Introduction: A cognitive theory of culture as socially distributed cultural models has proven useful in research. Cultural models exist in two forms: the model shared by individuals in a social group, and individual versions of that model modified by personal experience. In previous research we documented a shared cultural model of substance use risk among a general population sample in urban Brazil. Here we examine how this model is distributed among persons under treatment for substance use/misuse and the implications for perceived and self-stigma.

Methods: A convenience sample of 133 persons under treatment rated the influence of risk factors for …

APC Fund

Over 50,000 people die annually from opioid overdoses in the United States leading to what has become known as the “opioid epidemic.” This is of heightened concern in states like Alabama that experience higher rates of overall drug use and overdose deaths. Thus, it is increasingly important for college students in Alabama to learn about how the opioid epidemic is affecting their communities. Previous studies have demonstrated that engaging non-majors in innovative active-learning oriented pedagogies like service-learning can enhance their understanding and awareness about contemporary societal issues. Despite its pedagogical potential, the impact of opioid-related service-learning, particularly for non-majors, continues …

Associations of HLA class II alleles with genital chlamydial infection outcomes have been reported, especially HLA DQB1*06. However, the potential role of DQB1*06 in influencing reinfection risk has still not been established. The purpose of this study was to determine whether the association of DQB1*06 with chlamydia reinfection was impacted by any other nearby HLA class II variants that were also associated with reinfection. We used next-generation sequencing to map HLA class II variants spanning the HLA-DQ and -DR loci. DQB1*06 as well as DQB1*04 were confirmed as significant predictors of chlamydia reinfection, when controlling for age and percent African …

Introduction. Proximal tibia physeal fractures in children are not very common but can be dangerous because they can harm popliteal fossa structures, especially the popliteal artery. Popliteal artery injuries (PAI) are most commonly the result of trauma to the lower extremity, including blunt force, hyperextension injuries, complex fractures, and knee dislocations that can compromise popliteal neurovascular structures. Case Presentation. A 14-year-old boy presents to the emergency department after being transferred from an outside hospital 24 hours after a left lower extremity hyperextension injury. Radiographs demonstrated a Salter-Harris III proximal tibia fracture with posterior displacement. ABIs were deferred due to palpable …

Antiviral Treatment Of Maternal And Congenital Cytomegalovirus (Cmv) Infections, Swetha Pinninti, Suresh Boppana

APC Fund

Human Cytomegalovirus (HCMV) is a ubiquitous member of the Herpesviridae family, responsible for the most common congenital viral infection—congenital Cytomegalovirus (cCMV) infection. While a majority of HCMV infections in children and adults are asymptomatic, HCMV is well known to cause severe infections in the immunocompromised individual and maternal infections with variable long-term sequelae after maternal–fetal transmission with primary or nonprimary infections. HCMV seroprevalence and cCMV incidence vary by geographic area and demographic characteristics like race and socioeconomic status. While cCMV birth prevalence ranges from 0.2% to 6% in different parts of the world, it is influenced by regional HCMV seroprevalence …

Streptococcus pneumoniae (Spn) resides in the nasopharynx where it can disseminate to cause disease. One key Spn virulence factor is pneumococcal surface protein A (PspA), which promotes survival by blocking the antimicrobial peptide lactoferricin. PspA has also been shown to mediate attachment to dying epithelial cells in the lower airway due to its binding of cell surface-bound mammalian (m)GAPDH. Importantly, the role of PspA during colonization is not well understood. Wildtype Spn was present in nasal lavage elutes collected from asymptomatically colonized mice at levels ∼10-fold higher that its isogenic PspA-deficient mutant (ΔpspA). Wildtype Spn also …

There are diverse types of health care systems, policies and health care organizations existing in health care delivery arrangements across the world (1). Two distinct influential groups of professionals have emerged as a result. They are: 1. Macro-level, population-oriented heath policy planners and analysts (health policy professionals–HPP) and 2. More micro-level, institutionally-oriented managers and organizational leaders and executives (health management professionals–HMP). As the old idiom goes, “one can't see the forest for the trees.” Are HPP professionals at such “altitude” that they have a clear vision of the forest, but fail to understand how things are on the …

APC Fund

The central circadian regulator within the suprachiasmatic nucleus transmits time of day information by a diurnal spiking rhythm driven by molecular clock genes controlling membrane excitability. Most brain regions, including the hippocampus, harbor similar intrinsic circadian transcriptional machinery, but whether these molecular programs generate oscillations of membrane properties is unclear. Here, we show that intrinsic excitability of mouse dentate granule neurons exhibits a 24-h oscillation that controls spiking probability. Diurnal changes in excitability are mediated by antiphase G-protein regulation of potassium and sodium currents that reduce excitability during the Light phase. Disruption of the circadian transcriptional machinery by conditional …


