Weightlessness kills cancer cells?

[GuyGadebois]

You think cancer cells, they do not care damn the feeling of weightlessness provided by a saltwater bath!

You think that cancer cells, they make the difference between artificial weightlessness and "natural" weightlessness and that they can "not give a damn" when they are fooled by a centrifuge whose operation you have not even understood. ?

I do not believe in your weightlessness and, indeed, I would like to understand how a centrifuge can reduce gravity ...

I suppose it is by forcing the precession, as when one forces the inclination of a spinning bicycle wheel. Microgravity can only be obtained close to the ground in a plane in free fall.
The problem is that it doesn't just work on cancer cells

In microgravity experiments, an almost total inhibition of the proliferation of human lymphocytes, however stimulated by a substance capable of promoting their division, has been observed, and it has been concluded that it is on the intracellular scale that the action must be carried out. severity: there was inhibition of a substance (a phorbol ester, in this case), the role of which is to activate protein kinase C, an intracellular enzyme.

Under the same conditions, inhibition affects two proto-oncogenes (c-fos and cjun) (cell differentiation genes involved in the genesis of cancers), even after stimulation of the cells.

On the other hand, during (moderate) centrifugation experiments, the expression of the proto-oncogene c-myc was increased.

In summary, and however few experiments may be, they reveal that, when it comes to human cells - and, what is even more interesting, human genes - microgravity rather has an inhibitory effect, hypergravity. a stimulating effect. If we relate these observations to the curvature of space-time, there could be a correlation between the fundamental states of the atom and the weakness of genetic expression, and on the other hand between the excited states of l atom and high intensity of gene expression (26). http://www.astroariana.com/La-gravitation.html

It can but only on 1/2 turn (to roughly simplify) ... and suddenly on the other 1/2 turn the cells take 2g.

[Christophe]

But if we imagine a continuous supply of the centrifuge ... well the material flow can remain at almost 0g ...

We will be able to send hospitals into orbit, it's great
Good health insurance premiums may increase, given the cost of transportation ...

Unless we treat the sick in centrifuges

You don't believe in physical laws, so ... it doesn't give a damn.

lol ... actually the centrifuges are used to train the astronauts, but it's to prepare them for accelerating takeoff.

Centrifuges can also create artificial gravity in weightlessness https://couleur-science.eu/?d=16bab7--c ... tificielle.

[dede2002]

Of course, but here we are talking about the opposite ... An artificial gravity in gravity!
