Exercise-induced regulation of redox status in cardiovascular diseases: The role of exercise training and detraining
(2020)Although low levels of reactive oxygen species (ROS) are beneficial for the organism ensuring normal cell and vascular function, the overproduction of ROS and increased oxidative stress levels play a significant role in ... -
Exercising with passion: Initial validation of the passion scale in exercise
(2012)The purpose of the researchers in the study was to psychometrically evaluate Passion Scale scores (Vallerand et al., 2003) in exercise. Self-report data were collected from two samples of Greek exercise participants. Sample ... -
Exergames and implications on quality of life in pediatric oncology patients: A preliminary qualitative study
(2019)The purpose of the study was to investigate the effect of exergames on the quality of life of three pediatric oncology patients and their attitudes towards participation in physical activity after the end of the program. ... -
An exergetic analysis of an ethanol FED SOFC-GT hybrid system
(2009)A parametric analysis optimization and comparison of the exergetic efficiency (2nd law) of two different Solid Oxide Fuel Cell based power plants (SOFC-GT and SOFC) is carried out in the present work. The fuel with which ... -
Exergetic and economic analysis of a cheese whey wastewater anaerobic treatment plant with a cogeneration system
(2014)This paper investigates the extension of an existing steam production plant in order to cover both thermal and electrical needs of a factory. The plant uses biogas produced from cheese whey (CW) wastewater anaerobic digestion ... -
Exergetic potential of fuels: The case of a SOFC-based power plant
(2004)The method of exergy analysis is presented for a SOFC power plant involving external steam reforming and fed by methane and ethanol. The optimal operation parameters of the integrated SOFC plant are specified after minimizing ... -
Exergy analysis of a hybrid micro gas turbine fuel cell system based on existing components
(2012)A hybrid system based on an existing recuperated micro-turbine and a pre-commercially available high temperature tubular solid oxide fuel cell is modeled in order to study its performance. Individual models are developed ... -
Exergy analysis of a solid oxide fuel cell power plant fed by either ethanol or methane
(2004)The method of exergy analysis is presented for a solid oxide fuel cell (SOFC) power plant involving external steam reforming and fed by methane and ethanol. The parameters for optimal operation of the integrated SOFC plant ... -
Exergy analysis of an ethanol fuelled proton exchange membrane (PEM) fuel cell system for automobile applications
(2005)An integrated ethanol fuelled proton exchange membrane fuel cell (PEMFC) power system was investigated following a second law exergy analysis. The system was assumed to have the typical design for automobile applications ... -
Exergy Analysis of an Intermediate Temperature Solid Oxide Fuel Cell-Gas Turbine Hybrid System Fed with Ethanol
(2012)In the present work, an ethanol fed Solid Oxide Fuel Cell-Gas Turbine ( SOFC-GT) system has been parametrically analyzed in terms of exergy and compared with a single SOFC system. The solid oxide fuel cell was fed with ... -
Exertional Hypoxemia in Stable COPD Is Common and Predicted by Circulating Proadrenomedullin
(2014)BACKGROUND: The prevalence of exertional hypoxemia in unselected patients with COPD is unknown. Intermittent hypoxia leads to adrenomedullin (ADM) upregulation through the hypoxia-inducible factor-1 pathway. We aimed to ... -
Exhaled breath condensate in asthma: From bench to bedside
(2011)The need for non-invasive assessment of airway inflammation is imperative, since inflammatory airway diseases, such as asthma and COPD, are characterized by variation in their clinical presentation throughout their course. ... -
Exhaled breath condensate in patients with asthma: implications for application in clinical practice
(2008)Exhaled breath condensate (EBC) analysis, a rather appealing and promising method, can be used to evaluate conveniently and non-invasively a wide range of molecules from the respiratory tract, and to understand better the ... -
Exhaled breath condensate pH as a biomarker of COPD severity in ex-smokers
(2011)Endogenous airway acidification, as assessed by exhaled breath condensate (EBC) pH, is present in patients with stable COPD. The aim of this study was to measure EBC pH levels in a large cohort of COPD patients and to ... -
Exhaled Nitric Oxide (FeNO) in Patients Hospitalized for an Exacerbation of Bronchiectasis and/or COPD: FeNO Levels in COPD and Bronchiectasis
(2021)Exhaled nitric oxide (FeNO) represents an important marker of airway inflammation, yet its role in chronic obstructive pulmonary disease (COPD) and/or bronchiectasis is not well studied. We aimed to measure FeNO in patients ... -
Exhaled nitric oxide as a marker of chlorine exposure in young asthmatic swimmers
(2019)Background: Swimming is recommended for people with asthma. However, the inevitable exposure to chlorine and its disinfectant byproducts in indoor swimming pools could be responsible for bronchial inflammation and asthma ... -
Exhaled Nitric Oxide in Asthma in Adults: The End is the Beginning?
(2011)Approximately 20 years after the initial report of the measurement of exhaled nitric oxide (NO) in the exhaled air of humans, numerous publications have evaluated the possible applications of the fraction of exhaled NO ... -
Exhaled NO and exhaled breath condensate pH in the evaluation of asthma control
(2011)Background: Asthma is a chronic inflammatory airways disorder. However, no biomarker of airways inflammation has been included in the assessment of asthma control. Objective: To evaluate exhaled NO (FeNO) and exhaled breath ... -
Existence and Congruence of Global Attractors for Damped and Forced Integrable and Nonintegrable Discrete Nonlinear Schrödinger Equations
(2021)We study two damped and forced discrete nonlinear Schrödinger equations on the one-dimensional infinite lattice. Without damping and forcing they are represented by the integrable Ablowitz-Ladik equation (AL) featuring ...
