A Triple Threat: The Parastagonospora Nodorum Sntox267 Effector Exploits Three Distinct Host Genetic Factors To Cause Disease In Wheat, Jonathan K. Richards, Gayan K. Kariyawasam, Sudeshi Seneviratne, Nathan A. Wyatt, Steven S. Xu, Zhaohui Liu, Justin D. Faris, Timothy L. Friesen Jan 2022

A Triple Threat: The Parastagonospora Nodorum Sntox267 Effector Exploits Three Distinct Host Genetic Factors To Cause Disease In Wheat, Jonathan K. Richards, Gayan K. Kariyawasam, Sudeshi Seneviratne, Nathan A. Wyatt, Steven S. Xu, Zhaohui Liu, Justin D. Faris, Timothy L. Friesen

Faculty Publications

Parastagonospora nodorum is a fungal pathogen of wheat. As a necrotrophic specialist, it deploys effector proteins that target dominant host susceptibility genes to elicit programmed cell death (PCD). Here we identify and functionally validate the effector targeting the host susceptibility genes Snn2, Snn6 and Snn7. We utilized whole-genome sequencing, association mapping, gene-disrupted mutants, gain-of-function transformants, virulence assays, bioinformatics and quantitative PCR to characterize these interactions. A single proteinaceous effector, SnTox267, targeted Snn2, Snn6 and Snn7 to trigger PCD. Snn2 and Snn6 functioned cooperatively to trigger PCD in a light-dependent pathway, whereas Snn7-mediated PCD functioned in a light-independent pathway. Isolates harboring …

A Longitudinal Investigation Of The Semantic Receptive-Expressive Gap In Spanish-English Bilingual Children, Todd A. Gibson, Elizabeth D. Peña, Lisa M. Bedore, Kevin S. Mccarter

Faculty Publications

Although a semantic receptive-expressive gap appears to be a universal feature of early bilingualism, little is known about its development. We sought to determine if the magnitude of the discrepancy between receptive and expressive standard scores changed over time in bilingual children’s two languages. In this longitudinal study, standardized receptive and expressive semantics tests of 106 Spanish-English bilingual children with TD were taken at kindergarten and first grade in both English and Spanish. We used a multivariate analysis approach to identify interactions and main effects. Although both receptive and expressive standard scores improved across the year in both languages, the …

Price Response Of The High Fructose Corn Syrup Industry In The United States: A Bertrand Model Application, Pablo A. Garcia-Fuentes, P. Lynn Kennedy, Gustavo F.C. Ferreira Jan 2022

Price Response Of The High Fructose Corn Syrup Industry In The United States: A Bertrand Model Application, Pablo A. Garcia-Fuentes, P. Lynn Kennedy, Gustavo F.C. Ferreira

Faculty Publications

This paper uses a Bertrand duopoly model application and derives a high fructose corn syrup (HFCS) price reaction function that shows the response of the price of HFCS to changes in the price of sugar. It conducts cointegration analysis and assesses the performance of the HFCS price reaction model by estimating a Dynamic Ordinary Least-Squares model. It finds that the prices of HFCS-55, sugar, and corn are cointegrated over the period 1981:1 to 2017:12. The estimated long-run relationship shows that a one percent increase in the price of sugar increases the price of HFCS-55 by 0.19 percent. Additionally, the price …

Alternative Nesting Strategies Of Polistine Wasps In A Subtropical Locale, Scott Nacko, Mark A. Hall, Gregg Henderson Jan 2022

Alternative Nesting Strategies Of Polistine Wasps In A Subtropical Locale, Scott Nacko, Mark A. Hall, Gregg Henderson

Faculty Publications

Phylogenetic studies suggest that historically all paper wasps (Vespidae: Polistinae) in North America have tropical origins, but some species have adapted to survive temperate conditions. Subtropical climates, which are intermediate between temperate and tropical, allow a unique opportu-nity to study ancestral traits which can be retained or lost within populations, and ultimately elucidate the process of social wasp evolution. We investigated the phenology of paper wasps at study sites in subtropical Baton Rouge, USA, through nest searching and monitoring of nest parameters throughout the warm season (March–October). Across the year, two periods of nest initiation occurred: from March–May (early season …

Inference On Moderation Effect With Third-Variable Effect Analysis–Application To Explore The Trend Of Racial Disparity In Oncotype Dx Test For Breast Cancer Treatment, Qingzhao Yu, Lu Zhang, Xiaocheng Wu, Bin Li

