Comet assay: A brief history
(2009) -
Dietary habits of Greek primary school children
(2007)The purpose of this study was to assess Greek primary (1st to 6th grade) school children's dietary habits and the factors influencing them. Our results show that children know the value of different foods. The socio-economic ... -
DNA damage and repair capacity in lymphocytes from obstructive sleep apnea patients
(2007)Obstructive sleep apnea (OSA) syndrome is a respiratory disease that is linked to heart attacks and high blood pressure. In the present study, we used the Comet assay to compare basal DNA damage and DNA damage induction ... -
DNA damage and repair efficiency in lymphocytes from schizophrenic patients
(2004)In the present study we examined schizophrenic patients' lymphocytes sensitivity to the effects of external factors, such as hydrogen peroxide and gamma-irradiation and also their repair efficiency with the comet assay. ... -
DNA damage and repair in obstructive sleep apnea syndrome
(2005)The Obstructive Sleep Apnea is a respiratory disorder characterized by short breathing pauses during sleep. These pauses vary according to the Apnea type and the severity of the case. People suffering from Obstructive Sleep ... -
DNA damage in a human population affected by chronic psychogenic stress
(2003)The effects of chronic psychogenic stress on the expression of DNA damage and cellular response to the damage were investigated. Using the comet assay, basal DNA damage was found to be similar in lymphocytes of both affected ... -
Effect of external classroom noise on schoolchildren's reading and mathematics performance: Correlation of noise levels and gender
(2015)The present study investigated the effect of low, medium, and high traffic road noise as well as irrelevant background speech noise on primary school children's reading and mathematical performance. A total of 676 participants ... -
Effects of pesticides on exposed populations from four European countries
(2008)The potential genetic hazard of pesticides to humans is of great concern, in particular in occupational and environmental settings because of their widespread use for domestic and industrial applications. In the present ... -
Effects of pesticides on occupationally exposed humans
(2006)Pesticides are known to contain numerous genotoxic compounds; however, genotoxicity biomonitoring studies of workers occupationally exposed to pesticides have produced variable results. In this study, we employed the Comet ... -
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 ... -
Greek elementary school children's beliefs about long-term effects of drinking and smoking
(2010)Tobacco use and alcohol consumption are two of the most hazardous habits, leading to serious health problems. The present study aimed at investigating Greek elementary school children's conceptions regarding the effects ... -
Investigation of the Genotoxic Effect of Pesticides on Greenhouse Workers' Lymphocytes
(2009)In the present study, the genotoxic effects of commonly applied pesticides were evaluated using the alkaline comet assay (pH > 13). The amount of DNA damage (% DNA in tail) in peripheral lymphocytes of 49 male agricultural ... -
Measuring the effects of pesticides on occupationally exposed humans with the comet assay
(2006)In this study we examine the effects of a mixture of pesticides on occupationally exposed agricultural workers. The study was performed on 149 people, 84 agricultural workers and 65 healthy men from the same area, who ... -
Noise and perceived discomfort in Greek school children
(2013)The survey herein aims to record the types of noise that school children frequently encounter at school (both indoors and outdoors), to investigate the degree of distress and to record the views of school children as to ... -
Pathophysiologic factors of bronchial asthma in childhood
(2006)In this report we analyzed in detail asthma, which is a reactive airway disease, is a leading cause of chronic illness in childhood. Important pathophysiologic factors are the bronhoconstriction and inflammation. T ... -
Serotonin and personality: How does serotonin relate to impulsivity and aggression?
(2007)The present article investigated the relationship between serotonin (5-HT) and personality. In particular, we examined the effect that serotonin has on impulsivity and aggression. Different neurotransmitters seem to affect ... -
The stigmatization of obesity in children. A survey in Greek elementary schools
(2009)This study investigates elementary school children's prejudice towards obesity. A sample of 1861 underweight, normal, overweight and obese children from Central Greece were instructed to rank 6 drawings of same sex children ... -
Stress and the progression of HIV disease
(2006)The reciprocal interactions between the neuroendocrine, immune, and autonomic nervous system are complicated, yet worthy of examination. A body of literature suggests that psychological factors such as stress, or psychiatric ... -
The use of comet assay in measuring DNA damage and repair efficiency in child, adult, and old age populations
(2009)In the present study, we used the Comet assay to estimate basal DNA damage in three distinct populations aged 5-10, 40-50, and 60-70 years old. The DNA damage induced by hydrogen peroxide and gamma-irradiation in the ...
