A Conceptual Framework For Analyzing Social-Ecological Models Of Emerging Infectious Diseases, Melissa L. Finucane, Jefferson Fox, Sumeet Saksena, James H. Spencer

Faculty Publications

Unraveling mechanisms that underlie new and reemerging infectious diseases (EID) requires exploring complex interactions within and among coupled natural and human (CNH) systems. This scientifi c problem poses one of the most diffi cult challenges for society today (Wilcox and Colwell 2005 ). EID are diseases that have recently increased in incidence or in geographic or host range (e.g., tuberculosis, cholera, malaria, dengue fever), and diseases caused by new pathogens and new variants assigned to known pathogens (e.g., HIV, SARS, Nipah virus, and avian infl uenza) (Morse 2005 ). Wilcox and Gubler ( 2005 ) and Wilcox and Colwell ( …

Exploring Local Adaptation And The Ocean Acidification Seascape - Studies In The California Current Large Marine Ecosystem, G. E. Hofmann, T. G. Evans, M. W. Kelly, J. L. Padilla-Gamiño, C. A. Blanchette, L. Washburn, F. Chan, M. A. Mcmanus, B. A. Menge, B. Gaylord, T. M. Hill, E. Sanford, M. Lavigne, J. M. Rose, L. Kapsenberg, J. M. Dutton

Faculty Publications

The California Current Large Marine Ecosystem (CCLME), a temperate marine region dominated by episodic upwelling, is predicted to experience rapid environmental change in the future due to ocean acidification. The aragonite saturation state within the California Current System is predicted to decrease in the future with near-permanent undersaturation conditions expected by the year 2050. Thus, the CCLME is a critical region to study due to the rapid rate of environmental change that resident organisms will experience and because of the economic and societal value of this coastal region. Recent efforts by a research consortium-the Ocean Margin Ecosystems Group for Acidification …

Capillary Electrophoresis-Based Assay Of Phosphofructokinase-1, Andrew Malina, Sherrisse K. Bryant, Simon H. Chang, Grover L. Waldrop, S. Douglass Gilman

Faculty Publications

An assay was developed for phosphofructokinase-1 (PFK-1) using capillary electrophoresis (CE). In the glycolytic pathway, this enzyme catalyzes the rate-limiting step from fructose-6-phosphate and magnesium-bound adenosine triphosphate (Mg-ATP) to fructose-1,6-bisphosphate and magnesium-bound adenosine diphosphate (Mg-ADP). This enzyme has recently become a research target because of the importance of glycolysis in cancer and obesity. The CE assay for PFK-1 is based on the separation and detection by ultraviolet (UV) absorbance at 260 nm of Mg-ATP and Mg-ADP. The separation was enhanced by the addition of Mg 2+ to the separation buffer. Inhibition studies of PFK-1 by aurintricarboxylic acid and palmitoyl coenzyme …

Can Crude Oil Toxicity On Phytoplankton Be Predicted Based On Toxicity Data On Benzo(A)Pyrene And Naphthalene?, Koray Ozhan, Sibel Bargu

Faculty Publications

Polycyclic aromatic hydrocarbons (PAHs), which are major components of crude oil, are responsible in large part for the toxicity of crude oil to phytoplankton. This study addressed the following question. Can reliable predictions of the aquatic toxicity of crude oil, a multi-component mixture, be described from toxicity data on individual PAH compounds? Naphthalene, the most abundant PAH compound, and benzo(a)pyrene, a highly toxic PAH compound, were selected as model compounds to quantify toxicity of crude oil on two phytoplankton species, Ditylum brightwellii and Heterocapsa triquetra, by analyzing the effects of different concentrations of these PAHs on growth rate. EC50 values …

Mccutcheon, Anne M. Raggio, Christine Pelkman, Holiday A. Durham, June Zhou, Reshani N. Senevirathne, Cathy Williams, Frank Greenway, John Finley, Zhanguo Gao, Felicia Goldsmith, Michael J. Keenan

