BACKGROUND Protein-losing enteropathy (PLE) is a late complication of the Fontan type surgery for univentricular heart characterized by massive enteric protein loss. The pathogenesis of PLE is not fully understood, and it is unclear why the onset of PLE varies widely and occurs months or even years after surgery. Besides characteristic laboratory findings, a typical cellular feature concerns th...
Previously, powdered persimmon leaves have been reported to have glucose- and lipid-lowering effects in diabetic (db/db) mice. As persimmon leaf is commonly consumed as tea, an aqueous extract of persimmon leaves (PLE) was prepared and its anti-diabetic efficacy was investigated. In the present study, PLE was tested for its inhibitory activity on α-glucosidase in vitro. An oral maltose toleranc...
رشد روزافزون مناطق مواجه با محدودیت منابع آب، اتخاذ راهبردهای مدیریت سازگارانهی آب را در ورای روشهای سنتی مدیریت عرضه و تقاضا، مُبدل به امری الزامی نمودهاست. تخصیص آب بهعنوان یک روش مدیریتی مُنعطف، از این امکان برخوردار است که در هنگامهی تغییرات اقتصادی – اجتماعی، اقلیمی و شرایط محیط زیستی، بهعنوان ممری جهت مقابله با محدودیت منابع آب، عمل نماید. در تحقیق حاضر با بهرهگیری از سیستمهای پویا...
Previous researches have widely demonstrated that the interference from peripheral distractor will decrease when the task load is high. However, no study to date has paid attention to the individual differences in perceptual load effect (PLE) and little is known of spontaneous brain activity associated with PLE during resting state. To investigate this issue, we used resting-state functional Ma...

BACKGROUND Hypovitaminosis D has previously been shown to be prevalent amongst dogs with protein losing enteropathy (PLE). The hypothesis of this study was that Low 25-hydroxyvitamin D (25(OH) D) serum concentrations could be a risk factor for negative outcome in dogs with PLE. Forty-three dogs diagnosed with PLE (2005-2014) and which serum Vitamin D serum concentrations were collected and arch...
Today’s market expectations force organizations to invent and provide new products in short time and thus to speed up their product and software development. On the one hand, Product Line Engineering (PLE) is a promising approach that is believed to shorten time to market and increase high quality of products. On the other hand, agile methods aim at reducing time to market and increasing qualit...
