The Mutation Of The Model Man: 1936-1945, Andrea Rassmussen
The Mutation Of The Model Man: 1936-1945, Andrea Rassmussen
The Thetean: A Student Journal for Scholarly Historical Writing
Masculinity, or the ideal male model, differed significantly in the war years from the late 1930s. This evolution can be seen through articles in Coronet, in which the majority of stories had male heroes whose physical characteristics, personalities, and social graces all changed as the war started and progressed. The ideal man shifted from the Successful Businessman of the 30s to the Individualistic Team Player of the 40s. I chose these names because they encapsulate the contradiction that made up the model man of the war years. No more was the ideal a cutthroat businessman concerned with nothing except succeeding, …

“It’S God’S Country”: The University Of Montana, Flathead Indian Reservation, And Dispossession, Dylan Tate Yonce
UM Graduate Student Research Conference (GradCon)
In the early decades of the twentieth century, the University of Montana (UM) developed from a small frontier college into an influential research institution. During its maturation process, the University relied on the acquisition of land to expand. In addition to its main campus in Missoula, the university sought out land for research and recreation. When Congress passed the Flathead Allotment Act (1904), the University became one of many non-Native beneficiaries of federal land dispossession policy in the United States in the 20th century. Existing scholarship has largely honed in on “land grant” universities established through the Morrill Act (1862) …

It Ain’T Necessarily So: Ludwig Boltzmann’S Darwinian Notion Of Entropy, Steven Gimbel
It Ain’T Necessarily So: Ludwig Boltzmann’S Darwinian Notion Of Entropy, Steven Gimbel
Philosophy Faculty Publications
Ludwig Boltzmann's move in his seminal paper of 1877, introducing a statistical understanding of entropy, was a watershed moment in the history of physics. The work not only introduced quantization and provided a new understanding of entropy, it challenged the understanding of what a law of nature could be. Traditionally, nomological necessity, that is, specifying the way in which a system must develop, was considered an essential element of proposed physical laws. Yet, here was a new understanding of the Second Law of Thermodynamics that no longer possessed this property. While it was a new direction in physics, in other …

Now It’S Your Turn!: Eye Blink Rate In A Jenga Task Modulated By Interaction Of Task Wait Times, Effortful Control, And Internalizing Behaviors, Kelley E. Gunther, Xiaoxue Fu Ph.D., Leigha A. Macneill, Morgan Jones, Briana Ermanni, Koraly Pérez-Edgar
Now It’S Your Turn!: Eye Blink Rate In A Jenga Task Modulated By Interaction Of Task Wait Times, Effortful Control, And Internalizing Behaviors, Kelley E. Gunther, Xiaoxue Fu Ph.D., Leigha A. Macneill, Morgan Jones, Briana Ermanni, Koraly Pérez-Edgar
Faculty Publications
Dopamine is a versatile neurotransmitter with implications in many domains, including anxiety and effortful control. Where high levels of effortful control are often regarded as adaptive, other work suggests that high levels of effortful control may be a risk factor for anxiety. Dopamine signaling may be key in understanding these relations. Eye blink rate is a non-invasive proxy metric of midbrain dopamine activity. However, much work with eye blink rate has been constrained to screen-based tasks which lack in ecological validity. We tested whether changes in eye blink rate during a naturalistic effortful control task differ as a function of …

Highly Efficient Dopamine Sensing With A Carbon Nanotube-Encapsulated Metal Chalcogenide Nanostructure, Harish Singh, Jiandong Wu, Kurt A.L. Lagemann, Manashi Nath
Chemical and Biochemical Engineering Faculty Research & Creative Works
Carbon nanotube-encapsulated nickel selenide composite nanostructures were used as nonenzymatic electrochemical sensors for dopamine detection. These composite nanostructures were synthesized through a simple, one-step, and environmentally friendly chemical vapor deposition method, wherein the CNTs were formed in situ from pyrolysis of a carbon-rich metallo-organic precursor. The composition and morphology of these hybrid NiSe2-filled carbon nanostructures were confirmed by powder X-ray diffraction, Raman, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy images. Electrochemical tests demonstrated that the as-synthesized hybrid nanostructures exhibited outstanding electrocatalytic performance toward dopamine oxidation, with a high sensitivity of 19.62 μA μM-1 cm-2, low detection limit, broad linear …

Diagnostic Potential Of Exosomal Extracellular Vesicles In Oncology, Marco Ruiz
All Publications
Liquid biopsy can detect circulating cancer cells or tumor cell-derived DNA at various stages of cancer. The fluid from these biopsies contains extracellular vesicles (EVs), such as apoptotic bodies, microvesicles, exomeres, and exosomes. Exosomes contain proteins and nucleic acids (DNA/RNA) that can modify the microenvironment and promote cancer progression, playing significant roles in cancer pathology. Clinically, the proteins and nucleic acids within the exosomes from liquid biopsies can be biomarkers for the detection and prognosis of cancer. We review EVs protein and miRNA biomarkers identified for select cancers, specifically melanoma, glioma, breast, pancreatic, hepatic, cervical, prostate colon, and some hematological …

