Abstract:
This work describes, in an accessible manner, the structures and functions of biomolecular motors. These motors are complex supra macromolecular structures which convert directly chemical energy into mechanical one and vice versa, accomplishing important cellular functions: chromosome migration during mitosis phase of cell cycles, DNA semiconservative duplication, vesicle transportation along filaments and tubules, etc. They can be classified as linear (e.g., actomyosin complex into sarcomeres, DNA helicase and DNA polymerase) and rotary motors (e.g., ATP synthase, prokaryotic flagella), eukar

Abstract:
Innate immunity forms the core of the human body's defense system against infection, injury, and foreign objects. It aims to maintain homeostasis by promoting inflammation and then initiating tissue repair, but it can also lead to disease when dysregulated. Although innate immune cells respond to their physical microenvironment and carry out intrinsically mechanical actions such as migration and phagocytosis, we still do not have a complete biophysical description of innate immunity. Here, we review how engineering tools can be used to study innate immune cell biophysics. We first provide an o

Abstract:
Cellular metabolism implies a permanent transport through membranes of a great diversity of particles (e.g., ions, molecules, macromolecules, protein vesicles, etc.) in and out of the cells. The transport phenomena can be classified as passive (down the concentration gradients, driven solely by thermal agitation) or active (against the concentration gradients, driven by an energy supply) and selective (i.e., through specific pathways) or nonselective through membrane lipid bilayers.

With a scope that spans the hierarchy of biological organization from molecules and cells to organisms and populations, the discipline of biophysics has been proven to be particularly well suited for connecting the molecular embodiments of human diseases to the medical conditions experienced by patients. Recently, fundamental biophysical research on aberrant proteins involved in maintaining salt and water balance in our lungs, oxygen transport from our lungs to the rest of the body, and the pumping of blood by our hearts have been successfully translated to the creation of transformational new

Abstract:
This thesis presents five, separate but interlinked, studies of computer models of cells in the mammalian auditory system. The first study presents a comparative evaluation of eight computer models of inner hair cell function. The models simulate the release of a chemical transmitter substance from the base of a hair cell in response to sound stimulation. The simulations take the form of differential equations which are evaluated 20,000 times per second of simulated events. The models were evaluated in terms of their agreement with physiological data and their computational efficiency.

This work comprises analyses of cell fate decision-making in response to DNA damage. DNA damage is a ubiquitous threat to genomic stability, and depending on the type and extent of the damage, can lead to widespread changes in cell function as well as cell death. How apoptosis, or programmed cell death, is triggered in damaged cells was studied in different cell types for different types of damage.

Abstract:
A theoretical and experimental method is described whereby the hydrodynamic forces, both normal and shear, acting on the spheres of a doublet can be calculated. This is applied to a system of sphered human red blood cells agglutinated by human hyperimmune anti-B antiserum undergoing Poiseuille flow and observed using the traveling microtube technique. The mean forces separating the cells of individual doublets were found to be proportional to antiserum concentration from 0.73 to 3.56% v/v, normal forces increasing from 0.060 to 0.197 nN and shear forces from 0.023 to 0.072 nN.

Abstract:
Mechanical loading is crucial in modulating the physiology and architecture of bone. Previous experiments indicated intercellular communication among osteoblasts upon mechanical stimulation, suggesting the involvement of a soluble signal mediator. Extracellular adenosine triphosphate (ATP) functions as signaling molecules in many cell regulation processes, therefore appears to be a prone candidate. ATP acts on osteoblasts through multiple P2 receptors. To provide insights on the roles of individual receptors, we modeled ATP concentration dependence for different P2 receptors. Next, the pro
