    Clinical and economic burden of invasive fungal diseases in Europe: focus on pre-emptive and empirical treatment of Aspergillus and Candida species

    Invasive fungal diseases (IFDs) have been widely studied in recent years, largely because of the increasing population at risk. Aspergillus and Candida species remain the most common causes of IFDs, but other fun...

    Effects of Isosorbide-5-Mononitrate on Haemodynamics and Exercise Tolerance in Patients with Heart Failure: Comparisons with Digoxin and Placebo

    The pre-eminence of diuretics as first-line treatment in heart failure remains virtually unchallenged but there is less certainty concerning the drugs available for second-line treatment. The longest establish...

    Report of the Working Group on Silicates

    There are at least two ways to understand the nature of grains in the universe. In one approach, one can try to understand the life history of typical particles. The fate of a grainmay e.g. be as follows: vapours...
