BACKGROUND AND PURPOSE Dynamic methods of measuring cerebral autoregulation have become an accepted alternative to static evaluation. This article aims to describe a set of data collected from healthy volunteers by a dynamic method, the purpose being to qualify and quantify expected results for those who may be designing a study using this technique.

In vitro L-arginine enhanced natural-killer (NK) and lymphokine-activated-killer (LAK) cell activity; this cytotoxicity was mediated by CD56+ cells. In vivo arginine supplements (30 g/day for 3 days) increased the number of circulating CD56+ cells by a median of 32% in eight volunteers (p less than 0.01); this increase was associated with a mean rise of 91%(More)
Carotid endarterectomy has been shown to reduce the long-term risk of stroke in selected patients. The present study was designed to examine cognitive function and health related quality of life in a series of carotid endarterectomy patients. One hundred and nine patients undergoing carotid endarterectomy were assessed before surgery and at 6 months post op(More)
A. COMPUTER SYNTHESIZED TWO EXPERIMENTS HOLOGRAMS-In a previous report, we derived a new method for recording a complex function in the form of a real non-negative function. The new method has advantages over the conventional holographic method because it does not require a reference signal or a biasing constant in recording the complex wave front of an(More)
