By monitoring the thermo-mechanical properties upon UV illumination, a distinctive depletion of storage modulus and glass transition temperature is observed with increasing exposure dose.
However, Morgan et al. (2002, 2006) showed that, in the brains of neonates perinatally exposed to Hg vapor (1, 2, 4, or 8 mg/m for 2 hr/day during GD6 GD15), total Hg concentrations increased with increasing exposure dose.
An increased exposure time or dose of the DDA allows or increase the contrast sensitivity to values higher than reachable with industrial films [3, 10].
Owing to the potential for increased exposure to dexamethasone, the dexamethasone dose in the NK1 arms was reduced to achieve exposure similar to that in the PALO group.
As expected, the density of side chains fades with increasing exposure and dose deposited on the sample.
The peroxidation of membrane lipids also increased with increasing SeMet exposure dose.
The cellular lipid peroxidation tended to increase with increasing selenite exposure dose, indicating the occurrence of membrane damage.
These results suggest that differential expression of photosystem genes under stress, and that in C. polykrikoides the photosystem apparatus (e.g., PS I and PS II) may be experience ongoing damage with increasing exposure time and doses of CuSO4.
Spectral analysis based on cell ROIs showed that spectra red-shifted with increasing exposure time and NP exposure dose (Figure 4). Figure 5 shows representative HS images, corresponding spectra, and cellular TEM images to illustrate the progression of changes observed in HS images, spectra, and cellular TEM images after 2, 5, 10, and 24 h of NP exposure at the 24 μg/mL dose.
