Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice and is associated with a notable increase in morbidity and mortality. Although there have been considerable advances in the treatment of AF, the results of drug treatment and ablation remain suboptimal.1 This is largely due to the fact that there is still little understanding of the mechanisms responsible for the i...

The possible enzymatic activities of neuro- and cytoglobin as well as their potential function as substrates in enzymatic reactions were studied. Neuro- and cytoglobin are found to show no appreciable superoxide dismutase, catalase, and peroxidase activities. However, the internal disulfide bond (CD7-D5) of human neuroglobin can be reduced by thioredoxin reductase. Furthermore, our in vivo and ...

in order to evaluate the effect of substrate and enrichment material on biological efficiency (be) and other physical and chemical propertiese of medicinal mushroom shiitake (lentinula edodes) an investigation was perfomed as factorial experiment in completely randomized designe with four replications in khorramabad city of lorestan continent iran. experimental factors were substrate in three l...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...

in this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (aisi 316) and ferritic (aisi 430) stainless steel substrates have been investigated using torch technique. the effects of substrate surface preparation has also been studied. the quality of coatings produced has been examined using optical and scanning electron microscopy, x-ray diffraction, raman spectrosc...

For the first time, this research reports the formation of nanoporous layers of metals on the surface of metal substrates by Raney method and their conversion to corresponding porous perovskite layers. The noble metals doped perovskites are used as catalytic converter for reducing automotive pollutants. The use of perovskite as a substrate for the noble metals can reduce the need for such metal...
