The optimal hemodynamic management of traumatic spinal cord injury (tSCI) is not well established. We performed a systematic review and meta-analysis of patients with acute tSCI to assess the role of lumbar cerebrospinal fluid drainage (CSFD) and to identify factors predictive of neurological improvement. Three studies involving 46 patients with acute tSCI, lumbar drain placement with CSFD, and available pre- and post-intervention American Spinal Injury Association (ASIA) Impairment Scale or International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) motor scores were identified. One study was analyzed separately (Cohort A) using ASIA grade because post-intervention ISNCSCI motor scores were …

Carbonation For Enhancement Of Fine Recycled Aggregate Applied To Mortar, Henrique Comba Gomes, Augusto Cesar Da Silva Bezerra, Conrado De Souza Rodrigues, Flavia Spitale Jacques Poggiali, Boksun Kim

School of Engineering, Computing and Mathematics

Some of the challenges faced by the construction industry related to sustainability are the generation of construction and demolition waste (CDW), environmental impacts caused by the demand for natural aggregates, and associated carbon (CO₂) emissions. One potential solution is recycling CDW as recycled aggregates (RA). Though, RA generally performs poorly compared to natural aggregates (NA) in concretes. Researchers suggest that CO₂ curing via accelerated carbonation may improve the properties of RA. However, further investigation is needed to understand the impact of CO₂ curing on mortar made with fine recycled aggregates (FRA). This study explores the effects …

A Federated Approach To Scalable And Trustworthy Financial Fraud Detection, Yaser Alhasawi, Aljwhrh Abdalaziz Almtrf, Muhammad Asad

School of Engineering, Computing and Mathematics

Financial fraud remains a critical challenge for digital banking, requiring detection solutions that ensure both scalability and data privacy. Traditional centralized approaches face limitations due to security risks and system bottlenecks. This paper proposes FedFraud, a novel federated learning (FL) framework that detects fraudulent transactions without sharing raw data. FedFraud introduces two key innovations: (i) a trust-aware client aggregation mechanism that assigns weights based on update reliability and (ii) an asynchronous communication protocol enabling clients to contribute updates independently. Evaluated on the Credit Card Fraud Detection dataset under a nonidentically distributed (non-IID) data setting where client data distributions differ significantly, …

Clientelism And The Erosion Of Legislative Oversight: Examining The House Of Representative (Dewan Perwakilan Rakyat, Dpr) Role Under President Joko Widodo (2014–2024), Muhammad Tri Andika Kurniawan, Suseela Chandra Devi

Jurnal Wacana Politik

This article investigates the weakening of legislative oversight by The House of (Dewan Perwakilan Rakyat, DPR) during President Joko Widodo’s tenure from 2014 to 2024. Despite the expanded constitutional authority granted to the DPR following the 1998 political reforms, the quality of oversight function has diminished markedly in the Jokowi era. Drawing on theoretical and empirical literature, the article argues that this erosion is not solely the result of institutional shortcomings or inadequate reform, but is primarily driven by pervasive clientelistic relationships between the president and party elites. Such clientelism entrenches political patronage, enabling the executive to exert significant influence …

A Picture Paints A Thousand Words: Understanding How People Conceptualise Autism Through Images, Gray Atherton, Emily Dawson, Andrea Piovesan, Lauren Hawksworth-Quill, Liam Cross

School of Psychology

Conceptions of autism and neurodiversity vary widely, with differing views on how they are portrayed in contemporary culture. Although autism scholars have long advocated for greater involvement of autistic individuals in knowledge creation, meaningful co-production between autistic stakeholders, researchers, and the broader community remains limited. To explore differences in autism knowledge between autistic and non-autistic people, we used a qualitative method called visual elicitation. We invited the public to upload an image they felt represented autism and explain their choice. Through thematic analysis of these images and their accompanying descriptions, we identified three key themes highlighting how autism is currently …

Structural Analysis Of Pseudomonas Phage Dev Virion-Associated Rna Polymerase (Gp71), James Scherer

All ETDs from UAB

DEV is a Pseudomonas aeruginosa bacteriophage part of a newly reclassified genus called Schitoviridae. This group of bacteriophages is also referred to as “N4-like” phages, after the prototypical Escherichia coli phage N4, originally isolated from sewage water in 19661. N4, and other phages in the group, contain a large, virion-associated RNA polymerase (vRNAP). This vRNAP is vital to the proliferation of the phage, as it performs the transcription of the early gene products and potentially acts as a motor that helps eject the viral genome into the host bacteria. In DEV, the vRNAP is also known as gene product 71 …

Patterns Of Resilience, Patterns Of Tragedy: Perspectives From Inside And Outside To Theorize Beneficial Interventions Serving Urban African American Youth Struggling With Community Violence, Katherine Tyson Mccrea, Kevin Miller, Amzie Moore, Heather L. Watson

Social Work: School of Social Work Faculty Publications and Other Works

Community violence, defined as violence perpetrated in community as opposed to home settings, is a salient social problem, causing terror and tragedy, especially in urban, low-income communities of color. Interventions supporting youth struggling with community violence have been insufficiently studied and theorized, especially from strengths-focused, culturally relevant standpoints in the context of contemporary social policies. This paper outlines psychodynamic theoretical models for services that have been developed via participatory research and provided for 19 years for over 1000 youth. Then, to understand how youth make use of the programs from an “inside” perspective, four intensive case examples are described. From …

Investigating How Evolution Has Affected The Neuroanatomy Of Adult Astyanax Mexicanus, Peter Igwilo

