Abstract:

ABSTRACT Squamous metaplasia of the rete ovarii is an ovarian pathologic change characterized by replacement of the normal single layered cuboidal epithelium of the rete ovarii by a stratified squamous keratinized epithelium. Uterus and ovaries from a local slaughterhouse pregnant crossbreed cow were evaluated through ultrasound, macroscopically and histologically. Grossly, there were multiple cysts in both ovaries, which were histologically characterized as rete ovarii cysts with squamous metaplasia and intraluminal accumulation of keratinized material. Squamous metaplasia of the rete ovarii

Abstract:

Opioid binding protein/cell adhesion molecule-like gene (OPCML) is frequently inactivated in epithelial ovarian cancer, but the role of this membrane protein in normal reproductive function is unclear. The ovarian surface epithelium (OSE) is thought to be the cell of origin of most epithelial ovarian cancers, some of which arise after transformation of OSE cells lining ovarian inclusion cysts, formed during ovulation. We used immunohistochemistry, immunoblotting and quantitative RT-PCR (qRT-PCR) to investigate OPCML expression in the uteri and ovaries of cycling 3-month CD-1 mice, as well as i

Cystic ovaries were found at necropsy in 54 of 71 (76%) female guinea pigs between 18 and 60 months of age. Histologic appearance and location of the cysts within the ovary were consistent with cystic rete ovarii. Microscopic appearance of the large ovarian cysts suggested reproductive performance in these guinea pigs should be compromised. Breeding records indicated that fertility was markedly reduced in affected females over fifteen months of age. Cystic endometrial hyperplasia, mucometra, endometritis in appropriate placental tissue, or fibroleiomyomas were seen in 21 of 54 (39%) guinea pig

A slaughterhouse study commissioned by Florida Cattleman’s Association in 2007 identified ovarian follicular dysplasia (OFD) as a primary cause of infertility in Florida beef cows.

Abstract:

Ovarian cysts are one of the most common forms of reproductive disease affecting women. Cyst or tumor is a form of abnormality that can be regarded as a benign growth of smooth muscle cells in the ovaries. Cysts are usually harmless but do not rule out the possibility of a malignant cyst or even turn into cancer. The thing that makes ovarian cysts dangerous is when they burst, are very large, or block the blood supply to the ovaries. Lack of knowledge of the general public about the symptoms that cause ovarian cyst disease makes it too late to detect this disease early so it is slow in handlin

Abstract:

Struma ovarii is a rare type of ovarian teratoma primarily composed of over 50% thyroid tissue. Its occurrence is reported in 2–5% of all ovarian teratomas, with approximately 0.5% to 10% showing malignant transformation. Managing it during pregnancy poses significant challenges as pregnancy can promote the growth of malignant struma ovarii due to elevated levels of ovarian and pregnancy-related hormones, including estrogen, progesterone, and human chorionic gonadotrophin (hCG). Most ovarian tumors, including struma ovarii, are detected during routine ultrasonography in the first and second tr

Abstract:

Struma ovarii is a rare dermoid tumor of the ovary (1% of all ovarian tumors and 2,7% of ovarian teratomas), with more than 50% of the overall tissue being thyroid. Approximately one third of the cases present ascites. Pseudo-Meigs syndrome has been reported in fewer than 10 cases and 5-8% present thyroid hyperfunction. However, only 26 cases reported the association of ascites or pseudoMeigs’ syndrome, elevated cancer antigen 125 and benign struma ovarii in the literature. The authors submit a case of benign struma ovarii that presented as a pelvic mass with ascites and highly elevated CA 125

Background. We previously found that expression of SET gene was up-regulated in polycystic ovaries by using microarray. It suggested that SET may be an attractive candidate regulator involved in the pathophysiology of polycystic ovary syndrome (PCOS). In this study, expression and cellular localization of SET protein were investigated in human polycystic and normal ovaries.Method. Ovarian tissues, six normal ovaries and six polycystic ovaries, were collected during transsexual operation and surgical treatment with the signed consent form.

Abstract:

Ovaries can be used in place of gametes as a resource for cryopreservation. Thus far, we have shown that in the Syrian hamster, pups can be successfully produced through the transplantation of fresh and cryopreserved ovaries. In this study, we attempted to simplify the ovarian cryopreservation procedures to facilitate the easy application of these techniques. In particular, the procedure would be easier and quicker if the ovaries did not have to be cut into small pieces before ovarian cryopreservation. Therefore, we examined the effects of ovarian fragment size on subsequent offspring producti

Ovarian monodermal teratoma containing thyroid tissue is a rare tumor. Authors reviewed the records of 94 patients operated for ovarian teratoma in their department between 1986 and 2002, of which 3 patients proved to have struma ovarii. They found that the 3 patients had highly variable clinical symptoms and morphological characteristics including tumor size, pain as main symptom, and the presence or absence of ascites and hormonal activity. It is concluded that struma ovarii appears to be poorly diagnosed, but an extensive histological examination may increase the diagnostic efficacy. Orv. H

To identify the ERβ-regulated genes that may control ovarian primordial follicle activation, we analyzed the transcriptome profiles of ErβKO rat ovaries collected on postnatal days 4.5, 6.5, and 8.5. Compared to wildtype ovaries, ErβKO ovaries displayed dramatic downregulation of Indian hedgehog (Ihh) expression. IHH-regulated genes, including Hhip, Gli1, and Ptch1, were also downregulated in ErβKO ovaries. This was associated with a downregulation of steroidogenic e

ABSTRACT Background Struma ovarii is a rare ovarian neoplasm, which contains thyroid tissue. It accounts for less than 5% of ovarian teratomas. These are mostly benign, occurring between 40 years and 60 years of age. Clinical and radiological features are inconclusive and mostly it is diagnosed by histopathology. About 5–8% cases have hyperthyroidism. Cystic struma ovarii is very rare with only 25 cases reported till now. It creates confusion in diagnosis, as even in histopathology, the cells are mostly like those resembling other cystic ovarian tumors with minimal thyroid follicles. Case desc

Ovarian aging hampers in vitro fertilization in assisted reproductive medicine and has no cure. Lipoprotein metabolism is associated with ovarian aging.

This study investigated whether upregulation of LDLR expression using lovastatin enhances ovarian activity in mice. We performed superovulation using a hormone and used lovastatin to upregulate LDLR.

Abstract In Siberian hamsters, exposure to short days (SDs, 8 h light:16 h dark) reduces reproductive function centrally by decreasing gonadotropin secretion, whereas subsequent transfer of photoinhibited hamsters to stimulatory long days (LDs, 16 L:8 D) promotes follicle stimulating hormone (FSH) release inducing ovarian recrudescence. Although differences between SD and LD ovaries have been investigated, a systematic investigation of the ovarian transcriptome across photoperiod groups to identify potentially novel factors that contribute to photostimulated restoration of ovarian function had

A. eschrichtii have a predominantly 2-year life cycle (from embryo to adult death) and reproduce once between late winter or early spring at the age of 2 years.
