Activation

Activation

(Science: radiobiology) activation occurs when a particle interacts with an atomic nucleus, shifting the nucleus into an unstable state, and causing it to become radioactive.

in fusion research, where deuterium-tritium is a common fuel mixture, the neutron released when (D _ T) combine to form (4He _ n) can activate the reactor structure. In this case the 4He is inert, the neutron sticks to another nucleus, and the neutron _ nucleus reaction creates an actvation product. Sometimes called radioactivation.

See: activation product, activation analysis.

Re: connexins & pannexins

... channels formed of the deuterostome homologues of innexins (pannexins) differ from connexin channels in terms of important structural features and activation properties. These differences indicate that the two families of gap junction proteins serve distinct, complementary functions in deuterostomes. ...

age and cumulative impact of carcinogens

... never leave your system, so their damages accumulate more if they enter while you're young. Perhaps cancerous cells are more prone to oncogene activation because their cell division cycles have been messed up, or just because they divide more often, so an oncogene activated at a young age has ...

EC50 depending on cell number?

... from the principle. Say I have compound X that I use in a 96-well format and in each well I have 1000 cells. I find out that I I have a receptor activation EC50 at 1 uM in a medium voume of 50 ul. If I now repeat the same test with 5000 cells per well, do I now get the same activation only when ...
