I like to think of opsinization as "honey" that makes the target pathogen more delicious to phagocytes. Visual: bees to honey. "Bee"-cells respond, make honey, to attract "b"ears to eat them.

@fullmetalsnowflake2508 8 лет назад

+Debi Baird hahaha I love it. Great mnemonic!

@rgnap 6 лет назад

We had a Greek girl in my med school class that says opsonise comes from a greek word meaning 'to make something tasty'. Haven't forgotten it since!

@pedroparamo4938 5 лет назад

@flogurl9 12 лет назад

I don't know why professors have to be so sneaky by omitting info and assuming that we'll somehow figure it out with the hundreds of notes that we have to study. You sound more passionate about what you're teaching than any professor I've known in medicine. Thank you.

@bubbl3z94 12 лет назад

@democolor42 10 лет назад

Really enjoy of these videos, he interprets everything so well

@amandarios448 4 года назад

I like that he explains the meaning of the words and everything. Of you just spit out a bunch of names & deliver it in a very dry way, it doesn't get memorized. So it's like he makes a little story for each section of what he is explaining & think that's why his method works so well :)

@enelijit 13 лет назад

great videos,i wish u put numbers on your videos it might make it easier to know which one is next

@kevigard 14 лет назад
