05). The resin infiltration technique appears to aid in sealing enamel AWL and may help provide long-term protection against microleakage in enamel AWL.
In Japan, companies are required to implement a "stress check program" to prevent mental health problems in workers. To identify "high-stress" workers, the Brief Job Stress Questionnaire (BJSQ) is recommended. According to the stress check program manual issued by the government, high-stress can be defined using two criteria, either the "sum method" (simply summing the scores for each scales) or the "score converted method" (using converted scores according to the conversion table for each scales). In this study, we examined the differences in results found using these two criteria on "stress check program" data.

We used data of 71,422 workers in 117 companies and organizations who conducted stress checks in 2016. The prevalence of high-stress was calculated by applying the two criteria simultaneously, and the chi-square test was used to compare the proportion of workers with high-stress. We subsequently divided participants into the four following groups and calculated the proportion of each group group factors. Furthermore, workers were more likely to be judged as having "high-stress" when the score of the physical stress response was higher in the sum method. Hereafter, it is important to consider which criteria are applied when discussing proportions of high-stress. Further research is needed to examine which criteria will predict health disorders.
Compared to the sum method, 1.5% more high-stress workers were observed using the converted method, and this result was similar for individual and employment-related factors. Furthermore, workers were more likely to be judged as having "high-stress" when the score of the physical stress response was higher in the sum method. Hereafter, it is important to consider which criteria are applied when discussing proportions of high-stress. Further research is needed to examine which criteria will predict health disorders.Monitoring the changes in the level of KRAS point mutation (the concentration fraction of the KRAS point mutated DNA to the total DNA) in clinical treatment progress can guide and greatly improve the personalized therapy and therapeutic evaluation of patients with cancer. In this work, based on FRET fluorescence quenching and apyrimidinic site-induced guanine/pterin specific binding, we developed a pterin-FAM-TAMRA tri-color fluorescence sensing system to assess the level of KRAS point mutation in one step. The responses from TAMRA displayed good and similar linear correlations in the range from 60 nM to 2 μM for all four types of DNA, resulting in a common linear equation related to the T-DNA concentration (NΔFTAMRA = 2.908cT-DNA + 0.364). Meanwhile, the responses from pterin showed excellent selectivity to W-DNA and an excellent linear correlation to the W-DNA in the concentration range from 60 nM to 1 μM (NΔFpterin = -0.364cgDNA-G + 0.034). This biosensor has an effective concentration range for detecting KRAS point mutations. Especially, because the apyrimidinic site-induced guanine/pterin binding is selective for the detection of wild-type DNA, the sensing system can be applied for clinical mutation level detection of all kinds of KRAS point mutations (G → A, G → C and G → T) in blood samples, which is crucial for the personalized therapy and therapeutic evaluation of patients with most KRAS-related cancer types.Renal cell carcinoma is a very aggressive and often fatal disease for which there are no specific biomarkers found to date. The purpose of this work was to find features that differentiate urine metabolic profiles of healthy people and cancer patients. Laser desorption/ionization mass spectrometry on gold nanostructures-based techniques were used for the metabolic analysis of urine of 50 patients with kidney cancer. Comparison with data from 50 healthy volunteers led to the discovery of several compounds that may be considered potential renal cell carcinoma (RCC) biomarkers. Statistical analysis of data allowed for the discovery of m/z values that had the greatest impact on group differentiation. A database search enabled the assignment of signals for the most promising 15 features among them serine, heptanol, 3-methylene-indolenine, 2-methyl-3-hydroxy-5-formylpyridine-4-carboxylate, phosphodimethylethanolamine, 4-methoxyphenylacetic acid, N-acetylglutamine, 3,5-dihydroxyphenylvaleric acid, hydroxyhexanoylglycine, valyl-leucine, leucyl-histidine, oleamide, 9,12,13-trihydroxyoctadecenoic acid, stearidonyl carnitine and squalene. Differences of metabolite profiles of human urine could be identified by gold nanoparticle-enhanced target (AuNPET) LDI MS method and used for the detection of renal cancer.Artisanal small gold mining (ASGM) is responsible for approximately 40% of the total Hg emissions into the atmosphere worldwide. In developing countries, many people are engaged in ASGM activities. We developed a small, simple Hg measuring device, which detects Hg in the air based on the change of the oscillation frequency of an Au electrode on a quartz crystal microbalance (QCM). This device is called QCM-Hg. We tested the viability of the QCM-Hg in various work settings including a gold mining area and gold shops. In working environments with an airborne Hg concentration of several μg m-3, the changing rate of the oscillation frequency for either 2 or 3 min corresponded with the Hg concentrations measured using the conventional method of gold amalgamation and cold vapor atomic absorption spectrometer (CVAAS). The results revealed that the QCM-Hg is a useful device for real-time Hg monitoring in actual working environments related to ASGM activities and Hg treatment facilities.The photocurrent (sample current) of insulating 0.7-μm thick polyethylene terephthalate (PET) films on