We used a predefined COMSOL Multiphysics® interface to imitate biological growth and shape change (morphodynamics). We found a set of parameters that supply observed morphodynamics for an Arabidopsis embryo during its transition from globular to heart stage.

Organogenesis, the genesis of organs during embryonic development, is an active research field involving biologists, mathematicians and computational researchers. Fundamental questions of the formation of shape and the control of growth are still not answered. We focus on the development of the embryonic mouse lung and kidney. From all proposed mechanisms, a Turing Pattern-based framework as ...

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a Software. It is shown that the Fitzhugh-Nagumo equations allow for a geometrical explanation of ...

Tissue engineering (TE) is a multidisciplinary field involving principles of engineering and life sciences to improve the health and quality of life by repairing, restoring, maintaining, or enhancing tissue and organ function using cells, scaffolds, and growth factors alone or in combination. There are several artificial tissues that are already being used which include fabricated skin, ...

Cells are complex entities which not only passively sense external stimuli (viz. chemical, optical or mechanical) but also interact with extracellular matrix (ECM) by regulating cellular behavior such as growth, proliferation, migration, etc. Monitoring cell growth and migration of adherent cells becomes a crucial factor in determining cell-cell and cell-substrate interaction, important for ...

Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological examination with MRI/CT scans which is costly and time consuming. Microwave Tomography (MWT) is proposed as a ...

In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, tissue conductivities, and waveform since it uses electrode amplitude. We replicated a leading calibrated nerve ...

Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions and estimates, posing difficulties in correlating experimental observations with theories. Among the commonly ...

Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of cellular acceptors with 1O2. A mathematical model has been previously developed to incorporate the macroscopic ...

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of the self-contained microfluidic-based electrochemical cell portion of a multifaceted analysis system is ...
