ATCA (2-amino-2-thiazoline-4-carboxylic acid) is a promising marker to assess cyanide exposure because of several advantages of ATCA analysis over direct determination of cyanide and alternative cyanide biomarkers (i.e. stability in biological matrices, consistent recovery, and relatively small endogenous concentrations). Concentrations of ATCA in the plasma of smoking and non-smoking human volunteers were analyzed using gaschromatography mass-spectrometry to establish the feasibility of using ATCA as a marker for cyanide exposure. The levels of ATCA in plasma of smoking volunteers, 17.2 ng/ml, were found to be significantly (p < 0.001) higher than that of non-smoking volunteers, 11.8 ng/ml. Comparison of ATCA concentrations of smokers relative to nonsmokers in both urine and plasma yielded relatively similar results. The concentration ratio of ATCA for smokers versus non-smokers in plasma and urine was compared to similar literature studies of cyanide and thiocyanate, and correlations are discussed. This study supports previous evidence that ATCA can be used to determine past cyanide exposure and indicates that further studies should be pursued to validate the use of ATCA as a marker of cyanide exposure.

Percent calf crop weaned is influenced more by man¬agement decisions than by any other single factor in a cow herd, and therefore can be a very important factor in annual returns for a cow-calf operation. Percent calf crop weaned is calculated by dividing the number of calves weaned by the total number of females exposed during the breeding season. As shown in Table 1, as percent calf crop weaned increases, pounds of calf weaned per cow exposed increas¬es and production cost per hundred pounds of calf produced decreases. Increasing weaning weights approximately 50 pounds is equal to an increase of …

El azufre es un elemento esencial que los animales necesitan para muchas funciones. Cerca del 0.15% del peso corporal es azufre. Se encuentra en los aminoácidos metioni¬na, cisteína, cistina, homocisteína y taurina; en el condroi¬tin sulfato del cartílago y en las vitaminas del complejo B tiamina y biotina. La metionina, tiamina y biotina no pueden sintetizarse en los tejidos del ganado, deben por lo tanto ser suministradas con la dieta o sintetizadas por los microorgan¬ismos del rumen. El contenido en azufre de la mayor parte de los alimentos refleja el contenido en aminoácidos azufrados de sus proteínas. En la tabla …

Range Management And Soil Seed Bank: New Perspective, Lan Xu, Brent E. Turnipseed, Roger N. Gates, Patricia Johnson, Nels H. Troelstrup Jr.
Oak Lake Field Station Research Publications
Seed banks are considered essential constituents of plant communities and contribute significantly to ecological processes. Seed banks play a critical role in managing the composition and structure of existing vegetation, restoring native vegetation, creating habitat for animals, preserving genetic diversity, and recovering endangered plant species. Therefore, implementation of management practices based only on existing aboveground vegetation, without the information of soil seed flora is obviously incomplete and dangerous. Our objectives were to determine effects of prescribed burning and reseeding managements on soil seed bank composition and the relationship between the soil seed bank and aboveground vegetation. The study was conducted …

Dairy Science Publication Database
El periodo de transición en la vaca lechera se caracteriza por una disminución del consumo de alimento que comienza unos días antes del parto y que recién se recupera varios días después del mismo. Esta caída en la cantidad de alimento ingerido resulta en un desbalance entre los requerimientos nutricionales y los nutrientes absorbidos luego de la ingesta. Existen otros factores relacionados con el volumen y la forma física del alimento que pueden llevar a otros trastornos frecuentes del peri-parto. Por lo general el diagnóstico veterinario se basa en la manifestación clínica de una determinada afección. Para tener un mayor …

Jeff Koons: In His Space, Erica Frank
Jeff Koons: In His Space, Erica Frank
The Journal of Undergraduate Research
Space, a major visual element, can be examined in depth in Jeff Koons’s artwork. Koons produces art in different series and each series contains numerous pieces. The appendages of the mechanical devices, a major element of space in the early series, accentuate the sexuality present in Koons’s art, as well as the surface quality and materials used in all the series. Koons’s obsession with perfection is what generates the flawless exteriors making the surface material void of human touch and elevating the sometimes kitsch subjects of the pieces. Koons uses stainless steel, a relatively inexpensive material associated with manufactured goods …
Effects Of Stratification, Warm Treatment, And Mechanical And Acid Scarification On The Emergence Of Yellow-Flowered Alfalfa (Medicago Sativa Subsp. Falcata) Seeds, Diane Narem
The Journal of Undergraduate Research
Yellow-flowered alfalfa (YFA) has great potential to improve rangelands in the Northern Plains. Greater than 99% of YFA seeds from soil were viable but less than 4% germinated under standard laboratory conditions. The objective was to determine if low germination was due to physical or physiological seed dormancy. The experiment utilized a random complete block design with two trials, eight replications per trial. Each replication consisted of ten treatments plus a control, four stratification treatments consisting of a combination of two temperatures (-5°C, -20°C) and two durations (48 hr, 72 hr), one warm treatment (4 min, 60°C), four sandpaper scarification …

Sustainability Efforts At South Dakota State University, Joshua A. Schuttloffel
The Journal of Undergraduate Research
South Dakota State University wants to develop a sustainable environment. However, the University has, thus far, refused to make a formal commitment to sustainability. This paper examines how the ecology, communication networks, politic decisions, and issue networks of the University have influenced the University administration to have a goal towards sustainability yet refuse formal commitments to improving the sustainability of the University. Interviews with individuals intimately involved with issues of sustainability at the University are used to present a case study of events from the time sustainability became a goal of University to current. Public administration theory is used to …

