...Cystic Fibrosis By Cameron Boulden Cameron Boulden BI101NB Cellular Essay Cystic Fibrosis Cystic Fibrosis is a genetic disorder passed down to children from parents through defective genes. Normally neither parent has the disease, it is the child who inherits one damaged gene from each parent, causing the infection. Some of the target areas for cystic fibrosis are, sex organs, lungs, liver, pancreas, and sinus. (Gary H. Gibbons) People living with cystic fibrosis have thick gluey mucus that builds up in their lungs and blocks the airways, ultimately making it hard for tubes to carry air in and out. Typically mucus is watery, keeping organs moisturized so they don’t dry out. (Gary H. Gibbons) Mutation of the CFTR (cystic fibrosis transmembrane conductance regulator) gene is what leads to cystic fibrosis. A change in this gene negatively affects the formation of the CFTR protein, making it unable to pass chloride ions and water in and out of cells. The lungs and pancreas are then directly...

...Running Head: UNIT THREE WRITTEN ASSIGNMENTS Unit Three Written Assignments Erin Schmidt Professor Vega St. Joseph’s College of Maine Prepared on November 30, 2009 1. Of all the people using the health care system today, how important are social problems on the use of the health care system? Social problems including AIDS, drug abuse, violence, and teen pregnancy are very important when considering the economy of the United States Health Care System. Unprotected sexual contact and sharing dirty needles account for the majority of persons infected with AIDS. HIV and AIDS affect human capitol due to the increased mortality of this group. Bonnel (2000) notes that younger individuals are dying of this disease, which translates to a decreased taxable population and reduction in resources for public expenditures. Medications such as antiretrovirals are very expensive. Henderson (2002) points out that drug therapy costs up to $16,000 dollars per infected individual per year. Additional economic impact can be thought of in terms of lost productivity, and lost days from work, which account for a significant impact on the labor supply. With regard to substance abuse, Henderson (2002) states “substance abuse is the leading health problem in the United States today” (p. 310). Costs associated with substance abuse include increased costs of medical care, lost productivity from...

Death is unavoidable, yet the situation becomes evermore helpless when it strikes the young; the innocent who have not had their share of time, as is the case with a condition like Tay-Sachs disease. Fortunately, much childhood disease that plagued us for centuries has been eradicated due to the advances of modern science, and with the prospects of genetic technology today, the future is looking promising for those that have manage to elude scientists, like Tay-Sachs. However, Tay-Sachs is not a disease that can be considered in terms of science alone; it effects a unique ethnic population whose history and beliefs need to be considered in a sensitive manner. Tay-Sachs disease is a genetic disorder that is devastating in its deadliness. This rare fatal disease is passed down through families. The disease’s hyphenated name is the result of two doctors, who worked independently of one another in the late 1800s. Dr. Warren Tay, an ophthalmologist, was the first to characterize one of the tell tale signs of the disease, the retina of the eye has a cherry red spot. A New York, neurologist, Dr. Bernard Sachs provided the first description of the biological mutations with Tay-Sachs disease. Tay-Sachs is a progressive neurodegenerative disorders. The individuals...

...Modified Animals Animals with special characteristics and traits have been cross breed through sexual reproduction for many years, but with the increasing of technology, scientists can now create animals directly from gene modification. Genetic modification is described as the science used to change the characteristics of an organism genetic component and manipulate the deoxyribonucleic acid structures using technology. “Deoxyribonucleic acid (DNA) is nucleic acid that carries hereditary information about traits of an organism and carries the instructions for all the characteristics that organism inherits, it consist of two chain of nucleotides twisted into a double helix” (Starr, C., Evers, C. A., Starr, L. 2013). Genetically modified animals are made from embryonic stem cells carrying two copies of gene one from the male and the other from the female. Scientists cut and join DNA from different sources then transfer it into the organism so it has the modified genes and from that procedure, a new set of genes is created. Manipulating the DNA and transforming certain gene to create a new life is called recombinant DNA (rDNA) technique. Scientists use recombinant DNA technique to modify the chemical inside the nucleus of a cell which carries genetic instructions from one organism to another and to improve specific characteristics of an animal or to introduce a new trait that is resistant to diseases and may enhance the growth of animals. In addition, the changes introduced to that...

