background: punica granatum linn. (pg) is native to the mediterranean region. its flower exhibited antioxidant activity. the present study attempt to investigate the effect of these extract on uterine contraction and its possible mechanism(s). methods: thirty five female wistar rats (200-300 g) at estrous phases of cycle was examined in this study; pieces of virgin adult rat uterus (1.5 cm) wer...

It was assumed that uterine stem cells are responsible for the unique regenerative capacity of uterine. Therefore, the aim of the present study was to investigate the expression of the pluripotent stem cell markers in the mice uterine tissue during different stages of estrous cycles. Twelve virgin female NMRI mice (6 to 8 weeks old) were considered at proestrus, estrus, metestrus and diestrus a...

17Beta-estradiol (E2) acts through the estrogen receptor (ER) to regulate uterine epithelial cell growth, proliferation, differentiation, and secretory protein production. We have previously shown that E2-induced uterine epithelial proliferation is mediated indirectly by ER alpha-positive stroma; epithelial ER alpha is neither necessary nor sufficient for E2-induced uterine epithelial mitogenes...

The objective was to verify the hypothesis of a 'first uterine pass effect' or direct preferential vagina-to-uterus transport, suggested by the evidence of higher than expected uterine tissue concentrations after vaginal administration of progesterone; we used a human ex-vivo uterine perfusion model. A mixture of tritiated (3H) and unlabelled progesterone was applied to the cuff of vaginal tiss...

objective: : polycystic ovary syndrome (pcos) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. in this study, the effect of pcos induction was studied using estradiol valerate. materials and methods: ad...

The uterus is the reproductive organ where embryo formed by fertilization of sperm and egg settles continues its development until birth. With transition transplantation from experimental studies to clinical trials starting have babies in this way, offers a solution that can enable these women children genetically on their own grow them wombs. Uterine transplant procedure combines both assisted...

Infertility caused by ovarian or tubal problems can be treated using In Vitro Fertilization and Embryo Transfer (IVF-ET); however, this is not possible for women with uterine loss and malformations that require uterine reconstruction for the treatment of their infertility. In this study, we are the first to report the usefulness of decellularized matrices as a scaffold for uterine reconstructio...

Leiomyosarcoma (LMS) is one of the most common subtypes of soft tissue sarcoma in adults and can occur in almost any part of the body. Uterine leiomyosarcoma is the most common subtype of uterine sarcoma. Increased awareness of this unique histology has allowed for the development of drugs that are specific to LMS and has begun to shed light on the similarities and possible unique aspects of so...
