Scaffold, as one of the components for bone tissue engineering, requires formulated biomaterials that are both structurally and compositively similar to composition. Among others, chitosan, gelatin chondroitin sulfate known potential candidates scaffold composites can be easily obtained from waste-based resources. This study aims investigate cytotoxicity different composition concentration regi...

Vascular endothelial growth factor (VEGF)-A is an autocrine survival factor for podocytes, which express two VEGF receptors, VEGF-R1 and VEGF-R3. As VEGF-A is not a known ligand for VEGF-R3, the aim of this investigation was to examine whether VEGF-C, a known ligand for VEGF-R3, served a function in podocyte biology and whether this was VEGF-R3 dependent. VEGF-C protein expression was localized...

Antigen capture enzyme-linked immunosorbent assays (ELISAs) for the detection of Stx1 and/or Stx2 in cattle feces were validated in comparison to the Vero cell cytotoxicity neutralization test (as a "gold standard") applied in the course of a monitoring program for Shiga toxin-producing Escherichia coli in German cattle herds as a prescreening test and compared to MK1/MK2 PCR as an alternative ...

background: endodontic sealers usually come in contact with adjacent tissues and their biocompatibility is key in a successful treatment. the purpose of this study was to assess the cytotoxicity of three resin-based sealers, namely ah plus, endorez, and epiphany in set and fresh states on an l929 cell line. materials and methods: in this in vitro experimental study, the materials were mixed acc...

In vitro cell-mediated cytotoxicity (CMC) assays have been carried out in human melanoma system with blood effector lymphocytes on [3H]proline-labeled target cells in a 48-hr microcytotoxicity technique. Three lymphocyte purification procedures (Ficoll:Hypaque gradient, plasma gel sedimentation followed by nylon column incubation, and plasma gel sedimentation followed by separation with nylon p...

BACKGROUND Three-dimensional (3D) spheroids are frequently used in toxicological study because their morphology and function closely resemble those of tissue. As these properties are maintained over a long term, repeated treatment of the spheroids with a test object is possible. Generally, in the repeated treatment test to assess cytotoxicity in the spheroids, ATP assay, colorimetric measuremen...

INTRODUCTION Most denture base acrylic resins have polymethylmethacrylate in their composition. Several authors have discussed the polymerization process involved in converting monomer into polymer because adequate polymerization is a crucial factor in optimizing the physical properties and biocompatibility of denture base acrylic resins. To ensure the safety of these materials, in vitro cytoto...

CONTEXT Thyroid antibody-dependent cytotoxicity has been reported in autoimmune thyroid disease (AITD). Indeed, the role of thyroperoxidase (TPO) autoantibodies (aAbs) in complement-mediated damage by binding to TPO expressed on the surface of human thyroid cells was demonstrated, whereas their activity in antibody-dependent cell cytotoxicity (ADCC) is not well established. OBJECTIVE The aim ...

objective(s):according to the prevalence of neoplastic diseases, there is a deep necessity for discovery of novel anticancer drugs in the field of medicinal chemistry. in the current study, a new series ofphenylthiazole derivatives(compounds 4a-4f) was synthesizedand theiranticancer activity was assessed in vitro. materials and methods:all synthesized derivatives were evaluated towards three hu...

b ackgro un d : the antimicrobial activity of silver nanoparticles has been investigated in medical fields in recent years, but there are few studies regarding its effect on oral microorganisms. the aim of the present study was to evaluate the in vitro antimicrobial and toxicity properties of nanosilver against two dental plaque microorganisms  and human gingival fibroblast (hgf) cell line. me ...
