Affect as Contamination
Bringing the concept of contamination into dialogue with affect theory and bioart, Agnieszka Wolodzko urges us to rethink our relationship with ourselves, each other and other organisms. Thinking through the lens of contamination, this book provides an innovative approach to understanding the leaky, porous and visceral nature of our bodies and their endless interrelationships and, in doing so, uncovers new ways for thinking about embodiment. Affect theory has long been interested in transmission or contagion but, inspired by Spinoza and Deleuze, Affect as Contamination goes further, as contamination is concerned with the materiality of bodies and their affective encounter with other matter. This brings urgency to the notion of affect, not only for bioart that works with risky bodies but also for understanding how to practise our bodies in the age of biotechnological manipulation and governance. Using challenging and transgressive bioart projects as provocative case studies for rethinking affect and bodily practice, Wolodzko follows various 'contaminants' from blood, hormones and viruses to food, glitter and plants. This takes the form of both personal accounts of encounters with the contaminations of bioart and critical analyses of aesthetic, material and technical objects, with each one highlighting in different ways the risky and uncertain nature of contamination. Affect as Contamination is an urgent and original meditation on just what it means to be living, and practising our bodies, in an era where biotechnology contaminates all aspects of our lives.
Dissemination and Implementation Research in Health
The ultimate guide to dissemination and implementation research for public health, medicine, and the social sciencesIn the past twenty years, dissemination and implementation (D&I) research has sought to narrow the gap between the discovery of new knowledge and its application in public health, mental health, and health care settings. The challenges of moving research to practice and policy are universal, and future progress calls for collaborative partnerships and cross-country research. The fundamental tenet of D&I research-taking what we know about improving health and putting it into practice-must be the highest priority. Dissemination and Implementation Research in Health is the definitive roadmap to effecting change in health and science from today's leading D&I researchers. With insights from around the globe, these scholars collectively address key issues in the field including how to evaluate evidence based on effective interventions, how to design an appropriate study, and how to track a set of essential outcomes. Their work has been updated in this third edition with a strong focus on health equity and new chapters on de-implementation, scale-up and sustainment, and training and capacity building. This new edition also focuses on barriers to uptake of evidence-based interventions in the communities where people live their lives and from the social service agencies, hospitals, and clinics where they receive care. Now in its third edition, Dissemination and Implementation Research in Health remains the quintessential guide to making research more consequential for researchers and practitioners in health and the social sciences.
Guarding Against Pertussis. The Efficacy and Advantages of the TdaP Vaccine
Scientific Study from the year 2023 in the subject Medicine - Biomedical Engineering, grade: 3, language: English, abstract: This paper aims to elucidate the importance of TdaP vaccines in the prevention of pertussis, highlight the increased risk of this disease in adults, and underscore the benefits of using acellular vaccines over whole-cell vaccines. This text underscores the escalating threat of Pertussis (whooping cough) in adults and its lethal repercussions on infants with lesser immunity. This has led to innovations in vaccine development, particularly the emergence of acellular vaccines like the TdaP vaccine that effectively combats Tetanus, Diphtheria, and Pertussis. This vaccine offers the advantage of fewer side effects compared to whole-cell vaccines and contains purified antigenic components of Bordetella pertussis obtained through various purification techniques. The increased risk of pertussis in adults have become an important public-health issue. This contagious disease spreads to infants who have lesser immunity resulting in their death. Increased death rate caused the inventions of vaccinations to prevent this disease. Concerns regarding the safety of whole-cell vaccines used for pertussis treatment lead to the development of acellular pertussis vaccines like TdaP vaccines. This combination vaccine is 71-85% effective in the treatment of adults suffering from diseases tetanus, diphtheria and pertussis. These vaccines have limited side effects when compared to whole-cell vaccines as they contain purified antigenic components of Bordet Ella pertussis (Pertussis toxin, Filamentous hemagglutinin and Pertactin) that are obtained by the purification techniques Tangential flow filtration, Column Chromatography and Dialysis. These components are then formulated for purified vaccine production.

Case Illustrations and Discussions for Medical Students and Junior Residents
There are many standard text books of surgery covering variousaspects of surgery nd their sub-specialties. The purpose of this book is to assist students especially junior onces to acquire the necessary skills in history taken, physical examination, important investigations and the management of surgical patients. The methodology used was clinical history case demonstration and physical examination, summary of the important clinical investigations and their results, treatment offered and their outcome. Thereafter the aethopathology of the disease condition (where necessary), some modern investitagions and their likely outcome, current treatment options available, complications of the disease condition and their likely differential diagnosis were discussed in outline fashion. Repetations in some of the topics is deliberate and inevitable. This is to give the student deep and reflective insight into the disease conditions, their mode of presentation and possible current management options available. Some of the chapters have short vignettes which is meant to be brain teasers for both undergraduates and post graduate students preparing for the surgical medical exams such as objective structured clinical examination ((OSCE), medical viva, written examination and clinical examination. It is hoped to serve as a fast and focused revision guide to students of surgery and would be of immense assistance to students during ward round, ground-round and tutorials. It will improve their skill in case presentation, and in answering questions clearly, precisely and in unambiquous manner during their period of apprenticeship. It is therefore not a replacement for standard text books of surgery and will only be useful to those who have read through standard text books of surgery. Benjamin I Tabowei.

