A large number of river otter (Lontra canadensis) males were collected
from areas of high and low contaminant concentrations throughout western
Oregon and Washington during the fall and winter of 1994-99. Few significant
non-reproductive organ morphometric differences were found in the large series
of male otters collected, except for adrenal...
The thermodynamic properties of 39 PBDEs have been calculated using Gaussian 03
on the B3LYP/6-31G(d)//B3LYP/6-31G(d) level. The PBDE congeners' enthalpies of
formation increase with increasing number of bromines and show a strong dependence on
the bromine substitution pattern. The effects of bromine substitution pattern have been
quantitatively studied by GAM...
Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...
The role of synthesis and degradation in controlling enzyme
concentrations was studied.
Concentrations of chloride and arginine were determined for
blood and liver at various stages of development from the embryo to
the 8 day old chicken. The chloride concentrations were used to
obtain the volume of extracellular blood in...
The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...
