In the present study, a nanocrystalline Ni-Fe matrix with reinforced TiO2 nanoparticles as functional nanocomposite material was fabricated by pulsed current electroforming in UV-LIGA (lithography, electroplating, and molding). The influences of on deposition were also investigated using scanning electron microscopy, transmission vitro cytotoxicity assay. It found that 5 wt.% showed smooth surf...

quercetin, a ubiquitous flavonol, represents a promising leading drug for development of new chemotherapeutic agents. however, its limited cytotoxicity to cancer cells hampers its clinical use. in order to obtain novel quercetin derivatives with superior cytotoxicity, seven alkylated quercetin derivatives were synthesized. solubility of these derivatives was determined by turbidimetry. cytotoxi...

Introduction: Bifunctional radiosensitizer agents in which nitroaromatic moieties are attached through a linker to antineoplastic moieties have demonstrated higher cytotoxicity and radiosensitizer effects than the corresponding counterparts. This study was conducted to investigate the cytotoxicity and radiosensitizer activities of 2, 4-dinitrobenzene as a radiosensitizer moiety...

recent evidences suggest that multiple myeloma phenotypes (mmps) are involved in the infiltration of multiple myeloma-affected marrow foci. in this study, the effects of arsenic trioxide on the invasive and angiogenic phenotypes of multiple myeloma (mm) cell line were assessed on a dose-response and time-course basis. multiple myeloma cell line, karpas 707, was treated with step-wise elevated c...

The aim of this study was to compare four in vitro cytotoxicity assays and determine their ability to detect early cytotoxic events. Two hepatoma cell lines, namely HTC and HepG2 cells, were exposed to cadmium chloride (0-300 microM) for 3, 5 and 8 h. Following exposure to the toxic metal cytotoxicity was determined with the lactate dehydrogenase leakage assay (LDH), a protein assay, the neutra...

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...

In vitro studies evaluating the cytotoxic potential of substances released from dental adhesives are lacking. The purpose this study was to compare cytotoxicity extracts Scotchbond Universal and Optibond Solo Plus, an adhesive in experimental phase: T1. 3T3 mouse fibroblast cells MG-63 osteoblast-like human osteosarcoma were exposed for 24 h serial extract dilutions. Cytotoxicity determined usi...
