Identification of Waldo-A and Waldo-B, two closely related non-LTR retrotransposons in Drosophila.

We have identified two novel, closely related subfamilies of non-long-terminal-repeat (non-LTR) retrotransposons in Drosophila melanogaster, the Waldo-A and Waldo-B subfamilies, that are in the same lineage as site-specific LTR retrotransposons of the R1 clade. Both contain potentially active copies with two large open reading frames, having coding capacities for a nucleoprotein as well as endo...

Where’s Waldo? A new commensal species, Waldo arthuri (Mollusca, Bivalvia, Galeommatidae), from the Northeastern Pacific Ocean

A galeommatid bivalve mollusk, representing a new species, is described from off the coasts of California and Vancouver Island, British Columbia. The new bivalve has a commensal relationship with the heart urchin, Brisaster latifrons. It has been observed crawling between the oral spines of this urchin, frequently near the peristome. The bivalve has been recorded from 80 (Vancouver Island) to 4...

Ureaplasma parvum as a cause of sternal wound infection.

Few reports in the literature have documented the isolation of Ureaplasma species from sternal wounds. A case of sternal wound infection likely due to Ureaplasma parvum is described. When routine bacterial cultures from a sternal wound infection fail to yield a pathogen, diagnostic testing for mycoplasmas and ureaplasmas should be considered.

Phenotypic characterization of retinoblastoma for the presence of putative cancer stem-like cell markers by flow cytometry.

PURPOSE Retinoblastoma (Rb) is an intraocular tumor that grows rapidly and poses a threat to sight and life. Similar to other tumors, there is increasing speculation that the Rb tumor also contains cancer stem-like cells that could influence the prognosis and response to therapy. This study was undertaken in an attempt to identify putative stem-like cells by characterizing different subpopulati...
