When DNA damage occurred in G2 cells (~ 10% of the total cell population), a stringent G2 arrest was observed 2 hr post-IR, as indicated by ≥ 94% reduction in mitotic cells.
This requires absolute population numbers Nnstat(r) ≫ 1/ μ for all relevant r, a stringent condition on the total population size N.
Thus, embryo grafting provides a stringent assay for testing how distinct cell populations respond to region-specific differentiation-inducing signals.
Tukey's post hoc test is a stringent test identifying pairwise differences within the populations considered for ANOVA.
Thus, to obtain pure WBC populations, we developed and implemented a stringent sorting protocol that excludes erythroid-specific surface markers.
We used a stringent cutoff for defining seropositivity, which probably underestimated the seroprevalence in our population.
Despite the use of a stringent threshold (P ≤ 0·001) for detecting QTLs in the two populations, about one-third are common (Table 3).
As a stringent test of the ability of SWIFT to identify rare, but biologically significant populations, we stimulated human PBMC with influenza peptide antigens to induce rare (<0.01%) cytokine-secreting populations absent in negative controls 22, 36.
The small political parties that represent the Arab population in Israel — 1.7 million out of more than eight million — reacted to a stringent new election law designed by the right wing to limit their presence in the Knesset, the national legislature.
Selecting the jointly top-ranked genes imposes a stringent cutoff for the identified genes, and reduces potential bias introduced due to local ancestry or population structure.
The Civil Human Rights Front organized a march last July 1 that drew 500,000 people, nearly one-tenth of the population of this autonomous Chinese territory, and forced the local government to withdraw a stringent internal security law.
