Effects of MTA and Brazilian propolis on the biological properties of dental pulp cells

Abstract: The aim of this study was to evaluate the effect of mineral trioxide aggregate (MTA) and Brazilian propolis on the cell viability, mineralization, anti-inflammatory ability, and migration of human dental pulp cells (hDPCs). The cell viability was evaluated with CCK-8 kit after 1, 5, 7, and 9 da...

Estandarización de la técnica Real Time PCR para la detección molecular de la mutación V617F en el gen de JAK-2 en neoplasias mieloproliferativas crónicas
Standardization of the Real Time PCR technique for the molecular detection of the V617F mutation in the JAK-2 gene in chronic myeloproliferative neoplasms

V617F mutation in exon 14 of Janus Kinase 2 gene (jak-2) is used as a molecular marker for the diagnosis of Philadelphia negative myeloproliferative neoplasms (Phi-) such as Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (MFP). To detect this mutation, we ...

ErbB1 and ErbB3 co-over expression as a prognostic factor in gastric cancer

Biol. Res; 52 (), 2019
BACKGROUND: Epidermal growth factor receptor family members such as ErbB1 and ErbB3 are involved in tumor progression and metastasis. Although, there are various reports about the prognostic value of EGFR members separately in gastric cancer, there is not any report about the probable correlation between...

IRF2-INPP4B-mediated autophagy suppresses apoptosis in acute myeloid leukemia cells

Biol. Res; 52 (), 2019
BACKGROUND: The present study aimed to investigate the underlying role of interferon-regulatory factor 2 (IRF2)-inositol polyphosphate-4-phosphatase, type-II (INPP4B) axis in the regulation of autophagy in acute myeloid leukemia (AML) cells. METHODS: Quantitative real time PCR (QRT-PCR) and western blot ...

DNA hypermethylation of Fgf16 and Tbx22 associated with cleft palate during palatal fusion

J. appl. oral sci; 27 (), 2019
Abstract Objective: Cleft palate (CP) is a congenital birth defect caused by the failure of palatal fusion. Little is known about the potential role of DNA methylation in the pathogenesis of CP. This study aimed to explore the potential role of DNA methylation in the mechanism of CP. Methodology: We es...

Quantification of pro-inflammatory cytokines and osteoclastogenesis markers in successful and failed orthodontic mini-implants

J. appl. oral sci; 27 (), 2019
Abstract Objectives: Miniscrew has been frequently used, considering that anchorage control is a critical point in orthodontic treatment, and its failure, the main adverse problem. Using two groups of stable (successful) and unstable (failed) mini-implants, this in vivo study aimed to quantify proinflam...

Evolutionary study of potentially zoonotic hepatitis E virus genotype 3 from swine in Northeast Brazil

Mem. Inst. Oswaldo Cruz; 114 (), 2019
Hepatitis E virus (HEV), an emerging virus associated with acute hepatic disease, leads to thousands of deaths worldwide. HEV has already been reported in Brazil; however, there is a lack of epidemiological and molecular information on the genetic variability, taxonomy, and evolution of HEV. It is thus u...

Syphilis in female sex workers: an epidemiological study of the highway system of the state of Pará, northern Brazil

Abstract INTRODUCTION: Female sex workers (FSWs) are considered a bridge for transmission of pathogens from high-risk to general populations. We assessed the epidemiological status of syphilis in FSWs along the Pará highway system. METHODS: Two hundred and twenty-two FSWs were interviewed and sample...

Viral etiology of acute respiratory infections in children in Southern Iran

Abstract INTRODUCTION: Prevalence of influenza A virus (Flu-A), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) was assessed in children with acute respiratory infections (ARIs). METHODS: Nasopharyngeal aspirates and throat swabs were subjected to real-time polymerase chain reaction...

Standardization of antigenemia and qpcr cut-off values in whole blood for the detection of cytomegalovirus disease in hiv patients

Abstract INTRODUCTION: We defined the cut-off values of the antigenemia and cytomegalovirus (CMV) DNA tests in HIV/AIDS patients to identify CMV disease. METHODS: A total of 97 samples from 68 patients with and without CMV disease were analyzed by viral DNA detection and antigenemia assay. RESULTS: Q...
