Department of Biochemistry: Faculty Publications
Proline dehydrogenase catalyzes the FAD-dependent oxidation of proline to Δ1- pyrroline-5- carboxylate, which is the first step of proline catabolism. Here, we report the structures of proline dehydrogenase from Deinococcus radiodurans in the oxidized state complexed with the proline analog L-tetrahydrofuroic acid and in the reduced state with the proline site vacant. The analog binds against the si face of the FAD isoalloxazine and is protected from bulk solvent by the α8 helix and the β1-α1 loop. The FAD ribityl chain adopts two conformations in the E-S complex, which is unprecedented for flavoenzymes. One of the conformations is novel for …

Characterization Of Chemotype And Aggressiveness Of Nebraska Isolates Of Fusarium Graminearum, Anita Panthi
Characterization Of Chemotype And Aggressiveness Of Nebraska Isolates Of Fusarium Graminearum, Anita Panthi
Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship
Fusarium head blight (FHB), caused mainly by Fusarium graminearum, is a devastating disease of wheat and other small grain cereals. FHB lowers grain yield and quality and contaminates grain with mycotoxins, predominantly deoxynivalenol (DON) and its acetylated derivatives 3-ADON and 15-ADON. Forty one Fusarium isolates collected from grain elevators and wheat fields in Nebraska in 2009 and 2010 were sequenced for molecular identification. Forty isolates were identified as F. graminearum and one isolate was identified as F. culmorum. Seventy seven F. graminearum isolates collected from grain elevators and wheat fields in Nebraska from 2007 to 2010 were tested …

Characterization Of Starch By Vibrational Spectroscopy, Brandon H. Holder
Characterization Of Starch By Vibrational Spectroscopy, Brandon H. Holder
Department of Food Science and Technology: Dissertations, Theses, and Student Research
To develop a dispersive Raman spectroscopic method for measuring amylose-amylopectin ratios of corn starch mixtures, 67 mixtures were prepared by randomly mixing waxy and normal corn starches. Amylose contents were measured using a dual wavelength iodine binding colorimetric method. Raman data were collected from 250 to 3200 cm-1 using optimized instrument parameters. Partial least-squares (PLS) and principal components regression (PCR) were used to prepare multivariate calibration models; however, PLS commonly outperformed PCR. Truncating the spectra to 250 to 2000 cm-1 improved the results (r2 of validation = 0.831, SEP = 2.90%). Removal of a cold water swelling …
Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
Interactions Of Zooplankton And Phytoplankton With Cyanobacteria, Rebecca Alexander
School of Natural Resources: Dissertations, Theses, and Student Research
Cyanobacteria are a major concern in Nebraska reservoirs and are capable of producing toxins that can cause skin irritations and gastrointestinal problems, as well as affect the nervous system. It is important to determine the mechanisms that can cause cyanobacteria blooms due to the effect they can have on human health. The interaction of zooplankton and other phytoplankton groups with cyanobacteria is important because there is a biological component in surface waters that should be taken into consideration along with the physical and chemical parameters that have been noted to promote cyanobacteria. For example, zooplankton have the ability to alter …
Population Characteristics, Development Of A Predictive Population Viability Model, And Catch Dynamics For Pallid Sturgeon In The Lower Missouri River, Kirk D. Steffensen
Population Characteristics, Development Of A Predictive Population Viability Model, And Catch Dynamics For Pallid Sturgeon In The Lower Missouri River, Kirk D. Steffensen
School of Natural Resources: Dissertations, Theses, and Student Research
Population characteristics and long-term population trends of pallid sturgeon Scaphirhynchus albus in the lower Missouri River are relatively unknown. As recovery efforts continue, understanding and quantifying these characteristics and trends are critical for species recovery and future management decisions. Therefore, the objectives of this study were to determine the pallid sturgeon population characteristics, predict changes to the pallid sturgeon population based on different management and life history scenarios, and examine trot line catch dynamics in the lower Missouri River. Catch rates for pallid sturgeon collected with gill nets did not significantly change while catch rates using trot lines significantly declined …

