Molecular Fossils From Phytoplankton Reveal Secular Pco2 Trend Over The Phanerozoic, Caitlyn R. Witkowski, Johan W. H. Weijers, Brian S. Blais, Stefan Schouten, Jaap S. Sinninghe Damsté 2018 Utrecht University

Molecular Fossils From Phytoplankton Reveal Secular Pco2 Trend Over The Phanerozoic, Caitlyn R. Witkowski, Johan W. H. Weijers, Brian S. Blais, Stefan Schouten, Jaap S. Sinninghe Damsté

Science and Technology Faculty Journal Articles

Past changes in the atmospheric concentration of carbon dioxide (PCO2) have had a major impact on earth system dynamics; yet, reconstructing secular trends of past PCO2 remains a prevalent challenge in paleoclimate studies. The current long-term PCO2reconstructions rely largely on the compilation of many different proxies, often with discrepancies among proxies, particularly for periods older than 100 million years (Ma). Here, we reconstructed Phanerozoic PCO2 from a single proxy: the stable carbon isotopic fractionation associated with photosynthesis (Ɛp) that increases as PCO2 increases. This concept has been widely applied to alkenones, but here, we expand ...


Impacts Of Urbanization On Costs Of Production And Land Use In The Central Southern Seaboard: A Farm-Level Analysis, Richard F. Nehring, Kenneth Erickson, James M. Harris, Charlie Hallahan, Ani Katchova, Flavius Badau 2018 USDA, Economic Research Service

Impacts Of Urbanization On Costs Of Production And Land Use In The Central Southern Seaboard: A Farm-Level Analysis, Richard F. Nehring, Kenneth Erickson, James M. Harris, Charlie Hallahan, Ani Katchova, Flavius Badau

Journal of Applied Farm Economics

This study uses stochastic production frontier (SPF) and DEA frontier methods to estimate the impact of urban influence on the cost of production for traditional corn/soybeans farms in the Southern Seaboard (excepting Virginia and Alabama). We hypothesize that urban influence decreases the technical efficiency of these farms. Although states in this region are not entirely subject to urban influence, some parts of states in this region are highly urbanized. We find that farmers in urban-influenced locations are less technically efficient than farmers in rural locations in the region examined. During 2002-2014, stochastic production frontier and DEA frontier procedures indicate ...


Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David McFarlane, Chris Boyer, J. Travis Mulliniks 2018 California Polytechnic State University, San Luis Obispo

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF ...

The Gut Microbiota Of Cornu Aspersum, Parker Neal Smith, Sarah M. Boomer, Michael Baltzley 2018 Western Oregon University

The Gut Microbiota Of Cornu Aspersum, Parker Neal Smith, Sarah M. Boomer, Michael Baltzley

PURE Insights

The “Brown Garden Snail,” Cornu aspersum is a widely distributed land snail, whose consumption of soil to acquire calcium results in soil microbes colonizing their gut. While previous work has utilized culture-based approaches to analyze the gut microbiota of C. aspersum, no previous studies have used high throughput DNA sequencing, or examined the changes in the gut microbiota over time in response to antibiotics exposure. In this study, we use 16S amplicon sequencing and fecal plating to characterize the gut microbiota of C. aspersum, and to monitor changes in their microbiota over time after a short penicillin treatment. We found ...


Bacterial Abundance And Resistance In Ground Beef Varieties, Savannah Kumar, Sarah M. Boomer 2018 Western Oregon University

Bacterial Abundance And Resistance In Ground Beef Varieties, Savannah Kumar, Sarah M. Boomer

PURE Insights

Raw ground beef purchased at supermarkets across America have one thing in common: they harbor bacteria, some of which are drug resistant and can be detrimental to public health. To understand the impact of farming and processing practices on the quantity of bacteria and drug resistance, organic and regular beef were assessed using MacConkey media. Bacterial colonies were sorted according to lactose utilization, with positive colonies representing fecal E. coli. Lactose negative colonies were further characterized into one of two groups (fecal Hafnia-like or soil Pseudomonas) using a variety of metabolic tests (oxidase, sulfur, indole). Advanced metabolic testing showed that ...

Ecology, Evolution and Organismal Biology Publications

We employed phylogenomic methods to study molecular evolutionary processes and phylogeny in the geographically widely dispersed New World diploid cottons (Gossypium, subg. Houzingenia). Whole genome resequencing data (average of 33X genomic coverage) were generated to reassess the phylogenetic history of the subgenus and provide a temporal framework for its diversification. Phylogenetic analyses indicate that the subgenus likely originated following trans-oceanic dispersal from Africa about 6.6 mya, but that nearly all of the biodiversity evolved following rapid diversification in the mid-Pleistocene (0.5-2.0 mya), with multiple long-distance dispersals required to account for range expansion to Arizona, the Galapagos Islands ...

