Addressing Hiv And Substance Use Health Disparities Among Racial/Ethnic Minority Individuals, Jamie V. Saunt, David L. Hussey

Faculty Scholarship

Purpose of Review: Advances in HIV testing, prevention, and treatment, alongside increased awareness and harm reduction efforts for substance use disorder (SUD) have improved care and treatment access over the past decade. However, racial and ethnic minorities with SUD and HIV or at risk for HIV still face disproportionately high health disparities. Understanding and addressing the reasons behind these disparities is crucial. Recent Findings: Structural and systemic barriers continue to negatively impact minoritized communities, due to lack of access to care, mistrust, and feelings of ostracization. Disconnected systems for HIV and SUD treatment complicate combined care. Delays in HIV diagnosis …

Computed Microtomographic Imaging Of Revascularization During Healing Of Achilles Tendon Injury, Seher Yilmaz, Ozan Akkus

Faculty Scholarship

Angiogenesis in injured tendons may contribute to regeneration, but quantifying it post-injury has been mostly limited to 2D semi-quantitative histology. This study aimed to develop micro-CT as a 3D tool to quantitatively assess tendon blood vessels in an experimental animal model. Adult male Wistar rats (N = 36) had injuries induced in their Achilles tendons by needle insertion. The study included three post-injury groups: 12 hours post-injury (12H), 3 weeks post-injury (3W), and 8 weeks post-injury (8W). The uninjured left Achilles tendon served as the control for each group. Intravital cardiac perfusion with barium sulfate enhanced contrast between tendon and …

Creatine Supplementation Is Safe, Beneficial Throughout The Lifespan, And Should Not Be Restricted, Richard Kreider, Andrew Jagim, Jose Antonio, Douglas Kalman, Chad Kerksick, Jeffrey R. Stout, Robert Wildman, Rick Collins, Diego A. Bonilla

Faculty Scholarship

As researchers investigating creatine supplementation, we have become increasingly concerned about reports that government agencies are attempting to restrict the sale of dietary supplements, including dietary supplements containing creatine, to children and adolescents. Creatine is a naturally occurring compound found in every cell in the human body that plays a critical role in cellular metabolism. The daily turnover of creatine is about 2–4 grams/day, depending on muscle mass and physical activity levels (1, 2). About half of the daily need for creatine is synthesized in the body from amino acids (arginine, glycine, methionine) and stored as free creatine or phosphocreatine …

Law And Historical Materialism, Jeremy K. Kessler

Faculty Scholarship

Since the financial crisis of 2008, left-leaning legal thought has experienced a renaissance within the American academy. From law and political economy to critical race theory to feminist legal studies to Marxist legal theory, new perspectives have flourished, and marginalized traditions have been revived and revised. These new perspectives and revisionist projects all share an intellectual debt to the critical legal studies (“CLS”) movement of the late 1970s and 1980s. That movement’s critique was focused on functional accounts of law: accounts that understood legal change as primarily responsive to the demands of extralegal social and economic forces. Some of those …

Disqualification, Immunity, And The Presidency, Gillian E. Metzger

Faculty Scholarship

Trump v. Anderson and Trump v. United States were two momentous decisions in a momentous Supreme Court term. Sharing then former — and now current — President Trump as a party, the decisions hold important implications for presidential power and accountability.

Anderson arose from a suit brought by Colorado voters to challenge Trump’s inclusion on the Republican primary ballot in that state. They argued that Trump organized and incited the mob that attacked the Capitol on January 6, 2021, and disrupted the Electoral College vote count and certification. In their view, this disqualified him from serving as President under section …

The Restatement Of Children And The Law: Modern Regulation In A Developmental Framework, Elizabeth S. Scott

Faculty Scholarship

In May 2024, the membership of the American Law Institute approved the Restatement of Children and the Law, the first Restatement to focus on the law regulating children and families. The combined efforts of five Reporters (Elizabeth Scott, Reporter, and Richard Bonnie, Emily Buss, Clare Huntington and Solangel Maldonado, Associate Reporters), working for almost nine years, this new Restatement covers most of the legal landscape of American law's relationship to children. It is organized in four Parts: Part I, Children in Families, deals with parental rights and authority and state intervention in families; Part II, Children in Schools, covers children's …

Artificial Intelligence, Autonomous Creation, And The Future Path Of Copyright Law, Peter K. Yu

Faculty Scholarship

Most literature at the intersection of copyright and AI has focused primarily on what copyright law is or ought to be. Frequently overlooked is the question of what copyright law will be in the AI space. Understanding this question is crucial because the path of copyright law chosen by the United States will have a major impact on the country's economic and technological future.

