1. Strategies to increment in vivo and in vitro embryo production and transfer in cattle
Abstract Knowledge of follicular wave dynamics obtained through the use of real-time ultrasonography and the development of the means by which follicular wave dynamics can be controlled have provided practical approaches for the in vivo and in vitro production and transfer of embryos in cattle. The elective control of follicular wave emergence and ovulation

2. Impact of historic histopathologic sample review on the risk of recurrence in patients with differentiated thyroid cancer
ABSTRACT Objective To compare the historic risk of recurrence (RR) and response to therapy to risk stratification estimated with historical pathology reports (HPRs) and contemporary re-review of the pathological slides in patients with differentiated thyroid cancer (DTC). Subjects and methods Out of 210 DTC patients with low and intermediate RR who underwe

3. Indução de codominância e dupla ovulação e novas abordagens em luteólise de bovinos / Induced codominance and double ovulation and new approaches on luteolysis in cattle
The day-4 ablation model for increasing the incidence of double ovulations in heifers was used for the chapters 2 and 3. In this regard, follicles ≥ 5 mm were ablated at 4 d post-ovulation to induce a prominent FSH surge and a new follicular wave, and two injections of prostaglandin F2α (12 h apart) were given two days later (6 d) to favor ovulati

4. Resposta superovulatória após ablação folicular usando um dispositivo simplificado em bovinos (Bos taurus taurus) / Superovulatory response following follicle ablation using a simplified transvaginal device in beef cattle (Bos taurus taurus)
A influência do momento da ablação do folículo dominante antes do início do tratamento superovulatório, e seu efeito sobre a dinâmica folicular ovariana e a taxa de produção de embriões, ainda permanece indeterminada em bovinos. O presente estudo foi desenvolvido com objetivo de avaliar a resposta superovulatória de fêmeas da raça Limousin, dete

5. The removal of the dominant follicle as antiluteolytic strategy in cattle / A remoção do folículo dominante como estratégia anti-luteolítica em bovinos
Estradiol secreted from the dominant follicle (DOM) plays a key role in triggering luteolysis in the cow. In addition, maternal recognition of pregnancy (MRP) requires an optimum uterine environment, which directly depends on luteal function and adequate levels of circulating progesterone. The aim of this study was to test different strategies to optimize lu

6. Role of estradiol on bovine luteolysis: estradiol stimulates PGF2&alpha througthout P4 receptor activation in the endometrium? / As funções do estradiol no processo da luteólise em bovinos: o estradiol estimula PGF2α através da ativação de receptores de P4 no endométrio?
Estradiol (E2) is essential for triggering luteolysis in ruminants. The low E2 concentrations after follicular ablation prolongs luteolysis instead of E2 injections in late luteal phase stimulate prostaglandin F2α (PGF2α) and luteolysis. The E2 could act in endometrium avoiding progesterone (P4 ) to stimulate PGF 2α secretion. A P4 antagoni

7. Efficient Lymphoreticular Prion Propagation Requires PrPc in Stromal and Hematopoietic Cells
In most prion diseases, infectivity accumulates in lymphoreticular organs early after infection. Defects in hematopoietic compartments, such as impaired B-cell maturation, or in stromal compartments, such as abrogation of follicular dendritic cells, can delay or prevent lymphoreticular prion colonization. However, the nature of the compartment in which prion
