The full static picture of Li storage in Li(4)Ti(5)O(12) is derived using the latest spherical aberration-corrected scanning transmission electron microscopy and first-principles calculations. The accommodation of the additional Li(+) is directly visualized and the distribution of electrons introduced by lithium insertion deduced. Moreover, Li(4)Ti(5)O(12)(More)
OBJECTIVE To study the influence of mutation of 677 C to T in the methylenetetrahydrofolate reductase (MTHFR) gene on the plasma total homocysteine (tHcy) levels in hemodialysis patients. METHODS The study population included 40 healthy subjects and 53 patients with end-stage renal disease (ESRD) undergoing hemodialysis. C 677 T transition in the MTHFR(More)
Green space plays an important role in complex urban ecosystems and provides significant ecosystem services with environmental, aesthetic, recreational and economic benefits. Beijing is the capital city of China and has a large population of about 15.81 million. Construction of green spaces is an important part of sustainable development in Beijing. To(More)
Farnesoid X receptor (FXR) is a nuclear hormone receptor involved in bile acid synthesis and homeostasis. Dysfunction of FXR is involved in cholestasis and atherosclerosis. FXR is prevalent in liver, gallbladder, and intestine, but it is not yet clear whether it modulates neurobehavior. In the current study, we tested the hypothesis that mouse FXR(More)
The 364 nm photoelectron spectrum of Si2C3 2 is reported, together with high level ab initio calculations of the linear anion, and six linear and eight nonlinear structures of the neutral Si2C3 . The adiabatic electron affinity of Si2C3 , corresponding to the transition from the linear anion to the lowest electronic state of the linear singlet neutral, is(More)
The current multidisciplinary treatment for patients with high-risk neuroblastoma (NB) is the common census. However, protocols and opinions are different in different regions and institutions. We aimed to assess the protocol formulated by Chinese Children's Cancer Group study in 2009, and the impact of surgery extent was highlightly evaluated. METHODS(More)
Direct observation of delithiated structures of LiCoO(2) at atomic scale has been achieved using spherical aberration-corrected scanning transmission electron microscopy (STEM) with high-angle annular-dark-field (HAADF) and annular-bright-field (ABF) techniques. The ordered Li, Co, and O columns for LiCoO(2) nanoparticles are clearly identified in ABF(More)
OBJECTIVE To preliminarily investigate the expression and clinical significance of leptin and adiponectin in esophageal squamous cell carcinoma (ESCC). METHODS The expression of leptin and adiponectin in ESCC and normal esophageal mucosal tissue was detected by immunohistochemical staining with tissue microarray. The correlation between leptin,(More)
After decades of efforts, the research on resistance switching (RS) behavior in transition metal oxides has shifted to the stage of verifying the proposed models by direct experimental evidences. In this paper, RS behavior and oxygen content variation of La0.85Sr0.15TiO3/SrTiO3:Nb (LSTO/STON) were investigated by in situ transmission electron microscopy(More)
Multispectral image compression which are based on the one-,two- and three-dimensional wavelet transforms has been existed in many papers. Existing image compression algorithms have proved to be very efficient in compressing these kinds of images.We adopted the principal component analysis,clustering and spectral angle cosine to classify and compress in(More)
