TRATAMENTO CIRÚRGICO BEM-SUCEDIDO DO SHUNT MESENTÉRICO ESPLENO-RENO-CAVA CONGÊNITO EM UM CÃO
No full textO sistema porta é uma via de captação do sangue que é drenado pelo retorno venoso do baço, estômago e alças intestinais. As veias desses órgãos confluem-se, formando a veia porta, que conduz o sangue ao fígado, para o primeiro ciclo do metabolismo de toxinas e nutrientes. Alguns vasos anômalos podem estar presentes ao nascimento e alterar a anatomia vascular, fazendo com que parte do sangue proveniente das alças intestinais e do baço seja escoado diretamente na grande circulação, sem que ocorra a passagem pelo fígado. Esse fenômeno causa o acúmulo de substâncias tóxicas na circulação, gerando lesões sistêmicas.O presente relato refere-se a um cão macho, da raça Bulldog Inglês, de 9 meses de idade, que apresentava inapetência, prostração, diarréia intermitente e ascite. Os resultados dos exames laboratoriais revelaram hipoproteinemia, elevação nos níveis séricos das enzimas hepáticas, anemia e bilirrubinúria. Mediante a suspeita ultrassonográfica de anomalias vasculares intra-abdominais, o paciente foi encaminhado à tomografia, que confirmou a existência de numerosos vasos anômalos, que comunicavam o cólon descendente e o hilo esplênico à veia renal esquerda e à veia cava caudal, o que caracteriza um shunt mesentérico espleno-reno-cava. Realizou-se a laparotomia exploratória e identificação dos desvios vasculares. Tiras de papel celofane foram implantadas ao redor dos vasos, com o objetivo de obter a oclusão vascular progressiva total. A evolução pós-operatória foi extremamente satisfatória, havendo remissão dos sinais clínicos e normalização dos exames laboratoriais. Em revisão da literatura, não foi encontrado qualquer relato de correção cirúrgica bem-sucedida desse tipo de afecção
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Sutura fabelo-tibial con tunelización de plato para tratar ruptura de ligamento cruzado craneal en perro
No full textAnamnesis. Canine, whole, male, mixed race, with 10 years of age and 7.3 kilograms of weight. Consult motive. Bilateral lower limb claudication since four months ago with progressive worsening of the signs, that are accentuated by walking, with no response to previous treatments. Clinical and radiological findings. The patient refuses to forced walking and has abnormal movement, xyphosis with weight shifting towards the lower limbs, posterior train wobble with flight arch modification, craneal displacement of the right tibia with use, atrophy of the femoral cuadriceps and deformity of the tibial bone columns, pain on both knees to the forced movements and positive bilateral box sign.Radiologically, it presents cranial displacement of the tibia, capsular enthesophytes and articular osteophytes, subchondral sclerosis and cranial displacement of the infra-patellar fat. Definitive diagnosis. Craneal cruciate ligament rupture with bilateral medial meniscus lesion. Surgical approach. It was decided to use a modified surgical technique, titled fabelo-tibial suture with tunneling of the plate, which achieved stability of both affected knees. Conclusions. The favorable evolution, weight support during ambulation with clinical recovery after 90 days, allow us to say that the technique is efficient and effective as an alternative to treat CrCLR in dogs.Anamnesis.
