Aim: Electrocardiography is an important diagnostic tool in the evaluation of cardiac diseases. Normal electrocardiograms are age-dependent and may also vary due to several factors. Many studies have been performed to establish the normal values for the childhood period. The aim of this study was to determine the normal electrocardiograms values for healthy Turkish children in Aydın.
Material And Methods: All children underwent physical examination by a pediatrician and the electrocardiograms were analyzed by the same pediatrician. In the event of improper or insufficient data, the analyses were repeated. Children with a suspicious electrocardiograms or physical examination were recalled and examined by same pediatric cardiologist in outpatient clinic.
Results: In this study, electrocardiogram records were collected randomly from 1163 children with a sampling rate of 500 Hz. Of the children, 562 were female (47.4%) and 601 were male (52.6%). The total population was divided into ten age groups. Significant differences in normal limits were determined compared with previously published studies.
Conclusion: The observed differences in various electrocardiograms parameters could be related to biologic variability and to some technical details such as precordial electrode placement and visual checking of the records in addition to race.

Faculty of Dentistry, Ain Shams University, Cairo, Egypt.
Purpose: The purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.
Methods: 54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks.

Introduction: Nurses' job satisfaction in hospitals is fundamental for the quality of care and the safety of patients. However, sociodemographic trends require moving care to patients' homes, and the predictors of job satisfaction for nurses working in the home care settings remain largely unknown. Therefore, the aim of this study was to investigate job satisfaction of nurses working in Italian home care settings and its determinants.

Background: Conventional quantitative MRI (qMRI) scan is time-consuming and highly sensitive to movements, posing great challenges for quantitative images of individuals with involuntary movements, such as Huntington's disease (HD).
Purpose: To evaluate the potential of our developed ultra-fast qMRI technique, multiple overlapping-echo detachment (MOLED), in overcoming involuntary head motion and its capacity to quantitatively assess tissue changes in HD.
Study Type: Prospective.
