Fat In Flames: Influence Of Cytokines And Pattern Recognition Receptors On Adipocyte Lipolysis, Ryan W. Grant, Jacqueline M. Stephens Jan 2015

Fat In Flames: Influence Of Cytokines And Pattern Recognition Receptors On Adipocyte Lipolysis, Ryan W. Grant, Jacqueline M. Stephens

Faculty Publications

© 2015 the American Physiological Society. Adipose tissue has the largest capacity to store energy in the body and provides energy through the release of free fatty acids during times of energy need. Different types of immune cells are recruited to adipose tissue under various physiological conditions, indicating that these cells contribute to the regulation of adipose tissue. One major pathway influenced by a number of immune cells is the release of free fatty acids through lipolysis during both physiological (e.g., cold stress) and pathophysiological processes (e.g., obesity, type 2 diabetes). Adipose tissue expansion during obesity leads to immune cell …

Seasonal Changes In Soil Organic Matter After A Decade Of Nutrient Addition In A Lowland Tropical Forest, Benjamin L. Turner, Joseph B. Yavitt, Kyle E. Harms, Milton N. Garcia, S. Joseph Wright Jan 2015

Seasonal Changes In Soil Organic Matter After A Decade Of Nutrient Addition In A Lowland Tropical Forest, Benjamin L. Turner, Joseph B. Yavitt, Kyle E. Harms, Milton N. Garcia, S. Joseph Wright

Faculty Publications

© 2015, US Government. Soil organic matter is an important pool of carbon and nutrients in tropical forests. The majority of this pool is assumed to be relatively stable and to turn over slowly over decades to centuries, although changes in nutrient status can influence soil organic matter on shorter timescales. We measured carbon, nitrogen, and phosphorus concentrations in soil organic matter and leaf litter over an annual cycle in a long-term nutrient addition experiment in lowland tropical rain forest in the Republic of Panama. Total soil carbon was not affected by a decade of factorial combinations of nitrogen, phosphorus, …

Fuels And Fires Influence Vegetation Via Above- And Belowground Pathways In A High-Diversity Plant Community, Paul R. Gagnon, Heather A. Passmore, Matthew Slocum, Jonathan A. Myers, Kyle E. Harms, William J. Platt, C. E.Timothy Paine Jan 2015

Fuels And Fires Influence Vegetation Via Above- And Belowground Pathways In A High-Diversity Plant Community, Paul R. Gagnon, Heather A. Passmore, Matthew Slocum, Jonathan A. Myers, Kyle E. Harms, William J. Platt, C. E.Timothy Paine

Faculty Publications

© 2015 British Ecological Society. Fire strongly influences plant populations and communities around the world, making it an important agent of plant evolution. Fire influences vegetation through multiple pathways, both above- and belowground. Few studies have yet attempted to tie these pathways together in a mechanistic way through soil heating even though the importance of soil heating for plants in fire-prone ecosystems is increasingly recognized. Here we combine an experimental approach with structural equation modelling (SEM) to simultaneously examine multiple pathways through which fire might influence herbaceous vegetation. In a high-diversity longleaf pine groundcover community in Louisiana, USA, we manipulated …

Are Receptor Concentrations Correlated Across Tissues Within Individuals? A Case Study Examining Glucocorticoid And Mineralocorticoid Receptor Binding, Christine R. Lattin, Daniel E. Keniston, J. Michael Reed, L. Michael Romero Jan 2015

Are Receptor Concentrations Correlated Across Tissues Within Individuals? A Case Study Examining Glucocorticoid And Mineralocorticoid Receptor Binding, Christine R. Lattin, Daniel E. Keniston, J. Michael Reed, L. Michael Romero

Faculty Publications

Copyright © 2015 by the Endocrine Society. Hormone receptors are a necessary (although not sufficient) part of the process through which hormones like corticosterone create physiological responses. However, it is currently unknown to what extent receptor concentrations across different target tissues may be correlated within individual animals. In this study, we examined this question using a large dataset of radioligand binding data for glucocorticoid receptors (GRs) and mineralocorticoid receptors (MRs) in 13 different tissues in the house sparrow (Passer domesticus) (n = 72). Our data revealed that individual house sparrows tended to exhibit higher or lower receptor binding across all …

Centimeter-Long Electron Transport In Marine Sediments Via Conductive Minerals, Nikhil S. Malvankar, Gary M. King, Derek R. Lovley Jan 2015

