| 1 | Rapid Detection of Oil Pollution in Soil by Using Laser-Induced Breakdown Spectroscopy显示文摘Detection of oil pollution in soil has been carried out using laser-induced breakdown spectroscopy(LIBS). A pulsed neodymium-doped yttrium aluminum garnet(Nd:YAG) laser(1,064 nm, 8 ns, 200 mJ) was focused onto pelletized soil samples. Emission spectra were obtained from oil-contaminated soil and clean soil. The contaminated soil had almost the same spectrum profile as the clean soil and contained the same major and minor elements. However, a C–H molecular band was clearly detected in the oil-contaminated soil, while no C–H band was detected in the clean soil. Linear calibration curve of the C–H molecular band was successfully made by using a soil sample containing various concentrations of oil. The limit of detection of the C–H band in the soil sample was 0.001 mL/g. Furthermore, the emission spectrum of the contaminated soil clearly displayed titanium(Ti) lines, which were not detected in the clean soil. The existence of the C–H band and Ti lines in oil-contaminated soil can be used to clearly distinguish contaminated soil from clean soil. For comparison, the emission spectra of contaminated and clean soil were also obtained using scanning electron microscope-energy dispersive X-ray(SEM/EDX) spectroscopy,showing that the spectra obtained using LIBS are much better than using SEM/EDX, as indicated by the signal to noise ratio(S/N ratio). | Ali KHUMAENI Wahyu Setia BUDI Asep Yoyo WARDAYA Rinda HEDWIG Koo Hendrik KURNIAWAN | 2016 | Plasma Science and Technology2016，18，12： | 2 |

| 9 | Prediction of hereditary nonpolyposis colorectal cancer using mRNA MSH2 quantitative and the correlation with nonmodifiable factor显示文摘BACKGROUND Hereditary non-polyposis colon cancer is a dominantly inherited syndrome of colorectal cancer(CRC),with heightened risk for younger population.Previous studies link its susceptibility to the DNA sequence polymorphism along with Amsterdam and Bethesda criteria.However,those fail in term of applicability.AIM To determine a clear cut-off of MSH2 gene expression for CRC heredity grouping factor.Further,the study also aims to examine the association of risk factors to the CRC heredity.METHODS The cross-sectional study observed 71 respondents from May 2018 to December 2019 in determining the CRC hereditary status through MSH2 mRNA expression using reverse transcription-polymerase chain reaction and the disease’s risk factors.Data were analyzed through Chi-Square,Fischer exact,t-test,Mann-Whitney,and multiple logistics.RESULTS There are significant differences of MSH2 within CRC group among tissue and blood;yet,negative for significance between groups.Through the blood gene expression fifth percentile,the hereditary CRC cut-off is 11059 fc,dividing the 40 CRC respondents to 32.5%with hereditary CRC.Significant risk factors include age,family history,and staging.Nonetheless,after multivariate control,age is just a confounder.Further,the study develops a probability equation with area under the curve 82.2%.CONCLUSION Numerous factors have significant relations to heredity of CRC patients.However,true important factors are staging and family history,while age and others are confounders.The study also established a definite cut-off point for heredity CRC based on mRNA MSH2 expression,11059 fc.These findings shall act as concrete foundations on further risk factors and/or genetical CRC future studies. | Tjahjadi Robert Tedjasaputra Mochammad Hatta Muh Nasrum Massi Rosdiana Natzir Agussalim Bukhari Rina Masadah Muh Lutfi Parewangi Prihantono Prihantono Rinda Nariswati Vincent Tedjasaputra | 2021 | World Journal of Gastrointestinal Pathophysiology2021，12，6： | 0 |
