25. Uso de protocolos de IATF para aumentar a eficiência reprodutiva de gado de corte / Use of TAI protocols to enhance reproductive efficiency of beef cattle
The technique of timed artificial insemination (TAI) can be used as a tool to optimize reproductive efficiency. Among the alternative protocols hormone, prostaglandin (PGF2α) and estradiol benzoate (EB) have been used frequently, or combined with progesterone and GnRH analogues. This work aimed to evaluate the influence of follicular diameter on the pre

26. Efeito do tratamento anti-inflamatÃrio na histologia endometrial, produÃÃo de prostaglandina e taxa de gestaÃÃo apÃs transferÃncia de embriÃes e/ou manipulaÃÃo cervical em Ãguas / Efeito do tratamento anti-inflamatÃrio na histologia endometrial, produÃÃo de prostaglandina e taxa de gestaÃÃo apÃs transferÃncia de embriÃes e/ou manipulaÃÃo cervical em Ãguas / Effect of anti inflammatory treatment in endometrial histology, prostaglandin production and pregnancy rates after embryo transfer and/or cervical manipulation in mares / Effect of anti inflammatory treatment in endometrial histology, prostaglandin production and pregnancy rates after embryo transfer and/or cervical manipulation in mares
Embryo transfer is currently the main breeding tool in equine reproduction. However it is still necessary to improve pregnancy to lower its costs.Among many factors that influence ET results, recipient mare management should be underlined. Currently the method utilized is non surgical transcervical transfer. Equine ET professionals observed that the less cer

27. Prostaglandina F2 alfa associada à ocitocina ou carbetocina na indução de partos em suínos / Prostaglandin f2 alpha associated with oxytocin or carbetocin in induction on parturition in swines
O presente estudo teve como objetivo avaliar a aplicação de análogo sintético da prostaglandina F2 (PGF2 ) associado à carbetocina ou ocitocina sobre a eficiência na indução ao parto em suínos. Foram analisados o tempo entre aplicação e início do trabalho de parto, duração do parto e percentual de natimortalidade. A indução do parto foi reali

28. Meloxicam and melatonin: did they trigger a synergic action during the acute phase of the experimental infection with Trypanosoma cruzi? / Meloxicam e melatonina: teriam uma ação sinérgica durante a fase aguda da infecção experimental por Trypanosoma cruzi?
The modulation of the immune responses in experimental models infected with Trypanosoma cruzi has effectively contributed for the investigations of new therapies used to treat Chagas disease. In this study, it was evaluated the production of Th1 and Th2 cytokines, which play a role during the acute phase of the disease, as well as prostaglandin E2 and nitrit

29. Estudo dos efeitos do laser infra-vermelho (810nm) no modelo de inflamação aguda induzida em joelho de ratos. / Study of the effects of near-red laser (810nm) on acute inflammation of the knee in rats.
Introduction. Arthritis of the knee (AK) is the most common type of osteoarthritis, and its prevalence is rising in parallel with the increasing age of the population.. Here we investigate the effects of Low Level Laser Therapy (infra-red, 810 nm) in experimentally induced rat knee osteoarthritis. Methods. Male wistar rats (150 200g) were anaesthetized with

30. Investigation of adenosine endogenous increase decurrent of D-Frutose-1,6-difosfato administration, a glycolytic intermediate. / Investigação do aumento endógeno de adenosina decorrente da administração do intermediário glicolítico D-Frutose-1,6-difosfato
D-Fructose-1,6-bisphosphate (F1,6BP), a high-energy glycolytic pathway intermediate, is reported to have a many pharmacologically effect, but its underlying mechanism of action in inflammation is incompletely understood. In this study, the aim was to examine the function of F1,6BP on cytokines and adenosine. Then, the possible F1,6BP anti-inflammatory activi

31. Mediadores envolvidos na resposta febril induzida pela RANTES / Mediators involved in the febrile response induced by RANTES
Em estudo anterior, observamos que o Met-RANTES, antagonista de receptores CCR1 e CCR5 para quimiocinas, injetado pela via endovenosa (i.v.) reduziu a resposta febril induzida pelo lipopolissacarídeo (LPS) de E. coli, demonstrando o envolvimento da quimiocina RANTES (Regulada sob ativação, expressa e secretada por células T normais) nesta resposta. Além

32. 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

33. Efeitos das isoflavonas da soja (Glycine max) na síntese de fatores vasoativos derivados de células endoteliais humanas da linhagem ECV304 / Effects of soy isoflavones (Glycine max) in the synthesis of vasoactive factors derived from human endothelial cells line ECV304.
During their reproductive years, women have a lower incidence of coronary heart disease (CHD) compared to men of similar age. However, this advantage disappears in post-menopause, suggesting that female sex hormones exert some cardio protective effect. One of the mechanisms proposed to explain this protection is the fact that estrogens promote the production

Efeito do exercício de força em diferentes intensidades com volume total similar sobre a dor muscular de início tardio, marcadores de lesão muscular e perfil endócrino. / The effect of different resistance exercise intensities with similar total volume upon delayed on set muscle soreness, muscle damage markers and hormonal profile.
Este estudo compara quatro diferentes intensidades com o volume total similar no exercício supino. Avaliou-se a dor muscular de início tardio (DMIT), atividade de creatina quinase (CK), as concentrações sangüíneas de interleucina (IL)-1b, IL-6, fator de necrose tumoral-a (TNF-a), prostaglandin

35. Emprego tópico de prostaglandina da família E ou de análogo com o intuito de acelerar a migração de embriões eqüinos para o útero e imunolocalização dos respectivos receptores / Topic application of prostaglandin E family or analogous aiming the acceleration of the migration of equine embryos to the uterus and immunolocalization of the respective receptors
Differently of any other ways of occurrence among the domestic animals, concerning mares, their embryos migrate in a delayed lapse of time to their uterus due to a correlation to the PGE2. Consequently, one extracts embryos which are already into some more advanced phase of their development (blastocyst and expanded blastocyst) normally exceeding 300 microme
