Specifically Targeting Muc16 For Fluorescence-Guided Surgery Of Pancreatic Ductal Adenocarcinoma, Kathryn M. Muilenburg

Theses & Dissertations

Pancreatic cancer is a lethal disease with a low 5-year survival rate and a high rate of resection recurrence. However, surgery remains the only treatment with curative potential for pancreatic cancer. Many factors such as high desmoplasia, a lack of intraoperative imaging, and micrometastatic disease contribute to the high rate of incomplete resections in pancreatic cancer. Fluorescence-guided surgery (FGS) is a potential intraoperative tool for application in surgical resection. FGS works through passive or active targeting of a free dye or dye-containing moiety (e.g. antibody, peptide, and nanoparticles) to specifically fluoresce the tumor compared to the surrounding normal, fibrotic, and …

Bone-Ivd Crosstalk And The Role Of Rage Signaling In An Ivd Injury Model, Remy Walk

McKelvey School of Engineering Graduate Student Theses & Dissertations

Low back pain (LBP) is the number one musculoskeletal cause of disability with a lifetime prevalence of up to 85%. The causes of LBP are multifactorial with potential contributions from factors such as tissue injury and degeneration as well as social economic and psychological factors. Intervertebral disc (IVD) degeneration is associated with 26-40% of LBP cases and in a 2015 meta-analysis, it was estimated that a total 403 million people suffer from symptomatic IVD degeneration. IVD degeneration is characterized by loss of hydration in the nucleus pulposus (NP), damage accumulation in the annulus fibrosus (AF) and calcification of the cartilaginous …

Development Of Computational Imaging Pipelines To Advance Quantitative Co-Clinical Imaging And Pathology, Kaushik Dutta

McKelvey School of Engineering Graduate Student Theses & Dissertations

Deep learning driven computational methods have profoundly impacted medical imaging by advancing feature extraction, and by establishing a critical foundation for downstream image analysis and interpretation. Co-clinical trials are an emerging area of investigation in which a clinical trial is coupled with a corresponding preclinical study to inform the corresponding clinical trial to enhance translational accuracy and therapeutic development. Within this framework, quantitative imaging and pathology plays a fundamental role in both clinical and preclinical arms of co-clinical trials. Quantitative imaging enables enabling identification and validation of imaging biomarkers which are leveraged to predict therapeutic response, characterize disease phenotypes, and …

Quantitative Approaches To Dissect Bivalent Antibody Binding And Detect Viruses From Aerosolized Samples, Ananya Benegal

McKelvey School of Engineering Graduate Student Theses & Dissertations

Influenza A virus (IAV) poses substantial epidemiological burdens around the world, with an estimated annual global mortality rate in the hundreds of thousands. Its rapid rate of mutation gives it a propensity for causing seasonal epidemics and occasional pandemics. As an airborne virus, IAV is most commonly transmitted through droplets and aerosols. Antibodies play a crucial role in the immune defense against IAV infection. By understanding the mechanisms of antibody-mediated defense and the transmission dynamics of IAV, we can better inform strategies for prevention, vaccination, and treatment, ultimately mitigating its impact on public health. The work encompassed in this dissertation …

Defining The Chondrocyte “Mechanome”: How Mechanosensitive Ion Channels Trpv4 And Piezo1 Drive Changes In Gene Expression To Affect Cell Behavior And Cartilage Health, Daniel Raymond Palmer

McKelvey School of Engineering Graduate Student Theses & Dissertations

Chondrocytes, the only native cell population of cartilage, utilize mechanosensitive transmembrane ion channels to sense mechanical forces. Transient Receptor Potential Vanilloid 4 (TRPV4) is activated by physiologic levels of load (resulting in ~10% tissue deformation) while PIEZO1 is activated by supraphysiologic levels of load (resulting in >50% tissue deformation). TRPV4 activation promotes the expression of a limited number of chondrogenic genes and the production of vital cartilaginous matrix proteins, while PIEZO1 activation drives cell death and senescence, cytoskeletal weakening, and production of catabolic mediators, which contribute to the development of osteoarthritis (OA). However, the path connecting activation of these channels …

