Red Cell Lead, Whole Blood Lead, and Red Cell Enzymes*

Simultaneous assay of blood lead (Pb-B) and red cell lead (Pb-Rbc) in 123 samples from 104 urban and suburban students, ages 10-18, shows the ratio of concentration (Pb-Rbc)/(Pb-B) to increase as the hematocrit decreases. On direct assay in 40 samples, plasma lead (Pb-P) was fixed in a narrow range. In 28 students with Pb-Rbc >40 mug/100 ml, the mean red cell 2,3-diphosphoglycerate (2,3-DPG) wa...

Green Homeowners as Lead Adopters: Sustainable Living and Green Computing

In this paper, we explore opportunities for green computing, drawing on our ethnographic study of 35 green households in the United States. We begin by discussing recent shifts in Western environmentalism and the growth of green consumerism. We then explore green social networking processes and how these relate to perceptions of corporations, openness to new technological solutions, and our par...

Lead aVR--the neglected lead.

The aVR is often neglected lead. It is an unipolar lead facing the right superior surface. As all the depolarisations are going away from lead aVR, all waves are negative in aVR (P, QRS, T) in normal sinus rhythm. In dextrocardia, (True and technical) the p is upright in aVR. The lead aVR is a very important lead in localisation of Coronary Artery Disease. In the presence of anterior ST elevati...
