| 1 | Identification of Hydrocarbon Potential of Talhar Shale: Member of Lower Goru Formation Using Well Logs Derived Parameters, Southern Lower Indus Basin, Pakistan显示文摘Using well logs data only, the evaluation of shale gas hydrocarbon potential of Talhar Shale Member of Lower Goru Formation has been a challenge in Southern Lower Indus Basin in Pakistan. Well logs data analysis is helpful to evaluate the gas potential of source shale rocks. We introduced and applied empirical and graphical method to fulfil this task and derived geochemical parameters from well logs data. The method mentioned is cheap and fast. Talhar Shale has kerogen type III and type II which are montmorillonite clay and have potential to produce oil and gas. Talhar Shale has better sorption property. Empirical formulas are used to derive parameters, using well logs of porosity, density and uranium. Porosity and volume of kerogen, calculated from density log, give average values of 11.8% and 11.4%. Average value of level of maturity index(LMI) derived from log is 0.54, which indicates that it is at the early stage of maturity. Vitrinite reflectance is between 0.5%–0.55% as calculated by graphical method and empirical formula. Talhar Shale is at onset of oil generation, with main products of oil and gas. It is a good potential source in the study area. | Muhsan Ehsan Hanming Gu Malik Muhammad Akhtar Saiq Shakeel Abbasi Zaheen Ullah | 2018 | Journal of Earth Science2018，29，3： | 4 |

| 8 | An UPLC-MS/MS method to monitor Estriol injection and comparison of pharmacokinetic characteristics after irradiation显示文摘Objective:To develop an UPLC-MS/MS method for the accurate quantification of Estriol(E3),a new radioprotective agent,and observe the variation in pharmacokinetic characteristics of E3 after irradiation.As a hormone drug,the gender differences of E3 metabolism were also concerned here.Methods:Various chromatographic and mass spectrometric conditions of E3 were optimized.The specificity,linearity,precision and accuracy of UPLC-MS/MS method were validated.Twenty SD rats,half male and half female,were administered with intramuscular(im)injection of 2.7 mg/kg E3,and then divided randomly into two groups,sham-irradiated group(Con)and irradiated group(IR).IR group was irradiated to 7 Gy ofγ-rays.Blood samples were collected at different times post-irradiation and E3 concentrations were detected.The changes of concentration-time variation and pharmacokinetic parameters for E3 after irradiation were investigated,together with metabolic differences between male and female rats.Results:The range of the calibration curve of UPLC-MS/MS for E3 was 1.00–200.0 ng/mL.Con group reached maximum concentration(Cmax)(77.57±18.71)ng/mL at(0.68±0.29)h(Tmax)after im injection.The drug concentration-time profiles and pharmacokinetic parameters of E3 were consistent before and after irradiation.The areas under time curve(AUC0-t)of E3 were(353±74)h⋅ng/mL for Con group,and(299±74)h⋅ng/mL for IR group(P>0.05).There were also no statistical differences in pharmacokinetic parameters between female and male rats.The elimination half-lifes(T1/2)of males and females were(3.02±0.68)h and(3.01±0.42)h in Con group,and(3.64±0.51)h and(3.38±0.60)h in IR group,respectively(P>0.05).Conclusion:A rapid and sensitive UPLC-MS/MS method for determination of E3 was established.The pharmacokinetic characteristics of E3 in rat were not affected by 7 Gy irradiation and gender differences.This study provided a theoretical basis for the development and application of new radiation injury treatment drug。 | Hanming Zhang Zhiyun Meng Tong Ye Taoyun Liu Jian Li Fei Ma Ruolan Gu Xiaoxia Zhu Zhuona Wu Guifang Dou Hui Gan | 2021 | Radiation Medicine and Protection2021，2，2： | 0 |
