9Oxidative Stress before and after Operation in Patients with Chronic Cholecystitis Containing Gallstone显示文摘To study the relationship of oxidative, antioxidative constituents and antioxidases in blood with chronic cholecystitis containing gallstone, levels of lipoperoxides (LPO), nitric oxide (NO), vitamin C(VC), vitamin E (VE) and β carotene (β CAR) in plasma as well as level of LPO, activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH Px) in erythrocytes were investigated by spectrophotometric assay in 107 patients with this condition (PCg) and 100 healthy volunteers (HVs). Compared with HVs group, the average value of LPO and NO in plasma and that of LPO in erythrocytes of PCg group were significantly increased ( P <0.0001), while that of VC, VE and β CAR in plasma and the average activities of SOD, CAT and GSH Px in erythrocytes were significantly decreased ( P <0.0001). Linear regression and correlation analysis for 107 preoperative PCg showed that the value of LPO and NO in plasma and that of LPO in erythrocytes of PCg gradually increased ( P <0.0001), representing a significant linear positive correlation. The value of VC, VE and β CAR in plasma and that of SOD, CAT and GSH Px in erythrocytes of PCg gradually decreased ( P <0.0001), representing a significant linear negative correlation. Stepwise regression and correlation analysis for 107 preoperative PCg suggested that the closest correlation was observed between the course of disease and the value of NO and VC in plasma and that of SOD, GSH Px and LPO in erythrocytes, r =0.7306, F =32.1408, P <0.0001. Compared with the preoperative PCg group, the average value of LPO and NO in plasma and that of LPO in erythrocytes of the postoperative PCg group were significantly decreased ( P <0.0001). Furthermore, the average value of VC in plasma and that of SOD, CAT and GSH Px in erythrocytes of the postoperative PCg group were significantly increased ( P <0.0001), whereas no significant difference was found between their average value of VE and β CAR in plasma. These findings suggested that oxidative stress was an aggravating pathological condition in PCg group. Therefore, we recommend that in treating PCg, antioxidants such as VC, VE, β CAR should be given in order to alleviate their potential oxidative damages.ZHOU JUN FU , CHEN PENG , YANG JIN LU +, ZHU YOU GEN + PENG CHENG HONG , AND WU YU LIAN  The 2nd Affiliated Hospital, Medical College of Zhejiang University, 88 Jiefang Road, Hangzhou, 310009, Zhejian 2000Biomedical and Environmental Sciences2000,13,4:10

12Traditional El Nio and El Ni o Modoki Revisited:Is El Nio Modoki Linearly Independent of Traditional El Nio?显示文摘The present study revisited the first two leading modes of tropical Pacific sea surface temperature anomalies (SSTA) during the period of 1979 2008.It is suggested that the so-called El Nio Modoki,which is captured by the second mode,exists objectively and exhibits obvious differences from traditional El Nio,which is captured by the first mode,in terms of its spatial characteristics.Furthermore,the authors found that El Nio Modoki is linearly independent of traditional El Nio;hence,it cannot be described as part of the traditional El Nio evolution,and vice versa.LI Gen REN Bao-Hua YANG Cheng-Yun ZHENG Jian-Qiu 2010Atmospheric and Oceanic Science Letters2010,3,2:7
13Transfer of mitochondria from mesenchymal stem cells derived from induced pluripotent stem cells attenuates hypoxia-ischemia-induced mitochondrial dysfunction in PC12 cells显示文摘Mitochondrial dysfunction in neurons has been implicated in hypoxia-ischemia-induced brain injury.Although mesenchymal stem cell therapy has emerged as a novel treatment for this pathology,the mechanisms are not fully understood.To address this issue,we first co-cultured 1.5×10^5 PC12 cells with mesenchymal stem cells that were derived from induced pluripotent stem cells at a ratio of 1:1,and then intervened with cobalt chloride(CoCl2)for 24 hours.Reactive oxygen species in PC12 cells was measured by Mito-sox.Mitochondrial membrane potential(ΔΨm)in PC12 cells was determined by JC-1 staining.Apoptosis of PC12 cells was detected by terminal deoxynucleotidal transferase-mediated dUTP nick end-labeling staining.Mitochondrial morphology in PC12 cells was examined by transmission electron microscopy.Transfer of mitochondria from the mesenchymal stem cells derived from induced pluripotent stem cells to damaged PC12 cells was measured by flow cytometry.Mesenchymal stem cells were induced from pluripotent stem cells by lentivirus infection containing green fluorescent protein in mitochondria.Then they were co-cultured with PC12 cells in Transwell chambers and treated with CoCl2 for 24 hours to detect adenosine triphosphate level in PC12 cells.CoCl2-induced PC12 cell damage was dose-dependent.Co-culture with mesenchymal stem cells significantly reduced apoptosis and restoredΔΨm in the injured PC12 cells under CoCl2 challenge.Co-culture with mesenchymal stem cells ameliorated mitochondrial swelling,the disappearance of cristae,and chromatin margination in the injured PC12 cells.After direct co-culture,mitochondrial transfer from the mesenchymal stem cells stem cells to PC12 cells was detected via formed tunneling nanotubes between these two types of cells.The transfer efficiency was greatly enhanced in the presence of CoCl2.More importantly,inhibition of tunneling nanotubes partially abrogated the beneficial effects of mesenchymal stem cells on CoCl2-induced PC12 cell injury.Mesenchymal stem cells reduced CoCl2-induced PC12 cell injury and these effects were in part due to efficacious mitochondrial transfer.Yan Yang Gen Ye Yue-Lin Zhang Hai-Wei He Bao-Qi Yu Yi-Mei Hong Wei You Xin Li 2020Neural Regeneration Research2020,15,3:6

