Neural-Glial-Vascular Interactions In Human Outer Retina, Deepayan Kar Jan 2023

Neural-Glial-Vascular Interactions In Human Outer Retina, Deepayan Kar

All ETDs from UAB

The outer retinal metabolic ecosystem is a complex interplay among photoreceptors, RPE and blood supply from the retinal and choroidal microcirculation. Breakdown of any component of this ecosystem has detrimental effects and can lead to cellular dysfunction. For example, in age-related macular degeneration a major cause of vision loss in older adults, breakdown of this metabolic unit has severe structural and functional implications. Thus, every feature and component of this ecosystem seems to be optimized to protect non-replicating, terminally differentiated cells from being damaged. Remarkably, much of the cellular and subcellular organization of this system is available for observation in …

Synthesis, Characterization, And Evaluation Of A Bionanomatrix And Antibiotic-Releasing Liposomes On Osseointegration, Vascularization, Inflammation, And Antibacterial Efficacy, Benjamin Kade Estep

All ETDs from UAB

Percutaneous osseointegrated prostheses (POP) implants combat the multitude of issues and limitations of contemporary prosthetic sockets/limbs, including range of motion, comfort/fit, irritation, gait, and osseoproprioception. However, POP implants lack long-term clinical success; specifically, several risks exist at the bone-implant interface, including superficial/deep infections, inflammation, poor vascularization, and inadequate osseointegration, resulting in implant loosening over time and ultimately removal of the implant. The goal of this thesis is to evaluate a multifunctional, nitric oxide-releasing bionanomatrix incorporated with antibiotic-releasing liposomes on osseointegration, inflammation, vascularization/angiogenesis, and bacterial infection. We successfully synthesized the bionanomatrix, and the antibiotic-releasing liposomes readily encapsulated the antibiotics. The antibiotic-releasing …

Effect Of Different Supporting Die Materials And Crown Thicknesses On The Fracture Load Of Monolithic 3y-Tzp Zirconia And Lithium Disilicate Crowns, Akram Mohamed Mohamed Gad Sayed Ahmed

All ETDs from UAB

Background: Conventionally, the strength of dental materials used for fixed restorations is measured using specimens of simplified geometry (i.e bars or discs). There is value in measuring the strength of these materials in their anatomic geometry (i.e crowns) under clinically relevant loading conditions. One advantage of performing the so-called crown fracture test is that the material may benefit from its ability to be strengthened by its bond to a tooth-mimicking die. When performing a crown fracture test, the ideal die material is natural tooth structure. However, the variability in natural tooth anatomy and microstructure makes the use of a standardized, …

Accuracy Of Ancestry Estimation In Forensic Anthropology: An Examination Of Select Nonmetric Methods, Mackenzie Miller Jan 2023

Accuracy Of Ancestry Estimation In Forensic Anthropology: An Examination Of Select Nonmetric Methods, Mackenzie Miller

All ETDs from UAB

A goal of forensic anthropology is to aid in identifying unidentified human remains, often by creating a biological profile. An important piece of this profile is an ancestry estimate, and methodological accuracy is taken seriously. Traditional typological nonmetric methods of ancestry are heavily critiqued for being subjective and lacking scientific rigor in analysis. In addition, these methods are noted for conflating morphological traits with specific ancestral categories, ignoring the reality of continuous human variation. To combat this, scholars have proposed morphoscopic nonmetric methods as an alternative because they retain the accessibility popularized by typological methods but add a layer of …

Reframing The Study Of Peace Through The Lens Of Complex Adaptive Systems, Nick Mauro Jan 2023

Reframing The Study Of Peace Through The Lens Of Complex Adaptive Systems, Nick Mauro

All ETDs from UAB

Many researchers studying peace have posited that peace is a system. Although this approach has recently included steps to address complexity, current models have not sufficiently integrated their approach with complex adaptive systems to produce functionally dynamic models. Rather, current models describe peace systems as teleological and linear, which creates closed systems that do not incorporate feedback from the environment and, therefore, do not identify adaptive processes. Furthermore, these models reflect the state of a system, an arrangement of constituent parts in specific contexts, rather than capturing the complexity that is necessary for describing a dynamic system. To address these …

Characterizing A Unique Oprm1 Expressing Neuronal Population In The Rat Nucleus Accumbens, Emma Andraka

All ETDs from UAB

Opioid-related overdose deaths have increased drastically in the past three decades, and especially since the beginning of the COVID-19 pandemic, due to the addictive, analgesic, and euphoric properties of the drugs. To produce these effects, opioids bind to the mu opioid receptor (MOR) in GABAergic neurons. The MOR is encoded by the Oprm1 gene and is expressed in multiple brain regions that regulate reward and motivation, such as the nucleus accumbens (NAc). Previous studies of Oprm1 knockdown in medium spiny neurons (MSNs) of the mouse NAc have shown that these neuronal populations are involved in reinforcing reward-context pairing as well …

Does Perceived Emotional Invalidation Moderate The Relation Between Occupational Stress And Mental Health Outcomes In Law Enforcement Officers?, Sahar Jaafar M.S.; M.A.

Selected Full Text Dissertations, 2011-

Police officers are exposed to operational stressors while on duty, including child abuse, domestic violence, car crashes, and homicides (Jetelina et al., 2020). Repeated exposure to these stressors is associated with the development of mental illness (Jetelina et al., 2020). Organizational stressors, including lack of support/validation, demand, job pressure, administrative/organizational pressure, and long working hours, may be an even greater source of stress for police officers (Purba & Demou, 2019). Exposure to such organizational stressors can result in psychological distress, burnout, and suicidal ideation (Purba & Demou, 2019). However, there is a dearth of research on invalidation and the role …
