  • Characterization of different DNA repair pathways in hepatic cells of Zebrafish (Danio rerio). [Journal Article]
    DNA Repair (Amst) 2019; 83:102695Costa SR, Velasques RR, … Sandrini JZ
  • The concern about DNA damage has directed efforts toward evaluating the genotoxic potential of physical and chemical agents. Since the extent of DNA damage is also related to the capacity of the organism in repairing the DNA, the advance of toxicological studies on this area depends on the characterization of the DNA repair mechanisms in the available models. The cellular zebrafish models, for ex…
  • Mechanisms investigation on bacterial inactivation through combinations of UV wavelengths. [Journal Article]
    Water Res 2019; 163:114875Song K, Mohseni M, Taghipour F
  • Recently, ultraviolet light-emitting diodes (UV-LEDs) have emerged as a new UV source, bringing flexibility for various UV wavelength combinations due to their unique feature of wavelength diversity. In this study, we investigated inactivation mechanisms of representative microorganisms at different wavelength combinations using UV-LEDs. Two types of indicator microorganisms were examined, namely…
  • DNA Damage Response Pathways in Dinoflagellates. [Journal Article]
    Microorganisms 2019; 7(7)Li C, Wong JTY
  • Dinoflagellates are a general group of phytoplankton, ubiquitous in aquatic environments. Most dinoflagellates are non-obligate autotrophs, subjected to potential physical and chemical DNA-damaging agents, including UV irradiation, in the euphotic zone. Delay of cell cycles by irradiation, as part of DNA damage responses (DDRs), could potentially lead to growth inhibition, contributing to major e…
  • Extensive loss of cell-cycle and DNA repair genes in an ancient lineage of bipolar budding yeasts. [Journal Article]
    PLoS Biol 2019; 17(5):e3000255Steenwyk JL, Opulente DA, … Rokas A
  • Cell-cycle checkpoints and DNA repair processes protect organisms from potentially lethal mutational damage. Compared to other budding yeasts in the subphylum Saccharomycotina, we noticed that a lineage in the genus Hanseniaspora exhibited very high evolutionary rates, low Guanine-Cytosine (GC) content, small genome sizes, and lower gene numbers. To better understand Hanseniaspora evolution, we a…
  • Microorganisms inactivation by wavelength combinations of ultraviolet light-emitting diodes (UV-LEDs). [Journal Article]
    Sci Total Environ 2019; 665:1103-1110Song K, Taghipour F, Mohseni M
  • Ultraviolet light-emitting diode (UV-LED) is an emerging UV source with many special features due to the nature of semiconductor devices. One such feature is wavelength diversity that does not exist in conventional mercury based UV lamps, which provides opportunities to selectively combine multiple wavelengths for potentially additional effects by UV-LEDs. In this work, the inactivation of differ…
