abstract: background and aim: resin cements are used widely in restorative dentistry regardless of their biocompatibility. the aim of this study was to compare the cytotoxicity of two categories of dental cements consisting of three chemically set cements (fuji i, fuji plus and harvard) and two dual curing cements (biscem and duo-link) by use of mtt assay. materials and methods: in this experim...

a series of fluoroquinolone derivatives holding triazolidindione moieties have been synthesized and proved to be cytotoxic agents in vitro particularly against cancer cell lines (sknmc, mcf7, a2780-cp, sw48, a549, kb, ht-29, hepg 2 ). the cytotoxic activity was assessed using mtt colorimetric assay. our compounds had less cytotoxicity than doxorubicin in all studied cell lines.

This study was planned to explore the capability of nanoemulsions (NEs) consisting of CapryolTM 90 and oleic acid for the delivery of rapamycin (RAP). Permeability and cytotoxicity of RAP-loaded NEs were also inspected. Pseudo-ternary phase diagrams were created with oleic acid and CapryolTM 90 (as oil phase) and four surfactants and co-surfactants at various weight ratios (Rsm). Selected NEs f...

BACKGROUND Carbon nanodots (CD), a new class of carbon nanomaterials with sizes below 10 nm, have recently attracted wide attention due to their superiority in water solubility, chemical inertness, and resistance to photobleaching. As a result, CD has found important and wide applications in energy, catalysis, biological labeling, bioimaging and drug delivery. On the other hand, due to the lack...

Recently, regular and white mineral trioxide aggregate (MTA) are being used in Dentistry as retrofilling materials. Genotoxicity and cytotoxicity tests form an important part of cancer research and risk assessment of potential carcinogens. Thus, the goal of this study was to examine the genotoxicity and cytotoxicity of regular and white MTA in vitro by the single cell gel (comet) assay and tryp...
