To assess the biological markers of benzene exposure, unmetabolized
benzene excreted in the urine, or 2 of its metabolites, i.e., S-phenylmercapturic acid (S-PMA) or trans,trans-muconic acid (t,t-MA), were determined .
Anthocyanin glycosides from berry fruit are absorbed and excreted unmetabolized
by both humans and rats.
The human organism does not produce any enzyme that hydrolyzes FOS, so these compounds cross the digestive tract unmetabolized
, providing low energy levels.
They are detected mainly as unmetabolized
glycosides in plasma and in urine, rather than as aglycones.
There are a number of ways for antibiotics used in agriculture to pollute the environment: spillover in the manufacturing process, atmospheric dispersal of treated feed, and unmetabolized
antibiotics in animal waste used to fertilize crops.
Arsenobetaine, an unmetabolized
form of arsenic found in fish and seafood, is considered nontoxic (Francesconi et al.
Vitamins B6 and B12 Decrease the Concentration of Unmetabolized
They bind strongly to HA crystals and are retained for a long time in bone, eventually excreted unmetabolized
Studies have shown that more than 75% of an initial dose of buprenorphine is excreted unmetabolized
within one week .
ATP is first incubated with P-gp; then the P-gp ATPase reaction is stopped, and the remaining unmetabolized
ATP is detected as a luciferase-generated luminescent signal.
Instead of projections being contained by being metabolized, therapists and participants are faced with unmetabolized
anxieties and resort to defending against these uncomfortable and overwhelming feelings by engaging in enactments.
Given the high residue concentrations in mature, unmetabolized
tetracycline residues may also affect the dissemination of Stx phages in cattle manure.
