Hormonal And Circuit Mechanisms Controlling Female Sexual Behavior, Sayaka Inoue

2020-Current year OA Pubs

Sexual behavior is crucial for reproduction in many animals. In many vertebrates, females exhibit sexual behavior only during a brief period surrounding ovulation. Over the decades, studies have identified the roles of ovarian sex hormones, which peak in levels around the time of ovulation, and the critical brain regions involved in the regulation of female sexual behavior. Modern technical innovations have enabled a deeper understanding of the neural circuit mechanisms controlling this behavior. In this review, I summarize our current knowledge and discuss the neural circuit mechanisms by which female sexual behavior occurs in association with the ovulatory phase of …

Infringement Episodes, Shani Shisha

Faculty Journal Articles and Book Chapters

For decades, copyright scholars have waged a spirited campaign against statutory damages. Our remedial system, critics say, is an incoherent mess. The core problem is that copyright holders can recover a separate award of statutory damages for every infringed work. As a result, damages can rapidly add up in any case involving multiple works. Because the number of statutory awards is tethered to the number of works, even trivial claims can lead to crippling damages. Commentators, policymakers, and judges have criticized this system as arbitrary and overbroad. And yet it endures. This Article argues that copyright’s per-work scheme has obscured, …

The Catholic Modernity Of Pope Benedict Xvi: Healthy Secularity And Christian Jurisprudence, Zachary R. Calo

Scholarly Works

This article examines the concept of healthy secularity in the thought of Pope Benedict XVI. In developing the idea of healthy secularity, Benedict builds upon longstanding themes in Catholic social thought while also provoking a deeper engagement with western modernity. Rather than placing Christianity and the secular in an oppositional framework, Benedict positions Christianity as the foundation of an authentic secular order. In so doing, he opens up new modes of critical engagement with western legal and political thought. Yet, while the concept offers a creative theological method for addressing contemporary issues, it depends for its realisation on vanishing cultural …

Ifn-𝜸 And Il-10 Immunosensor With Vertically Aligned Carbon Nanotube Interdigitated Electrodes Toward Pen-Side Cattle Paratuberculosis Monitoring, Shaowei Ding, Benjamin J. Brownlee, Kshama Parate, Cicero C. Pola, Bolin Chen, Jesse M. Hostetter, Douglas Jones, John Jackman, Brian D. Iverson, Jonathan C. Claussen

Faculty Publications

Highly sensitive vertically aligned carbon nanotube arrays (VANTAs) interdigitated electrode (IDE) arrays are developed for electrochemical biosensing of two cytokines (i.e., interleukin-10 (IL-10) and interferon-gamma (IFN-𝜸)) that are useful for early detection Johne’s disease (Bovine Paratuberculosis) in cattle. The high aspect ratio VANTA-IDEs (50–60 μm in height) are grown through a chemical vapor deposition process from an iron (Fe) catalyst that is lithographically patterned on a silicon wafer with equal finger width and inter-finger spacing of 25 μm. After functionalization with distinct antibodies the VANTA-IDEs are capable of selective detection of both IL-10 and IFN-𝜸 within an actual biological matrix …

Biophilic Design And Biophilic Cities: An Explainer, Kincaid Brown

Law Librarian Scholarship

The COVID-19 pandemic brought into focus that outdoor activities in natural settings have a positive impact on mental health, and individuals participating in outdoor activity report higher rates of emotional well-being than individuals who do not participate in such activity. Biophilic design is an architectural practice that aims to connect people to nature through design concepts with one of the benefits being psychological. Other benefits of biophilic design include improvements to environmental quality, physical health, support of animal species and habitats, and more resilient and energy-efficient cities.

