Deep-ultraviolet laser ablation sampling for proteomic analysis of tissue

Deep-ultraviolet laser ablation with a pulsed 193 nm ArF excimer laser was used to take away localized areas from tissue sections from which proteins have been extracted for spatially resolved proteomic evaluation by liquid chromatography tandem mass spectrometry (LC-MS/MS). The power to seize intact proteins by ablation at 193 nm wavelength was verified by matrix-assisted…

Impact of ultraviolet radiation on the retina

Mild has an important function within the visible course of. For nonvisible radiation within the short-wave spectrum, there are pure mechanisms that shield the human retina from damaging ultraviolet (UV) radiation. Right here, the dose (= power) makes the poison. Injury attributable to UV mild primarily impacts the outer retina, notably the photoreceptors and the…
