For large "non-diffuse" bioenergy conversion systems (e.g., fermentation consisting of a few large-scale bioethanol plants), direct partnership with the plant operators is the ideal means for developing these specific conversion plant inventories (process-based mass and energy balances) [61].
The distribution of immunoreactivity for p473-Akt appeared to be unaltered by treatment, although in those later tumours of both treated and untreated groups that showed conversion to diffuse large B-cell lymphoma, Akt Ser473 phosphorylation reactivity was increased in tumour cells.
The use of more lipophilic derivatives of 5-aminolevulinic acid (ALA) is expected to have better diffusing properties, and after conversion into the parent ALA, to reach a higher protoporphyrin IX (PPIX) formation rate, thus improving the efficacy of topical photodynamic therapy (PDT).
Different approaches are currently under investigation to enhance ALA penetration, such as the application of ALA in various vehicles and the development of new synthetic molecules derived from ALA. Lipophilic derivatives of ALA were expected to have better diffusing properties, and after conversion into the parent ALA by enzymatic hydrolysis, to give a higher PpIX formation rate.
Conversion factors for diffuse components.
Conversion of a diffuse to a focal or variegated pattern is also frequent.
Conversion of a diffuse to a focal or variegated pattern is also frequent [ 40].
A conversion of a diffuse to a focal MR imaging pattern of marrow involvement, reduction, but not disappearance in lesion size and number, and persistant peripheral lesion enhancement on contrast-enhanced MR images (Fig. 6) have been described in association with a response to standard chemotherapy [ 58, 60].
More lipophilic derivatives of ALA were expected to have better diffusing properties, and, after their conversion into the parent ALA by enzymatic hydrolysis, to reach a higher PpIX formation rate.
The conversion of the hourly horizontal diffuse irradiation Dh to hourly diffuse irradiation DTh on the tilted surface ST can be expressed as D Th = r d D h, (10 where rd is the conversion factor.
