TL;DR: This is the first study to use PSG to evaluate sleep problems both in ET and PD patients and point out different sleep problems in these two common movement disorders which should be investigated in further studies.
Abstract: Objective:Sleep problems are a common non-motor complication of Parkinson disease (PD), and patients with essential tremor (ET) share a number of motor and non-motor features of PD. To clarify the ...

TL;DR: It is suggested that TQ confers protection against myocardial I/R injury and suppresses reperfusion-induced arrhythmias.
Abstract: Reperfusion of the ischemic myocardium causes the myocardial injury and life-threatening ventricular arrhythmias in human. This study aimed to investigate the effects of thymoquinone (TQ) on myocardial ischemia/reperfusion (I/R) injury and ischemia- and reperfusion-induced ventricular arrhythmias in anaesthetized rats. Adult male Wistar albino rats were divided into two groups, each containing a control and TQ-treated subgroups. In group I, the myocardial infarct size was determined by triphenyl tetrazolium chloride staining following 2-h reperfusion preceded by 30 min of ischemia. In group II, a 6-min myocardial ischemia was followed by a 10-min reperfusion. TQ-treated subgroups were treated with TQ (10 mg/100 μl/kg, i.p.) and the control subgroups were treated with the vehicle (100 μl/kg, i.p.) 20 min prior to the ischemic period. Ischemia was induced by ligating the left main coronary artery, followed by reperfusion. TQ treatment reduced the infarct size (15 ± 4% versus 69 ± 6%, P<0.01). Pretreatment with TQ decreased arrhythmia scores, as well as the incidence of ventricular tachycardia and the incidence of ventricular fibrillation during the reperfusion period (arrhythmia scores: 1.4 ± 0.3 versus 4.4 ± 0.3, P<0.01). These results suggest that TQ confers protection against myocardial I/R injury and suppresses reperfusion-induced arrhythmias.
