Any tissue-engineering approach to regeneration must involve a source of cells, which will ultimately fill the defect.
The experiment involved a source consisting of a 0.0096-g active matrix of 68Ge/68Ga that had been mounted towards the base of a gamma counter compatible, 12-mm-diameter, 75-mm-long plastic rod (model BM08, RadQual, Weare, NH, USA).
The practice of finning is unacceptable from the environmental point of view, because it threatens the sustainability of some shark species targeted by this practice, from the social and economic point of view, because it involves squandering a source of food with commercial value, and also from the moral point of view, because it shows a total disrespect for animal life.
The experimental design constrains interpretation of the results: they suggest that some aspect of human consciousness is involved as a source of the effects.
Furthermore, significant ns SNPs were detected in the genes encoding LigC and MutT2, and MutT2 has already been suggested to be involved as a source of variation in w-Beijing strains (13).
However, the oxygen sensor or sensors that activate this sequence, and the ion channels and signal transduction pathways involved, remain a source of much scientific controversy (Aaronson et al, 2006).
The time-frequency-based method would involve an external source of excitation.
The nonshiftable activities might involve an additional source of opportunity costs because it must be provided at specific moments or times of the day.
The case reported here involved an occupational source of such an exposure (aerosolized metalworking fluid in a machining environment), although aerosols containing mycobacteria have been described in other settings as well (aerosolized water from hot tubs).
Propagation of a typical infrared radiation involves a variety of sources of different sizes, shapes, intensities, roughness, temperature, etc., all of which would impose impacts on the fidelity of the synthetic images.
