Moreover, ALS pathogenesis also progresses without axonal neurofilaments [ 57], and over-expression of NEFH prolongs survival of SOD1-transgenic FALS mice, prompting the hypothesis that NFs primarily act as an abundant buffer for otherwise deleterious processes, such as actions of SOD1 gain-of-function mutants [ 58] or aberrant tyrosine nitrosylation or phosphorylation [ 1, 59, 60].
It is believed that an "eclipse" period where reinitiation is not possible allows a buffer time for the other processes such as RIDA to take effect and thus for the levels of DnaA-ATP to decrease below the critical level for initiation.
Factors affecting on-chip electrophoresis processes, such as running buffer, separating voltage, injection modes and sampling time, were investigated and optimized.
However, when oxidants or other environmental stress alter this ratio, the shift in the GSH/GSSG redox buffer may influence a variety of cellular signaling processes, such as activation of transcription factors and cellular activation (45).
Finally, even well-prepared buffers are susceptible to CO2 uptake and other undesirable processes such as microbial activity.
These results support the idea that some cytoskeletal regulators are important to buffer environmental variations and ensure the proper execution of basic cellular processes, such as the control of cell shape, under environmental variations.
On the other hand, the data stored in the long buffer are frozen during the WFC data processing and the subsequent measured data are sent to the short buffer, as it is necessary to apply a time-consuming (non-real-time) processes, such as data compression or digital filtering to the WFC data.
This proposal is fully consistent with the assumptions of PUCC in which parietal cortex is a temporary buffer of activated information, and DPC is specifically involved in goal-directed/executively demanding task processes, such as working memory.
Therefore, the intracellular Ca2+ transient decline primarily depends on NCX and slow processes such as mitochondrial Ca2+ uptake and sarcolemmal (SL) Ca2+ATPase (27), in the presence of extracellular Na+ and Ca2+ (control buffer with 10 mM caffeine).
Evolution involves both deterministic processes, such as selection, and random processes such as drift.
