Early Records Suggest A Broader Historic Range Of The Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens), D. Blake Sasse

Western North American Naturalist

The endangered Ozark big-eared bat (Corynorhinus townsendii ingens) is currently found in northcentral and northwestern Arkansas and northeastern Oklahoma. Although historically known to be present in 2 counties on the southwestern border of Missouri, this species has not been observed in Missouri since 1971. A female Ozark big-eared bat specimen in the museum collection of Harvard University was reportedly collected in Arkansas, possibly in 1858. An investigation of the documentation associated with this and other specimens collected by the same individual suggests that this Ozark big-eared bat may have been collected on the Osage River in west-central Missouri …

Genetic Insights Into The Introduction History Of Black Rats Into The Eastern Indian Ocean, Vicki A A. Thomson, Andrew S. Wiewel, Russell Palmer, Neil Hamilton, Dave Algar, Caitlyn Pink, Harriet Mills, Ken P. Aplin, Geoffrey Clark, Atholl Anderson, Michael B. Herrera, Steven Myers, Terry Bertozzi, Philip J. Piper, Hitoshi Suzuki, Steve Donnellan

Research outputs 2022 to 2026

Islands can be powerful demonstrations of how destructive invasive species can be on endemic faunas and insular ecologies. Oceanic islands in the eastern Indian Ocean have suffered dramatically from the impact of one of the world’s most destructive invasive species, the black rat, causing the loss of endemic terrestrial mammals and ongoing threats to ground-nesting birds. We use molecular genetic methods on both ancient and modern samples to establish the origins and minimum invasion frequencies of black rats on Christmas Island and the Cocos-Keeling Islands. We find that each island group had multiple incursions of black rats from diverse geographic …

Reactive Oxygen Species Reprogram Macrophages To Suppress Antitumor Immune Response Through The Exosomal Mir-155-5p/Pd-L1 Pathway, Xiang Li, Shaomin Wang, Wei Mu, Jennifer Barry, Anna Han, Richard L Carpenter, Bing-Hua Jiang, Stephen C Peiper, M G Mahoney, A E Aplin, Hong Ren, Jun He

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background: Cancer cells have an imbalance in oxidation-reduction (redox) homeostasis. Understanding the precise mechanisms and the impact of the altered redox microenvironment on the immunologic reaction to tumors is limited.

Methods: We isolated exosomes from ovarian cancer cells through ultracentrifuge and characterized by Western-blots and Nanoparticle Tracking Analysis. 2D, 3D-coculture tumor model, and 3D live cell imaging were used to study the interactions between tumor cells, macrophages and CD3 T cells in vitro. The role of exosomal miR-155-5p in tumor growth was evaluated in xenograft nude mice models and immune-competent mice models. Flow cytometry and flow sorting were used to …

Organoid Models For Infectious Disease, Sarah E Blutt, Mary K Estes

Faculty, Staff and Students Publications

Infectious diseases affect individual health and have widespread societal impacts. New ex vivo models are critical to understand pathogenesis, host response, and features necessary to develop preventive and therapeutic treatments. Pluripotent and tissue stem cell-derived organoids provide new tools for the study of human infections. Organoid models recapitulate many characteristics of in vivo disease and are providing new insights into human respiratory, gastrointestinal, and neuronal host-microbe interactions. Increasing culture complexity by adding the stroma, interorgan communication, and the microbiome will improve the use of organoids as models for infection. Organoid cultures provide a platform with the capability to improve human …

Enteroviruses And Type 1 Diabetes: Multiple Mechanisms And Factors?, Richard E Lloyd, Manasi Tamhankar, Åke Lernmark

Faculty, Staff and Students Publications

Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by insulin deficiency and resultant hyperglycemia. Complex interactions of genetic and environmental factors trigger the onset of autoimmune mechanisms responsible for development of autoimmunity to β cell antigens and subsequent development of T1D. A potential role of virus infections has long been hypothesized, and growing evidence continues to implicate enteroviruses as the most probable triggering viruses. Recent studies have strengthened the association between enteroviruses and development of autoimmunity in T1D patients, potentially through persistent infections. Enterovirus infections may contribute to different stages of disease development. We review data from both …

