The compound(E)-2-benzylidene-3-(cyclohexylamino)-2,3-dihydro-1 H-inden-1-one(BCI) is known as an inhibitor of dual specific phosphatase 1/6 and mitogen-activated protein kinase. However, its precise anti-lung cancer mechanism remains unknown. In this study, the effects of BCI on the viability of non-small cell lung cancer cell lines NCI-H1299, A549, and NCI-H460 were evaluated. We confirmed that BCI significantly inhibited the viability of p53(-) NCI-H1299 cells as compared to NCI-H460 and A549 cells, which express wild-type p53. Furthermore, BCI treatment increased the level of cellular reactive oxygen species and pre-treatment of cells with N-acetylcysteine markedly attenuated BCI-mediated apoptosis of NCI-H1299 cells. BCI induced cellular morphological changes, inhibited viability, and produced reactive oxygen species in NCI-H1299 cells in a dose-dependent manner. BCI induced processing of caspase-9, caspase-3, and poly ADP-ribose polymerase as well as the release of cytochrome c from the mitochondria into the cytosol. In addition, BCI downregulated Bcl-2 expression and enhanced Bax expression in a dose-dependent manner in NCI-H1299 cells. However, BCI failed to modulate the expression of the death receptor and extrinsic factor caspase-8 and Bid, a linker between the intrinsic and extrinsic apoptotic pathways in NCI-H1299 cells. Thus, BCI induces apoptosis via generation of reactive oxygen species and activation of the intrinsic pathway in NCI-H1299 cells.

Trends in the incidence of cryptorchidism and hypospadias of registry-based data in Korea： a comparison between industrialized areas of petrochemical estates and a non-industrialized area

引用

Asian Journal of Andrology 2011年第5期13卷 715-718页

作者： sae Chul Kim Su Kyoung kwon Yeon Pyo Hong Department of Urology Chung-Ang University College of Medicine Seoul 156-756 Korea Department of Preventive Medicine Chung-Ang University College of Medicine Seoul 156-756 Korea

This study aimed to represent the recent trends in the nationwide incidence of cryptorchidism and hypospadias in Korea, and to determine whether there is evidence of spatial heterogeneity in the incidence. The incidence was calculated as the number of newly diagnosed patients （males） during the first 4 years after a live birth in a population, nationally and regionally （a non-industrialized area （Chuncheon） and petrochemical estates （Yeocheon and Ulsan））, between 2000 and 2005. The data （numerator） for new patients were acquired from the National Health Insurance Review Agency, and the data （denominator） for the resident registration population were from the National Statistical Office. Between 2000 and 2005, the national incidence of cryptorchidism and hypospadias had an increased tendency from 5.01 to 17.43 per 10 000 persons and from 1.40 to 3.28 per 10 000 persons, respectively. The incidence of cryptorchidism was significantly higher in Yeocheon （throughout the study period） and in Ulsan （2001, 2002, 2004 and 2005） than the national incidence, whereas the incidence in Chuncheon was significantly lower in 2001 and 2002. It was difficult to compare the rates of hypospadias yearly and regionally because of the small number of cases. In conclusion, the incidence of cryptorchidism has recently increased in Korea. The petrochemical estates, Yeocheon and Ulsan, had a significantly higher incidence of cyptorchidism than the national incidence, which suggests that further study is needed to obtain a more precise estimation of the trends in the incidence of the anomalies and to confirm the association between petrochemicals and the anomalies.

Asian Journal of Andrology 2000年第3期2卷 161-166页

作者： sae-Chul Kim Department of Urology College of Medicine Chung-Ang University Seoul Korea

We have done consecutive studies to investigate the effects of impaired lipid metabolism on the contractile and re-laxation response of cavernous smooth muscles and to elucidate its pathogenesis: 1) incidence of hyperlipidemia in im-potent patients; 2) erection response to intracavemous injection of papaverine in impotent patients with hyperlipidemia;3) relaxation responses of isolated cavemosal smooth muscles to endothelium-independent and endothelium-dependentvasodilators in impotent patients with hypercholesterolemia or hypertriglyceridemia; 4) involvement of superoxide radi-cal in the impaired endothelium-dependent relaxation of cavemous smooth muscle in hypercholesterolemic rabbits; S)effects of isolated lipoproteins and triglyceride, combined oxidized LDL plus triglyceride, and combined oxidized LDLplus HDL on contractile and relaxation response of rabbit cavemous smooth muscles; 6) involvement of e-NOS in theimpaired endothelium-dependent relaxation of cavemous smooth muscle in hypercholesterolemic rabbit. Hypercholes-terolemia may cause impairment of endothelium-dependent relaxation. Oxidized LDL is the major causative cholesterolof the impaired relaxation response. A chain reaction, the production of superoxide radicals and functional impairmentof eNOS may be a major cause of the functional impairment in the early stages of hypercholesterolemia.

