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.

Full Text Available Recibido 27 de octubre de 2009 • Aceptado 02 de diciembre de 2009 • Corregido 05 de marzo de 2010       Para pensar en una propuesta educativa que enseñe a aprender, es necesario pensar en un cambio no sólo en lo educativo, sino, también, en lo político, económico, social, ecológico y cultural, entre otros; que permita una comprensión de la realidad y es aquí donde la construcción del conocimiento y el rol de las ciencias tienen un papel fundamental. Pero no debemos olvidar que el desarrollo de la ciencia ha estado marcado por la llamada ciencia positivista, la cual se caracteriza por interpretar los fenómenos y la forma cómo funcionan éstos por medio de teorías y leyes, en los que el contexto y el ser humano tienen un papel protagónico muy pobre, por no decir ninguno; a esto se le puede llamar el cientificismo, que ha permitido un desarrollo, incluso, sobre de las necesidades humanas. Pero, desde los 90s, se da un resurgimiento paulatino del humanismo en los campos educativos y se busca trabajar en la revalorización de lo humano, lo cual implica una serie de cambios en el plano epistemológico y metodológico que nos impulsa hacia nuevas formas de trabajar. Esto nos llama a reflexionar en alternativas trascendentales para la construcción del conocimiento, que superen la enseñanza tradicional de las ciencias, que sean amplias, sistemáticas, flexibles y enmarcadas en una cultura humanista. Algunos modelos de las nuevas tendencias son: investigación dirigida, aprendizaje por descubrimiento, aprendizaje por indagación y la enseñanza de las ciencias y las nuevas tecnologías.

Shen: una psicología holística de la medicina china tradicional

Yidy Páez Casadiegos

2015-01-01

Full Text Available La palabra Shen denota mente, consciencia, estados mentales, pero debido a su carácter ideo-pictográfico, connota un nivel de metáfora que convierte su traducción en un ejercicio hermenéutico, sobre todo cuando hace parte de un estilo de pensamiento que se estructura discursiva y poéticamente con otras palabras-metáfora. La metáfora principal del sistema es Tai-Chi (“gran respiración celeste”, “la gran energía cósmica”, la “energía del todo”, etc., a partir de la cual se construye un discurso médico-ético-filosófico. La palabra Shen se refiere a un tipo de “energía” ( chi que permite interpretar de manera holística los mecanismos generadores de síntomas, la descripción de sus signos, sus abordajes terapéuticos, y la condición ética del tera - peuta en la relación médico-paciente. A través del Shen se integran de manera transdisciplinaria las esferas del Tai-Chi natural, con un tai-chi mental-político-societal. A partir de estas consideraciones, se propone la medicina tradicional china como una medicina-psicológica , por su propedéutica y metodología holística, y por su visión psico- somática, en sentido epistemológico. Esta medicina-psicológica suscita preguntas frente a nuestras convenciones institucionales y seguridades discursivas de una “psicología médica” que se percibe, cada vez más, separada disciplinariamente del saber psicológico.

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

Full Text Available A persistência de veia cava superior esquerda com ausência da veia cava superior é uma anomalia rara, principalmente quando associada a bloqueio atrioventricular de 3º grau. 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.

Writing superiority in cued recall

Carina eFueller

2013-10-01

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

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)

2002-06-01

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.

PROCEDIMENTOS METODOLÓGICOS: Estudo de caso qualitativo realizado em uma comunidade tradicional de terreiro na cidade de Porto Alegre (RS, entre 2007 e 2008. Foram participantes o sacerdote/Babalorixá e seis adeptos do terreiro. Para a coleta dos dados e construção do corpus de análise, foram realizadas entrevistas abertas, gravadas e transcritas. A categorização dos depoimentos, a partir do enfoque sistêmico complexo, possibilitou a construção de dois eixos temáticos: 1 terreiro e concepção de saúde e 2 origem do sofrimento psíquico e identidade cultural. ANÁLISE DOS RESULTADOS: Na comunidade de terreiro, as terapêuticas tradicionais em saúde, como o uso de ervas, banhos, dietas e/ou ritos de iniciação foram associados a terapêuticas convencionais propostas pelo Sistema Único de Saúde. Consideram em sua concepção etiológica do sofrimento psíquico e em sua concepção de saúde os vínculos e a pertença a um território, as relações entre os sujeitos e a relação entre suas dimensões física, psíquica e espiritual. CONCLUSÕES: O modo de compreender e agir no mundo, vivido no terreiro, com seus mitos e ritos, crenças e valores, constitui um conjunto de saberes legítimos em seu contexto que, muitas vezes, se contrapõe e escapa aos saberes e verdades técnico-científicas dos profissionais.

