Biosynthesized silver nanoparticles for electrochemical detection of bromocresol green in river water.

In this study, silver nanoparticles (AgNPs)-based electrochemical sensor has been reported for assessing bromocresol green (BG) in river water. Firstly, AgNPs were greenly produced using the aqueous extract of leaves. Then, the AgNP-modified glassy carbon (GC) electrode was prepared using the sticking method.

Three-Dimensional Nonlinear Contact Finite Element Analysis of Mandibular All-on-4 Design.

The All-on-4 design was used successfully for restoring edentulous mandible. This design avoids anatomic cripples such as inferior alveolar nerve by tilting posterior implants. Moreover, tilting posterior implants of All-on-4 design had a mechanical preference than the conventional design.

RUNX2 gene status in a cleidocranial dysplasia patient without supernumerary teeth.

Objective: This study sought to perform mutational analysis of the RUNX2 gene in an 8-year-old girl with a diagnosis of cleidocranial dysplasia (CCD) without supernumerary teeth (proband) and her parents, plus in age and gender matched control subjects.

Methods: Ethical approval and informed consent was obtained for this study. Blood samples were obtained and the isolated DNA was used to amplify exons 0-7 of the RUNX2 gene using specific primers, which was subsequently sequenced.
