Calcifying Fibrous Pseudotumor of the Posterior Mediastinum With Encapsulation of the Thoracic Duct.

We report the first case of calcifying fibrous pseudotumor (CFPT) to arise in the posterior mediastinum with encapsulation of the thoracic duct. This exceedingly rare lesion was incidentally discovered in an asymptomatic young woman and treated with surgical resection, requiring ligation and excision of the thoracic duct. There has been no evidence of tumor recurrence or postoperative complication.

aeGEPUCI: a database of gene expression in the dengue vector mosquito, Aedes aegypti.

Background: Aedes aegypti is the principal vector of dengue and yellow fever viruses. The availability of the sequenced and annotated genome enables genome-wide analyses of gene expression in this mosquito. The large amount of data resulting from these analyses requires efficient cataloguing before it becomes useful as the basis for new insights into gene expression patterns and studies of the underlying molecular mechanisms for generating these patterns.

angaGEDUCI: Anopheles gambiae gene expression database with integrated comparative algorithms for identifying conserved DNA motifs in promoter sequences.

Background: The completed sequence of the Anopheles gambiae genome has enabled genome-wide analyses of gene expression and regulation in this principal vector of human malaria. These investigations have created a demand for efficient methods of cataloguing and analyzing the large quantities of data that have been produced. The organization of genome-wide data into one unified database makes possible the efficient identification of spatial and temporal patterns of gene expression, and by pairing these findings with comparative algorithms, may offer a tool to gain insight into the molecular mechanisms that regulate these expression patterns.
