However, further studies are needed to confirm this hypothesis with assessment of various inflammatory cells, cytokines and chemotactic molecules in BAL fluid.
Consistent with this hypothesis, histological assessment showed that, in contrast to the reference strain which reached the granular and prickle epithelial cell layers, the hyr/hyr1 mutant was confined within the keratin layer (Fig. 9 arrows).
Surprisingly, several studies have failed to support the hypothesis that assessment of pulmonary vein number, location, and branching prior to RFA affects long-term efficacy of RFA [ 44– 44].
In accordance with the latter hypothesis, stereological assessment of neocortical microglial numbers revealed a ~14% increase in the total microglial number in the cortex.
Despite the deceiving simplicity of this hypothesis, its assessment is not trivial and depends on whether the covariances of the models, generally unknown, are homogeneous or not.
These results were compatible with a working hypothesis that assessment of tissue characteristics of carotid plaque as well as its size is useful for screening groups with a high risk of CVE.
Alvarez (1946) tested the single-origin hypothesis through assessment of a number of morphological features (e.g., fin ray number, body proportion measurements) in the Chica, Sabinos and Pachón caves.
Because FS and NFS follow a normal Gaussian distribution under the null hypothesis, the assessment of statistical significance of the association can be done on the basis of the deviation of these statistics from the standard critical values under normal distribution.
There are no a priori restrictions on the form of the evidence for species hypotheses, but assessment of improbability of evidence is important in avoiding an arbitrary, grab-bag, approach.