More Thinking About Thinking With Images: A Response To Ivan Gaskell, Deborah Knight And Sonia Sedivy, John M. Carvalho

Contemporary Aesthetics (Journal Archive)

I want to start by thanking my critics for reading my book and coming to so many insightful comments and challenging observations about it. I especially want to thank Deborah Knight for suggesting a panel to discuss the book and for doing so much to realize it. There is so much to say about the intelligent and generous commentary offered by Ivan Gaskell, Deborah Knight, and Sonia Sedivy. Put briefly, in the short space below, I say my book thinks mostly about how and that artworks mean rather than what they mean, as Gaskell recommends. Knight’s remarks prompt me to …

Rangeland Degradation In Mongolia – Using State And Transition Models To Help Understand Rangeland Dynamics, S. Sainnemekh, B. Densambuu, B. Bestelmeyer, I. C. Barrio, A. L. Aradóttir

IGC Proceedings (1977-2023)

Rangeland degradation and soil erosion pose constant challenges to the management of natural resources in Mongolia. Large increases in livestock numbers since the early 1990s, together with increasing temperatures and higher frequency of extreme weather events have led to widespread degradation of rangeland resources, to the extent that today, nearly 57% of rangelands in Mongolia are considered degraded to some degree. New ways of understanding the dynamics of rangeland ecosystems and guidelines to conserve healthy and productive rangelands are urgently needed. The application of State and Transition Models (STMs) in ecosystem management has shown promise to understand the mechanistic processes …

IGC Proceedings (1977-2023)

This trial aims to evaluate floristic composition of most abundant species in three soil typical of Pampa biome on Brazil. The survey was held at Maronna Fundation located on southern Alegrete municipality, on Rio Grande do Sul, Brazil’s state. Regional climate belongs to Koeppen’s Cfa class. Soil types were shallow basalt (Psamments e Orthents), deep basalt (Vertisols) and sandy soil (Acrisols or Ultisols). Floristic composition were evaluated by visual ranking of aerial biomass of the major species (transformed to kg of dry matter per hectare), calibrated by cuts at ground level, according to field procedures of BOTANAL method. Grasses were …

Interindividual Differences And Their Consistency In Grazing Cattle Behavior Across Seasons, H. Anzai, M. Shitajikkoku, K. Hani, N. Yamada, M. Hirata

IGC Proceedings (1977-2023)

Interindividual differences and their consistency in behavior were investigated for cattle (Bos taurus) grazing a bahiagrass (Paspalum notatum) and centipedegrass (Eremochloa ophiuroides) dominated pasture as a herd of about 30 breeding cows with their calves. Behavior of the cows was monitored directly by observers and also using GPS and accelerometer data loggers attached to focal cows for a period of 1–5 days every month during the grazing seasons (from May to October) in 2018 and 2019. The data were converted into behavioral variables (e.g. time spent grazing, ruminating and resting, time spent in particular …

Biodiversity Assessment And Conservation Of Threatened Plant Species Belonging To The Unique Steppe With Trees In Tunisian Drylands, Jamila Msadek, Mohamed Tarhouni

IGC Proceedings (1977-2023)

Biodiversity conservation from heavy grazing impacts, through the creation of national parks, is usually considered to sustain higher ecosystem resilience and to protect the natural plant cover as well as the threatened species. The study was carried out in Bou Hedma national park, a biosphere reserve containing the unique Acacia tortilis (Forssk.) Hayne subsp. raddiana (Savi) Brenan steppe with trees in Tunisia. Several functional traits of seven (7) rare and threatened plant species are used to highlight their adaptive strategies in order to understand the evolution of plant communities and the overall ecosystems functioning inside the park. Such results may …

Vegetation Response To Grazing Pressure In The Puna Flat, Nw Argentina, M. Quiroga Mendiola, A. Tálamo

IGC Proceedings (1977-2023)

