Rabbit corneal endothelial cells demonstrated an increase of endothelial membrane permeability to inulin following perfusion with 5 X 10(-6) M rose bengal and exposure to 1050 muW/cm2 incandescent light for either 1 min or 5 min when compared to corneas similarly perfused with rose bengal but not exposed to light. Endothelial permeability to dextran was unaltered following the photosensitizatio...

We investigated the role of singlet oxygen (generated from photoactivation of rose bengal) on the calcium transport and Ca(2+)-ATPase activity of cardiac sarcoplasmic reticulum (SR). Isolated cardiac SR exposed to rose bengal (10 nM) irradiated at 560 nm resulted in significant inhibition of Ca2+ uptake (from 2.27 +/- 0.05 to 0.62 +/- 0.05 mumol Ca2+/mg.min [mean +/- SEM], p less than 0.01) and...

Significant quantities of carbon soot aerosols are emitted into pristine parts of the atmosphere by marine shipping. Soot impacts the radiative balance of the Earth-atmosphere system by absorbing solar-terrestrial radiation and modifies the microphysical properties of clouds. Here we examined the impact of black carbon (BC) on net warming during monsoon season over southern Bay-of-Bengal, using...
