Photodynamics of the bacteriochlorophyll-carotenoid system. 1. Bacteriochlorophyll-photosensitized oxygenation of beta-carotene in acetone.

Carotenoids are well-known physical quenchers of chlorophyll excited states and reactive oxygen species both in vivo and in vitro. They may also be involved in chemical quenching undergoing, e.g. isomerizations or oxidations. We have found that beta-carotene (Car) in aerobic acetone is rapidly oxygenated under strong illumination with red light (lambda exc > or = 630 nm) in the presence of bact...

Mercury-photosensitized reactions

Hg Photosensitization reactions have selectivity for volatile molecules which allows partial oxidation of alkanes and selective dehydrodimerization of a wide variety of organic molecules. Hg photosensitization via the 3P1 state (Hg') allows the dehydrodimerization and functionlization of a variety of volatile organic molecules on a 1 to 50g scale in standard laboratory photochemical equipment a...

Skin protection for photosensitized patients.

BACKGROUND AND OBJECTIVE The goal of this study was to evaluate various creams for their capability to protect photosensitized skin from visible light. STUDY DESIGN/MATERIALS AND METHODS Two cover creams and creams containing various combinations of Vaseline with TiO(2), ZnO, and Fe(2)O(3) were used to measure the reduced light transmission and the light absorption spectrum. In vitro and in v...

Urinary imidazoles in rheumatoid arthritis.

This is a study of a small group of patients with rheumatoid arthritis, in whom the urine excretion of imidazole compounds was examined by Figlu assay and chromatography of 12-hour urine collections following 15 g. histidine load, and by assay of 4 amino-imidazole-5 carboxamide (AIC) in 12hour urines with and without histidine load. Gough, McCarthy, Read, Mollin, and Waters (1964) found low ser...

Photosensitized one-electron oxidation of DNA*

Photosensitized one-electron oxidation of DNA has attracted much interest because it causes oxidative damage which leads to mutation, and because it is involved in the basic mechanism of photodynamic therapy. In the present article, we describe the mechanistic study of photosensitized DNA damage, especially addressing the kinetics of hole transfer by adenine(A)-hopping and its effect on the DNA...