...recessive, genetic illness, which affects the work of lungs, liver, intestine, and pancreas. This disease causes malfunctioning of the chloride and sodium transportation across the body and results in the thick and viscous secretions. Nowadays, cystic fibrosis affects thousands of people, especially in Europe and the US. Although, cystic fibrosis is a rare disease, it is quickly spreading all over the world and leads to the general shortage of life. In fact, it is a serious disease, which calls for an immediate diagnosis and appropriate treatment. History of the Disease Cystic fibrosis was discovered in the first half of the 20th century. However, without doubts, it emerged thousands of years before. The researchers surmise that cystic fibrosis appeared about 3000 BC, as a result of migration and gene mutation. During the 16-17th centuries, the salty taste of the skin (which is the symptom of cystic fibrosis) was considered a sign of bewitchment. Dr. Dorothy Andersen was the very first to describe the peculiarities and main characteristics of this disease. Before that investigation, the humanity had already known some facts and elements of cystic fibrosis. The reason for such late examination of this disease can be explained with the lack of required tools and means. Even nowadays, there are still many researches, aiming at providing objective information about cystic fibrosis and applying to the methods of the newborn and antenatal screening and carrier testing. In 1985...

...many examinations of birth order and the effect it has on a person’s intelligence. Some researchers feel that first-born children have higher IQ’s than that of their younger siblings. It has been said that first-born children are natural leaders. Siblings of first-born children perceive them to be academically smarter. Eldest children are known to perform higher on standardize testing than younger children in the family. Other researchers have stated that family size/home life, age of mother and circumstances around the birth of each individual child determines where they are intellectually. Researchers need to look at every aspect of the child’s life before they decide which child is smarter. Intelligence and Birth Order: Are They Connected? Birth order is where a person ranks in regards to age among their siblings, from oldest to youngest and vice-versa. There is much debate on the relationship between a person birth order and how intelligent we are. Many studies have been done to determine if there is a link to the firstborn having a higher IQ in general compared to their siblings. Some people would agree that birth order has a profound influence over intelligence; however, others are in opposition to this. The opposition feels that birth order has no effect when it comes to intelligence. Does birth order cause children to have lower or higher intellect or is this caused by factors within the home? There have been many studies over the last century to explore...

...are derived from genetically modified organisms (GMOs). They differ from traditional foods in that their DNA have been introduced to genetic engineering techniques to enhance desired traits such as improved nutritional content and much more. Over 40 plant varieties have federal requirements for commercialization as GMOs. It all started in 1946, when scientists discovered DNA transfer between organisms. The first genetically modified plant was produced in 1983 and now 165 million acres annually are grown. However, along with rapid adoption of technology have come myths propagated by proponents and opponents. Different GM organisms include different genes inserted in different ways. All GM foods currently available on the international market have passed risk assessments and are not likely to present risks for human health. The general population has showed no effects on human health because of the consumption of such foods. Continuous use of risk assessments based on the Codex principles and, where appropriate, including post market monitoring, should form the basis for evaluating the safety of GM foods. (Winter & Gallegos, 2006) The GM foods controversy is a dispute over the relative advantages and disadvantages of food derived from GMOs, GM crops used and other uses of GMOs in food production. The world population has topped 6 billion people and is predicted to double in the next 50 years thus ensuring an adequate food supply for this booming population is going to be a major...

...To appear in: Oxford Companion to the Affective Sciences Oxford University Press Personality and Emotion William Revelle Department of Psychology Northwestern University Klaus R. Scherer Swiss Center for Affective Sciences University of Geneva Personality is the coherent patterning of affect, behavior, cognition, and desires (goals) over time and space. Just as a full blown emotion represents an integration of feeling, action, appraisal and wants at a particular time and location so does personality represent integration over time and space of these components (Ortony et al., 2005). A helpful analogy is to consider that personality is to emotion as climate is to weather. That is, what one expects is personality, what one observes at any particular moment is emotion. To understand the personality-affect link it is necessary to consider the ways in which personality may be described. Since Theophrastus’ discussion of characters and Galen’s theory of temperament (Stelmack & Stalikas, 1991), dimensional models of individual differences in personality have consistently identified three (the Giant Three, e.g., Eysenck & Eysenck (1985)) to five (the Big Five, e.g., Digman (1990)) broad dimensions of personality. Two of these dimensions, in particular, Extraversion (E) and Neuroticism (N, sometimes referred to by the other end of the dimension as Emotional Stability) have been associated with individual differences in affective level and environmental responsivity (Corr, 2008;...