Higher heating value prediction of torrefaction char produced from non-woody biomass

引用

Frontiers in Energy 2015年第4期9卷 461-471页

作者： Nitipong SOPONPONGPIPAT Dussadeeporn SITTIKUL Unchana sae-UENG Department of Mechanical Engineering Faculty of Engineering and Industrial Technology Silpakom University Nakhon Pathom 73000 Thailand

The higher heating value of five types of non- woody biomass and their torrefaction char was predicted and compared with the experimental data obtained in this paper. The correlation proposed in this paper and the ones suggested by previous researches were used for prediction. For prediction using proximate analysis data, the mass fraction of fixed carbon and volatile matter had a strong effect on the higher heating value prediction oftorrefaction char of non-woody biomass. The high ash fraction found in torrefied char resulted in a decrease in prediction accuracy. However, the prediction could be improved by taking into account the effect of ash fraction. The correlation developed in this paper gave a better prediction than the ones suggested by previous researches, and had an absolute average error （AAE） of 2.74% and an absolute bias error （ABE） of 0.52%. For prediction using elemental analysis data, the mass fraction of carbon, hydrogen, and oxygen had a strong effect on the higher heating value, while no relationship between the higher heating value and mass fractions of nitrogen and sulfur was discovered. The best correlation gave an AAE of 2.28% and an ABE of 1.36%.

Several dynamic tests with vasoactive drags are available for evaluating penile vascular inflows and outflows,ranging from simple pharmacologic test to more invasive radiologic sets. However, there is still no perfect single testto reflect the penile vascular flow. All possible efforts should be exerted to get the greatest erectile effect to avoid anunderestimation of blood flow to the corpora due to incomplete relaxation of the trabecular smooth *** of the type and frequency of anatomical variations and potential collateral routes is important in interpretingpenile arterograms and in evaluating the hemodynamic significance of suspected arterial disease.

Influence of Indian mustard (Brassica juncea) on rhizosphere soil solution chemistry in long-term contaminated soils:A rhizobox study

引用

Journal of Environmental Sciences 2010年第1期22卷 98-105页

作者： kwon-Rae Kim Gary Owens Soon-lK kwon Climate Change & Agroecology Division Department of Agricultural EnvironmentNational Academy of Agricultural ScienceRDARepublic of Korea Centre for Environmental Risk Assessment and Remediation University of South Australia

This study investigated the influence of Indian mustard （Brassicajuncea） root exudation on soil solution properties （pH, dissolved organic carbon （DOC）, metal solubility） in the rhizosphere using a rhizobox. Measurement was conducted following the cultivation of Indian mustard in the rhizobox filled four different types of heavy metal contaminated soils （two alkaline soils and two acidic soils）. The growth of Indian mustard resulted in a significant increase （by 0.6 pH units） in rhizosphere soil solution pH of acidic soils and only a slight increase （〈 0.1 pH units） in alkaline soils. Furthermore, the DOC concentration increased by 17-156 mg/L in the rhizosphere regardless of soil type and the extent of contamination, demonstrating the exudation of DOC from root. Ion chromatographic determination showed a marked increase in the total dissolved organic acids （OAs） in rhizosphere. While root exudates were observed in all soils, the amount of DOC and OAs in soil solution varied considerably amongst different soils, resulting in significant changes to soil solution metals in the rhizosphere. For example, the soil solution Cd, Cu, Pb, and Zn concentrations increased in the rhizosphere of alkaline soils compared to bulk soil following plant cultivation. In contrast, the soluble concentrations of Cd, Pb, and Zn in acidic soils decreased in rhizosphere soil when compared to bulk soils. Besides the influence of pH and DOC on metal solubility, the increase of heavy metal concentration having high stability constant such as Cu and Pb resulted in a release of Cd and Zn from solid phase to liquid phase.
