The evolutionary patchwork nature of the light reactions of photosynthesis in plants provides ample scope for their improvement, particularly with respect to its light-harvesting components and the susceptibility of photosystems to photodamage. Such improvements can be achieved by genetic engineering and, more indirectly, by conventional breeding, whereas synthetic biology should allow in the l...
Sulfated polysaccharides isolated from seaweeds are thought of as ideal ingredients in the pharmaceutical, nutraceutical, and cosmetics industries. Our previous study characterized sulfated Padina boryana. The boryana (PBP) were extracted, antioxidant activity PBP was evaluated. results indicate that possesses effects potential cosmetic industry. To further investigate cosmetics, photoprotectiv...
The recently developed technique of two-photon fluorescence microscopy causes much less photodamage than conventional confocal microscopy, expanding the possibilities for imaging living specimens.
BACKGROUND AND AIM Ingenol mebutate (IngMeb) is an effective treatment for actinic keratosis. In this study, we hypothesized that repeated treatments with IngMeb may prevent progression of UV-induced photodamage, and that concurrent application of a corticosteroid may reduce IngMeb-induced local skin responses (LSR). METHODS Hairless mice (n = 60; 3 groups of 20 mice) were irradiated with sol...
The primary reactions in photosynthesis take place in the reaction centers surrounded by light harvesting complexes (Blankenship, 2002; Diner and Rappaport, 2002; Frank and Brudvig, 2004). There are two types of photosynthetic reaction centers. The type I reaction center has ironsulfur cluster as stable electron acceptor, such as photosystem I complexes, green bacterial and heliobacterial react...