Glutaredoxin 2 (Grx2) Knockout Increases Sensitivity To Oxidative Stress In Mouse Lens Epithelial Cells, Hongli Wu, Liren Lin, Frank Giblin, Ye-Sheh Ho, Marjorie F. Lou
School of Veterinary and Biomedical Sciences: Faculty Publications
Glutaredoxin belongs to the oxidoreductase family with cytosolic glutaredoxin 1 (Grx1) and mitochondrial gluraredoxin 2 (Grx2) isoforms. Of the two isozymes, the function of Grx2 is not well understood. This paper studied the effect of Grx2 deletion on cellular function using primary lens epithelial cell cultures isolated from Grx2 gene knockout (KO) and wild type (WT) mice. We found that both cell types showed similar growth patterns and morphology, and comparable mitochondrial glutathione pool and complex I activity. Cells with deleted Grx2 did not show affected Grx1 or thioredoxin (Trx) expression but exhibited high sensitivity to oxidative stress. Under treatment …

Object. Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential shortand long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions.
Methods. Players on 3 college …

Notes On A Greater Sage-Grouse Record By Levi L. Mohler, Mark A. Brogie
Notes On A Greater Sage-Grouse Record By Levi L. Mohler, Mark A. Brogie
Nebraska Bird Review
In Nebraska, Greater Sage-Grouse has been considered an uncommon casual winter visitor in the extreme northwest (Sharpe et al. 2001). This species may now be extirpated in Nebraska due to habitat loss. There have been no known Nebraska observations of Greater Sage-Grouse in the last 25 years. The only documented record accepted by the NOURC of Greater Sage-Grouse in Nebraska (Accession #243) is a description of an adult male in September 1987 in extreme northwest Sioux County by Douglas Kapke (Grenon AG. 1990).
In 2002 Wayne Mollhoff received the following record from Levi L. Mohler and submitted it to the …
Nitrous Oxide Emissions From Smooth Bromegrass Pasture Under Nitrogen Fertilizer And Ruminant Urine Application In Eastern Nebraska, Laura K. Snell
Nitrous Oxide Emissions From Smooth Bromegrass Pasture Under Nitrogen Fertilizer And Ruminant Urine Application In Eastern Nebraska, Laura K. Snell
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Nitrous oxide (N2O) is a greenhouse gas primarily produced in soils by denitrifying and nitrifying organisms. Agricultural soils account for 70% of emissions in the United States, but little data is available for contributions from managed pasture ecosystems. This study focused on the production of N2O in smooth bromegrass (Bromus inermis Leyss.) pastures established on silt loam soils in eastern Nebraska. Thirty smooth bromegrass plots (1.5m x 1.5m) were treated with five different fertilizer treatments (0, 45, 90, 135, and 180 kg N/ha) and two urine treatments (urine and no urine). Herbage sampling was taken …

Fall Field Report, August–November 2012, W. Ross Silcock
Nebraska Bird Review
Some of you may be curious about the sources of sightings I use to compile these reports. The primary sources are reports posted to NEBirds, the Nebraska Listserv, along with the full reports (early and late dates, peak counts for all species) sent by a few faithful reporters around the state. The latter reports are very useful overviews of movements in the reporters' regions. Lately, thanks to a suggestion by Clem Klaphake, I have been receiving the eBird daily rarity report for Nebraska which I find to be an excellent check against reports posted to NEBirds, while providing a few …

Differential Surface Deposition Of Complement Proteins On Logarithmic And Stationary Phase Leishmania Chagasi Promastigotes, Amanda Ramer-Tait, Soi Meng Lei, Bryan H. Bellaire, Jeffrey K. Beetham
Differential Surface Deposition Of Complement Proteins On Logarithmic And Stationary Phase Leishmania Chagasi Promastigotes, Amanda Ramer-Tait, Soi Meng Lei, Bryan H. Bellaire, Jeffrey K. Beetham
Department of Food Science and Technology: Faculty Publications
Previous works demonstrated that various species of Leishmania promastigotes exhibit differential sensitivity to complement-mediated lysis (CML) during development. Upon exposure to normal human serum (NHS), cultures of Leishmania chagasi promastigotes recently isolated from infected hamsters (fewer than 5 in vitro passages) are CML-sensitive when in the logarithmic growth phase but become CML-resistant upon transition to the stationary culture phase. Visualization by light and electron microscopy revealed dramatic morphological differences between promastigotes from the 2 culture phases following exposure to NHS. Flow cytometric analysis demonstrated that surface deposition of the complement components C3, C5, and C9 correlated inversely with promastigote CML-resistance. …

