A modified "cross-modal delayed response" paradigm was used to investigate putative processing of face expression in the absence of focused attention to the face. Neutral, happy and sad faces were presented during intervals occurring between a tone and a response imperative signal (a faint click), while subjects were instructed to discriminate the location(More)
AIM Autopsy evidence suggests that the presence of both Alzheimer(')s disease (AD) and cerebral infarction pathology is associated with more severe cognitive impairment than that produced by AD pathology alone. This study aims to investigate the effect of cerebral ischemia on cognitive function in rats with AD constructed by hippocampal injection and to(More)
Our results indicate that overexpression of the GhWRKY39 - 1 gene enhances resistance to pathogen infection and tolerance to high salt and oxidative stress in transgenic Nicotiana benthamiana. WRKY transcription factor genes play significant roles in the response to biotic and abiotic stresses. Cotton (Gossypium hirsutum) is an important fiber and oil crop(More)
Papillomavirus E2 is a multifunctional viral protein that regulates many aspects of the viral life cycle including viral episome maintenance, transcriptional activation, and repression. E2 is degraded by the ubiquitin-proteasome pathway. Cellular bromodomain protein Brd4 has been implicated in the stabilization of the E2 protein. E2 normally shuttles(More)
Nicotine was reported to reduce the plaque burden and could be used as a possible anti-Alzheimer's disease agent. However, the effect of nicotine on memory and tau pathology in Alzheimer's disease has been less studied. The present study investigated the effect of nicotine on tau phosphorylation and cognitive impairment induced by hippocampus injections of(More)
Alzheimer's disease (AD) is characterized by the degeneration of basal forebrain cholinergic neurons, whose survival and function are affected by neurotrophins and their receptors. The impaired signaling pathway of brain-derived neurotrophic factor/tropomyosin-related kinase B (BDNF/TrkB) is considered to play an important role in AD pathogenesis. To(More)
Insufficient neurotrophic support increases the risk for developing Alzheimer’s disease (AD). Mounting evidence has confirmed the association of brain-derived neurotrophic factor (BDNF) and apolipoprotein E (ApoE) with AD. As both BDNF and ApoE are suggested to be involved in modulating brain integrity, the present study is aiming to investigate the(More)
OBJECTIVE To assess the impact of intracranial arterial stenosis on the progression from mild cognitive impairment (MCI) to Alzheimer disease (AD). METHODS A total of 423 participants with MCI were included and evaluated with clinical and neuropsychological examinations annually for 4 years. The incidence of dementia due to AD was investigated. CT(More)
Spinal cord injury (SCI) is a serious clinical situation without any effective therapy to date. Traumatic SCI triggers a complex pathological process including inflammatory response and glial scar formation. In this study, we demonstrated that curcumin, a natural product which functions as an anti-inflammatory agent, inhibited the activation of signal(More)
