    "This book is based upon cutting-edge research conducted in the authors lab (Cellular Bioengineering), which over the past decade has developed a number of sophisticated techniques to facilitate use of 3D cell based assays or biosensors. This book uses data from peer-reviewed publications to conclusively justify use of 3D cell cultures in cell-based biosensors (assays) for (HTS). The majority of assays performed in accelerated drug discovery processes are biochemical in nature, but there is a growing demand for live cell-based assays. Unlike biochemical ones, cellular assays are functional approximations of in vivo biological conditions and can provide more biologically relevant information"--Provided by publisher.

    In this work we present a series of scientific contributions made to the study of the impact of projectiles into tissue-like materials, specifically the synthetic artificial tissue simulant Perma-Gel. These contributions consist of a combination of experimental observations, algorithmic ideas and numerical tools which demonstrate a series of problems and solutions to trying to simulate nearly incompressible soft tissues using finite elements. A number of experiments were performed by taking high-speed footage of the firing of spherical steel bullets at different speeds into Perma-Gel, a new thermoplastic material used as a proxy to human muscle tissue. This work appears to be the first publicly released experimental work using Perma-Gel and is part of the small amount of non-classified work looking at ballistic gelatin behavior. A number of experimental observations were made regarding the material behavior, elastic and plastic deformation around the projectile, and the possibility of cavitation. This work introduces an explicit dynamic contact algorithm that takes advantage of the asynchronous time stepping nature of Asynchronous Variational Integrators (AVI) to improve performance when simulating elastic-body rigid-wall contact. We demonstrate a number of desirable properties over traditional one-time-step methods for the simulation of solid dynamics and provide a number of examples highlighting the advantages of this method. The explicit contact algorithm and AVI was used to simulate the impact of a projectile into a simulated block of gelatin, but was hindered by difficulties using the realistic material parameters. Using a parallelized version of the algorithm, large-scale simulations were performed for progressively smaller shear moduli. As the simulations approached realistic values for the shear modulus, unstable element configurations formed which required infeasibly small time steps to successfully resolve. The behavior observed for the shear moduli we could numerically simulate with did not resemble the experimental results. To simulate with smaller values, we had to go to an axisymmetric setting. The axisymmetric setting increased the range of shear moduli which could be simulated and demonstrated the same dynamic behavior, though the issue of unstable element configurations continued to occur in extreme cases. To deal with the issue of unstable elements, we created an axisymmetric remeshing strategy to compensate for the unstable element configurations and insufficient spatial resolution. This strategy consists of periodically applying a remeshing and transfer algorithm that updates highly deformed finite element meshes with configurations formed with elements having uniform aspect ratios and local refinement in important areas. The axisymmetric setting with remeshing increased the range of potential shear modulus values that could be simulated. This allowed for the identification of qualitative similarities in the transient behavior between the numerical results and the experimental footage.

    The presence of oriented features in images often conveys important information about the scene or the objects contained; the analysis of oriented patterns is an important task in the general framework of image understanding. As in many other applications of computer vision, the general framework for the understanding of oriented features in images can be divided into low- and high-level analysis. In the context of the study of oriented features, low-level analysis includes the detection of oriented features in images; a measure of the local magnitude and orientation of oriented features over the entire region of analysis in the image is called the orientation field. High-level analysis relates to the discovery of patterns in the orientation field, usually by associating the structure perceived in the orientation field with a geometrical model. This book presents an analysis of several important methods for the detection of oriented features in images, and a discussion of the phase portrait method for high-level analysis of orientation fields. In order to illustrate the concepts developed throughout the book, an application is presented of the phase portrait method to computer-aided detection of architectural distortion in mammograms.

    Of the two pathways through which we hear, air conduction (AC) and bone conduction (BC), the fundamental mechanisms of the BC pathway remains to be poorly understood, despite its clinical significance. In the first study, a finite-element (FE) model of a human middle ear and cochlea was developed to gain insight into the mechanisms of BC hearing. BC excitations were simulated in the form of rigid-body vibrations of the surrounding bony structures in the x, y, and z orthogonal directions. The results show that the BM vibration characteristics are essentially invariant regardless of whether the excitation is BC, independent of excitation directions, or for AC. Analysis reveals that this is because the BM vibration apparently responds only to the anti-symmetric slow wave cochlea fluid pressure component and not the symmetric fast wave pressure component. In the second study, an improved three-dimensional FE model of a human middle ear coupled to a cochlea was formulated. The geometry of both the middle ear and cochlea, including semicircular canals, was obtained from micro-computed tomography ([mu]CT) images. In the study, BC and AC excitations were simulated as the same way as the previous simulation in the first study. After testing a range of vibrational directions, it was found that the vibrational direction normal to the BM surface at the base of the cochlea caused the highest BM velocity response across all tested frequencies--higher even than an excitation direction normal to the BM surface at the (non-basal) best-frequency locations corresponding to the other stimulus frequencies. The basal part of the human cochlea features a well-developed hook region, in which the BM undergoes a sudden curvature that produces the largest difference in fluid volume between the scala vestibuli (SV) and scala tympani (ST) found throughout the whole cochlea, and due to the sudden curvature of the hook region, the normal direction to the BM surface in this region differs significantly from the normal directions to the BM along the rest of the length of the cochlea. In the third study, the effects of otosclerosis and superior semicircular canal (SSC) dehiscence (SSCD) on hearing sensitivity were investigated via AC and BC pathways, using the FE model developed in the second study. Otosclerosis conditions were simulated by stiffing stapes annular ligament and removing the middle-ear inertia through removing stapedius tendon and incudostapedial joint. Dehiscences were modeled by removing a section of the outer bony wall of the SSC and applying a zero-pressure condition to the fluid surface thus exposed. In the results, otosclerosis condition caused the biggest bone-conduction hearing loss around 1.5 kHz, which is called 'Carhart notch'. In addition, dehiscence caused decreasing of the basilar membrane velocity, VBM(x), and fluid pressure in the cochlea in air conduction whereas increasing in bone conduction at low frequencies. Furthermore, the location and size of dehiscence affected the BC hearing threshold. Not previously shown is that the initial width (defined as the edge of dehiscence at which the flowing energy from the oval window meets for the first time) on the vestibular side of the dehiscence has more effect than the area of the dehiscence. The analyses of the FE model further predict that the ABG due to a dehiscence should converge to 0 dB at 10 kHz.

