Ceramide Kinase And Ceramide-1-Phosphate, Dayanjan Wijesinghe Nov 2008

Ceramide Kinase And Ceramide-1-Phosphate, Dayanjan Wijesinghe

Theses and Dissertations

Ceramide-1-phosphate (C1P) is a bioactive lipid that has been implicated in many biological processes. Our laboratory has conclusively demonstrated its role in inflammation via activation of cPLA2α. The only known enzyme to date responsible for direct synthesis of C1P is ceramide kinase. Very little was known about this enzyme in terms of its enzyme kinetics and substrate specificity. As CERK is an enzyme that acts on membrane lipids, its kinetics cannot be studied using standard bulk dilutions methods. Thus we developed a surface dilution approach using Triton X 100 mixed micelles for studying the kinetics of CERK. We discovered that …


New Approaches To Ecologically Based, Designed Urban Plant Communities In Britain: Do These Have Any Relevance In The United States?, James D. Hitchmough Nov 2008

New Approaches To Ecologically Based, Designed Urban Plant Communities In Britain: Do These Have Any Relevance In The United States?, James D. Hitchmough

Cities and the Environment (CATE)

This paper discusses the reasoning behind the development of a new approach to designed urban planting with grasses, forbs and geophytes that has been undertaken at the University of Sheffield over the past 15 years. The resulting plant communities are the result of applying contemporary ecological science to planting design, to maximize their sustainability whilst at the same time meeting the aesthetic and functional needs of the users of urban public landscapes. The geographical origin of the plants used in these communities varies according to the physical, ecological and cultural context in which they are to be used. In some …


Ecological Impacts Of Replacing Traditional Roofs With Green Roofs In Two Urban Areas, Tim Carter, Colleen Butler Nov 2008

Ecological Impacts Of Replacing Traditional Roofs With Green Roofs In Two Urban Areas, Tim Carter, Colleen Butler

Cities and the Environment (CATE)

Urban land cover is dominated by impervious surface that degrades both terrestrial and aquatic ecosystems relative to predevelopment conditions. There are significant opportunities for designers of urban landscapes to use alternative land covers that have multiple functions, benefiting both human and nonhuman components of the urban ecosystem. Vegetated (green) roofs are one form of alternative land cover that has shown the potential to provide a variety of ecological benefits in urban areas. We evaluated how stormwater retention, building energy and temperature, and rooftop habitat are influenced by the use of green roofs using test plots in Georgia and Massachusetts. Green …


Front-Loading Urban Stormwater Management For Success – A Perspective Incorporating Current Studies On The Implementation Of Retrofit Low-Impact Development, William D. Shuster, Matthew A. Morrison, Rachel Webb Nov 2008

Front-Loading Urban Stormwater Management For Success – A Perspective Incorporating Current Studies On The Implementation Of Retrofit Low-Impact Development, William D. Shuster, Matthew A. Morrison, Rachel Webb

Cities and the Environment (CATE)

Recent work into the implementation of low-impact development (LID) suggests that a decentralized, source-control approach has the potential to significantly reduce urban stormwater runoff quantity. The practice of retrofit stormwater management is currently dominated by demonstration projects, and some additional momentum is required to spur adoption and upscaling of LID practices so that the scale of this management approach can better match the scale of disturbance. This momentum may be provided in part by targeted research into effectiveness of stormwater best management practices insofar as research accounts for cost and effectiveness (e.g., water quality benefits, and actual stormwater capture) under …


Disproportionality As A Framework To Target Pollution Reduction From Urban Landscapes, Lawrence A. Baker, Bruce Wilson, David Fulton, Brian Horgan Nov 2008

Disproportionality As A Framework To Target Pollution Reduction From Urban Landscapes, Lawrence A. Baker, Bruce Wilson, David Fulton, Brian Horgan

Cities and the Environment (CATE)

New federal water quality regulations regarding impaired waters and urban stormwater alongside a growing need to reverse eutrophication of urban lakes are creating demand to decrease nutrient export from urban landscapes, particularly lawns. We propose that Nowak’s disproportionality framework could be used to target specific households likely to generate disproportionate levels of nutrient export. The biophysical dimension would be based on landscape vulnerability (slope; soil type; proximity to lakes); the social dimension would target “inappropriate” lawn management behaviors leading to high nutrient export on these vulnerable landscapes. Understanding of lawn nutrient cycling (biophysical dimension) and homeowner beliefs and attitudes (social …


Conserving Biodiversity In Urbanizing Areas: Nontraditional Views From A Bird’S Perspective, John Marzluff, Amanda Rodewald Nov 2008

Conserving Biodiversity In Urbanizing Areas: Nontraditional Views From A Bird’S Perspective, John Marzluff, Amanda Rodewald

Cities and the Environment (CATE)

We review common population and community-level responses of wildlife to urbanization, and discuss how: (1) the amount and configuration of land cover and land use, and (2) the alteration of resources (e.g., type of vegetation, presence of food and water) and processes (e.g., natural disturbance regimes, species interactions, intensity of human recreation) within built environments influence animals, with special emphasis on birds. Although each landscape presents unique opportunities and constraints, we suggest that all urban areas have the potential to contribute to the conservation of biodiversity. The ecological value of urban areas may be promoted if planners, managers, and homeowners …


Landscape Sustainability In A Sonoran Desert City, Chris A. Martin Nov 2008

Landscape Sustainability In A Sonoran Desert City, Chris A. Martin

Cities and the Environment (CATE)