Centimeter-Long Electron Transport In Marine Sediments Via Conductive Minerals, Nikhil S. Malvankar, Gary M. King, Derek R. Lovley

Faculty Publications

© 2015 International Society for Microbial Ecology All rights reserved. Centimeter-long electron conduction through marine sediments, in which electrons derived from sulfide in anoxic sediments are transported to oxygen in surficial sediments, may have an important influence on sediment geochemistry. Filamentous bacteria have been proposed to mediate the electron transport, but the filament conductivity could not be verified and other mechanisms are possible. Surprisingly, previous investigations have never actually measured the sediment conductivity or its basic physical properties. Here we report direct measurements that demonstrate centimeter-long electron flow through marine sediments, with conductivities sufficient to account for previously estimated electron …

Physiological Profiles As Indicators Of Response To Hurricane Disturbance For Three Coastal Wetland Species, Alexandria Lynn Pivovaroff, Cheryl Swift, Loretta L. Battaglia, Brittany Kunz, William J. Platt, Carrie L. Yoder Jan 2015

Physiological Profiles As Indicators Of Response To Hurricane Disturbance For Three Coastal Wetland Species, Alexandria Lynn Pivovaroff, Cheryl Swift, Loretta L. Battaglia, Brittany Kunz, William J. Platt, Carrie L. Yoder

Faculty Publications

© Coastal Education & Research Foundation 2015. Hurricanes alter light and water availability via canopy damage and storm surge delivery and are expected to intensify with climate change. Plant species respond to environmental changes by making physiological adjustments in situ or through distribution changes. Three years after Hurricane Katrina, we compared functional traits and water relations among three species along the coenocline at Weeks Bay National Estuarine Research Reserve, Fairhope, Alabama, U.S.A. Based on posthurricane distribution changes for these species, we hypothesized that (1) Cladium mariscus, whose distribution expanded slightly, is responsive to increased light availability in the disturbed forest …

Discordance Between Morphological And Molecular Species Boundaries Among Caribbean Species Of The Reef Sponge Callyspongia, Melissa B. Debiasse, Michael E. Hellberg Jan 2015

Discordance Between Morphological And Molecular Species Boundaries Among Caribbean Species Of The Reef Sponge Callyspongia, Melissa B. Debiasse, Michael E. Hellberg

Faculty Publications

© 2015 The Authors. Sponges are among the most species-rich and ecologically important taxa on coral reefs, yet documenting their diversity is difficult due to the simplicity and plasticity of their morphological characters. Genetic attempts to identify species are hampered by the slow rate of mitochondrial sequence evolution characteristic of sponges and some other basal metazoans. Here we determine species boundaries of the Caribbean coral reef sponge genus Callyspongia using a multilocus, model-based approach. Based on sequence data from one mitochondrial (COI), one ribosomal (28S), and two single-copy nuclear protein-coding genes, we found evolutionarily distinct lineages were not concordant with …

Yeast High Mobility Group Protein Hmo1 Stabilizes Chromatin And Is Evicted During Repair Of Dna Double Strand Breaks, Arvind Panday, Li Juan Xiao, Anne Grove Jan 2015

Yeast High Mobility Group Protein Hmo1 Stabilizes Chromatin And Is Evicted During Repair Of Dna Double Strand Breaks, Arvind Panday, Li Juan Xiao, Anne Grove

Faculty Publications

© The Author(s) 2015. DNA is packaged into condensed chromatin fibers by association with histones and architectural proteins such as high mobility group (HMGB) proteins. However, this DNA packaging reduces accessibility of enzymes that act on DNA, such as proteins that process DNA after double strand breaks (DSBs). Chromatin remodeling overcomes this barrier. We show here that the Saccharomyces cerevisiae HMGB protein HMO1 stabilizes chromatin as evidenced by faster chromatin remodeling in its absence. HMO1 was evicted along with core histones during repair of DSBs, and chromatin remodeling events such as histone H2A phosphorylation and H3 eviction were faster in …

Derivation Of The Freshwater Fish Fauna Of Central America Revisited: Myers's Hypothesis In The Twenty-First Century, Wilfredo A. Matamoros, Caleb D. Mcmahan, Prosanta Chakrabarty, James S. Albert, Jacob F. Schaefer Jan 2015

