High Altitude Diving In River Otters: Coping With Combined Hypoxic Stresses, Jamie R. Crait, Henry D. Prange, Noah A. Marshall, Henry J. Harlow, Clark Cotton, Merav Ben-David

Biology Faculty Publications

River otters (Lontra canadensis) are highly active, semi-aquatic mammals indigenous to a range of elevations and represent an appropriate model for assessing the physiological responses to diving at altitude. In this study, we performed blood gas analyses and compared blood chemistry of river otters from a high-elevation (2357 m) population at Yellowstone Lake with a sea-level population along the Pacific coast. Comparisons of oxygen dissociation curves (ODC) revealed no significant difference in hemoglobin-oxygen (Hb-O₂) binding affinity between the two populations - potentially because of demands for tissue oxygenation. Instead, high-elevation otters had greater Hb concentrations (18.7 …

Optimization Of Magnetic Powdered Activated Carbon For Aqueous Hg(Ii) Removal And Magnetic Recovery, Emily K. Faulconer, Natalia Hoogesteijn Von Reitzenstein, David W. Mazyck

Physical Sciences - Daytona Beach

Activated carbon is known to adsorb aqueous Hg(II). MPAC (magnetic powdered activated carbon) has the potential to remove aqueous Hg to less than 0.2 mg/L while being magnetically recoverable. Magnetic recapture allows simple sorbent separation from the waste stream while an isolated waste potentially allows for mercury recycling. MPAC Hg-removal performance is verified by mercury mass balance, calculated by quantifying adsorbed, volatilized, and residual aqueous mercury. The batch reactor contained a sealed mercury-carbon contact chamber with mixing and constant N₂(g) headspace flow to an oxidizingtrap. Mercury adsorption was performed using spiked ultrapure water (100 mg/L Hg). Mercury concentrations …

Orai1 Deficiency Leads To Heart Failure And Skeletal Myopathy In Zebrafish., Mirko Völkers, Nima Dolatabadi, Natalie Gude, Patrick Most, Mark A Sussman, David Hassel

Center for Translational Medicine Faculty Papers

Mutations in the store-operated Ca²⁺ entry pore protein ORAI1 have been reported to cause myopathies in human patients but the mechanism involved is not known. Cardiomyocytes express ORAI1 but its role in heart function is also unknown. Using reverse genetics in zebrafish, we demonstrated that inactivation of the highly conserved zebrafish orthologue of ORAI1 resulted in severe heart failure, reduced ventricular systolic function, bradycardia and skeletal muscle weakness. Electron microscopy of Orai1-deficient myocytes revealed progressive skeletal muscle instability with loss of myofiber integrity and ultrastructural abnormalities of the z-disc in both skeletal and cardiac muscle. Isolated Orai1-deficient cardiomyocytes showed loss …

Does Ideology Matter In Bankruptcy? Voting Behavior On The Courts Of Appeals, Jonathan Remy Nash, Rafael I. Pardo

William & Mary Law Review

This Article empirically examines whether courts of appeals judges cast ideological votes in the bankruptcy context. The empirical study is unique insofar as it is the first to examine the voting behavior of circuit court judges in bankruptcy cases. More importantly, it focuses on a particular type of dispute that arises in bankruptcy: debt-dischargeability determinations. The study implements this focused approach in order to reduce heterogeneity in result. We find, contrary to our hypotheses, no evidence that circuit court judges engage in ideological voting in bankruptcy cases. We also find, however, non-ideological factors—including the race of the judge and the …

The Role Of Charity In A Federal System, Brian Galle

William & Mary Law Review

This Article critiques the prevailing justification for subsidies for the charitable sector and suggests a new alternative. Existing rationales are based on an economic model that assumes a single government whose decisions are guided by a single median voter. I argue that this theory is unpersuasive when translated to federal systems, such as the United States, in which there may instead be thousands of competing local governments.

