In vitro effects of two silicate-based materials, Biodentine and BioRoot RCS, on dental pulp stem cells in models of reactionary and reparative dentinogenesis.

Background: Calcium silicate-based cements are biomaterials with calcium oxide and carbonate filler additives. Their properties are close to those of dentin, making them useful in restorative dentistry and endodontics. The aim of this study was to evaluate the in vitro biological effects of two such calcium silicate cements, Biodentine (BD) and Bioroot (BR), on dental stem cells in both direct and indirect contact models.

Speech-in-speech perception and executive function involvement.

This present study investigated the link between speech-in-speech perception capacities and four executive function components: response suppression, inhibitory control, switching and working memory. We constructed a cross-modal semantic priming paradigm using a written target word and a spoken prime word, implemented in one of two concurrent auditory sentences (cocktail party situation). The prime and target were semantically related or unrelated.

Teaching invasive prenatal procedures: effectiveness of two simple simulators in training.

Background: Chorionic villus sampling (CVS) and amniocentesis are the major tools of invasive prenatal diagnosis. We studied the effectiveness of two simulators in training in invasive procedures.

Methods: Two affordable and simple simulators were developed, modelling the maternal abdomen and the different tissue layers crossed by the needle.

Effects of High-Temperature-Pressure Polymerized Resin-Infiltrated Ceramic Networks on Oral Stem Cells.

Objectives: The development of CAD-CAM techniques called for new materials suited to this technique and offering a safe and sustainable clinical implementation. The infiltration of resin in a ceramic network under high pressure and high temperature defines a new class of hybrid materials, namely polymer infiltrated ceramics network (PICN), for this purpose which requires to be evaluated biologically. We used oral stem cells (gingival and pulpal) as an in vitro experimental model.

Umbilical vein thrombosis: to deliver or not to deliver at the time of diagnosis?

Umbilical vein thrombosis is a rare anomaly with high mortality that frequently occurs in association with fetomaternal conditions. The unfavorable outcome of our case highlights the need for consensus on severity criteria, including the percentage of vascular occlusion determined by power Doppler, in order to improve outcome.

Case of a healthy infant born following antenatal enterovirus myocarditis and hydrops.

Fetal hydrops and myocarditis were diagnosed in a woman at 32 weeks of gestation (WG). Transplacental enterovirus infection was suspected because all other causes of myocarditis and hydrops were excluded, it was during an endemic period, and there was a setting of maternal infection (fever a few days before). We opted for in utero treatment because of the risk of resuscitating a neonate with myocarditis and hydrops.

Accuracy of ultrasonography and magnetic resonance imaging in the diagnosis of placenta accreta.

Purpose: To evaluate the accuracy of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of placenta accreta and to define the most relevant specific ultrasound and MRI features that may predict placental invasion.

Material And Methods: This study was approved by the institutional review board of the French College of Obstetricians and Gynecologists. We retrospectively reviewed the medical records of all patients referred for suspected placenta accreta to two university hospitals from 01/2001 to 05/2012.

Diagnosis of abdominal wall defects in the first trimester.

Purpose Of Review: To review prognostic parameters reported recently in the evaluation of abdominal wall defects in the first trimester.

Recent Findings: Evaluation of abdominal wall defects in the first trimester is based principally on associated structural or chromosomal anomalies. In the case of gastroschisis, which is rarely associated with other anomalies, evaluation of prenatal or postnatal outcome is based mainly on the course of pregnancy.

A case of congenital Echovirus 11 infection acquired early in pregnancy.

Enterovirus (EV) maternal infection during pregnancy and its relation to fetal developmental pathology are seldomly described. When reported, the main manifestations of EV congenital infections are myocarditis or intra-uterine fetal demise (IUFD). No information on intrauterine Echovirus 11 infection or the effect of transplacental Echovirus 11 infection on development of the fetus has been described in literature up to date (excluding late-pregnancy infections).

Using metabolomics to monitor kidney transplantation patients by means of clustering to spot anomalous patient behavior.

Background: NMR spectroscopy-based metabolomics is a system approach used to investigate the metabolic profile of biological fluids with multivariate data analysis tools. The aim of this study was to examine the kidney graft recovery process noninvasively through the examinations of urine samples using (1)H NMR spectroscopy combined with chemometric tools.

Methods: Urine samples were treated as the source of metabolites reflecting the pathological and clinical conditions of patients with transplanted kidneys.

Fabrication of Fe-wings used for micro imprinting with a natural butterfly wing structure by in situ carbothermic reduction.

We demonstrate a simple and promising method for the preparation of large-area natural microstructured Fe-wings which combines biotemplating and biomimetic techniques using natural structures as templates. The replicas were robust and hydrophobic, and also possessed excellent magnetic properties. The micro-structures of the wing scales were accurately retained.

Omphalocele in the first trimester: prediction of perinatal outcome.

Objective: This study aims to evaluate the perinatal outcomes of fetuses with isolated omphalocele diagnosed before 14 weeks of gestation (WG) and determine whether visceral-abdominal disproportion (ratio between mean omphalocele diameter and transverse abdominal diameter) and omphalocele contents can predict neonatal morbidity.

Methods: This is a retrospective cohort study of omphaloceles diagnosed before 14 WG at three tertiary centers between January 1998 and January 2010. In the group of isolated omphaloceles (i.

Got rhythm…for better and for worse. Cross-modal effects of auditory rhythm on visual word recognition.

The present research aimed to investigate whether, as previously observed with pictures, background auditory rhythm would also influence visual word recognition. In a lexical decision task, participants were presented with bisyllabic visual words, segmented into two successive groups of letters, while an irrelevant strongly metric auditory sequence was played in a loop. The first group of letters could either be congruent with the syllabic division of the word (e.

[Protein C deficiency in patient with sepsis-associated disseminated intravascular coagulation and deep vein thrombosis].

Disseminate intravascular coagulation (DIC) is a clinical pathological syndrome associated to several diseases. Sepsis is the most common cause in infants and children. DIC results from the anomalous activation of blood coagulation, widespread formation of thrombi in the microcirculation, and consumption of clotting factors and platelets.

[Amniocentesis trainer: development of a cheap and reproducible new training model].

Amniocentesis is the most common invasive procedure for prenatal diagnosis. It is essential to master this sampling technique prior to performing more complex ultrasound-guided interventions (cordocentesis, drain insertion). Training is a challenge because of the risks associated with the procedure, as well as the impact on the patient's anxiety.