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

Superior Mesenteric Artery Syndrome: An Infrequent Complication of Scoliosis Surgery

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.

[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.

Biomechanical Effects of Acromioplasty on Superior Capsule Reconstruction for Irreparable Supraspinatus Tendon Tears.

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

El reverso de la ciudadanía tradicional: la centralidad desentrañada

Full Text Available El presente artículo aborda la emergencia de ciudadanías configuradas en el desentrañamiento, toda vez que se rehúsan a la asociatividad tradicional, basada en los derechos jurídico-legales y en la membresía política anclada a la soberanía estatal. Para ello, se analiza el reverso de la noción de ciudadanía planteada por T. H. Marshall, mostrando que bajo el principio de igualdad ante la ley anida la paradoja de la inclusión-exclusión, cuyo resultado es la desigualdad. Esta contradicción se explora a partir de la categoría de nomadismo contemporáneo, construida desde la perspectiva de la teoría poscolonial, que coloca en el centro, temáticas que habían sido arrojadas a las márgenes de lo instituido, tales como la reunión en el borde de culturas, fronteras y memorias. Para lograr tal acercamiento, se propone una perspectiva que dialogue con la tradición racionalista centrada en el hombre universal, pero, también, con el reconocimiento de la diferencia.This article discusses the emergence of citizenship, configured in the uprooting, since they refuse to traditional partnerships, based on legal rights, and in the political membership anchored to state sovereignty. To do this, we analyze the back of the notion of citizenship proposed by T. H. Marshall, showing that under the principle of equality under the law nests the paradox of inclusion-exclusion, resulting in inequality. This contradiction is explored based on the category of contemporary nomadism, built from the perspective of postcolonial theory, which placed in the center, subjects that had been thrown to the margins of the instituted, such as the gathering at the edge of cultures, borders and memories. To achieve this approach, we propose a perspective that speaks to the rationalist tradition centered on the universal man, but also the recognition of difference.

The picture superiority effect in associative recognition.

Science.gov (United States)

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.)

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

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.

Aneurysm of the superior mesenteric artery

Energy Technology Data Exchange (ETDEWEB)

Gebauer, A

1984-11-01

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.

Superior mesenteric artery compression syndrome - case report

Paulo Rocha França Neto

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.

Aging and the picture superiority effect in recall.

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.

Noise management to achieve superiority in quantum information systems.

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).

Jou, Roger J; Minshew, Nancy J; Keshavan, Matcheri S; Vitale, Matthew P; Hardan, Antonio Y

2010-11-11

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.

Superior refining performance beyond 2000 -- Breaking traditional paradigms

International Nuclear Information System (INIS)

Tassel, B. van

1995-01-01

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. Given the herd mentality of the oil industry, superior performers must take decisive, preemptive action to generate a substantial, competitive advantage

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 Para la recolección y análisis de la información se utilizaron la Etnografía focalizada y la técnica de Spradley y la teoría de la diversidad y la universalidad de los cuidados culturales de Leininger se tomó como referente teórico. Su objetivo fue describir los cuidados que brindaban las parteras tradicionales a partir de creencias y prácticas en las mujeres durante el parto en la zona rural de la región del valle del río Cimitarra, Magdalena Medio. El estudio se desarrolló en el valle del río Cimitarra y la ciudad de Barrancabermeja. Participaron siete parteras tradicionales y se recolectaron los datos mediante entrevista etnográfica y observación participante entre los años 2007 y 2008. El tema central es " El saber de la partera tradicional del valle del río Cimitarra: cuidando la vida" y cinco dominios culturales: alistarse para la atención del mismo, identificar el momento del parto, ayudar a la mujer a parir, proteger al bebé después del nacimiento y proteger a la mujer después del nacimiento. Cuidar la vida se relaciona con la necesidad de " sobrevivir" a pesar de la guerra, la violencia y el abandono estatal. Las acciones de cuidado se fundan en creencias culturales, la cotidianidad del trabajo del campo, la tradición oral y la invocación divina en medio del complejo contexto ambiental, la incertidumbre del conocmiento y el miedo a problemas legales.

