Signaling pathways implicated in hematopoietic progenitor cell proliferation and differentiation
(Sage Publications Ltd, London, 2007)
The objective of this study was to investigate the signal transduction pathways associated with the clonal development of myeloid and erythroid progenitor cells. The contribution of particular signaling molecules of protein ...
A human origin type II strain of Toxoplasma gondii causing severe encephalitis in mice
(Elsevier Science Bv, Amsterdam, 2006)
Despite its capacity for sexual reproduction and global distribution, Toxoplasma gondii has a highly clonal structure, with the majority of isolates belonging to three distinct clonal types. Congenital toxoplasmosis has ...
Hematopoietic changes and altered reactivity to IL-17 in Syphacia obvelata-infected mice
(Elsevier Ireland Ltd, Clare, 2006)
Pinworm parasites commonly infect laboratory mice with high prevalence even in well-managed animal colonies. Although often considered as irrelevant, these parasites if undetected may significantly interfere with the ...
Development of a sampling plan for Myzus persicae (Hemiptera : Aphidoidea) and its predator Macrolophus costalis (Hemiptera : Miridae) on tobacco
(Czech Acad Sci, Inst Entomology, Ceske Budejovice, 2005)
A tobacco field in Greece was sampled during the 2001 and 2002 growing seasons to assess the seasonal trends in densities and spatial distributions of the aphid Myzus persicae (Sulzer) and its predatory mirid Macrolophus ...
Effectiveness of spiramycin in murine models of acute and chronic toxoplasmosis
(Elsevier, Amsterdam, 2005)
The antitoxoplasmic activity of spiramycin (SPI) was evaluated in murine models of infection using a type-1 (RH) or type-2 (Me49) strain of Toxoplasma gondii. In mice infected with 10(2) tachyzoites of the RH strain, ...
Dynamic analysis of the power spectral structure in tremor in Parkinson's disease and in essential tremor
(Wiley-Blackwell, Malden, 2008)
Hydroxyurea increases eNOS protein levels through inhibition of proteasome activity
(Academic Press Inc Elsevier Science, San Diego, 2007)
Recent reports have identified the proteasome as the primary degradation pathway for inducible, neuronal and endothelial nitric oxide synthase (NOS). We have demonstrated that hydroxyurea increased nitric oxide (NO) ...
Effects of gamma-radiation on cell growth, cycle arrest, death, and superoxide dismutase expression by DU145 human prostate cancer cells
(Assoc Bras Divulg Cientifica, Ribeirao Preto, 2006)
Gamma-irradiation (gamma-IR) is extensively used in the treatment of hormone-resistant prostate carcinoma. The objective of the present study was to investigate the effects of Co-60 gamma-IR on the growth, cell cycle arrest ...
