Mathematical Practices (Commonly Used By Mathematicians) In Mathematics Teachers’ Solutions To Algebraic Problems, Vesife Hatisaru, Steven Richardson, Jon R. Star

Research outputs 2022 to 2026

A teacher of mathematics knows mathematics as a teacher and as a mathematician. Whilst the existing research on teacher knowledge contributes to our understanding of the ways of knowing mathematics as a teacher, little is known about ways of knowing mathematics as a mathematician. Guided by the conceptual framework of mathematical practices (MPs) (commonly used by mathematicians), this case study aimed to contribute to fill this gap. The study examined solutions generated by two secondary teachers of mathematics to a set of algebraic problems to determine which MPs are apparent, or not, in the teachers’ work. Data were content analyzed …

Sacred Or Sacrificed Placemaking: A Contested Fan Pilgrimage Site For Rural Tourism Development, Timo Thelen, Sangkyun Kim, Tomohiro Kai, Eerang Park

Research outputs 2022 to 2026

The concept of placemaking describes the transformation and development of a site directed by the local authorities. This longitudinal study examines the emergence of a fan pilgrimage site in rural Japan and the subsequent placemaking process to establish it as a popular culture tourism site. The study uncovers friction among stakeholders and backlash against the top-down placemaking approach from both residents and fans, whose attitudes are more critical and impactful than those of non-fan tourists towards making the place. The study contributes to a nuanced understanding of placemaking dynamics and complexity by drawing on a non-Western context and its particularities, …

Environmentally Persistent Free Radicals Lead To Selective Inhibition Of Cyp1 Monooxygenase Activities, And Increased Production Of Reactive Oxygen Species By Reaction Uncoupling, John Patrick Connick, Amari A. Stepter, George F. Cawley, Marilyn K. Eyer, Wayne L. Backes

School of Medicine Faculty Publications

This study focuses on the effect of Environmentally Persistent Free Radicals (EPFRs) on the P450 enzymes of the CYP1 family. EPFRs are a component of particulate pollutants, that are stable in the environment, but can generate free radicals, leading to oxidative stress and subsequent toxicity of the respiratory, cardiovascular, and immune systems once they enter an organism. The results show differences in the ability of EPFRs to inhibit CYP1-dependent substrate metabolism, with CYP1B1 being inhibited to the greatest extent. There also were differences in the ability of EPFRs to disrupt the POR•CYP1 complex, with CYP1B1 being the only form where …

Chronic Administration Of A Cannabis-Derived Mixture At An Antihyperalgesic Dose Does Not Significantly Enhance Hepatotoxicity Or The Development Of Metabolic Dysfunction-Associated Steatohepatitis In Male Mice, Kim B. Pedersen, Tomislav Jelesijevic, Tamara M. Morris, Sarah M. Melton, Ashley S. Henderson, John F. Glenn, Gregory J. Davenport, Martin J.J. Ronis, Peter J. Winsauer

School of Medicine Faculty Publications

Cannabis and cannabinoid mixtures have been linked to a variety of health benefits including pain mitigation, suppression of nausea produced by chemotherapeutic agents, anti-inflammatory effects, and effects on energy homeostasis, glucose, and lipid metabolism. The latter properties have led to the suggestion that these products could have therapeutic effects on the development of metabolic dysfunction-associated steatohepatitis (MASH) - a severe type of liver pathology in obese and diabetic patients. However, varying agonist and antagonistic properties of different cannabinoids on the endogenous cannabinoid system make prediction regarding hepatic effects and diet interactions difficult. The current study was designed to examine hepatic …

Roles Of Basic Fibroblast Growth Factor, Stem Cells From Dental Pulp And Apical Papilla In The Repair And Regeneration Of Dental Pulp And Other Tissues/Organs, Jiiang-Huei Jeng, Pin-Hsuan Wu, Yan-Hsiung Wang, Ying-Chu Lin, Ya-Shuan Chou, Mei-Chi Chang

