The European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines recommend the Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) to identify malnutrition risk in patients with liver disease. However, little is known about the application of the RFH-NPT to screen for the risk of malnutrition in China, where patients primarily suffer from hepatitis virus-related cirrhosis. A total of 155 cirrhosis patients without liver cancer or uncontrolled co-morbid illness were enrolled in this prospective study. We administered the Nutritional Risk Screening 2002 (NRS-2002), RFH-NPT, Malnutrition Universal Screening Tool (MUST) and Liver Disease Undernutrition Screening Tool (LDUST) to the patients within 24 h after admission and performed follow-up observations for 1·5 years. The RFH-NPT and NRS-2002 had higher sensitivities (64·8 and 52·4 %) and specificities (60 and 70 %) than the other tools with regard to screening for malnutrition risk in cirrhotic patients. The prevalence of nutritional risk was higher under the use of the RFH-NPT against the NRS-2002 (63 v. 51 %). The RFH-NPT tended more easily to detect malnutrition risk in patients with advanced Child–Pugh classes (B and C) and lower Model for End-stage Liver Disease scores (<15) compared with NRS-2002. RFH-NPT score was an independent predictive factor for mortality. Patients identified as being at high malnutrition risk with the RFH-NPT had a higher mortality rate than those at low risk; the same result was not obtained with the NRS-2002. Therefore, we suggest that using the RFH-NPT improves the ability of clinicians to predict malnutrition risk in patients with cirrhosis primarily caused by hepatitis virus infection at an earlier stage.
Current available methods to detect cow milk adulteration or accidental contamination of goat milk are both laborious and time consuming. The aim of this technical research communication was to develop a simple, rapid, specific and sensitive method for quantitative detection of cow milk in goat milk. A competitive lateral flow immunoassay (LFIA) strip was developed using a specific monoclonal antibody (mAb) labeled with colloidal gold nanoparticles (GNPs) for specifically binding to cow milk casein. The detection limit of this rapid detection was 0.07% of cow milk in goat milk, providing equal specificity and higher sensitivity when compared with a commercial enzyme-linked immunosorbent assay (ELISA). These result suggest that the established rapid GNPs-LFIA strip could be used for monitoring cow milk adulteration/contamination of goat milk.
Turnover intention is a negative outcome for an organization. The purpose of this article is to examine the relationships among work passion, subjective well-being, career adaptability, and turnover intention for Chinese government employees. The article consists of an empirical study with a sample of 472 government employees in Shandong Province, China. Participants completed a series of questionnaires in three waves. The results indicate that harmonious passion is negatively related to turnover intention and that obsessive passion is positively related to turnover intention. Additionally, the relationship between harmonious/obsessive passion and turnover is mediated by subjective well-being, and career adaptability moderates the relationship between harmonious/obsessive passion and subjective well-being. Implications are discussed.
A solution-processed method is developed to fabricate fully transparent resistive random access memory (RRAM) devices with a configuration of FTO/ZrO2/ITO, where the zirconium dioxide (ZrO2) layer was firstly deposited on fluorine tin oxide (FTO) substrate by sol-gel and then indium tin oxide (ITO) films were deposited on ZrO2 layer by sol-gel as the top electrodes.The solution processed FTO/ZrO2/ITO based RRAM devices show the fully transparency and excellent bipolar resistance switching behaviors. The resistance ratio between high and low resistance states was more than 10, and more than 100 switching cycles and good data retention and multilevel resistive switching have been demonstrated.
The effect of Y dopant incorporated into ZTO with different Y ratios in Y-ZTO system on the performances of ZTO-based TFTs is investigated by using sol-gel process. The proper Y doped ZTO present both high film crystallization temperature and superior electrical properties as an active channel layer of TFTs. The fabricated YZTO-based TFTs with 11% Y show the excellent devices performance such as the channel field effect mobility of 1.756 cm2/Vs, SS of 2.13 V/dec, threshold voltage of 0.8V and on/off ratio of 3.12×106.
A novel ZnO/TiO2 assorted photoelectrode for dye-sensitized solar cells (DSSCs) is proposed. The impacts of the ZnO/TiO2 assorted photoelectrode on the photovoltaic performance of dye-sensitized solar cells (DSSCs) were investigated. The measurements of the light transmission spectra showed the higher transmittance through ZnO/FTO than through FTO during the effective wavelength region of 536nm˜800nm for DSSCs, indicating that ZnO/TiO2 assorted photoelectrode is beneficial for the photovoltaic performance of DSSCs. The measurements on the photovoltaic characteristics of the DSSC cell indicate that the inserted ZnO layer can cause the increased open circuit voltage (Voc) more than 70 mV and fill factor (FF) but the decreased short circuit current. The enhanced Voc and FF could be attributed to the suppressed the recombination of photon-generated carriers between the ZnO/TiO2 assorted photoelectrode and electrolyte (dye) compared to TiO2 photoelectrode. However, the additional series resistance of inserted ZnO layer causes the reduced short circuit current. The optimized conversion efficiency can be achieved in the DSSC with ZnO/TiO2 assorted photoelectrode by using low series resistance of ZnO layer.
