The European Vaccine Effort against HIV/AIDS, today announced that a phase I clinical trial of novel investigational vaccines comprising DNA-HIV-C and NYVAC-HIV-C for the prevention of HIV infection has started in Lausanne and London in February 2005. These vaccines are based on HIV subtype C, which is prevalent in China, India and sub-Saharan Africa, and constitutes more than 50 percent of the new HIV infections worldwide.
The phase I clinical trial, with the EuroVacc Foundation as the sponsor, will evaluate the safety of DNA-HIV-C alone and of the prime-boost regimen of DNA-HIV-C+NYVAC-HIV-C, and to compare the immunogenicity of the prime-boost regimen to NYVAC-HIV-C alone in healthy volunteers at low risk of acquiring HIV infection. The study will recruit 40 healthy volunteers: 20 at the Centre Hospitalier Universitaire Vaudois (CHUV) in Lausanne, and 20 at St Mary’s Hospital, Imperial College London. All volunteers, male or female, should be between 18 and 55 yrs, HIV-negative and at low risk of infection.
The trial will carefully evaluate the safety and immunogenicity of the combination of the vaccines, in particular their ability to generate HIV-specific cell-mediated immune response to HIV, which is considered to be a key determinant of protection against infection. According to the principal clinical investigators Prof. Giuseppe Pantaleo of CHUV in Lausanne and Prof. Jonathan Weber of Imperial College London for the clinical studies, “if this study generates promising results, EuroVacc intends to further evaluate the vaccines in larger clinical trials.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
