In this study, stress distribution in a maxillary central incisor that was subjected to endodontic treatment and various post and core applications was determined by using a three-dimensional finite-element method. Cast gold post and gold core and different combinations of prefabricated stainless-steel post, or a prefabricated titanium post with amalgam or composite cores were considered. In all cases, the tooth was assumed to have a porcelain crown. The primary purpose of the study was to evaluate the stress distribution due to simulated biting forces and thus investigate the reliability of different post and core applications. It was found that, within the limitations of the study, the cast gold post and gold core application yielded the best result. The second purpose of the study was to highlight the importance of using a unique stress value, which contains the effects of all the possible stress components existing upon loading in the determination of a possible failure. A resultant stress value and all the constituent components were shown in detail, and it was proved that an estimation independently based on an individual component might lead to erroneous results.

Novel bioconversion reactions for the syntheses of a-hydroxy ketones Ayhan, Peruze; Demir, Ayhan Sıtkı; Department of Biotechnology (2009) The objective of the study presented here was to develop either enzymatic or whole cell mediated green procedures for the syntheses of a-hydroxy ketones. Production of optically active synthons is crucial for the preparation of fine chemicals. Enzymes and whole-cell biocatalysts have proven to be excellent vehicles with their chiral nature for the biotransformations. Under the light of this discussion, firstly benzaldehyde lyase [BAL, (EC 4.1.2.38)] was used in novel C-C bond formation reactions to obtain i...
Investigation of docetaxel and doxorubicin resistance in mcf-7 breast carcinoma cell line Darcansoy İşeri, Özlem; Gündüz, Ufuk; Department of Biotechnology (2009) Multidrug resistance phenotype of tumor cells describes resistance to wide range of structurally unrelated anticancer agents and is a serious limitation to effective chemotherapy. It is a multifactor yet not fully elucidated phenomenon by the involvement of diverse cellular pathways. Aim of this study was to investigate the resistance mechanisms developed against docetaxel and doxorubicin that are widely used in the treatment of breast cancer in model cell line MCF-7. Resistant sublines were developed by ap...
ANALYSIS OF STRESS-DISTRIBUTION IN A VERTICALLY CONDENSED MAXILLARY CENTRAL INCISOR ROOT-CANAL YAMAN, SD; ALACAM, T; Yaman, Yavuz (Elsevier BV, 1995-06-01) In this study, the stress distribution in a maxillary central incisor subjected to an endodontic treatment was determined by using a three-dimensional finite-element method, The tooth had a variable root canal cross-sectional area, and the canal was assumed to be filled with vertical condensation. The Clinical practice was simulated by considering the obturation in successive stages, The main aim of the study was to investigate the possibility of fracture due to the obturation process, It was found that, wi...
Investigation of polymerization of benzoxazines and thermal degradation characteristics of polybenzoxazines via direct pyrolysis mass spectrometry Fam, Shahla Bagheri; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2012-10-01) Polymerization of benzoxazines and thermal degradation mechanisms of polybenzoxazines were investigated using the direct pyrolysis mass spectrometry (DP-MS) technique. The benzoxazine structures were based on phenol and aniline and on bisphenol-A and methylamine or aniline. Polymerizations of the benzoxazines were carried out by curing them at elevated temperatures without addition of initiator or catalyst. DP-MS data showed the presence of chains generated by opposing polymerization reaction pathways indic...
Determination of metabolic bottlenecks using reaction engineering principles in serine alkaline protease production by recombinant bacillus sp. Telli, İlkin Ece; Çalık, Pınar; Department of Chemical Engineering (2004) In this study, firstly, bioprocess characteristics for Serine Alkaline Protease (SAP) production, using recombinant Bacillus subtilis carrying pHV1431::subC, were examined. The cell concentration, substrate concentration, SAP activity and SAP synthesis rate profiles demonstrated that the system reaches to a steady state in terms of cell growth and SAP synthesis between t=15-25 h, therefore, this time interval is appropriate to employ both metabolic flux analysis and metabolic control analysis, which apply s...
