WHO’s objective is to enable 3 million people living with HIV to have access to antiretroviral treatments by 2005. The development of simple and inexpensive generic fixed-dose combined therapies appears the most suitable solution for making possible this access to treatments in developing countries with meagre resources.
The tritherapies that associate two different classes of antiretrovirals (two inverse transcriptase nucleoside inhibitors and a non-nucleosidic inhibitor of this same viral enzyme), used as a basic treatment, are effective and well tolerated. Their combined form in a single tablet, developed by a firm producing generic drugs, encourages better treatment compliance by the patient and simplifies management of orders and storage of the medicines. Their cost is much lower than that of tritherapies of patented medicines (2).
Consequently, these combined generic forms provide the possibility of treating more subjects infected with HIV. However, although prequalified by WHO and available in many developing countries, at present some international aid agencies involved in programmes of access to antiretrovirals do not recognize them. The main reason cited is the absence of full clinical studies that could allow assessment of their effectiveness, safety and quality.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