Neurosteroids: Mechanistic Considerations And Clinical Prospects, Jamie L Maguire, Steven Mennerick

2020-Current year OA Pubs

Like other classes of treatments described in this issue's section, neuroactive steroids have been studied for decades but have risen as a new class of rapid-acting, durable antidepressants with a distinct mechanism of action from previous antidepressant treatments and from other compounds covered in this issue. Neuroactive steroids are natural derivatives of progesterone but are proving effective as exogenous treatments. The best understood mechanism is that of positive allosteric modulation of GABA

A Neural Mechanism For Conserved Value Computations Integrating Information And Rewards, Ethan S Bromberg-Martin, Yang-Yang Feng, Takaya Ogasawara, J Kael White, Kaining Zhang, Ilya E Monosov

2020-Current year OA Pubs

Behavioral and economic theory dictate that we decide between options based on their values. However, humans and animals eagerly seek information about uncertain future rewards, even when this does not provide any objective value. This implies that decisions are made by endowing information with subjective value and integrating it with the value of extrinsic rewards, but the mechanism is unknown. Here, we show that human and monkey value judgements obey strikingly conserved computational principles during multi-attribute decisions trading off information and extrinsic reward. We then identify a neural substrate in a highly conserved ancient structure, the lateral habenula (LHb). LHb …

Hyperbaric Oxygen Augments Susceptibility To C. Difficile Infection By Impairing Gut Microbiota Ability To Stimulate The Hif-1Α-Il-22 Axis In Ilc3, José L Fachi, Laís P Pral, Helder C Assis, Sarah Oliveira, Vinícius R Rodovalho, Jefferson A C Dos Santos, Mariane F Fernandes, Valquíria A Matheus, Renata Sesti-Costa, Paulo J Basso, Marina Flóro E Silva, Niels O S Câmara, Selma Giorgio, Marco Colonna, Marco A R Vinolo

2020-Current year OA Pubs

Hyperbaric oxygen (HBO) therapy is a well-established method for improving tissue oxygenation and is typically used for the treatment of various inflammatory conditions, including infectious diseases. However, its effect on the intestinal mucosa, a microenvironment known to be physiologically hypoxic, remains unclear. Here, we demonstrated that daily treatment with hyperbaric oxygen affects gut microbiome composition, worsening antibiotic-induced dysbiosis. Accordingly, HBO-treated mice were more susceptible to

The Role Of Pornography In The “Rough Sex” Defence In Canada, Lisa Gotell, Isabel Grant, Elizabeth Sheehy

All Faculty Publications

Drawing upon the authors’ earlier research studying the consent defence when it is used to suggest that the complainant agreed to “rough sex” involving violence, this paper develops an extended analysis of the complex role of pornography in these decisions. This paper focuses on a subset of “rough sex” cases, where pornography played a role in “scripting” the accused’s behaviour. Thematically, these cases included: those where the accused had a substantial history of consumption of violent pornography; cases in which the accused forced the complainant to view pornography as part of the assault; cases where the accused recorded the attack, …

Social Control And Homeless Encampments: Shifting The Role Of Shelters Through Judicial Review, Alexandra Flynn

All Faculty Publications

This paper examines the recent Canadian judicial decisions in relation to the eviction of encampment residents from public space to analyze what constitutes “reasonableness” in government decision-making in relation to short-term shelters. I argue that courts have called into question a key aspect of social control that relates to unhoused populations: the institutional belief that temporary shelters serve as a reasonable form of accommodation and an appropriate alternative to living in encampments. Recent legal decisions have challenged both this institutional belief and the methods used by officials to track which shelters are available. I conclude that the legal approach of …

Ddr2-Regulated Arginase Activity In Ovarian Cancer-Associated Fibroblasts Promotes Collagen Production And Tumor Progression, Favour A Akinjiyan, Zainab Ibitoye, Peinan Zhao, Leah P Shriver, Gary J Patti, Gregory D Longmore, Katherine C Fuh

2020-Current year OA Pubs

Ovarian cancer has poor survival outcomes particularly for advanced stage, metastatic disease. Metastasis is promoted by interactions of stromal cells, such as cancer-associated fibroblasts (CAFs) in the tumor microenvironment (TME), with tumor cells. CAFs play a key role in tumor progression by remodeling the TME and extracellular matrix (ECM) to result in a more permissive environment for tumor progression. It has been shown that fibroblasts, in particular myofibroblasts, utilize metabolism to support ECM remodeling. However, the intricate mechanisms by which CAFs support collagen production and tumor progression are poorly understood. In this study, we show that the fibrillar collagen receptor, …

