Protocol For An Agent-Based Model Of Recombination In Bacteria Playing A Public Goods Game, Isaiah Paolo A. Lee, Omar T. Eldakar, J. Peter Gogarten, Cheryl P. Andam
Biology Faculty Articles
Agent-based models are composed of individual agents coded for traits, such as cooperation and cheating, that interact in a virtual world based on defined rules. Here, we describe the use of an agent-based model of homologous recombination in bacteria playing a public goods game. We describe steps for software installation, setting model parameters, running and testing models, and visualization and statistical analysis. This protocol is useful in analyses of horizontal gene transfer, bacterial sociobiology, and game theory.

Interpretable Mechanistic And Machine Learning Models For Pre-Dicting Cardiac Remodeling From Biochemical And Biomechanical Features, 2023 Clemson University
Interpretable Mechanistic And Machine Learning Models For Pre-Dicting Cardiac Remodeling From Biochemical And Biomechanical Features, Anamul Haque
All Dissertations
Biochemical and biomechanical signals drive cardiac remodeling, resulting in altered heart physiology and the precursor for several cardiac diseases, the leading cause of death for most racial groups in the USA. Reversing cardiac remodeling requires medication and device-assisted treatment such as Cardiac Resynchronization Therapy (CRT), but current interventions produce highly variable responses from patient to patient. Mechanistic modeling and Machine learning (ML) approaches have the functionality to aid diagnosis and therapy selection using various input features. Moreover, 'Interpretable' machine learning methods have helped make machine learning models fairer and more suited for clinical application. The overarching objective of this doctoral …
Determining The Effects Of Glycocalyx Modifications On The Electrophysical Properties Of Human Mesenchymal Stem Cells, 2023 California State University - San Bernardino
Determining The Effects Of Glycocalyx Modifications On The Electrophysical Properties Of Human Mesenchymal Stem Cells, Rominna E. Valentine Ico
Electronic Theses, Projects, and Dissertations
Human mesenchymal stem cells (hMSCs) have gained popularity in clinical trials due to their multipotent differentiation characteristics, ability to secrete bioactive molecules, migrate into diseased or damaged tissues, and their immunosuppressive properties. HMSC cultures are heterogeneous, containing stem cells, partially differentiated progenitor cells, and fully differentiated cells. One of the major challenges with hMSCs therapeutic potential is the inability to select specific cell subpopulations due to an insufficient number of biomarkers. Often the biomarkers used, like those for fluorescence-activated cell sorting, are not sufficient to define hMSCs because they overlap with other cell types. Consequently, there is a need to …

The Persistence Of Blue Ash In The Aftermath Of Emerald Ash Borer May Be Due To Adult Oviposition Preferences And Reduced Larval Performance, 2023 Wright State University - Main Campus
The Persistence Of Blue Ash In The Aftermath Of Emerald Ash Borer May Be Due To Adult Oviposition Preferences And Reduced Larval Performance, Don Cipollini, Emily Morton
Biological Sciences Faculty Publications
- We examined the health of mature blue ash, Fraxinus quadrangulata, in two forests in southwestern Ohio in relation to that of mature white ash, F. americana, and examined the potential importance of oviposition preferences and larval resistance in the persistence of blue ash.
- Both blue ash and white ash were largely unaffected by emerald ash borer in 2012. By 2018, nearly 90% of the blue ash trees observed in these forests had full or nearly full canopies, as opposed to less than 20% of the white ash encountered in our studies. In 2021, blue ash maintained a …

Modeling Nonsegmented Negative-Strand Rna Virus (Nnsv) Transcription With Ejective Polymerase Collisions And Biased Diffusion, 2023 Baylor College of Medicine
Modeling Nonsegmented Negative-Strand Rna Virus (Nnsv) Transcription With Ejective Polymerase Collisions And Biased Diffusion, Felipe-Andres Piedra
Research Symposium
Background: The textbook model of NNSV transcription predicts a gene expression gradient. However, multiple studies show non-gradient gene expression patterns or data inconsistent with a simple gradient. Regarding the latter, several studies show a dramatic decrease in gene expression over the last two genes of the respiratory syncytial virus (RSV) genome (a highly studied NNSV). The textbook model cannot explain these phenomena.
Methods: Computational models of RSV and vesicular stomatitis virus (VSV – another highly studied NNSV) transcription were written in the Python programming language using the Scientific Python Development Environment. The model code is freely available on GitHub: …
Homeostatic Synaptic Plasticity Of Miniature Excitatory Postsynaptic Currents In Mouse Cortical Cultures Requires Neuronal Rab3a, 2023 Wright State University - Main Campus
Homeostatic Synaptic Plasticity Of Miniature Excitatory Postsynaptic Currents In Mouse Cortical Cultures Requires Neuronal Rab3a, Andrew G. Koesters, Mark M. Rich, Kathrin L. Engisch
Biological Sciences Faculty Publications
Following prolonged activity blockade, amplitudes of miniature excitatory postsynaptic currents (mEPSCs) increase, a form of homeostatic plasticity termed “synaptic scaling.” We previously showed that a presynaptic protein, the small GTPase Rab3A, is required for full expression of the increase in miniature endplate current amplitudes following prolonged blockade of action potential activity at the mouse neuromuscular junction in vivo (Wang et al., 2011), but it is unknown whether this form of Rab3A-dependent homeostatic plasticity shares any characteristics with central synapses. We show here that synaptic scaling of mEPSCs is impaired in mouse cortical neuron cultures prepared from Rab3A-/- and Rab3A Earlybird …

