nested-sets

I am using nested sets to represent a tree in mysql, like so:

Tree
ID
title
lft
rgt

Given the ID of a node in the tree, what is the easiest / best way to UPDATE that node as well as all of it's ancestors?

For example, let's say that the node ID (36) is 4 levels deep in the tree. I would like to update its title, as well as every parent node's title, all the way to the root, to the word "fish". (Should be four updates in all.)

Thanks for your help!
