Globally in Otolaryngology industry, Sinusitis is one of the most common diseases related to the nose. Sinusitis is caused when the cilia fail to move the mucus. As a result sinus tissue gets infected that leads to blockage of the sinuses. All the sinusitis can not be cured through drugs and certain require surgery. When a sinus cavity subjected to a nasal endoscopic surgical procedure, one of ...

Musculoskeletal mineralized tissues (MMTs), e.g. bone, are hierarchical composite materials. Their effective elastic properties at different scales are of interest for computational studies of the MMT’s response to mechanical loading but also to realistically simulate implant osseointegration. We combine multi-scale and multi-modal experimental techniques with mathematical modelling of MMTs ...

The design challenge for thermostimulation equipment is to get a combination of high electric field strength and high temperature within the muscle tissue without causing pain or skin burns. In the present work, COMSOL Multiphysics is used to simulate the temperature distribution and electric field distribution within body tissue for varying body composition and varying design parameters of the ...

Microbia Fuel Cells (MFC’s) are complex environments where electrochemical, physical and biological aspects must be considered together. In this work we present a 1D model partially describing a Shewanella oneidensis MFC that degrade sodium lactate [lactate -> Acetate + CO2 + 2H+ + 2e-]. The model, simulated using COMSOL, focuses on pH implications of the MFC operation. Release of protons during ...

Cholesterol is an essential lipid for human body. The desired total plasma cholesterol for an individual is less than 5.2 mM (200 mg/dL) and it poses a potential health threat when the level is greater than 6.2 mM (240 mg/dL) . Excessive plasma cholesterol causes poor cardiovascular conditions. The experimental fabrication of nano structured biosensor with advanced materials is more expensive ...

The mathematical modeling of the diffusion and reaction of toxic compounds in mammalian cells is tough task due to their very complex geometry. The heterogeneity of the cell, particularly the cytoplasm, and the variation of the cellular architecture, greatly affects the behavior of these toxic compounds. Homogenization techniques have been implemented for the numerical treatment of the model. ...

Drug therapy of the posterior part of an eye is very challenging. Yet, in USA alone, there are almost 2 million people affected by age related macular degeneration. When designing a strategy for controlled-release drug delivery, it is important to take into account of physiology, absorption, distribution, metabolism, and excretion properties of a drug. Therefore, the aims of this study are: 1) ...

Whilst initially developed as a diagnostic aid to improve echogenicity in ultrasound imaging, gas-filled lipid microbubbles are now emerging as a next generation \'theranostic\' tool in the medical arena. Here, their therapeutic potential has now been realized through their unique capability to deliver molecular species such as drugs and genes by means of disrupting the cell membrane in response ...

Patients undergoing surgery are sensitive to infections. The operation staff may spread 10^4 particles per person per minute, of which ten percent are presumed bacteria-carrying. We visualize the influence of the personnel on the air and particle flows for the two most common ventilation systems in Swedish hospitals using Comsol Multiphysics with particle tracing.. The Laminar Air flow ...
