Corn Residue Removal Effects On Subsequent Yield, Brian J. Wienhold, Gary E. Varvel, Virginia L. Jin Jin, Rob B. Mitchell, Kenneth P. Vogel

Nebraska Beef Cattle Reports

Corn residue is used for forage and feed, but residue removal effects on soil properties and yield is a concern. Residue removal effects on corn yields and soil organic carbon is site specific. Removing 50% of the residue from rain fed sites reduced corn yield by 1.9 bu/ac, whereas removing 40% of the residue from irrigated sites increased corn yield by 15.4 bu/ac. However, removing 53% of the residue increased soil erosion by 30%. Agronomic practices such as reduced tillage, cover crops, or manure may offset residue removal impacts. Residue removal should be based on site-specific characteristics and management, but …

Nitrogen Fertilization And Ddgs Supplementation Reduces Annual Weeds In Pastures, John A. Guretzky, Laura K. Snell, John C. Soper Soper, Walter H. Schacht, Terry Klopfenstein, Stephanie K. Pruitt

Nebraska Beef Cattle Reports

Ongoing research has found body weight (BW) gains of steers supplemented with corn dried distillers grains plus solubles (DDGS) on unfertilized smooth bromegrass pasture (SUPP) to be greater than unsupplemented steers on N fertilized (FERT) and unfertilized, control (CONT) smooth bromegrass pasture. In the seventh year of the study, annual weeds increased to 20%, 9%, and 2% of relative cover within CONT, SUPP, and FERT pastures, respectively. Supplementation of DDGS on unfertilized pastures improves steer BW gains and reduces N inputs while providing intermediate resistance to annual weed invasion. AnnualN fertilization maximizes forage yield and minimizes annual weeds in pasture.

Replacing Steam-Flaked Corn And Dry Rolled Corn With Condensed Distillers Solubles In Finishing Diets, Alex H. Titlow, Adam L. Shreck, Stephanie A. Furman Furman, Karla Jenkins, Matt K. Luebbe, Galen E. Erickson

Nebraska Beef Cattle Reports

The interaction between corn processing method and condensed distillers solubles (CDS) was evaluated using either steam-flaked corn (SFC) or dry rolled corn (DRC). As CDS replaced corn at either 15 or 30% of the diet DM, DMI intake decreased quadratically for both SFC and DRC. Within DRC- based diets, ADG increased quadratically with 15% CDS being greatest and F:G improved quadratically with 30% inclusion being best. When SFC was used as the grain source, ADG increased linearly and F:G improved quadratically with increasing levels of CDS. A greater performance response was observed with SFC compared to DRC when feeding increased …

The Effect Of Lameness On Average Daily Gain In Feedlot Steers, Giselle T. Kruse, Richard R. Randle, Douglas E. Hostetler Hostetler, Gary K. Tibbetts, Dicky D. Griffin, Kathryn J. Hanford, Terry Klopfenstein, Galen E. Erickson, Brandon L. Nuttelman, David R. Smith

Nebraska Beef Cattle Reports

The objective of this study was to test the effects of lameness on average daily gain (ADG) of feedlot steers. We evaluated two feedlot health data sets: 1) 14,798 steers from a 14-year period (1993 to 2006) at the Meat Animal Research Center (USDA MARC) near Clay Center, Neb.; and 2) 16,766 steers from an 8-year period (2002 to 2009) at the University of Nebraska Agricultural Research and Development Center (ARDC) near Mead, Neb. The ADG for USDA MARC steers with lameness late in the feeding period (≥ 60 days) was 0.04 lb./day less than steers without lameness. The ADG …

Including Next Enhance® Essential Oils In Finishing Diets On Performance With Or Without Rumensin® And Tylan®, Curtis J. Bittner, Galen E. Erickson, Karla Jenkins Jenkins, Matt K. Luebbe, Troy Wistuba

Nebraska Beef Cattle Reports

Finishing cattle performance was evaluated using NEXT ENHANCE essential oils in finishing diets. Treatments consisted of 1) control (CON), 2) NEXT ENHANCE at 300 mg/day (NE), 3) Rumensin and Tylan at 360 and 90 mg/day, respectively (RT), or 4) NEXT ENHANCE plus Rumensin and Tylan (NERT). No NEXT ENHANCE by Rumensin/Tylan interaction was observed. Steers fed Rumensin/Tylan had decreased F:G and increased live final BW and marbling score. The prevalence of liver abscesses decreased 46% when steers were fed Rumensin/Tylan. Including NEXT ENHANCE in finishing diets did not impact performance or carcass characteristics.

