افزایش فعالیت­های کشاورزی برای پاسخ­گویی به نیازهای اولیه­ی انسان­ها و به تبع آن استفاده روزافزون از سموم شیمیایی برای مقابله با آفات موجود در این صنعت، توجه ویژه­ای را به خود جلب کرده است. استفاده از این سموم منجر به آلودگی محیط زیست خواهد شد، در همین راستا این مقاله سعی دارد تا با طراحی الگوی مالیاتی مناسب، از استفاده­ی بی­رویه این سموم جلوگیری کرده و آلودگی ناشی از آن را نیز کاهش دهد. مبانی ...

Background Consuming watercress is thought to provide health benefits as a consequence of its phytonutrient composition. However, for watercress there are currently limited genetic resources underpinning breeding efforts for either yield or phytonutritional traits. In this paper, we use RNASeq data from twelve watercress accessions to characterize the transcriptome, perform candidate gene minin...

BACKGROUND Severe aortic stenosis (AS), leads to pathological left ventricular remodeling that may worsen with concomitant overweight and obesity (OW/O). METHODS We aimed to prospectively analyze the impact of OW/O on ventricular remodeling in severe AS, by evaluating the percentage of intraendomyocardial fibrosis (PIEF) and the percentage of infiltrating intraendocardial lipid vacuoles (PIEL...

BACKGROUND Aortic stiffness impairs optimal ventricular-vascular coupling and left ventricular systolic function, particularly in the long axis. Left ventricular global longitudinal strain (GLS) has recently emerged as a sensitive measure of early cardiac dysfunction. In this study, we investigated the relation between aortic stiffness and GLS in a large community-based sample. METHODS AND RE...

AIMS Heart failure patients with reduced and preserved left ventricular (LV) ejection fraction (EF) show reduced exercise capacity. We explored the relationship between exercise capacity and systolic and diastolic myocardial function in heart failure patients. METHODS AND RESULTS Exercise capacity, by peak oxygen uptake (VO2), was assessed in 100 patients (56 ± 12 years, NYHA functional class...

BACKGROUND Global longitudinal strain (GLS), reflecting total shortening of the myocardium during the cardiac cycle, has emerged as a more precise myocardial function measure than left ventricular ejection fraction (LVEF). Longitudinal strain may be selectively affected in subclinical heart disease, even in the presence of normal LVEF. This study examines subclinical cardiac dysfunction, assess...

conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...

The Traveling Salesman Problem (TSP) is one of the most famous problems in combinatorial optimization. In this paper, we are going to examine how the techniques of Guided Local Search (GLS) and Fast Local Search (FLS) can be applied to the problem. Guided Local Search sits on top of local search heuristics and has as a main aim to guide these procedures in exploring efficiently and effectively ...

Background Significant coronary artery stenosis might cause persistently impaired longitudinal left ventricle (LV) function at rest. LV global longitudinal strain (LVGLS) can be accurately assessed by 2D speckle-tracking strain echocardiography(2D-STE). Objective We aimed to evaluate the diagnostic accuracy of LV global longitudinal strain obtained by 2D-STE in prediction of severity of CAD. ...
