- High deductible health insurance plans have been advocated as a measure to control rising healthcare expenditure, by reducing the moral hazard associated with 3rd party insurance and encouraging cost-effective behavior. Despite the increasing use of demand-side cost-sharing, the optimal design of health insurance schemes is not very well understood nor easy to apply. As such, economic theory has not had a major influence on design of health insurance schemes. This dissertation examines aspects of designing and implementing high deductible insurance schemes. First, I examine the optimal coinsurance rates of primary prevention, diagnostic services and office visits. In many observed health plans, these services are often exempt from deductibles. The Affordable Care Act also mandates that private health plans must cover a stipulated list of preventive services at zero coinsurance with no deductible. I show that optimal coinsurance rates for primary prevention are always higher than the coinsurance rates for associated treatment for risk-neutral individuals; and if the uninsured portion of treatment expenditure is sufficiently large or probability of illness is sufficiently small for risk-averse individuals. This probability is given by the threshold under which a risk-averse individual will undertake more prevention. We also identify similar thresholds for diagnostic services and they show that optimal coinsurance rates are always higher than associated treatment coinsurance in most circumstances. These results suggest that additional justifications have to be sought in setting prevention and diagnostic coinsurance below that of treatment. This dissertation also develops an easily applicable formula for optimal nonlinear coinsurance rates using a perturbation method. This method has the advantage of being extended to solve optimal deductible levels with fixed coinsurance rates as compared to Blomqvist(1997)'s derivation using optimal control theory. The application of this formula to observed health insurance plans, distribution of expenditures and risk aversion provides maximum bounds (in absolute terms) for elasticity estimates. Similarly from elasticity estimates, we can also obtain lower bounds of risk aversion. I apply these formulas to generate optimal coinsurance rates and deductible levels for observed expenditure distributions and elasticities in the RAND HIE. Finally, I study Medical Savings Accounts (MSAs) which are usually coupled to high deductible health insurance schemes. The effectiveness of MSAs depends on the extent to which consumers value Medisave dollars less compared to cash dollars because of restrictions imposed on the use of MSAs. Using individual-level data of hospital ward choice in Singapore, we estimate that consumers value Medisave dollars at 80 cents to a dollar in cash.
- Optimal experimental design with R 2011CRCnetBASE"Experimental design is often overlooked in the literature of applied and mathematical statistics: statistics is taught and understood as merely a collection of methods for analyzing data. Consequently, experimenters seldom think about optimal design, including prerequisites such as the necessary sample size needed for a precise answer for an experimental question. Providing a concise introduction to experimental design theory, Optimal Experimental Design with R: Introduces the philosophy of experimental design Provides an easy process for constructing experimental designs and calculating necessary sample size using R programs Teaches by example using a custom made R program package: OPDOE. Consisting of detailed, data-rich examples, this book introduces experimenters to the philosophy of experimentation, experimental design, and data collection. It gives researchers and statisticians guidance in the construction of optimum experimental designs using R programs, including sample size calculations, hypothesis testing, and confidence estimation. A final chapter of in-depth theoretical details is included for interested mathematical statisticians"--Back cover.
- Mathematical models of health systems and disease can provide important information to decision makers when direct experimentation is impossible, impractical, or unethical, and when there are many possible decision alternatives. When costs or benefits of a medical or health policy decision are in the distant future (perhaps decades away) or are borne by other members of society, mathematical models may be the only practical way to fully evaluate the costs and consequences of policy alternatives. Through modeling, the decision maker can develop a deeper understanding of which factors have the greatest impact on the outcome of interest and explicitly explore decision uncertainty. This dissertation applies and extends the use of mathematical models in the application area of health policy -- specifically to applications of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) screening in injection drug users (IDUs) and the general population.
