Vimentin is an intermediate filament protein normally expressed in cells of mesenchymal origin, e.g. myofibroblasts, chondrocytes, macrophages, and endothelial cells. The expression of vimentin, which has been thought of as the main mesenchymal marker, is also detected in tumour tissue. In tumours of the gastrointestinal tract vimentin expression is usually(More)
The aim of the study was to assess the expression and subcellular localization of visfatin in HCT-116 colorectal carcinoma cells after cytokinesis failure using Cytochalasin B (CytB) and the mechanism of apoptosis of cells after CytB. We observed translocation of visfatin's antigen in cytB treated colorectal carcinoma HCT-116 cells from cytosol to nucleus.(More)
Visfatin has recently been established as a novel adipokine that is predominantly expressed in visceral fat. Recombinant visfatin has immunomodulating properties, which can activate human leukocytes in vitro to induce cytokine production (IL-1β, TNF-α, and IL-6). Only few studies have investigated the effect of visfatin on prostate, breast, ovarian cancer(More)
From the histological point of view, fascia lata is a dense connective tissue. Although extracellular matrix is certainly the most predominant fascia's feature, there are also several cell populations encountered within this structure. The aim of this study was to describe the existence and characteristics of fascia lata cell populations viewed through a(More)
Over the years Transmission Electron Microscopy (TEM) has evolved into a powerful technique for the structural analysis of cells and tissues at various levels of resolution. However, optimal sample preservation is required to achieve results consistent with reality. During the last few decades, conventional preparation methods have provided most of the(More)
In this paper a method is introduced which enables automatic detection of immunogold markers in transmission electron micrographs. Immunogold markers are used in electron microscopy to determine sub-cellular location of biological relevant macromolecules, such as proteins, lipids, carbohydrates, and nucleic acids. The proposed method combines image(More)
Fascia lata is an important element of the fascial system, which forms the continuum of connective tissue throughout the body. This deep fascia envelops the entire thigh and hip area and its main function is to transmit mechanical forces generated by the musculoskeletal system of the lower extremities. Fascia lata is also known as a useful and easily(More)
AIMS Several lines of evidence point to hypercoagulability as an important factor for heart failure (HF) pathogenesis. METHODS We hypothesised that endothelial tissue factor (TF) expression reflects altered tissue haemostasis which is related to the severity of HF. Accordingly, we investigated TF expression in the biopsies of 60 patients with HF and 22(More)
Currently, the exact role of telocytes within fascial structures is unknown. The morphology, distribution and behaviour of fascial telocytes as well as the mutual relationship between telocytes and other cellular fascia constituents should be definitely a subject of further studies. It will contribute to better understanding of the role of the fascial(More)
The influence of lead acetate on the ultrastructure of peripheral neutrophils was investigated in adult male rats. It was found that a single intraperitoneal administration of lead at dose 150 mg Pb/kg b.w. led to ultrastructural changes in the neutrophils at 3 and 6 h post injection. At the time of testing the exposed population had a mean (+/- SD) blood(More)
