Editorial: Early Career Scientists' Contributions To River Plastic Monitoring Across Scales, T Van Emmerik, D Gonzalez-Fernandez, F Mendrik, L Biermann, J Drummond, M Liedermann

School of Biological and Marine Sciences

Plastic pollution in aquatic ecosystems (rivers, lakes, estuaries, and oceans) is of growing global concern, because of its negative impact on environmental health, and human livelihood. Rivers are assumed to be one of the main transport pathways for land-based plastics from source to sea (Meijer et al., 2021). Yet, observations and understanding of riverine plastics are scarce in comparison to the marine environment. To optimize plastic pollution prevention, mitigation and reduction strategies, as well as reliable data on plastic abundance, transport, and types are crucial. However, a lack of consistent and long-term observations limits our ability to monitor plastics in …

Coal Geology & Exploration

Supercritical CO₂ can destroy the molecular structure of coal and increase the production of biomethane. To investigate the gas production potential under the in-situ conditions of coal reservoirs with the participation of supercritical CO₂, the original reservoir pressure, reservoir temperature, and gas composition of the target coal seam in a coalbed methane block in Xinjiang were used as the in-situ reservoir conditions. The self-designed anaerobic fermentation device for coal reservoirs was used to simulate the in-situ anaerobic fermentation process, and the biogas production, coal surface functional groups and microbial community structure under the in-situ conditions were analyzed. …

Plant-Soil Feedbacks Help Explain Plant Community Productivity, Andrew Kulmatiski, Jeanette Norton, Leslie E. Forero, Josephine Grenzer

Browse all Datasets

Plant community productivity tends to increase as species richness increases, but the mechanisms behind this biodiversity-productivity relationship are not fully understood. Plant-soil feedbacks (PSF) are a compelling potential mechanism of the biodiversity-productivity relationship because they can explain patterns of both underyielding and overyielding in diverse plant communities. To test the role of plant-soil feedbacks in the biodiversity-productivity relationship we measured all possible plant-soil feedbacks for sixteen species, and used the measured plant-soil feedbacks to predict plant community biomass production. We compared the predicted plant community biomass production to observed biomass production in a paired biodiversity-productivity experiment.

Differences Between Northern And Southern Female Coyotes, Alina Gabriela Monroy-Gamboa

Western North American Naturalist

The coyote (Canis latrans) has a wide distribution range, spanning boreal forests from the north of the continent to tropical environments in Central America, showing great adaptation and plasticity. Bergmann’s rule states that individuals inhabiting colder climates are larger than those in warmer climates. It is suggested that in carnivore species, litter size is influenced by allometric constraints such as maternal body size. The aim of this study is to analyze the relations using correlation between female coyote mass, latitude, and litter size. Using data compiled from the literature, I carried out statistical analyses to correlate female body …

Improving Water Quality Through Reducing Agricultural Nutrient Loss: Field Pennycress As A Cover Crop, Mujen Wang

Theses and Dissertations

Agricultural nutrient loss through water runoff from the Upper Mississippi (UM) River Basin is one of the major contributing sources to the Gulf of Mexico hypoxic dead zone. Cover cropping has been identified as one strategy for farmers to use to reduce nutrient loss from their fields. However, the upfront costs and slow economic return of implementing cover crops prevent farmers from widely adopting traditional cover crops.Field pennycress (Thlaspi arvense) is an emerging potential “cash cover crop” species that may provide the soil and environmental benefits of traditional cover crops and the economic incentive farmers need to widely implement cover …

Newborn Screening: Review Of Its Impact For Cystinosis, Katharina Hohenfellner, Ewa Elenberg, Gema Ariceta, Galina Nesterova, Neveen A Soliman, Rezan Topaloglu

Faculty, Staff and Students Publications

Newborn screening (NBS) programmes are considered to be one of the most successful secondary prevention measures in childhood to prevent or reduce morbidity and/or mortality via early disease identification and subsequent initiation of therapy. However, while many rare diseases can now be detected at an early stage using appropriate diagnostics, the introduction of a new target disease requires a detailed analysis of the entire screening process, including a robust scientific background, analytics, information technology, and logistics. In addition, ethics, financing, and the required medical measures need to be considered to allow the benefits of screening to be evaluated at a …

The Design, Construction, And Testing Of A Recombinant Dna Vaccine For Brucella Abortus And Brucella Melitensis, Stephanie Lynn Korle

