Metabolomic Profiling to Identify Predictors of Response to Vitamin E for Non-Alcoholic Steatohepatitis (NASH)

Vitamin E was recently shown to improve hepatic histology in a randomized controlled trial of pioglitazone or vitamin E for nonalcoholic steatohepatitis (PIVENS). The current study utilized samples collected in the PIVENS trial to identify: (1) baseline metabolomic profiles that could identify who would respond to vitamin E treatment and (2) end of treatment metabolomic profiles reflective of histologic improvement. A comprehensive analysis of metabolomics profiles (n = 547) quantified by mass spectrometry was performed in vitamin E responders (n = 16), vitamin E non-responders (n = 15), and placebo responders (n = 15). At baseline, phenyl-propionic acid (Odds ratio: 29.4, p\u3c0.01), indole-propionic acid levels (Odds ratio: 16.2, p\u3c0.01) were directly associated with a subsequent histologic response to vitamin E treatment whereas γ-carboxyethylhydroxychroman (CEHC) levels were inversely related to histologic response. Adjusting for baseline values by analysis of covariance, the end of treatment levels of gamma-glutamyl leucine (Fold change: 0.82, p\u3c0.02) and gamma-glutamyl valine (Fold change: 0.8, p\u3c0.03) were significantly lower in vitamin E responders compared to non-responders. The levels of gamma-glutamyl transpeptidase were not significantly different across the two groups. Subjects receiving placebo who demonstrated a histologic improvement also demonstrated lower levels of gamma-glutamylated amino acids (leucine, valine and isoleucine) compared to vitamin E non-responders. These data provide exploratory proof that there are measurable differences in the metabolic profile of subjects who are likely (vs unlikely) to respond to vitamin E treatment for NASH and in those experiencing histologic improvement (vs no improvement) on treatment and support further studies to validate these biomarkers

Marine social sciences: Looking towards a sustainable future

Marine and coastal environments provide extensive and essential ecosystem services upon which much of humanity relies, yet the incorporation of human dimensions into marine and coastal policy and management has historically been lacking. As efforts to address the substantial and diverse challenges facing marine and coastal environments continue, recent years have seen a growing call for greater consideration of people, how they interact with the marine environment, and the resultant implications for developing effective policy and man- agement. Indeed, in recent times recognition of the importance of marine social science research, data, evidence and expertise has undergone an upward trajectory. Despite this growing level of awareness of the value of social science to the wider marine and coastal management agenda, effective and meaningful inclusion of marine social science into research and practice has remained a challenge. Here we approach this global challenge as an opportunity to bring the community together to set a forward-looking international research agenda, recognising the role of multiple approaches and diverse methods understanding the relationship between society and the sea, galvanising the research and practice community across marine social sciences and beyond. Furthermore, by bringing together this increasingly active community, we can identify mechanisms of change and pathways to enable inclusion of marine social sciences within global ocean policy. This paper draws on the views of re- searchers and practitioners from across the marine social science disciplines, brought together through an expert workshop held at the MARE 2019 conference (June 2019) and representing a range of geographical regions and perspectives. Through the workshop, delegates identified a number of priorities for the ongoing development of the marine social science community, including the need to improve capacity for marine social science research globally, the importance of nurturing an inclusive and equitable marine social science research community and the role of networks to continue to raise the profile of marine social science data and evidence for global ocean policy and management. Additionally, the discussions provided valuable insight into existing knowledge gaps and potential research priorities for the future. Finally, the paper presents a future vision and recommendations for an international and interdisciplinary marine social science agenda, calling for collaborative and strategic thinking on marine social sciences from across the marine science and policy interface. Critically, we show how social science needs to be embedded in all aspects of marine and coastal management in order to create truly sustainable solutions to the pervasive environmental challenges we face

Kelvin Probe Studies of Cesium Telluride Photocathode for AWA Photoinjector

Cesium telluride is an important photocathode as an electron source for particle accelerators. It has a relatively high quantum efficiency (>1%), is sufficiently robust in a photoinjector, and has a long lifetime. This photocathode is grown in-house for a new Argonne Wakefield Accelerator (AWA) beamline to produce high charge per bunch (~50 nC) in a long bunch train. Here, we present a study of the work function of cesium telluride photocathode using the Kelvin Probe technique. The study includes an investigation of the correlation between the quantum efficiency and the work function, the effect of photocathode aging, the effect of UV exposure on the work function, and the evolution of the work function during and after photocathode rejuvenation via heating.Comment: 5 pages, 6 figure

Association Between Cytokines and Liver Histology in Children with Nonalcoholic Fatty Liver Disease.