...Genetic Engineering is Not the Answer to Hunger Rachel Salters Genetic Engineering is Not the Answer to Hunger In the past ten years, the world has seen many changes and advances, but none hold as many possibilities as genetic engineering. Genetic engineering is turning up all over, and it is definitely here to stay. Just as computers and plastics changed most aspects of living, since they were invented, biological engineering has the potential to do the same in the future. This new technology has a wide range of possible benefits, from helping farmers and sick people, to improving foods and helping the environment. Genetic engineering may even one day be used to help solve world hunger. Genetically engineered crops might seem an ideal solution. Yet both current data and past examples show problems and provoke doubts as to their necessity.There is no simple solution to end world hunger. Genetic engineering is not the answer, just as pesticides weren't the answer. Even increasing food production is not the answer. World hunger will only end when the underlying causes of poverty are addressed. Poverty stops people from obtaining their basic right to food - either because they have no means to purchase food or they have no access to the farmland and natural resources necessary to meet basic food needs (http://www1.umn.edu/humanrts/edumat/IHRIP/circle/modules/module12.htm). Genetically engineering crops do not address the poverty that causes hunger – in fact it threatens...

Biologic drugs and products are more complex than most pharmaceutical drugs. Pharmaceutical drugs are typically produced by chemical synthesis, meaning specific reagents can be processed by chemical reactions to yield the same product every time. In contrast, biologic drugs are made by the genetic engineering of an organism’s cellular mechanisms to create the desired product. Being biologic means that the drugs are manufactured using living organisms rather than by chemical reactions. Biologic drugs are very large, complex proteins. Because of natural variability in living cells, uncontrollable small differences are inevitable in both the biological manufacturing processes and the resulting molecules. The biotechnology industry is a profitable industry; it is worth $200b and is growing 11% YoY. The industry spending is expected to grow to $210b in 2016...

...Western industrialized nations, with substantial health disparities being observed across population subgroups and geographic regions.” (Hazel D. Dean, ScD, MPH Kevin A. Fenton, MD, PhD, 2010) This paper will focus specifically on HIV/AIDS. “ Genetic research indicates that HIV originated in west-central Africa during the late nineteenth or early twentieth century. · AIDS was first recognized by the U.S. Centers for Disease Control and Prevention in 1981 and its cause, HIV, identified in the early 1980s. ("STOP AIDS," 2009) Acquired Immune Deficiency Syndrome(AIDS) is a disease caused by the Human Immunodeficiency Virus (HIV). HIV attacks the human immune system, and progressively reduces its effectiveness, leaving the host susceptible to opportunistic infections and tumors. Due to the extended incubation period, the time between being infected with the virus and the manifestation of symptoms, an infected individual can transmit these the virus to other hosts unknowingly. The period between infection and the appearance of AIDS can take from 7 to 12 years, resulting in AIDS having reached pandemic proportions. The first cases were reported in 1981 and in 2007 it was estimated that more than 33 million people worldwide suffered from the disease and over 2 million...

...How Genetically Modified Foods Affect Our Lives In recent years, genetically modified organisms (GMOs) have replaced our diet with genetically altered foods, which have adversely affected human health as well as local communities. Being resistant to pesticides, GMOs are created by splicing genes of different species that are combined through genetic engineering (GE), something that is impossible to do in nature (The Non-GMO Project). Consuming these genetically altered and more processed foods can lead to increased risk of diseases and even cancer (Genetically Modified Food). Most of the time we do not even realize that we are eating these harmful toxins as they are infused in our food without our knowledge (Label GMOs). The farmers that maintain the traditional farming practices and choose to grow organic produce over crops that are GE are constantly trying to keep their businesses alive. Larger corporations, however, who choose to use genetically modified (GM) seeds, make larger profits with less time and effort involved. Choosing to buy local organic produce over crops that contain genetically modified organisms can not only help you stay healthy, but also keep our local farmers in business so that they may continue to grow their crops the way nature intended. Living in the Bay Area we are extremely fortunate to have access to all sorts of organic fruits and vegetables that are grown right in our own backyard.
