Abstract
This research paper reviews the acute effects of pecan nuts ingestion on plasma levels of nutrients, polyphenols and biomarkers of antioxidant status. It specifically discusses whether, after the consumption of pecans, there is any increase in plasma polyphenol concentration. It also discusses when the peak concentration for polyphenols in plasma occurs, after consumption of a pecan-containing meal. The paper then looks at whether there is there any increase in plasma antioxidant capacity after consumption of pecans. Finally, the paper discusses whether there is any decrease in plasma lipid peroxidation after pecan consumption.

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."

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."

Introduction
Biodiversity
Aquatic Ecosystem
Measurement of Microbial Diversity
Trophic Interactions in Aquatic Systems
Biogeochemical Cycling
Diversity and Aquatic System Functioning
From the Paper
"Although microorganisms are barely visible in the aquatic system, they play a very important role in the processes occurring in the system be it in the food web or in nutrient cycling of the system, also called biogeochemical cycle. According to Kiorboe (1993), the majority of the biological activity in pelagic systems are performed by microorganisms smaller than 100 m. Larger organisms, on the other hand, play a very minor role in the nutrient and energy cycling of the system."

Abstract
This paper explores the third chapter of Desmond Morris', "The Naked Ape," as it relates to the development of human children. It discusses the content of the chapter under discussion and describes Morris' view on imprinting. The paper compares Morris' view with that of L. Salk and his strong case for imprinting. It concludes that these individuals are very similar, but their methods differ.
From the Paper
"In the end, Desmond Morris relies heavily upon the work of Salk in the third chapter of his book. Instinctively, I am inclined to think that Morris is correct in dismissing left-handed cradling; I am also inclined to think that the matter is more complicated than he acknowledges - especially given the findings of later research. Fundamentally, I prefer Salk's findings to Morris' simple regurgitation of them; by engaging in original research, Salk gives his conclusions an authenticity that Morris does not. Furthermore, Morris' refusal to cite studies supporting the arguments of critics insisting that left-handed cradling is caused by "right-handedness" in society leaves the reader with the impression that he erected a "straw-man" so that his own argument would be strengthened."

Abstract
This paper discusses the social consequences that will result in traditional third world countries from gender imbalance due to a bias in male children, sex-selective abortion and female infanticide. Furthermore, the paper discusses the modern Western issue of the killing of infants who suffer from incurable illnesses. Specifically, the paper assesses the social acceptability of some nations in Western Europe that have in recent years attempted to enact legal protocols for neonatal euthanasia, by which the most severely ill infants may legally be killed following consultation between physicians, parents, and authorities.
From the Paper
"In contrast to the problem of mass, sex-selective infanticide in traditional cultures, in the West the issue of the killing of infants who suffer from incurable illnesses has recently arisen. It is important to clearly distinguish such euthanasia from infanticide proper, although opponents of such euthanasia are likely to argue that the distinction is not valid ("Outrage," 2004). In fact, euthanasia of both the elderly, the incurably ill, and infants (especially newborns) with incurable illnesses has taken place as long in Western nations as it has in other cultures, but only in recent years has it become a matter of controversy. One example of the controversy coming into a public debate is in the Netherlands, where in 2002, medical doctors from the University of Groningen working in cooperation with state prosecutors worked out what has come to be known as the Groningen Protocol, a set of guidelines for physicians treating severely ill infants who may not be capable of survival. According to these laws, physicians, in consultation with the infant's parents, social workers, and prosecutors, have the prerogative of making a decision concerning euthanasia in select and clearly limited situations. Of approximately 200,000 children born in the Netherlands annual, it is estimated that 600 of the most severely ill may be subject to physician-assisted euthanasia (Verhagen & Sauer, 2005). Whether this new attitude toward neonatal euthanasia will prevail and become more widely accepted remains to be seen."

Abstract
This paper discusses an aquatic ecosystem located in a botanical garden in which dragonfly larva eat stickleback fish, which eat daphnia. The author describes the dragonfly larva, the stickleback fish and the daphnia and points out that the actions of these three entities in this aquatic ecosystem transfer nutrients into energy as they move through the food chain. The author concludes that the presence of predators has an effect on the morphology of each of the species and any changes in their behavior affects the environment as a whole.
From the Paper
"A study by Arnqvist and Johansson (1998) considers ways in which the dragonfly larva may show the effects of adaptive phenotypic plasticity, meaning that the form of the insect based on environmental considerations, one of which is the action of predator-induced defenses in prey. Predation is known to affect the phenotypic expression of a wide range of traits in a way that reduces the impact of predation. Most studies have examined traits that exhibit switched plasticity and usually do not examine the ontogenetic growth trajectories of defense structures."
