Cleidocranial dysplasia with a rare mutation:Study of a family with review of literature

Open Journal of Stomatology 2013年第8期3卷 402-410页

Introduction: The present study was aimed at advancing the understanding of the pathogenesis of cleidocranial dysplasia (CCD) by presenting a case study based on history, physical examination, typical radiological features, and molecular analysis and a review of the literature. Methods: This study began with a 23-year-old boy (proband) who was referred to the department of oral and maxillofacial radiology with chief complaint of the upper-left first molar tooth and routine dental examination. While evaluating the panoramic radiograph, the patient had approximately 57 teeth in his both of the jaws. Clinical, radiographical and molecular features of the proband, two siblings and their parents were examined and then, DNA analysis was performed. Results: Overall, we present 3 CCD patients with a mutation in the VWRPY motif. The deletion of c. 1754_1757 delTTTG (NM_001024630.2) is determined and it leads to a frame shift mutation and stop codon, p. V585Gfs56X. Conclusions: The present study emphasized the importance of further clinical and molecular investigation when even a single case of CCD is identified within a family. This is the first study performed in Turkey about a family with a mutation in the VWRPY motif. Genotype-phenotype association studies in individuals with CCD are necessary to provide important insights into molecular mechanisms associated with this disease.

One-Pot Synthesis of Pyrido[2,3-d]pyrimidines Catalyzed by Bismuth(III)Triflate

引用

International Journal of Organic Chemistry 2022年第1期12卷 11-27页

作者： Deniz Saglam Zuhal turgut Department of Chemistry Faculty of Art and Sciences Yildiz Technical University Davutpasa Campus Istanbul Turkey

Synthesis of uracil derivatives, such as pyrido[2,3-d]pyrimidine, is very important for the pharmaceutical industry due to their many biological activities. In our continuing efforts into the development of new synthetic strategies for the preparation of heterocyclic compounds in this study, we performed reflux reactions with the catalyst Bi(OTf)3 by using a one-pot, threecomponent method. The one-pot, three-component condensation of 6-amino-1,3-dimethyluracil, with arylaldehydes and malononitrile to generate a series of 7-aminopyrido[2,3-d]pyrimidine-6-carbonitrile derivatives has been carried out in the presence of bismuth triflate as a green and reusable catalyst.

Influences of Pr and Ta doping concentration on the characteristic features of FTO thin film deposited by spray pyrolysis

引用

Chinese Physics B 2015年第10期24卷 414-422页

作者： Güven turgut Adem Koqyigit Erdal Snmez Erzurum Technical University Science FacultyDepartment of Basic Sciences Igdir University Engineering FacultyDepartment of Electrical Electronic Engineering Ataturk University Kazim Karabekir Education FacultyDepartment of Physics

The Pr and Ta separately doped FTO（10 at.% F incorporated Sn O2） films are fabricated via spray pyrolysis. The microstructural, topographic, optical, and electrical features of fluorine-doped TO（FTO） films are investigated as functions of Pr and Ta dopant concentrations. The x-ray diffraction（XRD） measurements reveal that all deposited films show polycrystalline tin oxide crystal property. FTO film has（200） preferential orientation, but this orientation changes to（211） direction with Pr and Ta doping ratio increasing. Atomic force microscopy（AFM） and scanning electron microscopy（SEM） analyses show that all films have uniform and homogenous nanoparticle distributions. Furthermore, morphologies of the films depend on the ratio between Pr and Ta dopants. From ultraviolet-visible（UV-Vis） spectrophotometer measurements, it is shown that the transmittance value of FTO film decreases with Pr and Ta doping elements increasing. The band gap value of FTO film increases only at 1 at.% Ta doping level, it drops off with Pr and Ta doping ratio increasing at other doped FTO films. The electrical measurements indicate that the sheet resistance value of FTO film initially decreases with Pr and Ta doping ratio decreasing and then it increases with Pr and Ta doping ratio increasing. The highest value of figure of merit is obtained for 1 at.% Ta- and Pr-doped FTO film. These results suggest that Pr- and Ta-doped FTO films may be appealing candidates for TCO applications.
