BACKGROUND Time-lapse observation presents an opportunity for optimizing embryo selection based on morphological grading as well as providing novel kinetic parameters, which may further improve accurate selection of viable embryos. The objective of this retrospective study was to identify the morphokinetic parameters specific to embryos that were capable of implanting. In order to compare a lar...

background: women with polycystic ovary syndrome have lower pregnancy rates, possibly due to the decreased uterine  receptivity.successful implantation depends on protein networks that are essential for cross-talk between the embryo and endometrium.apolipoprotein a1 has been proposed as a putative anti-implantation factor. in this study, we evaluated apolipoprotein a1 expression in human endome...

Background: Implantation of vascular access devices is of great importance in critically ill patients or those vulnerable to clinical worsening. The aim of this study was to identify the complications of implantation of vascular access leading to complaints from patients, in the forensic medicine commissions of Tehran. Methods: The present descriptive-cross sectional study was performed on all...

Sutureless aortic bioprosthesis implantation is an alternative technique in high-risk patients undergoing aortic valve replacement with a possible reduction in the extracorporeal circuit time and reliable haemodynamic features. A 3F Enable (ATS Medical-Medtronic, Inc., Minneapolis, MN, USA) has shown very good results. We report the first upward displacement of 3F Enable three months post impla...

OBJECTIVES Early cochlear implantation has been widely promoted for children who derive inadequate benefit from conventional acoustic amplification. Universal newborn hearing screening has led to earlier identification and intervention, including cochlear implantation in much of the world. The purpose of this study was to examine age and time to cochlear implantation and to understand the facto...

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...

Background: Implantation is characterized by the interaction of two immunologically and genetically distinct tissues. The embryo differs from the cells of the mother, and would be rejected as a parasite by the immune system of the mother if it didn’t secrete immunosuppressive agents. Thus, immunological rejection of the fetus due to recognition of paternal antigens by the maternal immune system...

Background: Implantation is a crucial period determining the success of a full pregnancy. Endocrine disruptors such as phytoestrogens (PEs) were thought to adversely influence embryonic implantations. However, the mechanism by which they upset implantation was not fully elucidated. Aims: The effect of administering soy isoflavones on the implantation of Wistar ...
