The majority of elderly patients are subjected to hip bone replacement due to dislocation of bone, mechanical failure and infection. The life time of the implant varies from patient to patient depending on their daily physical activity. Once the implant fails, re-operation of hip bone replacement is performed. In United States, there are approximately 18 revision hip replacements performed for ...

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

As in all tissues, mechanical forces in the aortic valve (AV) modulate the constituent cell population’s physiology and biosynthetic activity. While advances have been made toward the understanding of this complex multi-scale relationship, the specific role that and extracellular matrix (ECM) coupling plays on the mechanical response of the AV interstitial cell (AVIC) is poorly understood. The ...

Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A computational model of a SWCNT device was developed using COMSOL Multiphysics to investigate the complete electrical ...

Inertial focusing is a promising microfluidic technique for separating and concentrating cells of interest, processes routinely utilized in many medical procedures. This phenomenon is characterized by suspended particles in a flow spontaneously migrating across streamlines to equilibrium positions within a channel cross-section. We developed CFD models in COMSOL Multiphysics® to predict the ...

Introduction: While general anesthetics control pain via consciousness regulation, local anesthetics (LAs) act by decreasing sensation in the area of administration by blocking nerve transmission to pain centers. Perioperative intra-articular administration of LAs is a commonly employed procedure in orthopedic procedures to minimize patient surgical and post-surgical pain. LAs are also co ...

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 ...
Simulation of a Magnetic Induction Method for Determining Passive Electrical Property Changes of Human Trunk Due to Vital Activities

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these changes. The method is based on the creation of a primary magnetic field that will produce eddy currents in the ...

A eletroquimioterapia é um tratamento de câncer que utiliza a combinação de agentes quimioterápicos e campos elétricos. A base teórica por trás dessa aplicação é a eletroporação. Esse fenômeno biológico consiste na abertura de poros na membrana celular devido à aplicação de pulsos elétricos. Este trabalho analisa o comportamento do campo elétrico gerado por pulsos elétricos aplicados em ...

Nerve localization is important for applications in regional anesthesia. Localization is achieved by stimulating the nerve with an electric field produced by a current from a needle inserted into the body of the patient, close to the target nerve. Modeling of the electric field in close proximity to the nerve may help to explain observed variations in threshold currents and can help to ...
