Please see How do I compose an effective node title?. A good title lets monks know immediately whether they'll be able to help you. A title such as yours is likely to dissuade monks from helping you.

And now some issues:

1. You need to quotemeta since your match string contains regular expression Metacharacters ('(' and ')'). You could also manually escape the characters, but you are more likely to run into trouble with that.

2. You shouldn't use g on a regular expression (or any Modifiers) unless you need it. In this case, it is a bug but not the bug you were hitting.

3. And in any case, your string does not contain the term you are searching for. The closest occurrence is <Tr><Tc>At transplantation (POD ), without the '0'.

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