    Unlike normal tissues, solid tumors have a metabolic phenotype that favors energy-inefficient glycolysis rather than more efficient, but oxygen consuming, oxidative phosphorylation, even when oxygen levels are adequate. This metabolic shift towards glycolysis, discovered by Warburg in 1924, has been studied for more than 80 years, but the mechanism of the phenomena is still unclear due to lack of tools for in vivo investigation. Dynamic nuclear polarization in combination with the recent development of a dissolution process that retains the increased polarization into the liquid state opened new possibilities for the real-time investigation of in vivo metabolism using C13 magnetic resonance spectroscopy. In particular, hyperpolarized [1-13C]pyruvate, a substrate occupying a key nodal point in the glucose metabolic pathway, has been successfully demonstrated as a neoplasm biomarker via elevated lactate labeling in tumors. However, additional downstream products of pyruvate metabolism, such as that occur in mitochondria of brain tumor, have been veiled due to low signal-to-noise ratios. The first part of the thesis is on the quantitative assessment of mitochondrial function in normal rat brain and glioma by detecting 13C-bicarbonate following the bolus injection of [1-13C]pyruvate. The feasibility of quantitatively detecting 13C-bicarbonate in tumor-bearing rat brain is demonstrated for the first time. The optimized protocol for chemical shift imaging and high concentration of hyperpolarized [1-13C]pyruvate were used to improve measurements of lactate and bicarbonate in C6 glioma-transplanted rat brains. Moreover, the immediate response to dichloroacetate treatment, which upregulates pyruvate flux to acetyl-CoA, is also presented. It is demonstrated that the simultaneous detection of lactate and bicarbonate provides a tool for a more comprehensive analysis of glioma metabolism and the assessment of metabolic agents as anti-cancer drugs. In the second part of the thesis, further investigation on mitochondrial metabolism, including tricarboxylic acid cycle, is presented by acquiring single-time point chemical shift imaging data from rat brain in vivo after administration of highly concentrated [2-13C]pyruvate. A C13 surface coil optimized for rat brain was built to increase sensitivity of signal detection. [5-13C]glutamate, [1-13C]acetyl carnitine, and [1-13C]citrate were detected besides [2-13C]pyruvate and [2-13C]lactate, for the first time in brain. Change of the tricarboxylic acid cycle activity in brain was also investigated by infusing dichloroacetate. The increase of [5-13C]glutamate was detected primarily from brain, whereas [1-13C]acetyl carnitine was increased in peripheral tissues after the infusion of dichloroacetate. The third part focuses on dynamic measurements of hyperpolarized substrates to obtain exchange rates in addition to concentrations, and proposes the apparent conversion rate as a new metric to detect glioma by comparing the conversion rates in glioma, normal appearing brain, and basilar vasculature in female Sprague-Dawley rats with C6 glioma cells implanted. Whereas single-time point measurements give a snapshot image of tissue metabolism, the estimated apparent rate constant yielded a better differentiation between the tissue types than the lactate-to-pyruvate ratio, which has been the most common metric used to date. This study demonstrates the feasibility of quantitatively detecting C13-labeled bicarbonate and glutamate in vivo, permitting the assessment of dichloroacetate-modulate changes in pyruvate dehydrogenase flux in both normal rat brain and glioma. The simultaneous detection of both lactate dehydrogenase and pyruvate dehydrogenase activities will likely improve our ability to both assess and monitor metabolic therapies of brain and other cancers by providing non-invasive in vivo measures of glycolysis and oxidative phosphorylation.

    Recent successes in the pharmaceutical industry have yielded a variety of new drugs based on proteins and nucleic acids. While these drugs are very promising, they are only effective once they are inside cells. Unfortunately, transporting drugs into cells tends to be challenging because cell membranes provide a protective barrier. However, there is hope for these drugs since researchers have identified many drug delivery agents that can shuttle drugs past this barrier. Cell penetrating peptides (CPPs) are particularly promising delivery agents due to their low toxicity and ability to deliver a wide number of therapeutic agents. However there are challenges to using CPPs, because their delivery mechanisms cannot yet be controlled. Engineering new CPPs that use specific, known translocation mechanisms would be a key achievement that could increase delivery efficiency and prevent unwanted side effects. Accomplishing this goal requires new experimental methods for determining the factors that control a CPP's translocation mechanisms. In this thesis I present new atomic force microscopy (AFM) methods for studying CPPs and other cell membrane active species. I first present a theoretical model that shows how results from AFM can indicate whether CPPs change the energy barrier to bilayer penetration. I then describe new experimental AFM methods we developed for examining CPP transduction mechanisms.

