Bison Alter The Northern Yellowstone Ecosystem By Breaking Aspen Saplings, Luke E. Painter, Robert L. Beschta, William J. Ripple

Aspen Bibliography

The American bison (Bison bison) is a species that strongly interacts with its environment, yet the effects of this large herbivore on quaking aspen (Populus tremuloides) have received little study. We documented bison breaking the stems of aspen saplings (young aspen > 2 m tall and ≤ 5 cm in diameter at breast height) and examined the extent of this effect in northern Yellowstone National Park (YNP). Low densities of Rocky Mountain elk (Cervus canadensis) after about 2004 created conditions conducive for new aspen recruitment in YNP's northern ungulate winter range (northern range). We sampled …

A Patient Perspective On Applying Intermittent Fasting In Gynecologic Cancer, Ashley Redding, Sara Santarossa, Dana Murphy, Mary P. Udumula, Adnan R. Munkarah, Miriana Hijaz, Ramandeep Rattan

Obstetrics, Gynecology and Women's Health Services Articles

OBJECTIVE: Researchers sought patient feedback on a proposed randomized controlled trial (RCT) in which gynecological cancer patients would modify their diets with intermittent fasting to gain insight into patients' perspectives, receptivity, and potential obstacles. A convenience sample of 47 patients who met the inclusion criteria of the proposed RCT provided their feedback on the feasibility and protocols of the RCT using a multi-method approach consisting of focus groups (n = 8 patients) and surveys (n = 36 patients).

RESULTS: Patients were generally receptive to the concept of intermittent fasting, and many expressed an interest in attempting it themselves. Patients agreed …

Anth201: Cross-Cultural Perspectives (Fall 2023), James Tolleson

Open Educational Resources

Cultural anthropology emerged to study the differences among human beings (and between human and non-human beings). This course will cover the foundations of the discipline, including a critical perspective on anthropology’s ties to European colonialism and the rise of global capitalism. Students will come away with an understanding of how cultural anthropologists study culture, defined as “a set of beliefs, practices, and symbols that are learned and shared. Together, they form an all-encompassing, integrated whole that binds people together and shapes their worldview and lifeways” (Brown, McIlwraith & Tubelle de González 2020, 6). We will also pay close attention to …

Small-Vessel Disease In The Brain, Cynthia V Pagba, Amit K Gupta, Alemayehu A Gorfe

Faculty, Staff and Student Publications

Mutations in KRAS account for about 20% of human cancers. Despite the major progress in recent years toward the development of KRAS inhibitors, including the discovery of covalent inhibitors of the G12C KRAS variant for the treatment of non-small-cell lung cancer, much work remains to be done to discover broad-acting inhibitors to treat many other KRAS-driven cancers. In a previous report, we showed that a 308.4 Da small-molecule ligand [(2R)-2-(N'-(1H-indole-3-carbonyl)hydrazino)-2-phenyl-acetamide] binds to KRAS with low micro-molar affinity [Chem. Biol. Drug Des.2019; 94(2):1441-1456]. Binding of this ligand, which we call ACA22, to …

Around The Table Of Nianyefan: Transformation Of Lu Cuisine, Rituals, And Gender Roles In The Mid And South Of Shandong Since The 1980s, Ximai Shi

Student Theses and Dissertations

Nianyefan (the reunion dinner on Chinese New Year’s Eve) is an essential part of the celebration of Chinese New Year. This study focuses on the transformation of nianyefan in the middle and south of Shandong during the past four decades with the purpose of discovering and interpreting the interactions with the changing social, political, and economic dynamics since the 1980s. The study found that the reforms since the 1980s have diluted the authentic feel of nianyefan in the middle and south of Shandong, while the culture of nianyefan is not simply passive but actively responds to them. It begins with …

Topics In Absolute And Relative Treatment Effects In Medical Data Models And Applications With A Continuous Response, Sangit Regmi

