Background and Aim: This study aimed to compare the cytotoxicity of AH Plus and DC Canal SE sealer after final setting. Materials and Methods: In this in vitro, experimental study, human gingival fibroblasts (HGFs) were cultured in Dulbecco’s modified Eagle’s medium supplemented with 10% fetal bovine serum, 100 U/mL penicillin, and 100 µg/mL streptomycin, and incubated at 37°C and 5% CO2. ...
MicroRNAs (miRNAs) are predicted to regulate approximately 30% of all human genes; however, only a few miRNAs have been assigned their targets and specific functions. Here we demonstrate that miR-24, a ubiquitously expressed miRNA, has an anti-proliferative effect independent of p53 function. Cell lines with differential p53 status were used as a model to study the effects of miR-24 on cell pro...
BACKGROUND IL-24, also termed MDA-7, is a member of the IL-10 family of cytokines. IL-24 is reported to be expressed in a series of cell lines, including keratinocytes as well as breast, lung and prostate cancer cells, but was primarily found in a human melanoma cell line. IL-24 is suggested to have many biological properties displaying anti-tumour effects via induction of apoptosis, suppressin...
S 1007 A total of 141 subjects, 61 to 97, with ENDOTHELIAL SYSTEM IN RABBITS. E. Mietkiewski and B. KofmirSski. From the School of Medicine, Szczecin, Poland. Acta Physiol. Pol. 19: 163-169, 1968. Phagocytosis of Congo Red was used as an indicator of activity of the RES in rabbits. A decrease in phagocytic activity was observed after ultraviolet irradiation. The possible mechanism was discussed...
Monomer adds to preformed structured oligomers of Abeta-peptides by a two-stage dock-lock mechanism.
Nonfibrillar soluble oligomers, which are intermediates in the transition from monomers to amyloid fibrils, may be the toxic species in Alzheimer's disease. To monitor the early events that direct assembly of amyloidogenic peptides we probe the dynamics of formation of (Abeta(16-22))(n) by adding a monomer to a preformed (Abeta(16-22))(n-1) (n = 4-6) oligomer in which the peptides are arranged ...
Purpose: To investigate the effect of different methods of synchronization on sheep granulosa cell cycle. Materials and Methods: Granulosa cells were aspirated from ovarian follicles and plated in a DMEM medium containing 15% FBS. Upon 70-80% confluency, the medium of the primarycultured as well as the passaged-5 cells were replaced with the medium containing either 0.5% FBS for 24, 48 and 72 h...
Cell damage induced by free radicals has been implicated as causal factor in a wide variety of human diseases such as cancer, neurodegenerative disorders. Scientific recognition of natural antioxidants may be helpful in preventing many diseases. Aqueous Date fruit extract (ADFE)- PC12 cell line. ADFE at concentrations of 0.1-10% containing 0.005% H2O2 and H2O2 at concentrations of 0.01-1% conta...
Superparamagnetic iron oxide nanoparticles (SPIONs) have made extensive advances in nanotechnology. The unique properties of these particles have expanded their application in various fields, including medicine. One of these applications is non-invasive analysis for cell tracking. However, the possibility of toxicity in cells is reported by these nanoparticles. Due to the fact that cellular dam...
Background: Recently, iron oxide nanoparticles have attracted attention in various diagnosis and treatment fields. The aim of the present study was to investigate the cytotoxicity of various concentrations and incubation times of dextran-coated iron oxide nanoparticles (DIONPs) on HeLa and MCF-7 cancerous cell lines. Methods: This in-vitro study was conducted at Pharmaceutical Sciences Researc...
Introduction: Breast cancer (BC) is the most common women cancer worldwide. Radiotherapy and chemotherapy are the two common treatment options but these techniques suffer low selectivity and adverse effects on surrounding normal tissues. Non- ionizing pulsed electromagnetic fields (PEMFs) in ultra-narrow band frequency and intensity have shown anticancer effects. Changing potas...