Feature Engineering And Supervised Machine Learning To Forecast Biogas Production During Municipal Anaerobic Co-Digestion, Hunter W. Schroer, Craig L. Just
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Municipalities with excess anaerobic digestion capacity accept offsite wastes for co-digestion to meet sustainability goals and create more biogas. Despite the benefits inherent to co-digestion, the temporal and compositional heterogeneity of external waste streams creates operational challenges that lead to upsets or conservative co-digestion. Given the complex microbial bioprocesses occurring during anaerobic digestion, prediction and modeling of the outcomes can be challenging, and machine learning has the potential to improve understanding and control of co-digestion processes. Biogas flows are a surrogate for process health, and here, we predicted biogas production from historical data collected by a water resource recovery facility …

School of Veterinary and Biomedical Sciences: Faculty Publications
Introduction: Control of Campylobacter from farm to fork is challenging due to the frequent emergence of antimicrobial-resistant isolates. Furthermore, poultry production systems are known reservoirs of Campylobacter. The twinarginine translocation (Tat) pathway is a crucial bacterial secretion system that allows Campylobacter to colonize the host intestinal tract by using formate as the main source of energy. However, Tat pathway is also a major contributing factor for resistance to copper sulfate (CuSO4).
Methods: Since mammals and chickens do not have proteins or receptors that are homologous to bacterial Tat proteins, identification of small molecule (SM) inhibitors …

Tractor Beams And Disease: Probing Repeat Rna Structure Through Single Molecule Force Spectroscopy, Joshua Webster-Ford
Tractor Beams And Disease: Probing Repeat Rna Structure Through Single Molecule Force Spectroscopy, Joshua Webster-Ford
Undergraduate Honors Theses
Huntington’s Disease is characterized by an extended (CAG)n repeat found in the huntingtin (Htt) gene. While the typical human contains 6-20 CAG repeats, people with over 36 repeats manifest symptoms of the disease. The extended CAG repeats allow the Htt pre-mRNA transcript to form a hairpin loop structure which can sequester certain vital proteins such as Muscleblind like protein 1 (MBNL1), hindering their functional role. Further understanding the structure of the MBNL1-RNA complex is possible through force spectroscopy, or “optical tweezers”, applied on the single molecule level. Force spectroscopy generates force versus distance plots for individual RNA molecules, revealing the …

Growth factor receptor-bound protein 2 (GRB2) is a cytoplasmic adapter for tyrosine kinase signaling and a nuclear adapter for homology-directed-DNA repair. Here we find nuclear GRB2 protects DNA at stalled replication forks from MRE11-mediated degradation in the BRCA2 replication fork protection axis. Mechanistically, GRB2 binds and inhibits RAD51 ATPase activity to stabilize RAD51 on stalled replication forks. In GRB2-depleted cells, PARP inhibitor (PARPi) treatment releases DNA fragments from stalled forks into the cytoplasm that activate the cGAS-STING pathway to trigger pro-inflammatory cytokine production. Moreover in a syngeneic mouse metastatic ovarian cancer model, GRB2 depletion in the context of PARPi treatment …
Development Of Quantitative Structure Activity Relationships (Qsars) For Predicting The Aggregation Of Tio2 Nanoparticles Under Favorable Conditions, Jaewoong Lee
Department of Civil and Environmental Engineering: Faculty Publications
This study developed multi-linear regression (MLR) quantitative structure-activity relationships (QSARs) to predict n-TiO2 aggregation in the presence of high concentrations of representative emerging organic contaminants (EOCs), which presented favorable conditions to interaction with n-TiO2. The largest diameter change (Δ 517 nm at 0 h and Δ 1164 nm at 12 h) of n-TiO2 was observed by estrone, while the smallest diameter change (Δ -114 nm at 0 h and – 4 nm at 12 h) was observed by lincomycin during experimental periods. In addition, the zeta potential changes of n-TiO2 were …

Department of Medicine Faculty Papers
The advancement of RNAseq and isoform-specific expression platforms has led to the understanding that isoform changes can alter molecular signaling to promote tumorigenesis. An active area in cancer research is uncovering the roles of ubiquitination on spliceosome assembly contributing to transcript diversity and expression of alternative isoforms. However, the effects of isoform changes on functionality of ubiquitination machineries (E1, E2, E3, E4, and deubiquitinating (DUB) enzymes) influencing onco- and tumor suppressor protein stabilities is currently understudied. Characterizing these changes could be instrumental in improving cancer outcomes via the identification of novel biomarkers and targetable signaling pathways. In this review, we …
Traveling Wave Fronts Of Reaction Diffusion Differential Equations With Diffusive Delay In Biological And Chemical Models, William Barker
Traveling Wave Fronts Of Reaction Diffusion Differential Equations With Diffusive Delay In Biological And Chemical Models, William Barker
Theses and Dissertations
Functional differential equations (FDE) incorporate past states and or rates in the modeling of physical phenomena. Unlike ordinary and even some partial differential equations there is no method to find solutions of general FDE explicitly. Therefore, in order to study solutions of FDE, iterative techniques are often employed. Reaction diffusion equations are a specific type of partial differential equations that model diffusive spread, the rate of spread of due to a reaction term of some quantity. These equations arise naturally in fields such as biology, ecology and chemistry. In terms of studying dynamics of populations, previous states and even rates …

