Investigating Naïve Stem Cell Maintenance With Fbf Mutants In C. Elegans Germline, Deanna E. Cuello

University of Montana Conference on Undergraduate Research (UMCUR)

Stem cells are essential to establish tissue via proliferation and differentiation. We study stem cells of Caenorhabditis elegans germline as a model for development and differentiation. The distal tip cell (DTC) houses the stem cell niche which contains ~200 mitotically dividing cells. As germline stem cells move proximally the cells begin to differentiate while entering meiotic division (Austin and Kimble, 1987). Amongst the stem cells, previous research distinguished two populations, those that are naïve stem cells and others that are committed to differentiation (Cinquin, et. al, 2010).

We study stem cell regulation by two RNA-binding proteins, FBF-1 and FBF-2 that …

Ph Regulator Ae2 Is Important For Brain Development, Celia Elizabeth Keil

University of Montana Conference on Undergraduate Research (UMCUR)

Drosophila melanogaster (fruit fly) is a model organism that undergoes many of the same processes for brain development that humans do. Work from our lab finds that pH regulation is important for brain development. The pH regulator, Ae2, is present at the cell membrane where it expels bicarbonate ions in exchange for chloride. Importantly, humans also express ae2 (SLCA4). It is not a well-studied protein, but low levels of SLCA4 are hypothesized to be associated with primary biliary cirrhosis. In other organ systems, the Ae2 exchanger was found to be important for development. Thus, we aimed to determine if …

Understanding Dosage In Speech Sound Disorder Therapy, Pyper Trumble, Megan Andersen

University of Montana Conference on Undergraduate Research (UMCUR)

Speech-language pathologists provide speech and language therapy to people who have difficulty communicating their wants, needs, or ideas. Within therapy there are many unknown variables that determine its effectiveness, especially when working with preschool children who have difficulties saying speech sounds. To develop a better understanding of these unknown variables, the current research explored dosage. Dosage is the number of prompts that a clinician gives to a child to say a target sound within one treatment session (Farquharson et al, 2022). Dosage is an under studied element within therapy with potentially large effects on the amount and rate of progress …

Women Of Missoula: Menstruation And Refugees, Bella Spencer, Samantha Boutte, Emmily Valencia, Brooklyn Grubbs, Holly Sudol

University of Montana Conference on Undergraduate Research (UMCUR)

Abstract

Stigmatization, lack of accessible menstrual products, and an overall misconstrued sense of menstruation impact menstruators at a disproportionate rate. When diving into the literature, we found that refugee women not only faced stigmas and a lack of access to menstrual products and education, but also ran into cultural barriers and differing attitudes on menstruation. To address this issue, we formulated the idea of a menstrual drive. Instead of focusing on refugee menstruators as a whole, our focus will be the refugee population in Missoula, MT. We recognize that the stigmatization of menstruation is an ongoing global issue that affects …

The Proud Boys Raging Righteously At The U.S. Capitol On January 6th, 2021: A Hate Group In Action, Daniel Rothbart

International Conference on Hate Studies

Righteous rage constitutes an expression of political power for many hate groups operating currently in the United States, enticing them toward emotionally charged aggression against their adversaries. We offer a case study of one such group—the Proud Boys—in the context of their violent attack of the U.S. Capitol on January 6, 2021. Rather than a momentary feeling, their righteous rage is a potent force for forming, defining, and organizing their mission to overpower their adversaries. In particular, their righteous rage is defined by (a) behavioral manifestations, (b) the emotional contagious impact of such manifestations, and (c) the centrality of raging …

Re-Imagining Teacher Education As An Andragogy Of Hope, Ivon Prefontaine

International Conference on Hate Studies

Building on a co-authored book chapter, A Futures Perspective for an Andragogy of Hope, I propose to explore the role teachers can play in opening up hopeful pedagogical spaces for K-12 students. In the chapter, we describe a pedagogic/andragogic creed that includes “I am a teacher full of the spirit of hope, in spite of all that stands to the contrary. I am a teacher who refuses the disillusionment that consumes and immobilizes” (Freire, 2014, p. 94). This echoes my opening words which included the following from the Prayer of St. Francis: “where there is despair [let me sow] hope.” …

Ethno-Political Tribalism As A Cause Factor Of Inequality And Hate (Case Of The Central Asian Countries), Temirkhan Mukhambetov

International Conference on Hate Studies

The causes of conflicts that occur in different countries of the world are often indicated by the human instinct of tribalism. The article is devoted to the study, analysis and search for ways to solve the problems of ethnopolitical tribalism.

The main features of a tribal society are tribal strife, hostility towards other sub-ethnic groups. The ethno-political tribalism that often forms in such a society is one of the most dangerous phenomena, since the representatives of the dominant tribe who have seized power use the power of power to suppress competing tribes. As a result, instead of forming a national …

Vigilantism And Hate Motivated Mob Lynching Cases In India, Sumant Kumar

International Conference on Hate Studies

Vigilantism is not a new concept; it is a reflection of the platitude and failure of the state in which state always blames their own people for taking law into their hands, and by citizens, who justify their measures on state inactiveness. Vigilantism defines as “the act of taking the law into one’s own hands and attempting to enact justice according to one’s own understanding of right and wrong”. Incidents of mob lynching are encouraged within the atmosphere of hate, rumors and distrust created through continued propaganda. There are several incidents on murder, attempt to murder, harassment, assault, gang-rape etc. …

