Sustaining Planetary Health: Putting A Stop To Ecosystem Decline, Unsustainable Practices And Associated Human Suffering, George Atisa, Parita Shah

Public Affairs and Security Studies Faculty Publications

The natural environment is considered a free resource for humans to utilize, but doing so comes with costs associated with how it is used, e.g., degraded ecosystems, fragmented landscapes, pollution and climate change. These negative effects make humans’ place on Earth inhospitable. The inherent challenge is the inability to connect or simply deny the association of the poor health currently experienced by people to the cumulative degradation of various ecosystems. A degraded ecosystem is not just a loss to a diverse planetary system or a waste in its own right, but because of the complex relationships involved, it becomes a …

Habitat Loss Exacerbates Pathogen Spread: An Agent-Based Model Of Avian Influenza Infection In Migratory Waterfowl, Shenglai Yin, Yanjie Xu, Mingshuai Xu, Mart C M De Jong, Mees Rs Huisman, Andrea Contina, Herbert H T Prins, Zheng Y X Huang, Willem F. De Boer

School of Integrative Biological & Chemical Sciences Faculty Publications

Habitat availability determines the distribution of migratory waterfowl along their flyway, which further influences the transmission and spatial spread of avian influenza viruses (AIVs). The extensive habitat loss in the East Asian-Australasian Flyway (EAAF) may have potentially altered the virus spread and transmission, but those consequences are rarely studied. We constructed 6 fall migration networks that differed in their level of habitat loss, wherein an increase in habitat loss resulted in smaller networks with fewer sites and links. We integrated an agent-based model and a susceptible-infected-recovered model to simulate waterfowl migration and AIV transmission. We found that extensive habitat loss …

Statistical Analysis Methods Applied To Early Outpatient Covid-19 Treatment Case Series Data, Eleftherios Gkioulekas, Peter A. Mccullough, Vladimir Zelenko

School of Mathematical & Statistical Sciences Faculty Publications

When confronted with a public health emergency, significant innovative treatment protocols can sometimes be discovered by medical doctors at the front lines based on repurposed medications. We propose a statistical framework for analyzing the case series of patients treated with such new protocols, that enables a comparison with our prior knowledge of expected outcomes, in the absence of treatment. The goal of the proposed methodology is not to provide a precise measurement of treatment efficacy, but to establish the existence of treatment efficacy, in order to facilitate the binary decision of whether the treatment protocol should be adopted on an …

Could Cultures Determine The Course Of Epidemics And Explain Waves Of Covid-19?, Md Salman Rahman

Theses and Dissertations

Coronavirus Disease (COVID-19), caused by the SARS-CoV-2 virus, is an infectious disease that quickly became a pandemic spreading with different patterns in each country. Travel bans, lockdowns, social distancing, and non-essential business closures caused significant economic disruptions and stalled growth worldwide in the pandemic’s first year. In almost every country, public health officials forced and/or encouraged Nonpharmaceutical Interventions (NPIs) such as contact tracing, social distancing, masks, and quarantine. Human behavioral decision-making regarding social isolation significantly impedes global success in containing the pandemic. This thesis focuses on human behaviors and cultures related to the decision-making of social isolation during the pandemic. …

School of Medicine Publications

Tuberculosis (TB), considered an ancient disease, is still killing one person every 21 seconds. Diagnosis of Mycobacterium tuberculosis (M.tb) still has many challenges, especially in low and middle-income countries with high burden disease rates. Over the last two decades, the amount of drug-resistant (DR)-TB cases has been increasing, from mono-resistant (mainly for isoniazid or rifampicin resistance) to extremely drug resistant TB. DR-TB is problematic to diagnose and treat, and thus, needs more resources to manage it. Together with+ TB clinical symptoms, phenotypic and genotypic diagnosis of TB includes a series of tests that can be used on different specimens to …

Associative Learning In The Monodelphis Domestica Utilizing The Cpa Paradigm, Joseph Caleb Cantu

Theses and Dissertations

This study aims to investigate associative learning in the Monodelphis domestica by utilizing the conditioned place aversion paradigm (CPA). The Monodelphis domestica has been used as an animal model for research in multiple fields; however, there is still little information regarding associative learning or utilizing a CPA paradigm.

