    Catalytic reactor, disposable cartridge enclosing iron catalyst, acts as container for solid carbon formed by decomposition of carbon monoxide. Deposition of carbon in other parts of oxygen recovery system does not occur because of lack of catalytic activity; filters trap carbon particles and prevent their being transported outside reaction zone

    Growth and Fiscal Health in Wisconsin Cities

    Get PDF
    The intent of the applied research reported in this paper is to examine the relationship between growth and the fiscal health of a subset of local governments (incorporated cities) over the last decade. While any number of researchers has raised this question, the literature has tended to focus on larger urban areas during economic downturns. Ladd's (1994) most recent research looking at the fiscal effects of growth has become perhaps the most influential in this line of work. Ladd's research, however, is limited in that she focused on per capita spending, a variable of interest in itself and because it can be conceptually linked to service quality and tax burden. While the data used in her analysis do not reflect a period of economic downturn, the data are for large counties from across the U.S. The analysis presented in this paper is intended to explore of the impact of growth on the fiscal health of smaller local governments. Annual data for Wisconsin cities from 1991 to 1998 are analyzed in this study. Six measures are used to capture different aspects of fiscal health. Changes in these measures in relation to changes in population, property values, and income are evaluated through a series of tests of subsample equivalence and regression analysis.

    Oviposition and Development of Emerald Ash Borer \u3ci\u3e(Agrilus Planipennis)\u3c/i\u3e (Coleoptera: Buprestidae) on Hosts and Potential Hosts in No-Choice Bioassays

    Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Bupres- tidae) is an invasive phloem-feeding pest native to Asia. It was first identified in North America in 2002 and has killed millions of ash (Fraxinus spp.) trees in southeast Michigan and Essex County, Ontario. Since then, additional populations have been discovered across Michigan and in areas of Ohio, Indiana, Illinois, Maryland, Pennsylvania and West Virginia. In Asia, A. planipennis reportedly colonizes other genera, including species of Juglans, Pterocarya and Ulmus. In North America, attacks on non-ash species have not been observed but there is concern about host switching as ash mortality progresses. From 2003 to 2005, we evaluated A. planipennis oviposition and larval development on 4 North American ash species: green ash (F. pennsylvanica Marshall), white ash (F. americana L.), black ash (F. nigra Marshall), blue ash (F. quadrangulata Michaux), and 6 potential alternate hosts including privet (Ligustrum and Forestiera spp.), Japanese tree lilac (Syringa reticulate (Blumb) Hara), American elm (Ulmus americana L.), black walnut (Juglans nigra L.), hickory (Carya ovata (Miller) K. Koch) and hackberry (Celtis occidentalis L.). In no- choice tests using cut branches in cages, female A. planipennis oviposited on all species tested. Larvae on green ash, white ash, black ash, blue ash and privet developed to the second instar before branches desiccated. Larvae attempted to feed on some black walnut, Japanese tree lilac, American elm and hackberry branches but died as first instars. There were no feeding attempts on hickory branches. We also conducted no-choice tests by placing adult A. planipennis in cages that encircled the lower 1 m of the trunk of live green ash, white ash, black walnut and Japanese tree lilac nursery trees. High densities of larvae developed on green ash and white ash nursery trees but there was no evidence of any larval survival, feeding, or development on the Japanese tree lilac or black walnut nursery trees

    Surgical Sterilization

    Get PDF
    Surgical sterilization as it now is practiced in Veterinary Medicine varies from careful technics carried out in an environment which would do credit to a human hospital, to the dipping of unclean instruments into a bucket of sheep dip solution of unknown strength. Even though economic considerations militate against the employment of expensive equipment and time-consuming technics, attention to a few simple details will greatly assist our approach to surgical asepsis

    Defining the content and delivery of an intervention to Change AdhereNce to treatment in BonchiEctasis (CAN-BE): a qualitative approach incorporating the Theoretical Domains Framework, behavioural change techniques and stakeholder expert panels

