3d Bioactive Thiol-Norbornene Hydrogels For Guiding Stem Cell Mechanosensing And Differentiation, Arielle Gsell

U-RISE Undergraduate Theses

Hydrogels are soft, highly hydrated polymeric networks commonly used as biomaterial scaffolds in tissue engineering. To mimic the extracellular matrix of tissues, hydrogels can be chemically modified to incorporate either bioactive molecules such as peptides, or physically modified with crosslinkers to alter hydrogel stiffness and degradation. Hydrogels with defined characteristics can be synthesized using chemical reaction schemes such as photo-click chemistry, which offers spatial and temporal control over biochemical and physical properties. The goal of this thesis is to leverage thiol-norbornene click chemistry, a subtype of photo-click chemistry, to develop 3D hydrogels with biochemical and biophysical cues that guide mesenchymal …

Understanding The Experiences Of Secondary Students Identified As In-School Truant And Their Perceived Contributing Factors To Truancy: When And What Caused The Disconnection, Joshua Donald Andres

Dissertations, Theses, and Projects

A strong correlation exists between school attendance and positive school outcomes such as increased graduation rates, stronger sense of belonging, and a higher grade-point average (Churchill et al., 2021; Daily et al., 2020; Allensworth & Easton, 2007). Therefore, school administrators implement strategies that foster positive attendance behavior for students. Attendance data is quantitative in nature and, while quantitative data is needed for decisions related to policy and best practices, qualitative data may better identify root causes of truancy behavior. This study’s purpose was to identify perceived contributing factors that resulted in participants having high rates of in-school truancy, or going …

Finger Movement Recognition Using Machine Learning Algorithms With Tree-Seed Algorithm, Muhammed Sami̇ Karakul, Ahmet Gökçen

Turkish Journal of Electrical Engineering and Computer Sciences

Electromyography (EMG) signals have been used to recognize various actions of hand movements, finger movements, and hand gestures. This paper aims to improve the classification accuracy of EMG signals while decreasing the number of features using the Tree-Seed Algorithm. The dataset containing EMG signals utilized in this investigation is derived from a publicly accessible source. The rationale for selecting the Tree-Seed Algorithm centers on its ability to enhance classification accuracy while minimizing the dimensionality of feature sets. The object function and Tree-Seed Algorithm's nature avoids the results to have low accuracy with fewer features. The aim is not just to …

Acute and chronic stress each have physical manifestations in the human body that can lead to many negative health impacts. Today, reported stress levels worldwide are at an all-time high, spurring the search for non-pharmaceutical interventions to maintain healthy stress levels. In this study, we examined whether a pet dog’s presence influences healthy adults’ acute stress responses as assessed through self-reports, heart rate, plasma cortisol, and salivary alpha-amylase. Participating pet dog owners were randomly assigned to undergo the Trier Social Stress Test either with their pet dog or alone. While there was no group difference in perceived anxiety levels, participants …

Advances In Hodgkin Lymphoma: Diagnosis Characteristics And Molecular Approaches, Xiaomin Peng, Ms Sep 2024

Advances In Hodgkin Lymphoma: Diagnosis Characteristics And Molecular Approaches, Xiaomin Peng, Ms

Student Papers, Posters & Projects

Hodgkin Lymphoma (HL) is a B-cell lymphoma with two distinct entities: classical Hodgkin Lymphoma (cHL) and Nodular Lymphocyte Predominant Hodgkin Lymphoma (NLPHL). Based on different tumor microenvironments, cHL is divided into four subtypes: Nodular Sclerosis CHL (NSCHL), Mixed Cellularity CHL (MCCHL), Lymphocyte-Depleted CHL (LDCHL), and Lymphocyte-Rich CHL (LRCHL). cHL and NLPHL have similar histology features, low concentration of malignant cells within abundant inflammation, the most significant difference is the molecular profiles of Reed-Sternberg (RS) cells and Lymphocyte Predominant (LP) cells. HL has a high cure rate with frontline treatment, but a small percentage of patients do not achieve treatment success, …

