Flows inside cells: From natural cytoplasmic streaming to microfluidic systems
Cytoplasmic streaming, the persistent flow of fluid inside a cell, induces intracellular transport. This plays a key role in fundamental biological processes. In this thesis, we discuss fluid flows inside cells, from naturally occurring cytoplasmic streaming to experimental techniques for inducing …

Active cellular flows: biological networks, cytoplasmic streaming and swimming bacteria
… development. This spreading is facilitated by cytoplasmic flows driven by the cortex, a contractile cytoskeletal layer at the cell boundary. Modelling the problem as boundary-driven Stokes flows in a spheroidal cell, we first present an exact spheroidal harmonics solution. Applying our results …

Whole Skin Locomotion Inspired by Amoeboid Motility Mechanisms: Mechanics of the Concentric Solid Tube Model
… effectively generating the overall motion of the cytoplasmic streaming ectoplasmic tube in amoebae. This research presents the preliminary analytical study towards the design and development of the novel WSL mechanism. In this thesis we first investigate how amoebas move, then discuss how this …

The Development of Actuators for the Whole Skin Locomotion Robot
… propels itself using a motion similar to the cytoplasmic streaming exhibited by an amoeba. In the robot there are embedded ring actuators which evert the material of the robot to produce forward motion. The robot benefits from a highly flexible exterior allowing it to squeeze into constricted …

Motion of filaments induced by molecular motors: from individual to collective dynamics
In cellular phenomena, such as cytoplasmic streaming, molecular motors translocate along microtubules carrying cargoes which entrain fluid. The piconewton forces that motors produce can be sufficient to bend or buckle the filaments. When large numbers of such forced filaments interact through the …

Effects of sublethal and lethal temperatures on plant cells
… membranes, and an irreversible stoppage of cytoplasmic streaming in leaf cells of elodea. Approximately 40 percent of the cells in elodea leaves show criteria of cell death at a temperature treatment which results in necrotic leaf tissue. Plasmolysis was observed in leaf cells at the lethal …

Study of wound healing and the involvement of the cytoskeleton in Vaucheria longicaulis variety macounii
… the wound healing process. In uncut filaments, cytoplasmic streaming is severely reduced by both Cytochalasin B and Oryzalin, with the greatest reduction observed following Cytochalasin B treatment. Work in cut filaments points to a preferential association between microfilaments and …
