Abstract
This paper paper explores toxins and how they can affect the human body and looks at the benefits of drinking water. The paper talks about the increased exposure to toxins, some of the causes of this increase, where toxins come from, and the need for and process of detoxification. The paper also talks about the importance of drinking water and how it aids in the detoxification process. Included are a variety of charts and graphs about water.
From the Paper
"Humans today are finding their bodies barraged with many more substances than ever before. There is an increase in use of ?pesticides, additives and chemicals, as well as the amount of steroids, hormones and antibiotics fed to animals readied for human consumption (unknown, Toronto Star).? The number of ?smog alert? days during the summer continue to increase and there is concern about how safe chlorinated water really is. All of this provides proof that humans are eating, drinking and breathing more toxins than ever before."

Abstract
This paper presents an in-depth look at the water toxins and the way they affect the ecosystem as a whole. The writer takes the reader on an exploratory journey through the ecosystem and the way it works. Then it discusses the way water toxins and pollution are destroying the system by killing the marine organisms. Finally, it concludes that in the future it will be imperative to find ways to thwart the water toxins affects.
From the Paper
"Because we have lived on this planet for millions of years, we have come to rely on its ability to support and sustain human and animal life indefinitely. The world survives by way of an ecosystem and that system is the core of all living things. For many years now scientists have warned that our cavalier attitude toward preservation of the eco system will cause it to begin breaking down, however, their warnings often fell on deaf ears. Now it is time to pay the piper. Recently scientists have begun to take a close look at the cycles of life and the way they are intertwined in the ecosystem. There is strong evidence that toxins are destroying the ecosystem because the abundance and diversity of marine organisms is rapidly declining(Liat pp 142)."

Permanent Damage
Conclusion
From the Paper
"Further, it is important to realize that young children are still at a developmental stage. Their organ systems are still undergoing growth. In particular, their immune system and the nervous system are in the progress of development and at this stage any damage would seriously affect their cognitive development. The structural disorders that occur during this period may not be rectifiable because the nervous system is not sufficiently developed to recondition the affected pathways. Thus, environmental toxins can result in severe and permanent neurobehavioral dysfunctions. The child may be crippled with severe cognitive deficits, loss of intelligence and associated behavioral problems. Another important factor is that many of the toxic substances take years together to effect their damage. Examples include mesothelioma linked with asbestos, leukemia caused by benzene, Parkinson's disease caused by neurotoxins, etc. So naturally, children, because of their long life have increased risk of manifesting these degenerative diseases from their early exposure.

Click here to show/hide summary
Abstract
This paper analyzes Robin Cook's "Toxin", a work of fiction which addresses the very real public health issue of food safety, such as the diminished attention in American facilities to matters of sanitation, meat grade and facility quality. Likewise, the the book addresses the highly charged issue of the condition in American healthcare today, where the patient is all too often the loser in a scenario which treats hospital administration, insurance company and pharmaceutical firm as the primary stakeholders. The paper illustrates how, in "Toxin", Cook applies his knowledge as a formerly practicing physician to the task of identifying the duality of these above noted issues. The paper concludes that, as a discourse on public safety and healthcare, the Cook novel succeeds, but its failures as an emotionally compelling plot-based narrative may well neutralize these benefits. The paper is of the opinion that a more successful exploration of this subject might be yielded from an actual piece of journalism and not from one that masquerades as a fictional novel.
From the Paper
"That the Cook story centers on the death of a young woman of e-coli is important, particularly as it helps to dispel this above-mentioned false sense of security by sacrificing one of our young to industry carelessness. This device allows Cook to truly hammer home the incredible indifference and disregard by hospitals and food rendering plants alike that will provoke this death. Though at no point in the story are we inclined to like the girl as a person--as she is driven in life by a snotty and implacable sense of entitlement--in her death, we are nonetheless inclined to suggest that Cook's motives are distinct. That a child has been chosen as the primary victim in this story is compelling in its provocation of fear and discomfort in the reader. That one so vulnerable as a child might be treated with so little protection against the threats in question is illustrative of the story's point, which seems to be that in both of the industries here discussed, there is a shocking absence of humanity."