Puna grasslands are located at a high‐altitude flat plateau in the Northwest of Argentina. It is an arid territory (100 to 300 mm rainfall/year) at 3,000 to 4,000 m a.s.l. The vegetation is scarce, where Andean pastoralist communities produce meat and wool, specialized in llama (Lama glama) and sheep‐breeding, although they do breed multi‐species herds that may also include goats and cattle. There are erosion processes in the Puna, where shepherds and their animals could be synergetic factors with natural very hard climatic conditions. In this work we assess the effect of ovine and lama grazing on the …

Grass Species Density And Biomass Of South African Communal Property Association Farms Differing In Soil Properties, K. E. Ravhuhali, B. Moyo

IGC Proceedings (1977-2023)

Attempts to monitor and mitigate rangeland deterioration in Communal Property Associations projects require some understanding of the knowledge of species composition and distribution. The study was conducted to compare the herbaceous in three selected CPAs projects (Mashung Matlala - Sandy loam, Mawela - clay loam, and Bela-Bela - clay) in South Africa. Mawela and Mashung Matlala CPAs were overgrazed. For species density, basal strike, and biomass, three transects (500m), which served as replicates, were established at two camps of each of the selected CPAs. Variation in herbaceous vegetation parameters was explored through SAS software. Clay soil type had better (P …

Polysaccharides, polypeptides, and nucleic acids can be produced into hydrogels, each for unique purposes depending on their qualities. Examples of polypeptide hydrogels include collagen, gelatin, and elastin, and polysaccharide hydrogels include alginate, cellulose, and glycosaminoglycan. Many different theories have been formulated to research hydrogels, which include Flory-Rehner theory, Rubber Elasticity Theory, and the calculation of porosity and pore size. All these theories take into consideration enthalpy, entropy, and other thermodynamic variables so that …

Does Breastfeeding Account For The Association Between Maternal Sensitivity And Infant Cognitive Development In A Large, Nationally Representative Cohort?, P. Nina Banerjee, Karen E. Mcfadden, Jacqueline D. Shannon, Leslie L. Davidson

Publications and Research

Background: Previous research has established that exposure to high maternal sensitivity is positively associated with advances in infant cognitive development. However, there are many fixed and modifiable factors that influence this association. This study investigates whether the association between maternal sensitivity and infant cognitive development in the first year of life is accounted for by other factors, such as breastfeeding, maternal depressive symptoms, maternal alcohol use, infant birth weight or demographic covariates.

Methods: Using data from the Early Childhood Longitudinal Study-Birth (ECLS-B) Cohort, a nationally representative sample of U.S. born children, multi-variable regression analyses was used to examine whether breastfeeding, …

Analysis Of Step Therapy Reform On Floridians With Autoimmune Conditions, John M. Kirkley Iii, Eren Tatari

Florida Public Health Review

Background: Step therapy is a cost-saving measure employed by insurance companies to reduce rising drug costs; however, studies have indicated this policy has neutral or – in some cases – negative effects on patients. Specifically for indivdiuals with autoimmune diseases, the delay of proper treatment, increased risk of negative, irreversible side effects, and an underdeveloped preferred drug lists harm autoimmune patients because of the disconnect between the heterogeneity of autoimmune disease and the one-size-fits-all approach of step therapy. Objective: To determine the most effective policy for dealing with the harms of step therapy as they currently affect Floridians. Methods: Five …

Temperature And Predator Effects On Green Crabs (Carcinus Maenas) And Their Distribution In South Slough National Estuarine Research Reserve, Elissa Connolly-Randazzo

Dissertations and Theses

The invasive green crab (Carcinus maenas) has increased in abundance and distribution among Oregon's estuaries. Its global success in establishing in new environments and tolerance for abiotic stressors, such as temperature, raises concern for C. maenas to negatively influence native crab species, especially given global climate change. To improve in predicting invasion impacts, this work analyzed the results from a controlled tank experiment at Portland State University and the field data on a population of C. maenas in South Slough National Estuarine Research Reserve (SSNERR). The aquarium experiment documented predation pressure on C. maenas across a range of …

