Endometriosis is a chronic, hormone-dependent disease characterized by the presence of endometrial tissue in ectopic locations. Since treatment options for this are still limited, and cure rate unsatisfactory, search ways to treat symptoms modify course key importance improving quality life patients with endometriosis. So far, literature has shown that nutrition can influence endometriosis through hormonal modification altering inflammatory or oxidative response. subject scientific research,...

The most common manifestation of endometriosis, a condition characterized by the presence endometrial-like tissue outside uterus, is endometrioma, cystic ovarian lesion. It commonly occurring associated with chronic pelvic pain exacerbated prior to and during menstruation, as well infertility. exact pathomechanisms endometrioma are still not fully understood. Emerging evidence suggests pivotal role immune dysregulation in pathogenesis endometriomas, primarily influencing both local systemic...

Ultrasound-guided transvaginal ethanol sclerotherapy is one of the methods for ovarian endometrioma treatment. It involves aspiration cyst content and subsequent administration some fibrosis agent. This minimally invasive procedure does not reduce reserve hence, it addressed to patients with fertility plans. To date, there have been no reports this method being used in advanced disease stages. Therefore, we present a case patient deep infiltrating endometriosis who underwent treatment...

The cause of endometriosis remains unknown. However, studies investigating the link between this condition and immune system revealed several immunological abnormalities focused on cell-mediated immunity. As a major checkpoint, programmed cell death protein 1 (PD-1) displays an important inhibitory function in maintenance peripheral tolerance. expression PD-1 its ligand (PD-L1) may contribute to continuous T activation development inflammation injury tissue.

Endometriosis is a common disease, affecting up to 60-80% of women, with pelvic pain or/and infertility. Despite years studies, its pathogenesis still remains enigmatic. Genetic, hormonal, environmental, and lifestyle-related factors may be involved in pathogenesis. Thus, the design review was discuss possible role environmental development endometriosis. The results individual studies greatly differ, making it very difficult draw any definite conclusions. There no reasonable consistency...

Abstract The discordance between genome size and the complexity of eukaryotes can partly be attributed to differences in repeat density. Muller F element (∼5.2 Mb) is smallest chromosome Drosophila melanogaster, but it substantially larger (>18.7 D. ananassae. To identify major contributors expansion assess their impact, we improved sequence annotated genes a 1.4-Mb region ananassae element, 1.7-Mb from D for comparison. We find that transposons (particularly LTR LINE...

Immune system dysregulation is clinically evident in the pathogenesis of endometriosis (EMS). Changes dendritic cells (DCs) activity or phenotype may be involved implantation and growth endometrial tissue outside uterus disease. The TIM-3/Gal-9 axis implicated development immune tolerance. However, knowledge about exact role this pathway EMS extremely poor. In present study, we evaluated expression Gal-9 on myeloid DCs (mDCs) plasmacytoid (pDCs) peripheral blood (PB) peritoneal fluid (PF)...

Anti-Müllerian hormone (AMH) is a glycoprotein produced by the granulosa cells of preantral and small antral follicles. AMH concentrations reflect ovarian physiology with high precision, thus serving as more sensitive marker reserve than chronological age. This plays role in pathogenesis menstrual disorders fertility obesity polycystic ovary syndrome. The evaluation may also be useful diagnosis or monitoring therapy tumors.