The Effect Of Commensal Microbial Communities On The Fecal Shedding Of Shiga Toxin-Producing E. Coli (Stec) In Beef Cattle, Nirosh D. Aluthge, Yoshitha A. Wanniarachchi, Brandon L. Nuttelman Nuttelman, Cody J. Schneider, Terry Klopfenstein, Galen E. Erickson, Jayne E. Stratton, Samodha C. Fernando

Nebraska Beef Cattle Reports

This ongoing study compares the gut microbial community composition between shedding steers high in shiga toxin-producing E. coli (STEC) counts and low-shedding steers. Shedders were identified among 170 beef animals over three time periods using selective microbiological culture media. The isolated bacterial cultures were confirmed to be STEC using PCR, 16s rRNA sequencing and a shiga toxin immunoassay. The most abundant strains found in the cattle feces were those belonging to the serogroups O111 (40.3%) and O157:H7 (37.3%), with O103 (8.3%), O26 (6.0%), O83 (4.5%), and O55 (3.0%) being detected in much lower numbers . Out of the 52 animals …

Hormonal Residues In Feedlot Pens And Runoff, Terry L. Mader, Leslie J. Johnson, Shannon L. Bartelt-Hunt Hunt, Daniel D. Snow, William L. Kranz, Charles A. Shapiro, Simon Van Donk, David P. Shelton, David Tarkalson, Tian Zhang

Nebraska Beef Cattle Reports

Two identically designed trials were conducted in separate years at the University of Nebraska Haskell Agricultural Laboratory, Concord, Neb., using 192 crossbred heifers (96/trial). Within a trial, heifers were assigned randomly to 2 groups (3 pens/group): 1) treatment (TRT) animals were administered synthetic hormones via subcutaneous implants (Ralgro and Revalor-H) and fed Melengesterol Acetate (MGA), or 2) control (CON) animals with no synthetic hormone provided.

Gains and feed conversions were 18.8 and 7.5% better, respectively, for TRT, while CON had 16.7% greater choice and prime carcasses. In runoff samples, progesterone was greater for CON. With the exception of androsterone, average …

Anaerobic Digestion Of Finishing Cattle Manure, Andrea K. Watson, Galen E. Erickson, Terry Klopfenstein Klopfenstein, Samodha C. Fernando, Jana L. Harding

Nebraska Beef Cattle Reports

Utilizing manure from cattle fed distillers grains in anaerobic digesters improved methane production and DM degradation of manure compared to manure from cattle fed no distillers grains. Manure from cattle fed in open lot pens had soil contamination which decreased OM content and led to decreased total methane production (L/day), but not when expressed as methane/g OM. If ash buildup is avoided, open lot manure can be used as anaerobic digester feedstock.

Effect Of Development System On Heifer Performance And Primiparous Heifer Grazing Behavior, Adam F. Summers, T. L. Meyer, Jacqueline Musgrave Musgrave, Stetson P. Weber, Rick N. Funston

Nebraska Beef Cattle Reports

The effect of heifer development system on primiparous heifer performance grazing corn residue during late gestation was investigated. Weaned heifers grazing corn residue tended to have reduced final BW after corn residue grazing compared to heifers grazing winter range. However reproductive performance for the two treatments was similar. When grazing corn residue as pregnant heifers during late gestation, heifers developed on corn residue had improved ADG compared to drylot-developed heifers and tended to have increased ADG compared to winter range-developed heifers. Adaptation to corn residue grazing as a developing heifer improves primiparous heifer performance grazing corn residue during late gestation.

Molecular Architecture Of The Uncleaved Hiv-1 Envelope Glycoprotein Trimer, Youdong Mao, Luis Castillo-Menendez, Liping Wang, Christopher Gu, Alon Herschhorn, Anik Désormeaux, Andrés Finzi, Shi-Hua Xiang, Joseph Sodroski

Nebraska Center for Virology: Faculty Publications

The human immunodeficiency virus (HIV-1) envelope glycoprotein (Env) trimer, a membrane-fusing machine, mediates virus entry into host cells and is the sole virusspecific target for neutralizing antibodies. Binding the receptors, CD4 and CCR5/CXCR4, triggers Env conformational changes from the metastable unliganded state to the fusion-active state. We used cryo-electron microscopy to obtain a 6-Å structure of the membranebound, heavily glycosylated HIV-1 Env trimer in its uncleaved and unliganded state. The spatial organization of secondary structure elements reveals that the unliganded conformations of both gp120 and gp41 subunits differ from those induced by receptor binding. The gp120 trimer association domains, which …

