Blood Glucose Testing

Consumers and health care professionals expect blood glucose monitoring systems to consistently generate results that are close to actual blood glucose levels. Numerous environmental, physiologic, and operational factors can affect system performance, yielding results that are inaccurate or unpredictable. This study examined the effect of one factor—high altitude—on the performance of seven blood glucose monitoring systems. One of the systems overestimated blood glucose results; the other six systems underestimated blood glucose values (more than the expected variance). The findings of this study support previous reports of altered blood glucose monitoring system performance at high altitude. Diabetes educators can use this information when counseling consumers who reside or who plan to visit locations at high altitude.

AbstractThe Hα filtergrams obtained at Tjan-Shan High Altitude Observatory near Alma-Ata (Moscow University Station) were measured in order to specify the bright rims contrast at different points along the line profile (0.0; ± 0.25; ± 0.5; ± 0.75 and ± 1.0 Å). The mean contrast value in the line center is about 25 percent. The bright rims interpretation as the bases of magnetic structures supporting the filaments is suggested.

All serious electron microscopists at one time or another have been concerned with the cleanliness and freedom from artifacts of thin film specimen support substrates. This is particularly important where there are relatively few particles of a sample to be found for study, as in the case of micrometeorite collections. For the deposition of such celestial garbage through the use of balloons, rockets, and aircraft, the thin film substrates must have not only all the attributes necessary for use in the electron microscope, but also be able to withstand rather wide temperature variations at high altitude, vibration and shock inherent in the collection vehicle's operation and occasionally an unscheduled violent landing.Nitrocellulose has been selected as a film forming material that meets these requirements yet lends itself to a relatively simple clean-up procedure to remove particulate contaminants. A 1% nitrocellulose solution is prepared by dissolving “Parlodion” in redistilled amyl acetate from which all moisture has been removed.
