Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic
Electronic Thesis and Dissertation Repository
Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …
Comorbid Metabolic Syndrome And Prodromal Alzheimer's Disease In A Rat Model, Nadezda Ivanova
Comorbid Metabolic Syndrome And Prodromal Alzheimer's Disease In A Rat Model, Nadezda Ivanova
Electronic Thesis and Dissertation Repository
Metabolic syndrome (MetS), the development of which is associated with high-caloric Western diet intake, represents a risk factor for mild cognitive impairment (MCI) and Alzheimer’s disease (AD) and appears to contribute to AD progression when MetS and AD are comorbid. The interaction between AD and MetS might be through white matter inflammation, since white matter abnormalities and inflammation are important early events in the etiopathogenesis of both diseases. In these investigations, the effect of a high-caloric diet (HCD), to induce metabolic disturbances, on white matter neuroinflammation and cognitive function was investigated in a transgenic (TG) rat model of prodromal AD …
Scaffold Design Considerations For Soft Tissue Regeneration, Madeleine M. Di Gregorio
Scaffold Design Considerations For Soft Tissue Regeneration, Madeleine M. Di Gregorio
Electronic Thesis and Dissertation Repository
Tissue engineering has emerged as a promising strategy for the replacement of degenerating or damaged tissues in vivo. Also known as regenerative medicine, integral to this therapeutic strategy is biomimetic scaffolds and the biomaterial structural components used to form them. In this study, three different biomaterial scaffolds for tissue engineering applications were fabricated: three-dimensional reverse embedded collagen scaffolds, polymer fusion printed polycaprolactone (PCL) scaffolds, and electrospun gelatin scaffolds. Three-dimensional collagen and PCL scaffolds promoted human adipose-derived stem/stromal cell (ASC) spreading, proliferation, and fibronectin deposition in vitro. Secondly, this study investigated the efficacy of exogenous galectin-3 delivery as a …
Monocyte Mri Relaxation Rates Are Regulated By Extracellular Iron And Hepcidin, Praveen S.B Dassanayake
Monocyte Mri Relaxation Rates Are Regulated By Extracellular Iron And Hepcidin, Praveen S.B Dassanayake
Electronic Thesis and Dissertation Repository
Monocytes are an important immune cell type in chronic inflammatory conditions like atherosclerosis and heart failure. The increase in number of monocytes released to the peripheral blood circulation, the differentiation of monocytes to macrophages, and the presence of different macrophage subpopulations during pro- and anti-inflammatory stages of tissue injury may provide markers for monitoring inflammation. In particular, changes in monocyte iron metabolism during an inflammatory response may increase the possibility of tracking these immune cells non-invasively using magnetic resonance imaging (MRI). When secretion of the polypeptide hormone hepcidin is stimulated during inflammation, it binds the iron export protein ferroportin (FPN) …
Brain-Specific And Systemic Inflammatory Response Following Repetitive Concussive Impact In A Mouse Model, So Young Eo
Brain-Specific And Systemic Inflammatory Response Following Repetitive Concussive Impact In A Mouse Model, So Young Eo
Electronic Thesis and Dissertation Repository
Concussion is the most common form of mild traumatic brain injury (mTBI). TBI resolution is modulated by neuroinflammation, which is augmented by the infiltration of innate immune cells from the circulation. Peripheral, myeloid immune cells not only invade neural tissues but other organs as well causing local inflammation and tissue damage, known as systemic inflammatory response syndrome. Here, I assessed the temporal and anatomical nature of the neural and systemic cellular inflammatory response to repetitive, mTBI in a 3-hit mouse model of concussion. The results showed significant microglial activity, accumulation of peripheral myeloid cells and prominent axonal damage post-injury. The …
Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, James J. Armstrong
Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, James J. Armstrong
Electronic Thesis and Dissertation Repository
Dysregulated wound healing contributes to most currently unanswered ophthalmological morbidity. Opacification and structure altering contractures compromise the delicate ocular anatomy upon which ocular function and healthy vision are reliant. Glaucoma filtration surgery, corneal stromal injury, proliferative vitreoretinopathy and age-related macular degeneration are major contributors to ocular morbidity – all with myofibroblast transdifferentiation and pathognomonic scarring activity at their core.
This thesis aims to revaluate the means by which dysregulated ocular wound healing is combated with evidence describing a novel strategy to mitigate its effects. A translational approach was used. An initial retrospective analysis of over ten thousand glaucoma surgeries found …
