1. Relationships between antral follicle counts and ovarian morphology of Bos indicus of different ages
RESUMO O presente estudo teve como objetivo avaliar a relação entre a contagem de folículos antrais (CFA) e a morfologia ovariana de Bos indicus em diferentes faixas etárias: 12-23 meses (G1), 24-35 meses (G2), 36-47 meses (G3), 48-59 meses (G4) e >60 meses (G5). Os ovários foram coletados individualmente e enviados ao laboratório, onde suas caracterí

2. Morphological description of ovary and uterus of the nurse shark (Ginglymostoma cirratum) caught off at the Fortaleza coast, Northeast Brazil
RESUMO: O tubarão-lixa, Ginglymostoma cirratum (Bonnaterre, 1778) é uma das espécies mais estudadas de elasmobrânquios. O conhecimento de sua biologia reprodutiva, no entanto, ainda é relativamente raro, particularmente no Oeste do Atlântico Sul. Este estudo objetivou a descrição morfológica do útero e ovário de G. cirratum, baseado em espécimes

3. Growth and Differentiation Factor-9 Supplementation Affects Viability and Morphology of Preantral Follicles in Equine Ovarian Fragments During Short-term in vitro Culture
Abstract This study aimed to evaluate different concentrations of growth and differentiation factor-9 (GDF-9) on the development and maintenance of equine preantral follicle morphology during short-term in vitro culture. Ovaries (n=5) from five mares were collected from a local slaughterhouse and transported to the laboratory, where nine fragments (5x5x1mm)

4. Powdered coconut water (ACP 406®) as an alternative base culture medium for in vitro culture of goat preantral follicles enclosed in ovarian tissue
Abstract This study evaluated a powdered coconut water solution (ACP 406®) as a base culture medium on the in vitro survival and development of in situ goat preantral follicles. The ovarian fragments were either immediately fixed in Carnoy solution (non-cultured control) or individually cultured for 2 or 6 days. The following culture media (all containing 1

5. Growth hormone on ovarian morphology of lambaris (Astyanax bimaculatus) after induced spawning
RESUMO: O Lambari Astyanax bimaculatus é um peixe ovíparo de desova múltipla que é reprodutivamente ativo durante todo o ano, o que o torna promissor para cultivo e pesquisa. Este trabalho avalia histologicamente os ovários de lambaris submetidos à desova artificial, induzida pelo extrato hipofisário (grupo controle) e o efeito do hormônio de cresci

6. Quality control and characterization of the testicles and ovaries of irradiated Anastrepha obliqua from Brazil
ABSTRACT: With the aim of making the application of the Sterile Insect Technique (SIT) feasible in the management of the West Indian fruit fly in Brazil, Anastrepha obliqua (Macquart) (Diptera: Tephritidae), a number of quality parameters required by the SIT were investigated in this study. The aim was to verify the influence of a range of doses of gamma rad

7. DNA damage and primordial follicle activation after in vitro culture of sheep ovarian cortex in Morus nigra leaf extract
RESUMO: Este estudo avaliou o efeito do extrato das folhas de Morus nigra, com ou sem suplementos, sobre a morfologia, a ativação e o dano ao DNA de folículos pré-antrais cultivados inclusos em tecido ovariano. Os ovários foram coletados e divididos em fragmentos, sendo um fixado para análise histológica e ensaio de marcação de terminações dUTP me

8. Ovarian Morphology and Egg Quality Traits of Egyptian Selected Strain for Egg Production Compared with Commercial Laying Strains
ABSTRACT An experiment was conducted to evaluate the effect of selection for egg production performance of Cairo L-2 strain, as a local layer strain, after five generations of selection on productivity, ovarian morphology and some egg quality traits versus commercial Lohmann Brown-Lite (LBL) strain. The performance in the 5th generation was evaluated in Cair

9. Evaluation of ovarian structures using computerized microtomography
ABSTRACT Visualization and clear understanding of the ovarian structures are important in determining the stage of oestrus, helping to diagnose several pathologies and supporting advances in reproductive technologies. In this research, computerized microtomography (microCT) was used to explore and characterize the ovarian structure of seven mammalian species

10. Ovarian follicular cycle of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata: Tropiduridae) in a semiarid region of Brazil
The reproductive cycle of Squamata reptiles is often associated with environmental conditions, such as rainfall. In this respect, seasonal variations may affect the morphology of the ovarian follicles, which are associated with vitellogenesis. The present study describes histological alterations in the ovarian cycle of two lizard species, Tropidurus hispidus

11. Culture of bovine ovarian follicle wall sections maintained the highly estrogenic profile under basal and chemically defined conditions
Follicle cultures reproduce in vitro the functional features observed in vivo. In a search for an ideal model, we cultured bovine antral follicle wall sections (FWS) in a serum-free defined medium (DM) known to induce 17β-estradiol (E2) production, and in a nondefined medium (NDM) containing serum. Follicles were sectioned and cultured in NDM or DM for 24 o

12. AVALIAÇÃO DA MORFOLOGIA E VIABILIDADE DE FOLÍCULOS PRÉ-ANTRAIS OVINOS APÓS CRIOPRESERVAÇÃO E CULTIVO IN VITRO DE CURTA DURAÇÃO / EVALUATION OF MORPHOLOGY AND VIABILITY OF PREANTRAL FOLLICLES CRYOPRESERVATION SHEEP AFTER IN VITRO AND SHORT TERM
A criopreservação de tecido ovariano tem como principal objetivo a manutenção deste tecido para sua posterior utilização, garantindo a preservação do material biológico de mulheres e fêmeas de animais de alto valor genético. Embora a criopreservação de tecido ovariano seja extensamente estudada, diversos pontos ainda necessitam ser elucidados, c
