Post-mortem water uptake by sheep lenses left in situ.
PURPOSE Human lenses are generally obtained from eye bank eyes, which have been stored in the cold for extended periods. It is not known what effect the storage has on the lens. In this study, we examine the effects of post mortem time on the weights of sheep lenses left in the eye. METHODS Lenses were removed from 299 ex vivo sheep eyes (200-day-old), which had been kept on ice for various t...
متن کاملFree and bound water in normal and cataractous human lenses.
PURPOSE To analyze free and total water in human normal and cataractous lenses. METHODS Thermogravimetric analysis was used to determine total water, and differential scanning calorimetry was used for free water. RESULTS In normal human lenses, the total water content of the nucleus remained unchanged with age, but the state of the water altered. The ratio of free to bound water increased s...
متن کاملSize-dependent lens angles for small oil lenses on water
Line tension is the excess energy associated with unit length of a three-phase contact line and it has long been of interest, in part because if sufficiently large, it can affect various processes of industrial and biological importance. Most recently, interest has centred on the magnitude and sign of experimentally determined values. Reported line tensions in systems with liquid alkanes in con...
متن کاملCrystallins in water soluble-high molecular weight protein fractions and water insoluble protein fractions in aging and cataractous human lenses.
PURPOSE The aim of the study was to comparatively analyze crystallin fragments in the water soluble high molecular weight (WS-HMW) and in the water insoluble (WI) protein fractions of human cataractous (with nuclear opacity) and age matched normal lenses to determine the identity of crystallin species that show cataract specific changes such as truncation and post-translational modifications. B...

Focus + context techniques are widely used for the efficient visualization of large data sets. However, the corresponding adaptation of the representation to the task at hand is not trivial, requiring a suitable model of the visualization goal. One type of focus + context technique is the use of lenses, interactive tools that modify the visualization in a locally confined region and can be ’sta...
