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 Method...

Objective: To investigate the significance of neutrophil gelatinase-associated lipocalin (NGAL) and matrix metalloproteinase-9 (MMP-9) protein expression in epithelial ovarian cancers. Methods: NGAL and MMP-9 serum and ovarian tissue levels were detected in 150 ovarian epithelial cancers. 42 benign ovarian tumors and 30 healthy women as controls by immunohistochemistry technique and reverse tra...

Transplantation of cryopreserved ovarian tissue is a technology that holds promise for preserving reproductive potential for the future. It may be apropos for cancer survivors who will undergo treatment with sterility-inducing chemotherapy or radiation. Although there is some evidence suggesting cellular and molecular injury with the freezing and thawing process, there are examples in both anim...

leydig cell tumor as a sex-cord stromal tumor is a relatively uncommon ovarian tumorin bitch. a 10-year-old female german shepherd dog was presented because of protrusion of a large tumor-like mass of 16 × 14 × 7 cm in dimensions from her vagina. after stabilization of the patient, the mass was removed surgically and concurrent ovariohysterectomy was also performed. macroscopically, the healthy...

This study examined the association of CD44V6 expression in ovarian cancer. We recruited 38 patients with ovarian cancer, 23 with benign ovarian tumor, and 20 with normal ovaries using RT-PCR and western block analysis. Compared with normal ovaries, the expression of CD44V6 mRNA was significantly elevated in benign ovarian tumor and ovarian cancer. At the protein level, we found no significant ...

In this issue of Blood, Greve et al report that ovaries from leukemia patients in complete remission do not appear to contain viable malignant cells, in contrast to ovarian tissue retrieved before chemotherapy.1 This paper raises a number of questions because 3 different teams (Meirow et al,2 Rosendahl et al,3 and Dolmans et al4) have so far demonstrated by PCR that ovarian tissue from leukemia...

Cryopreservation of ovarian tissue has been proposed for storing gametes of young patients at high risk of premature ovarian failure. Autotransplantation has recently provided some promising results and is still the unique option to restore ovarian function from cryopreserved ovarian tissue in humans. In this article, we analyse data from the combined orthotopic and heterotopic transplantation ...

With the evolution of the treatment of malignant neoplasms, the survival rates of patients undergoing chemo- or radiotherapy are increasing. The continuous development of techniques of assisted human reproduction has led to important strategies in an attempt to maintain reproductive function in patients subjected to treatment of neoplastic diseases, among them cryopreservation of embryos, gamet...
