The spectrally and temporally resolved fluorescence properties of native bacteriorhodopsin (bR) and bR reconstituted with a nonisomerizing analog of the retinal Schiff base (bR5.12) are examd. The first attempt to exptl. monitor the excited state relaxatio ...
We present mol. dynamics simulations of bovine rhodopsin in a membrane mimetic environment based on the recently refined x-ray structure of the pigment. The interactions between the protonated Schiff base and the protein moiety are explored both with the c ...
Information on the temporal order, the kinetics, and the energetics of each of the reaction intermediates is required in order to fully elucidate the mechanism of catalytic interaction of G proteins with their receptors. Intrinsic monitors, such as light s ...
OBJECTIVE: To evaluate the safety and short-term visual and fluorescein angiographic effects of a single photodynamic therapy treatment with verteporfin with the use of different dosage regimens in patients with choroidal neovascularization (CNV) from age- ...
BACKGROUND: Conventional photocoagulation of subfoveal choroidal neovascularization (CNV) is often accompanied by visual loss due to thermal damage to adjacent retinal structures. Photodynamic therapy (PDT) allows vascular occlusion by selective photochemi ...
Objective: To evaluate short-term safety and the effects on visual acuity and fluorescein angiography of single or multiple sessions of photodynamic therapy with verteporfin for choroidal neovascularization (CNV) not related to age-related macular degenera ...
