Purpose: This study aimed to use a web-based survey to investigate the correlation between job satisfaction and marital quality and to identify the association of demographics with job satisfaction and marital quality. Methods: Married nurses (N = 2,296) completed the questionnaires. Correlations and linear regression analyses were carried out. Results: Both marital quality and job satisfaction were relatively low. Additionally, marital quality was positively correlated with job satisfaction. Age, marital status (in years) and average daily hours spent with spouse had positive impact on job satisfaction. Multiple linear regression analyses showed that age, monthly income, average daily hours spent with spouse and marital quality were positively associated with job satisfaction. Conclusion: Because of the shifts nurses working, there is little time for nurses to spend with their spouses and family. It is recommended that hospital leaders could provide more flexibility with nurses’ shift choices so nurses can arrange their work-life balance better. Other considerations like reducing workload and reducing working hours should be promoted as options. Nurse managers could offer counseling services including strategies to cope with the balance between work and life. This effort could improve job satisfaction and reduce the rate of turnover of nurses.

Background/Aims To determine the value of salivary pepsin in discriminating sub-types of gastroesophageal reflux disease (GERD) and GERD-related disorders. Methods Overall, 322 patients with different sub-types of GERD and 45 healthy controls (HC) were studied. All patients took Gastroesophageal Reflux Disease Questionnaire (GerdQ) and underwent endoscopy and 24-hour esophageal pH monitoring and manometry. Salivary pepsin concentration (SPC) was detected by using colloidal gold double-antibody immunological sandwich assay. Oral esomeprazole treatment was administrated in the patients with non-erosive reflux disease (NERD) and extra-esophageal symptoms (EES). Results Compared to HC, patients with erosive esophagitis, NERD, EES, EES plus typical GERD symptoms, or Barrett’s esophagus had a higher prevalence of saliva and SPC (all P < 0.001). There was no significant difference in the positive rate for pepsin in patients with functional heartburn or GERD with anxiety and depression, compared to HC. After esomeprazole treatment, the positive rate and SPC were significantly reduced in NERD (both P < 0.001) and in EES (P = 0.001 and P = 0.002, respectively). Of the 64 NERD patients, 71.9% (n = 46) were positive for salivary pepsin, which was significantly higher than the rate (43.8%, n = 28) of pathological acid reflux as detected by 24-hour esophageal pH monitoring (P = 0.002). Conclusions Salivary pepsin has an important significance for the diagnosis of GERD and GERD-related disorders. Salivary pepsin and 24-hour esophageal pH monitoring may complement with each other to improve the diagnostic efficiency.

An integral imaging system enabling an enhanced depth of field is proposed based on spatial filtering. In the proposed system, spatial filtering is used on each elemental image to obtain a depth-enhanced elemental image in the pickup stage, and the obtained elemental images are composed to form an elemental image array for the computational reconstruction in the display stage. A preliminary experiment was carried out, and the experiment results verified the feasibility of the system.

The structural stability of beta uranium (-U) is investigated by using the projector augmentedwave (PAW) method based on the density function theory (DFT). Optimized lattice parameters arein agreement with other available data. Especially, the energy per atom and the phonon propertiesmanifest that the model described by using space group No. 102 can be stabilized vibrationallyand energetically. A reasonable agreement with the experimental data for the phonon entropycorresponding to the proper structure has been successfully achieved. Moreover, the thermodynamicfunctions are predicated at elevated temperatures.

Lycium barbarum polysaccharides (LBPs) are important functional constituents in red-colored fruits of L. barbarum (Guo Qi Zi, a well-known traditional Chinese medicinal plant commonly known as Goji berry or wolfberry). The influence of LBP on human prostate cancer cells was systematically investigated in vitro and in vivo. The in vitro effects of LBP on two cell lines (PC-3 and DU-145) were examined by using trypan blue exclusion staining, single-cell gel electrophoresis, flow cytometry, terminal dUTP nick-end labeling assay, and immunohistochemical assay (assessment of Bcl-2 and Bax expression). The in vivo effect of LBP on PC-3 cells was assessed in the nude mouse xenograft tumor model. The in vitro results showed that LBP can dose- and time-dependently inhibit the growth of both PC-3 and DU-145 cells. LBP caused the breakage of DNA strands of PC-3 and DU-145 cells; the tail frequency and tail length were significantly higher than that of control cells. LBP also markedly induced PC-3 and DU-145 cell apoptosis, with the highest apoptosis rates at 41.5% and 35.5%, respectively. The ratio of Bcl-2/Bax protein expression following LBP treatments decreased significantly with a dose–effect relationship, which suggested that LBP can regulate the expression of Bcl-2 and Bax to induce apoptosis of PC-3 and DU-145 cells. The in vivo experimental results indicate that LBP might significantly inhibit PC-3 tumor growth in nude mice. Both the tumor volume and weight of the LBP treatment group were significantly lower than those of the control group.

