Effects of Collagen and Collagen Hydrolysate from Jellyfish (Rhopilema esculentum) on Mice Skin Photoaging Induced by UV Irradiation

“…It has been known that approximately 50% of UV‐induced damages in skin are from the formation of reactive oxygen species (ROS) (Jessica and others 2000), such as superoxide anion radical (·O −2 ), hydrogen peroxide (H 2 O 2 ), hydroxyl radical (·OH), and singlet oxygen ( 1 O 2 ). Therefore, free radical scavengers and antioxidants, such as tea polyphenols (Lu and others 2002), Ve (Mccay 1985), and ß‐carotene (Lee and others 2002) could alleviate the oxidative stress UV‐induced in vivo . Normally, endogenous antioxidant enzymes are able to efficiently scavenge the formed ROS to protect skin from the injury (Chance and others 1979).…”

Two-Dimensional Miscibility StudiesThe Analysis of Interaction between Long-Chain Alcohols and Semifluorinated Alkanes

“…Dipalmitoylphosphocholine (DPPC)a well-known model lung surfactantis always administered with cosurfactants, like hexadecanol and tyloxapol and, therefore, has been investigated in many different kinds of mixed films, for example, in mixtures with long-chained alcohols or cholesterol. , The antibacterial or antifungal activity of many antibiotics is strongly related to their interaction with bacterial or fungal cell membrane components, and therefore, a great number of monolayer studies of binary or ternary systems containing an antibiotic molecule and a cell membrane component have been carried out, e.g., mixures of valinomycin with cholesterol and stearic acid, bacteriocin and a phospholipid, amphotericin B and different sterols, or gramicidin A and ethyl palmitate . Other research projects involve studies of ceramides in mixed films with cholesterols and fatty acids, , mixtures of modified vitamins, or an anticancer drugmiltefosinemixed with a model ganglioside or membrane phospholipids …”
