    (a) Depiction of the overall structure of the CPD photolyase from Anacystis nidulans in complex with DNA (repaired thymine dimer in purple) and cofactors (FAD in green, 8-HDF in orange). PDB 1TEZ (b) Depiction of the overall structure of the CPD photolyase from Methanosacina mazei in complex with DNA (thymine dimer in purple) and FAD cofactor (green). PDB 2XRZ

    RESEARCH ARTICLE: Why is Rose Bengal More Phototoxic to Fibroblasts In Vitro Than In Vivo?

    Rose Bengal photosensitization of fibroblasts grown in collagen gels and monolayers. (A, B) Fibroblasts cultured in collagen gels (A) or as monolayers on plastic (B) for 24 h, then treated with various concentrations of RB in PBS for 1 min, washed and irradiated with 532 nm light. Cell viability was assayed 24 h later and percent viability calculated relative to unirradiated controls. (C) Monolayer fibroblasts were treated RB to produce the same intracellular RB concentration (0.46 mm), then split and cultured in collagen gels or as monolayers for 24 h before irradiation. Cell viability was measured 24 h later. Values are the mean ± SD.

    INVITED REVIEW: Visualizing Carbene Equilibria

    UV–Vis spectrum acquired 80 ns after LFP of phenylbromodiazirine with 0.10 m TBABr in DCE (after calibration). Absorptions of PhCBr are at 316 and 620 nm; absorption of PhCBr2− is at 428 nm. Reprinted with permission from ref. , copyright 2012, American Chemical Society.

    The difference between the absorbance of the mixture and the cumulative absorbance of the individual components, ΔA(λ), is reported for increasing additions of 4′-cisDPyP to a 4.3 × 10−7 m toluene solution of ZnP2. In the inset the change of absorbance at 433 nm is shown with the fitting according to Eq. (1).
