Symmetry And Scale: The Precise Engineering Of Chitosan-Based Polyhedral For The Delivery Of Therapeutic Materials At The Nanoscale, Ahmed. J. Jasim, Noor Malik Saadoon

AUIQ Technical Engineering Science

Preparation of chitosan-based drug delivery carriers requires converting linear polysaccharide chains into individual 3D objects. By building on the natural structural properties of chitin-based polymers, in addition to control the geometry of organically derived raw material from feedstock to submicron polyhedral or spherical dimensions. This geometric change is governed by a surface area-to-volume ratio that maximizes the exposure of the therapeutic payload to the external environment. The approach centres on the development of such carriers using ion-complexation and emulsification methodologies, which involve electrostatic cross-linking of ion-binding pairs to define an impenetrable boundary separating a liquid from a solid phase. Critical …

Synergistic Microbiome-Peptidome Therapeutics: Exploring Lactobacillus Reuteri Dsmz 17648 And Stem Cell-Derived Peptides For Immunomodulation And Tissue Repair Across Diseases, Hasan M. Agha, Mohammed A. Abdalqader, Abdullah Asad Siddiqui, Shafiq Aazmi, Jantson Hoh, Oh Chin Kin Michelle, Sabaa M. Agha, Amjad Abdulhadi Mohammed, Muneer Mohammed Saleh Alsayadi

AUIQ Complementary Biological System

Chronic inflammatory and degenerative disorders are driven by interconnected immune dysregulation, metabolic instability, epithelial barrier disruption, and impaired tissue repair, limiting the durability of conventional single-target therapies. The global rise in chronic inflammatory, metabolic, and age-related degenerative diseases underscores an urgent need for multi-dimensional therapeutic strategies that move beyond isolated molecular targets. Despite rapid advances in microbiome science and regenerative medicine, these fields have largely evolved in parallel, with limited integration at the translational level. Emerging evidence identifies the gut microbiome as a central regulator of systemic immunometabolic homeostasis through microbial metabolites, barrier integrity modulation, and immune-cell education. In parallel, …

Sharing The Gold With The Mountain: A Proposed Quasi-Property Doctrine For Health Data Compensation, Taylor Col

Journal of Technology Law & Policy

This Note provides a legal answer to the moral question of whether a person should be compensated for lucrative health data that was collected from them. The moral question is examined through the lens of various doctrines in property, privacy, intellectual property, and ethics, in light of landmark cases concerning biomaterials and genetic information. A new doctrine for health data compensation is proposed, based on quasi-property and borrowing elements from equity, intellectual property, and profit-sharing. The proposed doctrine is evaluated by applying it to a hypothetical commercialization of one person’s health data via a precision medicine product.

Python Hunting: How Laws That Protect The Everglades From The Invasive Burmese Python, Including Eradication Programs, Can Inform The Regulation Of Objects Controlled By Artificial Intelligence, Kerri Lynn Stone, Joshua Stone

Journal of Technology Law & Policy

This Article explores the surprisingly apt analogy between the Burmese python problem in the Florida Everglades and abandoned objects that are controlled by artificial intelligence (AI). With few natural predators, the invasive Burmese python, which was likely introduced to the Everglades through abandonment by pet owners, has threatened native species with extinction. Objects controlled by AI, which we will likely increasingly share our environment with, such as autonomous taxis and food delivery robots, as well as a variety of objects that are used by the military, may be abandoned by their owners and continue to operate. Over time, these objects …

Associational Inference With Many Potential Covariates: Bayesian Information Criterion Elastic Net, Farideh Bagherzadeh Khiabani, I-Chan Huang, Jose Miguel Martinez Martinez, Shizue Izumi, Sedigheh Mirzaei, Tiange Zheng, Irina Dinu, Yutaka Yasui

COBRA Preprint Series

Background: An emerging feature in modern biomedical research is collecting and analyzing numerous variables. In the presence of many potential covariates, inference becomes challenging requiring both distinguishing a set of covariates truly associated with an outcome and estimating their corresponding regression coefficients consistently. Traditional statistical inference typically focuses on estimating coefficients assuming a pre-specified set of covariates. Further, advanced machine/statistical learning methods performing both selection and estimation predominantly focus on outcome prediction rather than association inference.