- Optimization and evaluation of scanning-beam digital X-ray tomosynthesis for real-time 3D image guidance for lung tumor biopsies 2013Biopsy methods used in lung cancer typically have either significant complication rates or high rates of false negatives. The safest biopsy method (transbronchial biopsy) has high false negative rates. This thesis takes the initial steps towards adding real-time 3-dimensional imaging to this process via tomosynthesis. Currently transbroncial biopsies are guided by an Electromagnetic Navigation Bronchoscopy (ENB) system. This guidance assumes little physiological change between the CT scan and the procedure and also assumes that there is no movement of the catheter while removing the ENB probe from the working channel and inserting the needle or cytobrush for the biopsy. Thus the pulmonologist is 'blind' during the actual biopsy. The scanning-beam digital x-ray (SBDX) system (an inverse geometry fluoroscopic system) can add tomosynthesis imaging to the biopsy process. The SBDX system has a 2D array of small beams incident from multiple angles onto a small detector. The multiple angles allows 3-dimensional information to be reconstructed in the images via tomosynthesis. To maximize the tomographic angle of the SBDX system, the tomosynthetic angle as a function of tumor-to-detector distance (TDD) was calculated. Monte Carlo Software (PCXMC) was used to calculate organ doses and effective dose for source-to-detector distances (SDDs) for multiple system geometries. These calculations were performed for both the SBDX system and for standard fluoroscopy. The effect of system geometry on patient dose, both in absolute terms and in terms of image quality were investigated. The tomographic angle had more significant changes with SDD in the region near the detector, at a source to tumor distance that is 69.7% of the SDD assuming constant source and detector size. Changing the patient location in order to increase tomographic angle has a significant effect on organ dose distribution due to geometrical considerations. When tumor signal to noise ratio (SNR) is held constant (ie. x-ray fluence is scaled appropriately), SBDX gives 2-10 times less dose than fluoroscopy for the same conditions within the typical range of patient locations. These models suggested an ideal SDD of 100 cm because of practical considerations of varying patient size, and adequate room between the patient and the bracing securing the detector. To show that the SBDX could improve targeting of tumor lesions, realistic phantoms were needed. Pig lungs and hearts were preserved, the vasculature was filled, and lesions were created in them. The lungs were capable of breathing motion when placed in a custom vaccum chamber. A chest phantom with a rib cage was cut to fit in the vacuum chamber. This provided a very lifelike phantom model for the lungs including the capacity to mimic breathing motion. The prepared lungs were scanned by CT and the scans were used for ENB planning. The pulmonologist placed fiducials which represented the tissue sample site using the ENB system. During this process, the lungs were deformed to simulate the real clinical condition of breathing. After all the fiducials were placed, the lungs were scanned on the SBDX system. The shortest distance from the distal tip of the fiducial to the center of the lesion was measured using the SBDX images. The lungs were again scanned by CT and the fiducial-to-lesion distances were measured. The SBDX system fiducial-to-lesion distances had significant (p< 0.0001) agreement with the CT fiducial-to-lesion distances, indicating that SBDX images can accurately provide image guidance for ENB procedures. The ENB tip-to-target distances were not accurate. When auto-registered lungs were compared with manually registered lungs, it was found that the auto-registered lungs, which had less CT-to-body divergence, had more agreement with the CT fiducial-to-lesion measurements. This indicates that CT-to-body divergence both from rigid registration of primary bronchial passages and non-rigid breathing motion is responsible for the ENB inaccuracy in the distal regions of the lungs. Additional steps to bring this method to the clinic include testing with both guidance systems concurrently, continued development of the reconstruction algorithm, and testing the system in an in vivo model.

- Optimizing patient treatment decisions in an era of rapid technological advances : models and insights 2013How can chronically ill patients make the best treatment decisions when there is uncertainty about the costs and effectiveness of new and emerging treatments? We investigate this question by evaluating new medical technologies and interventions focusing on chronic hepatitis C virus (HCV) infection. Chronic HCV affects approximately 3 million Americans and has been historically difficult to treat. New and emerging treatments show great promise in providing better health outcomes, but at a significantly higher cost. Using decision-analytic Markov models, we first examine the cost-effectiveness of various disease monitoring strategies before treatment initiation, and the improved use of a new genetic marker-guided therapy to target HCV treatment to patients. We then investigate the cost-effectiveness of population screening policies to detect and treat the estimated 2 million Americans who are unaware of their chronic HCV infection. Motivated by this applied work, we consider the general theoretical question of how long a patient with a treatable chronic disease should wait for more effective treatments to emerge before undergoing currently available treatment. This decision involves a difficult tradeoff between the deterioration of a patient's health and the magnitude of technological improvement over time. We model the patient-level treatment adoption decision problem as an optimal stopping problem using a discrete-time, finite-horizon Markov Decision Process framework. We present structural properties of the model, analytical results, and a numerical example for chronic HCV treatment. Results of this work can inform both individuals and organizations in making treatment decisions in the presence of rapid medical technology advancement.

