Models of Anaerobic Infection: Proceedings of the third Anaerobe Discussion Group Symposium held at Churchill College, University of Cambridge, July 30-31, 1983, followed by the abstracts of the first meeting of the Society for Intestinal Microbial Ecology and Disease, Boston, November 1983 (New Perspectives in Clinical Microbiology #10)

by M. J. Hill

The ADG held its first International Symposium at Churchill College, Cambridge, in July 1979. The second symposium was also held at Churchill College on 30-31 July, 1981, and this, the third, took place at the same college on 30-31 July,. 1983. The meeting was structured in a format which we hoped would appeal to the full range of our membership. The philosophy of the ADG is that medical microbiologists, veterinarians, toxicologists and dental bacteriologists have much to learn from each other and can best be achieved by bringing these various disciplines together frequently and in informal surroundings. Again the symposium was very generously sponsored by May and Baker Limited who met all costs of the meeting and entertained us splendidly. David Jackson and Donald Bedford were re­ sponsible for coordinating with the ADG on behalf of May and Baker and, as usual, gave us their full cooperation. This book contains the full-length papers, followed by the posters presented at the meeting. This book also serves as a vehicle for the abstracts of the first meeting of the Society for Intestinal Microbial Ecology and Disease, SIMED, held in Boston, Massachusetts. An introduction to this new society by its President, Sydney M. Finegold, M.D., precedes the abstracts. M.J.

Models of Calcium Signalling: Mathematical Modeling Of Calcium Dynamics And Signal Transduction (Interdisciplinary Applied Mathematics #43)

by Geneviève Dupont Martin Falcke Vivien Kirk James Sneyd

This book discusses the ways in which mathematical, computational, and modelling methods can be used to help understand the dynamics of intracellular calcium. The concentration of free intracellular calcium is vital for controlling a wide range of cellular processes, and is thus of great physiological importance. However, because of the complex ways in which the calcium concentration varies, it is also of great mathematical interest.This book presents the general modelling theory as well as a large number of specific case examples, to show how mathematical modelling can interact with experimental approaches, in an interdisciplinary and multifaceted approach to the study of an important physiological control mechanism.Geneviève Dupont is FNRS Research Director at the Unit of Theoretical Chronobiology of the Université Libre de Bruxelles; Martin Falcke is head of the Mathematical Cell Physiology group at the Max Delbrück Center for Molecular Medicine, Berlin; Vivien Kirk is an Associate Professor in the Department of Mathematics at the University of Auckland, New Zealand; James Sneyd is a Professor in the Department of Mathematics at The University of Auckland, New Zealand.

Models of Depressive Disorders: Psychological, Biological, and Genetic Perspectives (The Depressive Illness Series #2)

by J. John Mann

This volume is the second in a series on depressive illness. The first volume, entitled Phenomenology of Depressive Illness, is de­ voted to a description of depressive illness from many vantage points including that of the patient as well as the psychiatrist. Epidemiological, nosological, and developmental aspects are included together with specific descriptions of major subtypes of depressive illness. It is only after an illness is fully described that an attempt should be made to generate models with ex­ planatory and predictive properties. This second volume is that next step. The major models of depressive illness are described. The limited progress that has been made in integrating these models is discussed, but with further knowledge, this will change. Each model has different advantages and may apply more directly to different subtypes of depressive illness. Such refinements also await the results of future studies. However, the heuristic and clinical usefulness of the models described is considerable and will inform the reader about the current state of knowledge regarding the etiology and pathogenesis of de­ pressive illness and directions of future research. J. John Mann, M.D. New York vii ACKNOWLEDGMENTS This volume would not have been possible without the support of my wife and children who permitted me the time to work on it. Ms. Renee Azima-Heller assisted greatly in the organi­ zation of the material for the book. A career scientist award from the Irma T. HirschI Trust provided support for this work.

Models of Horizontal Eye Movements: Part 4, A Multiscale Neuron and Muscle Fiber-Based Linear Saccade Model (Synthesis Lectures on Biomedical Engineering)

