13. Confocal fundus imaging with a scanning laser ophthalmoscope in eyes with cataract.
AIMS/BACKGROUND--The study aimed to determine the influence of increased intraocular light scatter on the contrast in scanning laser ophthalmoscope (SLO) images and to examine to what extent SLO images can visualise the fundus through media opacities due to cataract. METHODS--Intraocular light scatter was estimated from measurements of letter contrast sensit

14. Structure of native alpha 2-macroglobulin and its transformation to the protease bound form.
Well-preserved structures of native and alpha-chymotrypsin-bound alpha 2-macroglobulin were obtained by electron microscopy. Computer processing of these images has shown that the native structure has the shape of a padlock 19 nm long. It is proposed that the native alpha 2-macroglobulin consists of the juxtaposition of two protomers with one protomer shaped
