To evaluate the acute effect of lovastatin on diabetic endothelial dysfunction, we examined this effect on the aortic rings of streptozotocin-diabetic rats. The endothelial function was assessed in aortic rings isolated from diabetic rats, 12 weeks after treatment with streptozotocin (45 mg/kg, i.p.). The concentration-response curve to acetylcholine (Ach) in the aortic rings precontracted with...

introduction: the persian squirrel (sciurus anomalus) is the only member of the sciuridae family found in the middle east. some people maintain them as pets, thus their referrals to veterinary hospitals has been increased recently. several morphological studies have been carried out mainly on the arch of aorta and its branches in common rodents, small mammals, and domestic animals but there are...

Objective(s): Atherosclerosis is a chronic immune-inflammatory disease that generally leads to ischemic heart disease. Ghrelin has several modulatory effects on cardiovascular system. In this study, we investigated the effect of ghrelin on aortic intima-media thickness, size and the number of adipocyte cells in obese and control mice. Materials and Methods:This study was conducted on 24 male C...

objectives to evaluate morphologic variations at the aortic isthmus with particular attention to ductus diverticulum, a mimicker of traumatic pseudoaneurysm, and to describe differences using computed tomography (ct) images. patients and methods from december 2013 to december 2014, patients who underwent a chest ct examination after blunt trauma at our emergency department were included. aortic...

acute aortic dissection (aad) is the most frequent catastrophic event of the aorta; it occurs nearly three times as frequently as the rupture of abdominal aortic aneurysm . sixty percent of dissection cases are classified as proximal or type a and 40% as distal or type b, according to the stanford classification. the most frequent causes of death in acute type b dissection are aortic rupture an...

aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. this fatal disorder is hard to diagnose, especially in young patients. we present the case of aortic dissection in a 15-year-old boy referred to the emergency department of yazd university of medical sciences in november 2015. the patient presented to our department with sudden acute c...

conclusions with the increase in interventional procedures in cardiology, iatrogenic pathology of the aorta is seen more frequently, and every cardiologist should know how to diagnose and treat this group of diseases. evidence acquisition our search strategy involved an investigation in the pubmed database for every available article in peer reviewed journals between 1975 and 2015, for subjects...
