Reframing Global Biodiversity Protection After Covid-19: Is International Environmental Law Up To The Task?, Maria Antonia Tigre, Natalia Urzola, Victoria Lichet

Sabin Center for Climate Change Law

In an increasingly interdependent world, the climate and biodiversity crises are, more than ever, inextricably tied to human health and the transmission of infectious diseases. The 2020 Covid-19 pandemic has irrevocably shown us that the exploitation of wild species and deforestation increases and modifies the interface between people and wildlife, leading to a spillover of diseases from wildlife to people. From a legal perspective, the gaps in international environmental law have contributed to the lack of an effective international biodiversity policy. In light of the challenges brought by the pandemic, there is now an opportunity to rethink our existing legal …

Predicting Online Sexual Victimization Among College Students: Sexting, Solicitations, And Other Risky Online Behaviors, Tianna Joy Knight

Masters Theses

With the high prevalence rates of internet usage and smartphone ownership, risky online behaviors have become more and more widespread. These behaviors include sexting, online sexual solicitations, and online sexual interactions. Research indicates that these risky behaviors are related to online sexual victimization (OSV). OSV has been associated with poorer mental health, loneliness, lower life satisfaction, and other negative outcomes. Another phenomenon linked to OSV and sexting is sexual exploitation, but no study has yet analyzed the predictive ability of beliefs and awareness about sexual exploitation and human trafficking on OSV. Optimism bias, or the tendency to think that one’s …

Ras-Mediated Tumor Stress Adaptation And The Targeting Opportunities It Presents, Alexandra Redding, A E Aplin, Elda Grabocka

Department of Cancer Biology Faculty Papers

Cellular stress is known to function in synergistic cooperation with oncogenic mutations during tumorigenesis to drive cancer progression. Oncogenic RAS is a strong inducer of a variety of pro-tumorigenic cellular stresses, and also enhances the ability of cells to tolerate these stresses through multiple mechanisms. Many of these oncogenic, RAS-driven, stress-adaptive mechanisms have also been implicated in tolerance and resistance to chemotherapy and to therapies that target the RAS pathway. Understanding how oncogenic RAS shapes cellular stress adaptation and how this functions in drug resistance is of vital importance for identifying new therapeutic targets and therapeutic combinations to treat RAS-driven …

Wenz, Fernanda Ferreira, Mireille Chahine, Joseph Dalton, Mario E. De Haro-Martí, Maristela Rovai, Noelia Silva-Del-Rio

Dairy Science and Food Science Faculty Publications: 2022 to Present

The aim of this study was to document California, Idaho, South Dakota, and Washington dairy producers' perspectives on the health and business implications of COVID-19 during the pandemic second wave. Dairy producers were reached by a 14-question anonymous mail survey during June and July of 2020. We obtained 226 responses (response rate: 9.3% CA, 8.6% ID, 31.4%, and 10.0% WA). Responses were grouped by state (CA: 48.7%, ID: 15.9%, SD: 21.7%, or WA: 13.7%) and dairy size [based on number of cows; small (<100): 14.1%, medium (100–499): 27.7%, medium-large (500–1,999): 33.2%, or large (≥2,000): 25.0%]. Survey responses were summarized, and multiple correspondence analysis was used to map responses and identify data clusters. At the time of the survey, some respondents suspected (3%) or had confirmed (9%) COVID-19 cases on their premises. Respondents were somewhat or very concerned about the health (75%) and business (92%) implications associated with COVID-19. Producers were concerned about the health of their families, employees, and employees' families; having to reduce production; workforce shortage; limited goods availability; and lack of services. Producers perceived that their employees were somewhat or very concerned (74%) with the pandemic. There was COVID-19 safety information or training provided (78%) or intended (4%) in English (22%), Spanish (23%), or both (55%). The focus of training was as follows: how to remain healthy at work (91%) and at home (60%), what to do if a worker gets sick (77%), and sick leave information (54%). Nevertheless, 18% of the respondents answered that training was not going to be provided. The following control measures implemented: providing hand sanitizer or disinfectant wipes (78%), instruction on frequent hand-washing (76%), social distancing (59%), prevention of employee gatherings (54%), providing and requiring the use of face masks (49%), and limiting on-farm visitors (44%). Multiple correspondence analysis showed that concern with health …

