Epstein-Barr virus induces erosive arthritis in humanized mice.

Epstein-Barr virus (EBV) has been implicated in the pathogenesis of rheumatoid arthritis (RA) on the basis of indirect evidence, such as its presence in affected joint tissues, antigenic cross reactions between EBV and human proteins, and elevated humoral and cellular anti-EBV immune responses in patients. Here we report development of erosive arthritis closely resembling RA in humanized mice inoculated with EBV. Human immune system components were reconstituted in mice of the NOD/Shi-scid/IL-2Rγ(null) (NOG) strain by transplantation with CD34(+) hematopoietic stem cells isolated from cord blood.

Web API for biology with a workflow navigation system.

DNA Data Bank of Japan (DDBJ) provides Web-based systems for biological analysis, called Web APIs for biology (WABI). So far, we have developed over 20 SOAP services and several workflows that consist of a series of method invocations. In this article, we present newly developed services of WABI, that is, REST-based Web services, additional workflows and a workflow navigation system.

[A case of brain metastasis from advanced ovarian clear-cell carcinoma during maintenance chemotherapy with irinotecan+cisplatin].

Clear-cell carcinoma of the ovary is a highly malignant neoplasm. Survival of patients in the advanced stage is poor, and the best treatment is not clear. We report here a case of a 57-year-old woman who had Stage IIIb advanced clearcell carcinoma of the ovary.

Genome Information Broker for Viruses (GIB-V): database for comparative analysis of virus genomes.

Genome Information Broker for Viruses (GIB-V) is a comprehensive virus genome/segment database. We extracted 18 418 complete virus genomes/segments from the International Nucleotide Sequence Database Collaboration (INSDC, http://www.insdc.
