Thus the morphological grading of immature ovine oocytes may be an appropriate selection criterion regarding their developmental ability.
The morphological grades of transferred euploid blastocysts were compared between the time lapse system (Group A) and the conventional incubator (Group B) (Table 5).
In all patients from the seven hospitals in central Norway regional health authority morphological grading of stenosis was performed with a preoperative magnetic resonance imaging (n=162).
The clinicians who review the preoperative MRI and perform the morphological grading of the severity of spinal stenosis will be blinded with regard to treatment allocation (laminectomy or microdecompression).
For patients with available preoperative MRI we review the images and perform a morphological grading of the severity of spinal stenosis as described by Schizas et al. 14 This morphological grading from A to D is based on the cerebrospinal fluid/rootlet ratio as seen on axial T2-weighted MRI.
Briefly, morphological grade was performed including the number of blastomeres (2 8), the amount of the fragmentation (1 4, with the fourth scale representing no fragmentation), and the regularity of the blastomeres (1-2, withethe second scale representing the regular blastomeres).
When the morphological grade was used as such a marker, long-term follow-up studies demonstrated that almost a third of HGNs remained unchanged despite their high-grade histology [ 12].
In the case of Persea, the results could be interpreted in the context of the 'fading borders' model, which correlates the presence of morphological grades between floral organs with similar gradients of floral organ identity gene expression [24].
Administration of LH 6 h prior to OPU increased (P < 0.05) the oocytes of higher morphological grades, and in the absence of a CIDR, improved (P < 0.05) blastocyst development rate.
Aquilegia flowers do not have the same kind of morphological grades observed in magnoliid dicots but the presence of petaloid sepals and the stamen-derived staminodia may provide analogous patterns.
