A FAIR guide for data providers to maximise sharing of human genomic data.

It is generally acknowledged that, for reproducibility and progress of human genomic research, data sharing is critical. For every sharing transaction, a successful data exchange is produced between a data consumer and a data provider. Providers of human genomic data (e.g., publicly or privately funded repositories and data archives) fulfil their social contract with data donors when their shareable data conforms to FAIR (findable, accessible, interoperable, reusable) principles. Based on our experiences vi...

Development and application of an exchange model for anisotropic water diffusion in the microporous MOF aluminum fumarate.

Diffusion of water in aluminum fumarate was studied by means of pulsed field gradient (PFG) nuclear magnetic resonance (NMR). Due to water molecules exchanging between the intracrystalline anisotropic pore space and the isotropic intercrystalline void space the model of intracrystalline anisotropic diffusion fails to describe the experimental PFG NMR data at high observation times. Therefore, the two-site exchange model developed by Kärger is extended to the case of exchange between an anisotropic and an i...

On-line Optimization of Total Acceptance in Hamiltonian Replica Exchange Simulations.

Replica exchange is a widely used sampling strategy in molecular simulation. While a variety of methods exist to optimize parameters for temperature replica exchange, less is known about how to optimize parameters for more general Hamiltonian replica exchange simulations. We present an algorithm for the on-line optimization of total acceptance for both temperature and Hamiltonian replica exchange simulations using stochastic gradient descent. We optimize the total acceptance, a heuristic objective function ...

Fast Magic-Angle-Spinning 19F Spin Exchange NMR for Determining Nanometer 19F-19F Distances in Proteins and Pharmaceutical Compounds.

Internuclear distances measured using NMR provide crucial constraints of three-dimensional structures, but are often restricted to about 5 Å due to the weakness of nuclear-spin dipolar couplings. For studying macromolecular assemblies in biology and materials science, distance constraints beyond 1 nm will be extremely valuable. Here we present an extensive and quantitative analysis of the feasibility of 19F spin exchange NMR for precise and robust measurements of inter-atomic distances to 1.6 nm at a magne...

Hospitals' adoption of intra-system information exchange is negatively associated with inter-system information exchange.

U.S. policy on interoperable HIT has focused on increasing inter-system (ie, between different organizations) health information exchange. However, interoperable HIT also supports the movement of information within the same organization (ie, intra-system exchange).

Water Exchange Produces Significantly Higher Adenoma Detection Rate Than Water Immersion: Pooled Data From 2 Multisite Randomized Controlled Trials.

To test the hypothesis that water exchange (WE) significantly increases adenoma detection rates (ADR) compared with water immersion (WI).

Probing the mechanism of thermally driven thiol-Michael dynamic covalent chemistry.

The kinetics and mechanism of the thermally activated dynamic covalent exchange of thiol-Michael adducts is investigated. A model system of thiol-Michael adducts between thiophenol and phenylvinylketone derivatives and adducts between 2-mercaptoethanol phenylvinylketone derivatives in N,N-dimethylformamide (DMF) at elevated temperatures is used to probe the underlying exchange mechanism. The kinetic data show negligible free Michael acceptor, which is consistent with the highly efficient thiol-Michael react...

Determination of Backbone Amide Hydrogen Exchange Rates of Cytochrome c Using Partially Scrambled Electron Transfer Dissociation Data.

The technological goal of hydrogen/deuterium exchange-mass spectrometry (HDX-MS) is to determine backbone amide hydrogen exchange rates. The most critical challenge to achieve this goal is obtaining the deuterium incorporation in single-amide resolution, and gas-phase fragmentation may provide a universal solution. The gas-phase fragmentation may generate the daughter ions which differ by a single amino acid and the difference in deuterium incorporations in the two analogous ions can yield the deuterium inc...

Genetic data sharing: a new type of capital.

Over the last three decades, various biotech companies, mostly in North America, have become experts in the production, processing and analysis of large volumes of genetic data. They have surpassed the performance of traditional academic platforms, by appropriating a new economic model: the two-sided market. Thus, by applying web 2.0 ideas, these biotech companies have made it possible for millions of users to produce and "share" data including genetic data, with each other and with third parties through a...

Quo Vadis Data Linkage in Germany? An Initial Inventory.

In recent years, linking different data sources, also called data linkage or record linkage, to address scientific questions, is being increasingly used in Germany. However, there are very few published reports and new projects develop the necessary tools independently of each other. Therefore, a team of researchers joined together to exchange their experiences on data linkage and to give suggestions on how linkage could be done for scientists, reviewers as well as members of data privacy boards and ethics ...

Production of dynamic lipid bilayers using the reversible thiol-thioester exchange reaction.

Thiol lysolipids undergo thiol-thioester exchange with two phenyl thioester-functionalized tails to produce phospholipid structures that assemble into liposomes with differences in exchange rates, temperature sensitivity, permeability, and continued exchange behavior. This in situ formation reaction imparts dynamic characteristics into the membrane for downstream liposome functionalization and mimics native membrane remodeling.

