Hematoporphyrin derivative (HpD) is a systemically administered photosensitizing agent that may be of value in the treatment of solid tumors. When corneal endothelial cells were perfused in the specular microscope with HpD and exposed to a 25-W incandescent light at 5 cm (5.5 mW/cm2) there was anatomic disruption of corneal endothelial cells and swelling of the corneal stroma. Perfusion with 0....

Title of Document: Investigating the mechanism of the hydrogen peroxide photoproduction from chromophoric dissolved organic matter Yi Zhang, Doctor of Philosophy, 2014 Directed By: Professor Neil Blough Department of Chemistry The photochemical pathways for H2O2 production from chromophore dissolved organic matter (CDOM) were investigated extensively, employing in part a selective sodium borohy...

We evaluate herein the impact of positive charge distribution on the in vitro and in vivo properties of Mn porphyrins as redox modulators possessing the same overall 5+ charge and of minimal stericity demand: Mn(III) meso-tetrakis(trimethylanilinium-4-yl)porphyrin (MnTTriMAP(5+)), Mn(III) meso-tetrakis(N,N'-dimethylpyrazolium-4-yl)porphyrin (MnTDM-4-PzP(5+)), Mn(III) meso-tetrakis(N,N'-dimethyl...

Nitroxides are the most important metal-independent superoxide dismutase mimics. They act as antioxidants mainly by reacting with superoxide. Nitroxides are low molecular weight, cell membrane permeable, and relatively stable radicals. The SOD-mimic activities of nitroxides are catalytic processes in which nitroxides and their oxidized form exchange among themselves without depletion of nitroxi...

Organic amine-based buffer compounds such as HEPES (Good's buffers) are commonly applied in experimental systems, including those where the biological effects of peroxynitrite are studied. In such studies 3-morpholinosydnonimine N-ethylcarbamide (SIN-1), a compound that simultaneously releases nitric oxide (.NO) and superoxide (O-2), is often used as a source for peroxynitrite. Whereas in mere ...

A battle is raging over the molecular identity of the voltage-gated, H -selective conductance that has been recorded in activated and/or depolarized phagocytes. Having stepped out of this arena, we feel uncommitted to any particular viewpoint and hope to be able to provide below an unbiased opinion of what we feel has been established unambiguously, and what requires additional confirmation bef...

Hypothermic perfusion of the heart decreases oxidative phosphorylation and increases NADH. Because O(2) and substrates remain available and respiration (electron transport system, ETS) may become impaired, we examined whether reactive oxygen species (ROS) exist in excess during hypothermic perfusion. A fiberoptic probe was placed on the left ventricular free wall of isolated guinea pig hearts t...
