Catecholaminergic polymorphic ventricular tachycardia (CPVT) and long QT syndrome (LQTS) are ion channelopathies of genetic origin characterized by life-threatening ventricular arrhythmias, which are triggered by increased sympathetic activity, for example, physical exercise and emotional stress.
Ashley may have taken exception to the Record's coverage, viewing it as sympathetic to King (example here), but he hasn't made any statement to that effect.
For example, sympathetic cooling of an ion with mass ∼100 amu is most efficient with a neutral mass of ∼40 amu and leads to an ion with a steady-state energy roughly 3× that of the neutral atoms.
For example, sympathetic vasomotor tone has been shown to be tightly regulated by chemoreflex mechanisms.[35] Furthermore, MSNA is substantially increased in patients with obstructive sleep apnea [36], [37] and in patients with chronic obstructive pulmonary disease[38].
For the example sympathetic efferent fiber in Fig. 2A, the conduction latency increased during the first 100 pulses, but approached a plateau level for subsequent pulses (Fig. 2B); the final increase in latency was 12.9 ms which corresponded to an 8.7% increase in conduction latency.
"Formation of each the NC-derived sympathetic ganglia, for example, relies on the scattered NC cells self-aggregating…" Please delete "the" from this statement.
Formation of each the NC-derived sympathetic ganglia, for example, relies on the scattered NC cells self-aggregating, driven innately by increased N-cadherin homophilic adhesion.
For example, sympathetic hyperarousal has been detected in insomniacs, as evidenced by increased heart rate, heart rate variability, metabolic activation, and activation of the sympathetic nervous system during sleep [ 17- 19].
In conclusion, one can speculate that sympathetic neurotransmitters (for example, NE) alter chondrogenic differentiation of chondrogenic progenitor cells by inhibiting chondrocyte hypertrophy via β-ARs during embryonic endochondral ossification.
As a side note, there is a direct interrelation between the SNS and the sensory nervous system, since the sensory response is significantly modulated by sympathetic signaling (for example, [ 27]).
