| 1 | Stress and sleep quality in doctors working on-call shifts are associated with functional gastrointestinal disorders显示文摘AIM To investigate the role of sleep quality and psychosocial problems as predictors of functional gastrointestinal disorders(FGIDs) in doctors that work 24 hour-on-call shifts.METHODS In this cross-sectional observation study, using the Rome Ⅲ Questionnaire and Pittsburgh Sleep Quality Index(PSQI), we analyzed 170 doctors with 24 houron-call shifts. RESULTS Among the participants that had experienced a 24 hour-on-call shift within the last 6 mo, 48(28.2%) had FGIDs. Overall prevalence of irritable bowel syndrome(IBS) and functional dyspepsia(FD) were 16.5% and 17.1%, respectively, with 5.3% exhibiting both. Sleep scores(PSQI)(8.79 ± 2.71 vs 7.30 ± 3.43, P = 0.008), the presence of serious psychosocial alarm(83.3%vs 56.6%, P = 0.004), and the proportion of doctors who experienced over two months of recent on-call work(81.2% vs 68.9%, P = 0.044) were significantly different between individuals with or without FGIDs. Multivariate analysis revealed that presenting serious psychosocial alarm was an independent risk factor for prevalence of FD(OR = 5.47, 95%CI: 1.06-28.15, P = 0.042) and poor sleep quality(PSQI ≥ 6) was a predictor of IBS(OR = 4.17, 95%CI: 1.92-19.02, P = 0.016). CONCLUSION Physicians should recognize the role of sleep impairment and psychological stress in the development of FGIDs and a comprehensive approach should be considered to manage patients with FGIDs. | Soo-Kyung Lim Seung Jin Yoo Dae Lim Koo Chae A Park Han Jun Ryu Yong Jin Jung Ji Bong Jeong Byeong Gwan Kim Kook Lae Lee Seong-Joon Koh | 2017 | World Journal of Gastroenterology2017，23，18： | 2 |

| 4 | Superior electrocatalytic negative electrode with tailored nitrogen functional group for vanadium redox flow battery显示文摘Development of electrodes with high electrocatalytic activity and stability is essential for solving problems that still restrict the extensive application of vanadium redox flow batteries(VRFBs).Here,we designed a novel negative electrode with superior electrocatalytic activity by tailoring nitrogen functional groups,such as newly formed nitro and pyridinic-N transformed to pyridonic-N,from the prenitrogen-doped electrode.It was experimentally confirmed that an electrode with pyridonic-N and nitro fuctional groups(tailored nitrogen-doped graphite felt,TNGF) has superior electrocatalytic acivity with enhanced electron and mass transfer.Density functional theory calulations demonstrated the pyridonic-N and nitro functional groups promoted the adsorption,charge transfer,and bond formation with the vanadium species,which is consistent with expermental results.In addition,the V2+/V3+redox reaction mechanism on pyridonic-N and nitro functional groups was estabilised based on density functional theory(DFT) results.When TNGF was applied to a VRFB,it enabled enhanced-electrolyte utilization and energy efficiencies(EE) of 57.9% and 64.6%,respectively,at a current density of 250 mA cm^(-2).These results are 18.6% and 8.9% higher than those of VRFB with electrode containing graphitic-N and pyridinicN groups.Interestingly,TNGF-based VRFB still operated with an EE of 59% at a high current density of300 mA cm^(-2).The TNGF-based VRFB exhibited stable cycling performance without noticeable decay of EE over 450 charge-discharge cycles at a current density of 250 mA cm^(-2).The results of this study suggest that introducing pyridonic-N and nitro groups on the electrode is effective for improving the electrochemical performance of VRFBs. | Min Gu Kang Wook Ahn Joonhee Kang Shin Ae Song Kiyoung Kim Ju Young Woo Yong-Cheol Jeong Bonwook Koo Dae Soo Jung Sung Nam Lim | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
