First, implicit in West's model is that spontaneity relates to peaks in fluctuating levels of longer-term concern; that is, that 'spontaneous' quit attempts are typically preceded by periods of deliberation that are not strong enough to trigger action, rather than occurring completely out of the blue.
Diathesis-stress interactions are expected to result in fluctuating levels of symptoms as individuals with various degrees of vulnerability encounter various levels of stress in their lives.
There is a degree of reciprocity in the fluctuating levels of Egr1 and Egr2 proteins, in that Egr1 is near undetectable by day 2 of differentiation, concomitant with maximum expression of Egr2, while Egr1 reappears on day 3 as Egr2 decreases (Fig. 1).
Instead, as an embryo develops, sex-related genes are turned on and off in response to fluctuating levels of hormones in the womb, produced by both mother and child.
With progression to PDD these deficits worsen, and impaired vigilance also develops with fluctuating levels of alertness (Ballard et al., 2002), which in turn drives fluctuating levels of cognition (Walker, 2000).
The path analysis model specified the flow of unidirectional impact from change in the prison population to changes in the substance abuse and mental health treatment populations in the community in the larger contexts of fluctuating levels of violent crime and illicit drug use (see Figure 2).
Acute withdrawal in long-term alcohol abusers can result in tremor, hallucinations, seizures, agitation, and fluctuating levels of alertness [ 14].
The occurrence of breakthrough bleeding was considered to result from incomplete suppression of ovarian activity resulting in fluctuating estrogen levels, which can occur even when ovulation is inhibited.
Spalax (blind subterranean mole rat), is a mammal adapted to live in fluctuating oxygen levels, and can survive severe hypoxia and hypercapnia.
Maximum serum levels are reached 2 6 hours after ingestion, and result in fluctuating serum T levels (for a review see Behre et al 2004).
In addition to being painful and inconvenient, injections also bypass the liver, delivering insulin directly to muscle cells, which results in fluctuating blood insulin levels.
