La empresa española pharmamar trabaja con un compuesto antitumoral, el aplidin para tratar de saber si es capaz de frenar el coronavirus, covid 19. Ha sido capaz de demostrar está actividad frente al nuevo virus en trabajos in vitro gracias a los estudios conjuntos con el CSIC. También ha sido demostrada está actividad frente al covid 19 mediante la inteligencia artificial gracias a la universidad de Pittsburg.
Y va a comenzar un ensayo con enfermos de coronavirus en colaboración con varios hospitales españoles.

New path of origin for macrophages
Noticias de biología
It was thought that all macrophages were created from hematopoietic (blood) stem cells. However, some of these immune cells had also been found to exist in the yolk sac prior to the appearance of stem cells. For a long time, the existence of these extraembryonic macrophages was a puzzle to scientists. During a sabbatical at King's College in London, Dr. Christian Schulz, internist at the Deutsches Herzzentrum (German Heart Center) of the Technische Universität München, and his research colleagues set about investigating the development of macrophages in mice....

First description of a triple DNA helix in a vacuum
Noticias de biología
A team of researchers at the Institute for Research in Biomedicine (IRB Barcelona) and the Barcelona Supercomputing Center (BSC) have managed for the first time to extract trustworthy structural information from a triple helix DNA in gas phase.
One of the most relevant biomedical consequences of this study is that it could avail the development of the so-called antigen therapy. This therapeutic approach, which is based on DNA triple helix structures, would switch off the activity of the genes involved in a given disease.

Mutations behind flu spread revealed
Noticias de biología
At a Royal Society meeting in London about H5N1 research yesterday, the thus-far silent scientist spoke openly about his results after the National Science Advisory Board for Biosecurity (NSABB), an independent advisory group to the US government, unanimously voted last week that Kawaoka’s paper should be published in full. Nature intends to “proceed with publication as soon as possible”.
His experiments began when he tweaked the H5N1 virus to reproduce in a ferret’s airways. He introduced random alterations into its haemagglutinin (HA) protein, which it uses to stick to host cells. From the resulting library of mutants, he isolated viruses with two mutations in HA — N224K and Q226L — that could stick to receptors in human tracheal cells. That is something H5N1 viruses cannot usually do....

DNA donors rights

Genetics researchers are divided on the matter of incidental findings. Conventional research ethics holds that participants should not be told of their individual results, to keep them from expecting to benefit personally from the study. What's more, reporting such findings can be a logistical challenge because many studies strip identifying information from donated samples. But, increasingly, geneticists are embracing the idea that research participants have a right to know of any unwelcome surprises in their genome. “If we really believe this is medically valuable and useful data, then we have to act on it,”...
