TLDR
The results suggest that liver purine metabolism might participate in the maintenance and renewal of the blood purine pool and in the energy state of erythrocytes in vivo.About:

Anticipatory changes in liver metabolism and entrainment of insulin, glucagon, and corticosterone in food-restricted rats.
TL;DR: Variations detected in the liver of food-restricted rats are different from those prevailing under 24-h fasting, which suggest "anticipatory activity" of the liver metabolism to optimize the processing of nutrients to daily feeding.

Day-night variations of adenosine and its metabolizing enzymes in the brain cortex of the rat--possible physiological significance for the energetic homeostasis and the sleep-wake cycle.

TL;DR: It is suggested that adenosine in the brain cortex of the rat can participate at least in two physiological processes: regulation of the sleep-wake cycle and replenishment of the adenine nucleotide pool.
Journal ArticleDOI
Effect of adenosine analogues and cAMP-raising agents on TNF-, GM-CSF-, and chemotactic peptide-induced degranulation in single adherent neutrophils.
TL;DR: Adenosine appears to be an effective inhibitor of neutrophil granule protein secretion induced by fMLP but only a weak inhibitor of exocytosis in response to TNF or GM‐CSF.
Journal ArticleDOI
Day-night cycle of lipid peroxidation in rat cerebral cortex and their relationship to the glutathione cycle and superoxide dismutase activity
TL;DR: It is proposed that fluctuations in lipoperoxidation, glutathione cycle components and superoxide dismutase activity could act as a physiological oscillator with an important role in modulating the membrane properties of the nerve cell.
Journal ArticleDOI
Circadian variations of adenosine and of its metabolism. Could adenosine be a molecular oscillator for circadian rhythms
TL;DR: The biological implications of the periodic changes of adenosine concentrations in different tissues of the rat are described and the rhythmicity of this molecule, as well as its metabolism and even the presence of specific receptors, suggests a regulatory role in eukaryotic cells and in multicellular organisms.

A method for the colorimetric determination of phosphorus.
TL;DR: A method is described for the colorimetric determination of phosphorus, using ferrous sulfate as a reducing agent, and it is suggested that this method may be useful in the determination of phosphorous hardness.

Rapid specific method for determination of aldosaccharides in body fluids.
TL;DR: A coupling reaction was worked out utilizing the conjugation of aldoses and ketoses with meta-aminophenol in acetic acid to avoid the non-specific reduction methods for glucose determinations.
