We were interested in developing vaccination strategies against highly pathogenic human #coronaviruses with epidemic potential. Our previous studies, and those of others, defined the #RBD as a major target of neutralizing antibodies.

Gerade wieder viel Interesse an #Schnelltesten & neuen #SARSCoV2 #COVID19 Varianten: Zeigt, wie wichtig kontinuierliche Validierung von Diagnostika weiterhin bleibt. Unser Zentrum @gcevd @Hopitaux_unige führt seit 2020 kontinuierlich dazu Studien durch zusammen mit @FINDdx & @WHO
Diagnostik ist ein vernachlässigter Aspekt in der Kontrolle neuartiger Krankheiten, Studien dazu haben nur geringe Chance hoch publiziert zu werden, Drittmittel dafür gering, Expertise, die man für gute Diagnostik braucht, wird unterschätzt & fehlt oft massiv in Expertenpanels
Dabei ist Diagnostik DER Schlüssel, Fälle einer neuen Infektionskrankheit sofort zuverlässig zu erkennen. Wie fragil die diagnostische Kapazität schnell wird, hat sich Anfang 2020 gezeigt, asl plötzlich extrem viele Proben getestet werden mussten, aber es an allem fehlte.

Rutte and Dutch parliament continue to cover up their crimes against humanity with scandal. They cower behind incompetence to mask malice and absolve themselves from responsibility, shifting blame to the people. We need to put to words the montrosity happening in real time 🧵
The hospitals and intensive care capacity has already been reached; they are by definition at #codezwart and will soon be rationing care, if not already behind closed doors. 🧵2
Dutch Parliament is now steering towards excess mortality; thanks to delayed and inconsistent reporting, they can hide actual deaths due to #covid19. An extra 3,000 deaths from this wave alone, half of which could have been prevented with timely booster shots, is acceptable. 🧵3

The @SwissScience_TF proposes to halve confirmed #SARSCoV2 cases every two weeks to reach less than 500 cases in January. What does this mean regarding the reproduction number? A thread about doubling times and half-lifes of #SARSCoV. (1/n)
The figure (in German) shows the relationship between the reproduction number and the time in which the number of new #SARSCoV infections double (red) and reduce by 50% (green). (2/n)
In early March 2020, the virus spread uncontrolled in Switzerland with a reproduction number of 2.8 which corresponds to a doubling time of 3 days. (3/n)
A short thread on PCR #SARSCoV2 There’s been a lot of discussion recently about the use of PCR (Polymerase Chain Reaction) for the diagnosis of #SARSCoV2 infection, and the interpretation of its results. 1/n
Hopefully, this thread can provide some background and context for those who are not familiar with the technique. PCR has become the cornerstone of molecular diagnostics in virology, and is, simply put, a technique for amplifying DNA (and indirectly RNA). 2/n
It can be used for straightforward detection purposes i.e. to provide a qualitative yes/no answer. Alternatively, it can be used to provide a quantitative result, i.e. to tell us how much of something is present. 3/n

PROBLEMÁTICA ACTUAL ❗❗🗣️ Yo, @EchinusMelo soy becaria posdoctoral en el extranjero por @Conacyt_MX . Nuestro compromiso es cumplir con actividades en programas de posgrado nacionales. Para que se libere nuestra beca debemos probar que regresamos al país y que trabajamos 6 meses
Cómo lo comprobamos? 1) Nos piden copia de TODO el pasaporte o un registro de entradas y salidas por migración. Y debemos probar ingresos recibidos por 6 meses, sin importar si lo expide @Uber o @LaCasaDeTonoMx (100% fans).
Debido a la pandemia/cuarentena, pedimos a @Conacyt_MX que nos diera la liberación de beca al terminar nuestra estancia y que no nos pudiera estos comprobantes que, a nuestro parecer, son inútiles si quieren evitar la famosa #FugaDeCerebros
