Optical coherence tomography (OCT) has advanced significantly over the past two decades and is currently used extensively to monitor the internal structures of organs, particularly in ophthalmology and dermatology. We used ethylenediamine tetra-acetic acid (EDTA) to decalcify the bony walls of the cochlea and investigated the inner structures by deep penetration of light into the cochlear tissu...

Obtaining the cleanest canal possible before obturation is one of the goals of endodontic treatment. The purpose of this study was to compare the smear layer removal capability of ethylenediamine tetra-acetic acid (EDTA) application with passive ultrasonic and cotton wrapped on reamer activation. Twelve extracted human teeth with single root canals were used for the study. They were conventiona...

AIM The present study was designed to investigate the effects of estradiol-ethylenediamine derivative on perfusion pressure and coronary resistance in rats. An additional aim was to identify the molecular mechanisms involved. METHODS The Langendorff model was used to measure perfusion pressure and coronary resistance changes in isolated rat heart after estradiol-ethylenediamine derivative alo...

Knowledge of hydrogen bonds is important in a wide range of scientific fields. However, information on the electronic state of hydrogen bonded molecules in liquids and solutions is still limited. We applied X-ray emission and absorption spectroscopy to observe the electronic state around oxygen of water and investigate the solvent dependence of occupied and unoccupied valence electronic states ...

Hollow CdS nanoboxes, having paper-thin walls of well-defined facets, were synthesized at 170 degrees C via a simple reaction using Na(2)SeO(3) for interior quasitemplates and ethylenediamine for exterior molecular templates.

We describe the synthesis of N -functionalised phosphinecarboxamides obtained by reaction 2-phosphaethynolate anion (PCO ? ) with diamines, specifically hydrazine, methylenediamine and ethylenediamine.

The asymmetric C atom in the title compound, C(21)H(17)BrClNO, is in a slightly distorted tetra-hedral environment and the NH unit adopts a gauche orientation with respect to the CO group. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers.
