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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
