Characterization Of Virus-Encoded Rna Interference Suppressors In Caenorhabditis Elegans, Xunyang Guo, Rui Lu May 2013

Characterization Of Virus-Encoded Rna Interference Suppressors In Caenorhabditis Elegans, Xunyang Guo, Rui Lu

Faculty Publications

In fungi, plants, and invertebrates, antiviral RNA interference (RNAi) directed by virus-derived small interfering RNAs (siRNAs) represents a major antiviral defense that the invading viruses have to overcome in order to establish infection. As a counterdefense mechanism, viruses of these hosts produce diverse classes of proteins capable of suppressing the biogenesis and/or function of viral siRNAs. This RNA-directed viral immunity (RDVI) in the nematode Caenorhabditis elegans is known to exhibit some unique features. Currently, little is known about viral suppression of RNAi in C. elegans. Here, we show that ectopic expression of the B2 protein encoded by Flock House virus …

Molecular Characterization And Functional Significance Of The Vti Family Of Snare Proteins In Tick Salivary Glands, Ashley M. Villarreal, Steven W. Adamson, Rebecca E. Browning, Khemraj Budachetri, Muhammad Sohail Sajid, Shahid Karim

Faculty Publications

Exocytosis involves membrane fusion between secretory vesicles and the plasma membrane. The Soluble N-ethylmaleimide-sensitive factor attachment proteins (SNAPs) and their receptor proteins (SNAREs) interact to fuse vesicles with the membrane and trigger the release of their sialosecretome out of the tick salivary gland cells. In this study, we examined the functional significance of the Vti family of SNARE proteins of blood-feeding Amblyomma maculatum and Amblyomma americanum. Vti1A and Vti1B have been implicated in multiple functional roles in vesicle transport. QRT-PCR studies demonstrated that the highest transcriptional expression of vti1a and vti1b genes occurs in unfed salivary glands, suggesting that …

Socio-Ecology Of The Marsh Rice Rat (Oryzomys Palustris) And The Spatio-Temporal Distribution Of Bayou Virus In Coastal Texas, Tyla S. Holsomback, Christopher J. Van Nice, Rachel N. Clark, Alisa A. Abuzeineh, Jorge Salazar-Bravo May 2013

Socio-Ecology Of The Marsh Rice Rat (Oryzomys Palustris) And The Spatio-Temporal Distribution Of Bayou Virus In Coastal Texas, Tyla S. Holsomback, Christopher J. Van Nice, Rachel N. Clark, Alisa A. Abuzeineh, Jorge Salazar-Bravo

Faculty Publications

Along the southeastern coast of the United States of America (USA), the marsh rice rat (Oryzomys palustris) is the primary host for the hantavirus genotype Bayou. According to the socio-ecological model for a territorial, polygamous species, females should be distributed across space and time by habitat resources and predation risks, whereas males should space themselves according to the degree of female aggregation and reproductive synchrony. To investigate how females affect the male-male transmission paradigm of Bayou virus, rodents were captured, marked, released, and re-captured in two macrohabitat types across a 30-month period. Microhabitat cover variables were quantified around …

Faculty Publications

Aloe vera, a common ingredient in cosmetics, is increasingly being consumed as a beverage supplement. Although consumer interest in aloe likely stems from its association with several health benefits, a concern has also been raised by a National Toxicology Program Report that a nondecolorized whole leaf aloe vera extract taken internally by rats was associated with intestinal mucosal hyperplasia and ultimately malignancy. We tested a decolorized whole leaf (DCWL) aloe vera, treated with activated charcoal to remove the latex portion of the plant, for genotoxicity in bacteria, acute/subacute toxicity in B6C3F1 mice, and subchronic toxicity in F344 rats. We found …

An Inverse Relationship Between Production And Export Efficiency In The Southern Ocean, Kanchan Maiti, Matthew A. Charette, Ken O. Buesseler, Mati Kahru Apr 2013

An Inverse Relationship Between Production And Export Efficiency In The Southern Ocean, Kanchan Maiti, Matthew A. Charette, Ken O. Buesseler, Mati Kahru

Faculty Publications

In the past two decades, a number of studies have been carried out in the Southern Ocean to look at export production using drifting sediment traps and thorium-234 based measurements, which allows us to reexamine the validity of using the existing relationships between production, export efficiency, and temperature to derive satellite-based carbon export estimates in this region. Comparisons of in situ export rates with modeled rates indicate a two to fourfold overestimation of export production by existing models. Comprehensive analysis of in situ data indicates two major reasons for this difference: (i) in situ data indicate a trend of decreasing …

