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. 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

4. 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

5. Relationships between female infertility and female genital infections and pelvic inflammatory disease: a population-based nested controlled study
OBJECTIVES: Our purpose was to examine the associations of female genital infections and certain comorbidities with infertility. METHODS: The Taiwan National Health Research Database was searched for women with a new diagnosis of infertility between 2000 and 2013. Women without a diagnosis of infertility served as a control group and were matched with the

6. Immunhistochemical analysis of Nuclear Factor Kappa Beta expression in etiopathogenesis of ovarian tumors
Abstract Purpose: To investigate the place of the transcription factor nuclear kappa B (NF-kB), which is a marker of chronic inflammation, in the etiology of the ovarian carcinoma. Methods: NFkB analysis with the immunohistochemical method has been performed. To evaluate immunohistochemical NF-kB expression in the ovarian tissue, the H-score method. H-scor

7. Anethole reduces oxidative stress and improves in vitro survival and activation of primordial follicles
Primordial follicles, the main source of oocytes in the ovary, are essential for the maintenance of fertility throughout the reproductive lifespan. To the best of our knowledge, there are no reports describing the effect of anethole on this important ovarian follicle population. The aim of the study was to investigate the effect of different anethole concent

8. Systemic administration of curcumin nanoparticles protects ischemia-reperfusion injury in ovaries: An animal model study
Summary Objective: Ovarian torsion must be diagnosed and treated as early as possible. The aim of the present study was to investigate the effects of intraperitoneal administration of nanocurcumin on ischemia-reperfusion injury in ovaries. Method: Thirty-five (35) healthy female Wistar rats weighing approximately 250 g were randomized into seven experiment

9. Allogeneic mesenchymal stem cells and xenogenic platelet rich plasma, associated or not, in the repair of bone failures in rabbits with secondary osteoporosis
Abstract Purpose: To assess the efficacy of allogeneic mesenchymal stem cells and xenogenic platelet rich plasma in the treatment of bone failure of osteoporotic rabbits secondary to estrogenic deprivation and iatrogenic hypercortisolism. Methods: Eight female rabbits underwent ovarian resection and corticoid therapy to induce clinical status of osteoporos

10. Increased expression of ID2, PRELP and SMOC2 genes in patients with endometriosis
Endometriosis is a benign, estrogen-dependent disease with symptoms such as pelvic pain and infertility, and it is characterized by the ectopic distribution of endometrial tissue. The expression of the ID2, PRELP and SMOC2 genes was compared between the endometrium of women without endometriosis in the proliferative phase of their menstrual cycle and the eut

11. Relationship between matrix metalloproteinases and the occurrence and development of ovarian cancer
Ovarian cancer is one of the most malignant genital cancers, with a high mortality rate. Many researchers have suggested that matrix metalloproteinases (MMPs) have remarkably high expression in ovarian cancer tissues. MMPs are considered to be related to the occurrence, development, invasion and metastasis of ovarian cancer. Moreover, some studies have disco

12. The beneficial effects of Montelukast against 2,3,7,8-tetrachlorodibenzo- p -dioxin toxicity in female reproductive system in rats
ABSTRACT PURPOSE: To determine the toxic effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on reproductive system and the beneficial effects of Montelukast (ML) with histological and biochemical analysis. METHODS: Rats were randomly divided into four equal groups (control, TCDD, ML and TCDD+ML). Tissue samples were collected on day 60 and oxidative sta
