Socio-Historical Factors Mediating Collaborative Teaching and Learning: A Design-Based Investigation and Intervention

Thesis (Ph.D.)--University of Washington, 2016-06

An MRI investigation into the function of the transversus abdominis muscle during "drawing-in" of the abdominal wall

Study Design. An operator blinded dual modality trial of measurement of the abdominal muscles during drawing-in of the abdominal wall. Objectives. 1) To investigate, using magnetic resonance imaging (MRI), the function of the transversus abdominis muscle bilaterally during a drawing-in of the abdominal wall. 2) To validate the use of real-time ultrasound imaging as a measure of the deep abdominal muscle during a drawing-in of the abdominal wall. Summary of Background Data. Previous research has implicated the deep abdominal muscle, transversus abdominis, in the support and protection of the spine and provided evidence that training this muscle is important in the rehabilitation of low back pain. One of the most important actions of the transversus abdominis is to draw-in the abdominal wall, and this action has been shown to stiffen the sacroiliac joints. It is hypothesized that in response to a draw in, the transversus abdominis muscle forms a deep musculofascial corset and that MRI could be used to view this corset and verify its mechanism of action on the lumbopelvic region. Methods. Thirteen healthy asymptomatic male elite cricket players aged 21.3 +/- 2.1 years were imaged using MRI and ultrasound imaging as they drew in their abdominal walls. Measurements of the thickness of the transversus abdominis and internal oblique muscles and the slide of the anterior abdominal fascia were measured using both MRI and ultrasound. Measurement of the whole abdominal cross-sectional area (CSA) was conducted using MRI. Results. Results of the MRI demonstrated that, as a result of draw-in, there was a significant increase in thickness of the transversus abdominis (P < 0.001) and the internal oblique muscles (P < 0.001). There was a significant decrease in the CSA of the trunk (P < 0.001). The mean slide ( +/- SD) of the anterior abdominal fascia was 1.54 +/- 0.38 cm for the left side and 1.48 +/- 0.35 cm for the right side. Ultrasound measurements of muscle thickness of both transversus abdominis and the internal oblique, as well as fascial slide, correlated with measures obtained using MRI (interclass correlations from 0.78 to 0.95). Conclusions. The MRI results demonstrated that during a drawing-in action, the transversus abdominis contracts bilaterally to form a musculofascial band that appears to tighten (like a corset) and most likely improves the stabilization of the lumbopelvic region. Real-time ultrasound imaging can also be used to measure changes in the transversus abdominis during the draw-in maneuver.

Investigation into the biochemical changes in Tourette Syndrome with a potential for pharmacological manipulation

Kynurenine (KYN) is the first stable metabolite of the kynurenine pathway, which accounts for over 95% of tryptophan metabolism. Two previous studies by this research group reported elevated plasma KYN in Tourette syndrome (TS) patients when compared with age and sex matched controls and another study showed that KYN potentiated 5-HT2A-mediated head-shakes (HS) in rodents. These movements have been suggested to model tics in TS. This raised the questions how KYN acts in eliciting this response and whether it is an action of its own or of a further metabolite along the kynurenine pathway. In the liver, where most of the kynurenine pathway metabolism takes place under physiological conditions, the first and the rate limiting enzyme is tryptophan-dioxygenase (TDO) which can be induced by cortisol. In extrahepatic tissues the same step of the pathway is catalyzed by indoleamine-dioxygenase (IDO), which is induced by cytokines, predominantly interferon-y (INF-y). Plasma neopterin, which shows parallel increase with KYN following immune stimulation, was also found elevated in one of these studies positively correlating with KYN. In the present work animal studies suggested that KYN potentiates and quinolinic acid (QUINA) dose dependently inhibits the 5-HT2A-mediated HS response in mice. The potentiating effect seen with KYN was suggested to be an effect of KYN itself. Radioligand binding and phosphoinositide (PI) hydrolysis studies were done to explore the mechanisms by which kynurenine pathway metabolites could alter a 5-HT2A-receptor mediated response. None of the kynurenine pathway metabolites tested showed direct binding to 5-HT2A-receptors. PI hydrolysis studies with KYN and QUINA showed that KYN did not have any effect while QUINA inhibited 5-HT2A-mediated PI hydrolysis. Plasma cortisol determination in TS patients with elevated plasma KYN did not show elevated plasma cortisol levels, suggesting that the increase of plasma KYN in these TS patients is unlikely to be due to an increased TDO activity induced by increased cortisol. Attention deficit hyperactivity disorder (ADHD) is commonly associated with TS. Salivary cortisol detected in a group of children primarily affected with ADHD showed significantly lower salivary cortisol levels when compared with age and sex matched controls. Plasma tryptophan, KYN, neopterin, INF-y and KYN/tryptophan ratio and night-time urinary 6-sulphatoxymelatonin (aMT6s) excretion measured in a group of TS patients did not show any difference in their levels when compared with age and sex matched controls, but TS patients failed to show the expected positive correlation seen between plasma INF-y, neopterin and KYN and the negative correlation seen between plasma KYN and night-time urinary aMT6s excretion seen in healthy controls. The relevance of the kynurenine pathway, melatonin secretion and cortisol to Tourette Syndrome and associated conditions and the mechanism by which KYN and QUINA alter the 5-HT2A-receptor mediated HS response are discussed.

