Inhibition total

The extent of inhibition of the oxidation of peroxidase substrates by ferulic salts was quite variable, from no inhibition to total inhibition. Total inhibition occurred when the substrate (e.g., syringaldazine) was closely related to ferulic acid. The presence of a fluorine atom in ferulic acid slightly reduced the inhibitory effect. Oxidation of ferulic compounds was restricted to lignifying cell walls in situ. Cell wall peroxidases from bark and xylem were fractionated into their component isozymes. 

Two metrics were used to quantify inhibition total consumed glucose and consumption rate. Figures 1-3 show average values derived from replicate samples within single experiments. 

By the use of radioactively labelled precursor chemicals, the cell s ability to synthesize macromolecules such as DNA, RNA, and proteins, after treatment with the drug, can be measured. A typical result is shown in Fig. 5, for exposure of the cells to the equivalent level of drug found in tumor tissue of a treated animal. The synthesis of new total DNA is selectively and persistently inhibited. Total RNA and protein syntheses are not markedly affected until much higher drug-dose levels, which are frankly toxic to... 

Continuous feeding of rats with 1% fenugreek seed powder (FSP) and 0.05% and 0.10% diosgenin suppressed total colonic aberrant crypt foci (ACF) by up to 32, 24 and 42%, respectively, in azoxymethane-induced carcinogenesis in rats. During the promotional stages, FSP inhibited total ACF. 

In 75 days old rye plants, a DIBOA concentration of 128 to 423 pg / g dry weight was determined. 35- Day old rye has a potential to release 14.3 kg / ha of DIBOA [169]. Even a release of 16.2 kg DIBOA / ha from 34 day old rye was reported [170]. Fresh rye mulch containing 20 - 50 mmol / ha hydroxamic acid had only half of this concentration after 12 days, and after 121 -168 days the compound was not detectable anymore [62]. Longer lasting phytotoxic effects of the mulch should be due to the more stable decomposition product BOA. It was foimd that fall-killed Balboa rye suppressed weed biomass by 84 % compared to controls [163]. Fall planted spring killed rye mulch was able to inhibit total weed biomass by 68 -95 % [164]. Similar results were reported using rye mulch in no-till cropping systems [174]. 

Phenidone (l-phenyl-3-pyrazolidone) inhibited total volatile oil yield in wheat by 43%, which was the largest decrease we found (Table V). Nordihydroguaiaretic acid, an aromatic polyphenol caused a 32% inhibition in total volatile oil yield. Acetylsalicylic acid, on the other hand, did not affect yields. Acetylsallcylic acid is a strong inhibitor of cyclooxygenase but a weak inhibitor of lipoxygenase (28). On the basis of these...

From Table 2, it seems that the stage of leaf development influences more than just total rubisco activity. The basal section of the rice leaf, which was nearest the meristem, had the lowest total rubisco activity, and the least dark inhibition. Total rubisco activity, and the...

Although hypophysectomized rats contain more arachidonic acid than normal, co-9 eicosatrienoic acid is also found. Prostaglandin formation in the EFA-deficient rat is severely impaired, and cu-9 eicosatrienoic acid is a potent inhibitor. This suggested that in the hypophysectomized rat similarly, prostaglandin synthesis was inhibited. Total body prostaglandin synthesis was monitored by measuring excretion of prostaglandin metabolites in the urine (Table 2.6). In the rat derivatives of tetranorprostane dioic acid are found in...
