The species has a number of distinctive microscopic features, including very long cystidia on the stem, visible as bristles.
At this resolution, many microscopic features, including cell layers and small white matter tracts, can be identified (Fig. 1 A, B, arrows).
Despite radiological and neuropathological features deemed as classic are acknowledged, PA may present a bewildering variety of microscopic features, including a wide range of tissue patterns, most of which may be found within the same lesion.
Characteristic microscopic features include asci that are amyloid (so their tips stain blue at the tip with iodine), and smooth, blunt-ended, ellipsoid spores with large oil droplets.
Consistent microscopic features include prominent pathology at the brain surface overlying the polymicrogyric cortex.
The microscopic features included the chondroblast, osteoclast like giant cells, mitotic rate of less than 4 per high power field, islands of primitive chondroid and chicken wire calcification.
Particular attention is paid to the microscopic transport features, including carrier mean free paths or number of scattering events along the channel for investigating the optimization of the device topology and the strategic concepts related to the noise performance of this new architecture.
Microscopic distinguishing features include the smooth, spindle-shaped cheilocystidia and pleurocystidia (cystidia on the gill edge and face, respectively) and the diverticulate elements in the outer layer of the cap and the stem.
These criteria include the age of the patient, extent of disease spread, microscopic appearance, and genetic features including DNA ploidy and N-myc oncogene amplification (N-myc regulates microRNAs ), into low, intermediate, and high risk disease.
Historically, Alexandrium species were described based on microscopic observations of morphological features including plate patterns, cell size and shape, and secondary characteristics such as chain formation.
OSA in both species shares many features including the presence of microscopic metastatic disease at diagnosis, the development of chemotherapy resistant metastases, and dysregulation of several key cellular proteins including Met, ezrin and STAT3 [ 2- 6].
