Anyone interested in the intracellular/extracellular matrix and/or membrane physiology/biophysics (like me) or just like friggin AWESOME animation need to watch this video.  It explains how leucocytes leave the blood vessels at the right spot at inflammation.

I went to the Octoberfest on the island today after my class, I bought one of those 'German' hats with the feathers, and a drawing of a bird (I dunno what kind, some type of egret I suppose) that looked like Pshaw drew it.  I bought a German cookbook and some German food.  I had a beer because it's fundamentally wrong to attend an Octoberfest and not drink beer.  They were out of shirts though, oh well.  I had stopped before I went home and got some Vietnamese food anyway, and gotten my old wind-up Timex watch fixed.  It's probably the oldest birthday gift I can remember getting, and almost definitely the oldest one I still have.

What impetus does P-selectin have to continiously bind and debind with PSGL-1 ? Is it based on polarisation/depolarisation or is some sort of chemical poential involved?

Bear in mind my biol knowledge is pretty limited - I'm starting my freshman year of biosci next term.

Also, have you seen this?

Yea that's a classic. I don't work with leukocytes or vascular adhesion proteins, but many of them rely on calcium for their binding, and I know that p-selectin has a calcium binding motif so my guess is that it's probably that (at least partially).
