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).