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�

Vena cava superior syndrome associated with sarcoidosis

Wurm, K.; Walz, M.; Reidemeister, J.C.; Donhuijsen, K.

1988-01-01

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

Designing Pareto-superior demand-response rate options

International Nuclear Information System (INIS)

Horowitz, I.; Woo, C.K.

2006-01-01

We explore three voluntary service options-real-time pricing, time-of-use pricing, and curtailable/interruptible service-that a local distribution company might offer its customers in order to encourage them to alter their electricity usage in response to changes in the electricity-spot-market price. These options are simple and practical, and make minimal information demands. We show that each of the options is Pareto-superior ex ante, in that it benefits both the participants and the company offering it, while not affecting the non-participants. The options are shown to be Pareto-superior ex post as well, except under certain exceptional circumstances. (author)

Temporal Bone Fracture Causing Superior Semicircular Canal Dehiscence

Directory of Open Access Journals (Sweden)

Kevin A. Peng

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.

Spatial vision is superior in musicians when memory plays a role.

Science.gov (United States)

Weiss, Atalia H; Biron, Tali; Lieder, Itay; Granot, Roni Y; Ahissar, Merav

2014-08-21

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.

Total variation superiorized conjugate gradient method for image reconstruction

Science.gov (United States)

Zibetti, Marcelo V. W.; Lin, Chuan; Herman, Gabor T.

2018-03-01

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.

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

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

O que existem são grupos humanos que por apresentarem algumas características gerais, podem ser denominadas como “tradicionais”. O presente artigo pretende apresentar discussões e debates acerca do conceito de população tradicional e sua importância para as questões ambientais da atualidade. A construção do sentido e do significado desse conceito liga-se historicamente ao socioambientalismo dos extrativistas da borracha do estado do Acre e, posteriormente, a outros povos da floresta amazônica. O fulcro conceitual dessas populações reside no sentido dado as suas ações econômicas, culturais, simbólicas etc. calcadas na sustentabilidade ambiental. Para a consecução do objetivo deste trabalho, buscou-se fundamentar as argüições em pesquisa bibliográfica realizada em biblioteca virtual e física, assim como em acervo pessoal. O que segue são aprofundamentos acerca da temática levantada sobre o conceito e a importância dessas populações para o século XXI.

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

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.

Full Text Available Este artigo analisa a influência das empresas clientes na organização do trabalho de seus fornecedores em duas cadeias de suprimentos da indústria automobilística, uma comandada por uma planta modular e outra organizada num arranjo tradicional. Na cadeia tradicional, são examinadas as formas de organização do trabalho de uma fábrica de motores e de dez de seus fornecedores diretos. No caso da planta modular, produtora de caminhões e ônibus, examina-se a organização do trabalho no sistema modular como um todo, explorando-se as peculiaridades deste tipo de arranjo. Os resultados da pesquisa apontam que, na planta modular, a influência da montadora sobre a organização do trabalho configura-se de forma mais direta com relação a salários e jornada de trabalho. Na cadeia tradicional, a influência ocorre de forma indireta, por meio de exigências voltadas para outras áreas de gestão.This paper analyzes the influence that buyer firms have on their suppliers' work organization in two supply chains in the automotive industry. One of the supply chains is controlled by a modular plant and the other is organized in the traditional way. In the traditional supply chain, the work organization of an engine manufacturer plant as well as of ten of its suppliers is examined. In the modular plant, a truck and bus manufacturer, the work organization of the whole modular system is examined, exploring the peculiarities of this kind of arrangement. The results of the research shows that in the modular plant the assembler's influence over the work organization, relating to aspects like wages and work time, is more direct. In the traditional supply chain, the influence happens in a indirect way, through requirements done to other areas of management.

