3.A derivative-free noncircular fan-beam reconstruction formula was brought forward by Ge Wang,,Tein-Hsiang Lin and Ping-chin Cheng. And they proved that the formula was accurate under the condition that the three assumptions were satisfied.
资料WANG Ge等人在《A Derivative-Free Noncircular Fan-Beam Reconstruction Formula》中提出了一个不含源到中心距离导数的重建公式,并证明在满足三个假设的条件下该公式是一个准确重建公式。
4.Genetic analysis was carried out on reproduction traits in large white sows both in Zhenghong and Yinong swine breeding farm in Hunan Province. Multiple traits derivative free Restricted maximum likelihood(MTDFREML) were used to estimate 7 736 records from the year of 1998 to 2004,including total number born(TNB),number born alive(NBA),litter weight born(LWB) and litter weight of 21 days(LW21).
运用多性状非求导约束最大似然法(multiple traits derivative free restricted maximum likelihood,MTDFREML),对湖南正虹种猪场和益阳市农科所种猪场(益农种猪场)大白母猪1998-2004年的共7 736胎次的繁殖性状育种记录进行遗传参数估计.
5.Objectives: To evaluate the lethal effect of hepatoprophyrin derivative(HpD) mediated photodynamic therapy (PDT) on cultured C6 glioma cells so as to provide the further evidence for the clinical application of the technique. Methods: This study consists of two parts. Part one: Examination of cell survival rate and structure of C6 glioma cells after different HpD-PDT treatment:
目的:分析应用国产血卟啉衍生物(Hematoporphyrin Derivative,HpD)的光动力学疗法(Photodynamic Therapy,PDT)对体外培养大鼠C6胶质瘤细胞的杀伤效应,为临床PDT治疗脑胶质瘤提供实验依据。
6.Objective To investigate the effects of hematoporphyrin derivative(HPD) in different concentrations on photodynamic therapy for human esophageal cancer cell line Eca-109 in vitro at various time points.
目的:探讨血卟啉衍生物(hematoporphyrin derivative,HPD)孵育浓度和孵育时间对人食管癌细胞Eca-109体外光动力疗法(photodynamic therapy,PDT)效应的影响。
7.The results indicated that after the 1,4-DHP derivative interacts with CT-DNA,the intensity of the fluorescence peak of the 1,4-DHP derivative is increased,illustrating that the 1,4-DHP derivative is intercalated into CT-DNA. If the intensity of the fluorescence peak of 1,4-DHP derivative is decreased,the interaction between the 1,4-DHP derivative and CT-DNA is not in the intercalation mode.
结果表明,1,4-DHP衍生物分子与CT-DNA相互作用后,如其荧光显著增强,表明1,4-DHP衍生物分子嵌入到CT-DNA中,如荧光明显减弱,表明1,4-DHP衍生物分子不是以嵌入模式与CT-DNA相互作用。
8.RESULTS:①After co-culture of hematoporphyrin derivative and CNE2 cells,irradiation with isemiconductor laser at 630 nm could kill the CNE2 cells. The killing effect was positively correlated with the concentration of hematoporphyrin derivative and the dosage of radiation(P < 0.01),but it did not increased obviously when the concentration of hematoporphyrin derivative was over 2.5 mg/L.
结果:①血卟啉衍生物与CNE2细胞共同孵育后,采用630nm的半导体激光照射可对其产生杀伤作用,杀伤作用大小与血卟啉衍生物的浓度和激光剂量成正相关(P
