BACKGROUND The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature. METHODS AND RESULTS To test whether atherosclerosis is associated with a functional abnormality of endothelium-mediated microvascular relaxation affecting coronary blood flow regulation, we compared corona...
Resistance training is a popular mode of exercise, but may result in stiffening of the central arteries. Changes in carotid artery diameter were determined using the cold pressor test (CPT), which results in production of nitric oxide via sympathetic activation and is one of the novel methods available for assessing endothelial function in the carotid artery. To investigate the effect of resist...
Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...
Multiple linear regression equations predicting total skeletal muscle (TM) and total skeletal fat-free muscle (TFFM) weight were developed from data of 33 beef cows. Animals varied in weight (385 to 749 kg), age (3 to 10 yr), and fatness (.13 to 2.54 cm). A four-terminal impedance meter/plethysmograph measured resistance and reactance on the live animals, exsanguinated (bled) animals, and on th...
