Abstract
This paper discusses how Latin America has been struggling with some serious environmental concerns over the last two decades. Air and water pollution, pesticide abuse, soil degradation and deforestation are some of the pressing issues in this part of the world. Furthermore, this paper looks at the case of Argentina to see how the country, which has been struggling through an economic crisis, has seen the bitter end of an environmental catastrophe, and its efforts at redeeming the situation. The drastic effects of genetically modified crop cultivation (in particular GM Soya) and deforestation, the two most important environmental issues, are assessed in this essay.

From the Paper
"The FSC, developed after the Rio Digenero summit in 1992, focused on the increased global requirement and the depletion of natural resources. FSC is a non-profit organization that offers environmentally sound solutions for managing forests around the world. Asides playing an active supporting role in developing the national and regional forest management standards, the FSC also works with local certifiers to ensure FSC compliance standards are met. In Argentina, the FSC is playing an active monitoring role, and thus the rapid deforestation activities from the paper and other industries, which were thus far unchecked, would now be carefully monitored and assessed for their environmental impact. The Success of the FSC initiative can be attested by the fact that six plantation companies in the country namely Santa Barbara SRL, Faplac, Fiplasto, Forestal Las Marias, Lipsia, Tabepicua, and the Union Bank of Switzerland have become FSC certified bringing a total forest area of around 131,000 hectares under the FSC certification process."

Abstract
In this article, the writer provides a medical epidemiology and overview of contact dermatitis, while focusing on the risks and complications associated with contact dermatitis among workers in the construction industry. The writer pays attention to Irish laws in place meant to protect workers from exposure to irritants that may result in contact or allergic contact dermatitis. The purpose of this investigation is to determine the prevalence of contact dermatitis and looked at what actions may be necessary to mitigate risk or provide additional resources for those most at risk for contagion with this known disease.

Summary of Literature Review
From the Paper
"As more and more construction workers develop symptoms of allergic contact dermatitis, it is more important than ever that researchers focus on ways and methods they can prevent occupational hazards from reducing one's capacity to work or their quality of life. Among the important facts noted in the literature review is the increasing prevalence of contact dermatitis in Ireland and other areas where legislation has been slow to enforce some health and occupational acts that would protect workers from exposure to chemical irritants. Cited in this literature review are cases suggesting that Irish buildings and drinking water are among the primary causes for allergic or irritant contact dermatitis among workers and civilians alike. This serves to emphasize the need for a complete review of contact dermatitis, including its many forms, and an evaluation of the current legislation in place to assess its relevance and whether legislation needs to be improved to protect workers from developing debilitating forms of this condition."

Review Of Postprandial Studies And Effect On Plasma Polyphenols
From the Paper
"The diet is abundant in polyphenols, which are micronutrients. Furthermore there is a great deal of evidence, which exists to demonstrate the role polyphenols play in prevention of certain diseases and including cancer. (Manach et al 2004) The amount consumed and absorbed is the factor that determines the effects to health of polyphenols. In making determination of the absorption of polyphenols following food intake there are two studies that are differential in nature and which are conducted on the basis of both direct and indirect proof of polyphenol availability. Plasma concentrations can provide individual or total polyphenols in plasma and can be measured through use of Folin-Ciocaltau (FC) assay. The Ferric Ion Reducing Antioxidant Power Assay (FRAP) is a method used for measurement of the ferric reduction ability of plasma. The ferric tripyridytriazine complex at low pH results in reduction to the ferrous form. Test conditions are favorable to the complex reduction and the development of an intense blue color but only when a reductant or antioxidant is present. Linear rates in absorbance changes are noted over a range with antioxidant mixtures that is wide and includes both plasma and solutions that are inclusive of antioxidants."

Abstract
In this article, the writer explains that Crohn's disease is a debilitating bowel disease that has no known cause and very limited treatment options. The writer then discusses symptoms and the diagnosis of Crohn's disease. The writer maintains that individual and long-term counseling with an individual who is particularly sensitive to the devastating effects of chronic illness, and specifically "invisible" illnesses as one counselor puts it is the key approach to maintenance counseling for Crohn's disease. The writer concludes that just as the disease is variable in individuals so must the approach to resolving the many issues that are faced by individuals who have it.
From the Paper
"The disease itself is a clear robber of vitality, as the individual does not get the needed nutritional elements to gain weight, and in women mature sexually and potentially menstruate for the first time. The body is placed in position of shock with regard to physical growth and development and if the disease's onset is early enough this can stunt growth for life or completely destroy one's body image, another potential psychological problem. Thompson points out that the age group of typical onset is particularly vulnerable to impatience and therefore may feel devastated by the length of time it takes to elicit treatment results, and restore the body to its normal state, and appearance."

