Bilirubin in the Premature: Toxic Waste or Natural Defense?

Bilirubin in the premature: toxic waste or natural defense?

because contamination of the sample by even small volumes of furosemide significantly affected thyroxine results. The differences in sensitivity to furosemide interference among assays appear to reflect the serum dilution used in each method. This concern may apply to interference from other drugs (e.g., salicylates and fenclofenac) as well as to other assays (e.g., free triiodothyronine). This...

Toxic waste disposal in Escherichia coli.

About 10% of the nalidixic acid-resistant (Nal(r)) mutants in a transposition-induced library exhibited a growth factor requirement as the result of cysH, icdA, metE, or purB mutation. Resistance in all of these mutants required a functional AcrAB-TolC efflux pump, but the EmrAB-TolC pump played no obvious role. Transcription of acrAB was increased in each type of Nal(r) mutant. In the icdA and...

Bilirubin binding in premature infants from birth to 3 months.

The effect of postnatal age on serum bilirubin binding measurements was studied prospectively in extremely premature infants of 25-28 weeks' gestation. Serum was obtained from 10 infants at birth, 2-4 days of age, 1 week, 2 weeks, 4 weeks, 8 weeks, and 10-13 weeks. Using peroxidase oxidation, the apparent unbound bilirubin concentration (AUBC) was measured and plotted versus the molar ratio of ...
