抑制作用的

The experimental results indicate that oleic acid has inhibitory effect on the precipitation, and the inhibitory effect is more obvious with increasing addition of oleic acid. Specially, oleic acid of 1×10^(-5) mol/L would facilitate the agglomeration of gibbsite, oleic acid of 1×10^(-4) mol/L would inhibit the agglomeration of gibbsite.

KIR bind corresponding HLA-Ⅰmay hame four results followed:1、When inhibitory KIR bind HLA-Ⅰand there has no activatory KIR bind it,cell isn\'t dissolve because inhibitory signal access was done;2、When activatory KIR bind corresponding HLA-Ⅰand there has no inhibitory KIR bind it,form activate signal,lead cell dissolve.3、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when activatory signal play the main role,NK cell still actived,lead target cell dissolve.4、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when inhibitory signal play the main role,or both signal access don\'t play,NK cell do not make effect.this is NK cell recognice nomal tissue.

与活化型KIR受体相比，抑制型KIR受体与HLA-Ⅰ类抗原结合的亲和性更强，当抑制型和活化型KIR受体识别和结合同一HLA-Ⅰ类抗原分子时，以抑制作用为主。KIR与相应HLA-Ⅰ结合后可能产生以下4种情况：①当抑制型KIR与HLA-Ⅰ结合而无活化型KIR与HLA-Ⅰ相互作用时，因抑制信号通路启动而不产生细胞溶解；②当活化型KIR与靶细胞表面的相应HLA-Ⅰ结合同时无抑制型KIR与HLA-Ⅰ的相互作用时，形成刺激信号通路，导致靶细胞溶解。

S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu. The microorganism inhibition experiment by filter papers indicated that the extract of E. humifusa had higher inhibition effect against bacteria than on pathogenic fungus. Diameters of the zone of inhibition of salmonellas, Echerichia coli and Staphylococcus aureus were 15.77mm, 12.27mm and 10.53mm respectively. The extract of E. humifusa had a certain effect against Colletotrichum lagenarium, Botrytis cinerea, Rhizoctomia solan and Pyricularia oryza but no effect against Helminthosporium maydis and Gibberella zea. The 4 cation exchange resins and ethanol deposition were used to isolate the active fractions from supernate after alkali deposition.

Our research suggests that the cholic acids depress the growth rate of HUVEC with time-concentration dependence.

结论胆酸对HUVEC的生长率有很强的时间-浓度依赖性抑制作用，这种抑制作用除了直接损伤内皮细胞外，还可能与其抑制内皮细胞本身的分泌VEGF有关。

The characteristics of the thermostableα-amylase were also discussed. The optimal temperature and pH for the enzyme were determined as 95℃and 10.0 respectively.

The enzyme activity of PPO showed a decreasing trend with the prolonging of heat-preservation time, which indicated that PPO was a kind of thermal-susceptible enzyme. Three kinds of inhibitors all had inhibitors on the activity of PPO from C. comas. Among them, the inhibition of NaHSO3 was strongest, followed by ascorbic acid and citric acid.

The effect of mineral admixtures on the expansion due to ACR was studied. The results show that the expansion can not be suppressed by natural zeolite, ground blast furnace slag and silica fume, however, it can be suppressed by some kinds of fly ash and the composites of natural zeolite and fly ash, ground blast furnace slag and silica fume respectively.

试验了矿物质掺合料对ACR的抑制作用，沸石、矿渣、硅灰均不能有效地抑制ACR，而某些粉煤灰及沸石与粉煤灰、矿渣、硅灰的复合对ACR有抑制作用。

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.

2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降，但是不同品种/树种的果实软化机理不同，1-MCP抑制其软化的机理也不一致：在红星果实中，对软化起主要作用的酶一直为内切和外切两种PG，而在肥城桃软化过程中，前20d以纤维素酶活性起主要作用，20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降；在肥城桃果实中，1-MCP通过抑制前期纤维素酶和后期内切PG活性，延缓了果实硬度的下降。

And ZNF397nf function as transcription repressors. The different transcriptional regulation activity of the nf isoforms and their interaction with the fu isoforms would contribute to the complexity of the transcription regulation. To further examine the biological function of interaction between different isoforms we also analyze the potential role of ZNF191 and ZNF434 on signaling pathway. We found that ZNF191fu can significantly enhance the HSE-luciferase activity, while ZNF434fu can enhance the AP1-luciferase activity, then we analyze whether the nf isoforms have impact on the fu isoforms.

而这些成员的nf剪接本与它们对应的fu剪接本的转录调控功能有所不同，其中ZNF191nf与ZNF434nf剪接本的转录调控活性相对它们的fu剪接本显著降低，呈现较弱的转录抑制作用，但ZNF447nf剪接本却呈现出显著的转录激活作用，同时ZNF397nf剪接本则表现出显著的转录抑制作用，ZNF396nf剪接本的转录调控作用与其fu剪接本相当。nf剪接本这种与fu剪接本不尽相同的转录调控活性以及能与fu剪接本互作的能力，大大增加了转录调控作用的复杂性，这使得通过少量的转录因子作用来实现众多基因时空表达的不同成为可能。
