Media for the batch and fed stages were based on the cell specific amino acid requirements, which allowed a more accurate determination of the initiation of the fed stage and the frequency of nutrient addition from then on.
Among the many variables that can be calculated for that purpose are the time (percentage) spent in each sleep stage, and the frequency of stage shifts.
A significant association was established between HIV stage and brushing frequency (p = 0.0190) as well as the use of interdental aids (p = 0.0170).
In contrast, only 17.9% (34/190) of the non- TCF3-rearranged cases was arrested at the IGH stage and the frequency of cases with light chain rearrangements was significantly increased to 18.4% (35/190) for samples arrested at IGK, 38.4% (73/190) for IGK-Kde and 24.7% (47/190) for IGL (P<0.001).
We detected expressions of miRNAs in multiple developmental stages, and the frequency of any single miRNA appearing in sequenced libraries varied from one to seven (Table 3).
It is known that stromules form at certain developmental stages, and the frequency of these protrusions is elevated when plants are exposed to a variety of stresses (biotic as well as abiotic) (reviewed in [ 14]).
The majority of KIMAP mice did not progress to NE CaP, which was observed only at a very late stage and a low frequency.
The objectives were to test whether (1) melatonin blocks inhibition of embryonic development caused by heat shock at the zygote stage, and (2) the frequency of a thermoprotective allele for HSPA1L is increased in blastocysts formed from heat-shocked zygotes as compared with blastocysts from control zygotes.
Although the reasons why HCC with a higher baseline DCP level is related to poor prognosis remain uncertain, it may in part be due to the fact that the higher baseline DCP level is significantly associated with the presence of vascular invasion, intra-hepatic metastasis, tumor size, Tumor-Node-Metastasis (TNM) stage, and a high frequency of tumor recurrence [ 42].
Variation is kept due to various mechanisms such as favoring distinct phenotypes under different environmental situations or under different developmental stages, and negative frequency-dependent selection, operating when the success of a phenotype depends on its frequency in the population (Brockmann 2001).
