Chemotherapy resistance is the major reason for the failure of ovarian cancer treatment. One mechanism behind chemo-resistance involves the upregulation of multidrug resistance (MDR) genes (ABC transporters) that effectively transport (efflux) drugs out of the tumor cells. As a common symptom in stage III/IV ovarian cancer patients, ascites is associated with cancer progression. However, whethe...

An experiment was conducted to investigate the effect of different types of ovarian cycles on reproductive indices and blood metabolites in 61 Holstein cows. Blood samples were taken from each cow between day 12 and day 50 postpartum (PP). Serum progesterone concentrations were measured to determine the onset of luteal function and different types of luteal dysfunctions in cows. Serum glucose, ...

background: our preliminary data on the protein expression of sort1 in ovarian carcinoma tissues showed that sortilin was overexpressed in ovarian carcinoma patients and cell lines, while non-malignant ovaries expressed comparably lower amount of this protein. in spite of diverse ligands and also different putative functions of sortilin (ntr3), the function of overexpressed sortilin in ovarian ...

Knowledge of normal gonadal hormone production and function provides the basis for understanding the ovarian pathologic effects resulting from perturbations in endocrine balance and feedback. A precisely timed, complex, and well-coordinated cascade of ovarian steroidogenesis accompanies normal cyclical follicular function. This cascade involves both estrogens and androgens. Alterations in the h...

introduction: among the endocrine diseases, hypothyroidism is the commonest after diabetes.thyroid hormones (t3,t4) are essential for genital organs function. apoptosis process in ovarian cells plays a significant role of development in ovarian follicles. the aim of the present study was determine the apoptotic index induced by hypothyroidism in rat ovarian follicles. materials and methods: in ...

OBJECTIVE The present study aimed to determine the expression, roles and functional mechanisms of long non-coding RNA AFAP1-AS1 (AFAP1-AS1) in the progression of ovarian cancer. PATIENTS AND METHODS AFAP1-AS1 expression was assessed in ovarian cancer samples and ovarian cancer cell lines by quantitative real-time PCR. The association of AFAP1-AS1 expression with clinicopathological factors wa...

BACKGROUND Aggressive chemotherapy generally results in the loss of both endocrine and reproductive functions. For some women, however, oocyte, embryo or ovarian tissue cryopreservation were not proposed at the time. For three such women, orthotopic allotransplantation of fresh ovarian tissue from their genetically non-identical sister was performed. METHODS Three women, aged 20, 15 and 12 ye...

AIM To evaluate ovarian function after modern intensive multi-agent chemotherapy for osteosarcoma given during childhood or adolescence. METHODS After discontinuation of treatment, 10 female osteosarcoma survivors were followed up for 1.5-14 (median 4.6) years. Their age at diagnosis was a median of 12.9 (range 6-15) years and at the last follow up 18.6 (range 16-22). The main follow up inclu...

AIM To evaluate the effect of antitubercular therapy (ATT) on an ovarian function such as ovarian reserve, ovarian dimensions, and ovarian stromal blood flow. SETTINGS AND DESIGN Prospective study design. MATERIALS AND METHODS Fifty infertile women with female genital tuberculosis (FGTB) without tubo-ovarian masses diagnosed by positive acid-fast bacilli culture or epithelioid granuloma on ...
