水杨酸和多效唑对玉簪叶片生理生化的影响

为研究水杨酸(SA)和多效唑(PP333)对玉簪叶片生理变化的影响，本实验以玉簪(Hostu pluntagineu Aschrs)和狭叶玉簪(H．luncifoliu Engler)为试材，用SA和PR33处理玉簪叶片。结果表明：经过这两种生长抑制物质处理后，玉簪叶片的叶绿素含量、类胡萝卜素含量和过氧化氢酶活性都有显著提高；而经水杨酸处理后可溶性蛋白含量有所下降，经多效唑处理后含量有所增加。     

小波神经网络应用于色谱信号处理中的一种改进算法

在紧致集正交小波神经网络对色谱信号处理应用的基础上,提出一种新的算法,即用B-样条函数代替紧致集正交小波函数,这样便可以解决难构造出具有解析形式的紧致集正交小波函数的问题.这种方法的引入可以使神经网络在信号的处理范畴中得到更广泛的应用.     

Assembling Zwitterionic, Water-Soluble Porphyrin and Its Biological Studies

A kind of zwitterionic water-soluble porphyrin 5-(N-trimethyl-4-aminiumphenyl)-10, 15, 20-tri (4-sulfonatephenyl) porphyrin trisammonium salt, has been synthesized. Its biological studies, interactions with DNA and bacteria cells, were investigated. The damage to the cell wall of bacteria E. coli were observed firstly by AFM (Atomic Force Microscope).     

Initiating, growing and cracking of hydrogen blisters

The growing process of a hydrogen blister in a wheel steel was observed in situ with an optical microscope, and the fracture surfaces formed from broken blisters on a wheel steel and bulk metallic glass were investigated. The initiating, growing, cracking and breaking of hydrogen blisters are as follows. Supersaturated vacancies can increase greatly during charging and gather together into a vacancy cluster （small cavity）. Hydrogen atoms become hydrogen molecules in the vacancy cluster and hydrogen molecules can stabilize the vacancy cluster. The small cavity becomes the nucleus of hydrogen blister. The blister will grow with entering of vacancies and hydrogen atoms. With increasing hydrogen pressure, plastic deformation occurs first, the hydrogen blister near the surface extrudes, and then cracks initiate along the wall of the blister with further increasing hydrogen pressure. A cracked blister can grow further through propagating of cracks until it breaks.     

Crocin Synthesis Mechanism in Crocus sativus

Saffron （Crocus sativus） cells can synthesize crocin, crocetin digentiobiosyl ester, in suspension cultures. The crocin family biosynthesis mechanism was studied using high pressure liquid chromatography （HPLC） to determinate the glucosyltransferase activity and to develop a method for synthesizing medicine from saffron cells. Previous studies indicated that two glucosyltransferases might be involved in the formation of crocetin glucosyl- and gentiobiosyl-esters. GTasel formed an ester bond between crocetin carboxyl groups and glucose moieties while GTase2 catalyzed the formation of glucosidic bonds with glucosyl ester groups at both ends of the molecule. These enzymes can catalyze the formation of crocetin glucosides in vitro. GTasel activity is higher during the first four days of crocin glucosides biosynthesis, but decreases after four days. The formation and accumulation of crocin increase during the first six days and stabilized on the eighth day.
