Acute exercise markedly increases blood oxidative stress in boys and girls
(2007)This study investigated the effect of an acute swimming protocol on selected blood redox status indices in trained children. Eleven boys and 11 girls (aged 9-11 y) swam 12 bouts of 50 m at a pace corresponding to 70%-75% ... -
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 ... -
Antioxidant effects of whey protein on muscle C2C12 cells
(2014)In the present study, the in vitro scavenging activity of sheep whey protein against free radicals, as well as its reducing power were determined and compared with that of beef protein, soy protein and cow whey protein. ... -
Assessment of antioxidant activity of extracts from unique Greek varieties of Leguminosae plants using in vitro assays
(2007)Background: It is believed that legumes are a very good source of micronutrients and phytochemicals that present chemopreventive activity against diseases such as diabetes, coronary heart disease and colon cancer. Methanolic ... -
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. ... -
Assessment of Oxidative Stress in Septic and Obese Patients Using Markers of Oxidation-reduction Potential
(2015)Background/ Aim: The novel static (sORP) and capacity (cORP) oxidation-reduction potential markers were examined for assessing oxidative stress in plasma of patients with sepsis. Moreover, the possible effect of obesity-induced ... -
Blood reflects tissue oxidative stress depending on biomarker and tissue studied
(2009)This study investigated whether selected oxidative stress markers measured in blood adequately reflect redox status in skeletal muscle, heart, and liver. Several markers were determined after implementing two treatments ... -
A brief exposure to low pH prior to refrigerated storage reduces the motility and viability of goldfish sperm (Carassius auratus, Linnaeus, 1758)
(2015)Optimal conditions of short-term storage of fish sperm are important for successful artificial reproduction protocols or incubation of sperm in a cryoprotecting medium for successful sperm cryopreservation. The influence ... -
Cardiotoxicity in rabbits after a low-level exposure to diazinon, propoxur, and chlorpyrifos
(2014)Lethal cardiac complications leading to death and various arrhythmias have been reported after organophosphate and/or carbamate poisonings. The present study focuses on the long-term effects of repeated low-level exposure ... -
Effect of a special carbohydrate-protein cake on oxidative stress markers after exhaustive cycling in humans
(2012)Exercise has been associated with oxidative stress that is correlated with muscle fatigue and reduced exercise performance. The aim of this study was to examine the effects of a special cake (consisting of carbohydrate to ... -
Effect of exercise on oxidative stress in individuals with glucose-6-phosphate dehydrogenase deficiency
(2006)The effect of exercise on oxidative stress in glucosee-phosphate dehydrogenase (G6PD)-deficient individuals was investigated. Materials and Methods: Nine G6PD-deficient males and nine males with normal G6PD activity were ... -
Effects of pulsed electric fields on DNA of human lymphocytes
(2006)The effects of pulsed electric fields of low frequency (50 Hz) on DNA of human lymphocytes were investigated. The influence of additional external factors, such as hydrogen peroxide (H2O2) and gamma-irradiation, as well ... -
Exercise-induced oxidative stress in G6PD-deficient individuals
(2006)Purpose: This study was designed to investigate whether individuals with glucose-6phosphate dehydrogenase (G6PD) deficiency can exercise without greater perturbations in their redox status compared with non-G6PD-deficient ... -
Fatigue predictions in entire body of metallic structures from a limited number of vibration sensors using Kalman filtering
(2011)A methodology is proposed for estimating damage accumulation due to fatigue in the entire body of a metallic structure using output-only vibration measurements from a sensor network installed at a limited number of structural ... -
Hierarchical Bayesian model updating for structural identification
(2015)A new probabilistic finite element (FE) model updating technique based on Hierarchical Bayesian modeling is proposed for identification of civil structural systems under changing ambient/environmental conditions. The ... -
High nitrate content in drinking water: Cytogenetic effects in exposed children
(1996)The potential genotoxicity of nitrates and nitrites-contaminants of drinking water that have been implicated in carcinogenesis-was investigated in this study. Sister chromatid exchanges and frequency of chromatid/chromosome ... -
Impaired degradation and aberrant phagocytosis of necrotic cell debris in the peripheral blood of patients with primary Sjogren's syndrome
(2015)Aberrant removal of necrotic debris is considered a feature with inflammatory consequences in SLE. Herein, primary Sjogren's syndrome (SS) patients were investigated for the first time for the capacity of their sera to ... -
Indentation of plastically graded substrates by sharp indentors
(2002)The present paper investigates the indentation of plastically graded substrates by sharp indentors. Contact analysis of plastically graded surfaces can be particularly useful in the design of load-bearing devices such as ... -
The influence of salt fog exposure on the fatigue performance of Alclad 6xxx aluminum alloys laser beam welded joints
(2010)Laser welding is increasingly used for the fabrication of lightweight and cost-effective integral stiffened panels in modern civil aircraft. As these structures age in service, the issue of the effect of corrosion on their ... -
Low-Frequency Fatigue as an Indicator of Eccentric Exercise-Induced Muscle Injury: The Role of Vitamin E
(2012)This study investigates whether vitamin E can attenuate eccentric exercise-induced soleus muscle injury as indicated by the amelioration of in situ isometric force decline following a low-frequency fatigue protocol ...
