Ruminant Self-Medication Against Gastrointestinal Nematodes: Evidence, Mechanism, And Origins Ẫ†, Juan J. Villalba, James Miller, Eugene D. Ungar, Serge Y. Landau, John Glendinning Jan 2014

Ruminant Self-Medication Against Gastrointestinal Nematodes: Evidence, Mechanism, And Origins Ẫ†, Juan J. Villalba, James Miller, Eugene D. Ungar, Serge Y. Landau, John Glendinning

Faculty Publications

Gastrointestinal helminths challenge ruminants in ways that reduce their fitness. In turn, ruminants have evolved physiological and behavioral adaptations that counteract this challenge. Ruminants display anorexia and avoidance behaviors, which tend to reduce the incidence of parasitism. In addition, ruminants appear to learn to self-medicate against gastrointestinal parasites by increasing consumption of plant secondary compounds with antiparasitic actions. This selective feeding improves health and fitness. Here, we review the evidence for self-medication in ruminants, propose a hypothesis to explain self-medicative behaviors (based on post-ingestive consequences), and discuss mechanisms (e.g., enhanced neophilia, social transmission) that may underlie the ontogeny and spread …

Evaluation Of Alfalfa Inter-Seeding Effect On Bahiagrass Baleage Fermentation And Lactating Holstein Performance, Michael E. Mccormick, Kun Jun Han, Vinicius R. Moreira, David C. Blouin Jan 2014

Evaluation Of Alfalfa Inter-Seeding Effect On Bahiagrass Baleage Fermentation And Lactating Holstein Performance, Michael E. Mccormick, Kun Jun Han, Vinicius R. Moreira, David C. Blouin

Faculty Publications

© 2014 McCormick et al. Background: Previous research indicates that bahiagrass may be successfully conserved as baleage, but nutritive value is typically low for lactating dairy cows. The purpose of this study was to determine the effect of adding modest amounts of alfalfa forage (22%), achieved by inter-seeding alfalfa into an existing bahiagrass pasture, on baleage nutritive value and lactation performance of Holstein cows. Forage treatments employed were monoculture bahiagrass baleage (MBB; negative control), bahiagrass-alfalfa mixture baleage (BAB) and conventional corn silage (CCS; positive control). Thirty six mid lactation Holstein cows [34.8 ± 5.8 kg 3.5% fat-corrected milk and 112 …

Group 3 Late Embryogenesis Abundant Proteins From Embryos Of Artemia Franciscana: Structural Properties And Protective Abilities During Desiccation, Leaf C. Boswell, Michael A. Menze, Steven C. Hand Jan 2014

Group 3 Late Embryogenesis Abundant Proteins From Embryos Of Artemia Franciscana: Structural Properties And Protective Abilities During Desiccation, Leaf C. Boswell, Michael A. Menze, Steven C. Hand

Faculty Publications

© 2014 by The University of Chicago. All rights reserved. Group 3 late embryogenesis abundant (LEA) proteins are highly hydrophilic, and their expression is associated with desiccation tolerance in both plants and animals. Here we show that two LEA proteins from embryos of Artemia franciscana, AfrLEA2 and AfrLEA3m, are intrinsically disordered in solution but upon desiccation gain secondary structure, as measured by circular dichroism. Trifluoroethanol and sodium dodecyl sulfate are both shown to induce a-helical structure in AfrLEA2 and AfrLEA3m. Bioinformatic predictions of secondary-structure content for both proteins correspond most closely to conformations measured in the dry state. Because some …

Quantification Of Cellular Protein Expression And Molecular Features Of Group 3 Lea Proteins From Embryos Of Artemia Franciscana, Leaf C. Boswell, Daniel S. Moore, Steven C. Hand Jan 2014

Quantification Of Cellular Protein Expression And Molecular Features Of Group 3 Lea Proteins From Embryos Of Artemia Franciscana, Leaf C. Boswell, Daniel S. Moore, Steven C. Hand

Faculty Publications

Late embryogenesis abundant (LEA) proteins are highly hydrophilic, low complexity proteins whose expression has been correlated with desiccation tolerance in anhydrobiotic organisms. Here, we report the identification of three new mitochondrial LEA proteins in anhydrobiotic embryos of Artemia franciscana, AfrLEA3m-47, AfrLEA3m-43, and AfrLEA3m-29. These new isoforms are recognized by antibody raised against recombinant AfrLEA3m, the original mitochondrial-targeted LEA protein previously reported from these embryos; mass spectrometry confirms all four proteins share sequence similarity. The corresponding messenger RNA (mRNA) species for the four proteins are readily amplified from total complementary DNA (cDNA) prepared from embryos. cDNA sequences of the four mRNAs …