The Encoding Of Decision Variables In Orbitofrontal Cortex (Ofc) Is Longitudinally Stable And Varies By Cortical Layer, Manning Zhang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Economic choices entail computing the values of different options and then making choice by comparing values. Work in primates and rodents has shown that these mental processes rely on the OFC. Neurophysiology studies identified in OFC distinct groups of neurons encoding the value of individual options, the binary choice outcome, and the chosen value. These variables capture both the input and the output of the decision process, suggesting a decision circuit existing in OFC. A primary challenge for the field is to assess the structure and mechanisms governing this circuit. A first fundamental question is whether the circuit is stable …

Spatial Insight Of Kidney Sex-Dimorphism And Tumor Evolution, Chia-Kuei Mo

McKelvey School of Engineering Graduate Student Theses & Dissertations

The landscape of spatial biology research has transformed drastically in recent years allowing a comprehensive understanding of cellular organization and molecular mechanisms in various biological context. This thesis presents three complementary studies that advance our understanding of spatial organization in normal tissue biology and tumor evolution, utilizing cutting-edge spatial multi-omics approaches. The first study presents a comprehensive investigation of kidney sexual dimorphism across the lifespan, integrating six distinct technological platforms: single-nucleus transcriptomics, epigenomics, Visium spatial transcriptomics, Xenium single-cell resolution spatial transcriptomics, conventional immunofluorescence imaging, and co-detection by indexing (CODEX) multiplexed protein imaging. This multi-modal approach reveals that proximal tubules exhibit …

Development Of Platform And Harness System For In Vivo Rat Elbow Range Of Motion Device And Confirmation Of Ulnar Nerve Integrity In Rats, Genevieve Jarrell

Mechanical Engineering and Materials Science Independent Study

This independent study in Dr. Lake’s Musculoskeletal Soft Tissue Lab focused on two main projects. The first was creating a platform and harness system to secure a rat while its elbow range of motion (ROM) was measured in vivo. Multiple prototypes were designed, 3D printed, and tested on a deceased animal, and each design was improved upon to yield more consistent results. The final prototype yielded semi-consistent results, with further improvements identified and planned. The second project focused on developing a protocol to confirm the integrity of a rat’s ulnar nerve after an ulnar collateral ligament (UCL) transection. Two methods …

Re-Indigenizing And Collaboratively Tending Urban Greenspaces, Divinity Nnenne Adewale

University Honors Theses

This work details the active process of land tending with the intention of re-Indigenization in the Pacific Northwest at several Portland sites; The Native American Student Community Center, PSU Oak Savanna, and the Ridgefield National Wildlife Refuge. Land tending is an intuitive process, one rooted in love and respect for life of all forms as well as becoming the perpetual student; land tending is not a skill to be mastered, only practiced. Unlike environmental management, tending cannot be done separate from the earth, in a classroom or otherwise. Connections are what tending is built on top of: the foundation; effort …

Obesity and type 2 diabetes mellitus (T2DM) are chronic diseases with increasing prevalence, underscoring the urgent need for effective treatment and management strategies. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have emerged as an essential class of drugs for managing both obesity and T2DM, offering additional benefits for cardiovascular and kidney health. GLP-1 RAs work by targeting GLP-1 receptors, mimicking the effects of the natural hormone GLP-1 to regulate blood glucose levels, promote weight loss, and provide potential benefits for cardiovascular health. This narrative review evaluates the mechanisms of action, clinical efficacy, and broader roles of GLP-1 RAs in promoting weight …

Revisiting Territorial Sovereignty: Origins, Legitimacy, And Modern Implications, Henan Hu

San Diego International Law Journal

The conventional linkage between territory and sovereignty in international law requires reevaluation, with territorial rights shifting from states to nations. Drawing on Anthony Smith’s theory of historical continuity between pre-modern ethnic communities and modern nations, this article argues that legitimate claims to territory are grounded in the historical consolidation of social, economic, and political ties by ethnic groups to specific lands. It traces the evolution of territorial rights from loosely defined ethnic living areas and fluid state boundaries to the modern conception of national territories under effective control. By distinguishing sovereignty as a construct of the state and territory as …

Beyond Bindis, Bhajis, Bangles And Bhangra: Promoting Multiculturalism In Primary Schools In Predominantly White British Places, Suparna Bagchi

