Incidence of acute myeloid leukemia and hepatocellular carcinoma in mice irradiated with 1 GeV/nucleon (56)Fe ions.

30 Jul 2009 Abstract Estimates of cancer risks posed to space-flight crews by exposure to high atomic number, high-energy (HZE) ions are subject to considerable uncertainty because epidemiological data do not exist for human populations exposed to similar ... Read more...

Response of extracellular matrix regulators in mouse lung after exposure to photons, protons and simulated solar particle event protons.

29 Jun 2009 This study compared the effects of photons (gamma rays), protons and simulated solar particle event protons (sSPE) on the expression of profibrotic factors/extracellular matrix (ECM) regulators in lung tissue after whole-body irradiation. TGF-beta1, ... Read more...

Musculoskeletal changes in mice from 20-50 cGy of simulated galactic cosmic rays.

29 Jun 2009 On a mission to Mars, astronauts will be exposed to a complex mix of radiation from galactic cosmic rays. We have demonstrated a loss of bone mass from exposure to types of radiation relevant to space flight at doses of 1 and 2 Gy. The effects of ... Read more...
