AUIQ Complementary Biological System

Alzheimer's disease (AD) is increasingly recognized as a multisystem neurodegenerative disorder involving oxidative stress and neuroinflammation beyond classical hippocampal pathology. The hypothalamus, a key regulator of metabolic and neuroendocrine homeostasis, remains comparatively underexplored in experimental AD models. This study investigated the effects of aqueous Annona muricata seed extract (SSE) on hypothalamic oxidative injury in an aluminium chloride (AlCl₃)-induced Alzheimer's disease–like model in Wistar rats. Adult Wistar rats of both sexes were randomly assigned to five groups (n = 5): control, AlCl₃ (100 mg/kg), SSE alone (200 mg/kg), AlCl₃ + SSE, and AlCl₃ + donepezil (10 …

Perturbations To Horizontal Gnss Position Time Series By Atmospheric Lee Waves In The San Bernardino Valley, California, Walter Szeliga, Logan Grey

All Faculty Scholarship for the College of the Sciences

Anomalous systematic position offsets have been noted in GNSS time series from a variety of locations around the globe. In many regions, these time series anomalies coincide with the presence of cloud streets in visible satellite imagery, implicating atmospheric lee waves as the source of the position offsets. We report here on seasonal anomalous position offsets from the San Bernardino Basin of southern California that occur during clear skies. Modeling of the troposphere on days with anomalous positions shows the presence of atmospheric lee waves. Ray tracing through these tropospheric models suggests that atmospheric lee waves create low elevation perturbations …

Voice And Pain: Representations Of Disability In Adaptations Of “The Little Mermaid”, Ace Molloy

Departmental Honors & Graduate Capstone Projects

Hans Christian Andersen’s 1837 story, “The Little Mermaid,” is a popular fairy tale that has been adapted several times by writers, filmmakers, and game developers. It is one of the few fairy tales with explicit portrayals of disability; the mermaid in the tale is nonspeaking and experiences chronic pain, as well as being a mermaid—a nonnormative figure who is aligned with disability. This paper looks at the ways that the mermaid is portrayed in literary, film, and new media adaptations from a disability-justice perspective. Examining multiple representations of the character, I argue that while feminist adaptations erase her disability and …

Intravenous Dexamethasone Administration Prior To Spinal Anesthesia, Virginia Nelsen, Nancy Westbrook

Group: Samford University Moffett & Sanders School of Nursing

Dexamethasone is a potent synthetic glucocorticoid that reduces nitric oxide- mediated vasodilation, increases sympathetic activity, elevates catecholamine levels, and increases vascular sensitivity to vasopressors. A one-time dose of 8mg was most often administered by researchers. The timing of administration varied from two hours prior to immediately before spinal placement. The peak effect of dexamethasone occurs 45 to 60 minutes after administration which suggests that immediate dosing may not provide maximal benefit. The most common adverse effects of steroids include hyperglycemia, immunosuppression, delirium, and perineal itching. Overall, the available literature supports the short-term safety of a single dose of dexamethasone in …

Neurobiological Pathways Underlying Brain Tumor Progression: Basis For Oncogenicity And Opportunities For Immunotherapeutic Intervention, Carrie E. Andrews, Jenny Zilberberg, Raul Perez-Olle, David Andrews, Mark A. Exley

Department of Neurosurgery Faculty Papers

Both primary and metastatic brain tumors rely on signals from the surrounding environment for their survival and progression. In particular, the most common and lethal brain cancer, glioblastoma (GBM), derived from glial cells (astrocytes or microglia), has been shown to integrate into synaptic networks and to receive paracrine signals from neighbouring tumor microenvironment (TME) cells. There is increasing evidence that metastatic disease in the brain exhibits similar behavior. The TME both maintains malignant cells and is maintained by them, a process that relies on cancer stem cells (CSCs). These stem cells and their signaling mechanisms, including in the case of …