    The fruit fly, Drosophila melanogaster, is a key model species for biological research. Trained humans can manipulate, inspect and dissect individual flies, but these operations are often rate-limiting bottlenecks for screening and experimentation. Here I present a high-speed, economical robot for handling non-anesthetized adult flies. Using machine vision the robot tracks a fly's thorax and gently grabs it ~400 ms after targeting. The robot can then translate and rotate the picked fly, inspect its phenotype, dissect or release it, and thereby rapidly prepare multiple flies sequentially for a wide range of experimental formats. In one illustration, the robot restrained flies and dissected the cuticle to permit two-photon imaging of neural dynamics. In another, the robot sorted flies by sex. The robot's tireless capacity for accurate, repeatable manipulations will enable experiments and biotechnology applications that would otherwise be totally infeasible, especially those requiring high-throughput capture, testing and assessment of individual fly attributes.

    The priorities of a climbing legged robot are to maintain a grasp on its climbing surface and to climb efficiently against the force of gravity. Climbing robots are especially susceptible to thermal overload during normal operation, due to the need to oppose gravity and to frequently apply internal forces for clinging. These priorities guided us to develop optimal climbing behaviors under thermal constraints. These behaviors in turn profoundly constrain the choice of gait regulation methods. We propose a novel algorithm: "travel-based" gait regulation that varies foot detachment timing, effectively modifying stride length and frequency in order to maintain gait phasing, subject to kinematic and stability constraints. A core feature of the algorithm is "travel, " a new metric that plays a similar role to relative phasing. The method results in linear equations in terms of travel, leading to straightforward tests for local and global convergence when, for example, disturbances such as foot slippage cause departures from the nominal phasing. We form recurrence maps and use eigenvalue and singular value decomposition to examine local convergence of gaits. To examine global convergence, we implemented a computational geometry technique in high-order spaces. Our travel-based algorithm benefits from a compact code size and ease of implementation. We implemented the algorithm on the RiSE and Stickybot III robots as well as a virtual hexapod in a physics simulator. We demonstrated quickly converging gaits on all platforms as well as gait transitions on Stickybot III and the virtual hexapod.

    Cardiovascular disease affects more than 70 million Americans and is the number one cause of mortality in the United States. Because the regenerative capacity of cardiac tissue is limited, human pluripotent stem cells (hPSC) have emerged as a potential source for cellular-based therapies. However, for these therapies to be effective, sufficient amounts of differentiated cells must be produced, these cells must be identified and sorted, and, upon implantation, arrhythmias must be avoided. In this dissertation, I describe the biochemical control of hPSC for their directed differentiation into cardiomyocytes, electrical control for electrophysiology-based cell sorting, and optogenetic control for temporal synchronization. For future therapy, the in vivo application of optical stimulation could allow immediate, precise, and specific synchronization of efficiently derived and purified hPSC-CM with patient cardiac rates and rhythms. This, in turn, would significantly reduce the chance of arrhythmias arising from implanted hPSC-CM, and, therefore, contribute towards establishing a safe and effective cell-based therapy.

    While coronary heart diseases are considered the most deadly medical conditions in terms of overall deaths per year, orthopedic maladies are the costliest. One of the most prevalent orthopedic conditions is low back pain, which stems from degenerative tissue changes within the spinal column and associated spinal cord and peripheral nerve injuries. Treatment successes in conservative and surgical treatment are mixed, although the rates of spine surgery have dramatically increased over the past decade. Surgical treatment is considered a last resort, and of all the surgical approaches, spinal fusion is the most common for the treatment of low back pain. Since spinal fusion has been in use in the clinic for several decades now, results of long-term retrospective clinical reviews are now becoming available. Some of these studies have shown that spinal fusion may induce secondary injuries such as adjacent tissue regeneration, which may require additional surgical treatment. To overcome some of these complications, posterior dynamic stabilization has been introduced as an alternative to fusion surgery. Posterior dynamic stabilization is still considered mostly experimental and the majority of spine companies with ambitions in this field have not yet settled on particular design goals and implant concepts. A significant hurdle for entry to the market for such devices is the lack of understanding of what the ideal function of the device is, and how the implants should interact with the spinal column. The objective of this thesis was to evaluate the functionality of posterior dynamic stabilization depending on patient conditions such as mobility and body mass and to suggest efficient rigidities of the dynamic device when considering patients' characteristics. This study is divided into three specific aims. The purpose of the first aim was to investigate the significant influence of a patient's spinal kinematics on dynamic stabilization. The patients were divided by segmental range of motion (L3-L4) into two groups (hyper-mobility and hypo-mobility) and finite element (FE) models were generated for these respective groups. This study showed that patient characteristics such as mobility produced different spinal kinematics after dynamic stabilization and demonstrated that the effectiveness of dynamic stabilization was increased when the mechanical properties of the device were changed in response to patient characteristics. The purpose of the second aim was to evaluate the stabilization devices in relation to patients' body mass and spinal mobility, testing the effects of dynamic stabilization devices of varying levels of rigidity. Based on analyzed results of the spinal mobility at the diseased level (L4-L5), the hyper-mobility patients were divided into three groups, based on severity. Depending on the body mass in the hyper-mobility patients, the patients were divided into three groups. The findings of the study demonstrated the significant influence of patients' body mass and mobility on spinal kinematics after dynamic stabilization. The purpose of the third aim was to investigate the effect of implant rigidity on spinal kinematics utilizing a cadaveric tissue model. This in-vitro study was designed to validate the biomechanical influence of physiological loading after dynamic stabilization. The results of this in-vitro study showed that patients' characteristics change spinal segmental motion and different implant rigidities of the dynamic stabilization device also produce varying spinal kinematics depending on patients' conditions. Through these in-vitro tests, this thesis readdresses the importance of considering patient characteristics in the design of appropriate devices for spinal stabilization, and to select the right implants for the right patient population.

