Heat-denatured p24 Antigen Tests Can Cut Cost of HIV Progression Monitoring
Researchers at the Johns Hopkins Bloomberg School of Public Health and the University of Zurich, Switzerland, have identified a test for monitoring the progression of HIV in the early stages of the disease that is less expensive than current tests used to monitor the progression of HIV. The test, called HIV-1 protein 24 (p24) antigen, predicts disease progression as well as CD4 lymphocyte count and HIV-1 RNA viral load, the measurements currently used to determine when patients should start antiviral drug therapy to prevent AIDS. The study, “Heat-Denatured Human Immunodeficiency Virus Type 1 Protein 24 Antigen: Prognostic Value in Adults with Early-Stage Disease,” appears in the Oct. 15 issue of The Journal of Infectious Diseases.
Timothy R. Sterling, MD, a study co-author and assistant professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health said, “The test could be used to determine when to initiate anti-retroviral therapy in HIV-infected persons. And because it costs much less than both CD4 lymphocyte count and HIV-1 RNA viral load, the heat-denatured p24 antigen test could be of particular benefit in developing countries, where the burden of HIV infection is great.”

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
