An Investigation Into The Effects Of Structural Isomers Of Salicylic Acid On Propionibacterium Acnes, Ireland Burch

Capstone Research Projects

Acne is caused when the sebaceous glands in the skin are unable to secrete an oily substance, called sebum, onto the surface of the skin. This is because the opening of the follicle is clogged from a mixture of skin cells and sebum. The opening of the follicle becomes plugged when the cells from the lining of the follicle are shed too quickly and clump together. Because Propionibacterium acnes (P. acnes) bacteria feed off sebum, they are then able to grow in the plugged follicle. Acne is caused by the inflammation that results from the chemicals and enzymes produced from …

Economic Efficiency And Consumer Choice Theory In Nutritional Labeling, Michael Mccann

Law Faculty Scholarship

As more Americans consume fast food each year, more Americans are contracting serious diseases related to obesity. Considering that obesity ranks second behind tobacco use as the largest contributor to mortality rates in the United States, and also that it gives rise to greater publicly funded health care expenses than does tobacco, this phenomenon begs the obvious question: To what extent does the growing consumption of fast food contribute to the obesity epidemic and the incidence of disease? If the answer indicates a meaningful contribution, a natural follow-up question then emerges: In a sensible legal system, what instruments would best …

Levels Of Citation Of Nonhuman Animal Studies Conducted At A Canadian Research Hospital, Anne Innis Dagg, Troy K. Seidle

Experimentation Collection

The publication of scientific articles that receive few or no citations raises questions of the appropriate use of resources as well as ethics. In the case of animal research, the ethics issue extends beyond human patients to nonhuman animals, as the research subjects them to pain and, typically, to death. This study is a citation analysis of animal research conducted at Toronto's Hospital for Sick Children (HSC). Of the 594 publications (1990 to 1995) on animal research by affiliates of HSC, 29% received Iower than 10 citations in a 10-year period. We compare the research history of 13 "best" and …

Neurologically Plausible Distinctions In Cognition Relevant To Drug Use Etiology And Prevention, Alan W. Stacy, Susan L. Ames, Barbara J. Knowlton

CGU Faculty Publications and Research

This article outlines several distinctions in cognition and related topics in emotion that receive support from work in cognitive neuroscience and have important implications for prevention: implicit cognition, working memory, nonverbal memory, and neurobiological systems of habit. These distinctions have not been widely acknowledged or applied in drug use prevention research, despite their neural plausibility and the availability of methods to make this link. The authors briefly review the basis for the distinctions and indicate general implications and assessment possibilities for prevention researchers conducting large-scale field trials. Subsequently, the article outlines a connectionist framework for specific applications in prevention interventions. …

Neuroplasticity And Functional Recovery: Training Models And Compensatory Strategies In Music Therapy, Felicity Baker, Edward A. Roth

BRAIN Lab Research

New research developments in the recovery of function following neurological trauma as well as basic and applied research relevant to music perception and production, seem to point to the suggestion that specific music therapy interventions that directly address the restoration of function as opposed to developing compensatory mechanisms, in certain circumstances, may now be a more appropriate treatment approach. We will address the issue of appropriate timing for the introduction of each strategy and discuss potential outcomes of each approach. As one might imagine, much of this research is published in the neurological journals, which music therapists may not regularly …

Life Without Gpr7, The Neuropeptide W1 Receptor: Regulation Of Energy Homeostasis By Gpr7 And Its Endogenous Neuropeptide Ligands, Makoto Ishii

Student Theses and Dissertations

Classic lesion experiments from the 1940s have established the hypothalamus as playing an essential role in controlling energy homeostasis. Gold-thioglucose (GTG) induces lesions in the ventromedial nucleus of the hypothalamus (VMH) resulting in hyperphagia and obesity. To identify genes involved in the hypothalamic regulation of energy homeostasis, we employed a screen to search for genes that were dysregulated in GTG induced obese mice. In this screen, GPR7, the endogenous G protein-coupled receptor (GPCR) for the recently identified ligands neuropeptide B (NPB) and neuropeptide W (NPW), was found to be specifically down-regulated after GTG treatment. The physiological role of GPR7 was …

