This study examines the effect of negative emotional intensity in environmental public service announcements on cognitive processing and behavioral intent. Environmental PSAs with three different levels of negative emotion were used to determine effects on secondary task reaction time (STRT), recognition, and behavioral intent. The data collected showed that recognition performance was highest at the moderate intensity level, and significantly dropped at the low intensity level. STRT results were interesting in that STRT was fastest at the moderate intensity level, and dropped significantly at the high intensity level. Behavioral intent data showed that participants were most likely to support the message sponsor when the message used moderately negative emotion. Future research will shed more light on interpreting STRT as well as the relationship between emotion and cognition

A randomized open study to assess the efficacy and tolerability of dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in Cambodia.

OBJECTIVES: To compare the efficacy and tolerability of dihydroartemisinin-piperaquine (DHA-PQP) with that of a 3-day regimen of mefloquine and artesunate (MAS3) for the treatment of uncomplicated falciparum malaria in Cambodia. METHOD: Randomized open-label non-inferiority study over 64 days. RESULTS: Four hundred and sixty-four patients were included in the study. The polymerase chain reaction genotyping-adjusted cure rates on day 63 were 97.5% (95% confidence interval, CI, 93.8-99.3) for DHA-PQP and 97.5% (95% CI, 93.8-99.3) for MAS3, P = 1. There were no serious adverse events, but significantly more episodes of vomiting (P = 0.03), dizziness (P = 0.002), palpitations (P = 0.04), and sleep disorders (P = 0.03) reported in the MAS3 treatment group, consistent with the side-effect profile of mefloquine. CONCLUSIONS: DHA-PQP was as efficacious as MAS3, but much better tolerated, making it more appropriate for use in a routine programme setting. This highly efficacious, safe and more affordable fixed-dose combination could become the treatment of choice for Plasmodium falciparum malaria in Cambodia

Three essays on food insecurity, nutritional outcomes, and supplemental nutrition assistance program participation among seniors /

As the senior population in the United States grows to be a more significant portion of the American populous, social scientists, public health advocates, policy makers, and health care professor must grapple with how to address the strain senior will place on health systems and social services. Nutrition is a critical component of maintaining good health, managing chronic diseases, and prevention, thus, we must learn more about the senior experiences with nutrition and social programs which address nutrition inadequacy. To contribute to this literature this dissertation uses nationally representative survey data and econometric analysis to understand seniors and nutrition. The first essay focuses on understanding what contributes to seniors' participation Supplemental Nutrition Assistance Program. The second essay looks at the role food security and functional limitations play in seniors' nutritional outcomes. The third chapter explores what drives the higher food insecurity rates among senior women relative to senior men. All three essays highlight potential barriers for seniors having quality nutrition.Dr. Colleen Heflin, Dissertation Supervisor.|Includes vita.Includes bibliographical references

Development of a Faculty Learning Community to support Scholarship and Feedback

In an effort to explore the ideas of Scholarship of Learning and Teaching, and to comply with Glasgow’s University’s career development programme, a small group of academics from the College of Medicine, Veterinary and Life Sciences established a Learning Community. The LC has several aims: • To create and design a Learning Community to support scholarship and progression for lecturers on learning & teaching track • To understand how a Learning Community can be used to support staff on career development pathways • To empower participants to engage in the University’s career development programme through peer support and peer mentorship within the Learning Community • provide practical support for scholarship projects (it is hoped that all members will be supported to drive their scholarship ‘from idea to manuscript’) It is hoped that through the sharing of ideas, and collaboration between schools, the LC hope to publish and disseminate scholarship, and provide a series of recommendations regarding scholarship support. Planned scholarship outputs include papers in educational journals, conference abstracts and presentations, and a significant ambition to influence policy within the university regarding scholarship and career development

The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa

Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts. It is largely unknown, however, how pseudomonads themselves respond to – and survive in the presence of – these compounds. Using Pseudomonas aeruginosa DNA microarrays and quantitative RT-PCR, we demonstrate that the phenazine pyocyanin elicits the upregulation of genes/operons that function in transport [such as the resistance-nodulation-cell division (RND) efflux pump MexGHI-OpmD] and possibly in redox control (such as PA2274, a putative flavin-dependant monooxygenase), and downregulates genes involved in ferric iron acquisition. Strikingly, mexGHI-opmD and PA2274 were previously shown to be regulated by the PA14 quorum sensing network that controls the production of virulence factors (including phenazines). Through mutational analysis, we show that pyocyanin is the physiological signal for the upregulation of these quorum sensing-controlled genes during stationary phase and that the response is mediated by the transcription factor SoxR. Our results implicate phenazines as signalling molecules in both P. aeruginosa PA14 and PAO1
