The University of Dubuque is a Presbyterian university located in Dubuque, in the U.S. state of Iowa, with a general attendance of approximately 1,600 students. The school offers both undergraduate and graduate degree programs. It is one of three four-year post-secondary institutions in the City of Dubuque, and is commonly referred to as UD . The Greek system is historically present. Wikipedia.

This paper examines the AIDS Coalition to Unleash Power (ACT UP), a non-governmental organization within the larger HIV/AIDS movement. ACT UP is examined through the lens of new social movement network theory (Atkinson, 2009). Using constitutive rhetoric (Charland, 1987), the narrative capacities of the rhetorical strategies that appear to be embodied on ACT UP's Web site are reviewed. The impact that ACT UP has on health and social policy globally has wide reaching ramifications, making the current investigation into its rhetorical strategies viable and important. The findings suggest ACT UP employs constitutive rhetoric to affect a viable narrative capacity in its network. Source

This biodiesel lab experiment increased the student's understanding of biofuels and associated chemical concepts. The flash point testing proved to be a constructive activity to relate vapor pressure properties of biodiesel and other fuels to their chemical structure. Comparison of student-produced biodiesel with that obtained from a commercial supplier illustrated how fuel properties depend on the production process and the resulting composition and purity of the fuel product. The contrast between density and flash point testing also demonstrated the reason why multiple QA-QC tests are necessary for fuels. The fact that the crude biodiesel produced by students did not conform to ASTM standards was a good lesson in QA-QC and provided students with insight to the rules and processes concerning industrial chemical production and commercial regulation. © 2010 American Chemical Society and Division of Chemical Education, Inc.

Key message: TrimericGalanthus nivalisagglutinin-related lectin of Orchidaceae with two conformational forms was first studied inDendrobium pendulum. It was highly expressed by stress factors. Abstract: Using mannan–agarose column chromatography, a mannose-binding protein was purified from Dendrobiumpendulum Roxb. pseudobulb. After heating in the presence of sodium dodecyl sulfate (SDS) with or without 2-mercaptoethanol, the protein showed one band with molecular mass of 14.0 kDa on SDS-polyacrylamide gel electrophoresis (PAGE). Without heating, three bands were found at positions of 14.0, 39.4, and 41.5 kDa, but a higher amount of 39.4 and 41.5 kDa protein bands were seen in the presence of 2-mercaptoethanol. Liquid chromatography–tandem mass spectrometry and database search indicated that the 14.0 kDa protein band contained three peptide fragments identical to parts of a lectin precursor from Dendrobium findleyanum Parish & Rchb.f. Native-PAGE and Ferguson plot showed that the purified protein had two native forms with molecular masses of 44.2 and 45.3 kDa, indicating three 14.0 kDa polypeptide subunits. The purified protein exhibited the agglutination activity with trypsinized chicken erythrocytes. It was then recognized as a Galanthus nivalis agglutinin-related lectin and named D. pendulum agglutinin (DPA). Using reverse transcription-polymerase chain reaction and DNA sequencing, the deduced amino acid sequence of DPA precursor showed the highest homology (96.4 %) with a lectin precursor of D. findleyanum and contained three mannose-binding sites. Greater amounts of DPA were found when the pseudobulbs were treated with stress factors including ultraviolet light, abscisic acid, hydrogen peroxide, and acetylene gas. © 2015, Springer-Verlag Berlin Heidelberg.

The objective of this study was to evaluate the type of alcohol policy in place in 4-year public universities against the odds of heavy drinking. Data was collected during the months of April-June 2010 using the Core Alcohol and Drug Survey. The participants included a random sample of undergraduate students from 4 public universities in the Midwest. Two of the universities had policies in place allowing the sale and use of alcohol on campus, and 2 universities had policies in place prohibiting the sale and use of alcohol. There were a total of 186 participants which included 63 males and 123 females. There was statistical significance in gender, age, and participation in sports against the odds of heavy drinking (P<.05). The type of policy in place was not significantly associated with the odds of heavy drinking. Even though there was an association between gender, age, and participation in sports with the odds of heavy drinking among college students in this sample, the type of alcohol policy (wet or dry) had no association. The results demonstrate the need for the implementation of alcohol prevention strategies, in addition to policy, to reduce the number of college students who drink heavily. It may be beneficial to target those alcohol intervention programs to the high risk groups such as males, over the age of 21, and those students who participate in sports. © Springer Science+Business Media, LLC (outside the USA) 2011.

Regulation of iron homeostasis in many pathogens is principally mediated by the ferric uptake regulator, Fur. Since acquisition of iron from the host is essential for the intracellular pathogen Listeria monocytogenes, we predicted the existence of Fur-regulated systems that support infection. We examined the contribution of nine Fur-regulated loci to the pathogenicity of L. monocytogenes in a murine model of infection. While mutating the majority of the genes failed to affect virulence, three mutants exhibited a significantly compromised virulence potential. Most striking was the role of the membrane protein we designate FrvA (Fur regulated virulence factor A; encoded by frvA [lmo0641]), which is absolutely required for the systemic phase of infection in mice and also for virulence in an alternative infection model, the Wax Moth Galleria mellonella. Further analysis of the ΔfrvA mutant revealed poor growth in iron deficient media and inhibition of growth by micromolar concentrations of haem or haemoglobin, a phenotype which may contribute to the attenuated growth of this mutant during infection. Uptake studies indicated that the ΔfrvA mutant is unaffected in the uptake of ferric citrate but demonstrates a significant increase in uptake of haem and haemin. The data suggest a potential role for FrvA as a haem exporter that functions, at least in part, to protect the cell against the potential toxicity of free haem. © 2012 McLaughlin et al. Source