Derivation Of The Freshwater Fish Fauna Of Central America Revisited: Myers's Hypothesis In The Twenty-First Century, Wilfredo A. Matamoros, Caleb D. Mcmahan, Prosanta Chakrabarty, James S. Albert, Jacob F. Schaefer

Faculty Publications

© The Willi Hennig Society 2014. Although attempts to understand Central American freshwater fish provincialism date to the 1960s, early efforts lacked the wealth of distributional data now available. Biogeographic work on Central American freshwater fishes has been largely descriptive and regional, and lacked a broader synthesis. Here we use parsimony analysis of endemicity (PAE) to elucidate faunistic relationships between major drainages and to delineate areas of endemism. We then perform a Brooks parsimony analysis (BPA) on the resulting areas. The PAE recovered a primary division between four Pacific and six Atlantic slope areas of endemism. In contrast, the BPA …

Reduction Of Mitochondrial Protein Mitoneet [2fe-2s] Clusters By Human Glutathione Reductase, Aaron P. Landry, Zishuo Cheng, Huangen Ding Jan 2015

Reduction Of Mitochondrial Protein Mitoneet [2fe-2s] Clusters By Human Glutathione Reductase, Aaron P. Landry, Zishuo Cheng, Huangen Ding

Faculty Publications

© 2015 Elsevier Inc. All rights reserved. The human mitochondrial outer membrane protein mitoNEET is a newly discovered target of the type 2 diabetes drug pioglitazone. Structurally, mitoNEET is a homodimer with each monomer containing an N-terminal transmembrane α helix tethered to the mitochondrial outer membrane and a C-terminal cytosolic domain hosting a redox-active [2Fe-2S] cluster. Genetic studies have shown that mitoNEET has a central role in regulating energy metabolism in mitochondria. However, the specific function of mitoNEET remains largely elusive. Here we find that the mitoNEET [2Fe-2S] clusters can be efficiently reduced by Escherichia coli thioredoxin reductase and glutathione …

Discovery And Confirmation Of Genes/Proteins Associated With Maize Aflatoxin Resistance, Z. Y. Chen, K. Rajasekaran, R. L. Brown, R. J. Sayler, D. Bhatnagar Jan 2015

Discovery And Confirmation Of Genes/Proteins Associated With Maize Aflatoxin Resistance, Z. Y. Chen, K. Rajasekaran, R. L. Brown, R. J. Sayler, D. Bhatnagar

Faculty Publications

Maize (Zea mays L.) is one of the major crops susceptible to Aspergillus flavus infection and subsequent aflatoxin contamination. Many earlier studies indicated the roles of kernel proteins, especially constitutively expressed proteins, in maize resistance to A. flavus infection and aflatoxin production. In this review, we examined the past and current efforts in identifying maize genes and proteins from kernel, rachis, and silk tissues that may play an important role in resistance to A. flavus infection and aflatoxin contamination, as well as the efforts in determining the importance or involvement of them in maize resistance through biochemical, molecular and genetics …

Atoxigenic Aspergillus Flavus Biological Control Of Aflatoxin Contamination: What Is The Mechanism?, K. E. Damann Jan 2015

Atoxigenic Aspergillus Flavus Biological Control Of Aflatoxin Contamination: What Is The Mechanism?, K. E. Damann

Faculty Publications

The term 'competitive exclusion' involving physical blockage of growth or access of the toxigenic strain to the seed target has been used to describe the mechanism of biological control of aflatoxin contamination. However, recent evidence suggests that a form of intraspecific aflatoxin inhibition requiring growth of the competing strains together during the infection process in such a way that hyphae physically interact or touch is the trigger for preventing induction of aflatoxin synthesis. This direct touch-based inhibition of aflatoxin synthesis is posited to be the mechanistic basis of biological control in this system. Evidence for this idea comes from the …

A Bayesian Phase I/Ii Clinical Trial Design In The Presence Of Informative Dropouts, Beibei Guo, Yong Zang, Ying Yuan Jan 2015

A Bayesian Phase I/Ii Clinical Trial Design In The Presence Of Informative Dropouts, Beibei Guo, Yong Zang, Ying Yuan

