The main purpose of this study was to investigate the role of Knowledge Management (KM) in Organizational Entrepreneurship (OE) among agriculture extension workers at Kermanshah Township, Iran. The statistical population in this study consisted of all agriculture extension workers of Jihad-e-Agriculture management and centers of agricultural services at Kermanshah Township (N=143), of whom 129 ...

Ewing's sarcoma is a pediatric tumor that mainly occurs in soft tissues and bones. Malignant characteristics of Ewing's sarcoma are correlated with expression of EWS oncogene. We achieved knockdown of EWS expression using a plasmid vector encoding EWS short hairpin RNA (shRNA) to increase anti-tumor mechanisms of taxifolin (TFL), a new flavonoid, in human Ewing's sarcoma cells in culture and an...

More than 85% of Ewing's family tumors carry a specific chromosomal translocation that fuses the NH(2) terminus of the EWS gene to the COOH terminus of the FLI1 transcription factor. It has been shown previously that both the transactivation domain encoded by EWS and the DNA binding domain of FLI1 were necessary for transforming cells to anchorage independence. We now report that a COOH-termina...

EWS encodes a ubiquitously expressed RNA binding protein with largely unknown function. In Ewing sarcoma family tumors (EFT), one allele is rearranged with an ETS gene. This is the first description of an EFT with a complete EWS deficiency in the presence of two copies of a rearranged chromosome 22 carrying an interstitial EWS-FLI1 translocation. Absence of EWS protein suggested that it is disp...

In Ewing's sarcomas, chromosomal translocations cause the N-terminal domain of the EWS (Ewing's sarcoma protein) to fuse with the DNA-binding domains of the Ets (E26 transformation-specific) family of transcription factors. Here we show that EWS and EWS-Fli1 (Friend leukaemia virus integration 1), the fusion most frequently found in Ewing's sarcomas, become phosphorylated at Thr(79) in response...

INTRODUCTION: In over 85% cases of Ewing’s sarcoma and peripheral primitive neuroectodermal tumors (PNET), a highly specific and recurrent t(11;22) balanced chromosomal translocation results in the fusion of the 5’ half of a gene known as EWS on chromosome 22 to the 3’ portion of the chromosome 11-derived gene FLI-1. The resultant EWS/FLI-1 fusion protein contains EWS-derived sequence as its N-...

The Ewing sarcoma protein (EWS) is a well-known player in cancer biology for the specific translocations occurring in sarcomas. The EWS-FLI1 gene fusion is the prototypical translocation that encodes the aberrant, chimeric transcription factor, which is a landmark of Ewing tumors. In all described Ewing sarcoma oncogenes, the EWS RNA binding domains are completely missing; thus RNA binding prop...

More than 85% of Ewing’s family tumors carry a specific chromosomal translocation that fuses the NH2 terminus of the EWS gene to the COOH terminus of the FLI1 transcription factor. It has been shown previously that both the transactivation domain encoded by EWS and the DNA binding domain of FLI1 were necessary for transforming cells to anchorage independence. We now report that a COOH-terminal ...

EWS, a pro-oncoprotein which is encoded by the Ewing sarcoma (EWS) gene, contains arginine-glycine-glycine repeats (RGG box) in its COOH-terminus. We previously found that the RGG box of EWS is a target for dimethylation catalyzed by protein arginine methyltransferases (PRMTs). Although it has been observed that arginine residues in EWS are dimethylated in vivo, the endogenous enzyme(s) respons...

Crowdsourcing has the potential to become a crucial information source in disaster management. In order to become effective as an integrated part of disaster management systems it is important to set the general architectural foundations for such integrations beyond prototypical experiments. This paper discusses general architectural principles of the application of crowdsourcing in Early Warni...
