Research question: Do miRNAs play a role in regulating endoplasmic Reticulum Stress (RS) and Unfolded Protein Response (UPR) decidualized cells endometrium associated with reproductive failures?Design: Endometrial stromal cell line St-T1b was vitro 8-Br-cAMP during 5 days, or treated the RS-inducer Thapsigargin (Tg). Expression of RS-sensors, UPR markers potential miRNA regulators were analysed...

background: the value of serial measurement of serum ß subunit of human chorionic gonadotropin (ßhcg) and ultrasonography in the early diagnosis of ectopic pregnancy has well established. objective: the objective of this study was to explore the diagnostic value of raising level of serum ßhcg, single measurement of progesterone (p) and estradiol (e2) in early diagnosis of ectopic pregnancy. mat...

background: ovarian pregnancy is a rare form of the non-tubal ectopic pregnancy. it ends with rupture before the end of the first trimester. one of the important risk factors for ovarian pregnancy is in the use of intra uterine devices (iud). case:  we report here one such uncommon case of ovarian ectopic pregnancy. our patient is a 30 years old multiparous woman with two previous cesarean sect...

In the mouse, the attachment reaction between the blastocyst trophectoderm and the receptive uterine luminal epithelium occurs at 2200-2300 h on day 4 of pregnancy and is rapidly followed by transformation of stromal cells into decidual cells (decidual cell reaction). This process can also be induced experimentally (deciduoma) by intraluminal oil infusion in the uterus on day 4 of pseudopregnan...

BACKGROUND In the rat, the maintenance of gestation is dependent on progesterone production from the corpora lutea (CL), which are under the control of pituitary, decidual and placental hormones. The luteal metabolism of progesterone during gestation has been amply studied. However, the regulation of progesterone synthesis and degradation during pseudopregnancy (PSP), in which the CL are mainly...

background: bilateral ectopic pregnancy is a rare condition and is divided in two subgroups, primary and secondary, based on history of assisted reproductive technology. case presentation: a 30 year old primigravid woman with history of infertility and ovulation induction presented to a hospital in kashan in year 2013. she had vaginal bleeding, abdominal pain and ultrasound findings suggested e...
