An abrupt change of some Bragg reflections occurs near the neutral-ionic transition temperature(T
N-I
) in TTF-chloranil. We performed intensity analyses of (3 k l) Bragg refrections below T
N-I
and ...found that donor (TTF

-aldehyde in Thea chloroplasts was clarified with an entire series of synthesized positional isomers, in which the position of cis-1, ...cis-4-pentadiene system varies from C-3 to C-13 in C

-aldehyde is the presence of cis-1, cis-4-pentadiene system between ω-6 and ω-10.
Cultured cells induced from Perilla frutescens leaves were cultured in a 100l jar fermentor, then the Perilla pigment was extracted from the cell cultures as food colors, and examined for their color ...tone, heat and light stabilities and safety. These properties and safety of the pigment from cultured cells were almost similar to those of the pigment from Perilla leaves. Dessert jelly and beverage colored with the pigment suggest that the pigment from cultured cells may be allowed to be used as food colors. However, for practical application of the pigment as food colors, there are still problems to be solved, such as stable productivity of the pigment, residual synthetic phytohormones, metals and salts, and safety.
Fourteen human primary stomach cancer tissues were screened by Southern blot hybridization using six oncogene probes (myc, myb, H-ras, K-ras, abl, mos), and an amplification of c-myc oncogene was ...found in one tissue. This is the first report of c-onc amplification in primary stomach cancer tissue.
Infrared reflectance spectra have been investigated on TTF-chloranil single crystals near the neutral-to-ionic phase transition temperature T
C
. It was confirmed that abrupt changes in the ionicity ...and the stack dimerization take place simultaneously at T
C
. The effect of an external electric field and light irradiation upon the dimerized lattice below T
C
has been investigated by reflectance measurements.