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 The aim of this study was to examine levator palpebralis superior muscle histologically in patients with congenital blepharoptosis and to investigate the relationship between these findings and age, sex and degree of blefaroptosis in this patient group.Materials and methods: Levator muscle of 13 patients with congenital ptosis, who had applied to Dicle University Medical Faculty Ophthalmology Clinic and had undergone levator palpebralis superior muscle resection between january 2009-january 2010, has been examined histopathologically in Histology and Embriology Deparment. During preoperative period, ptosis amount, levator function (LF, tear functions, Bell’s phenomenon and jaw-winking phenomenon were evaluated. All patients underwent resection of levator palpebralis superior muscle. Received postoperative levator muscle was examined by light microscopy.Results: The average age of 9 (69.2% male and 4 (30.8% female cases were 10.61 ± 4.77 (4- 19 years. In histological examination, the quality and quantity of the levator muscle fibrils have been assessed. There was no relationship detected between histological features of levator palpebralis superior muscle and patient’s age and gender (p>0.05. Patients with weak levator palpebralis superior muscle were detected to have fatty degeneration histologically. The higher the levator palpebralis superior muscle function revealed decreased fatty degeneration and increased skeletal muscle fibrils.Conclusion: More ultrastructural studies in larger populations are needed to support the relationship between structure and function of levator palpebralis superior muscle in patients with congenital blepharoptosis.

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.

Full Text Available Sagittaria macrophylla y S. latifolia son plantas acuáticas emergentes que crecen en las orillas y zonas poco profundas de los cuerpos de agua limpios y de poca corriente. La primera es endémica de México, su distribución se restringe a la región del río Lerma y valle de México y está en peligro de extinción. Sagittarial latifolia se distribuye desde Canadá hasta el noroeste de Sudamérica. En México se localiza al menos en 11 estados. El análisis de la distribución de ambas especies muestra una disminución en el Estado de México; los factores que aparentemente están contribuyendo a este fenómeno son, en general, la explosión demográfica, la pérdida del hábitat y la sobreexplotación. No había registros del uso de S. latifolia en México, actualmente se reconoce que sus tubérculos o ‘papas de agua’ tienen importancia económica en la región del río Lerma. El uso tradicional de ambas especies indica que podrían ser una alternativa más en la dieta humana y animal.

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.

Nongovernmental organizations and cooperatives have had an important role in raising financial resources, being involved with advocacy of local communities and advancing legislation changes. But strict best manufacturing practices regulations imposed by the Brazilian National Health Surveillance Agency on the requirements for approval and commercialization of drugs based on herbal medicine products call for the involvement of strong public research institutes capable of supporting community-based pharmacies. Thus, public research institutes are pivotal as they can conduct scientific research studies to evidence the efficacy of herbal medicine products and help building the capacity of local communities to comply with current regulations.El artículo señala el papel desempeñado por institutos públicos de investigación en Brasil en la promoción de la inclusión socioeconómica de comunidades locales por medio del uso del conocimiento tradicional y de la medicina popular.

(Mis)placed central venous catheter in the left superior intercostal vein

Padovan, Ranka Stern; Paar, Maja Hrabak; Aurer, Igor

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.

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.

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.