Biology Review, 2006.
A discussion regarding the role of antibodies and antigen in protecting the body's cells.
675 words (approx. 2.7 pages), 0 sources, $ 26.95
»
Click here to show/hide summary
Abstract
This paper discusses how antibodies and antigen serve to coat a foreign cell preventing the foreign cell from binding to other cells in the body. Binding of the antibodies and antigen to a toxin molecule prevents the foreign cell from accomplishing any of the tasks that it is intended to achieve. The paper further discusses how, never the less, this process is dependent on an effector mechanism in the complement system which has specific purposes. The compliment system serves as the overall protector while the antibodies and antigen direct the response of the compliment system which in turn destroys the foreign cells.
From the Paper
"The integrity of the plasma membrane is essential for cellular survival. Could the immune system utilize this fact to destroy foreign cells that have invaded the body? How might cells of the immune system disrupt membranes of foreign cells? (Two hints: virtually all cells can secrete proteins, and some proteins form pores in membranes.) Antibodies and antigen serve to coat a foreign cell, preventing the foreign cell from binding to other cells in the body. Binding of the antibodies and antigen to a toxin molecule prevents the foreign cell from accomplishing any of the tasks that it is intended to achieve. Yet, this process is dependent on an effector mechanism in the complement system, which has specific purposes. The compliment system serves as the overall protector, while the antibodies and antigen direct the response of the compliment system, which in turn destroys the foreign cells."

Epithelial Cells of the Nephron, 2008.
This paper describes the epithelial cells of the nephron, which is the basic structural and functional unit of the kidney.

Abstract
This paper explains that the framework of the nephron in the kidney is made up of epithelial cells. The author points out that there are two types of nephrons, cortical and juxtamedullary, and they are named according to the location within the renal parenchyma. The paper relates that epithelial cells that make up the nephron must be able to preserve nutrients and materials required by the body and return them to circulation, while leaving wastes, toxins and excess water to be expelled. The author states that the epithelia are described by the number of layers and the shape of the cells at the edge closest to the exterior environment, thus helping to prevent bacteria and other foreign materials from entering the body. The paper continues that the epithelial cells of the nephron permit the kidney to have particular functions that include controlling blood pressure.
From the Paper
"Epithelium lines the surfaces of the body and is positioned on the borders between the exterior and interior environments. Epithelium is a tissue composed of cells, bound tightly together with no intercellular connective tissue. These cells derive their food and oxygen from the tissue fluid that filters through from the capillaries in the underlying connective tissue. The epithelium develops in the embryo from all the three germ layers; ectoderm, mesoderm and endoderm. The epithelium is derived from mesenchyme cells that mature into connective tissue, bone, cartilage, blood and the lymphatic system."

From the Paper
" Ideally, a risk-free environment is one where all the technologies that are being utilized work together harmoniously, so that no pollution or danger to the public exists. However, creating a risk-free environment is a complex task. Too often efforts to resolve one environmental problem fail to consider the effects this solution will have on other environmental risks. For example, although the industrial release of toxins into the U.S. environment fell in 1992 for the fifth straight year, waste generation rose slightly.. Furthermore, while scientists are working on a fuel cell power supply that could power the cares of the 21st century--which would use hydrogen and oxygen to produce electric power with less pollution than other fuels.--a recent Environmental Protection Agency (EPA) report raises the possibility that the so-called "zero emission," or electric.."

