We examine the hypothesis that the efficiency of executive control processes is less stable
over time in older than younger adults. An age-related decrease in the efficiency of executive …

Blood vessels and nerves often follow parallel trajectories, suggesting that distal targets use
common cues that induce vascularization and innervation. Netrins are secreted by the floor …

Background—Stent revascularization is perceived as superior to balloon angioplasty and
surgical revascularization, but the paucity of stent publications precludes even historical …
