The present study was designed to investigate the effect of a modified immunotherapy (IT) with an allergen-pullulan conjugate (CS-560) in patients with SAR to Japanese cedar pollen (Japanese cedar pollinosis) using objective parameters, such as analyzing the alteration in the proportion of effector cells like mast cells, eosinophils and T cells, and the Th2 and Th1 cytokine profile.
Similar to HOC8, the O2 insensitive cell lines, SKOV3 and HeyA8, did not display a significant alteration in the proportion of cells in the G2 phase of the cell cycle when grown under 3% O2 or 21% O2 (Table 1).
One of the other profound changes that accompany tumor proliferation is alteration in the proportion of choline-containing metabolites.
We found no profound alteration in the proportion of myeloid and T cell populations infiltrating tumors in HB-19 treated and related control RET mice.
Analysis of cell cycle kinetics at 0, 24 and 48 h postexposure to ZD1839 (0.1 and 10 μ M) revealed no demonstrable alteration in the proportion of cells in different phases of the cell cycle in relation to control cells.
Therefore, this increase in Nanog protein could be due to either a general increase in the level of Nanog per cell or an alteration in the proportion of cells in the Nanog-negative compartment.
Since the majority of HIV-1-infected individuals in our cohort had undetectable viral loads and we show that both CD56dim CD16+ and CD56bright CD16− NK cells expressed equal levels of FcRγ, alterations in the proportion of these subsets are unlikely to account for the FcRγ depletion observed in our study.
The finding of alterations in the proportion of arteriole-sized vessels is potentially important as these vessels regulate the flow of blood through the capillary beds they supply.

Futhermore, this study suggests that the PEA may represent a useful adjunct to the PRA for monitoring alterations in the proportion of drug-resistant virus even when no change in IC50 is apparent.
To determine if the effects in the Faah−/− mice were related to a correction in the baseline alterations in the proportion of NPCs within the SGZ converting into neurons or astroglia in the GFAP/Gp120//Faah−/− mice, we performed analysis on brain sections double labeled for BrdU and GFAP.
