Microscopic findings in key tissues are often critical to determine the cause of death in medical autopsies. The overall quality of histologic sections depends on numerous pre-analytic factors, among which are tissue section size and thickness. We designed a prospective quality improvement study to deter...
SUMMARY: Fixation is a crucial step in processing of tissue specimen for preservation of cellular architecture and composition of cells. Alcohol-based fixatives are considered some of the most promising alternatives to formalin. We evaluated the performance of alcohol-based fixatives (EthMeth and methaca...
Fixation is one of the processes in preparing histology and pathology. The common material for fixation is buffered formalin including paraformaldehyde. However, the effect of the damaged cells, which is fixed for a long time, causes the research for other fixation materials to become necessary. In addit...
Introducción: el Ministerio de Educación Nacional (MEN) de Colombia reconoció 420 instituciones de educación superior (IES), de las cuales 243 (57.8%) ofrecen programas técnicos o tecnológicos. El procesamiento de tejidos debe tener fundamento teórico y entrenamiento práctico para la preparación...
Regeneration is defined as tissue renewal and functional restoration process of the damaged parts of the body after an injury. Ambystoma mexicanum, commonly named the Axolotl, is one of the unique vertebrates, which has a remarkable ability to regenerate their extremities following the amputation. Althou...
Abstract Most Departments of Pathology around the world have a considerable archive of formalin-fixed paraffin-embedded (FFPE) tissue suitable for molecular assessment. This article points out the potential DNA damage that may occur if basic steps are not followed during processing and storage of these s...
Introdução: A fixação do enxerto cutâneo é essencial para
sua integração no leito receptor. A literatura apresenta várias
técnicas de fixação, porém, o uso da fita de microporosa é
pouco relatado. O objetivo é demonstrar e divulgar o uso da fita
microporosa na fixação do enxerto cutâneo...
BACKGROUND: At present, demanding workplaces in our society cause patients to search for less invasive procedures with diminished morbidity and more rapid healing to meet their cosmetic requirements. A combination of several new noninvasive procedures allows significant facial changes, achieving a youthf...

Glutaraldehyde is the fixative most commonly used in electron microscope studies of biological tissues, however it is often necessary to use samples which were not fixed in this fixative, even with the usual uncertainty of the results that may be obtained. The fixation is the more delicate step of the sa...
Introdução: Para o adequado estudo anatomopatológico dos tecidos obtidos dos pacientes é crucial a boa técnica para a melhor evidenciação das células pesquisadas. É imprescindível que não só a técnica ideal de coloração/marcação seja utilizada, mas também a correta técnica de fixação...