Modulation Of Vacuolar Ph Is Required For Replication Of Edwardsiella Ictaluri In Channel Catfish Macrophages, Wes A. Baumgartner, Lidiya Dubytska, Matthew L. Rogge, Peter J. Mottram, Ronald L. Thune Jan 2014

Modulation Of Vacuolar Ph Is Required For Replication Of Edwardsiella Ictaluri In Channel Catfish Macrophages, Wes A. Baumgartner, Lidiya Dubytska, Matthew L. Rogge, Peter J. Mottram, Ronald L. Thune

Faculty Publications

Previous in vitro work demonstrated that Edwardsiella ictaluri produces an acid-activated urease that can modulate environmental pH through the production of ammonia from urea. Additional work revealed that expression of the E. ictaluri type III secretion system (T3SS) is upregulated by acidic pH. Both the urease and the T3SS were previously shown to be essential to intracellular replication. In this work, fluorescence microscopy with LysoTracker Red DND-99 (LTR) indicated that E. ictaluri-containing vacuoles (ECV) became acidified following ingestion by head kidney-derived macrophages (HKDM). In vivo ratiometric imaging demonstrated a lowered ECV pH, which fell to as low as pH 4 …

Kif3a Promotes Proliferation And Invasion Via Wnt Signaling In Advanced Prostate Cancer, Zun Liu, Ryan E. Rebowe, Zemin Wang, Yingchun Li, Zehua Wang, John S. Depaolo, Jianhui Guo, Chiping Qian, Wanguo Liu

Faculty Publications

Aberrant activation of the Wnt/β-catenin signaling pathway is a critical event in advanced prostate cancer, but the genetic alterations that activate theWnt signaling pathway in many other cancers are rarely observed in prostate cancer. Other molecular mechanisms that regulate the Wnt signaling pathway in prostate cancer remain to be identified. Here, it is demonstrated that KIF3a, a subunit of kinesin-II motor protein, functions as an agonist of the Wnt signaling pathway in prostate cancer. KIF3a is upregulated in the majority of human prostate cancer cell lines and primary tumor biopsies. The expression levels of KIF3a correlate with a higher Gleason …

Host Range Tests Reveal Paectes Longiformis Is Not A Suitable Biological Control Agent For The Invasive Plant Schinus Terebinthifolia, Veronica Manrique, Rodrigo Diaz, Todd Condon, W. A. Overholt

Faculty Publications

© 2014, International Organization for Biological Control (IOBC). The most critical step during a weed biological control program is determination of a candidate agent’s host range. Despite rigorous protocols and extensive testing, there are still concerns over potential non-target effects following field releases. With the objective to improve risk assessment in biological control, no-choice and choice testing followed by a multiple generation study were conducted on the leaf-defoliator, Paectes longiformis Pogue (Lepidoptera: Euteliidae). This moth is being investigated as a biological control agent of Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), which is one of the worst invasive plant species in Florida, …

Faculty Publications

© The Author 2014. Published by Oxford University Press on behalf of the Entomological Society of America. A chironomid midge, Cricotopus lebetis (Sublette) (Diptera: Chironomidae), was discovered attacking the apical meristems of Hydrilla verticillata (L.f. Royle) in Crystal River, Citrus Co., Florida in 1992. The larvae mine the stems of H. verticillata and cause basal branching and stunting of the plant. Temperature-dependent development, cold tolerance, and the potential distribution of the midge were investigated. The results of the temperature-dependent development study showed that optimal temperatures for larval development were between 20 and 30°C, and these data were used to construct …

Differential Effects Of Akt Isoforms On Somatic Cell Reprogramming, Yong Tang, Zongliang Jiang, Yan Luo, Xueming Zhao, Ling Wang, Carol Norris, Xiuchun Cindy Tian Jan 2014

Differential Effects Of Akt Isoforms On Somatic Cell Reprogramming, Yong Tang, Zongliang Jiang, Yan Luo, Xueming Zhao, Ling Wang, Carol Norris, Xiuchun Cindy Tian

Faculty Publications

© 2014. Akt plays an important role in cell growth, proliferation and survival. The specific roles of the three Akt isoforms in somatic cell reprogramming have not been investigated. Here we report that, during iPSC generation, enhanced Akt1 activity promotes complete reprogramming mainly through increased activation of Stat3 in concert with leukemia inhibitory factor (LIF) and, to a lesser extent, through promotion of colony formation. Akt1 augments Stat3 activity through activation of mTOR and upregulation of LIF receptor expression. Similarly, enhanced Akt2 or Akt3 activation also promotes reprogramming and coordinates with LIF to activate Stat3. Blocking Akt1 or Akt3 but …