Improved Guidelines Of Indoor Airborne Transmission Taking Into Account Departure From The Well-Mixed Assumption, Jorge S. Salinas, K. A. Krishnaprasad, ‪Nadim Zgheib, S. Balachandar

Mechanical Engineering Faculty Publications

The well-mixed assumption has been widely used in predicting the spread of infectious diseases in indoor spaces. It is to be expected that a perfect well-mixed state will not be achieved in an indoor space at any reasonable level of ventilation. This work evaluates the well-mixed assumption by comparing the theory with results from large eddy simulations. The robustness of the well-mixed theory is established by comparing at four different levels. The comparison also points out systematic departures in pathogen concentration which can be accurately accounted for with an easily implementable correction factor to quantities such as cumulative exposure time. …

Antibody-Mediated Lilrb2-Receptor Antagonism Induces Human Myeloid-Derived Suppressor Cells To Kill Mycobacterium Tuberculosis, Vipul K. Singh, Arshad Khan, Yitian Xu, Sunny Mai, Licheng Zhang, Abhishek Mishra, Blanca I. Restrepo, Ping-Ying Pan, Shu-Hsia Chen

School of Medicine Publications

Tuberculosis is a leading cause of death in mankind due to infectious agents, and Mycobacterium tuberculosis (Mtb) infects and survives in macrophages (MФs). Although MФs are a major niche, myeloid-derived suppressor cells (MDSCs) are an alternative site for pathogen persistence. Both MФs and MDSCs express varying levels of leukocyte immunoglobulin-like receptor B (LILRB), which regulate the myeloid cell suppressive function. Herein, we demonstrate that antagonism of LILRB2 by a monoclonal antibody (mab) induced a switch of human MDSCs towards an M1-macrophage phenotype, increasing the killing of intracellular Mtb. Mab-mediated antagonism of LILRB2 alone and its combination with a pharmacological blockade …

Modeling The Impact Of Climate Change On Cervid Chronic Wasting Disease In Semi-Arid South Texas, Md Rafiul Islam, Ummugul Bulut, Teresa Patricia Feria-Arroyo, Michael G. Tyshenko, Tamer Oraby

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Chronic wasting disease (CWD) is a spongiform encephalopathy disease caused by the transmission of infectious prion agents. CWD is a fatal disease that affects wild and farmed cervids in North America with few cases reported overseas. Social interaction of cervids, feeding practices by wildlife keepers and climate effects on the environmental carrying capacity all can affect CWD transmission in deer. Wildlife deer game hunting is economically important to the semi-arid South Texas region and is affected by climate change. In this paper, we model and investigate the effect of climate change on the spread of CWD using typical climate scenarios. …

Human M1 Macrophages Express Unique Innate Immune Response Genes After Mycobacterial Infection To Defend Against Tuberculosis, Arshad Khan, Kangling Zhang, Vipul K. Singh, Abhishek Mishra, Priyanka Kachroo, Tian Bing, Jong Hak Won, Eder Ledezma-Campos, Genesis P. Aguillón-Durán, Blanca I. Restrepo

School of Medicine Publications

Mycobacterium tuberculosis (Mtb) is responsible for approximately 1.5 million deaths each year. Though 10% of patients develop tuberculosis (TB) after infection, 90% of these infections are latent. Further, mice are nearly uniformly susceptible to Mtb but their M1-polarized macrophages (M1-MΦs) can inhibit Mtb in vitro, suggesting that M1-MΦs may be able to regulate anti-TB immunity. We sought to determine whether human MΦ heterogeneity contributes to TB immunity. Here we show that IFN-γ-programmed M1-MΦs degrade Mtb through increased expression of innate immunity regulatory genes (Inregs). In contrast, IL-4-programmed M2-polarized MΦs (M2-MΦs) are permissive for Mtb proliferation and exhibit reduced …

