The Drosophila memory gene amnesiac (amn) has been proposed to encode a neuropeptide protein, which includes regions homologous to vertebrate pituitary adenylyl cyclase-activating peptide (PACAP; Feany and Quinn, 1995). Definitive experiments to link this gene to memory formation, however, have not yet been accomplished (Kandel and Abel, 1995). The experiments described here demonstrate that th...

The lambda interferons (IL-28a, 28b, and IL-29) inhibit the replication of many viruses, but their role in the inhibition of HIV-1 infection remains unclear. During this study, we monitored IL-29 production in HIV-1 infected individuals and analyzed the in vitro and in vivo inhibition of HIV-1 production. Prior treatment with IL-28a or IL-29 induced an antiviral state in cultured primary T-cell...

objective(s): the ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. the aim of this study was to evaluate the uptake of 18ffluorothymidine (flt) pet in renal cell carcinoma (rcc), and to compare this to 18f-fluorodeoxyglucose (fdg), and to an immunohistochemical measure of cellular proliferatio...