16Thermal performance analysis of non-uniform height rectangular fin based on constructal theory and entransy theory显示文摘A model of non-uniform height rectangular fin, in which the variation of base's thickness and width are taken into account, is established in this paper. The dimensionless maximum thermal resistance(DMTR) and the dimensionless equivalent thermal resistance(DETR) defined based on the entransy dissipation rate(EDR) are taken as performance evaluation indexes. According to constructal theory, the variations of the two indexes with the geometric parameters of the fin are analyzed by using a finite-volume computational fluid dynamics code, the effects of the fin-material fraction on the two indexes are analyzed. It is found that the two indexes decrease monotonically as the ratio between the front height and the back height of the fin increases subjected to the non-uniform height rectangular fin. When the model is reduced to the uniform height fin, the two indexes increase first and then decrease with increase in the ratio between the height of the fin and the fin space. The fin-material fraction has no effect on the change rule of the two indexes with the ratio between the height of the fin and the fin space. The sensitivity of the DETR to the geometric parameters of the fin is higher than that of the DMTR to the geometric parameters. The results obtained herein can provide some theoretical support for the thermal design of rectangular fins.YANG Ai Bo CHEN Lin Gen XIE Zhi Hui FENG Hui Jun SUN Feng Rui 2016Science China(Technological Sciences)2016,59,12:4

18Performance of compact plastic scintillator strips with wavelength shifting fibers using a photomultiplier tube or silicon photomultiplier readout显示文摘This study presents the design and performance results for compact plastic scintillator strips using a wavelength shifting fiber(WLS-fiber)readout with dimensions of 0.1 m×0.02 m×2 m.This approach was evaluated as a candidate for a cosmic-ray muon detector for the Taishan Antineutrino Observatory(JUNO-TAO).The strips coupled with 3-inch photomultiplier tubes(PMTs)were measured and compared between the single-end and double-end readout options.Additionally,a strip using the double-end option coupling with a silicon photomultiplier(SiPM)was further evaluated and compared with the results obtained using PMTs.The performance of the strips was determined by a detailed survey along their length with a cosmicray muon after detailed characterization of the 3-inch PMTs and SiPMs.The proposed design employing a compact plastic scintillator strip with WLS-fiber coupling to a SiPM provides a good choice for cosmic-ray muon veto detectors,particularly when detector dimensions must be limited.Min Li Zhi‑Min Wang Cai‑Mei Liu Pei‑Zhi Lu Guang Luo Yuen‑Keung Hor Jin‑Chang Liu Chang‑Gen Yang 2023Nuclear Science and Techniques2023,34,2:3
