Deschampsia antarctica Desv., Colobanthus quitensis (Kunth) Bartl., and Polytrichum …

Residual effect of UV radiation on Microcystis aeruginosa and Escherichia coli K12 A/λ (F+)
was studied under various conditions to examine if the formation of hydrogen peroxide …

Desiccation resistance and a high intracellular Mn/Fe ratio contribute to ionizing radiation
resistance of Deinococcus radiodurans. We hypothesized that this was a general …

Extremophiles are a rich source of novel secondary metabolites and valuable antioxidative
compounds. Here, we examined the antioxidative capacities of aqueous extracts derived …

Radiation‐resistant bacteria have garnered a great deal of attention from scientists seeking
to expose the mechanisms underlying their incredible survival abilities. Recent analyses …

Ultraviolet (UV) radiation induces DNA damage, oxidative stress, and inflammatory
processes in human epidermis, resulting in inflammation, photoaging, and …

Knowledge of the molecular effects of UV radiation (UVR) on bacteria can contribute to a
better understanding of the environmental consequences of enhanced UV levels associated …

Chronic exposure to ultraviolet B (UVB) irradiation is a major cause for skin photoaging.
UVB induces damage to skin mainly by oxidative stress, inflammation, and collagen …

Isolation of five ionizing radiation (IR)-resistant bacteria by screening of isolates from various
habitats classified as common and stressed is reported. IR-resistant isolates exhibited …

All organisms on earth grow under the influence of a natural and relatively constant dose of
ionizing radiation referred to as background radiation, and so cells have different …
