Are b...

purpose: to determine the correlation between hand dominancy and eye dominancy with visual acuity and refraction in subjects with refractive errors. methods: this cross-sectional study includes 620 patients undergoing lasik. their refractive error (dry and cycloplegic), hand dominancy, eye dominancy (by hole-in-the-hand method) and visual acuity were determined. exclusion criteria were monocula...

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important.

There is ongoing discussion whether cellular or mobile phone has any effects on brain. The aim of this research is to investigate the effects of mobile phone use on left and right ear using electroencephalograph (EEG). The brain waves are analyzed using Wavelet transform and Fast Fourier Transform. Twenty subjects are studied after recording their EEG signals using International 10/20 system of...
