In Ovo Selenium (Se) Injection Of Incubating Chicken Eggs: Effects On Embryo Viability, Tissue Se Concentration, Lipid Peroxidation, Immune Response And Post Hatch Development, Lizza M. Macalintal

Theses and Dissertations--Animal and Food Sciences

Studies were conducted to investigate the effects of in ovo injection of selenium (Se) either as seleno-methionine (Se-Met) or sodium selenite (Na₂SeO₃) into the yolk of incubating eggs on tissue Se concentration, embryo livability, lipid peroxidation, immune response and growth performance. When white-shelled eggs were injected with 0.1ml of solutions providing 0, 2.5, 5, 10 or 20 μg Se/egg, no detrimental effects on embryo viability at 20 days of incubation were noted. The effects on tissue Se concentrations suggested that Se-Met and Na₂SeO₃ were metabolized differently by the chick embryo. In a subsequent …

Foraging And Roosting Behaviors Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii) At The Northern Edge Of The Species Range, Joseph S. Johnson

Theses and Dissertations--Animal and Food Sciences

Bat populations in the eastern United States are currently declining at unprecedented rates as a result of habitat loss, commercial wind energy development, and white-nose syndrome. Effective conservation of these declining populations requires knowledge of several aspects of summer and winter ecology, including daytime habitat use (day-roost selection and social behaviors), nocturnal habitat use (foraging habitat selection, prey selection, and prey abundance), and winter hibernation (torpor) patterns. This dissertation addresses these questions for Rafinesque’s big-eared bat (Corynorhinus rafinesquii), a species of conservation concern in the southeastern United States. Kentucky represents the northern edge of the range of Rafinesque’s …

Effect Of Feeding A Blend Of Naturally-Contaminated Corn On Nutrient Digestibility And Feed Preference In Weanling Pigs, Carlos Santiago Escobar

Theses and Dissertations--Animal and Food Sciences

Two experiments were conducted to determine the effect of feeding diets with a 2009 and 2010 naturally-contaminated corn to weaning pigs. For both experiments three diets were blended to contain 100% 2010 naturally-contaminated corn (control), 50-50% blend of the 2009 naturally-contaminated corn and 2010 corn (Diet 2), and 100% 2009 naturally-contaminated corn (Diet 3). In Exp. 1, 24 crossbred pigs with an average body weight of 7.64 ± 0.70 kg were allotted to 4 replicates of 3 treatments with 2 pigs per pen, on the basis of gender, litter mate, and BW in a randomized complete block design. Fecal and …

Evaluating The Effects Of Maternal And Progeny Dietary Supplementation Of Selenium Yeast And Vitamin E On The Performance Of Broiler-Breeder Hens And Performance And Meat Quality Of Progeny, Anthony D. Quant

Theses and Dissertations--Animal and Food Sciences

The objectives of these experiments were to evaluate the effects of selenium (Se) and vitamin E (Vit.E) supplementation in maternal and progeny diets on the performance of breeder hens and the performance and meat quality characteristics of progeny.

Inclusion of Se, as Se yeast, in the diets of developing broiler breeder pullets resulted in greater Se accumulation of Se (P<0.01) in liver, pancreas, and breast tissues than when Se yeast was not provided. Improving the overall Se status of breeder pullets in the early stages may help maintain adequate tissue Se concentrations during egg production.

Maternal supplementation of Se yeast and Vit.E increased the liver and breast Se concentration (P<0.05) of newly hatched chicks compared to the chicks originating from hens not receiving dietary Se. At 7d of age, Se yeast supplementation in either the chick or maternal diet increased breast and liver Se concentrations (P<0.01). At 14d of age, breast and liver Se concentrations remained the highest for chicks supplemented with Se yeast (P<0.01), however there was no effect of maternal Se supplementation. Vitamin E supplementation in either the chick or maternal diets did not affect the liver Vit.E concentrations of chicks at 7 or 14d of age.

Supplementing broiler diets with Se yeast and Vit.E improved the meat quality characteristics of raw and marinated breast fillets. The Se …

Influence Of Dietary Selenium Supplementation Form On Hepatic Transcriptome Profiles Of Maturing Beef Heifers, Zhi Zhang

Theses and Dissertations--Animal and Food Sciences

Our objective was to know how the hepatic transcriptome expression of growing beef (Angus-cross) heifers (0.5 kg gain/day) was affected by the feeding of different sources of dietary (3 mg/day) Se supplements: inorganic Se (ISe, sodium selenite), organic (OSe, Sel-Plex®), or a blend (1.5 mg:1.5 mg) of ISe:OSe (Mix), compared to the adequate but non-Se supplemented “Control”. The biopsied hepatic tissues of these four groups heifers collected at day 168 (when liver Se assimilation had stabilized) after supplements of Se, was subjected to the microarray analysis to assess Se treatment effects.