Zea E-Books Collection
Emerging infectious disease (EID) represents an existential threat to humanity. EIDs are increasing in frequency and impact because of climate change and other human activities. We are losing the battle against EIDs because of improper assessment of the risk of EID. This stems from adherence to a failed paradigm of pathogen-host associations that suggests EIDs ought to be both unpredictable and rare. That, in turn, leads to policies suggesting that crisis response is the best we can do. Real-time and phylogenetic assessments show EIDs to be neither rare nor unpredictable—this is the parasite paradox that shows the failures of the …

Pathogen Emergence As Complex Biological Invasion: Lessons From Dynamical Systems Modeling, Sudam Surasinghe, Marisabel Rodriguez, Victor Meszaros, Jane Molofsky, Salvador Almagro-Moreno, Brandon Ogbunugafor
Northeast Journal of Complex Systems (NEJCS)
Infectious disease emergence has become the target of cross-disciplinary efforts
that aim to understand and predict the shape of outbreaks. The many challenges
involved with the prediction of disease emergence events is a characteristic that in-
fectious diseases share with biological invasions in many subfields of ecology (e.g.,
how certain plants are able to successfully invade a new niche). Like infectious
diseases, biological invasions by plants and animals involve interactions between
agents (pathogens and plants in their respective cases) and a recipient niche. In
this study, we examine the problem of pathogen emergence through the lens of a
framework first …
Regulation Of The Wnt/Wingless Receptor Lrp6/Arrow By The Deubiquitylating Complex Usp46, 2023 Dartmouth College
Regulation Of The Wnt/Wingless Receptor Lrp6/Arrow By The Deubiquitylating Complex Usp46, Zachary T. Spencer
Dartmouth College Ph.D Dissertations
The evolutionarily conserved Wnt/Wingless signal transduction pathway is critical for the proper development of all animals and implicated in numerous diseases in adulthood. Upon binding of the Wnt/Wingless ligand, a cascade of events culminates in inactivation of the destruction complex, a negative regulator of the pathway, and the subsequent formation of singalosomes which mediate pathway activation. A critical component of signalosome formation is the Wnt/Wingless receptor LRP6/Arrow. Upon canonical pathway activation, LRP6/Arrow undergoes activation via phosphorylation by several kinases and complexes with another Wnt/Wingless receptor Frizzled, along with several cytoplasmic components. While many studies have investigated the regulatory mechanisms of …
Gabaergic Synaptic Scaling Is Triggered By Changes In Spiking Activity Rather Than Transmitter Receptor Activation, 2023 Wright State University - Main Campus
Gabaergic Synaptic Scaling Is Triggered By Changes In Spiking Activity Rather Than Transmitter Receptor Activation, Carlos Gonzalez-Islas, Zahraa Sabra, Ming-Fai Fong, Pernille Bülow, Nicholas Au Yong, Kathrin Engisch, Peter Wenner
Biological Sciences Faculty Publications
Homeostatic plasticity represents a set of mechanisms that are thought to recover some aspect of neural function. One such mechanism called AMPAergic scaling was thought to be a likely candidate to homeostatically control spiking activity. However, recent findings have forced us to reconsider this idea as several studies suggest AMPAergic scaling is not directly triggered by changes in spiking. Moreover, studies examining homeostatic perturbations in vivo have suggested that GABAergic synapses may be more critical in terms of spiking homeostasis. Here we show results that GABAergic scaling can act to homeostatically control spiking levels. We find that increased or decreased …

The traditional funeral service industry has enormous environmental and financial costs. In contrast, green burial, and Natural Organic Reduction (NOR), accelerate the human body’s degradation and reduce toxic substances in the land, assuming responsibility for our burden on the earth. They provide a gateway between us and the processes of nature and ask us to set aside self-consciousness to accept our oneness with the universe. By gifting our bodies back to the earth, where decomposition enriches soils and nurtures the growth of other life forms, we honor those who have transitioned to another state by continuing the cycle of renewal. …

Novel Natural Compounds Derived From Tcm In The Treatment Of Food Induced Anaphylaxis, Ibrahim Musa
NYMC Student Theses and Dissertations
Food allergy is a highly prevalent disease affecting about 30 million people in the U.S. It is managed primarily by food avoidance due to lack of promising treatment options. ASHMI (anti-asthma herbal intervention) which consists of three components, Sophorae flavescentis, Ganoderma lucidum, Glycyrrhiza uralensis has been shown to inhibit allergic lung inflammation in antigen sensitized and challenged mice. In this study we isolate and identify the active compound in Sophorae flavescentis, characterized the mechanism of IgE inhibitory effect, biomarkers and potential to prevent food anaphylaxis.
To separate and identify the compounds we used column chromatography, high-performance liquid chromatography, mass …

Pasturelands As Natural Climate Solutions: A Socioecological Study Of Tree Carbon And Beef Production Trade-Offs, 2023 James Madison University
Pasturelands As Natural Climate Solutions: A Socioecological Study Of Tree Carbon And Beef Production Trade-Offs, Bela Starinchak
Masters Theses, 2020-current
Forest restoration is the most effective natural climate solution, with the potential to sequester 37% of the carbon dioxide (CO2) needed to reach the Paris climate mitigation goal. Cattle pastures offer an underutilized opportunity to increase global forest restoration efforts, improve biodiversity, and maximize carbon storage through the adoption of management strategies that prioritize the incorporation of trees into pasturelands. However, remote estimations of tree carbon storage in pastoral systems have never been field-verified and their accuracy is unclear. Furthermore, the effect of increased trees on cattle production is understudied across biomes. Lastly, the restoration potential of these …