Department of Biochemistry: Faculty Publications
Evidence suggests that selenium has cancer preventive properties that are largely mediated through selenoproteins. Our previous observations demonstrated that targeted down-regulation of the 15 kDa selenoprotein (Sep15) in murine colon cancer cells resulted in the reversal of the cancer phenotype. The present study investigated the effect of Sep15 knockout in mice using a chemically-induced colon cancer model. Homozygous Sep15 knockout mice, and wild type littermate controls were given four weekly subcutaneous injections of azoxymethane (10 mg/kg). Sep15 knockout mice developed significantly (pGBP-1 in humans has been associated with a highly significant, increased five-year survival rate in colorectal cancer patients. In …

Investigations On Rangeland Grasshoppers: Ecoregion Level Distribution, Identification, Feeding Performance, And Vegetation Clipping, Muhammad Ullah
Department of Entomology: Dissertations, Theses, and Student Research
Short-horned grasshoppers (Orthoptera: Acrididae) were studied in the field as well as in laboratory for their distribution, identification, preferred food plants and feeding damage. These grasshoppers are important potential pests of rangelands where they compete for forage with cattle. Examination of the 20 most common grasshoppers by levels 3 and 4 of Nebraska ecoregions revealed specific habitat use and may be helpful in predicting hotspots. The relative abundance of all species analyzed showed at least some significant differences at ecoregion level 4 and two species showed single ecoregion that differed from all others at level 3.
Grasshoppers belonging to subfamilies …

Fish Assemblage Structure In Black Hills, South Dakota Streams, Luke D. Schultz, Sarah J. Lewis, Katie Nicole Bertrand
Fish Assemblage Structure In Black Hills, South Dakota Streams, Luke D. Schultz, Sarah J. Lewis, Katie Nicole Bertrand
The Prairie Naturalist
Understanding factors structuring fish assemblages in a particular area is valuable to both sport fishery management and native species conservation. Fish assemblages in the Black Hills are unique to South Dakota because they contain economically valuable introduced salmonids as well as native species of conservation need. Our objective was to examine the relationship between fish assemblages and geomorphic and reach-scale habitat features across multiple stream reaches in the Black Hills. Canonical correspondence analysis, a direct gradient ordination analysis, indicated that factors operating at multiple spatial scales interacted to structure fish assemblages. There also was indication of segregation between native species …
Terrestrial And Semi-Aquatic Vertebrates In Diets Of Largemouth Bass In Central Nebraska, Seth A. Lundgren, Keith Geluso, Casey W. Schoenebeck
Terrestrial And Semi-Aquatic Vertebrates In Diets Of Largemouth Bass In Central Nebraska, Seth A. Lundgren, Keith Geluso, Casey W. Schoenebeck
The Prairie Naturalist
Largemouth bass (Micropterus salmoides) are opportunistic predators often feeding in littoral areas during crepuscular periods (Snow 1971). Adult largemouth bass primarily are piscivorous, whereas juveniles generally consume zooplankton, insects, and small fish (Zweiacker and Summerfelt 1974, Carlander 1977, Post 2003). Age-0 largemouth bass generally consume zooplankton and macroinvertebrates (Keast and Webb 1966, Keast 1985, Phillips et al. 1995, Post 2003) and shift to piscivory at 50-70 mm in length (Phillips et al. 1995, Olson 1996, Post 2003). Few studies have documented detailed accounts of other vertebrates besides fish in diets of largemouth bass, which include amphibians (Hodgson and …