C-Reactive Protein, 2008.
This paper provides a critique of the article 'Effects of Antidiabetic and Antihyperlipidemic Agents on C-Reactive Protein' by P. Dandona.

»
Click here to show/hide summary
Abstract
In this essay, the writer notes that Dandona's article entitled 'Effects of Antidiabetic and Antihyperlipidemic Agents on C-Reactive Protein', centers on type 2 diabetes mellitus (DM) and the increased risk of cardiovascular disease. The writer discusses that insulin resistance in type 2 DM predisposes patients to develop cardiovascular disease, and has the associated risk factors for atherosclerosis, a chronic inflammatory disease of the arteries. The writer notes that higher CRP concentrations are found in patients with type 2 DM and Dandona theorizes that reducing these concentrations could have clinical benefit. As glucose and lipid levels are also often elevated in type 2 DM patients, an agent that affects all three of these would be beneficial to patients. The writer maintains that Dandona's article is a retrospective exploration of literature on antidiabetic and antihyperlipidemic agents which reduce these factors.
Outline:
Abstract
From the Paper
"The complex metabolic disorder that is type 2 DM is characterized by chronic hyperglycemia. In addition, due to the patient's insulin resistance, due to impaired insulation secretion and/or insulin action, there is also disturbances in lipid, carbohydrate and protein metabolism. This predisposes the patient to the development of cardiovascular disease, due to the proinflammatory and hypercoagulable state. As Dandona notes, an elevated CRP concentration is a predictor of cardiovascular events, in fact, it is a far better indicator than low-density lipoprotein cholesterol (LDL-C) even amongst healthy people. Although previous research indicates that CRP does not initiate atherosclerosis, but instead progresses the disease, the fact that CRP inhibits nitric oxide production suggests that it also has a role in the initiation of atherosclerosis as well."

Abstract
This paper explains that Francis Crick and James Watson are the only names associated with the discovery of the DNA molecule; however, many scientists were involved. The author points out that the technological applications of DNA-science have led to a wide variety of advances in crop production, livestock development, forensic sciences, law enforcement, paternity testing and practically limitless therapeutic medical uses. The author then discusses the latest and most controversial DNA-based research - stem cell science. The author of the paper contends that the primary impetus for the opposition to stem cell research from religious beliefs as well as their intrusion into secular law and bioethics, represents an entanglement of church and state in violation of U.S. constitutional principles.
Table of Contents:
Introduction
Background and History of Discovery
Technological Relevance of DNA Science
Modern Applications of DNA Science
Ethical Controversies
Conclusion
From the Paper
"In addition to providing the organs themselves, stem cell technology will also revolutionize the entire organ transplant field by eliminating the need for careful screening and tissue matching, and especially, for anti-rejection drugs. Presently, organ transplantation - whether from living donors or cadavers - requires the recipient to take powerful anti-rejection medications to suppress the body's natural response to foreign tissue, usually for life. Immune-system suppression are a necessary and worthwhile consequence of foreign organ implantation, but only because the alternative is premature death."

Abstract
This paper discusses Nancy Stephan's work, "The Hour of Eugenics: Race, Gender, and Nation in Latin America," in which she illustrates effectively how race and gender were important tools in the building of nations in Latin America. The paper examines Stephan's arguments and discusses how it relates to the history of eugenics in Mexico and Argentina, in particular.
From the Paper
"In Mexico, there was actually a short-lived experiment with sterilization based on eugenics. The Mexican Society of Eugenics was launched, in 1932, during what Stepan describes as a period of conservatism and political nationalism, a form of extreme patriotism. During this time fanatical declarations by political leaders had great impact. If the Mexican "race" was to be improved and not watered down, some members of the eugenics society declared, sex education was needed and even "eugenic sterilization."
"In 1921 sterilization in Mexico had already been implemented for criminals. And, by 1932, the fanatically anticlerical governor of Veracrux, Adalberto Tejada, authorized the first (and only) eugenic sterilization law in the nation. Tejeda's program of sterilization primarily targeted the Catholic Church than it was for any kind of pure race promotion, but it also was a program that was launched following the successful, science-backed, Mexican sterilization of improving the quality of livestock."

