Due to controlled devitrification and evolution of variable proportions of crystalline and glassy phases, glass-ceramics substantially overcome the lacunae encountered in glasses.
Hamartoma is a painless, mobile mass, composed of variable proportions of glandular, adipose and connective tissue.
Clastic components of Franciscan OPS units are composed of variable proportions of turbidite and mélange with non-native (exotic) blocks, including those of higher metamorphic grade than the matrix.
Most Franciscan OPS comprises MORB (mid-ocean-ridge basalt) progressively overlain by chert and trench-fill clastic sedimentary rocks that are composed of variable proportions of turbidites and siliciclastic and serpentinite-matrix olistostromes (sedimentary mélanges).
This provides a description of Troll's bauplan of the angiosperm plant [32], [33] and the principle of variable proportions (Figure 3D J) [33], [33].
Our interpretations also represent Troll's bauplan of the angiosperms, the principle of variable proportions, morphological misfits, the basic types of stem segmentation, and Goethe's principle of metamorphosis in terms of CIT.
These results were further supported by: i) the presence of increased proportions of Olig1+ PDGFRα+ (≈20% versus 8%; Fig. S3A) and, to a lesser extent, of Sox10+PDGFRα+ cells (≈6% vs 2%; Fig. S3B) in FPN vs EF hNSCs exposed to PDGF-AA+T3; ii) the presence of variable proportions of PDGFRα+ hNSCs expressing nestin (Fig. S3C), but not PSA-NCAM (Fig. S3D) or GFAP (Fig. S3E, F).
We conclude that much of the within-mouse variation observed for heart tissue is a consequence of variable proportions of anatomical substructures, specifically ventricular tissue, within the samples.
A similar finding was reported in Dutch patients (13), and this situation could be related to the presence of variable proportions of maternal antibodies against these different viruses.
However, observations of variable proportions of guanine and cytosine (GC) in different species and in different genomic regions of vertebrates [reviewed in [ 1, 2]] have prompted the analysis of forces that may affect the evolution of complete genomes.
