In this passage, Trillin exposes the immeasurable distance between the civil-rights icon and the entrenched thinking of the old South: Across the aisle from King, there happened to be sitting a stocky, nice-looking young white man with a short haircut and wearing Ivy League clothes….
Little did I grasp then that enthusiastically participating in this sunny rite of passage would expose me to its depressing shadow side.
Our nasal passages are exposed to a lot of abuse from pollution to viruses and the neurons within them die and are reborn constantly.

D2 NSCs (72 h after passaging) were exposed to 3 μM DMNQ for up to 24 h.
Cells were allowed to recover, and when the surviving populations reached 80% confluence, cells were passaged and exposed to oxaliplatin again for 48 h.
One set, termed "stress passaged," was exposed immediately after being restruck to 1 hr at 4° and then one hour at 37° prior to incubation at 30° every three passages.
There is evidence, however, that extensive in vitro passages could expose MSC to mutations, and in principle the possibility that MSC could produce tumours when transferred in vivo, as demonstrated in mice [ 104].
The profound and complex nature of the airborne exposures at the WTC site, coupled with early reports of inflammation in the upper respiratory tract and the nasal passages in exposed individuals, led us to hypothesize that olfactory acuity would be decreased but that trigeminal sensitivity might be increased or decreased in this group.
The chronic model of oxidative stress was induced in cultured normal fibroblasts by perturbation of the glutathione redox cycle {cells were serially passaged while exposed to regular treatment with 10 μM L-buthionine-[S,R]-sulphoximine (BSO), an inhibitor of glutathione synthesis} (Kurz et al., 2004).