Corrigendum To "Unraveling The Mechanobiology Of Immune Cells" [Curr Opin Biotechnol 66 (2020) 236-245], Xuexiang Zhang, Tae-Hyung Kim, Timothy J. Thauland, Hongjun Li, Fatemeh Sadat Majedi, Chau Ly, Zhen Gu, Manish J. Butte, Amy C. Rowat, Song Li

Pathology Research and Scholarship

Immune cells can sense and respond to biophysical cues — from dynamic forces to spatial features — during their development, activation, differentiation and expansion. These biophysical signals regulate a variety of immune cell functions such as leukocyte extravasation, macrophage polarization, T cell selection and T cell activation. Recent studies have advanced our understanding on immune responses to biophysical cues and the underlying mechanisms of mechanotransduction, which provides rational basis for the design and development of immune-modulatory therapeutics. This review discusses the recent progress in mechanosensing and mechanotransduction of immune cells, particularly monocytes/macrophages and T lymphocytes, and features new biomaterial designs …

Prostacyclin Promotes Degenerative Pathology In A Model Of Alzheimer’S Disease, Tasha R. Womack, Craig T. Vollert, Odochi Ohia-Nwoko, Monika Schmitt, Saghi Montazari, Tina L. Beckett, David Mayerich, Michael Paul Murphy, Jason L. Eriksen

Sanders-Brown Center on Aging Faculty Publications

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that is the most common form of dementia in aged populations. A substantial amount of data demonstrates that chronic neuroinflammation can accelerate neurodegenerative pathologies. In AD, chronic neuroinflammation results in the upregulation of cyclooxygenase and increased production of prostaglandin H2, a precursor for many vasoactive prostanoids. While it is well-established that many prostaglandins can modulate the progression of neurodegenerative disorders, the role of prostacyclin (PGI2) in the brain is poorly understood. We have conducted studies to assess the effect of elevated prostacyclin biosynthesis in a mouse model of AD. Upregulated prostacyclin expression …

Estimated insect management costs and losses due to insects in soybean during the 2021 growing season were collected and compiled from 18 states to provide a record of insect pressure and management practices for the year. These annual estimates provide a historical record of pest pressure and insect management and have been compiled in some states since 2004. Participating states represented 47% of soybean acreage grown in the United States, with near 100% participation in southern states. Overall, the stink bug complex was the costliest insect pest in soybean followed by corn earworm. Total insect management costs were $18.53 per …

Inhibition Of Interferon-Gamma-Stimulated Melanoma Progression By Targeting Neuronal Nitric Oxide Synthase (Nnos), Shirley Tong, Maris A. Cinelli, Naglaa Salem El-Sayed, He Huang, Anika Patel, Richard B. Silverman, Sun Yang

Pharmacy Faculty Articles and Research

Interferon-gamma (IFN-γ) is shown to stimulate melanoma development and progression. However, the underlying mechanism has not been completely defined. Our study aimed to determine the role of neuronal nitric oxide synthase (nNOS)-mediated signaling in IFN-γ-stimulated melanoma progression and the anti-melanoma effects of novel nNOS inhibitors. Our study shows that IFN-γ markedly induced the expression levels of nNOS in melanoma cells associated with increased intracellular nitric oxide (NO) levels. Co-treatment with novel nNOS inhibitors effectively alleviated IFN-γ-activated STAT1/3. Further, reverse phase protein array (RPPA) analysis demonstrated that IFN-γ induced the expression of HIF1α, c-Myc, and programmed death-ligand 1 (PD-L1), in contrast …

Prediction Of Soil Water Content And Electrical Conductivity Using Random Forest Methods With Uav Multispectral And Ground-Coupled Geophysical Data, Yunyi Guan, Katherine R. Grote, Joel Schott, Kelsi Leverett

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The volumetric water content (VWC) of soil is a critical parameter in agriculture, as VWC strongly influences crop yield, provides nutrients to plants, and maintains the microbes that are needed for the biological health of the soil. Measuring VWC is difficult, as it is spatially and tempo-rally heterogeneous, and most agricultural producers use point measurements that cannot fully capture this parameter. Electrical conductivity (EC) is another soil parameter that is useful in agricul-ture, since it can be used to indicate soil salinity, soil texture, and plant nutrient availability. Soil EC is also very heterogeneous; measuring EC using conventional soil sampling …

Parallel Computing Framework And Gpu Performance Modeling, Wenjing Xu

Doctoral Dissertations

During the past decades, High-Performance Computing (HPC) has been widely used in various industries. In particular, the exponential growth of GPU (graphics processing unit) is a key technology that has helped promoting the development of artificial intelligence in real-world use cases. When we use GPU to accelerate parallel applications, its programmability, resource management, and scheduling are non-trivial jobs to obtain optimized performance. Therefore, how to effectively exploit GPU resources and improve program performance has been a hot research topic recently.

