Purpose Endometriosis of the umbilicus is rare, with the most common site being laparoscopy scars. We report here a case of spontaneously developed, solitary umbilical endometriosis, not associated with a surgical scar, that was successfull…

Endometriosis, a common, benign, estrogen-dependent disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue that is found primarily in the peritoneum, ovaries and rectovaginal septu…

Endometriosis, a disease affecting 3% to 10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue under the influence of estrogen. It is also becoming recognized as a condition in which ectopic endometr…

BACKGROUND: Accumulating evidence suggests that various epigenetic aberrations play definite roles in the pathogenesis of endometriosis. We investigated the histone acetylation status in endometriosis and the application of the histone deac…

CONTEXT: During the development of endometriotic lesions, excess fibrosis may lead to scarring and to the alterations of tissue function that are the characteristic features of this disease. Enhanced extracellular matrix contractility of en…

Chemokines, proteins that operate within the body's immune system, play numerous roles in menstruation, bacterial infection, implantation of embryos, and the maintenance of early pregnancy. They are also strongly related to the pathogenesis…

OBJECTIVE: Endometriosis is characterized by the ectopic growth of endometrial tissue. One of the first steps to the spread of endometriosis in the peritoneal cavity is the attachment of endometriotic cells to peritoneal surfaces after they…

Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue. Histologically, this disease is characterized by endometrial gland and stroma with surrounding dense fibrou…

The diagnosis of ureteral obstruction caused by endometriosis can be difficult. We present a 51-year-old multiparous Japanese women who had undergone right salpingo-oophorectomy at the age of 19 years. She underwent total hysterectomy, left…

CONTEXT: Decidualization of the endometrium involves the morphological and biochemical reprogramming of the estrogen-primed proliferative endometrial stromal compartment under the continuing influence of progesterone. OBJECTIVES: The aim o…

OBJECTIVE: To assess the use of heparin for the medical treatment of endometriosis-associated fibrosis. DESIGN: The effects of heparin on the endometriotic stromal cells (ECSCs)-mediated contractility were investigated. SETTING: Research …

Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue. Increasingly, endometriosis is also becoming recognized as a condition in which ectopic endometrial cells e…

Simvastatin significantly inhibited the proliferation of endometriotic stromal cells, attenuated the collagen gel contraction mediated by these cells, and suppressed endometriotic stromal cell attachment to collagen fibers. Simvastatin is c…

It is very rare that endometriotic lesions in the rectovaginal septum cause ileus. We report a case of bowel obstruction due to endometriotic lesions in the rectovaginal septum in a 22-year-old woman whose barium enema presented with apple-…

Tamoxifen is widely used for endocrine treatment and breast cancer prevention. It acts as both an estrogen antagonist in breast tissue and an estrogen agonist in the female lower genital tract. Tamoxifen causes severe gynecologic side effec…

BACKGROUND: Excessive fibrosis is frequently associated with endometriosis. To evaluate the involvement of the extracellular matrix contractility of endometriotic stromal cells (ECSCs) in the pathogenesis of endometriosis-associated fibrosi…

Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue. Increasingly, endometriosis is also becoming recognized as a condition in which ectopic endometrial cells e…

Most of the current medical treatments for endometriosis aim to downregulate estrogen activity. However, a high recurrence rate after medical treatment has been the most significant problem. BAY 11-7085, a soluble inhibitor of NK-kappaB act…

BACKGROUND: Most of the current medical treatments for endometriosis aim to down-regulate the estrogen activity. However, a high recurrence rate after medical treatments has been the most significant problem. Beta-hydroxyisovalerylshikonin …

OBJECTIVE: To evaluate the effect of hypoxia on the production of vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) in the human fallopian tube. DESIGN: The secretion of VEGF and sFlt-1 by cultured o…

OBJECTIVE: The aim of the current study is to evaluate the effect of insulin-like growth factor-I (IGF-I) on the production of vascular endothelial growth factor (VEGF) in the human fallopian tube. METHODS: Human oviductal epithelial cells…

The aim of the present study was to evaluate the effects of interleukin (IL)-1beta on the production of vascular endothelial growth factor (VEGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) in the human fallopian tube. Human oviductal e…

Most of the current medical treatments for endometriosis aim to down-regulate the estrogen activity. However, a high recurrence rate after medical treatments has been the most significant problem. Bufalin is a major digoxin-like immunoreact…

To evaluate the involvement of platelet-derived growth factor (PDGF) isoforms (PDGF-AlphaAlpha, PDGF-AB, and PDGF-BB) on endometrial tissue remodeling during the perimenstrual period, we investigated the effects of PDGF on the proliferation…
