Phenylhydrazine interacted with oxidized and reduced cytochrome P-450 of rat liver microsomes to produce binding difference spectra typical of many nitrogenous compounds. The phenylhydrazine-induced difference spectrum observed with oxidized microsomal cytochrome P-450 was converted, in a time-dependent process, t o yield a new spectral intermediate with an absorbance maximum around 480 nm. ...

The administration of cobalt to rats caused a marked increase in the oxidative degradation of heme (hematin, iron protoporphyrin-IX) by hepatic microsomal enzymes. The onset of this enzyme stimulation was very rapid, beginning within 2 hours after injection of the metal and reaching its maximum in 16 to 24 hours. During the rapid phase of stimulation, i.e. the first 2 to 4 hours, when heme oxid...

Although distinctions between full-time and part-time work are vital for understanding inequalities at home, consensus critical reflection lacking in how employment status should be defined. Full-time often represented as a binary split those working under or over specific number of hours. However, this paper, using exploratory mixed methods, evidences problems with assumptions based on working...

Abstract This research is motivated by the behavior in community that preserves fish meat using a dangerous chemical substance, namely formalin. Research has been carried out on detection of formalin 450 nm light-based laser photoacoustic imaging tool to characterize image system detect meat, determining relationship average sound intensity obtained, as well differences tomography images concen...

This experimental study investigated the effects of quenching and tempering heat treatment on fatigue behavior and also tempering temperature and time holding of AISI 1060 steel. At first, the specimens were austenitized at 800˚C for 1 hour, and then were quenched in the water bath of 25˚C temperature. After that, tempering process was done at the temperature of 250˚C, 450˚C and 650˚C for 1 and...
