Effects Of Biogents Sentinel Trap Field Placement On Capture Rates Of Adult Asian Tiger Mosquitoes, Aedes Albopictus, Taryn N. Crepeau, Sean P. Healy, Kristen Bartlett-Healy, Isik Unlu, Ary Farajollahi, Dina M. Fonseca

Faculty Publications

The Biogents® Sentinel (BGS) trap is the standard tool to monitor adult Aedes (Stegomyia) albopictus (Skuse) (Diptera: Culicidae), the Asian tiger mosquito. BGS traps are commonly placed in residential properties during surveillance operations, but locations within properties may have significant differences in ambient light, temperature, and humidity (e.g. between a sunlit lawn and shady underbrush). We examined the effect of BGS trap placement on Ae. albopictus capture rates in three residential properties in Monmouth County, New Jersey, USA. In each property we visually selected locations as shade, partial shade, and sun. Traps in "partial shade" locations were under vegetation and …


Corpse Management In Social Insects, Qian Sun, Xuguo Zhou Mar 2013

Corpse Management In Social Insects, Qian Sun, Xuguo Zhou

Faculty Publications

Undertaking behavior is an essential adaptation to social life that is critical for colony hygiene in enclosed nests. Social insects dispose of dead individuals in various fashions to prevent further contact between corpses and living members in a colony. Focusing on three groups of eusocial insects (bees, ants, and termites) in two phylogenetically distant orders (Hymenoptera and Isoptera), we review mechanisms of death recognition, convergent and divergent behavioral re-sponses toward dead individuals, and undertaking task allocation from the perspective of division of labor. Distinctly different solutions (e.g., corpse removal, burial and cannibalism) have evolved, independently, in the holometabolous hymenopterans and …

A physically anchored consensus map is foundational to modern genomics research; however, construction of such a map in oat (Avena sativa L., 2n = 6x = 42) has been hindered by the size and complexity of the genome, the scarcity of robust molecular markers, and the lack of aneuploid stocks. Resources developed in this study include a modified SNP discovery method for complex genomes, a diverse set of oat SNP markers, and a novel chromosome-deficient SNP anchoring strategy. These resources were applied to build the first complete, physically-anchored consensus map of hexaploid oat. Approximately 11,000 high-confidence in silico SNPs were …


H3k4 Methyltransferase Set1 Is Involved In Maintenance Of Ergosterol Homeostasis And Resistance To Brefeldin A, Paul F. South, Kayla M. Harmeyer, Nina D. Serratore, Scott D. Briggs Mar 2013

H3k4 Methyltransferase Set1 Is Involved In Maintenance Of Ergosterol Homeostasis And Resistance To Brefeldin A, Paul F. South, Kayla M. Harmeyer, Nina D. Serratore, Scott D. Briggs

Faculty Publications

Set1 is a conserved histone H3 lysine 4 (H3K4) methyltransferase that exists as a multisubunit complex. Although H3K4 methylation is located on many actively transcribed genes, few studies have established a direct connection showing that loss of Set1 and H3K4 methylation results in a phenotype caused by disruption of gene expression. In this study, we determined that cells lacking Set1 or Set1 complex members that disrupt H3K4 methylation have a growth defect when grown in the presence of the antifungal drug Brefeldin A (BFA), indicating that H3K4 methylation is needed for BFA resistance. To determine the role of Set1 in …


Iron Binding Activity Is Essential For The Function Of Isca In Iron-Sulphur Cluster Biogenesis, Aaron P. Landry, Zishuo Cheng, Huangen Ding Mar 2013

Iron Binding Activity Is Essential For The Function Of Isca In Iron-Sulphur Cluster Biogenesis, Aaron P. Landry, Zishuo Cheng, Huangen Ding

Faculty Publications

Iron-sulphur cluster biogenesis requires coordinated delivery of iron and sulphur to scaffold proteins, followed by transfer of the assembled clusters from scaffold proteins to target proteins. This complex process is accomplished by a group of dedicated iron-sulphur cluster assembly proteins that are conserved from bacteria to humans. While sulphur in iron-sulphur clusters is provided by l-cysteine via cysteine desulfurase, the iron donor(s) for iron-sulphur cluster assembly remains largely elusive. Here we report that among the primary iron-sulphur cluster assembly proteins, IscA has a unique and strong binding activity for mononuclear iron in vitro and in vivo. Furthermore, the ferric iron …


