Increased serum concentrations of aminoterminal propeptide of type III procollagen occur in advanced ovarian cancer. To study their origin, we compared the expressions of type I and type III procollagens in ovarian tumor tissue and the peritoneal cavity with immunoassays for the propeptide domains of these procollagens. Samples of tumor cyst fluid, peritoneal ascitic fluid, tumor vein blood, an...

BACKGROUND We used intensive modern proteomics approaches to identify predictive proteins in ovary cancer. We identify up-regulated proteins in both serum and peritoneal fluid. To evaluate the overall performance of the approach we track the behavior of 20 validated markers across these experiments. METHODOLOGY Mass spectrometry based quantitative proteomics following extensive protein fracti...

background & aim: ovarian torsion is one of the most common causes of emergency surgery in gynecology, with a tendency to occur in postmenopausal women. the aim of this study was to provide information concerning the clinical presentations, surgical management, pathological findings and risk of malignancy in postmenopausal women with ovarian torsion. methods:in this cross-sectional study, the r...

The first aim of the research conducted as part of this thesis was to investigate the expression and activities of 11PHSD enzymes in porcine mural granulosa cells and COCs from small, medium and large antral follicles, as well as from ovarian cysts. Both cloned lipHSD enzymes (11 PHSD 1 and 11PHSD2) were expressed in porcine granulosa cells however the results of the expression studies in COCs ...

Ultrasonography has been commonly used in the diagnosis of intraabdominal cysts like ovarian cysts. Massive ovarian cysts can mimic ascites clinically (a condition termed pseudoascites) and ultrasonographically and can cause delay in the diagnosis and management. Clinicians should therefore consider other differential diagnoses in cases of large intraabdominal fluid collection. We report such a...

OBJECTIVES The ovarian tumor microenvironment, ie, the peritoneal fluid, is an intriguing research subject. The goal of this study was to assess the behavior of selected cytokines and growth factors within the peritoneal fluid in pathologies associated with ascites and to assess the relationship between the levels of these substances and select prognostic factors of ovarian cancer. METHODS A ...

BACKGROUND In order to investigate whether gonadotrophin-releasing hormone (GnRH) antagonists exert a significant effect on steroid secretion in vivo compared with GnRH agonists, concentrations of sex steroid hormones (oestradiol, progesterone and testosterone) were studied in follicular fluid from women undergoing ovarian stimulation and treated with either GnRH agonist or antagonist. In addit...

Endoparasitic wasps are able to develop inside permissive host insects due to their ability to overcome or evade the host's immune system. In the present study, we provide experimental evidence that ovarian calyx fluid of the ichneumonid endoparasitoid Venturia canescens has the potential to alter host haemocyte spreading and inhibit host haemolymph melanisation due to the presence of a putativ...

The aim of this study was to trigger the expression of genes related to oocytes in putative ovarian stem cells scraped from the ovarian surface epithelium of women with premature ovarian failure and cultured in vitro in the presence of follicular fluid, rich in substances for oocyte growth and maturation. Ovarian surface epithelium was scraped and cell cultures were set up by scrapings in five ...

Cytokines are key modulators of the immune system and play an important role in the ovarian cycle. IL-18 levels in serum and follicular fluid were analyzed in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. The cohort study group consisted of 90 women, who were undergoing IVF or ICSI. The body mass index (BMI) was determined in all patients; I...
