Effect of ProRoot MTA® and Biodentine® on osteoclastic differentiation and activity of mouse bone marrow macrophages

J. appl. oral sci; 27 (), 2019
Abstract Objectives This investigation aimed to assess the differentiation inhibitory effects of ProRoot MTA® (PMTA) and Biodentine® (BIOD) on osteoclasts originated from murine bone marrow macrophages (BMMs) and compare these effects with those of alendronate (ALD). Materials and Methods Mouse BMMs ...

Stanozolol promotes osteogenic gene expression and apposition of bone mineral in vitro

J. appl. oral sci; 27 (), 2019
Abstract Stanozolol (ST) is a synthetic androgen with high anabolic potential. Although it is known that androgens play a positive role in bone metabolism, ST action on bone cells has not been sufficiently tested to support its clinical use for bone augmentation procedures. Objective: This study aimed to...

Inhibitory effect of Astragalus polysaccharide on osteoporosis in ovariectomized rats by regulating FoxO3a /Wnt signaling pathway

Acta cir. bras; 34 (5), 2019
Abstract Purpose: To investigate inhibitory effect of Astragalus polysaccharide (APS) on osteoporosis in ovariectomized rats by regulating FoxO3a/Wnt2 signaling pathway. Methods: Postmenopausal osteoporosis (PMOP) animal model was developed by excising the bilateral ovaries of rats. The model rats we...

The role of ischemic preconditioning in the expression of apoptosis-related genes in a rat model of intestinal ischemia-reperfusion injury

Acta cir. bras; 34 (5), 2019
Abstract Purpose: To analyze the effects of ischemic preconditioning (IPC) in the expression of apoptosis-related genes in rat small intestine subjected to ischemia and reperfusion. Methods: Thirty anesthetized rats underwent laparotomy and were drive into five groups: control (CG); ischemia (IG); is...

Expression analysis of long non-coding RNAs in a renal ischemia-reperfusion injury model

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To investigate the long non-coding RNAs (lncRNAs) profile on renal ischemia reperfusion in a mouse model. Methods: Microarray analysis was used to study the expression of misregulated lncRNA in a mouse model of renal ischemia reperfusion(I/R) with long ischemia time. Quantitative re...

Comparison of GeneXpert MTB/RIF assay and LED-FM microscopy for the diagnosis of extra pulmonary tuberculosis in Khyber Pakhtunkhwa, Pakistan

Braz. j. microbiol; 49 (4), 2018
ABSTRACT GeneXpert is one of the recent technological instruments used to diagnose tuberculosis in a short span of time. In this study, the performance of GeneXpert MTB/RIF assay for the diagnosis of extrapulmonary tuberculosis (EPTB) was compared with light-emitting diode Fluorescent Microscopy (LED-FM)...

Fluctuations in serological hepatitis C virus levels in HIV patients

Abstract INTRODUCTION: Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) have identical transmission routes, explaining the high prevalence of coinfections. The main aim of this study was to detect fluctuations in serological HCV levels in HIV patients. METHODS: We analyzed samples of 14...

Absence of cytomegalovirus in gingivitis and chronic periodontitis in HIV-1 patients in Northern Brazil

Abstract INTRODUCTION The influence of cytomegalovirus (CMV) on the progression of chronic periodontitis in HIV patients is poorly investigated. METHODS ELISA was used for anti-CMV antibody IgG titer measurements and real-time polymerase chain reaction for qualitative and quantitative CMV detection. ...

Introducción de nuevos ensayos de reacción en cadena de la polimerasa en tiempo real para el diagnóstico y vigilancia de virus respiratorios
Introduction of new assays of real time polymerase's chain reaction for the diagnosis and surveillance of respiratory viruses

Rev. cuba. med. trop; 70 (3), 2018
Las infecciones respiratorias agudas constituyen la causa fundamental de mortalidad y morbilidad en el ámbito mundial. Los principales agentes causales de estas infecciones son los virus. La detección rápida y eficaz de estos patógenos es determinante en el tratamiento y la prevención de las enferme...

Acta cir. bras; 33 (12), 2018
Abstract Purpose: To investigate the gene expression related to inflammation on mice subjected to intestinal ischemia and reperfusion (I/R) and treated with ischemic preconditioning (IPC). Methods: Thirty rats (EPM-Wistar), distributed in five groups of six animals each, were underwent anesthesia and...