Long Prereproductive Selection And Divergence By Depth In A Caribbean Candelabrum Coral, Carlos Prada, Michael E. Hellberg Mar 2013

Long Prereproductive Selection And Divergence By Depth In A Caribbean Candelabrum Coral, Carlos Prada, Michael E. Hellberg

Faculty Publications

Long-lived corals, the foundation of modern reefs, often follow ecological gradients, so that populations or sister species segregate by habitat. Adaptive divergence maintains sympatric congeners after secondary contact or may even generate species by natural selection in the face of gene flow. Such ecological divergence, initially between alternative phenotypes within populations, may be aided by immigrant inviability, especially when a long period separates larval dispersal and the onset of reproduction, during which selection can sort lineages to match different habitats. Here, we evaluate the strength of one ecological factor (depth) to isolate populations by comparing the genes and morphologies of …

The anti-AIDS drug rilpivirine undergoes conformational changes to bind HIV-1 reverse transcriptase (RT), which is an essential enzyme for the replication of HIV. These changes allow it to retain potency against mutations that otherwise would render the enzyme resistant. Here we report that water molecules play an essential role in this binding process. Femtosecond experiments and theory expose the molecular level dynamics of rilpivirine bound to HIV-1 RT. Two nitrile substituents, one on each arm of the drug, are used as vibrational probes of the structural dynamics within the binding pocket. Two-dimensional vibrational echo spectroscopy reveals that one nitrile group …


Vitronectin Inhibits Efferocytosis Through Interactions With Apoptotic Cells As Well As With Macrophages, Hong Beom Bae, Jean Marc Tadie, Shaoning Jiang, Dae Won Park, Celeste P. Bell, Lawrence C. Thompson, Cynthia B. Peterson, Victor J. Thannickal, Edward Abraham, Jaroslaw W. Zmijewski Mar 2013

Faculty Publications

Effective removal of apoptotic cells, particularly apoptotic neutrophils, is essential for the successful resolution of acute inflammatory conditions. In these experiments, we found that whereas interaction between vitronectin and integrins diminished the ability of macrophages to ingest apoptotic cells, interaction between vitronectin with urokinase-type plasminogen activator receptor (uPAR) on the surface of apoptotic cells also had equally important inhibitory effects on efferocytosis. Preincubation of vitronectin with plasminogen activator inhibitor-1 eliminated its ability to inhibit phagocytosis of apoptotic cells. Similarly, incubation of apoptotic cells with soluble uPAR or Abs to uPAR significantly diminished efferocytosis. In the setting of LPSinduced ALI, enhanced …


The Transcriptional Regulator Tamr From Streptomyces Coelicolor Controls A Key Step In Central Metabolism During Oxidative Stress, Hao Huang, Anne Grove Mar 2013

The Transcriptional Regulator Tamr From Streptomyces Coelicolor Controls A Key Step In Central Metabolism During Oxidative Stress, Hao Huang, Anne Grove

Faculty Publications

Summary: Multiple antibiotic resistance regulator (MarR) family transcriptional regulators usually regulate gene activity by responding to specific ligands. Here we show that TamR (trans-aconitate methyltransferase regulator), a MarR homologue from Streptomyces coelicolor, functions in oxidative stress responses to regulate a key step in central metabolism. The gene encoding TamR is oriented divergently from the tam gene, which encodes trans-aconitate methyltransferase. Trans-aconitate methyltransferase methylates trans-aconitate, which is formed when cis-aconitate is released during aconitase-mediated isomerization of citrate to isocitrate; trans-aconitate, but not its methyl ester, is a potent inhibitor of aconitase. We show that TamR binds with high affinity to the …

