Alzheimer's disease (AD), the most prevalent cause of dementia in the elderly, is characterized by progressive cognitive and intellectual deficits. Most patients with mild cognitive impairment (MCI) are thought to be in a very early stage of AD. Resting-state functional magnetic resonance imaging reflects spontaneous brain activities and/or the(More)
The marginal division (MrD) is a neostriatum subregion that links the limbic system and basal nucleus of Meynert; it is an important subcortical center that is involved in learning and memory. Alzheimer's disease (AD) is a neurodegenerative disorder and the most common cause of dementia in the elderly. AD clinically manifests as gradually progressive(More)
Specific patterns of brain atrophy may be helpful in the diagnosis of Alzheimer’s disease (AD). In the present study, we set out to evaluate the utility of grey-matter volume in the classification of AD and amnestic mild cognitive impairment (aMCI) compared to normal control (NC) individuals. Voxel-based morphometric analyses were performed on structural(More)
We develop a composite photoanode by sensitizing TiO2 nanorod arrays with PbS quantum dots (QDs) and CdS QDs. Benefitted from additional introduced PbS QDs and CdS QDs onto TiO2, the absorption of the composite photoanodes are broaden from UV to visible region. The experimental results showed that the PbS sandwiched between TiO2 and CdS cannot only broad(More)
OBJECTIVE To compare the clinical effects of three minimally invasive surgeries on the treatment of impacted upper ureteral calculi. METHODS 135 patients with impacted upper ureteral calculi were selected and randomly divided into three groups (Group A-C) (n=45), which were treated with transurethral ureteroscopic lithotripsy, minimally invasive(More)
The field effect transistors (FETs) exhibited ultrahigh responsivity (10 7 A/W) to infrared light with great improvement of mobility in graphene / PbS quantum dot (QD) hybrid. These reported transistors are either unipolar or depletion mode devices. In this paper, we presented and fabricated conveniently-controlled grapheme / PbS QD hybrid FETs. Through the(More)