Faculty Publications

A phase I/II trial design utilizes both toxicity and efficacy outcomes to make the decision of dose assignment for patients. Because assessing the efficacy endpoint often requires a relatively long follow-up time, phase I/II trials are more susceptible to the missing data problem caused by informative dropouts that are correlated with treatment efficacy and toxicity. In addition, patient outcomes may not be scored quickly enough to apply decision rules that choose treatments or doses for newly accrued patients. To address these issues, we propose a Bayesian phase I/II design that jointly models efficacy, toxicity, and dropout as time-to-event data. Correlations …

Is Organismic Fitness At The Basis Of Evolutionary Theory?, Charles H. Pence, Grant Ramsey Jan 2015

Is Organismic Fitness At The Basis Of Evolutionary Theory?, Charles H. Pence, Grant Ramsey

Faculty Publications

Fitness is a central theoretical concept in evolutionary theory. Despite its importance, much debate has occurred over how to conceptualize and formalize fitness. One point of debate concerns the roles of organismic and trait fitness. In a recent addition to this debate, Elliott Sober argues that trait fitness is the central fitness concept, and that organismic fitness is of little value. In this paper, by contrast, we argue that it is organismic fitness that lies at the bases of both the conceptual role of fitness and its role as a measure of evolutionary dynamics.

Can We Identify Genes With Increased Phylogenetic Reliability?, Vinson P. Doyle, Randee E. Young, Gavin J.P. Naylor, Jeremy M. Brown Jan 2015

Can We Identify Genes With Increased Phylogenetic Reliability?, Vinson P. Doyle, Randee E. Young, Gavin J.P. Naylor, Jeremy M. Brown

Faculty Publications

© The Author(s) 2015. Topological heterogeneity among gene trees is widely observed in phylogenomic analyses and some of this variation is likely caused by systematic error in gene tree estimation. Systematic error can be mitigated by improving models of sequence evolution to account for all evolutionary processes relevant to each gene or identifying those genes whose evolution best conforms to existing models. However, the best method for identifying such genes is not well established. Here, we ask if filtering genes according to their clock-likeness or posterior predictive effect size (PPES, an inference-based measure of model violation) improves phylogenetic reliability and …

Escherichia Coli Yqja, A Member Of The Conserved Deda/Tvp38 Membrane Protein Family, Is A Putative Osmosensing Transporter Required For Growth At Alkaline Ph, Sujeet Kumar, William T. Doerrler

Faculty Publications

© 2015, American Society for Microbiology. The ability to persist and grow under alkaline conditions is an important characteristic of many bacteria. In order to survive at alkaline pH, Escherichia coli must maintain a stable cytoplasmic pH of about 7.6. Membrane cation/proton antiporters play a major role in alkaline pH homeostasis by catalyzing active inward proton transport. The DedA/Tvp38 family is a highly conserved membrane protein family of unknown function present in most sequenced genomes. YqjA and YghB are members of the E. coli DedA family with 62% amino acid identity and partially redundant functions. We have shown that E. …

Jump-Diffusion Approximation Of Stochastic Reaction Dynamics: Error Bounds And Algorithms, Arnab Ganguly, Derya Altintan, Heinz Koeppl Jan 2015

Jump-Diffusion Approximation Of Stochastic Reaction Dynamics: Error Bounds And Algorithms, Arnab Ganguly, Derya Altintan, Heinz Koeppl

Faculty Publications

Biochemical processes in living cells are comprised of reactions with vastly varying speeds and molecular counts of the reactant species. Classical deterministic or stochastic approaches to modeling often fail to exploit this multiscale nature of the reaction systems. In this paper, we propose a jump-diffusion approximation to these types of multiscale systems that couples the two traditional modeling approaches. An error bound of the proposed approximation is derived and used to partition the reactions into two sets, where one set is modeled by continuous stochastic differential equations and the other by discrete state processes. The methodology leads to a very …

Predictor-Based Tracking For Neuromuscular Electrical Stimulation, Iasson Karafyllis, Michael Malisoff, Marcio De Queiroz, Miroslav Krstic, Ruzhou Yang Jan 2015

Predictor-Based Tracking For Neuromuscular Electrical Stimulation, Iasson Karafyllis, Michael Malisoff, Marcio De Queiroz, Miroslav Krstic, Ruzhou Yang

Faculty Publications

We present a new tracking controller for neuromuscular electrical stimulation (NMES), which is an emerging technology that artificially stimulates skeletal muscles to help restore functionality to human limbs. The novelty of our work is that we prove that the tracking error globally asymptotically and locally exponentially converges to zero for any positive input delay, coupled with our ability to satisfy a state constraint imposed by the physical system. Also, our controller only requires sampled measurements of the states instead of continuous measurements and allows perturbed sampling schedules, which can be important for practical purposes. Our work is based on a …

