Visual stimulation with precise control of stimulus has transformed the field of psychophysics since the introduction of personal computers. Luminance and chromatic features of stimulus, timing, and position of the stimulus are the main features that could be defined using programs written specifically for psychophysical experiments. In this manuscript, software used for the psychophysical expe...

Since its discovery in 1979, the role of the p53 protein in cancer has been studied intensively (Levine and Oren, 2009). p53 is a crucial tumor suppressor, long-recognized to suppress cancer through the induction of cell-cycle-arrest or apoptosis programs in response to a plethora of different cellular stress signals. Although this model paints a seemingly simple picture, the longer that p53 is...
