BACKGROUND The C242T polymorphisms of P22(phox) and plasma vitamin E have been associated with the risk of coronary heart disease (CHD) in several studies, but the results have been inconsistent. In this study, we sought to examine potential interactions between P22(phox) genotypes, plasma vitamin E concentrations, and smoking in relation to CHD risk. (More)
The breast cancer stem cells (BCSC) play important roles in breast cancer occurrence, recurrence and metastasis. However, the role of estrogen signaling, a signaling pathway important in development and progression of breast cancer, in regulation of BCSC has not been well established. Previously, we identified and cloned a variant of estrogen receptor α,(More)
Partially observable Markov decision process (POMDP) is an ideal framework for sequential decision-making under uncertainty in stochastic domains. However, it is notoriously computationally intractable to solving POMDP in real-time system. In order to address this problem, this paper proposes a point-based online value iteration (PBOVI) algorithm which(More)
BACKGROUND/PURPOSE The efficacy of cosmetics on human skin measured under normal mild laboratory environment might be discounted by exterior environment factors such as wind, UV exposure, etc. Few studies have focused on the 'genuine' efficacy of cosmetics on human skin during exposure to external rigorous environment. The aim of this study was to develop a(More)
Learning the enormous number of parameters is a challenging problem in model-based Bayesian reinforcement learning. In order to solve the problem, we propose a model-based factored Bayesian reinforcement learning (F-BRL) approach. F-BRL exploits a factored representation to describe states to reduce the number of parameters. Representing the conditional(More)
Based on the early transcriptome and digital differentially expressed profiling library construction in consecutive monoculture (two-year culturing) Rehmannia glutinosa, we screened and chose the twelve differentially expressed protein genes which might be related with calcium signal system. The spatiotemporal expression of these genes was measured by the(More)
OBJECTIVE To investigate the features of the multifocal electroretinogram (mfERG) first-order kernel P(1) wave in anisometropic amblyopic eyes. METHODS mfERG of fifteen anisometropic amblyopic eyes and their normal control eyes were recorded with ROLAND RETIscan visual evoked response system, the mean amplitude density and eclipse period of the P(1) wave(More)
OBJECTIVE To investigate the expression of endothelium tight junction protein Claudin-5 and intercellular adhesion molecule CD99 in solid-pseudopapillary neoplasms (SPN) and neuroendocrine tumors of pancreas (P-NET), and their significance in the differential diagnoses. METHODS Immunohistochemical staining of Claudin-5 and CD99 was performed in 37 cases(More)
OBJECTIVE In contrast to the newly-planted plants, through measuring and analyzing the chlorophyll content, photosynthetic characteristics, root activity and enzyme activity of Rehmannia glutinosa in growth stages, the differentiation manifestation of R. glutinosa physiological activity mediated by continuous cropping was studied. METHODS SPAD-502(More)
