A Complete Approach To Predict Biodistribution Of Nanomaterials Within Animal Species From In-Vitro Data, Edward Price Jan 2019

A Complete Approach To Predict Biodistribution Of Nanomaterials Within Animal Species From In-Vitro Data, Edward Price

Electronic Theses and Dissertations

Smart drug-design for antibody and nanomaterial-based therapies allows for optimization of drug efficacy and more efficient early-stage pre-clinical trials. The ideal drug must display maximum efficacy at target tissue sites, but to track and predict distribution to these sites, one must have a mechanistic understanding of the kinetics involved with the individual cells of the tissue itself. This process can be tracked through biological simulations coupled with in-vitro approaches, which result in a rapid and efficient in-depth understanding of drug transport within tissue vasculature and cellular environment. As a result, it becomes possible to predict drug biodistribution within live animal …

Solution Of Linear Ill-Posed Problems Using Overcomplete Dictionaries, Pawan Gupta Jan 2019

Solution Of Linear Ill-Posed Problems Using Overcomplete Dictionaries, Pawan Gupta

Electronic Theses and Dissertations

In this dissertation, we consider an application of overcomplete dictionaries to the solution of general ill-posed linear inverse problems. In the context of regression problems, there has been an enormous amount of effort to recover an unknown function using such dictionaries. While some research on the subject has been already carried out, there are still many gaps to address. In particular, one of the most popular methods, lasso, and its variants, is based on minimizing the empirical likelihood and unfortunately, requires stringent assumptions on the dictionary, the so-called, compatibility conditions. Though compatibility conditions are hard to satisfy, it is well …

Nanoplasmonics In Two-Dimensional Dirac And Three-Dimensional Metallic Nanostructure Systems, Alireza Safaei Jan 2019

Nanoplasmonics In Two-Dimensional Dirac And Three-Dimensional Metallic Nanostructure Systems, Alireza Safaei

Electronic Theses and Dissertations

Surface plasmons are collective oscillation of electrons which are coupled to the incident electric field. Excitation of surface plasmon is a route to engineer the behavior of light in nanometer length scale and amplifying the light-matter interaction. This interaction is an outcome of near-field enhancement close to the metal surface which leads to plasmon damping through radiative decay to outgoing photons and nonradiative decay inside and on the surface of the material to create an electron-hole pair via interband or intraband Landau damping. Plasmonics in Dirac systems such as graphene show novel features due to massless electrons and holes around …

Variation In Prospecting Behavior And Drivers Of Post-Fire Habitat Preference Among Juvenile Florida Scrub-Jays, David Sherer Jan 2019

Variation In Prospecting Behavior And Drivers Of Post-Fire Habitat Preference Among Juvenile Florida Scrub-Jays, David Sherer

Electronic Theses and Dissertations

Florida Scrub-Jays (Aphelocoma coerulescens, FLSJ; federally Threatened) are cooperatively breeding birds endemic to Florida and dependent on fire-maintained xeric oak scrub. FLSJs are year-round residents, highly territorial, and rarely disperse far from their natal territory. Lifetime reproductive success is highest among individuals breeding in early-successional habitat, usually less than 9 to 10 years post-fire. However, because scrub burns infrequently such early-successional, high-quality habitat is extremely limited and competition for it as breeding space is likely intense. Because some birds live long enough to experience habitat succession, FLSJs also occupy later-successional overgrown scrub, even though both survival and fecundity decline. Although …

Role Of Tnfα Antagonists And Genetic Polymorphisms In Modulating Susceptibility To Mycobacterial Infection Among Patients With Crohn's Disease, Ahmad Qasem

Electronic Theses and Dissertations

Tumor Necrosis Factor alpha antagonists (anti-TNFα) have been extensively used for Crohn's disease (CD) treatment. Even though they may control CD symptoms initially, treatment response varies among patients, which seems to depend on single nucleotide polymorphisms (SNPs) in TNFα receptors superfamily 1A and 1B (TNFRSF1A/B). Most importantly, M. tuberculosis infection has been strongly associated with these medications, but no studies have elucidated the effects of anti-TNFα on CD associated with MAP (Mycobacterium avium subspecies paratuberculosis; a possible causative agent of CD, and closely related to M. tuberculosis). Here, we investigated the effects of recombinant inflammatory cytokines and anti-TNFα therapeutics on …