Faculty Publications

Third variable effect refers to the effect from a third variable that explains an observed relationship between an exposure and an outcome. Depending on whether there is causal relationship, typically, a third variable takes the format of a mediator or a confounder. A moderation effect is a special case of the third-variable effect, where the moderator and other variables have an interactive effect on the outcome. In this paper, we extend the R package ‘mma’ for moderation analysis so that third-variable effects can be reported at different levels of the moderator. The proposed moderation analysis use tree-structured models to automatically …

Racial Discrimination And Hazardous Drinking Among Black Drinkers: The Role Of Social Anxiety In The Minority Stress Model, Julia D. Buckner, Nina I. Glover, Justin M. Shepherd, Michael J. Zvolensky Jan 2022

Racial Discrimination And Hazardous Drinking Among Black Drinkers: The Role Of Social Anxiety In The Minority Stress Model, Julia D. Buckner, Nina I. Glover, Justin M. Shepherd, Michael J. Zvolensky

Faculty Publications

Objective: Black Americans who consume alcohol experience worse alcohol-related outcomes. Thus, identifying psycho-sociocultural factors that play a role in hazardous drinking among Black individuals is vital to informing prevention and treatment efforts to reduce these disparities. Racial discrimination is related to hazardous drinking among Black adults, suggesting that some may drink (and continue to drink despite drinking-related problems) to alleviate negative affect (e.g., depression, anxiety) associated with discrimination. Yet, despite the social nature of both racial discrimination and drinking, no known research has examined the role of social anxiety in the relations among racial discrimination experiences and hazardous drinking. Method: …

Estrogen receptor–α (ERα) expressed by neurons in the ventrolateral subdivision of the ventromedial hypothalamic nucleus (ERαvlVMH) regulates body weight in females, but the downstream neural circuits mediating this biology remain largely unknown. Here we identified a neural circuit mediating the metabolic effects of ERαvlVMH neurons. We found that selective activation of ERαvlVMH neurons stimulated brown adipose tissue (BAT) thermogenesis, physical activity, and core temperature and that ERαvlVMH neurons provide monosynaptic glutamatergic inputs to 5-hydroxytryptamine (5-HT) neurons in the dorsal raphe nucleus (DRN). Notably, the ERαvlVMH → DRN circuit responds to changes in ambient temperature and nutritional states. We further showed …

Tropical leaf phenology—particularly its variability at the tree-crown scale—dominates the seasonality of carbon and water fluxes. However, given enormous species diversity, accurate means of monitoring leaf phenology in tropical forests is still lacking. Time series of the Green Chromatic Coordinate (GCC) metric derived from tower-based red–greenblue (RGB) phenocams have been widely used to monitor leaf phenology in temperate forests, but its application in the tropics remains problematic. To improve monitoring of tropical phenology, we explored the use of a deep learning model (i.e. superpixel-based Residual Networks 50, SP-ResNet50) to automatically differentiate leaves from non-leaves in phenocam images and to derive …

Rates of suicide in the US Army continue to rise, and by some accounts exceed the general population. This increase has renewed efforts to identify protective factors that may inform novel suicide prevention strategies. Previous research has demonstrated that a sense of purpose in life and perceived cohesion with military peers are related to a reduction in the severity of suicidal ideation (SI). Additionally, research in military samples supports decreased SI in Soldiers who endorse that their leaders convey a sense of purpose and meaning in their shared mission. However, no work has investigated whether these leadership styles relate to …

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum Jan 2022

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum

Division of Basic Science Faculty Publications

Adverse exposures during pregnancy have been shown to contribute to susceptibility for chronic diseases in offspring. Maternal diabetes during pregnancy is associated with higher risk of pregnancy complications, structural birth defects, and cardiometabolic health impairments later in life. We showed previously in a mouse model that the placenta is smaller in diabetic pregnancies, with reduced size of the junctional zone and labyrinth. In addition, cell migration is impaired, resulting in ectopic accumulation of spongiotrophoblasts within the labyrinth. The present study had the goal to identify the mechanisms underlying the growth defects and trophoblast migration abnormalities. Based upon gene expression assays …

Insulin Resistance Persists Despite A Metabolically Healthy Obesity Phenotype, Kristin K. Hoddy, Christopher L. Axelrod, Jacob T. Mey, Adithya Hari, Robbie A. Beyl, Jourdan B. Blair, Wagner S. Dantas, John P. Kirwan Jan 2022

