Laboratory Host Range Assessment Of A Predatory Pentatomid, Podisus Maculiventris (Hemiptera: Pentatomidae) For Field Release On Guam, Gadi V.P. Reddy, Rosalie Kikuchi

Faculty Publications

Predation by Podisus maculiventris (Say) (Hemiptera: Pentatomidae) was evaluated with Erionota thrax (L.) (Lepidoptera: Hesperidae), Pericyma cruegeri (Butler) (Lepidoptera: Noctuidae), Pareuchaetes pseudoinsulata Rego Barros (Lepidoptera: Arctiidae), Papilio polytes (L.) (Lepidoptera: Papilionidae) and Eudocima phalonia (L.) comb. nov. (Lepidoptera: Noctuidae). Both free-choice and no-choice experiments indicated that the P. maculiventris attacked and consumed all the larvae of the 5 species included in the tests. Although the larvae died at different intervals, most of them were dead within 24120 h of the introduction of the predatory species. Since the P. maculiventris is polyphagous in nature and the present findings indicate that these …

The objectives were to (1) estimate acute toxicity of cryoprotectants, (2) evaluate vitrification solutions, (3) compare different thawing methods, (4) evaluate membrane integrity of post-thaw sperm vitrified in different cryoprotectants, and (5) evaluate the fertility of vitrified sperm. Nine cryoprotectants and two commercial vitrification additives were tested for acute toxicity and glass forming ability, alone and in combination. Two vitrification …

A Review Of The Toxicity Of Chemical Dispersants, James Wise, John Pierce Wise

Faculty Publications

Chemical dispersants are a mixture of various surfactants and solvents. Most dispersants are proprietary, and the complete composition is not often public knowledge. Chemical dispersants used for the cleanup and containment of crude oil toxicity became a major concern after the 2010 Deepwater Horizon oil crisis in the Gulf of Mexico. During the crisis, millions of liters of chemical dispersants (Corexit 9527 and 9500) were used - the largest known application of dispersants in the field. As of February 2011, 38 peer-reviewed articles were available on the toxicity of 35 different chemical dispersants. Nalco, BP, Shell, and Total Special Fluids …

Associations Between Physical Activity And Submaximal Cardiorespiratory And Pulmonary Responses In Men, John C. Sieverdes, Xuemei Sui, Steven N. Blair

Faculty Publications

Background: Habitual physical activity (PA) is associated with higher cardiorespiratory fitness values, but additional information is needed on the contributions of specific types and amounts of PA. Therefore the main aim of this study was to analyze the heart and lung function of a large cohort of men and compare these outcomes with various modes and volumes of PA.

Methods: We used data from 30,594 men from the Aerobics Center Longitudinal Study who were categorized into sedentary, swimmer, walker, and runner groups using self-report PA data collected during 1970-2005. Additional PA categories using MET-minutes/week were used to group men into …

Radical-Containing Particles Activate Dendritic Cells And Enhance Th17 Inflammation In A Mouse Model Of Asthma, Pingli Wang, Paul Thevenot, Jordy Saravia, Terry Ahlert, Stephania A. Cormier

Faculty Publications

We identified a previously unrecognized component of airborne particulate matter (PM) formed in combustion and thermal processes, namely, environmentally persistent free radicals (EPFRs). The pulmonary health effects of EPFRs are currently unknown. In the present study, we used a model EPFR-containing pollutant-particle system referred to as MCP230. We evaluated the effects of MCP230 on the phenotype and function of bone marrow - derived dendritic cells (BMDCs) in vitro and lung dendritic cells (DCs) in vivo, and the subsequent T-cell response. We also investigated the adjuvant role of MCP230 on airway inflammation in a mouse model of asthma. MCP230 decreased intracellular …

Elimination Of The Nlrp3-Asc Inflammasome Protects Against Chronic Obesity-Induced Pancreatic Damage, Yun Hee Youm, Ayinuer Adijiang, Bolormaa Vandanmagsar, David Burk, Anthony Ravussin, Vishwa Deep Dixit

Faculty Publications

Clinical evidence that the blockade of IL-1β in type-2 diabetic patients improves glycemia is indicative of an autoinflammatory mechanism that may trigger adiposity-driven pancreatic damage. IL-1β is a key contributor to the obesity-induced inflammation and subsequent insulin resistance, pancreatic β-cell dysfunction, and the onset of type 2 diabetes. Our previous studies demonstrated that the ceramides activate the Nod-like receptor family, pyrin domain containing 3 (Nlrp3) inflammasome to cause the generation of mature IL-1β and ablation of the Nlrp3 inflammasome in diet-induced obesity improves insulin signaling. However, it remains unclear whether the post-translational processing of active IL-1β in pancreas is regulated …