Variations In The Biological Functions Of Hiv-1 Clade C Envelope In A Shiv-Infected Rhesus Macaque During Disease Progression, For Yue Tso, Levon Abrahamyan, Shiu-Lok Hu, Ruth M. Ruprecht, Charles Wood

Nebraska Center for Virology: Faculty Publications

A better understanding of how the biological functions of the HIV-1 envelope (Env) changes during disease progression may aid the design of an efficacious anti-HIV-1 vaccine. Although studies from patient had provided some insights on this issue, the differences in the study cohorts and methodology had make it difficult to reach a consensus of the variations in the HIV-1 Env functions during disease progression. To this end, an animal model that can be infected under controlled environment and reflect the disease course of HIV-1 infection in human will be beneficial. Such an animal model was previously demonstrated by the infection …

Kaposi’S Sarcoma-Associated Herpesvirus Transactivator Rta Induces Cell Cycle Arrest In G0/G1 Phase By Stabilizing And Promoting Nuclear Localization Of P27Kip, Pankaj Kumar, Charles Wood

Nebraska Center for Virology: Faculty Publications

The Kaposi’s sarcoma-associated herpesvirus (KSHV) immediate-early gene, replication, and transcription activator (KRta) is a key viral protein that serves as the master regulator for viral lytic replication. In this study, we investigated the role of K-Rta in cell cycle regulation and found that the expression of K-Rta in doxycycline (Dox)-inducible BJAB cells induced cell cycle arrest in G₀/G₁ phase. Western blot analysis of key cell cycle regulators revealed that K-Rta-mediated cell cycle arrest was associated with a decrease in cyclin A and phosphorylated Rb (pS807/pS811) protein levels, both markers of S phase progression, and an increase in …

Low-Abundance Resistant Mutations In Hiv-1 Subtype C Antiretroviral Therapy-Naïve Individuals As Revealed By Pyrosequencing, Sandra Gonzalez, Damien C. Tully, Clement Gondwe, Charles Wood

Nebraska Center for Virology: Faculty Publications

Given the recent scale-up of antiretroviral therapy (ART) in sub-Saharan Africa, we sought to determine how often and at what levels do drug-resistant mutant variants exist in ART-naïve HIV subtype C infected individuals. Samples from 10 ART-naïve Zambian individuals were subjected to ultra-deep pyrosequencing (UDPS) to characterize the frequency of low-abundance drug resistance mutations in the pol gene. Low-abundance clinically relevant variants were detected for nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) in eight of the ten subjects. Intermediate to high-level resistance was predicted for the majority of NRTIs. Mutations conferring resistance to …

Clade C Hiv-1 Isolates Circulating In Southern Africa Exhibit A Greater Frequency Of Dicysteine Motif-Containing Tat Variants Than Those In Southeast Asia And Cause Increased Neurovirulence, Vasudev R. Rao, Ujjwal Neogi, Joshua S, Talboom, Ligia Padilla, Mustafizur Rahman, Cari Fritz-French, Sandra Gonzalez-Ramirez, Anjali Verma, Charles Wood, Ruth M. Ruprecht, Udaykumar Ranga, Tasnim Azim, Vinayaka R. Prasad

Nebraska Center for Virology: Faculty Publications

Background: HIV-1 Clade C (Subtype C; HIV-1C) is responsible for greater than 50% of infections worldwide. Unlike clade B HIV-1 (Subtype B; HIV-1B), which is known to cause HIV associated dementia (HAD) in approximately 15% to 30% of the infected individuals, HIV-1C has been linked with lower prevalence of HAD (0 to 6%) in India and Ethiopia. However, recent studies report a higher prevalence of HAD in South Africa, Zambia and Botswana, where HIV-1C infections predominate. Therefore, we examined whether Southern African HIV-1C is genetically distinct and investigated its neurovirulence. HIV-1 Tat protein is a viral determinant of neurocognitive dysfunction. …

Evaluation Of A New Chemistry For Rangeland Grasshopper Control, Jeffrey Bradshaw, Karla Jenkins, Sean Doyle Whipple Whipple, Rick Patrick

