@vikramml @RealVladivostok Stephen Chen is a sensationalist.

60°C for one hour is usually enough for roughly a 5-log reduction in PFU terms in CoVs (see my post above).

Hence, starting with >100,000 viral particles could still allow infecting cells afterward.
@vikramml @RealVladivostok Gross appearance need not be altered during thermal inactivation, which involves thermal denaturation of key proteins.

90°C for 10 minutes reliably inactivates CoVs, including SARS-CoV-2.
@vikramml @RealVladivostok I am unsure why the article even bothered mentioning that the Spike protein wiggles. All proteins wiggle.

Spike count varies. The D614G mutation increased it by roughly a factor of 5, increasing infectivity. It is now carried by the majority of SARS-CoV-2 samples.
@vikramml @RealVladivostok The Kellermayer paper on atomic force microscopy of individual SARS-CoV-2 virions is here:
biorxiv.org/content/10.110…

It is true that SARS-CoV-2 is particularly compressible and elastic. Influenza viruses are somewhat similar, but stiffer (more internal reinforcement). ImageImageImageImage
@vikramml @RealVladivostok It isn't clear what practical significance this may have, if any, and it isn't apparent whether this is any different from any other coronavirus. I doubt it.

Again, the most useful points for a broad audience:

- get vaccine ASAP; prefer mRNA or Novavax; 2 doses far better than 1

- store RCT-validated early treatments: bromhexine-or-ambroxol + nitazoxanide-or-niclosamide, fluvoxamine, ivermectin

- N100 masks

For a medical audience:

- decide what the word "evidence" means:
a) "clinical results with appropriate sample(s) and endpoints"
b) "what huge lumbering institutions claim ex cathedra with no citations"
c) "what gilead et al. claim"
d) "peer best practices"

- take low-risk bets
If in doubt, *ask the patient*.

People have a fundamental right to participate in their own health-- *they already do so 99% of the time anyway*.

'This might help with X; it's a bit less certain; may cause Y side effects; studies say usually well-tolerated; do you want to try?'

The continued failure to trial or use ITPP in critical care is an indictment against the regulatory and productive institutions of our supposedly-advanced (increasingly just shorthand for 'gridlocked') economy.

en.wikipedia.org/wiki/Myo-inosi…

It makes blood transport oxygen better.
It costs practically nothing.

Thousands of people already use it for athletic activities.

It has no side effects, is safe at huge doses in animal studies, and has never had a serious adverse event reported in the community ('that's informal' it's post-marketing surveillance..).
The fact that we are jamming tubes down people's throats before giving this, or for that matter even giving cyproheptadine, absolutely disgusts and appalls me.

>Oh that isn't proven

Yes. It. Is.

READ A BOOK; THEY ARE BOTH LITERALLY BASIC PHYSIOLOGY.

Efficacy is nowhere near Novavax or the mRNA options (Pfizer/Moderna).

Much like Sinovac/Sinopharm(/CanSino), the tell for this is the headline numbers focusing solely on severe COVID-19 and ignoring mild/moderate cases.
Even for moderate, only 66% effective....

>One hope is that the efficacy of the Johnson & Johnson vaccine could rise if it is given as a two-dose regimen.

Obviously, yes! This is much more promising.
Single-dose frankly seems gimmicky, in a very specific sense:

This is effectively just offloading the debate about whether to halfway-dose existing vaccines to a new vaccine candidate instead-- one that has actually been trialed in this dosing schedule.

A couple things about which I would like to be clear, from the now-big account (likely smaller over time):

1) do not ever @/DM to ask where I am or act like I owe you something-- pay me a bitcoin if you want that kind of attention, I know that is pocket change to some of you
2) I have a life outside of COVID-19 and a very, very detailed post history that is approximately two clicks away, depending on your choice of platform access method: search feature, "__ice9 <whatever topic>" papers generally do not become 'out of date' and a result is a result
3) I am frankly a bit bored. The acute disease was obviated months ago by dual entry inhibition. Not my problem if the west ignored it because it came from Iran, or due to statistical illiteracy or vile conflicts of interest (hi Gilead puppets 🎭). Fluvoxamine looks great too.

Reminder:

If you test positive for COVID-19 and do not have fluvoxamine on hand, please consider enrolling in this clinical trial.

It's simple, remote, and important. It's a 50% chance to get fluvoxamine.

You can keep using other medications. Delivery is overnight shipping.
You can read the protocol summary here for more details on the trial if desired:

clinicaltrials.gov/ct2/show/NCT04…

My prior post about it is here:

Fluvoxamine was 100% successful in preventing hospitalization in an earlier RCT for use in mild COVID-19 within a few days of onset.

It was also associated with a 100% lower risk of progression to hospitalization in observational study.

Among the best.

NAC apparently has antiviral effects vs. SARS-CoV-2.

chemrxiv.org/articles/prepr…

EC50 ~10μM
163g/mol * 10μM = 1.6mg/L
Plasma, as VoD=0.4L/kg

Hittable at 600mg oral q.i.d.:

pubmed.ncbi.nlm.nih.gov/2029805/

link.springer.com/article/10.100…

Unlike for vWF, Spike inhibition by NAC does not need IV.
Note I really do mean 600mg *q.i.d.* (4x/day) if tolerated; short half life. Safe in other studies.

link.springer.com/article/10.100…

Side note: strangely demanding PK study; very rigorous protocol. Hope participants were at least paid well. But they got us a number so I am pleased.
NAC may not have a large impact in monotherapy, given only EC50 is hittable (not EC90 except perhaps IV) and gappiness in plasma concentration peaks even q.i.d. (slightly compensated by permanent nature of damage done to exposed Spike copies).

But it looks like a good addition.
