Electronic Theses and Dissertations
This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm ...
Pharmaceuticals And Industrial Products In Crops: Economic Prospects And Impacts On Agriculture, 2015 University of California, Berkeley
Pharmaceuticals And Industrial Products In Crops: Economic Prospects And Impacts On Agriculture, Gregory D. Graff, Giancarlo Moschini
Iowa Ag Review
That biotechnology has brought changes to agriculture in a very short time is, by now, obvious. For the 2004 harvest, for example, it is estimated that 85 percent of U.S. soybean production and 45 percent of U.S. corn production will come from genetically modified (GM) varieties (89 percent and 54 percent, respectively, in Iowa). While the agricultural sector is still dealing with problematic trade effects caused by less-than-enthusiastic consumer acceptance and restrictive regulations overseas, the biotech industry is actively pursuing an array of R&D efforts that could make the current adoption of GM crops just the prototypical ...

SIUE Faculty Research, Scholarship, and Creative Activity
The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated ...

Community Health Faculty Publications and Presentations
Background: Many environmental factors have been independently associated with preterm birth (PTB). However, exposure is not isolated to a single environmental factor, but rather to many positive and negative factors that co-occur. The environmental quality index (EQI), a measure of cumulative environmental exposure across all US counties from 2000—2005, was used to investigate associations between ambient environment and PTB.
Methods: With 2000–2005 birth data from the National Center for Health Statistics for the United States (n = 24,483,348), we estimated the association between increasing quintiles of the EQI and county-level and individual-level PTB; we also considered environmental ...
Examining The Toxicity, Exposure, And Regulatory Approach To Potential Human Health Risks Of The Algal Toxin Domoic Acid, 2015 University of Massachusetts Boston
Examining The Toxicity, Exposure, And Regulatory Approach To Potential Human Health Risks Of The Algal Toxin Domoic Acid, Thomas H. Angus
Graduate Doctoral Dissertations
Domoic acid is a neurotoxin produced by the marine diatom genus Pseudo-nitzschia and causes cell death primarily in the area of the brain responsible for long-term memory. The resulting severe illness has been termed amnesic shellfish poisoning. Domoic acid accumulates in shellfish and planktivorous fish that consume Pseudo-nitzschia, resulting in exposure to humans through consumption of planktivorous seafood. A regulatory standard in seafood was developed shortly after its discovery in 1987 to protect against acute effects. This regulatory standard has not been revised despite significant recent data in the scientific literature.
This dissertation is divided into four sections: (1) an ...

Constructed as a wave-shaped altar composed of discarded plastic, Mourning Wave aims to highlight the role of oceanic plastic debris in relation to the damage being done to the environment by humans. The wave is painted black, a traditional color of mourning. Colorful discarded plastic lies within the crest of the wave. This debris was collected several times as a ...
Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, 2015 University of San Francisco
Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, Adam V. Radpour
Chemical dispersants are applied to spilled oil in marine environments when other, less controversial, methods are not adequate for the incident. They are considered to be a response method as opposed to a direct cleanup method, with the intended goals of reducing risk of exposure to sensitive shorelines, reducing environmental injury to surface-dwelling sea birds and marine mammals, and facilitating the biodegradation of spilled oil into the water column.
For this research, both surface and subsurface application of dispersants were evaluated in terms of oil characteristics and volume, and oceanic and atmospheric conditions. More data exists to support the effectiveness ...
A Geospatial Analysis Of Norovirus Outbreaks In California, And An Investigation Of The Impact Of Environmental Variables, 2015 University of San Francisco
A Geospatial Analysis Of Norovirus Outbreaks In California, And An Investigation Of The Impact Of Environmental Variables, Alexandra Groen
Previous studies and empirical evidence suggest norovirus outbreaks in California exhibit correlation with environmental variables and exhibit spatial spread patterns. Few studies have been done looking at what causes norovirus seasonality in temperate climates and more research is needed on the regional level. This study aims to find what relationships exist with outbreak occurrence and environmental variables in California, as well as any spatial patterns of spread or clustering of outbreaks. Spatial analysis tools were used to find any relationships between California norovirus outbreak data and environmental variables. The results showed a south to north spread of outbreaks in California ...

