Abstract
The biochemical effects of LSD are an important area of research in contemporary neurological studies. Since it so severely affects the psychological state of human subjects, LSD research is thought to be a tool with which we will be able to further understand the complex interactions of brain chemicals, particularly serotonin and dopamine, and their respective receptors.

Abstract
This essay talks about the biochemical nature of the enzyme lactase. The paper includes a discussion of it's production, the reaction it catalyzes and the physiological effects of this enzyme. In particular the essay includes an explanation of the physiological effects experienced with a deficiency of lactase.

From the Paper
"Lactose is a disaccharide that is the principal carbohydrate found in milk and other dairy products. To digest lactose the enzyme lactase is required to catalyse the hydrolysis reaction to produce the monosaccharides glucose and galactose. This enzyme is usually present at birth but often decreases in activity as the child matures. The condition where an individual has a deficiency of lactase is known as lactose intolerance and produces symptoms such as nausea, cramps, bloating, gas, and diarrhea"

Summary and Conclusions

From the Paper
"Lead has been used by mankind for centuries, but the dangers associated with its use have only been identified fairly recently. The research showed that in spite of some progress in recent years, lead poisoning represents one of the leading preventable public health threats for young people in the United States and abroad today. The research showed that there are no safe levels of lead exposure for children, and lead levels as low as 10 [micro]g/dL have been shown to affect child development. A host of other health issues are implicated in lead poisoning as well, but most people tend to recover completely if appropriate treatments are provided in a timely manner. Finally, the research was consistent in emphasizing the inherent problems in addressing the problem of lead poisoning among low-income families where the exigencies of daily life preclude concern over this potential threat. Clearly, lead poisoning represents a challenging and ongoing threat to the nation's welfare, and public health officials continue to pursue increasingly aggressive campaigns to address the issue, but the studies to date suggest that these initiatives will remain ineffective unless and until the economic disparities that exist between the world's affluent and poor are addressed first."

Abstract
The paper analyzes the article "Biochemical Hypoglycemia in Female Nurses During Clinical Shift Work" to determine the efficacy and use of proper and best-fit research protocol. The paper evaluates the authors' use of a proper and identifiable research question, the presentation of a testable null hypothesis and the identification of the necessary independent and dependent variables. The paper also examines the statistical data analysis procedures and the usefulness of the research results. The paper demonstrates how the results of this article, although of topic importance, fail miserably in adhering to the protocol set forth for best-fit epidemiological research.

"Research, albeit philosophical, historical, descriptive, or experimental, is not simply a collection of random thoughts or numeric data reduced to paper (Van Dalen, 1966). Research of any type is a scientific endeavor that is defined, organized, and subjected to critical scrutiny and, above all, requires a scientific approach (Senter, 1969). Far more exacting is that research investigations must follow best fit research guidelines if the content is to be applicable to the phenomenon being investigated. Such an exacting process applies not only to quantitative research but qualitative research as well (Ohlson, 1998). The scientific approach to research is a special systematic form of controlled reflective thinking and inquiry. Of all types of research defined, that of the experimental investigation is the most well defined, constructed, and controlled as it is that upon which the prediction of future occurrences are dependent."

Abstract
Cites need for study re: biochemical mechanisms involved in CFS. Contends research is lacking in identifying the mechanisms that cause CFS. Extensive literature review covers severe & disabling fatigue & impact on daily functioning. Discusses symptoms of condition including sleep disturbances, pain, short-term memory loss, depression. Possible causes & characterizations of CFS. Conceptual framework. Research questions. Hypotheses. Research procedures & data analysis testing.

From the Paper
"Introduction
Chronic fatigue syndrome (CFS) is a clinically defined condition which is characterized by severe and disabling fatigue. This fatigue is accompanied by a combination of symptoms that typically include self-reported impairments in concentration and short-term memory, sleep disturbances, and musculoskeletal pain (Evengard, Schacterle & Komaroff, 1999; Wilson, Hickie, Lloyd & Wakefield, 1996).
CFS prevalence rates in the United States are estimated at a minimum of 4 to 10 cases per 100,000 adults 18 years of age or older (Fukuda & Gantz, 1995). In one U.S. study (Evengard et al., 1999), the prevalence among medical patients was found to be about 1%. A several-fold higher prevalence rate of self-reported..."

Abstract
In this article the writer discusses prostate cancer. The writer also examines some of the biochemical research that is being carried out to try and determine the causes of this type of cancer. The paper looks at the oxidative stress on cells and the effects of androgen. The writer discusses NSAID-associated gene protein and some of the multi-drug resistance associated proteins.

From the Paper
"Prostate cancer is a disease of aging brought about by changes in cellular biochemistry which result in an imbalance in the pro oxidant-antioxidant balance and in the cellular response to androgen which this brings about. Many advanced cases of prostate cancer become resistant to chemotherapy making the prognosis for those men dismal. It has been shown ... "

"Obsessive-compulsive disorders have been thoroughly studied for the past decade so that we now have several explanations for those behaviors which can range from the annoying to the life-destroying. Some explanations for OCDs will be examined, as well as the drugs which prove beneficial in their treatment.

In the late 1980s, television talk shows saw a steady stream of people who talked about a condition that had nearly wrecked their lives--obsessive-compulsive disorder (OCD). They wanted to tell others about the disorder and present the hope offered by a new experimental drug.

Ten years ago, OCD was thought to be comparatively rare; however, as the response to TV talk shows demonstrated, thousands of people were suffering from the same disorder. Zamula (1992) notes that as many as five million people in the United States.."

"Genetics is a scientific study of how physical, biochemical, and behavioral traits are transmitted from parents to their offspring. The word itself was coined in 1906 by the British biologist William Bateson. Geneticists are able to determine the mechanisms of inheritance because the offspring of sexually reproducing organisms do not exactly resemble their parents, and because some of the differences and similarities between parents and offspring recur from generation to generation in repeated patterns. The investigation of these patterns has led to some of the most exciting discoveries in modern biology."

"Lesch-Nyhan Syndrome is an inborn metabolic error caused by an enzyme deficiency which results in neurological, renal, and rheumatological problems. This paper will look at its genetic basis, the biochemical components of the syndrome, its pathophysiology, the role of genetic and biochemical knowledge and technology in the diagnosis, prognosis, and treatment of the disorder, as well as the current status and projected future directions research into the syndrome will take.
Lesch-Nyhan syndrome is characterized by hyperuricemia, choreoathetosis, dystonia, mental retardation, dysarthria, and compulsive biting of the lips and fingers. (Wong et al, 1996). It affects one in 400,000 to one in 100,000 live births. Although it affects only male children, women may be asymptomatic carriers and pass the mutation on to their offspring.."
