background: noninvasive techniques for the localization of the accessory pathways (aps) might help guide mapping procedures and ablation techniques. we sought to examine the diagnostic accuracy of strain imaging for the localization of the aps in wolff-parkinson-white syndrome. methods: w e prospectively studied 25 patients (mean age = 32 ± 17 years, 58.3% men) with evidence of pre-excitation o...

Background & Objective: Thyroid hormones have an important role in the regulation of lipid metabolism. Subclinical hypothyroidism (SCH), defined as a mild increase in thyroid-stimulating hormone (TSH) and normal level of thyroxine (T4), could be associated with altered lipid profile. The current study aimed at assessing the association between SCH and ...

background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...

Background: Coronary artery disease is considered as the most common cause of death in all societies including Iran. This study seeks to compare the new risk factors of coronary-artery diseases in obese adolescents and control group.Methods: In this cross-sectional study, amongst the obese adolescents registered in the nutrition clinic of Ghaem Hospital, 80 individuals were selected. As the con...

background: metal ions effect on homeostasis of alzheimer’s disease (ad) patients. the aim of this study was to assess the metal ions (iron, zinc and copper) and cbc in patients with ad in comparison with normal range. methods: the samples of study were 17 patients with ad in tehran’s aging centers in 2015, selected as an access sample. blood samples were analyzed in a pathobiology laboratory. ...

Abstract The main objective of this study was to examine the relationship between Value at Risk (VaR) and expected returns from 2002 to 2013 in Tehran’s Stock Exchange. In this study parametric value at risk, which considers the distribution of returns as normal and the historical value at risk as abnormal, was used to test the presence of the volatility anomaly in the companies listed i...

objective: atorvastatin has the pleiotropic effects, including anti-inflammation and antioxidant. therefore, this study considered to examine the effects of atorvastatin on nf-қb expression, as a main transcription factor for expression of inflammatory cytokines, in hyperglycemia-induced nephropathy in rat. materials and methods: twenty four male wistar rats were randomly divided into four grou...

background the nasal septal deviation (nsd) is one of the major causes of nasal obstruction. this condition increases upper airway resistance. in this study we evaluated the mean pulmonary artery pressure (mpap) in patients with markedly deviated septum. methods sixty two patients with nsd (age range: 26-45 years, 34 men and 28 women) were included in the study. mean pulmonary artery pressure w...
