Atrial fibrillation (AF) is associated with oxidative stress and inflammation. Paraoxonase-1 (PON1), circulates in blood bound to high-density lipoproteins and reduces systemic oxidative stress. The aim of this study was to evaluate PON1 serum concentration and PON1 arylesterase activity (AREase) in patients with AF.

- A 73-year-old woman experienced recurrent headaches and dizziness, leading to a referral to a cardiology department due to suspected significant stenosis in her left internal carotid artery, along with a past history of hypertension.
- After normal neurological exams and lab tests, a neck vascular ultrasound revealed a low bifurcation in the left common carotid artery and a hypoplastic left internal carotid artery with a sinuous path.
- A CT angiography confirmed these findings, showing an unusual anatomy of the left common carotid artery and revealed that the left vertebral artery originated directly from the aortic arch with a kinking trajectory.
Differences in life histories are commonly exhibited within ecological communities, especially among species that display increased variations in body size and morphology and are phylogenetically distant. To examine the relationship between morphological dissimilarity and life history divergence, we investigated three morphologically distinct and distantly related species of freshwater amphipods that co-occur throughout the Danube lowlands - Gammarus balcanicus dacicus, Niphargus valachicus and Synurella ambulans - by collecting monthly samples during a one-year period. Results revealed that the studied species differ significantly with respect to fecundity, size at maturity, number of generations per year, duration and timing of the reproductive period and egg volume.
