A more subtle form of extinction, genetic extinction in which the unique genome of a native taxon is lost through hybridization with closely related invaders has also been demonstrated, particularly in fish (Lockwood et al. 2007).
The direct co-stimulation of tumor-specific effector CD4+ and CD8+ T cells (Teffs) has been demonstrated, particularly in combination with active vaccination [16], [17], [19]; yet, the in vivo effects of DTA-1 on Tregs have not been well-defined.
Indeed, a close relation between PV rich fiber plexuses in layers IV and deep layer III and afferents from PV dominant thalamic nuclei has been demonstrated, particularly in the auditory system (Jones 2003).
Indeed, a significant age-related reduction in serum total and free T3 levels has been demonstrated, particularly in nonagenarians, whereas serum total and free T4 concentrations did not show any correlation with age [ 2].
The importance of this approach has been demonstrated particularly in dialysis patients, in whom rigorous limitation of salt intake and aggressive ultrafiltration were shown to prevent or reduce LV hypertrophy and dilatation, with little or no antihypertensive medication [ 71, 72].
Indeed, it has been shown that involvement of consumer and community groups early in projects improves uptake by consumers, and this has been demonstrated particularly in projects involving the use of sunscreens, cancer screening programs, smoking cessation programs, and in the treatment of asthma [ 21- 26].
Although the creatinine value is highly specific to estimate renal dysfunction, an inadequate sensitivity of creatinine level is demonstrated, particularly in early stage AKI.
However, the respective efficacy of these measures and of their combinations remains to be demonstrated, particularly in countries of high and intermediate TB endemicity [11].
To attempt control, and possibly elimination, of zoonoses, benefits to public health and society need to be demonstrated, particularly in countries with scarce resources.
So despite the logical value of performing it in critically ill and injured patients, many have argued that a true value cannot be demonstrated, particularly in children [ 20, 23, 26, 31].
Gravity dependent changes in ΔZV/ΔZQ could be demonstrated (particularly in lateral positions), similar to those found using other measurement techniques with greater spatial resolution such as electron-beam CT [ 17] or radio-labelled tracers [ 18].
