background: acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. muc1 an integral membrane mucin is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. objective: the aim of this study was to evaluate the changes in muc1 expression of gravid mouse endometrium with and without hyperstimulation ...
PROBLEM The advantages of bilateral, simultaneous cochlear implantation include: the possibility to pre-empt cochlear calcification following meningitis; reduction of the intervention to only one procedure, general anaesthetic and course of clinical care (with obvious benefits for the patient); and greater cost-effectiveness. The disadvantages of such a procedure include: doubling the risk of a...
Valvular disease is common in patients undergoing left ventricular assist device (LVAD) implantation. Concomitant valve surgery increases procedural complexity and cardiopulmonary bypass time and may lead to worse outcomes. Although mitral regurgitation is the most common mitral valve dysfunction in patients undergoing LVAD implantation, mitral stenosis (MS) is occasionally encountered. MS can ...
RATIONALE Percutaneous aortic valve procedures are a major breakthrough in the management of patients with aortic stenosis. Residual gradient and residual aortic regurgitation are major predictors of midterm and long-term outcome after percutaneous aortic valve procedures. We hypothesized that (1) induction/recovery of high molecular weight (HMW) multimers of von Willebrand factor defect could ...
Method From 1989 to 2013, 44 patients (15 neonates) underwent pacemaker implantation within the first year of life. The mean age and weight were 101.2 ± 97.2 days and 4.8 ± 1.8kg at the time of pacemaker implantation. The Indication for pacemaker implantation were postoperative atrioventricular block in 23, congenital atrioventricular block in 16, sinus node dysfunction in 4, and myocarditis in...
Background and aim: Permanent cardiac pacing is the most efficient treatment for patients with symptomatic bradycardia and high-degree atrioventricular (AV) block. For effective pacing, sensing and pacemaker battery longevity; ventricular pacing threshold (VPT) levels, lead impedance levels and Rwave amplitude levels must be desirable. We aimed to search the association between elevated serum t...
AIM To investigate the impact of timing of same-admission orthotopic heart transplant (OHT) after left ventricular assist device (LVAD) implantation on in-hospital mortality and post-transplant length of stay. METHODS Using data from the Nationwide Inpatient Sample from 1998 to 2011, we identified patients 18 years of age or older who underwent implantation of a LVAD and for whom the procedur...
BACKGROUND Cochlear implants (CIs) can improve speech recognition for children with severe congenital hearing loss, and open-set word recognition is an important efficacy measure. This study examined Mandarin open-set word recognition development among Chinese children with CIs and normal hearing (NH). METHODS This study included 457 children with CIs and 131 children with NH, who completed t...
Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
introduction: the purpose of this study was to compare the heat generated from different depths of an implant drilling site with and without a sleeve. materials and methods: in this study, 60 cortical bone samples were used and a load of 2.0 kg was applied. rilling for implant surgery, we used a diameter of 4.3 mm and a normal sleeve. heat was measured from 3 different depths(3,6, and 9 mms). d...