Journal of Dental Sciences

Abstract Currently, the concept of regeneration and regenerative therapies are already being applied clinically to treat pulpal and periodontal diseases, as well as to repair and regenerate systemic organs and tissues. During wound healing, well-developed, functional vascular networks and revascularization are fundamental factors in restoring regenerative potential. Growth factors, stem cells, and scaffolds alone or in combination are reported to contribute to successful tissue repair and engineering via cell transplantation, cell homing or other technologies. Among the growth factors, basic fibroblast growth factor (bFGF) has been found to regulate the proliferation, stemness, migration, and differentiation of vascular and mineralized tissues …

Evidence For Alcohol-Mediated Hemolysis And Erythrophagocytosis, Chaowen Zheng, Siyuan Li, Johannes Mueller, Cheng Chen, Huanran Lyu, Guandou Yuan, Ane Zamalloa, Lissette Adofina, Parthi Srinivasan, Krishna Menon, Nigel Heaton, Stephan Immenschuh, Ines Silva, Vanessa Rausch, Seddik Hammad, Steven Dooley, Shilpa Chokshi, Antonio Riva, Songqing He, Sebastian Mueller

Peninsula Medical School

Alcohol-related liver disease (ALD) is the most common liver disease worldwide; however, its underlying molecular mechanisms remain poorly understood. Here, we identify ethanol-mediated hemolysis and erythrophagocytosis as major contributors to ALD pathogenesis using both in vitro and in vivo models, as well as surrogate markers such as heme oxygenase-1 (HO-1) and CD163, a scavenger receptor for hemoglobin-haptoglobin complexes. A key initial observation was the direct optical evidence of serum hemolysis in heavy drinkers, which diminished after one week of alcohol withdrawal. In parallel, soluble CD163 (sCD163) levels declined during alcohol detoxification correlating with liver damage and fibrosis stages. Moreover, red …

Is Sparse Local Ecological Knowledge Accurate Enough For Policy? A Seagrass Mapping Case Study From Five Greek Islands In The Eastern Aegean Sea, Konstantis Alexopoulos, Tim J. Grandjean, Anastasia Miliou, Theodoros Tsimpidis, Abigail Mcquatters-Gollop

School of Biological and Marine Sciences

The low cost, high applicability and community-based nature of Local Ecological Knowledge (LEK) data for mapping marine benthic habitats has become increasingly popular in recent years. Nonetheless, due to persisting technocratic distrust of LEK often stemming from the unquantifiable nature of bias, the embedding of empirical data at policy levels often lags. Currently, protocols rely on high participation from stakeholders, however, such quotas are often unfeasible, with common limiting factors being the low numbers of knowledgeable individuals in remote parts of the world, and the lack of community trust in the conservation mechanism. In this study, we test whether data …

Organoid In Dentistry: Models For Oral Biology And Disease, Wei-Jen Chang, Tomomi Sano, Ting-Yi Renn, Takashi Kanematsu, Ming-Shou Hsieh, Chia-Chen Hsu

Journal of Dental Sciences

Abstract Cell lines and animal models have long been used as essential tools in studies targeting the oral cavity, offering valuable insights into various oral diseases. Each of these research models provides its advantages, such as ease of manipulation in cell lines and the ability to replicate whole–organ interactions in animal models. However, conventional models often have limited native phenotypic features, which do not fully capture the complexity of the human oral cavity. In response to these limitations, organoid technologies have recently been developed and emerged as a promising alternative. Organoids, which are widely applied to mimic the complexity of …

Developing An Artificial Intelligence Framework For Identifying Fusion Blood-Based Biomarkers In Alzheimer's Disease, Ali H. Al-Nuaimi, Mohammed Kamal Nsaif, Shaymaa Al-Juboori

