Examples

  • A 2004 study done by Harvard University scientists discovered that the pills dramatically decreased redness in the skin of human subjects.6 Another clinical test found that after oral administration of Polypodium leucotomos, there was increased photoprotection of immune Langerhans cells.7 The science behind this new antioxidant supplement is pretty solid, and, if taken correctly, it could help prevent sun damage.

  • "We found that patients with skin cancer who practice very good photoprotection (sun protection) have lower vitamin D levels," said Dr. Jean Tang, lead author of the study.

  • "We found that patients with skin cancer who practice very good photoprotection [sun protection] have lower vitamin D levels," said Dr. Jean Tang, lead author of the study.

  • "Most likely," said Tang, "the fact that skin cancer patients avoid sunlight is probably the number-one contribution to why they have low vitamin D levels, because the major difference between the two groups was that the skin cancer patients were practicing good photoprotection."

  • The main objective behind the use of this topical application is photoprotection in the case of organ transplant, to prevent skin and actinic keratosis.

  • The light-induced conformational altering of PBsome was also found in UV-treated PBsome from which a PE fluorescence increase has been observed, arising from the disassembly of PBsome components The photoprotection role of PE in the PBsomes of cyanobacteria on dissipating excess light energy to prevent the photodamage of RCs has been previously interpreted

  • On the other hand, assuming that the same process occurs also at the much lower physiological light intensities, our observations have important implications on the photoprotection function of PBsomes.

  • In addition to the roles in PBPs assembly and energy migration, the chromophoric γ subunit is preferentially sensitive to the intense light, and probably functions in the photoprotection of PBsome.
