BACKGROUND The aim of this study was to evaluate the effect of trichostatin A (TSA) in a mouse model of endometriosis on serum tumour necrosis factor alpha (TNFalpha) levels, hotplate latency, lesion size and immunoreactivity to Trpv1, Pkcepsilon and Pgp9.5. METHODS We used 30 adult female mice, and endometriosis was induced by auto-transplanting pieces of uterus (ENDO) or fat (SHAM) to perit...

The plant Asparagus racemosus is used traditionally in Kenya for a variety of medicinal purposes including the management pain, asthma, and premature labour. However, dearth empirical studies means that there limited information on acute toxicity pharmacological effects to support these uses by local plant. aim this study was, therefore, evaluate toxicity, analgesic, smooth muscle relaxation aq...

Background: To achieve multiple oocytes for in vitro fertilization, ovulation induction is induced by gonadotropins however, it has several effects on oocytes and embryo quality and endometrium receptivity. The aim of this study was to assess ultrastructural changes of corpus luteum after ovarian induction using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (HCG) during l...

Endometriosis, a pathological condition in which the endometrium grows outside the uterus, is one of the most common causes of female infertility; it is diagnosed in 25-40% of infertile women. The mechanism by which endometriosis affects the fertility of females remains largely unknown. We examined the ultrastructure of oocytes from patients with minimal or mild endometriosis and control female...

Embryonic implantation comprises a dynamic and complicated series of events, which takes place only when the maternal uterine endometrium is in a receptive state. Blastocysts reaching the uterus communicate with the uterine endometrium to implant within a narrow time window. Interplay among various signalling molecules and transcription factors under the control of ovarian hormones is necessary...

Dysfunctional uterine bleeding is defined as pathological bleeding from uterus unexplained on basis of inflammation, neoplasia or pregnancy within the uterus. The present study was undertaken with the aim of studying the different histological patterns of endometrium in patients of DUB. This study includes 84 patients with clinically diagnosed DUB who had undergone either hysterectomy or D&C. S...

In mammals, embryo implantation is an essential step in reproduction. Implantation is a phenomenon that involves crosstalk between the blastocyst and the maternal endometrium. However, the molecular basis of the connections between the blastocyst and endometrium is not yet fully understood. Amphiregulin is a member of the epidermal growth factor family and is known to be expressed in the lumina...

Interferon-stimulated gene 15 (ISG15) is a ubiquitin homolog expressed in uteri of ruminants in response to interferon (IFN)-tau and is also induced during pregnancy in the uteri of mice, pigs, humans, and baboons. This study examined expression of ISG15 and its conjugation to target proteins in the ovine uterus beyond the period of IFNtau secretion by the conceptus. Although steady-state level...

Pregnant BALB/c mice were inoculated intravaginally on day 5 of gestation with the Chlamydia trachomatis mouse pneumonitis biovar. Animals that received 10(5), 10(6), or 10(7) inclusion-forming units (IFU) of C. trachomatis delivered prematurely on days 15 to 16 of gestation. A focal inflammatory infiltrate was observed in the wall of the uterus on the day 14 of gestation in animals inoculated ...

Müllerian and vaginal anomalies are congenital malformations of the female reproductive tract resulting from alterations in the normal developmental pathway of the uterus, cervix, fallopian tubes, and vagina. The most common of the Müllerian anomalies affect the uterus and may adversely impact reproductive outcomes highlighting the importance of gaining understanding of the genetic mechanisms t...
