The dinner last night we shall all remember for a long time. We were fortunate enough to hear three Federal Reserve chairmen—each of them a giant in his own way—and a reply from Don Kohn that was not only insightful and thoughtful but moving too. Tributes are one thing, but the Bank of England puts its money where its mouth is. Alan Greenspan originally loaned Don Kohn to the Bank, as we couldn...

Relatively high deposition of nitrogen (N) in the northeastern United States has caused concern because sites could become N saturated. In the past, mass-balance studies have been used to monitor the N status of sites and to investigate the impact of increased N deposition. Typically, these efforts have focused on dissolved inorganic forms of N (DIN = NH4-N + NO3-N) and have largely ignored dis...

Here we report on three years (1996-1998) of measurements of organic and inorganic nitrogen (N) fluxes to and from Green Lakes Valley, a high-elevation ecosystem in the Colorado Front Range of the Rocky Mountains. Nitrate-N (NO3−N) was the dominant form of N in both precipitation and streamwater. Annual precipitation contained 52% NO3−N, 32% ammonium-N (NH4−N), 9% dissolved organic N (DON), and...

Dissolved organic matter (DOM) is an important factor in aquatic ecosystems, which is involved in a large variety of biogeochemical and ecological processes, and recent literature suggests that it could be strongly affected by agriculture in different climates. Based on novel monitoring techniques, we investigated the interaction of climate and agriculture effects on DOM quantity and quality. T...

Trichothecene mycotoxins such as deoxynivalenol (DON) are known to modulate the immune function, but to this date only few studies have been conducted with farm animals, especially pigs, which are regarded as most susceptible to this mycotoxin. Mitogen-stimulated proliferation of porcine blood lympho­ cytes was measured using two different assays, the MTT cleav­ age (metabolic activity) and the...

Deoxynivalenol (DON) is one of several mycotoxins produced by certain Fusarium species that frequently infect corn, wheat, oats, barley, rice, and other grains in the field or during storage. It is a toxic byproduct of Fusarium head blight in grains and feeds. Potential human exposure to DON may occur from ingestion of products made from contaminated grains. It has been detected in buckwheat, p...

The trichothecene mycotoxin deoxynivalenol (DON) is a contaminant of crops worldwide and known to cause adverse health effects in exposed animals and humans. A small survey reported the presence of DON in maize samples in Bangladesh, but these data are insufficient to assess human exposure, and also, biomonitoring data are still scarce. The present study applied biomarker analysis to investigat...

Introduction: Plusieurs facteurs font obstacles au don de sang dans les pays en développement. La présente étude avait pour objectifs d'analyser les connaissances, attitudes et pratiques de la population de Kisangani relatives au don de sang et d'identifier les obstacles au don de sang afin de guider la planification des activités de promotion du don de sang. Méthodes: L' enquête a été réalisée...
