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.
Abstract: An earlier model of capillary tube viscometer was improved by (a) introducing a new indicating method, (b) increasing responsiveness through improved design and (c) eliminating some possible sources of error.

Abstract: Meniscal resistance to movement observed in a bubble in a capillary filled with an aqueous solution of a surface active agent grows with bubble length up to a maximum. Development of meniscal resistance requires a definite length of free wall. This finding is of interest in the study of foams, emulsions and suspensions.

Abstract: The deformability of red cells involves their elasticity, flexibility and internal viscosity. The viscosity of a dense pack of red cells involves not only red cell deformability but also intercellular friction. The results described in this paper are the product of a compromise method in which much but not all plasma has been removed before viscometry.

Abstract: The appearances of blood flowing at high velocities in fine blood vessels are discussed and are supported by high speed photographs and tracings from series of such photographs. These indicate that blood flowing in the larger arterioles contains loose aggregates or groups of red cells separated by zones of relatively cell free plasma. As these groups pass into the finer arterioles the blood cells become remarkably deformed and the diameter of the plastic masses, measured in the plane at right angles to the axis of the blood vessel, may be reduced to less than the diameter of a red…cell at rest. Discrete red cells are also deformed. It is suggested that such deformation of columns of flowing red cells accounts for the low relative viscosity of whole blood previously observed in fine glass tubes.

Abstract: In vitro tests on heparinized blood have shown that high molecular weight dextrans cause large increases in blood viscosity at low rates of shear. This may explain their deleterious effects on the perfusion of the capillaries in shock. Low molecular dextrans do not diminish blood viscosity below the control value. The experimental procedures employed constitute a rapid, simple method for testing in vitro the effects of plasma expanders on blood viscosity.
