Favism, that is G6PD deficiency, and drugs for Covid-19

Favism, that is G6PD deficiency, and drugs for Covid-19

A document, vital for people having Glucose-6-phosphate dehydrogenase deficiency (favism) is available. The link is https://www.epicentro.iss.it/coronavirus/pdf/en-report-covid-19-14-2020.pdf . In this document it is told that "Chloroquine and hydroxychloroquine currently applied to COVID-19 patients should be avoided in those with severe G6PD deficiency as they could trigger a hemolytic crisis in the patient". Other very important references are also given. Besides Chloroquine and Hydroxychloroquine, Primaquine and 8-Aminoquinolines are considered.

On the observation of Hypokalemia in Covid-19

On the observation of Hypokalemia in Covid-19: Hypokalemia is a low level of potassium in the blood serum. Here a survey of literature about the observation of Hypokalemia in Covid-19. In particular we consider the study published in a MedRvix preprint 'Hypokalemia and clinical implications in patients with coronavirus disease 2019 (COVID-19)'.

Vitamin D for Covid-19?

Vitamin D for Covid-19?


A small survey of literature about Vitamin D and inhibition and expression of interleukins and tumor necrosis factors. Could Vitamin D have a possible role in Covid-19 Cytokine Release Syndrome? A study of its role when tocilizumab is used exists, and therefore Vitamin D could be considered when tocilizumab is involved in the mitigation of the cytokine storm. However, another question also exists and it is the following. Might Vitamin D induce antimicrobial peptides to reduce SARS-CoV-2 replication?

Il Diritto di Contare (Hidden Figures)

Katherine Johnson Dies at 101; Mathematician Broke Barriers at NASA

She was one of a group of black women mathematicians at NASA and its predecessor who were celebrated in the 2016 movie “Hidden Figures.”

https://www.nytimes.com/2020/02/24/science/katherine-johnson-dead.html





"Ms Johnson helped our nation enlarge the frontiers of space even as she made huge strides that also opened doors for women and people of colour in the universal human quest to explore space," he said in a statement.

"Her dedication and skill as a mathematician helped put humans on the Moon and before that made it possible for our astronauts to take the first steps in space that we now follow on a journey to Mars."

Ms Johnson was awarded the Presidential Medal of Freedom in 2015. Then-US President Barack Obama later cited her in his State of the Union address as an example of the country's spirit of discovery.


This is the math that made Katherine Johnson — one of NASA’s “Hidden Figures” — a legend
Johnson, who died Monday at age 101, did groundbreaking work in helping return astronauts safely to Earth.

"The public needs more diverse role models in science. “When you think about what a scientist means, you probably think of an Einstein figure — a man in a lab or at a chalkboard with fuzzy, unkempt hair,” as my Vox colleague Julia Belluz has written. “When you think of a scientist’s voice, you might conjure Neil deGrasse Tyson or Carl Sagan. With these voices and images so pervasive in our culture, it’s easier to associate ‘scientist’ with ‘man’ — and in particular, ‘white man.’”

Women scientists like Vera Rubin, Nettie Stevens, Henrietta Leavitt, Rosalind Franklin, Johnson and so many others ought to be just as famous. Today, too many women — and minorities — still feel unwelcome in many corners of science. Johnson’s legacy shows them they have every right to be there."

ΟΜΟΝΟΙΑ ΣΕΒΑΣΤΗ

"Un'altra moneta, dell'età di Domiziano, reca la leggenda ΟΜΟΝΟΙΑ ΣΕΒΑΣΤΗ e una testa femminile velata e diademata, con sul davanti un papavero fra due spighe. Nelle serie numismatiche di età romana O. è raffigurata con peplo stretto sotto il seno, mantello al di sopra, le cui pieghe la dea regge con la mano, mentre sostiene una cornucopia semplice o doppia, ricolma di frutti, ovvero una patera; più raramente tiene un ramo di palma. È rappresentata quasi sempre eretta, assai più raramente seduta su un trono ad alta spalliera, o accanto ad un altare fiammeggiante, inghirlandato."


Con la stessa mente, in concordia

"La grandezza di molte parole sta nella loro semplicità - e la parola 'concordia' non è solo semplice, è quasi naïf." https://unaparolaalgiorno.it/significato/concordia

Un grazie di cuore a Giorgio Kaniadakis per la discussione sull'omonoia.
