Fodder yeast (Kluyveromyces fragilis) cells were magnetically modified by a contact with the water-based magnetic fluid in order to prepare a new type of magnetically responsive biocomposite material. This procedure enabled a simple separation of modified cells by means of commercially available magnetic separators or strong permanent magnets. It allows using the prepared material as a new inex...
The normal human epidermal growth factor receptor (EGF-R) (HERc), a chimeric EGF-R/v-erbB (HERerbB) receptor, and the ligand-independent oncogenic EGF-R variant (v-erbB) were used to correct the mast cell defects in W/Wv bone marrow (BM) cells. In culture, all three receptor molecules transduced functional mitogenic signals in infected interleukin-3 (IL-3)-dependent bone marrow-derived mast cel...
The staining properties of tissue mast cells are influenced by the method of fixation. Differences in fixation and staining techniques may explain the contradictory results in the published reports on the number of human mucosal mast cells (MMC) in the gastrointestinal mucosa in health and disease. We have examined the influence of fixatives on the staining properties of human MMC in operative ...
OBJECTIVE Articular cartilage is a complex tissue comprising phenotypically distinct zones. Research has identified the presence of a progenitor cell population in the surface zone of immature articular cartilage. The aim of the present study was to determine the in vivo plasticity of articular cartilage progenitor. DESIGN Chondropogenitor cells were isolated from bovine metacarpalphalangeal ...
Here we present the development of a visual evaluation system for routine assessment of in vitro-engineered cartilaginous tissue. Neocartilage was produced by culturing human articular chondrocytes in pellet culture systems or in a scaffold-free bioreactor system. All engineered tissues were embedded in paraffin and were sectioned and stained with Safranin O-fast green. The evaluation of each s...
PURPOSE The purpose of this study was to study the protective effect and influence of sodium hyaluronate (Na-HA) on mRNA expression of peroxisome proliferators-activated receptor gamma (PPAR-gamma) in cartilage of rabbit osteoarthritis (OA) model. MATERIALS AND METHODS Forty eight white rabbits were randomly divided into A, B, and C groups. Group A was normal control group, B and C groups und...
In this paper, a facile and eco-friendly method for the preparation of Ni nanoparticles (Ni NPs) has been described based on the bioreduction of aqueous Ni(II) precursors with Phlomis cancellata Bunge extract. UV-visible spectrum of the aqueous medium containing Ni nanoparticles showed a peak of 390 nm. Since the experimental conditions of this procedure play vital roles in the synthesis...
Antibiotic resistance in C. difficile by efflux has been previously suggested. The genome of C. difficile 630 was screened for sequences encoding putative proteins homologous to NorA from Staphylococcus aureus. Four ORFs homologous to efflux genes were cloned into the pAT79 shuttle vector under the control of transcription and translation signals of Gram-positive bacteria and expressed in Enter...