Adipose Tissue Endocannabinoid System Gene Expression: Depot Differences And Effects Of Diet And Exercise, Tongjian You, Beth L. Disanzo, Xuewen Wang, Rongze Yang, Dawei Gong

Faculty Publications

Background: Alterations of endocannabinoid system in adipose tissue play an important role in lipid regulation and metabolic dysfunction associated with obesity. The purpose of this study was to determine whether gene expression levels of cannabinoid type 1 receptor (CB1) and fatty acid amide hydrolase (FAAH) are different in subcutaneous abdominal and gluteal adipose tissue, and whether hypocaloric diet and aerobic exercise influence subcutaneous adipose tissue CB1 and FAAH gene expression in obese women.

Methods: Thirty overweight or obese, middle-aged women (BMI = 34.3 ± 0.8 kg/m², age = 59 ± 1 years) underwent one of three 20-week weight …

Modeling Nitrogen Loading In A Small Watershed In Southwest China Using A Dndc Model With Hydrological Enhancements, Jia Deng, Zaixing Zhou, Bo Zhu, Xunhua Zheng, Changsheng Li, X. Wang, Z. Jian

Faculty Publications

The degradation of water quality has been observed worldwide, and inputs of nitrogen (N), along with other nutrients, play a key role in the process of contamination. The quantification of N loading from non-point sources at a watershed scale has long been a challenge. Process-based models have been developed to address this problem. Because N loading from non-point sources result from interactions between biogeochemical and hydrological processes, a model framework must include both types of processes if it is to be useful. This paper reports the results of a study in which we integrated two fundamental hydrologic features, the SCS …

Rapid Expansion Of Oceanic Anoxia Immediately Before The End-Permian Mass Extinction, Gregory A. Brennecka, Achim D. Herrmann, Thomas J. Algeo, Ariel D. Anbar

Faculty Publications

Periods of oceanic anoxia have had a major influence on the evolutionary history of Earth and are often contemporaneous with mass extinction events. Changes in global (as opposed to local) redox conditions can be potentially evaluated using U system proxies. The intensity and timing of oceanic redox changes associated with the end-Permian extinction horizon (EH) were assessed from variations in 238U/ 235U δ 238U) and Th/U ratios in a carbonate section at Dawen in southern China. The EH is characterized by shifts toward lower δ 238U values (from -0.37‰ to -0.65‰), indicative of an expansion of oceanic anoxia, and higher …

Carne Viva In Postville: Stories Of Madres And Monarchs, Jennifer Cooley, Karen Mitchell

Faculty Publications

Carne viva are two words in Spanish that together can be translated various ways. Taken literally, they refer to live flesh, like an open wound. In this way they can allude to the slow process of recovery after a traumatic event. The words draw up images of enduring pain. In addition, they can be read to refer to fresh meat and in the context of human relations, to the image of a new conquest. They can also draw our thoughts to the context of a slaughterhouse, where working conditions involve constant contact with carcasses and blood, and the value of …

Mutations in rumi result in a temperature-sensitive loss of Notch signaling in Drosophila. Drosophila Rumi is a soluble, endoplasmic reticulum-retained protein with a CAP10 domain that functions as a protein O-glucosyltransferase. In human and mouse genomes, three potential Rumi homologues exist: one with a high degree of identity to Drosophila Rumi (52%), and two others with lower degrees of identity but including a CAP10 domain (KDELC1 and KDELC2). Here we show that both mouse and human Rumi, but not KDELC1 or KDELC2, catalyze transfer of glucose from UDPglucose to an EGF repeat from human factor VII. Similarly, human Rumi, but …

Of Stars And Sea Monsters: Creation Theology In The Whirlwind Speeches, Kathryn M. Schifferdecker

Faculty Publications

The whirlwind speeches at the end of Job (Job 38–41) depict a cosmos that is radically non-anthropocentric. This cosmos includes creatures and places indifferent towards human beings and quite dangerous for them. Nevertheless, God delights in these wild creatures and places and gives them a place in creation. Job responds to the whirlwind speeches by choosing to live with the same freedom God grants all of God’s creatures.

Dietary-Resistant Starch Improves Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen, Michael J. Keenan, Anne Raggio, Cathy Williams, Roy J. Martin

Faculty Publications

Scope: Dietary prebiotics show potential in anti-diabetes. Dietary resistant starch (RS) has a favorable impact on gut hormone profiles, including glucagon-like peptide-1 (GLP-1) consistently released, a potent anti-diabetic incretin. Also RS reduced body fat and improved glucose tolerance in rats and mice. In the current project, we hypothesize that dietary-resistant starch can improve insulin sensitivity and pancreatic β cell mass in a type 2 diabetic rat model. Altered gut fermentation and microbiota are the initial mechanisms, and enhancement in serum GLP-1 is the secondary mechanism. Methods and results: In this study, GK rats were fed an RS diet with 30% …

This article takes up the curious tale as to why the text and drafting record in the House and Senate were ignored by the Court in Everson, as well as what the text and debate can tell us about contemporary theories making the rounds. One theory of conservatives is that the Establishment Clause was not intended to prohibit support for religion so long as no religion is preferred.

