However, little information has been given about the mode of excretion or uptake of this compound in normal tissues.
Small quantities of the red waste compound, bilirubin (C33H36O6N4); a green product formed from it by the removal of two hydrogen atoms, biliverdin (C33H34O6N4); and various other chemically similar compounds occur in normal tissues and may be conspicuous in excretory or secretory materials under normal circumstances and certain pathological conditions.
Hairy roots can in many cases produce the same compounds found in normal roots of the parent plant, but while in callus or cell suspension cultures this productivity frequently diminishes over time it remains stable in transformed roots [18].
MALDI-IMS under various forms has already been successfully used to characterize the expression of proteins and other organic biological compounds in numerous normal and diseased tissues (Chaurand et al. 2005).
Thin sections were examined with a Leica DMLP compound microscope in normal transmitted light and cross-polarized light.
Thin sections were studied with a Leica DM EP® compound microscope in normal transmitted and polarized light.
NAA and creatine decreases were most significantly correlated with the total lesion volume (P < 0.01), suggesting that these compounds are present in normal brain only.
The concentration of these compounds was tested in normal physiological conditions, during starving and liver damage [ 60, 61].
Choline-containing compounds differentially accumulate in normal and malignant tissue, and have been localised, as shown in in vivo 1 H MR spectroscopy of brain tumours (Vigneron et al, 2001) prostate cancer (Kurhanewicz et al, 1996) and breast cancer (Kvistad et al, 1999).
In the present study, the degree of selectivity of the synthetic compounds is expressed as per the previous reports [36, 37]: SI = IC50 of pure compound in a normal cell line/IC50 of the same pure compound in cancer cell line, where IC50 is the concentration required to kill 50% of the cell population.