Computer-Aided Detection of Architectural Distortion in Prior Mammograms of Interval Cancer
Architectural distortion is an important and early sign of breast cancer, but because of its subtlety, it is a common cause of false-negative findings on screening mammograms. Screening mammograms obtained prior to the detection of cancer could contain subtle signs of early stages of breast cancer, in particular, architectural distortion. This book presents image processing and pattern recognition techniques to detect architectural distortion in prior mammograms of interval-cancer cases. The methods are based upon Gabor filters, phase portrait analysis, procedures for the analysis of the angular spread of power, fractal analysis, Laws' texture energy measures derived from geometrically transformed regions of interest (ROIs), and Haralick's texture features. With Gabor filters and phase-portrait analysis, 4,224 ROIs were automatically obtained from 106 prior mammograms of 56 interval-cancer cases, including 301 true-positive ROIs related to architectural distortion, and from 52 mammograms of 13 normal cases. For each ROI, the fractal dimension, the entropy of the angular spread of power, 10 Laws' texture energy measures, and Haralick's 14 texture features were computed. The areas under the receiver operating characteristic (ROC) curves obtained using the features selected by stepwise logistic regression and the leave-one-image-out method are 0.77 with the Bayesian classifier, 0.76 with Fisher linear discriminant analysis, and 0.79 with a neural network classifier. Free-response ROC analysis indicated sensitivities of 0.80 and 0.90 at 5.7 and 8.8 false positives (FPs) per image, respectively, with the Bayesian classifier and the leave-one-image-out method. The present study has demonstrated the ability to detect early signs of breast cancer 15 months ahead of the time of clinical diagnosis, on the average, for interval-cancer cases, with a sensitivity of 0.8 at 5.7 FP/image. The presented computer-aided detection techniques, dedicated to accurate detection and localization of architectural distortion, could lead to efficient detection of early and subtle signs of breast cancer at pre-mass-formation stages.

Basic Probability Theory for Biomedical Engineers
This is the first in a series of short books on probability theory and random processes for biomedical engineers. This text is written as an introduction to probability theory. The goal was to prepare students, engineers and scientists at all levels of background and experience for the application of this theory to a wide variety of problems--as well as pursue these topics at a more advanced level. The approach is to present a unified treatment of the subject. There are only a few key concepts involved in the basic theory of probability theory. These key concepts are all presented in the first chapter. The second chapter introduces the topic of random variables. Later chapters simply expand upon these key ideas and extend the range of application. A considerable effort has been made to develop the theory in a logical manner--developing special mathematical skills as needed. The mathematical background required of the reader is basic knowledge of differential calculus. Every effort has been made to be consistent with commonly used notation and terminology--both within the engineering community as well as the probability and statistics literature. Biomedical engineering examples are introduced throughout the text and a large number of self-study problems are available for the reader.

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 systemoscillate. This same approach was used to show how daily light/dark cycles could cascade rhythmic patterns throughout ecosystems and within organisms. Following up on these results, the author discusses how the twin requirements of internal synchronization (precise temporal order necessary for the proper functioning of organisms as complex, goal-oriented devices) and external synchronization (aligning organisms' behavior and physiology with geophysical cycles) supported the evolution of biological clocks. The author then investigates the clock systems that evolved using both conceptual and mathematical models, with the assistance of Dr. Bahrad Sokhansanj, who contributes a chapter on mathematical formulations and models of rhythmic phenomena. With the ubiquity of biological rhythms established, the author suggests a new classification system: the F4LM approach (Function; Frequency; waveForm; Flexibility; Level of biological system expressing rhythms; and Mode of rhythm generation) to investigate biological rhythms. This approach is first used on the more familiar cardiac cycle and then on neural rhythms as exemplified and measured by the electroencephalogram. During the process of investigating neural cycles, the author finds yet another reason for the evolution of biological rhythms: physical constraints, such as those imposed upon long distance neural signaling. In addition, a common theme emerges of a select number of autorhythmic biological oscillators imposing coherent rhythmicity on a larger network or system. During the course of the volume, the author uses a variety of observations, models, experimental results, and arguments to support the original claim of the importance and universality of biological rhythms. In Volume 2, the author will move from the establishment of the critical nature of biological rhythms to how these phenomena may be used to improve human health, well-being, and productivity. In a sense, Volume 1 focuses on the chronobio aspect of chronobioengineering while Volume 2 investigates methods of translating this knowledge into applications, the engineering aspect of chronobioengineering.

Single-Molecule Tools for Bioanalysis
In the last three decades, the fast development of single-molecule techniques has revolutionized the way we observe and understand biological processes. Some of these techniques have been further adapted as tools for bioanalysis. This book summarizes and details the frontiers of the development of these tools as well as their applications. The contributors are young and established researchers in their respective fields. The main content originates from the lecture notes of a chemistry graduate course taught by the book editor at Nanjing University. This book is suitable to be used as a textbook for a high-level undergraduate or an entry-level graduate course. The systematically written content provides a thorough illustration of the mechanisms of each methodology presented.
Implementation Science
This accessible textbook introduces a wide spectrum of ideas, approaches, and examples that make up the emerging field of implementation science, including implementation theory, processes and methods, data collection and analysis, brokering interest on the ground, and sustainable implementation. Containing over 60 concise essays, each addressing the thorny problem of how we can make care more evidence-informed, this book looks at how implementation science should be defined, how it can be conducted, and how it is assessed. It offers vital insight into how research findings that are derived from healthcare contexts can help make sense of service delivery and patient encounters. Each entry concentrates on an important concept and examines the idea's evidence base, root causes and effects, ideas and applications, and methodologies and methods. Revealing a very human side to caregiving, but also tackling its more complex and technological aspects, the contributors draw on real-life healthcare examples to look both at why things go right in introducing a new intervention and at what can go wrong. Implementation Science: The Key Concepts provides a toolbox of rich, contemporary thought from leading international thinkers, clearly and succinctly delivered. This comprehensive and enlightening range of ideas and examples brought together in one place is essential reading for all students, researchers, and practitioners with an interest in translating knowledge into practice in healthcare.
