    Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2010.Vita. Cataloged from PDF version of thesis.Includes bibliographical references.Magic Angle Spinning (MAS) solid state nuclear magnetic resonance (SSNMR) is a developing method for determining the structures and studying the dynamics and functions of biological molecules. This method is particularly important for systems, such as amyloidogenic fibrous proteins, that do not crystallize or dissolve well and are therefore not amendable to X-ray or solution NMR techniques. However, due to inherently low sensitivity, NMR experiments may require weeks to obtain spectra with sufficient signal-to-noise ratio. This issue is further exacerbated for biological systems of interest due to their large size and limited mass availability. The sensitivity can be increased by two orders of magnitude by combining MAS NMR with dynamic nuclear polarization (DNP). The application of SSNMR-DNP to protein structure determination is explored using malonic acid and a model peptide system, WT-TTR105-115. A custom built MAS-SSNMR probe is modified for the purpose of MAS-SSNMR DNP experiments.by Rebecca Maria Mayrhofer.S.M

    Life course of retrospective harmonization initiatives:key elements to consider

    Optimizing research on the developmental origins of health and disease (DOHaD) involves implementing initiatives maximizing the use of the available cohort study data; achieving sufficient statistical power to support subgroup analysis; and using participant data presenting adequate follow-up and exposure heterogeneity. It also involves being able to undertake comparison, cross-validation, or replication across data sets. To answer these requirements, cohort study data need to be findable, accessible, interoperable, and reusable (FAIR), and more particularly, it often needs to be harmonized. Harmonization is required to achieve or improve comparability of the putatively equivalent measures collected by different studies on different individuals. Although the characteristics of the research initiatives generating and using harmonized data vary extensively, all are confronted by similar issues. Having to collate, understand, process, host, and co-analyze data from individual cohort studies is particularly challenging. The scientific success and timely management of projects can be facilitated by an ensemble of factors. The current document provides an overview of the 'life course' of research projects requiring harmonization of existing data and highlights key elements to be considered from the inception to the end of the project.</p

    EOSC-LIFE WP4 TOOLBOX: Toolbox for sharing of sensitive data - a concept description

    No full text
    The Horizon 2020 project EOSC-Life brings together the 13 Life Science ‘ESFRI’ research infrastructures to create an open, digital and collaborative space for biological and medical research. Sharing sensitive data is a specific challenge within EOSC-Life. For that reason, a toolbox is being developed, providing information to researchers who wish to share and/or use sensitive data in a cloud environment in general, and the European Open Science Cloud in particular. The sensitivity of the data may arise from its personal nature but can also be caused by intellectual property considerations, biohazard concerns, or the Nagoya protocol. The toolbox will not create new content, instead, it will allow researchers to find existing resources that are relevant for sharing sensitive data across all participating research infrastructures (F in FAIR). The toolbox will provide links to recommendations, procedures, and best practices, as well as to software (tools) to support data sharing and reuse. It will be based upon a tagging (categorisation) system, allowing consistent labelling and categorisation of resources. The current design document provides an outline for the anticipated toolbox, as well as its basic principles regarding content and sustainability
