Palladium Nanoparticles for the Deuteration and Tritiation of Benzylic Positions on Complex Molecules.

Palladium nanoparticles (PdNp) were revealed as an efficient hydrogen isotope exchange catalyst for the deuterium and tritium labeling of benzylic positions of complex molecules. A practical way to obtain small palladium nanoparticles and to apply them as a catalyst for hydrogen isotope exchange (HIE) is presented. Several model compounds and popular bioactive molecules were submitted to HIE reactions catalyzed by the PdNp.

Radiochemical Applications in Industry - A Journey through Time with RC Tritec.

Over the course of time, radioactive applications have changed from miracle cures to a material that is treated with caution in public perception. As a Swiss company, which has always been working with radioactive materials, RC Tritec is an interesting example how the applications in private industry have changed over the years: The company was originally a Ra-226 activated luminous paint manufacturer which managed to become a leader in the field of tritium labelling, the construction of manifolds for the handling of ionizing gases, source production and neutron imaging.

Unemployment and HIV mortality in the countries of the Organisation for Economic Co-operation and Development: 1981-2009.

Objectives: To determine an association between unemployment rates and human immunodeficiency virus (HIV) mortality in the Organisation for Economic Co-operation and Development (OECD).

Design: Multivariate regression analysis.

Participants: OECD member states.

Effects of economic downturns on child mortality: a global economic analysis, 1981-2010.

Objectives: To analyse how economic downturns affect child mortality both globally and among subgroups of countries of variable income levels.

Design: Retrospective observational study using economic data from the World Bank's Development Indicators and Global Development Finance (2013 edition). Child mortality data were sourced from the Institute for Health Metrics and Evaluation.