- Options in the management of the open abdomen 2015SpringerThis book by Madbak and Dangleben has collated lot of information that has been presented and published in many disparate arenas into a single easy to read source. In an area where there is more experience and ℓ́ℓfavorite techniquesℓ́ℓ than true evidence based answers, they provide a wealth of information along with outstanding photographic support that makes this an excellent resource for all surgeons caring for this population. Similar to many things in life, when treating patients with the open abdomen one size or methodology does not fit all and this book will assuredly contain at least one possible answer to your patientℓ́ℓs problem. One of the more unique aspects of this textbook is its detailed ℓ́ℓHow toℓ́ℓ approach for the wide variety of techniques utilized in the management of the open abdomen. While there may be no consensus as to what constitutes the optimal management of the open abdomen, this book articulates a number of options and their advantages. Most importantly, it provides high quality photographs that enhance the step by step ℓ́ℓHow toℓ́ℓ approach of the text. More recent developments including using biologic mesh, implementing complex abdominal wall reconstruction and utilizing minimally invasive endoscopic techniques are described. This book is not only appropriate for all practicing surgeons that deal with this complex issue, but is also relevant for residents and fellows who are just getting their first exposure to open abdomens.
- Anxiety, a sustained state of apprehension in the absence of a specific and imminent threat, is critical for an organism to survive in an environment with unpredictable risks. In disease states, however, anxiety becomes severely debilitating; anxiety disorders represent the most common psychiatric diseases (28% lifetime prevalence). Despite the high prevalence of anxiety disorders, current treatments are often ineffective and have severe side-effects, such as addiction, pointing to the need for a deeper understanding of anxiety circuits. The amygdala and extended amygdala have long been hypothesized to play a central role in anxiety, but the function of the intra- and inter-connections of the amygdala and extended amygdala circuits are unclear, largely due to the lack of appropriate tools. With the advent of optogenetics, which was pioneered in the Deisseroth lab, and with the evolution of virus- or promoter-based targeting strategies, it is now possible to manipulate a specific circuit element with unprecedented precision and to identify its function in behavior. The first part of this thesis illustrates the application of optogenetics to identify an intra-amygdala circuit element that decreases anxiety. The second part explores the functional circuitry of the bed nucleus of the stria terminalis (BNST), a key component of the extended amygdala. We studied the roles of its input from the amygdala and outputs to the hypothalamus and brainstem areas in the anxious state. Here, the term 'anxious state' is used to emphasize that anxiety is a behavioral state consisting of distinct features, such as behavioral risk-avoidance and changes in respiration rate. We sought to find circuit elements mediating each distinct feature of the anxious state. The data provided by this thesis furthers our understanding of the function and dysfunction of anxiety circuitry. The approach that we employed here for functional circuit mapping may be applicable to the dissection of other behavioral states, such as fear and aggression.
- The neural control of sleep and wakefulness depends upon a complex and partially defined balance between subcortical excitatory and inhibitory populations in the brain. Wake-active neurons include hypocretin (Hcrt)-containing neurons in the lateral hypothalamus and noradrenergic neurons that make up the brainstem locus coeruleus (LC). Experimentally determining a causal role for these neurons in promoting and maintaining wakefulness has remained elusive using traditional pharmacological and electrical techniques due to their small size, unique morphology, and proximity to heterogeneous neuronal and non-neuronal cell types. The recent development of optogenetic technology provides a toolkit of genetically-encodable, millisecond timescale, stimulation and inhibition probes that can be targeted to specific cell types with no toxicity to the cells under investigation. This dissertation discusses the application of optogenetic tools to questions about sleep/wake circuitry and uses these tools to study Hcrt and LC neurons, both individually and in combination.