Phenylalanine Residues At The Carboxyl Terminus Of The Herpes Simplex Virus 1 Ul20 Membrane Protein Regulate Cytoplasmic Virion Envelopment And Infectious Virus Production, Anu Susan Charles, Vladimir N. Chouljenko, Nithya Jambunathan, Ramesh Subramanian, Peter Mottram, Konstantin G. Kousoulas Jan 2014

Phenylalanine Residues At The Carboxyl Terminus Of The Herpes Simplex Virus 1 Ul20 Membrane Protein Regulate Cytoplasmic Virion Envelopment And Infectious Virus Production, Anu Susan Charles, Vladimir N. Chouljenko, Nithya Jambunathan, Ramesh Subramanian, Peter Mottram, Konstantin G. Kousoulas

Faculty Publications

The herpes simplex virus type 1 (HSV-1) UL20 gene encodes a 222-amino-acid nonglycosylated envelope protein which forms a complex with viral glycoprotein K (gK) that functions in virion envelopment, egress, and virus-induced cell fusion. To investigate the role of the carboxyl terminus of the UL20 protein (UL20p) in cytoplasmic virion envelopment, a cadre of mutant viruses was constructed and characterized. The deletion of six amino acids from the carboxyl terminus of UL20p caused an approximately 1-log reduction in infectious virus production compared to that of the wild-type virus. Surprisingly, a phenylalanine-toalanine replacement at amino acid position 210 caused a gain-of-function …

Development Of Microsatellites For Population Genetic Analyses Of Tabanus Nigrovittatus (Diptera: Tabanidae), Claudia Husseneder, Jennifer R. Delatte, Jeremy Krumholt, Lane D. Foil

Faculty Publications

ABSTRACT The greenhead horse fly, Tabanus nigrovittatus Macquart (Diptera: Tabanidae), is frequently found in coastal marshes of the Eastern United States. The females are autogenous (i.e., able to develop eggs without a bloodmeal), but they become a considerable pest to both humans and animals when they pursue a source of blood protein to produce additional eggs. In this study, we identified microsatellite markers to provide first insight into the population genetic structure of this notorious pest species. Because no prior genomic information was available for T. nigrovittatus,weused direct shotgun pyrosequencing technology to characterize microsatellite loci. Approximately 10% of the 105,634 …

Parental Care In The Cuatro Ciénegas Cichlid, Herichthys Minckleyi (Teleostei: Cichlidae), Ronald G. Oldfield, Kapil Mandrekar, M. Xavier Nieves, Dean A. Hendrickson, Prosanta Chakrabarty, Brook O. Swanson, Hans A. Hofmann Jan 2014

Parental Care In The Cuatro Ciénegas Cichlid, Herichthys Minckleyi (Teleostei: Cichlidae), Ronald G. Oldfield, Kapil Mandrekar, M. Xavier Nieves, Dean A. Hendrickson, Prosanta Chakrabarty, Brook O. Swanson, Hans A. Hofmann

Faculty Publications

© 2014, Springer International Publishing Switzerland. Behavioral studies have often examined parental care by measuring phenotypic plasticity of behavior within a species. Phylogenetic studies have compared parental care among species, but only at broad categories (e.g., care vs. no care). Here we provide a detailed account that integrates phylogenetic analysis with quantitative behavioral data to better understand parental care behavior in the Cuatro Ciénegas cichlid, Herichthys minckleyi. We found that H. minckleyi occurs in a clade of sexually monochromatic or weakly dichromatic monogamous species, but that male and female H. minckleyi have dramatically different reproductive coloration patterns, likely as a …

Adaptation To Ephemeral Habitat May Overcome Natural Barriers And Severe Habitat Fragmentation In A Fire-Dependent Species, The Bachman's Sparrow (Peucaea Aestivalis), Blain Cerame, James A. Cox, Robb T. Brumfield, James W. Tucker, Sabrina S. Taylor

Faculty Publications

Bachman's Sparrow (Peucaea aestivalis) is a fire-dependent species that has undergone range-wide population declines in recent decades. We examined genetic diversity in Bachman's Sparrows to determine whether natural barriers have led to distinct population units and to assess the effect of anthropogenic habitat loss and fragmentation. Genetic diversity was examined across the geographic range by genotyping 226 individuals at 18 microsatellite loci and sequencing 48 individuals at mitochondrial and nuclear genes. Multiple analyses consistently demonstrated little genetic structure and high levels of genetic variation, suggesting that populations are panmictic. Based on these genetic data, separate management units/subspecies designations or translocations …

Engineering Behavior And Characterization Of Biomass Ashes Using Geotechnical Measurement Techniques, Francisco Javier Grau Sacoto Jan 2014

Engineering Behavior And Characterization Of Biomass Ashes Using Geotechnical Measurement Techniques, Francisco Javier Grau Sacoto