Insulin Resistance Persists Despite A Metabolically Healthy Obesity Phenotype, Kristin K. Hoddy, Christopher L. Axelrod, Jacob T. Mey, Adithya Hari, Robbie A. Beyl, Jourdan B. Blair, Wagner S. Dantas, John P. Kirwan

Division of Basic Science Faculty Publications

Objective: Metabolically healthy obesity (MHO) is often defined as the absence of metabolic syndrome in the presence of obesity. However, phenotypic features of MHO are unclear. Insulin sensitivity in MHO was cross-sectionally compared with metabolically unhealthy obesity (MUO) and a reference group of young healthy participants without obesity. Methods: Sedentary adults (n = 96) undergoing anthropometric, blood chemistries, maximal aerobic capacity, and euglycemic-hyperinsulinemic clamp measurements were classified by BMI (< 25 and ≥30 kg/m2). MUO was defined as having obesity with metabolic syndrome (≥2 additional risk factors). Data were analyzed using a linear mixed models approach. Results: Body weight was similar between MHO and MUO. Body fat (percentage) and high-density lipoprotein cholesterol were higher (p < 0.001), and systolic blood pressure, triglycerides, glucose, and insulin were lower in MHO versus MUO (p < 0.03, all). The MHO group also had lower high-density lipoprotein cholesterol and higher low-density lipoprotein cholesterol, diastolic blood pressure, and insulin compared with the reference. Both the MHO and MUO groups displayed impaired insulin sensitivity compared with the reference control (p < 0.001). Conclusions: Participants with MHO had distinct clinical measures related to hypertension, lipid metabolism, and glycemic control compared with a healthy reference group. Peripheral insulin resistance in obesity independent of metabolic status portends increased risk for type 2 diabetes in the MHO patient population.

Nonlinear Conditional Time-Varying Granger Causality Of Task Fmri Via Deep Stacking Networks And Adaptive Convolutional Kernels, Kai Cheng Chuang, Sreekrishna Ramakrishnapillai, Lydia Bazzano, Owen Carmichael Jan 2022

Nonlinear Conditional Time-Varying Granger Causality Of Task Fmri Via Deep Stacking Networks And Adaptive Convolutional Kernels, Kai Cheng Chuang, Sreekrishna Ramakrishnapillai, Lydia Bazzano, Owen Carmichael

Clinical Research Faculty Publications

Time-varying Granger causality refers to patterns of causal relationships that vary over time between brain functional time series at distinct source and target regions. It provides rich information about the spatiotemporal structure of brain activity that underlies behavior. Current methods for this problem fail to quantify nonlinear relationships in source-target relationships, and require ad hoc setting of relationship time lags. This paper proposes deep stacking networks (DSNs), with adaptive convolutional kernels (ACKs) as component parts, to address these challenges. The DSNs use convolutional neural networks to estimate nonlinear source-target relationships, ACKs allow these relationships to vary over time, and time …

Although Borneo has received more attention from biologists than most other islands in the Malay Ar-chipelago, many questions regarding the systematic relationships of Bornean mammals remain. Using next-generation sequencing technology, we obtained mitochondrial DNA sequences from the holotype of Suncus ater, the only known specimen of this shrew. Several shrews collected recently in Sarawak are closely aligned, both morphologically and mitochondrially, with the holotype of S. ater. Phylogenetic analyses of mitochondrial sequences indicate that the S. ater holotype and new Sarawak specimens do not belong to the genus Suncus, but instead are most closely related to Palawanosorex muscorum. Until now …

Faculty Publications

Behavioral traits such as anxiety and depression have been linked to diversity of the gut microbiome in humans, domesticated animals, and lab-bred model species, but the extent to which this link exists in wild animals, and thus its eco- logical relevance, is poorly understood. We examined the relationship between a behavioral trait (neophobia) and the cloacal microbiome in wild house sparrows ( Passer domesticus, n = 22) to determine whether gut microbial diversity is related to per- sonality in a wild animal. We swabbed the cloaca immediately upon capture, assessed neophobia phenotypes in the lab, and then swabbed the cloaca …

Morphology Of Migration: Associations Between Wing Shape, Bill Morphology And Migration In Kingbirds (Tyrannus), Maggie P. Macpherson, Alex E. Jahn, Nicholas A. Mason

