Abstract

A computer controlled wrist joint motion simulator has been developed that actively moves forearms from cadavers through cyclic planar flexion-extension motions, planar radial-ulnar deviation motions, and combined motions such as circumduction. Hybrid position-force feedback control algorithms are used to determine the wrist flexor and extensor tendon forces necessary to achieve the desired motions. The simulator was used in a series of 12 fresh cadaver forearms to produce both flexion-extension and radial-ulnar deviation motions and was found to cause repeatable, physiological movements. In these experiments, the extensor tendon forces were greater than those of the flexors, typically by a factor of two.

Why forces between proteins follow different Hofmeister series for pH above and below pI.

The relative effectiveness of different anions in crystallizing proteins follows a reversed Hofmeister sequence for pH pI. The phenomenon has been known almost since Hofmeister's original work but it has not been understood. It is here given a theoretical explanation. Classical electrolyte and double layer theory deals only with electrostatic forces acting between ions and proteins. Hydration and hydration interactions are dealt with usually only in terms of assumed hard core models. But there are, at and above biological salt concentrations, other non-electrostatic (NES) ion-specific forces acting that are ignored in such modeling. Such electrodynamic fluctuation forces are also responsible for ion-specific hydration. These missing forces are variously comprehended under familiar but generally unquantified terms, typically, hydration, hydrogen bonding, pi-electron-cation interactions, dipole-dipole, dipole-induced dipole and induced dipole-induced dipole forces and so on. The many important body electrodynamic fluctuation force contributions are accessible from extensions of Lifshitz theory from which, with relevant dielectric susceptibility data on solutions as a function of frequency, the forces can be extracted quantitatively, at least in principle. The classical theories of colloid science that miss such contributions do not account for a whole variety of ion-specific phenomena. Numerical results that include these non-electrostatic forces are given here for model calculations of the force between two model charge-regulated hen-egg-white protein surfaces. The surfaces are chosen to carry the same charge groups and charge density as the protein. What emerges is that for pH pI (where anions are co-ions) the forces increase in the order NaCl<NaI<NaSCN. This is in excellent agreement with both solubility experiments and experiments using SAXS. The results are also consistent with cation effects observed in protein solutions. Our results may provide some insights into a long-standing problem in solution chemistry and biology.

Microtensile testing of collagen fibril for cardiovascular tissue engineering.

As a candidate scaffold material for cardiac tissue engineering, Type I collagen material shows different mechanical properties due to the differences in the structural features such as orientation of fibril alignment and the environmental factors such as ultraviolet (UV) irradiation. In this article one-dimensional tensile stress tests were performed with the use of a nanoscale tensile tester on four groups of Type I collagen samples that were differentiated in terms of fibril orientation and/or UV irradiation. The collagen surface structure was studied with the use of an atomic force microscope (AFM). Effects of fibril orientation and UV irradiation on their mechanical properties were investigated. The mechanical properties and deformation mechanisms are discussed in conjunction with collagen structure, fibril orientation, and dispersion of the generated crosslinking by UV irradiation.
