Sentence examples for variation and fixation from inspiring English sources

We employed a more rigorous test to distinguish between mutational variation and fixation biases for the shift in background substitutional patterns in D. saltans/willistoni.

Anterior and posterior parallel opposed fields encompassed the initial planned target volume (PTV), consisting of CTV1 3, with the superior and inferior field margins extended to 1.5 cm and lateral field margins extended to 1.5 cm to allow for respiratory variation and fixation error.

Predicting the genetics consequences of small population size has been one of the major tasks of conservation biology, because a reduction can result in inbreeding, loss of genetic variation and fixation of deleterious alleles, and thereby decrease the evolutionary potential and increase the probability of population extinction (Maudet et al. 2002).

Genetic variation was partitioned and fixation indices were estimated using an analysis of molecular variance (AMOVA), as implemented in ARLEQUIN.

Therefore, the variation in delay in sampling and freezing of tissues initially is small and the delay and variation in fixation is also minimal and all blocks are small and fixed for a standard length of time.

Reasons for this low percentage of positivity include tumor heterogeneity, sample aging and effects of and variation in fixation methods.

Differences in post-mortem time before tissue fixation and variations in fixation and immunostaining protocols are other confounders.

This article reviews the current state of knowledge about the glenoid in total shoulder arthroplasty, summarizing the anatomic parameters of the intact glenoid, variations in component design and fixation, the mechanisms of glenoid loosening, the outcomes of revision surgery in the treatment of glenoid component failure, and alternative treatments for younger patients.

However, we know that the impaction of variation in the fixation time and fixation methods on counting of the mitosis is neither significant nor explain the proliferative difference between varied population [ 32, 33].

This pattern is achieved through two independent mechanisms known as homogenization (i.e. the spreading of a variation to the whole repeat array) and fixation (i.e. the fixation of the variant within a taxonomic unit).

Note that the presence of H&E staining does not affect the reported F/B (15), but that the effects of possible variation in time between excision from patient and fixation, as well as the effects of possible variation in time of fixation, are not known and those times are not recorded for the data sets studied here.
