Eixo ECA2/ANG-(1-7)/mas e sua regulação no processo de ovulação
(Universidade Federal de Santa Maria, 2011-02-28)
The Renin-Angiotensin System (RAS) has been associated with various reproductive
functions, including the ovulatory cascade. Unlike angiotensin II (AngII), the role of
angiotensin-(1-7) [Ang-(1-7)] has not been characterized ...

(Universidade Federal de Santa Maria, 2016-07-29)
Reproductive diseases, mainly endometritis, are important hurdles in cattle raising, In the current study we evaluated gross, bacteriological, cytological, and histological findings from selected sites of the genital from ...
Injeção intracitoplasmática de espermatozoide: métodos de ativação oocitária e desestabilização da membrana espermática
(Universidade Federal de Santa Maria, 2017-02-09)
Development of bovine embryos produced by intracytoplasmic sperm injection (ICSI) is low compared to fertilized embryos. Deficient oocyte activation, inappropriate sperm capacitation, and lack of sperm decondensation are ...
Angiotensina II e sua associação com fator-I de crescimento semelhante à insulina, insulina e células foliculares na maturação de oócitos bovinos e conseqüente desenvolvimento embrionário
(Universidade Federal de Santa Maria, 2005-05-06)
The aim of the present study was to evaluate the action of angiotensin II (Ang II), insulin-like growth factor-I (IGF-I) and insulin (Ins) on bovine oocyte nuclear and cytoplasmic maturation with follicular cells. ...
