Effects of MoCl3 and NiCl2, originally incorporated as coloring agent, on the cellular response of3 mol% yttria stabilized zirconia (3Y-TZP) ceramics was investigated. MoCl3 and NiCl2-MoCl3incorporated, tooth-colored 3Y-TZP ceramics were produced through cold isostatic pressing at100 MPa followed by pressureless sintering at 1450°C for 2 h. Aging was performed on thesintered ceramics using distilled water in a reactor at 134°C at 2.3 bar pressure for 2 h. Thephases developed during different stages of processing were identified by X-ray diffraction(XRD) analysis. In vitro cell culture studies were carried out using L929 fibroblast cell line. Thecell viability and proliferation studies revealed that none of the specimens showed cytotoxicitywith respect to coloring. Confocal laser scanning microscope (CLSM) analyses suggested thatall of the specimens exhibited good in vitro cytocompatibility. Enhancement in cell attachment,adhesion, and proliferation was observed in all specimens via scanning electron microscope(SEM) analysis. Although the coloring process did not improve the proliferationperformance of the aged specimens, the incorporation of transition metals enhanced thein vitro performance of 3Y-TZP ceramics.

The effect of tin dioxide (SnO2) on the anatase-rutile phase transformation of titania (TiO2) in mica-titania pigments and their use in paint Topuz, Berna Burcu; Gündüz, Güngör; MAVİŞ, BORA; Colak, Uner (2011-08-01) The synthesis of mica-titania special effect pigment and the effect of rutile promoting additive, tin dioxide (SnO2), on the phase transformation of titanium dioxide (TiO2) were investigated. SnO2 coating with variable thicknesses on sieved and pre-treated muscovite mica prior to TiO2 coating yields a pearlescent pigment with higher rutile-to-anatase ratio. Different than what is reported in a few cases, not the co-deposition of SnO2 and TiO2, but the coating of SnO2 before TiO2 was found critical in obtain...
In vitro evaluation of zoledronic acid resistance developed in MCF-7 cells Kars, Meltem Demirel; Iseri, Ozlem Darcansoy; Ural, Ali Ugur; Gündüz, Ufuk (2007-11-01) Background: Zoledronic acid is an important osteotropic compound used in combination with anticancer agents to reduce the incidence of hypercalcemia and skeletal morbidity in patients with advanced breast cancer and bone metastases. Ineffectiveness of anticancer drugs during chemotherapy is a frequently observed situation in cancer chemotherapy. The resistance of tumor cells to more than one cytotoxic drugs is defined as multidrug resistance. Drug resistance may be caused by altered gene expression levels a...
In vitro Comparison of Autoclave Polymerization on the Transverse Strength of Denture Base Resins Durkan, Rukiye; ÖZEL, MEHMET BİROL; Bagis, Bora; Usanmaz, Ali (Japanese Society for Dental Materials and Devices, 2008-07-01) The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control. i.e.. conventional water bath to polymerize result by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at 60 degrees C for 30 minutes followed by 130 degrees C for 10 minutes; and (III) autoclave polymerization at 60 degr...
In vitro bone tissue engineering on patterned biodegradable polyester blends Kenar, Halime; Hasırcı, Vasıf Nejat; Toner, Mehmet; Department of Biotechnology (2003) This study aimed at guiding osteoblast cells on biodegradable polymer carriers with well-defined surface microtopography and chemistry, and investigating the effect of cell alignment on osteoblast phenotype expression. A blend of two different polyesters, one being natural in origin (PHBV) and the other synthetic (P(L/DL)LA), was used to form a film with parallel macro- (250 um wide) or microgrooves (27 jam wide) on its surface, by solvent casting on patterned templates. The micropatterned Si template was p...
A semi-empirical analysis of dye adsorption and electron transport in dye sensitized solar cells (DSSCs) Ameri, Mohsen; Samavat, Feridoun; Mohajerani, Ezeddin (2015-01-01) In order to provide a comprehensive understanding of dye adsorption parameters and their relation with the structural and transport properties of dye sensitized solar cells (DSSCs), a combination of experiments and modeling of the dye adsorption and electron transport characteristics with respect to the photoanode thickness was performed. The obtained experimental data include scanning electron microscopy (SEM) images, UV-Vis data, steady state current-voltage (J-V) characteristics and open circuit voltage ...
