Compartmentalization Of The Broad-Range Phospholipase C Activity To The Spreading Vacuole Is Critical For Listeria Monocytogenes Virulence, P.S. Marie Yeung, Yoojin Na, Amanda J. Kreuder, Helene Marquis
Compartmentalization Of The Broad-Range Phospholipase C Activity To The Spreading Vacuole Is Critical For Listeria Monocytogenes Virulence, P.S. Marie Yeung, Yoojin Na, Amanda J. Kreuder, Helene Marquis
Biological Sciences
Listeria monocytogenes is a bacterial pathogen that multipliesin the cytosol of host cells and spreads directly from cellto cell by using an actin-based mechanism of motility. The broad-rangephospholipase C (PC-PLC) of L. monocytogenes contributes tobacterial escape from vacuoles formed upon cell-to-cell spread.PC-PLC is made as an inactive proenzyme whose activation requirescleavage of an N-terminal propeptide. During infection, PC-PLCis activated specifically in acidified vacuoles. To assess theimportance of compartmentalizing PC-PLC activity during infection,we created a mutant that makes constitutively active PC-PLC(the plcBpro mutant). Results from intracellular growth andcell-to-cell spread assays showed that the plcBpro mutant wassensitive to gentamicin, suggesting …

Correlated Evolution Of Genome Size And Seed Mass, Jeremy M. Beaulieu, Angela T. Moles, Ilia J. Leitch, Michael D. Bennett, John B. Dickie, Charles A. Knight
Biological Sciences
• Previous investigators have identified strong positive relationships between genome size and seed mass within species, and across species from the same genus and family. • Here, we make the first broad-scale quantification of this relationship, using data for 1222 species, from 139 families and 48 orders. We analyzed the relationship between genome size and seed mass using a statistical framework that included four different tests. • A quadratic relationship between genome size and seed mass appeared to be driven by the large genome/seed mass gymnosperms and the many small genome size/large seed mass angiosperms. Very small seeds were never …
Trypanosome Infection In Cattle And African Sleeping Sickness, Susann O. Smith
Trypanosome Infection In Cattle And African Sleeping Sickness, Susann O. Smith
International Journal of Global Health and Health Disparities
Trypanosomes are inoculated into a host (human or animal) in saliva via the biting mouth parts of the tsetse fly. Trypanosomes circulate in the blood of their host, differentiate and spread to other tissues via the lymphatic system during a 30 day period. Humans with African Sleeping Sickness or Human African Trypanosomiasis (HAT) complain of having a fever, headaches and joint pain. If left untreated, a neurological phase develops causing confusion, fatigue, narcolepsy like symptoms, irreversible nerve damage and eventual death. Often associated with malnutrition and poverty, HAT has been reported to have been in existence in Africa since the …
Consequences Of A Genetic Bottleneck In California Condors: A Mitochondrial Dna Perspective, Mary S. Adams, Francis X. Villablanca
Consequences Of A Genetic Bottleneck In California Condors: A Mitochondrial Dna Perspective, Mary S. Adams, Francis X. Villablanca
Biological Sciences
The California Condor (Gymnogyps californianus) has recently survived a severe population bottleneck. The entire population was reduced to 27 individuals in 1982. The number of genetic founders was even smaller. We obtained 482 base pairs of DNA sequence from the mitochondrial control region (CR) of all founder individuals that potentially represented unique maternal haplotypes. Four unique haplotypes were present in the genetic founders. One of these haplotypes is unique to Topatopa, a male brought into captivity in 1967, whose haplotype will not persist in the future population. Haplotype diversity (h) was reduced by 25% between the founder population …

Evaluation Of A Tissue Culture-Based Approach For Differentiating Between Virulent And Avirulent Vibrio Parahaemolyticus Strains Based On Cytotoxicity, P.S. Marie Yeung, Martin Wiedmann, Kathryn J. Boor
Evaluation Of A Tissue Culture-Based Approach For Differentiating Between Virulent And Avirulent Vibrio Parahaemolyticus Strains Based On Cytotoxicity, P.S. Marie Yeung, Martin Wiedmann, Kathryn J. Boor
Biological Sciences
The ability of only a subset of Vibrio parahaemolyticus strains to cause human infection underscores the need for an analytical method that can effectively differentiate between pathogenic strains and those that do not cause disease. We tested the feasibility of a tissue culture-based assay to determine whether clinical isolates could be differentiated from nonclinical isolates based on relative isolate cytopathogenicity. To screen for cytotoxic capability, we measured relative extracellular lactate dehydrogenase as an indicator of host cell damage in five different mammalian cell lines in the presence of V. parahaemolyticus. Isolates originating from clinical sources exhibited 15.5 to 59.3% …

