Cell viability under high-temperature stress conditions.

<p>Viability of <i>S. cerevisiae</i> L5685 or L5685<i>Δmac1</i> cells was measured after exposure to high temperature in the presence (100 mM) or absence of NAME. Cell viability was expressed as percentages, calculated as follows: (no. of colonies after exposure to high temperature stress (39°C))/(no. of colonies after exposure to non-stress condition (25°C))×100. The values are the means and standard deviations of at least two independent experiments.
