But the stem cells also appeared to model the generation - to - generation repeat expansion seen in human patients. (scripps.edu)
It's also the first time that anyone has created a model system to study the triplet repeat expansion phenomenon in patients» own genes.» (scripps.edu)
Fe — S — C systematics for the Late Permian to Early Triassic show that anoxic non-sulfidic (ferruginous), rather than euxinic, conditions were prevalent, and reveal a dynamic history of repeated expansion of ferruginous conditions from anoxia focussed on the distal slope, as well as short - lived episodes of oxia that supported diverse biota.
