Spontaneous coronary artery dissection (SCAD) is known to be a rare but fatal cause of acute coronary syndromes. It is more frequent in young women, particularly in the peripartum period. Intravascular ultrasound (IVUS) has an important role in the diagnosis and management of SCAD. Intramural hematoma that occurs between adventitial and media layer of the vessel wall may occlude the true lumen....
D6WE (Diet 6 with enzyme); D7NE (Diet 7 with no enzyme); and D8WE (Diet 8 with enzyme). Each of these diets was fed ad – libitum to the experimental broiler finishers. The trial lasted twenty eight days. The feed intake, weight gain, cost per gain (N/Kg) and carcass characteristics were the parameters evaluated. There were significant differences (P < 0.05) in feed intake, weight gain and carca...
conclusions alterations were present in both the aspect and spacing of collagen fibrils and in the shape of elastic fibers. the present familial combination of scad and edsh, with almost similar ultrastructural features suggests a possible connection between both conditions. case presentation we present a woman with scad and her five close relatives showing obvious or suggestive signs of edsh. ...
spontaneous coronary artery dissection (scad) is a rare and important cause of acute coronary syndrome and sudden cardiac death. various etiologies are thought to be responsible for this condition, among which underlying atherosclerosis seems to be the most common. scad is predominant in women and is usually diagnosed via coronary artery angiography. therapeutic interventions include medical th...
The widely used least absolute deviation (LAD) estimator with the smoothly clipped (SCAD) penalty function (abbreviated as LAD-SCAD) is known to produce corrupt estimates in presence of outlying observations. problem becomes more complicated when number predictors diverges. To overcome these problems, LAD-SCAD based on sure independence screening (SIS) technique put forward. SIS method uses ran...
BACKGROUND AND PURPOSE Observations in patients with arterial aneurysms, fibromuscular dysplasia, and spontaneous cervical artery dissection (sCAD) indicate that protease inhibitor deficiency might boost the enzymatic destruction of arterial tissue and increase the risk of these arterial wall diseases. Here we present the first large investigation of the protease inhibitor hypothesis in patient...
We have shown previously that a variant allele of the short-chain acyl-CoA dehydrogenase ( SCAD ) gene, 625G-->A, is present in homozygous form in 7% of control individuals and in 60% of 135 patients with elevated urinary excretion of ethylmalonic acid (EMA). We have now characterized three disease-causing mutations (confirmed by lack of enzyme activity after expression in COS-7 cells) and a ne...
با پیشرفت علوم مختلف و انجام تحقیقات پیشرفته، هر روز انواع مختلفی از داده ها مطرح می شوند که نیازمند روش های قابل اطمینان برای تجزیه و تحلیل هستند. در این بین روش های رگرسیونی بعنوان یکی از پرکاربردترین روش های تجزیه و تحلیل داده ها شناخته شده است. انتخاب و برآورد متغیرهایی که می بایست درون مدل رگرسیونی قرار گیرند جزء مهمترین بخش های مدل سازی رگرسیونی است. روش های متداول که در زمینه برآوردیابی ...
برداشت بیش از حد از آب های زیرزمینی دشت تایباد به منظور افزایش عملکرد محصولات و سود خالص کشاورزان، باعث افت مستمر سطح آب، منفی شدن بیلان و افزایش شدید کسری مخزن، نامطلوب شدن کیفیت آب و هجوم جبهه شوری شده است. این عوامل حاکی از لزوم مدیریت منابع آب زیرزمینی در این منطقه می باشد. به طوری که برداشت از آب زیرزمینی در حد بهینه صورت گرفته و در عین حال سود اقتصادی زارعین منطقه افزایش یابد. در این مطال...
BACKGROUND Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic but a rare and extremely dangerous clinical entity, it has a high prevalence in young female population with acute myocardial infarction (AMI). The previous reports were restricted to other countries' population, but rare in China. Hence, this study aimed to focus on the characteristics of SCAD as a cause of young ...