The Neurochemistry Of Depression: The Good, The Bad And The Ugly, Kami Pearson, Kimberley Beier, Thornton Mardis, Bryan Munoz, Asma Zaidi

Faculty and Staff Publications

A large constellation of experimental evidence suggests that neuroinflammation is involved in the onset of depression and neurodegenerative disorders. Many studies have shown impairments in tryptophan metabolism, the major pathway for the synthesis of serotonin, the mood regulating neurotransmitter. This article reviews the various metabolites generated in the competing pathways of tryptophan metabolism including the kynurenine pathway. Increased synthesis of the neurotoxic compound quinolinic acid occurs at the expense of the synthesis of the neuroprotective metabolite kynurenic acid. This shift in equilibrium plays a critical role in the induction of oxidative stress, neuroinflammation, and neurotoxicity. Sufficient protein intake with adequate …

Control Of Acute Myeloid Leukemia And Generation Of Immune Memory In Vivo Using Amv564, A Bivalent Bispecific Cd33 X Cd3 T Cell Engager, Linda G. Eissenberg, Julie K. Ritchey, Michael P. Rettig, Dilan A. Patel, Kiran Vij, Feng Gao, Victoria Smith, Tae H Han, John F. Dipersio

2020-Current year OA Pubs

Off-the-shelf immunotherapeutics that suppress tumor growth and provide durable protection against relapse could enhance cancer treatment. We report preclinical studies on a CD33 x CD3 bivalent bispecific diabody, AMV564, that not only suppresses tumor growth, but also facilitates memory responses in a mouse model of acute myelogenous leukemia (AML). Mechanistically, a single 5-day treatment with AMV564 seems to reduce tumor burden by redirection of T cells, providing a time window for allogeneic or other T cells that innately recognize tumor antigens to become activated and proliferate. When the concentration of bispecific becomes negligible, the effector: target ratio has also shifted, …

Deals In The Heartland: Renewable Energy Projects, Local Resistance, And How Law Can Help, Christiana Ochoa, Kacey Cook, Hanna Weil

Articles by Maurer Faculty

This Article offers proposals for better engagements, relationships, and deals with local communities contemplating wind farms. Because the rapid expansion of wind energy to date has exhausted the first-mover rural communities, the promise of wind energy depends on reluctant rural communities that may require the legal, relational, and policy innovations proposed herein if they are to grant their consent to future wind farms and participate in the renewable energy transformation. The proposals herein are the result of empirical research exploring how occupants of rural spaces have reacted to wind developer’s strategies in their communities and how local communities have employed …

What Fischer V. United States Gets Wrong About Prosecutorial Discretion, Cindy J. Cho

Articles by Maurer Faculty

Conservative Supreme Court Justices have recently expressed heightened concerns about prosecutorial power in cases involving former President Donald Trump and the Capitol siege on January 6, 2021.  Making good on those worries, the conservative majority in Fischer v. United States, rested its decision in part on theoretical concerns about government overreach. The Department of Justice has pushed back on those concerns, but to this point, the debate has been mostly rhetorical and hypothetical.

This article attempts to fill that rhetorical void—and concretely answer the concerns animating Fischer—with evidence from actual cases.  A survey of ten January 6 cases …

Through Smoke And Mirrors: Excluding Malingering Expert Testimony Under The Daubert Standard, Chunlin Leonhard, Christoph Leonhard

Georgia Law Review

Because of science’s claim to objectivity, scientific testimony is persuasive and often outcome-determinative. Our adversarial system incentivizes litigants to proffer scientific evidence to support their positions. The task falls on trial judges as gatekeepers to distinguish valid scientific evidence from junk science. Drawing this line is difficult because scientific evidence covers a broad spectrum. The United States Supreme Court has set forth the standard of admissibility of scientific evidence in Daubert and its progeny (the Daubert Standard). Trial judges are supposed to admit scientific evidence only if reliable and relevant under the Daubert Standard. But three decades after Daubert, …

Exploring Long-Term Patterns: Black Bass Tournament Fishery And Population Trends In West Virginia's Navigable Rivers, Alex J. Benecke

Graduate Theses, Dissertations, and Problem Reports (ETD)

