به منظور مطالعه اثر باکتریهای محرک رشد گیاه بر عملکرد کمی و کیفی دو رقم برنج، آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در 4 تکرار در سال زراعی 1388 در مزرعه تحقیقاتی موسسه ی تحقیقات برنج کشور در استان گیلان به اجرا در آمد. در این تحقیق، عامل رقم در 2 سطح (هاشمی و خزر) و تلقیح بذر با باکتری محرک رشد در 8 سطح (p. fluorescents strain 93 , p. fluorescents strain 103, p.fluorescents ...
The left atrium (LA) serves as a reservoir of blood draining from the pulmonary veins during ventricular systole, a conduit of blood during ventricular diastole, and a booster pump of blood flow during atrial contraction. Normal LA function is important in maintaining adequate cardiac performance, and it becomes abnormal in various cardiac or extra-cardiac conditions. The abnormality of LA func...
Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine model, we investigated the influence of acute dynamic preload reductions on left ventricular strain and strain rate and their relation to the pressure-conductance catheter-der...
Background Because conventional echocardiographic parameters have several limitations, strain echocardiography has often been introduced in clinical practice. However, there are also obstacles in using it in clinical practice. Therefore, we wanted to find the current status of awareness on using strain echocardiography in Korea. Methods We conducted a nationwide survey to evaluate current use...
Echocardiographic strain and strain-rate imaging (deformation imaging) is a new non-invasive method for assessment of myocardial function. Due to its ability to differentiate between active and passive movement of myocardial segments, to quantify intraventricular dyssynchrony and to evaluate components of myocardial function, such as longitudinal myocardial shortening, that are not visually ass...

BACKGROUND Hyperadrenocorticism (HAC) is associated with an increased prevalence of hypertension. This study investigated the left ventricular function using two-dimensional speckle-tracking echocardiography (2D-STE) in small breed dogs affected with spontaneous HAC. Age-matched healthy controls (n = 9), dogs with pituitary-dependent hyperadrenocorticism (PDH, n = 10), and dogs with adrenal-dep...
