Several studies report that the resistant virus spontaneously reverts to a wide-type genotype by one year [ 14, 26], meaning that the resistance would not have altered effectiveness of prevention in further pregnancies.
In general, the age-induced altered natural biological and immunological activities would lead to altered effectiveness of immune surveillance, the balance between tumoricidal (Yin) vs. tumorigenic (Yang) properties of immune system, weakening the body's ability to respond to new stimuli that potentially threaten the body's survival.
SERCA is highly sensitive to oxidative damage and, in ApoE−/− mice with demonstrable atherosclerotic plaques, we found nitrotyrosine staining around the plaque correlated with a progressive reduction in SERCA protein expression and altered effectiveness of TG in inhibiting ONOO-induced relaxation.
These essential elements cannot be changed without fundamentally changing the intervention, whereas other characteristics may be modified without altering effectiveness [ 26].

Increased population pressure and human activities have significantly altered the effectiveness of functions of ecosystems ("ecosystem services") at the local and regional scale.
Change in HRQL, as measured by the RSDI, was significantly associated with change in days of restricted activity, altered job effectiveness, and incremental medication costs, but was not associated with differing frequency of physician visits relative to baseline (Table 4).
No treatments altered glucose effectiveness, a measure of insulin-independent glucose disposal (0.017 ± 0.006, 0.017 ± 0.008, 0.017 ± 0.009, and 0.015 ± 0.007 min−1 for placebo, tadalafil, ramipril, and ramipril plus tadalafil, respectively).
In addition, we evaluated whether HIV exposure altered vaccine effectiveness (VE), because the increasing availability of interventions for prevention of mother-to-child transmission (PMTCT) of HIV in high HIV-prevalence settings has led to increasing numbers of HIV-exposed but -uninfected children; however, there are no published data on PCV efficacy or effectiveness in this group [ 15, 16].
