1煤型稀有金属矿床:成因类型、赋存状态和利用评价显示文摘煤和含煤岩系中稀有金属元素的研究,是当今煤地质学研究的热点问题之一。煤和含煤岩系中高度富集并可以开发利用的稀有金属元素包括锂、钪、钛、钒、镓、锗、硒、锆、铌、铪、钽、铀、稀土元素(包括镧系元素和钇)、贵金属元素等。以煤-锗、煤-镓、煤-铀、煤-铌、煤-稀土元素等煤型稀有金属矿床为例,论述了这些矿床的地质成因、赋存状态和利用评价方法。煤型稀有金属矿床的研究,不仅对研究煤层的地质成因、煤层对比、含煤盆地形成与后期改造、区域地质历史演化和突发地质事件可以提供重要的煤地球化学和煤矿物学证据,而且对煤炭经济循环发展、煤炭利用过程中环境保护,以及对国家稀有金属资源安全也具有重要的现实和社会意义。代世峰 任徳贻 周义平 Vladimir VSeredin 李大华 张名泉 James C Hower Colin R Ward 王西勃 赵蕾 宋晓林 2014煤炭学报2014,39,8:111
2用RFLP方法研究陕西省主要小麦品种遗传多样性及其演变显示文摘研究用RFLP方法,对我国主要小麦产区,陕西省40年代以来广为种植的小麦品种的遗传多样性进行了研究,结果表明,占总带数26.2%的HINDII酶的RFLP带具有遗传多态性。24个小麦品种平均遗传相似系数为0.948。53.8%的探针显示了多态性。平均多态性信息含量指数为0.252。陕西省小麦品种遗传多样性以70年代为最高,之后开始降低。朱列层 唐国顺 HAZEN S P KIM H S WARD R W 1999西北植物学报1999,19,2:11
3Model combining pre-transplant tumor biomarkers and tumor size shows more utility in predicting hepatocellular carcinoma recurrence and survival than the BALAD models显示文摘AIM To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma(HCC) patients after liver transplant.METHODS BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein(AFP), Lens culinaris agglutinin-reactive AFP(AFP-L3), and des-gammacarboxyprothrombin(DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD).Nicha Wongjarupong Gabriela M Negron-Ocasio Roongruedee Chaiteerakij Benyam D Addissie Essa A Mohamed Kristin C Mara William S Harmsen J Paul Theobald Brian E Peters Joseph G Balsanek Melissa M Ward Nasra H Giama Sudhakar K Venkatesh Denise M Harnois Michael R Charlton Hiroyuki Yamada Alicia Algeciras-Schimnich Melissa R Snyder Terry M Therneau Lewis R Roberts 2018World Journal of Gastroenterology2018,24,12:5