    This dissertation investigated the role of biomechanics in two physiological systems, the heart and bone. Biomechanics motivates the study and characterization of how cells sense external forces and convert these signals into an intracellular response in a process called mechanotransduction. Three independent studies were designed with the goal of applying mechanical forces that mimic the in vivo microenvironment of either the heart or bone. The aim of these studies was to better under the mechanisms driving cellular processes, including cardiac myocyte differentiation and osteoblast mechanotransduction. The first study presents the design and implementation of tissue engineering approach to stem cell-based myocardial therapy. Three dimensional engineered heart tissue was formed by suspending human embryonic stem cell-derived cardiac myocytes isolated from beating embryoid bodies in a soluble extracellular matrix, and an in vitro mechanical conditioning regimen was applied at physiological levels of myocardial strain. The viability of the engineered stem cell tissue was monitored in vitro and in vivo for up to 8 weeks using molecular imaging of reporter gene activity. The application of cyclic mechanical strain in vitro resulted in cellular alignment along the axis of strain and an elongated cellular morphology with a high nuclear to cytoplasmic ratio, typical of neonatal cardiac myocytes, as well as increased expression of cardiac troponin I, in comparison to static controls. Analysis of the in vitro and in vivo bioluminescence imaging data demonstrated the viability of engineered heart tissue constructs; however, histology results showed immature cells within the implanted constructs, suggesting an inability of the stem cell-derived cardiac precursors to maintain a cardiac phenotype in vivo, as well the inherent inefficiency of the beating embryoid body method to identify and isolate cardiac myocyte precursors. The functional shortcomings exhibited by the embryoid body-based differentiation of embryonic stem cell-derived cardiac myocytes in the first study motivated further refinement of cardiac myocyte differentiation techniques. Therefore, the second study executed the design and fabrication of a microelectromechanical platform to study the role of electrical and mechanical stimulation in cardiac myocyte differentiation. The fabrication process used a combination of soft lithography and traditional microfabrication techniques to pattern thin film metal electrodes on an elastomeric polymer membrane. The completed device enabled coupled characterization and imaging of cardiac myocytes precursors, and the ability to assess the range of mechanical forces, up to 10% equibiaxial strain, that may induce or maintain a cardiac fate. Electrical continuity was demonstrated under static conditions but not under strain, and improvements in metal deposition and adhesion could address this performance defect. Beating clusters containing human embryonic stem cell-derived cardiac myocytes were plated on fabricated membranes, uncoated and coated with Matrigel, and cell viability was monitored using contrast microscopy. The third study transitioned to a different mechanical model of physiological forces, which was the application of oscillatory fluid flow-mediated fluid shear stress generated by the loading and unloading of bone. Specifically, the role of focal adhesion kinase, a protein tyrosine kinase recruited at focal adhesions and a major mediator of integrin signaling pathways, was studied in osteoblast mechanotransduction. The biochemical and transcriptional response of focal adhesion kinase mutant osteoblasts to physiological levels of shear stress induced by oscillatory fluid flow was impaired as measured by prostaglandin E2 release and cyclooxygenase-2 gene expression. Restoration of focal adhesion kinase expression with site-specific mutations at two tyrosine phosphorylation sites demonstrated that phosphorylation events play a role in prostaglandin release following oscillatory fluid flow. In conclusion, the role of mechanical forces, including the effect of cyclic mechanical strain in human embryonic stem cell-derived cardiac myocyte tissue engineering and the fluid shear stress-induced response of focal adhesion kinase mutant osteoblasts, was successfully demonstrated and quantified in this dissertation.

    The outermost layer of human skin, the stratum corneum (SC), is subject daily to variable ambient moisture and temperature conditions as well as application of potentially damaging cleansing agents. The inevitable results of these exposures are "tightness" of the skin which is directly related to the buildup of tensile residual drying stresses in the SC layer. In this work, we first describe the application of the substrate curvature technique to quantitatively measure the magnitude of these stresses and their relationship to selected drying environments and times. The SC drying stresses were observed to be very sensitive to the relative humidity and temperature of the drying environment as well as harshness of the chemical treatment. There was a strong correlation with the SC drying stresses and the chemical potential of water in the drying environment. The evolution of drying stresses in SC is discussed in relation to the effects of hydration and damage caused by chemical treatments on the underlying SC structure. We also describe the application of the substrate curvature technique to characterize stresses in occlusive topical coatings. We then extend the substrate curvature technique to measure the combined effects of the coating applied to human stratum corneum (SC) where the overall drying stresses may have contributions from the coating, the SC and the interaction of the coating with the SC. We show how these separate contributions in the coating and SC layers can be differentiated. Using this methodology, we characterize the effect of a range of moisturizing treatments on the drying stresses in human stratum corneum. Following moisturizer treatment, the SC was observed to have distinctive stress profiles with drying time depending on the effectiveness of the treatment. The stress values of specimens treated with the humectant moisturizers were observed to increase and stabilize after a few hours in the drying environment where they remained relatively constant until the end of exposure to the drying environment whereas the stress values of specimens treated with the emollient treatments were observed to rise rapidly to a peak stress value and relax to a final stress value. The effect of moisturizing treatments on the SC drying stresses was rationalized in terms of SC water loss and the chemical state of the SC components. Finally, we employ a fracture mechanics approach to understand the implications of the drying stresses in SC as a mechanical driving force for damage propagation (e.g. cracking and chapping) in the tissue. The crack driving force G was found for several cracking configurations and compared with the intercellular delamination energy, Gc, which is a property of the tissue that provides a measure of the resistance to cracking. Using this approach, we demonstrate how damaging treatments enhance and moisturizing treatments alleviate the propensity for dry skin damage.

