BACKGROUND: Despite the good prognosis in patients with transplant organs, limited evidence is available on how immunosuppressants affect pregnancy. The aim of this study was to determine whether immunosuppressant use affects the pregnancy …

PROBLEM: Recently, interleukin (IL)-32 has been suggested to be involved in the pathogenesis of endometriosis. The aim of this study was to investigate whether serum IL-32 level might be used as a biomarker for diagnosis of endometriosis. …

Uterine leiomyoma is found in ~50-80% of women of a reproductive age and is the most common reason for hysterectomy. Recently, posttranscriptional gene silencing by microRNAs (miRs) has been reported as a mechanism for regulating gene expre…

OBJECTIVE: This study was aimed at identifying a correlation between polycystic ovarian morphology (PCOM) and the severity of primary dysmenorrhea in young Korean women. METHODS: A total of 592 patients who visited a tertiary hospital from…

Aquaporins (AQPs) are involved in cell migration, proliferation and carcinogenesis in tumor development and physiologic inflammatory processes, but their associations with endometriosis have not been fully evaluated. In this study, tissue s…

Estrogen affects endometrial cellular proliferation by regulating the expression of the c-myc gene. B-cell translocation gene 1 (BTG1), a translocation partner of the c-myc, is a tumor suppressor gene that promotes apoptosis and negatively …

Background: Repair of DNA double strand break (DSB) is an important mechanism for maintaining genetic stability during a DNA damage event. Although, a growing body of recent evidence suggests that DNA DSBs and related repair mechanisms may …

Among the several components in Korean red ginseng, the saponin components are known to have various pharmacologic activities. The objective of this study was to evaluate therapeutic effects of saponin extracts from Korean red ginseng on en…

AIMS: Our objective was to predict natural pregnancy after endometriosis surgery using the endometriosis fertility index (EFI). METHODS: A retrospective medical records review was conducted, examining patients surgically treated for endome…

This research aimed to evaluate the potential therapeutic effects of Rg3 on endometriosis and identify target miRNAs. We designed an in vitro study using human endometrial stromal cells (HESCs) obtained from patients with endometriosis and …

OBJECTIVE: This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS: We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 20…

OBJECTIVE: The aim of this study was to evaluate the effectiveness of postoperative levonorgestrel-releasing intrauterine system (LNG-IUS) insertion after gonadotropin-releasing hormone agonist (GnRH-a) treatment for preventing endometrioti…

To investigate the effects of trichostatin A (TSA) on nonsteroidal anti-inflammatory drug-activated gene 1 (NAG-1) expression and apoptosis in human endometriotic stromal cells (HESCs), ectopic endometrial tissues were obtained from 15 pati…

PURPOSE: This study aimed to investigate whether Müllerian inhibiting substance (MIS) in combination with calcitriol modulates proliferation and apoptosis of human ovarian cancer (OCa) cell lines (SKOV3, OVCAR3, and OVCA433) and identify th…

Expression and possible role of non-steroidal anti-inflammatory drug-activated gene-1 (NAG-1) in the human endometrium and endometriosis

background: Recently, proteomic technologies have demonstrated that several proteins are differently expressed in various body fluids of patients with endometriosis compared with those without this condition. The aim of this study was to in…

Oxidative stress has been proposed as a potential factor associated with the establishment and progression of endometriosis. Although a few studies have shown possible mechanisms which may play roles in development, progression of endometri…

The objective of this study was to evaluate whether robotic tubal reanastomosis after segmental resection of tubal pregnancy is a feasible means of preserving tubal integrity and natural fertility in those with compromised contralateral tub…

Although the pathophysiology of adenomyosis has not been clarified, it is thought to be related to ectopic endometrium, which depends on hormonal regulation. The levonorgestrel-releasing intrauterine system (LNG-IUS) is effective for the me…