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 JUSTIFICATIVA E OBJETIVOS: A persistência da veia cava superior esquerda ocorre isoladamente em 0,5% da população normal, porém nos pacientes com cardiopatia congênita chega a estar presente em 3% a 10% dos casos. O objetivo deste relato foi apresentar um caso de diagnóstico intraoperatório com o auxílio da ecocardiografia transesofágica e ressaltar a importância da sua utilização rotineira em intervenções cirúrgicas para correção de cardiopatia congênita. RELATO DO CASO: Paciente do sexo masculino, 16 anos, ASA II, com diagnóstico prévio de comunicação interatrial (CIA tipo seio venoso superior com drenagem anômala parcial de veias pulmonares em programação para correção cirúrgica da cardiopatia. Após indução da anestesia geral foi realizado ecocardiograma transesofágico (ETE. O exame inicial mostrou dilatação das câmaras cardíacas direitas, CIA tipo seio venoso superior de 17 milímetros, drenagem anômala da veia pulmonar superior direita desembocando na veia cava superior (VCS direita e dilatação do seio coronário, o que aventou a possibilidade da persistência da veia cava superior esquerda. Para a confirmação da suspeita foram injetados no acesso venoso do braço esquerdo 10 mL de solução fisiológica a 0,9% (faz o papel de "contraste" no exame ecocardiográfico e imediatamente após foram visualizadas as microbolhas passando pelo seio coronário, teste positivo para o diagnóstico de VCS superior esquerda persistente. CONCLUSÕES: A ecocardiografia transesofágica rotineira no intraoperatório de pacientes com cardiopatia congênita tem fundamental importância como método auxiliar não só ao cirurgião, muitas vezes influenciando diretamente na técnica cirúrgica empregada, como também para o anestesiologista, que pode extrair do exame uma série de informações úteis no manuseio hemodinâmico do paciente.JUSTIFICATIVA Y OBJETIVOS: La persistencia de la vena cava superior izquierda ocurre

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

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.

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.

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 in superior semicircular canal dehiscence syndrome.

Basura, Gregory J; Cronin, Scott J; Heidenreich, Katherine D

2014-03-18

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.

Anthropogenic climate change has altered primary productivity in Lake Superior.

O'Beirne, M D; Werne, J P; Hecky, R E; Johnson, T C; Katsev, S; Reavie, E D

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.

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.

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.

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.

Magnetic resonance imaging in congenital superior oblique palsy

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.)

Foram entrevistados 22 pescadores para a elaboração da lista livre de plantas. Para a análise da lista, foram utilizados: índice de saliência de Smith, análise de consenso cultural, similaridade e dissimilaridade com escalonamento multidimensional e técnica de empilhamento. O programa ANTHROPAC 4.0 foi utilizado para o tratamento estatístico dos dados. Por meio do índice de saliência de Smith, foram identificadas seis rupturas no domínio cultural sobre plantas cultivadas, concentrando-se em 116 etnoespécies. Laranja e milho foram citados com maior frequência e em primeiro lugar na lista, portanto, encontram-se na primeira ruptura da lista livre com índices de Smith 0,728 e 0,711, respectivamente. A análise de consenso cultural mostrou que o CET sobre plantas cultivadas caracteriza um consenso, concentrando-se em 18 etnoespécies. A análise de empilhamento evidenciou que o conhecimento sobre plantas está relacionado aos diferentes tipos de uso. Neste contexto, as possibilidades de uso e manejo aqui evidenciadas podem contribuir para a elaboração de políticas públicas destinadas à conservação da biodiversidade ecológica e cultural.

Status of the shortjaw cisco (Coregonus zenithicus) in Lake Superior

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.

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.

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.

Superior pre-attentive auditory processing in musicians.

Science.gov (United States)

Koelsch, S; Schröger, E; Tervaniemi, M

1999-04-26

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.

2012-04-01

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.

2015-10-01

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.

Superior cervical gangliectomy induces non-exudative age-related macular degeneration in mice

