1. Three experiments were performed to study the effects of amino acid imbalance on the growth of genetically lean (LL) or fat (FL) male chickens from 28 to 42 d of age. In experiment 1, five concentrations of digestible lysine were compared (4.75, 6.75, 7.75, 8.75 and 9.75 g/kg). In experiment 2, four concentrations of digestible arginine were compared(More)
BACKGROUND Pulmonary endothelium has metabolic functions including the conversion of angiotensin I to angiotensin II by angiotensin-converting ectoenzyme (ACE). In this study, we have validated an indicator-dilution technique that provides estimations of dynamically perfused capillary surface area (DPCSA) in humans, and we have characterized pulmonary(More)
Proliferation of vascular pericytes (PCs), smooth muscle-like cells found in the distal microvasculature, contributes to vascular remodeling in pulmonary hypertension. The factors controlling lung PC quiescence in normal states are poorly understood. We demonstrate that exogenous heparin and heparan sulfate proteoglycans inhibit rat lung PC proliferation in(More)
Platelet-activating factor (PAF) is released from activated leukocytes and endothelial cells in sepsis, lung injury, and the adult respiratory distress syndrome. With these disorders, pulmonary hypertension develops, partly due to muscularization of the microvasculature by proliferation of pericytes. PAF may be a mediator of this process. Therefore, we(More)
In this paper we cast DRM in a setting that allows us to model a number of current approaches as games. The DRM game is partitioned into two subgames, one that considers the game associated with content acquisition, and a second that considers how a consumer uses the content, along with a vendor's response to this usage. Examples are provided in order to(More)
—The routing problem in Wireless Mesh Networks is concerned with finding " good " source-destination paths. It generally faces multiple objectives to be optimized, such as i) path capacity, which accounts for the bits per second that can be sent along the path connecting the source to the destination node, and ii) end-to-end delay. This paper presents the(More)
