...own words that support prenatal diagnosis for parents with no intention to abort HD‐positive fetus and three (3) points that are against it. Support 1) The possibility of a negative diagnosis represents a chance to be spared a long period of uncertainty about a child's health prospects and to spare the child from the same uncertainty in future years. Uncertainty about genetic status can be associated with anxiety and frustration. 2) Parents may use this information to decide whether to have more children in the future 3) Even if it were true that termination of pregnancy was the only appropriate reason to undergo testing, this would not justify withholding testing from parents who doubted that they would consider termination. There is no way of ensuring that those who say they will terminate their pregnancy after a positive test result will do so. Even if guidelines recommend that prenatal tests should be provided only when termination of pregnancy is planned in the event of a positive test result, there is no guarantee that those who say they will terminate their pregnancy after the positive test result will do so. If prenatal testing is only provided to those who would terminate their pregnancy in the event of a positive result, couples who do not have the intention to terminate their pregnancy could resort to lying Against 1) Individuals should be able to make an autonomous decision about whether or not to have predictive testing at a time when they are...

...Genetic testing is a scientific process in which an individual’s DNA can be screened for mutations or variations that may cause certain diseases or dysfunctions. It is my opinion that standard genetic testing for disease or the predisposition to disease is purely beneficial. Having clear answers as to whether or not a person may carry a higher risk for some diseases may in fact save their life, or the lives of their current or future children. However, over the years of development of the science, more and more controversial types of testing have developed. In this paper, the science of genetic testing will be introduced by going through a brief history, the different types of genetic testing available, as well as the controversies that surround them. History Genetic testing had a very positive and productive start. The first usage of Genetic Testing occurred over half a century ago, beginning with the testing of infants for PKU, or Phenylketonuria, “an inborn error of metabolism in which an amino acid buildup in the blood causes mental retardation.” (Lewis) To test infants, a drop of blood was taken from their heel while at the hospital after birth. If a child was found positive for PKU, dietary treatment was used to prevent loss of brain function. Testing was reliable and results were accurate. The disease being tested for was easily treatable, and every child that came through was tested without a problem. (Lewis) In the 1970’s, doctors began the process of testing...

...a good job, a loving spouse, maybe a couple of kids and an all-around pretty good life. Then imagine one day your boss writes you up and sends you home because he/she suspects you of being intoxicated. A person in this situation could, in months and years to come, learn from a simple blood test that he/she is the victim of a genetic disorder called Huntington’s disease. The ramifications of this illness are endless and affect not only the individual with the disorder but entire families and communities as well. At this time there is no cure or even any significantly effective treatment. However, as with many genetic disorders, research is being done in in this day in age that may promise to one day lead us to such treatment or cure. Huntington’s disease is a neurodegenerative or genetic disorder that affects muscle coordination and some cognitive functions, typically becoming noticeable in middle age. It is much more common in people of Western Europe descent than in those from Asia or Africa. The disease is caused by dominant mutation on either of the two copies of a specific gene, located on chromosome 4. The Huntington gene normally provides the genetic code for a protein that is also called Huntingtin. The mutation of the Huntingtin gene codes for a different form of the protein, whose presence results in gradual damage to specific areas of the brain. The condition Huntington’s disease got its name because it was first described by George Huntington, a physician in New York...

...immunology, and development of pharmaceutical therapies and diagnostic tests.[3] Definitions of biotechnology The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. Biotechnology is defined by the American Chemical Society as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms such as pharmaceuticals, crops, and livestock.[4] In other words, biotechnology can be defined as the mere application of technical advances in life science to develop commercial products. Biotechnology also writes on the pure biological sciences (genetics, microbiology, animal cell...

...Chapter 1 Introduction to Pathophysiology Lee-Ellen C. Copstead Key Questions • What is pathophysiology? • How are etiology and pathogenesis used to predict clinical manifestations and response to therapy? • How are normal and abnormal physiologic parameters defined? • What general factors affect the expression of disease in a particular person? • What kinds of information about disease can be gained through understanding concepts of epidemiology? http://evolve.elsevier.com/Copstead/ • Review Questions and Answers • Glossary (with audio pronunciations for selected terms) • Animations • Case Studies • Key Points Review Pathophysiology derives from the intersection of two older, related disciplines: pathology (from pathos, suffering) and physiology (from physis, nature). Pathology is the study and diagnosis of disease through examination of organs, tissues, cells, and bodily fluids. Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Together, as pathophysiology, the term refers to the study of abnormalities in physiologic functioning of living beings. Pathophysiology seeks to reveal physiologic responses of an organism to disruptions in its internal or external environment. Because humans exhibit considerable diversity, healthy structure and function are not precisely the same in any two individuals. However, discovering the common and expected responses to abnormalities in physiologic functioning is useful, and it...

She had been admitted to hospital on nine occasions due to continuous crying, believed to be caused by pain.2 Comparable stories about severely handicapped children can be found in several other countries as well. Both Brian and Kelly were not supposed to have been born in the sense that their mothers would have chosen for an abortion had they known in time about the birth defects their children would suffer. Brian’s mother would have undergone a termination of her pregnancy had the obstetrician and gynaecologist she consulted detected any abnormalities in the foetus and advised her thereof. Kelly’s mother had asked the obstetrician she consulted to carry out some tests regarding possible hereditary diseases and genetic defects, because she had decided to terminate the pregnancy if the tests on the foetus would show severe disabilities. She did so because there was a history of chromosome defects in her husband’s family and she herself had already suffered two miscarriages previously. * Ivo Giesen is Professor of Private Law and Civil Procedure...

