Moreover, chemical analysis allowed us to identify a certain number of commonly found, highly water-soluble, low-molecular-weight compounds, several of which (glycerol, uracil, thymine, uridine, thymidine) were able to induce attraction when tested individually but at concentrations substantially higher than those found in nature.
Four of the eight subjects in the control group exhibited exenatide plasma concentrations substantially higher (Cmax 960 1996 pg ml−1) than expected due to exenatide clearance being substantially lower (CLp/F 2.13 3.16 l h−1) than expected.
Levels of 1-NAP were lower than reported adult reference range concentrations, whereas TCPy concentrations were substantially higher.
We extended this research to 50 homes in northern California and found that indoor air concentrations were substantially higher than outdoor concentrations for most of the 104 SVOCs measured, indicating that indoor sources dominate total exposure.
The obtained ion concentrations (CSF: 150 ± 1 mM Na+, 3 ± 0 mM K+, 100 ± 6 mM Cl− and in the choroid plexus epithelial cells: 31 ± 5 mM Na+, 141 ± 12 mM K+, and 35 ± 9 mM Cl−, n = 4) illustrate that the intracellular Na+ and Cl− concentrations are substantially higher than the 5−15 mM range usually observed in most mammalian cells34.
For example, in California's Central Valley, one of the most productive agricultural areas in the world, pesticide concentrations are substantially higher in small creeks dominated by irrigation return flows, as compared to main streams where the majority of flow originates in Sierra Nevada mountains [3], [4], [5], [6].
However, plasma glucose concentrations were substantially higher in diabetic than in nondiabetic subjects.
On the laboratory day, however, MZ correlations for the three morning cortisol concentrations were substantially higher than those of the DZ pairs.
These concentrations are substantially higher than those (1) predicted by models based on normal consumer use of pharmaceuticals (34), (2) modeled for a PFF in Switzerland (22), and (3) cited as representative of maximum WWTP effluent concentrations (35).
Akt appears to be differentially regulated in high and low oxidative muscles, as it has been shown that both total and phosphorylated Akt concentrations were substantially higher in rat soleus compared to EDL (Sakamoto et al. 2002).
The fact that styrene concentrations were substantially higher in the children is unexpected, particularly because styrene is one of several VOCs known to be elevated in smokers' blood (Ashley et al. 1996; Churchill et al. 2001; Wallace et al. 1987).
