We also employed time-dependent fluorescence lifetime microscopy (FLIM) with time-correlated single photon counting (TCSPC) to detect the lifetime differences of Di-4 that are sensitive to local cholesterol content.
Similar to results from MβCD-treated HbAA parasitized erythrocytes, MβCD treatment collapsed the lifetime differences between the host cell membrane, PVM and PM of parasitized HbAS and HbSS cells (Fig. 5D,E).
These lifetimes were on average 14% lower than those from the pEM but 10% higher than those from PVM (Fig. 2C, left, P pEM-MC/TVN<0.001, PMC/TVN-PVM = 0.005, nMC/TVN = 56), and the lifetime differences ΔpEM-MC/TVN (229±142 ps, n = 56) and ΔMC/TVN-PVM (176±160 ps, n = 56) (mean ± s.d).
It should be noticed that the industrially implemented Deacon reaction (HCl oxidation) runs slightly below 600 K. Thus, the lifetime differences between the two models is too large to rely on predictions of M-I when it is used in the simulations of complex reaction networks on RuO2.
For sample 13, a low AF intensity in the lesional ROI reduced the accuracy of the measured lifetime difference.
The average lifetime difference in personal income between the dropouts and the children who finish school is over a million dollars.
Differences between lifetime values in the pEM and the PVM (≈290 ps) were similar to the differences between lifetime values in the PVM and PM (≈230 ps); these two differences, added together, accounted for the large Di-4 lifetime difference between the erythrocyte and PM (≈500 ps) (P<0.00001) (Fig. 1G).
Their model takes into account the relative lifetime differences between arrays and between the scalars covered by each array.
The effects are not small: one study showed that an American worker who was among the bottom one-seventh in looks, as assessed by randomly chosen observers, earned 10 to 15 percent less per year than a similar worker whose looks were assessed in the top one-third — a lifetime difference, in a typical case, of about $230,000.