Methods: Motivated by our epidemiological research on long-term childhood cancer survivors, where we aimed to investigate associations between a large pool of longitudinal symptom …

The Role Of Autophagy In Intestinal Infection In Mice And C. Elegans, Gowri Kalugotla

Arts & Sciences Graduate Student Theses and Dissertations

Although autophagy, which is the process by which cells reallocate nutrients and eliminate unwanted materials, has been studied for decades, the connections between autophagy, inflammation, and viral immunity are still under investigation. Our studies focus on two genes: murine Epg5, which is involved in fusion of the autophagosome and lysosome, and C. elegans atg-3, which is important for the elongation of the phagophore. Here, we find that Epg5 mutation protects against enteric viruses including norovirus and rotavirus. We identify IFN- responsive genes as a key alteration and observe that Epg5 mutant mice exhibit substantial alterations in the intestinal microbiota. Surprisingly, …

Energetic Heterogeneity In Retinal Ganglion Cells: Role Of Neuronal Activity And Implications For Resilience, Zelun Wang

Arts & Sciences Graduate Student Theses and Dissertations

Retinal ganglion cells (RGCs) form the only connection between the eye and the brain via their axons in the optic nerve. In diseases such as glaucoma, RGCs undergo irreversible neurodegeneration leading to vision loss. RGCs consist of multiple types differing in morphology, gene expression, and signaling properties. Moreover, these types exhibit differential survival after axon injury. What cellular properties vary between RGC types that could underlie their heterogeneous response to neurodegeneration? Given that energy metabolism is tightly optimized for the homeostatic and active functions of different neurons, physiologically distinct RGC types likely exhibit divergent energetic characteristics. Furthermore, energy metabolism is …

Etv2 Mediated Differentiation Of Human Pluripotent Stem Cells Results In Functional Endothelial Cells For Engineering Advanced Vascularized Microphysiological Models, Shun Zhang, Zhengpeng Wan, Lei Wang, Caihong Wu, Junkai Zhang, Sarah Spitz, Xun Wang, Marie A. Floryan, Mark F. Coughlin, Francesca M. Pramotton, Liling Xu, Ron Weiss, Roger D. Kamm

Michigan Tech Publications

Patient-specific microphysiological models have become a valuable tool for broad applications, revolutionizing biomedical research. However, limitations persist, with functional vasculature being a significant challenge. With the discovery of ETV2's determinant role in specifying EC lineages during differentiation, researchers have adopted techniques involving ETV2 overexpression to produce h-iECs more efficiently and consistently. Here, we generated multiple h-iPSC lines with inducible ETV2 expression, and subsequently differentiated them into h-iECs, which were validated functionally and by key endothelial markers and RNA-seq analysis. These cells are capable of reproducibly self-organizing into stable microvascular networks (MVNs) in a microfluidic chip, forming lumenized and functional vessels …

Three Butterfly Genera Across The Central Texas Suture Zone, Qian Cong, Jing Zhang, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Genome-scale analyses of butterfly specimens across the Central Texas Suture Zone revealed that several taxa currently treated as subspecies exhibit genomic differentiation similar to that observed between species. Further investigation and genomic sequencing of additional specimens from across the ranges of these taxa support this conclusion and result in the following changes to nomenclature and taxonomy. Two new subspecies of Nymphalidae Rafinesque, 1815 are described: Asterocampa louisa monterra Grishin, ssp. n. (type locality in Mexico: Nuevo León) and Asterocampa clyton plana Grishin, ssp. n. (type locality in USA: Texas, Denton Co.). The following taxa are recognized as species, not subspecies: …

Biofilm Architecture Determines Proliferation Of Phages And Plasmids, James B. Winans

Dartmouth College Ph.D Dissertations

This thesis explores how biofilm architecture determines the spread and ecological consequences for the bacteria-dependent genetic elements phages and plasmids. Using Escherichia coli and Vibrio cholerae as model microbes, and the genetic elements T7 phages, λ phages, and conjugative plasmid pED208, we investigate how spatial structure influences phage infection dynamics, plasmid transfer, and interbacterial interactions within biofilms. We show that densely packed biofilms can protect sensitive bacteria from phage exposure and modulate competitive outcomes between obligately lytic and temperate phages. We find that entirely different outcomes can coöccur within microns of each other dependent on biofilm structure. We also demonstrate …

