Best's vitelliform macular dystrophy

, : Best's vitelliform macular dystrophy. American Journal of Ophthalmology 79(1): 59-66

A patient with Best's vitelliform macular dystrophy in his right eye had an intact vitelliform disk and drusen of the optic papilla. Although the foveola elevated by a few tenths of a millimeter, resolution was only slightly affected and the retinal receptors remained remarkably well-aligned, suggesting that mechanisms subserving receptor alignment still functioned. Hue discrimination and visual acuity were only slightly affected and the electroretinogram and visually evoked response showed essentially normal values. The vitelliform disk in the left eye ruptured by direct, blunt trauma. This same eye later developed subretinal macular neovascularization, as its visual acuity reduced, retinal sensitivity decreased, receptor orientation showed abnormalities, and hue discrimination became less efficient; the electroretinogram and visually evoked response remained normal.

Nonnatural residues can endow proteins with desirable properties. Here, replacing a proline residue that has a cis peptide bond in native ribonuclease A with 5,5-dimethyl-l-proline is shown to accelerate protein folding by 6-fold and enhance confo...

Russia's sugar output in 1999 was substantially up on 1998 at 6,827,000 tonnes, of which 1,519,000 were from beet and 5,308,000 from imported raw sugar. External trade had thus become the basic source of supply. Domestic production of beet ha...
