    Notes: Abstract  Data from a direct current resistivity survey and geologic logs from boreholes were used to map the top of permafrost at a remote air force installation in Alaska. This study resulted from a remedial investigation that was conducted at Eielson Air Force Base near Fairbanks, Alaska, under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) regulations. The depth and continuity of the permafrost was important in determining the fate of petroleum contamination that was inadvertently discharged to the ground during earlier air force operations. The results indicate that the top of permafrost forms a highly irregular surface. In general, however, the top of permafrost forms a diagonal ridge at the center of the contour grid that is bordered on each side by troughs.

    Characteristics of the myocardial PM-FABP: Effect of diabetes mellitus (1997)

    Notes: Abstract Properties of the myocardial PM-FABP were studied in normal and STZ-diabetic rats. The fluorescent fatty acids trans-parinaric and cis-parinaric acids were used as analogs of straight-chain (saturated) and kinked-chain (unsaturated) fatty acids respectively. Parinaric acid binding was sensitive to trypsin. Trans-parinaric acid binding was more sensitive to this protease than the binding of cis-parinaric acid. Based on the difference in sensitivity of parinaric acid binding we believe that there are two separate binding sites associated with myocardial PM-FABP; one for unsaturated fats and the other for saturated fats. Diabetes enhanced both cis- and trans-parinaric acid binding capacity in cardiomyocytes; cis-parinaric acid by 2 fold and trans-parinaric acid by 2.6 fold. In addition, there was a concomitant accumulation of free fatty acids and triglycerides in the hearts of the diabetic animals. There was a 2.2 fold increase for fatty acids and a 1.6 fold increase for trigylcerides. This association between myocardial fatty acid build-up and enhanced myocardial PM-FABP during diabetes suggest that this carrier protein might have contributed to lipid accumulation in the hearts of the diabetic rats.