»

Abstract
This paper presents the physiological symptoms that occur to pregnant women who suffer from morning sickness. The paper analyzes research on this topic carried out by M. Profet in "Pregnancy Sickness as Adaptation," which suggests that pregnancy sickness represents a lowering of the usual human threshold of tolerance to toxins in order to compensate for the extreme vulnerability of the embryo to toxins during organogenesis, the period of maximum susceptibility to toxins.
From the Paper
"Pregnancy sickness is commonly referred to as morning sickness. It is often defined as a set of symptoms that occur in some women during the first trimester of pregnancy. Women with pregnancy sickness may experience food aversions, nausea, and vomiting (Profet, 1992). Profet argued that these symptoms of pregnancy evolved during the course of human evolution to protect the embryo against maternal ingestion of toxins abundant in natural foods. She suggested that pregnancy sickness represents a lowering of the usual human threshold of tolerance to toxins in order to compensate for the extreme vulnerability of the embryo to toxins during organogenesis, the period of maximum susceptibility to toxins."

Global Warming and Rising Ocean Levels, 2005.
A combined research and ethics paper that examines the negative effects of global warming and their contribution to the rising ocean levels.
1,167 words (approx. 4.7 pages), 3 sources, MLA, $ 40.95
»
Click here to show/hide summary
Abstract
This paper presents facts about global warming and the effect it has, and will have, on the oceans and the delicate marine life and habitat. The discussion involves the melting of polar caps and the effects resulting from such devastation. The paper examines how warmer temperatures will destroy marine life and concentrates on the delicate coral reef system which is already feeling the effects of the warmer ocean temperatures. The temperature rise and ocean rise are discussed, along with ideas on halting the progression of dangerous toxins contributing to higher climate temperatures.
From the Paper
"As the coral reefs die, so do many other species of fish, crab and several other species. Large increases in the volumes of greenhouse gases in the atmosphere are already apparent. At current rates of change, carbon dioxide concentration in the atmosphere will double by the end of the next century (2100 AD). Calculations indicate that this rate of change in carbon dioxide alone will may result in a warming of between 1.5 and 4.5?C. The most likely effect of sustained global warming will be a melting of the polar ice caps, and a rise in sea level, while on land the deserts will expand."

Click here to show/hide summary
Abstract
The CYP2D protein in the human brain is expressed as CYP2D6 in liver and is known to metabolize a variety of drugs such as psychoactive, antihypertensives, and environmental toxins. Every person has a unique rate of metabolism. Metabolic rates in children are particularly susceptible to environmental toxicants which affect the way in which their systems absorb, distribute, metabolize and excrete chemicals. To date, knowledge in characterization of CYP proteins has been limited to immunoblotting, RT-PCR, immunohistochemistry and so forth; therefore, this paper investigates:
1) What kind of CYP2D protein is present in brain with modern proteomic tools;
2) Whether, CYP2D6 is the same as liver CYP2D6; and
3) If CYP2D7 is present, can CYP2D6 polymorphism be found in the brain?
To answer these questions, this study uses a one-step method of isolation of protein by immunoprecipitation followed by its identification using 2D-blots, nanospray LCMS, immunoblots and immunohistochemistry.

From the Paper
"The most promising area of pharmacogenetic research today may be in providing patients with customized treatments for specific cancer types. For instance, Christensen points out that Herceptin and Gleevec are two drugs that affect only cancerous tissues expressing certain genes. In the case of Herceptin, it binds to a protein that stimulates rapid tumor growth; this substance has been found to be present in excess in approximately 33 percent of breast cancers. Prior to prescribing the drug to their patients, doctors can now test how many copies of the gene for HER2/neu, which encodes this protein, are present or measure concentrations of the protein itself. Patients who do not have the excess HER2/neu protein or its gene would therefore not receive the drug. Gleevec takes advantage of a particular enzyme that is mutated in a few rare cancers, such as chronic myeloid leukemia. When Gleevec blocks the mutated enzyme, growth of the cancer cells stops; however, the drug has minimal effects on healthy dividing cells (Christensen, 2002)."

"The questions asked in this research will include the questions of: (1) How many deaths occur each year that are directly linked to exposure of the firefighter to some toxin that results in a health problem such as cancer? (2) How many firefighters have been fatalities in the last 10 years that were incorrectly labeled as a fatality? (3) What guidelines should be set out for future reliable statistics in firefighter fatality reports? And (4) What special precautions should be required under safety requirements in order to best protect firefighters from this type of exposure resulting in fatality?"

