Filter by:uterine NK (uNK) cells are characterized by a high expression of CD56 (CD56brihgt), lack of CD16 expression, high secretion of cytokines and rather low cytotoxic activity. It has been shown that uNK cells increase in number during the late secretory phase and during early pregnancy. This study was designed to assess the possible role of uNK cells in repeated ICSI failure.
This is a prospective, clinical, monocentric study aimed to collect biological samples and study microbiota from subjects suffering from subjects with recurrent cervicovaginitis, subjects with endometriosis, subjects with repeated implantation failures and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological). The study will allow to: - Provide biological samples (faeces, saliva, vaginal, urine) from healthy volunteers and patients suffering from selected disease to the first Italian microbiota biobank; - Study microorganisms using different in vitro and in vivo techniques; - Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
The randomized, placebo-controlled multicenter trial is conducted in five centers in China. After screening and obtaining the signed informed consent , the participants are randomly divided into two groups: acupuncture +IVF group and sham acupuncture +IVF group.
In order to further explore the clinical utility of endometrial receptivity array in patients with repeated implantation failure, the patients divide into the experimental group or the control group. In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. Statistical analysis of the two groups of primary endpoint and secondary endpoint are done.
Despite recent advances in clinical and laboratory techniques of Assisted Reproductive Technology (ART), the pregnancy rate remains around 30% per cycle. It has been estimated that 50% to 75% of lost pregnancies are due to failure of implantation. The process of implantation is a locally controlled paracrine/juxtacrine-mediated phenomenon. Successful implantation depends on the synchronized "cross-talk" between a functional blastocyst and a "receptive" endometrium. This process leads to apposition, attachment and invasion of embryos and subsequent normal placentation. So the objective of this study is investigate the impact of intrauterine injection of human chorionic gonadotropin (hCG) at the day of ovum pick-up on implantation and pregnancy rates in patients with recurrent implantation failure.
Characterization of the uterine microbiome in women with repeated implantation failure as well as in normal fertile women.
The purpose of this study is to find out the possible relationship among TWEAK/Fn14, JAK/STAT3 and IDO as well as their roles in the dysfunction of immune micro-environment of endometrium in people diagnosed as repeated implantation failure after in vitro Fertilization-embryo transfer(IVF-ET). We will use the technology of Western-blot and Immunohistochemistry to find out the relationship of the expression of TWEAK/Fn14, JAK/STAT3 and IDO in endometrium . Also, we will use technology of Western-blot and Immunohistochemistry to determine whether there are differences of the the expression of TWEAK/Fn14, JAK/STAT3 and IDO in endometrium between RIF group and control group.
This study intends to carry out a prospective, randomized, double blind and controlled study to compare the influence of Atosiban and placebo on uterine contraction frequency, endometrial blood flow perfusion, oxytocin and serum concentration of PGF2α, embryo implantation rate and clinical pregnancy rate on the RIF population after fresh embryo transfer, so as to further clarify the curative effect of Atosiban in the treatment of RIF and provide evidence-based basis for Atosiban for application in RIF population.
Pipelle was found to increase pregnancy and implantation rates in women undergoing IVF treatment in general, and in particular in repeated implantation failure (RIF). However, there is virtually no data regarding the optimal timing for the pipelle. The current study aims to compare between follicular and luteal pipelle on pregnancy rate in RIF patients.
Atosiban, administered at embryo transfer, can improve the implantation rate and the clinical pregnancy rate in patients with repeated implantation failure undergoing IVF-ET (in-vitro fertilization and embryo transfer).
