The breakout of T-cell immigration accompanying SAH is a critical and complicated pathway underlying the development and maintenance of delayed neurologic deficits.
Unlike the mechanism of noise-induced hair cell loss, the mechanism of styrene-induced hair cell loss must involve a much more complicated pathway; that is, the styrene probably affects not only OHCs but also other parts of the animal.
The problem of low yield results from a complicated metabolic pathway and a rate-limited enzyme.
As a result, ciliary photoreceptors are dependent on a supply of a particular form of vitamin A (11-cis retinaldehyde), which has to be synthesized by a complicated biochemical pathway (see Lamb and Pugh 2004).
This indicates a complicated treatment pathway, particularly for patients who had resection earlier than 25 days, and requires further investigation.
Once this complex is formed, the TGFβ receptors activate a complicated signaling pathway that controls how cells grow and divide.
However, the Group I self-splicing intron is a much more complicated ribozyme than either the hammerhead or the L1 ligase; for example, the tertiary structure of the Group I intron is established by a complicated folding pathway.
As such, NF-κB represents a complicated survival pathway that may be both activated and repressed by PDT, depending on the severity of the oxidative insult and the interaction with additional signaling pathways.
Nonsense even the complicated pathway of blood clotting (an example much favored by creationists) is the subject of coherent, evidenced-based explanations.
