The effect of atrazine and linuron, the popular and widely used chlorinated herbicides, on both myometrial contractions and secretory functions of bovine uterus and ovaries in vitro, was investigated. The pesticides inhibited (P<0.05) the basal and oxytocin (OT)-stimulated myometrial strips contractions, as well as the effect of OT on secretion of prostaglandins (PGs: PGF2α and PGE2) from endometrium. But only linuron inhibits the effect of OT on myometrial contractions. Neither of herbicides affected PGs secretion from myometrium and PGF2α from endometrium...

PURPOSE: Extensive follicle loss has been demonstrated in ovarian grafts post transplantation, reducing their productivity and lifespan. Several mechanisms for this loss have been proposed, and this study aims to clarify when and how the massive follicle loss associated with transplantation of ovarian tissue graft occurs. An understanding of the mechanisms of follicle loss will pinpoint potential new targets for optimization and improvement of this important fertility preservation technique...

Measurement of Luteinizing hormone (LH) levels is of great importance in guidance for pregnancy, diagnosis of ovarian diseases and evaluation of clinical effect. Gold immunochromatographic strip(GICS) assay is a rapid, simple, low-costs, and on-site technology. Quantitative detection of GICS has advantage over the traditional qualitative or semi-quantitative strip assay. In this paper, we developed a novel quantitative detection method for GICS based on smart-phone. First, smart-phone was used to acquire GICS image...

Neuroendocrine carcinoma (NEC), also called small cell carcinoma or large cell carcinoma, is a rare and aggressive tumor that develops mainly in the lung and intestine. More rarely, NEC develops in gynecologic organs, with poor prognoses. We experienced a case of NEC in the broad ligament of the uterus. The patient was a 74-year-old woman with symptoms of abdominal distension and constipation. Ultrasound sonography detected an abdominal tumor larger than 10 cm. She was then admitted to our hospital. She underwent surgery under the diagnosis of ovarian cancer, but the bilateral ovaries and uterus were normal in appearance, and a tumor was developing instead from the broad ligament of the uterus...

BACKGROUND/AIM: Ovarian cancer remains one of the most commonly encountered malignancies affecting women worldwide, that is unfortunately commonly diagnosed in advanced stages of the disease. In these stages, the tumoral process usually involves the surrounding viscera throughout contiguity or induces the apparition of distant metastases via peritoneal, lymphatic or hematogenous spread, multiple resections being needed in order to achieve a good control of the disease. PATIENTS AND METHODS: In the present study, we present a case series of 12 patients in whom various surgical procedures on the rectosigmoidian loop were performed in order to achieve debulking surgery to no residual disease...

BACKGROUND: Immature ovarian teratoma is very rare in childhood. We are reporting 12 yo female with immature ovarian teratoma who presented initially with syndrome of inappropriate antidiuretic hormone. CASE: A 12 yo female presented with acute abdomen and distention. Initial laboratory tests showed hyponatremia (sodium -123 mmol/L), that did not respond to fluid management. Computerized tomography showed a 15 cm x 9 cm x 20 cm mass in the right ovary with multifocal internal fat, and dystrophic calcifications...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

Sex is determined by temperature during embryogenesis in snapping turtles, Chelydra serpentina. Previous studies in this species show that dihydrotestosterone (DHT) induces ovarian development at temperatures that normally produce males or mixed sex ratios. The feminizing effect of DHT is associated with increased expression of FoxL2, suggesting that androgens regulate transcription of FoxL2. To test this hypothesis, we cloned the proximal promoter (1.6kb) and coding sequence for snapping turtle FoxL2 (tFoxL2) in frame with mCherry to produce a fluorescent reporter...

BACKGROUND: Freezing strips of ovarian cortex before chemotherapy followed by transplantation is an experimental method to preserve fertility for reproductive-aged women with cancer. We report a case of a cancer patient who developed a mucinous cystadenoma in a grafted piece of ovarian cortex. CASE: A 32-year-old woman with a Ewing sarcoma had ovarian cryopreservation using cortical strip freezing before receiving chemotherapy. Five years later she had no ovarian function, and the strips were thawed and grafted back onto the ovary...

INTRODUCTION: Endometriomas are present in up to 44% of all women with endometriosis and have a detrimental effect on fertility. However, it is controversial whether endometriomas should be surgically removed before assisted reproduction technology. Our purpose was to evaluate whether surgical stripping of endometriomas in subfertile women improves the chance of a live birth. Secondary outcomes were impact on ovarian reserve and pain. MATERIAL AND METHODS: We conducted a systematic review and meta-analysis with results reported in accordance to the PRISMA guidelines...

Except for histological study, there are currently no suitable techniques available for the detection and identification of primordial follicles in ovary of primary ovarian insufficiency patients who have undetectable AMH levels. Also, the ability to locate and quantify follicles on ovarian cortex strips, without fixation, is valuable for patients who could undergo subsequent successful ovarian tissue transplantation. Although optical coherence tomography (OCT) is a well-established high resolution imaging technique without fixation commonly applied in biomedicine, few reports are available on ovarian tissue imaging...

The aim of the study was to investigate the effect of chlordane, heptachlor and mirex, on hormonal regulation of the force of myometrial contractions. Myometrial, endometrial, granulosa and luteal cells as well as strips of myometrium from non-pregnant cows were incubated with three insecticides at environmentally relevant doses (0.1, 1 or 10ng/ml). None of the insecticides affected the viability of studied cells. Chlordane stimulated, while heptachlor and mirex inhibited, secretion of testosterone and estradiol from granulosa cells as well as secretion of progesterone from luteal cells, respectively...

Cytoreductive surgery for patients with advanced epithelial ovarian cancer has been practised since the pioneering work of Tom Griffiths in 1975. Further research has demonstrated the prognostic significance of the extent of metastatic disease pre-operatively, and of complete cytoreduction post-operatively. Patients with advanced epithelial ovarian cancer should be referred to high volume cancer units, and managed by multidisciplinary teams. The role of thoracoscopy and resection of intrathoracic disease is presently investigational...

Acetyl tributyl citrate (ATBC), is a phthalate substitute used in food and medical plastics, cosmetics and toys. Although systemically safe up to 1000 mg kg(-1)  day(-1) , its ability to cause reproductive toxicity in females at levels below 50 mg kg(-1)  day(-1) has not been examined. This study evaluated the effects of lower ATBC exposures on female reproduction using mice. Adult CD-1 females (n = 7-8 per treatment) were dosed orally with tocopherol-stripped corn oil (vehicle), 5 or 10 mg kg(-1)  day(-1) ATBC daily for 15 days, and then bred with a proven breeder male...

OBJECTIVE: Electrically neutral argon plasma (PlasmaJet™) technology is a surgical option that helps to get an aggressive cytoreduction in selected patients with ovarian cancer because it can be directly applied by the surgeon to treat the tissue surface [1,2]. Upper abdominal surgical procedures are an important part of the surgery in these patients [3], there is a 22% complications rate when they are performed [4]. We present a surgical approach to ovarian cancer debulking using PlasmaJet™...