Controls On Dissolved Organic Carbon Quantity And Chemical Character In Temperate Rivers Of North America, Kevin W. Hanley, Wilfred M. Wollheim, Joseph Salisbury, Thomas Huntington, George Aiken Apr 2013

Controls On Dissolved Organic Carbon Quantity And Chemical Character In Temperate Rivers Of North America, Kevin W. Hanley, Wilfred M. Wollheim, Joseph Salisbury, Thomas Huntington, George Aiken

Faculty Publications

Understanding the processes controlling the transfer and chemical composition of dissolved organic carbon (DOC) in freshwater systems is crucial to understanding the carbon cycle and the effects of DOC on water quality. Previous studies have identified watershed‐scale controls on bulk DOC flux and concentration among small basins but fewer studies have explored controls among large basins or simultaneously considered the chemical composition of DOC. Because the chemical character of DOC drives riverine biogeochemical processes such as metabolism and photodegradation, accounting for chemical character in watershed‐scale studies will improve the way bulk DOC variability in rivers is interpreted. We analyzed DOC …

The Hemophore Hasa From Yersinia Pestis (HasaYp) Coordinates Hemin With A Single Residue, Tyr75, And With Minimal Conformational Change, Ritesh Kumar, Scott Lovell, Hirotoshi Matsumura, Kevin P. Battaile, Pierre Moënne-Loccoz, Mario Rivera Apr 2013

The Hemophore Hasa From Yersinia Pestis (HasaYp) Coordinates Hemin With A Single Residue, Tyr75, And With Minimal Conformational Change, Ritesh Kumar, Scott Lovell, Hirotoshi Matsumura, Kevin P. Battaile, Pierre Moënne-Loccoz, Mario Rivera

Faculty Publications

Hemophores from Serratia marcescens (HasAsm) and Pseudomonas aeruginosa (HasAp) bind hemin between two loops, which harbor the axial ligands H32 and Y75. Hemin binding to the Y75 loop triggers closing of the H32 loop and enables binding of H32. Because Yersinia pestis HasA (HasA yp) presents a Gln at position 32, we determined the structures of apo- and holo-HasAyp. Surprisingly, the Q32 loop in apo-HasA yp is already in the closed conformation, but no residue from the Q32 loop binds hemin in holo-HasAyp. In agreement with the minimal reorganization between the apo- and holo-structures, the hemin on-rate is too fast …

Multi-Year Salutary Effects Of Windstorm And Fire On River Cane, Paul R. Gagnon, Heather A. Passmore, William J. Platt Apr 2013

Multi-Year Salutary Effects Of Windstorm And Fire On River Cane, Paul R. Gagnon, Heather A. Passmore, William J. Platt

Faculty Publications

Canebrakes are monodominant stands of cane (Arundinaria gigantea [Walter] Muhl.), a bamboo native to and once prominent in the southeastern USA. Canebrakes were important wildlife habitat within the bottomland hardwood forest ecosystem. They have been reduced in areal coverage by an estimated 98% since European settlement due to land conversion and the drastic alteration of disturbance regimes in their floodplain habitat. Ongoing canebrake restoration efforts are hampered by incomplete understanding of the role of natural disturbance in cane ecology. We used a large tornado blow down and multiple prescribed fires to quantify the response of cane to the sequential disturbances …

Differential Undertaking Response Of A Lower Termite To Congeneric And Conspecific Corpses, Qian Sun, Kenneth F. Haynes, Xuguo Zhou Apr 2013

Differential Undertaking Response Of A Lower Termite To Congeneric And Conspecific Corpses, Qian Sun, Kenneth F. Haynes, Xuguo Zhou

Faculty Publications

Undertaking behaviour is an essential activity in social insects. Corpses are often recognized by a postmortem change in a chemical signature.Reticulitermes flavipesresponded to corpses within minutes of death. This undertaking behaviour did not change with longer postmortem time (24 h); however,R.flavipes exhibited distinctively different behaviours toward dead termites from various origins. Corpses of the congeneric species, Reticulitermes virginicus,were buried onsite by workers with a large group of soldiers guarding the burial site due to the risk of interspecific competition; while dead conspecifics, regardless of colony origin, were pulled back into the holding chamber for nutrient recycling and hygienic purposes.