This article begins by scrutinizing two lines of arguments that have been advanced to deny copyright protection to AI-generated works: constitutional and incentive-based. The article then discusses a third line of arguments—harmonization-based arguments—and identifies select instances …

Response To Petition For Rehearing En Banc, Felicia M. Sonmez V. Wp Company Llc Et Al, Madeline H. Meth, Brian Wolfman, Becca Steinberg, Regina Wong, Elizabeth Brownstein, Nathaniel Allen Deacon

Faculty Scholarship

Felicia Sonmez alleges that the Washington Post violated the D.C. Human Rights Act by banning her from covering certain stories because she is a woman and a sexual-assault survivor. Op. 2-3. After finding Sonmez’s detailed allegations plausible, a panel of this Court rejected as premature the Post’s First Amendment defense that its decision was driven not by discrimination but by a desire to maintain an appearance of objectivity. Op. 4. Because “what actually motivated the Post editors to impose the bans on Sonmez is a factual question,” the panel held, the Post’s First Amendment defense could not be resolved on …

Promises, Promises: Understanding Claims Made In Social Robot Consumer Experiences, Johanna Gunawan, Sarah Elizabeth Gillespie, David Choffnes, Woodrow Hartzog, Christo Wilson

Faculty Scholarship

Social robots are a class of emerging smart consumer electronics devices that promise sophisticated experiences featuring emotive capabilities, artificial intelligence, conversational interaction, and more. With unique risk factors like emotional attachment, little is known on how social robots communicate these promises to consumers and whether they adequately deliver upon them within their overall product experiences prior to and during user interaction.

Animated by a consumer protection lens, this paper systematically investigates manufacturer claims made for four commercially available social robots, evaluating these claims against the provided user experience and consumer reviews. We find that social robots vary widely in the …

Science-Based Policy Recommendations For Managing Emerging Pollutants: Protecting Water Quality For The Health Of People And The Environment, Sarantuyaa Zandaryaa, Ali Fares, Gabriel Eckstein, Regina M. Buono, Mary Trudeau, James E. Nickum, Xingui Xia, Atikur Rahman, Marijn Korndewal, Cassiana C. Montagner, Piero R. Gardinali, Robert Michael Di Filippo, Anoop Veettil

Faculty Scholarship

Emerging water pollutants are a growing global concern due to their ubiquitous presence in water resources worldwide and their potential adverse effects on human health and ecosystems. Limited scientific understanding of sources of emerging pollutants’ emissions to water bodies and their pathways, behaviour, and fate in aquatic environments, as well as human health and ecological effects, is a significant hindrance in managing emerging water pollutants. With exceptions concerning PFAS/PFOS and microplastic beads, there are few regulations for emerging pollutants in national water and environmental policies, which results in a critical gap in safeguarding human health and aquatic ecosystems through effective …

Stable Heteroclinic Channels As A Decision-Making Model: Overcoming Low Signal-To-Noise Ratio With Mutual Inhibition, Natasha A. Rouse

Faculty Scholarship

Bio-inspired robot controllers are becoming more complex as we strive to make them more robust to, and flexible in, noisy, real-world environments. A stable heteroclinic network (SHN) is a dynamical system that produces cyclical state transitions using noisy input. SHN-based robot controllers enable sensory input to be integrated at the phase-space level of the controller, thus simplifying sensor-integrated, robot control methods. In this work, we investigate the mechanism that drives branching state trajectories in SHNs. We liken the branching state trajectories to decision-splits imposed into the system, which opens the door for more sophisticated controls-all driven by sensory input. This …

Soft Robotic Brittle Star Shows The Influence Of Mass Distribution On Underwater Walking, Zach J. Patterson

Faculty Scholarship

Most walking organisms tend to have relatively light limbs and heavy bodies in order to facilitate rapid limb motion. However, the limbs of brittle stars (Class Ophiuroidea) are primarily comprised of dense skeletal elements, with potentially much higher mass and density compared to the body disk. To date, little is understood about how the relatively unique distribution of mass in these animals influences their locomotion. In this work, we use a brittle star inspired soft robot and computational modeling to examine how the distribution of mass and density in brittle stars affects their movement. The soft robot is fully untethered, …