Abstract
This paper discusses bioterrorism and the dangers it brings to living organisms. It examines the history of bioterrorism from ancient times to the twentieth century and explains that it wasn't until the 1930s that the real science of bioterrorism really began to blossom. The writer looks at the research done on biological warfare, with special reference to the anthrax and botulinum toxins. The writer also believes that the technical community has the greatest challenge in developing biological agent detection both for the battlefield, and for civilian use. The writer concludes that the more we search for answers to counter the effects of bioterrorism the worse is gets.
From the Paper
"Throughout history, warriors and terrorists have used a wide range of tactics and
techniques to help defeat their enemy on and off the battlefield. These weapons of war
have evolved from throwing rocks and sticks at each other to the unthinkable weapons of
mass destruction called bioterrorism. You may ask yourself, what is bioterrorism? The
Center for Disease Control defines bioterrorism as the intentional or threatened use of bacteria, fungi, or toxins from living organisms to produce death or disease in humans, animals, or plants and involves intimidation of nations or people to accomplish political or social ends. (CDC 2005) In ancient times, archers shot arrows at their enemies that were dipped in blood from dead and decomposing bodies, while others had the feces of animals smeared onto the tips to cause severe infection after entering the body."

Abstract
In this article, the writer notes that today, breast cancer remains the focus of a growing amount of research around the world and new, improved diagnostic techniques, drugs and treatment are constantly improving survival rates. Nevertheless, the writer points out that the incidence of female breast cancer remains unacceptably high in many regions of the country, especially New Jersey. To identify recent trends in the incidence of female breast cancer generally and in New Jersey specifically, this paper provides a review of the relevant peer-reviewed literature and an analysis of the statistical rates by race for the state and its counties. A summary of the research and salient findings are presented in the conclusion. The writer concludes that the the research is clear in showing that virtually every county in New Jersey is considered high-risk for increased rates of breast cancer by virtue of their geographic proximity to nuclear reactors, as well as the potential environmental toxins that go hand in hand with high concentrations of humanity.

Conclusion
From the Paper
"Other environmental factors may relate to socioeconomic conditions. While the National Cancer Institute and other medical organizations agree that women age 50 years and older should obtain a routine mammography every one to two years, estimates of breast cancer screening utilization show that participation in mammography screening is typically lowest among groups of women with whom social workers often work; that is, older, low-income, rural, and racially and culturally diverse women. Studies have investigated a variety of factors predictive of women's decisions about breast cancer screening, including socioeconomic factors, and to a lesser extent, psychological and cultural variables; the results of these studies generally indicate that older and ethnic minority women, women with inadequate insurance coverage and no regular source of medical care, women that are less educated, women that live in medically underserved areas, and women that report strong religious values, attitudes, and beliefs about breast cancer, are less likely to obtain breast cancer screening and are at greater risk of dying from breast cancer than are white women who are younger, educated, have health insurance and access to medical care, and that do not express strong beliefs about breast cancer."

"The U. S. Commission on Ocean Policy reports that more than 28 million gallons of oil from human activities enter North American waters annually, but, according to an article in Issues in Science and Technology, "the bulk of human-related inputs is not due to large-scale spills and accidents that occur during the transport of crude oil or petroleum products" (Rabalais, 2003). In fact, researchers looking for sources of oil that runs into America's oceans can look into the "chronic low-level releases" of oil that add up to "roughly 16 million gallons of oil" annually, running down rivers and streams, according to the Rabalais article.
These oil pollutants "are most obvious in the watersheds that drain heavily populated areas," and the data from the U.S. Commission on Ocean Policy, plus the Sverdrup textbook, indicate that coast areas are becoming more and more heavily populated. Some of the 16 million gallons draining originates with "jettisoned aircraft fuel, marine recreational vehicles, and operational discharges, such as cargo washings and releases from petroleum extraction."
