Received: 2/Mar/2008 The success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (ART) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (IVFET). The techniques used in ART have advanced considerably since the ...

BACKGROUND Cochlear implantation has become a mainstream treatment option for patients with severe to profound sensorineural hearing loss. During cochlear implant, there are key surgical steps which are influenced by anatomical variations between each patient. The aim of this study is to determine if there are potential predictors of difficulties that may be encountered during the cortical mast...

The aim of this study was to investigate the effect of surgical intervention on the expression of leukemia inhibitory factor (LIF) and L-selectin ligand in the endometrium of patients with hydrosalpinx during the implantation window. A total of 60 patients with hydrosalpinx and 30 patients with tubal obstruction were recruited, and immunohistochemistry was performed to detect the expression of ...

In fertile women, HOXA-10 and HOXA-11 expression rises during the luteal phase, with the peak occurring during the implantation window, and stays at a high level until the end of the cycle. We evaluated the transcript and protein levels of HOXA-10 and HOXA-11 in the endometria of patients with idiopathic infertility (n = 15) and control patients (n = 10). The amounts of mRNA were determined by ...

BACKGROUND At present, a diagnostic tool with high specificity for impaired endometrial receptivity, which may lead to implantation failure, remains to be developed. We aimed to assess the different endometrial microRNA (miRNA) signatures for impaired endometrial receptivity by microarray analysis. METHODS A total of 12 repeated implantation failure (RIF) patients and 10 infertile patients, w...

We investigated the effects of a modified Shoutaiwai recipe on integrin β3 and leukemia-inhibitory factor (LIF) in the endometrium of controlled ovarian hyperstimulation (COH) mice during the implantation window. Seventy non-pregnant mice were randomly divided into 3 groups: a traditional medicine (TCM) treatment group (N = 30), an aspirin treatment (N = 30) group, and a control group (N = 10)....

OBJECTIVES/HYPOTHESIS The purpose of the study was to investigate whether cochlear implantation using the round window approach provided better preservation of residual hearing than the cochleostomy approach. STUDY DESIGN Case-control study. METHODS We designed a case-control study including 40 patients from a tertiary referral center who underwent cochlear implantation surgeries using devi...

Background: In fertile women, glycodelin and glutathione peroxidase 3 (GPx3) genes expression rises during the luteal phase, with a peak occurring during the implantation window. The expression of these genes decreases in women with myomas. To determine whether myomectomy would reverse glycodelin and GPx3 expression, we evaluated the transcript levels of these genes in the endometrium of patien...

OBJECTIVE The aim of this study was to compare the endometrial expression of milk fat globule-EGF factor 8 (MFG-E8), its receptor integrin αvβ3, and leukemia inhibitory factor (LIF) in patients with endometriosis and infertility and in healthy fertile patients during the window of implantation. METHODS Five patients with peritoneal endometriosis and infertility (case group) and four healthy f...
