Prevention, vaccines addressed at IAS conference

During the 5th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention meeting in Cape Town, South Africa, scientists "renewed the call for more immediate and urgent effort to be directed towards HIV prevention amid the dominance of treatment interventions and the world-wide search for a quick fix vaccine, which many agree, is years away," Health-e/allAfrica.com reports (Thom, 7/22).

Targeted nanoparticles boost arsenic’s anticancer punch

Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

Lancet Infectious Diseases examines spread of XDR-TB

The journal Lancet Infectious Diseases examines the worldwide spread of extensively drug-resistant tuberculosis (XDR-TB). Currently, about 500,000 of the 9 million new cases of TB that are identified each year are strains of XDR-TB. "Drug resistance is largely man-made - it is vitally important to review antibiotic treatment strategies and to ensure the Stop TB Strategy is fully applied to prevent further selection of drug-resistant mutants," Leonard Amaral of Universidade Nova de Lisboa said.

Measuring fragile X mental retardation

Researchers from the University of California, Davis have developed a specific and quantitative means of measuring levels of the fragile X mental retardation 1 (FMR1) protein (FMRP), which is mutated in fragile X syndrome. The related report by Iwahashi et al, "A quantitative ELISA assay for the fragile X mental retardation 1 protein," appears in the July 2009 issue of the Journal of Molecular Diagnostics.
