    Scaling sustainable nutrition for all (SN4A) in Zambia : Report community mapping
    Hove, Hermine ten; Bakker, Sanne - \ 2020
    Wageningen : Wageningen Centre for Development Innovation (Report / Wageningen Centre for Development Innovation WCDI-20-110) - 59
    This report present the finding of community mapping exercise conducted in February 2020 in Zambia. The community mapping was done in six communities in the three new Scaling Sustainable Nutrition for All (SSN4A) districts: Lunte (rural), Mporokoso (rural, peri-urban) and Mungwi (rural, peri-urban, urban), with the goal to get familiar with the context and day-to-day realities of the targeted communities, find out about the resources in place (e.g. access to water, markets, agricultural plots), their condition and use by the community; find out which social structures and differences exist in the community, and to develop a common understanding about main issues opportunities, and challenges the community faces.
    Congener patterns of polychlorinated dibenzo-p-dioxins, dibenzofurans and biphenyls as a useful aid to source identification during a contamination incident in the food chain
    Hoogenboom, Ron L.A.P. ; Malisch, Rainer ; Leeuwen, Stefan P.J. van; Vanderperren, Huig ; Hove, Helge ; Fernandes, Alwyn ; Schächtele, Alexander ; Rose, Martin - \ 2020

    Chlorophenols - Congener patterns - Dioxins - Drying - Incidents - PCBs

    Polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs) are still considered among the most important groups of contaminants in the food chain. Self-control by food producers and official control by authorities are important activities that allow contaminant sources to be traced and promote further reduction in food and feed levels. Strict but feasible maximum levels were set by the EU Commission for food and feed to support this strategy, as well as action levels and thresholds. When products exceed these levels, it is important to trace the source of contamination and take measures to remove it. Congener patterns of PCDD/Fs and PCBs differ between sources and are important tools for source identification. Therefore, patterns associated with different sources and incidents relating to various feed matrices and certain agricultural chemicals were collated from published scientific papers, with additional ones available from some laboratories. The collection was evaluated for completeness by presentations at workshops and conferences. Primary sources appear to derive from 5 categories, i) by-products from production of organochlorine chemicals (e.g. PCBs, chlorophenols, chlorinated pesticides, polyvinyl chloride (PVC)), ii) the result of combustion of certain materials and accidental fires, iii) the use of inorganic chlorine, iv) recycling/production of certain minerals, and v) certain naturally occurring clays (ball clay, kaolinite). A decision tree was developed to assist in the identification of the source.

    Disparities in cancer-related healthcare among people with intellectual disabilities:A population-based cohort study with health insurance claims data
    Cuypers, Maarten ; Tobi, Hilde ; Huijsmans, Cornelis A.A. ; Gerwen, Lieke van; Hove, Michiel ten; Weel, Chris van; Kiemeney, Lambertus A.L.M. ; Naaldenberg, Jenneken ; Leusink, Geraline L. - \ 2020

    early detection of cancer - healthcare disparities - hospital - intellectual disability - neoplasms - oncology service

    Background: Concerns have been raised about the accessibility and quality of cancer-related care for people with intellectual disabilities (ID). However, there is limited insight into cancer incidence and the utilization of cancer care at the ID population level to inform targeted cancer control strategies. Therefore, we aimed to examine differences in the utilization of cancer-related care between people with and without ID, identified through diagnostic codes on health insurance claims. Methods: In a population-based cohort study, Dutch individuals of all ages who received residential care through the Chronic Care Act due to an ID (n = 65 183) and an age and sex-matched sample of persons without ID (1:2 ratio), who were cancer-free at enrollment in 2013 were followed through 2015. Incidence rates (IRs) of newly started cancer care and IR ratios (IRRs) with 95% CIs were used to compare groups. Separate analyses were performed per cancer type. Results: Individuals with ID received less cancer-related care than individuals without (IRR = 0.64, 95% CI 0.62-0.66). Differences increased with age and were larger for females than for males. Utilization of care for cancers within the national screening program (female breast, cervical, and colon cancer) was lower for people with ID compared to people without ID. Conclusion: Cancer may be underdiagnosed and/or undertreated in people with ID, or cancer is truly less prevalent in this population. In particular, the differences detected between males and females with ID, and the potential underutilization of national screening programs, require urgent follow-up investigations.

    Evidence on effects of plant pests on IPPC strategic objectives and monitoring and evaluation mechanisms by the SPS community : Report based on literature review and interviews with SPS organisations
    Kusters, Cecile ; Hove, Hermine ten - \ 2020
    Wageningen : Wageningen Centre for Development Innovation (Report WCDI 20-108) - ISBN 9789463954051 - 44
    This report is commissioned by the International Plant Protection Commission (IPPC) and is the result of a literature review on the effects of plant pests on the IP strategic objectives, as well as interviews and document review on the monitoring and evaluation (M&E) mechanisms of the SPS community. The review shows that there is evidence that the prevention of pests contributes to IPPC’s strategic objectives: enhancing global food security and sustainable agriculture productivity; protecting the environment; and facilitating safe trade, development, and economic growth. However, the context is very important and requires context specific interventions. In particular low-income countries struggle to reduce plant pests and need support in this to help them to also contribute to these overarching objectives. The review also shows that the different SPS organisations have different mechanisms in place for monitoring and evaluation, and these are generally not embedded in a formal monitoring and evaluation system. There is need for more attention to monitoring and evaluation in support of adaptive management of the SPS organisations, that work in often complex environments.

