First endangered huemul deer (Hippocamelus bisulcus) confirmed with iodine deficiency: A case report
Background: Huemul (Hippocamelus bisulcus) an endangered endemic cervid of Chile and Argentina, is currently confined year-round mainly to their historic summer range in the Andean mountains, with complete loss of migratory behavior due to anthropogenic activity. Trace mineral deficiencies, such as selenium and iodine, in the soils of their current year-round home range have been hypothesized to explain the lack of the species’ recovery. This hypothesis has been supported by osteopathy of numerous skeletal remains, particularly in the cranium and dentary bones, with prevalent loss of teeth even at a young age. Such lesions negatively affect foraging, the ability to avoid predators, and thus contribute to the low average adult age and lack of population recovery. Low iodine levels in the Andean mountain region is causing a high frequency of associated disease in both humans and livestock. Prenatal iodine deficiency in livestock, for instance, is causing frequent perinatal mortality and neonates with congenital anomalies. Here we document results of the first-ever analysis of the iodine status in a huemul deer. Methods: Serum was used to analyze Thyrotropin via chemiluminescence immulite, Thyroxine via chemiluminescence, and Triiodothyronine via electrochemiluminescence. Results: Blood tests revealed <0,01 ng/mL for Thyrotropin, 6,9 ug/dL for Thyroxine, and 83,5 ng/dL for Triiodothyronine. Conclusions: Compared to several studies on other Odocoiline deer, the huemul was clearly deficient in iodine.Fil: Fluck, Werner Thomas.

Insuficiencia renal crónica en un puma del bioparque Temaiken : reporte de caso
17 páginas : gráficas, fotografíasEn el siguiente caso se reporta un ejemplar de puma geronte de 17 años de edad, que fue llevado al hospital veterinario del Bioparque Temaikén, debido a que llevaba cuatro días aproximadamente presentando comportamiento anormal, se encontraba decaído y sin consumir dieta; para el ingreso y salida al exhibidor presentaba dificultades para movilizarse. En el momento que se interviene el animal se realizan placas radiográficas, ecografía abdominal, extracción de sangre y orina, se instaura tratamiento y queda hospitalizado para observación. Al obtener los resultados de los exámenes se diagnostica insuficiencia renal crónica; por ello se instaura un nuevo tratamiento para un paciente renal, sin embargo, al pasar de los días el animal no presentó mejoras y se decide realizar eutanasia al paciente.In the following case 17-year-old cougar was reported, the feline was taken to the veterinary hospital of temaikén biopark, due to abnormal behavior for the past four days, the patient was in a state of decay and without consuming any nourishment, while some difficulties were presented whenever the animal was entering the exhibitor. At the moment we intervened the animal so we could gather more data about it's condition (some radiographic plates, abdominal ultrasound, blood and urine extraction were performed), after gathering all the information needed, the patient was hospitalized so we could start treatment and observation. Once the results were available, the feline was diagnosed as chronic renal failure, a new course of action was taken for a for renal patient, however, as the days went by the animal did not present any improvements so it was decided to euthanize the patientIncluye bibliografíaPregradoMédico(a) Veterinari
Bronconeumonía en un ejemplar de Chita reporte de caso
24 páginas : fotografías, gráficasEl caso clínico se desarrolló en el “Bioparque Temaikèn” (Escobar – Argentina) sobre un ejemplar de Chita (Acinonyx jubatus), hembra geronte, que llevaba más de 15 años bajo cuidado humano y presentando los siguientes signos clínicos: hiporexia, vocalización, ojos entrecerrados, cola entre las patas y postración esternal. Dificultándose la salida del recinto de exhibición (a menor velocidad de lo usual), manteniéndose bajo observación clínica constante por un período de 7 días.
Los hallazgos clínicos arrojaron los siguientes resultados mediante radiografías torácicas y ecografías abdominales: patrón pulmonar bronco-intersticial y hallazgo de nodulaciones múltiples en bazo, produciéndose la muerte del ejemplar el 25 de agosto de 2018. La necropsia arrojó como resultado los diagnósticos diferenciales de Bronconeumonía y Neumonía, decidiéndose realizar exámenes complementarios de histopatología para intentar hallar el agente causal de la condición.
Por otro lado, se concluye que la edad es un factor de riesgo y predisponente, en el chita, teniendo en cuenta que el factor climático (invierno) puede llegar a alterar el sistema respiratorio causando una colonización de “Pasteurella spp”, con el agravante de haber sido anestesiada para su abordaje a revisión clínica.The present case was carried out in the "Temaikèn Biopark" (Escobar - Argentina), being currently the only case presented of an old female Chita (Acinonyx jubatus) that had been under human care for more than 15 years presenting the following clinical signs: hyporexia, vocalization , eyes narrowed, tail between the legs and sternal prostration. This makes it difficult to go to the exhibition venue (with a lower speed than usual), keeping constant clinical observation for a period of 7 days.
The clinical findings yielded the following results by means of a thoracic ultrasound: Nodulations in the spleen and a pulmonary pattern, leading to his death on August 25, 2018. The necropsy resulted in a differential diagnosis of bronchopneumonia and pneumonia, deciding to perform exams complementary histopathology, to find the causal agent of his death. It is concluded that age is a risk factor in cheetah, however, the climatic factor (winter) can alter the respiratory system causing a colonization of "Pasteurella" with the aggravating circumstance of having been anesthetized.Incluye bibliografíaPregradoMédico(a) Veterinari
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
