Etioplasts, Prolamellar Bodies, Saponins, Chromatography Prolamellar body tubules in etioplasts are composed mainly of two saponins. The determination of these saponins in leaves, etioplasts or subfractions of etioplasts is re­ commended to evaluate the concentration of these tubules in a given fraction. Using a densitometer after TLC-separation of the saponins measurements are carried out in a...

We performed this study to enable a reliable transition for clinical participants and patients from GE Lunar Prodigy Hologic Horizon A dual-energy X-ray absorptiometry (DXA) scanner assess the reproducibility of measurements made on new DXA scanner. Forty-five older adults had one spine, hip, total body scan 2 scans, with repositioning, Linear regression models were used derive cross calibratio...

Density and Speed of sound have been measured for pure components such furan, (DMF) 2-5-dimethylfuran, MDEA (n-methyldiethanolamine), DEG (diethylene glycol), TEG (triethylene DMA (dimethylacetamide) using Anton Paar (DSA-5000) vibrating U-tube densitometer in a temperature range 278.15 to 343.15 K ambient pressure (100 kPa). density speed furan + MDEA, DEG, TEG, 303.15 whereas DMF DMA, the is ...

Introduction: Dual energy x-ray absorptiometry (DEXA) is one of the most widely used methods measuring periprosthetic bone mineral density (BMD). Several reports have presented the precision of DEXA when used at the hip, whereas similar reports on factors influencing the precision at the knee are sparse. There are two noticeable aspects when measuring BMD at the knee. First, no software specifi...
