arrhythmogenic right ventricular dysplasia/cardiomyopathy (arvd/c) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (rv) dysfunction, accounting for 20% of sudden cardiac deaths. characterized by the fibro-fatty infiltration of the rv free wall, arvd/c presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular...

purpose : to report a case of congenital macular macrovessels case report : an 8-year-old girl was referred for decreased vision in her right eye. her best corrected visual acuity (bcva) in the right eye was 20/200 and in the left eye 20/20. anterior segment examinations were normal in both eyes. posterior segment examination of the right eye showed abnormal macrovessels crossing the macula and...

We studied the significance of new blood vessels in the pathogenesis of temporomandibular joint osteoarthritis (TMJOA). Fifteen 8-week-old female Sprague-Dawley rats were selected to establish TMJOA models of gradually induced occlusal disorders. Five rats were sacrificed at 4, 8 and 16 weeks, and histological exam was conducted along with micro-computed tomography observation on the condyle sp...

Glioma growth depends on microvascular adaptation and angiogenesis. Our study focused on the structural changes that occur in the microvasculature to adapt to glioma growth. Vascular morphology, morphometry and permeability studies were performed in induced rat gliomas. Tumours were identified by magnetic resonance imaging and histopathology. Blood brain barrier integrity was examined by EBA an...

background: differences in the quantity and distribution of coronary veins between patients with ischemic and non-ischemic cardiomyopathy might affect the potential for the left ventricular (lv) lead targeting in patients undergoing cardiac resynchronization therapy (crt). in the current study, we assessed and compared the suitability of the coronary venous system for the lv lead placement in i...