Therapeutic Treatment With The Anti-Inflammatory Drug Candidate Mw151 May Partially Reduce Memory Impairment And Normalizes Hippocampal Metabolic Markers In A Mouse Model Of Comorbid Amyloid And Vascular Pathology, David J. Braun, David K. Powell, Christopher J. Mclouth, Saktimayee M. Roy, D. Martin Watterson, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

Alzheimer’s disease (AD) is the leading cause of dementia in the elderly, but therapeutic options are lacking. Despite long being able to effectively treat the ill-effects of pathology present in various rodent models of AD, translation of these strategies to the clinic has so far been disappointing. One potential contributor to this situation is the fact that the vast majority of AD patients have other dementia-contributing comorbid pathologies, the most common of which are vascular in nature. This situation is modeled relatively infrequently in basic AD research, and almost never in preclinical studies. As part of our efforts to develop …

Ice Recrystallization Inhibition Is Insufficient To Explain Cryopreservation Abilities Of Antifreeze Proteins, Yuling Sun, Daria Maltseva, Jie Liu, Theordore Hooker Ii, Volker Mailänder, Hans Ramløv, Arthur Devries, Mischa Bonn, Konrad Meister

Faculty, Staff, and Students

Antifreeze proteins (AFPs) and glycoproteins (AFGPs) are exemplary at modifying ice crystal growth and at inhibiting ice recrystallization (IRI) in frozen solutions. These properties make them highly attractive for cold storage and cryopreservation applications of biological tissue, food, and other water-based materials. The specific requirements for optimal cryostorage remain unknown, but high IRI activity has been proposed to be crucial. Here, we show that high IRI activity alone is insufficient to explain the beneficial effects of AF(G)Ps on human red blood cell (hRBC) survival. We show that AF(G)Ps with different IRI activities cause similar cell recoveries of hRBCs and that …

Blood Count Recovery Following Induction Therapy For Acute Myeloid Leukemia In Children Does Not Predict Survival, Lauren Pommert, Todd M. Cooper, Robert B. Gerbing, Lisa Brodersen, Michael Loken, Alan S. Gamis, Richard Aplenc, Todd A. Alonzo, Edwards Anders Kolb

Manuscripts, Articles, Book Chapters and Other Papers

International Working Group (IWG) and European LeukemiaNet (ELN) response definitions are utilized to evaluate the efficacy of new agents for childhood acute myeloid leukemia (AML) for regulatory purposes. However, these criteria are not consistent with definitions used in pediatric AML trials or with standard pediatric practice to proceed with subsequent therapy cycles prior to IWG/ELN-defined count recovery. We retrospectively analyzed data from the two most recent Phase 3 pediatric AML clinical trials conducted by the Children’s Oncology Group (COG) to assess the incidence, timing, and prognostic significance of count recovery following induction chemotherapy. Of the patients with fewer than 5% …

School of Graduate Studies Faculty Publications

Muscle builders frequently consume protein supplements, but little is known about their effect on the gut microbiota. This study compared the gut microbiome and metabolome of selfidentified muscle builders who did or did not report consuming a protein supplement. Twenty-two participants (14 males and 8 females) consumed a protein supplement (PS), and seventeen participants (12 males and 5 females) did not (No PS). Participants provided a fecal sample and completed a 24-h food recall (ASA24). The PS group consumed significantly more protein (118 ± 12 g No PS vs. 169 ± 18 g PS, p = 0.02). Fecal metabolome and …

Assessment Of Bacterial Inoculant Delivery Methods For Cereal Crops, Yen Ning Chai, Stephanie Futrell, Daniel P. Schachtman

Department of Agronomy and Horticulture: Faculty Publications

Despite growing evidence that plant growth-promoting bacteria can be used to improve crop vigor, a comparison of the different methods of delivery to determine which is optimal has not been published. An optimal inoculation method ensures that the inoculant colonizes the host plant so that its potential for plant growth-promotion is fully evaluated. The objective of this study was to compare the efficacy of three seed coating methods, seedling priming, and soil drench for delivering three bacterial inoculants to the sorghum rhizosphere and root endosphere. The methods were compared across multiple time points under axenic conditions and colonization efficiency was …
