Background & Objective : Several indices have been introduced to estimate arterial stiffness that based on changes in brachial blood pressure. But because of the error resulted by the substitution of brachial blood pressure instead of the other central arteries, such as carotid, it will be very important to present elastic parameter based on the mechanical models without any emphasis on brach...
Measurement of arterial input function (AIF) for quantitative positron emission tomography (PET) studies is technically challenging. The present study aimed to develop a method based on a standard arterial input function (SIF) to estimate input function without blood sampling. We performed (18)F-fluolodeoxyglucose studies accompanied by continuous blood sampling for measurement of AIF in 11 rat...
UNLABELLED A challenging aspect of managing patients on venoarterial extracorporeal membrane oxygenation (V-A ECMO) is a thorough understanding of the relationship between oxygenated blood from the ECMO circuit and blood being pumped from the patient's native heart. We present an adult V-A ECMO case report, which illustrates a unique encounter with the concept of "dual circulations." Despite bl...
UNLABELLED Measurement of the arterial input function is essential for quantitative assessment of physiological function in vivo using PET. However, frequent arterial blood sampling is invasive and labor intensive. Recently, a PET system has been developed that consists of two independent PET tomographs for simultaneously scanning the brain and heart, which should avoid the need for arterial bl...
Background and purpose : Arterial blood gases ( Arterial blood gas [ABG] ) One of the most important Laboratory tests to determine the status PH the amount of oxygen and carbon dioxide blood levels of bicarbonate. Also, hemoglobin and serum lactate and electrolytes and also won the Test . Height and air pressure can vary on ABG and its surface, low pressure conditions at high altitude pilots pl...
introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...

Background: Late preterm neonates may have the external appearance and behavior similar to their counterparts.However, they are susceptible to various neonatal morbidities , due to their physiological and metabolical immaturity.To assess the correlation between cord blood arterial lactate levels and base excess with the development ofrespiratory distress in late preterm neonat...
