Cerebral blood flow (CBF) was measured with the 133Xenon inhalation technique and forehead skin flow with laser Doppler, before and twice after 0.3 milligram/kilogram of cocaine hydrochloride and a placebo given intravenously to six cocaine abusers, during two visits, separated by a minimum of one week. After cocaine, subjects showed significant increases(More)

1 ABSTRACT We describe the Interaction Region (IR) for the PEP-II project[l], a collaboration of SLAC, LBNL, and LLNL. The near IR region inboard of 3 m from the interaction point (IP) is designed to focus the 3.1 GeV low-energy beam (LEB) and bring it into head-on collision with the 9 GeV high-energy beam (HEB). We describe the overall design parameters of(More)
BACKGROUND Relative to plant-based foods, animal source foods (ASFs) are richer in accessible protein, iron, zinc, calcium, vitamin B-12 and other nutrients. Because of their nutritional value, particularly for childhood growth and nutrition, it is important to identify factors influencing ASF consumption, especially for poorer households that generally(More)
Age and portion size have been found to influence food intake in American children but have not been examined in an international context.

Using a within-subjects crossover design in a classroom setting, 173 children in(More)
Over the past two decades, the importance of addressing the complexity of the food system in ways that draw on new approaches to knowledge generation and new research paradigms has attracted significant attention (1, 2). This research topic explores the nexus of public health, food systems, food behavior, and food ways, focusing on belief systems, values,(More)
Inhabitants of the high-mountain Andes have already begun to experience changes in the timing, severity, and patterning of annual weather cycles. These changes have important implications for agriculture, for human health, and for the conservation of biodiversity in the region. This paper examines the implications of climate-driven changes for native and(More)
