1气象卫星云图的多分辨小波分解及人工神经网络降水估计研究显示文摘采用多分辨小波分析对卫星图象进行预处理 ,在保留其特征信息的同时 ,减小了数据量 ,改善了神经网络训练过程的收敛性能 ,提高了处理速度。采用这一方法根据 GOES- 8的红外亮温图象和气象雷达资料对巴西圣保罗州中部的降水量估计进行了试验 ,取得了良好的效果。李伟钢 Maria C V Ramirez Nelson J Ferreira 石立华 Leonardo D de A Sá 2000南京气象学院学报2000,23,2:13
2Hepatocellular carcinoma,human immunodeficiency virus and viral hepatitis in the HAART era显示文摘The incidence of hepatocellular carcinoma(HCC)in patients with human immunodeficiency virus(HIV) is rising.HCC in HIV almost invariably occurs in the context of hepatitis C virus(HCV)or hepatitis B virus (HBV)co-infection and,on account of shared modes of transmission,this occurs in more than 33% and 10% of patients with HIV worldwide respectively.It has yet to be clearly established whether HIV directly accelerates HCC pathogenesis or whether the rising incidence is an epiphenomenon of the highly active antiretroviral therapy(HAART)era,wherein the increased longevity of patients with HIV allows long-term complications of viral hepatitis and cirrhosis to develop.Answering this question will have implications for HCC surveillance and the timing of HCV/HBV therapy,which in HIV co-infection presents unique challenges.Once HCC develops,there is growing evidence that HIV co-infection should not preclude conventional therapeutic strategies,including liver transplantation.Douglas C Macdonald Mark Nelson Mark Bower Thomas Powles 2008World Journal of Gastroenterology2008,14,11:9
3Joint effect among p53, CYP1A1, GSTM1 polymorphism combinations and smoking on prostate cancer risk: an exploratory genotype-environment interaction study显示文摘瞄准:与前列腺癌症的调节的人冒的风险的一个环境因素在联合估计几个基因因素的角色。我们集中于与房间控制联系的低外显率的基因的等位基因变体, detoxification 进程并且吸烟。方法:在盒子控制研究,我们比较了与他们的前列腺癌症风险带 p53cd72 职业人员等位基因, CYP1A1 M1 等位基因和 GSTM1 空遗传型的人。结果:为带专业版的吸烟者的联合风险 * 并且 M1 * ,专业版 * 并且 GSTM1null 或 GSTM1 0 和 CYP1A1 M1 * 变体显著地更高(机会比率[或] :13.13, 95% 信心间隔[CI ] :2.41-71.36;或:3.97, 95% CI:1.13-13.95 并且或:6.87, 95% CI:1.68-27.97,分别地) 不为参考组,并且为不抽烟的人与那相比是重要的。或为在 p53cd72, GSTM1 和 CYP1A1 之中的联合,在吸烟者的 M1 断然并且显著地与不抽烟的人相比并且与通常认为的最低风险组相比与前列腺癌症风险被联系(或:8.87, 95% CI:1.25-62.71 ) 。结论:我们的结果建议那在修改前列腺癌症的一个重要角色在学习人口上冒的风险的 p53cd72, CYP1A1, GSTM1 等位基因和吸烟的戏的联合,哪个带易受影响的遗传型的吸烟者可能有的工具显著地更高的风险比带非易受影响的遗传型的那些。Luis A.

4用喷雾法提高哈次木霉1295-22对草坪草病害的生防效果显示文摘哈次木霉(Trichoderma harzianum)1295-22菌株是一种对多种真菌病害具有较好防治效果的生物制剂。研究报道了施用1295-22的颗粒剂和雾剂对匍匐剪股颖的腐霉根腐、褐斑和币斑病的防治效果。研究表明在温室或田间,喷施1295-22的分生孢子悬浮液(SA),都显著减轻了匍匐剪股颖草坪的这3种病害。若在孢子水悬液中添加0.1%的Triton X-100的防治效果更好。若每周都喷洒SA,其防治效果相当于常规杀菌剂。撒施颗粒剂(GA)也能显著减轻根腐病、币斑病和褐斑病的叶部症状,草坪质量也有所提高。用1295-22的SA或GA处理过的剪股颖根区的木霉菌(Trichoderma spp.)群体比未处理的提高了10~100倍,但是仅在喷施SA之后,1295-22才以高水平存在。总之,1295-22在根围和叶围都有较强的竞争力。在使用颗粒剂之后再喷施分生孢子悬浮液可减轻根部和叶部病害。Lo C T Nelson E B 朱廷恒 1999国外畜牧学(草原与牧草)1999,,2:4
