Blood Lead Concentrations In The Cat Population Of Tampa, Florida, Liesl M. Wiesen

USF Tampa Graduate Theses and Dissertations

Where lead pollutes urban soils, both human and animals risk exposure. This exposure gives rise to similar health risks across species. A group of 50 outdoor living cats from inner city Tampa, Florida were tested for blood lead concentration (BLC). Most cats had no measurable lead loads, 14 percent had levels less than or equal to 6 micrograms per decaliter. Soil samples were taken from the home location of each cat. None of these samples, which ranged from 2.6 microgram per gram to 170 micrograms per gram, had hazardous levels of lead. Overall, BLCs were lower than expected. In addition, …

Food For Early Succession Birds: Relationships Among Arthropods, Shrub Vegetation, And Soil, Richard N. Conner, Daniel Saenz, D. Brent Burt

Bulletin of the Texas Ornithological Society

During spring and early summer, shrub- and herbaceous-level vegetation provides nesting and foraging habitat for many birds. This study examined relationships among arthropod biomass and abundance, foliage leaf surface area, vegetation ground cover, soil characteristics, humidity, and temperature. Arthropod biomass was negatively correlated with humidity, and positively correlated with herbaceous ground cover and clay content in the soil. Management practices promoting herbaceous vegetation may enhance arthropod availability and thus foraging conditions for birds.

Culture, Climate And The Environment: Local Knowledge And Perception Of Climate Change Among Apple Growers In Northwestern India , Neeraj Vedwan

Journal of Ecological Anthropology

Human societies in mountainous areas have evolved specific ways of dealing with the constraints imposed by the environment. A number of anthropological studies have documented the existence of practices that can be considered adaptive in the context of mountain environments. In this paper, I present a case study of a society in transition, in the northwestern Himalayas of India, in which local knowledge—combining aspects of traditional knowledge and practice—is used by farmers to cognize and cope with the uncertainty in their environment. Focusing on the perception of changes in the amount and timing of snowfall over the last three decades, …

Freedom Fighters, Freedom Haters, Martyrs, And Evildoers: The Social Construction Of Suicide Terrorism, Cã©Cile Valã©Rie Van De Voorde

USF Tampa Graduate Theses and Dissertations

Suicide terrorism is characterized by the willingness of physically and psychologically war-trained individuals to die while destroying or attempting to annihilate enemy targets in furtherance of certain political or social objectives. Rooted in the historical, social, and psychological dimensions of international terrorism, suicide terrorism is neither a unique nor a new phenomenon. Its recent resurgence and the extensive media coverage it has received account for the misleading uniqueness of this violent, complex, and adaptive form of terrorism. This qualitative study examines the definitional and rhetorical processes by which suicide terrorism is socially constructed. Using a social constructionist theoretical framework coupled …

Arts In New Directions The Development And Application Of A Construct That Uses The Arts To Promote Transformation And Self-Actualization In Health Care And Education/Therapy, Alexxis Avalon

USF Tampa Graduate Theses and Dissertations

Artistic methods to evoke relaxation, spark creativity, and change self-perceptions are already being used by therapists, educators, and scientists. Interdisciplinary collaborations among researchers are developing to create new paradigms that incorporate the use of arts to empower individuals. By describing various connections between the arts and participants, researchers are looking at the expressive arts (including dance, music, drama, poetry, and visual arts) for transformation and self-actualization.The problem is that no construct is available to describe the transformation, "the conscious move from one deep structure of knowledge to another" (Wilber, 2004), that occurs when using the arts in health care and …

Cloning And Analysis Of Putative Collagenases Of The U32 Family In Streptococcus Mutans And Streptococcus Agalactiae (Group B Streptococci), Valerie Carson

USF Tampa Graduate Theses and Dissertations

Analysis of the genomic sequences of Streptococcus mutans UA159 and Group B Streptococcus (GBS) strains Streptococcus agalactiae NEM316 and S. agalactiae 2603V/R indicated the presence of two putative collagenase genes in each organism. smcol1 from S. mutans was previously cloned and analyzed and the results indicated that the enzyme belonged to the U32 family of collagenases/peptidases. This enzyme shares homology with the prtC of Porphyromonas gingivalis, one of the principal examples of the U32 family of peptidases. Considering the potential role of these enzymes in the pathogenicity of P. gingivalis (periodontitis or gum disease), GBS (premature rupture of the amniochorionic …

Functional Topology And Regulation Of Endothelial Nitric Oxide Synthase And Associated Caveolar Components, Brenda R. Flam

USF Tampa Graduate Theses and Dissertations

The discovery of nitric oxide (NO) as the endothelial-derived relaxing factor has led to significant research on NO and the proteins involved in its function, generation, location and regulation. Synthesis of NO by blood vessel endothelial cells results from the enzymatic oxidation of arginine by endothelial nitric oxide synthase (eNOS) resulting in the formation of equimolar amounts of NO and citrulline. Citrulline is sequentially recycled to arginine by successive reactions involving the enzymes argininosuccinate synthase (AS) and argininosuccinate lyase (AL), respectively.

eNOS activity has been shown to be regulated by post-translational modifications including dynamic phosphorylation on multiple serine/threonine and tyrosine …

Tyrosinase-Like Activity Of Several Alzheimer’S Disease Related And Model Peptides And Their Inhibition By Natural Antioxidants, Kashmir Singh Juneja

USF Tampa Graduate Theses and Dissertations

Neurodegenerative diseases are associated with loss of neurons ultimately leading to a decline in brain function. Alzheimer's disease (AD) is considered one of the most common neurodegenerative disorders that affects 16 million people worldwide. The cause of the disease remains unknown, although significant evidence proposes the amyloid Beta-peptide (A-Beta) as a potential culprit. The binding of Cu2+ by the soluble fragments of A-Beta have shown to form Type-3 copper centers and catalyze the oxidation of catechol-containing neurotransmitters. Furthermore, the use of flavonoids as antioxidants to slow or inhibit the neurotransmitter oxidation has suggested further health benefits with their consumption. A …
