Intra-operative frozen section plays an important role in the management of surgical patients and yet it must be used prudently to avoid the indiscriminate usage of this important technique. As it is subjected to many limitations in comparison to the paraffin embedded tissue sections, this review aims to highlight the important concepts and principle of intra-operative frozen section consultati...
Telepathology (TP) uses telecommunication linkages to electronically capture, store, retrieve, and transmit images to distant sites. We assessed the feasibility of a dynamic real-time TP system for light microscopic (LM) diagnosis of anatomic pathology specimens, including frozen sections. Six pathologists, in 2 separate periods, read a set of 160 retrospectively retrieved slides (80 of which w...
The elasticity of biological tissues is one the physical characteristics and has attracted attention as a clinical diagnostic parameter. can be determined on microscopic scale with speed sound (SoS) measurements using acoustic microscopy. In SoS measurements, thin-sliced section attached to glass slide in same manner light specimen. There are two main methods for preparing thin sections: paraff...
BACKGROUND Self-made tissue punches can be effectively used to punch holes in blank recipient paraffin blocks and extract tissue cores from the donor paraffin blocks for the low-cost construction of tissue microarrays (TMAs). However, variable degrees of section distortion and loss of the tissue cores can occurs during cutting of the TMAs, posing technical problems for in-house manual construct...
There is a large amount of tissue stored in brain collections and brain banks, but little is known about whether formalin-fixed tissues and paraffin blocks stored for years in brain banks are suitable for the retrospective genetic studies. The study was carried out in order to: (i) compare DNA preservation in frozen, formalin-fixed and paraffin-embedded tissues stored for different periods; (ii...
the present study performed to examine canola meal on morphology of thyroid gland in broiler chicks. in this experiment 300 l-day-old unsexed ross broiler chicks assigned into 5 groups. the chicks were fed by five level of canola meal (0, 5, 10, 15 and 20%). after 42 days feeding four chicks from each pen killed and their thyroid glands removed and immediately were immersed in formaldehyde, bef...
