow volume demonstrated sensitivity of 83% and specificity of 82% for the diagnosis of Crohn's disease activity. Conclusion The present results suggest that patients with active Crohn's disease have increased superior mesenteric artery flow volume as compared with patients in remission. Superior mesenteric artery flow measurement had a good performance in the assessment of disease activity in this study sample.

    1987-09-01

    Heat- and alcohol-resistant bacteria for alcoholic fermentation were separated from the soils in Japan and abroad and the performance was evaluated to develop superior bacteria for ethanol fermentation. The superior bacteria pertinent to alcoholic fermentation were bred by domestication, variation treatment, cell fusion and gene manipulation. The productivity of ethanol was increased by controlling pH of thermophilic, aerobic cellulase and culturing the mixture of added nutrients. CMC ase and Beta-glucosidase genes, the component enzymes of cellulase, were successfully developed by Zymomonas sp. A promotor selecting vector of Zymomonas was produced for developing xylolase gene to acquire an active promotor.

  11. Do Superior or Inferior Interlaminar Approach or Bevel Orientation Predispose to Nonepidural Needle Penetration?

    2017-10-01

    There is a paucity of evidence-based literature regarding the advantages and disadvantages of the interlaminar approach and needle bevel orientation for performing a lumbar interlaminar epidural steroid injection (ESI). The purpose of this study was to determine if superior versus inferior lamina approach, needle bevel tip orientation, or both may predispose to inadvertent nonepidural penetration during lumbar interlaminar ESI. A prospective study was performed of patients with low back pain with or without radicular pain or neurogenic claudication referred for lumbar interlaminar ESI. Two hundred eleven patients were randomized by interlaminar approach (superior vs inferior) and bevel tip orientation (cranial vs caudal). Lumbar interlaminar ESI was performed by six interventionalists of varying levels of experience using fluoroscopic guidance with curved tip epidural needles, using loss-of-resistance technique and confirmation with contrast opacification. Exact Poisson regression was used to model the study outcome. Two hundred twenty-one lumbar interlaminar ESIs were performed on 211 patients, randomized to a superior (n = 121) or inferior lamina approach (n = 100) and to a cranial (n = 103) or caudal (n = 118) orientation of the bevel tip. Epidural needle placement was confirmed in 96.4% (n = 213) of cases. Nonepidural needle placement was most commonly associated with superior lamina approach and caudal bevel tip orientation, which was marginally significant (adjusted risk ratio, 6.88; 95% CI, 0.93-∞; p = 0.059). Inadvertent nonepidural needle penetration during fluoroscopically guided lumbar interlaminar ESI appears to be affected by approach, with superior lamina approach and caudal bevel tip orientation being the least favorable technique.

    Many nuclear power plants have been constructed in Japan and electric power generation is now highly dependent on this technology. Therefore, the needs for facilities that will enrich and reprocess nuclear fuel from nuclear power stations will be high. As there are areas with high levels of radiation, the cables which can be used in these environments are needed. We have developed a superior radiation-resistant cable which uses halogen flame-retardant materials. This radiation-resistant cable consists of Ethylene-propylene rubber (EPDM) insulation and Chlorosulfonated polyethylene (CSM) sheath can be safely used in areas with high levels of radiation. We developed this product to aid in disaster prevention. Non-halogen, flame-retardant EPDM is used for the insulation, and low-halogen, flame-retardant CSM and new non-halogen, flame-retardant materials are used for the sheath. These cables have superior flame-retardant properties and generate little smoke on corrosive gas. This products can hence reduce the danger of a secondary disaster in a fire. We expect that these cables will find application in areas with high levels of radiation. (author).

    Previous research has found that pictures (e.g., a picture of an elephant) are remembered better than words (e.g., the word "elephant"), an empirical finding called the picture superiority effect (Paivio & Csapo. Cognitive Psychology 5(2):176-206, 1973). However, very little research has investigated such memory differences for other types of sensory stimuli (e.g. sounds or odors) and their verbal labels. Four experiments compared recall of environmental sounds (e.g., ringing) and spoken verbal labels of those sounds (e.g., "ringing"). In contrast to earlier studies that have shown no difference in recall of sounds and spoken verbal labels (Philipchalk & Rowe. Journal of Experimental Psychology 91(2):341-343, 1971; Paivio, Philipchalk, & Rowe. Memory & Cognition 3(6):586-590, 1975), the experiments reported here yielded clear evidence for an auditory analog of the picture superiority effect. Experiments 1 and 2 showed that sounds were recalled better than the verbal labels of those sounds. Experiment 2 also showed that verbal labels are recalled as well as sounds when participants imagine the sound that the word labels. Experiments 3 and 4 extended these findings to incidental-processing task paradigms and showed that the advantage of sounds over words is enhanced when participants are induced to label the sounds.

    A 47-year-old female patient had a subclinical superior vena caval syndrome which developed into the \\'full blown\\' acute condition when she was placed into the left lateral position after mediastinoscopy. She developed airway obstruction requiring urgent re-intubation and subsequent admission to the intensive care unit. This subclinical condition might have been suspected pre-operatively if closer attention had been paid to the history, physical examination and review of the computerised axial tomography scan: she had a history of intermittent dysponea, wheeze and cough which was worse on waking and improved as the day progressed, she had a positive Pemberton\\'s sign and the computerised axial tomography scan showed that the lesion was encroaching on the superior vena cava.

    2011-01-01

    In a previous study (Unterrainer, Kaller, Halsband, & Rahm, 2006), chess players outperformed non-chess players in the Tower of London planning task but exhibited disproportionately longer processing times. This pattern of results raises the question of whether chess players' planning capabilities are superior or whether the results reflect differences in the speed-accuracy trade-off between the groups, possibly attributable to sports motivation. The present study was designed to disambiguate these alternative suggestions by implementing various constraints on planning time and by assessing self-reported motivation. In contrast to the previous study, chess players' performance was not superior, independently of whether problems had to be solved with (Experiment 1) or without (Experiment 2) time limits. As expected, chess players reported higher overall trait and state motivation scores across both experiments. These findings revise the notion of superior planning performance in chess players. In consequence, they do not conform with the assumption of a general transfer of chess-related planning expertise to other cognitive domains, instead suggesting that superior performance may be possible only under specific circumstances such as receiving competitive instructions.

    The market share between China Mobile and China Unicom has stabilized since 2002.It is found that China Mobile has the superiority in the competition, for example, the scissors movement between its revenue and cost indicates that it has a strong profit generating ability and there is enough room for it to reduce the price.The ratio between its price (marginal income) and marginal cost indicates that there is a very distant limit for it to reduce the price.Its demand is obviously flexible with the price, but it does not use the price weapon abundantly.The reason for the stabilization of the market is that China Mobile withdrew from the competition.

    The superior olivary complex (SOC) is a collection of brainstem auditory nuclei which play essential roles in the localization of sound sources, temporal coding of vocalizations and descending modulation of the cochlea. Notwithstanding, the SOC nuclei vary considerably between species in accordance with the auditory needs of the animal. The canine SOC was subjected to anatomical and physiological examination nearly 50 years ago and was then virtually forgotten. Herein, we aimed to characterize the nuclei of the canine SOC using quantitative morphometrics, estimation of neuronal number, histochemistry for perineuronal nets and immunofluorescence for the calcium binding proteins calbindin and calretinin. We found the principal nuclei to be extremely well developed: the lateral superior olive (LSO) contained over 20,000 neurons and the medial superior olive (MSO) contained over 15,000 neurons. In nearly all non-chiropterian terrestrial mammals, the MSO exists as a thin, vertical column of neurons. The canine MSO was folded into a U-shaped contour and had associated with the ventromedial tip a small, round collection of neurons we termed the tail nucleus of the MSO. Further, we found evidence within the LSO, MSO and medial nucleus of the trapezoid body (MNTB) for significant morphological variations along the mediolateral or rostrocaudal axes. Finally, the majority of MNTB neurons were calbindin-immunopositive and associated with calretinin-immunopositive calyceal terminals. Together, these observations suggest the canine SOC complies with the basic plan of the mammalian SOC but possesses a number of unique anatomical features. Copyright © 2017 Elsevier B.V.

