The excessive extracellular DA concentrations induced by repeated drug exposure engage compensatory mechanisms that function to constrain tonic DA neurotransmission.
In sensitized subjects, allergen exposure engages resident nasal dendritic cells.
However, the effects of exposure and engaged activity may be different from one another.
[2] To estimate the amount of vitamin D3 a person makes from outdoor UV exposures when engaged in different activities, we first determined how much vitamin D3 a person would make from an erythemally weighted UV dose with uniform geometry, such as the UV dose from a tanning bed.
The latter may instead require repeated exposure to engage hippocampal replay-dependent mechanisms for memory consolidation.
Children need to be given exposure to and engaged in computer sciences at an early age.
We conducted a study to assess respiratory symptoms, pulmonary function, and tea dust exposure of workers engaged in early-stage tea manufacturing and to identify contributing factors of respiratory effects.
A further strength of the study is the likely higher exposure of workers engaged in PQ production than many of the subjects in case control studies classified as exposed to PQ.
However, BiP, deleted of its helical lid (BiPlidless), still formed linker-dependent oligomers that dissociated upon exposure to ATP, engaged peptides in a hierarchy similar to that of wildtype BiP oligomers (compare Figure 2F with Figure 3 figure supplement 1C) and protected the interdomain linker of LY-BiPV461F tracer similarly to wildtype BiP.
For example, Heyne and Rollings (2002) recommended giving adolescents with anxiety-based school refusal more input into the decision-making about the type of exposure to be engaged in (i.e., graded school return vis-à-vis immediate full-time return).
Further, children can experience greater environmental exposures by engaging in hand-to-mouth behaviors that increase their risk of ingesting pesticides found in the home (McCauley et al. 2006b; Quandt et al. 2004).
