PURPOSE We aimed at determining the cutoff value of waist circumference with respect to its ability to reflect insulin resistance in a Korean population. MATERIALS AND METHODS A total of 8,817 subjects aged 40 years and over were analyzed. Insulin resistant individuals were defined as those who had the highest quartile value of the homeostasis model assessment of insulin resistance (HOMA-IR) ...

An antimicrobial-surface kinetic test which maximizes probability of cell-to-surface contact has been developed. The measurement of rate of kill by a nonleaching antimicrobial surface is based on the number of surviving bacterial cells at specific times of exposure to various amounts of total treated surface area of test substrate. This method gives information for direct comparison of rate of ...

The aim of this study was to explore the effects of different density treatments on potato spatial distribution and yield in spring and fall. Plant density influenced yield and composition, horizontal, and vertical distribution distances between potato tubers, and spatial distribution position of tuber weights. The results indicated that: (1) Spring potato yield had a convex quadratic curve rel...

We report that planar chiral structures affect the polarization state of light in a manner similar to three-dimensional chiral (optical active) media. In experiments with artificial metal-on-silicon chiral planar gratings of 442 wallpaper group symmetry, containing millions of chiral elements per square centimeter, we observed rotation of the polarization azimuth in excess of 30 degrees of ligh...

Aerosols of ozone have been generated in a collisional cooling cell and observed over a small temperature range via FTIR spectroscopy, with the phase transition from the vapour taking place in the range 80-84 K. The condensed phase bands at 1038 cm(-1) (nu3) and 2105 cm(-1) (nu1+nu3) were assigned to the liquid phase. Aerosols were also generated from mixtures of ozone and HCl. In the presence ...

El presente trabajo tuvo como objetivo evaluar la humedad del suelo en cuatro ambientes: bosque nativo (Cerrado de Mata Atlântica), pastizal, plantación pino y con cultivo. Para análisis contenido agua el fue necesario colectar mensualmente 20 muestras indeformadas por cada tipo cobertura, cinco franjas profundidad 0-5 cm, 5-30 30-50 50-80 cm 80-100 cm. estudio reveló que franja superficial tie...

Trees in cropped fields may improve nitrogen (N) use efficiency by intercepting leached N, but crop yield will be reduced if the trees compete strongly with crops for N. Ideal trees for intercropping will take up N from deeper soil layers not accessed by the crop species. Spatiotemporal aspects of tree nitrogen capture niches were investigated within a hedgerow intercropping system by placing 1...

In biocatalytic conversions, substrates and products may display inhibitory or toxic effects on the biocatalyst. Rhodococcus erythropolis 1awq could further remove sulfur from hydrodesulfurized diesel oil, and the biodesulfurization was enhanced by the surfactant Tween 80. Tween 80 was shown to decrease the product concentration associated with the cells, reducing product inhibition.