    A SOSEKI-based coordinate system interprets global polarity cues in Arabidopsis

    Multicellular development requires coordinated cell polarization relative to body axes, and translation to oriented cell division 1–3 . In plants, it is unknown how cell polarities are connected to organismal axes and translated to division. Here, we identify Arabidopsis SOSEKI proteins that integrate apical–basal and radial organismal axes to localize to polar cell edges. Localization does not depend on tissue context, requires cell wall integrity and is defined by a transferrable, protein-specific motif. A Domain of Unknown Function in SOSEKI proteins resembles the DIX oligomerization domain in the animal Dishevelled polarity regulator. The DIX-like domain self-interacts and is required for edge localization and for influencing division orientation, together with a second domain that defines the polar membrane domain. Our work shows that SOSEKI proteins locally interpret global polarity cues and can influence cell division orientation. Furthermore, this work reveals that, despite fundamental differences, cell polarity mechanisms in plants and animals converge on a similar protein domain.

    Understanding the dynamics of discrete self-assembled structures under influence of external triggers is of interest to harvest the potential of nano- and mesoscale materials. In particular, controlling the hierarchical organization of (macro)molecular and nanoparticle building blocks in monolayer superstructures is of paramount importance for tuning properties and characteristics. Here we show how the electron beam in cryo-transmission electron microscopy can be exploited to induce and follow local migration of building blocks and global migration of micellar aggregates inside micrometer-sized superstructures. We employ stroboscopic exposure to heat up and convert the vitrified superstructure into a liquid-like thin film under cryogenic conditions, resulting in controlled evaporation of water that finally leads to rupture of the micelle-containing superstructure. Micelle-embedded nanoparticles prove a powerful tool to study the complex hierarchically built-up superstructures, and to visualize both global movement of individual dendrimicelles and local migration of nanoparticles inside the micellar core during the exposure series.

    Size-controlled and water-soluble gold nanoparticles using UV-induced ligand exchange and phase transfer
    Hove, Jan Bart ten; Schijven, Laura M.I. ; Wang, Junyou ; Velders, Aldrik H. - \ 2018
    Chemical Communications 54 (2018)95. - ISSN 1359-7345 - p. 13355 - 13358.

    Oleylamine-capped gold nanoparticles (AuNPs) with sizes ranging from 5 to 13 nm and narrow size distributions (<10%) are synthesized by using a seeded growth approach. Water-solubility is achieved by using a UV-induced ligand exchange approach, resulting in transfer from the organic to an aqueous phase.

    Cyclodextrin-based complex coacervate core micelles with tuneable supramolecular host–guest, metal-to-ligand and charge interactions

    Micelles have been recognized as versatile platforms for different biomedical applications, from bioimaging to drug delivery. Complex coacervate core micelles present great advantages compared to traditional micelles, however controlling the number of charges per core-unit and the stability is still a challenge. We here present cyclodextrin-based complex coacervate core micelles where the charge per core-unit can be straightforwardly tuned by cyclodextrin host–guest interactions. By varying the ratio between two adamantane guest molecules, 1-adamantanecarboxylic acid and 1,3-adamantanediacetic acid, the charge of the monomeric core-units can be finely tuned from 6− to 9−. By adding an adamantane bislinker, monomeric core-units can be combined together in dimeric and polymeric structures, increasing the micelles’ stability. The orthogonal supramolecular host–guest and coordination-chemistry allows for well-controlled cyclodextrin-based complex coacervate core micelles that offer a versatile platform for designing future, e.g., responsive systems.
    Clever and cool : generating design guidelines for climate-responsive urban green infrastructure
    Klemm, Wiebke - \ 2018
    Wageningen University. Promotor(en): A. van den Brink, co-promotor(en): S. Lenzholzer; L.W.A. van Hove. - Wageningen : Wageningen University - ISBN 9789463433051 - 289

    Urban heat problems due to global climate change and urbanization may pose a serious risk to thermal comfort related public health in cities. Urban green infrastructure (UGI), such as parks, gardens and street trees, has the ability to alleviate urban heat and improve residents’ thermal comfort during warm summer days. Research in the field of urban micrometeorology delivers insights into the impacts of UGI on objective thermal conditions. Yet, this knowledge lacks insights into impacts of UGI on people’s subjective thermo-spatial perception and does not match the demand of spatially explicit information by urban designers. Consequently, urban designers lack guidance in the design of climate-responsive UGI in outdoor urban spaces.