School of Law, Humanities and Social Sciences

Twenty-first-century education as a powerful means of knowledge will possibly be shaped by the emphasis it places on having classrooms that are race-conscious and multicultural. The present article is based on a doctoral study that explores an under-researched area: experiences and understanding of multiculturalism in mainstream primary schools situated in the predominantly White places of Southwest England. The study was underpinned by a sociocultural theoretical framework; data were collected through semi-structured interviews with the adult participants, students’ classroom activities, and documentary analysis of school displays. The article focuses on the data generated from the students’ classroom activities. Findings show differences …

Climatic oscillations are considered primary factors influencing the distribution of various life forms on Earth. Large species adapted to cold climates are particularly vulnerable to extinction due to climate changes. In our study, we investigated whether temperature increase since the Late Pleistocene and the contraction of environmental niche during the Holocene were the main factors contributing to the decreasing range of moose (Alces alces) in Europe. We also examined whether there were significant differences in environmental conditions between areas inhabited by moose in Europe and Asia, that could support the division of moose into western and eastern forms, as suggested …

Action Logic And Agenda Game Of Global Methane Emission Control And China’S Countermeasures, Bo Zhang, Jinling Guo, Bing Zhong, Junlian Gao, Guosheng Zhang, He Liu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Originated from the global response to climate change, methane emission control has evolved into a focus of international climate negotiations in recent years. At present, the agenda for controlling methane emission in global climate governance is basically taking shape, but in the process of shifting from scientific consensus to political consensus, the content of the topic and the focus of the game continue to evolve. To carry out global action, it is necessary to address issues such as the allocation of responsibilities, international rules, climate investment and financing, and risk prevention, as well as the basic capacity guarantees behind them. …

Bile Acids In Inflammatory Bowel Disease: From Pathophysiology To Treatment, Samantha H Bai, Arun Chandnani, Siyan Cao

2020-Current year OA Pubs

Inflammatory bowel disease (IBD) is a chronic condition that affects about 7 million people worldwide, and new therapies are needed. Understanding the complex roles that bile acids (BAs) play in IBD may lead to the development of novel IBD treatments independent of direct immunosuppression. This review discusses the latest discoveries in the roles BAs play in IBD pathogenesis and explores how these discoveries offer promising new therapeutic targets to treat IBD and improve patient outcomes. Several therapies discussed include specific BA receptor (BAR) agonists, dietary therapies, supplements, probiotics, and mesenchymal stem cell therapies that have all been shown to decrease …

Subaltern Planet Of Cultural Studies, Charlie Samuya Veric

Kritika Kultura

A contribution to a mostly unwritten history, the essay provides a preliminary account of cultural studies in Asia, Africa, and Latin America from decolonization to globalization. My intention is two-fold, namely, to contribute to the history of cultural studies in the global South and experiment with the writing of planetary history to determine the lessons that can be learned when totality is imagined from below. I argue that whether it is the geopolitics of decolonization in Asia, the politics of indigenization in Africa, or the critique of knowledge-production in Latin America, cultural studies signifies the unfinished task of decolonization.

Primates In Paradise: Critical Possibilities Of The Milieu Movie, Joel David

Kritika Kultura

The use of multiple lead characters in cinema is a fairly recent development, although the strategy (and its resultant variety of structures) had been present for some time in theater and literature. The typical Classical Hollywood action-driven narrative operated most efficiently through a singular hero, allowing the audience to undergo the film experience via the process of singular identification. With the breakdown in identificatory requisites popularized by various New Wave and Third Cinema movements, and the consequent assimilation of this trend starting with the New American Cinema, mainstream Hollywood was ready to embark upon a series of multi-character movies, with …

Sisa's Vengeance: Rizal And The Mother Of All Insurgencies, E. San Juan Jr.

