...J.N. Liang The browning reaction (or advanced glycation) of calf lens α-crystallin generates chromophores which absorb light at wavelengths above 300 nm. They display an absorption shoulder above 300 nm, a positive circular dichroism band at 320–340 nm, and a blue fluorescence at 460 nm (Ex = 370...

...Gertrud Cremer-Bartels; O. Hockwin; Christa-Maria Schedtler Total fluorescence intensity of human lens extracts increases with degree of lens opacities. This fluorescence increase is not due to an increase of the phosphorylated pteridine like substance (PLS). Lens, human Cataract Fluorescence...

...Ran C. Zeimer; James M. Noth We propose a new method to measure in vivo nuclear transmittance using scanning photometry, thus complementing its present application in measuring lens scatter and fluorescence. We compared our method of measuring the transmittance with a previously reported in vivo...

... of a fluorophotometer, assuming an about equal fluorescence quantum efficiency in both parts. Consequently any difference in fluorescence between both parts can be attributed to a loss of exciting and fluorescent light in the lens. For both wavelengths, the average lens transmission is determined by this method...

...S. Lerman; O. Hockwin; V. Dragomirescu We are reporting a new, objective and quantitative method for monitoring age-related molecular changes in the human ocular lens in vivo, as expressed by increases in at least two (nontryptophan) fluorescence wavelengths. These data correlate with previously...

...S. Lerman; K. Gardner; J. Megaw; R. Borkman Exposure to ambient ultraviolet (UV) radiation (longer than 300 nm) over a lifetime appears to play a role in lens aging and nuclear cataract formation. The photochemical generation of fluorescent chromophores has been correlated with the increasing...

...Eui Fujimori Blue-fluorescent α-crystallin and a blue-fluorescent low molecular weight species have been isolated from calf lenses by gel-filtration on Sephadex G-200. This α-crystallin with considerable light-scattering has a single fluorescence maximum at 420 nm. The blue fluorescence of the α...

...R.C. Augusteyn Normal and cataractous lenses contain a highly fluorescent yellow protein which is insoluble in water but soluble in 7 m urea containing 0.01 m mercaptoethanol. The amount of this protein increases with the development of cataracts and this is accompanied by a decrease in the water...
