The aim of the present investigation was to calculate stress distribution generated in root dentine canal during mechanical rotation five different NiTi endodontic instruments by means a finite element analysis (FEA). Two conventional alloy F360 25/04 and F6 Skytaper 25/06, comparison three heat treated alloys NiTI Hyflex CM 25/04, Protaper Next 25/06 One Curve were considered analyzed. instrum...

This paper points out how the nonlinearities involved in multivariable Takagi–Sugeno (T–S) fuzzy control systems could originate complex behavior phenomena, such as multiple equilibrium points or limit cycles, that cannot be detected using conventional stability analysis techniques. In the paper, the application of MIMO frequency-domain methods to predict the existence of multiple equilibria an...

BACKGROUND Established indicators of central obesity include waist circumference, waist/height ratio, and the conicity index. Studies using such measures (as opposed to body mass index [BMI] percentiles) to characterize the association between obesity and asthma are lacking, despite the fact that these measures have been shown to be most relevant for many other chronic diseases. OBJECTIVES We...

BACKGROUND Limited data are available on left ventricle (LV) diastolic function in patients with ischemic dilated cardiomyopathy submitted to surgical ventricular restoration (SVR). The purpose of this study was to assess postoperative diastolic function changes and identify potential predictors of its worsening. METHODS One hundred and forty-six patients (65 +/- 9 years) with previous anteri...

Introduction: Abdominal deposition of fat has been described as the type of obesity that offers the greatest risk for the health of individuals, and is associated with increased mortality, and morbidity. Conicity index (Ci), Body mass index (BMI), and waist hip ratio (WHR) are used to predict the risk of obesity related diseases. However, it has not been examined whether these indicators can pr...

Objective: The objective of the present study was to examine the association of glucose intolerance and type-2 diabetes mellitus with the -174 G > C and -308 G > A allelic variations of IL-6 and TNF-α, respectively, through anthropometric measurements and age strata. Methods: This is a cross-sectional study using data from 285 community dwelling elderly women who underwent physical, biochemical...
