Search and replace to remove italics in numbers preceding book titles

Hi,

Newbie here!

I have a long list of book titles in bold italics (see below). The formatting is always the same:

Number + period + space + Book title + space + text + paragraph break + text. 

Each entry is formatted using the same Paragraph Style, so they're fairly easy to pinpoint in the Search Box. 

Each entry is in bold italics, but I need to remove the italics from the numbers and the period preceding the Book Title.

A few examples:

1. Title [paragragh break]

Text
2. Title 2 [paragragh break]

Text
35. Title 35, December 1925 [paragragh break]

Text
428. Title 2.1 [paragragh break]

Text
1025. Title 22.2, January 1945 [paragragh break]

Text
1225. Title 10.49 (issue 490), December 7, 1973 [paragragh break]

Text
1333. Title 144, December 13, 1973 [paragragh break]

Text

And I would need this (no italics for the number and period at the beginning of the entry)

1333. Title 144, December 13, 1973 [paragragh break]

Text

Is there any search & replace function that would allow me to remove the number and period italics in each entry?

Thanks!
