Fungal infections can kill people with weakened immune systems, which can be caused by AIDS, cancer treatment or organ replacement, and the research reinforces earlier findings that this drug is a potent treatment for a wide range of these infections.
Voriconazole is an antifungal agent which has been approved for treatment of a broad range of fungal infections, including those caused by Candida species. The authors, from the United Kingdom, the United States of America and New Zealand, analyzed susceptibility data for the yeasts isolated from patients taking part in the voriconazole phase III clinical trials. The aim was to compare the effectiveness of voriconazole with other agents, by studying the yeasts’ response to these antifungal agents in vitro, and also to check for resistance to voriconazole.
The researchers analyzed the effect of itraconazole, fluconazole, amphotericin B and voriconazole versus 1763 yeasts isolated from samples obtained from 472 patients. The yeast cultures obtained were predominantly Candida spp. (97.1%), although there were seven genera and 22 species of yeasts in all. The infections the patients were suffering from arose most commonly from surgery/trauma/burns (37% of patients), haematological malignancy (13%) or bacteria (11%).
The authors conclude that “Voriconazole exhibits high potency in vitro against a wide range of yeast species. It is notably more active than fluconazole in terms of both potency and spectrum, but shows similar activity to itraconazole against most yeasts.” They also note that the activity of the agent in vitro may help predict the response of patients to treatment.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
