So now we have a certified Serologic testing of Red Cross US blood donations to identify SARS-CoV-2-reactive antibodies, and that battery of testing shows widespread presence of SARS-CoV-2-reactive antibodies in donations made between December 2019-January 2020

Charting early steps for H₂ infrastructure in Europe.
👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em
The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

Why can cefepime cause neurological toxicity?
And why is renal failure the main risk factor for this complication?
The answer requires us to learn about cefepime's structure and why it unexpectedly binds to a certain CNS receptor.

Let's establish a few facts about cefepime:
🔺4th generation cephalosporin antibiotic
🔺Excretion = exclusively in the urine (mostly as unchanged drug)
🔺Readily crosses the blood-brain barrier (so it easily accesses the brain)
https://t.co/rjYG1BfGPR
3/
The first report of cefepime neurotoxicity was in 1999.
A patient w/ renal failure received high doses of cefepime and then developed encephalopathy, tremors, myoclonic jerks, and tonic-clonic seizures.
✅All symptoms resolved after hemodialysis.
https://t.co/u7JLVitQpp

Cefepime neurotoxicity is surprisingly common, occurring in up to 15% of treated critically ill patients (w/ symptoms varying from encephalopathy to seizures).
💡The main risk factors = renal failure and lack of dose adjustment for renal function.
https://t.co/nxbnzSq8AR

What about cefepime induces neurotoxicity?
One clue is that it's not the only antibiotic that causes neurotoxicity, particularly seizures.
This actually is a class effect w/ other beta-lactam antibiotics (including penicillins and carbapenems).

Working on a problem reduces the fear of it.
— James Clear (@JamesClear) August 30, 2020
It\u2019s hard to fear a problem when you are making progress on it\u2014even if progress is imperfect and slow.
Action relieves anxiety.
https://t.co/A7XCU5fC2m
We often avoid taking action because we think "I need to learn more," but the best way to learn is often by taking action.

Unfortunately the "This work includes the identification of viral sequences in bat samples, and has resulted in the isolation of three bat SARS-related coronaviruses that are now used as reagents to test therapeutics and vaccines." were BEFORE the
chimeric infectious clone grants were there.https://t.co/DAArwFkz6v is in 2017, Rs4231.
https://t.co/UgXygDjYbW is in 2016, RsSHC014 and RsWIV16.
https://t.co/krO69CsJ94 is in 2013, RsWIV1. notice that this is before the beginning of the project
starting in 2016. Also remember that they told about only 3 isolates/live viruses. RsSHC014 is a live infectious clone that is just as alive as those other "Isolates".
P.D. somehow is able to use funds that he have yet recieved yet, and send results and sequences from late 2019 back in time into 2015,2013 and 2016!
https://t.co/4wC7k1Lh54 Ref 3: Why ALL your pangolin samples were PCR negative? to avoid deep sequencing and accidentally reveal Paguma Larvata and Oryctolagus Cuniculus?
