Development of novel treatments of myeloma based on MRD using next-generation sequencing and protein-array assay
Get PDF多発性骨髄腫症例での微小残存病変（MRD)検出する方法である次世代シークエンサー(NGS)法、マルチパラメーターフローサイトメトリー(MFC)法を確立し、骨髄や自家移植片中のMRD検査を実施した。その結果、MRDが陰性の場合に極めて良好な無増悪生存や全生存となった。その結果に基づいて、NGSとMFCによるMRD検出の臨床的意義を検証する多施設前向き臨床研究(UMIN-CTR ID: UMIN000022238)を開始した。一方、NGSやMFCでMRDが陰性となった極めて深い奏効を達成した多発性骨髄腫症例の血清中で検出される抗X抗体のターゲット抗原Xは、癌精巣抗原の1種であることを明らかにした。We demonstrated the clinical value of minimal residual disease (MRD) detection in multiple myeloma (MM) patients using next-generation sequencing (NGS) and multiparameter flow cytometry (MFC). When MRD negativity in bone marrow and/or autografts of MM patients was achieved, the progression-free survival and overall survival were dramatically improved. Based on the results, we have started the clinical study "Prognostic value of minimal residual disease detection using multiparameter flow cytometry (EuroFlow method) in patients with multiple myeloma who underwent autologous stem cell transplantation: comparison with sequencing-based method (UMIN-CTR ID: UMIN000022238)". On the other hand, we clarified that anti-X antibody which is detected in the sera of MRD negative MM patients binds to a cancer-testis antigen X.研究課題/領域番号:15K08644, 研究期間(年度):2015-04-01 - 2018-03-31出典：研究課題「次世代シークエンサーと蛋白質アレイを用いた骨髄腫病態解析と新規治療法の開発」課題番号15K08644

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
Generation of bone marrow failure model mice by autoantibodies inducing cytokine production
Get PDFモエシンKOマウスは以下の表現型異常が認められた。末梢血白血球減少、貧血、体重減少と脾腫大、骨髄造血幹細胞の減少、骨髄・脾臓のB細胞・形質細胞の減少とT細胞の増加、脾臓の濾胞構造の不明瞭化である。一方、モエシンKOマウスにモエシン蛋白質を免疫したところ、抗モエシン抗体が産生された。前処置後の野生型マウスに抗モエシン抗体を産生する脾臓・骨髄細胞を骨髄内移植したところ、野生型マウスに抗モエシン抗体産生、TNFαとIFNγ濃度の上昇、白血球減少がみとめられたが、血小板減少と貧血は認められなかった。Moesin KO mice grew normally. However, the body weight of moesin KO mice was lower than that of WT mice. Complete blood counts of moesin KO mice revealed leukocytopenia and macrocytic anemia ; platelet counts were comparable. Moesin KO mouse spleens were heavier than those of WT mice and follicle formation in spleens of moesin KO mice were obscure with increased CD3^+lymphocytes and reduced CD19^+lymphocytes as compared with WT mice. BM of moesin KO mice was normocellular and characterized by increased CD3^+lymphocytes and reduced CD19^+lymphocytes as seen in spleens of moesin KO mice. The number of lineage negative, Sca-1^+, and c-Kit^+(LSK) mouse HSCs in moesin KO BM tended to be lower than that of WT mice. Moesin KO spleen/BM cells capable of producing anti-moesin antibodies were infused into BM of WT B6 male mice. Transplanted mice showed leukocytopenia and increase of TNFαand IFNγin plasma compared to WT B6 male mice transplanted with WT spleen/BM cells, but anemia and thrombocytopenia were not observed.研究課題/領域番号:21591237, 研究期間(年度):2009-2011出典：研究課題「サイトカイン産生を誘導する自己抗体を用いた骨髄不全モデルマウスの作成」課題番号21591237

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
Production of monoclonal antibodies using B cells derived from patients and their clinical application
Get PDF本研究では、抗HLA抗体を産生している患者B細胞と細胞アレイを用いてこれまで作製ができなかった新規抗HLAモノクローナル抗体の作製を行った。これまでに作製に成功した抗HLA-B61とBw4モノクローナル抗体に加えて, A33, B13, B35, B48, B53, B54等のHLA抗原と反応する新規モノクローナル抗体産生遺伝子組換え細胞を作製した。これらのモノクローナル抗体を用いたフローサイトメトリー検査で微小残存病変、同種造血幹細胞移植後のキメリズム解析、免疫抑制療法が奏効しやすい再生不良性貧血の診断が可能になった。In this study, using peripheral B cells derived from donors and cell-arrays we have created novel monoclonal antibodies that could not be made using conventional methods. In addition to monoclonal antibodies against HLA-B61 and Bw4, we could create recombinant cells that secrete antibodies against HLA-A33, B13, B48, B53 and B54 and so on. Using these novel monoclonal antibodies, we can monitor minimal residual disease, chimerism after allogeneic stem cell transplantation and identify patients with aplastic anemia who respond to immunosuppressive treatments by flow cytometry.研究課題/領域番号:18K07293, 研究期間(年度):2018-04-01 – 2021-03-31出典：「 患者B細胞を用いたモノクローナル抗体作製とその臨床応用」研究成果報告書 課題番号18K07293

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
