N/A, not applicable (a zero Neumann condition was used instead of Eq. 12); Ox-LDL, oxidized low-density lipoprotein.

^*Specifically, $f\left(x,y,t\right)={\displaystyle {\sum }_{k=1}^N{f}_k\left(t\right)}\exp \left[-a_k{\left(x-x_k\right)}^2-b_k{\left(y-y_k\right)}^2\right]$ for some constants a_k, b_k, N, x_k, and y_k and time-dependent functions f_k(t).
