An outbreak of lymphogranuloma venereum has been detected following reports of the disease in Europe. “From October 2004 to the end of April 2007, 492 cases of lymphogranuloma venereum were diagnosed in the UK. These cases were predominantly in men who have sex with men and many of the patients were also infected with other STIs, particularly with HIV,” says Professor Catherine Ison from the Health Protection Agency Centre for Infections in London.
Until recently doctors saw very few cases of lymphogranuloma venereum in the UK, Europe and other developed countries. The disease is caused by certain strains of the bacterium Chlamydia trachomatis and required new diagnostic tests, that had previously not been available in the UK, before the outbreak could be detected.
Bacteria evolve all the time, and the new sexually transmitted bacterial diseases including this new variant of Chlamydia trachomatis are presenting fresh challenges in diagnosis to medical support teams.
“Microbiologists want to be more proactive in helping patients with STIs,” says Professor Ison. “We have made advances in diagnosis by using molecular tests such as the nucleic acid amplification tests (NAATs) which give us a more accurate results, faster turnaround times and can be used with non-invasive samples. These tests can be used for screening in specialised sexual health care clinics and in primary care. However they need to be carefully validated before use.”
“While the advances in technology have enabled progress in many areas, the new tests should only be used by experts who understand their advantages and disadvantages and can interpret the test results properly”, says Professor Ison. “We are very concerned that some of the new tests are being offered for sale over the internet, for home use, when they should really only be used in clinics”.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
