Biliary Tract Obstruction In Chronic Pancreatitis, Abdallah Abdulkarim, Jake E. J. Krige, Philippus C. Bornman

General Surgery, East Africa

Bile duct strictures are a common complication in patients with advanced chronic pancreatitis and have a variable clinical presentation ranging from an incidental finding to overt jaundice and cholangitis. The diagnosis is mostly made during investigations for abdominal pain but jaundice may be the initial clinical presentation. The jaundice is typically transient but may be recurrent with a small risk of secondary biliary cirrhosis in longstanding cases. The management of a bile duct stricture is conservative in patients in whom it is an incidental finding as the risk of secondary biliary cirrhosis is negligible.

Initial conservative treatment is advised in …

The Role Of Zinc And Reactive Oxygen Species In The Regulation Of Endothelial Nitric Oxide Synthase, Jason Michael Wilham

Graduate Student Theses, Dissertations, & Professional Papers

Persistent pulmonary hypertension of the newborn (PPHN) is a very serious disease affecting nearly 5 in 1000 newborns each year. The development of PPHN has been linked to a decrease in the activity and expression of endothelial nitric oxide synthase (eNOS). Thus, it is critical to understand the mechanisms by which eNOS is regulated to identify new pathways and novel therapies for PPHN. eNOS is dynamically regulated at the transcriptional, post-transcriptional, post-translational, and developmental levels, however mechanisms of this regulation are unresolved. Our data indicates that increases in eNOS expression and activity correlate with increased cellular levels of labile zinc …

Reducing Dental Mercury Discharge In Missoula, Montana: Collaborative Opportunities, Jamie Elaine Silberberger

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this paper is to provide assistance in developing a program to control the release of dental mercury amalgam in Missoula, Montana. To do this, three research components were carried out. The first consisted of a survey to determine whether Missoula dentists are following the American Dental Association’s (ADA) recommended Best Management Practices (BMPs) for mercury amalgam waste. The second component involved interviewing local dentists in an effort to include their voice in the process, as well as to determine what may motivate them to comply with a dental mercury control program. The final component of research involved …

Role Of Sodium Arsenite In Atherogenesis, Flavia Elias Pereira

Graduate Student Theses, Dissertations, & Professional Papers

Epidemiological studies as well as controlled animal studies have associated exposure to arsenic through drinking water with the development of atherosclerosis. In this study, we have shown for the first time that low and environmentally relevant concentrations of arsenic accelerate atherogenesis. The objective of this study was to elucidate the mechanisms of arsenic-induced atherosclerosis by (1) characterizing the time- and concentration-dependent effects of sodium arsenite [As(III)] on the development of atherosclerosis in ApoE-/- /LDLr-/- mice, (2) determining whether As(III)-induced peroxynitrite activates protein kinase C (PKC) isotypes, α and β, in human aortic endothelial cells (HAECs) and (3) determining the effects …

Maternal Effects And Sexual Selection In The Heliconia Bug, Leptoscelis Tricolor (Hemiptera: Coreidae), Christine Whitney Miller

Graduate Student Theses, Dissertations, & Professional Papers

The early environment experienced by organisms can have significant phenotypic effects that persist throughout life. Parents, mothers in particular, commonly determine these early environments. Maternal effects, or the influence of maternal phenotypes on offspring phenotypes, are therefore likely ubiquitous in natural populations. However, the frequency and evolutionary consequences of maternal effects are largely unknown. Here I show that maternal phenotypes can have large effects on offspring morphology, fecundity, and behavior. I theoretically explore the potential for these effects to resolve the long-standing "lek paradox" in the field of sexual selection. I also empirically investigate these effects in the heliconia bug, …

Action-Oriented Sustainable Agriculture Education: Attitudes Towards Nutrition And Agricultural Practices In Guaimaca, Honduras, Sarah Lynne Potenza

Graduate Student Theses, Dissertations, & Professional Papers

Agricultural policies and global economic forces negatively affect many small-scale farmers in developing countries, resulting in widespread micronutrient malnutrition and environmental degradation. This study explores the connections between these issues, and the efficacy of using participatory education on sustainable agriculture to address them at a local level. Specifically, it evaluates an action-oriented education and sustainable agriculture program in Honduras, from the perspective of the participants and my own participation, as a means to improve agricultural practices and rural nutrition among subsistence farmers. As in many developing countries, access to land, poor soil conditions, steep hillsides, adverse climatic conditions, and limited …

