Gene-expression profiles of human tumor xenografts in nude mice treated orally with the EGFR tyrosine kinase inhibitor ZD1839.

TL;DR: The data obtained here should provide useful information on the molecular mechanism underlying clinical responses to EGFR-TKIs, aid the development of novel therapies for lung cancer, and potentially identify predictive molecular markers for sensitivity to ZD1839.

Giant peritoneal loose body in the pelvic cavity: report of a case.

TL;DR: A 63-year-old man who was asymptomatic underwent a routine medical examination, which revealed a tumor in the pelvic space, and a giant peritoneal loose body was found, made up of thick layers of fibrous tissue with a few cellular components, and necrotic fat tissue in the central position.

Rheological properties of middle ear effusions from children with otitis media with effusion.

TL;DR: Freshly harvested middle ear effusions were collected from children with otitis media with effusion and compared with transportability of the MEE on mucus-depleted frog palates to show there is a sharp increase in transport with increase in G′ up to 20 dyne/cm2, and at the higher value of G′there is a slow decrease in Transport with increasing G′.