    Distance effect has been regarded as the best established marker of basic numerical magnitude processes and is related to individual mathematical abilities. A larger behavioral distance effect is suggested to be concomitant with lower mathematical achievement in children. However, the relationship between distance effect and superior mathematical abilities is unclear. One could get superior mathematical abilities by acquiring the skill of abacus-based mental calculation (AMC), which can be used to solve calculation problems with exceptional speed and high accuracy. In the current study, we explore the relationship between distance effect and superior mathematical abilities by examining whether and how the AMC training modifies numerical magnitude processing. Thus, mathematical competencies were tested in 18 abacus-trained children (who accepted the AMC training) and 18 non-trained children. Electroencephalography (EEG) waveforms were recorded when these children executed numerical comparison tasks in both Arabic digit and dot array forms. We found that: (a) the abacus-trained group had superior mathematical abilities than their peers; (b) distance effects were found both in behavioral results and on EEG waveforms; (c) the distance effect size of the average amplitude on the late negative-going component was different between groups in the digit task, with a larger effect size for abacus-trained children; (d) both the behavioral and EEG distance effects were modulated by the notation. These results revealed that the neural substrates of magnitude processing were modified by AMC training, and suggested that the mechanism of the representation of numerical magnitude for children with superior mathematical abilities was different from their peers. In addition, the results provide evidence for a view of non-abstract numerical representation.

    2018-03-18

    To analyze how various implants placement variables affect sacroiliac (SI) joint range of motion. An experimentally validated finite element model of the lumbar spine and pelvis was used to simulate a fusion of the SI joint using various placement configurations of triangular implants (iFuse Implant System ® ). Placement configurations were varied by changing implant orientation, superior implant length, and number of implants. The range of motion of the SI joint was calculated using a constant moment of 10 N-m with a follower load of 400 N. The changes in motion were compared between the treatment groups to assess how the different variables affected the overall motion of the SI joint. Transarticular placement of 3 implants with superior implants that end in the middle of the sacrum resulted in the greatest reduction in range of motion (flexion/extension = 73%, lateral bending = 42%, axial rotation = 72%). The range of motions of the SI joints were reduced with use of transarticular orientation (9%-18%) when compared with an inline orientation. The use of a superior implant that ended mid-sacrum resulted in median reductions of (8%-14%) when compared with a superior implant that ended in the middle of the ala. Reducing the number of implants, resulted in increased SI joint range of motions for the 1 and 2 implant models of 29%-133% and 2%-39%, respectively, when compared with the 3 implant model. Using a validated finite element model we demonstrated that placement of 3 implants across the SI joint using a transarticular orientation with superior implant reaching the sacral midline resulted in the most stable construct. Additional clinical studies may be required to confirm these results.

  15. Data fusion in X-ray computed tomography using a superiorization approach.

    Science.gov (United States)

    Schrapp, Michael J; Herman, Gabor T

    2014-05-01

    X-ray computed tomography (CT) is an important and widespread inspection technique in industrial non-destructive testing. However, large-sized and heavily absorbing objects cause artifacts due to either the lack of penetration of the specimen in specific directions or by having data from only a limited angular range of views. In such cases, valuable information about the specimen is not revealed by the CT measurements alone. Further imaging modalities, such as optical scanning and ultrasonic testing, are able to provide data (such as an edge map) that are complementary to the CT acquisition. In this paper, a superiorization approach (a newly developed method for constrained optimization) is used to incorporate the complementary data into the CT reconstruction; this allows precise localization of edges that are not resolvable from the CT data by itself. Superiorization, as presented in this paper, exploits the fact that the simultaneous algebraic reconstruction technique (SART), often used for CT reconstruction, is resilient to perturbations; i.e., it can be modified to produce an output that is as consistent with the CT measurements as the output of unmodified SART, but is more consistent with the complementary data. The application of this superiorized SART method to measured data of a turbine blade demonstrates a clear improvement in the quality of the reconstructed image.

    To prospectively compare the accuracy of noncontrast magnetic resonance imaging (MRI) with indirect MR arthrography (I-MRa) of unexercised shoulders for diagnosis of superior glenoid labral lesions. Institutional Review Board approval and patient informed consent were obtained for this prospective study. Superior labral findings on shoulder MRI and unexercised I-MRa studies of 104 patients were correlated with findings at arthroscopic shoulder surgery. Two musculoskeletal radiologists independently reviewed the two sets of MR images while blinded to arthroscopic results. For each radiologist, the McNemar test was used to detect statistically significant differences between techniques. The superior labrum was intact in 24 and abnormal in 80 subjects. For detection of superior labral lesions by each radiologist, I-MRa was more sensitive (84-91%) than MRI (66-85%), with statistically significant improvement in sensitivity for one reader (p = 0.003). However, I-MRa was less specific (58-71%) than MRI (75-83%). Overall, accuracy was slightly improved on I-MRa (78-86%) compared with MRI (70-83%), but this difference was not statistically significant for either reader. Compared with noncontrast MRI, I-MRa was more sensitive for diagnosis of superior glenoid labral lesions. However, the diagnostic value of I-MRa in shoulders remaining at rest is potentially limited by decreased specificity of the technique. (orig.)

  1. EFFECTS OF INDIVIDUAL CHARACTERISTICS AND ORGANIZATIONAL CONTEXT ON SUPERIORS' USE OF CONFLICT STYLES AND SUBORDINATES' SATISFACTION WITH SUPERVISION

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Data from 139 respondents from major industries showed that subordinates were more satisfied with their superiors' supervision through the exercise of integrating, compromising and obliging styles. On the contrary, subordinates who perceived their superiors as primarily using dominating and avoiding styles viewed them as incompetent in supervision and thus lowering their level of satisfaction with supervision. Among the conflict handling styles, integrating was most correlated with organic structure. The organic structure was found to be positively correlated with subordinates' satisfaction. These results implied that organic structure can be a potent force in maintaining organizational stability. The exercise of dominating style was found to be only marginally correlated with superior's age. Superior rank in lower hierarchy level was found to have a negative impact, albeit marginally on the exercise of dominating style. The present results also seemed to suggest that subordinates tend to be less satisfied with superiors with wider span of control.

    In 2003, it was reported that superior semicircular canal dehiscence can mimic otosclerosis because of low-frequency bone conduction hearing gain and dissipation of air-conducted acoustic energy through the dehiscence. We report the case of a 17-year-old girl with left-sided combined hearing loss thought to be due to otosclerosis. Bone conduction thresholds were -10 dB at 250 and 500 Hz and she had a 40 dB air-bone gap at 250 Hz. When a tuning fork was placed at her ankle she heard it in her left ear. Acoustic reflexes and vestibular evoked myogenic potentials could be elicited bilaterally. Imaging of the temporal bones showed no otosclerosis, superior semicircular canal dehiscence or large vestibular aqueduct, but a left-sided, Mondini-like dysplasia of the cochlea with a modiolar deficiency could be seen. Mondini-like cochlear dysplasia should be added to the causes of inner-ear conductive hearing loss.

The knowledge of its variant branches is required for successful surgical, orthopedic, plastic surgery and radiological procedures. We observed variations of some of the branches of right IIA in an adult male cadaver. The iliolumbar artery originated from the main trunk of the IIA. After this, IIA divided into anterior and posterior divisions. The posterior division gave lateral sacral and superior gluteal arteries. Superior gluteal artery pierced the lumbosacral trunk before leaving the pelvis. The anterior division further divided into anterior and posterior trunks. Anterior trunk gave rise to superior vesical, inferior vesical, middle rectal and obturator arteries. The posterior trunk gave two inferior gluteal arteries and an internal pudendal artery.

Las razones son debidas a que el maxilar superior, en general, alberga una masa ósea de menor densidad. Por otro lado, en el maxilar superior pueden coexistir diferentes densidades óseas (según la clasificación de Misch en el mismo individuo. Además, por las características anatómicas del maxilar superior (reabsorción labiopalatina el alineamiento axial es asumible pero, sin embargo, el paralelismo de los implantes es difícil.16,17 El objetivo del presente trabajo es analizar la información científica de la que disponemos para confirmar si es posible la carga inmediata sobre el maxilar superior.