Faculty Publications

Morphology is closely linked to locomotion and diet in animals. In animals that undertake long-distance migrations, limb morphology is under selection to maximize mobility and minimize energy expenditure. Migratory behaviours also interact with diet, such that migratory animals tend to be dietary generalists, whereas sedentary taxa tend to be dietary specialists. Despite a hypothesized link between migration status and morphology, phylogenetic comparative studies have yielded conflicting findings. We tested for evolutionary associations between migratory status and limb and bill morphology across kingbirds, a pan-American genus of birds with migratory, partially migratory and sedentary taxa. Migratory kingbirds had longer wings, in …

Self-assembled supramolecular coordination complexes can take on a wide range of three-dimensional architectures with varying ratios of metal-to-ligand. Control over which architecture will be adopted can be difficult to maintain, as many may form from the starting materials and conditions present. Characterizing the resulting architectures formed can be challenging, in particular when discerning between lower or higher ordered structures of identical stoichiometry. Here we report the synthesis and characterization of a Ti2L3 football-like or pill-shaped capsule, unexpectedly formed from attempts to synthesize variations on a Ti4L6 tetrahedron. The two anionic cores are formed from identical stoichiometric ratios of organic linkers …

Moral Emotions And Unnamed Wrongs: Revisiting Epistemic Injustice, Usha Nathan Jan 2022

Moral Emotions And Unnamed Wrongs: Revisiting Epistemic Injustice, Usha Nathan

Faculty Publications

Current discussions of hermeneutical injustice, I argue, poorly characterise the cognitive state of victims by failing to account for the communicative success that victims have when they describe their experience to other similarly situated persons. I argue that victims, especially when they suffer moral wrongs that are yet unnamed, are able (1) to grasp certain salient aspects of the wrong they experience and (2) to cultivate the ability to identify instances of the wrong in virtue of moral emotions. By moral emotions I mean emotions like indignation that reflect an agent’s ethical commitments and bear on her ethical assessments. Further, …

Background: For many cardiovascular risk factors there is no lower limit to which further reduction will result in decreased disease risk; this includes values within ranges considered normal for healthy adults. This seems to be true for new emerging metabolic risk factors identified by innovative technological advances. Further, there seems to be ever evolving evidence of differential responses to lifestyle interventions by sex and body compositions in the normal range. In this secondary analysis, we had the opportunity to test these principles for newly identified molecular biomarkers of cardiometabolic risk in a young (21–50 years), normal weight healthy population undergoing …

Calcium-Rich Dravite From The Arignac Gypsum Mine, France: Implications For Tourmaline Development In A Sulfate-Rich, Highly Magnesian Meta-Evaporite, Barbara Dutrow, Darrell Henry Jan 2022

Calcium-Rich Dravite From The Arignac Gypsum Mine, France: Implications For Tourmaline Development In A Sulfate-Rich, Highly Magnesian Meta-Evaporite, Barbara Dutrow, Darrell Henry

Faculty Publications

Tourmaline occurs in a wide range of compositional environments, but its occurrence in meta-evaporites is less commonly investigated. Highly magnesian (XMg = 0.90–0.98), poikiloblastic tourmaline occurs in a sulfate-rich, anhydrite– gypsum-bearing meta-evaporite in the Arignac Gypsum Mine, France and preserves a petrologic record of this unusual geochemical environment. Originally a Triassic evaporite deposit, the sample is interpreted to have undergone high-tem-perature–low-pressure (HT–LP) metamorphism and subsequently experienced low-grade, highly deformed overprints. Poikiloblastic tourmaline preserves relicts of the HT–LP mineral assemblage, as inclusions of anhydrite, phlogopite, dolomite, tremolite, Cl-rich scapolite (71–85 % marialite component), rutile, zircon, and fluor-apatite. The low-grade deformational overprints …

We propose an adversarial learning framework that deals with the privacy-utility tradeoff problem under two types of conditions: data-type ignorant, and data-type aware. Under data-type aware conditions, the privacy mechanism provides a one-hot encoding of categorical features, representing exactly one class, while under data-type ignorant conditions the categorical variables are represented by a collection of scores, one for each class. We use a neural network architecture consisting of a generator and a discriminator, where the generator consists of an encoder-decoder pair, and the discriminator consists of an adversary and a utility provider. Unlike previous research considering this kind of architecture, …
