© 2017, The Author(s). Components of the fibrinolytic system are subjected to stringent control to maintain proper hemostasis. Central to this regulation is the serpin plasminogen activator inhibitor-1 (PAI-1), which is responsible for specific and rapid inhibition of fibrinolytic proteases. Active PAI-1 is inherently unstable and readily converts to a latent, inactive form. The binding of vitronectin and other ligands influences stability of active PAI-1. Our laboratory recently observed reciprocal effects on the stability of active PAI-1 in the presence of transition metals, such as copper, depending on the whether vitronectin was also present (Thompson et al. Protein Sci 20:353–365, …

The Statistical Need To Include Phylogeny In Trait-Based Analyses Of Community Composition, Daijiang Li, Anthony R. Ives Oct 2017

The Statistical Need To Include Phylogeny In Trait-Based Analyses Of Community Composition, Daijiang Li, Anthony R. Ives

Faculty Publications

© 2017 The Authors. Methods in Ecology and Evolution © 2017 British Ecological Society A growing number of studies incorporate functional trait information to analyse patterns and processes of community assembly. These studies of trait–environment relationships generally ignore phylogenetic relationships among species. When functional traits and the residual variation in species distributions among communities have phylogenetic signal, however, analyses ignoring phylogenetic relationships can decrease estimation accuracy and power, inflate type I error rates and lead to potentially false conclusions. Using simulations, we compared estimation accuracy, statistical power and type I error rates of linear mixed models (LMM) and phylogenetic linear …

How Important Is Farm Profitability To Meat Goat Farmers?, Narayan P. Nyaupane, Jeffrey M. Gillespie, Kenneth W. Mcmillin Oct 2017

How Important Is Farm Profitability To Meat Goat Farmers?, Narayan P. Nyaupane, Jeffrey M. Gillespie, Kenneth W. Mcmillin

Faculty Publications

© 2017 American Registry of Professional Animal Scientists This study investigates United States meat goat producers’ goal structure and examines whether these goals are consistent with farm profitability. Data were collected using a nationwide mail survey, and 7 potential goals of meat goat farmers were analyzed. Results showed that “maximize profit” and “have family involved in agriculture” were the 2 most important goals, whereas “control weeds/vegetation” and “increase farm size” were the least-ranked goals. Regression results showed that farmer demographics, farm characteristics, economic indicators, and regional variables affected farmer goal structure. Results did not support a correlation between farm profitability …

Binding Of Herpes Simplex Virus 1 Ul20 To Godz (Dhhc3) Affects Its Palmitoylation And Is Essential For Infectivity And Proper Targeting And Localization Of Ul20 And Glycoprotein K, Shaohui Wang, Kevin R. Mott, Kolja Wawrowsky, Konstantin G. Kousoulas, Bernhard Luscher, Homayon Ghiasi

Faculty Publications

© 2017 American Society for Microbiology. Herpes simplex virus 1 (HSV-1) UL20 plays a crucial role in the envelopment of the cytoplasmic virion and its egress. It is a nonglycosylated envelope protein that is regulated as a ±1 gene. Two-hybrid and pulldown assays demonstrated that UL20, but no other HSV-1 gene-encoded proteins, binds specifically to GODZ (also known as DHHC3), a cellular Golgi apparatus-specific Asp-His-His-Cys (DHHC) zinc finger protein. A catalytically inactive dominant-negative GODZ construct significantly reduced HSV-1 replication in vitro and affected the localization of UL20 and glycoprotein K (gK) and their interactions but not glycoprotein C (gC). GODZ …

Variation In Seed Size Is Structured By Dispersal Syndrome And Cone Morphology In Conifers And Other Nonflowering Seed Plants, Andrew B. Leslie, Jeremy M. Beaulieu, Sarah Mathews Oct 2017

Variation In Seed Size Is Structured By Dispersal Syndrome And Cone Morphology In Conifers And Other Nonflowering Seed Plants, Andrew B. Leslie, Jeremy M. Beaulieu, Sarah Mathews

Faculty Publications

© 2017 The Authors. New Phytologist © 2017 New Phytologist Trust Seed size varies tremendously in plants and its evolution is influenced by multiple ecological and biological factors that are difficult to disentangle. In this study, we focus on understanding the role of seed dispersal by animals in the evolution of seed size in conifers, the most diverse extant nonflowering seed plant group. Relationships among seed size, dispersal syndrome, climate and cone morphology were analyzed across conifers using quantitative models of character evolution and phylogenetic regression techniques. Dispersal syndrome is a more consistent predictor of seed size within major extant …

Distribution And Female Reproductive State Differences In Orexigenic And Anorexigenic Neurons In The Brain Of The Mouth Brooding African Cichlid Fish, Astatotilapia Burtoni, Danielle T. Porter, David A. Roberts, Karen P. Maruska Oct 2017

Distribution And Female Reproductive State Differences In Orexigenic And Anorexigenic Neurons In The Brain Of The Mouth Brooding African Cichlid Fish, Astatotilapia Burtoni, Danielle T. Porter, David A. Roberts, Karen P. Maruska

