the aim of this study is comparison of soil characteristics and biodiversity in plantation of bald cypress and caucasian alder forest stands in kludeh region (mazandaran province). in order to study biodiversity in forest stands and control region, 10 sample plots (releve) were selected and the name and abundance of plant species of the forest floor were recorded. biodiversity of herbal plants ...
background: selenium (se) is an essential trace element mainly obtained from seafood, meat, and cereals. se deficiency has been identified as a major contributing factor in the pathogenesis of certain congestive heart failure (chf) syndromes. since there is controversy over the prevalence of se deficiency among patient with chf, the aim of this study was to assess the serum se concentrations in...
introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...

hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...
effect of extracellular calcium depletion on atrial natriuretic factor secretion and gene expression
extracellular ca 2+ concentration ([ca2+]o) may be one of the factors affecting atrial natriuretic factor (anf) release. in the previous studies, there are opposite reports about the effect of [ca2+]o on anf secretion. therefore, the effect of [ca2+]o depletion on anf secretion and gene expression was studied in the present research. isolated right atria from rats were perfused for 6 and 2 hour...
Introduction: Cardiovascular problems and atrial fibrillation is one of the most prevalent secondary consequences in hemodialysis patients. This study aimed to examine the effect of high intensity interval training on the level of atrial fibrillation, fibroblast growth factor 23 and Klotho in male rats with chronic kidney disease. Methods: In this study, 30 male rats Wistar (7-8 weeks) were ra...
Cold rolling process is a complicated process which can be optimized by changing in variables and settings. This paper presents a set-up optimization system developed to calculate reductions and inter-stand tensions for each stand of a five stand tandem cold mill. The main objective in this optimization is minimization of power consumption. First, by using the analytical method, the equations ...
بررسی شیوع لخته دهلیز و گوشک دهلیز چپ در بیماران مراجعه کننده با فلوتر دهلیزی بر حسب بیماری زمینهای
Introduction: Most current evidence suggests the risk of left atrial and or auricular thrombi(LA &LAA) in patients with atrial flutter rhythm is similar to patients with atrial fibrillation, but there is still uncertainty in the risk level and the patient's need to receive anticoagulant therapy. Different studies report various frequencies for atrial thrombi and left atrial spontaneous echo-con...
introduction: atrial fibrillation (af) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. the goal of this article is to clarify an overview of the evidence linking inflammation to af existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of af by modulating inflammatory pathways. mat...