Conservation Of Leopards In Ayubia National Park, Pakistan, Asad Lodhi

Graduate Student Theses, Dissertations, & Professional Papers

Lodhi, Asad M.S. May 2007 Wildlife Biology Conservation of leopard in Ayubia National Park, Pakistan Committee Chair: Dr. Daniel H. Pletscher Large carnivores are important for biodiversity and ecosystem function, yet are very difficult to conserve because of their large home ranges and conflicts with humans. I examined human-leopard conflicts in and near Ayubia National Park, Pakistan, to provide management recommendations for the conservation of leopards. Persecution of leopards by humans has been on the rise primarily due to depredation on livestock and risk to human lives. Since 1989, 16 humans have either been killed or injured in and around …

A Modern Examination Of Marcus Goldstein’S Mexican Immigrant Population Data: Comparisons Of Mexican-Born And U.S.-Born Children And Adults Living In 1930’S America And Mexico, Amanda Katelin Gango

Graduate Student Theses, Dissertations, & Professional Papers

Modern statistical methods were employed in order to test the statistical validity and conclusions of Marcus Goldstein’s (1943) original data consisting of nineteen different anthropometric measurements on two different groups of individuals, Mexican immigrants and their children residing in the San Antonio, Texas area and Mexican natives living in central and northern Mexico. Using independent samples T-tests, an analysis of covariance, and an RMET analysis, significant differences among variables compared between Mexican natives and Mexican immigrants and their U.S. born children were identified and interpreted. Variation was attributed to geographical location and length of time spent in the United States. …

Free Living Nitrogen-Fixation In Ponderosa Pine/Douglas-Fir Forests In Western Montana, Tricia Burgoyne

Graduate Student Theses, Dissertations, & Professional Papers

Nitrogen (N) is a primary limiting nutrient in all ecosystems. Therefore, a thorough understanding of N cycling processes in forest ecosystems is required to minimize N losses to fire, harvesting, and other forms of land management. The influence of fire, fire exclusion and forest restoration treatments on non-symbiotic N-fixation in the forest ecosystem has been poorly studied. Over the past 100 years, fire has been greatly excluded from low elevation, fire maintained forests as a result of active fire suppression as well as land management activities that create discontinuities in landscape fire patterns. Previous studies have shown this activity to …

Moving Boxes Closer To Home: The Role Of Sysco Corporation In Food System Localization, David Scott Kennedy

Graduate Student Theses, Dissertations, & Professional Papers

Increasing demand for local food by foodservice establishments creates new opportunities and challenges for the local food movement. While there is considerable potential for local suppliers to sell more product volume closer to home, the business needs of foodservice establishments may not be compatible with direct marketing approaches that have fueled the growth of the movement. Foodservice establishments typically rely on distributors to provide them with the majority of their food. Drawing on the success of direct marketing, new indirect marketing approaches that link producers and consumers through intermediaries are increasingly advanced within food system localization. The dominance of SYSCO …

Multi-Partner Mutualisms: Interactions Among The Mountain Pine Beetle And Two Ophiostomatoid Fungal Associates, Katherine Patricia Bleiker

Graduate Student Theses, Dissertations, & Professional Papers

I investigated interactions between the mountain pine beetle (Dendroctonus ponderosae) and its two main ophiostomatoid fungal associates,Grosmannia clavigera and Ophiostoma montium, as well as interactions between the two fungi. The main research questions were: What drives bark beetle fungal interactions? What is the nature of the interaction between the two species of fungi? I tested the hypothesis that the fungi provide nutritional benefits to the bark beetles. Evidence suggests a nutritional role of fungi in the diet of bark beetles because beetles emerging from attacked trees carrying G. clavigera were larger than beetles carrying O. montium, which in turn were …

No Simple Tradeoffs: Centaurea Plants From America Are Better Competitors And Defenders Than Plants From The Native Range, Wendy Margaree Ridenour