Horizontal Cooling Towers: Riverine Ecosystem Services And The Fate Of Thermoelectric Heat In The Contemporary Northeast Us, Robert J. Stewart, Wilfred M. Wollheim, Ariel Miara, Charles J. Vorosmarty, Balazs M. Fekete, Richard B. Lammers, Bernice Rosenzweig Apr 2013

Horizontal Cooling Towers: Riverine Ecosystem Services And The Fate Of Thermoelectric Heat In The Contemporary Northeast Us, Robert J. Stewart, Wilfred M. Wollheim, Ariel Miara, Charles J. Vorosmarty, Balazs M. Fekete, Richard B. Lammers, Bernice Rosenzweig

Faculty Publications

The electricity sector is dependent on rivers to provide ecosystem services that help regulate excess heat, either through provision of water for evaporative cooling or by conveying, diluting and attenuating waste heat inputs. Reliance on these ecosystem services alters flow and temperature regimes, which impact fish habitat and other aquatic ecosystem services. We demonstrate the contemporary (2000–2010) dependence of the electricity sector on riverine ecosystem services and associated aquatic impacts in the Northeast US, a region with a high density of thermoelectric power plants. We quantify these dynamics using a spatially distributed hydrology and water temperature model (the framework for …

Clinical And Molecular Models Of Glioblastoma Multiforme Survival, R. Piccolo Stephen, J. Frey Lewis Apr 2013

Clinical And Molecular Models Of Glioblastoma Multiforme Survival, R. Piccolo Stephen, J. Frey Lewis

Faculty Publications

Glioblastoma multiforme (GBM), a highly aggressive form of brain cancer, results in a median survival of 12–15 months. For decades, researchers have explored the effects of clinical and molecular factors on this disease and have identified several candidate prognostic markers. In this study, we evaluated the use of multivariate classification models for differentiating between subsets of patients who survive a relatively long or short time. Data for this study came from The Cancer Genome Atlas (TCGA), a public repository containing clinical, treatment, histological and biomolecular variables for hundreds of patients. We applied variable-selection and classification algorithms in a cross-validated design …

Early Prenatal Food Supplementation Ameliorates Thenegative Association Of Maternal Stress With Birth Size In A Randomised Trial, Amy L. Frith, Ruchira T. Naved, Lars Ake Persson, Edward A. Frongillo Jr.

Faculty Publications

Low birthweight increases the risk of infant mortality, morbidity and poor development. Maternal nutrition and stress influence birth size, but their combined effect is not known.We hypothesised that an early-invitation time to start a prenatal food supplementation programme could reduce the negative influence of prenatal maternal stress on birth size, and that effect would differ by infant sex. A cohort of 1041 pregnant women, who had delivered an infant, June 2003–March 2004, was sampled from among 3267 in the randomised controlled trial, Maternal Infant Nutritional Interventions Matlab, conducted in Matlab, Bangladesh. At 8 weeks gestation, women were randomly assigned an …

Rampant Polyphyly Indicates Cryptic Diversity In A Clade Of Neotropical Flycatchers (Aves: Tyrannidae), Frank E. Rheindt, Andrés M. Cuervo, Robb T. Brumfield Apr 2013

Rampant Polyphyly Indicates Cryptic Diversity In A Clade Of Neotropical Flycatchers (Aves: Tyrannidae), Frank E. Rheindt, Andrés M. Cuervo, Robb T. Brumfield

Faculty Publications

Polyphyletic arrangements in DNA phylogenies are often indicators of cryptic species diversity masked by erroneous taxonomic treatments that are frequently based on morphological data. Although mitochondrial (mt)DNA polyphyly is detected relatively rarely in phylogenetic studies, it has recently been found in a variety of tyrant-flycatcher (Tyrannidae) groups. In the present study, we provide a DNA phylogeny for a mitochondrial and a nuclear locus with a complete species sampling in Zimmerius flycatchers, showing that the genus is characterized by multiple mtDNA polyphyly. Based on phylogenetic and life-history information, we suggest the elevation of a number of taxa to species status, leading …

School Bullying Victimization As An Educational Disability, Douglas E. Abrams Apr 2013

School Bullying Victimization As An Educational Disability, Douglas E. Abrams

Faculty Publications

Parts I and II of this essay urge school authorities, parents, and other concerned citizens to perceive bullying victimization as a disability that burdens targeted students. Since 1975, the federal Individuals with Disabilities Education Act (IDEA) has guaranteed “full educational opportunity to all children with disabilities” in every state. The IDEA reaches both congenital disabilities and disabilities that, like bullying victimization, stem from events or circumstances unrelated to biology or birth. To set the context for perceiving bullying victimization as an educational disability, Part I describes the public schools' central role in protecting bullied students, and then briefly discusses the …