Faculty Publications

Objective Obesity is a health concern. Resistant starch (RS) type 2 from high-amylose maize (HAM-RS2) and dietary sodium butyrate (SB) reduce abdominal fat in rodents. RS treatment is associated with increased gut hormones peptide YY (PYY) and glucagon-like peptide 1 (GLP-1), but it is not known if SB increases these hormones. Design and Methods This was investigated in a 2 × 2 rat study with HAM-RS2 (0 or 28% weight) and dietary sodium butyrate (0 and 3.2%) resulting in isocaloric treatments: energy control (EC), sodium butyrate (SB), HAM-RS2 (RS), and the combination (SBRS). Results RS and SB reduced abdominal fat …

Oncostatin M Is Produced In Adipose Tissue And Is Regulated In Conditions Of Obesity And Type 2 Diabetes, David Sanchez-Infantes, Ursula A. White, Carrie M. Elks, Ron F. Morrison, Jeffrey M. Gimble, Robert V. Considine, Anthony W. Ferrante, Eric Ravussin, Jacqueline M. Stephens

Faculty Publications

Context: Adipose tissue is a highly active endocrine organ that secretes many factors that affect other tissues and whole-body metabolism. Adipocytes are responsive to several glycoprotein 130 (gp130) cytokines, some of which have been targeted as potential antiobesity therapeutics. Objective: Oncostatin M (OSM) is a gp130 family member known to inhibit adipocyte differentiation in vitro, but its effects on other adipocyte properties are not characterized. The expression of OSM in white adipose tissue (WAT) has not been evaluated in the context of obesity. Thus, our objective was to examine the expression of adipose tissue OSM in obese animals and humans. …

Virulence And Biotype Analyses Of Hessian Fly (Diptera: Cecidomyiidae) Populations From Texas, Louisiana, And Oklahoma, Sandra Garcés-Carrera, Allen Knutson, Haiyan Wang, Kristopher L. Giles, Fangneng Huang, R. Jeffrey Whitworth, C. Michael Smith, Ming Shun Chen

Faculty Publications

Hessian fly, Mayetiola destructor (Say, 1817), is a major pest of wheat, and is controlled mainly through deploying fly-resistant wheat cultivars. The challenge for the plant resistance approach is that virulence of Hessian fly populations in the field is dynamic, and wheat cultivars may lose resistance within 6 - 8 yr. To ensure continuous success of host plant resistance, Hessian fly populations in the field need to be constantly monitored to determine which resistance genes remain effective in different geographic regions. This study investigated five Hessian fly populations collected from Texas, Louisiana, and Oklahoma, where infestation by Hessian fly has …

Effects Of Biological Control On Long-Term Population Dynamics: Identifying Unexpected Outcomes, James R. Reilly, Bret D. Elderd

Faculty Publications

Attempts to control natural systems through management have often met with success but have also led to unexpected and often undesirable outcomes. Unfortunately, the ultimate result of such management programmes may not be apparent until long after the control efforts have begun. This is particularly true for forest-defoliating species that exhibit long-period cycles such as the invasive gypsy moth Lymantria dispar, which causes widespread damage in some years but is rare in other years. We studied the effects of two commonly employed biocontrol agents on gypsy moth dynamics using a series of field-tested and empirically parameterized mathematical models, which allowed …

Contributions Of Adipose Tissue Architectural And Tensile Properties Toward Defining Healthy And Unhealthy Obesity, Denise E. Lackey, David H. Burk, Mohamed R. Ali, Rouzbeh Mostaedi, William H. Smith, Jiyoung Park, Philipp E. Scherer, Shundra A. Seay, Colin S. Mccoin, Paolo Bonaldo, Sean H. Adams

