Biological effects of space environmental factors: A possible interaction between space radiation and microgravity
Publication date: Available online 1 November 2018Source: Life Sciences in Space ResearchAuthor(s): Fumio Yatagai, Masamitsu Honma, Naoshi Dohmae, Noriaki IshiokaAbstractIn the mid-1980s, space experiments began to examine if microgravity could alter the biological effects of space radiation. In the late 1990s, repair of DNA strand breaks was reported to not be influenced by microgravity using the pre-irradiated cells, because the exposure doses of space radiation were few due to the short spaceflight. There were, however, conflicting reports depending on the biological endpoints used in various systems. While almost no at...

Genetic Variation and Radiation Quality Impact Cancer Promoting Cellular Phenotypes in Response to HZE exposure
Publication date: Available online 21 October 2018Source: Life Sciences in Space ResearchAuthor(s): Deepa M. Sridharan, Shiena Enerio, Chris Wang, Mark A. LaBarge, Martha R. Stampfer, Janice M. PluthAbstractThere exists a wide degree of genetic variation within the normal human population which includes disease free individuals with heterozygote defects in major DNA repair genes. A lack of understanding of how this genetic variation impacts cellular phenotypes that inform cancer risk post heavy ion exposure poses a major limitation in developing personalized cancer risk assessment astronauts. We initiated a pilot study wit...

Dose calculations in a cell monolayer for high-throughput irradiation with proton beams generated by PW lasers for space applications
Publication date: Available online 20 October 2018Source: Life Sciences in Space ResearchAuthor(s): Mariana Bobeica, Sohichiroh Aogaki, Theodor Asavei, Mihail O. Cernaianu, Petru Ghenuche, Dan StutmanAbstractOne of the specific properties of laser-driven radiation is a broadband energy spectrum, which is also a feature of the space radiation fields. This property can be used in materials science studies or radiobiology experiments to simulate the energy spectrum of space radiation exposures in a ground-based laboratory. However, the differences in effects between the higher dose rates of laser generated radiation and the l...

LED lighting optimization as applied to a vitamin space plant growth facility
Publication date: Available online 27 September 2018Source: Life Sciences in Space ResearchAuthor(s): Yu.A. Berkovich, I.O. Konovalova, A.N. Erokhin, S.O. Smolyanina, V.G. Smolyanin, O.S. Yakovleva, I.G. Tarakanov, T.M. IvanovAbstractAn algorithm of determining optimal LED lighting parameters for leafy crops (Chinese cabbage Brassica chinensis L. was taken as a model) in a vitamin space Plant Growth Facility is proposed. The lighting parameters to optimize were the level of photosynthetic photon flux density (PPFD), red and white LEDs PPFD ratio and pulse repetition period with a fixed pulse length 30 µs. Optimal lighti...

Reduction of Geomagnetic Field (GMF) to Near Null Magnetic Field (NNMF) Affects Arabidopsis thaliana Root Mineral Nutrition
Publication date: Available online 1 September 2018Source: Life Sciences in Space ResearchAuthor(s): Ravishankar Narayana, Judith Fliegmann, Ivan Paponov, Massimo E. MaffeiAbstractThe Earth magnetic field (or geomagnetic field, GMF) is a natural component of our planet and variations of the GMF are perceived by plants with a still uncharacterized magnetoreceptor. The purpose of this work was to assess the effect of Near Null Magnetic Field (NNMF, ∼35 μT) on Arabidopsis thaliana Col0 root ion modulation. A time-course (from 10 min to 96 h) exposure of Arabidopsis to NNMF was compared to GMF and the content of some cation...

Irradiation effects of MeV protons on dry and hydrated Brassica rapa seeds
Publication date: Available online 21 August 2018Source: Life Sciences in Space ResearchAuthor(s): Naresh T. Deoli, Karl H. HasensteinABSTRACTAlthough space radiation is a known risk for space travel and eventual colonization of Moon or Mars, relatively few data exist on radiation effects on potential crop plants. We studied Brassica rapa to assess the tolerance of seeds and seedlings to radiation by exposing dry and hydrated B. rapa seeds to 1, 2 and 3 MeV proton ions of various fluences and examined the effect on germination and root growth. Modeling penetration depth with SRIM code indicated that the applied energy was ...
