BackgroundPatients with chronic pancreatitis (CP) often have severe and intractable abdominal pain, leading to decreased quality of life (QOL), inability to work or attend school, and increased health care costs due to repeated emergency ro…

BACKGROUND: MicroRNAs (miRNAs) have been implicated to play a vital role in development, differentiation, cell proliferation and apoptosis. However, which miRNAs are actually associated with endometriosis-associated ovarian cancer remains c…

INTRODUCTION: The aim of this study was to investigate the effect of laparoscopic endometriotic cystectomy and vaporization on ovarian reserve. METHODS: We prospectively analyzed the serum level of anti-Mullerian hormone (AMH) in 62 patient…

Aim: To investigate which risk factors contribute to a lower oocyte retrieval ratio in women who are receiving controlled ovarian hyperstimulation. Methods: The authors retrospectively analyzed 329 in vitro fertilization (IVF) cycles under …

It remains unclear whether serum antibody titer against Porphyromonas gingivalis (Pg) and inflammatory components lead to periodontal deterioration in each gender, as periodontal and systemic status is influenced by gender. The present stud…

Until recently, ovarian clear cell carcinoma was recognized by its unique morphology and unfavorable patient outcome primarily due to tumor chemoresistance. Recently, specific molecular characteristics of ovarian clear cell carcinoma, such …

Purpose: To investigate the effect of moderate to severe endometriosis on mRNA expression of growth differentiation factor-9 (GDF-9) in the granulosa cells of mature follicles. Methods: Follicular fluid (FF) was obtained from 13 patients wi…

PURPOSE: We performed TaqMan genotyping assays of anti-Mullerian hormone (AMH) and anti-Mullerian hormone receptor type II (AMHRII) single nucleotide polymorphisms (SNPs) in order to investigate how their frequency and distribution affect i…

Study objectiveTo evaluate how endometriotic cystectomy and vaporization affect ovarian reserve after conservative surgery.DesignProspective study (Canadian Task Force classification II-1).SettingHokusetsu General Hospital.PatientsNinety-ni…

Dienogest, a synthetic progestin, has been shown to be effective against endometriosis, although it is still unclear as to how it affects the ectopic endometrial cells. Decorin has been shown to be a powerful endogenous tumor repressor acti…

PurposeExamination of the mitochondrial mRNA expression in granulosa cells from an unspecified population of infertile patients to evaluate whether recombinant follicle stimulating hormone (recFSH) is more effective in producing higher qual…

Clear cell adenocarcinoma of the ovary (OCC) is a chemo-resistant tumor with a relatively poor prognosis and is frequently associated with endometriosis. Although it is assumed that oxidative stress plays some role in the malignant transfor…

Mucocele of the appendix due to endometriosis is extremely rare, and there are only 10 previously reported cases in the English literature. We report a case of mucocele of the appendix due to endometriosis and provide the first review of th…

INTRODUCTION: GPR30 is a seven-transmembrane G protein-coupled estrogen receptor that regulates endometrial cellular responses to estrogen. GPR30 is often highly expressed in cancer cells from aggressive tumors. The aim of this study was to…

BACKGROUND: The resistance of endometriotic tissue to progesterone can be explained by alterations in the distribution of progesterone receptor (PR) and estrogen receptor (ER) isoforms. The aims of this study were to examine the expressions…

UnlabelledObjectivesG protein-coupled receptor 30 (GPR30) is a 7-transmembrane estrogen receptor that functions alongside traditional estrogen receptors to regulate the cellular responses to estrogen. Recent studies suggest that GPR30 expre…

ObjectiveTo understand the role of ectopic endometriotic stromal cells in ovarian endometriosis (OEM) and the associated risks for infertility and carcinogenesis.DesignAnalyses of secreted proteins and gene expression using immortalized eut…

OBJECTIVE: To evaluate how endometriosis affects the expression of estrogen and progesterone receptors mRNA in granulosa cells. DESIGN: Prospective study. SETTING: IVF-ET program at Osaka Medical College. PATIENT(S): Eighteen patients wi…

The expression of mitochondrial genes in granulosa cells was quantitated by real-time polymerase chain reaction. The expression ratio of mitochondrial genes in granulosa cells of patients with severe endometriosis showed no statistically si…

BackgroundAlthough intraductal papillary mucinous neoplasm (IPMN) of the pancreas is acceptable as a distinct disease entity, the concept of mucin-secreting biliary tumors has not been fully established.Case presentationWe describe herein a…

ObjectiveTo evaluate survivin gene expression in granulosa cells from infertile patients and examine the relationship between survivin gene expression and infertile clinical background.DesignProspective study.SettingIVF-ET program at Osaka …

Survivin is a novel inhibitor of apoptosis (IAP), and the two splice variants of survivin (survivin-2B and survivin-EX3) have been identified. Gene expression levels of survivin, survivin-2B and survivin-EX3 in 56 ectopic (16 peritoneal red…

OBJECTIVE: The aim of our study was to compare T2-weighted and contrast-enhanced dynamic T1-weighted images with histologic findings in assessing the depth of myometrial invasion by endometrial carcinoma in adenomyosis. MATERIALS AND METHOD…

Angiogenesis is essential for the pathogenesis of endometriosis. Gene expression levels of vascular endothelial growth factor (VEGF) A and C in 10 eutopic endometrial, 23 normal peritoneal, and 62 endometriotic tissues surgically obtained f…

Various types of cell adhesion molecules and matrix metalloproteinases (MMPs) seem to play an important role in the invasion process of endometriosis; however, limited investigation has focused on their gene expression in human peritoneal e…
