The nickel II) in borate medium gives one or two waves depending on its concentration as well as the medium composition.
We have previously shown that AtRA directly suppresses IL-12-dependent differentiation of naïve CD4+ T cells to Th1 cells, and enhances or suppresses IL-4-dependent differentiation to Th2 cells depending on its concentration and the timing of its addition [27].
Our data document for the first time that FasL can induce in vitro both BM MSC proliferation and apoptosis depending on its concentration and, more importantly, that it inhibits their differentiation into adipocytes.
30 Itraconazole is a triazole antifungal agent against Trichophyton and Microsporum spp. It exhibits both fungistatic and fungicidal activity depending on its concentration in the tissues, though its primary mode of action is fungistatic by inhibiting the cytochrome P-450-dependent enzymes, blocking the synthesis of ergosterol, the principal component of fungal cell membranes.
The virulence of M. ulcerans is dependent on mycolactone, a lipid toxin with cytotoxic or immunosuppressive properties depending on its concentration [ 1- 6].
Because ROS can also activate both cell survival and apoptotic pathways depending on its concentration and localization, regulation of ROS by H2AX may be one mechanism to determine cell survival or apoptosis after DNA insults.
Depending on its concentration, nitric oxide (NO) has beneficial or toxic effects.
And either smectite or chlorite results upon the addition of magnesium, depending on its concentration.
By these means, PGE2 can act as a regulatory switch of immune responses depending on its concentration in the microenvironment.
NO plays a dual role on growth and survival of PFs depending on its concentration in the culture medium.
H2O proves to influence in opposite manners the chlorobenzene conversion depending on its concentration and on the kind of catalysts.
