There is growing evidence that inflammatory processes of activated microglia could play an important role in the progression of nerve cell damage in neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease which harbor features of chronic microglial activation, though the precise mechanism is unknown. In this study, we presented in(More)
PURPOSE To evaluate the accuracy of transcranial Doppler (TCD) sonography using different criteria for predicting cerebral infarction due to symptomatic vasospasm. METHODS We retrospectively evaluated the clinical and radiologic data of consecutive patients admitted with acute aneurysmal subarachnoid hemorrhage (SAH) in the anterior cerebral circulation(More)
BACKGROUND AND PURPOSE This study aimed to identify predictors of acute mortality after intracerebral hemorrhage (ICH), including voxel-wise analysis of hematoma location. METHODS In 282 consecutive patients with acute ICH, clinical and radiological predictors of acute mortality were identified. Voxel-based lesion-symptom mapping examined spatial(More)
This paper presents a calibration method for a robot Head-Eye system which can be used in a humanoid robot vision system. This method estimates the transformation between the robot coordinate and the camera coordinate. The calibration procedure uses visual measurements and kinematic information as the inputs of nonlinear optimization. For this calibration(More)
Cognitive architectures provide infrastructure for modeling human cognition. Recent studies reveal that these architectures are useful control mechanisms for a variety of robots. Previously, we showed one such architecture, ICARUS, can successfully control a humanoid robot for Blocks World tasks in a simulated environment. In the current work, we extend the(More)
BACKGROUND Plasma B-type natriuretic peptide (BNP) is used as a diagnostic marker of cardiovascular diseases. BNP is secreted mainly from the myocardium and has been detected by immunoreactivity in brain and cerebral arteries. The aim of our study was to investigate plasma BNP in patients with acute cerebral infarction according to infarction subtype and(More)
BACKGROUND Posterior circulation (PC) stroke, which was previously less well known than anterior circulation (AC) stroke, has become more identified due to the development of imaging equipment. Recently, the initial stroke severity assessed by the NIH Stroke Scale (NIHSS) was reported as a useful measure for predicting the outcome of PC as well as AC(More)
Aspergillus tracheobronchitis (AT), an unusual form of invasive pulmonary aspergillosis (IPA), is characterized by pseudomembrane formation, ulcer or obstruction that is predominantly confined to tracheobronchial tree. Hematologic malignancies, neutropenia, solid organ transplantation, chronic corticosteroid therapy and acquired immunodeficiency syndrome(More)
OBJECTIVE This study analyzed the relationship between prognosis and multiple clinical factors of ruptured middle cerebral artery (MCA) aneurysm with intracerebral hemorrhage (ICH), to aid in predicting the results of surgical treatment. METHODS Enrolled subjects were 41 patients with ruptured MCA aneurysm with ICH who were treated with surgical clipping.(More)