I then attempt to construct a theory of the charitable sector that takes account of interactions between charity, local government, and national government. In this revised account, charity is most important when federalism …

Plausibility Beyond The Complaint, Joseph A. Seiner

William & Mary Law Review

In Bell Atlantic Corp. v. Twombly, and Ashcroft v. Iqbal, the Supreme Court announced a new plausibility standard for a plaintiff’s allegations. The decisions may have even broader implications, however, as many federal district courts have already applied this pleading standard to a defendant’s affirmative defenses. This Article makes sense of Twombly and Iqbal in the context of the affirmative defense.

This Article addresses the two possible readings of Twombly and Iqbal: first, that the decisions are limited to a plaintiff’s civil complaint, and second, that a defendant must also comply with the Supreme Court’s plausibility standard by pleading enough …

Human Pulmonary Microvascular Endothelial Cells Support Productive Replication Of Highly Pathogenic Avian Influenza Viruses: Possible Involvement In The Pathogenesis Of Human H5n1 Virus Infection, Hui Zeng, Claudia Pappas, Jessica A. Belser, Katherine V. Houser, Weiming Zhong, Debra A. Wadford, Troy Stevens, Ron Balczon, Jacqueline M. Katz, Terrence M. Tumpey

University Faculty and Staff Publications

Highly pathogenic avian influenza (HPAI) H5N1 viruses continue to cause sporadic human infections with a high fatality rate. Respiratory failure due to acute respiratory distress syndrome (ARDS) is a complication among hospitalized patients. Since progressive pulmonary endothelial damage is the hallmark of ARDS, we investigated host responses following HPAI virus infection of human pulmonary microvascular endothelial cells. Evaluation of these cells for the presence of receptors preferred by influenza virus demonstrated that avian-like (α2-3-linked) receptors were more abundant than human-like (α2-6-linked) receptors. To test the permissiveness of pulmonary endothelial cells to virus infection, we compared the replication of selected seasonal, …

Discernible But Limited Introgression Has Occurred Where Trichinella Nativa And The T6 Genotype Occur In Sympatry, Detiger B. Dunams-Morel, Mason V. Reichard, Luigi Torretti, Dante S. Zarlenga, Benjamin Rosenthal

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The genetic diversity within and among parasite populations provides clues to their evolutionary history. Here, we sought to determine whether mitochondrial and microsatellite DNA variation could be used to evaluate the extent of differentiation, gene flow and historical reproductive isolation among the freeze resistant parasites Trichinella nativa and the Trichinella T6 genotype infecting wolverines (Gulo gulo) in Nunavut, Canada. To this end, we genotyped Trichinella isolates derived from the diaphragms of 39 wol- verines from this locale to reference strains of T. nativa and the Trichinella T6 genotype. Results showed that among a subset of 13 isolates examined, individuals resembled …

Sdsu Calf Value Discovery 2011 Summary Report, J.A. Walker, B.P. Holland, C.L. Wright, W.C. Rusche

South Dakota Beef Report, 2012

The Calf Value Discovery Program (CVD) allows cow-calf producers to gain knowledge of the finishing segment of the beef cattle industry and the marketing of fed cattle. Specifically, CVD provides an opportunity for cow-calf producers to learn how their calves perform in a feedlot and their carcass value when sold in a value-based marketing system. Each producer taking part in the program could consign a minimum of 5 steers weighing between 500 and 800 pounds to the CVD program. Animals were finished in a calf-fed program using typical diets and management protocols at VanderWal Yards (Bruce, SD). Carcass and feedlot …

Reducing Endophyte-Related Economic Losses, Don Ball

Forage Symposium at the Kentucky Cattlemen’s Convention

Tall fescue is native to Europe and was rarely planted in the United States until after the first four decades of the 20th century. However, since the release of the variety ‘Kentucky 31’ in 1943, this versatile cool season perennial grass has been widely planted for forage, turf, and conservation purposes, with most of the acreage planted consisting of this variety. “Fescue” has many attributes including wide adaptation, easy establishment, a long growing season, good forage and seed yield, and tolerance of a wide range of management conditions.

