BACKGROUND AND PURPOSE Patients with arteriovenous malformation (AVM) are known to have an elevated risk of complications with conventional catheter angiography (CCA) but nonetheless require monitoring of hemodynamics. Thus, we aimed to evaluate both anatomy and hemodynamics in patients with AVM noninvasively by using contrast-enhanced MR angiography(More)
Upper extremity deep-vein thrombosis (UEDVT) is common and can cause important complications, including pulmonary embolism and post-thrombotic syndrome. An increase in the use of central venous catheters, particularly peripherally inserted central catheters has been associated with an increasing rate of disease.

We examined the effects of RT on oral glucose tolerance test (OGTT)-derived indices of muscle insulin sensitivity, hepatic insulin resistance, β-cell function, and skeletal muscle proteins related to glucose transport in overweight/obese, sedentary young men. Twenty-eight participants [median body mass index (BMI) 30.9 kg/m(2); age 22 yr] completed 12 wk of(More)