From the Paper
"The research showed that the ability to identify male-specific DNA renders polymorphic Y-chromosomal sequences an invaluable addition to the standard panel of autosomal loci used in forensic genetics. Y-STR haplotyping is particularly important for sensitive typing of male DNA in mixed stains as well as for rapid assortment of biological crime scene evidence. Moreover, Y chromosomal profiling can trace back paternal lineages into the past and has thus been proven a useful tool in genealogical and kinship testing. The research also showed that the individuality of the male-specific part of the Y chromosome can be optimally explored by the Y-STR haplotype analysis using a set of highly variable short tandem repeat markers approved by the forensic and scientific community."

Summary
From the Paper
"Periodontal disease affects up to 90% of the population and surgery has been the first choice of therapy. Surgery, however, does not restore lost periodontium. Restoration can happen if periodontal ligament cells can colonize root surfaces over gingival epithelial cells, gingival fibroblasts or osteoblasts. The application of microporous membranes under periodontal flaps during surgery eventually brought this effect about. A biodegradable membrane would make a follow-up surgery unnecessary and benefit both patient and surgeon from further health condition and cost."

Sensory Adaptation, 2008.
An examination of sensory adaptation.
780 words (approx. 3.1 pages), 3 sources, MLA, $ 27.95

Click here to show/hide summary
Abstract
This paper discusses sensory adaption, in which the nerves begin to cease to send as much information to the brain after a prolonged exposure to stimuli.That paper points out that this occurs in all five senses of smell, taste, touch, hearing, and sight. The paper holds that adaptation is a normal part of sensation in the human body, with all sensing receptors of the body sending messages to the areas of the brain that process and deal with it, the occipital area and the thalamus. The paper concludes that, when the senses become overloaded, the sections of the brain, as well as the nerves, adapt to the increased intense stimuli by shutting it off to some extent, and in some cases altogether, until a change in sensation occurs.
From the Paper
"The nose senses odors by picking up miniscule odor-bearing particles which are floating about in the air we are breathing. When these particles intercept the moist nerve endings in the interior of the nose, called the sensory receptor cells, there is a spike in the pattern of nerve impulses sent to the thalamus. The nerves may continue to send intense stimulation for a while, but eventually the perception of the intensity declines. This is neurologically explained by the adaptation phenomena. The nerve endings begin to adapt to the new odor and consider it normal, thus ceasing to send so much information about the foreign element in the air with a coordinating decline in the frequency of impulses. Within the brain, the thalamus ceases to respond to an intense pattern of stimulation, as well. Once the odor is gone (say, you walk out of a foul-smelling room), your nose tells you that there is a change once more, perhaps a more pleasant odor it detects (Typo 1)."

Summary and Discussion
Conclusion
From the Paper
"Over the course of the twentieth century, research into the development of the human mind has led to a more integral understanding of behavior, learning and cognition. Although the insight garnered through research has answered a number of pertinent questions, the reality is that this research has raised as many, if not more, questions than it is has answered. This is because as understanding of the human mind expands, the relationship between the body and the mind becomes more integrated and complex, requiring researchers to understand both dimensions of human existence in order to garner a complete comprehension of the human experience."

Conclusion
From the Paper
"The human respiratory system is a well-developed and complex system involving many different organs such as the nasal cavity, pharynx, trachea and the lungs. Though the actual physiological function of breathing begins only at birth, the development of the respiratory tract, the diaphragm and the lungs occur much earlier in the embryonic stage. Structural and functional changes continue from infancy to adulthood and into old age, as the respiratory system matures with age. There are various diseases of the respiratory system such as asthma, tuberculosis, chronic obstructive pulmonary disease (COPD), emphysema, lung cancer, etc. While Asthma is a genetic disease, Tuberculosis, lung cancer, etc, are acquired pulmonary diseases. Life style and environmental factors are important in contributing to and increasing the susceptibility to respiratory disorders. The following discussion includes a brief overview of the structural development of the human respiratory system followed by an overview of COPD and Tuberculosis, two of the prevalent diseases of the respiratory system, and their impact on occupational performance."
