The reduced form of ribonuclease acts on the cells ofEhrlich's carcinoma by producing important changes in the RNA content of cells: (1) First, there is an important synthesis of intracellular RNA and an accumulation of free nucleotides (from the external medium). This phenomenon accompanies the necrosis of the cells. (2) After this first stage begins a(More)
In the present study, we sought to examine the expression of the c-fos proto-oncogene in the cat brain after two different procedures of 24 h sleep deprivation. A first group of cats was gently sleep-deprived; they were awoken by a gentle touch of the hand (n = 5). A second group was sleep-deprived by the water tank technique which is a stressful(More)
Uptake of homologous and heterologous radioactively labelled DNA was studied in ten Streptomyces species. Among these, S. kasugaensis and S. virginiae were shown to take up 0.5-2.0% of the supplied donor DNA at a well-defined point in their growth cycle. The heterologous donor DNA taken up retained its original buoyant density in CsCl gradients. Other(More)