- Optogenetic neuromodulation is giving scientists an unprecedented ability to modulate neural circuits, providing specificity with regards to location, cell type, as well as neuromodulatory effect. On the other hand, electrical stimulation and lesions, methods commonly used to study neural circuits, are lacking in specificity, often affecting both local cells and passing axons, as well as multiple cell types. Our laboratory has been at the forefront of the field of optogenetics, having developed, for use in mammalian systems, Channelrhodopsin-2 (ChR2), an algal light-activated cation channel that depolarizes neurons in response to blue light, and Natronomonas pharaonis halorhodopsin (eNpHR), a chloride pump that hyperpolarizes neurons in response to amber light. These proteins can control neuronal activity with millisecond timescale precision, and through promoters, they can be targeted to specific cell-types in heterogeneous tissue. Along with its specificity, light stimulation with optogenetic tools often allows the recording of neural activity without the artifact that obfuscates recordings with electrical stimulation. The advantages provided by optogenetics allowed us to make a breakthrough in determining the therapeutic mechanism of deep brain stimulation, a robust treatment for Parkinson's disease in which stimulating electrodes are implanted deep in the brain. Using optogenetics, we replicated the effect of deep brain stimulation by modulating cortical inputs into the region where the stimulating electrode is normally placed. Combined with other corroborating publications, a hypothesis is emerging that electrical stimulation deep in the brain actually produces its effect by modulating cortical projections to the deep brain region. Based on this concept, several clinical studies are being done to better understand the cortical role in Parkinson's disease and determine whether cortical stimulation (potentially non-invasive), could be an alternative to the invasive implants currently used. In order to perform these experiments, we studied the transmission of visible light in brain tissue to estimate the volume of activation produced by optogenetic stimulation and developed a device to measure fluorescence in awake, behaving animals, allowing the quantification of virally transfected gene expression over time, as well as the localization of expression along axon bundles. The knowledge gained from these experiments will have a significant impact on future experiments in the broader field of optogenetics.
- Optogenetic tool development and application to dissecting dopaminergic circuitry in social behavior 2012Social interaction is an essential and highly integrative behavioral task that is impaired in major psychiatric disorders such as autism, schizophrenia, social anxiety disorder, and depression. Current treatments for many of these disorders are based on pharmacological approaches that have been used for decades even though their mechanisms of action are poorly understood and carry many side effects. In particular, treatment of the asocial symptoms of these disorders has remained elusive due to a generally poor understanding of the neural circuitry underlying normal social behavior. In order to move toward a deeper circuit-level understanding of these complex neural processes, our lab has pioneered the use of two light-activated microbial opsins, Channelrhodopsin-2 (ChR2) and Halorhodopsin (NpHR), to achieve precise bidirectional optogenetic control of specific cell types in behaving animals. However, it has become clear that the complexity of the circuitry involved in psychiatric behaviors will require new classes of optogenetic tools to modulate cells in a more refined manner based on characteristics such as projection profile, receptor expression, and endogenous firing patterns. The purpose of this study was thus two-fold: 1) to develop novel optogenetic tools for more physiologically relevant stimulation of different cell types on different timescales, and 2) to apply these tools to define in socializing animals the real-time causal role not only of a specific brain region and cell type, but also of distinct subpopulations defined by projections to different downstream brain regions and distinct downstream cell types. The engineered opsins we develop here will be generalizable to dissect other neural circuits in health and disease, enabling new domains of optogenetic investigation that have thus far been inaccessible, and enhancing the precision of optical neural control in a broad variety of settings.
- Optogenetic tool development and interrogation of frequency-dependent signaling in the hippocamposeptal pathway 2013Hippocampal oscillations are critical for information processing, and are strongly influenced by inputs from the medial septum. Hippocamposeptal neurons provide direct inhibitory feedback from the hippocampus onto septal cells, and are therefore likely to also play an important role in the circuit; these neurons fire at either low or high frequency, reflecting hippocampal network activity during theta oscillations or ripple events, respectively. Since the hippocamposeptal projection is sparse and long-range, the impact of high or low frequency hippocampal input on septal physiology has not been addressable with classical electrophysiological or pharmacological techniques. In order to understand the contribution of defined neuronal subtypes, such as hippocamposeptal neurons, to brain function, our laboratory has developed a technique termed optogenetics, which integrates genetic targeting and optical stimulation to achieve temporally precise manipulation of genetically and spatially defined cell types in intact tissue. Optogenetics employs light sensitive microbial proteins, including ion pumps and channels that can elicit or inhibit action potentials. Optogenetics has already proved invaluable to neuroscience, but several key limitations to its application have become apparent: First, increasingly diverse optogenetic tools allow more versatile control over neural activity, but since new tools have been developed in multiple laboratories and tested across different preparations it is difficult to draw direct comparisons between them. As a result, it has become increasingly challenging for end users to select the optimal reagents for their experimental needs. Second, as the power of genetically encoded interventional and observational tools for neuroscience expands, the boundary of experimental design is increasingly defined by limits in selectively expressing these tools in specific cell types. To date, cell-type has primarily referred to genetic specificity, achieved with promoter-driven expression either in transgenic animals or in viruses. This approach is limited in its ability to define a 'cell type': cells may be targeted based on only a single parameter, and genetic targeting does not take into account anatomic connectivity, in many cases the most salient feature of a target population. The aim of this thesis is thus three-fold: 1) To interrogate frequency-dependent signaling in the hippocamposeptal pathway, using optogenetics to gain cell-type specific, temporally-precise control over hippocamposeptal fibers, 2) To systematically compare microbial opsins under matched experimental conditions to extract essential principles and identify key parameters for the conduct, design and interpretation of experiments involving optogenetic techniques, and 3) To develop new viral and molecular strategies to target cells of interest based on both genetic and topological parameters. The investigation of the hippocamposeptal projection will increase our understanding of the larger circuit of which it is a part, and will also illustrate the importance of firing frequency in neuronal signaling. The tool development described will be useful for future work investigating the hippocamposeptal pathway in particular, and more generally for a broad variety of applications of optogenetics to neuroscience.