  14. Visual sensitivity of deepwater fishes in Lake Superior.

    Directory of Open Access Journals (Sweden)

    Kelly A Harrington

    Full Text Available The predator-prey interactions in the offshore food web of Lake Superior have been well documented, but the sensory systems mediating these interactions remain unknown. The deepwater sculpin, (Myoxocephalus thompsoni, siscowet (Salvelinus namaycush siscowet, and kiyi (Coregonus kiyi inhabit low light level environments. To investigate the potential role of vision in predator-prey interactions, electroretinography was used to determine visual sensitivity for each species. Spectral sensitivity curves revealed peak sensitivity at 525 nm for each species which closely corresponds to the prevalent downwelling light spectrum at depth. To determine if sufficient light was available to mediate predator-prey interactions, visual sensitivity was correlated with the intensity of downwelling light in Lake Superior to construct visual depth profiles for each species. Sufficient daytime irradiance exists for visual interactions to approximately 325 m for siscowet and kiyi and 355 m for the deepwater sculpin during summer months. Under full moon conditions, sufficient irradiance exists to elicit ERG response to light available at approximately 30 m for the siscowet and kiyi and 45 m for the deepwater sculpin. Visual interactions are therefore possible at the depths and times when these organisms overlap in the water column indicating that vision may play a far greater role at depth in deep freshwater lakes than had been previously documented.

  15. Happy Face Superiority Effect in Change Detection Paradigm

    Full Text Available The aim of the present study was to investigate which affective component guides cognitive processing of emotional facial expressions. According to the threat hypothesis, processing of angry faces is prioritized by the human cognitive system, because rapid detection of threat has a large adaptive value. The negativity hypothesis presumes that distressing emotional experiences of other people attract attention, regardless of whether they represent danger or not. The emotionality hypothesis proposes that positive emotional facial expressions can capture attention as effective as negative ones, while the happy face superiority hypothesis predicts that happy faces are prioritized. In the present study, which was conducted on 24 participants, change detection paradigm was used, because that procedure enables insight into the later stage of information processing. The results obtained show that happy facial expressions are heavily prioritized by the human cognitive system. In explanation of these results, that clearly support the happy face superiority hypothesis, we propose that angry expressions are initially prioritized by our cognitive system, because we benefit from early detection of potential threat in the environment, but in later cognitive processing, happy expressions are given the priority, because smiling is a valuable mechanism for forming and maintaining cooperative relationships. Besides the theoretical relevance, the present study is also valuable methodologically, because we demonstrated that change detection paradigm can be efficiently used for the research of emotional facial expressions processing.

    Full Text Available El artículo realiza una aproximación a los conceptos de género y calidad en educación superior en articulación con los conceptos de pertinencia y justicia social. Se reclama el sentido de pertinencia unido al de calidad como valor social, público y de compromiso con las comunidades a las que las instituciones educativas sirven. El desafío que presentamos considera que la justicia social, referida a las nociones fundamentales de igualdad de oportunidades y de derechos humanos, puede determinar la pertinencia de la educación superior, y por lo tanto su calidad. Esta perspectiva relacionada con el género se concreta en tres tesis: los procesos de producción del conocimiento no pueden desligarse de la cosmovisión de género; la profesionalización en las disciplinas sin introducir la perspectiva de género correo el riesgo de quedar sesgada hacia un polo de la dicotomía masculinidad‐feminidad; y la introducción del género en ES crea un modelo de sociedad comprometida e inclusiva.

    Faking memory impairment means normal people complain lots of memory problems without organic damage in forensic assessments. Using alternative forced-choice paradigm, containing digital or autobiographical information, previous neuroimaging studies have indicated that faking memory impairment could cause the activation in the prefrontal and parietal regions, and might involve a fronto-parietal-subcortical circuit. However, it is still unclear whether different memory types have influence on faking or not. Since different memory types, such as long-term memory (LTM) and short-term memory (STM), were found supported by different brain areas, we hypothesized that feigned STM or LTM impairment had distinct neural activation mapping. Besides that, some common neural correlates may act as the general characteristic of feigned memory impairment. To verify this hypothesis, the functional magnetic resonance imaging (fMRI) combined with an alternative word forced-choice paradigm were used in this study. A total of 10 right-handed participants, in this study, had to perform both STW and LTM tasks respectively under answering correctly, answering randomly and feigned memory impairment conditions. Our results indicated that the activation of the left superior frontal gyrus and the left medial frontal gyrus was associated with feigned LTM impairment, whereas the left superior frontal gyrus, the left precuneus and the right anterior cingulate cortex (ACC) were highly activated while feigning STM impairment. Furthermore, an overlapping was found in the left superior frontal gyrus, and it suggested that the activity of the left superior frontal gyrus might be acting as a specific marker of feigned memory impairment.

  20. Evaluating the behavior of polychlorinated biphenyl compounds in Lake Superior using a dynamic multimedia model

    Certain toxic, persistent, bioaccumulative, and semivolatile compounds known as atmosphere-surface exchangeable pollutants or ASEPs are emitted into the environment by primary sources, are transported, deposited to water surfaces, and can be later re-emitted causing the water to act as a secondary source. Polychlorinated biphenyl (PCB) compounds, a class of ASEPs, are of major concern in the Laurentian Great Lakes because of their historical use primarily as additives to oils and industrial fluids, and discharge from industrial sources. Following the ban on production in the U.S. in 1979, atmospheric concentrations of PCBs in the Lake Superior region decreased rapidly. Subsequently, PCB concentrations in the lake surface water also reached near equilibrium as the atmospheric levels of PCBs declined. However, previous studies on long-term PCB levels and trends in lake trout and walleye suggested that the initial rate of decline of PCB concentrations in fish has leveled off in Lake Superior. In this study, a dynamic multimedia flux model was developed with the objective to investigate the observed levelling off of PCB concentrations in Lake Superior fish. The model structure consists of two water layers (the epilimnion and the hypolimnion), and the surface mixed sediment layer, while atmospheric deposition is the primary external pathway of PCB inputs to the lake. The model was applied for different PCB congeners having a range of hydrophobicity and volatility. Using this model, we compare the long-term trends in predicted PCB concentrations in different environmental media with relevant available measurements for Lake Superior. We examine the seasonal depositional and exchange patterns, the relative importance of different process terms, and provide the most probable source of the current observed PCB levels in Lake Superior fish. In addition, we evaluate the role of current atmospheric PCB levels in sustaining the observed fish concentrations and appraise the need

    Highlights: • A facile and efficient strategy is firstly developed for the synthesis of Ru NPs. • Ru NPs are stable and uniform with the controllable sizes from 2.6 to 51.5 nm. • Ru NPs exhibit size-dependent and superior catalytic hydrogenation activity. - Abstract: Ruthenium (Ru) featured with an unusual catalytic behavior is of great significance in several heterogeneous and electro-catalytic reactions. The preparation of tractable Ru nanocatalysts and the building of highly active catalytic system at ambient temperature remains a grand challenge. Herein, a facile strategy is developed for the controllable preparation of Ru nanoparticles (NPs) with the sizes ranging from 2.6 to 51.5 nm. Ru NPs show superior size-dependent catalytic performance with the best kinetic rate constant as high as −1.52 min{sup −1}, which could far surpass the other traditional noble metals. Ru NPs exert exceedingly efficient low-temperature catalytic activity and good recyclability in the catalytic reduction of nitroaromatic compounds (NACs) and azo dyes. The developed catalytic system provides a distinguishing insight for the artificial preparation of Ru NPs with desired sizes, and allows for the development of rational design rules for exploring catalysts with superior catalytic performances, potentially broadening the applications of metallic NP-enabled catalytic analysis.

