NAPP

New Anticancer Polypeptide ( NAPP ) is a mixture of polypeptide abstracting from deep sea fish .

新生肽是从深海鱼类中提取的一种多肽混合物。

Napp has little cytotoxic effect on target cells and it can effectively inhibit the RNA level of HCV subgenomic replicon cell model .

体外实验Napp对靶细胞安全作用范围较宽，且可有效抑制HCV复制子RNA。

Conclusion : This is an ideal approach to prepare protoporphyrin disodium and NAPP inhibit duplication of Hepatitis B Virus in Vitro .

结论：这是一种较理想的制备NAPP方法，且NAPP可有效抑制HBV-DNA的表达和复制，对靶细胞（肝细胞）无细胞毒作用。

NAG was more accurate than NAPP in predicting acid forming potential of the tailings due to the uncompleted oxidization of pyritic sulfur .

由于黄铁矿硫不会完全被氧化，NAG比NAPP可更为准确地预测尾矿的产酸潜力。

[ Objective ] To explore the improved preparation of protoporphyrin disodium , observe the cytotoxicity of Napp in vitro and its inhibitory effect on HCV subgenomic replicon cell model .

目的本研究对原卟啉钠的制备方法进行了改进，以期简化其生产流程。并且体外观察原卟啉钠的细胞毒性作用及其对HCV亚基因复制子细胞模型RNA的抑制效果。

The NAPP , ANC , NAG of some floatation tailings are determined , and heavy metals releasing after acidification is researched . acid neutralization potential of mine tailings ;

对几种选矿尾矿的净产酸潜力（NAPP）、酸中和能力（ANC）以及净产酸量（NAG）进行测定，考查尾矿酸化后的重金属释放情况。

The acid producing potential of a Pb / Zn mine tailings at Lechang City , Guangdong Province were studied using both net acid generation ( NAG ) and net acid production potential ( NAPP ) methods .

利用净产酸试验（NAG）和净产酸潜力试验（NAPP）方法，研究了广东乐昌铅锌尾矿的产酸潜力。

APP , which can ′ t be dissolved by any solvent under normal temperature , was converted into the sodium polyphosphate ( NaPP ) or sodium-ammonium polyphosphates ( NaAPP ) by ion-exchange method , and then dissolve it in the water .

采用离子交换法把常温下没有溶剂的APP转化成聚磷酸钠（NaPP）或其复盐并溶于水中。