- Oral cancer-- diagnosis and therapy 2015SpringerOral cancer is frequently diagnosed late, when the disease has advanced with lesions that are large and deeply invasive and with metastasis to regional lymph nodes, leading to increased mortality. Moreover, late diagnosis and treatment often result in considerable morbidity of oral and maxillofacial structures and poor appearance and function following therapy. This book provides head and neck oncologists, oral oncologists, oral and maxillofacial surgeons, medical oncologists, dentists and other members of dental teams furnishing supportive care with a systematic review of recent diagnostic and therapeutic advances in oral cancer. The various authoritative chapters are prepared by specialists who are active leaders in each basic and clinical field. All chapters address individual and collective issues that arise in managing oral cancer patients with difficult treatment problems and provide insight into the multiple valid management approaches available. The authors offer an extensive source of information about oral cancers and encourage the clinician to be flexible and innovative, giving physicians and medical personnel the background information to make the best, educated, responsible decisions for individual patients.

- The origin of modern intensive care units (ICUs) has frequently been attributed to the widespread provision of mechanical ventilation within dedicated hospital areas during the 1952 Copenhagen polio epidemic. However, modern ICUs have developed to treat or monitor patients who have any severe, life-threatening disease or injury. These patients receive specialized care and vital organ assistance such as mechanical ventilation, cardiovascular support, or hemodialysis. ICU patients now typically occupy approximately 10% of inpatient acute care beds, yet the structure and organization of these ICUs can be quite different across hospitals. In The Organization of Critical Care: An Evidence-Based Approach to Improving Quality, leaders provide a concise, evidence-based review of ICU organizational factors that have been associated with improved patient (or other) outcomes. The topics covered are grouped according to four broad domains: (1) the organization, structure, and staffing of an ICU; (2) organizational approaches to improving quality of care in an ICU; (3) integrating ICU care with other healthcare provided within the hospital and across the broader healthcare system; and (4) international perspectives on critical care delivery. Each chapter summarizes a different aspect of ICU organization and targets individual clinicians and healthcare decision makers. A long overdue contribution to the field, The Organization of Critical Care: An Evidence-Based Approach to Improving Quality is an indispensable guide for all clinicians and health administrators concerned with achieving state-of-the-art outcomes for intensive care.