    Decreased cortical thickness that signifies gray matter pathology and its impact on cognitive performance is a research field with growing interest in relapsing-remitting multiple sclerosis (RRMS) and needs to be further elucidated. Using high-field 3.0 T MRI, three-dimensional T1-FSPGR (voxel size 1 × 1 × 1 mm) cortical thickness was measured in 82 regions in the left hemisphere (LH) and right hemisphere (RH) in 20 RRMS patients with low disease activity and in 20 age-matched healthy subjects that in parallel underwent comprehensive cognitive evaluation. The correlation between local cortical atrophy and cognitive performance was examined. We identified seven regions with cortical tissue loss that differed between RRMS and age-matched healthy controls. These regions were mainly located in the frontal and temporal lobes, specifically within the gyrus rectus, inferior frontal sulcus, orbital gyrus, parahippocampal gyrus, and superior temporal gyrus, with preferential left asymmetry. Increased cortical thickness was identified in two visual sensory regions, the LH inferior occipital gyrus, and the RH cuneus, implicating adaptive plasticity. Correlation analysis demonstrated that only the LH superior temporal gyrus thickness was associated with cognitive performance and its thickness correlated with motor skills (r = 0.65, p = 0.003), attention (r = 0.45, p = 0.042), and information processing speed (r = 0.50, p = 0.025). Our findings show that restricted cortical thinning occurs in RRMS patients with mild disease and that LH superior temporal gyrus atrophy is associated with cognitive dysfunction.

    Petrides, M.; Pandya, D.N.

    1988-01-01

    The projections to the frontal cortex that originate from the various areas of the superior temporal region of the rhesus monkey were investigated with the autoradiographic technique. The results demonstrated that the rostral part of the superior temporal gyrus (areas Pro, Ts1, and Ts2) projects to the proisocortical areas of the orbital and medial frontal cortex, as well as to the nearby orbital areas 13, 12, and 11, and to medial areas 9, 10, and 14. These fibers travel to the frontal lobe as part of the uncinate fascicle. The middle part of the superior temporal gyrus (areas Ts3 and paAlt) projects predominantly to the lateral frontal cortex (areas 12, upper 46, and 9) and to the dorsal aspect of the medial frontal lobe (areas 9 and 10). Only a small number of these fibers terminated within the orbitofrontal cortex. The temporofrontal fibers originating from the middle part of the superior temporal gyrus occupy the lower portion of the extreme capsule and lie just dorsal to the fibers of the uncinate fascicle. The posterior part of the superior temporal gyrus projects to the lateral frontal cortex (area 46, dorsal area 8, and the rostralmost part of dorsal area 6). Some of the fibers from the posterior superior temporal gyrus run initially through the extreme capsule and then cross the claustrum as they ascend to enter the external capsule before continuing their course to the frontal lobe. A larger group of fibers curves round the caudalmost Sylvian fissure and travels to the frontal cortex occupying a position just above and medial to the upper branch of the circular sulcus. This latter pathway constitutes a part of the classically described arcuate fasciculus

    Full Text Available En este artículo analizamos la integración de las TIC en instituciones de educación superior. Nos centramos en las prácticas de liderazgo en políticas sobre TIC, un campo de investigación que no ha recibido mucha atención en los estudios sobre educación superior. Usando un enfoque de liderazgo distribuido se analizó dicha práctica en instituciones de educación superior en Colombia, un país donde una política de incorporación de las TIC llevó a promover la elaboración de planes estratégicos en dichas instituciones. En particular, la investigación buscó entender cómo el liderazgo de las TIC es distribuido en diferentes ambientes de educación superior. A partir de un estudio de caso múltiple que incluyó entrevistas semiestructuradas con líderes y miembros de equipos, grupos focales con profesores, análisis documental y una encuesta aplicada a profesores, fueron investigadas las prácticas de liderazgo de las TIC y sus implicaciones. Los resultados indican un conjunto de tensiones que los líderes deben enfrentar cuando incorporan un plan estratégico de TIC, por ejemplo, la ausencia de regulaciones institucionales o la necesidad de promocionar el cambio educativo a pesar de las resistencias. De hecho, el liderazgo de las TIC es una práctica retadora y aún poco explorada en educación superior. Este artículo es un intento sistemático por demostrar este enunciado y sus implicaciones. Estos hallazgos son de particular relevancia para el trabajo de los diseñadores de políticas, coordinadores de TIC y líderes en educación superior de todo el mundo.

  20. The superior colliculus of the camel: a neuronal-specific nuclear protein (NeuN) and neuropeptide study

    Science.gov (United States)

    Mensah-Brown, E P K; Garey, L J

    2006-01-01

    In this study we examined the superior colliculus of the midbrain of the one-humped (dromedary) camel, Camelus dromedarius, using Nissl staining and anti-neuronal-specific nuclear protein (NeuN) immunohistochemistry for total neuronal population as well as for the enkephalins, somatostatin (SOM) and substance P (SP). It was found that, unlike in most mammals, the superior colliculus is much larger than the inferior colliculus. The superior colliculus is concerned with visual reflexes and the co-ordination of head, neck and eye movements, which are certainly of importance to this animal with large eyes, head and neck, and apparently good vision. The basic neuronal architecture and lamination of the superior colliculus are similar to that in other mammals. However, we describe for the first time an unusually large content of neurons in the superior colliculus with strong immunoreactivity for met-enkephalin, an endogenous opioid. We classified the majority of these neurons as small (perimeters of 40–50 µm), and localized diffusely throughout the superficial grey and stratum opticum. In addition, large pyramidal-like neurons with perimeters of 100 µm and above were present in the intermediate grey layer. Large unipolar cells were located immediately dorsal to the deep grey layer. By contrast, small neurons (perimeters of 40–50 µm) immunopositive to SOM and SP were located exclusively in the superficial grey layer. We propose that this system may be associated with a pain-inhibiting pathway that has been described from the periaqueductal grey matter, juxtaposing the deep layers of the superior colliculus, to the lower brainstem and spinal cord. Such pain inhibition could be important in relation to the camel's life in the harsh environment of its native deserts, often living in very high temperatures with no shade and a diet consisting largely of thorny branches.

The results demonstrated that the rostral part of the superior temporal gyrus (areas Pro, Ts1, and Ts2) projects to the proisocortical areas of the orbital and medial frontal cortex, as well as to the nearby orbital areas 13, 12, and 11, and to medial areas 9, 10, and 14. These fibers travel to the frontal lobe as part of the uncinate fascicle. The middle part of the superior temporal gyrus (areas Ts3 and paAlt) projects predominantly to the lateral frontal cortex (areas 12, upper 46, and 9) and to the dorsal aspect of the medial frontal lobe (areas 9 and 10). Only a small number of these fibers terminated within the orbitofrontal cortex. The temporofrontal fibers originating from the middle part of the superior temporal gyrus occupy the lower portion of the extreme capsule and lie just dorsal to the fibers of the uncinate fascicle. The posterior part of the superior temporal gyrus projects to the lateral frontal cortex (area 46, dorsal area 8, and the rostralmost part of dorsal area 6). Some of the fibers from the posterior superior temporal gyrus run initially through the extreme capsule and then cross the claustrum as they ascend to enter the external capsule before continuing their course to the frontal lobe. A larger group of fibers curves round the caudalmost Sylvian fissure and travels to the frontal cortex occupying a position just above and medial to the upper branch of the circular sulcus. This latter pathway constitutes a part of the classically described arcuate fasciculus.

    Full Text Available Although literature advocates the advantages of work force diversification, studies based on the Similarity- Attraction Paradigm indicate that people are more disposed to feel attraction to those who are similar to them. A field study with the comparative data of 89 dyads investigated the effect of the actual and perceived similarity in the quality of the relationship between superiors and subordinates within the Leader-Member Exchange [LMX] perspective. The investigated characteristics were: gender, age and work-family conflict. The data indicate the influence only of perceived similarity in the quality of the relationship between superiors and subordinates. This effect broadens when the subordinate feels satisfied with the quality and frequency of contact with his/her superior. The methodological procedures included factorial analysis and validation of two scales (EIFT and LMX-7, the correlations analysis and hierarchic regressions. Finally, the implications of some results and directions for future research in diversity are discussed.

