Heter-LP: A Heterogeneous Label Propagation Method for Drug Repositioning.

Methods Mol Biol 2019 ;1903:291-316

Department of Systems and Computer Engineering, Carleton University, Ottawa, ON, Canada.

Using existing drugs for diseases which are not developed for their treating (drug repositioning) provides a new approach to developing drugs at a lower cost, faster, and more secured. We proposed a method for drug repositioning which can predict simple and complex relationships between drugs, drug targets, and diseases. Since biological networks typically present a suitable model for relationships between different biological concepts, our primary approach is to analyze graphs and complex networks in the study of drugs and their therapeutic effects.

Scalable Inference of Ordinary Differential Equation Models of Biochemical Processes.

Methods Mol Biol 2019 ;1883:385-422

Institute of Computational Biology, Helmholtz Zentrum München, Neuherberg, Germany.

Ordinary differential equation models have become a standard tool for the mechanistic description of biochemical processes. If parameters are inferred from experimental data, such mechanistic models can provide accurate predictions about the behavior of latent variables or the process under new experimental conditions. Complementarily, inference of model structure can be used to identify the most plausible model structure from a set of candidates, and, thus, gain novel biological insight. Read More

Department of Medicine, Division of Diabetes, Endocrinology, and Metabolism, 7465 Medical Research Bldg IV, Vanderbilt University Medical Center, 2215 Garland Avenue, Nashville, TN, 37232-0475, USA.

Over the last two decades, improved access to human islets and the development of human islet distribution networks have enabled the use of millions of human islets in hundreds of scientific research projects, leading to a dramatic increase in our understanding of human islet biology. Here we discuss recent scientific advances as well as methodological and experimental challenges that impact human islet quality, experimental outcomes and the reporting of human islets used in scientific publications. In a survey of over 200 scientific publications with human islet experimentation, we found that the reporting of critical information was quite variable, sometimes obscure, and often failed to adequately outline the experiments and results using human islets.

Neptunium(iv)-hydroxamate complexes: their speciation, and kinetics and mechanism of hydrolysis.

Dalton Trans 2018 Dec 14. Epub 2018 Dec 14.

National Nuclear Laboratory, Central Laboratory, Sellafield, Cumbria CA20 1PG, UK.

Simple hydroxamic acids such as acteohydroxamic acid (AHA) have been identified as suitable reagents for the control of Pu and Np in advanced separation processes for nuclear fuel reprocessing such as the Advanced PUREX or UREX based recycle processes, due to their ability to strip the tetravalent form of Pu and Np from tri-butyl phosphate into nitric acid. However, both free and metal bound hydroxamates are known to undergo acid catalysed hydrolysis at low pH, the kinetics of which must be characterised before implementation of PUREX/UREX based reprocessing flowsheets. In support of this implementation, a comprehensive thermodynamic and kinetic model that describes both the complex speciation and hydrolysis of AHA in the presence of Np(iv) has been developed.