    Get PDF
    BACKGROUND: Low patient adherence to treatment is associated with poorer health outcomes in bronchiectasis. We sought to use the Theoretical Domains Framework (TDF) (a framework derived from 33 psychological theories) and behavioural change techniques (BCTs) to define the content of an intervention to change patients' adherence in bronchiectasis (Stage 1 and 2) and stakeholder expert panels to define its delivery (Stage 3). METHODS: We conducted semi-structured interviews with patients with bronchiectasis about barriers and motivators to adherence to treatment and focus groups or interviews with bronchiectasis healthcare professionals (HCPs) about their ability to change patients' adherence to treatment. We coded these data to the 12 domain TDF to identify relevant domains for patients and HCPs (Stage 1). Three researchers independently mapped relevant domains for patients and HCPs to a list of 35 BCTs to identify two lists (patient and HCP) of potential BCTs for inclusion (Stage 2). We presented these lists to three expert panels (two with patients and one with HCPs/academics from across the UK). We asked panels who the intervention should target, who should deliver it, at what intensity, in what format and setting, and using which outcome measures (Stage 3). RESULTS: Eight TDF domains were perceived to influence patients' and HCPs' behaviours: Knowledge, Skills, Beliefs about capability, Beliefs about consequences, Motivation, Social influences, Behavioural regulation and Nature of behaviours (Stage 1). Twelve BCTs common to patients and HCPs were included in the intervention: Monitoring, Self-monitoring, Feedback, Action planning, Problem solving, Persuasive communication, Goal/target specified:behaviour/outcome, Information regarding behaviour/outcome, Role play, Social support and Cognitive restructuring (Stage 2). Participants thought that an individualised combination of these BCTs should be delivered to all patients, by a member of staff, over several one-to-one and/or group visits in secondary care. Efficacy should be measured using pulmonary exacerbations, hospital admissions and quality of life (Stage 3). CONCLUSIONS: Twelve BCTs form the intervention content. An individualised selection from these 12 BCTs will be delivered to all patients over several face-to-face visits in secondary care. Future research should focus on developing physical materials to aid delivery of the intervention prior to feasibility and pilot testing. If effective, this intervention may improve adherence and health outcomes for those with bronchiectasis in the future

    Purified venom components inhibit EGFR phosphorylation in triple negative breast cancer

    Get PDF
    Abstract: EACR22-0963 Introduction Breast cancer remains the most commonly diagnosed type of cancer in both menopausal age women and adolescent/young adults. 10-20% of diagnosed breast cancers are deemed to be triple negative (TN), lacking expression of hormone receptors and HER2. Triple negative breast cancers (TNBC) present with poor patient prognosis, through their lack of effective treatment options. Studies report that epidermal growth factor receptor (EGFR) is expressed in 15–45% of all breast tumours and its expression is inversely related to hormone receptor expression. Expression of EGFR is indicative of poor prognosis, making it an attractive target for treatment in both TN and receptor expressing cancer subtypes. Development of resistance to current EGFR targeted therapeutics is common, leading to treatment failure and patient relapse, thus novel compound classes are needed. Venom peptides have evolved to be secreted into the lumen of the venom gland and stored ready for rapid delivery; therefore they are exceptionally stable. These proteins naturally act as ligands for a large variety of receptors and ion channels, making them a rich source of potentially novel drug like molecules. Material and Methods In this study the Venomtech Targeted-Venom Discovery ArrayEGFR (T-VDA™) containing 320 venom 2D HPLC fractions was screened using Abcam Human EGFR (pY1086) + total EGFR ELISA Kits to identify venom peptides with antagonistic activity against EGFR pY1086 phosphorylation. Optimal cell number, dosing and lysate concentrations were determined empirically. MDA-MB-468 TNBC cells were dosed at 20ug/ml for 2h with fractions, before being stimulated with 1x10-7M EGF for 5 mins. Further assay protocol was carried out as per manufacturer’s instructions. TMB Absorbance signal was measured using a CLARIOstarPLUS plate reader at 450nm (BMG LabTech). Results and Discussions Screening of the TVDAEGFR array (N=2) identified 7 hit fractions (2.2% hit rate) from the venoms of three distinct rattlesnake genera from Northern, Central and southern America, and 1 viper species from Northern Africa. These fractions were followed up with dose response, mass spec and drug like properties. Conclusion Purified protein components from the venoms of pit vipers and vipers show the capacity to antagonistically inhibit the phosphorylation of EGFR at specific tyrosine residues linked to downstream signalling pathways in TNBC cells. Thus, representing a novel chemical class for targeting EGF