Tooth Type And Position In A Hypothetical Pectinodon..., Keith Snyder, Jonathon Campos, Neal Doran, Charity Simmons

Achieve

In 1856, Leidy rst identied Troodontidae as a taxonomic unit. It was not until 1945 that C.M. Sternberg assigned it to a family status. There has been much debate on taxonomic naming in this family, but in 1987, Currie conated all previous names into a single species, Troodon formosus. On the basis of isolated teeth, Carpenter (1982) suggested a second species, Pectinodon bakkeri from the Lance Formations. With limited specimens (24), Longrich (2008) proposed tooth positioning for the 4 tooth types he dened. This was especially challenging since no cranial or post-cranial skeletal structures have yet been identied.

Effects Of Microplastic Biofilms On An Anthropogenically Impacted Suburban Lake, Paris M. Velasquez

Masters Theses

Plastics have been observed in every location on the planet, and their prevalence in the environment is due in part to their strong resistance to degradation. Inland lakes are susceptible to plastic pollution by highway runoff, which contains plastic fragments of brake pads, car tires, litter, and road paint. These plastics eventually enter freshwater environments and degrade into microplastics (

Department of Biochemistry and Molecular Biology Faculty Papers

The chromatin-remodeling enzyme helicase lymphoid-specific (HELLS) interacts with cell division cycle-associated 7 (CDCA7) on nucleosomes and is involved in the regulation of DNA methylation in higher organisms. Mutations in these genes cause immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome, which also results in DNA hypomethylation of satellite repeat regions. We investigated the functional domains of human CDCA7 in HELLS using several mutant CDCA7 proteins. The central region is critical for binding to HELLS, activation of ATPase, and nucleosome sliding activities of HELLS-CDCA7. The N-terminal region tends to inhibit ATPase activity. The C-terminal 4CXXC-type zinc finger domain contributes to CpG …

Introduction

Total joint arthroplasty (TJA) remains highly prevalent, nearly rivaling the prevalence of other challenging conditions such as heart failure. Annually, there are over 790,000 total knee replacements and more than 450,000 hip replacements performed in the United States. As the demand for TJAs steadily increases, issues related to access, and quality have become increasingly pronounced. Despite the significant annual rise in volume of surgeries, there exists a notable gap pertaining to the epidemiology and reimbursement rates of TJAs within the United States.

Methods

Publicly available data from the Centers for Medicare & Medicaid Services Database was extracted. The dataset …

Metadegron: Multimodal Feature-Integrated Protein Language Model For Predicting E3 Ligase Targeted Degrons, Mengqiu Zheng, Shaofeng Lin, Kunqi Chen, Ruifeng Hu, Liming Wang, Zhongming Zhao, Haodong Xu

Faculty, Staff and Student Publications

Protein degradation through the ubiquitin proteasome system at the spatial and temporal regulation is essential for many cellular processes. E3 ligases and degradation signals (degrons), the sequences they recognize in the target proteins, are key parts of the ubiquitin-mediated proteolysis, and their interactions determine the degradation specificity and maintain cellular homeostasis. To date, only a limited number of targeted degron instances have been identified, and their properties are not yet fully characterized. To tackle on this challenge, here we develop a novel deep-learning framework, namely MetaDegron, for predicting E3 ligase targeted degron by integrating the protein language model and comprehensive …

BACKGROUND: Hyperactivated protein arginine methyltransferases (PRMTs) are implicated in human cancers. Inhibiting tumor intrinsic PRMT5 was reported to potentiate antitumor immune responses, highlighting the possibility of combining PRMT5 inhibitors (PRMT5i) with cancer immunotherapy. However, global suppression of PRMT5 activity impairs the effector functions of immune cells. Here, we sought to identify strategies to specifically inhibit PRMT5 activity in tumor tissues and develop effective PRMT5i-based immuno-oncology (IO) combinations for cancer treatment, particularly for methylthioadenosine phosphorylase (MTAP)-loss cancer.