Investigation of the antiproliferative properties of tumour promoting phorbol esters and related compounds

Tumour promoting phorbol esters such as 12-0-tetradecanoylphorbol-13-acetate (TPA) exert a multitude of biological effects on many cellular systems, many of which are believed to be mediated via the activation of the enzyme protein kinase C (PKC). TPA and other biologically active phorbol esters inhibited the proliferation of the A549 human lung carcinoma cell line. However, after 5-6 days culture in the continued presence of the phorbol ester cells began to proliferate at a rate similar to that of untreated cells. Resistance to TPA was lost following subculturing, although subculture in the presence of 10 nM TPA for more than 9 weeks resulted in a more resistant phenotype. The selection of a TPA-resistant subpopulation was not responsible for the observed resistance. The antiproliferative properties of other PKC activators were investigated. Mezerein induced the same antiproliferative effects as TPA but synthetic diacylglycerols (DAGs), the presumed physiological ligands of PKC, exerted only a non-specific cytotoxic influence on growth. Bryostatins 1 and 2 were able to induce transient growth arrest of A549 cells in a manner similar to phorbol esters at nanomolar concentrations, but at higher concentrations blocked both their own antiproliferative action and also that of phorbol esters and mezerein. Fourteen compounds synthesized to mimic features of the phorbol ester pharmacophore and/or DAGs did not mimic the antiproliferative properties of TPA in A549 cells and exerted only a DAG-like non-specific cytotoxicity at high concentrations. The subcellular distribution and activity of PKC was determined following partial purification by non-denaturing polyacrylamide gel electrophoresis. Treatment with TPA, mezerein or bryostatins resulted in a concentration-dependent shift of PKC activity from the cytosol to cellular membranes within 30 min. Significant translocation was not observed on treatment with DAGs. Chronic exposure of cells to TPA caused a time- and concentration dependent down-regulation of functional PKC activity. A complete loss of PKC activity was also observed on treatment with growth-inhibitory concentrations of bryostatins. No PKC activity was detected in cells resistant to the growth-inhibitory influence of TPA. Measurement of intracellular Ca2+ concentrations using A549 cells cultured on Cytodex 1 microcarrier beads revealed that TPA, mezerein and the bryostatins induced a similar rapid rise in intracellular Ca2+ levels.

An investigation of the effects of antitumour and other drugs on cell morphology and the cytoskeleton of erythrocytes

Human arythrocytes were used as a model system for an investigation of the mechanism of action of the antiproliferative drug Adriamycin. Erythrocytes were induced to undergo a change in morphology by elevation of intracellular calcium. It was revealed that the widely used media employed for the study of morphological change were unsuitable; a new incubation medium was developed so that cells were metabolically replete. In this medium echinocytosis took place both in a calcium concentration- and time-dependent manner. Pretreatment of erythrocytes with Adriamycin (10 M for 10 mins) protected the erythrocytes against calcium-induced echinocytosis at calcium concentrations < 150M. SDS-PAGE analysis of the cytoskeletal proteins prepared from erythrocytes revealed the calcium-induced proteolysis of two main cytoskeletal proteins: band 2:1 and band 4:1. Only the rate of the proteolysis of band 2.1 correlated with the onset of echinocytosis. Adriamycin inhibited the breakdown of band 2.1 even when the cells formed echinocytes; this raises doubts concerning the importance of band 2.1 in the maintenance of discocyte morphology. Adriamycin only marginally inhibited the purified calcium-activated thio protease (calpain). Calcium-loading of human erythrocytes increased the phosphorylation of several major cytoskeletal proteins including pp120, band 3, band 4.1 and band 4.9. The pattern of increase resembled that induced by 12-0-tetradecanoyl-phorbol-13-acetate. Pre-treatment with Adriamycin prior to calcium loading caused a general lowering of basal phosphorylation. Adriamycin had no effect on the activity of the calcium-activated phospholipid-dependent protein kinase (protein kinase C). A hypothesis is put forward that the morphological transition of erythrocytes might be dependent upon the activity of a contractile system.

