Fig. 18.2 CaMKII-6 isoform expression and distribution in neonatal rat cardiomyocytes (CM) and cultured rat aortic vascular smooth muscle (VSM) cells. The photomicrographs depict d-isozyme distribution assessed by indirect immunofluorescence (IF) using an antibody specific for the alternatively spliced 6-subunit C-terminus (CK26c-term see Figure 18.1). The immunoblot (IB) with the same antibody 6-subunit variants expressed in the cells. Two protein loadings were used for each cell lysate. The major subunits were identified by RT-PCR in previously published studies (Schworer et al. 1993).

Different safety factors may have been used in the derivation of the reference values of the individual substances (RfDA deterministic HI thus sums risk ratios that may reflect different percentile values of a risk probability distribution. Assessment and interpretation of the uncertainty in the HI may be severely hampered by this summation of dissimilar distribution parameters. In a probabilistic risk assessment, the uncertainty in the exposure and reference values is often characterized by lognormal distributions. The ratio of 2 lognormal distributions also is a lognormal distribution. The variance in a quotient of 2 random variables can be approximated as follows (Mood et al. 1974, p 181) ...

The charge distribution deduced from the esca data implies that the dipole moment for trifluoromethylbenzene is 1.49 D with the fluorine atoms at the negative terminus (48). This value is only about 50% of the known dipole moment. This is apparently a common problem. Often the charge distributions assessed in the analysis of the esca results do not correspond with known dipole moments. Most explanations focus on the idea that molecular dipole moments are especially sensitive to the distribution of lone pair electron density whereas the core ionization potentials depend more critically on the charge distribution in the vicinity of the nucleus (48). Nevertheless, the discrepancy between the estimated and known moments is disconcerting.

The concept of expected utility is utilised to generate numerical values equivalent to the distributed assessment of the top-level criterion or goal of each alternative for ranking in order to obtain the probable risk level of disruption for decision making.

By employing, the semiempirical quantum mechanical method AMI, the molecular geometries of the arylalkanoic acids, indomethacin, naproxen, and ibuprofen, were optimized and their frontier orbital charge distributions assessed. Afterward, these molecular parameters were matched in order to recognize structure-activity relationships. Bearing in mind these evaluations. 

Sampling frequency depends on the rate/extent of dermal absorption. Appropriate analytical techniques, e.g. scintillation counting, HPLC or GC, should be used. Their validity, sensitivity and detection limits should be documented in the report. When an increase in sensitivity is needed, the test substance should, whenever possible, be radiolabeUed. Qualitative or semi-quantitative methods such as microautoradiography can be useful tools for skin distribution assessments.
