Coupled models for integrated heart simulations: a numerical study of the fluid dynamics in the left ventricle

Alfio Quarteroni, Simone Deparis, Luca Dede', Davide Forti, Antonello Gerbi

We consider the numerical simulation of integrated heart models for the study of the cardiac functioning with particular emphasis on the coupling of the muscle contraction, the fluid dynamics of the left ventricle, and the interaction with the valves. We a ...

Load Balance Control for a Humanoid Musculoskeletal Arm in Table Tennis Movement

Nadia Barbara Figueroa Fernandez

The aim of this paper is to propose a muscle control method for a humanoid musculoskeletal arm that mimics human muscle coordination from an engineering viewpoint. As muscle control is posed as a redundancy problem, the resulting muscle force corresponds t ...

Mechanical Characterization and Shape Optimization of Fascicle-Like 3D Skeletal Muscle Tissues Contracted with Electrical and Optical Stimuli

Mahmut Selman Sakar

In this study, we present a quantitative approach to construct effective 3D muscle tissues through shape optimization and load impedance matching with electrical and optical stimulation. We have constructed long, thin, fascicle-like skeletal muscle tissue ...

Triclosan Impairs Swimming Behavior and Alters Expression of Excitation-Contraction Coupling Proteins in Fathead Minnow (Pimephales promelas)

Triclosan (TCS), a high volume chemical widely used in consumer products, is a known aquatic contaminant found in fish inhabiting polluted watersheds. Mammalian studies have recently demonstrated that TCS disrupts signaling between the ryanodine receptor ( ...

Mathematical modeling and numerical simulation of excitation-contraction phenomena in the heart

In this Master thesis we aim at studying some physiological and computational aspects of the excitation-contraction mechanisms in the heart muscle. This phenomenon exhibits many complexities at different spatio-temporal scales. The relevance and applicabil ...

Optogenetic control of live skeletal muscles: Non-invasive, wireless, and precise activation of muscle tissues

Mahmut Selman Sakar

Optogenetics is an emerging new technology for controlling live cell function with light. Skeletal muscles are genetically coded to express light-sensitive proteins so that the cell's behavior may be altered by illuminating a targeted portion of the cell. ...

Triplet imaging of oxygen consumption during the contraction of a single smooth muscle cell (A7r5)

Dimitri Nestor Alice Van De Ville, Theo Lasser, Kai Johnsson, Marcel Leutenegger, Boris Hinz, Iwan Märki, Thiemo Spielmann, Aurélie Formey de Saint Louvent, Matthias Geissbühler

Triplet imaging is a novel optical technique that allows investigating oxy- gen metabolism at the single cell and the sub-cellular level. The method combines high temporal and spatial resolution, which are required for the monitoring of fast kinetics of ox ...

Formation and Optogenetic Control of 3D Engineered Skeletal Muscle Bioactuators

Mahmut Selman Sakar

Densely arrayed skeletal myotubes are activated individually and as a group using precise optical stimulation with high spatiotemporal resolution. Skeletal muscle myoblasts are genetically encoded to express a light-activated cation channel, Channelrhodops ...

Leukocyte-endothelial cell interaction is necessary for photodynamic therapy induced vascular permeabilization

Hubert van den Bergh, Elodie Debefve, Hans-Anton Lehr

Photodynamic therapy (PDT) affects vascular barrier function and thus increases vessel permeability. This phenomenon may be exploited to facilitate targeted drug delivery and may lead to a new clinical application of photodynamic therapy. Here, we investig ...

Propagation of fast and slow intercellular Ca2+ waves in primary cultured arterial smooth muscle cells

Jean-Jacques Meister, Jean-Louis Bény, Nadia Halidi

Smooth muscle contraction is regulated by changes in cytosolic Ca2+ concentration (Ca2+). In response to stimulation, Ca2+ increase in a single cell can propagate to neighbouring cells through gap junctions, as intercellular Ca2+ waves. To investigate ...
