objective: amiodarone as an iodinated benzofuran derivative is a potent antiarrhythmic agent currently used for the treatment of ventricular arrhythmias. pulmonary toxicity is one of the complications of amiodarone therapy. the aim of this study was to determine the toxicity of amiodarone for pneumocytes. materials and methods: 14 male white new zealand rabbits were divided in a control group a...

purpose: bipolar disorders of complex and multi-dimensional nature necessitate new therapies.   this research compared the effect of meta-cognitive and psycho-educational family therapy on   dysfunctional attitudes of bipolar patients.   materials and methods: this was a semi-empirical research with pretest-posttest design, using   control group. from among the bipolar woman who had referred to...

Gold nanoparticles (AuNPs) are a popular material in the field of nanoscience because their excellent biocompatibility and unique physical chemical properties, have been widely used biomedical field. AuNPs simple preparation method, controllable shape size, high electron density atomic number, superparamagnetic radiation sensitization effect, optical absorbance can be adjusted to required biolo...

Background: Sodium valproate (VPA), an anticonvalsant drug, has been reported to stimulate viral replication.  A combination therapy with VPA and acyclovir (ACV) is used for the treatment of herpesvirus encephalitis, the commonest sporadic encephalitis of viral origin. Objective: To determine a possible interaction between VPA and ACV leading to a modification of antiviral activity of ACV. Meth...

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

We report studies of the surface fringe structures and tunable bandgap width of atomic-thin boron nitride nanosheets (BNNSs). BNNSs are synthesized by using digitally controlled pulse deposition techniques. The nanoscale morphologies of BNNSs are characterized by using scanning electron microscope (SEM), and transmission electron microscopy (TEM). In general, the BNNSs appear microscopically fl...

High electric fields were delivered to specimens during imaging in the transmission electron microscopy (TEM) chamber to reveal details of electric field-induced phenomena in ferroelectric oxides. These include the polarization switching in nanometer-sized ferroelectric domains and the grain boundary cavitation in a commercial lead zirconate titanate (PZT) polycrystalline ceramic, the domain wa...

In this work, we introduce a maskless, resist-free rapid prototyping method to fabricate three-dimensional structures using electron beam induced deposition (EBID) of amorphous carbon (aC) from a residual hydrocarbon precursor in combination with metal-assisted chemical etching (MaCE) of silicon. We demonstrate that EBID-made patterned aC coating, with thickness of even a few nanometers, acts a...
