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”.

To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the...
Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating....
Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