Horse Pastures: How Much Tall Fescue If Too Much?, S. Ray Smith, Tom Keene, Krista Cotten

Forage Symposium at the Kentucky Cattlemen’s Convention

Horse owners and managers have known for many years that endophyte infected tall fescue can cause a variety of issues with late term pregnant mares. Research has shown that grazing pure stands induces extreme physiological changes, while grazing pastures completely free of E+ tall fescue is virtually safe. However few pastures are pure stands or completely free of tall fescue. We know that the “danger level” changes over the seasons and that management can greatly reduce the risk of mares grazing infected pastures. Understanding what is “too much” can help us weigh the risks of symptoms to the cost of …

What Fescue Toxicosis Is Really Doing Inside Your Animals, Glen E. Aiken

Forage Symposium at the Kentucky Cattlemen’s Convention

Eighty years have passed since Dr. F.N. Fergus collected seed of tall fescue from that hillside at the Suiter Farm in Menifee County that led to the commercial release of the cultivar ‘Kentucky 31’. Fescue provided an opportunity to replace the briar and weed patches that dominated the rocky hillsides of Kentucky with productive forage. Plantings of tall fescue were numerous in the state during the 1940s and 1950s, and its hardiness and adaptability resulted in the grass spreading over much of the middle and upper southeastern USA, eventually covering a region we now call the “fescue belt”. It did …

New Tall Fescue Varieties For The Future, Timothy D. Phillips

Forage Symposium at the Kentucky Cattlemen’s Convention

Over the past few decades forage producers have seen several major changes in varieties of tall fescue. From the days of Kentucky 31 being the predominant variety, the first change was the first generation of endophyte-free tall fescue varieties. For many growers, these have been useful additions, especially when coupled with rotational grazing to reduce the risks of overgrazing, and practices of eradication of stands of toxic endophyte pastures and prevention of the reintroduction of toxic endophyte tall fescue seed into stands of endophyte-free varieties. However, overall these varieties often lacked the persistence of Kentucky 31 infected with the common …

Tall Fescue In Kentucky: The First 80 Years, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Tall fescue is a native of Europe. The exact date of its’ introduction into the United States is not known, but likely came as a contaminant in meadow fescue seed from England prior to 1880 (Figure 1). Tall Fescue was an entry in the National Herbarium Collection in 1879 and was grown in plots in Utah, Kentucky and Maryland (USDA) in 1880. In 1916, tall fescue plants were identified in Pullman, Washington with some of these plants taken to Corvallis, Oregon in 1918. Selections out of this initial planting were released in 1945 as the variety Alta.

Remaking A World Beyond State Demarcation: Emotion, Violence And Memory In Post-Conflict Oecussi, East Timor, Victoria Kumala Sakti

Conflict, Memory, and Reconciliation: Bridging past, present, and future

How do people in conflict-torn societies process, communicate, and remember past experiences of violence and how are emotions articulated and experienced in these processes? The traumatic effects of war and political violence have been widely documented and continue to be researched to deepen our understanding on how people deal with aftermath of violence. It is assumed that the experience and memory of conflict/war-related violence – independent from its specific socio-political causes – evokes emotions such as grief, anger, pain, fear, shame and guilt within the actors involved. This research is interested in the various cultural codifications of these emotional dimensions …

The Role Of Mitochondrial Dysfunction In Neurodegenerative Proteinopathies And Aging., Alejandro Ocampo

Open Access Dissertations

Age-related neurodegenerative proteinophaties, including polyglutamine (polyQ) diseases such as Huntington’s disease, are a group of disorders in which a single protein or a set of proteins misfold and aggregate resulting in a progressive and selective loss of anatomically or physiologically related neuronal systems. Despite evidence showing a clear relationship between mitochondrial dysfunction, aging and neurodegenerative proteinophaties, the extent of the mitochondrial respiratory chain deficits, the involvement of mitochondrial dysfunction and the mechanisms responsible for these processes are largely unknown. Using yeast models of cellular aging and polyQ disorders we show that mitochondrial dysfunction is an important contributor to the process …

Cost Analysis Of Cattle Feedlot Designs, J.M. Mrozinski, R.H. Pritchard, B.P. Holland, G.W. Warmann

South Dakota Beef Report, 2012

A cost analysis of fixed and non-fixed costs of gain was conducted on 3 cattle feedlot designs. The three facility designs compared were conventional open pens (OPN), open pens with shelter over the feeding area (OS), and a monoslope confinement barn (MON). The OPN design was the least expensive facility to build and operate. However, because of poorer cattle performance (P < 0.05), it was not the most cost effective. The MON design had significantly higher operating costs when compared to the OPN or OS designs, especially for the tractor/spreader (P < 0.05), skid loader (P < 0.10), labor (P < 0.05), and straw (P < 0.05). The operating and fixed costs, combined, made the MON design the most expensive cost of gain design (P < 0.05). The OS design was the most expensive facility to build but with current feed prices and the cattle performance, it was the most cost effective cattle feeding design.