RATIONALE: Polycystic ovary syndrome (PCOS) is the most common reproductive endocrine disorder among women of childbearing age and is the primary cause of anovulatory infertility, accounting for 70% to 80% of cases. Ovulation induction is the main treatment approach for infertile patients with PCOS. Commonly utilized medications for this purpose are clomiphene citrate (CC) and letrozole (LE). Clomiphene citrate administration results in an ovulation rate ranging from 60% to 85%, while the pregnancy rate is limited to 35% to 40%, and a further reduction is observed in live birth rates. Letrozole demonstrates a slightly higher pregnancy rate and live birth …

Programmed cell death-1 (PD-1) is a potent immune checkpoint receptor on T lymphocytes. Upon engagement by its ligands, PD-L1 or PD-L2, PD-1 inhibits T cell activation and can promote immune tolerance. Antagonism of PD-1 signaling has proven effective in cancer immunotherapy, and conversely, agonists of the receptor may have a role in treating autoimmune disease. Some immune receptors function as dimers, but PD-1 has been considered monomeric. Here, we show that PD-1 and its ligands form dimers as a consequence of transmembrane domain interactions and that propensity for dimerization correlates with the ability of PD-1 to inhibit immune responses, antitumor …
Agential Cuts For Justice: Honoring Complexity In Research Through Intersectional Design Dimensions, Nadia Behizadeh
Agential Cuts For Justice: Honoring Complexity In Research Through Intersectional Design Dimensions, Nadia Behizadeh
The Qualitative Report
This article explores the complexity and challenges of making decisions regarding which theories and social categories (e.g. race, class) should be emphasized in justice-centered research that includes participants’ identities as key variables in the design. Drawing on theories of intersectionality, agential realism, and complexity, the author proposes four intersectional design dimensions to help justice-centered researchers honor complexity: reflection on self and purpose; making agential cuts; complexifying social categories; and intersectional and collaborative re-view. Each dimension is illustrated with theory and empirical examples, mostly drawing from the field of educational research. By attending to and continually revisiting agential cuts related to …

Crop production is being impacted by higher temperatures, which can decrease food yield and pose a threat to human nutrition. In the current study, edible and wild radish sprouts were exposed to elevated growth temperatures along with the exogenous application of various elicitors to activate defense mechanisms. Developmental traits, oxidative damage, glucosinolate and anthocyanin content, and antioxidant capacity were evaluated alongside the development of a predictive model. A combination of four elicitors (citric acid, methyl jasmonate—MeJa, chitosan, and K2SO4) and high temperatures were applied. The accumulation of bioactives was significantly enhanced through the application of two elicitors, K2SO4 and methyl …

IL-33 is a cytokine central to type 2 immune pathology in chronic airway disease. This cytokine is abundantly expressed in the respiratory epithelium and increased in disease, but how expression is regulated is undefined. Here we show that increased IL33 expression occurs from multiple noncanonical promoters in human chronic obstructive pulmonary disease (COPD), and it facilitates production of alternatively spliced isoforms in airway cells. We found that phorbol 12-myristate 13-acetate (PMA) can activate IL33 promoters through protein kinase C in primary airway cells and lines. Transcription factor (TF) binding arrays combined with RNA interference identified activator protein (AP) TFs as …

Understanding and managing the response of marine ecosystems to human pressures including climate change requires reliable large-scale and multi-decadal information on the state of key populations. These populations include the pelagic animals that support ecosystem services including carbon export and fisheries. The use of research vessels to collect information using scientific nets and acoustics is being replaced with technologies such as autonomous moorings, gliders, and meta-genetics. Paradoxically, these newer methods sample pelagic populations at ever-smaller spatial scales, and ecological change might go undetected in the time needed to build up large-scale, long time series. These global-scale issues are epitomised by …

Calcium oxalate (CaOx) is the most common type of urinary stone, and its formation is driven by decreased urine volume, increased lithogenic substances, and decreased stone inhibitory compounds (specifically citrate). Low urinary citrate excretion (hypocitraturia) is a prominent risk factor in Thai urolithiasis patients.
Objective: To measure the urinary EC, urinary calcium, and urine specific gravity in CaOx stone patients compared with non-stone forming (NSF) subjects.
Method: The urinary EC was measured in 24-h urine samples obtained from 42 CaOx stone patients and 121 NSF subjects. Urinary calcium …
