Pyrimidine Derivatives and Purine Bases in Soils
In earlier papers the presence of protein decomposition products in soils was reported and it was shown that in soils the changes occurring in the decay of such plant and animal materials as get into the soil are similar to the changes occuring under other conditions in the laboratory or in nature. The presence of arginine and histidine in soils was definitely established by isolating these deg...

متن کاملActivation of respiratory complex II by interferon-gamma and its inhibition by pyrimidine derivatives.
OBJECTIVES Formation of formazan is a commonly used measure of cytotoxicity of compounds. It is a product of reduction of tetrazolium salts such as 4-[3- (4-iodophenyl)-2- (4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate (WST-1) and 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride. The extent of substrates reduction reflects the activity of enzymes succinate dehydrogenase...

cus aureus by heat shock. The effect has then been more thoroughly investigated by landolo and Ordal (5, 6). Since heat shock causes an increased sensitivity of fungal cells to high temperature and blue light (2-4), it seemed justified also to test the response of heat-shocked fungal cells to high concentrations of sodium chloride. Most experiments were performed with the ascomycete Ophiostoma ...
