1. CARACTERIZAÇÃO MOLECULAR DOS COMPONENTES DO SISTEMA ANGIOTENSINA-(1-7) DURANTE A DIVERGÊNCIA FOLICULAR E EXPRESSÃO DE GENES DE REPARO DA FITA DUPLA DE DNA EM EMBRIÕES BOVINOS / MOLECULAR CHARACTERIZATION OF THE ANGIOTENSIN-(1-7) SYSTEM COMPONENTS DURING FOLLICULAR DEVIATION AND EXPRESSION OF DNA DOUBLE-STRANDED REPAIR GENES IN BOVINE EMBRYOS
The first study characterized the expression of MAS receptor and key enzymes for Ang-(1-7) production, such as, ACE2, NEP and PEP during follicular development. Furthermore, the regulation of local Ang1-7 system was evaluated after the intrafollicular injection of fulvestrant (an estradiolreceptor inhibitor) in the dominant follicle. Cows were ovariectomized

2. EIXO ECA2/ANG-(1-7)/MAS E SUA REGULAÇÃO NO PROCESSO DE OVULAÇÃO / ECA2/ANG-(1-7)/MAS AXIS AND ITS REGULATION DURING THE PROCESS OF OVULATION
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 in the ovary of mono-ovulatory species. The objective of this study was to determine the Ang-(1-7) concentration in follicular fluid an

3. EFFECT OF ANGIOTENSIN II ON BOVINE OOCYTE NUCLEAR MATURATION MEDIATED BY PGE2 AND PGF2α / O EFEITO DA ANGIOTENSINA II NA MATURAÇÃO NUCLEAR DE OÓCITOS BOVINOS É MEDIADO PELAS PROSTAGLANDINAS E2 E F2α
Em mamíferos, é bem estabelecido que o reinício da meiose ocorre após o pico préovulatório de LH e resulta no rompimento da vesícula germinativa (RVG), iniciando a maturação do oócito. Entretanto, a via pela qual essa gonadotrofina atua não está completamente elucidada. Nosso grupo demonstrou que a angiotensina II (AngII) apresenta uma importante

4. THE ROLE OF ANGIOTENSIN II ON EARLY MECHANISM OF BOVINE OVULATION VIA AT2 RECEPTOR SUBTYPE / ANGIOTENSINA II NO MECANISMO INICIAL DE OVULAÇÃO, ATRAVÉS DOS RECEPTORES AT2, EM BOVINOS
The aim of this work was to investigate the role of angiotensin II (Ang II) in the mechanism of ovulation in the bovine, using an in vivo model, through the injection of the Ang II receptor antagonists in mature follicles. The animals were pre-synchronized and when the follicles reached a minimum diameter of 12mm, they received the treatments and were challe

5. Induction by cholera toxin of synchronous divisions in vivo in the epidermis resulting in hyperplasia.
Intracutaneous injection of cholera toxin, exotoxin of Vibrio cholerae, into the dorsal skin of mice, rats, and hamsters at doses of greater than 0.1 ng evoked an acute reaction at the site of injection, which was characterized histologically by an edematous reaction in the dermis and mitotic stimulation in the epidermis. Mitotic and labeling induces of basa
