This paper is an investigation into the effect of blood vessel movement on measurement accuracy of blood flow rate using magnetic flow meters. The investigation used a Finite Element model of the magnetic flowmeter built using COMSOL Multiphysics® software by integrating the modules of laminar fluid (blood) flow, electric and magnetic field and structural dynamics (FSI), to mimic performance of ...

Constitutive properties of living cells are able to withstand physiological environment as well as mechanical stimuli occurring within and outside the body. We examined fluid flow and Neo-Hookean deformation related to the rolling effect. A mechanical model to describe the cellular adhesion with detachment is here proposed. We developed a finite element analysis, simulating blood cells attached ...

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient’s own cells inside scaffolds. TE scaffolds are porous constructs that act as a support structure during bone regeneration and helps cells attach and ...

Diabetes mellitus affects 387 million people across the world according to the latest estimates of International Diabetes Foundation. Insulin is one of the major drugs required to keep the glucose level within desired limits in a diabetic patient. Insulin is generally administered to a patient as a subcutaneous injection and consists of two forms namely, basal and bolus. The basal dosage is ...

For medical diagnostic purposes there is an increasing need for non- (or minimal) invasive techniques to measure all kinds of parameters that can provide insight in the functioning of cells, organs or organ systems. Currently, Impedance Cardiography (ICG) is used for measurements of the heart and Electric Impedance Tomography (EIT) is used for investigating lung tissue condition. This paper ...

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 ...

Deformable image registration is a form of medical image processing that can provide insights into the development of phenomenon and variation in normal anatomical structure over time. Prior to post-operative pleural photodynamic therapy (PDT), a series of CT scans of lungs will be acquired. During PDT treatment, an infrared navigation system is used to contour the lungs and provide real-time ...

Electro-active polymer (EAP) based actuators are one of the suitable contenders for use in artificial muscles based bio-medical application because of their bio compatibility and lower active actuation voltage requirement phenomenon. At present Ionic polymer metal composites (IPMC), a type of EAP based actuator are being developed for various applications. IPMC actuator generally consist ...

Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing flow through the stenosis. To examine the interaction of these factors, we applied computational fluid ...

During cryopreservation of human embryos, ice crystal formation in the embryos or in surrounding media may cause cryodamage to them and can be lethal. A strategy to avoid this is the vitrification procedure when the embryo and the surrounding medium undergo the transition to glassy state rather than a crystalline one during cooling. Similarly, recrystallization in the embryo or the medium must ...