Bromodomains In Human-Immunodeficiency Virus-Associated Neurocognitive Disorders: A Model Of Ferroptosis-Induced Neurodegeneration, Adonis Sfera, Karina G. Thomas, Christina V. Andronescu, Nyla Jafri, Dan O. Sfera, Sarvin Sasannia, Carlos Zapata-Martin Del Campo, Jose E. Campo Maldonado

School of Medicine Publications

Human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) comprise a group of illnesses marked by memory and behavioral dysfunction that can occur in up to 50% of HIV patients despite adequate treatment with combination antiretroviral drugs. Iron dyshomeostasis exacerbates HIV-1 infection and plays a major role in Alzheimer’s disease pathogenesis. In addition, persons living with HIV demonstrate a high prevalence of neurodegenerative disorders, indicating that HAND provides a unique opportunity to study ferroptosis in these conditions. Both HIV and combination antiretroviral drugs increase the risk of ferroptosis by augmenting ferritin autophagy at the lysosomal level. As many viruses and their proteins …

Human Macrophages Exhibit Gm-Csf Dependent Restriction Of Mycobacterium Tuberculosis Infection Via Regulating Their Self-Survival, Differentiation And Metabolism, Abhishek Mishra, Vipul K. Singh, Chinnaswamy Jagannath, Margaret Sunitha Selvaraj, Selvakumar Subbian, Blanca I. Restrepo, Marie-Claire Gauduin, Arshad Khan

School of Medicine Publications

GM-CSF is an important cytokine that regulates the proliferation of monocytes/macrophages and its various functions during health and disease. Although growing evidences support the notion that GM-CSF could play a major role in immunity against tuberculosis (TB) infection, the mechanism of GM-CSF mediated protective effect against TB remains largely unknown. Here in this study we examined the secreted levels of GM-CSF by human macrophages from different donors along with the GM-CSF dependent cellular processes that are critical for control of M. tuberculosis infection. While macrophage of different donors varied in their ability to produce GM-CSF, a significant correlation was observed …

Emergency Preparedness: Perceptions Of People With Disabilities, Lidia Adamina Fonseca

Theses and Dissertations

The prevalence of emergencies and disasters has increased over the past decade which has caused cities, states and countries to routinely develop emergency preparedness and management plans (Turk, 2016). Although these demands have increased, individuals with disabilities have been less represented in the development of the plans (Timmons, 2017; Turk, 2016). According to The World Bank Disaster Risk Management Report (2020), disasters (e.g., infectious disease outbreaks such as COVID-19, hurricanes, earthquakes, industrial accidents.) and post-disaster consequences have increased over recent years.

Although individuals with disabilities have become more aware of emergency preparedness and its importance, researchers have noted that there …

Non-Negative Discriminative Data Analytics, Md Imrul Kaish

Theses and Dissertations

Due to advancements in data acquisition techniques, collecting datasets representing samples from multi-views has become more common recently (Jia et al. 2019). For instance, in genomics, a lymphoma patient’s dataset may include data on gene expression, single nucleotide polymorphism (SNP), and array Comparative genomic hybridization (aCGH) measurements. Learning from multiple views about the same objective, in general, obtains a better understanding of the hidden patterns of the data compared to learning from a single view data. Most of the existing multi-view learning techniques such as canonical correlation analysis (Hotelling et al. 1936) and multi-view support vector machine (Farquhar et …

Structures And Regulations Of Translation Initiation Factors In Pseudomonas Aeruginosa Protein Biosynthesis To Develop New Potential Antimicrobial Agents, Nicolette Valdez

Theses and Dissertations

Pseudomonas aeruginosa is a Gram-negative, multidrug resistant bacterium that has been recognized as the prominent cause of nosocomial infections. Untreated acute and chronic infections associated with P. aeruginosa can develop into other diseases such as pneumonia, otitis externa, and osteomyelitis. P. aeruginosa infections commonly affect immunocompromised individuals such as cystic fibrosis, cancer, and burn patients. The misuse and overuse of antibiotics has contributed to the increased antibiotic resistance in P. aeruginosa and thus has led to an unmet need for discovery of novel antibiotic candidates. Protein biosynthesis is an essential metabolic process occurring in all bacteria and a validated target …