The treatment of viral diseases remains an intractable problem facing the medical community. Conventional antivirals focus upon selective targeting of virus-encoded targets. However, the plasticity of viral nucleic acid mutation, coupled with the large number of progeny that can emerge from a single infected cells, often conspire to render conventional antivirals ineffective as resistant variants emerge. Compounding this, new viral pathogens are increasingly recognized and it is highly improbable that conventional approaches could address emerging pathogens in a timely manner. Our laboratories have adopted an orthogonal approach to combat viral disease: Target the host to deny the pathogen the ability …

Planted Grasslands And Native Sod Prairie: Equivalent Habitat For Grassland Birds, Kristel K. Bakker, Kenneth F. Higgins
Natural Resource Management Faculty Publications
Little is known about how avian relationships to tracts of native sod prairie compare with avian relationships to single and multiple species of cool- and warm-season grassland plantings. We compared grassland bird species richness and density in 5 grassland cover types (n = 97) in the tallgrass prairie region of eastern South Dakota and western Minnesota, 2001–2004. Grassland bird species richness was significantly higher in native sod prairies than it was in all planted cover types except warm-season mixes. Grasslands dominated by exotic species did not support as many grassland bird species or have species densities as high as grasslands …

Natural Resource Management Faculty Publications
Carbon (δ13C) and nitrogen (δ15N) isotopes in biological samples from large herbivores identify photosynthetic pathways (C3 vs. C4 ) of plants they consumed and can elucidate potential nutritional characteristics of dietary selection. Because large herbivores consume a diversity of forage types, δ13C and δ15N in their tissue can index ingested and assimilated diets through time. We assessed δ13C and δ15N in metabolically active liver tissue of sympatric mule deer (Odocoileus hemionus) and white-tailed deer (O. virginianus) to identify dietary disparity resulting from use of burned and unburned areas in a largely forested landscape. Interspecific variation in dietary disparity of deer …

Natural Resource Management Faculty Publications
A feeding trial was performed to investigate levels of corn-based Distillers Dried Grains with solubles (DDGS), a co-product of fuel ethanol manufacturing, used as a nutrient source for juvenile Nile tilapia (Oreochromis niloticus). Three isocaloric (15.7±0.7 MJ kg-1 dry matter), isonitrogenous (29.6±1.0% crude protein) experimental diets were formulated to contain 20, 30 and 40% DDGS; a commercial diet containing fishmeal was used as a reference diet. Glass aquaria (110 L) were stocked with Nile tilapia (mean weight = 6.7 g) with four replicates per diet. Weight gains, conversion ratios and hepatosomatic indices did not significantly differ between …

Monitoring Calcium, Phosphorous, And Vitamin D₃ Deficiencies In Starter, Growing, And Finishing Pigs, Chris Hostetler, Bob Thaler
SDSU Extension Extra Archives
Due to the increasing cost of dietary ingredients, many swine producers are looking for the most cost-effective ways to meet the nutritional needs of their animals. One of the most costly ingredients in swine diets is inorganic phosphorus, which is normally supple¬mented as dicalcium phosphate. Calcium, phosphorus, and vitamin D3 each play a major role in bone formation, and a deficiency in these nutrients can lead to depressed growth, rickets, broken bones, and, eventually, paralysis in the hind legs. A lesser-known symptom of calcium/phosphorus/vitamin D3 deficiency is the formation of large nodules, called rachitic rosaries, on the ribs of market …
Preventative Feeding Of The Dairy Cow In Transition, Alvaro Garcia, Arnold Hippen
Preventative Feeding Of The Dairy Cow In Transition, Alvaro Garcia, Arnold Hippen
SDSU Extension Extra Archives
The transition period in the lactating dairy cow is characterized by decreased feed intake that starts late in the close-up period and recovers several days after calving. This drop in intake results in an imbalance between required and absorbed nutrients. Other factors that are related to the volume and physical form of the feed can lead to problems frequently observed at calving time. In general, the veterinary diagnosis is based upon clinical symptoms of certain ailments. For greater chances of success and decreased treatment costs, it’s necessary to detect these ailments during their subclinical stage, or, better yet, to prevent …

Growing And Direct Marketing Produce: Potential Hazards, Joan Hegerfeld-Baker
SDSU Extension Extra Archives
Providing a safe food to the consumer requires a process that incorporates food safety from planting to harvesting. Fruit and vegetables growers that market locally are con¬fronted with the same food safety concerns as produce operations that distribute statewide, nationally, or even globally. Growers must first identify the potential food safety hazards related to their operation. Once the hazards are identified, a plan that addresses safe food handling must be implemented.

The susceptibility of wild ruminants, especially cervids, to bovine viral diarrhea virus (BVDV) has remained an enigma. Two white-tailed deer (Odocoileus virginianus) were submitted to the Animal Disease Research and Diagnostic Laboratory (ADRDL) in the fall of 2003 by the South Dakota Game Fish and Parks for chronic wasting disease (CWD) testing. Both animals were CWD negative. The animals were necropsied and histopathology, viral antigen detection, and virus isolation were performed. A noncytopathic (NCP) BVDV was isolated from the lungs and several other tissues of both animals. Formalin-fixed ear notches from both animals were positive for BVDV antigen by immunohistochemistry. …
