The nonlinearity parameter B/,4 has been determined for solutions of bovine serum albumin, of dextrans, of sucrose, of hemoglobin extracted from blood, and for fresh whole blood. The value of B/,4 for solutions of bovine serum albumin has been observed to increase nearly linearly with concentration. Further, B/,4 appears to exhibit no dependence upon the molecular weight of dextrose and dextrans over the molecular weight range from 102 to 106.
The nonlinearity parameter B/,4 has been determined for various biological solutions and soft tissues using both the thermodynamic and finite amplitude methods. This letter is to show that agreement achieved between the two methods is within a fraction of a percent for liquid samples and within 10% for the soft tissues studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