Assessing Uncertainty In Coastal Marsh Core Sampling For Waterfowl Foods, Kevin M. Ringelman, Christopher K. Williams, John M. Coluccy Jan 2015

Assessing Uncertainty In Coastal Marsh Core Sampling For Waterfowl Foods, Kevin M. Ringelman, Christopher K. Williams, John M. Coluccy

Faculty Publications

Quantifying foraging resources available to waterfowl in different habitat types is important for estimating energetic carrying capacity. To accomplish this, most studies collect soil-core samples from the marsh substrate, sieve and sort food items, and extrapolate energy values to wetland or landscape scales. This is a costly and time-intensive process; furthermore, extrapolation methods yield energy estimates with large variances relative to the mean. From both research and management perspectives, it is important to understand sources of this variation and estimate the number of soil cores needed to reduce the variance to desired levels. Using 2,341 cores collected from freshwater and …

A Resistant-Starch Enriched Yogurt: Fermentability, Sensory Characteristics, And A Pilot Study In Children, Frank Greenway, Jolene Zheng, Kayanush Aryana, Nikhil Dhurandhar, Richard Tulley, John Finley, Michael Keenan, Roy Martin, Christine Pelkman, Douglas Olson

Faculty Publications

The rising prevalence of obesity and the vulnerability of the pediatric age group have highlighted the critical need for a careful consideration of effective, safe, remedial and preventive dietary interventions. Amylose starch (RS2) from high-amylose maize (HAM) ferments in the gut and affects body weight. One hundred and ten children, of 7-8 (n=91) or 13-14 (n=19) years of age scored the sensory qualities of a yogurt supplemented with either HAM-RS2 or an amylopectin starch. The amylopectin starch yogurt was preferred to the HAM-RS2-enriched yogurt by 7-8 year old panelists (P<0.0001). Appearance, taste, and sandiness scores given by 13- to 14-year-old panelists were more favorable for the amylopectin starch yogurt than for HAM-RS2-enriched yogurt (P<0.05). HAM-RS2 supplementation resulted in acceptable (≥6 on a 1-9 scale) sensory and hedonic ratings of the yogurt in 74% of subjects. Four children consumed a HAM-RS2-enriched yogurt for four weeks to test its fermentability in a clinical trial. Three adolescents, but not the single pre-pubertal child, had reduced stool pH (P=0.1) and increased stool short-chain fatty acids (SCFAs) (P<0.05) including increased fecal acetate (P=0.02), and butyrate (P=0.089) from resistant starch (RS) fermentation and isobutyrate (P=0.01) from protein fermentation post-treatment suggesting a favorable change to the gut microbiota. HAM-RS2 was not modified by pasteurization of the yogurt, and may be a palatable way to increase fiber intake and stimulate colonic fermentation in adolescents. Future studies are planned to determine the concentration of HAM-RS2 that offers the optimal safe and effective strategy to prevent excessive fat gain in children.

Considerable anecdotal evidence indicates that some of the most difficult concepts that both high school and undergraduate elementary-education students struggle with are those surrounding evolutionary principles, especially speciation. It’s no wonder that entry-level biology students are confused, when biologists have multiple definitions of “species.” We developed this speciation activity to provide clarity and allow students a hands-on experience with a speciation model.

Beyond Instrumentalism: A Relational Approach To Negotiation, Marc-Charles Ingerson, Kristen Bell Detienne, Katie A. Liljenquist Jan 2015

Beyond Instrumentalism: A Relational Approach To Negotiation, Marc-Charles Ingerson, Kristen Bell Detienne, Katie A. Liljenquist

Faculty Publications

Instrumentalism, the philosophy that rational people will behave in ways that promote self-interest, is often the default assumption that scholars and practitioners rely upon when interpreting and predicting human behavior in negotiations. Instrumentalism, however, need not be the only lens through which negotiators and negotiations are viewed. In this article, we discuss some of the problems associated with too heavy a reliance on instrumentalism and propose an alternative relational approach, one in which negotiators see themselves as agents embedded in a system of relationships, who are motivated to understand and advance the welfare of others. We discuss some of the …