School of Engineering, Computing and Mathematics

Alzheimer’s Disease (AD) is an irreversible neurological disorder, a major cause of disability among the elderly, with no effective therapeutic options currently available. It is an asymp-tomatic disease in the prodromal stages and begins many years before clinical appearances. Early diagnosis of AD allows patients to obtain appropriate healthcare assistance, accelerating the development of new medications. A biomarker that evaluates the alterations in the brain cells produced by AD in its preliminary periods might be significant for its early identification. Blood-based biomarkers (BBBMs) facilitate the early detection of AD. The BBBMs detection procedure is cost-efficient and minimally invasive. The aim …

Diaspora Politics And A Rising China: Ambivalent Ties Amid Geopolitical Changes, Jiaqi M. Liu

Research Collection School of Social Sciences

Over the past decade, the rise of China on the global stage has witnessed the emergence of members of the Chinese diaspora as new meso-level actors in mediating Sino-Western relations. As part of China’s burgeoning “public diplomacy” around the globe, Chinese migrants organize cultural events to establish grassroots and semi-official exchanges between China and the West. This chapter provides a state-of-the-art examination of so-called “diasporic public diplomacy” whereby the Chinese diaspora plays an increasingly important role in promoting China’s soft power abroad. Based on long-term fieldwork in a prominent emigrant community, I analyse how Chinese national policies envision two specific …

The Fiction Of Possibility: How Possible Worlds Theory Explains The Impossible Worlds Of Science Fiction, Jacob Burlingame

Graduate Research Theses & Dissertations

This dissertation explores the ways that science fiction texts convey to the reader the worlds in which they are set. It identifies four main strategies through which a science fiction text conveys its world: Neologisms, Secondary Texts, Actual-World Analogs, and Exposition. Neologisms include any words that are coined by the author to describe an entity that only exists in the text world, which creates a fuller world by creating a referent for them. Secondary Texts are any other documents alluded to by the primary text, whether created for the text world or imported from the actual world; these secondary texts …

Functional Characterization Of The Hdt5 Gene In Aspergillus Flavus Morphogenesis, Mycotoxin Production, And Fungal Phytopathogenicity, Brenda Omburo

Graduate Research Theses & Dissertations

The present study aimed at elucidating the role of hdt5 in fungal morphology, mycotoxin production and in plant virulence in Aspergillus flavus. Currently, methodologies to prevent the negative impact of A. flavus are insufficient. It is known that expression of the hdt5 gene is dependent on hbx1, a master regulatory gene that affects expression of hundreds of genes in the A. flavus genome, controlling both development and secondary metabolism. However, while the aflatoxin gene cluster has been elucidated, the genetic regulatory mechanisms controlled by hdt5 are not fully understood. For this study, therefore, a complete strain set composed of a …

An Exploration Of Social Isolation’S Effects On The Gastrointestinal And Metabolic Health Of A Social Mammal, Daniel Adam Nuccio

Graduate Research Theses & Dissertations

Human health can be impacted considerably by subjective feelings of loneliness, resulting in mental illness and the dysregulation of normal cardiovascular, immune and endocrine functioning. This occurs because social isolation serves as a form of chronic stress for social mammals, spurring physiological responses akin to those associated with more standard forms of stress. On account of their highly social nature, prairie voles (Microtus ochrogaster) subsequently have become one of the model organisms of choice for investigating the effects of social isolation on the development of disease in social mammals.

This dissertation seeks to expand the scientific community’s understanding of the …

Perspectives On Demyelinating Disease: An Overview Of Multiple Sclerosis, Nathaniel Howard Williams

Senior Honors Theses

Multiple sclerosis (MS) is a demyelinating disease of central nervous system (CNS), primarily concerning oligodendrocytes, the myelinating cells of the CNS and the neurons that are ensheathed in myelin. MS is the most common demyelinating disease, affecting as many as 300,000 yearly in the United States alone. Much debate centers on whether MS onset is primarily caused by autoimmune reactions or intrinsic dysfunction in oligodendrocytes, which prompts an immune-mediated response. Those who review the current literature on MS may become quickly overwhelmed by the volume and variety of available material. The purpose of this review is to present a …
