Children whose mothers took no dietary supplements in the specified exposure interval
were the reference group (n = 9052 [24%], with severe language delay in 81 children [0.
The Resin B coating continued to deteriorate during the second three-month exposure interval
To be included in the analysis, an exposure interval
must have been initiated during the observation period.
aureus Exposure Interval
Average Control Titer Average Recovered (CFU/mL) (CFU/mL) 30 Seconds 7.
0X Exposure Interval
1 sec (flash off) Booting up 1.
In treatments with Bti PFF, entire monolayers detached within a 2-hr exposure interval
Giemsa stain of digestive tubule tissue from oysters in the anoxic treatment group from the 24-h, 48-h, and 60-h anoxia exposure intervals
showed bacterial infiltration of digestive tubule hunens and the surrounding Leydig tissue (Fig.
Original antigenic sin seems to be most pronounced when sequential viruses are of intermediate antigenic relatedness; when they are antigenically complex; and when sequential exposure intervals
are long, consistent with ongoing selection and expansion of lymphocyte clones that have increasing antibody avidity at key cross-reactive epitopes (7-10) and possibly with epitope competition between naive and antigen-specific B cells (8).
Further analysis of QTd and HR changes between prehypoxic, hypoxic, and posthypoxic intervals showed a significant change in HR between all exposure intervals
and in QTd between the hypoxic and prehypoxic interval.
Considering that inadequate statistical tests were conducted due to the small sample size and multiple exposure intervals
, our results may only represent the substantial differences with a large variation in high standard errors and therefore reveal no solid and conclusive evidence in the possible alterations in electrophysiological responses due to PEMF.
We investigated the effect of different ozone concentrations in the air and different exposure intervals
on the viability of freshly prepared conidia of common environmental fungi.
In order to estimate the incidence of MMD resulting from IQ reduction attributable to lead exposure, it was first necessary to estimate the proportion of the child population in IQ categories corresponding to lead exposure intervals
based on the assumption that intelligence in human populations approximates a normal distribution (21) (Table III).
