In assessing the effect it was assumed, that with increasing BAL (or increasing competition), light would become a growth-limiting factor.
An AvaSpec-3648 UV-Vis spectrometer using an AvaLight-DH-S-BAL combined deuterium-halogen light source (both from Avantes, Apeldoorn, The Netherlands) was connected to a laptop to acquire spectra and monitor specific wavelengths throughout the experiment.
A large gallery entitled "Modern Life" is awash with colour, flanked by two large paintings, "Electric Prisms" and "Le Bal Bullier", which in their light and movement brilliantly evoke the speed and intensity of this new, electric era.
Light microscopic images of BAL cytospins confirmed that changes in the relative percentage of BAL cells were due to a significant increase in neutrophils produced by treatment with MWCNTs (data not shown).
CPE was visualized by light microscopy and BAL-treated cells were scored as the dilutions of sample giving 50% protection from virus as compared to a standard curve of IFNβ-treated cells.
The other arm of the fiber was connected to a light source (DH-2000-BAL; Ocean Optics).
The BAL fluid samples were immediately protected from light and put on ice.
Total and cell differential counts were determined in BAL fluid using morphologic criteria under a light microscope with the evaluation of > 500 cells/slide.
BAL cell types in cytospin preparations were analyzed by light microscopy and BAL supernatant was analyzed using ELISAs, specific to bovine inflammatory cytokines.
Standing in the center of a large concrete void, bathed in fluorescent light, Peters, white-gloved hands balled into fists, held them before him as if bracing against what force you could not have said.
When the same petri plates were incubated under a reduced O2 atmosphere (2% O2, 5% CO2, bal. N2), strain 66205 colonies appeared light-blue, or partially induced.