Expression Of Hepatic Cytochrome P450 Drug Metabolizing Enzymes In Diabetes And Diabetic Nephropathy, Cheng Jay Fang 2018 The University of Western Ontario

Expression Of Hepatic Cytochrome P450 Drug Metabolizing Enzymes In Diabetes And Diabetic Nephropathy, Cheng Jay Fang

Electronic Thesis and Dissertation Repository

The prevalence of diabetes worldwide is rapidly increasing. Polypharmacy, along with a high risk of adverse drug reactions, is common in diabetic patients. Cytochrome P450 (CYP) 3A and 2C drug metabolizing enzymes are reduced in chronic kidney disease (CKD), altering drug pharmacokinetics and contributing to adverse drug reactions. A large fraction of commonly prescribed drugs are metabolized by CYP3A and CYP2C. Approximately 40% of all CKD cases are attributed to diabetic nephropathy (DN) and early DN presents as mild kidney disease. This study aims to evaluate the impact of diabetes and DN on levels and activity of hepatic CYP3A and ...

Prenylation In The Moss Physcomitrella Patens, Noela Botaka, Susana Perez-Martinez, Liang Bao, Parul Singh, Mark Running

Posters-at-the-Capitol

Protein prenylation is a post-translational modification that involves the addition of lipid groups to the end of a target protein and is necessary for protein activity. Prenylation has important roles in the cell: targeting and localizing proteins to subcellular compartments and promoting protein-protein interactions. Recently, we have found Protein Prenyltransferase Alpha Subunit-like (PPAL), which shares structural similarities to known prenylation enzymes. However, the biochemical function of PPAL is still unknown. PPAL is present in a single copy in other plants examined to date but is present in two copies in moss. Knockouts in our lab of either PpPAL1 or PpPAL2 ...

A Crispr Platform For Rapid And Inducible Genome Editing In Human Non-Small Cell Lung Cancer Cells, Lloyd Bartley 2018 Murray State University

A Crispr Platform For Rapid And Inducible Genome Editing In Human Non-Small Cell Lung Cancer Cells, Lloyd Bartley

Posters-at-the-Capitol

Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancer, which is the leading cause of cancer death in the world. High mortality rate associated with NSCLC is partially attributed to the limited understanding of NSCLC as well as ineffective therapeutic treatments. The initiation and progression of NSCLC involves genetic changes leading to alterations in the control of tissue development and homeostatic maintenance. Better knowledge about these genetic abnormalities is imperative for developing new chemotherapeutic drugs for NSCLC. Recent research demonstrates that the expression of paraoxonase 2 (PON2), a lactonase/arylesterase with anti-oxidant properties, are markedly enhanced in ...


Detection Of Correlated Hidden Factors From Single Cell Transcriptomes Using Iteratively Adjusted-Sva (Ia-Sva)., Donghyung Lee, Anthony Cheng, Nathan Lawlor, Mohan Bolisetty, Duygu Ucar 2018 The Jackson Laboratory

Detection Of Correlated Hidden Factors From Single Cell Transcriptomes Using Iteratively Adjusted-Sva (Ia-Sva)., Donghyung Lee, Anthony Cheng, Nathan Lawlor, Mohan Bolisetty, Duygu Ucar

Faculty Research 2018

Single cell RNA-sequencing (scRNA-seq) precisely characterizes gene expression levels and dissects variation in expression associated with the state (technical or biological) and the type of the cell, which is averaged out in bulk measurements. Multiple and correlated sources contribute to gene expression variation in single cells, which makes their estimation difficult with the existing methods developed for batch correction (e.g., surrogate variable analysis (SVA)) that estimate orthogonal transformations of these sources. We developed iteratively adjusted surrogate variable analysis (IA-SVA) that can estimate hidden factors even when they are correlated with other sources of variation by identifying a set of ...

Novel Inactivation Of The Causative Fungus Of White Nose Syndrome With Methoxsalen And Ultraviolet A Light, Colin J. Hartman, Joseph Mester PhD, Alan Cohen MD 2018 Northern Kentucky University

Novel Inactivation Of The Causative Fungus Of White Nose Syndrome With Methoxsalen And Ultraviolet A Light, Colin J. Hartman, Joseph Mester Phd, Alan Cohen Md

Posters-at-the-Capitol

White Nose Syndrome (WNS) is a newly recognized disease responsible for the rapid mass destruction of the North American bat populations. This study addressed the novel inactivation of fungal spores from Pseudogymnoascus destructans, the causative agent of WNS, using ultraviolet A (UVA) light at 365nm and methoxsalen, a photosensitizer from a family of compounds known as furanocoumarins. Penicillium crustosum, an environmental fungus, was studied as a comparator.

Spore suspensions were soaked in specific concentrations of methoxsalen and subsequently exposed to UVA light. The plates were examined for both spore inactivation and resultant inhibition of colony growth. The results demonstrated that ...


Hitchhiker's Guide To Migration: Effects Of Experimental Parasitic Infection And Other Immune Challenges On Migratory Traits Of Sparrows, Tosha R. Kelly 2018 The University of Western Ontario

Hitchhiker's Guide To Migration: Effects Of Experimental Parasitic Infection And Other Immune Challenges On Migratory Traits Of Sparrows, Tosha R. Kelly

Electronic Thesis and Dissertation Repository

Seasonal migration exposes animals to a variety of habitats and parasites, and if infected migratory birds migrate successfully there is great potential for birds to transport infectious diseases long distances. Our current understanding of whether birds contribute to the spread of disease relies upon observational field studies that are limited in their ability to discern cause from effect. Using captive and field-based experiments for my doctoral research, I answered three research questions: (1) are nocturnal migratory restlessness (Zugunruhe) and body condition affected by mounting an acute phase immune response during migration; (2) what are the impacts of parasitic infection on ...