Student Theses and Dissertations

Medical data models aim to evaluate the effectiveness of different treatments in a patient population, and to determine the relative and absolute treatment effects. The aim of this thesis is to evaluate the use of the traditional model when relative treatment effects exists and further develops a new model to account for both the absolute and relative treatment effects for a continuous response. The new model can be seen as a generalization of the traditional model by incorporating the relative treatment effect. It is shown in the simulation studies and real data set that the new model is able to …

In the accompanying Comment1, He et al. argue that the determinant role of microbial carbon use efficiency in global soil organic carbon (SOC) storage shown in Tao et al. (2023)2 was overestimated because carbon inputs were neglected in our data analysis while they suggest that our model-based analysis could be biased and model-dependent. Their argument is based on a different choice of independent variables in the data analysis and a sensitivity analysis of two process-based models other than that used in our study. We agree that both carbon inputs and outputs (as mediated by microbial processes) matter when predicting SOC …

Daily Early-Life Exposures To Diet Soda And Aspartame Are Associated With Autism In Males: A Case-Control Study, Sharon Parten Fowler, David Gimeno Ruiz De Porras, Michael D Swartz, Paula Stigler Granados, Lynne Parsons Heilbrun, Raymond F Palmer

Faculty, Staff and Student Publications

Since its introduction, aspartame-the leading sweetener in U.S. diet sodas (DS)-has been reported to cause neurological problems in some users. In prospective studies, the offspring of mothers who consumed diet sodas/beverages (DSB) daily during pregnancy experienced increased health problems. We hypothesized that gestational/early-life exposure to ≥1 DS/day (DSearly) or equivalent aspartame (ASPearly: ≥177 mg/day) increases autism risk. The case-control Autism Tooth Fairy Study obtained retrospective dietary recalls for DSB and aspartame consumption during pregnancy/breastfeeding from the mothers of 235 offspring with autism spectrum disorder (ASD: cases) and 121 neurotypically developing offspring (controls). The exposure odds ratios (ORs) for DSearly and …

Entry Receptor Ldlrad3 Is Required For Venezuelan Equine Encephalitis Virus Peripheral Infection And Neurotropism Leading To Pathogenesis In Mice, Natasha M Kafai, Hana Janova, Matthew D Cain, Yael Alippe, Stefanie Muraro, Alan Sariol, Michelle Elam-Noll, Robyn S Klein, Michael S Diamond

The Brown Foundation: Institute of Molecular Medicine

Venezuelan equine encephalitis virus (VEEV) is an encephalitic alphavirus responsible for epidemics of neurological disease across the Americas. Low-density lipoprotein receptor class A domain-containing 3 (LDLRAD3) is a recently reported entry receptor for VEEV. Here, using wild-type and Ldlrad3-deficient mice, we define a critical role for LDLRAD3 in controlling steps in VEEV infection, pathogenesis, and neurotropism. Our analysis shows that LDLRAD3 is required for efficient VEEV infection and pathogenesis prior to and after central nervous system invasion. Ldlrad3-deficient mice survive intranasal and intracranial VEEV inoculation and show reduced infection of neurons in different brain regions. As LDLRAD3 is a determinant …

An Evolutionarily Nascent Architecture Underlying The Formation And Emergence Of Biomolecular Condensates, Nima Jaberi-Lashkari, Byron Lee, Fardin Aryan, Eliezer Calo

Faculty, Staff and Student Publications

Biomolecular condensates are implicated in core cellular processes such as gene regulation and ribosome biogenesis. Although the architecture of biomolecular condensates is thought to rely on collective interactions between many components, it is unclear how the collective interactions required for their formation emerge during evolution. Here, we show that the structure and evolution of a recently emerged biomolecular condensate, the nucleolar fibrillar center (FC), is explained by a single self-assembling scaffold, TCOF1. TCOF1 is necessary to form the FC, and it structurally defines the FC through self-assembly mediated by homotypic interactions of serine/glutamate-rich low-complexity regions (LCRs). Finally, introduction of TCOF1 …

