Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer Jan 2007

Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer

USF Tampa Graduate Theses and Dissertations

The extracellular environment of the central nervous system (CNS) through which neuritic processes must traverse during development or after injury is complex, and may vary from stabile conditions to a milieu favorable for neural plasticity and growth. The extracellular space in the CNS accounts for about 20% of brain volume and is composed of aggregating complexes of several different extracellular matrix (ECM) molecules. The ECM supports neural networks and acts as a barrier for neurite extention, depending on the type of molecules involved and the various signals they induce. One mechansim that may produce an environment favoring plasticity is the …

An Experimental Study Of Pro-Dieting And Anti-Dieting Psychoeducational Messages: Effects On Immediate And Short-Term Psychological Functioning And Weight Control Practices In College Women, Megan Roehrig

USF Tampa Graduate Theses and Dissertations

While dieting is relatively normative in our society, it is controversial within the fields of eating disorders and obesity. Dieting for weight loss has been touted by the obesity prevention field as a solution to the growing obesity epidemic, yet a body of research in the eating disorders field has also implicated it in the etiology and maintenance of eating pathology. Thus, a divergence in approaches toward dieting has emerged, with both prodieting and anti-dieting messages being recommended. Little is known, however, about the impact of these two types of messages on immediate and short-term psychological functioning and weight control …

Modeling The Dynamics Of Tritrophic Population Interactions, Andrew Paul Gutierrez, Johann Baumgärtner Jan 2007

Modeling The Dynamics Of Tritrophic Population Interactions, Andrew Paul Gutierrez, Johann Baumgärtner

All Peer-Reviewed Publications

Introduction Increasingly, population modeling and systems analysis are being used to examine the complex issues that are at the heart of CP/IPM (crop production and integrated pest management) and biological control. The design of economically sound and sustainable crop management strategies requires a thorough understanding of the whole production system including arthropod pests, pathogens, and weeds. More than three decades ago, Huffaker and Croft (1976) stressed the need to rely on systems analysis and interdisciplinary collaboration to accomplish this task. Soon the question arose as to how mathematical techniques employed in the analysis of physical systems could be adapted to …

Enterobacter Sakazakii: An Emerging Microbe With Implications For Infant Health, N. R. Mullane, B. Healy, Ciara Walsh, C. Iversen, P. Whyte, P. G. Wall, T. Quinn, Seamus Fanning

Articles

Enterobacter sakazakii (E. sakazakii) is an opportunistic pathogen and the aetiological agent in rare but life-threatening cases of meningitis, necrotizing enterocolitis, and sepsis in infants. Among infants, those at greatest risk are neonates (<28 >days), particularly those born prematurely or of low birth weight (g). Consumption of contaminated powdered infant formula (PIF) has been epidemiologically linked with cases of infection. Contamination can occur during the manufacturing process or during postmanufacture reconstitution of formula. Development of rapid, sensitive and specific detection methods will facilitate manufacturers efforts to reduce the occurrence of E. sakazakii in the final powdered product. Furthermore, since PIF …

Efficacy Of Steamer Jet-Injection As Alternative To Chlorine In Fresh-Cut Lettuce, Ana Belen Martin-Diana, Daniel Rico, Catherine Barry-Ryan, Jesus Maria Frias, Gary Henehan, J. Barat

Articles

Short-time steam processing was used as an alternative to chlorine (100 mg L−1) in sanitising fresh-cut lettuce. Quality (pH, water content, colour, potential browning, browning-related enzymes and texture), safety (mesophilic counts) and antioxidant markers (ascorbic and carotenoids) were monitored in lettuce stored for 10 days at 4 °C. The steam treatment produced a shocking effect on lettuce metabolism, showing a significant (p < 0.05) reduction in respiration (from day 3 to 7) and a partial inactivation of browning-related enzymes. Both effects were reflected in a significant reduction of browning. From a safety point of view, steam treatment kept the mesophilic load as low as chlorine treatment, and significantly lowers than the water control. However, antioxidant content, especially ascorbic acid but also carotenoids in a lower degree, showed a reduction compared with chlorine-treated samples. Despite the lower visual browning in steam-treated samples, the sensory panel scored similar values of acceptability and fresh appearance for both samples similarity.

Contract Law And Distribution In The Age Of Welfare Reform, Daniela Caruso Jan 2007

Contract Law And Distribution In The Age Of Welfare Reform, Daniela Caruso

Faculty Scholarship

This Article tracks the ongoing adaptation of U.S. contract law to the 1990s’ contraction of the welfare state. Some courts strive to compensate for the shortage of welfare services and to pursue redistributive goals. This Article provides examples of this trend and then analyzes the non-linear relation between doctrines, judicial redistribution, and welfare politics in both case law and scholarship. Finally, this Article discusses the role of socially sensitive judicial discourse in light of contemporary welfare politics and explains its continuing importance.

Custom-Made Total Contact Insoles And Prefabricated Functional Diabetic Insoles: A Case Report, J Paton, E Stenhouse, R Jones, G Bruce

School of Health Professions

Insoles are commonly prescribed to offload the mechanical stresstransmitted to the plantar tissues of the foot. Traditionally, thecustom-made total-contact insole (TCI) is favoured over itsprefabricated counterpart. The introduction of a new prefabricateddiabetic insole (A Algeo Ltd, Liverpool) designed to modify footbiomechanics may offer an instant, low-cost, clinically-effectivealternative. We report on a comparison of the two insoles in thecase of a 54-year-old woman with type 2 diabetes and peripheralneuropathy, presenting with ulceration overlying the thirdmetatarsal region. The F-scan in-shoe pressure measurement system(TEKSCAN) provided an objective measure of effect.