    The development of a spatially explicit evidence of subjective and objective impacts of UGI on thermal comfort, and based on that evidence the subsequent development of useful design guidelines for climate-responsive UGI, were the objectives of this thesis. The research approach consisted of two phases: The ‘Research for Design’ approach, a combination of qualitative (surveys, observations) and quantitative (micrometeorological measurements) research methods, delivered scientific evidence needed to inform climate-responsive urban design. A set of multiscale case studies was conducted during warm summer periods in the moderate climate of the Netherlands. In a subsequent participatory ‘Research through Designing’ approach the novel scientific evidence was translated into preliminary design guidelines, and applied in practical design settings with landscape architects. Observations, plan analysis and questionnaires provided insights into the usefulness of the guidelines for end-users and directed the refinement into revised design guidelines for climate-responsive UGI.

    ‘Clever and cool’ urban green can be achieved by implementing the design guidelines for climate-responsive UGI. Findings of the first phase demonstrate that UGI enhances residents’ subjective thermal perception and improves thermal conditions in urban environments. This phase provides spatially-explicit evidence of UGI relevant for design. It furthermore shows the importance of residents’ physical adaptation in the context of thermal perception. The second phase delivered evidence-based, generally applicable design guidelines for climate-responsive UGI that are accompanied by visual representations. Additionally operational principles to support site-specific implementation of the guidelines at the respective scales. The practical design settings furthermore showed that urban designers need a basic understanding of microclimate processes and skills to conduct microclimate analysis to appropriately implement the guidelines. Concluding, this thesis argues for climate-responsive UGI that is ‘clever and cool’: UGI that is designed resource efficiently, is based on site-specific microclimate analysis, and considers spatial conditions as well as the behavioural demands of urban dwellers. Through combining perspectives and knowledge of microclimate science and design practice this thesis provides evidence-based solutions that are considered useful by end-users. As such the design guidelines for climate-responsive UGI, as presented in this thesis, can enhance urban design practice for more thermally comfortable and liveable cities now and in the future.

    Income intervention quick scan: agro-corridors : Farmer Income Lab Intervention Quick Scan
    Hove, Hermine ten - \ 2018
    Wageningen : Wageningen Centre for Development Innovation (Report / WCDI 18-024) - 18
    This quick scan, commissioned by the Farmer Income Lab, is part of a wider research effort looking at, “What are the most effective actions that lead buyers can take to enable smallholder farmers in global supply chains to meaningfully increase their incomes?”. The quick scan provides an overview of the publicly available evidence on the impact of agro-corridors have had on raising farmer income. Such subsidies have had little positive effect on farmer income, are not notably beneficial for women nor is this effect long-term. They have been applied at large scale. This quick scan is part of a series of 16, contributing to a synthesis report “What Works to Raise Farmer’s Income: a Landscape Review"

    Nanoparticles reveal Extreme Size-Sorting and Morphologies in Complex Coacervate Superstructures
    Hove, Jan Bart ten; Oosterom, Matthias N. van; Leeuwen, Fijs W.B. van; Velders, Aldrik H. - \ 2018
    Scientific Reports 8 (2018)1. - ISSN 2045-2322

    We here provide detailed insight in self-assembled complex coacervate systems exploiting gold nanoparticles for cryoTEM contrast. Nanoparticle-containing dendrimicelles are formed from fifth-generation dendrimer-encapsulated nanoparticles (DENs) and dendrimer-stabilized nanoparticles (DSNs). The complex coacervate structures self-organize in biconcave thin water layers into size-sorted monolayer superstructures. The embedded nanoparticles are a straightforward tool to visualize dendrimicelles and determine the aggregation number and polydispersity. The superstructure shows extreme size-sorting patterns which, contrary to related systems with higher generation dendrimers, consists not only of dendrimicelles but also much bigger complex coacervate nanoassemblies, such as vesicles.

    Mesoscale organization of nanoparticle assemblies: looking into superstructures and aggregates
    Hove, Jan Bart ten - \ 2018
    Wageningen University. Promotor(en): A.H. Velders, co-promotor(en): F.W.B. van Leeuwen. - Wageningen : Wageningen University - ISBN 9789463438391 - 181

    For this thesis, the goal was to investigate:

    1) the self-assembly of amine-terminated dendrimers into well-defined dendrimicelles

    2) the use of the micelle embedded nanoparticles as ‘spy’ particles

    3) the effect of a templating matrix on the self-organization of these dendrimicelles into mesoscale superstructures.

    Throughout the thesis, it is shown that well-defined, 50 nm-sized dendrimicelles can be obtained from PAMAM dendrimer generations five through nine. By combining cryoTEM and light scattering experiments, the self-assembly behavior of the dendrimicelles is studied in unique detail. The dendrimicelle-embedded nanoparticles serve a dualistic purpose; not only do they provide additional contrast in the cryoTEM micrographs, they also allow for the direct determination of the micelle aggregation numbers by simply counting the number of nanoparticles.
