2. Cardio-respiratory development in bird embryos: new insights from a venerable animal model
ABSTRACT The avian embryo is a time-honored animal model for understanding vertebrate development. A key area of extensive study using bird embryos centers on developmental phenotypic plasticity of the cardio-respiratory system and how its normal development can be affected by abiotic factors such as temperature and oxygen availability. Through the investiga

3. Investigação dos mecanismos de ação do Amblyomin-X sobre a angiogênese in vivo induzida pelo VEGF / Investigation of mechanisms of action of Amblyomin-X on in vivo on VEGF-induced angiogenesis
Amblyomin-X é um inibidor de serinoprotease do tipo kunitz obtido de uma biblioteca de cDNA das glândulas salivares do carrapato Amblyomma cajannense. Dados preliminares mostraram que a injeção in vivo de Amblyomin-X reduziu a formação de massa tumoral induzida por células de melanoma B16F10 em camundongos. Com base neste dado e na ação de inibidore
