OBJECTIVES to investigate how the composition of the acquired enamel pellicle (AEP) affected a laboratory model of erosive tooth wear (ETW) on human enamel by comparing whole mouth saliva (WMS) to parotid saliva (PS). METHODS 60 enamel specimens were prepared from extracted human teeth and were randomly assigned to 4 experimental groups WMS (n = 20), PS (n = 20), artificial saliva (AS, n = 10) and deionised water (DW, n = 10). Following incubation, a subset of WMS (n = 5) and PS (n = 5) groups were used to collect the AEP before the erosive challenge. The rest of the blocks, had their AEP collected after five cycles of acid, wash and saliva and were then assessed for mean step height changes using a non-contacting profilometer (n = 10 each). AEP samples were collected from the enamel specimens by rubbing with filter papers soaked in sodium dodecyl sulfate. Total protein in AEP was quantified using BCA assay, individual protein components of AEP were separated and analysed using SDS-PAGE and western blot for [re. SIGNIFICANCE The protective salivary proteins against in-vitro erosion models differ from in-vivo studies. Therfore, it can be recommended that in-vitro laboratory models of ETW need to be assessed carefully to represent the clinical environment more closely. OBJECTIVES This study investigated the in-vitro performance and fracture force of anterior implant-supported tooth-coloured fixed dental prosthesis (FDPs). Different material types with varying flexural strength and modulus of elasticity were compared with screw-retained or bonded application. MATERIALS AND METHODS Identical anterior FDPs (tooth 11-13; n = 80) from materials (flexural strength 240-1150 MPa, modulus 7.6-210 GPa; 1x lithiumdisilicate ceramic, 2x zirconia (4Y-TZP, 5Y-FSZ), 3x resin-based composites (with different flexural strength and modulus)) were milled. FDPs were grouped into chairside (bonded) and labside (screw-retained) procedure. To simulate a 5-year clinical application, thermal cycling with mechanical loading (TCML) was accomplished. TCML-performance and fracture force were evaluated and failure patterns were analysed. Data were statistically investigated (Kolmogorov-Smirnov-test, one-way-ANOVA; post-hoc-Bonferroni, α = 0.05). RESULTS TCML did not lead to any cracks, fractures or chiplant application. PK11007 research buy Superoxide dismutase 2 (SOD2) is a key enzyme for scavenging reactive oxygen species produced by mitochondria, which plays an important role in maintaining cellular homeostasis. However, its effects on the detoxification capability of liver cells have not been reported. In this study, we found that change in SOD2 expression affects the proliferation of liver cells. Genome-wide microarray analysis showed that SOD2 positively regulates the drug transporter ABCC2, and co-expression analysis suggested that lncRNA CLCA3P participates in the process. Further experiments showed that SOD2 can promote the expression of CLCA3P, which increases the transcription of ABCC2 by interacting with the transcription factor IRF1. By increasing ABCC2 expression SOD2 facilitates drugs efflux of liver cells and thus promotes their survival under a drug-toxic environment. This study elucidates the improvement of the detoxification of liver cells by a regulatory axis, SOD2-CLCA3P-IRF1-ABCC2, and provides novel insight into the modification of human liver cells that can be applied to bioartificial liver system or the study of SOD2 in drug metabolism. V.OBJECTIVE The present study aimed to determine the differential effects of intraoperative administration of milrinone versus levosimendan on myocardial function after pediatric cardiac surgery. Transthoracic echocardiography was used for myocardial function evaluation using biventricular longitudinal strain with 2-dimensional speckle tracking echocardiography in addition to conventional echocardiographic variables. DESIGN A secondary analysis of a randomized, prospective, double-blinded clinical drug trial. SETTING Two pediatric tertiary university hospitals. PARTICIPANTS Infants between 1 and 12 months old diagnosed with ventricular septal defect, complete atrioventricular septal defect, or tetralogy of Fallot who were scheduled for corrective surgery with cardiopulmonary bypass. INTERVENTIONS The patients were randomly assigned to receive an infusion of milrinone or levosimendan at the start of cardiopulmonary bypass and for 26 consecutive hours. MEASUREMENTS AND MAIN RESULTS Biventricular longitudinal strain and conventional echocardiographic variables were measured preoperatively, on the first postoperative morning, and before hospital discharge. The association between perioperative parameters and postoperative myocardial function also was investigated. Images were analyzed for left ventricular (n = 67) and right ventricular (n = 44) function. The day after surgery, left ventricular longitudinal strain deteriorated in both the milrinone and levosimendan groups (33% and 39%, respectively). The difference was not significant. The corresponding deterioration in right ventricular longitudinal strain was 42% and 50% (nonsignificant difference). For both groups, biventricular longitudinal strain approached preoperative values at hospital discharge. Preoperative N-terminal pro-brain natriuretic peptide could predict the left ventricular strain on postoperative day 1 (p = 0.014). CONCLUSIONS Levosimendan was comparable with milrinone for left and right ventricular inotropic support in pediatric cardiac surgery. Cystic echinococcosis (CE) is a zoonotic infection and could lead to significant public health problems. The genetic diversity of CE includes five species E. granulosus sensu stricto (s.s.) (G1-G3), Echinococcus equinus (G4), Echinococcus ortleppi (G5), Echinococcus canadensis genotypic cluster (G6, G7, G8 and G10, with the doubtful G9) and the Echinococcus felidis (lion strain). The species are important in epidemiology, pathology, control, prevention measures and vaccine/drug designs. The aim of the present study was to determine the E. granulosus genotypes in humans in the Van province in east of Turkey. In total, 102 echinococcal cysts were collected from operated patients. Genomic analyses were conducted with PCR-RFLP of the rDNA internal transcribed spacer 1 (ITS1) fragment and partial PCR sequencing of the cytochrome c oxidase subunit 1 (cox1) mitochondrial DNA gene region. In total, DNAs of 96 isolates could be extracted, unfortunately six extractions failed. The PCR-RFLP analysis findings were identical in all isolates.
