Together, these results show, for the first time, an efficient association between alpha and beta therapies, which could become a promising tool in the control of tumor progression.Īlpha–beta therapy bone cancer nanomicelles radioactive gold nanoparticles radium-223 dichloride. We observed a significant increase in tumor cell death using combined alpha and beta therapy in the same formulation, compared with these components used alone. Furthermore, nanomicelles were tested in an in vitro cytotoxicity assay. Ra nanomicelles co-loaded with AuNPs, with simultaneous alpha and beta emission, showed no instability, a mean particle size of 296 nm, and a PDI of 0.201 (☐.096). For this, we synthesize and characterize nanomicelles, as well as analyze some parameters, such as particle size, radioactivity emission, dynamic light scattering, and microscopic atomic force. In this context, this study aims to analyze the antitumoral effects of Ra nanomicelles co-loaded with radioactive gold nanoparticles (AuNPs). Nanotechnology, including several radioactive nanoparticles, can be safely and effectively used in cancer treatment. Radium-223 ( 223Ra), an alpha emitter, promotes localized cytotoxic effects, while radioactive gold ( 198Au), beta-type energy, reduces radiation in the surrounding tissues. 7 Laboratory of Radiopharmacy and Nanoradiopharmaceuticals, Zona Oeste State University, Rio de Janeiro 23070-200, Brazil.Īlpha and beta particulate radiation are used for non-treated neoplasia, due to their ability to reach and remain in tumor sites.6 Instituto de Ciências Biomédicas, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941-902, Brazil.5 Center for Nanotechnology in Drug Delivery, Eshelman School of Pharmacy, Division of Pharmacoengineering and Molecular Pharmaceutics, University of North Carolina at Chapel Hill, Chapel Hill, NC 27599, USA.4 Laboratory of Biophysics and Nanosystems, Department of Physics, Federal University of Maranhão, São Luís 65080-805, Brazil.3 DEFARMED Laboratory, Faculdade de Farmácia, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941-900, Brazil.The community sits in the mountains along an isolated stretch of Colorado River downstream from Gore Canyon and southwest of Kremmling. 2 Laboratory of Nanoradiopharmaceuticals and Synthesis of Novel Radiopharmaceuticals, Nuclear Engineering Institute, Brazilian Nuclear Energy Commission, Rio de Janeiro 21941-906, Brazil. Radium, elevation 6,890 feet (2,100 m), 1 is a small rural unincorporated community in southwestern Grand County, Colorado, United States.1 Argonauta Nuclear Reactor Center, Nuclear Engineering Institute, Brazilian Nuclear Energy Commission, Rio de Janeiro 21941-906, Brazil.Safety is our first concern on the river, closely followed by fun and excitement. Helmets and wetsuits are provided in heavier rapids. A thorough briefing on whitewater safety procedures is given prior to the rafts entering the river. Each participant wears a fitted, Coast Guard approved Type V whitewater life jacket at all times on the river. Each raft is guided by a skilled, certified professional. Safety is our primary focus on each of our COLORADO WHITEWATER RAFTING adventures. Established in 1973, we are among the most experienced rafting companies in Colorado. From wild whitewater that will test your cool, and cool backwaters that will cool your jets, we’re here to take you there.ĬOLORADO RIVER RUNS is the only locally owned rafting outfitter on the upper reaches of the COLORADO RIVER. What started as a giant wild goose chase turned into quite possibly one of the most unexpected moments in Radio 1’s history. From the rambunctious rapids of the EAGLE RIVER to the fun WHITEWATER and deep canyons of the COLORADO RIVER, let COLORADO RIVER RUNS guide you there. COLORADO RIVER RUNS is here to guide you to the best of COLORADO WHITE WATER RAFTING.