...philosophy) involves systematizing, defending, and recommending concepts of right and wrong behavior. Philosophers today usually divide ethical theories into three general subject areas: metaethics, normative ethics, and applied ethics. Metaethics investigates where our ethical principles come from, and what they mean. Are they merely social inventions? Do they involve more than expressions of our individual emotions? Metaethical answers to these questions focus on the issues of universal truths, the will of God, the role of reason in ethical judgments, and the meaning of ethical terms themselves. Normative ethics takes on a more practical task, which is to arrive at moral standards that regulate right and wrong conduct. This may involve articulating the good habits that we should acquire, the duties that we should follow, or the consequences of our behavior on others. Finally, applied ethics involves examining specific controversial issues, such as abortion, infanticide, animal rights, environmental concerns, homosexuality, capital punishment, or nuclear war. By using the conceptual tools of metaethics and normative ethics, discussions in applied ethics try to resolve these controversial issues. The lines of distinction between metaethics, normative ethics, and applied ethics are often blurry. For example, the issue of abortion is an applied ethical topic since it involves a specific type of controversial behavior. But it also depends on more general normative principles, such as...

...begin with an overview of how diverse social science and life science researchers (collectively known as developmentalists) approach the monumental task of studying humans over the course of the life span. Our discussion includes the goals of the scientific community, the recognized framework for studying the life span, what aspects of development warrant extensive examination, and what scientific methods are used to conduct research with humans. Chapter 2 discusses the main developmental theories over the past 100 years, when social scientists, biologists, and chemists focused on studying discrete aspects of human development. Earlier introspective methods about subconscious experience and contemporary measurable evidence about microscopic genetic codes, neurons, and hormones all contribute to our understanding of the human condition. Contemporary researchers are focusing on how to integrate scientific findings and theory from across cultures into a more meaningful whole about human development. CHAPTER 1 Introduction Critical Thinking Questions 1. Developmental change takes place in three fundamental domains: physical, cognitive, and emotional-social. Which domain has been most important for your becoming who you are? Will any one of the domains become more important as you get older? 2. Make a list of three aspects of yourself that have changed over the last 10 years and three that have remained constant. How do you feel about both the “dynamic” and the “static” aspects...

...TPS 101: INTRODUCTION TO PSYCHOLOGY TPS 101 serves as the beginning course in psychology; as such, it is broad in scope. The course will introduce students to the history of psychology, and current paradigms and theories. We will cover neuroscience, sensation, perception, memory, and language, stress and health psychology, personality and social psychology, intelligence, and developmental psychology. Because of time limitations, none of these topics can be covered in great depth. The reference textbooks and the material presented in class will serve as the primary sources for the material to be covered. INTRODUCTION TO THE STUDY OF PSYCHOLOGY Psychology is the scientific study of behaviour and mental processes. It is an academic and applied discipline involving the scientific study of mental processes and behaviour. Psychology also refers to the application of such knowledge to various spheres of human activity, including problems of individuals' daily lives and the treatment of mental illness. It is largely concerned with humans, although the behaviour and mental processes of animals can also be part of psychology research, either as a subject in its own right (e.g. animal cognition and ethnology), or somewhat more controversially, as a way of gaining an insight into human psychology by means of comparison (including comparative psychology). Origins of the psychology Near the end of 19th century things started drawing together. Questions raised by philosophers were being...

Basic Theoretical Issues Issue 1: Is Development Active or Reactive? Issue 2: Is Development Continuous or Discontinuous? Theoretical Perspectives * Theories are never “set in stone”; they are always open to change as a result of new findings? * Children shape their world as it shapes them? * Cross-cultural research enables us to determine which aspects of development are universal and which are culturally influenced? * An experiment is the most definitive way to demonstrate that one event causes another? * The results of laboratory experiments may be less applicable to real life than experiments carried out in a home, school, or public setting? These are just a few of the interesting and important topics we will cover in this chapter. Here, we present an overview both of major theories of human development and of research methods used to study it. In the first part of the chapter, we explore major issues and theoretical perspectives that...

...now b. Ideal – what we are aiming at 3. Human beings are self – conscious. This means we can study ourselves by being a subject and be the object at the same time. 4. Human beings are finite or limited not knowing what will happen from the next moment or next door. Thus, we must have principles to apply when situations comes. 5. Human life is an active dynamic phenomenon – We do something as if we do nothing. 6. People also can be taught to be good (Isaiah 1 :18) 7. Human beings are capable of filing an obligation 8. Human beings are also capable of understanding what moral terms like freedom, dignity and so on affects other people. 9. Finally, human beings need to survive. Human civilization, therefore, can not survive without ethical people. History of Ethics Outside Christianity, some people have taught about ethics. Amongst those who taught ethics are: 1. Socrates 457 BC, a Greek philosopher whose key question was, “What is the meaning of Life”? Socrates like every life seeker was concerned about the good life. Socrates said, “The unexamined life is not worthy...
