Some airlines have experimented with reducing business fares but most have not cut their walk-up fares, arguing that price reductions do not stimulate an increase in business travel.
These immature chondrocytes are metabolically highly active and capable of spontaneous matrix formation, but do not stimulate an immune response.
Moreover, they are relatively easily transfected into cells and do not stimulate an innate immune response in the host cell.
This is important for tumor immunity because a variety of tumors are potentially immunogenic but do not stimulate an effective anti-tumor immune response in vivo.
Some activities (for example, a progressive jogging program) charge and stimulate adaptation of the cardiovascular system, but do not stimulate an adaptive bone response that would increase bone density [ 51].
First, in mice sperm, a cAMP increase alone upon stimulation with HCO3- does not stimulate a Ca2+ influx (e.g. Wennemuth et al., 2000, Journal of Biological Chemistry; Wennemuth et al., 2003, Development; Carlson et al., 2007, Developmental Biology).
Biological tests revealed that repeating unit 3, lacking the lipid moiety, did not stimulate a pro-inflammatory response in human monocytes (hMNCs).
Removal of pastoralism does not stimulate a return to a pristine state nor does it maintain the existing second state but, instead, creates an entirely new third state where the artifacts of engineering persist, but the engineering agent is removed.
Unlike ketamine and nitrous oxide, xenon does not stimulate a dopamine efflux from the nucleus accumbens.
