This is because antigen-specific B lymphocytes take up antigen for presentation to T cells and, by doing so, create a self-sustaining circuit of B and T cells through which other naïve T cells may be recruited.
The increased digital control may reflect a necessity of enhanced engagement of small regulatory circuits for sustaining cellular metabolism and growth, because the loss of global DNA architectural factors FIS and H-NS impairs the function of the overarching network of nucleoid-associated proteins and topoisomerases in regulating the supercoiling response of transcription [ 18].
These cells, in turn, activate more self-reactive T cells to produce proinflammatory cytokines which sustain this pathologic circuit.
The simplest genetic circuit capable of producing sustained oscillations is a circuit of one gene with delayed self-inhibiting regulation.
Expression of GHS-R1A in islet endothelial cells, together with the established production of ghrelin within pancreatic islets [ 3, 34], may sustain the autocrine/paracrine circuits active between endocrine and endothelial counterparts within the islet of Langerhans [ 14].
Honda was the circuit's biggest-spending owner; sustaining its two-car race team cost the company an estimated $217 million in 2008.
In conclusion, Hou et al. have elegantly demonstrated that a dual circuit mechanism may be responsible for sustaining differential hypoxia in patients receiving peripheral VA-ECMO.
Collectively, the findings from human and animal studies provide the basis for a relatively precise description of the neuronal circuits mediating sustained attention, and the dissociation between these circuits and those mediating the 'arousal' components of attention.
Minimizing your contact with electrical circuits drastically reduces that chances of sustaining burns or injury.
Using a small signal simulation model and a suitable thermal model, intra pulse diode susceptance are computed and from the sustained oscillation condition, the circuit susceptance presented at the device terminal is calculated and frequency chirp bandwidth is estimated.