Graduate Student Theses, Dissertations, & Professional Papers

Two non-mutually exclusive hypotheses for invasive success have important evolutionary implications. The 'natural enemies' hypothesis posits that exotic invaders explode in abundance because they are not suppressed by specialist herbivore consumers in their invaded range. The 'novel weapons' hypothesis posits that exotic invaders explode in abundance because they possess biochemicals that are more effective against evolutionarily naïve plants, microbes, and generalist herbivores than against those species that have evolved tolerance in their communities of origin. I explored the potential for novel allelopathic or herbivore defense biochemicals as a potential alternative mechanism to tradeoff-driven evolution of increased competitive ability in invasive …

Predictors Of Adl Disability In Culturally Diverse Older Adults, Fernanda Holton

LSU Master's Theses

Almost 42% of adults over 65 years of age live with at least one disability. Further, people of lower socioeconomic status and Blacks have greater risks for disability than Whites and individuals at higher socioeconomic status. The consequences of disability include loss of independence, decreased quality of life, increased chances of depression, consumption of health care services, and institutionalization. The purpose of this study was to utilize the disablement process framework to examine the contribution of physical function, dyspnea, and pain to disability in activities-of-daily-living (ADL) in culturally diverse older adults (i.e., diverse according to race, income, and education). Participants …

Quantitative And Spatial Analysis Of The Microscopic Bone Structures Of Deer (Odocoileus Virginianus), Dog (Canis Familiaris), And Pig (Sus Scrofa Domesticus), Zoe Hensley Morris

LSU Master's Theses

Structure and morphology of bone tissue are variable by species. The influence of different factors on structure and morphology is still debated. Qualifying and quantifying these differences are necessary in the evaluation of fragmentary bones in order to identify specific species. To understand the influence of species of origin on the microscopic structure of bone tissue, the influence of developmental and biomechanical forces specific to a skeletal element must also be assessed. This research is a preliminary analysis of the histological bone structures in terms of their area, density and spatial organization. To achieve this research goal, the cross-section of …

Anaesthesia For Interventional Neuroradiology, Aliya Ahmed

Department of Anaesthesia

There have been rapid and significant advances in diagnostic and interventional radiology, including interventional neuroradiology, in recent years. Many intracranial vascular pathologies are being successfully managed by endovascular interventional neuroradiology techniques. These techniques include procedures like embolization of vascular tumours and arterio-venous malformations, coiling of cerebral aneurysms. etc. The support of anaesthesia team is requested for these therapeutic endovascular neuroradiological procedures. The main aims of the anaesthesiologist during any interventional neuroradiology procedure are provision of a physiologically stable and immobile patient, alteration of arterial blood pressure as necessary, and appropriate and timely management of complications. Provision of anaesthesia in remote …

Characteristics Of Cooked Chickpeas And Soybeans During Combined Microwave–Convective Hot Air Drying, Aoife Gowen, Nissreen Abu-Ghannam, Jesus Maria Frias, Jorge Oliveira

Articles

Moisture content, shrinkage, water activity (Aw), color and texture of cooked chickpeas and soybeans during convective, microwave and combined microwave–convective drying were studied. Combined drying was significantly (P < 0.05) faster than either convective or microwave drying, and resulted in less shrinkage of the dehydrated product. Rapid burning occurred when samples were dried below a Aw of 0.27 ± 0.07 for chickpeas (P < 0.05), and 0.13 ± 0.04 for soybeans (P < 0.05). Both chickpeas and soybeans displayed a transitional behavior in texture when dried to a Aw below 0.40 ± 0.10 (P < 0.05) for chickpeas, and below 0.63 ± 0.15 (P < 0.05) for soybeans, when samples became brittle. Shelf stable dehydrated chickpea and soybean products with low water activity (Aw = 0.35) and good visual quality could be obtained within 14 min of combination drying.

