查询词典 descending induction

The 'permanent truth' is close to Russell's 'apriority' of induction. However, in my opinion, this kind of permanent truth or apriority doesn't have any important sense since the principle of anti-induction, i.e.,'if at1—btb,……,atn—btn then probably AB', has the same property.

这种"永真性"与罗素关于归纳原则的"先验性"十分接近，然而，在笔者看来，这样的永真性和先验性没有多大意义，因为反归纳原则即"如果at1—btb，……，atn—btn则大概AB"也具有这样的性质。

The results are as follows: 37℃ is the most favorable temperature for induction expression of SUMO-hEGF in BL21, 5.0g/L the most best concentration of arabinose, and 4h the best time for induction expression. Meanwhile, the quantity of expression is around 20.2%. The conclusion that hEGF is the purified protein is verified by Western blotting. It is a good foundation for the development of hEGF genetic medicine.

The results showed that in undifferentiated P19 cells, Tra2β1 increased the Flop splicing of GluR-B and BEK splicing of FGF-2R. At the neuronal dominant stage of differentiated P19 (at 9d after RA induction), Tra2β1 increased the Flop splicing of GluR-B, but had no obvious effects on the splicing of FGF-2R. At the glial dominant stage (at 13d after RA induction), Tra2β1 increased the Flop splicing of GluR-B, but had obvious inhibitory effects on the splicing of FGF-2R.

结果表明，在未分化的P19细胞中，Tra2β1能增强GluR-B的Flop剪辑和FGF-2R的BEK剪辑；在P19分化至神经元为主的阶段（RA诱导后第9天），Tra2β1明显增强GluR-B的Flop剪辑，而对FGF-2R的BEK剪辑无明显影响。P19分化至胶质细胞为主的阶段（RA诱导后第13天），Tra2β1明显增强GluR-B的Flop剪辑，但对FGF-2R的剪辑有明显抑制。

Results Nine days after ulcer induction, the ulcer area was 11.9±3.1mm^2 and 19.7±3.8mm^2 in rats with normal saline and celecoxib treatments, respectively (P.01). The total acidity of gastric juice and the expressions of H(superscript +), K(superscript +)-ATPase mRNA and protein in celecoxib group were significantly higher than that in normal saline group at both 6 and 9 days after ulcer induction, but no significant difference was found between the two groups in the amount of secretary canaliculus and microvillus.
