My two posts above should be read with my 2nd July post #74560490.

For people like me (with less than the best IT skills), please do an advanced search for keyword MSB, type in my handle as the author and press the search button by scrolling down a bit (if you are doing things on the phone like me). Then you need to tab my handle in order to bring up the full list of my posts (the first search result is a shortlist). There’s only one post I did under the “Cell therapy” thread on 2 July. That would be post #74560490. I discovered an answer to a question that @otherperspective had asked as I tried to find an answer to a different question of mine. (That’s the long-winded background to my 2 posts above.)
