objective(s):the present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (uco) on the dorsal hippocampal neurons in rats. materials and methods:sixty four male sprague-dawley rats aged 4 months were divided into two groups of sham and uco. these two groups were further divided into 4 sets of histopath...

Abstract Ameloblastic fibroma is a relatively rare benign odontogenic tumor with two neoplastic components both epithelial and ectomesenchymal. A 10-year-old girl was referred to a dentist for routine dental treatments for evaluation of the distance between mandibular right first permanent molar and mandibular right second deciduous molar and it was associated with an undesirable backward mov...

Tooth agenesis is one of the most common congenital anomalies seen in humans. Although absence of one or more teeth is common but absence of multiple teeth is rare. Oligodontia is a rare developmental anomaly, involving agenesis of six or more permanent teeth, excluding the third molars. The reported prevalence of oligodontia in permanent dentition is 0.14%. Oligodontia can present as an isolat...

background: permanent pacemakers provide effective relief of symptoms and are life-saving in patients with symptomatic heart block. implantable cardioverter defibrillators (icd) are also increasingly recognized as life-saving tools in various groups of patients with malignant ventricular tachyarrhythmias. methods: as part of the “world survey on pacemaker and icd implantations”, a survey of all...

In the search for a more reproducible focal ischemic stroke model in the rat, we systematically interrupted blood flow to the right middle cerebral artery territory by ligating the right middle cerebral artery, and the right and left common carotid arteries in succession. Using a laser-Doppler flowmeter, we found that the relative surface blood flow in cerebral cortex supplied by the right midd...
