The analisis of clinical condition of IgG4-related disease with using imaging examinations
Full text linkIgG4関連疾患は近年確立された全身疾患であるがこれまでの研究ではその全体像は明らかにされてこなかった。このため我々は235例の確定診断症例を集積し、臨床的な情報とともに、全ての画像検査を後方視的に解析し、各症例の罹患臓器を調べた。
その結果患者の男女比は4:1で男性に多く、90%の患者が50-70歳代で診断されていた。また罹患臓器は膵臓病変が最も高頻度で見られ、次いで顎下腺、腎臓、涙腺、大動脈病変の順に頻度が高く、95%の症例がこれらの5病変のうちのひとつを有していたことが明らかになった。また男女で罹患臓器にさが見られた。ステロイド治療は有効であったが24%の症例で再発が見られた。IgG4-related disease is a recently established systemic disease entity and overall picture of it has been unclear. In this research, we collected 235 cases with IgG4-related disease and retrospectively reviewed clinical notes and imaging examinations to reveal the organ manifestation in each patients.
As a result, we revealed that all patients were adults (M/F 4/1) and 90% of the patients were diagnosed in their 50s to 70s. Among all manifestations identified in total, the most common was pancreas, followed by submandibular gland, kidney, lacrimal gland, and aorta. The majority (95%) of patients had at least 1 one the 5 most common manifestations. Male and female patients differed in their organ manifestations. Corticosteroid therapy was effective, but recurrence was seen in 24% of in the study period.研究課題/領域番号:26860986, 研究期間(年度):2014-04-01 - 2016-03-31出典：研究課題「画像検査を用いたIgG4関連疾患の病態解析および病勢評価法の確立」課題番号:26860986

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
画像病理比較を基盤とした限局性自己免疫性膵炎と膵癌の高精度鑑別手法の確立
Full text link自己免疫性膵炎と膵癌は治療法が全く異なり、両者を鑑別することが重要である。膵腫瘤性病変の診断はCT,MRIといった画像診断で行うことが多いが現時点で腫瘤を形成する自己免疫性膵炎(focal AIP)と膵癌を鑑別することは非常に困難である。そのため本研究では膵癌とfocal AIPを画像で鑑別し得る所見を明らかにするために画像所見を比較して検討を行った。
検討の結果、focal AIPでは腫瘤内に点状の濃染がみられ、内部が均一である頻度が有意に高く、また腫瘤辺縁にcapsule-like rimがみられることが特徴であった。こういった画像所見に基づいて今後両者の鑑別が可能となることが期待される。Treatment for autoimmune pancreatitis differ from that for pancreas cancer.Though,the diagnosis of pancreas mass lesions largely depend on imaging examinations such as CT and MRI, imaging discrimination of mass forming autoimmune pancreatitis (focal AIP) and pancreas cancer remains challenging. Thus, in this study, we compared imaging features of focal AIP and pancreas cancer to reveal the imaging findings that can discriminate these two conditions.
We found that multiple dot-like enhancement, homogeneous enhancement and capsule-like rim were noted with high prevalence. Relying on these imaging findings, precise discrimination between focal AIP and pancreas cancer will be expected to be possible.研究課題/領域番号:16K19811, 研究期間(年度):2016-04-01 - 2019-03-31出典：研究課題「画像病理比較を基盤とした限局性自己免疫性膵炎と膵癌の高精度鑑別手法の確立」課題番号16K19811

Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
