A new method is presented for twist mounting insect pins onto standard dissecting (teasing) needles. Insect pins, with their sharp points, are ideal for fine dissection of plants, especially of shoot tips and early developing flower buds. T...
Theory of cathode trajectory characterization by canonical mapping transformation [0.03%]
基于典范映射变换的阴极轨迹理论研究

Shin Fujita
The paraxial lens theory cannot directly be applied to the cathode trajectories inside the gun. This inconvenience makes the interpretation of cathode trajectories difficult since one cannot use the physical concepts familiar in the paraxia...
Guanine is indispensable for immunoglobulin switch region RNA-DNA hybrid formation [0.03%]
鸟嘌呤对于免疫球蛋白转换区RNA-DNA杂交体的形成是必不可少的

Ryushin Mizuta
It is suggested that the formation of the switch (S) region RNA-DNA hybrid and the subsequent generation of higher-order chromatin structures including R-loop initiate a class switch recombination of the immunoglobulin gene. The primary fac...
Characterization of the degradation of recombinant rat urate oxidase in tetracycline controlled gene expression cells [0.03%]
