anotomical boundary of atrioventricular node reentrant tachycardia (avnrt) is composed of fast and slow pathways right atrium in upper turnaround and common distal pathway in lower turnaround. we performed electophsiologic study (eps) in 152 patients and could show the existence of distal common pathway with decremental conduction properties in approximately 40 patients.

background: the wnt/β- the wnt/β-catenin signaling pathway is involved in many developmental processes in both fetal and adult life; its abnormalities can lead to disorders including several types of cancers and malfunction of specific cells and tissues in both animals and humans. its role in reproductive processes has been proven. objective: this study was designed to evaluate the expression o...

accessory pathways (ap) are abnormal myocardial connections between atria and ventricles with electrical conductive properties. we performed radio frequency (rf) catheter ablation in 66 patients with manifest ap at dr.shariati hospital during 5 years. bipolar mapping was used in 48 patients and unipolar mapping in 18 patients of find the best site for rf energy delivery. we calculated total dur...

objective: prostate cancer is the fifth most common cancer. in 2012, it was the second leading cause of cancer death for men worldwide. the pi3k/akt pathway plays an essential role in pathogenesis of prostate cancer; the key role of this pathway in cancer progression makes it an attractive target for prostate cancer therapy. micrornas (mirnas) that regulate gene expression have a special abilit...

abstract: fifteen non-aflatoxigenic strains of aspergillus flavus, represent a wide range of geographic regions of iran (six provinces include fars, ardebil, guilan, golestan, kerman and semnan) and vegetative compatibility groups (vcgs), were collected from corn (zea mays l.), peanut (arachis hypogaea l.) and pistachio (pistachia vera l.) soils and kernels, were screened for the presence of af...

inflammatory condition is the consequence of defensive mechanism of immune system against viral and bacterial infection, tissue injury, uv radiation, stress and etc. persistently acute inflammation leads to chronic phase which is characterized by production of pro-inflammatory mediators from t cells. these molecules (e.g. il-6, tnf-α, il-1β and il-17) are mostly pleiotropic cytokines involved i...

ophiocoma erinaceus muller &troschel; (ophiocomidae) is part of the extensive group of echinoderm that contains bioactive metabolites. as, the anti cancer potential of brittle star saponin has not been reported against cervical cancer, the present study was conducted to evaluate the anticancer effect of extracted crude saponin. saponin extraction was conducted using conventional method such as ...

background: acute lymphoblastic leukemia (all), the most common childhood cancer with a peak incidence in children from 2-5 years old, might be associated with poor prognosis and resistance to therapy in specific cytogenetic backgrounds. foxo3a, a member of the forkhead class 'o' (foxo) transcription factors, is a main downstream target of pi3k/akt pathway which regulates different variety of b...

one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...
