A new anti-herpes agent derived from a common herb effectively treats and prevents the disease in animals. Researchers from Dalhousie University in Nova Scotia present their data today at the 103rd General Meeting of the American Society for Microbiology.
"Prunella vulgaris [also known as self-heal] is a perennial plant commonly found in China, the British Isles, Europe, and North America. In herbal literature, P. vulgaris has been described as a hot water infusion to treat sores in the mouth and throat, as an astringent for internal and external purposes, as a crude anti-cancer drug, and as a herbal remedy to lower high blood pressure," says Song Lee, one of the researchers on the study.
Lee and his colleagues extracted a lignin-carbohydrate compound from the plant, which was incorporated into a topical cream and tested on mice and guinea pigs with experimental herpes simplex virus-1 (HSV-1) and herpes simplex virus-2 (HSV-2) infections. Guinea pigs receiving the lignin-carbohydrate complex cream treatment showed a significant reduction in skin lesions compared to those that received no treatment. Mice receiving the lignin-carbohydrate complex cream treatment showed a significant increase in survival rate compared to animals that received no treatment.

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...
