Autophagy assures cellular homeostasis, and gains increasing importance in cancer, where it impacts on carcinogenesis, propagation of the malignant phenotype and development of resistance. To date, its tissue-based analysis by immunohistochemistry remains poorly standardized. Here we show the feasibility of specifically and reliably assessing the autophagy markers LC3B and p62 (SQSTM1) in forma...
Within SPIDIA, an EC FP7 project aimed to improve pre analytic procedures, the PAXgene Tissue System (PAXgene), was designed to improve tissue quality for parallel molecular and morphological analysis. Within the SPIDIA project promising results were found in both genomic and proteomic experiments with PAXgene-fixed and paraffin embedded tissue derived biomolecules. But, for this technology to ...
Introduction: Nowadays the consumption of meat and animal carcasses in most countries is increasing. Regarding to economic values of meat, usage of unauthorized tissues in minced meat by jobbers is probable. Therefore; the present study was performed in order to detect unauthorized tissues in minced meat. Methods: In this study, a total of 20 samples of trade frozen minced meat was purchas...
This study aimed to extract the paraffin component from paraffin-embedded oral cancer tissue spectra using three multivariate analysis (MVA) methods; Independent Component Analysis (ICA), Partial Least Squares (PLS) and Independent Component - Partial Least Square (IC-PLS). The estimated paraffin components were used for removing the contribution of paraffin from the tissue spectra. These three...
Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world´s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study was to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of ...
AIMS To isolate RNA and DNA simultaneously from formalin fixed paraffin wax embedded tissue to assess the clonality of enteropathy associated T cell lymphomas and to analyse it in detail by a non-radioactive method of T cell receptor complementarity determining region 3 (CDR3) spectratyping. METHODS DNA and RNA were isolated simultaneously from formalin fixed paraffin wax embedded tissue bloc...
application of morphological method for detection of unauthorized tissues in processed meat products
background: nowadays, there is an increase of meat and animal carcass consumption worldwide. due to the economic value of meat, the likelihood of using unauthorized tissue is possible in meat products. based on these observations, the aim of the present study was to apply morphological method for detection of unauthorized tissues in processed meat products. methods: in this study, a total of 2...
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...