2018-02-01

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

Full Text Available Objetivo: Evaluar y comparar la percepción que del ambiente educativo tienen los estudiantes de medicina de dos universidades iberoamericanas: Universidad de Chile (UCH y Universidad Nacional de Cuyo (UNC, que desarrollan un currículo tradicional y un currículo basado en problemas, respectivamente. Sujetos y métodos: Participaron 465 estudiantes: 232 de la UCH y 233 de la UNC. La distribución fue de 84 y 70 estudiantes para el primer curso, 77 y 97 para el tercero, y 71 y 66 para el quinto, respectivamente. Se aplicó el cuestionario DREEM, que consiste en 50 ítems, agrupados en cinco dimensiones: percepción de la enseñanza, percepción de los profesores, autopercepción académica, percepción de la atmósfera educativa y autopercepción social. Resultados: Las puntuaciones totales fueron mayores en los tres cursos de la UNC. Resultaron similares en todos los cursos de ambas universidades, excepto en el quinto curso de la UCH. Respecto a la percepción acerca de los profesores, los estudiantes de quinto curso de la UCH mostraron las puntuaciones más bajas, mientras que los estudiantes del primer curso de la UNC tuvieron la mejor percepción. Resultados similares se obtuvieron en la autopercepción académica. La percepción del ambiente de aprendizaje fue mejor en la UNC y la autopercepción social tuvo puntuaciones similares en todos los cursos de ambas universidades. Conclusiones: Las diferencias observadas entre ambas universidades podrían atribuirse a sus diferentes currículos. El currículo basado en problemas parece ser mejor valorado que el tradicional. Nuestro estudio corrobora la eficacia del cuestionario DREEM para identificar fortalezas y debilidades del currículo y para evaluar la calidad de la enseñanza en facultades de medicina.

Subjective qualities of memories associated with the picture superiority effect in schizophrenia.

Huron, Caroline; Danion, Jean-Marie; Rizzo, Lydia; Killofer, Valérie; Damiens, Annabelle

2003-02-01

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.

Persistency of the left superior caval vein. Diagnosis and its prenatal importance

International Nuclear Information System (INIS)

Jaramillo, Juan F; Estrada Perea, Mercy H; Muriel, Yina Y

2010-01-01

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.

La macdonalización de la educación superior

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

A Layer-specific Corticofugal Input to the Mouse Superior Colliculus.

Science.gov (United States)

Zurita, Hector; Rock, Crystal; Perkins, Jessica; Apicella, Alfonso Junior

2017-07-05

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.

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.

Savage, Ruth A; Becker, Stefanie I; Lipp, Ottmar V

2016-01-01

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

Picture superiority in free recall: the effects of normal aging and primary degenerative dementia.

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.

The picture superiority effect in conceptual implicit memory: a conceptual distinctiveness hypothesis.

Science.gov (United States)

Hamilton, Maryellen; Geraci, Lisa

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.

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.

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.

Full Text Available This research advances in the attempt to recover the traditional technique of stucco by fire; paradigm of indoor decoration until half of 20th century due to its high quality marbled imitations. On its implementation process, it was used lime mortars with marble aggregates, mineral pigments and greases. With these materials, masses were prepared and extended into the walls, they were painted in fresco and ended with the passage of a heated metal tool. As with any other technique, the time passing over has blurred the knowledge on the subject, making very difficult the preservation or restoration of examples in our heritage. Despite of the limited literature, the process has been recovered; subjecting the samples prepared at different trials that have characterized the finished, both in its merits and its conferred characteristics by finally protecting the samples with a layer of wax, as was done traditionally.Esta investigación avanza en el intento de recuperar la técnica tradicional del estuco a fuego, paradigma de la decoración de espacios interiores hasta la mitad del s. XX por sus imitaciones marmóreas de gran calidad.

Como sucede con otras técnicas, el paso del tiempo ha difuminado los conocimientos sobre la materia, haciendo muy difícil la conservación o restauración de los ejemplos en nuestro patrimonio. A partir de la escasa bibliografía existente se ha recuperado el proceso, sometiendo las muestras elaboradas a diferentes ensayos que han caracterizado el acabado final, tanto en sus características intrínsecas como en las que le son conferidas al proteger finalmente las muestras con una capa de cera, tal y como se realizaba tradicionalmente.

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.

Lima, Breno da Rocha; Perry, Julian D

2013-01-01

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.

Audiovisual speech integration in the superior temporal region is dysfunctional in dyslexia.

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.

Inaoka, Tsutomu; Takahashi, Koji; Ono, Hidetoshi

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.

Don’t words come easy?A psychophysical exploration of word superiority

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.

A Cognitive Assessment of Highly Superior Autobiographical Memory

LePort, Aurora K.R.; Stark, Shauna M.; McGaugh, James L.; Stark, Craig E.L.

