Comparison of Serum Selenium Levels Between Patients with Newly Diagnosed Atrial Fibrillation and Normal Controls
Biol Trace Elem Res. 2022 May 9. doi: 10.1007/s12011-022-03281-9. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common sustained dysrhythmia in the elderly population. It is estimated to affect more than 30 million people worldwide. AF occurs when abnormal electrical impulses start to activate in the atria and override the heart's natural pacemaker, which can no longer control the heart's rhythm. Since atrial contractility is impaired in AF, blood flow in the atria becomes stasis over time and causes thrombus formation. This thrombus causes the risk of embolism and causes complications such as stroke. ...

Effects of Combined Sertraline and Magnesium in Rat Atrium
The objective of this study is to determine the synergistic effects of an antioxidant ion Mg+2, combined with selective serotonin reuptake inhibitor sertraline, in treatment or prevention of major depression and regulation of inotropic effect in the early postoperative period. Adult male 40 Wistar albino rats were randomly divided into 6 groups. Three to 4-mm long atrium strips were placed in organ bath, tension was adjusted to 2 g. Isometric contractions were induced with 10-3 M adrenaline. Group 1 was the control group, cumulative sertraline was given to group 2, cumulative MgSO4 to group 3, combined cumulative sertralin...