Nebraska Beef Cattle Reports

A grasshopper control study was conducted to evaluate the effectiveness of a new class of systemic chemical. The new pesticide Prevathon^® (high and low levels) was compared to Coragen^®, Dimilin^®, and a nontreated check. Grasshoppers were numerically reduced the most by Coragen and Prevathon, though not significant. The highest level of Prevathon did not numerically impact beneficial insects in general. Biomass and forage quality were not significantly impacted by chemical treatment. However, forage biomass was numericallygreatest for the highest level of Prevathon. Prevathon appears to be an acceptable systemic pesticide for grasshopper control with minimal …

Department of Mechanical and Materials Engineering: Faculty Publications

This review provides an overview of the effect of blood flow on endothelial cell (EC) signalling pathways, applying microarray technologies to cultured cells, and in vivo studies of normal and atherosclerotic animals. It is found that in cultured ECs, 5–10% of genes are up- or down-regulated in response to fluid flow, whereas only 3–6% of genes are regulated by varying levels of fluid flow. Of all genes, 90%are regulated by the steady part of fluid flow and 10% by pulsatile components. The associated gene profiles show high variability from experiment to experiment depending on experimental conditions, and importantly, the bioinformatical …

A Virus-Encoded Potassium Ion Channel Is A Structural Protein In The Chlorovirus Paramecium Bursaria Chlorella Virus 1 Virion, Giulia Romani, Adrianna Piotrowski, Stefan Hillmer, James Gurnon, James L. Van Etten, Anna Morani, Gerhard Thiel, Brigitte Hertel

James Van Etten Publications

Most chloroviruses encode small K+ channels, which are functional in electrophysiological assays. The experimental finding that initial steps in viral infection exhibit the same sensitivity to channel inhibitors as the viral K+ channels has led to the hypothesis that the channels are structural proteins located in the internal membrane of the virus particles. This hypothesis was questioned recently because proteomic studies failed to detect the channel protein in virions of the prototype chlorovirus Paramecium bursaria chlorella virus 1 (PBCV-1). Here, we used a mAb raised against the functional K+ channel from chlorovirus MA-1D to search for the viral K+ channel …

Potassium Ion Channels: Could They Have Evolved From Viruses?1[W], Gerhard Thiel, Anna Moroni, Guillaume Blanc, James L. Van Etten

James Van Etten Publications

Cells communicate among themselves by electrical activity. Sophisticated membrane-embedded proteins, called ion channels, catalyze rapid, selective, and regulated ion fluxes across membranes (Hille, 2001). The resulting membrane currents are responsible for neuronal activity and the systemic propagation of electrical signals in animals. The activity of some channels is important for muscle movement in animals or growth in plants; other channels sense the concentration of physiological signals and modulate key processes in all kinds of eukaryotic cells. Among the many diverse ion channels in higher organisms, K+ channels are among the most important. One feature of K+ channels is that they …

Personalizing Aac For People With Aphasia: The Role Of Text And Pictures, Aimee R. Dietz, Kristy S.E. Weissling, Julie Griffith, Miechelle L. Mckelvey

Department of Special Education and Communication Disorders: Faculty Publications

Over time, and with intensive instruction, people with aphasia (PWAs) can learn to use grid-based, categorically organized, high-technology AAC layouts during structured tasks (e.g., Hough & Johnson, 2009). In an effort to reduce the training intensity required to teach PWAs to use AAC; researchers developed visual scene displays (VSDs), designed to complement the residual cognitive and linguistic abilities of PWAs by tapping their intact episodic memory. VSD interfaces incorporate personally relevant (PR) photos, text, and speech output (Dietz, McKelvey, & Beukelman, 2006; Weissling & Beukelman, 2006). VSDs appear to facilitate improved communication success (e.g., McKelvey, Dietz, Hux, Weissling, & Beukelman, …

Electropalatography As An Adjunct To Nonspeech Orofacial Myofunctional Disorder Assessments: A Feasibility Study, Alana Mantie-Kozlowski, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

The purpose of this study was to determine if electropalatography (EPG) would be a useful adjunct and feasible option for those conducting clinical assessments of individuals with suspected nonspeech orofacial myofunctional disorders (NSOMD). Three females (two adults, one child) were referred by their orthodontist for assessment of suspected NSOMD. Three adults and one child without NSOMD were recruited for the purpose of evaluating methodological construct, and to provide comparisons for participants with NSOMD. Using EPG, lingual-palatal timing and contact patterns of 105 saliva swallows (45 with NSOMD, 60 without NSOMD) were analyzed by compartmentalizing the sensor display and tracking the …

