Research questionHow significant is the impact of dysmenorrhea on work productivity and quality of life (QoL) among Japanese women?.MethodsThis large-scale cross-sectional study was conducted using a web-based self-report questionnaire admi…
Endometriosis is a serious disorder that can lead to infertility. The immune system, particularly regulatory T cells (Tregs), is involved in endometriosis and infertility; however, endometriosis-associated infertility is poorly understood. …
Menstrual blood, containing high iron levels, can undergo retrograde transport into the abdominal cavity. Excess iron causes oxidative stress and inflammation. Iron metabolism is regulated by hepcidin, and serum hepcidin levels are increase…
Although nutrient status plays an important role in cell metabolism, its significance in endometriosis is obscure. Herein, we investigated the effects of a low-nutrient microenvironment on endometriosis. Stromal cells (SCs) from ovarian end…
PROBLEM: Inflammation and immune responses play crucial roles in the development of endometriosis. Although interleukin-9 (IL-9) has a pro-inflammatory function in chronic inflammatory diseases, its function in endometriosis remains unknown…
PURPOSE: We aimed to investigate the clinical and magnetic resonance imaging (MRI) characteristics of uterine adenomyosis, in which there is an extensive area of high signal intensity in the myometrium on T2-weighted MRI. METHODS: This retr…
STUDY QUESTION: Is a peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α)-mediated pathway involved in the development of endometriosis? SUMMARY ANSWER: PGC-1α plays critical roles in inflammation and cell proliferation of e…
Context: Endometriosis is a chronic inflammatory disease associated with altered immune response to endometrial cells facilitating the implantation and proliferation of ectopic endometrial tissues. Although regulatory T (Treg) cells play a …
AIM: The aim of this study was to investigate the prevalence of hypointensity on T2 star-weighted imaging (T2*WI), which is useful for detecting hemosiderin, in endometriomas and other ovarian tumors. The efficacy of detecting adhesions aro…
