background: hypoxemia is a frequent complication after general anesthesia. it usually takes longer to recover in individuals with respiratory problems. bakers may suffer from respiratory problems such as asthma. the objective of this study was to compare the occurrence of hypoxemia and duration of supplemental oxygen administration during recovery from general anesthesia in bakers and smokers. ...

Cannata and Stoppani (1, 2) found that bakers’ yeast contains an adenosine diphosphate-dependent phosphoenolpyruvate carboxykinase, and they ascribed the essential physiological role of oxaloacetate synthesis to it. Doubts concerning their interpretation arose, however, when it was revealed (3, 4) that cellfree preparations of the same microorganism could catalyze the direct carboxylation of py...

1. Despite the same methionine-sulfur:heme-iron:imidazole-nitrogen hemochrome structure observed by x-ray crystallography in four of the seven c-type eukaryotic and prokaryotic cytochromes examined, and the occurrence of the characteristic 695 nm absorption band correlated with the presence of a methionine-sulfur:heme-iron axial ligand in all seven proteins, they fall into two distinct classes...

In previous papers we have described methods for accurately measuring the spectra that represent the differences between the oxidized and the reduced forms of the cytochrome components of the turbid heart muscle particles that contain the intact succinic oxidase system (1, 2). In order to extend the pioneer observations of Keilin and Hartree on the carbon monoxide compound of cytochrome a3 (3) ...