The results suggest that there were clear differences in …

A Judicial Retrospective: Significant Decisions By The Arkansas Supreme Court From 1991 Through 2011, Robert L. Brown

University of Arkansas at Little Rock Law Review

In 2008, a study issued by the University of Chicago ranked the Arkansas Supreme Court as the second best state supreme court in the nation, based on the justices' productivity in issuing opinions, quality of opinions, and independence from partisan pressures. The last two decades have seen the Arkansas Supreme Court issue a multitude of opinions considering separation of powers, public education, prior restraint of the press, expanded rights under the Arkansas Constitution, class actions and tort reform.

This article highlights many of the most significant opinions from the last two decades and comments on their impact in Arkansas and …

A Brief Summary Of Decisions From The Arkansas Supreme Court Affecting Gays And Lesbians, Anthony L. Mcmullen

University of Arkansas at Little Rock Law Review

Half of Arkansans believe that sex-sex relationships should not be afforded legal recognition, including recognition in the form of a civil union or domestic partnership. Further, Arkansas is one of thirty states to constitutionally define marriage as the legal union between a man and a woman. Nonetheless, the gay and lesbian civil rights movement has been afforded protection in the courts through Arkansas Supreme Court decisions protecting same sex couples' rights.

Starting in 2002, the Arkansas Supreme Court has provided at least some protection to same sex couples and their families through decisions where the Court could have declined to …

Chemical And Electrical Approaches To Sedation Of Cobia: Induction, Recovery, And Physiological Responses, Jesse Trushenski, John C. Bowzer, James D. Bowker, Michael H. Schwarz

Publications

To support the growing interest in marine fisheries research in areas such as biotelemetry, tagging, and tracking, we assessed the ability of various sedatives to facilitate this research in juvenile cobias Rachycentron canadum (∼300 g), namely, tricaine methanesulfonate (MS-222; 150 mg/L), carbon dioxide (CO₂; ∼750 mg/L), eugenol (60 mg/L), benzocaine (150 mg/L), and pulsed-DC electrosedation (100 V, 30 Hz, 25% duty cycle, 5-s exposure). Induction times (CO₂ [z] > benzocaine [y] > eugenol [y] > MS-222 [y] > electrosedation [x]), recovery of equilibrium (CO₂ [z] > eugenol [z] > MS-222 [y] > benzocaine [y] > electrosedation [x]), and responsiveness to tactile stimulus (eugenol [z] …

Characterizing Tukey H And Hh-Distributions Through L-Moments And The L-Correlation, Todd C. Headrick, Mohan D. Pant

Publications

This paper introduces the Tukey family of symmetric h and asymmetric hh-distributions in the contexts of univariate L-moments and the L-correlation. Included is the development of a procedure for specifying nonnormal distributions with controlled degrees of L-skew, L-kurtosis, and L-correlations. The procedure can be applied in a variety of settings such as modeling events (e.g., risk analysis, extreme events) and Monte Carlo or simulation studies. Further, it is demonstrated that estimates of L-skew, L-kurtosis, and L-correlation are substantially superior to conventional product-moment estimates of skew, kurtosis, and Pearson correlation in terms …

Resistance To Soybean Cyst Nematode: Rhg1, Ahmad Walid Afzali, Ali Srour, Aparna Natarajan, Navinder Saini, M Javed Iqbal, Matt Geisler, Hany A. El Shemy, David A. Lightfoot

Articles

The genes underlying rhg1 lie at a sometimes dominant sometimes co-dominant locus, necessary for resistance to all Hg types of the soybean (Glycine max (L.) Merr.) cyst nematode (Heterodera glycines). Genomic research identified; nucleotide changes within a candidate gene encoding a receptor like kinase (RLK) that were capable of altering root development and thereby part of the resistance to Hg types 0 (race 3); changes in a laccase that are capable of altering cyst development; and genes underlying changes in membrane biology. This set of three genes are subject to co-selection with a modifier locus on another …

Genetic Analysis Of Root And Shoot Traits In The ‘Essex’ By ‘Forrest’ Recombinant Inbred Line (Ril) Population Of Soybean [Glycine Max (L.) Merr.], William Brensha Brensha, Stella K. Kantartzi, Khalid Meksem, Robert L. Grier Iv, Abdelali Barakat, David A. Lightfoot, My Abdelmajid Kassem

Articles

Crop productivity is severely reduced by water deficit and drought in many plant species including soybean. Improved root and shoot traits can contribute to drought tolerance ability of the plant. This research was conducted to identify QTL that underlie several root and shoot traits in the ‘Essex’ by ‘Forrest’ (ExF RILs, n=94) recombinant inbred line (RIL) soybean population. Field collected samples were used for gathering phenotypic data of basal root thickness (BRT), lateral root number (LRN), maximum root length (MRL), root fresh weight (RFW), root dry weight (RDW), shoot fresh weight (SFW), shoot dry weight (SDW), and calculating RFW/SFW, and …

