The coronary slow flow phenomenon is an angiographic finding characterized by delayed distal vessel opacification in the absence of significant epicardial disease, and important clinical entity because it may be cause angina at rest or during exercise, acute myocardial infarction, hypertension. pathophysiological mechanisms remain undetermined. Endothelial dysfunction microvascular have been suggested as underlying mechanisms. (SCF) considered to a form early phase atherosclerosis some...

OBJECTIVE: This study was conducted to understand whether the retrograde popliteal approach is safe and effective in cases where antegrade approaches, which are frequently used femoropopliteal stenosis, cannot be performed. MATERIAL AND METHODS: Between September 2020 2022, 89 patients with chronic totally occluded peripheral artery disease who underwent recanalization distal intervention were studied. All punctures performed patient prone position made just above knee joint. atherectomy...

During the preparation of beer wort, significant amounts waste raw materials, such as brewers’ spent grain (BSG), are generated. In line with zero-waste approach, a processing technology for BSG was developed to valorize this by-product. The method involves obtaining extract (plant-based milk), followed by filtration remove insoluble residues and subsequent fermentation produce vegan BSG-based yogurt-like products, without addition sucrose, well pectin, guar gum, konjac gum stabilizers....

Background: Left atrial (LA) deformation analysis by two-dimensional speckle tracking echocardiography (2D-STE) has recently been proposed as an alternative approach for estimating left ventricular (LV) filling pressure and dysfunction. Aim: To assess the LA myocardial function using 2D-STE in end-stage renal disease (ESRD) patients with preserved LV ejection fraction (PLVEF) to evaluate relationship of obtained results echocardiographically estimated pulmonary capillary wedge (ePCWP)....

It is well known that cardiovascular morbidity and mortality are high in diabetic patients. Cardiac involvement silent early these patients generally complain of chronic fatigue. This study was designed to evaluate the relation between glycemic control exercise capacity 330 who have no cardiac symptoms by sustaining dynamic exercise. After a examination, with coronary heart disease, ECG abnormalities, failure, valvular cerebrovascular peripheral artery anaemia neuropathy were excluded....

Abstract This study analyzes the effects of transaction costs on size hazelnut farms in Turkey. The finds that higher land slope and variance rain, as transaction‐cost‐increasing natural effects, lead to smaller holdings. High weather variation can increase monitoring laborers, make moving inputs or output up down harder, limit use machinery, reduce contractual performance labor contracts. For farm production functions, is a complex input with measurable interactions nature. Contrary common...

Objective It is known that patients with end-stage renal disease (ESRD) more frequently develop a wide range of left ventricular (LV) structural and functional abnormalities. The aim our study to evaluate the regional function using two-dimensional speckle tracking echocardiography (2D-STE) in ESRD preserved ejection fraction (PLVEF) undergoing haemodialysis treatment.Methods results In total 61 healthy individuals 87 were enrolled. Using 2D-STE method, strain (S) rate (SRS: systolic, SRE:...

Atherosclerotic coronary artery disease is the leading cause of death worldwide. Oxidative stress one key elements in pathogenesis atherosclerosis. Isoprostanes are established markers oxidative stress. The aim this study was to investigate association urinary 8-isoprostane levels with presence and severity (CAD) assessed by a validated scoring system.Urinary were measured 100 consecutive patients scheduled for angiography. Extent CAD modified Gensini scores.In CAD, higher (P < 0.001) than...

No-reflow phenomenon is the absence of myocardial perfusion despite adequate dilatation infarct related coronary artery during percutaneous intervention. It predicts severe left ventricular dysfunction and poor prognosis in acute in-farction (AMI). The present case a 54 year old Turkish female who presented with chest pain that had started 2.5 hours earlier. clinical laboratory findings were consistent AMI angiogram performed for primary angioplasty revealed 95% thrombotic occlusion TIMI...