An investigation into enterprise structure and ERP implementations:a contribution to praxis

This professional doctoral research reports on the relationship between Enterprise Systems, specifically Enterprise Resource Planning Systems, and enterprise structures. It offers insights and guidance to practitioners on factors for consideration in the implementation of ERP systems in organisations operating in modern enterprise structures. It reports on reflective ethnographic action research conducted in a number of companies from a diverse range of industries covering supply chains for both goods and services. The primary contribution is in highlighting areas in which clients, practitioners and ERP software vendors can bring a greater awareness of internet era enterprise structures and business requirements into the ERP arena. The concepts and insights have been explored in a focus group setting, comprised of practitioners from the enterprise systems implementation and consulting fraternity and revealed limitations and constraints in the implementation of enterprise systems. However, it also showed that current systems do not have the full capabilities required to support, in use, modern era enterprise structures, as required by practitioners and decision makers.

Pilot investigation of the changes in cortical activation during facial affect recognition with lamotrigine monotherapy in bipolar disorder

Background: Bipolar disorder is associated with dysfunction in prefrontal and limbic areas implicated in emotional processing. Aims: To explore whether lamotrigine monotherapy may exert its action by improving the function of the neural network involved in emotional processing. Method: We used functional magnetic resonance imaging to examine changes in brain activation during a sad facial affect recognition task in 12 stable patients with bipolar disorder when medication-free compared with healthy controls and after 12 weeks of lamotrigine monotherapy. Results: At baseline, compared with controls, patients with bipolar disorder showed overactivity in temporal regions and underactivity in the dorsal medial and right ventrolateral prefrontal cortex, and the dorsal cingulate gyrus. Following lamotrigine monotherapy, patients demonstrated reduced temporal and increased prefrontal activation. Conclusions: This preliminary evidence suggests that lamotrigine may enhance the function of the neural circuitry involved in affect recognition.

The implementation of supply chain management theory in practice:an empirical investigation

Purpose: The purpose of the research described in this paper is to disentangle the rhetoric from the reality in relation to supply chain management (SCM) adoption in practice. There is significant evidence of a divergence between theory and practice in the field of SCM. Design/methodology/approach: Based on a review of extant theory, the authors posit a new definitional construct for SCM – the Four Fundamentals – and investigated four research questions (RQs) that emerged from the theoretical review. The empirical work comprised three main phases: focussed interviews, focus groups and a questionnaire survey. Each phase used the authors’ definitional construct as its basis. While the context of the paper’s empirical work is Ireland, the insights and results are generalisable to other geographical contexts. Findings: The data collected during the various stages of the empirical research supported the essence of the definitional construct and allowed it to be further developed and refined. In addition, the findings suggest that, while levels of SCM understanding are generally quite high, there is room for improvement in relation to how this understanding is translated into practice. Research limitations/implications: Expansion of the research design to incorporate case studies, grounded theory and action research has the potential to generate new SCM theory that builds on the Four Fundamentals construct, thus facilitating a deeper and richer understanding of SCM phenomena. The use of longitudinal studies would enable a barometer of progress to be developed over time. Practical implications: The authors’ definitional construct supports improvement in the cohesion of SCM practices, thereby promoting the effective implementation of supply chain strategies. A number of critical success factors and/or barriers to implementation of SCM theory in practice are identified, as are a number of practical measures that could be implemented at policy/supply chain/firm level to improve the level of effective SCM adoption. Originality/value: The authors’ robust definitional construct supports a more cohesive approach to the development of a unified theory of SCM. In addition to a profile of SCM understanding and adoption by firms in Ireland, the related critical success factors and/or inhibitors to success, as well as possible interventions, are identified.
