A NIOSH-certified CBRN full-face-piece SCBA operated in a. While a minimum lethal concentration of 80 mgL is rather well-supported to date 2627100 there is some evidence that there may be susceptible individuals who experience serious toxicity and lethality even below a concentration of 80 mgL 27.

A rise in concentration of Cln3 protein during G1 phase was also detected in a previous study that used. The finding that a greater than 10-fold increase in Whi5 protein levels does not cause a lethal cell cycle arrest or a massive increase in cell size indicates that there must be dilution-independent mechanisms for overcoming Whi5 inhibition. Finally the Whi5 dilution model cannot.