by Alireza Ghahari John D. Enderle

There are five different types of eye movements: saccades, smooth pursuit, vestibular ocular eye movements, optokinetic eye movements, and vergence eye movements. The purpose of this book series is focused primarily on mathematical models of the horizontal saccadic eye movement system and the smooth pursuit system, rather than on how visual information is processed. In Part 1, early models of saccades and smooth pursuit are presented. A number of oculomotor plant models are described here beginning with the Westheimer model published in 1954, and up through our 1995 model involving a 4th order oculomotor plant model. In Part 2, a 2009 version of a state-of-the-art model is presented for horizontal saccades that is 3rd-order and linear, and controlled by a physiologically based time-optimal neural network. Part 3 describes a model of the saccade system, focusing on the neural network. It presents a neural network model of biophysical neurons in the midbrain for controlling oculomotor muscles during horizontal human saccades. In this book, a multiscale model of the saccade system is presented, focusing on a multiscale neural network and muscle fiber model. Chapter 1 presents a comprehensive model for the control of horizontal saccades using a muscle fiber model for the lateral and medial rectus muscles. The importance of this model is that each muscle fiber has a separate neural input. This model is robust and accounts for the neural activity for both large and small saccades. The muscle fiber model consists of serial sequences of muscle fibers in parallel with other serial sequences of muscle fibers. Each muscle fiber is described by a parallel combination of a linear length tension element, viscous element, and active-state tension generator. Chapter 2 presents a biophysically realistic neural network model in the midbrain to drive a muscle fiber oculomotor plant during horizontal monkey saccades. Neural circuitry, including omnipause neuron, premotor excitatory and inhibitory burst neurons, long lead burst neuron, tonic neuron, interneuron, abducens nucleus, and oculomotor nucleus, is developed to examine saccade dynamics. The time-optimal control mechanism demonstrates how the neural commands are encoded in the downstream saccadic pathway by realization of agonist and antagonist controller models. Consequently, each agonist muscle fiber is stimulated by an agonist neuron, while an antagonist muscle fiber is unstimulated by a pause and step from the antagonist neuron. It is concluded that the neural network is constrained by a minimum duration of the agonist pulse, and that the most dominant factor in determining the saccade magnitude is the number of active neurons for the small saccades. For the large saccades, however, the duration of agonist burst firing significantly affects the control of saccades. The proposed saccadic circuitry establishes a complete model of saccade generation since it not only includes the neural circuits at both the premotor and motor stages of the saccade generator, but it also uses a time-optimal controller to yield the desired saccade magnitude.

Models of Horizontal Eye Movements: Part 3, A Neuron and Muscle Based Linear Saccade Model (Synthesis Lectures on Biomedical Engineering)

by Alireza Ghahari John D. Enderle

There are five different types of eye movements: saccades, smooth pursuit, vestibular ocular eye movements, optokinetic eye movements, and vergence eye movements. The purpose of this book series is focused primarily on mathematical models of the horizontal saccadic eye movement system and the smooth pursuit system, rather than on how visual information is processed. A saccade is a fast eye movement used to acquire a target by placing the image of the target on the fovea. Smooth pursuit is a slow eye movement used to track a target as it moves by keeping the target on the fovea. The vestibular ocular movement is used to keep the eyes on a target during brief head movements. The optokinetic eye movement is a combination of saccadic and slow eye movements that keeps a full-field image stable on the retina during sustained head rotation. Each of these movements is a conjugate eye movement, that is, movements of both eyes together driven by a common neural source. A vergence movement is a non-conjugate eye movement allowing the eyes to track targets as they come closer or farther away. In Part 1, early models of saccades and smooth pursuit are presented. A number of oculomotor plant models are described therein beginning with the Westheimer model published in 1954, and up through our 1995 model involving a 4th-order oculomotor plant model. In Part 2, a 2009 version of a state-of-the-art model is presented for horizontal saccades that is 3rd-order and linear, and controlled by a physiologically based time-optimal neural network. In this book, a multiscale model of the saccade system is presented, focusing on the neural network. Chapter 1 summarizes a whole muscle model of the oculomotor plant based on the 2009 3rd-order and linear, and controlled by a physiologically based time-optimal neural network. Chapter 2 presents a neural network model of biophysical neurons in the midbrain for controlling oculomotor muscles during horizontal human saccades. To investigate horizontal saccade dynamics, a neural circuitry, including omnipause neuron, premotor excitatory and inhibitory burst neurons, long lead burst neuron, tonic neuron, interneuron, abducens nucleus, and oculomotor nucleus, is developed. A generic neuron model serves as the basis to match the characteristics of each type of neuron in the neural network. We wish to express our thanks to William Pruehsner for drawing many of the illustrations in this book.

A vergence movement is a non-conjugate eye movement allowing the eyes to track targets as they come closer or farther away. In this book, early models of saccades and smooth pursuit are presented. The smooth pursuit system allows tracking of a slow moving target to maintain its position on the fovea. Models of the smooth pursuit have been developed using systems control theory, all involving a negative feedback control system that includes a time delay, controller and plant in the forward loop, with unity feedback. The oculomotor plant and saccade generator are the basic elements of the saccadic system. The oculomotor plant consists of three muscle pairs and the eyeball. A number of oculomotor plant models are described here beginning with the Westheimer model published in 1954, and up through our 1995 model involving a 4$^{th}$ order oculomotor plant model. The work presented here is not an exhaustive coverage of the field, but focused on the interests of the author. In Part II, a state-of-art model of the saccade system is presented, including a neural network that controls the system.