Improved Tolerance To Salt And Water Stress In Drosophila Melanogaster Cells Conferred By Late Embryogenesis Abundant Protein, Matthew R. Marunde, Dilini A. Samarajeewa, John Anderson, Shumin Li, Steven C. Hand, Michael A. Menze

Faculty Publications

Mechanisms that govern anhydrobiosis involve the accumulation of highly hydrophilic macromolecules, such as late embryogenesis abundant (LEA) proteins. Group 1 LEA proteins comprised of 181 (AfLEA1.1) and 197 (AfLEA1.3) amino acids were cloned from embryos of Artemia franciscana and expressed in Drosophila melanogaster cells (Kc167). Confocal microscopy revealed a construct composed of green fluorescent protein (GFP) and AfLEA1.3 accumulates in the mitochondria (AfLEA1.3-GFP), while AfLEA1.1-GFP was found in the cytoplasm. In the presence of mixed substrates, oxygen consumption was statistically identical for permeabilized Kc167 control and Kc167-AfLEA1.3 cells. Acute titrations of permeabilized cells with NaCl up to 500mM led to …

The Urban Health Transition Hypothesis: Empirical Evidence Of An Avian Influenza Kuznets Curve In Vietnam?, James Herbert Spencer Apr 2013

The Urban Health Transition Hypothesis: Empirical Evidence Of An Avian Influenza Kuznets Curve In Vietnam?, James Herbert Spencer

Faculty Publications

The literature on development has focused on the concept of transition in understanding the emergent challenges facing poor but rapidly developing countries. Scholars have focused extensively on the health and urban transitions associated with this change and, in particular, its use for understanding emerging infectious diseases. However, few have developed explicit empirical measures to quantify the extent to which a transitions focus is useful for theory, policy, and practice. Using open source data on avian influenza in 2004 and 2005 and the Vietnam Census of Population and Housing, this paper introduces the Kuznets curve as a tool for empirically estimating …

Enhanced Nucleate Boiling On Horizontal Hydrophobic-Hydrophilic Carbon Nanotube Coatings, Xianming Dai, Xinyu Huang, Fanghao Yang, Xiaodong Li, Joshua Sightler, Yingchao Yang, Chen Li

Faculty Publications

Ideal hydrophobic-hydrophilic composite cavities are highly desired to enhance nucleate boiling. However, it is challenging and costly to fabricate these types of cavities by conventional micro/nano fabrication techniques. In this study, a type of hydrophobic-hydrophilic composite interfaces were synthesized from functionalized multiwall carbon nanotubes by introducing hydrophilic functional groups on the pristine multiwall carbon nanotubes. This type of carbon nanotube enabled hydrophobic-hydrophilic composite interfaces were systematically characterized. Ideal cavities created by the interfaces were experimentally demonstrated to be the primary reason to substantially enhance nucleate boiling

Diel Vertical Movements Of A Scalloped Hammerhead, Sphyrna Lewini, In The Northern Gulf Of Mexico, Eric R. Hoffmayer, James S. Franks, William B. Driggers, Paul W. Howey

Faculty Publications

Despite the circumglobal distribution of scalloped hammerheads, Sphyrna lewini (Griffith and Smith, 1834), little information is available regarding fine-scale movement and habitat use patterns for this species. Over a 27-d period, data were collected on diel habitat use and environmental preferences of a 240 cm (total length) female S. lewini. The shark exhibited a consistent and repeated diel vertical movement pattern, making more than 76 deep nighttime dives; the maximum depth reached was 964 m, where the temperature was 5.8 degrees C. The purpose of the nightly oscillatory deep diving pattern is unknown but could possibly represent feeding behavior. These …

Quantifying Intrapopulation Variability In Stable Isotope Data For Spotted Seatrout (Cynoscion Nebulosus), Richard S. Fulford, Kevin Dillon Apr 2013

Quantifying Intrapopulation Variability In Stable Isotope Data For Spotted Seatrout (Cynoscion Nebulosus), Richard S. Fulford, Kevin Dillon

Faculty Publications

Stable isotope (SI) values of carbon (delta C-13) and nitrogen (delta N-15) are useful for determining the trophic connectivity between species within an ecosystem, but interpretation of these data involves important assumptions about sources of intrapopulation variability. We compared intrapopulation variability in delta C-13 and delta N-15 for an estuarine omnivore, Spotted Seatrout (Cynoscion nebulosus), to test assumptions and assess the utility of SI analysis for delineation of the connectivity of this species with other species in estuarine food webs. Both delta C-13 and delta N-15 values showed patterns of enrichment in fish caught from coastal to offshore sites and …