Black bass Micropterus spp. are popular sport fish in West Virginia’s navigable rivers. In recent years, anglers have expressed concerns about a potential decline in fishery quality. To investigate these claims, we evaluated whether fishery quality has declined compared to earlier periods and whether population trends correspond to angler catch rates. Specifically, we aimed to (1) examine changes in species catch over time and during key periods, such as tournament and spawning seasons; (2) describe the distribution of black bass species across pools and habitat types; and (3) assess the outcomes of previous stocking efforts. To address these objectives, we …

Assessing Virtual Reality’S Influence On Honesty In Reporting, Jeffrey Pickerd, Nathan Waddoups, David A. Wood, Xiaomei (Grazia) Xiong

Faculty Publications

Organizations, businesses, and society are exploring and adopting virtual reality (VR) and augmented reality (AR). VR is expected to boost the global economy by $1.5 trillion by 2030. In this study, we focus on the effect of VR on an important accounting variable—reporting honesty. We examine reporting honesty across two tasks, various measures, and various populations, that are commonly used in existing research. In our initial experiment, participants misreported more in a dice rolling task when performing it in a VR setting than in a non-VR setting. However, in a second and third experiment attempting to replicate and extend our …

Investigation Of Synergistic Effect Between Polystyrene And Polyethylene Under Conventional Thermal Heating And Microwave Heating, Thang Luong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Single-use plastics (Low Density Polyethylene, LDPE; Polystyrene, PS; Polypropylene, PP) are increasingly used in the modern world, with their usage growing every year. An effective method to manage the resulting waste is urgently needed, as landfilling and incineration have proven harmful to the environment in the long term. Mechanical recycling may not maintain the desirable characteristics of the single-use plastics through several cycles. Pyrolysis emerges as a promising approach to address plastic waste. Given that single-use plastic waste often comes in a mixture, combining plastic in the feedstock is a viable solution to effectively convert these polymers altogether to gain …

Iron Coated Sand: A Sustainable Substrate Amendment For Nutrient Management And Growth Of Floriculture Crops, Savannah Mead

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage and phosphorus pollution are two of the most pervasive forms of water contamination in Appalachia and globally. The horticultural industry is a contributor to nutrient pollution via leaching from greenhouses, necessitating the adoption of more sustainable practices for container production in controlled environments. In this thesis, an acid mine drainage-based iron-coated sand product was assessed on its effectiveness for phosphate adsorption when used as a sustainable substrate amendment for soilless container production of flowering ornamentals. The first study centered around the amount of iron-coated sand to use for production of petunias, pansies, and chrysanthemums. Iron-coated sand at …

Investigating The Role Of Spinal Motoneuron Organization In Human Motor Control, Rachel I. Taitano

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mechanisms of voluntary motor control are complex and require inputs via cortical centers, peripheral sensory systems, and spinal inputs such as central pattern generators. It is hypothesized that control is simplified via utilization of motor primitives, which may rely on structures within the spinal cord, however this remains unknown in both human and non-human primates. The goal of this dissertation is to characterize muscle activity in the upper extremity in relation to the corresponding anatomical organization of spinal motoneurons to provide insight into how primitives are both organized and activated to produce movement.

The first aim of this work was …

Evaluating The Efficacy Of The Archaeal Proteasome To Alleviate Protein-Misfolding Retinopathy, Celine Brooks

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nearly all neurodegenerative diseases (NDs) and some eye diseases are characterized by the presence of misfolded and aggregated proteins. The ubiquitin proteasome system (UPS) is responsible for degrading the majority of proteins including misfolded and aggregated proteins. However, in NDs the performance of the UPS is impaired, and this impairment partially comes from these protein aggregates inhibiting the proteasome. This inhibition leads to an accumulation of protein aggregates, more proteasomal inhibition, and fewer chaperones for newly synthesized proteins, triggering a collapse in proteostasis, which is thought to contribute to the pathogenesis of NDs. Consequently, stimulating proteasome function is being investigated …

The Role Of Uric Acid In Metabolic Abnormalities Of Obesity, Andrew P. Giromini

Graduate Theses, Dissertations, and Problem Reports (ETD)

