Objective Supraventricular arrhythmias are commonly detected in patients with anti-mitochondrial antibody M2 (AMA-M2)-associated myopathy. However, the prevalence of supraventricular arrhythmias in unselected AMA-M2-positive patients and the impact of AMA-M2 on supraventricular arrhythmias have yet to be fully investigated. Methods We analyzed 384 patients (116 men; age, 60 [48-69] years), who ...
در این تحقیق نانوذرات سیلیکا به روش رسوب‌گذاری نیمه‌پیوسته تهیه شد. تأثیر عوامل مختلف مانند زمان واکنش، غلظت محلول واکنش‌گرها و pH بر ویژگی‌های جذب روغن و مساحت سطح ویژه نانوذرات سیلیکای تهیه شده در قالب یک طرح آزمون سه عاملی با دو سطح در هر عامل مورد بررسی قرار گرفت. نتایج آماری نشان داد که مهمترین عامل تأثیرگذار بر ویژگی جذب روغن نمونه‌ها، اثر متقابل pH و زمان واکنش است و هر سه عامل زمان واکن...
Background: Obesity is a growing problem in industrial nations. The aim of this study was to determine the relationship between the body mass index (BMI) and the pattern of injury after polytrauma. Methods: This retrospective study included 651 patients with an injury severity score (ISS) ≥16 and aged ≥16 years who were subdivided into three groups: BMI < 25 kg/m2, BMI 25–30 kg/m2, and BMI > 30...
We investigate the following question: “Given an intersecting multi-hypergraph on n points, what fraction of edges must be covered by any of the best 2 points?” (Here “best” means that together they cover the most.) We call this M2(n). This is a special case of a question asked by Erdős and Gyárfás [1] (they considered r–wise intersecting and the best t points), and is a generalization of work ...
Distinct hemodynamic and volume characteristics have been suggested for established hypertension in severe obesity, namely, a high cardiac output, and expanded blood volume, and a normal peripheral resistance. To evaluate whether hypertension in moderately obese patients represents a separate entity that can be defined by hemodynamic and volume profiles, we studied these in 50 such patients and...