    Biomedical Signals and Systems is meant to accompany a one-semester undergraduate signals and systems course. It may also serve as a quick-start for graduate students or faculty interested in how signals and systems techniques can be applied to living systems. The biological nature of the examples allows for systems thinking to be applied to electrical, mechanical, fluid, chemical, thermal and even optical systems. Each chapter focuses on a topic from classic signals and systems theory: System block diagrams, mathematical models, transforms, stability, feedback, system response, control, time and frequency analysis and filters. Embedded within each chapter are examples from the biological world, ranging from medical devices to cell and molecular biology. While the focus of the book is on the theory of analog signals and systems, many chapters also introduce the corresponding topics in the digital realm. Although some derivations appear, the focus is on the concepts and how to apply them. Throughout the text, systems vocabulary is introduced which will allow the reader to read more advanced literature and communicate with scientist and engineers. Homework and Matlab simulation exercises are presented at the end of each chapter and challenge readers to not only perform calculations and simulations but also to recognize the real-world signals and systems around them.

    Evaluating biomedical technology poses a significant challenge in light of the complexity and rate of introduction in today's healthcare delivery system. Successful evaluation requires an integration of clinical medicine, science, finance, and market analysis. Little guidance, however, exists for those who must conduct comprehensive technology evaluations. The 3Q Method meets these present day needs. The 3Q Method is organized around 3 key questions dealing with 1) clinical and scientific basis, 2) financial fit and 3) strategic and expertise fit. Both healthcare providers (e.g., hospitals) and medical industry providers can use the Method to evaluate medical devices, information systems and work processes from their own perspectives. The book describes the 3Q Method in detail and provides additional suggestions for optimal presentation and report preparation.

    Nature has been evolving unparalleled molecular designs with extraordinary activity, simplicity, efficiency, and durability. The process of biomimicry takes inspiration from Nature. In this dissertation, I focused on the development of functional analogues of natural peptides and protein polymers for several applications that continue to challenge the biomedical field. Five applications were discussed: The first three sections focus on bioactive peptides that are generally shorter than 50 amino acids. The goal was to preserve the bioactivity of the natural peptides while reducing their natural sensitivity to proteases and fast in vivo clearance. The last two sections focus on developing protein polymer-based hydrogels. The goal was to generate biomimicking scaffolds for tissue regenerations. (i) Poly-N-substituted glycines, or peptoids, provide a biostable scaffold that can display a great diversity of side chains in highly tunable sequences via facile solid-phase synthesis. Current chemotherapeutics in oncology are often limited by side effect profiles and selection for drug resistance. Herein, I present a library of anticancer peptoids that mimic the cationic, amphipathic structural features of host defense peptides and explore their structure-activity relationship, and killing mechanisms. Several peptoids were found with broad cytotoxicity against cancer cells as well as the ability to overcome multidrug resistance. An initial in vivo study with a primary, orthotopic human breast cancer xenotransplantation model demonstrated anticancer efficacy of one of the studied peptoids. (ii) Cell-penetrating peptides have found numerous applications in biology and medicine as molecular transporters. We developed a library of cationic, amphipathic peptoids as a novel class of transporters and investigated the relationships between their structures, cellular uptake efficiency, and the associated cytotoxicity. Both guanidinium heads and bulky, aromatic hydrophobic residues were found to render the cationic, amphipathic constructs more permeable. Moreover, different internalization mechanisms were observed for peptoid transporters with distinct structures. One peptoid was identified as a promising transporter with excellent cellular uptake efficiency and low cytotoxicity. (iii) Bombesin (BBN) peptide can bind with high affinity and specificity to the GRP receptors (GRPR) which are upregulated invasive prostate cancer. BBN(7-14) provides a promising basis for developing radiometallated diagnostic or therapeutic radiopharmaceuticals to target GRPR positive prostate cancer. I report a design of a 4-arm PEG-based platform with multivalent BBN(7-14) for targeted delivery to the GRPR positive prostate cancer. The PEG-BBN conjugates displayed comparable tumor uptake as the free BBN while having both a lower liver uptake and higher tumor-to-blood ratio in a biodistribution study. (iv) Regenerative medicine is in need of bioactive extracellular matrix-like scaffolds that can interact with cells and allow tissue regeneration in a well-controlled manner. Via "controlled cloning", matrix metalloproteases (MMP) degradation sites were built into multiple sites along a protein polymer that can be enzymatically crosslinked into a previously established non-bioactive hydrogel systems. The incorporation of MMP degradation sites greatly improved cell infiltration into the hydrogel. (v) Lastly, a novel in situ forming hybrid, biomimetic hydrogel comprising bioactive recombinant protein polymers, hyaluronic acid (HA) and polyethylene glycol (PEG) was developed. In a preliminary study, this hydrogel was found to be biocompatible and bioactive, which opens up future studies with this hydrogel system.

