An example would be the coagulation cascade of secondary hemostasis which leads to fibrin formation, and thus, the initiation of blood coagulation. Another example, sonic hedgehog signaling pathway , is one of the key regulators of embryonic development and is present in all bilaterians . [ 2 ]
A cascade effect is an inevitable and sometimes unforeseen chain of events due to an act affecting a system. [1] If there is a possibility that the cascade effect will have a negative impact on the system, it is possible to analyze the effects with a consequence / impact analysis .
In 1978, Kessler found that 42 percent of cataloged debris was the result of 19 events, primarily explosions of spent rocket stages (especially US Delta rockets). [12] He discovered this by first identifying those launches that were described as having a large number of objects associated with a payload, then researching the literature to ...

An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem.
For example, it can be important for understanding the knock-on effects of removing top predators from food webs, as humans have done in many places through hunting and fishing. A top-down cascade is a trophic cascade where the top consumer/predator controls the primary consumer population. In turn, the primary producer population thrives.
A representative example of a pericyclic cascade is the endiandric acid cascade reported by Nicolaou et al. in 1982 (Scheme 8). [ 4 ] [ 19 ] Herein the highly unsaturated system 39 was first hydrogenated to the conjugated tetraene species 40 , which upon heating underwent an 8π-conrotatory electrocyclic ring closure, yielding cyclic ...
The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke , injury, or cardiac arrest due to heart attack .