Faculty Publications

The semi-aquatic weevil Bagous hydrillae was released during 1991-1996 at 19 sites in 4 states in attempts to control the aquatic weed hydrilla, Hydrilla verticillata. Fourteen of the sites were in Florida, 2 each in Texas and Georgia and one site in Alabama. Over 320,000 adult weevils were included in these releases. Despite the fact that a few adults were recovered as late as 4.5 yr post-release, presence of permanent, self-perpetuating populations was never confirmed. Then, during 2009 adult B. hydrillae were collected in southern Louisiana, at least 580 km from the nearest release site and 13 yr after attempts …


Biological Control Of Common Salvinia (Salvinia Minima) In Louisiana Using Cyrtobagous Salviniae (Coleoptera: Curculionidae), Katherine A. Parys, Seth J. Johnson Mar 2013

Biological Control Of Common Salvinia (Salvinia Minima) In Louisiana Using Cyrtobagous Salviniae (Coleoptera: Curculionidae), Katherine A. Parys, Seth J. Johnson

Faculty Publications

Common salvinia, Salvinia minima Baker, is an aquatic invasive fern that obstructs waterways and impacts water quality throughout the southeastern United States. In an effort to establish populations for classical biological control of this weed, the weevil, Cyrtobagous salviniae Calder and Sands, was released at multiple sites across Louisiana. Many of the release sites were lost due to a variety of ecological and anthropological disturbances. In 2008, C. salviniae was found to have successfully overwintered on S. minima in Gramercy, Louisiana. Attack by Cyrtobagous salviniae significantly increased the number of damaged terminal buds and decreased the fresh weight biomass of …

Oxidized Amino Acid Residues In The Vicinity Of QA And PheoD1 Of The Photosystem Ii Reaction Center: Putative Generation Sites Of Reducing-Side Reactive Oxygen Species, Laurie K. Frankel, Larry Sallans, Patrick A. Limbach, Terry M. Bricker

Faculty Publications

Under a variety of stress conditions, Photosystem II produces reactive oxygen species on both the reducing and oxidizing sides of the photosystem. A number of different sites including the Mn4O5Ca cluster, P680, PheoD1, QA, QB and cytochrome b559 have been hypothesized to produce reactive oxygen species in the photosystem. In this communication using Fourier-transform ion cyclotron resonance mass spectrometry we have identified several residues on the D1 and D2 proteins from spinach which are oxidatively modified and in close proximity to QA (D1 residues 239F, 241Q, 242E and the D2 residues 238P, 239T, 242E and 247M) and PheoD1 (D1 residues …

Background: Cyanobacteria use multiple PSII-D1 isoforms to adapt to environmental conditions. Results: D1:2 achieves higher quantum efficiency of water oxidation and biomass accumulation rate at high light versus D1:1; the latter is more efficient at low light due to less charge recombination. Conclusion: A functional advantage for D1:1 is revealed for the first time. Significance: Improved photochemical efficiency at low light suggests an evolutionary advantage to retain D1:1. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.

Pediatric patients who received radiation therapy are at risk of developing side effects such as radiogenic second cancer. We compared proton and photon therapies in terms of the predicted risk of second cancers for a 4 year old medulloblastoma patient receiving craniospinal irradiation (CSI). Two CSI treatment plans with 23.4 Gy or Gy (RBE) prescribed dose were computed: a three-field 6 MV photon therapy plan and a four-field proton therapy plan. The primary doses for both plans were determined using a commercial treatment planning system. Stray radiation doses for proton therapy were determined from Monte Carlo simulations, and stray radiation …

Faculty Publications

Impaired insulin signaling is a key feature of type 2 diabetes and is associated with increased ubiquitin-proteasome-dependent protein degradation in skeletal muscle. An extract of Artemisia dracunculus L. (termed PMI5011) improves insulin action by increasing insulin signaling in skeletal muscle. We sought to determine if the effect of PMI5011 on insulin signaling extends to regulation of the ubiquitin-proteasome system. C2C12 myotubes and the KK-Ay murine model of type 2 diabetes were used to evaluate the effect of PMI5011 on steady-state levels of ubiquitylation, proteasome activity and expression of Atrogin-1 and MuRF-1, muscle-specific ubiquitin ligases that are upregulated with impaired insulin …

Variation In Sodium Current Amplitude Between Vasopressin And Oxytocin Hypothalamic Supraoptic Neurons, Reese Scroggs, Lie Wang, Ryoichi Teruyama, William E. Armstrong