Amyloidogenic neurodegenerative diseases are incurable conditions with high social impact that are typically caused by specific, largely disordered proteins. However, the underlying molecular mechanism remains elusive to established techniques. A favored hypothesis postulates that a critical conformational change in the monomer (an ideal therapeutic target) in these “neurotoxic proteins” triggers the pathogenic cascade. We use force spectroscopy and a novel methodology for unequivocal single-molecule identification to demonstrate a rich conformational polymorphism in the monomer of four representative neurotoxic proteins. This polymorphism strongly correlates with amyloidogenesis and neurotoxicity: it is absent in a fibrillization-incompetent mutant, favored by familial-disease mutations and diminished …

Morfpred, A Computational Tool For Sequence-Based Prediction And Characterization Of Short Disorder-To-Order Transitioning Binding Regions In Proteins, Fatemeh Miri Disfani, Wei-Lun Hsu, Marcin J. Mizianty, Christopher J. Oldfield, Bin Xue, A. Keith Dunker, Vladimir N. Uversky, Lukasz Kurgan

Molecular Medicine Faculty Publications

Motivation: Molecular recognition features (MoRFs) are short binding regions located within longer intrinsically disordered regions that bind to protein partners via disorder-to-order transitions. MoRFs are implicated in important processes including signaling and regulation. However, only a limited number of experimentally validated MoRFs is known, which motivates development of computational methods that predict MoRFs from protein chains.

Results: We introduce a new MoRF predictor, MoRFpred, which identifies all MoRF types (α, β, coil and complex). We develop a comprehensive dataset of annotated MoRFs to build and empirically compare our method. MoRFpred utilizes a novel design in which annotations generated by sequence …

Understanding Viral Transmission Behavior Via Protein Intrinsic Disorder Prediction: Coronaviruses, Gerard Kian-Meng Goh, A. Keith Dunker, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Besides being a common threat to farm animals and poultry, coronavirus (CoV) was responsible for the human severe acute respiratory syndrome (SARS) epidemic in 2002–4. However, many aspects of CoV behavior, including modes of its transmission, are yet to be fully understood. We show that the amount and the peculiarities of distribution of the protein intrinsic disorder in the viral shell can be used for the efficient analysis of the behavior and transmission modes of CoV. The proposed model allows categorization of the various CoVs by the peculiarities of disorder distribution in their membrane (M) and nucleocapsid (N). This categorization …

Smiles As Signals Of Lower Status In Football Players And Fashion Models: Evidence That Smiles Are Associated With Lower Dominance And Lower Prestige, Timothy Ketelaar, Bryan L. Koenig, Daniel Gambacorta, Igor Dolgov, Daniel Hor, Jennifer Zarzoza, Cuauhtémoc Luna-Nevarez, Micki Klungle, Lee Wells

WCBT Faculty Publications

Across four studies, the current paper demonstrates that smiles are associated with lower social status. Moreover, the association between smiles and lower status appears in the psychology of observers and generalizes across two forms of status: prestige and dominance. In the first study, faces of fashion models representing less prestigious apparel brands were found to be more similar to a canonical smile display than the faces of models representing more prestigious apparel brands. In a second study, after being experimentally primed with either high or low prestige fashion narratives, participants in the low prestige condition were more likely to perceive …

A Developing Norm Under International Law: A Case Study Of The Proliferation Security, Sunan J. Rustam

Maurer Theses and Dissertations

Introduced in 2003, the Proliferation Security Initiative (PSI) has developed into a norm of international law. The PSI statement of interdiction has gained status as a principle for conducting maritime interdiction to stop the illicit trafficking of weapons of mass destruction. As of 2011, ninety-eight countries, more than 50% of all countries in the world, have committed to practicing PSI. In addition, eleven ship-boarding agreements concluded with major flag-state countries have given the PSI access to more than 75% of commercial ships worldwide. In the international forum, the PSI has influenced international law, evidenced by the passing of U.N. Security …

The Feasibility Of Growing Switchgrass In China For Lignocellulosic Ethanol Production, Ronne Allen Adkins

Electronic Theses and Dissertations Archive

Switchgrass (Panicum virgatum L.) is a perennial plant species native to the United States that is capable of adapting to a wide variety of geographic and climate conditions. There are two ecotypes of switchgrass: lowland varieties which favor areas with higher rainfall and longer growing seasons and upland varieties which favor areas with cooler and drier climate conditions with shorter growing seasons. Switchgrass has the capacity to become a significant bioenergy feedstock for lignocellulosic ethanol conversion. The purpose of this dissertation is to determine which regions in China are suitable for switchgrass production, estimate potential biomass yield, and examine the …

Ethnicity And Impressions Of Personality Using The Five-Factor Model: Stereotyping Or Cultural Sensitivity?, Andrea Kay Cooper, David Chin Evans

Ethnic Studies Review

The current research investigates whether communities use ethnicity as a cue when forming personality impressions of others. Past research has shown that dress, smiling, hairstyle, and even facial symmetry of targets produce systematic differences in personality impressions across the domains of the Five Factor model of personality. We investigated whether the stated or apparent ethnicity of groups and individuals also produce stereotypic impressions of personality. This study compared impressions across members and non-members of the target groups and examined "cue utility" i.e. whether impressions of the groups agreed with aggregated self-impressions by group members. In all, the results clearly suggest …
