One such group of tools are fluorescent probes, molecules that emit detectable signals when stimulated by an excitation source. Incorporating fluorescent conjugates for clinical purposes would enable direct usage for the diagnosis, detection, or treatment of diseases. The development of specific targeting agents is feasible due to the number of nanomaterials and biological products that contain fluorophores. Specific targeting agents can target a particular region of interest, such as a cancerous tumor for removal or vital nerve structure for avoidance …

Establishing A Generalized Qualifying Autoclitic Repertoire In Children With Autism Spectrum Disorder, Todd M. Owen

Theses & Dissertations

Autoclitics are secondary verbal operants that are controlled by a feature of the conditions that evoke a primary verbal operant (e.g., tact, mand). Among the types described by Skinner, qualifying autoclitics extend, negate, or assert a speaker’s primary verbal response and modify the intensity or direction of the listener’s behavior. In the only study to date on teaching qualifying autoclitics, Howard and Rice (1988) established generalized autoclitics that indicated weak stimulus control (e.g., “like a [primary tact]”) with four typically developing preschool children. However, generalization to newly acquired tacts was limited. In Experiment 1, we extended Howard and Rice to …

The Role Of Calprotectin In T-Lymphocyte Driven Inflammation In A Mouse Model Of Psychological Trauma, Cassandra Moshfegh

Theses & Dissertations

Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder that affects nearly 45 million Americans. This mental disorder is characterized by behavioral symptoms such as learned helplessness, hyperarousal, withdrawal, and flashbacks. The deleterious effects of PTSD are far-reaching and go beyond behavioral dysfunction, as these individuals are at a three-fold higher risk of comorbid inflammatory diseases. Autonomic, metabolic, and cardiovascular diseases plague these individuals later in their lifetime, however, the mechanistic link connecting psychological trauma to this systemic peripheral immunological dysfunction remains elusive. T-lymphocyte-induced inflammation plays a significant role in all these disease pathologies. Previous work from our laboratory demonstrated …

Regulation Of Pancreatic Cancer Progression By Micronutrients, Chunbo He

Theses & Dissertations

Cancer cells rely on altered metabolism to support their uncontrolled proliferation under harsh conditions. Understanding the mechanisms of how metabolic alterations support tumor growth may provide a way to enhance current therapies. Vitamins are micronutrients that our body needs in small quantities but are essential for health maintenance. A number of metabolic processes relevant to cancer initiation and progression are also regulated by vitamins. Here, our studies showed that pancreatic ductal adenocarcinoma (PDAC) cells display an aberrant metabolism of vitamin B6 (VB6) to support their fast proliferation. VB6 was highly demanded and rapidly metabolized by PDAC cells. Depletion of VB6 …

Metagenome-Wide Associations And Metabolic Modeling To Predict The Biomarkers For Colorectal Cancer, Nagavardhini Avuthu

Theses & Dissertations

Colorectal cancer (CRC) is the most common malignancy and the second most common cause of cancer-related deaths in the world. It is a multifactorial disease mediated by genetic, environmental, and lifestyle factors. Over time, the accumulation of genetic and epigenetic changes results in the activation of oncogenes and deactivation of tumor suppressor genes in the colon and rectal region which finally leads to tumor development. The gut microbiome is the main factor linking the effects of diet and environmental factors to host metabolism. Several studies showed the dysbiosis of gut microbiota in CRC patients with an increased proportion of pathogenic …

Innate Immunity In The Pathobiology And Treatment Of Infectious And Neurodegenerative Diseases, Mai Mostafa

Theses & Dissertations

Mononuclear phagocytes (MPs; monocytes, macrophages, and dendritic cells) are the governors of innate immunity which is the body’s first line of defense against microbial pathogens. They act beneficial or detrimental. They are crucial for an effective non-specific immune response to invading pathogens by engulfing, destroying, then eliciting an adaptive specific immune response. Given their pivotal functions in the host immune defense, studying MP immune responses in disease is paramount important for understanding disease pathobiology and uncovering therapeutic strategies.
