Study Of The Egfr, Src And Stat3 Pathway In Pancreatic Cancer, Soumya Jaganathan
Study Of The Egfr, Src And Stat3 Pathway In Pancreatic Cancer, Soumya Jaganathan
Electronic Theses and Dissertations
Cancer is associated with many molecular aberrations that support the malignant phenotype. In that regard, aberrant activation of epidermal growth factor receptor (EGFR), Src, and signal transducer and activator of transcription 3 (Stat3) occur concurrently in pancreatic cancer and are implicated in the disease phenotype. Notwithstanding, increasing evidence indicates that therapies that target only EGFR or Src are rather ineffective in modulating the cancer phenotype. The poor therapeutic outcome of the monotherapies targeting EGFR or Src may in part be due to the increased incidence of signaling cross-talks among aberrant signaling pathways in cancer. Molecular details of the signaling integration …

Identification Of Novel Antimalarials From Marine Natural Products For Lead Discovery, Stephenie M. Alvarado
Electronic Theses and Dissertations
An estimated 500 million cases of malaria occur each year. The increasing prevalence of drug resistant strains of Plasmodium in most malaria endemic areas has significantly reduced the efficacy of current antimalarial drugs for prophylaxis and treatment of this disease. Therefore, discovery of new, inexpensive, and effective drugs are urgently needed to combat this disease. Marine biodiversity is an enormous source of novel chemical entities and has been barely investigated for antimalarial drug discovery. In an effort to discover novel therapeutics for malaria, we studied the antimalarial activities of a unique marine-derived peak fraction library provided by Harbor Branch Oceanographic …

Sensation Rebuilt: Carnal Ontology In Levinas And Merleau-Ponty, Tom Sparrow
Sensation Rebuilt: Carnal Ontology In Levinas And Merleau-Ponty, Tom Sparrow
Electronic Theses and Dissertations
The phenomenological approaches to embodiment presented by Levinas and Merleau-Ponty cannot provide an adequate account of bodily identity because their methodological commitments forbid them from admitting the central role that sensation plays in the constitution of experience. This neglect is symptomatic of their tradition's suspicion toward sensation as an explanatory concept, a suspicion stemming from Kant's critique of empiricist metaphysics and Husserl's critique of psychologism and objectivism. By contrast, I suggest that only with a robust theory of sensation can the integrity of the body and its relations be fully captured. I therefore develop--contra Kant and Husserl's idealism--a realist conception …

Electronic Theses and Dissertations
This dissertation presents and evaluates a method of managing spoken dialog interactions with a robust attention to fulfilling the human user’s goals in the presence of speech recognition limitations. Assistive speech-based embodied conversation agents are computer-based entities that interact with humans to help accomplish a certain task or communicate information via spoken input and output. A challenging aspect of this task involves open dialog, where the user is free to converse in an unstructured manner. With this style of input, the machine’s ability to communicate may be hindered by poor reception of utterances, caused by a user’s inadequate command of …
Text Versus Verbal Real-Time Feedback During Simulation-Based Training Of Higher-Order Cognitive Skills, C L. Fiorella
Text Versus Verbal Real-Time Feedback During Simulation-Based Training Of Higher-Order Cognitive Skills, C L. Fiorella
Electronic Theses and Dissertations
A crucial component of instructional design for simulation-based training systems involves optimizing the presentation of complex material in order to maximize knowledge acquisition and application. One approach toward facilitating the learning of this complex information is to instantiate instructional strategies within the training systems themselves. However, there are few established guidelines in place which are meant specifically for real-time guidance strategies within simulation-based environments. Consequently, this study aims to apply findings from the literature on instructional information presentation to drive decisions for how to most effectively provide real-time feedback during training of simulated decision-making tasks. Research has shown that presenting …
An Interval Based Approach To Model Input Uncertainty In Discrete-Event Simulation, Ola Batarseh
An Interval Based Approach To Model Input Uncertainty In Discrete-Event Simulation, Ola Batarseh
Electronic Theses and Dissertations
The objective of this research is to increase the robustness of discrete-event simulation (DES) when input uncertainties associated models and parameters are present. Input uncertainties in simulation have different sources, including lack of data, conflicting information and beliefs, lack of introspection, measurement errors, and lack of information about dependency. A reliable solution is obtained from a simulation mechanism that accounts for these uncertainty components in simulation. An interval-based simulation (IBS) mechanism based on imprecise probabilities is proposed, where the statistical distribution parameters in simulation are intervals instead of precise real numbers. This approach incorporates variability and uncertainty in systems. In …

A Peptide-Based Platform For Displaying Antibodies To Engage T Cells, Ying Zheng
A Peptide-Based Platform For Displaying Antibodies To Engage T Cells, Ying Zheng
Electronic Theses and Dissertations
This study investigated a strategy by which antibodies were displayed on a gel-like substance to engage T cells. The substance, a peptidic composite, was characterized in vitro and explored as an injectable system in vivo. The composite consists of two amphiphilic peptides, AEAEAKAKAEAEAKAK (referred to as "EAK") and AEAEAKAKAEAEAKAKHHHHHH ("EAKH6"). Spectroscopic analysis showed the two peptides integrated into a single structure. Prior to combination, conformational analysis revealed that EAKH6 adopts a mixed alpha-helix/bata-strand conformation. In the presence of EAK, EAKH6 exists predominantly in a beta;-strand conformation. Using nickel-bound horseradish peroxidase as a probe, the composite of EAK-EAKH6 was found to …
