Application of Solid oxide proton-conducting electrolytes for amperometric analysis of hydrogen in H-2+N-2+H2O gas mixtures
(2014)Amperometric hydrogen sensors based on proton-conducting solid electrolytes of La0.95Sr0.05YO3, CaTi0.95Sc0.05O3 and CaZr0.9Sc0.1O3 compositions are prepared and investigated in the present work. The influence of the sensor ... -
Association between primary nocturnal enuresis and habitual snoring in children
(2006)Objectives. Nocturnal enuresis has been associated with obstructive sleep-disordered breathing mostly in hospital-referred adults and children. To investigate whether primary nocturnal enuresis is significantly associated ... -
Benign esophageal stricture in the dog and cat: A retrospective study of 20 cases
(2002)Twenty animals with benign esophageal strictures are presented. Most of the esophageal strictures were thought to be related to gastroesophageal reflux during ovariohysterectomy and were located at the distal portion of ... -
BENIGN POSTPARTUM PLEURAL EFFUSION
(1995)The conditions of labour appear to favour the development of pleural effusion, The frequency of postpartum pleural effusion was investigated in this study using thoracic ultrasonography. Thirty one postpartum and 22 healthy ... -
Blood flow measurements within optic nerve head during on-pump cardiovascular operations. A window to the brain?
(2011)This observational study is conducted to demonstrate optic nerve head (ONH) blood flow alterations during extracorporeal circulation (ECC) in routine on-pump cardiovascular operations in order to evaluate the perfusion ... -
Computational phlebology: reviewing computer models of the venous system
(2013)Relatively little attention has been paid to the venous system and valves from a cardiovascular engineering perspective up to now. Given the involvement of venous valve haemodynamics in the development of deep vein thrombosis ... -
Effects of adenotonsillectomy on R-R interval and brain natriuretic peptide levels in children with sleep apnea: A preliminary report
(2011)Objectives: Obstructive sleep apnea is associated with decreased R-R interval length and overall R-R interval variability in the electrocardiogram along with increased morning brain natriuretic peptide (BNP) blood levels. ... -
End corrections for rarefied gas flows through capillaries of finite length
(2013)The influence of end effects on rarefied gas flows through moderately long capillaries is investigated by implementing the concept of effective capillary length, representing a sum of the real length of capillary and its ... -
Endothelial Progenitor Cells in the Pathogenesis of Idiopathic Pulmonary Fibrosis: An Evolving Concept
(2013)Background: Idiopathic pulmonary fibrosis (IPF) has been associated with abnormal vascular remodeling. Bone marrow derived endothelial progenitor cells (EPCs) are considered to possess lung tissue repair and vascular ... -
Finite element simulation of the mechanical impact of computer work on the carpal tunnel syndrome
(2014)Carpal tunnel syndrome (CTS) is a clinical disorder resulting from the compression of the median nerve. The available evidence regarding the association between computer use and CTS is controversial. There is some evidence ... -
Mechanical behavior and wrinkling of lined pipes
(2012)The paper focuses on wrinkling of lined pipes (sometimes referred to as clad pipes) under bending loading, where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The problem is solved ... -
No effect of antioxidant supplementation on muscle performance and blood redox status adaptations to eccentric training
(2011)Background: It was recently reported that antioxidant supplementation decreases training efficiency and prevents cellular adaptations to chronic exercise. Objective: This study aimed to investigate the effects of vitamin ... -
Obstructive sleep-disordered breathing and fasting insulin levels in nonobese children
(2005)A positive correlation of severity of sleep-disordered breathing with morning fasting insulin levels, which is independent of obesity, was reported in adults and obese children. We hypothesized that both severity of ... -
Ornamental fish in pet stores in Greece: a threat to biodiversity?
(2014)The aquarium trade has been recognized as an important pathway for the introduction of invasive species around the world. This study investigates the availability of ornamental fish species in ten large-size, centrally ... -
Overnight change in brain natriuretic peptide levels in children with sleep-disordered breathing
(2006)Study objectives: Obstructive sleep-disordered breathing is accompanied by episodic increases in left ventricle afterload due to large negative swings in intrathoracic pressure and repetitive surges in arterial pressure. ... -
Oxidative stress and inflammatory markers in the exhaled breath condensate of children with OSA
(2012)Obstructive sleep apnea (OSA) in children has been associated with systemic inflammation and oxidative stress. Limited evidence indicates that pediatric OSA is associated with oxidative stress and inflammation in the airway. ... -
Prevalence of Pulmonary Hypertension in Patients with Idiopathic Pulmonary Fibrosis: Correlation with Physiological Parameters
(2011)The aim of this study was to prospectively evaluate the prevalence of pulmonary hypertension (PH) in patients with idiopathic pulmonary fibrosis (IPF). One hundred thirty-nine patients (101 male, mean age = 68.6 +/- A 9 ... -
Retrograde cardioplegia in CABG: Is it really useful? The microcirculation and a capillary unit model
(2006)Most surgeons, ourselves including, use retrograde cardioplegia in numerable operations in cardiac surgery. It is believed to be not only supplementary to antegrade, but also a unique alternative in special complicated ... -
Risk factors for enterococcal infection and colonization by vancomycin-resistant enterococci in critically ill patients
(2014)Vancomycin-Resistant Enterococci (VRE) are important causes of Intensive Care Unit (ICU) infections. Our goal was to identify the prevalence and risk factors for VRE colonization upon ICU admission and during ICU stay, as ...
