BACKGROUND AND PURPOSE Telemedicine is emerging as a potential timesaving, efficient means for evaluating patients experiencing acute stroke. In areas where local stroke care specialists are not available, telemedicine can link an emergency department physician with a specialist in a stroke treatment center. This consultation provides an opportunity for administration of thrombolytic drugs with...

BACKGROUND AND PURPOSE Low rates of thrombolysis for ischemic stroke in China have mainly been attributed to delays in presentation to the hospital. This study aimed to evaluate factors associated with these delays. METHODS Data were from a prospective, multicenter, hospital-based registry of patients with acute stroke (ChinaQUEST [Quality Evaluation of Stroke Care and Treatment]), which invo...

Background: Endovascular therapy within an appropriate time has been shown to improve neurological outcomes in patients with ischemic stroke. A hybrid emergency room is unit that can be used for resuscitation, computed tomography (CT), surgery, and angiography. Therefore, immediate CT endovascular performed without transfer other rooms. We aimed evaluate the possibility of using a shorten strok...

background: stroke is a leading cause of death all around the world, and ischemic stroke is considered to be the most common stroke type. toll-like receptors (tlrs) are important molecules for detection of both pathogen invasion and tissue damage. in this regard, the purpose of this study was to assess the expression level of tlr2 on monocytes in patients with ischemic stroke and to evaluate th...

conclusions it seems that the incidence of different types of stroke-induced aphasia in ahvaz is influenced by the calendar-temporal changes. according to the findings, to prevent the occurrence of stroke-induced aphasia, necessary counseling should be provided for lifestyle changes. results according to the obtained results 39.9% of the studied patients had a stroke-induced aphasia. the highes...

oxygen therapy might increase damaged tissue oxygenation, turn on the aerobic pathway, and save neurons from death and could improve clinical outcome of the patients with stroke and head trauma. hyperbaric oxygen therapy is accompanied by some unfavorable effects. results of normobaric oxygen therapy on clinical outcomes of patients with stroke were controversial up till now.  this study was th...

BACKGROUND Acute stroke management emphasizes prompt recognition of symptoms and early medical attention. The effectiveness of stroke treatment is highly dependent on amount of time lapsed between onset of symptoms and treatment. In this study, factors that delayed seeking medical attention after stroke in southern Taiwan were explored. METHODS This was a prospective one-center study in which...

In this paper we propose a user interface for the design of 1D transfer functions. The user can select a feature of interest by drawing one or more strokes directly onto the volume rendering near its silhouette. Based on the stroke(s), our algorithm performs a histogram analysis in order to identify the desired feature in histogram space. Once the feature of interest has been identified, we aut...
