Assessment of water resource contamination by pesticides in vegetable-producing areas in Burkina Faso.

This study proposes a comprehensive approach to investigate water resource contamination by pesticides under the specific climatic and hydrological conditions of the Sudano-Sahelian climate. Samples were collected from traditional wells, boreholes, and a lake in Burkina Faso. A multiresidue analysis was developed for 25 pesticides identified during field surveys.

Economic evaluation of voice recognition for the clinicians' desktop at the Naval Hospital Roosevelt Roads.

This study investigated the voice recognition (VR) pilot project conducted at the Naval Hospital Roosevelt Roads during 1996 and 1997. The objective of the analysis was to determine the viability and economic benefits of using a commercial, off-the-shelf VR application as a clinician's input device for transcribing clinical encounter notes. Results show that VR technology provides numerous benefits, such as resulting in more thorough clinical encounter notes, eliminating the need to hire medical transcriptionists, and reducing graphic user interface overload on the Windows-based Military Health Service Systems.

Regulation of the alpha 2A-adrenergic receptor in the HT29 cell line. Effects of insulin and growth factors.

The density of the alpha 2A-adrenergic receptor in the HT29 cell line, a human colonic adenocarcinoma, increases when the cells are placed in fetal calf serum (FCS)-free culture medium and decreases again, in a concentration-dependent manner, when they are re-exposed to FCS. In an attempt to identify the FCS components responsible for this phenomenon, we examined the effect of insulin and of various growth factors on receptor expression. Incubation of HT29 cells with insulin resulted in a time- and dose-dependent lowering of the alpha 2-adrenergic receptor number.
