13. Cistos ovarianos funcionais em usuarias de implantes contraceptivos liberadores de etonogestrel ou levonorgestrel
The objective of this study were to evaluate the prevalence of functional ovarian cysts in users of two contraceptive implants compared to users of intrauterine device (IUD) during the first year of use. A total of 344 women were enrolled at 3 months of use of the etonogestrel-releasing implant (Implanonâ), the levonorgestrel-releasing implant (Jadelleâ),

14. Effects of melatonin on the ovarian response to pinealectomy or continuous light in female rats: similarity with polycystic ovary syndrome
The current study was conducted to investigate the relationship between melatonin and chronic anovulation. Adult (3-4 months old) female Wistar rats were submitted to pinealectomy: group I: pinealectomized ovariectomized melatonin-treated (N = 10); group II: pinealectomized ovariectomized placebo-treated (N = 12); group III: pinealectomized light-treated pla

15. Combined effects of gonadotropin and flushing in pubertal gilts / Estudo dos efeitos combinados de gonadotrofinas e flushing em marrãs à puberdade
The objective of this study, held at the Swine Research Laboratory of the School of Veterinary Medicine and Zootechnology of the Univ. of São Paulo in Pirassununga, São Paulo, was to verify the combined effects of exogenic gonadotropin (eCG and LH) and flushing on the duration and dispersion of the manifestation of initial and second estruses, cyclicity of

16. Risk factors for seromucinous benign ovarian cysts in northern Italy.
STUDY OBJECTIVE: To analyse risk factors for seromucinous benign ovarian cysts. DESIGN: Between 1984 and 1994 a case-control study was carried out. Cases were 225 women aged less than 65 year with a histologically confirmed diagnosis of benign seromucinous ovarian cysts admitted to a network of obstetrics and gynaecology departments in Milan. Controls were a

17. Ovarian neoplasms, functional ovarian cysts, and oral contraceptives.
The incidence of ovarian neoplasms and functional ovarian cysts diagnosed at laparotomy or laparoscopy among the 17,000 women taking part in the Oxford Family Planning Association contraceptive study was investigated. Epithelial cancer of the ovary was only 25% as common among those who had ever taken oral contraceptives as those who had never done so (95% c

18. Abnormal steroid excretion in gestational trophoblastic disease complicated by ovarian theca-lutein cysts.
Serum and urine steroids were examined in two subjects with trophoblastic disease accompanied by large ovarian theca-lutein cysts and compared with those from 10 patients with trophoblastic disease but without palpable cysts. In the patients without cysts normal values were obtained for serum oestradiol, progesterone, 17 alpha-hydroxyprogesterone and androst

19. The Fusome Mediates Intercellular Endoplasmic Reticulum Connectivity in Drosophila Ovarian Cysts
Drosophila ovarian cysts arise through a series of four synchronous incomplete mitotic divisions. After each round of mitosis, a membranous organelle, the fusome, grows along the cleavage furrow and the remnants of the mitotic spindle to connect all cystocytes in a cyst. The fusome is essential for the pattern and synchrony of the mitotic cyst divisions as w

20. A case-control study of benign ovarian tumours.
STUDY OBJECTIVE--The aim was to investigate the association between reproductive, contraceptive, and menstrual factors and risk of benign ovarian tumours. DESIGN AND SETTING--This was a case-control study carried out in six London Hospitals. An interviewer administered questionnaire was used. SUBJECTS--62 women with a benign epithelial ovarian neoplasm, 37 w

21. Acetylcholinesterase and butyrylcholinesterase genes coamplify in primary ovarian carcinomas.
The genes for acetylcholinesterase (ACHE) and butyrylcholinesterase (CHE) are expressed in multiple tumor tissues, including ovarian carcinomas. Both CHE and ACHE genes coamplify in leukemias. To examine the relationship of gene amplification to the expression of these genes in tumors, ACHE and CHE genes and their expression were studied in primary ovarian c

22. Genetic and Molecular Characterization of P Element-Induced Mutations Reveals That the Drosophila Ovarian Tumor Gene Has Maternal Activity and a Variable Null Phenotype
The mutations in the ovarian tumor (otu) gene arrest oogenesis at several stages in development. A series of deletion mutations in the otu region were characterized, each of which causes the absence or reduction of the otu transcript. These alleles range from the most severe class, which results in ovaries lacking egg cysts, to relatively mild mutations that

23. Estrogens increase the expression of fibulin-1, an extracellular matrix protein secreted by human ovarian cancer cells.
Ovarian cancers have a high ability to invade the peritoneal cavity and some are stimulated by estrogens. In an attempt to understand the mode of action of estrogens on these cancer cells and to develop new markers, we have characterized estrogen-regulated proteins. This study was aimed at identifying a protein secreted by ovarian cancer cells whose level wa

24. Aberrant expression of homeobox gene HOXA7 is associated with müllerian-like differentiation of epithelial ovarian tumors and the generation of a specific autologous antibody response
Autologous serum antibodies to molecules that are aberrantly expressed in tumors represent potential biomarkers for early diagnosis of cancer. In this study, we identified the homeobox gene HOXA7 as encoding an antigen in epithelial tumors of the ovary. These tumors are thought to arise from the simple epithelium lining the ovarian surface, but they oft
