Faculty, Staff and Students Publications

Most biological processes are dynamic, yet experimental methods predominantly rely on steady-state measurements to investigate their underlying mechanisms. RNA localization is a fundamental aspect of eukaryotic cell organization and is dynamically regulated by cells. While extensively studied in specialized cell types for a limited number of candidate RNAs, the general principles governing dynamic RNA localization at a transcriptome-wide scale remain largely unexplored. Existing transcriptome-wide studies provide only a static snapshot of RNAs residing in specific cellular locales, in part due to the limited availability of tools for probing cellular spatial organization at biologically relevant scales. Here, we leverage the high …

Developing Field And Spaceflight Microscopy, Nikki Johnston

Dissertations and Theses

Designing for spaceflight favors the reduction of unnecessary features and cost-cutting, whether thisbe computation, hardware, or procedure. Resources are spent toward fortification and mission success over convenience. Such design goals paired with the relatively smaller budgets of academia lead us to do as much as we can in-house and use open-source as much as we can without compromising mission success. We also believe that thoroughly testing technology in extreme environments on earth is necessary for the success of a flight instrument. We focus on microscopy for life detection. I have spent my time here learning methods of hand-building microscopes to …

Viability Assessment Of Bovine Embryos: A Public Dataset And Deep Learning Baselines, Erfan Khayyati

All Graduate Theses and Dissertations, Fall 2023 to Present

Improving the success rates of cattle breeding is essential for sustainable agriculture, global food security, and high-quality livestock production. Currently, determining whether a lab-grown bovine embryo is healthy enough for a successful pregnancy requires highly trained experts to manually evaluate days of continuous time-lapse video footage. This process is not only incredibly time-consuming but also highly subjective; human reviewers often suffer from visual fatigue when tracking subtle, microscopic cellular changes over a seven-day period, leading to significant disagreement among even top experts on an embryo’s true potential. Furthermore, assessing bovine embryos is notoriously difficult due to their dark, lipid-dense cellular …

Genetic Regulation Of Uterine Organogenesis, Diana A. Machado

Dissertations and Theses (Open Access)

In eutherian and marsupial mammals, the site of embryo implantation and gestation is the uterus. The precursor tissue of the uterus, oviducts, cervix, and upper vagina is the Müllerian duct epithelium and its adjacent mesenchyme. Morphological uterine variation between species is established during embryogenesis by species-specific differences in Müllerian duct fusion at the midline, growth, and differentiation. For example, laboratory mice have a bipartite uterus with two uterine horns and a single cervix, whereas humans have a simplex uterus with a single chamber and single cervix. In humans, variations in the fusion process can alter typical uterine morphology, correlating with …

Sultan Qaboos University Journal For Science

Graphene offers tremendous potential for applications in biomedical and pharmaceutical areas, ranging from molecular diagnostics, biosensors, and prosthetics to implants and drug delivery. However, realising the full potential of graphene is blocked by a limited understanding of the nature and detail of its noncovalent interactions with biological molecules in aqueous dispersion, where such applications can be used. Here, we studied the adsorption of amino acids and peptide on graphene in water utilising Nuclear Magnetic Resonance spectroscopy by observing 1H signals of individual biomolecules when exposed to graphene. The peptide-graphene interactions appeared to be driven by the binding affinity of individual …

Thermoclock:A Novel Automated Temperature Regulation Device That Can Model Circadian Entrainment And Disruption In 2d And 3d In Vitro Models, Kaiyin Kelly Zhang, Cathryn A. Cutia, Chanelle A. Moise, Bhavna Kalyanaraman, Kaitlyn Chhe, Jiexin Wang, Michelle E. Farkas, Ilia N. Karatsoreos, Mary Harrington, Meghan E. Huber, Cathal J. Kearney