Transcription Factors Daf-16/Foxo And Hlh-30/Tfeb Form A Regulatory Axis To Control Tubular Lsysosomes Formation In C. Elegans, Cristian Ricaurte

LSU Doctoral Dissertations

The development of therapies that can be applied in human health care to promote longer and healthier lives is one of the main goals of aging research. However, many of the interventions currently available have serious adverse effects that limit their translational potential. Thus, new strategies are urgently needed to promote healthy aging in humans. Here, we reveal a functional interaction between the insulin signaling pathway and mTOR pathway that promotes healthy aging in C. elegans via lysosomal tubulation. Their respective transcription factors, DAF-16/FOXO and HLH-30/TFEB cooperate, to drive the formation of tubular lysosomes (TLs) under various contexts, which contributes …

No Effect In Plasma Corticosterone Levels After Observation Of Diseased Conspecifics, B. M. Hardy, M. Chang, S. Mccallum, S. Santangelo, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Organisms commonly respond to stressors in their environment by increasing the secretion of corticosterone (CORT). While increased CORT is acknowledged as a response to predation risk by organisms inhabiting a landscape of fear, new research raises the potential for changes in CORT as a response to the risk of infection by organisms in their environment. An increase in CORT of a healthy, uninfected individual in response to their perception of the risk of infection in their environment could change their susceptibility to infection, highlighting a significant role for CORT to alter host–pathogen dynamics. To investigate the effects of infection risk …

Physical Changes Of Biomacromolecules Upon Covalent Surface Immobilization, Bianca Mercado Velez, Vaishali Sharma, Seth Kriz, Erico Freitas, Paul Goetsch, Caryn Heldt

Michigan Tech Publications

Immobilization of large biomacromolecules is often required for analytical quantification and physicochemical characterization. However, immobilization can alter the structure and size of the particles being studied. Here, two exosomes (derived from HEK-293 and MDA-MB-231 cells) and three viral particles (Suid herpesvirus 1 (SuHV), xenotropic murine leukemia virus (XmuLV), and porcine parvovirus (PPV)) were immobilized to different covalent chemistries to understand how surface chemistry influences particle deformation during immobilization. The surface chemistries explored were: (i) NHS (N-hydroxysulfosuccinimide) and EDC (1-ethyl-3-(3-(dimethylamino)propyl) carbodiimide hydrochloride), and (ii) poly l-lysine (PLL) and glutaraldehyde (GA). Morphological changes in biomolecules following immobilization were quantified by …

Mist: A Hierarchical Bayesian Framework For Detecting Differential Dna Methylation Dynamics In Single-Cell Data, Daoyu Duan, Wenjing Ma, Wen Tang, Hao Wu, Liangliang Zhang, Hao Feng

Faculty, Staff and Student Publications

Recent advancements in single-cell DNA methylation (scDNAm) sequencing technologies have enabled the profiling of epigenetic landscapes at unprecedented resolution, offering insights into cellular heterogeneity, differentiation and evolution. Trajectory inference, which orders cells along pseudotime, allows researchers to track genomics changes across continuous cell states and identify key loci exhibiting differential methylation. However, no methods currently exist to model methylation changes along pseudotime in scDNAm data. Here, we present a hierarchical Bayesian framework for scDNAm data analysis. Our method, named mist (methylation inference for single-cell along trajectory), models stage-specific biological variations, identifies genomic features with significant methylation changes along pseudotime, and …

Periodontal Disease And Its Association With Porphyromonas Gingivalis: Current Understanding Of Microbial Dysbiosis, Immunopathology And Immune Evasion, Samantha Robins, Alex Strachan, Vehid Salih, Andrew Foey

Peninsula Dental School

Porphyromonas gingivalis is described as a keystone pathogen associated with periodontal disease (PD), which exhibits enhanced representation upon microbial dysbiosis in such a chronic inflammatory disease. This oral pathogen drives and contributes to a dysregulated immune response, resulting in stages of aggressive destructive immune activation and inflammation punctuated by immune suppression, which underlies the relapsing–remitting nature of this disease. The understanding of key mechanisms and balance between protective innate, adaptive immune responses and dysregulated responses, linked to changes in the oral mucosal microbial environment, will afford researchers the potential to manipulate oral mucosal environments for clinical benefit. This review focuses …
