In vivo biological behavior of calcium phosphate cements with different Ca/P ratio
(2009-02-02)
Bioceramics with different Ca/P ratio were prepared from a mechanical mixture of NaPO3, CaCO3, Ca(OH)2 and phosphate buffer solution and implanted in rats subcutaneous tissues. The cements were characterized by Thermo ...
Detection of estrogen receptor in formalin-fixed and paraffin-embedded breast carcinoma: correlation with histological patterns.
(1992-07-01)
The authors studied the expression of estrogen receptor (ER) in tissues of breast carcinomas which were previously fixed in formalin and paraffin-embedded. The ER expression was correlated with several histological findings, ...
Detection of bovine Herpesvirus type 5 in formalin-fixed, paraffin-embedded bovine brain by PCR: a useful adjunct to conventional tissue-based diagnostic test of bovine encephalitis
(Elsevier B.V., 2007-12-01)
The aim of this study was to evaluate the application of PCR technique for the detection of BoHV-5 in routinely formalin-fixed, paraffin-embedded brain tissues in 20 naturally infected calves affected by fatal meningoencephalitis. ...
Sentinel lymph node biopsy in rats. Comparison between paraffin and frozen section analysis
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2014-01-01)
PURPOSE:To simulate a lymph node metastasis in an animal model using activated carbon, assess their identification in frozen section analysis and compare with histopathological examination in paraffin.METHODS:Thirty two ...
Copper determination in ethanol fuel by differential pulse anodic stripping voltammetry at a solid paraffin-based carbon paste electrode modified with 2-aminothiazole organofunctionalized silica
(Elsevier B.V., 2007-02-15)
Solid paraffin-based carbon paste electrodes modified with 2-aminothiazole organofunctionalized silica have been applied to the anodic stripping determination of copper ions in ethanol fuel samples without any sample ...
Proliferating cell nuclear antigen (PCNA) in non-Hodgkin's lymphomas: Correlation with working formulation and Kiel classification in formalin-fixed paraffin-embedded material
(1996-03-13)
PCNA is a 36-KD proliferating cell nuclear antigen associated with the cell cycle. The immunocytochemical detection of PCNA represents a useful tool for the study of tumor proliferation activity. This study documents the ...
A solid paraffin-based carbon paste electrode modified with 2-aminothiazole organofunctionalized silica for differential pulse adsorptive stripping analysis of nickel in ethanol fuel
(Elsevier B.V., 2007-02-19)
A solid paraffin-based carbon paste electrode modified with 2-aminothiazole organofunctionalized silica (SiAt-SPCPE) was applied to Ni2+ determination in commercial ethanol fuel samples. The proposed method comprised four ...
DNA extraction and molecular analysis of non-tumoral liver, spleen, and brain from autopsy samples: the effect of formalin fixation and paraffin embedding
(Elsevier B.V., 2012-01-01)
The use of molecular biology in combination with morphological analysis is increasing because of the treatments by target therapies. However, to improve the methods for obtaining DNA for molecular analyses from formalin-fixed, ...
A rapid technique for analysis of formalin-fixed, paraffin-embedded tissues by fluorescent in situ hybridization with alpha-satellite probes
(Sociedade Brasileira de Genética, 1998-12-01)
Descrevemos aqui um procedimento rápido para obtenção de núcleos interfásicos a partir de amostras arquivadas que podem ser utilizados para análise citogenética através da técnica de FISH. Este procedimento difere de outros ...
Avaliação de dois métodos de extração de DNA de material parafinado para amplificação em PCR
(Sociedade Brasileira de Patologia ClínicaSociedade Brasileira de PatologiaSociedade Brasileira de Citopatologia, 2007-04-01)
INTRODUÇÃO: Diversos métodos para extração de DNA a partir de tecidos biológicos inclusos em parafina encontram-se descritos na literatura, sendo o sucesso desse procedimento de grande importância para a realização de ...
