Reply to comment by Bryan_Waters in Autopsy-based histopathological characterization of myocarditis after anti-SARS-CoV-2-vaccination by Razariousnefarian

I've seen standard histology fixation solution referred to as 4% because it's ~4% w/v of formaldehyde. The 10% is v/v.

I wish I was more smarter like you guys :/

Not necessarily smarter, just better educated in their fields.

I'm going to hire an electrician to replace my breaker panel. Is he smarter than me? In his field of expertise, 100% he is. Could I learn it if I dedicated 5 years or so? Absolutely.

Just don't ask me to learn and understand quantum mechanics. That's probably outside of my realm.

This is very true. Thank you. I appreciate that.

Anyone who says they understand quantum mechanics doesn't.

I don't understand quantum mechanics

I tend to trust people more when they say "I get the gist of it".

Yeah, I understand some concepts about "this is the way things are."in rough, layman's terms, but not the how's and whys.

Just not true. What is true is that quantum mechanics has limits.

I read all of these comments and I’m fairly certain that most of what I read was definitely words. That’s about as far as I got.

Dont trip, it's just jargon. Look up words you don't understand. Repeat forever.

Wow thanks man! You’re a nice person.

It just means we've had the misfortune to be in a lab reeking of formalin. You're not missing out on anything meaningful or fun. :-)

And as other folks have said, it's just jargon. The first person said the heart tissue may not have been preserved in a standard way and that could impact the results. I'm pointing out that there are some less-common ways to describe the chemical used to preserve the tissue. We don't know which is right, whether they did something unusual or used very unusual language.

You guys are all so nice! Thank you! Honestly you guys have made my day.

This is why it’s standard practice to have scientists very similar to your work be the ones reviewing your papers for submission. It’s minutiae you wouldn’t know unless you also do the same type of protocol. You’ll notice it in grad school journal clubs. The best critique are people doing similar things while others who are equally talented can only ask bigger picture questions

I dated a woman for a while that had a p.h.d. She used it working for a college to translate papers written by faculty into language they could use to teach to students.

The hardest thing to teach is the desire to learn. Everything else just takes time and patience.

I was going to say the same until I read the comment below. Thanks.

That’s interesting, is this outside of the US? I’ve never seen it indicated this way in a Pathology report or in a lab SOP, in or out of the US.

It is German, not sure if that changes anything.

I've seen it in papers from people fixing tissue culture cells or animal tissues. Also I don't think fixation in 4% v/v would even crosslink well enough to section and stain. Their photomicrographs looked pretty typical for FFPE.
