The opposed findings of Portas and colleagues [22], who reported preserved activation of the auditory cortex and thalamic regions during light NREM sleep, may originate from the use of more salient, especially personal stimuli such as the own names.
First fMRI studies performed during NREM sleep applying acoustic stimulation showed contradictory results: Portas et al. [22] as well as Redcay et al. [23] and Wilke et al. [24] identified preserved activation of the primary auditory cortex in light NREM sleep in adults and children, respectively.
The result for bosentan is intriguing as many of the detrimental actions of ET-1, particularly in cancer, may use the β-arrestin pathway, and this suggests the potential to block a deleterious pathway while preserving activation of a beneficial pathway.
Our present study may offer a mechanistic explanation for the T cell preserving activity of low-dose prednisolone, i.e. by reducing general immune activation.
For example, selective inhibition of proinflammatory STAT1 activation while preserving ISGF3 activation and antiviral responses may represent a fruitful approach [ 78].
Having shown that PVRL4-driven cell-to-cell attachment could preserve SFK activation even in the absence of substratum attachment, we hypothesized that SFK activation is a critical driver of the observed ability of PVRL4-expressing cells to withstand the loss of anchorage.
Although the individual merits of resistance training versus vibration training cannot be quantified with such a study design, the efficacy of this combined countermeasure to preserve neural activation and maximal steady-state torque is reported elsewhere (Mulder et al. 2007).
Interestingly the choice between p53-induced senescence and quiescence, in a context of cell cycle blockade, would be mediated by the activity of the mTOR pathway and the strength of the p53 response: while p53 modest activation preserves mTOR activity and therefore results in senescence, strong p53 activation inhibits mTOR and result in quiescence [ 29- 31].
Miller, S. L. et al. Age-related memory impairment associated with loss of parietal deactivation but preserved hippocampal activation.
Pore structure analysis showed that the pristine mesopores were basically preserved during activation and the micropores were mainly generated within the mesopore wall.
Pore structure analysis showed that the pristine mesopores were basically preserved during activation, while the micropores were generated within the mesopore wall in large quantities.
