CIARD Activities in the CGIAR: Final Report on activities, outputs and lessons from the implementation of the CIARD grant to the CGIAR

CIARD activities for the CGIAR have been led by the CGIAR ICT-KM program, which has worked closely with scientists, researchers, research managers and information and communication specialists across the CGIAR: Centers, Programs and projects. This document reports on activities implemented by the CGIAR ICT-KM program through a grant (PO245548) from FAO, originally from the DFID CIARD grant, but is based on activities being undertaken by Centres, Programs and projects of the CGIAR. Special acknowledgement and appreciation is given to ILRI for hosting the CIARD CGIAR grant coordinator and its great support to learning, documentation and promotion of CIARD principles and pathways

An Investigation into Risk Perception in the ICT Industry as a Core Component of Responsible Research and Innovation

This paper makes an original contribution to the responsible research and innovation (RRI) discourse, with an inquiry into the extent to which risk, risk assessment, or risk management, including ethical and social issues, is relevant to companies. As a core component of the higher or “meta-responsibility” of RRI, an investigation of practices and attitudes towards risks can provide us with a window into companies’ attitudes towards responsible innovation that is rooted in realworld experiences. Drawing upon data from 30 in-depth interviews and a large Delphi study, we reveal different underlying attitudes towards risk governance for individuals working in the information and communication technology (ICT) industry. For some companies, there is already an obvious degree of alignment with RRI values. For others, framing of the RRI discourse in terms of ethical and societal risks may help to promote understanding and uptake. Results from the interviews suggest that lack of awareness of the full extent of ethical and societal risks associated with research and innovation in the ICT industry may act as a barrier to engagement with RRI, and educational activities may be needed to rectify this situation. Results from the Delphi survey suggest that when presented with simple information about potential ethical and societal risks, industry personnel can easily recognise the main risks and provide clear opinions about how they should be addressed. The relationship between risk governance and RRI warrants further investigation as it is an essential facet of RRI

Information and Communication Technologies— Opportunities to Mobilize Agricultural Science for Development

Knowledge, information, and data—and the social and physical infrastructures that carry them—are widely recognized as key building blocks for more sustainable agriculture, effective agricultural science, and productive partnerships among the global research community. Through investments in e-Science infrastructure and collaboration on one hand, and rapid developments in digital devices and connectivity in rural areas, the ways that scientists, academics, and development workers create, share, and apply agricultural knowledge is being transformed through the use of information and communication technologies (ICTs). This paper examines some trends and opportunities associated with the use of these ICTs in agriculturalscience for development

Ultrasound lung comets for serial assessment of pulmonary congestion in heart failure

Background: Serial chest radiographs are too insensitive and therefore NOT recommended for monitoring pulmonary congestion in heart failure patients (AHA/ACC guidelines 2006). Ultrasound lung comets (ULCs) are a simple, quantitative chest sonography sign of pulmonary congestion, originating from water-thickened interlobular septa, and might represent a convenient alternative to chest x-ray in this clinical setting. Aim: To assess whether dynamic changes in ULCs could mirror variations in clinical status and natriuretic peptides. Methods: 104 patients (28 females; age 70?11 years) admitted with dyspnoea (NYHA class &#8805;II) to a Cardiology or Emergency Department were evaluated. NT-proBNP assessment and ULC were independently performed at admission and again before discharge. A patient ULC score was obtained by summing the number of comets from each of the scanning spaces from second to fifth intercostal spaces on anterior chest. Patients were considered "responders" to therapy when NYHA class decreased &#8805;1 grade at discharge. Results: Responders (group I, n=90) and non-responders (group II, n=14) had similar NT-proBNP (I=5560?6643 vs II=5470?4047 ng/l, p=.313), and ULCs number (I=27?34 vs II=34?24, p=.133) at admission. At discharge, responders had lower NT-proBNP (I=3633?5194 vs II=4654?3366 ng/l, p<.05) and ULCs (I=11?12 vs II=28?32, p<.01, see figure) when compared to non-responders. Variation in NT-proBNP somewhat mirrored variations in ULCs (r=.322, p<0.0001). Conclusions: ULC variations mirror changes in clinical functional class and natriuretic peptides in patients hospitalized with acute dyspnoea. ULCs represent an objective parameter of clinical improvement, useful for serial assessment of extra-vascular lung water in patients admitted with acute dyspnoea

C. elegans expressing human β2-microglobulin: a novel model for studying the relationship between the molecular assembly and the toxic phenotype.

Availability of living organisms to mimic key step of amyloidogenesis of human protein has become an indispensable tool for our translation approach aiming at filling the deep gap existing between the biophysical and biochemical data obtained in vitro and the pathological features observed in patients. Human β(2)-microglobulin (β(2)-m) causes systemic amyloidosis in haemodialysed patients. The structure, misfolding propensity, kinetics of fibrillogenesis and cytotoxicity of this protein, in vitro, have been studied more extensively than for any other globular protein. However, no suitable animal model for β(2)-m amyloidosis has been so far reported. We have now established and characterized three new transgenic C. elegans strains expressing wild type human β(2)-m and two highly amyloidogenic isoforms: P32G variant and the truncated form ΔN6 lacking of the 6 N-terminal residues. The expression of human β(2)-m affects the larval growth of C. elegans and the severity of the damage correlates with the intrinsic propensity to self-aggregate that has been reported in previous in vitro studies. We have no evidence of the formation of amyloid deposits in the body-wall muscles of worms. However, we discovered a strict correlation between the pathological phenotype and the presence of oligomeric species recognized by the A11 antibody. The strains expressing human β(2)-m exhibit a locomotory defect quantified with the body bends assay. Here we show that tetracyclines can correct this abnormality confirming that these compounds are able to protect a living organism from the proteotoxicity of human β(2)-m

L-DOPA preloading increases the uptake of borophenylalanine in C6 glioma rat model: a new strategy to improve BNCT efficacy.

Purpose: Boron neutron capture therapy (BNCT) is a radiotherapeutic modality based on 10B(n,a)7Li reaction, for the treatment of malignant gliomas. One of the main limitations for BNCT effectiveness is the insufficient intake of 10B nuclei in the tumor cells. This work was aimed at investigating the use of L-DOPA as a putative enhancer for 10B-drug 4-dihydroxy-borylphenylalanine (BPA) uptake in the C6-glioma model. The investigation was first per- formed in vitro and then extended to the animal model. Methods and Materials: BPA accumulation in C6-glioma cells was assessed using radiowave dielectric spectros- copy, with and without L-DOPA preloading. Two L-DOPA incubation times (2 and 4 hours) were investigated, and the corresponding effects on BPA accumulation were quantified. C6-glioma cells were also implanted in the brain of 32 rats, and tumor growth was monitored by magnetic resonance imaging. Rats were assigned to two experimental branches: (1) BPA administration; (2) BPA administration after pretreatment with L-DOPA. All an- imals were sacrificed, and assessments of BPA concentrations in tumor tissue, normal brain, and blood samples were performed using high-performance liquid chromatography. Results: L-DOPA preloading induced a massive increase of BPA concentration in C6-glioma cells only after a 4-hour incubation. In the animal model, L-DOPA pretreatment produced a significantly higher accumulation of BPA in tumor tissue but not in normal brain and blood samples. Conclusions: This study suggests the potential use of L-DOPA as enhancer for BPA accumulation in malig- nant gliomas eligible for BNCT. L-DOPA preloading effect is discussed in terms of membrane transport mechanisms