Effectiveness Of The Invisalign System For Deep Bite Correction, Jerry D. Spillers Iii Jan 2023

Effectiveness Of The Invisalign System For Deep Bite Correction, Jerry D. Spillers Iii

All ETDs from UAB

Objective: To assess the dental and skeletal changes resulting from correction of a deep bite using Invisalign (Align Technology, Santa Clara, CA, USA).Methods: This is a retrospective case series study which analyzed pre and post treatment cephalograms for 37 adult deep bite patients. Each patient was treated by one, experi-enced clinician using the same treatment protocols. Nineteen variables, ten linear and nine angular. The Wilcoxon analysis was used to determine if there was a significant dif-ference in pre and post treatment variables. Results: Statistically significant differences (P<0.05) occurred for 14 of 19 variables. These include a decrease in Overjet (-0.97 mm), decrease in overbite (-4.07 mm), extru-sion of the upper first molar (0.47 mm), intrusion of the upper incisor (-0.67mm), extru-sion of the lower second molar (1.01 mm), lower first molar (1.20 mm), lower second premolar (1.70 mm), and lower first premolar (1.74 mm), intrusion of the lower incisor (-1.88 mm), proclination of lower incisor, (4.09 ̊), and increase in SN-MP (0.54 mm). A decrease in anterior occlusal plane (AOP) was also statistically significant. Conclusions: Invisalign is an effective treatment modality for correcting dental deep bites through posterior extrusion and anterior intrusion. Minimal skeletal changes are seen when correcting deep bites with Invisalign.


Aberrant Signal Transduction Of Neuronal Injury: Trauma And Toxicology, Alan Umfress Jan 2023

Aberrant Signal Transduction Of Neuronal Injury: Trauma And Toxicology, Alan Umfress

All ETDs from UAB

Neurological injuries occur in epidemic proportions worldwide. Neuronal injuries are events resulting in damage to the central nervous system (CNS) that impair neurological function. Subsequent impairments in neuronal function can be rapid, existing immediately after injury, or progressive and chronic impairments that persist for the lifetime of the survivor. CNS injury constitutes a broad class of environmental and pathophysiological insults ranging from blunt-force trauma to the brain or spinal cord, to acute ischemic and hemorrhagic strokes, and insults resultant from neurotoxic agents. While divergent in initial cause, many of these insults share underlying pathophysiological outcomes including excitotoxic cell signaling, neuroinflammation, …


Impact Of Arthroplasty Surgery On The Local Immune Composition Of The Knee Joint And Implications For The Periprosthetic Joint Infection, Kyle H. Cichos Jan 2023

Impact Of Arthroplasty Surgery On The Local Immune Composition Of The Knee Joint And Implications For The Periprosthetic Joint Infection, Kyle H. Cichos

All ETDs from UAB

The overall risk of infection after total knee arthroplasty (TKA) has not improved over the past 20 years, remaining 10-40 times greater than the risk of infection of a native knee. Despite extensive research into periprosthetic joint infection (PJI), little is known about the synovial fluid immune homeostasis of the native knee joint and how TKA surgery itself impacts the local immune composition. While many postulate a role for cartilage in maintaining this immune homeostasis, the exact method in which it contributes remains elusive. Therefore, in this dissertation I have investigated the synovial fluid changes occurring in the knee joint …

Cell cycle is a universal necessity of cellular life and impacts nearly every process within the cell. However, despite over one hundred years of research, there still remain questions concerning the mechanisms and regulation of eukaryotic cell cycle. From the beginning, viruses have informed our knowledge of cell cycle. Many key regulators such as the E2F transcription factors, Src kinase, and p53 were originally discovered while studying the interactions between viruses and the cell. Herein, we continue the investigation of viral interactions with cell cycle machinery by researching an RNA virus and a DNA virus. These viruses, human coronavirus OC43 …

The Molecular And Structural Basis Of B Cell Epitope Targeting In Transplant Rejection, John T. Killian Jr Jan 2023

The Molecular And Structural Basis Of B Cell Epitope Targeting In Transplant Rejection, John T. Killian Jr

All ETDs from UAB

HLA-reactive antibodies (HLA-Abs) to mismatched polymorphic HLA molecules are one of the major barriers to successful organ transplantation. However, key knowledge gaps remain surrounding the immunology of the anti-HLA B cell response in transplant rejection. This lack of understanding regarding the phenotype and specificity of the anti- HLA B cell response means that the field cannot develop optimal therapies to treat B-cell mediated donor-specific responses and that it lacks the tools to optimally match donors and recipients to prevent rejection events. Therefore, this dissertation aimed to explore the clinical factors associated with the formation of donor-specific antibodies and the molecular …

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 …