conductive substrates (C, Au, Cu) was clearly measured through the substrates during soft X-ray irradiation on the PET films. X-ray absorption measurements of the PET/conductive-substrates using the total-electron-yield (TEY) method by measuring sample current easily provide the X-ray absorption spectra (XAS) of PET films, which are independent of the substrates. Tamoxifen From additional X-ray absorption measurements using self-standing PET/Au and Au/PET-films, I-V measurements, and thickness-dependent sample current measurements, it can be confirmed that electrically conductive paths form in the insulating PET film in thickness direction along the soft X-ray beam trajectory. Such phenomena enable easy and simple TEY-XAS measurements of insulating μm-order-thick samples.Sensitivity amplification strategies in label-free electrochemical immunosensors are mainly limited by redox molecules leaking and degradation of electrical conductivity caused by layers of decoration. Herein, a relatively stable and sensitive label-free electrochemical immunosensor based on a hierarchically flower-like gold microstructures/polyaniline/reduced graphene oxide/prussian blue (HFG/PANI/rGO/PB) composite modified electrode was stepwise fabricated for determination of α-fetoprotein (AFP). In this process, the effect of PANI and rGO on the proposed immunosensor was studied. In detail, PANI/rGO due to the unique electrochemical properties can effectively prevent PB leakage and form a stable sensing platform, which causes sensitive responsiveness and thus a more satisfied detection limit. Meanwhile, the HFG with good biological compatibility can effectively immobilize plenty of antibodies. Under optimal conditions, the HFG/PANI/rGO/PB modified immunosensor exhibited an excellent linearity (0.01 - 30 ng/mL) and a low detection limit (0.003 ng/mL) (S/N = 3), suitable specificity as well as stability and reproducibility towards AFP. The present work offered a promising platform for clinical hepatocellular carcinoma diagnostics.A method involving cloud point-salting out extraction (CPSOE) coupled with UHPLC-MS/MS was developed for the determination of eleven sulfonamides in milk. In this study, the type and concentration of the surfactant, de-emulsification condition, pH value, volume of n-butanol, equilibration temperature and time were optimized. For this developed method, the linear range of SAs was from 0.05 to 50 μg L-1, and the correlation coefficients were higher than 0.997. The average recoveries for SAs were from 61.32 to 91.67%, and the LOQs were less than 0.06 μg kg-1.Microvascular endothelial cells possess versatile functions and their roles in a variety of viral infections have been documented. Porcine reproductive and respiratory syndrome virus (PRRSV) infection induces severe lung inflammatory lesions in piglets, which is manifested as pulmonary endothelial dysfunction. However, the underlying mechanism of PRRSV affecting porcine pulmonary microvascular endothelial cells (PMECs) remains unknown. This study aimed to evaluate the susceptibility of PMECs to PRRSV. Primary PMECs were isolated and purified from piglet lungs, and the expression of three PRRSV receptors was characterized using immunofluorescence. Overt cytopathic effects of the PRRSV strain HN in PMECs were observed at day five post-infection, and PRRSV antigens in PMECs were determined at both RNA and protein levels using immunofluorescence and quantitative RT-PCR assays. The viral antigen significantly increased at 96 hr post-infection, and infectious virus was recovered from the supernatant of the infected PMECs. The results show that PMECs can be infected with the PRRSV strain HN, and that their receptor expression pattern is different from that of alveolar macrophages. The results of this study shed light on the potential roles of PMECs in PRRSV infection and provide a comprehensive understanding of the pathogenesis underlying its severe manifestation.Population shifts in the activated sludge microbiome of a membrane bioreactor (MBR) during the treatment of Ramen noodle-soup wastewater were analyzed by high-throughput sequencing. An MBR underwent stable treatment of wastewater containing increasing oil concentrations (from 135 to 1,350 mg/L) for 26 days; however, after feeding with wastewater containing 2,700 mg/L of oil, the mixed liquor suspended solids and transmembrane pressure exhibited gradual and rapid increases, respectively, leading to clogging of the membrane. Phylogenetic analysis revealed an oil supply-dependent increase in the abundance of Cupriavidus gilardii (relative abundance of 26.2% at Day 30) in the sludge together with Parasegetibacter terrae (9.9%) and Ferruginibacter yonginensis (9.4%). These dominant species may play important roles in noodle-soup wastewater treatment.In late March 2020, we faced a nosocomial outbreak of novel coronavirus disease 2019 (COVID-19) at Keio University Hospital, Tokyo, Japan. Presently, COVID-19 is an unprecedented worldwide biohazard, and a nosocomial outbreak can occur in any hospital at any time. Therefore, we reviewed the literature regarding hospital preparedness, the initial management of COVID-19, and the surveillance of healthcare workers (HCWs) to find information that would be generally useful for physicians when confronted with COVID-19. In terms of hospital preparedness, each hospital should develop an incident management system and establish a designated multidisciplinary medical team. To initiate case management, COVID-19 should be suspected based on patient symptoms and/or high-risk history and then should be confirmed by viral testing, such as reverse transcription polymerase chain reaction (RT-PCR) analysis. Although some patients will become critically ill, the guidelines for respiratory failure and septic shock for non-COVID-19 cases can be followed for supportive treatment.