Pparγ-Independent Increase In Glucose Uptake And Adiponectin Abundance In Fat Cells, Olga Dubuisson, Emily J. Dhurandhar, Rashmi Krishnapuram, Heather Kirk-Ballard, Alok K. Gupta, Vijay Hegde, Elizabeth Floyd, Jeffrey M. Gimble, Nikhil V. Dhurandhar

Faculty Publications

Although thiazolidinediones (TZD) effectively improve hyperglycemia and increase adiponectin, a proinsulin-sensitizing adipokine, they also increase adipogenesis via peroxisome proliferator-activated receptor (PPAR)γ induction, which may be undesirable. Recent safety concerns about some TZD have prompted the search for next generation agents that can enhance glycemic control and adiponectin independent of PPARγ or adipogenesis. Reminiscent of TZD action, a human adenovirus, adenovirus 36 (Ad36), up-regulates PPARγ, induces adipogenesis, and improves systemic glycemic control in vivo. We determined whether this effect of Ad36 requires PPARγ and/or adipogenesis. Glucose uptake and relevant cell signaling were determined in mock-infected or human adenoviruses Ad36 or Ad2-infected …

Food Insecurity And Sexual Risk In An Hiv Endemic Community In Uganda, Cari L. Miller, David R. Bangsberg, David M. Tuller, Jude Senkungu, Annet Kawuma, Edward A. Frongillo Jr., Sheri D. Weiser

Faculty Publications

Food insecurity has been linked to high-risk sexual behavior in sub-Saharan Africa, but there are limited data on these links among people living with HIV/AIDS, and on the mechanisms for how food insecurity predisposes individuals to risky sexual practices. We undertook a series of in-depth open-ended interviews with 41 individuals living with HIV/AIDS to understand the impact of food insecurity on sexual-risk behaviors. Participants were recruited from the Immune Suppression Clinic at the Mbarara University of Science and Technology in Mbarara, Uganda. Interviews were recorded, transcribed verbatim, translated, and coded following the strategy of grounded theory. Four major themes emerged …

Engaging The Legal Academy In Disaster Response, Susan Kuo, Davida Finger, Laila Hlass, Anne Hornsby, Rachel Van Cleave

Faculty Publications

This article discusses three models of law school engagement that have been used to respond to natural disasters. The three models discussed are a disaster law clinic, a course on disaster law, and a student-led initiative featuring non-credit, pro bono placements. Each model offers a conceptual approach for integrating community-based, justice-oriented initiatives into academic and clinical teaching. Taken as templates for a more permanent model of engagement in the area of post-disaster law and social justice, these models demonstrate that the legal academy can meet its service obligation to the community while training lawyers to better appreciate the central tenets …

The Deepwater Horizon (DWH) well blowout released more petroleum hydrocarbons into the marine environment than any previous U.S. oil spill (4.9 million barrels), fouling marine life, damaging deep sea and shoreline habitats and causing closures of economically valuable fisheries in the Gulf of Mexico. A suite of pollutants—liquid and gaseous petroleum compounds plus chemical dispersants—poured into ecosystems that had already been stressed by overfishing, development and global climate change. Beyond the direct effects that were captured in dramatic photographs of oiled birds in the media, it is likely that there are subtle, delayed, indirect and potentially synergistic impacts of these …

Aebp2 As An Epigenetic Regulator For Neural Crest Cells, Hana Kim, Keunsoo Kang, Muhammad B. Ekram, Tae Young Roh, Joomyeong Kim

Faculty Publications

Aebp2 is a potential targeting protein for the mammalian Polycomb Repression Complex 2 (PRC2). We generated a mutant mouse line disrupting the transcription of Aebp2 to investigate its in vivo roles. Aebp2-mutant homozygotes were embryonic lethal while heterozygotes survived to adulthood with fertility. In developing mouse embryos, Aebp2 is expressed mainly within cells of neural crest origin. In addition, many heterozygotes display a set of phenotypes, enlarged colon and hypopigmentation, similar to those observed in human patients with Hirschsprung's disease and Waardenburg syndrome. These phenotypes are usually caused by the absence of the neural crest-derived ganglia in hindguts and melanocytes. …