Research on adsorption of Cr(Ⅵ) by Poly-epichlorohydrin-dimethylamine (EPIDMA) modified weakly basic anion exchange resin D301.

A novel composite, EPIDMA/D301, with high adsorption capacity and particular affinity toward Cr(Ⅵ) was well prepared utilizing cationic polyelectrolyte poly-epichlorohydrin-dimethylamine (EPIDMA) impregnated in the networking pores of the styrene macroporous weak basic anion exchange resin D301. The physicochemical characteristics of EPIDMA/D301 were characterized by the Brunauer-Emmett-Teller (BET), zeta potential, FTIR, SEM-Mapping and XPS. The adsorption properties were researched via the influence of ...

Capturing exchange using periodic radiofrequency irradiation.

The dynamics of spin system coupled by chemical exchange between two sites with different chemical shifts during periodic radiofrequency (RF) irradiation was here investigated. When the instantaneous π-flip of effective frequency during the course of frequency sweep was applied, a significant increase of exchange-induced relaxation rate constants was observed for small tip angle of magnetization in the laboratory frame of reference. This increase of the rate constants corresponds to the side bands generate...

The Kärger vs bi-exponential model: Theoretical insights and experimental validations.

We revise three common models accounting for water exchange in pulsed-gradient spin-echo measurements: a bi-exponential model with time-dependent water fractions, the Kärger model, and a modified Kärger model designed for restricted diffusion, e.g. inside cells. The three models are compared and applied to experimental data from yeast cell suspensions. The Kärger model and the modified Kärger model yield very close results and accurately fit the data. The bi-exponential model, although less rigorous, ha...

The reHISS Three-Range Exchange Functional with an Optimal Variation of Hartree-Fock and Its Use in the reHISSB-D Density Functional Theory Method.

In the present study, we have reparametrized the HISS exchange functional. The new "reHISS" exchange provides a balance between short- and mid-range Hartree-Fock exchange (HFX) and a large total HFX coverage, with a fast convergence to zero HFX in the long range. The five parameters in this functional (according to equations 3 and 4 in the main text) are c = 0.15, c = 2.5279, c = 0, ω = 0.27, and ω = 0.2192. The combination of reHISS exchange with a reparametrized B97c-type correlation functional (Chan et...

Subunit Exchange in Protein Complexes.

Over the past 50 years, protein complexes have been studied with techniques such as X-ray crystallography and electron microscopy, generating images which although detailed are static and homogeneous. More recently, limited application of in vivo fluorescence and other techniques has revealed that many complexes previously thought stable and compositionally uniform are dynamically variable, continually exchanging components with a freely circulating pool of "spares". Here, we consider the purpose and prev...

Amber in prehistoric Iberia: New data and a review.

Provenancing exotic raw materials and reconstructing the nature and routes of exchange is a major concern of prehistoric archaeology. Amber has long been recognised as a key commodity of prehistoric exchange networks in Europe. However, most science-based studies so far have been localised and based on few samples, hence making it difficult to observe broad geographic and chronological trends. This paper concentrates on the nature, distribution and circulation of amber in prehistoric Iberia. We present new ...

Site-Specific Hydrogen Exchange in a Membrane Environment Analyzed by Infrared Spectroscopy.

Hydrogen exchange is a powerful method to examine macro-molecules. In membrane proteins, exchange can distinguish between solvent accessible and inaccessible residues due to shielding by the hydrophobic environment of the lipid bilayer. Herein, rather than examining which residues undergo hydrogen exchange, we employ a protocol that enables the full deuteration of all polar hydrogens in a membrane protein. We then measure the impact of hydrogen exchange on the shift of the amide I vibrational mode of indivi...

Exchange Coupling in Soft Magnetic Nanostructures and its Direct Effect on their Theranostic Properties.

Exchange coupling between hard and soft magnetic materials at the nanoscale exhibit novel or improved physical properties for energy and data storage applications. Recently, exchange coupling has also been explored in core/shell magnetic nanostructures (MNS) composed of hard and soft magnetic spinel ferrites but applications has been limited in biomedicine due to the presence of 'toxic' cobalt based ferrites as hard magnetic component. We report core/shell MNS where both core and shell components are soft m...

The Performance of two silica based ion exchange resins in the separation of Bi from its parent solution of Ac.

The performance of two inorganic ion exchange resins, Isolute SCX and Isolute SCX-2, were compared to the performance of the organic resin AG-50X8 in the separation of the radionuclide bismuth-213 from its parent solution of actinium-225. The breakthrough of the actinium-225 for all three columns was well below the toxicity level but the Isolute SCX and Isolute SCX-2 produced less of the bismuth-213 available on the column.

Arboreal crops on the medieval Silk Road: Archaeobotanical studies at Tashbulak.

During the first millennium A.D., Central Asia was marked by broad networks of exchange and interaction, what many historians collectively refer to as the "Silk Road". Much of this contact relied on high-elevation mountain valleys, often linking towns and caravanserais through alpine territories. This cultural exchange is thought to have reached a peak in the late first millennium A.D., and these exchange networks fostered the spread of domesticated plants and animals across Eurasia. However, few systematic...