    The objectives of this study were to determine whether glenoid inclination (1) could be measured accurately on magnetic resonance imaging (MRI) using computed tomography (CT) as a gold standard, (2) could be measured reliably on MRI, and (3) whether it differed between patients with rotator cuff tears and age-matched controls without evidence of rotator cuff tears or glenohumeral osteoarthritis. In this comparative retrospective radiographic study, we measured glenoid inclination on T1 coronal MRI corrected into the plane of the scapula. We determined accuracy by comparison with CT and inter-rater reliability. We compared glenoid inclination between patients with full-thickness rotator cuff tears and patients aged >50 years without evidence of a rotator cuff tear or glenohumeral arthritis. An a priori power analysis determined adequate power to detect a 2° difference in glenoid inclination. (1) In a validation cohort of 37 patients with MRI and CT, the intraclass correlation coefficient was 0.877, with a mean difference of 0° (95% confidence interval, -1° to 1°). (2) For MRI inclination, the inter-rater intraclass correlation coefficient was 0.911. (3) Superior glenoid inclination was 2° higher (range, 1°-4°, P rotator cuff tear group of 192 patients than in the control cohort of 107 patients. Glenoid inclination can be accurately and reliably measured on MRI. Although superior glenoid inclination is statistically greater in those with rotator cuff tears than in patients of similar age without rotator cuff tears or glenohumeral arthritis, the difference is likely below clinical significance.

    Full Text Available This article analyses the dynamic character of relationships between superiors and employees in the context of a psychological contract. One of the assumptions is that superiors and employees’ shared understanding of their mutual obligations and expectations underpins the performance of the psychological contract. The article explains the concept of a psychological contract and addresses possible breaches thereto as well as their impact on the shape of relationships between superiors and employees. Information necessary to carry out the analysis was obtained from surveys conducted with 178 representatives of large and medium-sized firms based in Poland and with 800 of their employees. In addition to determining the state and contents of a psychological contract as felt by superiors and employees, the article provides also a description and the rankings of their mutual expectations and obligations related to a psychological contract. The degree of similarity between the opinions of the surveyed superiors and employees on each other’s obligations and expectations was assessed with a specially constructed index (an opinion coincidence index, OCI. the results of the surveys and the direction and amount of OCI’s deviation from show that while employees and superiors frequently differ in the perceptions of their expectations and obligations, there are also areas where their opinions are identical. It has also been found that employees’ perception of the contents of a psychological contract depends on their age and the number of years they have worked in the organisation. This fact points to the dynamic character of a psychological contract.

    Full Text Available Superior vena cava (SVC syndrome is most commonly the insidious result of decreased vascular flow through the SVC due to malignancy, spontaneous thrombus, infections, and iatrogenic etiologies. Clinical suspicion usually leads to computed tomography to confirm the diagnosis. However, when a patient in respiratory distress requires emergent airway management, travel outside the emergency department is not ideal. With the growing implementation of point-of-care ultrasound (POCUS, clinicians may make critical diagnoses rapidly and safely. We present a case of SVC syndrome due to extensive thrombosis of the deep venous system cephalad to the SVC diagnosed by POCUS. [West J Emerg Med. 2014;15(6:715-718

    Full Text Available Abstract Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress. It is most commonly observed in isolation but can be associated with other cardiovascular abnormalities including atrial septal defect, bicuspid aortic valve, coarctation of aorta, coronary sinus ostial atresia, and cor triatriatum. The presence of PLSVC can render access to the right side of heart challenging via the left subclavian approach, which is a common site of access utilized when placing pacemakers and Swan-Ganz catheters. Incidental notation of a dilated coronary sinus on echocardiography should raise the suspicion of PLSVC. The diagnosis should be confirmed by saline contrast echocardiography.

    This is a prospective study to evaluate the accuracy of clinical predictions related to surgical results in subjects who underwent maxillary superior repositioning without anterior-posterior movement. Surgeons' predictions according to clinical (tooth show at rest and at the maximum smile) and cephalometric evaluation were documented for the amount of maxillary superior repositioning. Overcorrection or undercorrection was documented for every subject 1 year after the operations. Receiver operating characteristic curve test was used to find a cutoff point in prediction errors and to determine positive predictive value (PPV) and negative predictive value. Forty subjects (14 males and 26 females) were studied. Results showed a significant difference between changes in the tooth show at rest and at the maximum smile line before and after surgery. Analysis of the data demonstrated no correlation between the predictive data and the surgical results. The incidence of undercorrection (25%) was more common than overcorrection (7.5%). The cutoff point for errors in predictions was 5 mm for tooth show at rest and 15 mm at the maximum smile. When the amount of the presurgical tooth show at rest was more than 5 mm, 50.5% of clinical predictions did not match the clinical results (PPV), and 75% of clinical predictions showed the same results when the tooth show was less than 5 mm (negative predictive value). When the amount of presurgical tooth shown in the maximum smile line was more than 15 mm, 75% of clinical predictions did not match with clinical results (PPV), and 25% of the predictions had the same results because the tooth show at the maximum smile was lower than 15 mm. Clinical predictions according to the tooth show at rest and at the maximum smile have a poor correlation with clinical results in maxillary superior repositioning for vertical maxillary excess. The risk of errors in predictions increased when the amount of superior repositioning of the maxilla increased

  16. Superior and ICG - is there a good side to this?

    International Nuclear Information System (INIS)

    Jeffrey, S.

    1998-01-01

    The issue of whether the proposed merger between Superior Propane and ICG is in the best interest of the consumer was discussed. Petro-Canada, one of Canada's largest integrated oil and gas companies owns ICG. Norcen, a Canadian producer now owned by Union Pacific Resources, used to own Superior Propane. The merger of the two operations, which was driven by a rush to decrease competition, represents a total Canadian market share of 70 per cent or almost 2.5 billion litres of propane per year. Proponents of the merger argue that increased buying power will mean better prices at the plant gate, which will benefit the consumer. Opponents, on the other hand, argue that with low margins to combat, any savings realized will stay in the hands of the newly merged company. The bright side is that despite a huge market share of the newly merged company, there is still a potential to create small companies which understand their local market and which can provide customers with the kind of service they want

  7. The impact of configural superiority on the processing of spatial information.

    Bratch, Alexander; Barr, Shawn; Bromfield, W Drew; Srinath, Aparna; Zhang, Jack; Gold, Jason M

    2016-09-01

    The impact of context on perception has been well documented for over a century. In some cases, the introduction of context to a set of target features may produce a unified percept, leading to a quicker and more accurate classification; a configural superiority effect (Pomerantz, Sager, & Stoever, 1977). Although this effect has been well characterized in terms of the stimulus features that produce the effect, the specific impact context has on the spatial strategies adopted by observers when making perceptual judgments remains unclear. Here, we sought to address this question by using the methods of response classification and ideal observer analysis. In our main experiment, we used a stimulus set known to produce the configural superiority effect and found that although observers were faster in the presence of context, they were actually less efficient at extracting stimulus information. This surprising result was attributable to the use of a spatial strategy in which observers relied on redundant, noninformative features in the presence of context. A control experiment ruled out the possibility that the mere presence of added context led to these strategic shifts. Our results support previous notions about the nature of the perceptual shifts that are induced by the configural superiority effect. However, they also show that configural processing is more nuanced than originally thought: Although observers may be faster at making judgments when context induces the percept of a configural whole, there appears to be a hidden cost in terms of the efficiency with which information is used.

    Full Text Available The use of shockwave lithotripsy is currently the mainstay of treatment in renal calculosis. Several complications including vessel injuries have been implied to extracorporeal shockwave lithotripsy. We report an isolated dissection of the superior mesenteric artery in a 60-year-old male presenting with abdominal pain which occurred three days after extracorporeal shockwave lithotripsy. The patient was treated conservatively and the abdominal pain subsided 24 hours later. The patient's history, the course of his disease, and the timing may suggest a correlation between the dissection and the ESWL.