The Regulation Of Skeletal Muscle Protein Turnover During The Progression Of Cancer Cachexia In The ApcMin/+ Mouse, James P. White, John W. Baynes, Stephen L. Welle, Matthew C. Kostek, Lydia E. Matesic, Shuichi Sato, James A. Carson

Faculty Publications

Muscle wasting that occurs with cancer cachexia is caused by an imbalance in the rates of muscle protein synthesis and degradation. The Apc(Min/+) mouse is a model of colorectal cancer that develops cachexia that is dependent on circulating IL-6. However, the IL-6 regulation of muscle protein turnover during the initiation and progression of cachexia in the Apc(Min/+) mouse is not known. Cachexia progression was studied in Apc(Min/+) mice that were either weight stable (WS) or had initial (≤5%), intermediate (6-19%), or extreme (≥20%) body weight loss. The initiation of cachexia reduced %MPS 19% and a further ∼50% with additional weight …

Tax Neutrality And Tax Amenities, David M. Hasen

Faculty Publications

Neutrality has been a dominant theme in scholarly and policy debates on international taxation for fifty years. This paper questions whether the concept of tax neutrality is adequately specified for analyzing the efficiency properties of international tax systems. As distinct from the closed economy setting, in the open economy setting, tax incentive effects include the redirection of both capital and tax revenues from one jurisdiction to another. Because tax revenues finance infrastructure and other productivity-enhancing goods – so-called “tax amenities” – and because capital burdens infrastructure, one consequence of the reallocation of tax revenues and assets is the adjustment of …

Enhancing Arabidopsis Leaf Growth By Engineering The Brassinosteroid Insensitive1 Receptor Kinase, Man Ho Oh, Jindong Sun, Dong Ha Oh, Raymond E. Zielinski, Steven D. Clouse, Steven C. Huber

Faculty Publications

The BRASSINOSTEROID INSENSITIVE1 (BRI1) receptor kinase has recently been shown to possess tyrosine kinase activity, and preventing autophosphorylation of the tyrosine-831 regulatory site by site-directed mutagenesis enhances shoot growth. In this study, we characterized the increased leaf growth of Arabidopsis (Arabidopsis thaliana) plants expressing BRI1(Y831F)-Flag compared with BRI1-Flag (both driven by the native promoter and expressed in the bri1-5 weak allele background) and provide insights into the possible mechanisms involved. On average, relative leaf growth rate was increased 16% in the Y831F plants (in the bri1-5 background), and the gain of function of the Y831F-directed mutant was dominant in the …

Stat5a Expression In Swiss 3t3 Cells Promotes Adipogenesis In Vivo In An Athymic Mice Model System, William C. Stewart, Lisa A. Pearcy, Z. Elizabeth Floyd, Jacqueline M. Stephens

Faculty Publications

Many studies from our laboratories and others have shown that STAT5 expression and activity are increased during adipogenesis of murine and human adipocytes. Ectopic expression of STAT5A in fibroblasts or preadipocytes can confer or enhance adipogenesis. To determine whether STAT5A also plays a role in adipogenesis in vivo, we injected athymic mice with Swiss 3T3 cells expressing an empty pBABE retrovirus, Swiss cells expressing a pBABE retrovirus-containing STAT5A, or 3T3-F442A preadipocytes. Athymic mice injected with either 3T3-F442A cells or Swiss 3T3 cells expressing STAT5A resulted in fat pad formation at the site of injection. However, mice injected with Swiss cells …

Brazilian peppertree, Schinus terebinthifolius Raddi, is a perennial woody plant native to Brazil, Argentina, and Paraguay that is recognized as one of the most invasive weeds in Florida. A new species of leaflet galling psyllid was discovered attacking Brazilian peppertree in Bahia, Brazil in March 2010. In this paper, a formal morphological description of the new psyllid Calophya latiforceps sp. nov. (Hemiptera: Calophyidae) is presented along with molecular evidence confirming new species designation. This previously unknown natural enemy may have potential as a biological control agent for the Brazilian peppertree. Copyright © 2011 BioOne All rights reserved.

Faculty Publications

Receptors localized at the plasma membrane are critical for the recognition of pathogens. The molecular determinants that regulate receptor transport to the plasma membrane are poorly understood. In a screen for proteins that interact with the FLAGELIN-SENSITIVE2 (FLS2) receptor using Arabidopsis thaliana protein microarrays, we identified the reticulon-like protein RTNLB1. We showed that FLS2 interacts in vivo with both RTNLB1 and its homolog RTNLB2 and that a Ser-rich region in the N-terminal tail of RTNLB1 is critical for the interaction with FLS2. Transgenic plants that lack RTNLB1 and RTNLB2 (rtnlb1 rtnlb2) or overexpress RTNLB1 (RTNLB1ox) exhibit reduced activation of FLS2-dependent …