Effects Of Increasing The Energy Density Of A Lactating Ewe Diet By Replacing Grass Hay With Soybean Hulls And Dried Distillers Grains With Solubles, Aimee Wertz-Lutz, Robert Zelinsky, Jeffrey Held
Effects Of Increasing The Energy Density Of A Lactating Ewe Diet By Replacing Grass Hay With Soybean Hulls And Dried Distillers Grains With Solubles, Aimee Wertz-Lutz, Robert Zelinsky, Jeffrey Held
South Dakota Sheep Research Reports, 2006-07
The objective of this experiment was to determine the effects of increasing the energy density of a lactating ewe diet by replacing grass hay (GH) with soybean hulls (SH) and replacing soybean meal (SBM) with dried distillers grains with solubles (DDGS) on ewe body condition, milk production and nutrient composition, and lamb performance. Sixteen 2-year-old ewes were selected based on a common lambing date. All diets contained 60% roughage and 40% concentrate. Dietary roughage source, however varied from completely GH to completely SH, and SBM was replaced by DDGS. Diets were formulated to contain 13.9% CP and an increasing amount …

Pasture Lease Agreements, Burton Pflueger
SDSU Extension Extra Archives
Any lease is basically an agreement that gives the use of an asset to a lessee for a specific period of time at a specified rate. A lease does not transfer title of ownership nor an equity interest in the asset. Labeling a document as a lease does not necessarily mean it is a lease according to the Internal Revenue Service (IRS). This Extension Extra does not address any of the questions concerning the IRS treatment of a lease; if you have such questions, contact your tax management professional. Also, this document does not address any of the questions concerning …

Utah Prairie Dog Habitat Evaluation Guide, Natural Resources Conservation Service, Environmental Defense
All U.S. Government Documents (Utah Regional Depository)
The Utah prairie dog (Cynomys parvidens) (UPD) is listed as a threatened species under the Endangered Species Act (ESA) and exists only in southwestern Utah. UPD numbers and range have declined dramatically since settlement of Utah because of conversion of rangeland to cropland, urban development, fire suppression, improper grazing, drought, and introduced sylvatic plague (Yersina pestis). As of this writing, approximately 75% of all Utah prairie dogs inhabit private lands. This fact highlights the need to encourage farmers and ranchers to manage UPD habitat on their property in order to move the species closer to recovery. This guide provides technical …
Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers
Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers
All U.S. Government Documents (Utah Regional Depository)
In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen’s epiphytic lichen …

In today’s global marketplace, the volume of international trade brings increased potential for the introduction of foreign pests, diseases, and noxious weeds that could threaten the safety of American agriculture. The results of such introductions can have a devastating effect on the U.S. food supply, damage our natural resources, and cost hundreds of millions of dollars in eradication and control measures that ultimately result in higher priced agricultural products for the consumer.

Frankenstein: Man Or Monster?, Leigh P. Mackintosh
Frankenstein: Man Or Monster?, Leigh P. Mackintosh
Undergraduate Theses and Capstone Projects
Since its first publication in 1818, Mary Shelley’s novel Frankenstein has left a lasting impression upon the world speaking to a multitude of audiences including artists, scientists, philosophers, and society as a whole. Considering the impact of Frankenstein through its evolution as a cultural myth in various plays and films, this thesis will provide a way to gauge the relevance of Shelley’s story as an adaptation. Only by knowing what has been done in the past and how the materials have been used by other playwrights and screenwriters can one understand how to handle them as an original work. The …

The R.F.I.D. Act Of 2006 And E-Pedigrees: Tackling The Problem Of Counterfeit Drugs In The United States Wholesale Industry, Suchira Ghosh
Michigan Telecommunications & Technology Law Review
Gaps within the drug distribution system make it increasingly vulnerable to bad actors, such as counterfeiters and terrorists. Congress intended the Prescription Drug Marketing Act (PDMA) of 1987 to close these gaps, but the PDMA has not fully succeeded. Important PDMA provisions that require tracking of drugs throughout the distribution chain in the form of "pedigrees" were set to be implemented as of Dec. 1, 2006, although a recent court order has stayed complete implementation. However, these PDMA requirements do not apply uniformly to all drug distributors in the United States. Moreover, since paper pedigrees can be forged, the pedigree …
Pharmaceutical Lemons: Innovation And Regulation In The Drug Industry, Ariel Katz
Pharmaceutical Lemons: Innovation And Regulation In The Drug Industry, Ariel Katz
Michigan Telecommunications & Technology Law Review
Before a new drug can be marketed, the Food and Drug Administration must be satisfied that it is safe and effective. According to conventional wisdom, the cost and delay involved in this process diminish the incentives to invest in the development of new drugs. Accordingly, several reforms aimed at restoring such incentives have been implemented or advocated. This Article challenges the central argument that drug regulation and drug innovation are necessarily at odds with one another. Although intuitively appealing, the argument that drug regulation negatively affects the incentives to innovate does not fully capture the role that regulation plays in …

A Taxonomic Investigation Of The Black Ratsnake, Elaphe O. Obsoleta (Say) [Reptilia, Squamata, Colubridae], In West Virginia Using Morphometric Analyses, Adam M. Mann
Theses, Dissertations and Capstones
A recent genetic study by Frank T. Burbrink (2000) determined that the common Black Ratsnake, Elaphe o. obsoleta, evolved from three separate evolutionary lineages and can no longer be classified under a single species name. The newly assigned species, which possess ranges that are separated into three regions of the eastern United States by geologic features such as rivers and mountains, are also said to possess distinct morphologic characteristics (Burbrink, 2001). This thesis study was initiated to mirror Burbrink’s previous morphometric study and augment a previous lack of specimen data from West Virginia. Black Ratsnake museum specimens, collected from ranges …
