Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in distinct areas to commonly occurring diseases. According to different angles of the acting chewing force, ...

Articular cartilage is an avascular connective soft tissue in the diarthrodial joints and functions in a highly demanding mechanical environment. The degeneration or wear of the cartilage is a huge problem that effects millions of people every year. The long term objective of the present work is to develop an analytical articular cartilage growth model. A simplified 2D axisymmetric ...

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak current. The biosensor is constructed by immobilizing redox-enzyme on an interdigitated array (IDA) electrode ...

We address the use of magnetic fields, forces, and materials for medical purposes. In particular, the treatment of osteochondral lesions is aimed for. To support ongoing activities in this field of research, last advances in using Finite Element Analysis (FEA) for the simulation of relevant processes, like magnetic targeting and magnetic fixation are reported. The availability of advanced ...

In the present study we determined the relative conductivities and permittivities of fresh cortical and cancellous bone measuring human femoral heads in different slices of 1 mm thickness. The identified conductivities of human trabecular bone are used for the electromagnetic field simulation by means of COMSOL using a Micro-Computed Tomography (Micro-CT) model. The calculated model depends on a ...

Polymer gels belong to the realm of soft active materials as they are capable of responding to a non-mechanical stimulus – the permeation of a solvent – with a mechanical action – a volume change, thanks to the coupling between different physics. This mechanism of coupling can be exploited in a wide range of applications, including biomedical devices, making crucial the understanding of the ...

There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies suggest that the protective effects of post-conditioning relate to the dynamics of blood flow. COMSOL is being ...