Behavior Of Rio Sao Francisco Piranhas In Response To Changes In Space And Density, Ronald G. Oldfield, Josie E. Thal, Kristen E. Lukas

Faculty Scholarship

Previous observations of Rio Sao Francisco piranhas (Pygocentrus piraya) at Cleveland Metroparks Zoo revealed frequent aggressive interactions, which were associated with the injury and death of some individuals. Fishes are known to increase aggressive behavior when available space is limited. We compared the behavior of the piranhas longitudinally across three different space/density conditions: (1) in a group held in a small aquarium before the death of one individual, (2) in the same group after the death of one individual, (3) and in one individual of the group after it was later moved into a larger, multispecies aquarium. In the smaller …

Dietary Effects On The Retina Of Hamsters, Nicole El-Darzi, Natalia Mast, Yong Li, Irina A. Pikuleva

Faculty Scholarship

The retina is a sensory tissue in the back of the eye, which captures visual information and relays it to the brain. The retinal pigment epithelium separates the neural retina from the choroidal (systemic) circulation and is thereby exposed to circulating lipoprotein particles. Herein, we used hamsters and conducted various retinal evaluations of animals fed either a normal diet or a Western-type diet (WTD). Prior to evaluations, hamsters were injected with indocyanine green (ICG), a fluorescent dye that binds to various proteins and lipids in the systemic circulation. The WTD increased plasma levels of total and HDL cholesterol 1.8- and …

Neuropeptide-Dependent Spike Time Precision And Plasticity In Circadian Output Neurons, Bryan Chong, Vipin Kumar, Dieu Linh Nguyen, Makenzie A. Hopkins, Faith S. Ferry, Lucia K. Spera, Elizabeth M. Paul, Anelise N. Hutson, Masashi Tabuchi

Faculty Scholarship

Circadian rhythms influence various physiological and behavioral processes such as sleep–wake cycles, hormone secretion, and metabolism. In Drosophila, an important set of circadian output neurons is called pars intercerebralis (PI) neurons, which receive input from specific clock neurons called DN1. These DN1 neurons can further be subdivided into functionally and anatomically distinctive anterior (DN1a) and posterior (DN1p) clusters. The neuropeptide diuretic hormones 31 (Dh31) and 44 (Dh44) are the insect neuropeptides known to activate PI neurons to control activity rhythms. However, the neurophysiological basis of how Dh31 and Dh44 affect circadian clock neural coding mechanisms underlying sleep in Drosophila is …

Flapping Dynamics And Wing Flexibility Enhance Odor Detection In Blue Bottle Flies, Naeem Haider, Zhipeng Lou, Chengyu Li

Faculty Scholarship

One of the most ancient and evolutionarily conserved behaviors in the animal kingdom involves utilizing wind-borne odor plumes to track essential elements such as food, mates, and predators. Insects, particularly flies, demonstrate a remarkable proficiency in this behavior, efficiently processing complex odor information encompassing concentrations, direction, and speed through their olfactory system, thereby facilitating effective odor-guided navigation. Recent years have witnessed substantial research explaining the impact of wing flexibility and kinematics on the aerodynamics and flow field physics governing the flight of insects. However, the relationship between the flow field and olfactory functions remains largely unexplored, presenting an attractive frontier …

Human Mesenchymal Stem Cell Therapy: Potential Advances For Reducing Cystic Fibrosis Infection And Organ Inflammation, Tracey L. Bonfield, Hillard M. Lazarus

Faculty Scholarship

Innovation in cystic fibrosis (CF) supportive care, including implementing new antimicrobial agents, improved physiotherapy, and highly effective modulators therapy, has advanced patient survival into the 4th and 5th decades of life. However, even with these remarkable improvements in therapy, CF patients continue to suffer from pulmonary infection and other visceral organ complications associated with long-term deficient cystic fibrosis transmembrane conductance regulator (CFTR) expression. Human mesenchymal stem cells (MSCs) have been utilized in tissue engineering based upon their capacity to provide structural components of mesenchymal tissues. An alternative role of MSCs, however is their versatile utilization as cell-based infusion powerhouses due …

