It has been found, however, that reduced radiation increases the synthesis of chlorophyll (Lopes et al., 2017), which may contribute to an increase in PpIX in plants that receive carfentrazone-ethyl.

Tumors presenting only one feature were evaluated for invasiveness through the Met-PET study, demonstrating that the tumor showing a much larger Met-uptake area than the Gd-enhanced area was highly invasive [22, 23] or had a higher fluorescence intensity of PpIX of the brain in the resection cavity.
first found this phenomenon when they used GNP as vehicle to transport a photosensitizer PpIX .
Data from a retrospective study showed that cooling pain relief, with an air-cooling device during treatment, resulted in lower PpIX photobleaching in AK lesions, compared with no cooling (J Photochem Photobiol B.
PpIX from ALA and Verteporfin are accumulated mainly in mitochondria and plasma membrane.

Daylight PDT (dPDT) is a novel approach that delivers continuous low-level activation of protoporphyrin IX (PpIX) for the treatment of photoaged skin and actinic keratoses.
One of the most widely used photosensitisers for the FD for brain tissue is 5-aminolevulinic acid (5-ALA) which induces elevated protoporphyrin IX (PpIX) production in malignant cells.
The biosynthetic process of converting 5-aminolevulinic acid (ALA) into protoporphyrin IX (PpIX) is part of the overall energy producing system of cells.
The analytical results for EP were calculated on the basis of a millimolar absorptivity for protoporphyrin IX (PPIX) of 241.
Many of the currently clinically employed photosensitizers are based on porphyrin molecules such as Photofrin, a hematoporphyrin derivative, and 5-aminolevulinic acid (ALA), a precursor of protoporphyrin IX (PpIX).
