Greek-Turkish boundary near the cities Kos and Bodrum has been shaken on July 20, 2017 by a Mw6.6 earthquake. The mainshock is located offshore did not generate an on-land surface rupture. Analyzing pre- post-earthquake continuous/survey-type static GPS observations, we investigated co-seismic displacements at 20 sites to characterize source parameters slip-distribution of mainshock. Fault plane solutions as well slip distribution have acquired through inversion modeling event elastic...

Background Free radical-mediated oxidative stress has been implicated in the etiopathogenesis of several disorders. The aim this study was to elucidate effect treatment with nebivolol on metabolic state stress, and antioxidant status markers patients cardiac syndrome-X (CSX), additionally, compare metoprolol treatment. Methods Thirty patients, 17 female 13 male, CSX were enrolled study. Nebivolol (5 mg/day) or (50 administrated for 12 weeks. Twelve hour fasting blood samples, taken at...

Many studies have shown that bilirubin may protect against atherosclerosis. In the present study, we assess association between serum total levels and severity of coronary artery disease (CAD) assessed by angiography Syntax score.Patients from our center, who visited center for a angiography, January 2008 to 2011, were eligible this analysis. Serum other blood parameters in at least 12-h fasting states determined. The patients divided into tertiles according their score.A 299 registered...

Abstract Atrial fibrillation (AF) is the most common arrhythmia in clinical practice and a major cause of morbidity mortality. The upregulation TRP channels believed to mediate progression electrical remodelling arrhythmogenesis diseased heart. However, there limited data about contribution development AF. aim this study was investigate leukocyte gene expressions non-valvular atrial (NVAF) patients. included 47 NVAF patients sex age matched controls. mRNA extracted from blood samples,...

The purpose of this study is to determine deformations in landslide areas with two methods, Persistent Scatterer Interferometry (PSI) and GNSS (Global Navigation Satellite System). In the Koyulhisar area, 53 points were established throughout region. Velocity values for these are three-dimensional. addition, TerraSAR-X SAR (Synthetic Aperture Radar) images processed Stanford Method Scatterers software. Slip surfaces region direction line sight calculated from PSI addition one-dimensional...

Mean platelet volume (MPV) is an indicator of activation, which a central process in the pathophysiology coronary heart disease. Metabolic syndrome (MS) may lead to worsened left ventricular systolic function by causing recurrent thrombotic events and aggravating systemic inflammation course acute myocardial infarction. The present study was designed investigate relationship between MPV patients with metabolic who had first ST-elevation infarction.MPV measured on admission 33 preserved...

Objective Ischemia/reperfusion (I/R) injury is an important cause of myocardial damage by means oxidative, inflammatory, and apoptotic mechanisms. The aim the present study was to examine potential cardio protective effects levosimendan in a diabetic rat model I/R injury. Methods A total 18 streptozotocin-induced Wistar Albino rats (55 mg/kg) were randomly divided into three equal groups as follows: group (DIR) which induced following left thoracotomy, ligating anterior descending coronary...

In the actively deforming region of western Anatolia, crustal deformation is accommodated by destructive earthquakes and a variety aseismic events. this study, we investigated 2016–2017 sequence located in Bolvadin Fault, one segments Akşehir-Simav Fault System Anatolia analysing surface derived from detailed geological mapping. Our findings suggest that episodes. During field studies area, progressive deformations, such as faults earth fissures with length 800 meters to 3 kilometres strike...

The prevalence of coronary artery anomalies (CAA) are reported between 0.6-1.3% in the literature. CAA usually asymptomatic incidental findings, but they may deteriorate circulation, cause symptoms and lead to sudden cardiac death; especially young athletes. Since interventional procedures increasing rapidly for treatment disease (CAD) modern era, comprehensive understanding is becoming progressively critical element dealing with CAD.We reviewed database Cardiac Catheterisation Laboratory...

In this study, the effect of height difference, geometry, and number GCPs on positional accuracy point cloud was investigated in UAV photogrammetry. It has been determined that topographic change study area, geometric structure GCPs, distance between are most important factors GCP network design. observed design is more than Photogrammetry method to increase accuracy.
