Sabrina Fröls,Paul M. K. Gordon,Mayi Arcellana Panlilio,Iain G. Duggin,Stephen D. Bell,Christoph Wilhelm Sensen,Christa Schleper +6 more
TL;DR: In this paper, high-density DNA microarrays were used to characterize the genome-wide transcriptional response of the hyperthermophilic, aerobic crenarchaeote Sulfolobus solfataricus to UV damage.

Desiccation as a long-term survival mechanism for the archaeon Methanosarcina barkeri.
TL;DR: After desiccation M. barkeri has the innate capability to survive extended periods of exposure to air and lethal temperatures, and the protection mechanisms are likely adequate to maintain cell viability during periodic exposure events.

Low-dose carbon ion irradiation effects on DNA damage and oxidative stress in the mouse testis
TL;DR: In this paper, the effects of low-dose carbon ion irradiation on reproductive system of mice were investigated by measuring DNA double-strand breaks (DNA DSBs) and oxidative stress parameters including malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, and testis weight and sperm count at 12h, 21d and 35d after irradiation in mouse testis.

Radiation Induced DNA Double Strand Break Studies of a Metal Sensitive Novel Bacterial Isolate from East Calcutta Wetland
TL;DR: The strain was one of the members of the group of uncultivated bacterium as evident from phylogenetic analysis, thus indicating the successful cultivation of an as yet uncultivable novel microbe and also the non-specific growth of microbes in prescribed medium.

Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
TL;DR: It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms.

Phylogenetic structure of the prokaryotic domain: The primary kingdoms
Carl R. Woese,George E. Fox +1 more
TL;DR: A phylogenetic analysis based upon ribosomal RNA sequence characterization reveals that living systems represent one of three aboriginal lines of descent: the eubacteria, comprising all typical bacteria, the archaebacteria, and the urkaryotes, now represented in the cytoplasmic component of eukaryotic cells.
Journal ArticleDOI
Clustered DNA damages induced in isolated DNA and in human cells by low doses of ionizing radiation
TL;DR: It is shown that ionizing radiation does induce clustered DNA damages containing abasic sites, oxidized purines, or oxidized pyrimidines, and even low doses (0.1-1 Gy) of high linear energy transfer ionizing Radiation induce clustered damages in human cells.
