The Combined Effects Of Physical Exercise And Cognitive Training On Gait Speed And Primary Motor Cortex Metabolism In Individuals With Mild Cognitive Impairment: A 1h-Mrs Analysis, Jack Thomas Emsey Elkas

Mild cognitive impairment (MCI) is a transitional stage before dementia. Altered gait in MCI has been associated with progression to dementia. Using magnetic resonance spectroscopy, a relationship between primary motor cortex (M1) neurochemistry and dual task gait speed has been reported in MCI. Interventional research suggests exercise, cognitive training, and vitamin D supplementation may benefit MCI, yet the combined effect of these treatments on gait speed and M1 metabolism is unknown. Participants with MCI (N=75) were assigned to one of five intervention arms and dual task cost on gait speed and M1 metabolism was assessed before and five months after …

Hyperpolarized 129xe Magnetic Resonance Imaging Of Radiation-Induced Lung Injury, Ozkan Doganay
Electronic Thesis and Dissertation Repository
Lung cancer is the largest contributor to cancer-related mortality worldwide. Only 20% of stage III non-small cell lung cancer patients survive after 5-years post radiation therapy (RT). Although RT is an important treatment modality for lung cancer, it is limited by Radiation-Induced Lung Injury (RILI). RILI develops in two phases: (i) the early phase (days-weeks) referred to radiation pneumonitis (RP), and (ii) the late phase (months). There is a strong interest in early detection of RP using imaging to improve outcomes of RT for lung cancer. This thesis describes a promising approach based on 129Xe gas as a contrast …
Interpretation Of Mutations, Expression, Copy Number In Somatic Breast Cancer: Implications For Metastasis And Chemotherapy, Stephanie Dorman
Interpretation Of Mutations, Expression, Copy Number In Somatic Breast Cancer: Implications For Metastasis And Chemotherapy, Stephanie Dorman

Breast cancer (BC) patient management has been transformed over the last two decades due to the development and application of genome-wide technologies. The vast amounts of data generated by these assays, however, create new challenges for accurate and comprehensive analysis and interpretation. This thesis describes novel methods for fluorescence in-situ hybridization (FISH), array comparative genomic hybridization (aCGH), and next generation DNA- and RNA-sequencing, to improve upon current approaches used for these technologies. An ab initio algorithm was implemented to identify genomic intervals of single copy and highly divergent repetitive sequences that were applied to FISH and aCGH probe design. FISH …

Methotrexate And Cardiovascular Events, Alpesh Shah
Electronic Thesis and Dissertation Repository
We conducted a systematic review and meta-analysis to assess the association of MTX with cardiovascular morbidity, cardiovascular mortality and all-cause mortality in patients with autoimmune disease. Our primary outcome was incident cardiovascular events. After screening 13,479 citations, we identified a total of 30 eligible studies. We synthesized adjusted risk estimates using a random effects model. MTX was significantly associated with a 25% reduction in cardiovascular events (pooled RR: 0.75, 95% CI: 0.65, 0.86, I2: 11%), a 55% reduction in cardiovascular mortality (0.45, 95% CI: 0.26, 0.80, I2: 33%) and a 40% reduction in all-cause mortality (0.60, …

With aging, keratinocytes have diminished proliferative capacity resulting in atrophic skin with reduced barrier function. This investigation evaluates the effect of daily topical applications of a novel high-molecular weight hyaluronan cream (HA-PE) on keratinocyte renewal and epidermal thickness. Unmodified hyaluronan and HA-PE were mixed separately into a vehicle cream. Each topical formulation was applied daily onto the shaved backs of aged female C57BL6 mice. Full-thickness biopsies of treated skin were obtained for analysis of keratinocyte proliferation, keratinocyte differentiation, and local inflammation at days 1, 5, and 10 of cream application. In addition, a cardiac puncture was performed for serum C-reactive …

Sepsis is characterized by a severe systemic inflammatory response to infection that is associated with high morbidity and mortality despite optimal care. Invariant natural killer T (iNKT) cells are potent regulatory lymphocytes that can produce pro- and/or anti-inflammatory cytokines, thus shaping the course and nature of immune responses; however, little is known about their role in sepsis. We demonstrate here that patients with sepsis/severe sepsis have significantly elevated proportions of circulating iNKT cells in their peripheral blood, as compared to non-septic patients. We therefore investigated iNKT cells in mice with intra-abdominal sepsis (IAS). Our data show that iNKT cells are …

Targeted Sirna Delivery Methods For Rnai-Based Therapies, Di Chen
Electronic Thesis and Dissertation Repository
RNAi has great potential in future therapeutics as it has the ability to regulating many disease-related genes. However, many barriers prevent practical applications. To overcome the barriers, the specific targeting, efficient delivery system, the validated gene and the potent siRNA sequence are all vital important. The studies throughout this thesis have been focued on examining the validation of three RNAi therapies for two different disease models: allergic contact dermatitis and melanoma. For allergic contact dermatitis, I developed and tested a novel topical delivery system for siRNAs targeting TNFα (siTNFα) and MyD88 siRNA (siMyD88). While siRNAs applied without the transdermal enhancer …

The development of screening approaches to identify novel affinity ligands has paved the way for a new generation of molecular targeted nanomedicines. To identify novel targeting ligands, several studies have demonstrated the advantages in screening one-bead-one-compound (OBOC) libraries. Conventional methods typically bias the display of the target protein to ligands during the screening process. We have developed an unbiased multiplex ‘beads on a bead’ strategy to isolate, characterize, and validate high affinity ligands from OBOC libraries. In addition, due to the advantages associated with screening OBOC libraries directly against living cells, we sought to combine cell-based screen methods with automated …
