13. Diferentes protocolos de estimulação ovariana para a produção de oócitos em cabras da raça Canindé. / Different ovarian stimulation protocols for oocyte production in goats Canindé.
Este estudo analisou o efeito de diferentes tratamentos hormonais de estimulação ovariana sobre a quantidade e a qualidade dos complexos cumulus-oócitos (CCO) recuperados por laparoscopia e sua posterior maturação in vitro (MIV) oriundos de cabras Canindé em risco de extinção. Dezoito cabras Canindé cíclicas receberam o tratamento que consistiu de

14. RT-PCR QUANTITATIVO EM TEMPO REAL PARA ANÁLISE DO RECEPTOR DE EGF EM COMPLEXOS CUMULUS-OÓCITO COLHIDOS POR LAPAROSCOPIA EM CABRAS CANINDÉ SUBMETIDAS À ESTIMULAÇÃO HORMONAL OVARIANA
Ovarian stimulation with exogenous Follicle Stimulating Hormone (FSH) has been used to increase the number of viable oocytes for laparoscopic oocyte recovery (LOR) in goats. The aim of this study was to evaluate the effect of two FSH protocols for ovarian stimulation in goats on the expression pattern of EGF receptor (EGFR) in cumulus-oocyte complexes (COCs)

15. Técnica laparoscópica versus técnica aberta para adrenalectomia experimental em suínos / Laparoscopic techniques versus open technique for swines in experimental adrenalectomy
Adrenalectomy is a highly complex surgical procedure. In order to perform it, surgeons must have a profound knowledge of the anatomophysiologic aspects of the adrenal glands, especially their vascular diversity, as well as full understanding of diagnostic means so as to properly identify their diseases. Open adrenalectomy is the most widely used method in ve

16. EXPRESSÃO DAS MAPKs EM FOLÍCULOS OVARIANOS E CORPOS LUTEOS EM DIFERENTES FASES DO CICLO ESTRAL DE BOVINOS / EXPRESSION OF MAPKs IN ovarian follicles is Lutea at different stages of estrous cycle CATTLE
Bovine estrous cycle activates the pathways of MAPKs (mitogen activated protein) via oscillation of hypothalamus-pituitary-gonad axis hormones. The objective of this work was to evaluate in vivo the frequency of expression of active (phosphorylated) form, of p-MEK 1/2 and p-ERK1/2 in all types of ovarian follicles and corpora lutea in different phases of the

17. Transplante autólogo de tecido ovariano para o peritônio de ratas após congelamento e descongelamento
One of the major problem against reproductive medicine is the incapacity of oocyte preservation. In these cases, ovary preservation could restore hormonal e fertility capacity. Objective: Assess the ovarian function after removal of the ovaries, cryopreservation and intraperitoneal autotransplantation. Design: Prospective experimental study involving 67 rats

18. HORMONAL STRATEGIES FOR ESTRUS INDUCTION/SYNCHRONIZATION IN 12-14 MONTHS OLD BEEF HEIFERS / ESTRATÉGIAS HORMONAIS DE INDUÇÃO/SINCRONIZAÇÃO DE ESTRO EM NOVILHAS DE CORTE ENTRE 12 E 14 MESES DE IDADE
The aim of this study was to develop and evaluate two protocols for estrus synchronization and/or induction in 12-14 months old beef heifers, which would allow the use of timed artificial insemination (TAI) after a short period of estrus detection (48h). The first experiment consisted of evaluating whether eCG was a necessary component in the BioRep system t

19. The influence of stress on nociception induced in temporomandibular joint / A influencia do estresse sobre a nocicepção induzida na articulação temporomandibular
Recent studies have investigated he role of psychological factor in temporomandibular disorders (TMD). However, the mechanisms responsible for nociceptive changes induced by stress are not established. Thus, the aim of this study was to evaluate the effect of acute, sub-chronic and chronic stress on nociception induced by formalin injection in rats? temporom

20. SincronizaÃÃo do estro e da ovulaÃÃo em novilhas girolandas: comparaÃÃo entre os protocolos hormonais âcidr-bâ e âovsynch / Synchronization of estrus and ovulation in heifers girolandas: comparison between the protocols hormonal "cidr-b" and "ovsynch
Avaliou-se a eficiÃncia de dois protocolos de induÃÃo e sincronizaÃÃo do estro e da ovulaÃÃo (âCIDR-Bâ âOVSYNCHâ) em 90 novilhas acÃclicas da raÃa Girolanda. Os animais foram distribuÃdos em trÃs grupos, onde o primeiro (n=30) foi submetido ao protocolo âOVSYNCHâ, que consiste na aplicaÃÃo intramuscular (IM) de 1,0ml de GnRH, sete dias dep

21. Study of psychological aspects and its implications for the occurence of hypertension during pregnancy / Estudo dos aspectos psicológicos e sua influência no desenvolvimento da hipertensão gestacional
The pregnancy is one of the most critical stages of the human development not only for women but also men. Thats a transient moment of the existency that requires a personal adjustments in various aspects of life. This, showing the necessity of a change of identity as well as reevaluation of roles. During pregnancy, there are peculiar emocional status and a

22. Influence of dexamethasone and weight loss on the regulation of serum leptin levels in obese individuals
The adipocyte hormone leptin is thought to serve as a signal to the central nervous system reflecting the status of fat stores. Serum leptin levels and adipocyte leptin messenger RNA levels are clearly increased in obesity. Nevertheless, the factors regulating leptin production are not fully understood. The aim of this study was to determine the effects of i

23. Influencia do treinamento fisico aerobio sobre as respostas cardiovasculares e respiratorias em mulheres na menopausa com e sem terapia de reposição hormonal
Menopause is a physiological condition in women?s life that occurs around the age of 45 to 52; it is responsible for progressive physical and psychological changes. These changes are generated by the reduction of progesterone and estrogen hormones and also modify the control of autonomic nervous system an the heart. The purpose of this study was to evaluate

24. Influencia do ciclo estral sobre as respostas hormonais de ratas submetidas a estresse
Right atria isolated from female rats submitted to three footshoek or swimming sessions showed changes on sensitivity to eateeholamines, when the stress sessions were applied during estrus, metestrus and diestrus (Diestrus Group), without changes when they were applied at diestrus, proestrus and estrus (Estrus Group). The aim of this work was to analyse the
