This period was followed by a state of low responsiveness with the period of transition ranging between 75 to 90 minutes after birth.
The effect of this autoregulatory behaviour is that sufficiently high exogenous LIF maintains pathway responsiveness, i.e. the "on" state, whereas low concentration or no exogenous LIF cause ESCs to adopt a state of weak responsiveness, i.e. "off" state.
Our results show that cells pass from a state of high responsiveness to N-pathway activation (up to 50%) during the first 60 minutes of life to a low, no null, responsiveness state (under 50%) with a period of transition around 60 to 75 minutes after birth.
3, 4 Insulin resistance is a state of reduced responsiveness to normal levels of this hormone.
A critical point is that the inherent noise from the firing of neural populations acts first to allow a state of rapid responsiveness to inputs.
The child remained stable albeit in a state of minimal responsiveness, with no communication or purposeful movement until she died of a respiratory illness in March 2004, two and a half years after her diagnosis.
We indicated that this ITC-derivative enhanced intracellular platinum accumulation and conferred the cells a state of increased responsiveness to cisplatin-induced apoptosis associated with alterations in cell cycle protein regulation, glutathione (GSH) levels, caspase-3 activation, mitochondrial potential and signalling pathways including MAPKs family members.
These observations, coupled with the fact that we found no evidence of T cell deletion, suggest that HPCs may induce a state of non-responsiveness by inducing Tregs.
Since TCR+ cells circulate between placenta and periphery, we speculated that this down-regulation would be reversible, to allow the maternal immune system to respond to other antigenic challenges whilst maintaining a state of non-responsiveness against the fetus.
Their vividness conveys a state of attentiveness and responsiveness to which ordinary consciousness, in its distraction and world-weary fatigue, rarely rises.