  11. Facilitating Effects of Emotion on the Perception of Biological Motion: Evidence for a Happiness Superiority Effect.

    Science.gov (United States)

    Lee, Hannah; Kim, Jejoong

    2017-06-01

    It has been reported that visual perception can be influenced not only by the physical features of a stimulus but also by the emotional valence of the stimulus, even without explicit emotion recognition. Some previous studies reported an anger superiority effect while others found a happiness superiority effect during visual perception. It thus remains unclear as to which emotion is more influential. In the present study, we conducted two experiments using biological motion (BM) stimuli to examine whether emotional valence of the stimuli would affect BM perception; and if so, whether a specific type of emotion is associated with a superiority effect. Point-light walkers with three emotion types (anger, happiness, and neutral) were used, and the threshold to detect BM within noise was measured in Experiment 1. Participants showed higher performance in detecting happy walkers compared with the angry and neutral walkers. Follow-up motion velocity analysis revealed that physical difference among the stimuli was not the main factor causing the effect. The results of the emotion recognition task in Experiment 2 also showed a happiness superiority effect, as in Experiment 1. These results show that emotional valence (happiness) of the stimuli can facilitate the processing of BM.

    A 71-year-old woman presented with a life-threatening thyroid hemorrhage after US-guided chemical parathyroidectomy. The diagnosis was made by angiography followed by immediate embolization of a pseudoaneurysm of the left superior thyroid artery. Embolization controlled the hemorrhage, obviating the need for surgery. The patient made a full recovery with no evidence of further hemorrhage. Pseudoaneurysm of the superior thyroid artery is a rare cause of hemorrhage and percutaneous embolization is an effective method of treatment

    BACKGROUND: Studies have shown that neurogenesis in the dentate gyrus plays an important role in learning and memory. However, studies have not determined whether the superior cervical ganglion or the sympathetic nerve system influences hippocampal neurogenesis or learning and memory in adult rats. OBJECTIVE: To observe differences in dentate gyrus neurogenesis, as well as learning and memory, in adult rats following superior cervical ganglionectomy. DESIGN, TIME AND SETTING: A randomized, controlled, animal study was performed at the Immunohistochemistry Laboratory of the School of Life Sciences in Lanzhou University from July 2006 to July 2007.MATERIALS: Doublecortin polyclonal antibody was provided by Santa Cruz Biotechnology, USA;avidin-biotin-peroxidase complex was purchased from Zhongshan Goldenbride Biotechnology, China;Morris water maze was bought from Taimeng Technology, China. METHODS: A total of 20 adult, male, Wistar rats were randomly divided into surgery and control groups, with 10 rats in each group. In the surgery group, the bilateral superior cervical ganglions were transected. In the control group, the superior cervical ganglions were only exposed, but no ganglionectomy was performed. MAIN OUTCOME MEASURES: To examine distribution, morphology, and number of newborn neurons in the dentate gyrus using doublecortin immunohistochemistry at 36 days following surgical procedures. To examine ability of learning and memory in adult rats using the Morris water maze at 30 days following surgical procedures. RESULTS: Doublecortin immunohistochemical results showed that a reduction in the number of doublecortin-positive neurons in the surgery group compared to the control group (P<0.05), while the distribution of doublecortin-positive neurons was identical in the two groups. The surgery group exhibited significantly worse performance in learning and spatial memory tasks compared to the control group (P<0.05). CONCLUSION: Superior cervical ganglionectomy

    Full Text Available Disorders involving dysfunctional sensory processing are characterized by an inability to filter sensory information, particularly simultaneously arriving multimodal inputs. We examined the effects of prenatal exposure to valproic acid (VPA, a teratogen linked to sensory dysfunction, on the behavior of juvenile and adult rats, and on the anatomy of the superior colliculus, a critical multisensory integration center in the brain. VPA-exposed rats showed deficits in colliculus-dependent behaviors including startle response, prepulse inhibition and nociceptive responses. Some deficits reversed with age. Stereological analyses revealed that colliculi of VPA-treated rats had significantly fewer parvalbumin-positive neurons, a subset of GABAergic cells. These results suggest that prenatal VPA treatment affects the development of the superior colliculus and leads to persistent anatomical changes evidenced by aberrant behavior in tasks that require sensory processing.

    Full Text Available Bidirectional superior cavopulmonary shunt (bidirectional Glenn shunt is generally performed in many congenital cardiac anomalies where complete two ventricle circulations cannot be easily achieved. The advantages of BDG shunt are achieved by partially separating the pulmonary and systemic venous circuits, and include reduced ventricular preload and long-term preservation of myocardium. The benefits of additional pulsatile pulmonary blood flow include the potential growth of pulmonary arteries, possible improvement in arterial oxygen saturation, and possible prevention of development of pulmonary arteriovenous malformations. However, increase in the systemic venous pressure after BDG with additional pulsatile blood flow is known. We describe the peri-operative implications of severe flow reversal in the superior vena cava after pulsatile BDG shunt construction in a child who presented for surgical interruption of the main pulmonary artery.

    The records of 38 patients with superior vena cava syndrome (SVC syndrome) due to malignancy and who received radiation therapy were retrospectively reviewed. The majority were lung cancers, constituting 28 of the 38 cases (73.7%). All patients were treated with conventional radiation doses ranging from 20 to 70 Gy and good symptomatic response was observed in 31 cases (81.6% ). The response appeared within 1.7±0.9 weeks on average (3 days-4 weeks;, and performance status also improved in 50% of the patients. The median survival was 6.6 months. Long term survivors were seen mostly in patients with thymoma, and only one patient ever showed a recurrence of SVC syndrome. We conclude that radiotherapy can be an effective therapeutic modality for SVC syndrome and that it improves the quality of life in most patients. (author)

    The cisco Coregonus artedi was once the most abundant fish species in the Great Lakes, but currently cisco populations are greatly reduced and management agencies are attempting to restore the species throughout the basin. To increase understanding of the spatial scale at which density‐independent and density‐dependent factors influence cisco recruitment dynamics in the Great Lakes, we used a Ricker stock–recruitment model to identify and quantify the appropriate spatial scale for modeling age‐1 cisco recruitment dynamics in Lake Superior. We found that the recruitment variation of ciscoes in Lake Superior was best described by a five‐parameter regional model with separate stock–recruitment relationships for the western, southern, eastern, and northern regions. The spatial scale for modeling was about 260 km (range = 230–290 km). We also found that the density‐independent recruitment rate and the rate of compensatory density dependence varied among regions at different rates. The density‐independent recruitment rate was constant among regions (3.6 age‐1 recruits/spawner), whereas the rate of compensatory density dependence varied 16‐fold among regions (range = −0.2 to −2.9/spawner). Finally, we found that peak recruitment and the spawning stock size that produced peak recruitment varied among regions. Both peak recruitment (0.5–7.1 age‐1 recruits/ha) and the spawning stock size that produced peak recruitment (0.3–5.3 spawners/ha) varied 16‐fold among regions. Our findings support the hypothesis that the factors driving cisco recruitment operate within four different regions of Lake Superior, suggest that large‐scale abiotic factors are more important than small‐scale biotic factors in influencing cisco recruitment, and suggest that fishery managers throughout Lake Superior and the entire Great Lakes basin should address cisco restoration and management efforts on a regional scale in each lake.

    Although it is widely believed that females outperform males in the ability to recognize other people's emotions, this conclusion is not well supported by the extant literature. The current study sought to provide a strong test of the female superiority hypothesis by investigating sex differences in emotion recognition for five basic emotions using stimuli well-calibrated for individual differences assessment, across two expressive domains (face and body), and in a large sample (N = 1,022: Study 1). We also assessed the stability and generalizability of our findings with two independent replication samples (N = 303: Study 2, N = 634: Study 3). In Study 1, we observed that females were superior to males in recognizing facial disgust and sadness. In contrast, males were superior to females in recognizing bodily happiness. The female superiority for recognition of facial disgust was replicated in Studies 2 and 3, and this observation also extended to an independent stimulus set in Study 2. No other sex differences were stable across studies. These findings provide evidence for the presence of sex differences in emotion recognition ability, but show that these differences are modest in magnitude and appear to be limited to facial disgust. We discuss whether this sex difference may reflect human evolutionary imperatives concerning reproductive fitness and child care. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

    To demonstrate the Bereitschaftspotentials (BPs) over the high lateral convexity in the superior frontal gyrus, movement-related cortical potentials with respect to the middle finger extension were recorded in seven patients with refractory epilepsy who underwent subdural implantation of platinum electrode grids and/or strips covering the high lateral frontal convexity. In two out of the seven patients, BPs were recorded from the electrodes placed on the superior frontal gyrus in the vicinity of the border between the medial and lateral frontal lobes, which were distinct from those recorded from the primary sensorimotor cortex. The results suggest the possible contribution of either the lateral dorsal non-primary motor area or the SMA to the generation of the BPs.