Faculty Publications

The extracellular matrix (ECM) plays an important role in the maintenance of white adipose tissue (WAT) architecture and function, and proper ECM remodeling is critical to support WAT malleability to accomodate changes in energy storage needs. Obesity and adipocyte hypertrophy place a strain on the ECM remodeling machinery, which may promote disordered ECM and altered tissue integrity and could promote proinflammatory and cell stress signals. To explore these questions, new methods were developed to quantify omental and subcutaneous WAT tensile strength and WAT collagen content by three-dimensional confocal imaging, using collagen VI knockout mice as a methods validation tool. These …

Binding Of Hsv-1 Glycoprotein K (Gk) To Signal Peptide Peptidase (Spp) Is Required For Virus Infectivity, Sariah J. Allen, Kevin R. Mott, Yoshiharu Matsuura, Kohji Moriishi, Konstantin G. Kousoulas, Homayon Ghiasi

Faculty Publications

Glycoprotein K (gK) is a virion envelope protein of herpes simplex virus types 1 (HSV-1) and 2 (HSV-2), which plays important roles in virion entry, morphogenesis and egress. Two-hybrid and pull-down assays were utilized to demonstrate that gK and no other HSV-1 genes specifically binds to signal peptide peptidase (SPP), also known as minor histocompatibility antigen H13. SPP dominant negative mutants, shRNA against SPP significantly reduced HSV-1 replication in vitro. SPP also affected lysosomes and ER responses to HSV-1 infection. Thus, in this study we have shown for the first time that gK, despite its role in fusion and egress, …

Aphid Amino Acid Transporter Regulates Glutamine Supply To Intracellular Bacterial Symbionts, Daniel R.G. Price, Honglin Feng, James D. Baker, Selvan Bavan, Charles W. Luetje, Alex C.C. Wilson

Faculty Publications

Endosymbiotic associations have played a major role in evolution. However, the molecular basis for the biochemical interdependence of these associations remains poorly understood. The aphid-Buchnera endosymbiosis provides a powerful system to elucidate how these symbioses are regulated. In aphids, the supply of essential amino acids depends on an ancient nutritional symbiotic association with the gamma-proteobacterium Buchnera aphidicola. Buchnera cells are densely packed in specialized aphid bacteriocyte cells. Here we confirm that five putative amino acid transporters are highly expressed and/or highly enriched in Acyrthosiphon pisum bacteriocyte tissues. When expressed in Xenopus laevis oocytes, two bacteriocyte amino acid transporters displayed significant …

Species Coexistence And The Dynamics Of Phenotypic Evolution In Adaptive Radiation, Joseph A. Tobias, Charlie K. Cornwallis, Elizabeth P. Derryberry, Santiago Claramunt, Robb T. Brumfield, Nathalie Seddon

Faculty Publications

Interactions between species can promote evolutionary divergence of ecological traits and social signals, a process widely assumed to generate species differences in adaptive radiation. However, an alternative view is that lineages typically interact when relatively old, by which time selection for divergence is weak and potentially exceeded by convergent selection acting on traits mediating interspecific competition. Few studies have tested these contrasting predictions across large radiations, or by controlling for evolutionary time. Thus the role of species interactions in driving broad-scale patterns of trait divergence is unclear. Here we use phylogenetic estimates of divergence times to show that increased trait …

Eutrophication-Driven Deoxygenation In The Coastal Ocean, N N. Rabalais, W J. Cai, J Carstensen, D J. Conley, N N. Rabalais, X P. Hu, Z Quinones-Rivera, R Rosenberg, C P. Slomp, R. Eugene Turner, M Voss, B Wissel, J Zhang

Faculty Publications

Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world's coastal ocean. Climate changes and extreme weather events may modify hypoxia. Organismal and fisheries effects are at the heart of the coastal hypoxia issue, but more subtle regime shifts and trophic interactions are also cause for concern. The chemical milieu associated with declining dissolved oxygen concentrations affects the biogeochemical cycling of oxygen, carbon, nitrogen, phosphorus, silica, trace metals, and sulfide as observed in water column processes, shifts in sediment …