Faculty Publications

© 2017 Wiley Periodicals, Inc. Integration of reproduction and metabolism is necessary for species survival. While the neural circuits controlling energy homeostasis are well-characterized, the signals controlling the relay of nutritional information to the reproductive axis are less understood. The cichlid fish Astatotilapia burtoni is ideal for studying the neural regulation of feeding and reproduction because females cycle between a feeding gravid state and a period of forced starvation while they brood developing young inside their mouths. To test the hypothesis that candidate neuropeptide-containing neurons known to be involved in feeding and energy homeostasis in mammals show conserved distribution patterns, …

Introduction: The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. Methods: This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008–2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coronary heart disease or stroke. We estimated …

Fitness Costs And Inheritance Of Cry2ab2 Resistance In Spodoptera Frugiperda (J.E. Smith), Binod Acharya, Graham P. Head, Paula A. Price, Fangneng Huang

Faculty Publications

Cry2Ab2 is a Bacillus thuringiensis (Bt) protein expressed in transgenic corn and cotton targeting above-ground lepidopteran pests including the fall armyworm, Spodoptera frugiperda (J.E. Smith). The objective of this study was to characterize fitness costs and inheritance of Cry2Ab2 resistance in S. frugiperda. To determine if fitness costs were associated with the resistance, life history parameters (larval survival, growth, development and egg production) of Cry2Ab2-resistant, -susceptible, and two reciprocal F1 colonies of S. frugiperda were assayed on non-toxic diet and non-Bt corn leaf tissue. The results showed that there were no significant differences among the four insect colonies for all …

Climate change is expected to lead to increases in drought frequency and severity, with deleterious effects on many ecosystems. Stomatal responses to changing environmental conditions form the backbone of all ecosystem models, but are based on empirical relationships and are not well-tested during drought conditions. Here, we use a dataset of 34 woody plant species spanning global forest biomes to examine the effect of leaf water potential on stomatal conductance and test the predictive accuracy of three major stomatal models and a recently proposed model. We find that current leaf-level empirical models have consistent biases of over-prediction of stomatal conductance …

Union Status, Educational Attainment, And Body Mass Index Among Emerging Adults, Rhiannon A. Kroeger Oct 2017

Union Status, Educational Attainment, And Body Mass Index Among Emerging Adults, Rhiannon A. Kroeger

Faculty Publications

This study uses fixed-effects regression modeling and three waves of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine whether union status and educational attainment interact to influence change in body mass index (BMI) during emerging adulthood. The results support the hypothesis that the effect of union status on change in BMI is smaller for those with more educational attainment. In particular, emerging adults with no college education experience significant increases in BMI associated with both marriage and cohabitation. The increases in BMI associated with marriage and cohabitation are significantly smaller for those with …

Transcription factors (TFs) regulate the expression of other genes to indirectly mediate stress resistance mechanisms. Therefore, when studying TF-mediated stress resistance, it is important to understand how TFs interact with genes in the genetic background. Here, we fine-mapped the aluminum (Al) resistance QTL Alt12.1 to a 44-kb region containing six genes. Among them is ART1, which encodes a C2H2-type zinc finger TF required for Al resistance in rice. The mapping parents, Al-resistant cv Azucena (tropical japonica) and Al-sensitive cv IR64 (indica), have extensive sequence polymorphism within the ART1 coding region, but similar ART1 expression levels. Using reciprocal near-isogenic lines (NILs) …

The Influence Of Föhn Winds On Glacial Lake Washburn And Palaeotemperatures In The Mcmurdo Dry Valleys, Antarctica, During The Last Glacial Maximum, M. K. Obryk, P. T. Doran, E. D. Waddington, C. P. Mckay

Faculty Publications

© Antarctic Science Ltd 2017. Large glacial lakes, including Glacial Lake Washburn, were present in the McMurdo Dry Valleys, Antarctica, during the Last Glacial Maximum (LGM) despite a colder and drier climate. To address the mechanism capable of generating enough meltwater to sustain these large lakes, a conceptual model was developed based on the warming potential of infrequent contemporary föhn winds. The model suggests that föhn winds were capable of generating enough meltwater to sustain large glacial lakes during the LGM by increasing degree days above freezing (DDAF) and prolonging the melt season. A present-day relationship between infrequent summer föhn …

Inheritance Study Of Resistance To The Herbicide Quizalofop-P-Ethyl In Rice And Development Of Provisia Hybrid Rice Germplasm, Jose Roberto Camacho Montero

LSU Doctoral Dissertations

In 2017, ProvisiaTM quizalofop-p-ethyl (QFE) resistant rice became a new alternative for the chemical control of in-season red rice (Oryza sativa L. sp. spontaneum) infestations in Louisiana rice farms. Until then, Clearfield® imidazolinone resistant rice was the only alternative that US farmers had for the efficient in-season chemical control of red rice. ProvisiaTM rice is a BASF Corporation patented technology that can serve as an alternative for rotation with Clearfield® rice. This strategy seeks to prevent outcrosses between red rice and herbicide resistant varieties, and consequently extend the life span of both technologies. This …