    Full Text Available Introduction: Lactobacilli are a group of lactic acid bacteria that their final product of fermentation is lactic acid. The objective of this research is selection of local Lactobacilli producing L (+ lactic acid. Materials and methods: In this research the local strains were screened based on the ability to produce lactic acid. The screening was performed in two stages. The first stage was the titration method and the second stage was the enzymatic method. The superior strains obtained from titration method were selected to do enzymatic test. Finally, the superior strains in the second stage (enzymatic which had the ability to produce L(+ lactic acid were identified by biochemical tests. Then, molecular identification of strains was performed by using 16S rRNA sequencing. Results: In this study, the ability of 79 strains of local Lactobacilli in terms of production of lactic acid was studied. The highest and lowest rates of lactic acid production was 34.8 and 12.4 mg/g. Superior Lactobacilli in terms of production of lactic acid ability of producing had an optical isomer L(+, the highest levels of L(+ lactic acid were with 3.99 and the lowest amount equal to 1.03 mg/g. The biochemical and molecular identification of superior strains showed that strains are Lactobacillus paracasei. Then the sequences of 16S rRNA of superior strains were reported in NCBI with accession numbers KF735654، KF735655، KJ508201and KJ508202. Discussion and conclusion: The amounts of lactic acid production by local Lactobacilli were very different and producing some of these strains on available reports showed more products. The results of this research suggest the use of superior strains of Lactobacilli for production of pure L(+ lactic acid.

    A large body of evidence supports the existence of a robust handedness difference in episodic memory retrieval, with inconsistent-handedness being associated with superior memory across a wide variety of paradigms, including superior retrieval of lab-based and real world memories. Despite superior episidoc memory in inconsistent-handers, and despite neuroanatomical and neurophysiological differences in cortical regions between inconsistent- and consistent-handers, we are aware of no studies to date that have examined physiological activity in the brains of inconsistent- versus consistent-handers while engaged in memory tasks. The purpose of this paper, therefore, is to present a first look at this issue, using functional near-infrared spectroscopy (fNIRS) as a simple, non-invasive measure of frontal lobe activity during encoding and recall of list words in inconsistent- and consistent-handers. Behaviourally, we replicated prior studies, finding a significant inconsistent-handed advantage in free recall. Using fNIRS-derived oxygenated haemoglobin (O 2 Hb) as a measure of frontal lobe activity, we found the first evidence for handedness differences in brain activity that are associated with the handedness differences in episodic retrieval. Specifically, the primary finding was that increased O 2 Hb in the right hemisphere during recall was associated with better retrieval, but for consistent-handers only.

    Objective: To investigate the safety of the placement of Tulip retrievable filter in superior vena cava and to discuss the prevention of pulmonary embolism (PE). Methods: Implantation of Tulip retrievable filter in superior vena cava was performed in ten patients (6 males and 4 females, aged 42-60 years) with acute or subacute deep venous thrombosis in upper extremity or cephalo-cervical region. After the placement of filter, the local via-catheter thrombolysis was conducted. The clinical results, such as the improvement of venous obstructed symptoms at upper extremity or cephalo-cervical region, were recorded. The filter's shape and location were checked. The possible occurrence of pulmonary embolism was observed. Results: The filter was successfully implanted in supper vena cava in all patients, and the deep venous thrombosis at upper extremity and cephalo-cervical region responded well to the local via-catheter thrombolysis. The filters showed no displacement or tilting. The swelling at upper extremity and cephalo-cervical region was markedly faded away. No symptomatic pulmonary embolism occurred. the filter was successfully retrieved via the femoral vein in four patients. Conclusion: Tulip filter can be safety implanted in superior vena cava and can be smoothly retrieved. The occurrence of pulmonary embolism can be effectively prevented if corresponding local via-catheter thrombolysis is carried out. (authors)

    The superior cervical sympathetic ganglion, the largest and most cranial of the three cervical sympathetic ganglia, transfers sympathetic signals to specific targets on the head and neck. This ganglion is located just lateral to the retropharyngeal space along the medial margin of the carotid sheath. Located thus, an enlarged superior cervical sympathetic ganglion can mimic a metastatic lymph node in the retropharyngeal space of the suprahyoid neck in head and neck cancer patients. However, this is often disregarded by radiologists due to lack of interest in its anatomic location. We present a case of an enlarged superior cervical sympathetic ganglion mimicking a retropharyngeal metastatic lymph node in a 42-year-old man with oral tongue cancer.

    Objective: The aim of this study was to evaluate the prevalence of 'high-riding' superior pericardial recess (HRSPR) on thin-section (1 mm) 16-multidetector computed tomography (MDCT) scans. Materials and methods: Three hundred and fourteen consecutive chest CT scans obtained with a thin-section 16 MDCT were retrospectively evaluated. The prevalence and characteristic of HRSPR were analyzed. Results: HRSPR was depicted in 21 patients (11 men and 10 women) (6.6%) who ranged in age from 28 to 72 years (mean age, 57 years). The extended recesses were rounded/oval shaped in five patients and triangular, spindle, half moon or irregular shaped in the other 16 patients. Conclusion: Our data suggest as HRSPRs are more frequently and better depicted on thinsection MDCT scans, and this improves the capability to distinguish this superior extension of the superior aortic recess from abnormal findings such as lymphadenopathy, cystic lesions, and aortic dissection.

    Anecdotally, it has been reported that individuals with acquired prosopagnosia compensate for their inability to recognize faces by using other person identity cues such as hair, gait or the voice. Are they therefore superior at the use of non-face cues, specifically voices, to person identity? Here, we empirically measure person and object identity recognition in a patient with acquired prosopagnosia and object agnosia. We quantify person identity (face and voice) and object identity (car and horn) recognition for visual, auditory, and bimodal (visual and auditory) stimuli. The patient is unable to recognize faces or cars, consistent with his prosopagnosia and object agnosia, respectively. He is perfectly able to recognize people's voices and car horns and bimodal stimuli. These data show a reverse shift in the typical weighting of visual over auditory information for audiovisual stimuli in a compromised visual recognition system. Moreover, the patient shows selectively superior voice recognition compared to the controls revealing that two different stimulus domains, persons and objects, may not be equally affected by sensory adaptation effects. This also implies that person and object identity recognition are processed in separate pathways. These data demonstrate that an individual with acquired prosopagnosia and object agnosia can compensate for the visual impairment and become quite skilled at using spared aspects of sensory processing. In the case of acquired prosopagnosia it is advantageous to develop a superior use of voices for person identity recognition in everyday life. Copyright © 2010 Elsevier Ltd. All rights reserved.

    A weak central coherence theory in autism spectrum disorder (ASD) proposes that a cognitive bias toward local processing in ASD derives from a weakness in integrating local elements into a coherent whole. Using this theory, we hypothesized that shape perception through active touch, which requires sequential integration of sensorimotor traces of exploratory finger movements into a shape representation, would be impaired in ASD. Contrary to our expectation, adults with ASD showed superior performance in a haptic-to-visual delayed shape-matching task compared to adults without ASD. Accuracy in discriminating haptic lengths or haptic orientations, which lies within the somatosensory modality, did not differ between adults with ASD and adults without ASD. Moreover, this superior ability in inter-modal haptic-to-visual shape matching was not explained by the score in a unimodal visuospatial rotation task. These results suggest that individuals with ASD are not impaired in integrating sensorimotor traces into a global visual shape and that their multimodal shape representations and haptic-to-visual information transfer are more accurate than those of individuals without ASD.