2017-01-01

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

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.

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.

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.

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.)

Full Text Available Se presentan de manera cuantitativa y se analizan críticamente los cambios acaecidos en las infraestructuras tradicionales de dos comunidades indígenas Kukama tras la ejecución del programa regional denominado “techo digno”, ejecutado del 2011 al 2014 en la zona rural de la región Loreto. Los datos han sido extraídos de una serie de encuestas analíticas realizadas en las comunidades de San Jacinto y San Jorge, ambas beneficiarias del programa en cuestión y ubicadas en la cuenca baja del río Marañón, en el departamento y provincia de Loreto, en el distrito de Nauta. Los datos cuantitativos registrados, unidos a la observación de campo, permiten analizar de manera crítica el impacto del programa sobre las infraestructuras y la cultura tradicional amazónica. Se sustenta la hipótesis de que los cambios producidos por el programa “techo digno” han sido muy significativos, consolidando la idea de que el programa ha sido inadecuado y ajeno a la realidad cultural y ecológica de la Amazonía.

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

Reverse total shoulder glenoid baseplate stability with superior glenoid bone loss.

Martin, Elise J; Duquin, Thomas R; Ehrensberger, Mark T

2017-10-01

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 picture superiority effect: support for the distinctiveness model.

Mintzer, M Z; Snodgrass, J G

1999-01-01

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.

Full Text Available Apoyando la afirmación de que la investigación sobre la educación superior debería buscar más bien explicaciones y hacerlo, además, con una actitud escéptica, el autor argumenta y documenta que, a principios del siglo XXI, la mayoría de europeos están convencidos de que la educación superior se ve mucho más fuertemente afectada que antes por el hecho de hallarse estrechamente incrustada en ambientes europeos y mundiales. 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. Sin embargo, en la actualidad, no observamos ninguna integración real de las políticas de educación superior por lo que respecta al "proceso de

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.

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.

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.

Full Text Available Las experiencias de las mujeres inmigrantes de color dentro de la educación superior de los Estados Unidos brindan una oportunidad única para entender las complejas influencias de las identidades que se cruzan en el contexto de contextos sociales cambiantes. Para determinar cómo las categorías sociales de género, clase, raza y nacionalidad operan en la experiencia de las mujeres inmigrantes caribeñas de ser estudiantes universitarios, se llevaron a cabo grupos focales con 27 mujeres de habla inglesa nacidas en el Caribe asistiendo a universidades de NYC. Los datos muestran que cuando las mujeres se trasladan a los Estados Unidos provienen de tradiciones culturales de género que determinan sus roles sociales en el Caribe y para la mayoría de las mujeres, estas reglas continúan operando en los Estados Unidos. Sin embargo, los papeles y las tradiciones de género no son homogéneos en todo el Caribe, por lo tanto, hay variación en cómo juegan en las experiencias de las mujeres en los EE.UU. Además, las fronteras anteriormente distintas entre algunas tradiciones del Caribe y las tradiciones estadounidenses están siendo cuestionadas. Estos hallazgos subrayan la compleja influencia de la intersección de las identidades en el papel de las mujeres y llaman la atención sobre cómo afectan la identificación social en el contexto de las actividades universitarias y otros aspectos de sus vidas. A la luz del aumento del contacto intercultural y de la globalización, estos hallazgos proporcionan una mejor comprensión de los factores que afectan el ajuste psicológico de las mujeres inmigrantes caribeñas en los Estados Unidos y tienen implicaciones para mejorar su adaptación a través de contextos sociales cambiantes.

