Each of the two recorders has a beacon, attached to the outside of the black box, which once activated by contact with water makes a sound every second.
Mature B and T cells exit the primary lymphoid organs and are transported via the bloodstream to the secondary lymphoid organs, where they become activated by contact with foreign materials, or antigens.
Conclusion: These results show that aprotinin, but not tranexamic acid, modulates the inflammatory response by reducing the IL-8 secretion of blood cells activated by contact with foreign surfaces.
Mature B and T lymphocytes exit the primary lymphoid organs and are transported via the bloodstream to the secondary lymphoid organs, where they become activated by contact with foreign materials, such as particulate matter and infectious agents, called antigens in this context.
It looked somewhat more sleek than the others, and is activated by contact with skin.
Microarray analysis showed that 437 out of 54,675 probe sets were enhanced in monocytes activated by contact with stimulated T cells, 164 probe sets (i.e., 38%) being inhibited by HDL.
In T cells, the p38 MAPK is activated by contact with APCs or by different cytokines.
In the hypoinflammatory phase of sepsis, macrophages are alternatively activated by contact with apoptotic cells or their secretion products.
Neutrophils are activated by contact with cryptococcal components, for example the dose dependent release of pro-inflammatory cytokines in response to cryptococcal capsule (Retini et al., 1996).
When the receptor proteins are activated by contact with a microbe, they interact with a family of proteins called SFKs, which in turn stimulate communication systems called signaling pathways inside the macrophages that activate their immune responses.
Our results also indicate that it is unlikely that blood platelets are directly activated by contact with artificial surfaces of PM because we observed no association between platelet aggregation and PM concentrations for time lags representing direct effects.