Benchmark does not always provide a good picture of the performance and details of the parallel applications. The various kinds …

Incorporating Microtopography In A Land Surface Model And Quantifying The Effect On The Carbon Cycle, J. D. Graham, D. M. Ricciuto, N. F. Glenn, P. J. Hanson

Geosciences Faculty Publications and Presentations

Northern peatlands are a terrestrial carbon store, with an annual sink of 0.1 Pg C yr⁻¹ and a total storage estimate of 547 Pg C. Northern peatlands are also major contributors of atmospheric methane. Most land surface models do not accurately represent peatland carbon emissions, partly because they do not represent the hydrologic cycle and/or microtopography adequately. Interactions between water table depth and microtopography in peatlands influence decomposition and modulate CO₂ and CH₄ fluxes. A modified version of the land surface component of the Energy Exascale Earth System Model, was recently created to represent the microtopography and …

Paths Of Coexistence: Spatially Predicting Acceptance Of Grizzly Bears Along Key Movement Corridors, Abigail H. Sage, Vicken Hillis, Rose A. Graves, Morey Burnham, Neil H. Carter

Human-Environment Systems Research Center Faculty Publications and Presentations

Landscape connectivity is important for conserving wildlife in spaces shared with humans. Yet, differences in human attitudes and behaviors within movement corridors can lead to spatial variation in the risks humans pose to wildlife. Mapping the spatial pattern of attitudes toward wildlife provides a useful tool for measuring this variation and promoting connectivity. We surveyed ranchers (n = 505) in the High Divide region in eastern Idaho and western Montana (United States) about their attitudes toward grizzly bears (Ursus arctos) – a species that can pose risks to livestock and human safety. We assessed spatial variation in …

Regulatory T Cells Control Effector T Cell Inflammation In Human Prediabetes, Rui Liu, Gabriella H. Pugh, Erin Tevonian, Katherine Thompson, Douglas A. Lauffenburger, Philip A. Kern, Barbara S. Nikolajczyk

Clinical and Translational Science Faculty Publications

A disparate array of plasma/serum markers provides evidence for chronic inflammation in human prediabetes, a condition that is most closely replicated by standard mouse models of obesity and metaflammation. These remain largely nonactionable and contrast with our rich understanding of inflammation in human type 2 diabetes. New data show that inflammatory profiles produced by CD4+ T cells define human prediabetes as a unique inflammatory state. Regulatory T cells (Treg) control mitochondrial function and cytokine production by CD4+ effector T cells (Teff) in prediabetes and type 2 diabetes by supporting T helper (Th)17 or Th1 cytokine production, respectively. These data suggest …

Variations In Risks From Smoking Between High-Income, Middle-Income, And Low-Income Countries: An Analysis Of Data From 179 000 Participants From 63 Countries, Thirunavukkarasu Sathish, Koon K. Teo, Philip Britz Mckibbin, Biban Gill, Shofiqul Islam, Guillaume Paré, Sumathy Rangarajan, Mylinh Duong, Fernando Lanas, Romaina Iqbal

Community Health Sciences

Background: Separate studies suggest that the risks from smoking might vary between high-income (HICs), middle-income (MICs), and low-income (LICs) countries, but this has not yet been systematically examined within a single study using standardised approaches. We examined the variations in risks from smoking across different country income groups and some of their potential reasons.
Methods: We analysed data from 134 909 participants from 21 countries followed up for a median of 11·3 years in the Prospective Urban Rural Epidemiology (PURE) cohort study; 9711 participants with myocardial infarction and 11 362 controls from 52 countries in the INTERHEART case-control study; and …

Glycerol-Driven Denitratation: Process Kinetics, Microbial Ecology, And Operational Controls, Matthew Baideme, Chenghua Long, Luke Plante, Jeffrey A. Starke, Michael A. Butkus, Katrik Chandran