Uric acid (UA) is the single most tightly associated metabolite for obesity and type 2 diabetes. While the field varies on whether UA is causative or correlative of the metabolic dysfunction allied to obesity, these studies use different diets and animal models to make these claims. It is the goal of this dissertation to compare different diets commonly used in this research to delve deeper into the data and determine which diets induce elevated circulating UA levels as well as which diets also induce metabolic dysfunction. Early chapters of this dissertation examine the comparison of high fructose consumption, both in …

Measures Of Feed Efficiency In Beef Cattle: Biological Basis And Effect On Response To Dietary Supplementation, Modoluwamu Idowu

Graduate Theses, Dissertations, and Problem Reports (ETD)

During the feedlot receiving period, newly weaned beef cattle face various stressors, including weaning, transportation, vaccination, and exposure to pathogens. Additionally, changes in diet and low dry matter intake contribute to nutrient deficiencies, heightening susceptibility to disease and performance declines. Therefore, we examined the effects of dietary supplementation with a multicomponent blend of prebiotics and probiotics on the health, immune status, metabolism, and performance of newly weaned beef steers during a 35-day receiving period. Our results showed that compared to the control group, the supplemental additive (SYNB) increased average daily gain (ADG), dry matter intake, and meal events during the …

Investigating The Effect Of Sign-Tracking On Attention And Perceptual Inference, Maria C. Potts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has shown that animals vary in the degree to which they attribute incentive salience to reward predictive cues. In Pavlovian conditioning, two behavioral phenotypes emerge: goal-tracking (GT), in which animals approach the site of the reward, and sign-tracking (ST), in which animals approach the conditioned stimulus and interact with it as if it has become a reward in its own right. ST has been associated with higher rates of impulsivity, drug reinstatement, and relapse, and is thought to confer addiction vulnerability. Though some studies have suggested that similar phenotypes exist in humans and are possibly related to addiction …

Aberrant Lipid Accumulation And Retinal Pigment Epithelium Dysfunction In Prcd-Deficient Mice, Sree Indrani Motipally

Graduate Theses, Dissertations, and Problem Reports (ETD)

Progressive Rod-Cone Degeneration (PRCD) is a peripheral membrane protein predominantly expressed in photoreceptor outer segment (OS) disc membranes with an unknown function. Several mutations in Prcd are implicated in Retinitis pigmentosa (RP) in humans. The most common “cysteine to tyrosine” (C2Y) mutation in Prcd leads to progressive retinal atrophy in multiple dog breeds and RP in humans. Canine models harboring the C2Y mutation in Prcd show disorganized OS structure with greatly attenuated photoreceptor OS renewal rates. Recent studies show defects in the photoreceptor nascent disc flattening in the absence of Prcd. However, it is unclear how OS discs eventually …

Synaptic Zinc Transporters Support Normal Synapse Structure And Function In Mouse Auditory Cortex, Abbey Manning

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many regions of the brain are highly enriched with free zinc inside glutamatergic vesicles at presynaptic terminals. At these synapses, zinc transporter 3 (ZnT3) moves zinc into vesicles where it is co-released with glutamate. Alterations in ZnT3 are implicated in multiple neurodevelopmental disorders, and ZnT3 knock-out (KO) mice – which lack synaptic zinc – show behavioral deficits associated with autism spectrum disorder and schizophrenia. Shank3 is a synaptic scaffolding protein that assists in tethering and organizing structural proteins and glutamatergic receptors in the postsynaptic density of excitatory synapses. The localization of Shank3 at excitatory synapses and the formation of stable …

An Inhibitory Recurrent Network In The Olfactory System, Farzaan Salman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neuromodulatory circuits are a necessary component of neural flexibility as they are able to act differentially depending on the receptors expressed by their downstream targets. Identifying the synaptic partners of modulatory neurons and determining the neurotransmitter and receptor content of these partners is necessary to identify the rules governing neuromodulatory circuits. In this study, I characterized the circuit of the contralaterally projecting, serotonin-immunoreactive deutocerebral neurons (CSDns), the sole synaptic source of the neuromodulator serotonin in the olfactory circuit of Drosophila melanogaster, by identifying the strongest synaptic partners of the CSDns, and the expression of genes encoding neurotransmitters and receptors of …
