Through FACS analysis of the cell fluorescence strength the death rates of the cells were measured. The median lethal concentrations of αAFP-RTA, ETA and αAFP + RTA were 6×10-9.6mol/L, 6×10-8.4 mol/L and 6×10-8.2 mol/L respectively.
The fluoride glasses containing alnminum metaphosphate in the system of 60MeF2· (40-X) AlF3·XAl(PO3)3(Me=Mg, Ca, Sr, Ba; X=0-4mol%) have been syntherized. IB spectra as well as physical and chemical properties of the glasses have been investigated.
Kissinger's formula n=1.26S~(1/2). The activation energy is 22.6 Kcal mol~(-1) for a sample with 9.96% oil yield and is 37.2 Kcal mol~(-1) for another sample with 4.16% oil yield. The reaction order for both samples approaches 1.
In order to increase the formation rate of 6-aminopenicillanic (6-APA), this subject designed a proper nanofiltration membrane concentration progress, the average gram molecule yield of 6-APA has reached 90.18% , and n-butyl acetate-alcohol crystallization process was developed.
By plotting the logarithm of rate constants in certain range of temperatures against the reciprocal of the absolute temperature, a linear relationship is obtained. The activation energy of the polycondensation in naphthalene, diphenyl ether, and acetophenone was found to be 17.1, 24.8 and 10.3 kcal/mole respectively.
In this study, we find that prodigiosin could effectively inhibit the proliferation of human pancreatic cancer cells H8898 in a dose-and-time-dependent manner, with an IC50 of 75μmol according to the results of MTT and cell proliferation assays.
Additional ab initio calculations performed at 6-31G** gave a ΔE (Z - E) on the order of 3 kcal/mol.
Roridin P and Isororidin P induced morphological changes in Pyricularia oryzae, with a minimum concentration (MMCC) value of 6.2 ± 1.1?μmol/L and 7.9 ± 1.5?μmol/L.
A sensitive complex absorptive wave of Ca-ARS was obtained by using differential pulse voltammetry when a mercury film glass carbon electrode was immersed in 0.1 mol L-1 KOH and 4.5×10-4 mol L-1 ARS solution.
The peak current was proportional to the concentration of calcium in the range of 5.0×10-8-4.2×10-5 mol L-1.