    The work presented herein is concerned with the development of biophysical methodology designed to address pertinent questions regarding the behavior and structure of select pathogenic agents. Two distinct studies are documented: a shock tube analysis of endospore-laden bio-aerosols and a correlated AFM/NanoSIMS study of the structure of vaccinia virus. An experimental method was formulated to analyze the biological and morphological response of endospores to gas dynamic shock waves. A novel laser diagnostic system was implemented to provide time resolved data concerning the structural decomposition of endospores in shock-heated flows. In addition, an ex situ methodology combining viability analysis, flow cytometry and scanning electron microscopy was employed to both assess the biological response of the endospore to the shock event, as well as to provide complementary data regarding the structural state of the treated endospore. This methodology was implemented to model the shock wave induced response of a variety of Bacillus endospores. The results are subsequently synthesized into a theoretical framework to be employed in modeling the interaction of endospore-laden bio-aerosols with blast waves. An analytical method combining atomic force microscopy (AFM) and nanometer-scale secondary ion mass spectrometry (NanoSIMS) was developed to examine the spatial localization and depth distribution of specific biological elements in viral systems. This methodology was implemented to analyze the distribution of 13C labeled fatty acids as well as 15N labeled thymidine in individual nanometer sized vaccinia viral particles. Based upon the 13C and 15N signals, three-dimensional depth-resolved data regarding the architecture and localization of the virion lipid membrane and the nucleoprotein complex was generated. In addition, this methodology was employed to provide direct correlation of architectural and chemical data for isolated sub-viral structures. The technique and results presented herein represent a novel tool for the structural and chemical study of both intact viral particles as well as specifically targeted sub-viral elements.

    Polyketide synthases (PKSs) are multi-functional enzymes, which synthesize natural products known as polyketides. These complex molecules have a diverse range of medicinal properties. Biosynthetic engineering of the multi-modular PKSs is attractive due to their modularity and colinearity, which, if understood at the molecular level, could allow for the efficient and predictable regioselective chemical manipulation of polyketides. A minimum combination of a [beta]-ketosynthase (KS), an acyltransferase (AT), and an acyl carrier protein (ACP) is required for the assembly of acyl-CoA precursors into complex polyketide products. This work will focus on AT domains, which are the primary gatekeepers for stepwise incorporation of acyl-CoA building blocks into a growing polyketide chain. In our initial investigations, protein interactions between AT, ACP and flanking AT linkers from a prototypical multimodular 6-deoxyerythronolide B synthase (DEBS) were systematically explored, guided by recent high-resolution structures. Our results indicate that N/C terminal linkers of the modular DEBS AT domain contributed to both efficiency and specificity of transacylation. Representative DEBS AT3 and AT6 domains were also observed to have greater than 10-fold AT specificities for their cognate ACP substrates as compared to other ACPs in the DEBS PKS. In comparison, there is only modest discrimination for its native ACP by the standalone AT from the "AT-less" disorazole synthase (DSZS). These "AT-less" multimodular PKS lack AT domains in their modular assembly, and instead, transacylation is supplied by a trans-acting discrete AT. With its higher transacylation activity for DEBS ACPs compared to their natural ATs (> 40-fold), DSZS AT presents new opportunities for regioselective modification of a polyketide backbone and thus prompting further structural and biochemical investigations. Towards the analysis of DSZS AT, we report crystal structures of trans-acting AT resolved at 1.51 Å, and that of its acetate complex at 1.35 Å resolution. Comprehensive alanine-scanning mutagenesis of its native ACP1 substrate also identified a conserved Asp45 residue on the ACP for AT interactions. This conserved residue is proposed to contribute to the observed AT promiscuity. Supplementing in silico protein docking with these results, a model for DSZS AT and ACP interactions was derived. Working towards high-resolution structural characterization of this interface, we developed a novel strategy for covalently cross-linking and purifying a catalytically relevant DSZS AT-ACP complex. Finally, trans complementation of methylmalonyl CoA specific DEBS modules was also accomplished in vitro with DSZS AT for malonyl CoA incorporation. From our investigations, we have gained new insights into the protein-protein interactions that play a major role in the efficient biosynthesis of structurally complex polyketides. These results also reveal important considerations and opportunities for biosynthetic engineering within the multi-functional assembly lines.

    Our bones are complex and beautiful structures that highlight that Nature is a masterful materials scientist. These composite structures of minerals, proteins, and cells are capable of maintaining a remarkable, ever-changing balance based on an individual's biomechanical needs. Growing, running, jumping, sitting, sleeping -- all of our actions and inactions are chronicled and inform the processes of new bone formation and old bone resorption. The hierarchical microstructure, building from calcium phosphate nanocrystals embedded in collagen fibers, underscores the importance of mineral and organic components that synergistically contribute to the toughness of bone needed daily. Unfortunately, due to trauma or disease, at times our bones fail and are unable to heal themselves. It is for these instances that the field of Regenerative Medicine works to develop therapies built on expertise from materials science, engineering, and medical fields. Using protein engineering and bone biology as the starting foundation, my thesis work has focused on the development of two protein-engineered biomaterials for the improvement of regenerative medicine therapies focused on osseointegration of implants and bone regeneration. Engineered protein biomaterials harness the extensive toolkit provided to us by Nature, which includes the machinery to synthesize protein materials and myriad functional pieces to mix and match in our novel designs. With these tools I've helped develop an engineered elastin-like protein to be a photocrosslinkable, cell-adhesive, thin-film coating to improve the osseointegration of implants used to stabilize fractures. The material demonstrates increased speed and extent of cell attachment to coated surfaces, serving as proof of principle for use of this material in stimulating integration of coated implants through improved implant-cell interactions. Focusing my attention on non-healing skeletal defects, I worked with MITCH, our Mixing-Induced, Two-Component Hydrogel, to develop it for stem cell delivery and bone regeneration applications. MITCH employs molecular recognition of a peptide domain binding pair for gentle, on-demand, 3D cell encapsulation at constant physiological conditions. Further using this binding strategy to emulate the intimate interface between organic and mineral phases in native bone by crosslinking mineral nanoparticles into the hydrogel network via specific molecular interactions, I created a material capable of delivering adipose-derived stem cells and stimulating fast bone regeneration in critical-size calvarial defects. Regenerative medicine brings together the renewing power of stem cells and the rational design of biomimetic niches to help the body heal when it is incapable of doing so without assistance. Taken together, this body of work validates the strategy of designing protein-engineered biomaterials by taking cues from Nature to further the development of regenerative medicine therapies, improving their success and widespread adoption.

