Following Felleman and Van Essen (1991), forward connections to agranular cortex are identified with terminal concentrations in layer 3, as ascending terminations in sensory cortex typically terminate in both this layer and layer 4 (see also Rozzi et al. 2006; Borra et al. 2008).
The ultimate units, Kant's sphaera activatis, are terminal concentrations of energy that stretch out as active dimensional spheres.
Half-life was calculated by linear least squares regression after logarithmic transformation of the terminal concentrations.
"Flip-flop" kinetics occurs when absorption is slower than elimination making terminal concentrations dependent on absorption, which becomes rate limiting.
Drugs with rate-limiting absorption show terminal concentrations after an extravascular dose with a longer half-life than i.v. data suggest.
To interpret this unexpected result, further research will be necessary to determine whether, in DLB, the DAT is a faithful marker of dopamine terminal density and dopamine concentration, or whether DAT levels and dopamine terminal density diverge.
It is important to note that at early timepoints, blood concentrations parallel plasma concentrations; however, during the terminal phase, concentrations of azithromycin in blood parallel concentrations of azithromycin in PBMCs and PMNs (which comprise a small fraction of total blood volume, but contain much higher azithromycin concentrations).
Since CP-690550 was administered via osmotic mini-pumps, the terminal drug concentration represents the steady-state drug concentrations in these animals.
When comparing the two fermentation runs using pH profiling pretreated whole slurry of FS-10, a longer acid application delay time of ti = 45 min slightly reduced terminal ethanol concentration (45.9 g/L) as well as ethanol yield (0.460 g/g sugar) compared with those achieved from ti = 25 min run of 48.9 g/L and (0.494 g/g sugar), respectively, (Table 3).
Relative to LY411575, a reference non-selective gamma-secretase inhibitor, ELN475516 demonstrated significant reduction of brain Aβ at the lowest dose tested (15 mg/kg/dose, b.i.d)., with no overt signs of toxicity at the highest dose tested (1,000 mg/kg/dose, b.i.d). at the end of the study, indicating an in vivo selectivity >65 based on dose as well as terminal compound concentration in plasma.
