However, QTL identified under a specific genetic background usually show relatively small effects or even cannot be detected under other genetic backgrounds [ 9], and several studies have been done to integrate the results from multiple independent QTL mapping experiments to unravel genetic factors underlying complex traits [ 9- 11].
The woes of beautiful people have traditionally provoked tears so minute that they cannot be detected even by the naked eye that weeps them.
(It is virtually impossible to measure new H.I.V. infections in poor countries, since symptoms do not show up for years, routine testing is almost nonexistent and the virus cannot be detected even in tested people until weeks after infection).
However, a structural modification or surface functionalization may exist during CF4 plasma treatment [14, 16, 17], even though they cannot be detected by normal optical microscopy.
However, the inherent limitation of kinetic studies using cell populations [1], [3], [8], [9] is that transient activities that are not synchronized from cell to cell cannot be detected even by the most quantitative assays (Fig. 1A) [11], [11].
Very recently, Brandt et al. also reported a similar finding that mitogenicity cannot be detected even in speG- and speG dys -positive speG dys -positivealactiae Streptococcusuisimilis isolates from patients with invasive infections[42].
In contrast, there is also a 50% chance that the two sperms have an identical allele at the same locus, which leads to an identical genotype between endosperm and embryo, and thus HF event cannot be detected even if the HF has occurred (Figure 1).
It is likely that the CNSs have degraded over evolutionary time but the binding functions may be conserved even though they cannot be detected by sequence alignment due to binding site turnover.
However, despite this, we did not find any mutations in the TK domain of EGFR: in addition to confirming previous findings (Cortese et al, 2006; Velcheti et al, 2009), this also indicates that, unlike in the case of lung adenocarcinomas, mutations cannot be detected even when real-time PCR is used to increase sensitivity (Allegrini et al, 2012).