Full Text Available Objetivo: analizar el estado de la partería en Jalisco, México, frente al proceso de profesionalización. Metodología: Estudio de caso, realizado desde junio de 2011 a julio de 2013 en tres momentos: I. Entrevistas a profundidad con 20 parteras, II. Cuatro asambleas regionales con 44 parteras, III. Una asamblea estatal con 136 parteras, personal de salud y otros actores sociales, retomando técnicas educativas populares. Los datos cualitativos fueron analizados bajo el modelo actancial semiótico y los datos sociodemográficos de parteras en Epi Info 7, realizando una meta-inferencia con ambos hallazgos. Resultados: 180 parteras informantes, 89% de zona rural, media de edad 56 años, 73% con estudios de secundaria o menos, 95% son parteras tradicionales, adoptando esta práctica desde la adolescencia, capacitándose en instituciones de salud y entre las mismas parteras; 16,7% estudiaron enfermería buscando posicionamiento institucional, sin dejar de ser parteras. Actualmente otorgan atención materno-infantil y a nosologías tradicionales, aludiendo abandono institucional. Existen posturas de rechazo y aceptación de su incorporación al sector salud en médicos y enfermeras, mientras que otros actores sociales, piden su reconocimiento. Conclusiones: la partería en Jalisco, México, es una práctica tradicional vital, con o sin reconocimiento institucional, transformándose en respuesta a necesidades de atención, teniendo que considerar el perfil sociodemográfico de las parteras, su papel actual, la perspectiva del personal de salud y otros actores sociales, junto con la estrecha relación sociocultural y económica del país, frente a su profesionalización.

Characteristics of neuronal lipofuscin in the superior temporal gyrus in Alzheimer's disease do not differ from non-diseased controls: a comparison with disease-related changes in the superior frontal gyrus.

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.

Acute gluteal compartment syndrome: superior gluteal artery rupture following a low energy injury.

Science.gov (United States)

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.

Sin embargo, presenta diferencias importantes, las cuales ponen de manifiesto las características concretas y distantes de la organización de interés. En el caso de la universidad pública, por ejemplo, es indispensable tener presente las características en torno a sus objetivos (sobre todo la poca importancia en la ganancia y a sus propietarios (especialmente por el fuerte compromiso con los contribuyentes del país.El modelo de evaluación financiera consta de cuatro dimensiones de análisis de las finanzas universitarias: la liquidez o la capacidad de la institución para hacer frente a las obligaciones de corto plazo; la administración de activos; la administración de las deudas; y la eficiencia y la eficacia con que opera la institución. Se pudo determinar que a pesar de la amplia validez del enfoque tradicional en dos de esos aspectos: la liquidez y la administración de deudas, fue necesaria una revisión cuidadosa de los indicadores tradicionales en vista de que las características concretas de la Universidad demostraron la conveniencia del diseño de otros indicadores para lograr una mejor evaluación.Las conclusiones más importantes del estudio son dos: que la evaluación financiera en los términos en que fue planteada no solo es pertinente sino que además es perfectamente factible. Al final se mencionan algunas recomendaciones que persiguen, con los propósitos del estudio, fortalecer el compromiso con el cumplimiento de los objetivos por los que la institución fue creada.

Inflammatory myofibroblastic tumor (IMT) is an uncommon pathological entity of unknown cause, composed of differentiated myofibroblastic cells accompanied by plasma cells, lymphocytes and eosinophils, which involve extrapulmonary and pulmonary tissues. IMT has an unpredictable clinical course, rarely undergoes malignant transformation. Local invasion and involvement of the mediastinum and hiliar structures are unusual manifestations; however; we reports a case of superior vena cava syndrome and IMT

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).

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.

Full Text Available Objectives: To evaluate the surgical treatments and results of the patients with superior oblique muscle palsy (SOMP. Materials and Methods: Clinical charts of the patients with unilateral SOMP who were operated in our clinic between 1999 and 2009 were evaluated retrospectively. Patients’ demographics, preoperative signs, surgical procedure, complications, and final results were recorded. 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. There was statistically significant difference between the two periods (p<0.001. The average score of the superior oblique muscle hypofunction was -2.18 preoperatively, and in only three patients, the score was found -1.0 postoperatively. Difference between the two periods was statistically significant (p<0.001. While the preoperative average vertical deviation was 22 PD in primary position, none of the patients had hyperdeviation postoperatively. Diplopia was resolved in all seven affected patients postoperatively. Contralateral IOM hyperfunction was the most common complication (13.5%. Adherence syndrome was seen in none of the patients. Conclusion: It was found
