Serial sections were cut at 6 m from each tissue block.

Results Totally 17 patients specimen were retrieved from the archived tissue blocks.

Medical records are often destroyed after a period of time, tissue blocks are thrown away."

However, applications to larger tissue blocks of entire nervous systems have traditionally had difficulty with projections that span longer distances.

After dehydration in graded alcohol, the tissue blocks were embedded in Epon.

Three-micron thick serial sections of paraffin-embedded tissue blocks were numbered consecutively from 1 to 3.

The histological sections of each lesion were reviewed to select tissue blocks containing representative and adequate volumes of tumour.

Battifora H: The multitumor (sausage) tissue block: novel method for immunohistochemical antibody testing.

For automated use with large, tiled tissue blocks, this is faster and more accurate then using an experimentally determined PSF.

Battifora H, Mehta P: The checkerboard tissue block.

A cortical module is defined as either synonymous with a hypercolumn (Mountcastle) or as a tissue block of multiple overlapping hypercolumns.

Free (ionic) calcium forms precipitates with alizarin, and tissue block containing calcium stain red immediately when immersed in alizarin.

The second product is a set of tissue blocks, typically postage stamp-sized portions of tissue sealed in plastic cassettes, which will be processed into slides for microscopic examination.

Tissue blocks were dissected at post-mortem from the hippocampus (at the level of the lateral geniculate body) and the middle temporal gyrus (Brodman's area 21) of both the AD and control cases.

Multi-tissue blocks were first introduced by H. Battifora in 1986 with his so-called "multitumor (sausage) tissue block" and modified in 1990 with its improvement, "the checkerboard tissue block" .

Small tissue blocks of Peyer's patches and the surrounding mucosa at some distance were excised as soon as possible (less than two hours) after collection, and were fixed in cold ethanol (96%) and then embedded in low melting paraffin wax.

We also found that, although samples from the same section gave consistently positive or negative amplification, serial sections from the same tissue block sometimes gave discordant results, presumably due to non-uniform distribution of mycobacteria within the tissue block.
