Definition:

Example Sentences:
(1) If tracer is introduced into the carotid artery after osmotic treatment, brain uptake is increased by a net factor of 50 (a factor of 70 due to elevation of PA, multiplied by 7 due to infusion by the carotid route) as compared to uptake by normal, untreated brain with infusion into a peripheral vein.
(2) Limitations include the facts that the tracer inventory requires a minimal survival period, can only be done postmortem, and has low resolution for cuts of the vagal hepatic branch.
(3) Thus, the enzyme-immunoassay shows specificity and sensitivity comparable to radioimmunoassay making use of radioactive tracer unnecessary.
(4) By contrast, there was a rapid exchange of tracer Leu carbon between placenta and fetus resulting in a significant flux of labeled KIC from placenta to fetus.
(5) Acetylcholine caused a rapid decrease (42% in 1 min) in 36Cl content of control acini which were preloaded with tracer for 12 min, but only a 23% decrease in acini of reserpine-treated rats.
(6) An isotopic steady state was established in five pregnant animals by the daily feeding of a tracer dose of cholesterol-4-(14)C. Comparison of maternal and fetal serum cholesterol SA revealed that an average of 42.6% of the serum cholesterol in the term fetus originated by transfer from the maternal blood.
(7) Injection of the tracer substance wheat germ agglutinin-horseradish peroxidase (WGA-HRP) directly into the basilar pontine nuclei using a ventral surgical approach resulted in the labeling of somata in many areas both rostral and caudal to the basilar pons.
(8) These results suggest that [99mTc]LDL acts as a trapped ligand in vivo and should therefore, be a good tracer for noninvasive quantitative biodistribution studies of LDL.
(9) The organization of the afferent and efferent connections of the sagittal Zones A and B of the cerebellar cortex of the rat have been studied using wheat-germ agglutinin conjugated to horseradish peroxidase as a tracer.
(10) Three exponential terms were required to fit the data for each of the tracers in all six experiments.
(11) The radiation dose to the tumor after a single injection of 500 muCi 131I-MAb 139H2 was 1,300 cGy over 7 days, which appeared slightly lower than the dose calculated after administration of a tracer dose of iodinated MAb 139H2.
(12) A light and electron microscopic double immunostaining technique was employed using the beta subunit of unconjugated cholera toxin as a neural tracer.
(13) Coronary collateral blood flow was measured with tracer microspheres in 3 different experimental conditons in the dog heart: 1. after occlusion of a large coronary artery in the in situ beating heart, 2. after occlusion of a small coronary artery in the in situ beating heart and 3. after occlusion of a large coronary artery in the isolated, empty beating, blood-perfused heart.
(14) This exogenous protein tracer could be seen in apical vacuoles and phagosomes in the cuboidal parietal epithelium.
(15) In the present study, we assessed transepithelial transport of Na+, K+ and Cl- in the isolated initial segment (P1) of rabbit colon in vitro using radioisotopic tracer fluxes and electrophysiological techniques.
(16) Each group of cattle consisted of six permanent members, two members fistulated at the oesophagus and one worm-free tracer calf.
(17) The immunoreactivity of the tracer can instead be lower than that shown by the standard, although it must not be too different.
(18) This reconstruction only requires very general assumptions, such as tracer-tracee indistinguishability and mass conservation; in particular it is independent of the glucose model structure, i.e., number of compartments and their interconnections.
(19) When normalized with respect to scala cross-section, the process of tracer movement across the spiral ligament is similar in the basal and third turns.
(20) The electron-dense tracers, ferritin, peroxidase, Thorotrast, and latex beads were all ingested but none was phagocytized.
