In all medical centers electrocardiography is one of the first steps in the evaluation of patients suspected of heart disease. It is therefore clear that distinguishing normal from pathologic patterns in electrocardiography is of utmost importance. The aim of this descriptive and analytical study was to determine the normal electrocardiographic indices in all leads and to investigate the influe...

We improve the class of indices for which normality takes place in a Nikishin system and apply this in Hermite-Padé approximation of such systems of functions.

BACKGROUND Interpreting the erythroid lineage in populations with high frequency of α+ thalassemia allele is challenging due to the high prevalence of α+ thalassemia homozygotes. For such populations, separate reference values for normal and α+ thalassemia homozygotes are needed. METHODS We studied the erythroid lineage in 1,079 citizens of United Arab Emirates (UAE). Subjects with abnormal h...

Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio in the first second (FEV1% VC), forced expiratory flow between 200 and 1200 ml (FEF200-1200), and forced mid expiratory flow between 25% and 75% of FVC (FMF) were measured in 275 Libyan men ranging from 20 to 60 years. All values were lower with increasing age and, apart from FEV1% VC, were posit...
