“Oral Diseases (2012) 18, 786792 Objective: In the last two decades, the use of mobile phones has increased enormously all over the world.

The controversy regarding whether radiofrequency (RF) fields exert effects upon biological systems is a concern for the general population. An evaluation is made of DNA damage and cytokinetic defects, proliferative potential, and cell death because of RF radiation emitted by mobile phones in healthy young users. Study design: This cohort study was carried out in 50 Caucasian mobile phone users. We collected two cell samples from each subject (a total of 100 cell samples), corresponding to the right and left cheek mucosa, respectively. Case histories and personal information Mocetinostat mw were assessed, including age, gender,

body height and weight, history of cancer, smoking and alcohol consumption, exposure to chemical carcinogens or radiation, and dietary habits. Sampling comprised cell collection from both cheeks with a cytobrush, centrifugation, slide preparation, GW-572016 cost fixation, and staining, followed by fluorescent microscopic analysis. A total of 2000 exfoliated cells were screened for nuclear abnormalities, especially micronucleus. Results: No statistically significant changes were recorded in relation to age, gender, body mass index, or smoking status. A comparison of the results vs the control area according to the this website side of the face on which the mobile phone was placed, and in relation to the duration of exposure (years) to mobile phone radiation in the total 100 samples, yielded no significant differences. Conclusions: No genotoxic effects because of RF exposure were observed in relation to any of the study parameters.”
“Background: Slow heart rate recovery (HRR) after exercise is considered to represent impaired parasympathetic tone and to be a predictor of all-cause and cardiovascular mortality, but the independent value of abnormal

HRR in predicting the presence and severity of coronary artery disease (CAD) is unknown. The aim of this study was to evaluate these relationships in our patients.\n\nMethods: This prospective cross-sectional study included 208 patients (67.3% men), aged 34 to 74 (mean 53) years. Patients who had an ischemic response during symptom-limited exercise testing underwent selective coronary angiography. The value for HRR was defined as the decrease in heart rate from peak exercise to one minute after the exercise ceased. Eighteen beats per minute was defined as the lowest normal value for HRR.\n\nResults: Significant CAD was detected in 140 (67.3%) patients. There were 66 (31.7%) patients with an abnormal HRR.
