Introduction: Biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. The results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...
Abstract Glasses from two varieties of (LiF-B 2 O 3 ) and (LiF-P 5 systems with equal 50 mol % for each partner together samples doped 1 or 2% Bi were synthesized by melting–annealing mechanism. Multiple optical, FTIR photoluminescence spectral measurements carried out. Optical spectra —doped glasses exhibit UV-near visible peaks owing to the specific absorption 3+ ions. elucidate presence char...
Associations between Vitamin D Levels and Risk of Anterior Cruciate Ligament Injury in Male Athletes
Background and purpose: Association between vitamin D and anterior cruciate ligament injury (ACLI) in male athletes is poorly understood, and current data are not sufficient and consistent. The present study investigated the association between vitamin D and ACLI in some Iranian male athletes. Materials and methods: This cross-sectional study was carried out in 100 male athletes with knee pain...