METHODS: Isogeneic tumor lines with and without MTAP loss were generated by CRISPR/Cas9 knockout. The effects of two PRMT5 inhibitors (GSK3326595 and MRTX1719) were …


Toward Standardized Brain Tumor Tissue Processing Protocols In Neuro-Oncology: A Perspective For Gliomas And Beyond, Manmeet Ahluwalia, Michael Mcdermott Sep 2024

Toward Standardized Brain Tumor Tissue Processing Protocols In Neuro-Oncology: A Perspective For Gliomas And Beyond, Manmeet Ahluwalia, Michael Mcdermott

All Publications

Implementation of standardized protocols in neurooncology during the surgical resection of brain tumors is needed to advance the clinical treatment paradigms that use tissue for diagnosis, prognosis, bio-banking, and treatment. Currently recommendations on intraoperative tissue procurement only exist for diffuse gliomas but management of other brain tumor subtypes can also benefit from these protocols. Fresh tissue from surgical resection can now be used for intraoperative diagnostics and functional precision medicine assays. A multidisciplinary neuro-oncology perspective is critical to develop the best avenues for practical standardization. This perspective from the multidisciplinary Oncology Tissue Advisory Board (OTAB) discusses current advances, future directions, …

Arousal and motivation interact to profoundly influence behavior. For example, experience tells us that we have some capacity to control our arousal when appropriately motivated, such as staying awake while driving a motor vehicle. However, little is known about how arousal and motivation jointly influence decision computations, including if and how animals, such as rodents, adapt their arousal state to their needs. Here, we developed and show results from an auditory, feature-based, sustained-attention task with intermittently shifting task utility. We use pupil size to estimate arousal across a wide range of states and apply tailored signal detection theoretic, hazard function …

Recent advances in human genetics have shed light on the genetic factors contributing to inflammatory diseases, particularly Crohn's disease (CD), a prominent form of inflammatory bowel disease. Certain risk genes associated with CD directly influence cytokine biology and cell-specific communication networks. Current CD therapies primarily rely on anti-inflammatory drugs, which are inconsistently effective and lack strategies for promoting epithelial restoration and mucosal balance. To understand CD's underlying mechanisms, we investigated the link between CD and the FGFR1OP gene, which encodes a centrosome protein. FGFR1OP deletion in mouse intestinal epithelial cells disrupted crypt architecture, resulting in crypt loss, inflammation, and fatality. …

School of Integrative Biological & Chemical Sciences Faculty Publications

Background

Bioacoustic monitoring is an effective and minimally invasive method to study wildlife ecology. However, even the state-of-the-art techniques for analyzing birdsongs decrease in accuracy in the presence of extraneous signals such as anthropogenic noise and vocalizations of non-target species. Deep supervised source separation (DSSS) algorithms have been shown to effectively separate mixtures of animal vocalizations. However, in practice, recording sites also have site-specific variations and unique background audio that need to be removed, warranting the need for site-specific data.

Methods

Here, we test the potential of training DSSS models on site-specific bird vocalizations and background audio. We used a …


Enduring Heroism In The Face Of Inequality And Injustice: Who Steps Up And Why?, Carol D. Ryff Sep 2024

Enduring Heroism In The Face Of Inequality And Injustice: Who Steps Up And Why?, Carol D. Ryff

Heroism Science

Enduring heroism defined as persistent efforts to confront inequality and injustice is the focus of this article. Six exemplars are considered: Harriet Tubman, Crazy Horse, Jane Addams, Mohandas Gandhi, Nelson Mandela, Malcolm X. Similarities and differences in their pursuits are considered and linked to the larger literature on heroism. They are also contrasted with enduring anti-heroes to elevate roles of virtue and benevolence in long-term efforts to correct societal ills. What motivates enduring heroism is a central question. A hypothesis put forth is that distinct dimensions of eudaimonic well-being – especially, purpose in life, autonomy, environmental mastery, and personal growth …