Civil and Environmental Engineering Faculty Research and Publications

Denitratation, the selective reduction of nitrate to nitrite, is a novel process and when coupled with anaerobic ammonium oxidation (anammox) could achieve resource-efficient biological nitrogen removal of ammonium- and nitrate-laden waste streams. Using a fundamentally-based, first principles approach, this study optimized a stoichiometrically-limited, glycerol-driven denitratation process and characterized mechanisms supporting nitrite accumulation with results that aligned with expectations. At the optimal influent chemical oxygen demand to nitrate ratio of 3.0 : 1 identified, glycerol supported selective nitrate reduction to nitrite (nitrite accumulation ratio, NAR = 62%) and near-complete nitrate conversion (nitrate reduction ratio, NRR = 96%), indicating its viability in …

Childhood Depression: Identifying Depression In The Pediatric Population, Riley Alvaro

PCOM Capstone Projects

Internalizing disorders, such as major depressive disorder (MDD), are characterized by processes within the self since the primary symptoms tend to involve thoughts and feelings (APA, 2015). MDD is a mood disorder characterized by a persistently sad or irritable mood that affects one’s thinking and behavior and interferes with daily life (APA, 2015). In 2018, 3.2% of the pediatric population ages 3-17 in the United States were diagnosed with depression. (CDC, 2021). Depression and anxiety are comorbid disorders occurring concurrently; 73.8% of children diagnosed with MDD also have anxiety (CDC, 2021).

Internalizing disorders that are quiet and cause internal distress …

Spatiotemporal Patterns In The Biomass Of Drift Macroalgae In The Indian River Lagoon, Florida, United States, Lauren M. Hall, Lori J. Morris, Robert H. Chamberlain, M. Dennis Hanisak, Robert W. Virnstein, Richard Paperno, Bernhard Riegl, L. Rex Ellis, Ali Simpson, Charles A. Jacoby

Marine & Environmental Sciences Faculty Articles

Drift macroalgae plays key roles in the ecology of many coastal systems, including the Indian River Lagoon. In the lagoon, changes in the biomass of drift macroalgae may have interacted with an unprecedented bloom of phytoplankton in 2011. Patterns in the biomass of drift macroalgae were identified using new and original analyses of data from several sampling programs collected between 1997 and 2019. All available data show a relatively low biomass of drift macroalgae in 2010–2012, and surveys of fixed transects and seining as part of a fisheries independent monitoring program also recorded low biomass in 2016. Low light availability …

A Bayesian Phase I/Ii Biomarker-Based Design For Identifying Subgroup-Specific Optimal Dose For Immunotherapy, Beibei Guo, Yong Zang

Faculty Publications

Immunotherapy is an innovative treatment that enlists the patient's immune system to battle tumors. The optimal dose for treating patients with an immunotherapeutic agent may differ according to their biomarker status. In this article, we propose a biomarker-based phase I/II dose-finding design for identifying subgroup-specific optimal dose for immunotherapy (BSOI) that jointly models the immune response, toxicity, and efficacy outcomes. We propose parsimonious yet flexible models to borrow information across different types of outcomes and subgroups. We quantify the desirability of the dose using a utility function and adopt a two-stage dose-finding algorithm to find the optimal dose for each …

Singing Strategies Are Linked To Perch Use On Foraging Territories In Heart-Nosed Bats, Grace C. Smarsh, Ashley M. Long, Michael Smotherman

Faculty Publications

Acoustic communication allows animals to coordinate and optimize resource utilization in space. Cardioderma cor, the heart-nosed bat, is one of the few species of bats known to sing during nighttime foraging. Previous research found that heart-nosed bats react aggressively to song playback, supporting the territorial defense hypothesis of singing in this species. We further investigated the territorial defense hypothesis from an ecological standpoint, which predicts that singing should be associated with exclusive areas containing a resource, by tracking 14 individuals nightly during the dry seasons in Tanzania. We quantified the singing behavior of individuals at all perches used throughout the …

Strict Lyapunov Functions And Feedback Controls For Sir Models With Quarantine And Vaccination, Hiroshi Ito, Michael Malisoff, Frederic Mazenc

Faculty Publications

We provide a new global strict Lyapunov function construction for a susceptible, infected, and recovered (or SIR) disease dynamics that includes quarantine of infected individuals and mass vaccination. We use the Lyapunov function to design feedback controls to asymptotically stabilize a desired endemic equilibrium, and to prove input-to-state stability for the dynamics with a suitable restriction on the disturbances. Our simulations illustrate the potential of our feedback controls to reduce peak levels of infected individuals.