LSU Doctoral Dissertations

Brucella spp. are a bacterium that cause brucellosis, a zoonotic disease, which is commonly seen in cattle, sheep, goats, swine, and canines. Brucellosis is a problem worldwide, although it is eradicated in some countries (Garin-Bastuji et al. 1998). The reason for designing recombinant DNA (rDNA) vaccines opposed to utilizing the live-attenuated vaccines on the market is that they cannot be given to pregnant animals without potentially causing abortion, while an rDNA vaccine should be safe for pregnant animals since it does not contain viable bacteria. Also, there are no serological tests that can accurately distinguish between an animal vaccinated …

Lactoferrin- And Dendrimer-Bearing Gold Nanocages For Stimulus-Free Dna Delivery To Prostate Cancer Cells, Jamal Almowalad, Partha Laskar, Sukrut Somani, Jitkasem Meewan, Rothwelle J. Tate, Christine Dufès

School of Medicine Publications

Background: The use of gene therapy to treat prostate cancer is hampered by the lack of effective nanocarriers that can selectively deliver therapeutic genes to cancer cells. To overcome this, we hypothesize that conjugating lactoferrin, a tumor-targeting ligand, and the diaminobutyric polypropylenimine dendrimer into gold nanocages, followed by complexation with a plasmid DNA, would enhance gene expression and anti-proliferation activity in prostate cancer cells without the use of external stimuli.

Methods: Novel gold nanocages bearing lactoferrin and conjugated to diaminobutyric polypropylenimine dendrimer (AuNCs-DABLf) were synthesized and characterized. Following complexation with a plasmid DNA, their gene expression, cellular uptake and antiproliferative …

On Efficacy And Effectiveness Of Vaccines: A Mathematical Approach Based On Conditional Probability With Applications To The Covid-19 Context, Flavius Guias

Spora: A Journal of Biomathematics

This paper presents a mathematically formalized approach which points out the relation between efficacy and effectiveness of vaccines. The first term denotes the relative degree of protection in clinical trials or under ideal conditions, while the latter is based on observed real-life data. We define the efficacy by a similar formula to the effectiveness, but the probabilities involved in the relative risk are conditional with respect to the exposure to the virus. If exposure and vaccination status are independent, the two quantities are equal. Otherwise, the observed value of the effectiveness is a biased one, as it could be seen …

Characterizing Edge Betweenness-Uniform Graphs, Jana Coroničová Hurajová, Tomas Madaras, Darren A. Narayan

Theory & Applications of Graphs

The betweenness centrality of an edge e is, summed over all u,v ∈ V(G), the ratio of the number of shortest u,v-paths in G containing e to the number of shortest u,v-paths in G. Graphs whose vertices all have the same edge betweenness centrality are called edge betweeness-uniform. It was recently shown by Madaras, Hurajová, Newman, Miranda, Fl´orez , and Narayan that of the over 11.7 million graphs with ten vertices or fewer, only four graphs are edge betweenness-uniform but not edge-transitive. In this paper we present new results involving properties of betweenness-uniform graphs.

Transcriptomic Analysis Of Liver Indicates Novel Vaccine To Porcine Reproductive And Respiratory Virus Promotes Homeostasis In T-Cell And Inflammatory Immune Responses Compared To A Commercial Vaccine In Pigs, Damarius S. Fleming, Laura C. Miller, Jiuyi Li, Albert Van Geelen, Yongming Sang

Agricultural and Environmental Sciences Faculty Research

One of the largest impediments for commercial swine production is the presence of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), a devastating RNA viral infection that is responsible for over $1 billion in loss in the U.S. annually. The challenge with combating PRRSV is a combination of the effect of an extraordinary rate of mutation, the ability to infect macrophages, and subversion of host immune response through a series of actions leading to both immunomodulation and immune evasion. Currently there are a handful of commercial vaccines on the market that have been shown to be effective against homologous infections, but …

Comparison Of Recent Survey Techniques For Estimating Benthic Cover On Caribbean Mesophotic Reefs, Joseph R. Pawlik, Roy A. Armstrong, Stephanie Farrington, John Reed, Sara Rivero-Calle, Hanumant Singh, Brian K. Walker, Jason White

Marine & Environmental Sciences Faculty Articles

Highly divergent estimates of benthic cover of sponges have been reported for Caribbean mesophotic reefs (90-100 m) based on quadrat point-intercept data collection using 2 methods: visual surveys conducted in situ by technical divers, and analyses of photographs taken by unmanned underwater vehicles (UUVs). The second method has been criticized for potential errors from image distortion caused by variable camera angle relative to the substratum, but without a broader comparison of both methods. We find that studies that have used the UUV-based method are advantageous for a number of reasons, most importantly: (1) access to the full mesophotic zone, (2) …
