Apolipoprotein-E4 (APOE-E4) is a major genetic risk factor for developing Alzheimer's disease (AD). The verbal fluency task (VFT), especially the subtask category fluency, has shown to provide a good discrimination between cognitively normal controls and subjects with AD. Interestingly, APOE-E4 seems to have no effect on the behavioral performance during a VFT in healthy elderly. Thus, the purp...
BACKGROUND We have explored the potential prefrontal hemodynamic biomarkers to characterize subjects with Traumatic Brain Injury (TBI) by employing the multivariate machine learning approach and introducing a novel task-related hemodynamic response detection followed by a heuristic search for optimum set of hemodynamic features. To achieve this goal, the hemodynamic response from a group of 31 ...
Anterior cingulate cortex has been functionally linked to the detection of outcomes that are worse than expected using both scalp electrophysiological [event-related potential (ERP)] and hemodynamic [functional MRI (fMRI)] responses. This study used a reward prediction violation design which acquired both ERP and fMRI data from the same participants in different sessions. Both the medial fronta...
ABSTRACT Electroconvulsive therapy (ECT) has been used widely to treat psychiatric disease. ECT under anesthesia is associated with hypertension and tachycardia. The cardiovascular effects of ECT were studied after per-treatment of 100 patients with lidocaine 1.5 mg/Kg (experimental group) and saline solution (control), using a double-blind, randomized clinical trial study. There were no sign...
conclusions both anesthetic regimens were acceptable for induction in patients with coronary artery disease and left ventricular dysfunction undergoing coronary artery bypass graft surgery. results incidence of pain on injection (2 - 4%) and myoclonus (10%) was less in both groups. the hemodynamic response was similar in the two groups for all variables over the time interval, except for ci at ...
The objective of this study was to determine whether endogenous IL-10 is capable of regulating hemodynamic parameters, leukocyte recruitment, and microvascular permeability in response to endotoxin. Intravital microscopy was used to examine hemodynamic parameters, leukocyte rolling and adhesion, and microvascular permeability in cremasteric postcapillary venules in wild-type mice and in IL-10-d...
background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...
