Highlights from the 22nd International AIDS Conference (AIDS 2018), 22-27 July 2018, Amsterdam, the Netherlands.

Important data on the social, epidemiological and clinical aspects of HIV-1, comorbidities and hepatitis as well as data on novel antiretroviral agents and the cure agenda were presented at AIDS 2018. This report covers some of the highlights.

Evaluation of handheld assays for the detection of ricin and staphylococcal enterotoxin B in disinfected waters.

Development of a rapid field test is needed capable of determining if field supplies of water are safe to drink by the warfighter during a military operation. The present study sought to assess the effectiveness of handheld assays (HHAs) in detecting ricin and Staphylococcal Enterotoxin B (SEB) in water. Performance of HHAs was evaluated in formulated tap water with and without chlorine, reverse osmosis water (RO) with chlorine, and RO with bromine.

U.S. Military HIV Research Program: successfully integrating HIV vaccine research with prevention, care, and treatment.

In 1986, Congress mandated the U.S. Military HIV Research Program (MHRP) to protect service personnel and serve the global community by reducing the risk of HIV-1 infection.

Ricin activity assay by direct analysis in real time mass spectrometry detection of adenine release.

Biotoxin activity assays typically involve multistep sample preparation, multicomponent reactions, multistep analysis, or a combination thereof. We report a single-step, real-time ricin activity assay that requires little or no sample preparation and employs direct analysis in real time mass spectrometry. The release of adenine from the inhomogeneous substrate herring sperm DNA by ricin was determined to be 53 +/- 2 pmol adenine per picomole of ricin per hour.