The Role Of Serca In Neural Development And Brain Tumors, Hannah Madison Christman

University of Montana Conference on Undergraduate Research (UMCUR)

Ion channels are essential for neural function, playing a variety of necessary cellular roles including excitability, maintaining ion gradients, and volume control. While the role of ion channels in neurons is well-defined, much less is known about excitability in neural progenitor cells. Recently it has emerged that these neural precursors may be affected by channelopathies, indicating a critical role of ion channels in neural development. Using the model system Drosophila melanogaster (fruit fly), I investigated the role of the ion channel SERCA (sarco/endoplasmic reticulum Ca²⁺ATPase). SERCA is a vital calcium ion pump located on the wall of the …

Effects Of Cultural Matching And Identity Safety: An Examination Of Indigenous Student’S School Experiences, Tori Horton, Susie Michalek, Caitlin Carvalho

University of Montana Conference on Undergraduate Research (UMCUR)

Cultural matching refers to the reflection of one’s own culture in day-to-day life, which is critical for nurturing one’s sense of acceptance and identity in the world (Rip et.al., 2020). Identity safety is when one’s social identity is welcomed and valued rather than viewed as a barrier to success The presence of cultural matching and identity safety is important in educational settings throughout childhood and adolescence, as both are crucial to students’ overall well-being and identity. Opportunities to express one’s culture in the classroom is essential for a sense of belonging and safety (Steele & Cohen-Vargas, 2013); however, Indigenous students …

Low-Dose Psilocybin Enhances Novel Object Recognition But Not Inhibitory Avoidance In Adult Rats, Claire E. Miller, Colin R. Del Valle, Margaret M. Naylor, Heather R. Sparkman, Connor M. Cruea, Rachel E. Rice, Brooke E. Bramlage, Lillianna P. Puppel, Madison L. Brown, Aleece K. Al-Olimat, Elizabeth S. Dietz, Phillip R. Zoladz

ONU Student Research Colloquium

Given the recently renewed interest in using psychedelics to aid in the treatment of psychological disorders, we aimed to examine the impact of psilocybin, a 5-HT_2A agonist, on learning and memory in rodents. Previous work has demonstrated that psilocybin and other 5-HT_2A agonists can enhance fear conditioning, fear extinction, and novel object recognition (NOR). Thus, we predicted that low doses of psilocybin would enhance inhibitory avoidance (IA) and NOR memory. In the first experiment, adult male and female Sprague-Dawley rats underwent step-through IA training (involving 0.45, 0.65, or 1 mA scrambled footshock) and were injected intraperitoneally (i.p.) with …

Parker, Kristen E. Long, Mercedes L. Stanek, Matthew S. Risner, John G. Blasco, Koen N. Suzelis, Kelsey M. Siereveld, Shannon B. Carnes, Boyd R. Rorabaugh, Phillip R. Zoladz

ONU Student Research Colloquium

Most research examining the impact of stress on learning and memory has exposed participants to a stressor and measured how it affects learning and memory for unrelated material (e.g., list of words). Such work has been helpful, but it has not been the most translational to the human condition. When considering phenomena such as intrusive memories in post-traumatic stress disorder (PTSD) or an eyewitness's memory for a crime, it is most useful to know what an individual remembers about the stress experience itself, not unrelated information. In prior work, investigators used a modified version of the Trier Social Stress Test …

Impact Of Acute Stress, Sex, And Childhood Maltreatment On Fear Learning And Fear Generalization In A Fear-Potentiated Startle Paradigm, Kayla M. Boaz, Chloe N. Cordes, Cassidy L. Pfister, Taylor D. Niese, Sydney L. Parker, Kristen E. Long, Mercedes L. Stanek, Boyd R. Rorabaugh, Seth D. Norrholm, Phillip R. Zoladz

ONU Student Research Colloquium

Many researchers approach the etiology of trauma-, stressor-, and anxiety-related mental disorders from the perspective of classical conditioning processes gone awry. According to this view, abnormal associative relationships between conditioned and unconditioned stimuli may underlie pathological anxiety and result in unusually intense fear memories or fear memories that cannot be properly extinguished. Recent work has expanded on this view by showing that many psychological disorders involving pathological anxiety are associated with an exaggerated form of stimulus generalization, leading individuals with such disorders to respond with fear and anxiety to a variety of contexts and cues that should not be threatening. …

Psilocybin Prevents Symptoms Of Hyperarousal And Enhances Novel Object Recognition In Rats Exposed To The Single Prolonged Stress Paradigm, Colin R. Del Valle, Heather R. Sparkman, Margaret M. Naylor, Connor M. Cruea, Rachel E. Rice, Claire E. Miller, Brooke E. Bramlage, Lillianna P. Puppel, Madison L. Brown, Aleece K. Al-Olimat, Elizabeth S. Dietz, Phillip R. Zoladz

ONU Student Research Colloquium

Pharmacotherapy for stress-related psychological disorders remains inadequate. Patients who are treated with conventional pharmacological agents frequently report negligeable symptom reduction, and, in most cases, less than 50% experience full remission. Clearly, there is a need for additional pharmaceutical research into both established and novel approaches to alleviate these conditions. Over the past several years, there has been a renewed interest in the use of psychedelics to aid in the treatment of psychological disorders. Several studies have reported promising results in patients with major depression, anxiety disorders, and post-traumatic stress disorder (PTSD) following treatment with psychedelic agents such as lysergic acid …
