Biorheology is an international interdisciplinary journal that publishes research on the deformation and flow properties of biological systems or materials. It is the aim of the editors and publishers of Biorheology to bring together contributions from those working in various fields of biorheological research from all over the world. A diverse editorial board with broad international representation provides guidance and expertise in wide-ranging applications of rheological methods to biological systems and materials.

The aim of biorheological research is to determine and characterize the dynamics of physiological processes at all levels of organization. Manuscripts should report original theoretical and/or experimental research promoting the scientific and technological advances in a broad field that ranges from the rheology of macromolecules and macromolecular arrays to cell, tissue and organ rheology. In all these areas, the interrelationships of rheological properties of the systems or materials investigated and their structural and functional aspects are stressed.

The scope of papers solicited by Biorheology extends to systems at different levels of organization that have never been studied before, or, if studied previously, have either never been analyzed in terms of their rheological properties or have not been studied from the point of view of the rheological matching between their structural and functional properties. This biorheological approach applies in particular to molecular studies where changes of physical properties and conformation are investigated without reference to how the process actually takes place, how the forces generated are matched to the properties of the structures and environment concerned, proper time scales, or what structures or strength of structures are required.

Biorheology invites papers in which such 'molecular biorheological' aspects, whether in animal or plant systems, are examined and discussed. While we emphasize the biorheology of physiological function in organs and systems, the biorheology of disease is of equal interest. Biorheological analyses of pathological processes and their clinical implications are encouraged, including basic clinical research on hemodynamics and hemorheology.

In keeping with the rapidly developing fields of mechanobiology and regenerative medicine, Biorheology aims to include studies of the rheological aspects of these fields by focusing on the dynamics of mechanical stress formation and the response of biological materials at the molecular and cellular level resulting from fluid-solid interactions. With increasing focus on new applications of nanotechnology to biological systems, rheological studies of the behavior of biological materials in therapeutic or diagnostic medical devices operating at the micro and nano scales are most welcome.

An approximate Casson fluid model for tube flow of blood

Authors: Walawender, Walter P. | Chen, Te Yu | Cala, David F.

Article Type: Research Article

Abstract: An approximate Casson model for tube flow is derived based on order of magnitude considerations. The approximation is principally of value for tube flow measurements in which the pressure drop and volumetric flow rate are experimentally measured. Data for heparinized bovine blood and silica suspensions are in good agreement with the approximate expression. The model is compared with an approximation proposed earlier by Merrill et al .

A coiled capillary viscometer for blood

Authors: Walawender, Walter P. | Chen, Te Yu | Cala, David F.

Article Type: Research Article

Abstract: This report provides a description of a coiled capillary viscometer with a continuously varying pressure head and the theory behind its operation. Flow curves are presented for whole bovine blood and aqueous silica suspensions. The data are compared with results from a true bore capillary viscometer as well as with the generalized friction factor correlation of Metzner and Reed. Favorable results were obtained for a shear stress range from 0.1 to 16 dyn/cm2 .

Effet du mouvement induit des hématies sur le transport plaquettaire

Authors: Antonini, G. | Guiffant, G. | Quemada, D.

Article Type: Research Article

Abstract: L’augmentation du transport des plaquettes sous l’effet de la rotation induite des hématies dans du sang en écoulement est abordée au moyen d’une analyse en terme de diffusion convective. Cette approche permet d’obtenir un coefficient de diffusion effectif pour les plaquettes qui dépend du cisaillement et dont la valeur est en bon accord avec des résultats expérimentaux récents. On discute la possibilité d’application de ce processus à l’étude du transport d’autres expèces peu diffusives (protéines, urée, oxygène... ).

Rheopexy of denatured bacterial DNA solutions

Authors: Uhlenhopp, Elliott L.

Article Type: Research Article

Abstract: Solutions of denatured DNA obtained by lysing Bacillus subtilis bacteria at pH 12.5 exhibited time-dependent increases in viscosity, recoil, and retardation time (rheopexy), as measured by a Cartesian-diver rotating-cylinder viscoelastometer. The degree of rheopexy depended on DNA concentration, solvent viscosity and shear stress, but was relatively insensitive to temperature. Of the three viscoelastic parameters measured, recoil was the most sensitive indicator of rheopexy, viscosity moderately sensitive and retardation time the least sensitive. The rheopectic transitions were attributed to temporary, reversible, shear-induced aggregation of single-stranded DNA molecules.
