Objective- The purpose of present study was to investigate the viability of equine fibroblast-like synoviocytes (FLSs) treated with doxycycline. Design- Experimental study. Sample population- FLSs from metacarpophalangeal joints of six skeletally mature horses. Methods- FLSs were established from synovial fluids of healthy joints. The cells were treated with different concentr...

We present a large comparative series of trypan blue use in cataract surgery. This series of trypan blue used in all eyes regardless of cataract severity may be unique. We found an apparent increased rate of cystoid macular oedema (CMO) associated with trypan blue use. Melles et al’s report on the use of trypan blue in cataract extraction in 1999 combined with Apple et al’s series on dye enhanc...

It has been reported that trypan blue treatment decreases the nonspecific resistance of mice to transplanted tumors and inhibits the in vitro cytotoxic activity of activated macrophages. We wished to determine whether this effect of trypan blue could be due to a selective inhibition of certain macrophage functions or whether it reflected a broader form of immunosuppression. We therefore tested ...

AIM To evaluate the effects of trypan blue on cell viability and gene expression in human retinal pigment epithelial (RPE) cells. METHODS Three concentrations (0.06 mg/ml, 0.6 mg/ml, and 4 mg/ml) of trypan blue were applied to human ARPE19 cells for 1 minute. Cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. RPE cells were sampled ...

Background and Purpose: The objective of this study was to investigate the therapeutic effect of Folic Acid-Conjugated polyglycerol coated iron oxide nanoparticles on the radiosensitivity of HeLa cells when irradiated with 6 MeV electron beams. Materials and Methods: Different concentrations of iron oxide nanoparticles (PG-SPIONs and FA-PG-SPIONs (25, 50, 100, 200 µg ml-1)) were synthesized by...

introduction: the tumor suppressor p53 protein can induce apoptosis in some cellular contexts. among the apoptosis-inducing genes, p53 has received the most attention for cancer gene therapy. in this study, the role of dendrosome and lipofectin mediated normal cdna of tp53 into molt-4, ccrf-cem(t-iymphoma) and k562 cell lines was assessed. material and methods: at first, ccrf-cem, mol t-4 and k...

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...

It has been reported that trypan blue, a diazo dye with polyamphipathic structure, can inhibit the coupling of receptors to G-proteins. The present study was carried out to investigate the effect of trypan blue on the actions of adrenoceptor agonists in the guinea-pig atrium. Trypan blue (10 and 100 microM) antagonized the positive inotropic effects of isoprenaline and dobutamine by shifting th...