Heterogeneity Of Layer 1 Interneurons In The Mouse Medial Prefrontal Cortex, Chen Shen, Wanpeng Cui, Wen Cheng Xiong, Lin Mei

Faculty Scholarship

Cortical Layer 1 (L1) acts as a critical relay for processing long-range inputs. GABAergic inhibitory interneurons (INs) in this layer (Layer 1 interneurons [L1INs]) function as inhibitory gates, regulating these inputs and modulating the activity of deeper cortical layers. However, their characteristics and circuits in the medial prefrontal cortex (mPFC) remain poorly understood. Using biocytin labeling, we identified three distinct morphological types of mPFC L1INs: neurogliaform cells (NGCs), elongated NGCs (eNGCs), and single-bouquet cell-like (SBC-like) cells. Whole-cell recordings revealed distinct firing patterns across these subtypes: NGCs and eNGCs predominantly exhibited late-spiking (LS) patterns, and SBC-like cells displayed a higher prevalence …

Pirfenidone Delivery By Blow-Molded Pcl Nanofiber Mat To Reduce Collagen Synthesis By Fibroblasts, Maximilian Zernic, Maryo Kohen, Faruk H. Orge, Amel Ahmed, Ozan Akkus

Faculty Scholarship

Elevated intraocular pressure (IOP) during glaucoma is sometimes mitigated by insertion of glaucoma drainage devices (GDD). Excessive fibrosis around GDD plates may confine drainage and requiring revision surgeries in some patients. Pirfenidone (PFD) is an FDA approved drug to treat lung fibrosis, and it may be effective in limiting capsule formation around the GDD. To enable this, we aimed to develop a polymeric GDD encasement sheath that can sustainably release PFD to reduce fibrous capsule formation. The PFD-doped sheath was manufactured by blow molding of (poly)caprolactone (PCL). We investigated the effects of PCL concentration, spray distance, and molecular weight on …

Regionalism And The Federal Reserve Banks, Kathryn Judge, Lev Menand

Faculty Scholarship

Regionalism is central to our country’s central banking system. Rather than rely on a single organization to set monetary policy and oversee banks, Congress created a multiplicity of bodies including twelve Federal Reserve Banks (FRBs), each designed to operate in a different part of the country. These FRBs are an early and undertheorized example of how the federal government uses regional bodies to formulate and administer federal policy. When they were first authorized in 1913, their regional character assuaged concerns about centralizing power over the economy. Today, the FRBs continue to play a number of important roles, helping to shape …

Human-Ai Collaboration In Writing: A Multidimensional Framework For Creative And Intellectual Authorship, James Hutson

Faculty Scholarship

The integration of AI technologies into the writing process has significantly altered traditional notions of authorship, creativity, and intellectual labor. Historically, writing was seen as a human-driven cognitive and creative exercise, but with the rise of generative AI tools such as ChatGPT and Claude, the line between human and AI contributions has become increasingly ambiguous. This paper addresses the limitations of the current sliding scale model, which views AI involvement as ranging from “none” to “complete”. In its place, we propose a new multidimensional framework that more accurately reflects the complexity of human-AI collaboration in writing. The model includes axes …

Performing Protest, Performing Memory: Speech Act Theory And January 6, Mary Lynne Gasaway Hill

Faculty Scholarship

In daily life, memory performs a staggering array of tasks. It offers reassurance, validation, legitimation, and approval. It transgresses boundaries and polices them. It confirms understandings and undermines them. It warms our hearts and chills our blood. In the realm of protest, as this article will show, memory works through intentional language use. In the context of activism, acts of memory are often performative: they aim not just to restate the status quo, but to change something about it. This chapter operationalises J.L. Austin’s Speech Act Theory (1994, SAT) as a lens through which to examine how the contentious discourse …

Redefining Cell Culture Using A 3d Flipwell Co-Culture System: A Mimetic For Gut Architecture And Dynamics In Vitro, Saori Furuta

Faculty Scholarship

Gut mucosae are composed of stratified layers of microbes, a selectively permeable mucus, an epithelial lining, and connective tissue homing immune cells. Studying cellular and chemical interactions between the gut mucosal components has been limited without a good model system. We have engineered a three-dimensional (3D) multi-cellular co-culture system we coined “3D Flipwell system” using cell culture inserts stacked against each other. This system allows an assessment of the impact of a gut mucosal environmental change on interactions between gut bacteria, epithelia, and immune cells. As such, this system can be utilized in examining the effects of exogenous stimuli, such …

