Controlled ovarian hyperstimulation (COH) affects adversely implantation following in vitro fertilization and embryo transfer. COH with gonadotropins alters endometrial receptivity and luteal function. In addition periovulatory endometrial characteristics in stimulated cycles are considerably different compared with the natural cycles, and periovulatory secretory transformation is consistently ...
Multi-drug resistance protein 4 (MRP4), a potential chemotherapeutic target as well as a transporter for endogenous signaling molecules (e.g. prostaglandins), is known to be expressed in the endometrium, although its possible role(s) in the physiology of the endometrium remains unknown. Here, we show that MRP4 is upregulated at implantation window and localized to the basolateral membrane of th...
BACKGROUND Understanding the molecular basis of embryonic implantation is of great clinical and biological relevance. Little is currently known about the adhesion receptors that determine endometrial receptivity for embryonic implantation in humans. METHODS AND PRINCIPAL FINDINGS Using two human endometrial cell lines characterized by low and high receptivity, we identified the membrane recep...
BACKGROUND Surgery for major malformations of the outer and middle ear involves aesthetic as well as functional aspects. Whereas reconstruction of the auricle with autogenous rib cartilage is well established and has shown favorable results, functional repair using classic reconstructive techniques is possible only in a limited group of patients and the outcome is often unsatisfactory. Active m...
The window of implantation is defined by the inhibition of uterine epithelial proliferation, structural epithelial cell remodeling, and attenuated estrogen (E2) response. These changes occur via paracrine signaling between the uterine epithelium and stroma. Because implantation defects are a major cause of infertility in women, identifying these signaling pathways will improve infertility inter...
Nineteen adults and 9 children who received a unilateral cochlear implant between 2002 and 2007 were included in the study. All subjects were preoperatively diagnosed with significant residual hearing in low frequencies, termed as 'partial deafness', and were implanted according to a 6-step round window surgical technique for partial deafness cochlear implantation. Hearing was preserved to a gr...
