guanosine/옥수수

Gas chromatographic-mass spectroscopic evidence is presented for the presence of guanosine-3': 5'-monophosphate (cGMP) in maize seedlings. The amount of cGMP (35-72 pmol g(-1) fresh weight) was quantified as a tetra-silyl derivative using gas-chromatographic detection with reference to a silylated

Our earlier work has shown a selective promotional effect on the genesis of mammary carcinomas bearing a wild-type, but not mutant, Ha-ras codon 12 in a 1-methyl-1-nitrosourea (MNU)-induced carcinogenesis model by high-fat diets (Nutr Cancer 23, 283-290, 1995). To test the hypothesis that activation

Prior experiments illustrated reactive oxygen species (ROS) overproduction in maize plants infested with bird-cherry-oat (Rhopalosiphum padi L.) aphids. However, there is no available data unveiling the impact of aphids feeding on oxidative damages of crucial macromolecules in maize tissues.

Microsomal membrane preparations from maize (Zea mays L., inbred A636) endosperm cultures contained enzymes that transferred sugar moieties from uridine diphosphate-N-acetylglucosamine, guanosine diphosphate-mannose, and uridine diphosphate-glucose to dolichol-phosphate. These enzyme activities were

When green leaves of spinach (Spinacia oleracea L.) were surveyed for the presence of hexokinases which utilize glucose, fructose and-or mannose as a substrate, four kinases could be distinguished by their order of elution during chromatography on diethylaminoethyl (DEAE)-cellulose: (i) a hexokinase

Tocompare the effect of folic acid (FA) and α-naphthoflavone on 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cleft palate in fetal mice. Pregnant mice were randomly divided into seven groups. The mice treated with corn oil were used as a negative control. The mice in the other six groups were

Estrogen (17beta-estradiol, or E2) reduces systolic blood pressure (SBP) increment and increases aortic cyclic guanosine monophosphate (cGMP) in male spontaneously hypertensive rats (SHRs). It is unknown, however, whether the E2-enhanced aortic cGMP is essential for the BP-lowering effect or not.

The effects on energy balance and brown adipose tissue thermogenesis of feeding high fat diets of differing fatty acid composition have been investigated in lean and genetically obese (ob/ob) mice. Groups of mice were fed either a low fat diet or a high fat diet based on corn oil or beef tallow for

We have demonstrated that diets containing fish oil and pectin (FO/P) reduce colon tumor incidence relative to control (corn oil and cellulose [CO/C]) in part by inducing apoptosis of DNA-damaged colon cells. Relative to FO/P, CO/C promotes colonocyte expression of the antiapoptotic modulator,
