Abstract Cellular development is tightly regulated as mature cells with aberrant functions may initiate pathogenic processes. The endometrium a highly regenerative tissue, shedding and regenerating each month. Endometrial stromal fibroblasts are regenerated cycle from mesenchymal stem play pivotal role in endometriosis, disease characterised by endometrial that grow outside the uterus. Why of some women more capable developing into endometriosis lesions not clear. Using isolated, purified...

Endometriosis is a gynaecological condition with an associated chronic inflammatory response. The ectopic growth of 'lesions', consisting endometrial cells outside the uterine cavity, stimulates response initiating activation macrophages, and resulting in increased cytokine factor concentrations peritoneal fluid (PF). Endometriosis‑associated inflammation long lasting. In patients endometriosis, risk developing ovarian cancer within 10 years, particularly endometrioid or clear cell subtype,...

Abstract Introduction Progestins are commonly prescribed first‐line drugs for endometriosis. High rates of non‐response and intolerance to these have been previously reported. However, no study date has investigated the characteristics comorbidities patients taking progestins in relation treatment outcomes, so identifying which will respond or tolerate is currently impossible. The purpose this study, therefore, was identify risk factors discontinuation Dienogest (DNG) women with Material...

Endocannabinoid (eCB) levels fluctuate in inflammatory conditions and as such may take part endometriosis-associated pain or even endometriosis pathogenesis. In this case-control (23 cases 19 controls) study, targeted lipids were measured the serum peritoneal fluid collected during laparoscopy. Endometriosis was confirmed histologically. Dysmenorrhea, abdominal pain, dyspareunia assessed using Numeric Rating Scale for pain. Steroids, eCBs, related quantified by liquid chromatography-tandem...