Models of Mental Disorders: A New Comparative Psychiatry

by William T. McKinney Jr.

My ideas for this book have been evolving over the last several years as I have been working in the animal modeling area and have seen it change rather dramatically. There have been tremendous advances, both in methodology and in conceptualization, yet the literature is scattered in journals encompassing many disciplines. In particular, there have been only very limited attempts to write about the philosophical, conceptual, and controversial issues in this field; to pull together diverse findings; and to provide some general perspective on its future. As will probably be apparent, I am a clinical psychiatrist who also has a fundamental interest in animal behavior, especially primate social behavior. I entered the field from a clinical research standpoint to devel­ op some animal models of depression after being stimulated to do so by Dr. William Bunney, then at the National Institute of Mental Health and now at the University of California-Irvine. The field has grown rapidly since then and there is considerable research activity. Indeed, the re­ search activity has grown more rapidly than our conceptualization of what animal models are and are not. Animal preparations are now available for studying specific aspects of certain types of psychopathology. Thoughtful workers in the animal modeling field no longer talk about comprehensive models but rather about more limited experimental preparations in animals for studying certain specific aspects of human psychopathology.

Models of Seizures and Epilepsy

by Asla Pitkänen, Philip A. Schwartzkroin, Solomon L. Moshé

An understanding of mechanisms underlying seizure disorders depends critically on the insights provided by model systems. In particular with the development of cellular, molecular, and genetic investigative tools, there has been an explosion of basic epilepsy research. Models of Seizures and Epilepsy brings together, for the first time in 30 years, an overview of the most widely-used models of seizures and epilepsy. Chapters cover a broad range of experimental approaches (from in vitro to whole animal preparations), a variety of epileptiform phenomenology (including burst discharges and seizures), and suggestions for model characterization and validation, such as electrographic, morphologic, pharmacologic, and behavioral features. Experts in the field provide not only technical reviews of these models but also conceptual critiques - commenting on the strengths and limitations of these models, their relationship to clinical phenomenology, and their value in developing a better understanding and treatments. Models of Seizures and Epilepsy is a valuable, practical reference for investigators who are searching for the most appropriate laboratory models for addressing key questions in the field. It also provides an important background for physicians, fellows, and students, offering insight into the potential for advances in epilepsy research. - The first comprehensive description of animal models of epilepsy since the early 1970's - Comprehensive analysis of "What the models model" to guide the selection of each model, and what specific questions it will answer - Elegant examples of the use of novel technologies that can be applied in experimental epilepsy research - World expert opinions on the clinical relevance of each model

The book is aimed first towards seniors and beginning graduate students in biomedical engineering, neurophysiology, optometry, and psychology, who will gain a broad understanding of quantitative analysis of the visual system. In addition, it has sufficient depth in each area to be useful as an updated reference and tutorial for graduate and post-doctoral students, as well as general vision scientists.

Models of Wave Memory (Lecture Notes in Morphogenesis)

by Serguey Kashchenko

This monograph examines in detail models of neural systems described by delay-differential equations. Each element of the medium (neuron) is an oscillator that generates, in standalone mode, short impulses also known as spikes. The book discusses models of synaptic interaction between neurons, which lead to complex oscillatory modes in the system. In addition, it presents a solution to the problem of choosing the parameters of interaction in order to obtain attractors with predetermined structure. These attractors are represented as images encoded in the form of autowaves (wave memory). The target audience primarily comprises researchers and experts in the field, but it will also be beneficial for graduate students.

Moderate Sedation and Emergency Medicine for Periodontists

by Joseph A. Giovannitti Jr.

This book is intended for periodontal residents and practicing periodontists who wish to incorporate the principles of moderate sedation into daily practice. A history of the development of sedation in dental practice sets the stage for understanding the need for a comprehensive preanesthetic evaluation to identify potentially reactive patients prior to treatment. Useful drugs for moderate sedation and reversal agents in the office setting are reviewed to ensure proper perioperative usage. Comprehensive airway management and rescue skills are then documented in detail so that the patient may be properly managed in the event that the sedation progresses beyond the intended level. A key aim is to equip the reader with sufficient knowledge and preparedness to overcome the patient management challenges associated with common and uncommon deviations from intraoperative norms. Finally, for those academicians interested in teaching the principles of sedation to periodontal residents, a curriculum development tool is provided to ensure comprehensive training leading to competency.
