The experiments are performed with 3, 5, or 8 parallel devices exposed either to the same solution or to different sample concentrations.
Auto-recovery pattern of altered protein levels was also studied in a parallel group exposed to MCP (10−5 M) for 6 h followed by 18 h incubation in fresh culture medium without MCP.
Staining for p24 was absent when an inhibitory concentration AZT was included in a parallel culture exposed to the X4 virus, showing that the observed staining required active reverse transcription and that the p24 signal was not due to passively adsorbed protein from the input virus.
Parallel cultures exposed to oxygenated sham medium were used as controls.
In parallel, BMSPCs exposed to S1P demonstrated functional endothelial lineage commitment as demonstrated by 10-fold higher tube formation in matrigel assays (P < 0.05) and 4(f)).
Data are expressed as a percentage of total neuronal LDH activity (defined as 100%), which was determined in each experiment by assaying the supernatant of parallel cultures exposed for 16 18 h to 75 or 100 μM glutamate.
In parallel, we exposed our U937 cell lines to TNF- α, expecting similar protection, as Fas is a member of the tumour necvosis factor (TNF) receptor superfamily (Itoh et al, 1991; Oehm et al, 1992), and shares common signalling pathways with the type 1 TNF receptor (Hsu et al, 1996), including in U937 cells (Schütze et al, 1992; Cifone et al, 1993).
This tool highlights computation and communication imbalance in parallel programs, exposing portions of program code which are amenable to improvement.
Samples were collected from each cell line before any asbestos exposure or treatment (0h), from asbestos-exposed and control (not exposed, parallel cultures) A549 and Beas-2B cells at 1h, 6h, 24h, and 48h, with additional 7 days for A549.
A complex body is used as a steel catalyst and exposed parallel to a gas flow.
