Re-imagining Your Professional Boundaries and Future Patrons: Are You Ready for Your Second Life?

Question/Purpose: To describe and demonstrate the virtual online world Second Life (SL) in the context of education, library, and health seeking behavior. Setting/Participants: An educator, a librarian, and a health seeking SL resident participate in a learner -oriented vignette on the SL Health Info Island. Brief Description: The authors will briefly describe the online virtual world SL, the relevant information seeking uses of the world, how the authors became interested in applying the online setting to health education and information dissemination, a few of the technological and social shortcomings of the site, and show a pre-recorded health education vignette in SL. Outcome: Over 7 million people worldwide have experienced SL. In many ways, the SL residents are using the virtual world in a manner similar to the geographically bounded world: meeting and communicating life experiences with new people, participating in an astonishing variety of educational sessions, and seeking informed and meaningful interaction with health professionals. Conclusion: As the world matures and SL locations become standardized with rules and interaction protocols, there will be a definite need for accurate and timely informational exchanges. There is already an information revolution occurring in SL, are you ready?https://digitalrepository.unm.edu/hslic-posters-presentations/1042/thumbnail.jp

28. Speak2Me: Using Synchronous Audio for ESL Teaching in Taiwan

The use of a synchronous audio tool is discussed for teaching English as a Second Language (ESL) in Taiwan. Over several months, a community of practice has formed among teachers and teaching assistants, transcending cultural differences. Exploring the relationship that has developed between teachers and teaching assistants forms the basis of this report. We will also consider the technology underlying Speak2Me's program and its relationship to providing students with quality pedagogy and learning flexibility

Circulating T-Cell Subsets, Monocytes, and Natural Killer Cells in Peripartum Cardiomyopathy: Results From the Multicenter IPAC Study

•Immune cell subsets were examined in healthy postpartum and peripartum cardiomyopathy (PPCM) women.•In the early postpartum, PPCM women had lower NK and higher CD3+CD4–CD8–CD38+ T cell levels.•Levels largely normalized by 6 months postpartum. The aim of this work was to evaluate the hypothesis that the distribution of circulating immune cell subsets, or their activation state, is significantly different between peripartum cardiomyopathy (PPCM) and healthy postpartum (HP) women. PPCM is a major cause of maternal morbidity and mortality, and an immune-mediated etiology has been hypothesized. Cellular immunity, altered in pregnancy and the peripartum period, has been proposed to play a role in PPCM pathogenesis. The Investigation of Pregnancy-Associated Cardiomyopathy (IPAC) study enrolled 100 women presenting with a left ventricular ejection fraction of <0.45 within 2 months of delivery. Peripheral T-cell subsets, natural killer (NK) cells, and cellular activation markers were assessed by flow cytometry in PPCM women early (<6 wk), 2 months, and 6 months postpartum and compared with those of HP women and women with non–pregnancy-associated recent-onset cardiomyopathy (ROCM). Entry NK cell levels (CD3–CD56+CD16+; reported as % of CD3– cells) were significantly (P < .0003) reduced in PPCM (6.6 ± 4.9% of CD3– cells) compared to HP (11.9 ± 5%). Of T-cell subtypes, CD3+CD4–CD8–CD38+ cells differed significantly (P < .004) between PPCM (24.5 ± 12.5% of CD3+CD4–CD8– cells) and HP (12.5 ± 6.4%). PPCM patients demonstrated a rapid recovery of NK and CD3+CD4–CD8–CD38+ cell levels. However, black women had a delayed recovery of NK cells. A similar reduction of NK cells was observed in women with ROCM. Compared with HP control women, early postpartum PPCM women show significantly reduced NK cells, and higher CD3+CD4–CD8–CD38+ cells, which both normalize over time postpartum. The mechanistic role of NK cells and “double negative” (CD4–CD8–) T regulatory cells in PPCM requires further investigation

Ocean urea fertilization for carbon credits poses high ecological risks

The proposed plan for enrichment of the Sulu Sea, Philippines, a region of rich marine biodiversity, with thousands of tonnes of urea in order to stimulate algal blooms and sequester carbon is flawed for multiple reasons. Urea is preferentially used as a nitrogen source by some cyanobacteria and dinoflagellates, many of which are neutrally or positively buoyant. Biological pumps to the deep sea are classically leaky, and the inefficient burial of new biomass makes the estimation of a net loss of carbon from the atmosphere questionable at best. The potential for growth of toxic dinoflagellates is also high, as many grow well on urea and some even increase their toxicity when grown on urea. Many toxic dinoflagellates form cysts which can settle to the sediment and germinate in subsequent years, forming new blooms even without further fertilization. If large-scale blooms do occur, it is likely that they will contribute to hypoxia in the bottom waters upon decomposition. Lastly, urea production requires fossil fuel usage, further limiting the potential for net carbon sequestration. The environmental and economic impacts are potentially great and need to be rigorously assessed
