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 ...

Analysis of infrared hydroxyl multimer absorbances of dilute solutions of cholesterol in car bon tetrachloride as a function of the monomer absorbance strongly favours the interpretation of the association of this alcohol with a monomer-dimer-tetramer model up to a molar fraction of 0.012. This model also explains very well the concentration dependence of the apparent dipole moment. Equilibrium...

The hemolymph of Sarcophaga peregrina (flesh fly) larvae was found to contain multiple inhibitors of hemocyte cysteine protease. One of them, named sarcocystatin A, was purified and found to be a mixture of the components sarcocystatin A, and AP in a molar ratio of 2:l. These components can exist in either the associated or dissociated form. The apparent heterogeneity of the protease inhibitors...

Anacystis nidulans cultures growing photoautotrophically in a minimal medium were exposed to different concentrations of NaCl, up to 0.4 molar. Initially, a marked decrease in photosynthetic activity took place, which was in direct relation to the salt concentration and which was not associated with a change in endogenous respiratory activity. After a period of exposure to salinity, a process o...

Near-infrared absorption of water and water-benzene mixtures has been measured at temperatures and pressures in the range of subcritical and supercritical condition of water. The molar absorption intensity of the OH stretching overtone transition of neat water was obtained. It decreases linearly with increasing pressure in the region of gas and gaslike density. Enthalpy for dimerization has bee...
