Analysis of miRNAs in endometrial fluid as a tool for non-invasive diagnosis of endometrial receptivity

2017

La implantación embrionaria es el proceso por el que el embrión humano en fase de blastocisto se adhiere al útero materno para comenzar la gestación. El endometrio, la mucosa uterina solo puede aceptar al embrión en un momento determinado del ciclo menstrual que puede variar entre 12 horas y 2 días, identificado como "ventana de implantación". Desde siempre se ha buscado la forma de identificar de forma fiable dicha ventana utilizando técnicas histológicas, como los criterios de Noyes, a través de la observación morfológica vía ecográfica, o estudiando los cambios en los perfiles transcriptómicos, proteómicos o metabolómicos. No obstante, en reproducción asistida, se está abriendo el camino…

Guidelines for biomarker discovery in endometrium: correcting for menstrual cycle bias reveals new genes associated with uterine disorders

2021

Abstract Transcriptomic approaches are increasingly used in reproductive medicine to identify candidate endometrial biomarkers. However, it is known that endometrial progression in the molecular biology of the menstrual cycle is a main factor that could affect the discovery of disorder-related genes. Therefore, the aim of this study was to systematically review current practices for considering the menstrual cycle effect and to demonstrate its bias in the identification of potential biomarkers. From the 35 studies meeting the criteria, 31.43% did not register the menstrual cycle phase. We analysed the menstrual cycle effect in 11 papers (including 12 studies) from Gene Expression Omnibus: t…

Is clinical experience important for obtaining the primary stability of dental implants with aggressive threads? An ex vivo study

2018

GECKILI, ONUR/0000-0002-7852-3915; dayan, suleyman cagatay/0000-0003-3081-9618; Bilhan, Hakan/0000-0003-1787-3003 WOS:000460131200015 PubMed ID: 30818319 Background: The aim of this study was to investigate the clinicians' experience on maintaining the primary stability of implants with aggressive threads belonging to a novel dental implant system. Material and Methods: Three hundred implants with aggressive threads were inserted in fresh bovine ribs mimicking Type IV bone by five clinicians which were classified according to their previous experience of total number of implant insertion. An independent examiner measured the primary stability of all implants after insertion by using resonan…

Subjective photic phenomena with refractive multifocal and monofocal intraocular lenses. results of a multicenter questionnaire.

2001

Abstract Purpose To compare the incidence and severity of photic phenomena after the implantation of the Array® (Allergan) refractive multifocal intraocular lens (MIOL) and a monofocal IOL. Setting Multicenter study at Kiel, Mainz, Karlsruhe, and Bremerhaven, Germany. Methods The study comprised 231 randomly selected patients from 4 study centers. The patients had had uneventful phacoemulsification with implantation of a refractive MIOL (n = 138) or a monofocal IOL (n = 93). By questionnaire, patients were asked whether they experienced light sensations postoperatively (light streaks, halos, flare, flashes, or glare) that had not been noticed preoperatively. Additional questions evaluated w…

Maternal-fetal cross-talk: elucidating the role of mir-30d in endometrial receptivity and pregnancy outcome

2018

Introducción En el proceso de implantación embrionaria se produce una relación sincrónica entre el endometrio y el embrión que resulta fundamental para su correcta consecución; dicha sincronía se mantiene durante la gestación gracias a la existencia de una comunicación bidireccional entre la madre y el feto basada en la secreción de señales específicas que permiten regular un desarrollo cooperativo. Efectivamente, se ha observado como el embrión libera moléculas específicas del estado gestacional (ej.: gonadotropina coriónica humana o interferón tau en rumiantes), para prevenir la luteólisis inducida por la prostaglandina F2alpha, posibilitando la secreción continua de progesterona durante …

Endothelial cells loss to the hyperopic pacients during phacoemulsification

2018

Introduction The phacoemulsification cataract surgery is the most frequently performed surgery and it generally improves vision in over 90% of the patients. Hyperopic patients are a challenge during phacoemulsification especially because of their short eyeball and shallow anterior chamber. A shallow anterior chamber is associated with overall reduction of the safe zone, which may lead to difficulty in creating the corneal incisions, harder capsulorhexis performing, or endothelial complications. Purpose The aim of the study was to present the endothelial cells loss after the phacoemulsification procedure in the hyperopic patients. Material and methods A number of 1775 patients operated in th…

Chronic Endometritis in Infertile Women: Impact of Untreated Disease, Plasma Cell Count and Antibiotic Therapy on IVF Outcome—A Systematic Review and…

2022

This systematic review and meta-analysis aims to evaluate the impact of chronic endometritis (CE) and its therapy on in vitro fertilization (IVF) outcome. Additionally, we aim to investigate whether various degrees of CE severity may exert a different effect on IVF outcome. Ongoing-pregnancy rate/live-birth-rate (OPR/LBR), clinical-pregnancy rate (CPR), and miscarriage rate (MR) were calculated. A total number of 4145 patients (from ten studies) were included. Women with CE had lower OPR/LBR (OR 1.97, p = 0.02) and CPR (OR 2.28, p = 0.002) compared to those without CE. CE cure increased OPR/LBR (OR 5.33, p < 0.0001) and CPR (OR 3.64, p = 0.0001). IVF outcome was comparable between women …

Assessing osseointegration of metallic implants with boronized surface treatment

2020

Background Modification of endosteal implants through surface treatments have been investigated to improve osseointegration. Boronization has demonstrated favorable mechanical properties, but limited studies have assessed translational, in vivo outcomes. This study investigated the effect of implant surface boronization on bone healing. Material and Methods Two implant surface roughness profiles (acid etched, machined) in CP titanium (type II) alloy implants were boronized by solid-state diffusion until 10-15µm boron coating was achieved. The surface-treated implants were placed bilaterally into 5 adult sheep ilia for three and six weeks. Four implant groups were tested: boronized machined …
