Quantitative and Dynamic MRI Measures of Peripheral Vascular Function

Peripheral Vascular Function

Background. Blood pressure and total peripheral resistance increase with age. However, the effect of age on vasodilatory capacity has not been characterized. Methods and Results. To delineate the effects of aging, gender, and physical training on peripheral vascular function, we measured blood pressure during submaximal and maximal treadmill exercise and measured blood pressure, calf blood flow...

Lead, smoking, and peripheral vascular function.

Lead, Smoking, and Peripheral Vascular Function To the Editor: We read with interest the article by Argacha et al1 dealing with acute effects of passive smoking on peripheral vascular function. The authors presented data concluding that passive smoking specifically increases aortic wave reflection through a nicotinedependent pathway and impairs microvascular function, even after the end of the ...

diagnostic and developmental potentials of dynamic assessment for writing skill

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...

Dynamic Bayesian Information Measures

This paper introduces measures of information for Bayesian analysis when the support of data distribution is truncated progressively. The focus is on the lifetime distributions where the support is truncated at the current age t>=0. Notions of uncertainty and information are presented and operationalized by Shannon entropy, Kullback-Leibler information, and mutual information. Dynamic updatings...