Association Of The 5-Htt Gene-Linked Promoter Region (5-Httlpr) Polymorphism With Psychiatric Disorders: Review Of Psychopathology And Pharmacotherapy, George A. Kenna, Nick Roder-Hanna, Lorenzo Leggio, William H. Zywiak, James Clifford, Steven Edwards, John A. Kenna, Jessica Shoaff, Robert M. Swift

College of Nursing Faculty Publications

Serotonin (5-HT) regulates important biological and psychological processes including mood, and may be associated with the development of several psychiatric disorders. An association between psychopathology and genes that regulate 5-HT neurotransmission is a robust area of research. Identification of the genes responsible for the predisposition, development, and pharmacological response of various psychiatric disorders is crucial to the advancement of our understanding of their underlying neurobiology. This review highlights research investigating 5-HT transporter (5-HTTLPR) polymorphism, because studies investigating the impact of the 5-HTTLPR polymorphism have demonstrated significant associations with many psychiatric disorders. Decreased transcriptional activity of the S allele (“risk allele”) …

A Modus Vivendi? Sex, Marriage & The Church, William L. Portier, Nancy Dallavalle, Christopher C. Roberts, Tina Beattie, R. R. Reno, Patricia Hampl, Luke Timothy Johnson, Leslie Woodcock Tentler, Paul Baumann

Theology and Religious Studies Faculty Publications

During the 1960s, nearly 80 percent of adult Americans were married. A recent analysis of U.S. census data reported that only 52 percent of adult Americans were married in 2009. That is the lowest percentage reported in the 100 years the Census Bureau has collected such information. The reasons for this dramatic cultural shift are well known: high rates of divorce; changing attitudes toward premarital sex; social acceptability of cohabitation; the weakening of the stigma surrounding out-of-wedlock births and single parenting; the postponement of marriage and children for academic or professional reasons.

Uterine Dysfunction In Biglycan And Decorin Deficient Mice Leads To Dystocia During Parturition., Zhiping Wu, Abraham W Aron, Elyse E Macksoud, Renato V Iozzo, Chi-Ming Hai, Beatrice E Lechner

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Cesarean birth rates are rising. Uterine dysfunction, the exact mechanism of which is unknown, is a common indication for Cesarean delivery. Biglycan and decorin are two small leucine-rich proteoglycans expressed in the extracellular matrix of reproductive tissues and muscle. Mice deficient in biglycan display a mild muscular dystrophy, and, along with mice deficient in decorin, are models of Ehlers-Danlos Syndrome, a connective tissue anomaly associated with uterine rupture. As a variant of Ehlers-Danlos Syndrome is caused by a genetic mutation resulting in abnormal biglycan and decorin secretion, we hypothesized that biglycan and decorin play a role in uterine function. Thus, …

Mureithi's Icyizere: Hope: Reconciliation, Rehumanization, And Collective Remembrance/Rebuilding Of Sacred And Safe Space, Eric Aoki, Kyle Jonas

Conflict, Memory, and Reconciliation: Bridging past, present, and future

In this essay we assess Patrick Mureithi’s (2009) documentary, ICYIZERE, as a document of collective memory (Blair, Dickinson, and Ott, 2010, p. 6).[1] Focusing on the power of memory in/of place, we argue that the local and national sites of atrocity and healing between perpetrators and survivors of the Rwandan genocide (i.e., a site of violence as well as the site of the reconciliatory workshop between Hutus and Tutsis in the film) serve as a sacred ground for healing and that this sacred ground is produced through negotiations of (dialectical) tensions between past and present and individual memory and …
