La glucemia en la enfermedad de Carrión y en la Bartonellosis del perro
No full textThe author studied the glycemia, prior to food being taken, in normal subjects, in patients suffering from Oroya Fever, and in dogs infected with Bartonella canis. 1. A moderate hyperglycemia, can be proved to exist, with certain frequency, in the hematic stage of Carríon\u27s disease. 2. These changes in the glycemia, are also present, in the experimental dog Bartonelosis, during the stage of intense anemia. 3. An occasionally severe hypoglycemia, probably causing the animals death, often accompanies the terminal stage of serious cases of dog Bartonelosis, and follows the hyperglycemia whenever these two phenomena occur in one and the same case. 4. The hyperglycemia proved to exist both in subjects suffering Irom Carrion\u27s disease, and in dogs seized with Bartonelosis can be explained as being due to an exagerated hepatic glycogenolysis, stimulated by the infectious state and also possibly by the anaemic anoxia. 5. The exhaustion of the glycogene reserve of the liver, caused mainly by an over-consumption of glucose, and by the reduced capacity of the liver to fix this substance, and the probable inhibition of the neoglycogenolysis, would be the factors causing the hypoglycemic condition occurring in serious cases of dog Bartonelosis.Se ha estudiado la glucemia en ayunas en sujetos normales, enfermos carriónicos y perros infestados con Bartonella canis. En estos últimos se ha realizado además dosajes de glucógeno hepático y pruebas de tolerancia a la glucosa. Los resultados obtenidos permiten las siguientes conclusiones: 1.Una hiperglucemia de grado moderado puede ser constatada, con alguna frecuencia, en la fase hemática de la Enfermedad de Carrión. 2. Esta alteración de la glucemia se presenta también en la Bartonellosis experimental del perro, durante la fase de anemia intensa. 3. Una hipoglucemia, a veces de grado severo y responsable probablemente de la muerte del animal, acompaña con frecuencia a la etapa terminal de la Bartonellosis grave del perro, sucediendo a la hiperglucemia cuando ambos trastornos se presentan en el mismo caso. 4. La hiperglucemia constatada tanto en el enfermo carriónico como en el perro bartonellósico, puede ser explicada por una exagerada glucogenolisis hepática, estimulada por el estado infeccioso y quizás también por la anoxia anémica. 5. Un agotamiento de las reservas de glucógeno en el hígado - producido principalmente por un mayor consumo de glucosa y una disminución de la capacidad del mismo para fijar aquella sustancia - y una probable inhibición de la neoglucogenia, serían los factores responsables del estado hipoglucémico que se presenta en la etapa terminal de la Bartonellosis grave del perro
Los ácidos grasos totales y el colesterol total del plasma en la enfermedad de Carrión y en la bartonellosis del perro
No full textSome time ago, decided to study blood lipids Carrión\u27s Disease and the dog Bartonellosis induced by the important findings of Williams and associates in the plasma and erythrocytes of patients with pernicious anemia, and the work of Wintger in dogs with liver injury by carbon tetrachloride.Hace algún tiempo, nos propusimos estudiar los lípidos sanguíneos en la Enfermedad de Carrión y en la Bartonellosis del perro, inducidos por los importantes hallazgos de Williams y asociados en el plasma y eritrocitos de sujetos con anemia perniciosa, y el trabajo de Wintger en perros con lesión hepática por el tetracloruro de carbono
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
