Thermal Inequities In Public Parks And Open Spaces In Los Angeles Determined By Remote Sensing, Ashley Agatep, Joshua B. Fisher, Kainani Tacazon, Ambar Rivera, Rossmery Zayas, Reginald Archer, Juan Carlos Ruiz Malagon, Jason A. Douglas

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Urban heat island (UHI) effects are amplified by disparities in community-level cooling infrastructure—such as urban public parks and open spaces (PPOS)—with the most severe impacts occurring in communities that lack sufficient city-wide cooling resources. We found that the underserved community of South Los Angeles, as compared to their neighboring West Los Angeles counterparts, suffers a double burden of inequitable (1) access to and (2) absence of cooling materials and surfaces within these spaces, resulting in significantly hotter temperatures. Identifying these inequities requires high-resolution temporal and spatial mapping of surface temperatures, which has been previously limited. In this community-based participatory research …

Prephiral Bacterial Infectious Agent Triggers Neuroinflammatory Responses And Neurobehavioral Impairment In Wild-Type Mice, Hadeer Atalah

Theses and Dissertations

Neurodegenerative diseases, including Alzheimer's and Parkinson's, present an increasing global challenge, with chronic neuroinflammation identified as a principal factor alongside genetic, environmental, and infectious influences (Boyd et al., 2022).  Epidemiological data associate bacterial infections with a 40% heightened risk of Parkinson's disease; however, the mechanisms—especially the direct connection between peripheral sepsis and the silent onset of central nervous system pathology absent acute meningitis—are inadequately investigated (Smeyne et al., 2021), particularly concerning common pathogens like Klebsiella pneumoniae in high-burden areas such as Egyptian ICUs, where it constitutes 30% of cases (Alkompoz et al., 2023). This study filled the gap by creating …

Investigating Tau Pathology In The Retina And Anterior Segment Structures Of The Eye In A 3-Nitropropionic Acid–Induced Tauopathy Mouse Model, Mohamed Sayed Ahmed Abdel-Kader Qasem

Theses and Dissertations

Background and Objectives: Alzheimer's disease, the most prevalent neurodegenerative disorder in older adults, is characterized by accumulation of hyperphosphorylated tau and amyloid-beta (Aβ) plaques in the central nervous system. Given the retina's shared embryological origin with the brain, its direct neural connectivity via the optic nerve, and similarities in vasculature and age-related degeneration patterns, retinal pathology may serve as an early, non-invasive biomarker for Alzheimer's disease. This study employed 3-nitropropionic acid (3NP) as a pathway-specific tauopathy model driven by mitochondrial dysfunction. The study particularly aimed to investigate whether retinal and corneal tau pathology reflects underlying tau-related neurodegeneration triggered by …

Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.
