The study is being published as a “sneak preview” research article ahead of the official launch of PLoS Neglected Tropical Diseases later this year.
Recent reports of patients failing to respond to ivermectin treatment have suggested the emergence of drug-resistant Onchocerca volvulus (the parasite that causes river blindness), and recent studies have associated ivermectin resistance with certain genetic markers, particularly the ß-tubulin gene. In Prichard and colleagues’ study, genetic changes in ß-tubulin were seen in parasites obtained from patients exposed to repeated ivermectin treatment when compared with parasites obtained from the same patients before any exposure to ivermectin. Furthermore, the researchers found that the extent of the genetic changes was dependent on the level of ivermectin treatment exposure.
Ivermectin has been used for mass treatment of river blindness for up to 18 years and is currently the only safe drug available for mass treatment of the estimated 37 million people infected with the O. volvulus parasite. According to this study, the genetic selection shown “could have implications for the development of ivermectin resistance in O. volvulus and for the ongoing onchocerciasis control programmes.”
In a related commentary article, publishing the same day in PLoS Neglected Tropical Diseases, Sara Lustigman (New York Blood Center) and James McCarter (Washington University School of Medicine), who were not involved in Prichard and colleagues’ study, say that the study is “a wake-up call for onchocerciasis control programs to select their treatment regimens carefully and to develop plans for detecting ivermectin resistance and the associated genetic markers.”
These two articles are the first to be released by PLoS Neglected Tropical Diseases, the Public Library of Science’s newest journal. The journal will be the first publication devoted entirely to neglected tropical diseases such as elephantiasis, Chagas disease, leprosy, hookworm, schistosomiasis, and African sleeping sickness. All papers published in PLoS Neglected Tropical Diseases will be freely available online, and published under a license that allows readers to freely distribute and translate them and create derivative works.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