Kritika Kultura

A new appraisal of Rizal is needed today in the light of 9/11, the collapse of finance capital, state terrorism, and neoliberal decadence and barbarism. Rizal’s revolutionary critique can be discovered by shifting the center of inquiry to the Dapitan years and after, the Liga’s resonance, and the Sisa-Maria Clara-Salome nexus. By exposing the limits of Simoun’s romantic idealism, Padre Florentino’s eschatological impulse, and the carnivalesque colonial world bereft of god/nomos, Rizal anticipates the post-capitalist predicament. Women’s vengeance against patriarchal nihilism lies submerged in Rizal’s communicative action to the Malolos collective, mobilizing emergent and residual historical forces in a dialectical …

Confession As A Narrative Mode In Gay Indie Films, Gary D. Devilles

Kritika Kultura

This paper is interested in confession as a narrative mode of media, specifically gay independent films, and the specific codes and mechanisms inherent in a confession that enable one to generate pity over the viewing public. I would discuss four gay indie films, Ang Lalaki sa Parola, Daybreak, Sagwan, and Selda, and look specifically at how these films use confession in their narration, as a cinematic style to develop their characters, and ultimately as a form of politics of viewing by which gay films in general become a sort of “public confession” constituting their viewers as their preferred “confessors.” Such …

The New Challenge Of The Mother Tongues: The Future Of Philippine Postcolonial Language Politics, T. Ruanni F. Tupas

Kritika Kultura

For much of postcolonial language politics around the world, the fight has largely been between a foreign (read: colonial) language and (a) dominant local language(s). This is true in the Philippines where the debates have focused on English and Filipino, the Tagalog-based national language. In recent years, however, the mother tongues have posed a challenge to the ideological structure of the debates. Although local languages have long been acknowledged as positively contributing to the enhancement of learning in school, they have been co-opted mostly as a nationalist argument against English, American (neo)colonialism and imperialist globalization. The current initiatives to establish …

The Effort To Promote Lichens For Human Consumption In Nineteenth-Century Europe, Michael E. Mitchell

European Journal of Food Drink and Society

In 1683 a lichen long relied in Iceland as a grain substitute was detected in Sweden, where chemical analysis revealed an appreciable nutritive content. Use of the lichen as food in Lapland was reported in the following century, but its composition was not again studied until the Spanish famine of 1805/6. The results of that investigation amply demonstrated the species’ potential as an emergency food, which led to lichens being recommended for domestic use and commercial bread production during successive European famines. Amateur attempts in France and Germany to distil alcohol from lichens proved uneconomic, a problem temporarily solved when …

Pickelfleisch, Pastirma, And Beyond: An Overview Of The Myths Of The Origin Of Pastrami, Angela Hanratty, Diarmuid Cawley

European Journal of Food Drink and Society

This paper investigates the assertion by Claudia Roden that pastrami is an invention of New York City delicatessens, a claim that refutes the accepted etymology of the word “pastrami” as being linked to a seasoned air-dried meat, sometimes referred to as basturma/pastirma, from Romania or Turkey. The probability that the roots of this iconic American delicatessen favourite can originally be found in two similar meats, pickelfleisch and homen, both originating from the areas today known as Alsace, France and the southeastern section of the German state of Rhineland-Palatinate will also be explored. Ashkenazi food culture is predominantly identified as having …

Pursuing Distinction: How Chinese Restaurants Leverage Cultural Capital To Ascend The Irish Culinary Hierarchy, Nan Xiang, Brian Murphy

European Journal of Food Drink and Society

Ethnic cuisine is typically positioned at the lower end of Western culinary hierarchy, in contrast to haute cuisine. Research to date has shown that in more recent decades, many ethnic restaurants in London and New York, including those specializing in Chinese cuisine, have successfully managed to transition into the previously unattainable high-end category. What is problematic, however, is the contrast between ethnic and haute cuisine, with ethnic as a restaurant category often being presented as lacking refinement and exuding an overriding sense of cheapness. Neither unrefined nor cheap, many ethnic restaurants, though not quite reaching the high-end, have gained significant …

“Weevils Floated On The Gravy”: Disgusting Food In African Fiction, Igor B. Cusack

European Journal of Food Drink and Society

This paper examines the uses of food in several African novels where descriptions of food might trigger the reader’s disgust. Visceral disgust might be elicited either by the senses, such as taste or smell, or by the nature and history of an object, that has been termed “ideational disgust." Visceral disgust differs from moral disgust, when an individual might feel something is profoundly wrong. Fictional descriptions of something disgusting may elicit similar emotions to those evoked by the material object, and this imagining has been called “the paradox of fiction." The reactions of individual readers may differ according to cultural …
