Although both integrins are known receptors for laminin-332, their signaling pathways, signal duration, and dependency on laminin-332 are different.
PFOA-related questions pertained to a) sources, pathways, and duration of exposure(s); b) possibility of follow-up studies that would include family members; c) likelihood of bioaccumulation; d) factors likely associated with higher concentrations, such as length of residence; e) recommendations for preventing future exposures; and f) implications for the puberty study.
All other types of mercury exposure (e.g., other forms of mercury, exposure pathways, or durations of exposure or dosages), other concomitant exposures (e.g., other chemicals, other hazards such as noise or accidents), or comorbidities (e.g., acute intoxications, cancer, silicosis, cardiovascular or infectious diseases) were not considered for the current definition of CMMVI.
Mutations in the deoxyribose nucleotide salvage pathway can affect duration of the lag as well as the rate of killing.
This framework can be extended to predict very important features of the RNAi pathway including the duration of gene silencing for the different siRNA molecules.
It is probable that adjustment for the total energy intake may be over-adjusting, because it may be part of the causal pathway between sleep duration and poor glycemic control.
Because of these capacity-depleting effects even at the initial steps of the second pathway, the exposure duration might be more important than in the first pathway where a more threshold-like mechanism indicates the switch from sensory to non-sensory responses/reflexes.
Ten of the studies that met the inclusion criteria addressed milk production, but heterogeneity in exposure pathways, patterns, and duration precluded meta-analysis or data pooling.
This method uses a background photopic light to saturate the rods, effectively isolating cone photoreceptor pathways; and long duration flashes are used to separate responses from downstream ON- and OFF- bipolar cells with ON-bipolar being favored at flash onset and OFF-bipolar cells at offset.
This variability in affected cellular functions suggests various toxicity pathways, depending on duration of exposure, MeHg concentration, cell type and individual susceptibility.