BackgroundReliable non-invasive markers to characterize inflammation, hepatocellular ballooning, and fibrosis in nonalcoholic fatty liver disease (NAFLD) are lacking. We investigated the relationship between plasma cytokine levels and features of NAFLD histology to gain insight into cellular pathways driving NASH and to identify potential non-invasive discriminators of NAFLD severity and pattern.MethodsCytokines were measured from plasma obtained at enrollment in pediatric participants in NASH Clinical Research Network studies with liver biopsy-proven NAFLD. Cytokines were chosen a priori as possible discriminators of NASH and its components. Minimization of Akaike Information Criterion (AIC) was used to determine cytokines retained in multivariable models.ResultsOf 235 subjects, 31% had "Definite NASH" on liver histology, 43% had "Borderline NASH", and 25% had NAFLD but not NASH. Total plasminogen activator inhibitor 1 (PAI1) and activated PAI1 levels were higher in pediatric participants with Definite NASH and with lobular inflammation. Interleukin-8 (IL-8) was higher in those with stage 3-4 fibrosis and lobular inflammation. sIL-2rα was higher in children with stage 3-4 fibrosis and portal inflammation. In multivariable analysis, PAI1 variables were discriminators of Borderline/Definite NASH, definite NASH, lobular inflammation and ballooning. IL-8 increased with steatosis and fibrosis severity; sIL-2rα increased with fibrosis severity and portal inflammation. IL-7 decreased with portal inflammation and fibrosis severity.ConclusionsPlasma cytokines associated with histology varied considerably among NASH features, suggesting promising avenues for investigation. Future, more targeted analysis is needed to identify the role of these markers in NAFLD and to evaluate their potential as non-invasive discriminators of disease severity

Extent, accuracy and repeatability of bare sand and vegetation cover in dunes mapped from aerial imagery is highly variable

Vegetation cover on coastal sand dunes has been increasing worldwide since at least the 1940s. Analysis of aerial and satellite imagery has been the principal source used to measure this change, however no studies have systematically evaluated the accuracy of remotely sensed estimates. Using established land cover classification methods and in-situ field measurements, we show that both the extent and accuracy of remotely sensed areas of bare sand and vegetation in dunes varies with image resolution and classification method. We found that supervised methods of classification (semi-automatic), whilst mapping a greater extent of bare sand and being more accurate than manual digitisation, had poor repeatability, exhibiting a relatively large range of bare sand and vegetation extent between classifications replicated under the same conditions. In contrast, areas of bare sand and vegetation classified by manual digitisation had high repeatability but a relatively low percentage of observed agreement with data collected in the field. For all classification methods, observed agreement with field data generally increased with image resolution. Our results demonstrate that users of land classification data in dunes should be cautious when interpreting trends of bare sand and vegetation cover due to substantial repeatability error in supervised classification methods, and relatively poor observed agreement with field data of manual classification. We recommend that analysis of bare sand and vegetation cover in dunes should be based on multiple replicates using supervised classification, employing the highest resolution imagery available and that all results presented should also include the range measured by multiple replicates

Purpose vs performance : what does marine protected area success look like?

Marine protected areas (MPAs) are an increasingly deployed spatial management tool. MPAs are primarily designed for biodiversity conservation, with their success commonly measured using a narrow suite of ecological indicators. However, for MPAs to achieve their biodiversity conservation goals they require community support, which is dependent on wider social, economic and political factors. Despite this, research into the human dimensions of MPAs continues to lag behind our understanding of ecological responses to MPA protection. Here, we explore stakeholders’ perceptions of what MPA success is. We conducted a series of semi-structured interviews and focus groups with a diverse group of stakeholders local to a South Australian MPA. What constitutes success varied by stakeholder group, and stakeholders’ stated understanding of the purpose of the MPA differed from how they would choose to measure the MPA’s success. Indeed, all interviewees stated that the primary purpose of the MPA was ecological, yet almost all (>90%) would measure the success of the MPA using social and economic measures, either exclusively or in conjunction with ecological ones. Many respondents also stated that social and economic factors were key to the MPA achieving ongoing/future success. Respondents generated a large range of novel socio-economic measures of MPA success, many of which could be incorporated into monitoring programs for relatively little additional cost. These findings also show that success is not straightforward and what constitutes success depends on who you ask. Even where an MPA’s primary ecological purpose is acknowledged by stakeholders, stakeholders are likely to only consider the MPA a success if its designation also demonstrates social and economic benefits to their communities. To achieve local stakeholder support MPAs and associated monitoring programs need to be designed for a variety of success criteria in mind, criteria which reflect the priorities and needs of the adjacent communities as well as national and international conservation objectives