An 8-month-old crossbred ewe, normal upon physical examination, was humanely euthanized for tissue collection. After approximately 3 weeks in tissue culture, fungi began budding out of cells obtained from the choroid plexus. After an additional 3 weeks, budding was observed in kidney cell cultures and eventually in monocyte cultures as well. Serum from the lamb was submitted to the Veterinary Diagnostic Laboratory at Colorado State University for fungal diagnosis and was found negative for Aspergillus, Blastomyces, Coccidioidomycosis and Histoplasmosis. DNA was isolated from fungi collected from tissue culture supernatants and used in a set of pan-fungal PCR assays with …

Interferon Inducible Protein Ifi35 Negatively Regulates Rig-I Antiviral Signaling And Supports Vesicular Stomatitis Virus Replication, Anshuman Das, Phat X. Dinh, Debasis Panda, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

In a genome-wide siRNA screen, we recently identified the interferon (IFN) inducible protein 35 (IFI35, also known as IFP35) as a factor required for VSV infection. Studies reported here were conducted to further understand the role and requirement of IFI35 in VSV infection. Consistent with the siRNA screening data, we found that depletion of IFI35 led to reduced VSV replication at the level of viral gene expression. Although no direct interaction of IFI35 with the viral replication machinery was observed, we found that IFI35 negatively regulated the host innate immune response and rescued poly(I:C)-induced inhibition of VSV replication. Promoter-driven reporter …

Sequence-Optimized And Targeted Double-Stranded Rna As A Therapeutic Antiviral Treatment Against Infectious Myonecrosis Virus In Litopenaeus Vannamei, J. Dustin Loy, Duan S. Loy, Mark A. Mogler, Bruce Janke, Kurt Kamrud, D. L. Hank Harris, Lyric C. Bartholomay

School of Veterinary and Biomedical Sciences: Faculty Publications

Infectious myonecrosis virus (IMNV) is a significant and emerging pathogen that has a tremendous impact on the culture of the Pacific white shrimp Litopenaeus vannamei. IMNV first emerged in Brazil in 2002 and subsequently spread to Indonesia, causing large economic losses in both countries. No existing therapeutic treatments or effective interventions currently exist for IMNV. RNA interference (RNAi) is an effective technique for preventing viral disease in shrimp. Here, we describe the efficacy of a double-stranded RNA (dsRNA) applied as an antiviral therapeutic following virus challenge. The antiviral molecule is an optimized dsRNA construct that targets an IMNV sequence …

Bovine Herpes Virus 1 (Bhv-1) And Herpes Simplex Virus Type 1 (Hsv-1) Promote Survival Of Latently Infected Sensory Neurons, In Part By Inhibiting Apoptosis, Clinton Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

α-Herpesvirinae subfamily members, including herpes simplex virus type 1 (HSV-1) and bovine herpes virus 1 (BHV-1), initiate infection in mucosal surfaces. BHV-1 and HSV-1 enter sensory neurons by cell-cell spread where a burst of viral gene expression occurs. When compared to non-neuronal cells, viral gene expression is quickly extinguished in sensory neurons resulting in neuronal survival and latency. The HSV-1 latency associated transcript (LAT), which is abundantly expressed in latently infected neurons, inhibits apoptosis, viral transcription, and productive infection, and directly or indirectly enhances reactivation from latency in small animal models. Three anti-apoptosis genes can be substituted for LAT, which …

Relevance Of Molecular Mimicry In The Mediation Of Infectious Myocarditis, Chandirasegaran Massilamany, Sally A. Huber, Madeleine W. Cunningham, Jay Reddy

Jay Reddy Publications

Heart disease, the leading cause of death in humans, is estimated to affect one in four American adults in some form. One predominant cause of heart failure in young adults is myocarditis, which can lead to the development of dilated cardiomyopathy, a major indication for heart transplantation. Environmental microbes, including viruses, bacteria, and fungi that are otherwise innocuous, have the potential to induce inflammatory heart disease. As the list is growing, it is critical to determine the mechanisms by which microbes can trigger heart autoimmunity and, importantly, to identify their target antigens. This is especially true as microbes showing structural …
