The acute effect of smoking in healthy and asthmatic smokers
(2010)Background Acute exposure to cigarette smoke is related to airway and systemic inflammation and oxidative stress. Little is known about the acute effect of cigarette smoking in smoking asthmatics. The aim of this study was ... -
Antioxidant capacity in obstructive sleep apnea patients
(2003)Objectives: Obstructive sleep apnea syndrome (OSA) results in oxygen desaturation and arousal from sleep. Free oxygen radicals are highly reactive molecules, which can be produced by the OSA phenomenon known as ... -
Assessment of antioxidant/anticarcinogenic activity of plant extracts by a combination of molecular methods
(2005)Cancer chemoprevention is considered to be a promising approach for cancer control, as it has been identified by both epidemiological and molecular studies that environmental factors are the major causes of cancer. ... -
Blood reflects tissue oxidative stress: a systematic review
(2015)We examined whether the levels of oxidative stress biomarkers measured in blood reflect the tissue redox status. Data from studies that measured redox biomarkers in blood, heart, liver, kidney and skeletal muscle were ... -
Diagnostic accuracy of biomarkers of oxidative stress in parapneumonic pleural effusions
(2011)P>Background The imbalance between oxidants and antioxidants is referred to as oxidative stress and has been associated with various respiratory disorders. The aim of this study was the assessment of 8-isoprostane (8-iso-PGF(2 ... -
Differential effects of xanthine oxidase inhibition and exercise on albumin concentration in rat tissues
(2010)Albumin is a protein present in almost all kinds of mammalian cells. It has binding sites for several molecules, and possesses antioxidant and other important properties. The aim of this study was to examine the effects ... -
Effect of 1-year oral alpha-tocopherol administration on anticardiolipin antibodies in hemodialysis patients
(2005)Background. Anticardiolipin antibodies (ACA) have been related to an increased incidence of thrombotic episodes and atherosclerosis progression. ACA levels are elevated in hemodialysis (HD) patients. Atheroembolic episodes ... -
Effects of polyphenolic grape extract on the oxidative status of muscle and endothelial cells
(2014)A grape pomace extract enhanced antioxidant mechanisms in muscle and endothelial cells both in the absence and in the presence of oxidative stress-induced agent tert-butyl hydroperoxide (tBHP). In particular, muscle (C2C12) ... -
Exercise as a model to study redox homeostasis in blood: the effect of protocol and sampling point
(2012)Twenty males ran either on a level treadmill (nonmuscle-damaging condition) or on a downhill treadmill (muscle-damaging condition). Blood and urine samples were collected before and after exercise (immediately after, 1h, ... -
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. ... -
Favorable and prolonged changes in blood lipid profile after muscle-damaging exercise
(2008)Purpose: To examine the effect of repeated muscle-damaging exercise on the time-course changes in blood lipid and lipoprotein profile and compare them with changes in indices of muscle function and damage. Methods: Twelve ... -
Grape pomace extract exerts antioxidant effects through an increase in GCS levels and GST activity in muscle and endothelial cells
(2015)In a previous study, we demonstrated that a grape pomace extract (GPE) exerted antioxidant activity in endothelial (EA. hy926) and muscle (C2C12) cells through an increase in glutathione (GSH) levels. In the present study, ... -
Increased oxidative stress in exudative pleural effusions - A new marker for the differentiation between exudates and transudates?
(2005)Study objectives: Oxidative stress has been associated with various respiratory disorders. We tested the hypothesis that exudates would present higher levels of oxidative stress compared to transudates, expressing the ... -
Interactions of Obstructive Sleep-Disordered Breathing With Recurrent Wheezing or Asthma and Their Effects on Sleep Quality
(2011)Snoring is the most characteristic symptom of obstructive sleep-disordered breathing ( SDB) and recurrent wheezing is the most common clinical manifestation of asthma. The purpose of the present review is to outline the ... -
The microcycle of inflammation and performance changes after a basketball match
(2014)Basketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle ... -
A MICROCYCLE OF INFLAMMATION FOLLOWING A TEAM HANDBALL GAME
(2014)Chatzinikolaou, A, Christoforidis, C, Avloniti, A, Draganidis, D, Jamurtas, AZ, Stampoulis, T, Ermidis, G, Sovatzidis, A, Papassotiriou, I, Kambas, A, and Fatouros, IG. A microcycle of inflammation following a team handball ... -
Oxidative Stress and Reduced Antioxidative Status, along with Endothelial Dysfunction in Acromegaly
(2013)Acromegaly is characterized by high cardiovascular morbidity and mortality. Oxidative stress and endothelial dysfunction are underlying mechanisms of atherosclerosis. The aim of this study was to evaluate the blood redox ... -
Oxidative stress biomarkers responses to physical overtraining: Implications for diagnosis
(2007)Overtraining syndrome is characterized by declining performance and transient inflammation following periods of severe training with major health implications for the athletes. Currently, there is no single diagnostic ... -
Passive smoking, asthma and allergy in children
(2009)Despite the recent campaigns to eliminate smoking and hinder the detrimental effects of passive smoking (PS), actual smoking rates still increase worldwide. Several physiological systems, with the respiratory being the ...
