Veterinaarmeditsiini õppekavalPiimanäärme kasvajad on kassidel üks sagedamini esinevaid kasvaja liike maailmas,
moodustades umbes 17% kõikidest emastel kassidel diagnoositud kasvajatest. 85–90%
piimanäärme kasvajatest kassidel on pahaloomulised. Antud asjaolu tõttu on neoplaasiate
varajane tuvastus ja agressiivne ravi olulisel kohal, et hinnata prognoosi elulemusele.
Käesoleva retrospektiivse uurimistöö eesmärgiks oli uurida Eestis erinevate piimanäärme
kasvajate tüüpide esinemist kassidel Eesti Maaülikooli Veterinaarse biomeditsiini ja
toiduhügieeni õppetooli patohistoloogilisse uuringusse saadetud koeproovide põhjal.
Analüüsimiseks kasutati aastatel 2013-2024 laborisse saadetud 120 loomalt kogutud 136
koeproovi patohistoloogilisi raporteid. Saadud andmete põhjal teostati kirjeldav ja statistiline
analüüs Microsoft 365 Excel programmiga. Pahaloomulised kasvajad moodustasid uuritud
proovidest 65.4% (n = 89) ning healoomulised muutused 33.8% (n = 46). Pahaloomulistest
muutustest esines kassidel enim tubulaarset kartsinoomi (n = 23), kompaktset kartsinoomi (n
= 13) ja juhasisest papillaarset kartsinoomi (n = 13). Healoomulistest kasvajatest esines enim
juhasisest papillaarset adenoomi (n = 11) ning piimajuhade adenoomi (n = 11). Piimanäärme
hüper- ja düsplaasiatest diagnoositi enim piimajuhade ektaasiat (n = 5) ja piimajuhade tsüste
(n = 5). Diagnoosimise hetkel oli kasside keskmiseks vanuseks 11.3 aastat ning
mediaanvanuseks 11 aastat. Statistilise analüüsi käigus leiti esinevat tugev seos vanuserühma
ja piimanäärme muutuste pahaloomulisuse vahel. Muude tegurite vahel statistilist olulisust ei
tuvastatud. Üldjuhul ühtisid töö tulemused kirjandusandmetega, kuid proovide ja täiendavate
andmete vähesuse tõttu vajab valdkond Eestis täiendavaid uuringuid.Mammary gland tumors are one of the most common types of tumors in felines, accounting
for approximately 17% of all tumors diagnosed in female cats. 85–90% of mammary tumors
in cats are malignant. Due to this fact, early detection and aggressive treatment is crucial for
assessing the prognosis for survival. The aim of this retrospective study was to investigate
the occurrence of different types of mammary tumors in cats in Estonia, based on tissue
samples sent for histopathological examination to the Chair of Veterinary Biomedicine and
Food Hygiene at the Estonian University of Life Sciences. Histological reports of 136 tissue
samples collected from 120 animals that were sent to the laboratory in the years 2013-2024
were used for analysis. Analysis of the obtained data was performed using Microsoft 365
Excel. Malignant tumors accounted for 65.4% (n = 89) of the samples studied, and benign
changes accounted for 33.8% (n = 46). Among the malignant changes, the most common
types in cats were tubular carcinoma (n = 23), solid carcinoma (n = 13), and intraductal
papillary carcinoma (n = 13). Among the benign tumors, the most common were intraductal
papillary adenoma (n = 11) and ductal adenoma (n = 11). The most frequently diagnosed
hyperplastic and dysplastic changes were duct ectasia (n = 5) and ductal cysts (n = 5). At the
time of diagnosis, the mean age of cats was 11.3 years, with a median age of 11 years.
Statistical analysis revealed a strong correlation between age group and the malignancy of
mammary changes. No statistical significance was found between other factors. In general,
the results of the study were consistent with the literature. Due to the limited number of
samples and additional data, further research is needed in this field in Estonia
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
