This report describes a micro-clot lysis assay (MCLA) for evaluating fibrinolytic activity of plasminogen activators (PA). Fibrin clots were formed in wells of microtiter plates. Lysis of the clots by PA, indicated by change in turbidity (optical den

Irreversible loss of the ability to develop chloroplasts in Euglena gracilis may develop following transfer from organic medium to defined medium. Requirements for the loss include the absence of light and a temperature of 30 C (the optimal temperatu

The current radiation protection guidelines of the National Aeronautics and Space Administration (NASA) were recommended in 1970. The career limit was set at 4.0 Sv (400 rem). Using the same approach as in 1970 but current risk estimates, a considera

Hydroxyurea (10 mM) arrests the exponential growth of Tetrahymena by blocking DNA replication during S-phase. After removal of the hydroxyurea (HU), they have a long recovery period during which they are active in DNA synthesis. 3H-TdR uptake showed
