Use of Dimethyl Sulphoxide for Preserving Corneal
SINCE it was discovered by Polge, Smith, and Parkes (1949) that living cells could be protected during freezing and thawing by adding glycerol to the storage medium, various substances and methods have been used in an attempt to achieve better results (Fleming,: 1952; Eastcott, Cross, Leigh, and North, 1954; Lovelock, 1954). We have been concerned with retaining the viability of corneal tissue ...

interactions which can be done when more structural information is available, but they do provide order of magnitude estimates of interaction strengths. Evidently, considerable rearrangement of charge driven by reduction significantly raises the effective dielectric. It seems likely that centres S-2 and FR-2 are apparently low-potential clusters merely because they are the middle clusters in th...
متن کاملSynthesis of Enaminones and Their Reaction with Dimethyl Acetylene Dicarboxylate
In present paper a simple procedure for the synthesis of enaminones without catalyst from 1,3-diketones that reacted with primary or secondary amines in ethanol as solvent, as well as the reaction of enaminones with unsaturated esters such as dimethyl acetylene dicarboxylate are reported.
متن کاملReaction of myoglobin with 3,3-tetramethyleneglutaric anhydride.
1. The extent of reaction of the protein with 3,3-tetramethyleneglutaric anhydride was measured by determining the loss of lysine and the equivalent appearance of 3,3-tetramethyleneglutarimidolysine in the hydrolysate at various time-intervals. Of the 19 lysine residues in sperm-whale myoglobin, three did not react with 3,3-tetramethyleneglutaric anhydride. Also, the N-terminal valine did not r...
