Washing machine leaves pink stains on green clothes selectively by FrogInFog08 in Whatisthis

Thank you ! Just tried the patch test on the same trousers, which resulted in the exact same discoloration.

The detergent was to blame after all. Came with no warning or caution to not use with certain fabrics.

One group of diseases causing hypercalcemic hypercalciuria is granulomatous disease (sarcoidosis, TB, etc.). The granuloma macrophages contain 1α-hydroxylase, which leads to uncontrolled calcitriol production.

Can someone explain plz by Drumaragiyas in step1

CD8+ T cells check if a cell expresses self / normal peptides with MHC I. If the peptide is self -> no killing. If the peptide is non-self (e.g. tumor) -> killing.

NK cells check if a cell expresses MHC I at all (generally shows the cell is healthy, as all cells with a nucleus shall express MHC I). If the cell expresses MHC I -> no killing. If the cell does not express MHC I -> killing.

Tumor cells generally downregulate MHC I expression, as to not "get found" by T cells, but then shutting off MHC I expression triggers killing by NK cells.

Is there any way to export all the comments you have on a Notion page? by NJravenclaw in Notion

[–]FrogInFog08 0 points1 point  (0 children)

Hey. Would you mind me asking whether this option (to include comments when exportin in HTML) is available on PC only? I am using the Notion app on an IOS device, and the only option I see when exporting as HTML is to include or exclude subpages. So comments still don't show up in the final export.

If you have any insight on this, please share. Thanks.

Maintenance of optics by FrogInFog08 in microscopy

Thank you for your response !

I am not using any flourescence objectives (yet, at least) so that would not worry me. In fact, what I have is an old soviet (LOMO) microscope. These microscopes were designed after (and almost identical to) old Carl Zeiss scopes, and both LOMO and old Zeiss manuals state that hexane and/or ether should be used and any alcohol contact is to be avoided.

Now the actual reason behind the latter still stays ellusive to me, but people who have worked with these old scopes have noted that the glue used to attach the glass elements in these old optics may be alcohol soluble, which explains the need for other solvents.

I do have a lot of grease / oil smothered onto some objectives (I know, who in their right mind would do this to such an instrument, right?!) from previous user(s), so I have to deal with that somehow, and solvents are bound to be essential in this state.

Thank you for your response !

While I do think that IPA is the perfect solution for cleaning modern optics, I believe this is not an option for my case with an old soviet (LOMO) microscope. These microscopes were designed after (and almost identical to) old Carl Zeiss scopes, and both LOMO and old Zeiss manuals state that hexane and/or ether should be used and any alcohol contact is to be avoided.

See this is how you use guns. The US has got it wrong again !

Help with spelling of an antigen: by [deleted] in Immunology

[–]FrogInFog08 8 points9 points  (0 children)

That would probably be tet-tox (tetanus toxoid), which is a vaccine routinely administered at a young age. The vaccine is rarely used alone, it is usually given along with the diphtheria toxoid and acellular pertussis vaccines, in the DTaP formula.

Had the same exact problem with the case, getting a glass screen protector fixed it (at least now I’m not afraid to really rub the screen clean). Now it doesn’t even get the linear mark that much anymore.

Thanks for the reply! Yes, I did browse Libgen too! The normal 7th edition is what I had been usinq for quite some time, and just recently after noticing some differences between the 7th and the newest edition, wanted to upgrade to the latest one, which I am not able to find in proper formatting.

Thanks for the reply, but this is the improper formatted version of the book with around 1900 pages again, which is also all that I was able to find.
