Background and Aims: Ovarian cancer is one of most common causes of cancer related women's mortalities. Human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. A few studies also identified HPV DNA in ovarian carcinoma tissues. However, some studies did not detect HPV DNA in ovarian carcinoma tissues. In this articl...
Background: Ovarian masses represent a range of pathology from benign cyst to highly aggressive malignant tumors. It has been estimated that gynecologic malignancy account for approximately 2% of all types of cancer in children, 60-70% of these lesions arise in the ovary. Methods: All ovarian masses which were resected or biopsied in Mofid Children's Hospital from 2002 to 2012 were reviewe...
Background and purpose: The purpose of this study was to determine the serum concentration of copper (Çu), zinc (Zn) and copper/zinc ratio (Çu/Zn) in patients with ovarian cancer to compare with those in patients with benign ovarian lesions. Materials and methods: This cross-sectional study was carried out on 50 patients with ovarian cancer (malignant group) and 50 patients with benign ova...
In vitro culture of human ovarian tissue the following cryopreservation is proposed for follicular development. There are no techniques that guarantee successful maturation of the follicles within the excised tissue. The viability of cultured human ovarian tissue improved by adding some growth factors to the culture media. The efficiency of vitrification as the cryopreservation method for human...
Background and Objective: Ovarian tumors are among the most frequent pathologic conditions in gynecologic practice and a frequent cause of hospitalization and surgery. The aim of this study was to determine histologic distribution of benign operated masses especially functional ovarian cysts. Material and Methods: Benign ovarian files of operated patients (2961 cases) in 20 tertiary and sec...
The ovarian reserve (OR) gradually decreases throughout the female fertile life. This continuous depletion in OR is irreversible. This occurs through a programmed cell death known apoptosis. Some factors hasten such depletion such as chemo- and radiotherapy. Others have been investigated in trials to preserve the OR including gonadotropins, cytokines, growth hormones, nitric oxide and reorganiz...
objective: to evaluate the potentiality of ovcar–3 cell line of ovarian adenocarcinoma as a xenograft model for ovarian adenocarcinoma in nude mice. materials and methods: the cell line isolated from advanced human ovarian adenocarcinoma, were inoculated to eight nude mice and two months later. established tumors were transferred to pathology laboratory to be prepared by h&e; staining and immun...
background : ovarian cancer is the leading cause of death among gynecological cancers. changes in the methylation of brca1 and brca2 may be an effective mechanism for breast and ovarian cancer. this study evaluates the protein expression and methylation status of brca2 in iranian patients. methods : we assessed 60 mullerian-type ovarian cancers by methylation-specific pcr assays and immunohisto...
results out of 140 samples of oca, 70 (50%) samples were malignant cancer and 70 (50%) were benign cancer as the control group. out of 70 malignant samples 25 (36.0%) were hpv-16 positive. 2.8% of the tissue samples of the control group were positive for hpv-16. conclusions these results show a feasible role of hpv-16 in the carcinogenesis of oca. according to these results, infection with hpv ...
background: acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. muc1 an integral membrane mucin is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. objective: the aim of this study was to evaluate the changes in muc1 expression of gravid mouse endometrium with and without hyperstimulation ...