Clark’S Nutcrackers (Nucifraga Columbiana) And The Effects Of Goal-Landmark Distance On Overshadowing, Aleida J. Goodyear, Alan Kamil

Papers in Behavior in Biological Sciences

Three groups of Clark’s nutcrackers (Nucifraga columbiana) were trained to find a goal location defined by an array of 4 landmarks that varied in goal–landmark distance. The arrays for each group differed in the distance of the closest landmark and contained goal–landmark distances that were common across groups, allowing for the examination of the effects of both relative and absolute goal–landmark distance on encoding of a landmark array. All 3 groups readily learned the task and were subsequently tested in probe tests with only single landmarks from the array available. Search error in tests with single landmarks was …

The Geometry Of Foraging Patterns: Components Of Thoroughness In Random Searching, Alan B. Bond

Papers in Behavior in Biological Sciences

A Monte Carlo simulation of the movements of a randomly-searching predator was used to develop a novel geometrical measure, the "thoroughness" of the search, and to investigate the effects of meander, turn asymmetry, and path length. Thoroughness varied directly with the meander and the square of the asymmetry measure and remained relatively invariant with path length. The regularity of its relationship to the generating parameters of the search and the ease with which it may be estimated from field data recommend thoroughness for use in characterizing empirical search patterns and in testing for the occurrence of systematic searching.

Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum

Environmental & Global Health Faculty Research

Because most American adults do not meet recommended physical activity guidelines, the need for new and innovative strategies is apparent. The current study employed public posting in an attempt to increase walking behavior in a worksite setting. Pedometer generated data was publicly posted in a prominent location in the worksite. In our study that utilized a pre-experimental design, we found that walking steps were statistically higher during the intervention and in a post intervention period as compared to the baseline data. We conclude that the public posting of physical activity data has the potential to increase walking behavior.

Effects Of Training And Melodic Features On Mode Perception, Amber M. Leaver, Andrea R. Halpern

Faculty Journal Articles

The two modes most widely used in Western music today convey opposite moods—a distinction that nonmusicians and even young children are able to make. However, the current studies provide evidence that, despite a strong link between mode and affect, mode perception is problematic. Nonmusicians found mode discrimination to be harder than discrimination of other melodic features, and they were not able to accurately classify major and minor melodies with these labels. Although nonmusicians were able to classify major and minor melodies using affective labels, they performed at chance in mode discrimination. Training, in the form of short lessons given to …

Development Of A Multi-Disciplinary Ecological Model For Childhood Obesity, David W. Hey

Kinesiology and Public Health

During the past two decades the prevalence of childhood obesity has steadily increased in the United States. An ecological model of health behavior change has been recommended to address the rise in childhood obesity. The purpose of this study was to build a comprehensive, multi-disciplinary, ecological childhood obesity model by examining past theory and research in 25 journals covering five disciplines over a decade (1993-2002).

To identify environmental antecedents, this study collapsed 10 existing ecological models of obesity prevention and divided resultant antecedents (n=94) into five ecological categories (social norms/national policies, community factors, school factors, family/peer or interpersonal …

Do Recent Data From The Seychelles Islands Alter The Conclusions Of The Nrc Report On The Toxicological Effects Of Methylmercury?, Alan H. Stern, Joseph L. Jacobson, Louise Ryan, Thomas A. Burke

Wayne State University Associated BioMed Central Scholarship

Abstract

In 2000, the National Research Council (NRC), an arm of the National Academy of Sciences, released a report entitled, "Toxicological Effects of Methylmercury." The overall conclusion of that report was that, at levels of exposure in some fish- and marine mammal-consuming communities (including those in the Faroe Islands and New Zealand), subtle but significant adverse effects on neuropsychological development were occurring as a result of in utero exposure. Since the release of that report, there has been continuing discussion of the public health relevance of current levels of exposure to Methylmercury. Much of this discussion has been linked to …