Biological Sciences: Faculty Publications

Circadian rhythms are critical for maintaining homeostasis and regulating physiological functions, and consequentially impact disease progression; yet, they remain largely overlooked in in vitro models used in preclinical research. One major barrier to rigorously testing the role of circadian rhythms in these models is the lack of accessible tools that seamlessly integrate into standard culture setups and are capable of sustainably delivering time cues to cells and tissues in long term experiments. Here, we present the ThermoClock, a low-cost, Arduino-based automated temperature control system capable of delivering independent temperature programs to multiple cultures simultaneously. Using circadian reporter U2OS cell lines …

Biographex: Multi-Level Explainability In Graph Neural Networks For Trustworthy Biomedical Ai, Muhammad Talha Sajid, Ahmad Kamran Malik, Nafees Qamar, Hasnian Abudullah, Aleem Ahmad

Biological and Biomedical Sciences Department Faculty Journal Articles

In biomedical research and clinical practices, Graph Neural Networks (GNNs) are playing an increasingly important role and have been applied to the problems of disease pathway detection, gene–disease relation prediction, etc. They show great potential for biomedical predictions; however, there are interpretability issues when used on complex datasets like gene expression data. Current explainability methods such as GNNExplainer are designed to explain individual instances, not the whole network. The absence of transparency hinders trust and limits the clinical/biomedical implementation of GNNs. Additionally, more interpretable models like GNN-SubNet and XGDAG do not fulfill the expectation of a clear picture for the …

Bivariate Current Status Data With Competing Risks Using Frailty Models, Biswadeep Ghosh

Doctoral Theses

Bivariate current status data with competing risks arises in many application areas, for example, carcinogenicity studies, epidemiological studies, reliability studies, etc..As par of our knowledge, bivariate current status data with competing risks has not received much attention in literature. We initiate this research focusing on modeling and estimation of quantities of interest in absence of any covariate. We model bivariate current status data with competing risks through different frailty structures in order to describe different kinds of association. We consider multiplicative frailty effect on different cause-specific baseline hazard functions. One important part of our analysis is to investigate the identifiability …

From Introduction To Biomass Dominance: The Invasive Fish Striped Piggy (Pomadasys Stridens) Reshaping Demersal Assemblages In The Eastern Mediterranean, Mehmet Cengi̇z Deval

Turkish Journal of Zoology

Rapid increases in the abundance and biomass of nonindigenous species have the potential to profoundly reshape demersal fish assemblages in the Eastern Mediterranean Sea, yet quantitative evidence from long-term standardized surveys remains scarce. In the present study, temporal changes in biomass dynamics and community structure were assessed using fishery-independent trawl surveys conducted on the continental shelf of Antalya Bay (GSA 24) during two periods a decade apart (2009–2010 and 2020–2021), with particular focus on the Lessepsian striped piggy Pomadasys stridens. Based on the second survey, in which both daytime and nocturnal sampling were conducted, the biomass index (BI) differed significantly …

Taxing Ai In The Wake Of The Emergence Of Agentic Ai, Reuven S. Avi-Yonah, Herbert Snitz

Articles

This article addresses taxation measures to regulate AI agents (i.e., AI that is not fully under the control of humans, including both ANI and AGI). In each case, the focus is on what the agent’s capabilities would be, not on how it becomes capable of successfully performing its tasks (though the latter would likely be relevant to important philosophical questions, e.g., might robots achieve sentience or consciousness, and if so, would they have rights?). Regarding mirroring what we human beings can do, the hallmark of AGI is that it will not be task-specific (like ANI), but will possess broad capabilities, …

Root Chemistry Effects On Soil Organic Matter Fractions Persist In Topsoil And Subsoil Of A Well-Drained Alfisol, Brian Rinehart, Justin Allen, Joeri Kaal, Dave Mcnear, Hanna Poffenbarger

Plant and Soil Sciences Faculty Publications

Subsoils have been identified as a potential target for building soil C stocks, given the older age and slower cycling of organic matter at depth. Plant roots deliver C deep into the soil profile, but there is limited experimental evidence as to which root traits are most effective at increasing subsoil C. To that end, we conducted a 13C natural abundance study to trace C from roots of differing quality into organic matter fractions in a shallow and deep soil layer of an Alfisol in Lexington, KY. The roots of four species were packed into nylon-wrapped tubes with soil and …