The objective of this paper is to discuss concepts of landscape sustainability in the Phoenix metropolitan area. Phoenix is situated in the greater Salt River Valley of the lower Sonoran Desert in the southwest United States. In this paper I use the ecological frameworks of ecosystem services and resiliency as a metric for understanding landscape sustainability. An assessment of landscape sustainability performance benchmarks were made by surveying research findings of scientists affiliated with the Central Arizona Phoenix Long Term Ecological Research Project (CAP LTER). In Phoenix, present day emphases on cultural, aesthetic, and habitat formation ecosystem services within an arid …


Urban Principles For Ecological Landscape Design And Maintenance: Scientific Fundamentals, Mary L. Cadenasso, Steward T. A. Pickett Nov 2008

Urban Principles For Ecological Landscape Design And Maintenance: Scientific Fundamentals, Mary L. Cadenasso, Steward T. A. Pickett

Cities and the Environment (CATE)

Urban ecology is a rapidly developing scientific discipline with great relevance to sustainable city design and management. Though several frameworks have been proposed in the last 10 years, urban ecology, as yet, has no complete, mature theory. There are, however, general principles emerging that may facilitate the development of such a theory. In the meantime, these principles can serve as useful guides for ecological landscape design and maintenance. This paper aims to use the principles to conceptually frame a series of papers to follow in this special issue. The main ecological principles concerning cities are that: 1) Cities are ecosystems; …

Predicting Intra-Urban Variation In Air Pollution Concentrations With Complex Spatio-Temporal Interactions, Adam A. Szpiro, Paul D. Sampson, Lianne Sheppard, Thomas Lumley, Sara D. Adar, Joel Kaufman Nov 2008

Predicting Intra-Urban Variation In Air Pollution Concentrations With Complex Spatio-Temporal Interactions, Adam A. Szpiro, Paul D. Sampson, Lianne Sheppard, Thomas Lumley, Sara D. Adar, Joel Kaufman

UW Biostatistics Working Paper Series

We describe a methodology for assigning individual estimates of long-term average air pollution concentrations that accounts for a complex spatio-temporal correlation structure and can accommodate unbalanced observations. This methodology has been developed as part of the Multi-Ethnic Study of Atherosclerosis and Air Pollution (MESA Air), a prospective cohort study funded by the U.S. EPA to investigate the relationship between chronic exposure to air pollution and cardiovascular disease. Our hierarchical model decomposes the space-time field into a “mean” that includes dependence on covariates and spatially varying seasonal and long-term trends and a “residual” that accounts for spatially correlated deviations from the …

Detection Of Recurrent Copy Number Alterations In The Genome: A Probabilistic Approach, Oscar M. Rueda, Ramon Diaz-Uriarte Nov 2008

Detection Of Recurrent Copy Number Alterations In The Genome: A Probabilistic Approach, Oscar M. Rueda, Ramon Diaz-Uriarte

COBRA Preprint Series

Copy number variation (CNV) in genomic DNA is linked to a variety of human diseases (including cancer, HIV acquisition, autoimmune and neurodegenerative diseases), and array-based CGH (aCGH) is currently the main technology to locate CNVs. Several methods can analyze aCGH data at the single sample level, but disease-critical genes are more likely to be found in regions that are common or recurrent among samples. Unfortunately, defining recurrent CNV regions remains a challenge. Moreover, the heterogeneous nature of many diseases requires that we search for CNVs that affect only some subsets of the samples (without prior knowledge of which regions and …

Exploring The Mialome Of Ticks: An Annotated Catalogue Of Midgut Transcripts From The Hard Tick, Dermacentor Variabilis (Acari: Ixodidae), Jennifer M. Anderson, Daniel E. Sonenshine, Jesus G. Valenzuela Nov 2008

Exploring The Mialome Of Ticks: An Annotated Catalogue Of Midgut Transcripts From The Hard Tick, Dermacentor Variabilis (Acari: Ixodidae), Jennifer M. Anderson, Daniel E. Sonenshine, Jesus G. Valenzuela

Biological Sciences Faculty Publications

Background: Ticks are obligate blood feeders. The midgut is the first major region of the body where blood and microbes ingested with the blood meal come in contact with the tick's internal tissues. Little is known about protein expression in the digestive tract of ticks. In this study, for analysis of global gene expression during tick attachment and feeding, we generated and sequenced 1,679 random transcripts (ESTs) from cDNA libraries from the midguts of female ticks at varying stages of feeding.

Results: Sequence analysis of the 1,679 ESTs resulted in the identification of 835 distinct transcripts, from these, a total …


Benthic Microalgae And Nutrient Flux In Florida Bay, Usa, Merrie Beth Neely Nov 2008

Benthic Microalgae And Nutrient Flux In Florida Bay, Usa, Merrie Beth Neely

USF Tampa Graduate Theses and Dissertations

The objective of this study was to address the relationship between benthic microalgal communities and the phosphate nutrient dynamics of Florida Bay sediments and how they relate to benthic and water column primary production. In situ phosphate (P) flux between the sediment and the water column was measured in three regions of Florida Bay. Differences in the ratio of inorganic to organic phosphate flux were found between the three regions in relation to the amount of phosphate measured in the water column. Based upon the average sediment flux in my study, more than 1600 metric tons of P would be …