Tree Diversity Across The Minneapolis-St. Paul Metropolitan Area In Relation To Climate And Social Vulnerability, Adrienne B. Keller, Leslie A. Brandt, Jeannine Cavender-Bares, Joseph F. Knight, Sarah E. Hobbie Sep 2024

Tree Diversity Across The Minneapolis-St. Paul Metropolitan Area In Relation To Climate And Social Vulnerability, Adrienne B. Keller, Leslie A. Brandt, Jeannine Cavender-Bares, Joseph F. Knight, Sarah E. Hobbie

Michigan Tech Publications

Urban tree canopy cover is often unequally distributed across cities such that more socially vulnerable neighborhoods often have lower tree canopy cover than less socially vulnerable neighborhoods. However, how the diversity and composition of the urban canopy affect the nature of social-ecological benefits (and burdens), including the urban forest's vulnerability to climate change, remains underexamined. Here, we synthesize tree inventories developed by multiple organizations and present a species-specific, geolocated database of more than 600,000 urban trees across the 7-county Minneapolis-St. Paul (MSP) metropolitan area in the Upper Midwest of the United States. We find that tree diversity across the MSP …

Horticulture Faculty Publications and Presentations

Spring dead spot (Ophiosphaerella spp.; SDS) is one of the most detrimental diseases to warm-season turfgrasses, particularly bermudagrass (Cynodon spp.), growing in climates where cold temperatures induce dormancy. The pathogen can infect the crowns, stolons, rhizomes, and roots of bermudagrass most of the year, but infection in the fall predisposes the turf to winter injury and plant death. Symptoms typically appear the following spring, making management of SDS challenging. Moreover, the biology, epidemiology, and management of SDS are not fully understood. Ample research has been conducted on SDS which was thoroughly summarized before 2009 by Tredway et al. …


Melanism In Polymorphic Terrestrial Snakes: A Meta-Analysis And Systematic Review, Ryan A. Martin Sep 2024

Melanism In Polymorphic Terrestrial Snakes: A Meta-Analysis And Systematic Review, Ryan A. Martin

Faculty Scholarship

Background and Aim: Colour polymorphic populations constitute excellent model systems for testing ecological and evolutionary hypotheses, as alternate colourations are associated with differences in various biological, behavioural and life-history traits. Melanism is the most common and most obvious form of polymorphism. In reptiles in general (and snakes in particular), thermal melanism has been a popular hypothesis used to explain the appearance of black individuals. It suggests that a trade-off exists between superior thermoregulation and reduced protection through the loss of crypsis. Surprisingly, despite the growing body of literature available, to date, there are only two qualitative reviews on the evolutionary …

Although all hexose sugars share the same chemical formula, C6H12O6, subtle differences in their stereochemical structures lead to their various biological roles. Due to their prominent role in metabolism, hexose sugars are commonly found in nanoconfined environments. The complexity of authentic nanoconfined biological environments makes it challenging to study how confinement affects their behavior. Here, we present a study using a common model system, AOT reverse micelles, to study hexose sugars in nanoconfinement. We examine how reverse micelles affect the hexoses, how the hexoses affect reverse micelle formation, and the differences between specific hexoses: glucose, mannose, and galactose. We find …

Coral reefs, despite covering less than 0.2 % of the ocean floor, harbor approximately 35 % of all known marine species, making their conservation critical. However, coral bleaching, exacerbated by climate change and phenomena such as El Niño, poses a significant threat to these ecosystems. This study focuses on the Red Sea, proposing a generalized machine learning approach to detect and monitor changes in coral reef cover over an 18-year period (2000–2018). Using Landsat 7 and 8 data, a Support Vector Machine (SVM) classifier was trained on depth-invariant indices (DII) derived from the Gulf of Aqaba and validated against ground …
