One of the most extensively documented, but not well understood, consequences of direct nerve injury in animal models and human subjects is the subsequent increase of sensory neuron excitability, primarily manifested as spontaneous discharge and increased responsiveness to stimulation (Kajander and Bennett, 1992; Liu et al., 1999; Study and Kral, 1996; Zhang et al., 1997).
Although adherence has been extensively researched, it is not fully understood [ 22], and as CAM prevalence increases, its influence on adherence requires consideration.
Although the mechanisms whereby EPCs protect the cardiovascular system are still not fully understood, it has been extensively demonstrated that these bone marrow-derived cells contribute to endothelial repair and postnatal neovascularization [ 2, 3].
It's not as if the issues are not understood; they are articulately and extensively outlined in the APPGS report, but perhaps that's a testament to the low productivity of an All Party Parliamentary Group.