Bcl-2 Inhibition Combined With Pparα Activation Synergistically Targets Leukemic Stem Cell-Like Cells In Acute Myeloid Leukemia, Chendi Xie, Hui Zhou, Dongmei Qin, Huijian Zheng, Yuanfang Tang, Wenjuan Li, Jie Zhou, Long Liu, Xinxin Yu, Hongpeng Duan, Yong Zhou, Zhifeng Li, Zhihong Fang, Yiming Luo, Bing Z Carter, Bing Xu, Jie Zha

Faculty, Staff and Student Publications

Persistence of leukemic stem cells (LSCs) is one of the determining factors to acute myeloid leukemia (AML) treatment failure and responsible for the poor prognosis of the disease. Hence, novel therapeutic strategies that target LSCs are crucial for treatment success. We investigated if targeting Bcl-2 and peroxisome proliferator activated receptor α (PPARα), two distinct cell survival regulating mechanisms could eliminate LSCs. This study demonstrate that the Bcl-2 inhibitor venetoclax combined with the PPARα agonist chiglitazar resulted in synergistic killing of LSC-like cell lines and CD34+ primary AML cells while sparing their normal counterparts. Furthermore, the combination regimen significantly suppressed AML …

Calculating The Difference In Stiffness Of Living T Cells Through Micropipette Aspiration, Minju Lee

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cardiovascular disease (CVD) accounted for 17.9 million deaths in 2019, with fibrosis contributing to nearly a quarter of these fatalities [1,2]. Fibrosis, characterized by excessive connective tissue formation, has been strongly linked to T cells, essential components of the immune system. This study explores the mechanisms of T cell activation and the subsequent changes in biophysical properties like diameter, stiffness, and elasticity, aiming to develop therapeutic strategies for fibrosis-related diseases, including CVD. Utilizing the micropipette aspiration technique, we accurately assessed T cell stiffness and observed a change in bulk cell stiffness upon activation. The results demonstrated increased fluid-like behavior in …

Faculty Scholarship

Advances in thermoresponsive materials have significantly impacted many biomedical fields. The unique behavior of reversible phase transition close to the physiological temperatures makes these types of materials a great candidate for a wide variety of biomedical applications including bioimaging, biosensing, injectables, smart surfaces, adhesives, biomanufacturing, and tissue engineering. Thermoresponsive behavior, mainly lower critical solution temperature (LCST) can be easily tuned by shifting the balance between hydrophobicity and hydrophilicity (e.g., by using comonomers or changing end groups) and modifying the molecular weight and architecture of the polymer. Hence, synthetic and characterization tools are critical in tailoring and precisely determining these properties. …

Saturating Growth Rate Against Phosphorus Concentration Explained By Macromolecular Allocation, Gabrielle Armin, Jongsun Kim, Keisuke Inomura

School of Earth, Environmental, & Marine Sciences Faculty Publications

The saturating relationship between phytoplankton growth rate and environmental nutrient concentration has been widely observed, yet the mechanisms behind the relationship remain elusive. Here, we use a mechanistic model of phytoplankton and show that the saturating relationship between growth rate and phosphorous concentration can be interpreted by intracellular macromolecular allocation. At low nutrient levels, the diffusive nutrient transport linearly increases with the phosphorous concentration, while the internal phosphorous requirement increases with the growth rate, leading to a non-linear increase in the growth rate with phosphorous. This increased phosphorous requirement is due to the increased allocation to biosynthetic and photosynthetic molecules. …

Aberrant activation of the forkhead protein FOXA1 is observed in advanced hormone-related cancers. However, the key mediators of high FOXA1 signaling remain elusive. We demonstrate that ectopic high FOXA1 (H-FOXA1) expression promotes estrogen receptor-positive (ER+) breast cancer (BC) metastasis in a xenograft mouse model. Mechanistically, H-FOXA1 reprograms ER-chromatin binding to elicit a core gene signature (CGS) enriched in ER+ endocrine-resistant (EndoR) cells. We identify Secretome14, a CGS subset encoding ER-dependent cancer secretory proteins, as a strong predictor for poor outcomes of ER+ BC. It is elevated in ER+ metastases vs. primary tumors, irrespective of ESR1 mutations. Genomic ER binding near …