    How the brain extracts words from auditory signals is an unanswered question. We recorded approximately 150 single and multi-units from the left anterior superior temporal gyrus of a patient during multiple auditory experiments. Against low background activity, 45% of units robustly fired to particular spoken words with little or no response to pure tones, noise-vocoded speech, or environmental sounds. Many units were tuned to complex but specific sets of phonemes, which were influenced by local context but invariant to speaker, and suppressed during self-produced speech. The firing of several units to specific visual letters was correlated with their response to the corresponding auditory phonemes, providing the first direct neural evidence for phonological recoding during reading. Maximal decoding of individual phonemes and words identities was attained using firing rates from approximately 5 neurons within 200 ms after word onset. Thus, neurons in human superior temporal gyrus use sparse spatially organized population encoding of complex acoustic-phonetic features to help recognize auditory and visual words. © The Author 2013.

    Persistent left superior vena cava (PLSVC) is a congenital anomaly, that results when there is an absence of the normal regression of the left common precardinal vein during embryogenesis. Usually, this anomaly remains asymptomatic, however, when the PLSVC drains into the left atrium this could lead to a right-to-left shunt. Additionally, this can result in inadvertent delivery of air or thrombus into the systemic circulation with potential neurologic, cardiac and renal complications. In this article, we present a case of an extreme premature Mexican newborn in which the diagnosis was made after placement of a percutaneous central venues catheter.

    2013-01-01

    The advent of affordable Next Generation Sequencing technologies has had major impact on studies of many crop species, where access to genomic technologies and genome-scale data sets has been extremely limited until now. The recent development of genomic resources in blueberry will enable the application of high throughput gene expression approaches that should relatively quickly increase our understanding of blueberry physiology. These studies, however, require a highly accurate and robust workflow and make necessary the identification of reference genes with high expression stability for correct target gene normalization. To create a set of superior reference genes for blueberry expression analyses, we mined a publicly available transcriptome data set from blueberry for orthologs to a set of Arabidopsis genes that showed the most stable expression in a developmental series. In total, the expression stability of 13 putative reference genes was evaluated by qPCR and a set of new references with high stability values across a developmental series in fruits and floral buds of blueberry were identified. We also demonstrated the need to use at least two, preferably three, reference genes to avoid inconsistencies in results, even when superior reference genes are used. The new references identified here provide a valuable resource for accurate normalization of gene expression in Vaccinium spp. and may be useful for other members of the Ericaceae family as well.

    Full Text Available Background. The uncoordinated activity of the superior and inferior parts of the lateral pterygoid muscle (LPM has been suggested to be one of the causes of temporomandibular joint (TMJ disc displacement. A therapy for this muscle disorder is the injection of botulinum toxin (BTX, of the LPM. However, there is a potential risk of side effects with the injection guide methods currently available. In addition, they do not permit appropriate differentiation between the two bellies of the muscle. Herein, a novel method is presented to provide intraoral access to the superior head of the human LPM with maximal control and minimal hazards. Methods. Computational tomography along with digital imaging software programs and rapid prototyping techniques were used to create a rapid prototyped guide to orient BTX injections in the superior LPM. Results. The method proved to be feasible and reliable. Furthermore, when tested in one volunteer it allowed precise access to the upper head of LPM, without producing side effects. Conclusions. The prototyped guide presented in this paper is a novel tool that provides intraoral access to the superior head of the LPM. Further studies will be necessary to test the efficacy and validate this method in a larger cohort of subjects.

    To demonstrate that tibial intraneural ganglia in the popliteal fossa are derived from the posterior portion of the superior tibiofibular joint, in a mechanism similar to that of peroneal intraneural ganglia, which have recently been shown to arise from the anterior portion of the same joint. Retrospective clinical study and prospective anatomic study. The clinical records and MRI findings of three patients with tibial intraneural ganglion cysts were analyzed and compared with those of one patient with a tibial extraneural ganglion cyst and one volunteer. Seven cadaveric limbs were dissected to define the articular anatomy of the posterior aspect of the superior tibiofibular joint. The condition of the three patients with intraneural ganglia recurred because their joint connections were not identified initially. In two patients there was no cyst recurrence when the joint connection was treated at revision surgery; the third patient did not wish to undergo additional surgery. The one patient with an extraneural ganglion had the joint connection identified at initial assessment and had successful surgery addressing the cyst and the joint connection. Retrospective evaluation of the tibial intraneural ganglion cysts revealed stereotypic features, which allowed their accurate diagnosis and distinction from extraneural cases. The intraneural cysts had tubular (rather than globular) appearances. They derived from the postero-inferior portion of the superior tibiofibular joint and followed the expected course of the articular branch on the posterior surface of the popliteus muscle. The cysts then extended intra-epineurially into the parent tibial nerves, where they contained displaced nerve fascicles. The extraneural cyst extrinsically compressed the tibial nerve but did not directly involve it. All cadaveric specimens demonstrated a small single articular branch, which derived from the tibial nerve to the popliteus. The branch coursed obliquely across the posterior

    In five patients with substernal goiter, three of whom presented with superior vena cava (SVC) syndrome, and in five normal subjects, radionuclide superior cavography (RNSC) was performed with extension and flexion of the neck during tracer administration (simultaneous bilateral injection of Tc- 99 m pertechnetate). When the tracer was injected during neck extension, venous flow pattern was abnormal in four of five patients, and transit time (TT) prolonged in three of five patients. In this posture, mean TT +/- 1 standard deviation (SD) was 6.3 +/- 2.6 s (range 3.5 to 9 s) for the five patients and 3.5 +/- 0.7 s (range 2.5 to 4.5 s) for a group of five control subjects. When the tracer was injected during neck flexion, all five patients showed abnormal flow patterns and prolonged TT (mean +/- 1 SD 10.1 +/- 4.1 s; range 4.4 to 16 s), in contrast to the control group where a slight decrease in TT was found (mean +/- 1 SD 3 +/- 0.6 s; range 2 to 3.5 s). In the presence of a substernal goiter, or any mobile mass at the thoracic inlet, impairment of venous flow through the SVC system appears to be a common occurrence, readily detectable by RNSC. RNSC should be performed with neck flexion during tracer injection, since in this posture its ability to detect compromised venous flow through the SVC system is enhanced, even in patients without a clinically apparent SVC syndrome

    62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival.

    Full Text Available Obstruction of blood flow in the superior vena cava (SVC results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung, lymph nodes, and other mediastinal structures, or by thrombosis of blood within the SVC. Occasionally, both mechanisms co-exist. We hereby report a case of a 28-year-old male, Saudi patient who was diagnosed with end-stage renal disease and was maintained on regular hemodiaysis via right jugular vein dual lumen catheter for ten months. Three years later, the patient presented with signs and symptoms suggestive of SVC obstruction that was successfully managed with SVC stenting.

  20. Management of type II superior labrum anterior posterior lesions: a review of the literature

    2010-02-01

    Full Text Available Superior labrum anterior and posterior lesions were first described in 1985 by Andrews et al. and later classified into four types by Synder et al. The most prevalent is type II which is fraying of the superior glenoid labrum with detachment of the biceps anchor. Superior labrum anterior posterior (SLAP lesions can also be associated with other shoulder pathology. Both MRI and MRA can be utilized in making the diagnosis with the coronal images being the most sensitive. The mechanism of injury can be either repetitive stress or acute trauma with the superior labrum most vulnerable to injury during the late cocking phase of throwing. A combination of the modified dynamic labral shear and O’Brien test can be used clinically in making the diagnosis of SLAP lesion. However, the most sensitive and specific test used to diagnosis specifically a type II SLAP lesion is the Biceps Load Test II. The management of type II SLAP lesions is controversial and dependent on patient characteristics. In the young high demanding overhead athlete, repair of the type II lesion is recommended to prevent glenohumeral instability. In middle-aged patients (age 25-45, repair of the type II SLAP lesion with concomitant treatment of other shoulder pathology resulted in better functional outcomes and patient satisfaction. Furthermore, patients who had a distinct traumatic event resulting in the type II SLAP tear did better functionally than patients who did not have the traumatic event when the lesion was repaired. In the older patient population (age over 45 years, minimum intervention (debridement, biceps tenodesis/tenotomy to the type II SLAP lesion results in excellent patient satisfaction and outcomes.
