Interval between first dose and booster affected antibody production in cattle vaccinated against rabies
Provedor de dados: 80
Autores: Albas,A.; Fontolan,O. L.; Pardo,P. E.; Bremer Neto,H.; Sartori,A.
In this study, we compared the levels of neutralizing antibodies induced by inactivated rabies vaccine in cattle by using three alternative immunization procedures. Forty-five bovines (breed nelore) were then organized in three groups (A, B and C, with 15 animals/group). Group A received only one vaccine dose at day zero and Group B received the first dose at day zero and then another dose at day 30 (early booster). Group C was also immunized with two doses; however, the booster was postponed until day 180 after the first dose (delayed booster). Blood samples were withdrawn at days zero (before the first dose) and 30, 210, 390, and 540 after the beginning of immunization and the antibody titers were evaluated by mouse neutralization test. The protocol used...

Eficácia de imazapic e sulfentrazone sobre Cyperus rotundus em diferentes condições de chuva e palha de cana-de-açúcar
Provedor de dados: 87

Nas áreas de colheita de cana-de-açúcar sem queima prévia (cana-crua), a presença da palha afeta a germinação de plantas daninhas e a dinâmica dos herbicidas. O presente trabalho foi conduzido com o objetivo de avaliar os efeitos do sulfentrazone e imazapic, associado à palha de cana-de-açúcar, com chuva após a aplicação dos herbicidas, no controle de Cyperus rotundus. O delineamento experimental adotado foi o de blocos casualizados no esquema fatorial 3 x 3 x 2 x 2, com quatro repetições, totalizando 144 parcelas. Os tratamentos foram conseqüência da combinação fatorial entre três níveis do fator palha de cana-de-açúcar (20, 10 t ha-1 e ausência de cobertura morta sobre o solo); três níveis do fator herbicida (sulfentrazone a 800 g ha-1, imazapic a 147 g...

Chromium oxide (51Cr2O3 ) used as biological marker was not absorbed by fish
Provedor de dados: 45
Autores: Sakita,G.Z.; Meira,D.C.; Bremer Neto,H.; Cyrino,J.E.P.; Abdalla,A.L.
The aim of this study was to evaluate the rate absorption of radio-labeled chromium oxide (51Cr2O3), used as biological marker in nutrition studies with Nile tilapia Oreochromis niloticus. An experimental diet with approximately 58 µCi of specific activity of the element was encapsulated and fed daily to 35 adult Nile tilapia; a group of 35 fish was used as control feeding on a basal diet. At the beginning of the experiment five fish from each group were randomly selected and blood samples were drawn from control (BC) and experimental fish (BE). Fish were then euthanized by anesthetic overdoses and samples of the liver tissue (LT), renal tissue (RT), stomach without content (S), intestine without content (I), gills tissue (GT), muscle tissue (fillet; MT),...
