This is attributed to two different mechanisms: the instability of Al-containing sorbents (e.g. Al hydroxides) at low pH (in the topsoil), and the acid-mediated dissolution of apatite (the subsoil).
Thus, in the absence of interactions between Sgs1 and Mlh1/Top3, Top3-mediated dissolution of these unequal recombination intermediates cannot be carried out.
The notion that fragmented mitochondria are detrimental probably derives from early observations that mitochondria networks undergo fission-mediated dissolution during apoptosis, linking the process of mitochondrial fission to programmed cell death (Suen et al, 2008).
In summer, when the pore waters are sulfidic, AEF concentrations are at their lowest, presumably due to either chemically- or microbially-mediated reductive dissolution of Fe(III).
If this material is buried or submerged, however, microbially-mediated reductive dissolution of the Fe3+-bearing phases could result in re-mobilization of As.
SrtA-mediated dissolution affected only 1 of 31 cytokines and growth factors assayed, whereas standard protease degradation methods destroyed about half of these same molecules.
Under anoxic, slightly acidic conditions, microbially mediated iron III) reduction and subsequent dissolution of schwertmannite and jarosite were triggered by liberating Fe2+, SO42− and alkalinity to the incubating water.
That dissolution-of-youth thing was super-appealing.
Simultaneous addition of tPA caused initial clot formation followed by dissolution of fibrin induced by tPA-mediated conversion of plasminogen to plasmin (curve 2, Figure 5A C); the midpoint of fibrinolysis was between 6 to 7 min in each case.
For the overall performance of AQDS-mediated reductive dissolution on As V) and Fe III), a more positive effect resulting from 0.05 mM AQDS was observed compared to 0.10 mM, whereas an inhibitory effect was observed with 1.00 mM.
Possible explanations for the decrease in reducible Fe and its complexed As with depth include historic flushing of As and Fe from hydrous ferric oxides (HFO) by microbially-mediated reductive dissolution and aging of HFO to crystalline phases.
