1. Study of follicle deviation and ovulatory capacity in buffaloes (Bubalus bubalis) and zebu cattle (Bos indicus) / Estudo da divergência folicular e da capacidade ovulatória em bubalinos (Bubalus bubalis) e zebuínos (Bos indicus)
Present study is presented in Chapter 1 (Follicle deviation; FD) and 2 (Ovulatory capacity). Each chapter includes two experiments [1 - in buffaloes (Bubalus bubalis); 2 - in zebu cattle (Bos indicus)]. In Chapter 1, aims were to determine moment and diameter deviation and to evaluate FSH and LH plasmatic profiles encompassing follicle selection. In Experime

2. Restoration of ovulatory cycles by young ovarian grafts in aging mice: potentiation by long-term ovariectomy decreases with age.
The relative contributions of ovarian and hypothalamic-pituitary factors to the anovulatory status of aging mice were evaluated by measuring the capacity of mice to resume ovulatory cyclicity after receiving young ovaries under the renal capsule. Young grafts partially restored cyclicity if old hosts were acutely ovariectomized but almost fully restored cycl

3. Immature rats show ovulatory defects similar to those in adult rats lacking prostaglandin and progesterone actions
Gonadotropin-primed immature rats (GPIR) constitute a widely used model for the study of ovulation. Although the equivalence between the ovulatory process in immature and adult rats is generally assumed, the morphological and functional characteristics of ovulation in immature rats have been scarcely considered. We describe herein the morphological aspects o

4. Excessive Ovarian Production of Nerve Growth Factor Facilitates Development of Cystic Ovarian Morphology in Mice and Is a Feature of Polycystic Ovarian Syndrome in Humans
Although ovarian nerve growth factor (NGF) facilitates follicular development and ovulation, an excess of the neurotrophin in the rodent ovary reduces ovulatory capacity and causes development of precystic follicles. Here we show that ovarian NGF production is enhanced in patients with polycystic ovarian syndrome (PCOS) and that transgenically driven overpro
