1. INFLUÊNCIA DO HEPES NA MATURAÇÃO IN VITRO DE OÓCITOS CANINOS OBTIDOS DE CADELAS EM DIESTRO E ANESTRO
Resumo Diferentemente de outras espécies domésticas, a maturação in vitro (MIV) de oócitos caninos apresenta sucesso limitado. O objetivo deste estudo foi avaliar o efeito do HEPES na maturação in vitro de oócitos caninos obtidos de cadelas em diestro e anestro. Os ovários foram coletados, isolados assepticamente e transportados refrigerados a uma t

2. Evaluation of cell proliferation and endometrial thickness of bitches in different periods of diestrus
ABSTRACT This study aimed to determine the histological features of the endometrium of bitches, as well as the cell proliferation at specific moments of diestrus, 10, 20, 30, 40, 50 and 60 days post ovulation, correlating the endometrial thickness with the uterine cell proliferation and the metabolic state (weight, blood glucose and plasma cholesterol) of th

3. Modelo experimental de endometrite em vacas inoculadas com Escherichia coli inativada por meio de infusão uterina
The aim of this study was to evaluate the endometrial inflammatory response of nine Zebu cows inoculated through uterine infusion with 30 mL of inactivated Escherichia coli suspension (1 x 109 UFC/mL) and nine with 30 mL of sterile phosphate buffered saline. Endometrial biopsies were performed before and after the inoculations during estrus, and ten days lat

4. AÇÃO CENTRAL DA OCITOCINA NO CONTROLE DA INGESTÃO ALIMENTAR: influência do ciclo estral. / CENTRAL ACTION OF OXYTOCIN ON THE CONTROL OF FOOD INTAKE: influence of the estrous cycle.
In addition to stimulation of uterine contraction and milk ejection, oxytocin (OT) acts on neural circuits that control food intake. This study aimed to investigate the gonadal modulation of ocitocinergic control on food ingestion. Female Wistar rats with at least three regular cycles were monitored for 15 days and underwent implantation of cannula into the

5. Estrous cycle and stress: influence of progesterone on the female brain
The female brain operates in a constantly changing chemical milieu caused by cyclical changes in gonadal hormones during the estrous cycle (menstrual cycle in women). Such hormones are highly lipophilic and pass readily from the plasma to the brain where they can influence neuronal function. It is becoming clear that the rapid reduction in peripheral circula

6. Influência do ciclo estral no efeito do diazepam na ansiedade e memória de ratas
Memory and anxiety are related phenomena. Several evidences suggest that anxiety is fundamental for learnining and may facilitate or impair the memory formation process depending of the context. The majority of animal studies of anxiety and fear use only males as experimental subjects, while studies with females are rare in the literature. However, the preva

7. Expressão gênica da prolactina, do receptor de prolactina e das hialuronam sintases e a imunoistoquímica do ácido hialurônico e do receptor CD44 em úteros de camundongos fêmeas com hiperprolactinemia induzida pela metoclopramida, durante as fases do ciclo estral / Gene expression of the prolactin, of the prolactin receptor and of the hyaluronan synthases and immunohistochemistry of the hyaluronic acid and of the CD44 receptor in uterus of female mice with metoclopramide-induced hyperprolactinemia throughout the estrous cycle
OBJECTIVE: To evaluate the gene expression of prolactin, prolactin receptor and hialuronan sintase and immunohistochemistry of hyaluronic acid and CD44 in the uterus of female mice with metoclopramide-induced hyperprolactinemia throughout the estrous cycle. METHODS: 80 adult (100 days old) female virgin mice were randomly divided into two groups of 40 animal

8. EFEITO DA GENISTEÍNA NA FUNCIONALIDADE DE MACRÓFAGOS: UM ESTUDO COMPARATIVO ENTRE RATOS MACHOS E FÊMEAS
Genistein has estrogenic activity and can bind to estrogen receptors (ER), so it is considered a phytoestrogen. ER have been reported in macrophages and in that sense, the estrogens modulate immune responses. Despite the sexual dimorphism of the immune responses in females and males is well established, there are few studies that elucidate the role of bioact

9. Effect of urea in the diet on ovarian follicular dynamics and plasma progesterone concentration in Alpine goats
To evaluate the effect of using urea in the diet on ovarian follicular dynamics and plasma urea and progesterone concentration, an experiment was carried out with 29 Alpine goats randomly distributed into four diets, each one containing 0%; 0.73%; 1.46% or 2.24% of urea on total dry matter. The follicular dynamics was monitored daily by ultrasonography. The

10. Long-term melatonin treatment reduces ovarian mass and enhances tissue antioxidant defenses during ovulation in the rat
Melatonin regulates the reproductive cycle, energy metabolism and may also act as a potential antioxidant indoleamine. The present study was undertaken to investigate whether long-term melatonin treatment can induce reproductive alterations and if it can protect ovarian tissue against lipid peroxidation during ovulation. Twenty-four adult female Wistar rats,

11. Manipulation of ovarian and uterine function to increase conception rates in cattle.
In cattle, embryonic and fetal losses are the major causes of reproductive failureo Losses associated with failure in the process of maternal recognition of pregnancy can amount to as much as 30%0 Successful establishment of pregnancy depends on a delicate balance between luteolytic mechanisms inherent to the endometrium at the end of diestrus and antiluteol

12. 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
