Truly fluorescent excitation-dependent carbon dots are prepared, and the relationship between their chemical composition and fluorescent emission is discussed. Furthermore, potential applications of the as-prepared carbon dots to multicolor bio-labeling and multidimodal sensing are demonstrated.
BACKGROUND The relationship between diet, lifestyle and cognition of old adults has been indicated in several population-based studies. However, the conclusions derived from these studies are inconsistent. METHODS A cross-sectional study was carried out in 894 old Chinese adults aged 50 and above. Cognitive function of the participants was measured by(More)
OBJECTIVE Published articles reported controversial results about the association of anxiety disorders with the risk of smoking behaviors. A meta-analysis was performed to assess this association between anxiety disorders and smoking behaviors. METHODS A comprehensive search was performed to identify prospective observational studies (from January, 1990(More)
PURPOSE Insufficient and excessive sleep duration have become increasingly common in modern society. Published literatures report controversial results about the association of sleep duration with coronary artery disease (CAD). METHODS A comprehensive search was performed to identify related prospective studies providing quantitative estimates between(More)
BACKGROUND AND OBJECTIVES Smoking and smoking cessation are both psychological and physiological traits. We aimed to investigate the interaction between dopamine pathway gene scores and nicotine dependence on smoking cessation in a rural Chinese male population. METHODS Participants were recruited from 17 villages in Shandong, China. DNA was extracted(More)
BACKGROUND The nicotine dependence (ND) has negative and smoking abstinence self-efficacy (SASE) has positive effects on successful smoking cessation, but scant data is now available for what is the mediating role of SASE on the relationship between ND and successful smoking cessation. The aim of this study was to assess the abovementioned mediation. (More)
AIMS A meta-analysis was performed to assess the association of hepatic cytochrome P450 2A6 (CYP2A6) gene polymorphisms with cigarette consumption. METHODS A comprehensive search was conducted to identify the studies of the above-mentioned association. The fixed effect model (FEM) or random effect model (REM) was selected based on the homogeneity test(More)
Recent studies have suggested that serum microRNAs (miRNAs) are novel biomarkers for many cardiovascular diseases, but their role in Kawasaki disease (KD) is still unclear. We demonstrated that serum miR-92a-3p levels were significantly higher in children with KD compared with children with fever and controls (both P < 0.05). When the disease recovered,(More)
BACKGROUND A recent study indicates that the incidence of smoking cessation varies with age. Although nicotine dependence (ND) has been regarded as one of the most significant barriers of successful smoking cessation, few researches have focused on the relationship between nicotine dependence and age. METHODS A cross-sectional study (conducted in 2013)(More)
In this paper, we investigate the high frequency performance of Co90Zr10/SiO2/Co90Zr10 trilayers. It is demonstrated that the in-plane isotropic microwave performance is theoretically derived from the solution of the Landau-Lifshitz-Gilbert equation and experimentally achieved in that sandwich structured film. The valuable isotropic behavior comes from the(More)
