Characterization of temperature-sensitive mutants of bacteriophage PM2: membrane mutants. | In an effort to understand the genetic regulation of membrane morphogenesis, twenty-nine temperature-sensitive mutants of the membrane-containing bacteriophage PM2 were isolated. Characterization at restrictive temperature revealed groups showing no lysis (Groups I--IV), partial lysis (Groups V--VIII), and full lysis (... | 739,979 | [

Methaemoglobinemia induced by nitric oxide in whole blood. Quantitative relationship. | We studied in vitro the effects of nitric oxide (NO) in human and rat blood and in human erythrolysate. Using NO in the tonometric technique allows to predict through an experimental model the amount of methemoglobin formed. At known oxygen and carbon dioxide pressures, methaemoglobinemia is all the more important as N... | 741,469 | [