Aggregated Molecular Phenotype Scores: Enhancing Assessment And Visualization Of Mass Spectrometry Imaging Data For Tissue-Based Diagnostics, Jessie R Chappel, Mary E King, Jonathon Fleming, Livia S Eberlin, David M Reif, Erin S Baker

Faculty, Staff and Students Publications

Mass spectrometry imaging (MSI) has gained increasing popularity for tissue-based diagnostics due to its ability to identify and visualize molecular characteristics unique to different phenotypes within heterogeneous samples. Data from MSI experiments are often assessed and visualized using various supervised and unsupervised statistical approaches. However, these approaches tend to fall short in identifying and concisely visualizing subtle, phenotype-relevant molecular changes. To address these shortcomings, we developed aggregated molecular phenotype (AMP) scores. AMP scores are generated using an ensemble machine learning approach to first select features differentiating phenotypes, weight the features using logistic regression, and combine the weights and feature abundances. …

Real-Time Length Sensing Of Braided Pneumatic Actuator Using Ir Time-Of-Flight Sensor, Luon B. Chung

Dissertations and Theses

Braided Pneumatic Actuators (BPAs) are used widely in robotics as artificial muscles because of their similar characteristics to biological muscles. When a BPA is pressurized, it expands in the radial direction and contracts in the longitudinal direction. The contraction generates a pulling force that is dependent on the input pressure and BPA length. Biological muscle also behaves in the same way where a pulling force is generated on a contraction. To control BPAs on a robot, the real-time pressure and length measurements are necessary. In this dissertation, I present a new method to measure length of BPAs in real-time using …

An Update On The Healthy Soldier Effect In U.S. Veterans, Erin Sullivan-Baca, Rizwana Rehman, Zulfi Haneef

Faculty, Staff and Students Publications

Introduction: The healthy soldier effect (HSE) describes a phenomenon of enduring health and lower mortality among veterans due in part to initial screening procedures and health care access. Although early data were supportive of a broad HSE among former military members, more recent investigations have suggested a possible attenuation of the effect with older age. The present study aimed to provide an update of the HSE using an expansive Veterans Health Administration (VHA)-wide sample with a particular focus on age and sex effects.

Materials and methods: Mortality data for veterans within the VHA were obtained from the VHA Support Service …

Daam2 Phosphorylation By Ck2Α Negatively Regulates Wnt Activity During White Matter Development And Injury, Chih-Yen Wang, Zhongyuan Zuo, Juyeon Jo, Kyoung In Kim, Christine Madamba, Qi Ye, Sung Yun Jung, Hugo J Bellen, Hyun Kyoung Lee

Faculty, Staff and Students Publications

Wnt signaling plays a vital role in oligodendrocyte (OL) development and has been implicated as an adverse event for myelin repair after white matter injury. Emerging studies have shed light on multimodal roles of Wnt effectors in the OL lineage, but the underlying molecular mechanisms and modifiable targets in OL remyelination remain unclear. Using genetic mouse development and injury model systems, we delineate a unique stage-specific function of Daam2 in Wnt signaling and OL development via a S704/T705 phosphorylation mechanism and determine a different role of the kinase CK2α in the regulation of OL development and myelin regeneration.

Development of effective therapies against SARS-CoV-2 infections relies on mechanistic knowledge of virus-host interface. Abundant physical interactions between viral and host proteins have been identified, but few have been functionally characterized. Harnessing the power of fly genetics, we develop a comprehensive Drosophila COVID-19 resource (DCR) consisting of publicly available strains for conditional tissue-specific expression of all SARS-CoV-2 encoded proteins, UAS-human cDNA transgenic lines encoding established host-viral interacting factors, and GAL4 insertion lines disrupting fly homologs of SARS-CoV-2 human interacting proteins. We demonstrate the utility of the DCR to functionally assess SARS-CoV-2 genes and candidate human binding partners. We show that …