This study reports on a bibliometric analysis that has identified the extent to which the topic has been explored in the international literature, by focusing on geographical scope, the emphasis on (micro)plastic litter and on policy measures. Additionally, as a complement to the assessment of the recent literature on marine plastic litter, this study reviews some case studies, identifying some trends on how to cope with this problem. The findings underscore the imperative for …

Thrombocytopenia In Sepsis, Alireza Setarehaseman, Robert W. Maitta

Faculty Scholarship

Platelets, traditionally known for their role in hemostasis, have emerged as key players in immune response and inflammation. Sepsis, a life-threatening condition characterized by systemic inflammation, often presents with thrombocytopenia, which at times, can be significant. Platelets contribute to the inflammatory response by interacting with leukocytes, endothelial cells, and the innate immune system. However, excessive platelet activation and consumption can lead to thrombocytopenia and exacerbate the severity of sepsis. Understanding the multifaceted roles of platelets in sepsis is crucial for developing effective therapeutic strategies. Targeting platelet-mediated inflammatory responses and promoting platelet production may offer potential avenues for improving outcomes in …

The Other Secret Deals: Uncovering The Power Of Non-Binding International Agreements, Guillermo J. Garcia Sanchez

Faculty Scholarship

In recent decades, the use of traditional international treaties has declined as states increasingly rely on deformalized agreements - non binding arrangements - such as interinstitutional agreements and memoranda of understanding. These agreements allow governments to bypass the complexities of formal treaty-making while addressing shared challenges. This Article, based on four years of research and previously undisclosed agreements, examines a twenty-year database of non-binding agreements between the United States and Mexico. Through this case study, the Article demonstrates how deformalized agreements drive much of the cross-border collaboration, offering a flexible mechanism for government agencies to shape state behavior, coordinate policies, …

Decriminalization Matters: Lgbtq Transnational Litigation Networks And Movement Lawyering In The Global South, Ayodeji Kamau Perrin

Faculty Scholarship

In the last decade, a distinct sociolegal phenomenon has been sweeping across the Global South—the judicial decriminalization of same-sex sexual conduct. On the other hand, progress on LGBTQ rights has occurred in parallel to transnational countermobilization and backlash against LGBTQ rights. Yet, neither the phenomenon of judicial decriminalization nor the countermobilization and backlash to decriminalization has attracted the attention that these phenomena deserve from doctrinal legal scholars, comparative and international law scholars, or legal mobilization scholars.

In this paper, I help to remedy this oversight by making three contributions to legal mobilization scholarship and to international law and relations scholarship. …

Tradeoffs In The Energetic Value Of Neuromodulation In A Closed-Loop Neuromechanical System, Zhuojun Yu, Peter J. Thomas, Hillel J. Chiel

Faculty Scholarship

Rhythmic motor behaviors controlled by neuromechanical systems, consisting of central neural circuitry, biomechanics, and sensory feedback, show efficiency in energy expenditure. The biomechanical elements (e.g., muscles) are modulated by peripheral neuromodulation which may improve their strength and speed properties. However, there are relatively few studies on neuromodulatory control of muscle function and metabolic mechanical efficiency in neuromechanical systems. To investigate the role of neuromodulation on the system's mechanical efficiency, we consider a neuromuscular model of motor patterns for feeding in the marine mollusk Aplysia californica. By incorporating muscle energetics and neuromodulatory effects into the model, we demonstrate tradeoffs in the …

Alpha Synuclein And Inflammaging, Geneviève L. Putnam, Robert W. Maitta

Faculty Scholarship

The α-synuclein protein is an established molecule in Lewy body pathology, especially Parkinson's disease (PD). While the pathological role of α-synuclein (α-syn) in PD has been well described, novel evidence may suggest that α-syn interacts with inflammasomes in response to aging. As age is an inevitable physiological state and is also considered the greatest risk factor for PD, this calls for investigation into how α-syn, aging, and PD could be linked. There is a growing amount of data regarding α-syn normal function in the body that includes involvement in cellular transport such as protein complexes assembly, vesicular trafficking, neurotransmitter release, …
