OpenStreetMap (OSM), based on collaborative mapping, has become a subject of great interest to the academic community, resulting in a considerable body of literature produced by many researchers. In this paper, we use Latent Semantic Analysis (LSA) to help identify the emerging research trends in OSM. An extensive corpus of 485 academic abstracts of papers published during the period 2007–2016 ...
As open source volunteered geographic information continues to gain popularity, the user community and data contributions are expected to grow, e.g., CloudMade, Apple, and Ushahidi now provide OpenStreetMap © (OSM) as a base layer for some of their mapping applications. This, coupled with the lack of cartographic standards and the expectation to one day be able to use this vector data for more ...
Fetal liver, the major site of hematopoiesis during embryonic development, acquires additional various metabolic functions near birth. Although liver development has been characterized biologically as consisting of several distinct steps, the molecular events accompanying this process are just beginning to be characterized. In this study, we have established a novel culture system of fetal muri...
INTRODUCTION Interleukin (IL)-6-type cytokines exert their effects through activation of the Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling cascade. The JAK/STAT pathways play an important role in rheumatoid arthritis, since JAK inhibitors have exhibited dramatic effects on rheumatoid arthritis (RA) in clinical trials. In this study, we investigated the mol...
The binding and functional properties of a set of six mAb directed against the human gp190 [leukemia inhibitory factor (LIF) receptor] signal transducing molecule were determined. Each of the antibodies reacted with a distinct epitope on gp190 expressed either by gp190-transfected Chinese hamster ovary cells or by the LIF receptor-positive choriocarcinoma JAR cell line. Two of the antibodies (1...
Oncostatin M (OSM), a glycoprotein of Mr approximately 28,000 produced by activated monocyte and T-lymphocyte cell lines, was previously identified by its ability to inhibit the growth of cells from melanoma and other solid tumors. We have detected significant similarities in the primary amino acid sequences and predicted secondary structures of OSM, leukemia-inhibitory factor (LIF), granulocyt...
یکی از مهمترین کاربردهای GIS درزمینه مدیریت بحران مدلسازی شبکه معابر شهری است. در این پژوهش با دریافت دادههای OSM ابتدا خطا و صحت دادههای موردنظر بررسی سپس پایگاه داده هوشمند برای شبکه معابر شهری تبریز جهت تجزیهوتحلیلهای شبکه در محیط GIS طراحی شد، و در ادامه موقعیت ایستگاه مترو آبرسان نسبت به مسیرهای بهینه دسترسی مراکز امدادی با استفاده از مدل تحلیل شبکه در GIS مدلسازی شد. هدف پژوهش علاو...
Oncostatin M (OSM), an interleukin 6-type cytokine, induces sustained up-regulation of CCAAT/enhancer-binding protein (C/EBP) delta mRNA and protein in nonneoplastic HC11 mouse mammary epithelial cells. This up-regulation is dependent on signaling by phospho-Stat3 (signal transducers and activators of transcription). The same signaling pathway is activated in two human breast cancer cell lines,...
The growth in the number of users and the volume of information in OpenStreetMap (OSM) indicate the success of this VGI-based project in attracting diverse sets of people from all over the world. A huge amount of information is generated daily by non-professional users and OSM faces the challenge of ensuring data quality. Spatial data quality comprises several basic elements; among them, logica...
Activation of the signaling transduction pathways mediated by oncostatin M (OSM) requires the binding of the cytokine to either type I OSM receptor (leukemia inhibitory factor receptor/gp130) or to type II OSM receptor (OSMR/gp130). In the present work we have developed an enzyme-linked immunosorbent assay detecting a soluble form of OSMR (sOSMR) secreted by glioblastoma, hepatoma, and melanoma...
