Since it can circulate within the food chain, has a long biological half-life and can bio-accumulate, it has the potential to induce detrimental health effects linked to toxicity, cancer and chronic diseases.

In recent years progress has been made to dissect and understand the molecular mechanisms underlying the effects of cadmium exposure. However, few studies have focused on investigating potential protective and/or defense mechanisms naturally applied by cells upon initial exposure, prior to any damage or toxic …

Structure-Function Studies Of Self- Assembling Flagellin Proteins Fromsalmonella Typhimurium And Aquifex Pyrophilus, Venkata Raghu Ram Malapaka

Dissertations

The eubacterial flagellum is a complex structure with an elongated extracellular filament that is primarily composed of a single protein termed flagellin. The highly conserved N-and C- termini of flagellin are important in its export and assembly, whereas the middle "hypervariable" region is highly variable in size across different species and is largely dispensable. InSalmonella typhimurium phase 1 flagellin (FliC), this hypervariable region encodes two solvent-exposed D2 and D3 domains. The functional role of this knob-like structural feature in motility remains unclear. The structural and physiological role of the hypervariable region in flagellar assembly, stability and cellular motility was investigated. …

So You Think It's Inclusion…Think Again: A Quantitative Analysis Of Stakeholder Perceptions In Community Youth Organizations, Mary Mcallister Shea Edd

Dissertations

Over the last thirty years, a cultural transformation has occurred in public schools as students with disabilities have slowly moved from segregated sites and special day classes to more inclusive classroom environments. Although this change has largely been driven by legislative mandate, including the requirement that students be supported in the least restrictive environment possible, the benefits of inclusion have been exceedingly well documented in the literature. Unfortunately, the inclusiveness seen within schools has not extended to the provision of out-of-school programs, and as a result, sixteen years after the passage of the Americans with Disabilities Act, children with disabilities …