Private Ordering And Intimate Spaces: Why The Ability To Negotiate Is Non-Negotiable, Michele Goodwin

Michigan Law Review

This review moves beyond a critique of Cherry's study to incorporate a radical new way of thinking about organ commodification as a social justice issue. Part I provides a brief empirical overview of organ demand in the United States, offering an alternative perspective and introducing data illexamined in commodification debates. Part II challenges the notion that private ordering abandons liberal and egalitarian values in favor of individualism over communitarianism. It also acknowledges the limitations of private ordering and addresses how its more problematic features, including the abuse of power, might be avoided. Part III argues for a hybrid system that …

Federal Rule Of Civil Procedure 52(A) As An Ideological Weapon?, Bryan Adamson

Faculty Articles

In this article, the author explores Federal Rule of Civil Procedure 52(a) and standard of review choice to determine whether appellate judges can exploit its terms to pursue ideological goals. The author examines the operative terms of Rule 52(a), viz., findings of fact, clear error, and documentary evidence, and concludes that they are so malleable as to give appellate judges wide discretion in deciding whether clear error, de novo, or some other standard of review is to be applied. The article then goes on to identify fact typologies appellate courts invoke (historical, ultimate, constitutional, legislative, sociological, scientific, political, economic, jurisdictional), …

Fishery Conservation And Management Act Reauthorization: “A” For Effort, “C” For Substance, Madeline Kass

Faculty Articles

In one of its last acts of 2006, the 109th Congress passed the Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 (FCMRA), reauthorizing the nation's primary fishing law through the year 2013. The president signed on in early January 2007. Those involved in the reauthorization effort deserve kudos for achieving a successful bipartisan compromise, a relatively rare phenomenon in recent years. Congress also deserves praise for taking positive action towards improving existing law and for rejecting preliminary proposals designed principally to derail conservation efforts. Yet, in the face of unrelenting, catastrophic fish stock declines, it is unclear whether the …

Optimization Of Porcine Buccal Mucosa For In Vitro Evaluation, Upendra D. Kulkarni

University of the Pacific Theses and Dissertations

Porcine buccal mucosa has been extensively used as in vitro model to study the permeability of drugs and assess their potential to deliver through buccal route. Porcine buccal mucosa is found to be very similar to human oral mucosa in structure and function. However, the in vitro permeation studies across porcine buccal mucosa show high variability which is mostly due to the various experimental and biological variables that are often overlooked while conducting such studies.

The precise nature of the permeability barrier offered by the various tissue layers of buccal mucosa was investigated in this study. It was observed that …

Do Sagebrush Density And Vegetation Condition Affect Demography Of Brewer's Sparrows Nesting In The Blackfoot Valley?, Masanori Abe

Graduate Student Theses, Dissertations, & Professional Papers

Vegetation condition can influence habitat quality by altering food abundance, predator abundance and species composition, and microclimate. In some habitats, livestock grazing alters vegetation condition in ways that affect the breeding success of passerines. Most sagebrush-dominated habitats have been heavily grazed by livestock, and the total area of sagebrush has declined substantially. Owing to this habitat loss and change, numbers of various sagebrush-obligate birds have declined, the Brewer's Sparrow among them. I examined the effects of cattle grazing on Brewer's Sparrow reproduction. Grazed plots, at the study-site scale, were characterized by higher potential nest-sagebrush density, and canopy cover, a higher …

Gardening Programs In Schools: A Proposed Solution To Reverse The Consequences Of The Current American Food Culture, Charlotte Grace Blessey

Honors Theses

This thesis examines the problems with current food consumption and production practices, and proposes the implementation of school gardening programs as a possible remedy to these problems. Methods and procedures consisted of research on current publications, periodicals, internet sources and scholarly articles concerning these topics. It was found that current diet is a significant factor in widespread health problems facing populations today. This diet is intertwined with an environmentally destructive and vulnerable system of intensive industrial agriculture based on centralization, mass distribution, and standardization. School garden programs target children beginning at a young age and help to counter the culture …

Identification Of A 17-Nucleotide Splicing Enhancer In Hpv-16 L1 That Counteracts The Effect Of Multiple Hnrnp A1-Binding Splicing Silencers, Ziaomin Zhao, Joanna Fay, Stefan Schwartz, Helen Lambkin

Articles

Human papillomavirus type 16 (HPV-16) infections can in rare cases persist and cause lesions that may progress to cervical cancer. Cells in the lesions are not permissive for virus production, nor are cervical cancer cells. The intracellular environment is such that it prevents production of the highly immunogenic, viral structural proteins L1 and L2. One may speculate that inhibition of L1 and L2 expression is a prerequisite for persistence and cancer progression.We have therefore investigated how expression of HPV-16 L1 is regulated.We found that the only splice site in the HPV-16 late region, which is used to produce L1 mRNAs, …
