Molecular and cytogenetic characterization of expanded B-cell clones from multi...
Henriques, A; Rodriguez-Caballero, A; Criado, I; Langerak, AW; Nieto, WG; Lecrevisse, Q; Gonzáles, M; Cortesão, E; Paiva, A; Almeida, J; Orfão, AChronic antigen-stimulation has been recurrently involved in the earlier stages of monoclonal B-cell lymphocytosis, chronic lymphocytic leukemia and other B-cell chronic lymphoproliferative disorders. Among these individuals, expansion of ≥2 B-cell clones has been frequently reported; potentially, such coexisting clones have a greater probability of interaction with common immunological determinants. Here, we c...
Effects of azadirachtin in Rhodnius prolixus: data and hypotheses
Garcia,E. S.; Gonzales,M. S.; Azambuja,P.The effects of azadirachtin A, a tetranortriterpenoid from the neem tree Azadirachta indica J., on both development and interaction between Trypanosoma cruzi, the causative agent of Chagas' disease, and its vector Rhodnius prolixus were studied. Given through a blood meal, a dose-rsponse relationship of azadirachtin was established using antifeedant effect and ecdysis inhibition as effective parameters. A singl...