Biology Faculty Publications and Presentations
An expected global increase in bioenergy-crop cultivation as an alternative to fossil fuels will have consequences on both global climate and local air quality through changes in biogenic emissions of volatile organic compounds (VOCs). While greenhouse gas emissions may be reduced through the substitution of next-generation bioenergy crops such as eucalyptus, giant reed, and switchgrass for fossil fuels, the choice of species has important ramifications for human health, potentially reducing the benefits of conversion due to increases in ozone (O3) and fine particulate matter (PM2.5) levels as a result of large changes in biogenic emissions. Using the Community Earth ...

Acute Toxicity Of Β-N-Methylamino-L-Alanine (Bmaa) To Fathead Minnow (Pimephales Promelas) And Zebrafish (Danio Rerio), Jiayi Wang
Dissertations & Theses in Natural Resources
β-N-methylamino-L-alanine (BMAA) is a neurotoxic amino acid produced by most species of cyanobacteria. Exposure to BMAA has been hypothesized as a cause of ALS and possibly Parkinson’s and Alzheimer’s diseases for several decades. Both in vitro and in vivo experiments revealed that exposure to elevated concentrations of BMAA can damage motor neurons and cause motor dysfunctions. However, the exact mechanism of BMAA-induced neurotoxicity has not been well understood.
Based on the available literature and in spite of its water-soluble and non-protein nature, BMAA appears to be able to bioaccumulate in organisms. The ubiquity of cyanobacteria and the potential ...
Analysis Of Nanoparticle Exposure On Legionella Pneumophila Biofilm Morphology And Host-Bacteria Interactions, Tara Diane Raftery
An increase in the amount of money spent on nanotechnology has led to an increase in funding to support nanoparticle (NP) research. Due to their stable, beneficial properties, NPs are found in daily consumer products such as bike frames, socks, cosmetics, and sunscreens. As a result of this, these NPs have the potential to enter the environment and interact with various organisms that play integral roles in the ecosystem as a whole. The effect that NPs have on aquatic systems is largely unknown and understudied. Biofilms are an important structural and functional part of aquatic ecosystems, and comprise various microorganisms ...

Investigating The Bioactive Constituents Of The Edible Blue-Green Alga Spirulina Platensis, Georgette Appiah-Pippim
Honors Scholar Theses
More people die annually from cardiovascular disease than from any other cause. Two risk factors for cardiovascular disease are hyperlipidemia and inflammation. Current drugs that are prescribed to regulate lipid levels often have adverse effects such as liver dysfunction. Blue-green algae (BGA), also known as cyanobacteria, have been consumed for years for their health benefits because they are believed to increase energy and prevent disease. One genus of edible blue-green algae is Spirulina plantesis (SP, Spirulina). Various studies have shown that Spirulina may have anti-cancer and anti-inflammation and anti-bacterial properties. In a previous study, Spirulina platensis lowered triglyceride and cholesterol ...

An Evaluation Of Carbon Concentrations Associted With Biodiesel Particulate Matter In An Underground Metal Mine, David Evans
Graduate Theses & Non-Theses
Exposure to diesel particulate matter from diesel exhaust has been shown to have adverse health effects in humans. In 2012 The International Agency for Research on Cancer classified diesel exhaust as a group 1 know human carcinogen. Because of the associated health effects, there has been a strong push to reduce the amount of diesel exhaust present in the mining industry. Biodiesel is one to the more common and promising control options used to reduce the amount of diesel particulate matter that is generated during fuel combustion. The use of biodiesel over petroleum diesel has been shown to reduce not ...
Microbial Communities Of The Providence River, 2015 Bryant University
Microbial Communities Of The Providence River, Jacqueline Kratch
Honors Projects in Science and Technology
The Providence River has been industrialized for over one-hundred years. Industries such as oil storage and metal recycling facilities have left high levels of pollutant metals, including lead (Pb), in the soil and water. The elevated Pb concentrations in these environments influence the selection of Pb resistance mechanisms in the bacterial community1. One mechanism of heavy metal resistance is the Pb efflux pump, consisting of proteins in the cell membrane that aid in the transport of Pb out of the cell2. In this study we investigated the co-occurrence of Pb efflux pumps and antibiotic efflux pumps in bacteria from Pb ...
