The smdy of tissue protein breakdown in vivo is difficult, because amino acids released during intracellular breakdown of proteins can be extensively reutilized for protein synthesis within the cell, or the amino acids may be transported to other organs where they enter anabohc pathways. However, actin and myosin are methylated by a posttranslational reaction, forming d-methylliistidine. During intracellular breakdown of actin and myosin, 3-methylhistidine is released and excreted into the urine. The urinary output of the methylated amino acid provides a rehable index of the rate of myofibrillar protein breakdown in the musculature of human subjects. [Pg.576]

Erythrocyte NAD falls during niacin depletion and rises during repletion in human subjects. Erythrocyte NADP is unaffected, and the ratio of NADiNADP provides a useful index of niacin nutritional stams, with a ratio <1.0 indicating deficiency (Fu et al., 1989). [Pg.226]

A great many alkaloids have been found to possess uterine stimulating properties. It is unfortunate that so few of them are therapeutically useful drugs. However, those that are clinically important are very effective d ugs and, when employed judiciously, are extremely valuable therapeutic agents. The usefulness of a drug is determined by manj factors, such as, the rate of its absorption and elimination its diffusibility the rapidity and persistence of its action its side effects and therapeutic index. Tftese aspects of its pharmacology can only be studied, of course, in the intact animal, and preferably in the human subject. In this connection, it should be pointed out that the uterine actions of the majority of... [Pg.200]

The inhibition in brain AChE activity is the crucial facet of the neuroloxic effects of anti-ChEs in rodents and other test species, but such a measurement is obviously impossible to make in human subjects and indirect mcthod.s must be utilized. The inhibition in scrum or plasma ChE activity is often used as a index of potential inhibition in brain AChE activity in humans who may be exposed to anti-ChE. In the rat exposed to DFP. a significant hypothermic response was associated with an inhibition in serum ChE activity of 54% (Gordon and Fogelson, 1993), With other OPs, plasma or scrum ChE activity can plummet to below 25% of normal before there is a significant hypothermic effect. A 5-min exposure to vapors of DFP in the mouse causes core temperature to decrease by mure than 4 C within 30 min and remains depressed for approximately 4 hr (Scimeca et al., 1985). This was associated with a 66% inhibition in brain AChE activity that remained depressed despite a full recovery in core temperature and motor coordination. [Pg.556]

In addition to the traditional human conceptual or subjective judgments or similarity, data can be an objective similarity measure (the difference in weight between a pair of animals) or an index calculated from multivariate data (the... [Pg.947]

The third edition contains major improvements over the previous two editions. I have updated references. Each reaction is now supplemented with two to three representative examples in synthesis to showcase its synthetic utility. As Emil Fischer stated Science is not an abstraction but as a product of human endeavor it is inseparably bound up in its development with the personalities and fortunes of those who dedicate themselves to it. To that end, I added biographical sketches for most of the chemists who discovered or developed those name reactions. Furthemore, I have significantly beefed up the subject index to help the reader navigate the book more easily. [Pg.660]

The taste sensor will be applicable for quality control in food industry and help automation of the production. The sense of taste is vague and largely depends on subjective factors of human feelings. If we compare the standard index measured by means of the taste sensor with the sensory evaluation, we will be able to assess taste objectively. Moreover, the mechanism of information processing of taste in the brain as well as the reception at taste cells will also be clarified by developing a taste sensor which has output similar to that of the biological gustatory system. [Pg.399]

In human studies, flaxseed consumption has had positive impacts on carcinogenesis and parallel observations from animal studies. A doubleblind, placebo-controlled, prospective clinical trial involving 39 women, newly diagnosed with breast tumors, was completed to evaluate the effect of flaxseed consumption on tumor growth (Thompson et al., 2000). Subjects given flaxseed (25 g/day) diets had reduced tumor cell proliferation and c-erB-2 expression, and an increased apoptosis index compared with women who ate whole-wheat muffins. [Pg.34]

Figure 9 Effect of cyclosporin A on the brain (A) and plasma (B) concentration of nC verapamil in healthy volunteers. (A) 1 -Verapamil ( 0.2 mCi/kg) was administered to healthy volunteers intravenously, approximately one minute before and after one-hour infusion of cyclosporin A (2.5 mg/kg/h). (B) PET images of a normal human brain after nC-verapamil administration in the absence or presence of cyclosporin A. Images shown are in SUV summed over a period of 5 to 25 minutes, which is an index of regional radioactivity uptake normalized to the administered dose and weight of the subject. Abbreviations PET, positron emission tomography SUV, standardized uptake value. Source From Ref. 218.