- My Ph.D. work primarily involves the synthesis of ethylene-based oligomers and ethylene-styrene copolymers using organometallic catalysis. Chapter 1 reviews selective ethylene oligomerization that produces 1-hexene and 1-octene, with particular emphasis on the chromium-based catalytic systems and the mechanism by which they operate. Its application to the preparation of value-added chemicals is also covered. Chapter 2 and Chapter 3 present investigations on selective ethylene oligomerization with a Cr(PNP)Cl3/MAO catalyst system (PNP = Ph2PN(iPr)PPh2) in the presence of dialkyl zinc as an effective strategy for the co-generation of 1-octene and functionalized ethylene oligomers. Transmetallation with ZnMe2 during Cr-catalyzed ethylene tetramerization generated end-labeled 1-alkenes in Cn> 10 along with 1-octene, while that with ZnEt2 or ZnBu2 produced a mixture of end-labeled linear alkanes and 1-alkenes in Cn> 10 as well as 1-octene. Labeling studies with D2O provided a mechanistic test for metallacycle intermediates. Mechanistic proposals are presented to explain the formation of end-labeled products in the presence of various types of zinc alkyls. Chapter 4 and Chapter 5 examine a series of titanocenes [CpTiCl3, CpTiCl2TEMPO, CpNTiCl3, CpNTiCl2TEMPO, where Cp = C5H5, CpN = C5H4CH2CH2N(CH3)2, and TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl] for styrene homopolymerization and ethylene-styrene (ES) copolymerization at 70 °C and 120 °C to determine the influence of the pendant amine group and the hydroxylaminato ligand on comonomer incorporation and distribution. Titanocenes bearing the pendant amine ligand were active for ES copolymerization, whereas complexes lacking the pendant group afforded only mixtures of homopolymers, revealing the critical role of the pendant amine donor on the copolymerization behavior. At 120 °C, the titanocene complexes with the amine group generated high molecular weight ES copolymers along with an atactic polystyrene (aPS) byproduct. The molecular weight of the ES copolymers produced by a coordination mechanism was found to coincide with that of the aPS produced by a radical polymerization mechanism. A method to separate these two components was developed by the addition of a catalytic chain-transfer agent, cobalt tetraphenylporphyrin, successfully decreasing the molecular weight of the radically-produced aPS and offering expedient separation of the ES copolymer from the aPS. Chapter 6 describes a series of new mono-, bi-, and trimetallic complexes based on the dinucleating ligand, N, N'-bis[2-(diphenylphosphino)phenyl] formamidine (PNNP), which provides two binding sites suitable for accommodating Pd, Ni, Co, Fe, and Cu. Definitive evidence for the structures of all complexes were given by X-ray crystal structures. The synthesis, characterization and crystal structure of each complex are discussed.

- A fundamental characteristic of metazoans is the formation of a simple, polarized epithelium. In higher animals, the structural integrity and functional polarization of simple epithelia require a cell-cell adhesion complex containing a classical cadherin, the Wnt-signaling protein [Beta]-catenin and the actin-binding protein [Alpha]-catenin. I have investigated the evolutionary origins of epithelial cell polarity and of the cadherin-catenin complex. I show that the non-metazoan Dictyostelium discoideum forms a polarized epithelium that is essential for multicellular development. Although D. discoideum lacks a cadherin homolog, I have identified and characterized an [Alpha]-catenin ortholog that binds a [Beta]-catenin-related protein. Both proteins are essential for formation of the epithelium, polarized protein secretion and proper multicellular morphogenesis. Thus the organizational principles of metazoan multicellularity may be more ancient than previously recognized, and the role of the catenins in cell polarity predates the evolution of Wnt signaling and classical cadherins.

- Actin-based cell migration depends on the temporal and spatial integration of multiple force-generating systems. Polymerization of the actin network drives protrusion of the cell membrane, and the stretched membrane, in turn, exerts force on the actin network. Myosin contraction of the viscoelastic actin network is balanced by cell-substrate adhesion. The molecular components that contribute to each of these forces - actin-based protrusion, membrane tension, myosin-mediated contraction, and adhesion - have been extensively characterized, but the manner in which they are integrated in vivo to give rise to large-scale emergent properties such as cell shape and movement is not well understood. This thesis describes the role of cell-substrate adhesion in large-scale actin network organization and dynamic cell shape determination. Keratocytes exhibit several non-steady-state behaviors, including oscillatory retraction of the trailing edge, waves of protrusion at the leading edge, and symmetry breaking and motility initiation. I have shown that the mechanical and biochemical properties of adhesions contribute to each of these dynamic behaviors. Oscillatory retraction of the trailing edge emerges in fast-moving, fan-shaped keratocytes and I present evidence consistent with a mechanical model in which elastic coupling between the front of the cell and adhesions in the rear drives oscillations. In contrast, I have found that protrusion waves at the leading edge are likely the result of the biochemical, rather than mechanical, properties of adhesions. Traveling waves emerge at high adhesion strengths and adhesion maturation is required for waving. Mature adhesions have been shown previously to bind several components that contribute to leading edge protrusion, including VASP, a protein that promotes actin polymerization by preventing barbed end capping. Dynamic localization of VASP to the leading edge in waving keratocytes is consistent with a reaction-diffusion model in which global depletion of VASP by mature adhesion, in conjunction with local depletion by the polymerizing actin network, results in lateral propagation of protrusion waves. Finally, I present evidence that suggests that balance between cell-substrate adhesion and myosin contraction sets the mechanical instability threshold above which stationary, radially symmetric keratocytes break symmetry and begin to move. On the whole, the work described here represents significant progress towards elucidating the self-organization principles that underly whole cell migration.
