37. Desenvolvimento da próstata masculina e feminina do gerbilo da Mongólia submetido à exposição no período embriofetal e pós-natal de etinilestradiol / Development of male and female prostate of the Mongolian gerbil submitted to the exposure embryofetal period and postnatal ethinylestradiol
In males, prostatic morphogenesis is an event controlled by androgens, which act directly via paracrine factors secreted by the mesenchyme. In females, the embryological development of the prostate appears to occur in environment low levels of steroid hormones, but the presence of these hormones in the adult life induces differentiation and secretory activit

38. Oxidative stress and reproductive disorders in hyperglycemic male rats : antioxidant potencial of vitamins C and E / Relação entre estresse oxidativo e desordens reprodutivas em ratos machos hiperglicemicos : potencial antioxidante das vitaminas C e E
The hyperglycemia is related to disorders in the male reproductive system. When induced chemically, it can reduce the sexual hormones level, reproductive organs weight, sperm concentration, and fertility as well as the male rat sexual behavior. In men, the hyperglycemia can lead to sexual impotence, libido and spermatogenesis reduction. However, the main

39. Testicular morphology and morphometry in mice chronically exposed to arsenic / Morfologia e morfometria testicular de camundongos adultos submetidos à exposição crônica ao arsenato
There is an increasing concern about the potentially harmful effects of several environmental pollutants, as for instance, the inorganic arsenic, one of the main pollutants of the water worldwide. The intoxication by arsenic can be acute or chronic, and lead to a variety of pathologies and impairment of male reproductive system. This work aimed to investigat

40. Aspectos morfofuncionais da prostata feminina do gerbilo durante o cilco estral : estudos estruturais e caracterização do perfil secretor / Morphofunctional aspects of the gerbil female prostate during the estrous cycle : structural analysis and characterization on the secretory profile
The prostate is not an exclusive organ of the male reproduction system, found in females of several rodents species and also in humans. The female prostate has been considered homologue to the male ventral prostate and it is formed by a small cluster of glands and ducts inserted into a fiber muscular stroma. In adult female Mongolian gerbils (Meriones unguic

41. Aspectos relacionados à competência organogenética de meristemas caulinares de Dendrobium Second Love (Orchidaceae) / Aspects of Dendrobium second love shoot meristems (Orchidaceae) related to organogenetic competence
In vitro tissues, organs or plants culture has been widely used as a micropropagation technique aiming to study a number of factors involved in vegetable growth and development. In the present study, we evaluated the physiological conditions related to different vegetative or reproductive organogenetic responses in in vitro Dendrobium Second Love (Orchidacea

42. Evaluation of risk factors and prognosis criteria in severe maternal morbidity in obstetric ICU / Avaliação dos fatores de risco e criterios de prognostico na morbidade materna grave em UTI obstetrica
Introduction: In the last decade the identification of cases of severe maternal morbidity (SMM) has emerged as a promising complement or an alternative to the investigation of maternal deaths. The organic dysfunction is part of the continuum of SMM. Women admitted to intensive care units (ICU) during pregnancy or postpartum may be a good source of informatio

43. Gynecologic-tract sparing extra peritoneal retrograde radical cystectomy with neobladder
OBJECTIVE: We report on a series of female patients with transitional cell carcinoma of the bladder who underwent extraperitoneal retrograde radical cystectomy sparing the female reproductive organs with neobladder creation. MATERIALS AND METHODS: 14 female patients between the ages of 45 and 72 years who underwent gynecologic-tract sparing cystectomy (GTSC)

44. Análise da expressão de genes do tipo MADS-Box em plantas de reprodução sexual e apomítica de Brachiaria brizantha
Brachiaria genus has species containing sexual and apomictic plants. In apomictic reproduction, embryo sac differentiates from an unreduced cell and the embryo develops in absence of egg cell fertilization. MADS-Box genes are transcription factors that are involved in floral organ formation. The characterization of these homeotic genes in Brachiaria brizanth

45. Evaluation of postoperative complications in bitches submitted to ovariohysterectomy. / Avaliação das complicações pós-operatórias em cadelas submetidas à ovário-histerectomia.
This study aimed to evaluate the postoperative complications in 20 bitches previously submitted to ovariohysterectomy, correct these complications by surgery, and correlate the findings observed in preoperative diagnostic exams with those found during exploratory laparotomy. The animals were evaluated from the first day to the third month after consultation.

46. Análise morfológica das espermátides e dos espermatozóides de Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) nos tratos reprodutores
Diptera constitutes one of the four largest orders of insects. The Oriental latrine-fly Chrysomya megacephala (Fabricius) belongs to the family Calliphoridae and is associated with medic, veterinary, sanitary and forensic issues. The aim of this research was to characterize the utrastructural aspects of the spermiogenesis and spermatozoa of the C. megacephal

47. Evaluation of differents protocols of DNA extraction for Brucella abortus detection from aborted featus materials or from calves born from experimentally infected cows with 2308 strain / Avaliação de diferentes protocolos de extração de DNA para detecção de Brucella abortus a partir de materiais colhidos de feto abortado ou bezerros nascidos de vacas experimentalmente infectadas com a cepa 2308
Infection by Brucella abortus diminishes the reproductive efficiency in bovines and it is also the agent of one of the most spread zoonosis in the world. In many countries control programs aim this disease, and in Brazil its combat was better organized since 2001 with the creation of the national program by the Ministry of Agriculture, Livestock and Supplies
