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: A sedimentation recorder including an optical tracking head controlled to track the liquid-solid separation boundary in a tube containing a sample of liquid-solid mixture is described. The tracking head is controlled by a pulse operated servomotor which responds to the output of a photodetector mounted in the tracking head. A two-pen plotter is provided to record the sedimentation behavior of the sample. One pen is connected to the tracking head and continuously records the position of the liquid–solid separation boundary to provide a settling curve. The other pen is driven by a rate of change mechanism and records the approximate…rate of change of the separation boundary position. The rate of change mechanism operates by measuring the excursion of the tracking head during each of a series of successive time intervals. The difference between each excursion measurement and the preceding measurement is calculated and each difference value is converted into a corresponding number of pulses. The pulses are applied to drive a second pulse operated stepping motor which in turn drives the rate of change recording pen. The approximate cost of construction of this unit is $1800.