Faculty Publications

Biophysical characteristics of tetrodotoxin-sensitive sodium (Na+) currents were studied in vasopressin (VP) and oxytocin (OT) supraoptic neurons acutely isolated from rat hypothalamus. Na+ current density (pA/pF) was significantly greater in VP neurons than in OT neurons. No significant difference between VP and OT neurons was detected regarding the voltage dependence of activation and steady-state inactivation, or rate of recovery from inactivation of Na+ currents. In both VP and OT neurons, the macroscopic inactivation of the Na+ currents was best fitted with a double-exponential expression suggesting two rates of inactivation. Also in both types, the time course of recovery from inactivation …

Standardized Treatment Planning Methodology For Passively Scattered Proton Craniospinal Irradiation, Annelise Giebeler, Wayne D. Newhauser, Richard A. Amos, Anita Mahajan, Kenneth Homann, Rebecca M. Howell

Faculty Publications

Background: As the number of proton therapy centers increases, so does the need for studies which compare proton treatments between institutions and with photon therapy. However, results of such studies are highly dependent on target volume definition and treatment planning techniques. Thus, standardized methods of treatment planning are needed, particularly for proton treatment planning, in which special consideration is paid to the depth and sharp distal fall-off of the proton distribution. This study presents and evaluates a standardized method of proton treatment planning for craniospinal irradiation (CSI).Methods: We applied our institution's planning methodology for proton CSI, at the time of …

Environmentally persistent free radicals (EPFRs) in combustion generated particulate matter (PM) are capable of inducing pulmonary pathologies and contributing to the development of environmental asthma. In vivo exposure of infant rats to EPFRs demonstrates their ability to induce airway hyperresponsiveness to methacholine, a hallmark of asthma. However, the mechanisms by which combustion-derived EPFRs elicit in vivo responses remain elusive. In this study, we used a chemically defined EPFR consisting of approximately 0.2 μm amorphrous silica containing 3% cupric oxide with the organic pollutant 1,2-dichlorobenzene (DCB-230). DCB-230 possesses similar radical content to urban-collected EPFRs but offers several advantages, including lack of …

Social Opportunity Causes Rapid Transcriptional Changes In The Social Behaviour Network Of The Brain In An African Cichlid Fish, K. P. Maruska, A. Zhang, A. Neboori, R. D. Fernald

Faculty Publications

Animals constantly integrate external stimuli with their own internal physiological state to make appropriate behavioural decisions. Little is known, however, about where in the brain the salience of these signals is evaluated, or which neural and transcriptional mechanisms link this integration to adaptive behaviours. We used an African cichlid fish Astatotilapia burtoni to test the hypothesis that a new social opportunity activates the conserved 'social behaviour network' (SBN), a collection of brain nuclei known to regulate social behaviours across vertebrates. We measured mRNA levels of immediate early genes (IEGs) in microdissected brain regions as a proxy for neuronal activation, and …

Message from President: Years ago, American Airlines backgrounded its television advertisements with a hauntingly optimistic jingle featuring one phrase, “something special in the air.” Tone, whether musical or inflectional or atmospheric, is indeed something airy— something halfway between the inferred and the empirical. One of the wonders if not miracles of recent educational policy is the sudden change in tone among the campuses of the University of Louisiana System since the arrival of new, imaginative, and energetic leadership in the “UoL” System office. Nothing has changed in the budget picture and therefore not too much has happened empirically. Nevertheless, and …

Faculty Publications

Effects of treatment of rice seeds with an anthranilic diamide, chlorantraniliprole, and a neonicotinoid, thiamethoxam, on egg laying and first instar survival in rice water weevil, Lissorhoptrus oryzophilus Kuschel, were examined under greenhouse conditions. Exposure of adult weevils to rice (6-7 leaf stage) grown from seeds treated with chlorantraniliprole and thiamethoxam resulted in reduction in numbers of eggs and first instars. The low egg numbers by adults exposed to chlorantraniliprole-treated plants was confirmed as a sublethal effect on adults: adult survival was not impacted after 4 d of feeding on foliage from chlorantraniliprole-treated plants but the number of eggs laid …