Loading noble metal and exploring suitable morphology to achieveexcellent gas-sensing performance is very crucial for the fabrication ofgas sensors. We have successfully synthesized Au-loaded ZnO (Au/ZnO) nanospindles (NSs) through a really facile procedure involving aprecipitation and subsequent microwave irradiation. The as-preparedproducts have been characterized by X-ray diffraction (XRD), scanningelectron microscope (SEM). The formation and gas-sensing mechanismof Au/ZnO NSs were discussed. The SEM micrographs revealed aninteresting morphological evolution of the Au/ZnO NSs with Auloadingcontent ranging from 0 at. % to 7 at. %. The nanostructures wereemployed for gas-sensing measurement toward various gases. Itindicated that the Au/ZnO NSs based sensor showed a highly enhancedresponse (226.81) to 400 ppm acetone gas at a relatively low workingtemperature (270°C), and exhibited a fast response (1 s) and recoveryspeed (10 s). The highly enhanced acetone gas sensitivity of Au/ZnONSs based sensor could be attributed to its enhanced polarity owing tothe peculiar morphology, Schottcky barriers, as well as catalytic effect ofAu NPs.

Several catalysts of the general formula, MMnOx (M = Co, Ni, Fe and Cu), were synthesised through the impregnation method; their activities were shown to be enhanced by the addition of a small amount of Pd (0.01–0.1 wt%). These catalysts exhibit different activities for the catalytic oxidation of CO, due to the different valence states of various transition metal oxides. The introduction of Pd prominently enhanced both the reduction and oxidation capabilities of the catalysts. These catalysts were optimised for oxidation activities by designing orthogonal experiments. Based upon the catalysts’ properties, the stability of these samples and their ability to resist steam over Pd/CoMnOx/cordierite were investigated.

Al, Pd co-doped ZnO nanoparticles (NPs) synthesized using a solution combustion method and subsequent annealing process under various atmospheres, including air, nitrogen, and hydrogen, were characterized using x-ray diffraction, energy-dispersive x-ray spectroscopy, fieldemission scanning electron microscopy, transmission electron microscopy, and photoluminescence spectroscopy. The gas-sensing properties of the sensors based on the NPs were also examined. The results indicated that the Al, Pd co-doped ZnO NPs, with an average crystallite size of 10 nm, exhibited enhanced gas-sensing performance compared with that of pure ZnO and Al-doped ZnO. The response of the Al, Pd co-doped ZnO NPs annealed in N2 to ethanol (49.22) was nearly 5.7 times higher than that to acetone (8.61) and approximately 20 - 27 times higher than that to benzene (2.38), carbon monoxide (2.23), and methane (1.78), which demonstrates their excellent selectivity to ethanol versus other gases. This high ethanol response can be attributed to the combined effects of the small size, Schottky barrier, lattice defects, and catalysis.

Powdery photocatalyst has shown great potential in wastewater treatment, yet the low reusability is stillits deficiency. In this work, we prepared magnetically recyclable lanthanum-nitrogen co-doped titania/CaFe2O4/diatomite (LN-TCD) ternary material by sol-gel technology. The photocatalytic activity of thismaterial was evaluated via the decomposition of antibiotic oxytetracycline and disinfection of bacteriaEscherichia coli under visible light. Charge transfer took place at the interface between titania andCaFe2O4, and improved the photocatalytic activity. The photodecomposition rate was accelerated by thehigh adsorption ability of substrate diatomite. The optimal preparation and experimental factors weredetermined, and the decomposition mechanism was proposed.