Electronic Theses and Dissertations

The topology of the brain is highly conserved across phyla, yet the evolutionary processes driving anatomical divergence remain poorly understood. The fish Astyanax mexicanus, which exists in both surface- and cave-dwelling morphs within the same species, provides a powerful model for studying brain evolution. While previous studies have focused on larvae, imaging adult brains has been challenging due to their size and opacity. This study overcame these limitations using tissue clearing, light sheet imaging, and computational analysis to generate a comprehensive adult brain atlas. Using nuclear staining and antibody labeling, brain-wide 3D maps were created to compare regional size, shape, …

Faculty, Staff and Student Publications

Alzheimer's disease (AD) is a neurodegenerative disease characterized by the accumulation of misfolded proteins in the brain. Recently, the impact of blood components in the progression of this disease has come to attention. This study investigates the effects of infusing blood from young and old wild-type mice into transgenic mice that model AD brain amyloidosis. Impaired memory and Aβ accumulation were observed in mice infused with blood from old donors. A proteomic analysis in the brain of these mice identified alterations in components related to synaptogenesis and the endocannabinoid system. The α2δ2 protein, associated with neuronal calcium regulation, was validated …

Loss Of Ptdss1 In Tumor Cells Improves Immunogenicity And Response To Anti-Pd-1 Therapy, Jielin Liu, Shelley Herbrich, Sreyashi Basu, Yulong Chen, Ashwat Nagarajan, Swetha Anandhan, Sangeeta Goswami, Liangwen Xiong, Baoxiang Guan, Padmanee Sharma

Faculty, Staff and Student Publications

PTDSS1 (phosphatidylserine synthase 1) encodes an enzyme that facilitates production of phosphatidylserine (PS), which mediates a global immunosuppressive signal. Here, based on in vivo CRISPR screen, we identified PTDSS1 as a target to improve anti-PD-1 therapy. Depletion of Ptdss1 in tumor cells increased expression of interferon-γ (IFN-γ)-regulated genes, including B2m, Cxcl9, Cxcl10, and Stat1, even in the absence of IFN-γ stimulation in vitro. Loss of Ptdss1 in tumor cells also led to increased expression of MHC-I, enhanced cytotoxicity of CD8+ T cells, and increased frequency of an iNOS+ myeloid subset. A gene signature derived from the …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Posterior capsule opacification (PCO) is a fibrotic complication of cataract surgery caused by aberrant repair of residual lens cells. It remains unclear how the lens injury response shifts toward a pathological repair process. Here, we performed a transcriptional analysis of two major pro-fibrotic pathways, the TGF-β superfamily and Wnt signaling pathways to determine how they are differentially regulated during regenerative wound healing versus fibrosis in a lens injury model. For these studies, RNA sequencing was performed on an ex vivo lens explant system that models post-surgical healing within regenerative and fibrotic microenvironments, from 0 to 3 days post-injury. Fibrotic conditions …

Targeting Kinin B1r Attenuates Hypertension Through At1r-Dependent Mechanisms, Drew Theobald, Riley N. Bessetti, Yumei Feng Earley, Eric Lazartigues, Karen Litwa, Srinivas Sriramula

School of Medicine Faculty Publications

BACKGROUND: Neurogenic hypertension is chronically high blood pressure that is initiated and maintained through excessive sympathetic nervous system activity and has been associated with increased B1R (kinin B1 receptor) activation. We previously reported a central role for B1R in mediating inflammatory pathways in the development of deoxycorticosterone acetate salt hypertension. Additionally, we identified a causal relationship between B1R expression after Ang II (angiotensin II) stimulation, and that B1R can mediate the bidirectional interaction between neuroinflammation and oxidative stress. However, whether there are any interactions between AT1R (Ang II-type I receptor) and B1R, and if B1R can mediate the effects of …

In Vivo Efficacy Of A Broad-Spectrum Antiviral Combination Against Yellow Fever In A Hamster Model, Abbie E. Weight, Hunter Stanger, Robert J. Geraghty, Laurent F. Bonnac, Justin G. Julander

Animal, Dairy, and Veterinary Science Student Research

Yellow fever virus (YFV) recurrently causes severe outbreaks in tropical regions of South America and Africa and an average of 30 to 40 thousand deaths worldwide each year. An effective vaccine is available but the coverage of the population in countries at risk is not optimal. No antivirals are currently approved for YFV treatment. Herein, we describe the evaluation of 6-MMPr, a de-novo-purine-nucleotide biosynthesis inhibitor, as a potentiator for enhanced activity of the broad-spectrum antiviral drug favipiravir in a hamster model of yellow fever. Administration of 6-MMPr was well-tolerated and a combination of favipiravir and 6-MMPr did not cause …

Integrating Identity-Based Identification Against Adaptive Adversaries In Federated Learning, Jakub Kacper SzeląG, Ji-Jian Chin, Lauren Ansell, Sook-Chin Yip

School of Engineering, Computing and Mathematics

Federated Learning (FL) has recently emerged as a promising paradigm for privacy-preserving, distributed machine learning. However, FL systems face significant security threats, particularly from adaptive adversaries capable of modifying their attack strategies to evade detection. One such threat is the presence of Reconnecting Malicious Clients (RMCs), which exploit FL’s open connectivity by reconnecting to the system with modified attack strategies. To address this vulnerability, we propose the integration of Identity-Based Identification (IBI) as a security measure within FL environments. By leveraging IBI, we enable FL systems to authenticate clients based on cryptographic identity schemes, effectively preventing previously disconnected malicious clients …
