The structure of the ground state exciton Cd(Se,Te) quantum dots embedded in ZnTe matrix is studied experimentally using photoluminescence spectroscopy and theoretically ${\bf k}\cdot{\bf p}$ configuration interaction methods. experiments reveal a considerable reduction fine-structure splitting energy with increase Se content dots. That effect interpreted by theoretical calculations to originat...

Sequence-dependent configuration changes and condensation of double-stranded poly(dG-dC).(dG-dC) (GC-DNA) and ds poly(dA-dT).(dA-dT) (AT-DNA) were observed by atomic force microscopy in the presence of Ni(II). Less condensing agent was required to generate configuration changes in GC-DNA as compared to AT-DNA. In the presence of Ni(II) cations, GC-DNA adopted a Z-type conformation and underwent...

Background and Objective: Several studies have found that diazepam decreases serum glucose. Meanwhile, glibenclamide is commonly used in diabetes treatment. The objective of this study was to survey the treatment impact of diazepam and glibenclamide on blood glucose and serum lipids in mice with type II diabetes. Materials and Methods: In this study, 32 male rats were divided into four groups,...

AIM To analyse the gutta-percha filled area of C-shaped molar teeth root filled with the modified MicroSeal technique with reference to the radiographic features and the C-shaped canal configuration. METHODOLOGY Twenty-three mandibular second molar teeth with C-shaped roots were classified according to their radiographic features as: type I--merging, type II--symmetrical and type III--asymmet...

INTRODUCTION The aim of this study was to evaluate root canal anatomy of mandibular first molars (MFM) in a selected Iranian Population using clearing technique. METHODS AND MATERIALS A total of 150 extracted MFMs were cleared. The root canal morphology (including the root numbers and root length) and the anatomy of the root canal system (including is the number and type of canals based on Ve...