LSU Master's Theses

Biomass, the organic material derived from plants or animals in a biological process, has rapidly become a topic of worldwide interest. The need to find new types of renewable energy sources has led to the use of natural materials as an economic, sustainable and environmental alternative. Biomass can be used to produce biofuel after a conversion process. The combustion of biomass matter –which is mainly produced in industrial plants- becomes biomass ash, which contains macronutrients and micronutrients. Currently, the recycling potential is wasted and most of the biomass ash is dumped without control or just disposed in landfills. The main …

The Role Of Technology In Teaching And Learning Chinese Characters, Hong Zhan, Hsiu-Jen Cheng Jan 2014

The Role Of Technology In Teaching And Learning Chinese Characters, Hong Zhan, Hsiu-Jen Cheng

Publications

Chinese characters have been an obstacle preventing the development of Chinese proficiency for learners of Chinese whose native language does not have characters. A substantial literature review identified linguistic, pedagogical, and political factors as causes of those difficulties. Tone changes represent different meanings of a word. Compound characters include the phonetic component radicals that do not always sound the same as the phonetic radicals. These unique linguistic features of the Chinese language add even more challenges for learning of Chinese as a foreign language (CFL). Technology integration has been found to facilitate the teaching and learning foreign languages in many …

Variations In Intra- And Interspecific Response To Mobbing Calls By The Black-Capped Chickadee (Poecile Atricapillus), Katerina M. Faust Jan 2014

Variations In Intra- And Interspecific Response To Mobbing Calls By The Black-Capped Chickadee (Poecile Atricapillus), Katerina M. Faust

Honors Theses

Mobbing calls are produced by a variety of bird species in response to predator sightings. These mobbing calls often function in intraspecific recruitment, but have recently been shown to have an interspecific response component as well. The mobbing calls produced by the Black-capped Chickadee (Poecile atricapillus) are distinct and encode information about the threat level of the predator. Conservation biologists often use playbacks of chickadee mobbing calls to detect species of birds and numbers of individuals in an area with higher accuracy than counts conducted without the use of playbacks. In this study, the factors that could potentially …

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin Jan 2014

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin

Honors Theses

The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England’s …

New Perspectives On The Northampton Communion Controversy Iii: Count Vavasor's Tirade And The Second Council, 1751, Douglas L. Winiarski

Religious Studies Faculty Publications

Jonathan Edwards’ fateful decision to repudiate the church admission practices of his grandfather, Solomon Stoddard, provoked a bitter dispute with his parishioners that led to his dismissal in 1750. Scholars have long debated the meaning of this crucial turning point in Edwards’ pastoral career. For early biographers, the Northampton communion controversy served as an index of eighteenth-century religious decline. More recent studies situate Edwards’ dismissal within a series of local quarrels over his salary, the “Bad Book” affair, conflicts with the Williams family, and the paternity case of Elisha Hawley. This essay is the first a series that reexamines the …

The Distance Travelled Between Points A And B Depends On Differences In Reinforcement : A Translational Evaluation Of Transitions, Joshua Jessel Jan 2014

The Distance Travelled Between Points A And B Depends On Differences In Reinforcement : A Translational Evaluation Of Transitions, Joshua Jessel

Doctoral Dissertations - College of Arts and Sciences

"In the experimental literature, transitions with nonhuman animals are typically framed as inescapable changes in signaled reinforcement schedules resulting in a pause in responding unique to switches from rich-to-lean schedules of reinforcement. Pausing is considered to be a function of the aversive qualities of the contrasting reinforcement schedules. By contrast, transitions are typically framed in applied research as physical changes in location evoking problem behavior maintained by the escape of a programmed aversive event and/or resumption of a programmed preferred event. We attempted to translate the basic framing of transitions to behaviors and contexts of social significance (Experiment 1), create …

Using Measures Of Risk Perception To Predict Information Security Behavior: Insights From Electroencephalography (Eeg), Anthony Vance, Bonnie Anderson, C. Brock Kirwan, David Eargle Jan 2014

Using Measures Of Risk Perception To Predict Information Security Behavior: Insights From Electroencephalography (Eeg), Anthony Vance, Bonnie Anderson, C. Brock Kirwan, David Eargle

Faculty Publications

Users' perceptions of risks have important implications for information security, as the actions of individual users can compromise entire systems. Therefore, there is a critical need to understand how users perceive and respond to information security risks. Previous research on perceptions of information security risk has chiefly relied on self-reported measures. Although these studies are valuable, risk perceptions are often associated with feelings—such as fear or doubt—that are difficult to measure accurately using survey instruments. Additionally, it is unclear how these self-reported measures map to actual security behavior. This paper contributes by demonstrating that risk-taking behavior is effectively predicted using …
