    Description: The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day, 560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with current propulsion systems and comparable shielding is found to be 0.66 +/- 0.12 sievert.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zeitlin, C -- Hassler, D M -- Cucinotta, F A -- Ehresmann, B -- Wimmer-Schweingruber, R F -- Brinza, D E -- Kang, S -- Weigle, G -- Bottcher, S -- Bohm, E -- Burmeister, S -- Guo, J -- Kohler, J -- Martin, C -- Posner, A -- Rafkin, S -- Reitz, G -- New York, N.Y. -- Science. 2013 May 31;340(6136):1080-4. doi: 10.1126/science.1235989.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Southwest Research Institute, Boulder, CO, USA. zeitlin@boulder.swri.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23723233" target="_blank"〉PubMed〈/a〉

    Description: GSK1265744 (GSK744) is an integrase strand-transfer inhibitor that has been formulated as a long-acting (LA) injectable suitable for monthly to quarterly clinical administration. GSK744 LA was administered at two time points 4 weeks apart beginning 1 week before virus administration, and macaques were challenged weekly for 8 weeks. GSK744 LA, at plasma concentrations achievable with quarterly injections in humans, protected all animals against repeated low-dose challenges. In a second experiment, macaques were given GSK744 LA 1 week before virus administration and challenged repeatedly until infection occurred. Protection decreased over time and correlated with the plasma drug levels. With a quarterly dosing schedule in humans, our results suggest that GSK744 LA could potentially decrease adherence problems associated with daily preexposure prophylaxis (PrEP).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4308974/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4308974/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andrews, Chasity D -- Spreen, William R -- Mohri, Hiroshi -- Moss, Lee -- Ford, Susan -- Gettie, Agegnehu -- Russell-Lodrigue, Kasi -- Bohm, Rudolf P -- Cheng-Mayer, Cecilia -- Hong, Zhi -- Markowitz, Martin -- Ho, David D -- 1DP1-DA033263/DA/NIDA NIH HHS/ -- 2P51-OD11104-52/OD/NIH HHS/ -- P51 OD011104/OD/NIH HHS/ -- R0-AI100724/AI/NIAID NIH HHS/ -- R01 AI100724/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 7;343(6175):1151-4. doi: 10.1126/science.1248707.

    Description: The Radiation Assessment Detector (RAD) on the Mars Science Laboratory's Curiosity rover began making detailed measurements of the cosmic ray and energetic particle radiation environment on the surface of Mars on 7 August 2012. We report and discuss measurements of the absorbed dose and dose equivalent from galactic cosmic rays and solar energetic particles on the martian surface for ~300 days of observations during the current solar maximum. These measurements provide insight into the radiation hazards associated with a human mission to the surface of Mars and provide an anchor point with which to model the subsurface radiation environment, with implications for microbial survival times of any possible extant or past life, as well as for the preservation of potential organic biosignatures of the ancient martian environment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hassler, Donald M -- Zeitlin, Cary -- Wimmer-Schweingruber, Robert F -- Ehresmann, Bent -- Rafkin, Scot -- Eigenbrode, Jennifer L -- Brinza, David E -- Weigle, Gerald -- Bottcher, Stephan -- Bohm, Eckart -- Burmeister, Soenke -- Guo, Jingnan -- Kohler, Jan -- Martin, Cesar -- Reitz, Guenther -- Cucinotta, Francis A -- Kim, Myung-Hee -- Grinspoon, David -- Bullock, Mark A -- Posner, Arik -- Gomez-Elvira, Javier -- Vasavada, Ashwin -- Grotzinger, John P -- MSL Science Team -- New York, N.Y. -- Science. 2014 Jan 24;343(6169):1244797. doi: 10.1126/science.1244797.
