A novel cell-targeting, near-infrared light-responsive drug delivery platform based on mesoporous silica-coated gold nanorods that are surface-functionalized with aptamer DNA is constructed. Aptamer DNA is used as both capping and targeting agent. In vitro studies show the feasibility of using this nanocarrier for targeted and noninvasive remote controlled(More)
INTRODUCTION Vestibular illusions are the most common illusions that can cause spatial disorientation in flight. This study aims to find out whether and how the ability of keeping arm-hand posture is affected by the vestibular illusions induced by galvanic vestibular stimulation (GVS). METHODS With their heads and trunks firmly fixed, 16 subjects(More)
Previous neuroimaging studies have suggested that cerebral changes over normal aging are not simply characterized by regional alterations, but rather by the reorganization of cortical connectivity patterns. The investigation of structural covariance networks (SCNs) using voxel-based morphometry is an advanced approach to examining the pattern of covariance(More)
Galvanic vestibular stimulation (GVS) can be used to study the body's response to vestibular stimuli. This study aimed to investigate whether postural responses to GVS were different between pilots and the general populace. Bilateral bipolar GVS was applied with a constant-current profile to 12 pilots and 12 control subjects via two electrodes placed over(More)
It has been widely observed that atherosclerotic stenosis occurs at sites with complex hemodynamics, such as arteries with high curvature or bifurcations. These regions usually have very low or highly oscillatory wall shear stress (WSS). In the present study, 3D sinusoidally pulsatile blood flow through the models of internal carotid artery (ICA) with(More)
A new type of rapid, highly sensitive, and selective fluorescence turn-on assay for detection of cysteine and histidine using a DNA/ligand/ion ensemble is developed. This assay is based on the highly specific interaction between the amino acids and the metal ions and the strong fluorescence thiazole orange (TO)/DNA probe in a competition assay format. The(More)
It has been proposed that a mass transfer phenomenon called concentration polarization of low-density lipoproteins (LDLs) may occur in the arterial system and is likely involved in the localization of atherogenesis. To test the hypothesis that concentration polarization of LDL may be suppressed by the helical flow pattern in the human aorta, hence sparing(More)
Equinus, varus, cavus, and adduction are typical signs of congenital talipes equinovarus (CTEV). Forefoot adduction remains a difficulty from using previous corrective methods. This study aims to develop a corrective method to reduce the severity of forefoot adduction of CTEV children with moderate deformities during their walking age. The devised method(More)
Fetal head molding is important for adapting the fetal head to the birth canal during vaginal delivery; however, excessive deformation of fetal head may lead to severe complications. Although labor force is one of the major factors which cause deformation of the fetal head, its effect on fetal head molding has not been quantitatively investigated yet. We(More)
BACKGROUND Most studies that attempt to clarify structural abnormalities related to functional disconnection in patients with Alzheimer's disease (AD) have focused on exploring pathological changes in cortical gray matter. However, white matter fibers connecting these cerebral areas may also be abnormal. PURPOSE To investigate the regional changes of(More)
