Di-(2-ethylhexyl) Phthalate Triggers Proliferation, Migration, Stemness, and Epithelial-Mesenchymal Transition in Human Endometrial and Endometriotic Epithelial Cells via the Transforming Growth Factor-β/Smad Signaling Pathway.

Di-(2-ethylhexyl) phthalate (DEHP) is a frequently used plasticizer that may be linked to the development of endometriosis, a common gynecological disorder with a profound impact on quality of life. Despite its prevalence, vital access to treatment has often been hampered by a lack of understanding of its pathogenesis as well as reliable disease models. Recently, epithelial-mesenchymal transition (EMT) has been suggested to have a significant role in endometriosis pathophysiology.

Assessment of the effects of prostaglandins on myometrial and leiomyoma cells in vitro through microRNA profiling.

It is well known that prostaglandin (PG) E2 and PGF2α are secreted in copious amounts from the menstruating uterus. The aim of the present study was to determine whether PGs affect the growth of uterine leiomyomas (ULs) to the same extent as estrogen or progesterone (P4). The present study evaluated the expression of eight microRNAs (miRNAs) by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) through treatment with estradiol (E2), P4, PGE2, PGF2α and each antagonist or cyclooxygenase‑2 (COX‑2) inhibitor of cultured leiomyoma and myometrial cells (LC and MC, respectively).

A Rare Case of an Autoamputated Ovary with Mature Cystic Teratoma.

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.

Lymphoepithelioma-like carcinoma of the uterine cervix.

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is exceedingly uncommon. We herein report a rare case of cervical LELC. A 45-year-old woman was admitted to gynecology department with vaginal bleeding for one month.

Non-puerperal Uterine Inversion Presented with Hypovolemic Shock.

We report a non-puerperal uterine inversion with nulliparous women caused by huge pedunculated submucosal fibroid. Massive bleeding from protruding mass through vagina brought the heart to stop in 42-year-old nulliparous woman. She became cardiopulmonary resuscitation survivor in emergency room and then underwent laparotomy which ended in successful myomectomy rather than hysterectomy considering her demand for future fertility.

The effectiveness of laparoendoscopic single-site surgery (LESS) compared with conventional laparoscopic surgery for ectopic pregnancy with hemoperitoneum.

Objective: The purpose of this study was to compare clinical outcomes of conventional laparoscopic surgery and laparoendoscopic single-site surgery (LESS) in the surgical treatment of tubal ectopic pregnancy.

Material And Methods: A total of 156 patients were diagnosed with ectopic pregnancies by ultrasonography and serum β-human chorionic gonadotrophin (β-hCG) levels at Pusan National University Yangsan Hospital from January 2009 through December 2013. We excluded 28 patients who only received medical treatment, 15 patients who underwent surgery by laparotomy for severe hypovolemic shock, and 30 patients who presented with less than 1 L of hemoperitoneum.

Selective Interference Targeting of Lnk in Umbilical Cord-Derived Late Endothelial Progenitor Cells Improves Vascular Repair, Following Hind Limb Ischemic Injury, via Regulation of JAK2/STAT3 Signaling.

The Lnk adaptor protein is a strong negative regulator that affects self-renewal of hematopoietic stem cells and vascular repair in injured tissues. However, the signaling mechanisms through which these proteins influence the vascular regeneration function of endothelial progenitor cells (EPCs) remain unknown. In this study, we investigated the effect of Lnk-targeted small interfering RNA (si-lnk) on the clonogenic proliferative potential and vascular regenerative function of EPCs and the activation of the JAK/STAT3 signaling pathway.

Sildenafil Inhibits Advanced Glycation End Products-induced sFlt-1 Release Through Upregulation of Heme Oxygenase-1.

Objectives: We examined the effect of sildenafil citrate on advanced glycation end products (AGEs)-induced soluble fms-like tyrosine kinase 1 (sFlt-1) release in JEG-3 choriocarcinoma cells.

Methods: Cells were incubated with control bovine serum albumin (BSA) or AGEs-BSA, and expression of sFlt-1 mRNA and protein release was determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. AGEs-BSA increased sFlt-1 mRNA expression and protein release in a dose-dependent manner.

Neovascularization in a mouse model via stem cells derived from human fetal amniotic membranes.

In this study, we evaluated the effect of culture-expanded mesenchymal stem cells (MSCs), derived from amniotic membranes, on neovascularization and blood flow, in an animal model of limb ischemia in immune-deficient mice. MSCs were cultured from human amniotic membranes by collagenase digestion. Human amniotic mesenchymal stem cells (hAMSCs) were administered intramuscularly at three different sites of the ischemic leg whose femoral vessels were ligated.

A case of Cushing s syndrome in pregnancy secondary to an adrenal cortical adenoma.

Cushing s syndrome in pregnant women is rare and difficult to be diagnosed because of the syndrome's association with oligomenorrhea or amenorrhea and the changes in cortisol metabolism during normal pregnancy. Cushing syndrome in pregnancy is usually confused with complicated pregnancy, such as preeclampsia or gestational diabetes, and its rarity leads to a low degree of clinical suspicion, often delaying diagnosis. We experienced a case of Cushing s syndrome in pregnancy, which had been considered as the severe preeclampsia and gestational diabetes due to uncontrolled hypertension and hyperglycemia.