    Cardiac C-arm CT is a valuable imaging modality that can provide three-dimensional images of the heart during an interventional procedure. As the technology advances to provide better image quality and faster acquisition times, the potential clinical uses increase. Visualization of myocardial defects could directly impact the guidance, procedure time, and outcome of various interventional procedures. In this work, I developed protocols to optimize low-contrast detectability for cardiac C-arm CT and performed in vivo studies to validate using C-arm CT for imaging myocardial necrosis during a cardiac interventional procedure. Initial in vivo investigations were used to evaluate the contrast injection protocol for ideal timing, dilution, catheter type, and injection location. Additionally, x-ray parameters including filtration, kVp, dose, and collimation were optimized for low-contrast detectability and minimization of artifacts. A 4 sweep x 5 s, ECG-gated imaging protocol using low energy (70-90 kVp) and high dose (1.2 [mu]Gy/projection) optimizes low contrast detectability, while collimation around the heart improves SNR by reducing scatter. Images acquired both in vivo and in a slab phantom show that tight collimation and beam filtration result in improved SNR and a reduction of shading artifacts. Visualization of radiofrequency ablation lesions using contrast enhanced C-arm CT during the procedure provides a direct assessment of adequate lesion formation and may circumvent complications associated with cardiac ablation procedures. An in vivo validation study was completed in 9 swine by comparing lesion dimensions measured in C-arm CT images and pathology specimens. All ablation lesions were visualized and lesion dimensions, as measured on C-arm CT, correlated well with postmortem tissue measurements using triphenyltetrazolium chloride (TTC) staining (mean difference 1D dimensions: 0.09 ± 1.04 mm, area: -0.71 ± 5.86 mm2). C-arm CT visualization of myocardial infarction (MI) in the catheterization lab could furnish early prognostic information for risk stratification as well as provide 3D images for guidance of stem cell or ablation therapies. A porcine model using balloon occlusion in the coronary artery was used to study visualization of acute and subacute MI in 12 swine. Contrast enhanced C-arm CT imaging was performed the day of infarct creation or 4 weeks after infarct creation and the volume of the infarct was compared against pathology to validate the visualization of infarction. Acute MI is best visualized at 1 minute post contrast injection as a region of combined hyper- and hypoenhancement whereas subacute MI appears as a region of hyperenhancement with peak contrast enhancement at 5 minutes post contrast injection. C-arm CT infarct volumes compared well with TTC staining (mean difference acute: -0.5 cm3, subacute: -0.7cm3). In conclusion, cardiac C-arm CT with contrast and imaging protocols optimized for low-contrast detectability has been established as a consistent and reliable technique for imaging myocardial necrotic tissue in the interventional suite.

    Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates possess remarkable biocompatibility and bioactivity. Materials scientists use this property extensively to construct artificial bone grafts that are either entirely made of or only surface-coated with the biologically relevant calcium orthophosphates. Porous scaffolds made of calcium orthophosphates are very promising tools for tissue engineering applications. A comprehensive overview of calcium orthophosphates, this book highlights their importance and biomedical uses.

    Due to their unique properties, chitosan-based materials have emerged as useful resources in a variety of medicines, drug controlled-release carriers, tissue engineering scaffolds, and immobilized enzymes. But many of these materials have yet to reach the commercial market. Therefore, more work must be completed to fill the gap between research and production. Exploring the state of the field, Chitosan-Based Hydrogels: Functions and Applications details the latest progress in the research and development of chitosan-based biomaterials. The book introduces the formation and chemical structure of chitosan-based hydrogels. It also discusses the relationship between their structure and functions, which provides a theoretical basis for the design of biomaterials. In addition, many real-world examples illustrate the potential application of chitosan-based hydrogels in various areas, including materials science, biotechnology, pharmaceuticals, regenerative medicine, and cell engineering. By examining the structure and functions of chitosan-based hydrogels in living systems, this book provides the foundation for future research. It encourages readers to contribute to further research and development of these unique biomaterials.

    This book represents the first in a two-volume set on biological rhythms. This volume focuses on supporting the claim that biological rhythms are universal and essential characteristics of living organisms, critical for proper functioning of any living system. The author begins by examining the potential reasons for the evolution of biological rhythms: (1) the need for complex, goal-oriented devices to control the timing of their activities; (2) the inherent tendency of feedback control systems to oscillate; and (3) the existence of stable and powerful geophysical cycles to which all organisms must adapt. To investigate the second reason, the author enlists the help of biomedical engineering students to develop mathematical models of various biological systems. One such model involves a typical endocrine feedback system. By adjusting various model parameters, it was found that creating a oscillation in any component of the model generated a rhythmic cascade that made the entire system oscillate. This same approach was used to show how daily light/dark cycles could cascade rhythmic patterns throughout ecosystems and within organisms.

