A multi-centre research team from the UK and the USA has discovered the first method to deliver medication directly into the encysted stage of the infectious parasites that cause toxoplasmosis and a novel target for medicines in the parasite. It has major implications for the way that we treat this devastating disease as it could lead to new medications and approaches to better tackle it. The study will be published online on November 17 by the Proceedings of the National Academy of Sciences (PNAS).
Toxoplasmosis is a parasitic infection from the apicomplexan family, which includes the causes of malaria and cryptosporidiosis. The disease is caused by a single celled organism called Toxoplasma gondii and is spread by cats and by eating undercooked meat. Toxoplasmosis is a common disease and can cause devastating problems for those with weakened immune systems, or when transmitted from mother to unborn child. It can lead to blindness, retardation and even death.
Professor David Rice, from the Department of Microbiology and Biotechnology at the University of Sheffield, was involved in the study. He explains, "Toxoplasma infections are especially difficult to treat because they recur. The disease operates in two stages, a proliferative stage and a latent stage. During the proliferative stage the infection can be treated, although there are many problems with available medicines, but the illness then progresses to a latent stage, where the cysts form that hold the parasites in a less active state. These cysts are untreatable as scientists cant get medication inside the cyst. The cysts eventually rupture and release proliferating parasites, which can cause a recurrence of the illness if the immune system is weakened and in those with eye disease. Such recurrences can cause severe damage to the eye and nervous system."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
