In cell cultures previously treated with homologous interferon, the magnitude of antiviral activity and the degree of stimulation of aryl hydrocarbon hydroxylase induction appear to be directly related. In a highly purified mouse interferon preparation, the factor stimulating hydroxylase induction and the factor directing antiviral activity are inactivated by heating to 70 C or by treating with...

human conjunctiva cell cultures. Following treatment with mithramycin, RNA synthesis was decreased by 85% in mouse embryo and BHK-21 cell cultures and by 45% in human conjunctiva cell cultures when compared to controls. The inhibition of RNA synthesis in BHK-21 cells was dosedependent and encompassed all cellular types of RNA. Although mithramycin inhibited protein and DNA syntheses in BHK-21 c...

The authors would like to correct Fig 1, as errors were introduced in the preparation of this figure for publication. In Fig 1B, the bld2-6; BLD2 panel and the pf15-1; PF15HA panel are duplicates. The authors regrew the cell cultures in these panels, as well as the parental strains shown in the same panels of Fig 1A, and they have provided a corrected version of Fig 1 here.

The rates of ethylene production per unit mass of Mucor hiemalis are highest at low specific growth rates. Thus this fungus probably produces more ethylene in the soil, where growth rates are low, than would have been predicted by laboratory batch culture, where growth rates are high. The rate of utilization of energyyielding substrate by Mucor hiemalisincreases logarithmically with growth rate...