    This is the first textbook to offer a comprehensive account of ocular prosthetics and the evidence used to underpin and support this field of healthcare. It does so by bringing together information from ophthalmology, prosthetic eye and contact lens literature, and from experts actively engaged in these fields. The book describes the psychological, anatomical and physiological aspects of eye loss as well as surgical procedures for removing the eye, patient evaluation, constructing prosthetic eyes (including prosthetic and surgical techniques for dealing with socket complications), the socket's response to prosthetic eyes, prosthetic eye maintenance and the history of prosthetic eyes. Though primarily intended for prosthetists, ophthalmologists, ophthalmic nurses, optometrists and students in the fields of ocular medicine, maxillofacial medicine and anaplastology, the book also offers a useful resource for other health workers and family members who care for prosthetic eye patients, and for those patients seeking a deeper understanding of the issues affecting them than they can find elsewhere.

    Ligand-receptor interactions and the specific molecular recognition events that define them govern many important physiological processes. When these interactions become dysregulated, normal physiology quickly degenerates into disease states. Nowhere is this more evident than in metastatic cancer, where aberrant signaling drives uncontrolled cell growth and systemic dissemination of disease. In spite of much effort, the management of metastatic disease has largely remained an intractable clinical challenge as effective treatment options are limited. Protein-based biologics, which leverage the inherent affinity and specificity of protein-protein interactions, offer an effective strategy for targeting and modulating dysregulated disease pathways in order to bring them under control. In this dissertation, we use combinatorial and rational protein engineering methods to develop receptor-based therapeutics that target Axl, a receptor tyrosine kinase shown to be involved in driving metastasis and disease progression in a wide range of human cancers. Using yeast-surface display and directed evolution, Axl variants were engineered for improved binding to Gas6, Axl's activating ligand. To gain an understanding of the molecular basis of the increased binding, detailed biochemical and structural studies were performed, including solving the structure of a high affinity Axl variant in complex with Gas6. When reformatted for in vivo applications, the engineered Axl decoy receptors were found to have apparent affinities to Gas6 as low as 93 fM, which are among some of the strongest protein-protein interactions ever reported. Importantly, when tested in a panel of aggressive mouse models of metastatic disease, the engineered decoy receptors showed significant efficacy, reducing metastatic disease by up to 95%. Collectively, these results validate Axl as a therapeutic target in metastatic disease and highlight the potential clinical value of the engineered Axl decoy receptors as novel anti-metastatic therapies.

    Dynamic susceptibility-contrast perfusion-weighted imaging (DSC PWI) is a magnetic resonance imaging (MRI) technique that measures the delivery of arterial blood to the tissue capillary bed using a contrast agent. DSC PWI can reveal important information in stroke patients by assessing hypoperfused brain tissue, while in tumor patients it is used to evaluate the tumor vasculature. For clinical applications, DSC PWI relies on both accurate and rapid image formation. Gradient-echo echo-planar imaging (EPI) is the most commonly used MRI pulse sequence for DSC PWI, mainly due to its fast image acquisition capability, a relatively high contrast-to-noise ratio, and its availability on most clinical MRI systems. However, quantification of perfusion parameters with gradient-echo EPI remains challenging. Gradient-echo EPI is most sensitive to larger vessels, including arteries and veins. These measurements do not provide specific information about true perfusion within the microvasculature, the site of oxygen and nutrient extraction to brain tissue. To acquire perfusion measurements that are more confined to the microvasculature, spin-echo EPI acquisition techniques have been proposed. Spin-echo EPI is most sensitive to smaller vessels, providing a clear advantage over gradient-echo EPI. Unfortunately, spin-echo EPI suffers from lower sensitivity to the contrast agent passage, and the determination of arterial contrast agent concentrations required for quantitative perfusion MRI remains an unsolved problem when using spin-echo EPI data. In the first part of this dissertation, a combined approach for simultaneous spin- and gradient-echo (SAGE) perfusion MRI is presented. The proposed imaging technique combines the advantages of higher overall sensitivity to contrast agent passage of gradient-echo EPI with superior microvascular selectivity of spin-echo EPI, resulting in complementary perfusion information. The combined method enabled improved detection of abnormal brain perfusion compared to conventionally processed DSC PWI data, as illustrated in cases of stroke and brain tumors. Specifically, reduced sensitivity to larger blood vessels of spin-echo data generated from SAGE perfusion MRI measurements improved the visibility of hypoperfused tissue. In the second part, the gradient-echo and spin-echo signal contributions to the proposed SAGE perfusion MRI acquisition technique are analyzed in detail. The development of an optimized pair of MRI excitation and refocusing pulses enhanced the contrast-to-noise ratio of the spin-echo signal. Moreover, augmented perfusion parameter estimation improved the accuracy of both gradient-echo and spin-echo signals to reduce perfusion quantification errors. In the last part, implications of contrast agent leakage from the brain vasculature are discussed. Considerable contrast agent extravasation, caused by blood-brain barrier leakage commonly observed in brain tumors and subacute strokes, results in additional quantification errors of brain perfusion parameters. To mitigate these errors, pharmacokinetic modeling of contrast agent distribution was applied to SAGE perfusion MRI data. Intravascular contrast agent concentrations could then be separated from extravascular concentrations, resulting in leakage-corrected perfusion data. Moreover, the applied pharmacokinetic modeling approach facilitated the extraction of permeability parameters. The combined evaluation of perfusion and permeability parameters, derived from SAGE perfusion MRI data, showed potential utility in brain tumor imaging with the goal of improving the diagnostic value of perfusion MRI in the assessment of brain tumor progression.
