Platelets and von Willebrand factor (VWF) are recognized as important mediators of thrombosis at high shear rates, but their relative contributions are unclear. We employ a stenotic microfluidic test system to induce thrombus formation to occlusion on collagen at pathologic shear rates of 3500-6000 s-1. To obtain blood analogs with reduced platelet and VWF concentrations, human whole blood was ...

the aim of this study was to present and review retromandibular anteroparotid approach and to evaluate its efficacy and safety in reduction and fixation of subcondylar fractures. materials and methods : in the period between january 2013 to february 2014, 10 patients with the age range of 17 to 41 years with a diagnosis of subcondylar fracture at sina general hospital, iran, underwent open trea...

Introduction: Knowledge of the distribution of different malocclusions in a geographic location could help orthodontics better know the problems in that region. Moreover, giving awareness about the problem and treatment possibilities can help people. This study aimed to determine types of malocclusion and dental caries in children aged 11 to 14 years in Roudsar, Iran. Materials and Methods: In...

purpose: to investigate aqueous humor nitric oxide (no) levels in patients with branch retinal vein occlusion (brvo) and central retinal vein occlusion (crvo) and to compare these with age-matched controls. methods: eight consecutive patients with brvo and 16 patients with crvo were included in this study. aqueous humor specimens were obtained within 21 days of diagnosis. samples of aqueous hum...

BACKGROUND The present study aimed to determine and compare the anteroposterior position of the condyle in the mandibular fossa between groups of asymptomatic subjects with normal occlusion and asymptomatic subjects with Class I, Class II Division 1, and Class III malocclusions. MATERIAL AND METHODS Thirty persons with normal occlusion, 30 with Class I malocclusion, 30 with Class II Division ...

Regional cerebral blood flow was measured by the 133Xe inhalation technique in patients with unilateral carotid occlusion, unilateral carotid occlusion and contralateral carotid stenosis, bilateral carotid occlusion, or normal arteriograms. After adjusting for age, sex, and history of stroke, hemispheric blood flow asymmetry was shown to be a predictor of unilateral carotid occlusion with a sen...
