    Best Estimated Aroma and Taste Detection Threshold for Guaiacol in Water and Apple Juice (2005)

    Notes: : Alicyclobacillus acidoterrestris can produce sufficient guaiacol (methoxyphenol), a metabolic by-product of the bacterium, in apple juice to cause a detectable taint characterized by an antiseptic off-odor or distinct medicinal flavor and lingering aftertaste. Bacterial spoilage may not be visibly detectable. The objective of this study was to determine the best estimate threshold (BET) for detection of guaiacol in water and commercial pasteurized apple juice from concentrate using the forced-choice ascending concentration method of limits with an experienced 17-member sensory panel. The mean BET for aroma detection of guaiacol in water and apple juice was 0.48 ppb and 0.91 ppb, respectively. The mean BET for taste detection of guaiacol in water and apple juice was 0.17 ppb and 0.24 ppb, respectively. Individual aroma BET values ranged from 0.06 ppb to 4.71 ppb guaiacol in water and 0.17 ppb to 4.71 ppb for guaiacol in apple juice. Individual taste BET values ranged from 0.01 ppb to 4.71 ppb for guaiacol in water and apple juice. The taste BET was equal to or lower than the aroma BET for guaiacol in both water and apple juice for all panelists. There was about a 500-fold range in guaiacol taste detection between panelists, with some individuals exhibiting a BET value as low as 10 ppt (trillion). The information should be useful for developing quality assurance sensory methodology to evaluate potential apple juice flavor spoilage by Alicyclobacillus spp.

    Performance Information Systems for Emergency Response: Field Examination and Simulation of End-To-End Rural Response Systems (2005)

    Notes: This research study investigates the role of information systems in enhancing end-to-end performance of rural Emergency Medical Services (EMS) systems. This study uses an embedded case study approach with multiple methods and within the context of rural Minnesota. Interviews and data analysis of the EMS process identified four elements: mayday call, routing and dispatch, response, and treatment. These data were then used to perform a preliminary simulation of rural EMS systems performance under normal and crisis conditions as a proof of concept for analyzing end-to-end performance. This process allowed for further contextual analysis of the interviews, which revealed the need for a more dynamic and comprehensive management information system as well as a forum for sharing EMS performance information across the full range of organizations involved in EMS. Constraints to enhancing EMS systems were also identified, such as a lack of funding for new technologies and an apparent disconnect between information systems coordination and service coordination. The case study reveals that while local EMS providers may have an intuitive understanding of how the entire system performs, there is a lack of systematic data to support, confirm or refute perceptions about overall performance. The paper concludes with recommendations for future related research activities.

    Exporting Western Law to the Developing World: The Troubling Case of Niger (2008)

    Notes: In recent years the West has dispatched ``rule doctors" across the developing world to guide poor countries through the process of legal modernization and westernization. Their goal, laid out by the so-called Washington Consensus, has been to reform those countries' legal systems so that they might share in the economic bounty of globalization. But things have not always gone well, particularly - this paper argues - where those rule doctors have ignored existing legal traditions.The paper focuses on the particular case of Niger, one of the poorest countries in the world. At present, most of Niger's citizens rely on magio-religious traditions to accomplish what we in the West would consider law. One important, and from a Western perspective colorful, Nigerien legal tradition is its citizens' reliance on an oracle called the gon to identify wrongdoers and restore harmony to their communities. The paper will describe the gon, and will point out some of the ways that it differs fundamentally from Western conceptions of law. It then will conclude that Washington Consensus law reform in Niger will fail, and will very likely cause social unrest, unless it takes a different tack and finds a way to accommodate existing legal traditions.

    A 250 year comparison of historical, macrofossil and pollen records of aquatic plants in a shallow lake (2005)

    Notes: 1. Sedimentary remains of aquatic plants, both vegetative (turions, leaves, spines) and reproductive (fruits, seeds, pollen), may provide a record of temporal changes in the submerged vegetation of lakes. An independent assessment of the degree to which these remains reflect past floristic change is, however, rarely possible.2. By exploiting an extensive series of historical plant records for a small shallow lake we compare plant macrofossil (three cores) and pollen (one core) profiles with the documented sequence of submerged vegetation change since c. 1750 AD. The data set is based on 146 site visits with 658 observations including 42 taxa classified as aquatic, spanning 250 years.3. Approximately 40% of the historically recorded aquatic taxa were represented by macro-remains. In general macrofossils underestimated past species diversity, with pondweeds (three of eight historically recorded Potamogeton species were found) particularly poorly represented. Nonetheless, several taxa not reported from historical surveys (e.g. Myriophyllum alterniflorum and Characeae) were present in the sediment record.4. The pollen record revealed taxa which left no macro-remains (e.g. Littorella uniflora), and the macrofossil record provided improved taxonomic resolution for some taxa (e.g. Potamogeton) and a more reliable record of persistence, appearance and loss of others (e.g. Myriophyllum spp. and Nymphaeaceae).5. Detrended correspondence analysis indicated that changes in the community composition evidenced by the palaeolimnological and historical records were synchronous and of a similar magnitude. Both records pointed to a major change at around 1800, with the historical record suggesting a more abrupt change than the sedimentary data. There was good agreement on a subsequent change c. 1930.6. The palaeolimnological data did not provide a complete inventory of historically recorded species. Nevertheless, these results suggest that combined macrofossil and pollen records provide a reliable indication of temporal change in the dominant components of the submerged and floating-leaved aquatic vegetation of shallow lakes. As such palaeolimnology may provide a useful tool for establishing community dynamics and successions of plants over decadal to centennial timescales.

    Notes: DNA mismatch repair (MMR) is an evolutionarily conserved process that corrects mismatches generated during DNA replication and escape proofreading. MMR proteins also participate in many other DNA transactions, such that inactivation of MMR can have wide-ranging biological consequences, which can be either beneficial or detrimental. We begin this review by briefly considering the multiple functions of MMR proteins and the consequences of impaired function. We then focus on the biochemical mechanism of MMR replication errors. Emphasis is on structure-function studies of MMR proteins, on how mismatches are recognized, on the process by which the newly replicated strand is identified, and on excision of the replication error.

    Notes: MAbs directed toward tumor cells, tumor neovasculature, and host negative immunoregulatory elements (checkpoints) have emerged as useful immunotherapeutic agents against cancer. However, effective active modulation of the immune response with anticancer vaccines will require identifying appropriate tumor-rejection antigens; optimizing the interactions of peptides, antigen-presenting cells, and T cells; and blockading negative immunological checkpoints that impede an effective immune response. Checkpoints being targeted include CTLA-4 and PD1 that are negative signaling receptors expressed on activated T cells, CD4+CD25+ Foxp3-expressing Tregs (suppressor T cells), IL-2-mediated activation-induced cell death (AICD), and the cytokine TGF?‚.
