A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the sensor using 2D full-wave electromagnetic analysis, and perform parametric studies of sensitivity as a function ...

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 ...

Singlet oxygen (1O2) is the major cytotoxic agent during photodynamic therapy (PDT). A previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic kinetic equations for the generation of the singlet oxygen, can be used to numerically calculate the distance-dependent reacted 1O2 using finite-element method (FEM). The formula of reacted ...

Erodible polymeric scaffolds can mitigate long-term risks associated with permanent implants currently used to treat ischemic artery disease. However, safe deployment of erodible scaffolds is predicated on understanding the interactions between evolved material by-products and local biological tissues. We developed an integrated computational model of polymeric scaffold degradation, by ...

We introduce a mathematical model of signal transmission in simple epithelial layers. The mathematical model consists of reaction-transport equations for extracellular ligands, cellular receptors, ligand-receptor complexes and a ligand releasing protease. We consider diffusion and nonstationary convective transport of protein ligands in the extracellular space. The study was carried out using ...

Schistosoma mansoni parasites affect million people worldwide. The intensity of the infection can be evaluated by the number of eggs present in the stool of an infected individual. The application of the traditional methods has been regarded as impractical in developing areas and there is a continuous search for new techniques. In face of this scenario, a new method of diagnosis was explored in ...

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. ...

Thermal ablation of malignant tumors has been conducted in patients who are not candidates for surgery for more than ten years. Recently it has been shown that low energy DC pulses can cause cell necrosis. An undesirable characteristic of DC pulses in-vivo is the stimulation of skeletal muscle. The intensity of the contraction depends in part on the duration and height of the pulse. Through the ...

In this work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include electro-osmotic flow, species transport, and electrostatics.
