Since Darwin's seminal works, the universality of facial expressions of emotion has remained one of the longest standing debates in the biological and social sciences. Briefly stated, the universality hypothesis claims that all humans communicate six basic internal emotional states (happy, surprise, fear, disgust, anger, and sad) using the same facial(More)
Brain-derived neurotrophic factor (BDNF) and its receptor, tropomyosin-related kinase receptor B (TrkB), play a critical role in activity-dependent plasticity processes such as long-term potentiation, learning, and memory. It has been shown that BDNF exerts different or even opposite effects on behavior depending on the neural circuit. However, the detailed(More)
Brain-derived neurotrophic factor (BDNF) has been reported to play important roles in the modulation of anxiety, mood stabilizers, and pathophysiology of affective disorders. Recently, a single nucleotide polymorphism (SNP) in the BDNF gene (Val66Met) has been found to be associated with depression and anxiety disorders. The humanized BDNF(Met/Met) knock-in(More)
OBJECTIVES Our purpose was to determine whether the common polymorphisms (SNP-604, SNP1192, and SNP1719) in KDR are associated with risk of coronary heart disease. BACKGROUND Vascular endothelial growth factor (VEGF) and its receptor KDR (kinase insert domain-containing receptor/fetal liver kinase-1, also called VEGFR2) play critical roles in angiogenesis(More)
Microcystins are a family of cyclic peptides that are potent inhibitors of the protein phosphatase families PP1 and PP2A. Only three human proteins are thought to be able to mediate the hepatic uptake of microcystins (the organic anion-transporting polypeptides OATP1B1, OATP1B3, and OATP1A2), and the predominant hepatic expression of these transporters(More)
OBJECTIVE Experimental and clinical data suggested that brain-derived neurotrophic factor (BDNF) plays an important role in the pathogenesis of Alzheimer's disease (AD). Amnestic mild cognitive impairment (aMCI) is characterized by declined cognitive function and has a high probability of evolving into AD. The aim of this study was to investigate serum BDNF(More)
Brain-derived neurotrophic factor (BDNF) plays important roles in cell survival, neural plasticity, learning, and stress regulation. However, whether the recently found human BDNF Val66Met (BDNF(Met)) polymorphism could alter stress vulnerability remains controversial. More importantly, the molecular and structural mechanisms underlying the interaction(More)
Alzheimer's disease (AD) can be conceptualized as a disconnection syndrome. Both remitted geriatric depression (RGD) and amnestic mild cognitive impairment (aMCI) are associated with a high risk for developing AD. However, little is known about the similarities and differences in the topological patterns of white matter (WM) structural networks between RGD(More)
OBJECTIVE To investigate regional activity abnormalities of first-episode remitted geriatric depression (RGD) using a resting-state functional magnetic resonance imaging (fMRI) in closely matched patients and healthy controls, and to examine the relationship between performances on neuropsychological tests and regional activity abnormalities. METHOD A(More)
In this paper, we adopt local Fourier transform as a texture representation scheme and derive eight characteristic maps for describing different aspects of co-occurrence relations of image pixels in each channel of the (SVcosH, SVsinH, V) color space. Then we calculate the first and second moments of these maps as a representation of the natural color image(More)
