Developing an optical backscatter method for determining casein micelle particle size in heated milk.

A plethora of different factors, such as heat treatment, pH, soluble calcium and phosphate concentrations, colloidal calcium phosphate, ionic strength, redox potential, etc., affect functionally of critical milk components such as casein micelles, fat globules and whey proteins. These physicochemical changes induce fat- or protein-protein interactions that would be associated to changes in particle size that might be revealed using light backscatter measurements.

Symblepharon repair using a silicone sheet implant.

A technique utilizing a thin silicone sheet and a polyethylene tube to surgically repair symblepharon is described. A summary of cases treated by this technique is reviewed and other areas for further study are discussed.
